    2005-01-01

    Hepatocellular carcinoma is one of the most common cancer worldwide, primarily affecting those in regions with a high prevalence of viral hepatitis. However, the metastasis of hepatocellular carcinoma to the oral cavity is a rare phenomenon. This report presents a case of metastatic hepatocellular carcinoma in the left mandibular angle and ramus region of a 62-year-old man. Panoramic radiograph revealed an ill-defined radiolucent lesion extending from the retained root of the mandibular left second molar into the ascending ramus. The lesion had irregular and ill-defined margins.

    Hepatocellular carcinoma (HCC) is a common cause of cancer mortality. Hepatitis B and C viruses, aflatoxin and alga toxin in the contaminated drinking water are the major etiological factors. Rapidly progressing medical imaging has resulted in the improved treatment results. Surgical resection has a major role for influencing prognosis of HCC. Local cancer therapies based on the advances in early diagnosis are progressing rapidly. Multimodality combination and sequential treatment has proved effective, unfortunately systemic chemotherapy for HCC remains disappointed. All of these have resulted in the improved prognosis of HCC.

    Fibrolamellar hepatocarcinoma is a rare neoplasm diagnosed by computed tomography and confirmed by anatomo-pathological examination. We report a case of a patient admitted at Hospital Mater Dei in Belo Horizonte, MG, Brazil, due to fibrolamellar hepatocarcinoma, and discuss the clinical, radiological and pathological features of this disease. The conclusions reinforce the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms. (author)

    We performed dynamic CT in 30 cases of hepatocellular carcinoma, and concluded as below. Detecting the stain in the early phase of the dynamic series, it is possible to make a diagnosis of hepatocellular carcinoma. The dynamic CT is effective in a case of small hepatocellular carcinoma in which it is difficult to gain an accurate diagnosis in the routine CT study. The dynamic CT is also effective in the differential diagnosis of hepatic lesions, as other hepatic lesions such as hemangioma and metastatic liver cancer show different patterns compared with hepatocellular carcinoma.

  9. Hepatocellular carcinoma localized in the bile duct lumen: two case report

    Bae, Kyeung Kug; Chang, Jay Chun [Yeungnam Univ. School of Medicine, Seoul (Korea, Republic of)

    1998-10-01

    Intrabile duct tumor growth of hepatocellular carcinoma is an uncommon manifestation, but intraluminal bile duct hepatocellular carcinoma without primary hepatic parenchymal lesions is extremely rare. To our knowledge, only a few case reports have been published. We encountered two cases of primary hepatocellular carcinoma arising in the bile duct;serum alpha-fetoprotein levels were within the normal limits. Both showed the following characteristic radiologic features: (1) Cholangiography revealed filling defects within the dilated bile duct; (2) two-phase abdominal CT showed enhancement during the arterial-dominant phase and washout during the tissue equilibrium phase, as in typical HCC; and (3) hepateic arteriography revealed hypervascular tumor staining. Surgery was performed and the resected specimen showed no detectable primary hepatic parenchymal mass;on the basis of the pathologic finding, intraluminal bile duct hepatocellular carcinoma was confirmed. We cautiously assume that this peculiar type of HCC may arise primarily from bile duct mucosa.=20.

    With the advent of gray scale ultrasonographic equipment, the parenchymal disease of liver is more easily evaluated. Ultrasonography is a non-invasive technique, different from angiography, and performed without discomfort to patient. And also ultrasonography can be used in assessing the liver in cases showing equivocal scintigraphy and in differentiation of solid and cystic masses, first detected on scintigrams. Therefore, the complementary use of ultrasonography, Tc-99m-sulfur colloid scan and angiography provides better diagnostic accuracy for the detection of hepatocellular carcinoma, and moreover, sequential ultrasonographic studies in the same patient are valuable of following the course of hepatocellular carcinoma and monitoring the effectiveness of therapy for hepatocellular carcinoma. In thirty patients with histologically proven hepatocellular carcinoma, an analysis of ultrasound manifestation is made and the results are as follows; 1. Ultrasound manifestation of hepatocellular carcinoma by gray scale showed four different sonographic patterns including discrete echo free, discrete echogenic, ill defined echogenic and mixed patterns. 2. The size of hepatocellular carcinoma by ultrasonographic measurement was larger than 5 cm in diameter in 28 cases. 3. In 7 cases performed with angiography, all echogenicities of hepatocellualr carcinoma were correlated with the findings of vascularity of angiography. 4. In cases combined with liver cirrhosis, the sonographic pattern of hepatocellular carcinoma appeared to be discrete or ill defined echogenic patterns.

    of synchronous gastric NEC and hepatocellular carcinoma in a patient with several other precancerous lesions is presented. The patient had anaemia, and a gastric tumour and two duodenal polyps were identified on upper endoscopy. A CT scan of the abdomen revealed several lesions in the liver. The lesions were...... invisible on B-mode sonography and real-time sonography fused with CT was used to identify and biopsy one of the lesions. Histology showed hepatocellular carcinoma. A literature search showed that only one case of a hepatocellular carcinoma synchronous with a gastric NEC has been reported previously. TRIAL...

  13. CT of hepatocellular carcinoma

    Nakamura, H; Tanaka, T; Sai, H; Kawamoto, S; Morimoto, K [Osaka Univ. (Japan). Faculty of Medicine

    1982-06-01

    CT was investigated in 125 cases of hepatocelluar carcinoma and 47 cases of metastatic hepatic neoplasm. The entire contour of each tumor was traced and the average CT value in the tumor was estimated. As a result, the CT value for hepatocellular carcinoma tended to be higher on plain CT and also after contrast enhancement. The CT findings seen frequently were as follows: capsule in 76 cases (60.8%) and septum in 67 cases (53.6%); tumor thrombus in portal vein in 39 cases (31.2%) and that in inferior vena cava in 3 cases (2.4%); localized enlargement of hepatic bile duct in 24 cases (19.2%). These findings were rarely seen in the cases of metastatic hepatic neoplasm. As a relatively outstanding feature of hepatic metastases, a double contour, like concentric circles or contour lines, with a relatively large inner circle or contour line, was found in 21 cases (44.7%). By paying attention to the change of CT value on contrast enhancement and the characteristic image of each case, hepatocellular carcinoma could be differentiated from metastatic hepatic neoplasm with high probability.

    1994-01-01

    Since 1956, 388 autopsy cases of hepatocellular carcinoma (HCC) have been obtained at the Hiroshima Red Cross and A-Bomb Survivors Hospital, which consisted of those of proximately exposed 52 A-bomb survivors (mean age, 63.8 years), 105 distally exposed A-bomb survivors (mean age, 64.2 years), and the other 231 non-exposed patients (mean age, 60.6 years). Since 1985, the incidence of HCC tended to be higher in both proximately and distally exposed groups than the non-exposed group. There was no consistent tendency for the incidence of HCC by ages at autopsy and A-bombing. The incidence of liver cirrhosis was approximately 2 times higher in males than females in the non-exposed group, although no gender difference existed after 1981. In the exposed group, the incidence was similar in male and female groups. Approximately 90% of HCC patients had coexistent liver cirrhosis. Liver cirrhosis was associated with HCC in 50-60%. No significant differences in these incidences were observed between the exposed and non-exposed groups. The proportion of liver cirrhosis associated with HCC became constant in patients over the age of 40 in the non-exposed group. In the exposed group, on the other hand, the proportion reached the peak in those in their fifties and sixties. Survival time tended to be longer in the exposed group than the non-exposed group. The patients in the non-exposed group tended to have histologically atypical type and metastases, as compared with those in the exposed group. (N.K.)

  16. Spontaneous regression of a large hepatocellular carcinoma: case report

    Alqutub, Adel

    2011-01-01

    Full Text Available The prognosis of untreated advanced hepatocellular carcinoma (HCC is grim with a median survival of less than 6 months. Spontaneous regression of HCC has been defined as the disappearance of the hepatic lesions in the absence of any specific therapy. The spontaneous regression of a very large HCC is very rare and limited data is available in the English literature. We describe spontaneous regression of hepatocellular carcinoma in a 65-year-old male who presented to our clinic with vague abdominal pain and weight loss of two months duration. He was found to have multiple hepatic lesions with elevation of serum alpha-fetoprotein (AFP level to 6,500 µg/L (normal <20 µg/L. Computed tomography revealed advanced HCC replacing almost 80% of the right hepatic lobe. Without any intervention the patient showed gradual improvement over a period of few months. Follow-up CT scan revealed disappearance of hepatic lesions with progressive decline of AFP levels to normal. Various mechanisms have been postulated to explain this rare phenomenon, but the exact mechanism remains a mystery.

    2002-01-01

    Objective: This study aimed at documenting the spectrum of clinico pathological variations in hepatocellular carcinoma (HCC). Design: It was a retrospective study. Place and duration of Study: This study was conducted at the Institute of Nuclear Medicine and Oncology (INMOL) Hospital, Lahore from March 1997 to December 2000. Patients and Methods: The profiles of 118 patients with a biopsy proven hepatocellular carcinoma were analyzed in this period. The data collected was age, sex, clinical presentation and laboratory investigations including liver function tests, alpha fetoprotein and hepatitis profile. Results: Weight loss, jaundice and right upper quadrant abdominal pain were the main presenting symptoms. Out of 118 patients, alpha fetoprotein values were raised in 63(53.38%) patients 106 (89.83%) patients were found to have or have had HBV infections, and 92 (77.96%) patients were anti-HCV positive. Eighty-three (70.33%) patients were cirrhotic. History of alcohol abuse was bound in three patients. Conclusion: The common association of HCC with cirrhosis and hepatitis B and C suggests that vaccination against HBV on nationwide basis can decrease prevalence of this malignancy. There is a need to generate public awareness regarding the transmission of these viruses. Early diagnosis and intervention is also important to the successful management of HCC. (author)

  18. Case report evidence of relationships between hepatocellular carcinoma and ochratoxicosis.

    Ahmed S Ibrahim

    Full Text Available PURPOSE: The incidence of Hepatocellular carcinoma (HCC is on the rise, but what is causing that trend has remained a mystery. Mycotoxins are almost entirely ignored health problems, and sometimes actually naively belittled in advanced medical care. Ochratoxin A (OTA is one of the most abundant food contaminating mycotoxins worldwide that is carcinogenic, but no studies have evaluated its levels in HCC patients. Therefore, this study was designed to monitor the presence of OTA in the serum of HCC patients and to quantify the strength of the association between OTA and HCC. METHODS: We conducted a case control-based study on 61 participants. Thirty-nine were HCC cases identified between 2010 and 2012 and individually matched by age, sex, residence and date of recruitment to 22 healthy controls. Serum OTA and alpha-fetoprotein levels were measured by using high-performance liquid chromatography (HPLC and enzyme-linked immunosorbent assay, respectively. RESULTS: HPLC analysis of 61 serum samples indicated that the highest incidence of elevated OTA was found in the HCC group and was 5-fold higher than in the control group. The concentration of OTA in the HCC group ranged between 0.129 and 10.93 ng/mL with a mean value±SD of 1.1±0.3 ng/mL, while in the normal group it ranged between 0.005 and 0.50 ng/mL with a mean value±SD of 0.201±0.02 ng/mL. The odds ratio for HCC patients presenting OTA levels above the cut-off of 0.207 (calculated by the receiver operating characteristic curve was 9.78 (95% confidence interval = 2.9095-32.9816, P = 0.0002 with respect to normal controls, suggesting that HCC is 9.8 times as frequent in the exposed group to OTA. CONCLUSION: Our results reveal a strong association between the presence of OTA and HCC, which may offer a coherent explanation for much of the descriptive epidemiology of HCC and suggest new avenues for analytical research.

    Metastasis to the pituitary gland is extremely rare and is often detected incidentally by symptoms associated with endocrine dysfunction. Breast and lung cancer are the most common primary metastasizing to pituitary gland. Metastasis from hepatocellular carcinoma to the pituitary gland is extremely rare, with only 10 cases having been previously reported. We present here the first case of pituitary metastasis of hepatocellular carcinoma presenting with panhypopituitarism diagnosed by magnetic resonance imaging. We report the case of an 80-year-old Japanese woman who presented with the sudden onset of hypotension and bradycardia after having previously been diagnosed with hepatocellular carcinoma. Based on low levels of pituitary hormones, she was diagnosed with panhypopituitarism caused by metastasis of the hepatocellular carcinoma to the pituitary gland. Magnetic resonance imaging with arterial spin-labeling was effective in the differential diagnosis of the intrasellar tumor. The patient died despite hormone replacement therapy because of hypovolemic shock. Metastasis to the pituitary gland causes various non-specific symptoms, so it is difficult to diagnose. The present case emphasizes the importance of diagnostic imaging in identifying these metastases. Clinicians should consider the possibility of pituitary metastasis in patients with malignant tumors who demonstrate hypopituitarism.

    Hepatocellular carcinoma is the most common primary malignant tumor of liver. Metastasis of hepatocellular carcinoma occurs in various organs, but metastasis to the ovary is extremely rare. We report MRI finding of metastatic hepatocellular carcinoma of the ovary in a 37-year-old woman who was treated hepatocellular carcinoma transarterial chemoembolization and radiofrequency ablation a year ago. Pelvic MRI revealed a mass in pelvic cavity with heterogeneous signal intensity and centripetal enhancement. Surgical excision and pathologic examination confirmed metastatic hepatocellular carcinoma in the ovary.

  5. Radiosensitivity of hepatocellular carcinoma

    Hennequin, C.; Quero, L.; Rivera, S.

    2011-01-01

    The frequency of hepatocellular carcinoma (HCC) is increasing in the western world and the role of radiotherapy is more and more discussed. Classically, hepatocellular carcinoma was considered as a radioresistant tumour: in fact, modern radio-biologic studies, performed on cell lines directly established from patients, showed that hepatocellular carcinoma has the same radiosensitivity than the other epithelial tumours. From clinical studies, its α/β ratio has been estimated to be around 15 Gy. Radiosensitivity of normal hepatic parenchyma is now well evaluated and some accurate NTCP models are available to guide hepatic irradiation. The biology of hepatocellular carcinoma is also better described: the combination of radiotherapy and targeted therapies will be a promising approach in the near future. (authors)

Both severe and non-severe adverse events were reported, but the true nature and extent of harm was difficult to asses. AUTHORS' CONCLUSIONS: At present, there is no evidence to recommend or refute cryotherapy for patients with hepatocellular carcinoma...

  7. US Findings of Small Hepatocellular Carcinoma : Analysis of 274 cases

    Jung, Hye Weon; Lee, Hak Jong; Kim, Tae Kyung; Han, Joon Koo; Choi, Byung Ihn [Seoul National University College of Medicine, Seoul (Korea, Republic of)

    1996-12-15

    The prognosis of hepatocellular carcinoma (HCC) is very poor because of the difficulty in early detection and association with the liver cirrhosis. Because the surgical resection or transarterial chemoembolization is the most effective treatment, the detection of the small HCCs is important. The purpose of this study was to assess the frequencies of a suggestive sonographic morphology of small HCC. In 222 patients with small HCCs less than 5 cm in diameter, each sonographic feature of 274 nodules was analyzed. HCCs were diagnosed pathologically (n = 83) or by elevated serum alpha-fetoprotein levels and characteristic angiographic {delta} Lipiodol CT findings (n = 191). The diameters of the tumors were as follows : {<=} 2 cm (n = 90),2{approx}3 cm (n = 87), and 3{approx}5 cm (n = 97). The frequencies of sonographic morphology of small HCCs including echo pattern, peripheral hypoechoic halo, lateral shadow, posterior acoustic enhancement, and the mosaic pattern were assessed. For statistical analysis of the differences of echo pattern, Chi-square test was used and for evaluation of the differences of the sonographic characteristics according to the tumor size, Friedman Two-Way ANOVA test was used. Overall, characteristics of small HCCs less than 5 cm were peripheral halo (70%), posterior enhancement (43%), and mosaic pattern (39%). In small HCCs less than 3 cm hyper echoic masses are more common than hypoechoic masses, which is different from previous peports. The smaller the mass, the more frequent the incidence of high or low echo pattern. Mixed echo pattern, peripheral halo, and mosaic pattern increased isoecho, lateral shadow, and posterior acoustic enhancement between 2 cm, 2{approx}3 cm, and 3{approx}5 cm size nodules.The understanding about the sonographic characteristics of small HCCs according to the size may be useful for the detection and characterization of the small HCCs

    Full Text Available A 3.10 kg, six-year old male green iguana (Iguana iguana suffered several weeks of decreased activity, loss of body weight, anorexia and change of skin colour. Physical examination revealed a cachectic depressed lizard, with marked pale mucous membranes. The complete blood count revealed a leukocytosis (46.5 × 109/l, elevated heterophils (23.25 × 109/l and azurophils (23.25 × 109/l, decreased haemoglobin concentration (29.00 g/l, low haematocrit (0.16 l/l and erythropenia (0.35 × 1012/l. Abnormalities of the plasma chemistry panel included increased activity of aspartate aminotransferase (6.05 μkat/l and creatinephosphokinase (217.91 μkat/l, increased concentrations of uric acid (321.58 μmol/l, phosphorus (4.04 mmol/l and bile acids (120.21 μmol/l, as well as a decreased concentration of glucose (3.72 mmol/l, cholesterol (0.637 mmol/l and triglycerides (0.09 mmol/l. A lateral radiograph revealed soft-tissue opacity present in the region of the liver. Magnetic resonance imaging showed a markedly enlarged left liver lobe distended caudally and displacing the other abdominal organs. The signal intensity of the liver parenchyma was slightly hyperintense, the ventro-medial part of the left lobe showed a hypointense signal. Endoscopic examination of the coelomic cavity revealed a greatly enlarged pale liver and the presence of a straw-coloured modified transudate. Based on histopathological examination of the liver hepatocellular carcinoma was diagnosed. Despite supportive treatment the patient died on the sixth day of hospitalisation.

    The authors report of a multicenter study on the diagnosis and interventional therapy of hepatocellular carcinoma (HCC).The first aim -diagnostic - was to evaluate the sensitivity of 4 imaging techniques, namely ultrasonography (US), Computed Tomography (CT), digital arteriography (DSA) and Lipiodol CT (LCT), in hepatocellular carcinoma detection. The accuracy of these techniques was also investigated in tumor staging, which is important for treatment planning.The second aim - treatment - consisted in assessing the therapeutic efficacy of intraarterial chemoembolization (CEAT) versus percutaneous ethanol injection (PEI) in non advanced hepatocellular carcinoma and of intraarterial chemoembolization versus no treatment (NT) in advanced hepatocellular carcinoma. Treatment efficacy was evaluated with the following randomized protocols

    Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective . However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experienced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction by anterior spinal arterial occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment

    Although the thyroid gland is one of the most vascular organs of the body, metastatic disease in the thyroid is encountered infrequently. However, at autopsy, the incidence rate of thyroid metastasis ranges from 1.25% to 24%. The primary sites are the kidney, lung, breast, and gastrointestinal tract. We report a rare case of a hepatocellular carcinoma metastatic to the thyroid gland. The patient had multiple palpable masses in the anterior and left lateral neck along the internal jugular chain on physical examination 9 months after the initial diagnosis of liver tumor. These masses were confirmed as metastasis from hepatocellular carcinoma by ultrasonography-guided 16-G core needle biopsy. We discuss the sonographic findings of thyroid metastasis and their use as an additional aid for differentiating between unknown primary tumor and thyroid metastasis.

    Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of leptomeningeal metastasis from hepatocellular carcinoma. We herein report a case of leptomeningeal metastasis from hepatocellular carcinoma in a 53-year-old woman with concomitant systemic metastases to the lung, bone, brain, kidney, adrenal gland, subcutaneous tissues, and abdominal pelvis. The neurological symptoms of the patient were relieved after treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy. To our knowledge this is the first report of leptomeningeal metastasis from hepatocellular carcinoma confirmed by cytology. Treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy was effective

    Hepatocellular carcinoma originating from the caudate lobe has a worse prognosis than other hepatocellular carcinoma in another segment of the liver. An isolated caudate lobe resection of the liver represents a significant technical challenge. Caudate lobe resection can be performed along with a lobectomy or as an isolated liver resection. There are very few reports about isolated caudate lobe liver resection. We report a case of successful isolated resection of hepatocellular carcinoma in the caudate lobe with excellent long-term survival. A 74 years old female with 8cm mass lesion in the caudate lobe without clinical or biochemical evidence of liver cirrhosis, serum alpha-fetoprotein 3.7 U/l, and negative hepatitis serology was evaluated for surgery. Complete resection of the lesion in 270minutes with Pringle maneuver for 13minutes was satisfactorily performed. Patient was discharged ten days after surgery without complications. Patient is currently asymptomatic, without deterioration of liver function and 48 month tumor free survival after the procedure. Isolated caudate lobe resection is an uncommon but technically possible procedure. In order to achieve a successful resection, one must have a detailed knowledge of complete liver anatomy. Tumor free margins must be obtained to provide long survival for these patients who have a malignancy in this anatomic location. Copyright © 2015. Published by Masson Doyma México S.A.

    With Development of Computed Tomography, detection of the Hepatocellular Carcinoma are easily performed and frequently used in the world. During 15 months, from December 1985 to February 1987, 59 patients with hepatocellular carcinoma were evaluated with computed tomography in department of radiology at Wallace Memorial Baptist Hospital. The results were as follow: 1. The most prevalent age group was 5th to 7th decades, male to female ratio was 4.9:1. 2. Classification with incidence of computed tomographic appearance of the hepatocellular carcinoma were solitary type 28 cases (48%), multinodular type 24 cases (40%), and diffuse type 7 cases (12%), Association with liver cirrhosis was noted in 22 cases (38%). 3. Inhomogenous internal consistency of hepatocellular carcinoma due to central necrosis were 35 cases (60%). Portal vein invasion by hepatocellular carcinoma was noted in 15 cases (25%), and particularly most common in diffuse type 4 cases (55%). 4. On precontrast scan, all hepatocellular carcinoma were seen as area of low density except for 3 cases(0.5%) of near isodensity which turned out to be remarkable low density on postcontrast scan. 5. In solitary type, posterior segment of right lobe was most common site of involvement 12 cases (43%). In diffuse type, bilobar involvement was most common, 6 cases (85%)

    Full Text Available Abstract Background Despite the apparent low incidence of cancer metastatic to the thyroid, autopsy and clinical series suggest it is more common than generally. Although lung, renal, and breast cancer are probably the most common primary sites, a number of cancers have been reported to metastasize to the thyroid synchronously with diagnosis of primary tumor or years after apparently curative treatment. Case presentation We report a rare case of a hepatocellular carcinoma metasatic to the thyroid. The patient presented seven months after original diagnosis and treatment with hepatic lobectomy with multiple neck lesions producing a mass effect on the trachea and bilateral lymphadenopathy. Fine-needle aspiration revealed highly anaplastic carcinoma, and immunohistochemistry confirmed hepatocellular carcinoma. The patient received total thyroidectomy as palliative therapy because of the presence of multiple recurrent lesions in the liver. Conclusion Clinicians should consider the possibility of metastatic cancer in each patient who presents with a new thyroid mass, especially those with a history of cancer, however remote. In cases where cytology or histology is not diagnostic, immunohistochemistry may be definitive in making the diagnosis.

    Transcatheter arterial chemoembolization (TACE) is known to be an effective palliative treatment for unresectable hepatocellular carcinoma (HCC). Serious complications, such as neutropenic sepsis and hepatic decompensation, are well known. A HCC rupture following TACE is a rare complication; however, it can be life threatening if it occurs. In a 75 year old male patient who subsequently developed capsular rupture of the lipiodol laden mass and several free intraperitoneal chemoembolization agents with hemoperitoneum, we report a case of a ruptured HCC that superficially located arterial enhancing and early wash out mass in the right hepatic dome following TACE.

    With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal disease including space occupying lesion are easily performed and frequently used in the world. Thrity five cases of histopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectively studied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoic pattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The margin of tumor is ill-defined in 19 cases (54%) and well defined in16 cases (46%). 3. The size of tumor by sonographic measurement was large than 5 cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases and multiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), and both lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25 cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) and tumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6 : 1 male predominence and the age ranges from 32 to 76 years with highest incidence in 5th and 6th decades.

  1. Hepatocellular carcinoma and impact of aflatoxin difuranocoumarin derivative system: A case report

    Ilić Miroslav

    2016-01-01

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is the most frequent type of liver malignancy. As a carcinogen, aflatoxin B1 (AFB1 causes HCC by inducing deoxyribonucleic acid adducts that lead to genetic changes in liver cells and may be the cause of HCC in up to 30% of cases. The incidence of HCC has been on the rise and is an issue in the countries of the Western Balkans. Case Outline. This paper presents a case of a 37-year-old woman who was diagnosed with HCC, without hepatitis B, hepatitis C, or liver cirrhosis. The patient consumed milk and dairy products in quantities of over two liters per day over the course of 20 years, which indicates the impact of aflatoxin in milk on HCC. A positive signal for the presence of AFB1 was detected by ELISA (enzyme-linked immunosorbent assay in-house using immunoperoxidase screening test. Conclusion. As carcinogenic difuranocoumarin derivative, aflatoxin B1 is the most likely cause of malignant transformation of hepatocytes, which resulted in hepatocellular carcinoma in this patient.

    To confirm the safety and effectiveness of techniques to assist radiofrequency ablation (RFA) for difficult cases, we retrospectively evaluated successful treatment rates, early complications and local tumor progressions. Between June 1999 and April 2009, a total of 341 patients with 535 nodules were treated as difficult cases. Artificial pleural effusion assisted ablation was performed on 64 patients with 82 nodules. Artificial ascites-assisted ablation was performed on 11 patients with 13 nodules. Cooling by endoscopic nasobiliary drainage (ENBD) tube-assisted ablation was performed on 6 patients with 8 nodules. When the tumors were not well visualized with conventional B-mode ultrasonography (US), contrast-enhanced US-assisted ablation with Levovist or Sonazoid or virtual CT sonography-assisted ablation was performed. Contrast-enhanced US-assisted ablation was performed on 139 patients with 224 nodules and virtual CT sonography-assisted ablation was performed on 121 patients with 209 nodules. In total, complete ablation was achieved in 514 of 535 (96%) nodules in difficult cases. For RFA with artificial pleural effusion, artificial ascites and ENBD, complete response was confirmed in all cases. For contrast-enhanced US- and CT sonography-assisted ablation, complete response was 95%. Early complications were recognized in 24 cases (4.5%). All cases recovered with no invasive treatment. Local tumor recurrence was investigated in 377 nodules of 245 patients, and 69 (18%) nodules were positive. Tumor recurrences in each assisted technique were 14.7% in artificial pleural effusion cases, 7% in artificial ascites, 12.5% in ENBD tube cases, 31% in virtual CT sonography, and 8.5% in contrast-enhanced US. Although local tumor progression needs to be carefully monitored, assisted techniques of RFA for difficult cases are well tolerated and expand the indications of RFA. Copyright (c) 2010 S.

  3. Radioembolization of hepatocellular carcinoma.

    Van de Wiele, Christophe

    2010-12-01

    In this review paper, available data on radioembolization of unresectable hepatocellular carcinoma (HCC) using commercially available radiopharmaceuticals, respectively (131)I-Lipiodol, Therasphere (glass-microspheres) and SIRspheres (resin-microspheres) are reviewed. In the palliative setting, (131)I-Lipiodol was shown to yield response rates of 17-92% which in patients with portal vein thrombosis (PVT) translate into a survival benefit as evidenced by a phase III randomized trial. Furthermore, in terms of efficacy, (131)I-Lipiodol is as efficacious as trans-arterial chemoembolization (TACE) but far better tolerated. In the adjuvant setting, improved recurrence-free and overall survival when compared to surgery alone have been reported but these results warrant confirmation by randomized prospective trials. Similar to (131)I-Lipiodol, when administered in a palliative setting, radioembolization using (90)Y microspheres was proven effective for selected cases of non-resectable HCC and well tolerated. Available data suggest that Therasphere treatment outperforms TACE both in terms of response as in terms of event-free survival in unresectable HCC. However, this finding needs confirmation by randomized prospective trials. Therasphere treatment was also shown to limit progression of HCC allowing potential candidates for orthotopic liver transplantation (OLT) more time to wait for donor organs as well as to downstage the HCC disease to such an extent that patients that were initially not, as yet become eligible for OLT with a gain in survival. Finally, Therasphere was shown to be safe and efficacious in HCC patients presenting with PVT, reason for which approval was granted for this indication by the FDA.

  4. Histopathology of hepatocellular carcinoma.

    2014-11-21

    Hepatocellular carcinoma (HCC) is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide. Its etiology is usually linked to environmental, dietary or life-style factors. HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed. Although this process is yet to be completely understood, this changing scenario also has impact on the material seen by pathologists, presenting them with new diagnostic dilemmas. Histopathologic criteria for diagnosing classical, progressed HCC are well established and known, but with an increase in detection of small and early HCCs due to routine screening programs, the diagnosis of these small lesions in core needle biopsies poses a difficult challenge. These lesions can be far more difficult to distinguish from one another than progressed HCC, which is usually a clear cut hematoxylin and eosin diagnosis. Furthermore lesions thought to derive from progenitor cells have recently been reclassified in the WHO. This review summarizes recent developments and tries to put new HCC biomarkers in context with the WHOs reclassification. Furthermore it also addresses the group of tumors known as combined hepatocellular-cholangiocellular carcinomas.

  5. Primary hepatic peripheral T-cell lymphoma mimicking hepatocellular carcinoma: a case report.

    Lee, Jisun; Park, Kil Sun; Kang, Min Ho; Kim, Yook; Son, Seung-Myoung; Choi, Hanlim; Choi, Jae-Woon; Ryu, Dong Hee

    2017-08-01

    Peripheral T-cell lymphomas (PTCLs) are aggressive neoplasms which may involve the liver. The imaging manifestations of hepatic lymphoma are highly variable and show overlapping appearances of numerous other hepatic diseases. As the management and prognosis of lymphoma differ markedly from those of other malignant diseases, prompt diagnosis and early effective treatment are very important. Here, we report an atypical case of primary PTCL not otherwise specified involving the liver that exhibited a solitary hepatic mass mimicking hepatocellular carcinoma (HCC) on CT. Liver biopsy is not commonly recommended in highly suspicious cases of HCC. However, in a patient without risk factors for HCC, consideration of other diagnostic possibilities is required and needle biopsy may be a more rational choice. An imaging approach, based on a careful review of clinical and laboratory findings is essential to prevent false-positive diagnosis of HCC and subsequent invasive treatment.

  6. Transhemangioma Ablation of Hepatocellular Carcinoma

    Radiofrequency ablation (RFA) is a well-established treatment modality in the treatment of early hepatocellular carcinoma (HCC) [1]. Safe trajectory of the RFA probe is crucial in decreasing collateral tissue damage and unwarranted probe transgression. As a percutaneous technique, however, the trajectory of the needle is sometimes constrained by the available imaging plane. The presence of a hemangioma beside an HCC is uncommon but poses the question of safety related to probe transgression. We hereby describe a case of transhemangioma ablation of a dome HCC.

    Nagashima, Tohru; Ryu, Takamasa; Watanabe, Yoshiji

    1985-01-01

    A 51-year-old male patient with hepatocellular carcinoma was treated preoperatively by fast neutron radiotherapy (910 rad/7 fractions/15 days) with a field of 8 x 6 cm. Radiation-associated liver function disturbance was scarcely observed. No side effect, such as loss of appetite and general fatigue, was encountered. According to the classification of Ohoshi and Shimosato, histological effect of radiation was graded as II sub(A). There is no preoperative fast neutron radiotherapy for hepatocellular carcinoma in Japan in the literature. (Namekawa, K.)

  9. Metastasis of hepatocellular carcinoma to the heart: unusual patterns in three cases with antemortem diagnosis.

    Lei, M H; Ko, Y L; Kuan, P; Lien, W P; Chen, D S

    1992-04-01

    Unusual patterns of cardiac metastasis were noted in three cases of hepatocellular carcinoma (HCC): one patient was noted to have a large right ventricular (RV) tumor mass with intracavitary growth and myocardial invasion; the second had massive pulmonary and left atrial (LA) metastasis; and the third patient had a right atrial tumor mass with concomitant RV and LA involvement. Tumor implantation to the RV without right atrial involvement and extensive myocardial invasion is unusual in HCC. The LA involvement is probably related to tumor growth from the pulmonary veins following massive metastasis to the lung, direct invasion of the atrial septum or tumor implantation via a subclinical right-to-left shunt through the patent foramen ovale. To the best of our knowledge, such unusual intracavitary metastases in HCC have not been reported previously. Cardiac metastasis, without local gross recurrence, may be one of the presentations after lobectomy in patients with HCC.

  10. Hepatocellular carcinoma presenting as an isolated sphenoid sinus lesion: a case report.

    Tandon, Shantanu; Nair, Arun; Sawkar, Anisha; Balasubramanya, A M; Hazarika, Diganta

    2012-01-01

    We report a rare case of a metastatic sphenoid sinus lesion originating from an undiagnosed hepatocellular carcinoma (HCC) in a 53-year-old man who presented with gradually progressive external ophthalmoplegia. Imaging showed a right sphenoid sinus lesion infiltrating the parasellar region. Although a primary sphenoid biopsy was inconclusive, positive hepatitis B surface antigen and CT-guided fine-needle aspiration cytology suggested an HCC. A repeat endoscopic biopsy from the sphenoid with immunohistochemistry confirmed the lesion to be metastatic HCC. Metastasis to the paranasal sinuses is extremely rare, and metastasis from a liver primary even more rare. Because of clinical and radiologic similarity between the primary and metastatic lesions, metastasis to the sphenoid sinus is often undiagnosed. Patients with features suggestive of sphenoid sinus malignancy should also be evaluated for the possibility of a metastatic tumor. In this article, we emphasize the rarity of the tumor, the unusual presenting symptoms, and problems with early diagnosis.

  11. Morphologic Subtypes of Hepatocellular Carcinoma.

    Torbenson, Michael S

    2017-06-01

    Hepatocellular carcinomas can be further divided into distinct subtypes that provide important clinical information and biological insights. These subtypes are distinct from growth patterns and are on based on morphologic and molecular findings. There are 12 reasonably well-defined subtypes as well as 6 provisional subtypes, together making up 35% of all hepatocellular carcinomas. These subtypes are discussed, with an emphasis on their definitions and the key morphologic findings. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-09-01

    Hepatocellular carcinoma has a growing incidence worldwide, and represents a leading cause of death in patients with cirrhosis. Nowadays, minimally invasive approaches are spreading in every field of surgery and in liver surgery as well. We retrospectively reviewed demographics, clinical, and pathologic characteristics and short-term outcomes of patients who had undergone minimally invasive resections for hepatocellular carcinoma at our institution between June 2012 and May 2016. No significant differences in demographics and comorbidities were found between patients in the laparoscopic (n = 24) and robotic (n = 22) groups, except for the rates of cirrhotic patients (91.7% and 68.2%, respectively, P = 0.046). Perioperative data analysis showed that the operative time (mean, 211 and 318 min, respectively, P robotic-assisted resections were related to less Clavien I-II postoperative complications (22 cases versus 13 cases; P = 0.03). As regards resection margins, the two groups were similar with no statistically significant differences in rates of disease-free resection margins. A modern hepatobiliary center should offer both open and minimally invasive approaches to liver disease to provide the best care for each patient, according to the individual comorbidities, risk factors, and personal quality of life expectations. Our results show that the robotic approach is a reliable tool for accurate oncologic surgery, comparable to the laparoscopic approach. Robotic surgery also allows the surgeon to safely approach liver segments that are difficult to resect in laparoscopy, namely segments I-VII-VIII. Copyright © 2017 Elsevier Inc. All rights reserved.

    From March 1977 to July 1979, 69 cases of angiograms of hepatocellular carcinoma were observed in Seoul National University Hospital. The findings of selective celiac and/or hepatic arteriography in total 69 cases of confirmed hepatocellular carcinoma, with clinical and laboratory findings, were analyzed. The summarized results are as follows; 1. Among 69 cases od hepatoma, 62 were male and 7 were female with sex ratio of 8.9 : 1. Peak incidence is 5th to 7th decades (72.5%). Epigastric pain, indigestion, and palpable mass in right upper quadrant were common symptoms and sign. Laboratory findings showed elevated serum alkaline phosphatase more than 5 Bodansky unit in 75.4%. Alpha-feto protein was positive in 65.2% of all the patients. 2 All 69 cases were classified into 31 cases of massive type, 22 cases of diffuse type, and 16 cases of nodular type, in accordance with angiographic gross anatomy. The frequency of angiographic findings were hypervascularities and tumor vessels (100%), tumor stainings (98.5%), arteriovenous shunt (71.0%), displacement of intrahepatic arteries (66.7%), vascular lakes and channel (59.4%). Encasement of hepatic artery and portal vein regurgitation was respectively 4 cases. Tumor mass in portal vein were 6 cases and tumor mass in hepatic vein was 1 case. 3. Intraarterial infusion of 5-FU was performed in 15 hepatoma patients, and the results were that angiographic improvement was demonstrated in 3 cases, no improvement in 8 cases, and incomplete infusion in 4 cases. 4. The selective celiac and/or hepatic angiograms are excellent diagnostic tools as well as therapeutic management for intraarterial infusion of anticancerous drugs.

    Vicente, R.; Garcia-Gutierrez, J. A.; Fernandez, A.; Santalla, F.

    2001-01-01

    Fibrolamellar hepatocellular carcinoma is an uncommon malignant tumor with characteristic clinical, radiological and histopathological features that is usually associated with a more favorable natural course and greater survival than more common variants of hepatocellular carcinoma. We describe an atypical case of a fibrolamellar hepatocellular carcinomas sowing aggressive behaviour in a 20-year-old woman. The lesion presented with massive ascites, and imaging studies revealed extensive peritoneal metastatic spread. (Author) 8 refs

  16. Diagnostic Approaches to Metastatic Hepatocellular Carcinoma of the Orbit.

    Geske, Michael J; Bloomer, Michele M; Kersten, Robert C; Vagefi, M Reza

    Orbital metastasis of hepatocellular carcinoma is exceedingly rare and caries a grave prognosis. Three cases of metastatic orbital hepatocellular carcinoma in which the primary tumor was initially unknown and the diagnostic challenges encountered are presented. With hepatocellular carcinoma, open biopsy and palliative tumor debulking has an increased bleeding risk due to the highly vascular nature of the tumor and coagulopathy associated with chronic liver disease. As an alternative, fine needle aspiration biopsy should be considered for hepatocellular carcinoma with a readily accessible mass and the availability of an experienced cytopathologist.

    To facilitate regionally specific liver cancer prevention and control, this study estimates the fraction of hepatocellular carcinoma (HCC) cases attributable to five major liver cancer risk factors by geographic region. Prevalence estimates of major HCC risk factors, including chronic infection with hepatitis B and hepatitis C, alcohol drinking, tobacco smoking, obesity, and diabetes, were extracted for each country from the literature, along with recent incidence and risk estimate data, to calculate regionally specific population attributable fractions. Overall, 44% of HCC cases worldwide were attributable to chronic hepatitis B infection, with the majority of cases occurring in Asia. Hepatitis C was responsible for 21% of cases. Lifestyle risk factors such as alcohol drinking and obesity were responsible for a larger percentage of cases in North America and Western, Central, and Eastern Europe. In addition, strong sex disparities were observed when looking at lifestyle risk factors, particularly tobacco smoking, in Asia and Africa. Prominent risk factors for HCC vary depending on the region. Our findings provide useful data for developing regionally specific guidelines for liver cancer prevention and control worldwide.

In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an

    We described the pathomorphological characteristics of 102 autopsy cases of Thorotrast (Th) related hepatic malignancies, and compared these to the features of non-Th-related cases. Among the 102 Th-related hepatic malignancies, 44 (43.1%) were cholangiocarcinoma (CHC), 39 (38.3%) were angiosarcoma (AGS), 16 (15.7%) were hepatocellular carcinoma (HCC), and 3 (2.9%) were double cancer. Grossly, the majority (91.7%) of Th-related CHC was located in the middle-peripheral portion of the liver. Th-related AGS was classified into four types: diffuse micronodular, multinodular, massive and mixed multinodular, and massive. Histologically, in CHC and HCC cases, there were no significant differences between Th-related and non-Th-related cases. AGS was characterized by two cell types (spindle-shaped cells and polyhedral cells) and three growth patterns (sinusoidal, carvernous, and solid). In non-cancerous areas, foci of varying degrees of sinusoidal dilatation with hyperplastic changes of sinusoidal lining cells were observed in all AGS cases and in some of the cases of Th-related CHC and HCC cases. In Th-related CHC cases, papillary proliferation of the epithelium of relatively large bile ducts was seen in 11 (29.7%) of the 37 cases, and proliferation of small bile ducts and/or bile ductules was seen in 9 (24.3%) of the 37 cases. However, similar histologic changes were also observed in the non-Th- related CHC cases. In Th-related HCC cases, mixed macro- and micronodular cirrhosis was superimposed on varying degrees of hepatic fibrosis related to Th deposition in 4 cases. (21.1%). (author)

    2009-01-01

    Objective: To explore and understand the CT findings of 5 rare histological variants of hepatocellular carcinoma. Methods: CT findings of 31 cases of rare histological variants confirmed by surgery and pathology were analyzed retrospectively. Results: 13 cases were clear cell hepatocellular carcinoma. 3 cases of them showed patchy fat density in plain scans. Enhanced CT showed features of 'fast in fast out' which was similar to the common hepatocellular carcinoma. 4 cases belonged to sclerosis hepatocellular carcinoma. They appeared as heterogeneous, slowly enhancement on arterial phase images, and delay enhancement on portal venous phase and delay phase images. 9 cases belonged to mixed hepatocellular carcinoma. 5 cases of them showed inhomogeneous enhancement and 4 without enhancement during arterial phase, 3 cases showed delay enhancement and 4 without during portal venous and delay phase. 3 cases were fibrolamellar hepatocellular carcinoma. All showed obvious and fastly enhancement on arterial phase images, subsided slowly on the portal venous and delay phase images, showing features of 'fast in slow out', no enhancement was seen in the central scar. Shrinkage phenomenon on the surface of liver could be seen on the CT plain scans in sclerosis, mixed and fibrolamellar hepatocellular carcinoma. 2 cases were the type of dense hepatocellular carcinoma. The surrounding part in the 2 cases were slightly enhanced, while the most part of the center were not enhanced similar to necrosis. Conclusion: The CT findings of rate histological variant of hepatocellular carcinoma are characteristic. Analyzing the CT plain and enhancement finding is helpful to the diagnosis of these types of hepatocellular carcinoma. (authors)

    A 60-year-old male patient who previously underwent transarterial chemoembolization for recurrent hepatocellular carcinoma three months ago presented to the emergency department with pleural effusion and hemoptysis. On serial review of plain radiographs and chest CT, transdiaphragmatic migration of Lipiodol from the treated area of the liver into the ipsilateral pleural cavity was demonstrated. The patient consequently developed empyema in the right thorax. Therefore, percutaneous drainage was performed. Empyema and pleural effusion regressed after 10 days of medical treatment and drainage. After that, the patient was transferred back to the local clinic upon full symptomatic recovery. Herein, we describe a rare complication of transarterial chemoembolization for hepatocellular carcinoma manifesting as an empyema secondary to the migration of the ethiodized oil content from the liver into the ipsilateral pleural cavity.

  5. Development of Hepatocellular Carcinoma Associated with Anabolic Androgenic Steroid Abuse in a Young Bodybuilder: A Case Report

    Aline Hardt

    2012-01-01

    Full Text Available Introduction. Many different etiological factors are involved in the development of hepatocellular carcinoma (HCC. We report the case of HCC in a 37-year-old male professional bodybuilder with extensive anabolic androgenic (AAS steroid abuse. Case Presentation. Because of increasing epigastric and abdominal pain, abdominal ultrasound was performed in a 37-year-old male professional bodybuilder. A hyperechoic lesion in the liver was detected in segment VI. The magnetic resonance imaging showed hepatomegaly and confirmed the lesion, which showed features of a hepatocellular adenoma (HCA. Laboratory values were inconspicuous. After laparoscopic segmentectomy the histological examination revealed HCC. Conclusion. While the development of HCA in the liver by chronic intake of AAS is well known, little is known about the association with HCC. The presented case may indicate aetiological association of chronic intake of AAS and the development of HCC.

    Based on 540 hepatocellular carcinoma patients and 540 age- and gender-matched controls, we tested the hypothesis that high mobility group protein box1 (HMGB1) and the receptor for advanced glycation end products (RAGE) genes are two potential candidate susceptibility genes for hepatocellular carcinoma in a multicenter hospital-based case-control analysis. The genotypes of seven widely-studied polymorphisms were determined, and their distributions respected the Hardy-Weinberg equilibrium. The mutant alleles of two polymorphisms, rs1045411 in HMGB1 gene and rs2070600 in RAGE gene, had significantly higher frequencies in patients than in controls (P hepatocellular carcinoma significantly, particularly for rs2070600 under the additive (odds ratio [OR] = 1.77; 95% confidence interval [CI]: 1.34-2.32; P hepatocellular carcinoma compared with the commonest C-C-T haplotype after adjustment. In RAGE gene, the T-T-A-G (rs1800625-rs1800624-rs2070600-rs184003) (adjusted OR; 95% CI; P: 1.75; 1.02-3.03; 0.045) and T-T-A-T (adjusted OR; 95% CI; P: 1.95; 1.01-3.76; 0.048) haplotypes were associated with a marginally increased risk of hepatocellular carcinoma compared with the commonest T-T-G-G haplotype. In summary, we identified two risk-associated polymorphisms (rs1045411 and rs2070600), and more importantly a joint impact of seven polymorphisms from the HMGB1/RAGE axis in susceptibility to hepatocellular carcinoma.

    2017-10-01

    Full Text Available Background/Objectives: Previous studies showed that zolpidem use could be associated with increased cancer risk, but the role of zolpidem on hepatocellular carcinoma (HCC risk remains undetermined. The study purpose was to examine the association between HCC risk and zolpidem use in Taiwan.Methods: Using the database from the Taiwan National Health Insurance Program, we designed a case-control study which consisted of 77986 subjects aged 20 years or older with newly diagnosed HCC as the case group, and 77986 subjects without HCC as the control group, from 2000 to 2011. Ever use of zolpidem was defined as a subject who had at least a prescription for zolpidem before the index date. Never use was defined as a subject who did not have a prescription for zolpidem before the index date. The association between HCC risk and zolpidem use was determined by the odds ratio (OR and 95% confidence interval (CI in a multivariable logistic regression model.Results: After adjustment for confounding factors, the adjusted OR of HCC was 1.05 (95% CI 0.97, 1.13 for subjects with ever use of zolpidem, compared with never use of zolpidem. The adjusted OR of HCC was 1.01 for subjects with increasing cumulative duration of zolpidem use for every 1 year (95% CI 0.99, 1.03, compared with never use of zolpidem.Conclusion: There is no significant association between HCC risk and zolpidem use. There is no duration-dependent effect of zolpidem use on HCC risk.

    2016-08-01

    This study aimed to evaluate the short- and long-term outcomes of hepatectomy for hepatocellular carcinoma (HCC) with bile duct tumor thrombus (BDTT), including cases with obstructive jaundice. The study reviewed 42 HCC patients with BDTT, including six patients who needed preoperative biliary drainage due to obstructive jaundice, and 732 HCC patients without BDTT. The authors analyzed the impact of BDTT on the surgical outcomes and assessed the outcomes of hepatectomy for patients presenting with obstructive jaundice. The HCC patients with BDTT, almost all with stage 3 or 4 disease, had increased alpha-fetoprotein expression, larger tumors, and more portal vein invasion status. The survival of the HCC patients with BDTT was significantly inferior to that of the patients without BDTT (p = 0.0003). Survival did not differ significantly between the HCC patients with BDTT and those without BDTT when the two groups were matched by stage (p = 0.3366). The HCC patients with BDTT who presented with obstructive jaundice demonstrated outcomes similar to those for the HCC patients with BDTT who did not present with obstructive jaundice in terms of the overall survival rate (p = 0.5469). The perioperative outcomes for the HCC patients with BDTT did not depend on the presence or absence of preoperative jaundice. No patients in either BDTT group demonstrated 90-day mortality in this study. Hepatectomy should be considered for HCC patients with BDTT, even for patients with obstructive jaundice, because the surgical outcomes equivalent to those for HCC without BDTT can be achieved.

    2012-02-01

    Full Text Available Abstract Background Orthotopic liver transplantation (OLT is one of the most effective treatments for patients with hepatocellular carcinoma (HCC within the Milan criteria. However, for patients beyond these criteria, the recurrence rate is higher and the prognosis is worse. Sorafenib is the only drug showing survival benefits in advanced HCC patients; however, its role in patients beyond the Milan criteria after OLT remains unclear and requires further investigation. Methods As a case-control study, we retrospectively analyzed 17 Chinese patients beyond Milan criteria undergoing OLT for HCC. These patients were stratified into adjuvant (n = 5, palliative (n = 6, and control groups (n = 6. Results Nine of 11 patients who received sorafenib after OLT needed dose reduction due to more than grade 2 side effects. The disease-free survival rates for patients with or without adjuvant sorafenib were 100% versus 37.5% (p = 0.034 at 6 months, 66.7% versus 9.4% (p = 0.026 at 12 months, and 66.7% versus 0.0% (p = 0.011 at 18 months, respectively. The overall survival rates for patients in palliative and control groups were 66.7% versus 40.0% (p = 0.248 at 6 months, 66.7% versus 40.0% (p = 0.248 at 12 months, and 50.0% versus 20.0% (p = 0.17 at 18 months, respectively. Patients in the adjuvant group had better overall survival rates than those in the palliative and control groups (p = 0.031 at 24-month follow-up. Conclusions Adjuvant sorafenib could possibly extend both disease-free and overall survival for HCC patients beyond Milan criteria after OLT.

  12. Hep par-1: a novel immunohistochemical marker for differentiating hepatocellular carcinoma from metastatic carcinoma

    Hanif, R.

    2014-01-01

    To evaluate the diagnostic utility of Hep par-1 in differentiating hepatocellular carcinoma from metastatic carcinoma taking histopathology as a gold standard. Study Design: Comparative cross-sectional study. Place and Duration of Study: Pathology Department, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from April 2007 to February 2008. Methodology: Hep par-1 immunohistochemical stain was performed on 60 cases of liver carcinoma, 30 cases each of metastatic and hepatocellular carcinoma. Information regarding patient age, gender, sign and symptoms, radiographic findings, histological grade of tumour, and expression of Hep par-1 on hepatocellular and metastatic carcinoma were recorded on proforma sheet. Sensitivity, specificity, positive and negative predictive values, and accuracy of Hep par-1 were calculated using the formulas. Results: Hep par-1 expression was noted in 25 out of 30 cases of hepatocellular carcinoma (83%). Out of 30 cases of metastatic carcinoma, only one case expressed staining in < 5% tumour cells and remaining 29 cases showed no reactivity. The age of the patients with hepatocellular carcinoma ranged from 40 to 76 years with a median age of 60.5 years and 40 - 75 years for metastatic carcinomas with a median age of 57.5 years. Conclusion: Hep par-1 is a reliable immunohistochemical marker for cases of hepatocellular carcinoma (HCC). It can be used along with other markers in morphologically difficult cases when differential diagnosis lies between poorly differentiated HCC and metastatic carcinoma of liver. (author)

    -absorbed dose to the various organs (including that to tumor) was calculated according to MIRD scheme using specially developed software by IAEA. From this value, the MTA of Re-188, which could be safely injected to the patient, was calculated and injected through hepatic artery after femoral catheterisation. Mean age, height and weight of the patients were 47.4+8.6 years, 165.8+9.3 cm and 58.4+10.7 Kg, respectively (M:F=9:1). Mean radiation absorbed dose was calculated to be 0.37+0.18, 0.045+0.05, 0.00017+0.00006 and 1.61+0.93 cGy/MBq to the normal liver parenchyma, lungs, bone marrow and tumor, respectively. The mean MTA was calculated to be 9432+3650 MBq, with the normal liver parenchyma being the critical organ in 74% cases. With administered MTA, 115+39 Gy of radiation dose could be delivered to the tumor, which was much more than the desired tumoricidal dose. All patients tolerated therapy very well. We conclude that with individual dosimetry, one can safely administer the maximum possible amount of Re-188 labeled lipiodol to the patients with hepatocellular carcinoma; delivering the tumoricidal radiation dose to the tumor without jeopardizing the other organs.

  14. [Metastasis of Hepatocellular Carcinoma to the Membrane of Chronic Subdural Hematomas:A Case Report].

    Oshita, Jumpei; Ohba, Shinji; Itou, Yoko; Yonezawa, Koki; Hosogai, Masahiro

    2017-10-01

    An 81-year-old man presented with gait disturbance. Two months previously, he suffered from hepatocellular carcinoma and transarterial chemoembolization was performed. A head computed tomography(CT)scan revealed bilateral chronic subdural hematomas. The patient's gait disturbance was improved after achievement of bilateral burr hole drainage. A head CT two months after treatment revealed no recurrence of the hematomas. However, head CT images obtained four months after treatment revealed an abnormal mass in the right parietal region attached to the internal surface of the skull. The mass was located in the same region from where the chronic subdural hematomas were previously removed via burr hole drainage, and was suspected to have originated from the dura mater. We performed craniotomy and total removal of the mass. The dura mater was intact, and macroscopically, the mass originated from the organized membrane of the chronic subdural hematoma. A pathological examination revealed metastasis of hepatocellular carcinoma to the membrane of the chronic subdural hematomas. Head magnetic resonance imaging(MRI)performed 39 days after craniotomy presented a new lesion in the left parietal region attached to the internal surface of the skull. The patient subsequently died 46 days post-operation. When examining chronic subdural hematomas in cancer patients, histological examination of the dura mater, hematoma, and membrane of the hematoma are important. The possibility of metastasis to the capsule of the hematoma should be considered.

    2011-01-01

    Full Text Available Hepatocellular carcinoma rarely metastasizes to the orbit. We report a 45-year-old male, HBV+, HIV+, with a past history of a liver transplant for ELSD (end-stage liver disease with hepatocellular carcinoma and recurrent HCC, who presented with proptosis and diplopia of the left eye. CT scans of the head revealed a large, irregular mass in the left orbit causing superior and lateral destruction of the orbital bone. Biopsy specimens of the orbital tumor showed features of metastatic foci of hepatocellular carcinoma. Only 16 other cases of HCC metastasis to the orbit have been described in literature, and this is the first case in a previously transplanted HIV+, HBV+ patient.

    Overexpression of Cullin7 is associated with some types of malignancies. However, the part of Cullin7 in hepatocellular carcinoma remains unclear. The aim of this study was to investigate the role of Cullin7 in pathogenesis and the progression of hepatocellular carcinoma. In the present study, the expression of Cullin7 in hepatocellular carcinoma cell lines and five surgical hepatocellular carcinoma specimens was detected with quantitative reverse transcription PCR and western blotting. In addition, the protein expression of Cullin7 was examined in 162 cases of archived hepatocellular carcinoma using immunohistochemistry. We found elevated expression of both mRNA and protein levels of Cullin7 in hepatocellular carcinoma cell lines, and Cullin7 protein was significantly upregulated in hepatocellular carcinoma compared with paired normal hepatic tissues. The immunohistochemistry analysis revealed that overexpression of Cullin7 occurred in 69.1% of hepatocellular carcinoma samples, which was a significantly higher rate than that in adjacent normal hepatic tissue (P hepatocellular carcinoma HepG2 cells, we revealed that Cullin7 could significantly enhance cell proliferation, growth, migration and invasion. Conversely, knocking down Cullin7 expression with short hairpin RNAi in hepatocellular carcinoma HepG2 cells inhibited cell proliferation, growth, migration and invasion. Our studies provide evidence that overexpression of Cullin7 plays an important role in the pathogenesis and progression of hepatocellular carcinoma and may be a valuable marker for hepatocellular carcinoma management.

    Epidemiology of hepatocellular carcinoma is changing worldwide. This study aimed at evaluating the changing scenario of aetiology, presentation, management and prognosis of hepatocellular carcinoma in Italy during the last 15 years. Retrospective analysis of the ITA.LI.CA (Italian Liver Cancer) database including 5192 hepatocellular carcinoma patients managed in 24 centres from 2000 to 2014. Patients were divided into three groups according to the date of cancer diagnosis (2000-2004, 2005-2009 and 2010-2014). The main results were as follows: (i) progressive patient aging; (ii) progressive expansion of non-viral cases and, namely, of "metabolic" hepatocellular carcinomas; (iii) increasing proportion of hepatocellular carcinoma diagnosed during a correct (semi-annual) surveillance programme; (iv) favourable cancer stage migration; (v) increased use of radiofrequency ablation to the detriment of percutaneous ethanol injection; (vi) improved outcomes of ablative and transarterial treatments; (vii) improved overall survival (adjusted for the lead time in surveyed patients), particularly after 2009, of both viral and non-viral patients presenting with an early- or intermediate-stage hepatocellular carcinoma. During the last 15 years several aetiological and clinical features of hepatocellular carcinoma patients have changed, as their management. The observed improvement of overall survival was owing both to the wider use of semi-annual surveillance, expanding the proportion of tumours that qualified for curative treatments, and to the improved outcome of loco-regional treatments. © 2016 John Wiley & Sons A/S.

  18. Treatment options for hepatocellular carcinoma.

    Sandhu, Dalbir S; Tharayil, Vivek S; Lai, Jin-Ping; Roberts, Lewis R

    2008-02-01

    Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

    Thirty cases of pathologically confirmed small hepatocellular carcinoma were examined by Incremental Dynamic CT (ICT). ICT scanned the whole liver with single-breath-hold technique; therefore, effective early contrast enhancement could be obtained for diagnosis. Among the 30 tumors, 26 were detected. The detection rate was 87%. A high detection rate was obtained in tumors more than 20 mm in diameter. Twenty-two of 26 tumors could be diagnosed correctly. ICT examination was useful for detection of small hepatocellular carcinoma. (author)

    Wilson disease is caused by the accumulation of copper in the liver, brain or other organs, due to the mutation in ATP7B gene, which encodes protein that helps in excretion of copper in the bile canaliculus. Clinical presentation varies from asymptomatic elevation of transaminases to cirrhosis with decompensation. Hepatocellular carcinoma is a known complication of cirrhosis, but a rare occurrence in Wilson disease. We present a case of neurological Wilson disease, who later developed decompensated cirrhosis and hepatocellular carcinoma.

    The "meeting-in-the-middle" (MITM) is a principle to identify exposure biomarkers that are also predictors of disease. The MITM statistical framework was applied in a nested case-control study of hepatocellular carcinoma (HCC) within EPIC where healthy lifestyle index (HLI) variables were related to

    Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and leading cause of death among patients with cirrhosis. Treatment guidelines are based according to the Barcelona Clinic Liver Cancer staging system. The choice among therapeutic options that include liver resection, liver transplantation, locoregional, and systemic treatments must be individualized for each patient. The aim of this paper is to review the outcomes that can be achieved in the treatment of HCC with the heterogeneous therapeutic options currently available in clinical practice. PMID:25132740

    2018-02-09

    Hepatocellular carcinoma is one of the main important causes of cancer-related death and its mortality is increasingly worldwide. In Europe, alcohol abuse accounts for approximately half of all liver cancer cases and it will become the leading cause of hepatocellular carcinoma in the next future with the sharp decline of chronic viral hepatitis. The pathophysiology of alcohol-induced carcinogenesis involves acetaldehyde catabolism, oxidative stress and chronic liver inflammation. Genetic background plays also a significant role and specific patterns of gene mutations in alcohol-related hepatocellular carcinoma have been characterized. Survival is higher in patients who undergo specific surveillance programmes than in patients who do not. However, patients with alcohol cirrhosis present a significantly greater risk of liver decompensation than those with cirrhosis due to other aetiologies. Furthermore, the adherence to screening program can be suboptimal. Liver transplant for patients with Milan-in hepatocellular carcinoma represents the best possible treatment in case of tumour recurrence/progression despite loco-regional or surgical treatments. Long-term result after liver transplantation for alcohol related liver disease is good. However, cardiovascular disease and de novo malignancies can significantly hamper patients' survival and should be carefully considered by transplant team. In this review, we have focused on the evolution of alcohol-related hepatocellular carcinoma epidemiology and risk factors as well as on liver transplantation in alcoholic patients with and without hepatocellular carcinoma.

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    2013-01-01

    Sorafenib, an oral multikinase inhibitor, is the only systemic agent proven to be effective in patients with hepatocellular carcinoma (HCC). There are no approved second line systemic therapies in patients who have had disease progression on or are not eligible to sorafenib. We describe two cases of unresectable HCC that were treated with low, "metronomic" doses of capecitabine. In the first patient, capecitabine was used after sorafenib failure. In the second case, treatment with capecitabine was attempted since the patient was considered not eligible for sorafenib due to spontaneous hepatic bleeding of a large HCC lesion. Treatment was effective and well tolerated in both patients with long-lasting objective responses. Lacking established second-line therapy, metronomic capecitabine may be a valid alternative in the treatment of HCC patients who are judged not eligible for sorafenib or those having progression disease on sorafenib.

    In order to detect and to evaluate the frequency, the distribution, and the radiological findings of skeletal metastases from hepatocellular carcinoma, the authors retrospectively analyzed radiographic, scintigraphic, and CT findings of 257 patients with hepatocellular carcinoma. The results were as follows: 1. Skeletal metastases were demonstrated in 21 patients (8.2%). 2. Frequent symptoms were pain, limitation of motion, paralysis, and mass. In nine of them the initial symptoms were due to skeletal metastases. 3. The common sites of metastases were spine (13 cases), ribs (8 cases), pelvis (8 cases) and femur (6 cases). Humerus, skull and sternum were also frequently involved. 4. Plain film findings were purely osteolytic in all cases and pathologic fractures were noted in 5 cases. 5. The lesions appear expansible in 7 cases, and 4 of them showed associated soft tissue masses on CT scans. 6. Bone scans were performed in 13 cases of them and showed increased radiotracer uptake in all. 7. Angiographic studies of 3 cases showed hypervascularity of the metastatic lesions as well as the primary hepatic tumor.

    Adenomas and hepato cellular carcinomas cannot be differentiated by nuclear medicine: both exhibit masked radiodrug trapping at reduced perfusion. Two patients revealed specific accumulation in extrahepatic foci unknown before; hence, the diagnosis of a metastasizing hepatocellular carcinoma had to be verified. One case is demonstrated in full detail. (orig./SHA).

    A 51-year-old male patient with hepatocellular carcinoma was treated preoperatively by fast neutron radiotherapy (910 rad/7 fractions/15 days) with a field of 8 x 6 cm. Radiation-associated liver function disturbance was scarcely observed. No side effect, such as loss of appetite and general fatigue, was encountered. According to the classification of Ohoshi and Shimosato, histological effect of radiation was graded as II sub(A). There is no preoperative fast neutron radiotherapy for hepatocellular carcinoma in Japan in the literature.

    2009-12-24

    967 patients with unresectable and untransplantable, biopsy-proven hepatocellular carcinoma (HCC) were prospectively evaluated at baseline and followed up till death. Survival was the end point. We found that male gender, ascites, cirrhosis, portal vein thrombosis (PVT), elevated AFP or bilirubin, or alkaline phosphatase, were each statistically significant adverse prognostic factors. Patients with normal AFP survived longer than those with elevated AFP, even in the presence of PVT, large or bilobar tumors or cirrhosis. We used a bivariate analysis to separate patient sub groups based on liver function and tumor characteristics and found clear discrimination in survival between subsets; in addition both cirrhosis and presence of PVT were significant factors. We also used a purely mathematical approach to derive subgroups and a prognostic model for individual patients. Interestingly, the two approaches gave similar predictive information, which opens the possibility of a more detailed mathematical analysis in the future. The results of this large dataset show that amongst non-surgical HCC patients, there are clear subsets with longer survival. The data supports the concept of heterogeneity of HCC. The three factors, bilirubin, AFP, and PVT predominate in prognosis.

    A total of 967 patients with unresectable and untransplantable, biopsy-proven hepatocellular carcinoma (HCC) were prospectively evaluated at baseline and followed up till death. Survival was the end-point for all analyses. We found in our overall analysis, that male gender, ascites, cirrhosis, portal vein thrombosis (PVT), elevated alpha-fetoprotein (AFP) or bilirubin or alkaline phosphatases were each statistically significant adverse prognostic factors. Patients with normal AFP survived longer than those with elevated AFP, in the presence of PVT, large or bilobar tumors or cirrhosis. We used a bivariate analysis to separate patient subgroups based on poor liver function and aggressive tumor characteristics. In subgroup analysis based on these subsets, there was clear discrimination in survival between subsets; in addition both cirrhosis and presence of PVT were significant, independent but modest risk factors. The results of this large dataset show that amongst nonsurgical HCC patients, there are clear subsets with longer survival than other subsets. This data also supports the concept of heterogeneity of HCC.

    1982-09-15

    It is well known that CT is very useful in the evaluation of hepatocellular carcinoma. The computed tomographic findings of 56 patients diagnosed as hepatocellular carcinoma were reviewed and analyzed. The results were as follows: 1. The male to female ratio was 3 : 1 and the age ranged from 31 to 73 years with average age of 54 years. 2. Alpha-fetoprotein was positive in 19 out of 38 cases (50%). HBsAg was positive in 8 out of 33 cases (24%). 3. All lesions were seen as areas of low density except 1 case (0%) of isodensity, and 40 cases (72%) appeared to be solitary while 15 (26%) were multifocal. The low density was homogenous in 13 cases (24%) and inhomogenous in 42 cases (76%), and 18 cases out of 42 cases inhomogenous low density showed peripheal and/or central nodular enhancement. The additional findings were contour changes in 37 cases (66%), metastasis in 35 cases (63%), splenomegaly in 23 cases (42%) and ascities in 22 cases (39%). 4. In postcontrast scans, 41 cases (80%) out of 51 cases showed the change of density after contrast infusion. The presence and extent of tumors were better seen after contrast infusion in 30 cases (59%), better seen before contrast infusion in 11 cases (21%) and no significant difference before and after contrast infusion in 10 cases (20%). 5. The sites of involved lobe were right lobe in 38 cases (68%), left lobe in 5 cases (9%) and both lobes in 13 cases (23%). 6. 35 cases (63%) showed evidence of metastasis to regional lymph nodes, organ or tissues.

    2014-04-15

    A 59-year-old man with a known central hepatocellular carcinoma (HCC) underwent a trans-arterial-chemo-embolization (TACE) and a post-TACE percutaneous radiofrequency ablation (PRFA). Two months after the PRFA, the patient presented jaundice and an abdominal computed tomography was obtained. An arterial enhancing mass adjacent to the ablated necrotic lesion with a continuously coexisting mass inside the right hepatic duct, suggestive of a HCC recurrence with a direct extension to the biliary tract was found. Finally a biliary tumor obstruction has been developed and a percutaneous transhepatic biliary drainage was performed. This case of biliary obstruction caused by directly invaded recurred HCC after PRFA will be reported because of its rare occurrence.

  14. Are metastases from metastases clinical relevant? Computer modelling of cancer spread in a case of hepatocellular carcinoma.

    Anja Bethge

    Full Text Available BACKGROUND: Metastasis formation remains an enigmatic process and one of the main questions recently asked is whether metastases are able to generate further metastases. Different models have been proposed to answer this question; however, their clinical significance remains unclear. Therefore a computer model was developed that permits comparison of the different models quantitatively with clinical data and that additionally predicts the outcome of treatment interventions. METHODS: The computer model is based on discrete events simulation approach. On the basis of a case from an untreated patient with hepatocellular carcinoma and its multiple metastases in the liver, it was evaluated whether metastases are able to metastasise and in particular if late disseminated tumour cells are still capable to form metastases. Additionally, the resection of the primary tumour was simulated. The simulation results were compared with clinical data. RESULTS: The simulation results reveal that the number of metastases varies significantly between scenarios where metastases metastasise and scenarios where they do not. In contrast, the total tumour mass is nearly unaffected by the two different modes of metastasis formation. Furthermore, the results provide evidence that metastasis formation is an early event and that late disseminated tumour cells are still capable of forming metastases. Simulations also allow estimating how the resection of the primary tumour delays the patient's death. CONCLUSION: The simulation results indicate that for this particular case of a hepatocellular carcinoma late metastases, i.e., metastases from metastases, are irrelevant in terms of total tumour mass. Hence metastases seeded from metastases are clinically irrelevant in our model system. Only the first metastases seeded from the primary tumour contribute significantly to the tumour burden and thus cause the patient's death.

  15. Clinical features of progressive vacuolar hepatopathy in Scottish Terriers with and without hepatocellular carcinoma: 114 cases (1980-2013).

    To characterize signalment, clinical features, clinicopathologic variables, hepatic ultrasonographic characteristics, endocrinologic profiles, treatment response, and age at death of Scottish Terriers with progressive vacuolar hepatopathy (VH) with or without hepatocellular carcinoma (HCC). Retrospective case series. 114 Scottish Terriers with progressive VH. Electronic databases from 1980 to 2013 were searched for adult (age > 1 year) Scottish Terriers with histopathologic diagnoses of diffuse glycogen-like VH. Available sections of liver specimens were histologically reevaluated to confirm diffuse VH with or without HCC; 8 dogs with HCC only had neoplastic tissue available. Physical examination, clinicopathologic, treatment, and survival data were obtained. 39 of 114 (34%) dogs with VH had HCC detected at surgery or necropsy or by abdominal ultrasonography. Histologic findings indicated that HCC was seemingly preceded by dysplastic hepatocellular foci. No significant differences were found in clinicopathologic variables or age at death between VH-affected dogs with or without HCC. Fifteen of 26 (58%) dogs with high hepatic copper concentrations had histologic features consistent with copper-associated hepatopathy. Although signs consistent with hyperadrenocorticism were observed in 40% (46/114) of dogs, definitive diagnosis was inconsistently confirmed. Assessment of adrenal sex hormone concentrations before and after ACTH administration identified high progesterone and androstenedione concentrations in 88% (22/25) and 80% (20/25) of tested dogs, respectively. Results suggested that VH in Scottish Terriers may be linked to adrenal steroidogenesis and a predisposition to HCC. In dogs with VH, frequent serum biochemical analysis and ultrasonographic surveillance for early tumor detection are recommended.

    1984-08-01

    Forty three cases of small hepatocellular carcinoma (measuring less than 3 cm in diameter on imaging modalities) were detected during a period of four years and two months. There were two cases in which hepatoma measured 1 cm in diameter, twenty four cases between 1 and 2 cm, and seventeen cases between 2 and 3 cm. The relative role of each modality and AFP value in the detection of these tumors was evaluated. The detection rate of small hepatocellular carcinoma by liver scintigraphy, ultrasonography (US), computed tomography (CT) and angiography was 8%, 74%, 70% and 95%, respectively. The sensitivity of serum AFP value was 67% (either measuring more than 200ng/ml or showing a tendency of steady rising even if below the level of 200ng/ml). Most hepatomas less than 2 cm in size were hypoechoic on US, and those above 2 cm in size were hyperechoic with peripheral sonolucency (halo). Almost all cases were described as low density area on both plain and enhancement CT. Angiography was the best method for detecting small hepatomas. It may be recommended to perform angiography on every patient with liver cirrhosis at the time of diagnosis of this disease. Periodic examinations by AFP, US and CT should be done if the angiography was negative. Evaluation by US in every three months and by CT in every twelve months may be appropriate.

    Recurrent gastrointestinal bleeding from hepatocellular carcinoma (HCC) invading the duodenum is very rare. We present a case of 50-year-old male who was admitted with a history of recurrent upper gastrointestinal tract (UGIT) bleeding, weight loss and anemia. The patient was known to have a chronic hepatitis C. Endoscopic examination showed grade-2 non-bleeding esophageal varices, and a large ulcerated duodenal mass partially obstructing the duodenal bulb outlet and causing recurrent UGIT bleeding. Pathological evaluation of the mass revealed HCC. (author)

  18. Methylation in hepatocellular carcinoma

    Regina M. Santella

    2007-02-01

    epigenetic aberrations as DNA isolated from an individual's tumor. The process by which tumor DNA is released into circulating blood is unclear but may result from accelerated necrosis, apoptosis or other processes. p53 mutation and p16 promoter hypermethylation have been detected in paired tumor and plasma of HCC cases. More recently, we investigated promoter hypermethylation in DNA isolated from the serum of HCC patients who provided repeated blood samples prior to diagnosis and controls enrolled in a cancer screen program in Taiwan. Among cases, aberrant methylation was found in serum DNA one to nine years before clinical HCC diagnosis. RASSF1A had the highest frequency of hypermethylation with 70% of cases having at least one positive sample compared to 44% for p16 and 22% for p15. For the controls, promoter hypermethylation was found in 6 and 4% of subjects for RASSF1A and p16, respectively; none had methylation of p15. An ROC curve that included clinical risk factors (age, HBsAg status, anti-HCV status, smoking, alcohol status and hypermethylation biomarkers gave an overall predictive accuracy of 89% with sensitivity and specificity 84% and 94%, respectively. The analysis of epigenetic changes on RASSF1A, p16 and p15 tumor suppressor genes in serum DNA may be a valuable biomarkers for early detection in populations at high risk of HCC. In addition, the area of global hypomethylation remains largely unexplored in HCC.

  19. Long-term survival after liver transplant for recurrent hepatocellular carcinoma with bile duct tumor thrombus: case report.

    Liu, Chao; Wang, Jie

    2012-12-01

    Hepatocellular carcinoma with bile duct tumor thrombus is considered an aggressive malignancy, and the prognosis of liver transplant for it remains obscure. A 42-year-old man with recurrent hepatocellular carcinoma and a history of surgical resection was admitted to our hospital with a 10-day history of yellowish urine and itchy skin. There were 3 lesions in the right lobe with the diameter of 2 cm each. A mass was found in the upper part of common bile duct, and the intrahepatic bile duct was dilated. His serum alpha-fetoprotein level was 2476 μg/L, total bilirubin level was 327 μmol/L, direct bilirubin level was 261 μmol/L, and alanine aminotransferase was 714 U/L. There was no main portal vein thrombus or extrahepatic metastases. Because of his poor liver function, he was listed for a liver transplant. During the wait (30 d), he underwent 9 episodes of plasmapheresis to decrease the serum level of bilirubin. He had an orthotopic liver transplant with the graft from a deceased donor. After the liver transplant, he received 5 cycles of chemotherapy with the regimen of oxaliplatin and 5-fluorouracil. This patient has survived without recurrence of hepatocellular carcinoma for more than 82 months and remains in good condition. Liver transplant may have a favorable result for hepatocellular carcinoma patient with a bile duct tumor thrombus, within the Milan criteria.

  20. Tumor vessels and contrast enhancement of hepatocellular carcinoma demonstrated by percutaneous transhepatic portography. Report of a case

    Fujisawa, I.; Minami, S.; Tsutsui, K.; Imura, T.; Asano, M.; Kitamura, O.; Matsumoto, M.; Ozawa, K.; Torizuka, K.

    A patient with an Edmondson type I-II hepatocellular carcinoma had, at celiac angiography, a poor arterial supply but a rich portal supply as observed at percutaneous transhepatic portography, an observation not previously reported in this disease. The importance of demonstrating the vascular supply of the tumor previous to planned intravascular treatment is obvious.

    2015-01-01

    AIM: To investigate whether the use of synchronous hepatectomy and splenectomy (HS) is more effective than hepatectomy alone (HA) for patients with hepatocellular carcinoma (HCC) and hypersplenism. METHODS: From January 2007 to March 2013, 84 consecutive patients with HCC and hypersplenism who underwent synchronous hepatectomy and splenectomy in our center were compared with 84 well-matched patients from a pool of 268 patients who underwent hepatectomy alone. The short-term and long-term outcomes of the two groups were analyzed and compared. RESULTS: The mean time to recurrence was 21.11 ± 12.04 mo in the HS group and 11.23 ± 8.73 mo in the HA group, and these values were significantly different (P = 0.001). The 1-, 3-, 5-, and 7-year disease-free survival rates for the patients in the HS group and the HA group were 86.7%, 70.9%, 52.7%, and 45.9% and 88.1%, 59.4%, 43.3%, and 39.5%, respectively (P = 0.008). Platelet and white blood cell counts in the HS group were significantly increased compared with the HA group one day, one week, one month and one year postoperatively (P Splenectomy and micro-vascular invasion were significant independent prognostic factors for disease-free survival. Gender, tumor number, and recurrence were independent prognostic factors for overall survival. CONCLUSION: Synchronous hepatectomy and hepatectomy potentially improves disease-free survival rates and alleviates hypersplenism without increasing the surgical risks for patients with HCC and hypersplenism.

  2. Percutaneous cryoablation for hepatocellular carcinoma

    Kyoung Doo Song

    2016-12-01

    Full Text Available Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC. Although radiofrequency (RF ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications. Cryoablation has several advantages over RF ablation such as well visualization of iceball, no causation of severe pain, and lack of severe damage to great vessels and gallbladder. It is important to know the advantages and disadvantages of cryoablation compared with RF ablation for improvement of therapeutic efficacy and safety.

  3. Medical treatment of hepatocellular carcinoma.

    Granito, Alessandro; Bolondi, Luigi

    2009-12-16

    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

  4. [Radiofrequency ablation of hepatocellular carcinoma].

    Widmann, Gerlig; Schullian, Peter; Bale, Reto

    2013-03-01

    Percutaneous radiofrequency ablation (RFA) is well established in the treatment of hepatocellular carcinoma (HCC). Due to its curative potential, it is the method of choice for non resectable BCLC (Barcelona Liver Clinic) 0 and A. RFA challenges surgical resection for small HCC and is the method of choice in bridging for transplantation and recurrence after resection or transplantation. The technical feasibility of RFA depends on the size and location of the HCC and the availability of ablation techniques (one needle techniques, multi-needle techniques). More recently, stereotactic multi-needle techniques with 3D trajectory planning and guided needle placement substantially improve the spectrum of treatable lesions including large volume tumors. Treatment success depends on the realization of ablations with large intentional margins of tumor free tissue (A0 ablation in analogy to R0 resection), which has to be documented by fusion of post- with pre-ablation images, and confirmed during follow-up imaging.

  5. Hepatoid adenocarcinoma of the stomach: an unusual case of elevated alpha-fetoprotein with prior treatment for hepatocellular carcinoma

    Joon Seong Ahn

    2013-06-01

    Full Text Available Hepatoid adenocarcinoma (HAC is a rare type of extrahepatic carcinoma whose morphology is similar to that of hepatocellular carcinoma (HCC. Metachronous HCC and HAC in the same patient is extremely rare. The case of a 68-year-old man with chronic hepatitis B infection who had both HCC and HAC of the stomach is reported herein. Nine years previously this patient had been diagnosed with HCC and received a right lobectomy. HCC that recurred at the caudate lobe at 6 months after the operation was successfully treated with transarterial chemoembolization. The patient was followed up regularly thereafter without evidence of tumor recurrence for 9 years. In July 2010 his serum alpha-fetoprotein (AFP level elevated from 6.5 ng/mL to 625.4 ng/mL, and he developed a probable single metastatic lymph node around the hepatic artery without intrahepatic lesions. Subsequent evaluation with upper endoscopy revealed a 4-cm ulcerative lesion on the antrum of the stomach. Subtotal gastrectomy was performed with lymph-node dissection. Histologic examination revealed a special type of extrahepatic AFP-producing adenocarcinoma-HAC with lymph-node metastasis-which indicates that HAC can be a cause of elevated AFP even in patients with HCC. HAC should be considered if a patient with stable HCC exhibits unusual elevation of AFP.

  6. A case-control study on the association of hepatitis B virus infection and hepatocellular carcinoma in Northeast Brazil

    Cotrim Helma

    1992-01-01

    Full Text Available Hepatitis B virus (HBV serological markers were investigated in 40 incident cases of hepatocellular carcinoma (HCC and in two age and sex matched control groups, comprising 40 patients with other cancers and 80 healthy individuals, resident in Bahia, Brazil. Serologic tests were done by radioimmunoassay. The study observed high proportion of seropositivity to HBsAg (42.5% and of those presenting HBsAg or antiHBc (65.0% among HCC cases, higher in men than women and in those aged 17 to 30 years old. HBsAg seropositivity among HCC patients was greater than in the control group with other cancers (7.5% and in healthy controls (2.5%, corresponding to odds ratio estimates of 15.0 (95% CI 3.29, 68.30 and 33.0 (95% CI 9.13, 119.28, both statistically significant. HBeAg was not observed and antiHBe was present in 41.2% of cases, suggesting the absence of viral replication, possibly with viral DNA intergration into the hepatocyte genome. The presence of cirrhosis was associated with HBsAg seropositivity among HCC cases. A history of chronic alcoholism is shown to be more frequently related to those cases with cirrhosis. This study highlights the relevant association between HCC and HBV in Northeast Brazil, particularly for young individuals, and the high risk of development of HCC for HBsAg carriers.

    Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma. Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses. In order to identify potential subtypes, two pathologists independently screened a cohort of 219 unselected hepatocellular carcinoma resection specimens and divided cases into potential subtypes. One of these promising candidate subtypes was further evaluated using histological and molecular techniques. This subtype was characterized by a unique and consistent set of histological features: smooth chromophobic cytoplasm, abrupt focal nuclear anaplasia (small clusters of tumor cells with marked nuclear anaplasia in a background of tumor cells with bland nuclear cytology), and scattered microscopic pseudocysts--we designate this variant as 'chromophobe hepatocellular carcinoma with abrupt anaplasia'. Thirteen cases were identified (6% of all hepatocellular carcinomas), including 6 men and 7 women with an average age of 61 years. Six cases occurred in cirrhotic livers. Serum AFP was elevated in 6 out of 10 cases. There were a variety of underlying liver diseases, but cases were enrichment for chronic hepatitis B, P=0.006. Interestingly, at the molecular level, this variant was strongly associated with the alternative lengthening of telomere (ALT) phenotype by telomere FISH. ALT is a telomerase-independent mechanism of telomere maintenance and is found in approximately 8% of unselected hepatocellular carcinomas. In contrast, 11/12 (92%) of the cases of chromophobe hepatocellular carcinoma with abrupt anaplasia were ALT-positive. In summary, we propose that chromophobe hepatocellular carcinoma with abrupt anaplasia represents a new subtype of

  8. Evaluation of transcatheter therapy for hepatocellular carcinoma

    Yamada, Toshihiko

    1990-01-01

    The author proposed improvement of the criteria for the effects of transcatheter therapy for hepatocellular carcinoma. 104 patients were treated by transcatheter therapy. Their responses were determined by the usual criteria. Next, they were classified and evaluated in 3 groups, with the area of lipiodol deposition on CT for over 4 weeks regarded as nacrosis. The result was determined, and its relationship to prognosis was studied in light of the repeated therapy. By the usual criteria, only 10% of patients were judged as PR, and there were no differences between therapies. Many of the NC cases had low AFP levels with therapy. At the initial therapy, the ratio of cases with low AFP levels was higher and the survival time was longer in the A group. So the A group was judged as most effective. Clinically, 10 patients were considered most benefitted by therapy. They were considered the A group, but all were judged as NC. Considering the effects of repeated therapy, 10 patients with NC were judged as the A-max group. Prognosis was poor in patients of the B-max and C-max groups. These results indicate that judgement by the usual criteria was inconsistent with clinical condition. It was improved by regarding the area of lipiodol deposition on CT for over 4 weeks as necrosis. Estimations of effects and prognosis were made more accurate by considering repeated therapy. Thus, the proposed improvement of the criteria by CT is more useful to estimate transcatheter therapy of the hepatocellular carcinoma. (author)

    Background: The objective of this study is to assess the outcome of the patients treated for hepatocellular carcinoma (HCC) in a General Surgery and Liver Transplantation Center. Methods: This retrospective study includes 844 patients diagnosed with HCC and surgically treated with curative intent methods. Curative intent treatment is mainly based on surgery, consisting of liver resection (LR), liver transplantation (LT). Tumor ablation could become the choice of treatment in HCC cases not manageable for surgery (LT or LR). 518 patients underwent LR, 162 patients benefited from LT and in 164 patients radiofrequency ablation (RFA) was performed. 615 patients (73%) presented liver cirrhosis. Results: Mordidity rates of patient treated for HCC was 30% and mortality was 4,3% for the entire study population. Five year overall survival rate was 39 % with statistically significant differences between transplanted, resected, or ablated patients (p 0.05) with better results in case of LT followed by LR and RFA. Conclusions: In HCC patients without liver cirrhosis, liver resection is the treatment of choice. For early HCC occurred on cirrhosis, LT offers the best outcome in terms of overall and disease free survival. RFA colud be a curative method for HCC patients not amenable for LT of LR. Celsius.

  11. Tumor Molecular Profiling for an Individualized Approach to the Treatment of Hepatocellular Carcinoma: A Patient Case Study

    2018-04-01

    Full Text Available Hepatocellular carcinoma (HCC is increasing in incidence, and the associated mortality rate remains among the highest. For advanced HCC, sorafenib has been shown to slightly prolong survival, and regorafenib and nivolumab, both recently approved by the United States Food and Drug Administration (FDA, may produce clinical benefits to a limited extent. Systemic chemotherapy has been shown to produce a modest response, but there is no clinically valid biomarker that can be used to predict which patients may benefit. In this case study, we present two patients with metastatic HCC, they received systemic treatment using capecitabine, oxaliplatin, and either bevacizumab or sorafenib. The tumor response to treatment was determined by the progression-free survival (PFS. Molecular profiling of the tumors showed differential expression of biochemical markers and different mutational status of the TP53 and β-catenin (CTNNB1 genes. We hypothesize that the PFS correlates with the tumor molecular profiles, which may be predictive of the therapeutic response to systemic chemotherapy. Further investigation is indicated to correlate tumor biomarkers and treatment responses, with the objective of personalizing the therapies for patients with advanced HCC.

    Candace Wu

    2017-01-01

    Full Text Available Background. Sorafenib, an oral tyrosine kinase inhibitor (TKI, targets multiple tyrosine kinase receptors (TKRs involved in angiogenesis and tumor growth. Studies suggest that inhibition of TKR impacts cardiomyocyte survival. Inhibition of VEGF signaling interrupts angiogenesis and is associated with the development of hypertension and compensatory hypertrophy. Compensated hypertrophy ultimately leads to heart failure. Case Description. A 76-year-old man with a past medical history of systolic heart failure due to ischemic cardiomyopathy and stage IIIC hepatocellular carcinoma (HCC presented with symptoms of decompensated heart failure. Four months prior to admission, he was started on sorafenib. Results. Our patient was treated with intravenous furosemide and guideline directed therapy. Clinical status was complicated by the development of low cardiac output and shock requiring inotropic support. Careful titration of heart failure medication led to hemodynamic improvement and discontinuation of dobutamine. Conclusion. Greater awareness of sorafenib cardiotoxicity is essential. As TKI usage grows for treatment of cancers, heart failure-related complications will increase. In our patient, routine heart failure management and cessation of sorafenib led to clinical improvement. Future studies on the treatment of sorafenib cardiotoxicity should be explored further in this unique patient population.

  13. One stage resection of spontaneous rupture of hepatocellular carcinoma in the triangular ligament with diaphragm invasion: case report and review of the literature

    2012-09-01

    Full Text Available Abstract A spontaneous rupture of hepatocellular carcinoma (HCC can lead to extensive hemorrhage and is a rare but life-threatening event. A 58-year-old male patient with no history of trauma presented at our institution with severe epigastric pain and abdominal distension for 6 h. His blood pressure was a 60/40 mmHg, and pulse rate was 132/min. Abdominal contrast enhanced computed tomography (CT imaging revealed a ruptured mass under the left diaphragm and fluid collection in the upper abdomen, flanks and pelvic cavity. Exploratory laparotomy confirmed the presence of an active bleeding tumor in the triangular ligament invading into the diaphragm. The tumor was resected with an appropriate diaphragm margin. The resected tumor was 5 cm in diameter and pathologically identified as hepatocellular carcinoma with a negative surgical margin. This case report shows that ruptured hepatocellular carcinoma should be considered in the differential diagnosis of non-traumatic hemoperitoneum. And it is necessary to set a surgical plan for unpredictable HCC rupture with direct diaphragm invasion.

    With the rising incidence of chronic liver disease caused by viral hepatitis, hepatocellular carcinoma is showing a corresponding rise worldwide. Surgery remains the mainstay of treatment, but patients unfit for surgery or liver transplantation form the bulk of those presenting with this disease. Palliative treatments are being used to treat those and radiological modalities form the mainstay of the treatment. Radiology plays a major role in the diagnosis, treatment and follow-up of hepatocellular carcinoma. Current radiological treatment modalities include percutaneous ethanol ablation, radiofrequency ablation and trans-arterial chemoembolization. This update highlights the recent advancements in the field and compares their relative merits and demerits. (author)

    2011-01-01

    Full Text Available Background: Hepatocellular carcinoma (HCC is notorious for poor prognosis with limited therapeutic options. A better understanding of the role of regulatory T-cells (Tregs in HCC is important for design of immunotherapy based clinical protocol. The objective of the present study was to evaluate the presence of Tregs in tumor microenvironment in patients with HCC compared to chronic hepatitis (CH. Materials and Methods: The frequency of CD4 + CD25 + Treg cells was evaluated from peripheral blood (PB of 28 patients of HCC and 30 controls including CH cases and healthy donors using flowcytometry. Intratumoral Treg were also analyzed in tissue samples from 17 HCC cases and 15 CH cases. In addition the expression of FOXP3 and CTLA-4 was also studied by RT-PCR. Results: Frequency of CD4 + CD25 + cells in the PBMCs of HCC cases was significantly higher than in HC (10.8 ± 7.64 vs 3.05 ± 1.30, P < 0.005 and CH patients (2.88 ± 1.92, P < 0.005. Also Treg population was significantly higher in HCC tumor microenvironment compared to CH biopsies (15.8 ± 5.32 vs 5.51 ± 3.40, P < 0.05. Expression of FOXP3 and CTLA-4 was also significantly higher in HCC patients ( P < 0.05 compared to CH group. Conclusions: We provide evidence of an increased population of Treg not only in the PB but also in tumor microenvironment of HCC patients, suggesting association of enhanced Treg activity with poor immune responses to tumor antigens. These findings may in future play a significant role in designing immunotherapeutic approaches in HCC.

    Relationship on new statin use and the risk of hepatocellular carcinoma (HCC) in patients with incident type 2 diabetes mellitus (T2DM), who might be at the risk of developing HCC, is uncertained. A nationwide population-based nested case-control study was conducted within the National Health Insurance Service National Sample Cohort 2002-2013 in Korea. Newly prescribed statin after newly diagnosed T2DM was defined as statin use. Controls were matched to case patients on age, sex, follow-up time, and the date of diabetes diagnosis at a five-to-one ratio. Odds ratios (ORs) for associations of statin use with HCC were calculated using conditional logistic regression. After at least a 5-year HCC-free period, there were 229 incident HCC cases and 1,145 matched controls from 47,738 patients with incident diabetes. Of these 229 incident HCC cases, 27 (11.8%) were statin users, whereas 378 (33.0%) were statin users among 1,145 controls. Statin use was associated with a reduced risk of HCC development (adjusted OR [AOR]= 0.36, 95% confidence interval [CI] 0.22-0.60) after adjustment for chronic viral hepatitis, liver cirrhosis, alcoholic liver disease, previous cancer, aspirin use, insulin use, sulfonylurea use, metformin use, thiazolidinedione use, history of chronic obstructive pulmonary disease, Charlson comorbidity score, household income level, and residential area. Risk reduction was accentuated with an increase of cumulative defined daily doses (cDDD) compared with non-users (AORs 0.53, 0.36, 0.32, and 0.26 in ≤60, 60-180, 181-365, and >365cDDD, respectively; P for trend statin use before HCC diagnosis may have a beneficial inhibitory effect on HCC development in a dose-dependent manner, especially in individuals with liver disease. © 2016 UICC.

  17. Surgical Treatment of Hepatocellular Carcinoma

    Zamora-Valdes, Daniel; Taner, Timucin; Nagorney, David M.

    2017-01-01

    Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. In select patients, surgical treatment in the form of either resection or transplantation offers a curative option. The aims of this review are to (1) review the current American Association for the Study of Liver Diseases/European Association for the Study of the Liver guidelines on the surgical management of HCC and (2) review the proposed changes to these guidelines and analyze the strength of evidence underlying these proposals. Three authors identified the most relevant publications in the literature on liver resection and transplantation for HCC and analyzed the strength of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification. In the United States, the liver allocation system provides priority for liver transplantation to patients with HCC within the Milan criteria. Current evidence suggests that liver transplantation may also be indicated in certain patient groups beyond Milan criteria, such as pediatric patients with large tumor burden or adult patients who are successfully downstaged. Patients with no underlying liver disease may also benefit from liver transplantation if the HCC is unresectable. In patients with no or minimal (compensated) liver disease and solitary HCC ≥2 cm, liver resection is warranted. If liver transplantation is not available or contraindicated, liver resection can be offered to patients with multinodular HCC, provided that the underlying liver disease is not decompensated. Many patients may benefit from surgical strategies adapted to local resources and policies (hepatitis B prevalence, organ availability, etc). Although current low-quality evidence shows better overall survival with aggressive surgical strategies, this approach is limited to select patients. Larger and well-designed prospective studies are needed to better define the benefits and limits of such approach. PMID:28975836

    To describe the clinico-pathological and radiological profile of hepatocellular carcinoma. All consecutive patients suspected of having hepatocellular carcinoma (HCC), were admitted and included in this study. Diagnosis of HCC was established by clinical, biochemical, ultrasonographic and histopathologic findings. Patients with primary carcinoma elsewhere in the body, metastatic in the liver, fibrolamellar carcinoma and benign tumours were excluded from the study. At ultrasonography, the details of tumour size and number, portal vein thrombosis and presence of ascites were recorded. Patients were staged according to Okuda staging system. Results were described in mean and percentage values. There were 82 patients with hepatocellular carcinoma including 58 males and 24 females, with male to female ratio of 2.8:1. The mean age of patients was 56.24 +- 13.65 years. Right hypochondrial pain was the main symptom in 52 (63.4%) patients. The duration of symptoms varied from 1 month to 2 years. Tumour size was larger than 50% of liver size in 42 (51.2%) with portal vein thrombosis in 10 (12.19%). Anti HCV was positive in 44 (53.7%), HBsAg in 26 (31.7%) and both were found positive in 2 (2.44%) patients. Ten patients (12.2/%) found negative both for anti-HCV and HBsAg. According to Okuda staging system 18 patients had stage 1, 50 had stage 2 and 14 had stage 3 hepatocellular carcinoma. The mean age of presentation of hepatocellular carcinoma was younger as compared to western countries with potentially large non-resectable lesions. Chronic hepatitis C and B was found to be the major known factors. Patients with chronic hepatitis C and B should undergo vigorous HCC surveillance to detect early, potentially respectable HCC.

    Hepatocellular carcinoma is a very common neoplastic disease in countries where hepatitis viruses B and/or C are prevalent. Small hepatocellular carcinoma lesions detected by ultrasonography at an early stage are often hyperechoic because they are composed of well-differentiated cancer cells that are rich in triglyceride droplets. The triglyceride content of hepatocytes depends in part on the rate of lipogenesis. Key lipogenic enzymes, such as fatty acid synthase, are co-ordinately regulated at the transcriptional level. We therefore examined the mRNA expression of lipogenic enzymes in human hepatocellular carcinoma samples from 10 patients who had undergone surgical resection. All of the samples exhibited marked elevation of expression of mRNA for lipogenic enzymes, such as fatty acid synthase, acetyl-CoA carboxylase and ATP citrate lyase, compared with surrounding non-cancerous liver tissue. In contrast, the changes in mRNA expression of SREBP-1, a transcription factor that regulates a battery of lipogenic enzymes, did not show a consistent trend. In some cases where SREBP-1 was elevated, the main contributing isoform was SREBP-1c rather than SREBP-1a. Thus, lipogenic enzymes are markedly induced in hepatocellular carcinomas, and in some cases SREBP-1c is involved in this activation.

    1989-01-01

    To determine the optimal pulse sequence for detection and differential diagnosis of small hepatocellular carcinomas and cavernous hemangiomas less than 5 cm in diameter, the authors have analyzed spin-echo (SE) images of 15 small hepatocellular carcinomas and 31 small cavernous hemangiomas obtained at 2.0 T. Pulse sequences used included repetition times (TRs) of 500 and 2,000 msec and echo times (TEs) of 30,60,90,120,150, and 180 msec. Mean tumor-liver contrast-to-noise ratios on the SE 2,000/60 (TR msec/TE msec) sequence were 23.90 ± 16.33 and 62.10 ± 25.94 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences. Mean tumor-liver signal intensity ratios on the SE 2,000/150 sequence were 2.34 ± 1.72 and 6.04 ± 2.72 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences in hemangiomas

    The aim of this study was to determine the airway exposure of sugar and papermaking factory workers to aflatoxin B1 (AFB1) and to explore the potential association between AFB1 airway exposure and the risk of hepatocellular carcinoma (HCC) in a case-control study. Dust samples were collected from the sugarcane bagasse warehouse, and presser and paper production workshops. Blood samples were collected from 181 workshop employees and 203 controls who worked outside the workshop. AFB1 albumin adducts were detected using a double antibody sandwich enzyme-linked immunosorbent assay (ELISA). To explore the association between AFB1 airway exposure and the risk of HCC, the medical records of 68 HCC patients who worked in a sugar and papermaking factory between January 1994 and December 2013 were analyzed. A questionnaire was used to collect information from 150 healthy controls who worked for the same company and lived near the factory. AFB1 was detected in the dust samples, but could not be detected in any of the rice samples. An analysis of serum samples revealed serum AFB1 albumin adducts in 102 (56.35 %) of the study participants. However, in the control group, only 12 (5.9 %) individuals had detectable levels of AFB1 albumin adducts. Those with airway exposure to Aspergillus flavus-contaminated dust had an elevated risk of HCC compared to those without exposure (odds ratio, 5.24; 95 % confidence interval, 2.77-9.88; P = 0.00). The findings of this study indicate that occupational AFB1 airway exposure might be associated with the risk of AFB1-related HCC among the population that was used in this study. Intervention programs aimed at reducing exposure to inhalational AFB1 are needed urgently. Additional suitably designed, multicenter, prospective studies using large samples are needed to further confirm the results.

    Preoperative prediction of both microinvasive hepatocellular carcinoma and histological grade of hepatocellular carcinoma is pivotal to treatment planning and prognostication. The aim of this study was to evaluate whether some intraoperative ultrasound features correlate with both the presence of same histological patterns and differentiation grade of hepatocellular carcinoma on the histological features of the primary resected tumour. All patients with single, small hepatocellular carcinoma that underwent hepatic resection were included in this prospective double-blind study: the intraoperative ultrasound patterns of nodule were registered and compared with similar histological features. A total of 179 patients were enclosed in this study: 97 (54%) patients (34% in HCC ≤2 cm) had a microinvasive hepatocellular carcinoma at ultrasound examination, while 82 (46%) patients (41% in HCC ≤2 cm) at histological evaluation. Statistical analysis showed that diameters ≤2 cm, presence of satellites and microinvasive hepatocellular carcinoma at ultrasound examination were the variables with the strongest association with the histological findings. In the multivariate analysis, the vascular microinfiltration and infiltrative hepatocellular carcinoma aspect were independent predictors for grading. In patients with cirrhosis and hepatocellular carcinoma, the prevalence of microinvasive hepatocellular carcinoma is high, even in cases of HCC ≤2 cm. Intraoperative ultrasound findings strongly correlated with histopathological criteria in detecting microinvasive patterns and are useful to predict neoplastic differentiation. The knowledge of these features prior to treatment are highly desired (this can be obtained by an intraoperative ultrasound examination), as they could help in providing optimal management of patients with hepatocellular carcinoma. © 2017 John Wiley & Sons A/S.

    CT scans of 164 patients with hepatocellular carcinoma were studied, and abdominal lymph node metastases were detected in 13 cases. Most of these lymph node metastases occured in periportal, peripancreatic and paraaortic lymph nodes. Ten instances of each these metastases were identified by CT. Six of the patients had metastases in all three sites. In 9 of 13 cases, lymph node metastases were demonstrated by angiography and various degrees of contrast material stain were seen. Lymph node metastasis of hepatocellular carcinoma is apt to be hypervascular. Most of hepatocellular carcinoma with lymph node metastasis showed infiltrative growth, and tumor thrombosis in the portal vein was commonly complicated.

    Hepatocellular carcinoma is the most common primary tumor of the liver. Spreading outside the liver usually takes place in advanced stages of the disease, and bone is the third most common site of metastases. We present a case of hepatocellular carcinoma in which the first clinical manifestation was a single metastasis to the carpal bones. The interest of this case lies in the way this hepatocellular carcinoma manifested as well as in the unusual site of the metastasis. Copyright © 2012 SERAM. Published by Elsevier Espana.

    2016-01-01

    Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn's disease. The patient is a 61-year-old with longstanding Crohn's disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma.

    Full Text Available Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn’s disease. The patient is a 61-year-old with longstanding Crohn’s disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma. The patient underwent a hepatic resection, and there is no evidence of recurrence at the 11-month follow-up.

    Fibrolamellar hepatocellular carcinoma is an uncommon malignant tumor with characteristic clinical, radiological and histopahtological features that is usually associated with a more favorable natural course and greater survival than more common variants of hepatocellular carcinoma. We describe an atypical case of a fibrolamellar hepatocellular carcinomas sowing aggressive behaviour in a 20-year-old woman. The lesion presented with massive ascites, and imaging studies revealed extensive peritoneal metastatic spread. (Author) 8 refs.

  14. Treatment of Recurrent Hepatocellular Carcinoma with Sorafenib in a HIV/HCV Co-Infected patient in HAART: A Case Report

    2012-06-01

    Full Text Available Abstract Background Liver disease is the second cause of death among HIV patients receiving highly active antiretroviral therapy (HAART in Europe. HIV patients have a high prevalence of chronic HBV (6–10% and HCV (33% co-infection, and accelerated progression of viral hepatitis. Furthermore, the long duration of both HIV and HCV diseases in the HAART era increases the risk of hepatocellular carcinoma. Findings We report the case of a 49 year -old HIV/HCV co-infected male patient who developed hepatocellular carcinoma. The patient underwent a partial hepatectomy, and a few months later was treated with transcatheter arterial chemoembolisation due to hepatocarcinoma recurrence. Two months later, advanced hepatocellular carcinoma was diagnosed and sorafenib therapy was initiated. The patient achieved partial response of the main lesions, complete regression of the smallest lesions and did not experience clinical progression during the 20-month follow-up period. During therapy with sorafenib, the patient was treated with HAART with good viral and immunological responses. We used the therapeutic drug monitoring to assess antiretroviral concentrations during co-administration of sorafenib. Fosamprenavir Ctrough was found under the minimum level recommended by international guidelines. No grade 3 or 4 toxicities were observed. At month 20 of treatment, new liver lesions with portal vein thrombosis were diagnosed. After 28 months of sorafenib therapy, the patient deceased for severe liver insufficiency. Conclusions Sorafenib monotherapy demonstrated a marked delay in HCC disease progression in an HIV/HCV co-infected patient. Fosamprenavir Ctrough was found under the minimum level recommended by international guidelines, suggesting a possible interaction.

    Conclusions: The incidence of patients with massive bleeding due to gastric invasion of HCC is low, and only a few cases have been reported in the literature. Our purpose while presenting this rare case is to increase the awareness about the issue.

  16. Research progress of vascular change after TACE in hepatocellular carcinoma

    Kang Zhen; Xiao Enhua

    2013-01-01

    Mortality rate of hepatocellular carcinoma is high. The majority of the patients are diagnosed in advanced stage and lose surgical opportunities. Many studies have reported transcatheter arterial chemoembolization (TACE) is an effective treatment for unresectable hepatocellular carcinoma, and recommended TACE as a standard treatment for hepatocellular carcinoma of Barcelona Clinical Liver Cancer staging (BCLC staging) B. However, TACE can hardly fully embolize tumor blood supply, TACE postoperative hemodynamics and angiogenesis can induce tumor recurrence and metastasis. This paper reviewed characteristics of vascular changes, mechanisms, diagnosis and treatment methods, new progress in the field of hepatocellular carcinoma after TACE. (authors)

  17. Radio-embolization for hepatocellular carcinoma

    Raoul, J.L.; Edeline, J.; Pracht, M.; Boucher, E.; Rolland, Y.; Garin, E.

    2011-01-01

    Hepatocellular carcinoma is now a major public health concern. In intermediate stages (one third of hepatocellular carcinoma patients), chemo-embolization is the standard of care despite a poor tolerance and a moderate efficacy. Moreover, despite recent improvements, this technique seems in a dead end. Radio-embolization could be an excellent tool for such patients. Currently 131 I-Lipiodol, 188 Re-Lipiodol, 90 Y-glass or resin microspheres are available. More recent and promising data come from microspheres, but phase II and III studies are needed before drawing any conclusion. In the future, the combination of radio-embolization with systemic chemotherapy or targeted agents (particularly anti-angiogenic drugs) seems very promising. (authors)

    1998-07-01

    To assess the arterial supply to hepatocellular carcinomas (HCCs) by inferior phrenic arteries (IPA). A total of 126 consecutive cases of HCC were studied by contract-enhanced CT and conventional arteriography. Blood supply from an IPA was suspected when the size of the HCC mass as seen on contrast-enhanced CT did not match the size of the tumor mass as seen on hepatic arteriography. Inferior phrenic arteriography was employed to confirm these findings. HCCs fed by the IPA were analyzed in terms of size, location, and history of prior treatment. In 14 (11%) of the 126 cases, the tumor was found to have a blood supply from an IPA. Eleven of these tumors were located in segments 2 and 7. Three tumors, which had not been treated previously, had a blood supply from an IPA. Six tumors were almost exclusively fed by an IPA and were located in segments 1, 1, and 4. HCCs located in segments which form the bare area of the liver (S1, S2, S7) can be supplied by an IPA. This should be suspected when a lesion or part of a lesion is identified on contrast-enhanced CT but not on hepatic arteriography.

    We retrospectively evaluated the characteristic computed tomographic(CT) findings in nine patients with exohepatic hepatocellular carcinoma(HCC) pathologically prove by surgery(n=2) or percutaneous needle biopsy(n=7). The CT findings of exphepatic HCC were correlated with clinical findings and compared with those of usual HCC. Lesions were in the left lobe(n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four case. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clinical findings such as increased {alpha}-fetoprotein({alpha}-FP), positive hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hyperdense mass with complete or partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.

  3. Cerebrovascular accidents associated with sorafenib in hepatocellular carcinoma.

    Saif, Muhammad W; Isufi, Iris; Peccerillo, Jennifer; Syrigos, Kostas N

    2011-01-01

    Sorafenib is an oral angiogenetic multikinase inhibitor approved in the treatment of renal and hepatocellular carcinoma. Bleeding and venous thrombotic events have been described with angiogenetic agents but cerebrovascular accidents are rarely reported. We report two cases of patients with hepatocellular carcinoma who developed a cerebrovascular accident while on sorafenib. Neither patient had any risk factors for the cerebrovascular events apart from gender and age in the second patient. Laboratory data were noncontributory. The head CT scan did not reveal acute abnormalities. No hemodynamically significant stenosis was visible in the carotid ultrasound, and the echocardiogram showed normal size of the heart chambers and normal systolic function of the left ventricle. Sorafenib was discontinued in both cases. Physicians should monitor patients receiving sorafenib for neurologic symptoms, and in the absence of other etiology, prompt discontinuation of this drug should be considered.

    Two patients with Budd-Chiari syndrome complicated by hepatocellular carcinoma in whom CT and inferior venacavography were carried out are described. The imaging study with CT disclosed: 1) calcified inferior vena cava (IVC) at the level of the diaphragm and lack of enhancement of the IVC and hepatic veins after contrast enhancement, 2) markedly dilated inferior right hepatic vein, 3) marked compensatory enlargement of the caudate lobe, 4) icile-like thrombus extending caudally in the IVC and dilatation of that portion of the IVC, and 5) enlarged and dilated azygos, hemiazygos and anterior longitudinal venous trunk of the internal vertebral venous plexus, and with cavography, 1) the inferior right hepatic vein as a venous outlet to maintain the liver functions, and 2) occlusion of the right and left hepatic vein openings and a communicating vein between the left hepatic and caudate lobe vein.

    1982-08-21

    Having found raised serum calcitonin concentrations in 94% of patients with hepatocellular carcinoma when using a dextran-coated-charcoal radio-immunoassay, we have now repeated the study, using a double-antibody radio-immunoassay, in 102 further patients with hepatocellular carcinoma and 35 matched controls. Serum immunoreactive calcitonin concentrations (iCT) in the controls ranged from 10 to 310 pg/ml (mean 154,6 pg/ml). Values in the tumour patients ranged from 10 to 1,650 pg/ml (mean 302,6 pg/ml). The mean figures were significantly higher in the tumour patients (P smaller than 0,001), 35.5% of them having values above 310 pg/ml. In 65 of the patients serum iCT concentrations were also determined by dextran-coated-charcoal radio-immunoassay. Values ranged from 10 to 10780 pg/ml (mean 2,179 pg/ml). If 1,000 pg/ml is taken as the upper limit of normal, 69% of the patients had raised iCT concentrations. There was a good correlation (r=0,67; P smaller than 0,001) between serum iCT values measured with both methods in 50 patients. If measured by the double-antibody radio-immunoassay method, the serum calcitonin value is not useful as a marker for hepatocellular carcinoma.

    2018-05-29

    Objective: To investigate the expression and clinical significance of KIAA1199 in primary hepatocellular carcinoma. Methods: A total of 136 cases of primary hepatocellular carcinoma tissues and paired adjacent tissues were collected. Immunohistochemistry and Western blot were used to detect the expression of KIAA1199 in primary hepatocellular carcinoma tissues and paired adjacent tissues. The relationship between KIAA1199 and clinicopathological parameter of primary hepatocellular carcinoma was analyzed. Results: The positive rate of KIAA1199 in primary hepatocellular carcinoma was 82.3% (112/136), which was higher than that in paired para-cancerous tissues (14.7%, 20/136). High expression of KIAA1199 was significantly correlated with age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and microvenous invasion (MVI) ( P 0.05). The Kaplan-Meier survival curves indicated that high KIAA1199 expression was associated with poor survival ( P hepatocellular carcinoma, which is significantly correlated with the clinicopathological features and prognosis, high expression of KIAA1199 increased the risk of death in patients with primary hepatocellular carcinoma.

  10. Combined Primary Neuroendocrine Carcinoma and Hepatocellular Carcinoma of the Liver

    Chii-Shuenn Yang

    2009-08-01

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

    Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.

  12. Case of small hepatocellular carcinoma detected only by dynamic sequential computed tomography with table incrementation during arterial portography (DSCTI-AP)

    Nishijima, Hiroshi; Ida, Masahiro; Takayama, Shigeru; Yanaghi, Sekiya; Kuroda, Yuzuru [Fukui Saiseikai Hospital (Japan)

    1984-05-01

    A 62 years old woman was admitted for liver cirrhosis with esophageal varix. Radionuclide liver scintigram, ultrasonogram, computed tomography and infusion hepatic angiography showed no signs of hepatocellular carcinoma (HCC). But DSCTI-AP detected a small solid mass lesion about 1.5cm in diameter in the right lobe of the liver. It was difficult to diagnose this lesion as HCC because of low titer of serum ..cap alpha../sub 1/-fetoprotein. After the esophageal transection for esophageal varices, she was followed as an outpatient. Six months later, serum ..cap alpha../sub 1/-fetoprotein was slightly elevated (130 ng/ml), and all imaging methods were carried out for the detection of HCC. Ultrasonogram, computed tomography, infusion hepatic angiography, DSCTI-AP all showed hepatocellular carcinoma, about 4.5cm in diameter in the same site where a small nodule was visualized by DSCTI-AP performed 5 months ago. This case suggests that DSCTI-AP is a sensitive and useful method for detection of some type of small liver cancer.

  13. Radiofrequency ablation of hepatocellular carcinoma: Mono or multipolar?

    Cartier, Victoire; Boursier, Jérôme; Lebigot, Jérôme; Oberti, Frédéric; Fouchard-Hubert, Isabelle; Aubé, Christophe

    2016-03-01

    Thermo-ablation by radiofrequency is recognized as a curative treatment for early-stage hepatocellular carcinoma. However, local recurrence may occur because of incomplete peripheral tumor destruction. Multipolar radiofrequency has been developed to increase the size of the maximal ablation zone. We aimed to compare the efficacy of monopolar and multipolar radiofrequency for the treatment of hepatocellular carcinoma and determine factors predicting failure. A total of 171 consecutive patients with 214 hepatocellular carcinomas were retrospectively included. One hundred fifty-eight tumors were treated with an expandable monopolar electrode and 56 with a multipolar technique using several linear bipolar electrodes. Imaging studies at 6 weeks after treatment, then every 3 months, assessed local effectiveness. Radiofrequency failure was defined as persistent residual tumor after two sessions (primary radiofrequency failure) or local tumor recurrence during follow-up. This study received institutional review board approval (number 2014/77). Imaging showed complete tumor ablation in 207 of 214 lesions after the first session of radiofrequency. After a second session, only two cases of residual viable tumor were observed. During follow-up, there were 46 local tumor recurrences. Thus, radiofrequency failure occurred in 48/214 (22.4%) cases. By multivariate analysis, technique (P radiofrequency failure. Failure rate was lower with the multipolar technique for tumors radiofrequency, multipolar radiofrequency improves tumor ablation with a subsequent lower rate of local tumor recurrence. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Selective angiography is of great importance in the diagnosis of primary hepatocellular carcinoma. It offers information on the findings, multicentricity, localisation, extension, and type of growth. This paper discusses angiography from the methodical point of view, the findings to be obtained, the types of hepatocellular carcinoma, and the diagnostic efficiency of selective angiography in the evaluation of this type of tumour.

  17. Computed tomography of hepatocellular carcinoma. Comparison with scintigraphy and ultrasonography

    Kaneko, Kuniyuki; Nakata, Hajime; Honda, Hiroshi [University of Occupational and Environmental Health, Kitakyushu, Fukuoka (Japan)

    1983-09-01

    The detectability of hepatocellular carcinoma by computed tomography (CT) was evaluated on 76 cases. The detectability by plain CT was 93% with only slight improvement following a drip infusion of contrast medium. A comparison of scintigraphy, ultrasonography, and CT was also done on 63 cases. From the standpoint of the overall detectability of the tumor, CT was as good as ultrasonography or scintigraphy. Several cases were positive only on either CT or ultrasonography but no case was positive on scintigraphy alone. We believe that the combination of CT and ultrasonography is the most reliable as the screening method.

  18. Metastases of Hepatocellular Carcinoma Misdiagnosed as Isolated Hypertrophic Cardiomyopathy.

    Greco, Assunta; De Masi, Roberto; Orlando, Stefania; Metrangolo, Antonio; Zecca, Vittorio; Morciano, Giancarlo; De Donno, Antonella; Bagordo, Francesco; Piccinni, Giancarlo

    At present, cardiac metastasis of hepatocellular carcinoma is rarely mentioned in the literature. We report a hepatocellular carcinoma patient with cardiac metastasis misdiagnosed as hypertrophic cardiomyopathy in 2011. Two years later, on presentation of syncope, an abnormal ventricular septal size was recorded by ultrasound scan, and was subsequently shown by magnetic resonance imaging to be a tumour lesion. A myocardial biopsy confirmed infiltration of hepatocellular carcinoma. This observation underlines the risk of hepatocellular carcinoma cardiac metastasis, manifested in its infiltrative form as hypertrophic cardiomyopathy. In conclusion, we suggest that the ultrasound appearance of hypertrophic cardiomyopathy in hepatocellular carcinoma patients should be seen as a "red flag" and recommend the introduction of magnetic resonance imaging assessment of transplant candidates.

    2008-01-01

    Objective: To show the computed tomography (CT) usefulness after treatment with transcatheter arterial quimioembolization and radiofrequency ablation of hepatocellular carcinoma. Material and methods: In a period between march 2006 to april 2008 a total of 90 patient presenting 148 nodular lesions with diagnosis of hepatocellular carcinoma were controlled with triphasic CT. All the lesions were treated with minimally invasive procedure. For the treatment, the patients were classified in two groups following Milan criteria. The first group, constituted by 75 patients with 109 nodules, was treated with quimioembolization. The second group, of 15 patients with 25 nodules, was treated with radiofrequency ablation. In our population, a subgroup of 10 patients was treated with both methods. Results: Of 90 patients after CT control on a month, 3 months and for each 3 months during 2 years, on 63 cases (70%) was observed homogeneous accumulation of iodized oil, partial defect without enhancement or absence of enhancement on treated lesions. In these patients a new treatment after initial one was not performed. The remaining 27 patients (30%) underwent new treatment because we founded partial defect or absence of iodized oil with enhancement or peripheral enhancement on arterial phase in treated lesions. In this last group, 16 treated patients (17.7%) had new nodular enhancement on the remaining hepatic parenquimal. Conclusion: The CT unenhanced and the arterial phase on a month and for each 3 months, allow monitoring the effectiveness, residual disease and/or relapse of hepatocellular carcinoma after minimally invasive treatment.

    During the past three decades, the incidence of hepatocellular carcinoma in the United States has tripled. The neuroendocrine character has been observed in some tumor cells within some hepatocellular carcinoma nodules and elevated serum chromogranin A also been reported in patients with hepatocellular carcinoma. The aim of this work was to investigate the role of serum concentration of chromogranin A in patients with hepatocellular carcinoma at different stages. The study population consisted of 96 patients (63 males and 33 females age range 52-84) at their first hospital admission for hepatocellular carcinoma. The control group consisted of 35 volunteers (20 males and 15 females age range 50-80). The hepatocellular carcinoma patients were stratified according the Barcelona-Clinic Liver Cancer classification. Venous blood samples were collected before treatment from each patients before surgery, centrifuged to obtain serum samples and stored at -80° C until assayed. The chromogranin A serum levels were elevated (> 100 ng/ml) in 72/96 patients with hepatocellular carcinoma. The serum levels of chromogranin A were significantly correlated (p<0.05) with alpha-fetoprotein. In comparison with controls, the hepatocellular carcinoma patients showed a significant increase (p<0.001) vs controls. The chromogranin A levels in the Barcelona staging of hepatocellular carcinoma was higher in stage D compared to stage C (p<0.01), to stage B (p<0.001), and to stage A (p<0.001). Molecular markers, such as chromogranin A, could be very useful tools for hepatocellular carcinoma diagnosis. However the molecular classification should be incorporated into a staging scheme, which effectively separated patients into groups with homogeneous prognosis and response to treatment, and thus serves to aid in the selection of appropriate therapy.

    1992-01-01

    Hemodynamic characteristics were studied by using in vivo vascular imaging techniques in 17 resected early stage hepatocellular carcinoma (e-HCC) by comparing them with 49 resected advanced HCCs (ad-HCC) less than 3 cm in diameter. In this study, e-HCC was defined as the nodule being uniformly composed of well-differentiated HCC or adenomatous hyperplastic nodule containing well-differentiated HCC foci within the nodule. In vivo vascular imaging techniques are as follows; US angiography with intraarterial CO 2 microbubbles were performed to assess the tumor arterial vascularity, and CT during arterial portography (CTAP) was performed to assess the portal perfusion within the nodule. Of 17 e-HCC nodules 5 were hypervascular, 5 were isovascular, 4 were hypovascular, and 3 were vascular spot in hypovascular pattern in contrast to 49 ad-HCC nodules, 43 of which were hypervascular and 6 were isovascular. Of 14 e-HCCs, 9 nodules showed perfusion defect and 5 did not on CTAP, whereas all 37 ad-HCCs on which CTAP was performed, showed perfusion defect. Forty-one percent (7/17) of e-HCC showed fatty metamorphosis in contrast to 8% (4/49) of ad-HCC. In conclusion, hemodynamic characteristics of e-HCC are summarized as follows. (1) Arterial tumor neovascularization is relatively low. (2) Portal perfusion is present in some of e-HCC cases. (3) Hypoperfusion state both from arterial and portal supply is present in some of e-HCC cases. (4) Vascular spot in hypovascular pattern is characteristic arterial pattern in AH containing HCC foci. (5) Fatty metamorphosis may be related with hypoperfusion state of the nodule in e-HCC. (author)

    2011-01-01

    Objective: To explore an effective way to treat the vascular spasm occurred during TACE for hepatocellular carcinomas. Methods: During interventional chemoembolization for hepatocellular carcinomas, Fasudil of 2.5 mg was injected via the catheter if vessel spasm occurred, which was followed by DSA to determine the dilatation of the arteries. Adverse effect was observed and recorded. Results: After the injection of Fasudil the vascular spasm was completely relieved in all the 30 cases. The interventional procedure for hepatocellular carcinomas was successfully accomplished in all patients. No obvious side effect occurred. Conclusion: The injection of Fasudil via the catheter is an effective and safe method to eliminate vessel spasm occurred during TACE for hepatocellular carcinomas. (authors)

    Acunas, Buelent; Rozanes, Izzet

    1999-01-01

    This article presents a review of the literature regarding the use of transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). There have been two different approaches to the treatment: (a) percutaneous tumor ablation methods which can be divided into injectable and thermal methods; percutaneous ethanol injection (PEI) is the most widely used method, and (b) TACE. PEI is the treatment of choice for single HCCs smaller or equal to 3 cm in size. For patients with large HCCs combined TACE and PEI is probably the most effective nonsurgical treatment. In the presence of multiple HCC nodules, TACE remains the treatment of choice

  4. Hepatitis C Virus and Hepatocellular Carcinoma

    Full Text Available Hepatitis C virus (HCV, a hepatotropic virus, is a single stranded-positive RNA virus of ~9,600 nt. length belonging to the Flaviviridae family. HCV infection causes acute hepatitis, chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC. It has been reported that HCV-coding proteins interact with host-cell factors that are involved in cell cycle regulation, transcriptional regulation, cell proliferation and apoptosis. Severe inflammation and advanced liver fibrosis in the liver background are also associated with the incidence of HCV-related HCC. In this review, we discuss the mechanism of hepatocarcinogenesis in HCV-related liver diseases.

    To examine if liver stiffness measured by magnetic resonance elastography (MRE) is a risk factor for hepatocellular carcinoma (HCC) in patients with chronic liver disease. By reviewing the records of magnetic resonance (MR) examinations performed at our institution, we selected 301 patients with chronic liver disease who did not have a previous medical history of HCC. All patients underwent MRE and gadoxetic acid-enhanced MR imaging. HCC was identified on MR images in 66 of the 301 patients, who were matched to controls from the remaining patients without HCC according to age. MRE images were obtained by visualising elastic waves generated in the liver by pneumatic vibration transferred via a cylindrical passive driver. Risk factors of HCC development were determined by the odds ratio with logistic regression analysis; gender and liver stiffness by MRE and serum levels of aspartate transferase, alanine transferase, alpha-fetoprotein, and protein induced by vitamin K absence-II. Multivariate analysis revealed that only liver stiffness by MRE was a significant risk factor for HCC with an odds ratio (95 % confidence interval) of 1.38 (1.05-1.84). Liver stiffness measured by MRE is an independent risk factor for HCC in patients with chronic liver disease. (orig.)

    2016-03-01

    Sorafenib followed by fractionated radiotherapy (RT) has been shown to decrease the phagocytic and candidacidal activities of antifungal agents due to radiosensitization. Moreover, sorafenib has been shown to suppress the immune system, thereby increasing the risk for candida colonization and infection. In this study, we present the 2 hepatocellular carcinoma (HCC) patients suffered from epigastric distress caused by esophageal candidiasis who received sorafenib plus RT. Two patients who had received sorafenib and RT for HCC with bone metastasis presented with hiccups, gastric ulcer, epigastric distress, anorexia, heart burn, and fatigue. Empiric antiemetic agents, antacids, and pain killers were ineffective at relieving symptoms. Panendoscopy revealed diffuse white lesions in the esophagus. Candida esophagitis was suspected. Results of periodic acid-Schiff staining were diagnostic of candidiasis. Oral fluconazole (150 mg) twice daily and proton-pump inhibitors were prescribed. At 2-weak follow-up, esophagitis had resolved and both patients were free of gastrointestinal symptoms. Physicians should be aware that sorafenib combined with RT may induce an immunosuppressive state in patients with HCC, thereby increasing their risk of developing esophagitis due to candida species.

    Dichlorodiphenyltrichloroethane (p,p’-DDT), an organochlorine pesticide known to have deleterious health effects in humans, has been linked to hepatocellular carcinoma (HCC) in rodents. A recent study has reported that p,p’-DDT and its most persistent metabolite, dichlorodiphenyldichloroethylene (p,p’-DDE), may also be associated with HCC in humans. To examine whether there is an association between p,p’-DDT and/or p,p’-DDE in a population at high-risk of developing HCC. A nested case-control study was conducted within the 83,794 person Haimen City Cohort in China. Sera and questionnaire data were collected from all participants between 1992 and 1993. The current study included 473 persons who developed HCC and 492 who did not, frequency matched on sex, age and area of residence. p,p’-DDT and p,p’-DDE levels were determined by mass spectrometry. Hepatitis B viral infection status (based on hepatitis B virus surface antigen; HBsAg) was also determined. Adjusting for age, sex, area of residence, HBsAg, family history of HCC, history of acute hepatitis, smoking, alcohol, occupation (farmers) and levels of p,p’-DDT or p,p’-DDE, odds ratios (OR) and 95% confidence intervals (CI) were calculated via unconditional logistic regression, p,p’-DDT and/or p,p’-DDE serum levels were significantly associated with sex, area of residence, occupation, alcohol consumption and cigarette smoking. Overall, the highest quintile of p,p’-DDT was associated with an increased risk of HCC, OR= 2.96 95% CI; 1.19–7.40. There were no statistically significant associations with p,p’-DDE. Overall, these results suggest that recent exposure to p,p’-DDT may increase risk of HCC. PMID:22290210

    Currently, using biopsy specimens to confirm suspicious liver lesions of early hepatocellular carcinoma are not entirely reliable because of insufficient sampling amount and inaccurate sampling location. It is necessary to develop a signature to aid early hepatocellular carcinoma diagnosis using biopsy specimens even when the sampling location is inaccurate. Based on the within-sample relative expression orderings of gene pairs, we identified a simple qualitative signature to distinguish both hepatocellular carcinoma and adjacent non-tumour tissues from cirrhosis tissues of non-hepatocellular carcinoma patients. A signature consisting of 19 gene pairs was identified in the training data sets and validated in 2 large collections of samples from biopsy and surgical resection specimens. For biopsy specimens, 95.7% of 141 hepatocellular carcinoma tissues and all (100%) of 108 cirrhosis tissues of non-hepatocellular carcinoma patients were correctly classified. Especially, all (100%) of 60 hepatocellular carcinoma adjacent normal tissues and 77.5% of 80 hepatocellular carcinoma adjacent cirrhosis tissues were classified to hepatocellular carcinoma. For surgical resection specimens, 99.7% of 733 hepatocellular carcinoma specimens were correctly classified to hepatocellular carcinoma, while 96.1% of 254 hepatocellular carcinoma adjacent cirrhosis tissues and 95.9% of 538 hepatocellular carcinoma adjacent normal tissues were classified to hepatocellular carcinoma. In contrast, 17.0% of 47 cirrhosis from non-hepatocellular carcinoma patients waiting for liver transplantation were classified to hepatocellular carcinoma, indicating that some patients with long-lasting cirrhosis could have already gained hepatocellular carcinoma characteristics. The signature can distinguish both hepatocellular carcinoma tissues and tumour-adjacent tissues from cirrhosis tissues of non-hepatocellular carcinoma patients even using inaccurately sampled biopsy specimens, which can aid early

    Little evidence is available on the relationship between oral corticosteroids use and hepatocellular carcinoma. The objective of this study was to investigate whether oral corticosteroids use correlates with the risk of hepatocellular carcinoma in high risk populations in Taiwan. Using representative claims database established from the Taiwan National Health Insurance Program with a population coverage rate of 99.6%, we identified 102,182 subjects aged 20-84 years with newly diagnosed hepatocellular carcinoma in 2000-2011 as the cases and 102,182 randomly selected subjects aged 20-84 years without hepatocellular carcinoma as the matched controls. In subjects with any one of comorbidities including alcohol-related disease, chronic liver disease, and diabetes mellitus, the adjusted OR of hepatocellular carcinoma was 29.9 (95% CI 28.7, 31.1) for subjects with never use of oral corticosteroids, and the adjusted OR would increase to 33.7 (95% CI 32.3, 35.3) for those with ever use of oral corticosteroids. The adjusted OR of hepatocellular carcinoma was 1.03 for subjects with increasing cumulative duration of oral corticosteroids use for every one year (95% CI 1.01, 1.06), with a duration-dependent effect. The largest OR occurred in subjects with ever use of oral corticosteroids and concurrently comorbid with alcohol-related disease, chronic liver disease, and diabetes mellitus (adjusted OR 122.7, 95% CI 108.5, 138.8). There is a synergistic effect between oral corticosteroids use and the traditional risk factors on the risk of hepatocellular carcinoma. People with risk factors for hepatocellular carcinoma should receive regular ultrasound surveillance, particularly when they currently use oral corticosteroids.

    CT scanning is useful for diagnosing abdominal lymph node metastasis. Using this technique, histologically confirmed abdominal lymph node metastases were detected in nine of 49 patients (33 autopsy cases and 16 laparotomy cases) with hepatocellular carcinoma (hepatoma). Among the 49 patients, three had periportal (6.1%), six peripancreatic (12.2.%) and six para-aortic adenopathies (12.2%). Two of the patients had adenopathy at all three sites. Retrospectively, CT detected two periportal, four peripancreatic and all six para-aortic adenopathies. Most of the hepatomas with adenopathy showed infiltrative growth; tumour thrombosis of the portal vein was a common complication.

    Osama Mohamed Elsanousi

    Full Text Available Introduction: Modern liver surgery in the Sudan started at our institution, The National Ribat University Hospital, in 2002. This study aimed to assess the perioperative events of hepatocellular carcinoma (HCC resection in our institution during the period January 2002 to December 2013 compared to hepatectomies for benign liver pathologies. Methods: The medical records of 114 patients subjected to hepatectomy were divided into the HCC group (cases, and benign group (controls. The characteristics and perioperative events of both groups were assessed and compared. Results: The mean age of the HCC patients was 58.6 ± 7.7 years. The majority of liver resections in the HCC group were minor (72.7%. The mean intraoperative blood loss was 918.8 ml in the HCC group and 720 ml in benign resections group and the difference between them was not significant, p = 0.129. The mean operative duration of HCC resection was 4 hours. The major postoperative complications were encountered in 16 patients (36.4% in the HCC group. HCC group thirty-day postoperative mortality was 9.1%, (n = 4 patients while no patient of the benign group (n = 60 died within that duration, p = .030. Logistic regression multivariate analysis revealed massive bleeding as an independent predictor for major postoperative morbidity, Odds ratio [OR] = 5.899, 95%, Confidence Interval [95% CI], 1.129–30.830, p = .035. Discussion: Our results revealed outcome parameters comparable with the international reports. Conclusion: Further improvements in hepatic surgery in general, and HCC in particular is inevitable.

    Serum alpha-fetoprotein (AFP) level is normal in 30-40% of hepatocellular carcinoma (HCC) patients, and knowledge on its characteristics and clinical outcome is limited. The purpose of this observational study was to determine the clinical presentation, biological behavior and outcome of HCC patients with normal AFP level. Data of 112 consecutive HCC patients with normal AFP level were analyzed retrospectively. Statistical analysis including survival and factors associated with serum AFP level were performed by Kaplan-Meier method and t-test, respectively. Hepatitis B virus infection exited in 83.0% of all 112 HCC patients with normal AFP level. During a mean 52 ± 20 months (range 5-85 months) follow-up, the 1-, 2-, 3-year overall survival (OS) rate was 97.2%, 85.3% and 81.7%, respectively. The OS rates at 3 years stratified by stages at diagnosis were 100%, 96.2%, 85.7%, 11.1% and 0%, respectively for Barcelona Clinic Liver Cancer (BCLC) stage 0-D diseases. Significant difference in OS was observed among patients with BCLC stage 0-D diseases, P level elevated beyond normal figure during follow-up (AFP conversion) in 16 patients, which related with deterioration of liver function, quantitative changes of T helper cell subsets, rapid tumor progression and shorter survival. Patients with sustained normal AFP level had better survival than patients with AFP conversion, P level elevation and the time of AFP elevation to death, P level was relatively optimal. Serum AFP level elevation during follow-up was significantly associated with clinical outcome in terms of OS. © 2017 John Wiley & Sons Australia, Ltd.

    1983-01-01

    Based on a series of CT of the liver in 125 patients with hepatoma and 45 patients with metastatic hepatic tumors, the mode of dilatation of the intrahepatic bile duct was examined. In patients with hepatoma, partia dilatations of intrahepatic bile duct were more commonly seen than general dilatations. On the other hand, there was no case of partial dilatation of the intrahepatic bile duct in patients with metastatic hepatic tumors. It could be concluded that partial dilatation of the intrahepatic bile duct is an useful CT finding to make a diagnosis of hepatoma, particularly to differentiate hepatoma from metastatic hepatic tumor.

    Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma. Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses. In order to identify potential subtypes, two pathologists independen...

    Although Henoch-Schönlein purpura (HSP) is known to be accompanied by malignancies, cases with hepatobiliary cancer are extremely rare. A 62-year-old man with palpable purpura rapidly extending to both lower legs was admitted to our hospital. He was undergoing follow-up for cirrhosis caused by chronic hepatitis B virus infection and hepatocellular carcinoma (HCC). He had renal dysfunction with hematuria and proteinuria and abdominal pain. Based on the clinical presentation and skin biopsy findings, he was diagnosed with HSP. The administration of steroids resulted in the rapid improvement of the patient's symptoms and he was discharged 12 days after admission.

    2017-10-18

    Extra-hepatic spread is present in 5% to 15% of patients with hepatocellular carcinoma (HCC) at the time of diagnosis. The most frequent sites are lung and regional lymph nodes. Here, we report 3 cases of unsuspected HCC with symptoms due to bone lesions as initial presentation. Morphological characteristics and immunohistochemistry from the examined bone were the key data for diagnosis. None of the patients had an already known chronic liver disease. Differential diagnoses with HCC upon ectopic liver disease or hepatoid adenocarcinoma were shown. Therapy with the orally active multikinase inhibitor sorafenib plus symptomatic treatment was indicated.

    2017-11-01

    Lifestyle factors such as smoking, obesity and physical activity have gained interest in the field of hepatocellular carcinoma. These factors play a significant role in the development of hepatocellular carcinoma. Several studies revealed the impact of tobacco consumption on the development of hepatocellular carcinoma and its synergistic effects with viral etiologies (hepatitis B and C). The effects of smoking on survival in patients with a diagnosed hepatocellular carcinoma have not yet been investigated in a Western cohort where hepatitis C infection is a major risk factor. Using data from a prospective cohort of patients with hepatocellular carcinoma who were followed at the University Hospital of Bern, Switzerland, survival was compared by Kaplan-Meier analysis in smokers and nonsmokers, and multivariate Cox regression was applied to control for confounding variables. Of 238 eligible hepatocellular carcinoma patients, 64 were smokers at the time of inclusion and 174 were nonsmokers. Smokers had a significant worse overall survival than nonsmokers (hazard ratio 1.77, 95% confidence interval: 1.22-2.58, P=.003). Analysis of patients according to their underlying liver disease, revealed that smoking, and not nonsmoking, affected survival of hepatitis B virus and C virus-infected patients only. In this subgroup, smoking was an independent predictor for survival (hazard ratio 2.99, 95% confidence interval: 1.7-5.23, Phepatocellular carcinoma. © 2017 John Wiley & Sons A/S.

    2017-07-27

    During the proliferation and metastasis, the tumor cells prefer glycolysis (Warburg effect), but its exact mechanism remains largely unknown. In this study, we demonstrated that phosphoglycerate kinase 1 (PGK1) is an important enzyme in the pathway of metabolic glycolysis. We observed a significant overexpression of PGK1 in hepatocellular carcinoma tissues, and a correlation between PGK1 expression and poor survival of hepatocellular carcinoma patients. Also, the depletion of PGK1 dramatically reduced cancer cell proliferation and metastasis, indicating an oncogenic role of PGK1 in liver cancer progression. Further experiments showed that PGK1 played an important role in MYC -induced metabolic reprogramming, which led to an enhanced Warburg effect. Our results revealed a new effect of PGK1, which can provide a new treatment strategy for hepatocellular carcinoma, as PGK1 is used to indicate the prognosis of hepatocellular carcinoma (HCC).

    Wu Hongping; Wang Junjie; Lu Yang; You Kaizhi

    2010-01-01

    Objective: To evaluate radiology and embolization for hepatocellular carcinoma supplied by gonadal artery. Methods: The medical records of 3 patients with hepatocellular carcinoma supplied by gonadal artery from August 2002 to September 2008 were reviewed. The demography, gonadal artery location, modus operandi, imaging features of liver cancer and prognosis were retrospectively analyzed. Results: Anatomic variation of gonadal artery occurred with the gonadal artery arising from the upper abdominal aorta in 1 patient and from the middle suprarenal artery in 2 patients. The blood supply of the hepatocellular carcinoma derived from the gonadal artery in all 3 patients. No complications occurred in the 6-month follow-up after embolization. Conclusion: Hepatocellular carcinoma may be supplied by gonadal artery with anomalous origin. This anatomic variant can be readily demonstrated by imaging to guide embolization. (authors)

  4. Imaging findings of mimickers of hepatocellular carcinoma

    Tae Kyoung Kim

    2015-12-01

    Full Text Available Radiological imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC as the noninvasive diagnosis of HCC in high-risk patients by typical imaging findings alone is widely adopted in major practice guidelines for HCC. While imaging techniques have markedly improved in detecting small liver lesions, they often detect incidental benign liver lesions and non-hepatocellular malignancy that can be misdiagnosed as HCC. The most common mimicker of HCC in cirrhotic liver is nontumorous arterioportal shunts that are seen as focal hypervascular liver lesions on dynamic contrast-enhanced cross-sectional imaging. Rapidly enhancing hemangiomas can be easily misdiagnosed as HCC especially on MR imaging with liver-specific contrast agent. Focal inflammatory liver lesions mimic HCC by demonstrating arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging. It is important to recognize the suggestive imaging findings for intrahepatic cholangiocarcinoma (CC as the management of CC is largely different from that of HCC. There are other benign mimickers of HCC such as angiomyolipomas and focal nodular hyperplasia-like nodules. Recognition of their typical imaging findings can reduce false-positive HCC diagnosis.

    In order to evaluate the diagnostic ability of CT in hepatocellular carcinoma, four kinds of CT images were comparatively studied by the accuracy and ROC (receiver operating characteristic) curve analysis. As a result, it was clarified that CT images were evaluated more objectively by ROC curve analysis than by accuracy. The diagnostic ability of existence and differentiation of tumor in the liver were higher in order of plain CT, contrast enhanced CT (CECT), bolus CT and CT arteriography (CTA). Therefore, in an usual CT examination intended to make differential diagnosis in space occupying liver disease, bolus CT seems to be indispensable, and also CTA is essential where diagnosis is difficult even by bolus CT.

    The overwhelming need to improve preclinical models in oncology has stimulated research efforts to refine and validate robust orthotopic models that closely mimic the disease population and therefore have the potential to better predict clinical outcome with novel therapies. Sophisticated technologies including bioluminescence, contrast enhanced ultrasound imaging, positron emission tomography, computed tomography and magnetic resonance imaging have been added to existing serum- and histology-based biomarkers to assist with patient selection and the design of clinical trials. The rationale for the use of human hepatocellular carcinoma (HCC) cell lines, implementation of xenograft and orthotopic animal models and utilization of available biomarkers have been discussed, providing guidelines to facilitate preclinical research for the development of treatments for HCC patients.

    2008-09-01

    Hepatocellular carcinoma (HCC) ranks fifth in frequency of cancers worldwide. The incidence of HCC in the United States is rising, primarily due to the number of patients who were infected by hepatitis in the 1960s and 1970s coupled with the rising migrant population from Asia, where hepatitis is widely prevalent. Up to 80% of the patients present with multicentric HCC and advanced liver disease or comorbidities that restrict the option of resection or liver transplantation. The dual blood supply (arterial and portal) to the liver with predominantly arterial supply to the tumor has made embolotherapy a cornerstone in the management of inoperable HCC. The techniques have become refined not only due to the development of microcatheter angiographic capabilities, but also in the ability to deliver a wide variety of therapeutic agents to these tumors. This article reviews the fundamental principles of bland embolization, chemoembolization, and radioembolization in the management of HCC.

    This study assesses the diagnostic value of Lipiodol (iodized oil) and computed tomography (CT) in detecting hepatocellular carcinoma (HCC). Twenty-four patients who were suspected of having HCC received injections of a small amount of Lipiodol, along with an antitumor agent, in the hepatic artery following routine celiac angiography. CT scans obtained 7-10 days after Lipiodol administration demonstrated HCC in distinct contrast to the surrounding noncancerous parenchyma. In particular, the CT-Lipiodol procedure disclosed many small HCC lesions that were not shown by celiac angiography, scintigraphy, CT with an without contrast medium enhancement, and ultrasonography. Although this procedure may miss very small or highly fibrotic lesions, it is recommended for patients suspected of having HCC and for patients for whom hepatic resection is being considered

    The treatment of hepatocellular carcinoma (HCC) is complicated and challenging because of the frequent presence of cirrhosis. Therefore, we propose a novel surgical approach to minimize the invasiveness and risk in patients with HCC, hypersplenism, and esophagogastric varices. This was a retrospective study carried out in 25 patients with HCC and hypersplenism and who underwent simultaneous laparoscopic-guided radio-frequency ablation and laparoscopic splenectomy with endoscopic variceal ligation. Tumor size was restricted to a single nodule of splenectomy. Laparoscopic-guided radio-frequency ablation with laparoscopic splenectomy and endoscopic variceal ligation could be an available technique for patients with HCC <3 cm, hypersplenism, and esophagogastric varices. This approach may help to minimize the surgical risks and results in a fast increase in platelet counts with an acceptable rate of complications.

    Full Text Available Context Liver cirrhosis patients with hepatocellular carcinoma present nutritional alterations and metabolic disorders that negatively impact the prognosis. Objective The objective is to identify alterations in the metabolism of macro and micronutrients among liver cirrhosis patients with and without hepatocellular carcinoma and their relation to the Child-Turcote-Pugh score and Barcelona Clinic Liver Cancer staging. Methods Analytical transversal study, with 31 hepatocellular carcinoma patients and 48 liver cirrhosis patients. Laboratorial exams were carried out. The existence of an association between the biochemical parameters and the disease severity as well as the presence of hepatocellular carcinoma was assessed. Results The metabolic-nutritional profile of liver cirrhosis patients caused by the hepatitis C virus and hepatocellular carcinoma showed alterations, specifically the lipid (total cholesterol, HDL and triglycerides, protein (albumin, creatinine and uric acid, iron (transferrin, iron and ferritin saturation, hematocrit and hemoglobin, zinc and B12 vitamin profiles. There is a relation between nutritional biochemical markers and the Child-Turcote-Pugh, as well as Barcelona Clinic Liver Cancer staging. Conclusions Considering the existence of alterations in the metabolism of nutrients in liver cirrhosis patients with and without hepatocellular carcinoma, and also that conventional nutritional assessment methods present limitations for this population, the biochemical laboratorial exams are valid to complement the diagnosis of the nutritional state in a quick and practical manner.

    The purpose of this study is to assess the effect of Transcatheter Arterial Embolization(TAE) according to angiographic findings in hepatocellular carcinoma. We retrospectively reviewed 50 cases who received TAE for unresectable hepatocellular carcinoma. We analyzed the angiographic findings which were correlated with the effect of TAE. The common angiographic findings of the hepatocellular carcinoma were tumor staining, neo vascularity and enlargement of feeding artery. These angiographic findings were classified into grade 0, +1, +2. Effect of TAE were classified into five patterns; good response, partial response, minimal response, no response and more aggravation. In grading of tumor staining, among 50 cases, the grade 0, +1, +2 were seen in 1 case(2%), 14 cases(28%), 35 cases(70%) each. In grading of enlargement of feeding artery, the grade 0, +1, +2 were seen in 7 cases(14%), 19 cases(38%), 24 cases(48%) each. In grading of neo vascularity, the grade 0, +1, +2 were seen in 6 cases(12%), 15 cases(30%), 29 cases(58%) each. This study showed that the higher grade of angiographic finding, the better effect of TAE. A statistically significant difference was found (P<0.005). But the TAE was not effective in some cases (the maximum diameter of mass is over 10cm, portal vein thrombosis or arteriovenous shunt) in spite of high grade. We believe that these angiographic findings (tumor staining, enlargement of feeding artery, neo vascularity) are one of important indices for anticipating the effect of TAE in patients with unresectable hepatocellular carcinoma

  13. A Case of Hypertensive Crisis without a Surge in Adrenal Hormones after Radiofrequency Ablation as a Treatment for Primary Hepatocellular Carcinoma.

    Lee, Kyung Jin; Ryu, Soo Hyung

    2017-10-25

    Radiofrequency ablation (RFA) is a minimally invasive procedure that has been considered as a relatively safe treatment for patients with small hepatocellular carcinoma (HCC). However, RFA has been shown to be associated with complications including mechanical and thermal damage. A 74-year-old man with hepatitis C virus-associated HCC was admitted to our hospital. Abdominal computed tomography revealed two lobulated-HCC in segments 4 and 5. He had no medical history of hypertension and cardiac disease. During RFA, blood pressure was elevated to 200/140 mmHg. There was no evidence of pulmonary embolism, aortic dissection, or ischemic heart disease. Laboratory findings for catecholamine surge were all within normal limits. After continuous intravenous nitroglycerin and oral beta-blocker treatment, patient's blood pressure gradually decreased and back within the normal range. Hypertensive crisis after RFA treatment for HCC is rare. Most reported cases of hypertensive crisis during RFA were related to adrenal gland injury with a release of catecholamine. In our case, the site of HCC was not close to the adrenal gland, and there was no evidence of catecholamine surge. Herein, we report a very rare case of hypertensive crisis without a surge in adrenal hormones after RFA treatment for HCC.

  14. Giant ectopic liver, hepatocellular carcinoma and pachydermia-a rare genetic syndrome?

    Miny Peter

    2011-08-01

    Full Text Available Abstract Ectopic liver is a very uncommon developmental anomaly that predisposes to the development of hepatocellular carcinoma. We describe the second documented case of a hepatocellular carcinoma developing in the primary liver of a patient with a rare and uncharacterized genetic symptom complex. Also present was the largest ectopic liver ever reported, measuring 12 cm in diameter which contained a solitary focus of metastatic hepatocellular carcinoma. The primary hepatocellular carcinoma is believed to have arisen in the native liver from a hepatic adenoma that was diagnosed 15 years earlier. The patient's uncharacterised condition featured prominent thick, yellow skin over the dorsum of the fingers, and was associated with follicular hyperkeratosis, abnormal plantar creases, digital clubbing, misshaped ears, a lingua plicata and an angioleiomyolipoma of the right kidney. This unique case of hepatocellular carcinoma arising from liver cell adenoma in a patient with an uncharacterised condition featuring a large ectopic liver invites discussion of the role of local factors in carcinogenesis in the parent liver but not the ectopic liver. It also underlines the imperative ongoing need for clinical autopsies.

    Widespread or high-frequency microsatellite instability (MSI) due to the defective DNA mismatch repair (MMR) occurs in the majority of hereditary non-polyposis colorectal cancer and a subset of sporadic malignant tumors. The incidence of MSI and underlying DNA MMR defects have been well characterized in gastrointestinal carcinogenesis, but not in hepatocarcinogenesis. To address the issue, we analyzed 55 Japanese hepatocellular carcinomas using several indicators of DNA MMR defects, such as microsatellite analysis, loss of heterozygosity (LOH) and mutation analysis of MMR genes, methylation of hMLH1 promoter, and frameshift mutations of mononucleotide repeat sequences within possible target genes. Mutation of beta2-microglobulin gene, which is presumably involved in MSI-positive tumor cell escape from immune surveillance was also examined. Some of these analyses were also carried out in 9 human liver cancer cell lines. None of the 3 quasi-monomorphic mononucleotide markers sensitive for MSI, BAT26, BAT25, and BAT34C4 presented shortened unstable alleles in any of the carcinoma, cirrhosis, chronic hepatitis tissues, or cell lines. LOH at MMR genes was infrequent (4.4 approximately 7.1%), and no mutations were detected. Neither hMLH1 hypermethylation nor frameshift mutation in the target genes was detected. No mutations were found in beta2-microglobulin. Widespread MSI due to the defective DNA MMR appears to play little if any part in Japanese hepatocarcinogenesis.

    2010-01-01

    Full Text Available The case of a 72-year-old male patient with HCC is presented in whom percutaneous RFA was used as the sole first-line anticancer treatment, since he denied having partial hepatectomy. The patient underwent RFA two more times, at 1.5 years for treating a local tumor progression at the initial ablation site and at 11 years after the first session for treating a new remote intrahepatic recurrence. He revealed a long-term survival of more than 12 years so far and still remains in excellent clinical status.

    Insulin and other antidiabetic drugs may modulate hepatocellular carcinoma (HCC) risk in diabetics. We have analyzed the role of various antidiabetic drugs on HCC in a nested case-control study using the healthcare utilization databases of the Lombardy Region in Italy. This included 190 diabetic subjects with a hospital discharge reporting a diagnosis of malignant HCC and 3772 diabetic control subjects matched to each case on sex, age, date at cohort entry, and duration of follow-up. Increased risks of HCC were found for use of insulin (odds ratio [OR] = 3.73, 95% confidence interval [CI] 2.52-5.51), sulfonylureas (OR = 1.39, 95%CI 0.98-1.99), and repaglinide (OR = 2.12, 95%CI 1.38-3.26), while a reduced risk was found for use of metformin (OR = 0.57, 95%CI 0.41-0.79). The risk of HCC increased with increasing duration of insulin use (OR = 2.52 for metformin. Our study supports the evidence that patients with diabetes using metformin, and possibly other antidiabetic drugs that increase insulin sensibility, have a reduced risk of HCC, while those using insulin or drugs that increase circulating insulin, such as insulin secretagogues, have an increased risk. Whether these associations are causal, or influenced by different severity of diabetes and/or possible residual bias or misclassification, is still open to discussion.

    Hepatocellular carcinoma (HCC) represents the third cause of cancer-related death. Because HCC is multi-centric with time, excluding the few transplanted patients, sooner or later it becomes untreatable with loco-regional therapies and, until some years ago, it was not responsive to systemic therapies. In 2005 a randomized trial indicated the efficacy of a product containing stem cell differentiation stage factors (SCDSF) taken from zebra fish embryos during the stage in which the totipotent stem cells are differentiating into the pluripotent adult stem cells. In such a trial the patients, with "intermediate" and "advanced" HCC according to BCLC/AASLD guidelines, presented benefit in terms of performance status (PS) and objective tumoral response, with some cases (2.4%) of complete response (CR). The aim of this cohort study is to report the experience of a tertiary referral center on the evidence of cases of CR in patients with "advanced" stage HCC treated with SCDSF as supportive care. CR was regarded as sustained disappearance of the neoplastic areas or blood supply therein, accompanied by normalization of AFP levels. Out of 49 patients consecutively recruited and retrospectively evaluated, 38 had "advanced" stage and 11 "terminal" stage. In 5 patients with "advanced" stage a sustained CR was reported (13.1%). Improvement on PS was obtained in 17 patients (34.6%). No side effects occurred. SCDSF treatment confirmed its efficacy in patients with "advanced" HCC, in terms of PS and tumoral response.

  19. Fibrolamellar Hepatocellular Carcinoma Presenting as Obstructive Jaundice: Uncommon Presentation of a Rare Entity

    Arora, Richa

    2015-01-01

    Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor, significantly different from generic hepatocellular carcinoma with distinct demographics, risk factors, imaging features, histopathology and prognosis. Unlike conventional hepatocellular carcinoma, it presents in young individuals with no preexisting hepatitis or cirrhosis and does not cause elevation of serum alpha feto proteins in most cases. This paper presents a case report of this rare tumor in a young female with an unusual clinical manifestation of obstructive jaundice (which has not been reported so far) along with a review of its imaging and pathological features, with treatment options. Fibrolamellar HCC is a rare variant of classic HCC with different epidemiology, risk factors, clinical manifestations, radiological, pathological and prognostic features. Therefore, it is important to be familiar with the entity for its early diagnosis and management

    Circulating hepatocellular carcinoma cells may be detected by reverse transcription-polymerase chain reaction. We investigated the relationship between circulating hepatocellular carcinoma cells and hepatoma patient survival after different managements and survival periods. Peripheral vein blood (5 ml) samples were obtained from 113 patients with hepatocellular carcinoma and from 33 control subjects (9 with liver cirrhosis after hepatitis B, 14 with chronic hepatitis B, 10 healthy individuals) between January 1, 2009, and December 31, 2013. To detect circulating hepatocellular carcinoma cells in peripheral blood, alpha-fetoprotein messenger RNA was amplified from total RNA extracted from whole blood by reverse transcription-polymerase chain reaction. Alpha-fetoprotein messenger RNA was detected in 59 blood samples from the hepatocellular carcinoma patients (59/113, 52.2%). In contrast, there were no clinical control subjects whose samples showed detectable alpha-fetoprotein messenger RNA. The presence of alpha-fetoprotein messenger RNA in blood seemed to be correlated with the stage (by TNM classification) of hepatocellular carcinoma, serum alpha-fetoprotein value, and the presence of intrahepatic metastasis, portal vein thrombosis, tumor diameter and/or distant metastasis. In addition, alpha-fetoprotein messenger RNA was detected in the blood of 25 patients showing distant metastasis at extrahepatic organs (100%), in contrast to 32 of 88 cases without metastasis (36.4%). All the patients with hepatocellular carcinoma were followed. Seventeen patients with resection of a T 2 stage hepatocellular carcinoma had a survival of 3.2 years after surgical management, 38 cases with resection of a T3 stage hepatocellular carcinoma had a 1.3-year survival, and only 37 cases with T4 stage disease after different treatments except surgery survived for 0.6 years (P <0.01). The presence of alpha-fetoprotein messenger RNA in peripheral blood may be an indicator of circulating

    1985-10-15

    Twenty cases of hepatocellular carcinoma were examined by selective celiac and superior mesenteric arteriography. Obstruction of the main portal vein due to tumor thrombus was revealed in 7 cases and 3 of these cases had cavernous transformation of the portal vein (CTPV). The authors intended in this study to evaluate CTPV group and non-CTPV group clinically and radiologically. The results obtained are as follows: 1. The duration of illness was shorter in CTPV group than non- CTPV group. 2. There was no significant difference in tumor size between two groups ,and main portion of tumor was located in the right lobe in both groups. 3. Arterio portal shunt was present in 2 of 4 cases in non-CTPV group, but was no present at all in CRPV groups. 5. There wa no significant difference in blood chemistry between two groups. 6. CTPV may play an important role maintain the hepatic blood flow.

  2. Efficacy of sorafenib in BRAF-mutated non-small-cell lung cancer (NSCLC) and no response in synchronous BRAF wild type-hepatocellular carcinoma: a case report

    2016-01-01

    Sorafenib is a multi-targeted kinase inhibitor with a demonstrated activity in renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC), and it is currently used for the treatment of these pathologies. Ongoing clinical trials are studying its activity in other malignancies, such as non-small-cell lung cancer (NSCLC). However, no biological marker is known to define either the sensitivity or resistance to the drug. Here we report a case of a patient with two synchronous tumors, HCC and NSCLC, with metastases in the contralateral lung and bone. The patient was treated with gemcitabine as first line, with a resulting progressive disease after two months, and then with sorafenib at standard dosage in the second line setting. After 6 months of treatment CT scan showed a partial response in the primary lesion of the lung, complete response of the metastasis in the contralateral lung, and stability of HCC. The patient had progression in the lung, liver and bone after 13 months of therapy. A molecular characterization of NSCLC and HCC lesions was performed, revealing a BRAF exon 11 mutation (G469V) only in NSCLC. We hypothesize that the response observed in NSCLC lesions could be due to the presence of BRAF mutation, and that this alteration could be responsible in determining sorafenib sensitivity. Results observed in this case encourage further research on the activity of sorafenib in both HCC and NSCLC, based on the presence of BRAF mutation. This could lead to a selection of HCC patients to be treated with this drug, and could help identify a novel treatment strategy for BRAF-mutated NSCLC patients

  3. Overexpression of Rabl3 and Cullin7 is associated with pathogenesis and poor prognosis in hepatocellular carcinoma.

    2017-09-01

    The expression of Rabl3 and Cullin7 is relevant to the carcinogenesis of certain cancers. However, the relationship of this expression with hepatocellular carcinoma remains unclear. To study the protein expression of Rabl3 and Cullin7 and to evaluate their role in hepatocarcinogenesis, in 162 cases of hepatocellular carcinoma, we used immunohistochemistry to investigate the expression of Rabl3 and Cullin7 in both the cancer tissues and the normal hepatic tissues around the hepatocellular carcinoma. The results demonstrated that the rates of positive Rabl3 and Cullin7 expression were 80.2% and 69.1%, respectively, in hepatocellular carcinoma tissues. However, the rates of positive Rabl3 and Cullin7 expression were 31.5% and 29.0%, respectively, in adjacent normal hepatic tissues. Rabl3 and Cullin7 were expressed at significantly higher rates in hepatocellular carcinoma compared with adjacent normal hepatic tissues (Phepatocellular carcinoma tissues of patients with lymph node metastasis, tumor thrombi in the portal vein and an advanced clinical stage (Phepatocellular carcinoma cohort. Moreover, patients with positive expression for both Rabl3 and Cullin7 had a remarkably shorter survival time compared with patients with negative expression for both proteins (Phepatocellular carcinoma and could be used as a prognostic indicator in patients with hepatocellular carcinoma.

  4. Clinical and laboratory features of hepatocellular carcinoma

    Andrés Cárdenas

    2007-02-01

    Full Text Available

    The clinical presentation of hepatocellular carcinoma (HCC differs between patients in developing countries (African and Chinese populations from those in industrialized countries. In industrialized countries, HCC co-exists with symptomatic cirrhosis in 80% of cases and clinical manifestations are usually related to those of the underlying disease. On the other hand, patients from developing countries have HCC and cirrhosis in approximately 40% of cases. Underlying cirrhosis in many cases is not advanced and does not produce any symptoms or associated symptoms are masked by those of the tumor (right upper quadrant pain, mass in the upper abdomen, weight loss and weakness. In a subset of patients, there are no clinical manifestations as HCC may occur in the context of hepatitis B infection without cirrhosis.

    Clinical Manifestations

    In Western countries, nearly 35% percent of patients with HCC are asymptomatic. Some of the most common clinical manifestations include: abdominal pain (53-58% of patients, especially in epigastrium or right upper quadrant, abdominal mass (30%, weight loss, malaise, anorexia, cachexia, jaundice or fever.

    Physical Exam

    Physical findings vary with the stage of disease. The patient may exhibit slight or moderate wasting when first seen. In patients with cirrhosis, typical stigmata of chronic liver disease may be present. In advanced stages of HCC the liver may be enlarged and there is significant tenderness. An arterial bruit may be heard over the liver

    This paper deals with diagnostic values of intraarterial digital subtraction angiography (IADSA) for evaluating hepatocellular carcinoma. The present series consists of 44 patients with hepatocellular carcinoma, who underwent IADSA combined with conventional hepatic angiography 67 times in total. The evaluated vessels by IADSA included 70 hepatic arteries and 36 portal veins. Comparative studies on the image quality of IADSA with conventional angiography were made in referring to the tumor stain for arteriograms and resolution of intrahepatic portal branches for portograms. Diagnostic superiority including equality of DSA image to conventional was noted in arteriograms: 72.7 % in the right lobe and 86 % in the left. Most deteriorated DSA images were caused by misregistration artifacts. IADSA portography revealed basically diagnostic values to demonstrate lobar, segmental or more peripheral branches in about 95 % of cases studied. DSA, characterized by high contrast resolution and real-time subtraction, offered important and effective informations for interventional angiography as well as resectability of the tumors, requiring less contrast medium.

    To evaluate a different decision tree for safe liver resection and verify its efficiency. A total of 2457 patients underwent hepatic resection between January 2004 and December 2010 at the Chinese PLA General Hospital, and 634 hepatocellular carcinoma (HCC) patients were eligible for the final analyses. Post-hepatectomy liver failure (PHLF) was identified by the association of prothrombin time 50 μmol/L (the "50-50" criteria), which were assessed at day 5 postoperatively or later. The Swiss-Clavien decision tree, Tokyo University-Makuuchi decision tree, and Chinese consensus decision tree were adopted to divide patients into two groups based on those decision trees in sequence, and the PHLF rates were recorded. The overall mortality and PHLF rate were 0.16% and 3.0%. A total of 19 patients experienced PHLF. The numbers of patients to whom the Swiss-Clavien, Tokyo University-Makuuchi, and Chinese consensus decision trees were applied were 581, 573, and 622, and the PHLF rates were 2.75%, 2.62%, and 2.73%, respectively. Significantly more cases satisfied the Chinese consensus decision tree than the Swiss-Clavien decision tree and Tokyo University-Makuuchi decision tree (P decision trees. The Chinese consensus decision tree expands the indications for hepatic resection for HCC patients and does not increase the PHLF rate compared to the Swiss-Clavien and Tokyo University-Makuuchi decision trees. It would be a safe and effective algorithm for hepatectomy in patients with hepatocellular carcinoma.

    Sorafenib is widely used for unresectable and metastatic hepatocellular carcinomas. Radiation recall dermatitis (RRD) is an acute inflammatory reaction confined to previously irradiated skin that occurs after the administration of certain drugs. RRD after sorafenib treatment is rare; five cases have been reported thus far. We describe a 44-year-old man irradiated for chest wall bone metastasis from hepatocellular carcinoma. Eight days after radiotherapy completion, systemic therapy for metastatic hepatocellular carcinoma was initiated with sorafenib treatment. Eleven days after starting sorafenib, the patient complained of erythematous rash with pruritus in the chest wall, in a location consistent with the previous radiation field. Sorafenib was continued at the same dose, despite the RRD. The skin reaction subsided over the next 2 weeks without any medical intervention.

  4. Dynamic computed tomography of hepatocellular carcinoma with particular reference to capsule

    Otsuji, Hideaki [Nara Prefectural Hospital (Japan); Uchida, Hideo; Ohishi, H

    1983-11-01

    Dynamic CT of 117 hepatocellular carcinoma was analyzed about the capsule. Capsules were detected in 57 cases (49%) and they were classified into three types. The tumor showed high density during 15 to 26 sec after bolus injection of conrast medium, but the capsule was not enhanced. Incidence of the capsule enhanced as ring high density was 73% during 37 to 90 sec and over 90% after 4 min. Dynamic CT was very useful in the elucidation of hemodynamics of capsules of hepatocellular carcinoma.

  5. Birth order and risk of hepatocellular carcinoma in chronic carriers of hepatitis B virus: a case-control study in The Gambia.

    Early age at infection with Hepatitis B virus (HBV) increases the risk of chronic infection. Moreover, early HBV infection may further independently increase the risk of hepatocellular carcinoma (HCC) beyond its effect on chronicity. The distribution of birth order, a proxy for mode and timing of HBV transmission, was compared in The Gambia between hepatitis B surface antigen (HBsAg)-positive HCC cases recruited from hospitals (n = 72) and two HBsAg-positive control groups without HCC: population-based controls from a community HBV screening (n = 392) and hospital-based controls (n = 63). HCC risk decreased with increasing birth order in the population-based case-control analysis. Using first birth order as the reference, the odds ratios were 0.52 (95% CI: 0.20-1.36), 0.52 (0.17-1.56), 0.57 (0.16-2.05) and 0.14 (0.03-0.64) for second, third, fourth and greater than fourth birth order respectively (P = 0.01). A similar inverse association was observed in the hospital-based case-control comparison (P = 0.04). Compared to controls, HCC cases had earlier birth order, a proxy for young maternal age and maternal HBV viraemia at birth. This finding suggests that in chronic HBV carriers perinatal mother-to-infant transmission may increase HCC risk more than horizontal transmission. Providing HBV vaccine within 24 h of birth to interrupt perinatal transmission might reduce the incidence of HCC in The Gambia. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  6. Diagnostic and therapeutic management of hepatocellular carcinoma

    Bellissimo, Francesco; Pinzone, Marilia Rita; Cacopardo, Bruno; Nunnari, Giuseppe

    2015-01-01

    Hepatocellular carcinoma (HCC) is an increasing health problem, representing the second cause of cancer-related mortality worldwide. The major risk factor for HCC is cirrhosis. In developing countries, viral hepatitis represent the major risk factor, whereas in developed countries, the epidemic of obesity, diabetes and nonalcoholic steatohepatitis contribute to the observed increase in HCC incidence. Cirrhotic patients are recommended to undergo HCC surveillance by abdominal ultrasounds at 6-mo intervals. The current diagnostic algorithms for HCC rely on typical radiological hallmarks in dynamic contrast-enhanced imaging, while the use of α-fetoprotein as an independent tool for HCC surveillance is not recommended by current guidelines due to its low sensitivity and specificity. Early diagnosis is crucial for curative treatments. Surgical resection, radiofrequency ablation and liver transplantation are considered the cornerstones of curative therapy, while for patients with more advanced HCC recommended options include sorafenib and trans-arterial chemo-embolization. A multidisciplinary team, consisting of hepatologists, surgeons, radiologists, oncologists and pathologists, is fundamental for a correct management. In this paper, we review the diagnostic and therapeutic management of HCC, with a focus on the most recent evidences and recommendations from guidelines. PMID:26576088

  7. Updates in the Management of Hepatocellular Carcinoma

    Frenette, Catherine

    2011-01-01

    Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death, and its increasing incidence worldwide is a cause for concern. Fortunately, advances in diagnostic and therapeutic approaches have contributed to earlier detection and treatment. As cancer epidemiology studies continue to elucidate the natural history of liver diseases, greater understanding of HCC has led to improved risk stratification and earlier enrollment of high-risk patients in cancer screening and surveillance programs. Improved survival rates among HCC patients also reflect significant advances in available treatment options. Advances in surgical techniques are pushing the boundaries of resection for localized disease, and progress in the field of transplantation has led to refinements in listing criteria and improved post-transplantation outcomes. The evolving field of locoregional therapies—including percutaneous ablation and transarterial chemoembolization—continues to provide novel therapeutic options that can be used in place of, or in addition to, surgical approaches. Recent advances in systemic multikinase inhibitor therapies have also demonstrated significant benefits for advanced-stage disease, and these therapies also show promise as adjuvant treatments for earlier-stage disease. This article provides an update on the management of HCC, with a focus on revised guidelines for screening and an in-depth discussion of emerging novel therapies. PMID:21346848

  8. Genetic alterations in hepatocellular carcinoma: An update

    Niu, Zhao-Shan; Niu, Xiao-Jun; Wang, Wen-Hong

    2016-01-01

    Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Although recent advances in therapeutic approaches for treating HCC have improved the prognoses of patients with HCC, this cancer is still associated with a poor survival rate mainly due to late diagnosis. Therefore, a diagnosis must be made sufficiently early to perform curative and effective treatments. There is a need for a deeper understanding of the molecular mechanisms underlying the initiation and progression of HCC because these mechanisms are critical for making early diagnoses and developing novel therapeutic strategies. Over the past decade, much progress has been made in elucidating the molecular mechanisms underlying hepatocarcinogenesis. In particular, recent advances in next-generation sequencing technologies have revealed numerous genetic alterations, including recurrently mutated genes and dysregulated signaling pathways in HCC. A better understanding of the genetic alterations in HCC could contribute to identifying potential driver mutations and discovering novel therapeutic targets in the future. In this article, we summarize the current advances in research on the genetic alterations, including genomic instability, single-nucleotide polymorphisms, somatic mutations and deregulated signaling pathways, implicated in the initiation and progression of HCC. We also attempt to elucidate some of the genetic mechanisms that contribute to making early diagnoses of and developing molecularly targeted therapies for HCC. PMID:27895396

  9. Nonalcoholic fatty liver disease and hepatocellular carcinoma

    LI Liangping

    2016-03-01

    Full Text Available As the etiology of hepatocellular carcinoma (HCC has been changing, the incidence of HCC related to nonalcoholic fatty liver disease (NAFLD is gradually increasing in developed countries in Europe and America and some countries in Asia. This article introduces the close association between NAFLD and HCC, risk factors, clinicopathological features, and prevention and screening, and points out that although the incidence of NAFLD is not as high as that of hepatitis B- or hepatitis C-related HCC, there are a large absolute number of NAFLD patients, especially the high-risk patients with diabetes and obesity, or liver fibrosis/cirrhosis, due to a huge base number of NAFLD patients. NAFLD-related HCC is commonly seen in the elderly with various comorbidities and a poor prognosis. This article also points out that the prevention should focus on the effective treatment of NAFLD. The strict screening of high-risk population is the strategy for the diagnosis of early-stage HCC. At present, the sensitivity of alpha-fetoprotein is relatively low, and imaging examinations including computed tomography are the main screening methods; however, there are no measures for early warning of NAFLD-related HCC.

  10. Ectopic hepatocellular carcinoma in a dog.

    Burton, I R; Limpus, K; Thompson, K G; Owen, M C; Worth, A J

    2005-12-01

    A 14-year-old neutered male Bearded Collie was presented with a history of recurrent, intermittent urinary incontinence of 7 years duration. A large, firm, non-painful mass was found in the mid-abdominal region on palpation. Ultrasonography of the mass revealed a compartmentalised structure with mixed echogenicity, and which did not appear to be associated with any of the abdominal organs. Ultrasound-guided fine needle aspirates contained several clusters of epithelial cells with cytological features of hepatocytes. At exploratory laparotomy, the mass was found in the gastrosplenic ligament within the greater omentum. PATHOLOGICAL FINDINGS AND DIAGNOSIS: Histopathologically, the mass consisted of sheets of hepatocytes, but without the characteristic hepatic architecture. The cells showed moderate variation in nuclear size and were sometimes binucleate. A diagnosis of hepatocellular carcinoma (HCC) in the mesentery was made. The presence of ectopic hepatic tissue has been reported rarely in man and cats, but not in the dog. Neoplastic transformation of ectopic hepatic tissue is seen in man. This is the first report of the presentation, clinical findings and treatment of a dog with ectopic HCC.

  11. Potentiality of immunotherapy against hepatocellular carcinoma

    Tsuchiya, Nobuhiro; Sawada, Yu; Endo, Itaru; Uemura, Yasushi; Nakatsura, Tetsuya

    2015-01-01

    Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is the fifth most common cancer worldwide and the second leading cause of cancer-related death. Despite the high incidence, treatment options remain limited for advanced HCC, and as a result prognosis continues to be poor. Current therapeutic options, surgery, chemotherapy and radiotherapy, have only modest efficacy. New treatment modalities to prolong survival and to minimize the risk of adverse response are desperately needed for patients with advanced HCC. Tumor immunotherapy is a promising, novel treatment strategy that may lead to improvements in both treatment-associated toxicity and outcome. The strategies have developed in part through genomic studies that have yielded candidate target molecules and in part through basic biology studies that have defined the pathways and cell types regulating immune response. Here, we summarize the various types of HCC immunotherapy and argue that the newfound field of HCC immunotherapy might provide critical advantages in the effort to improve prognosis of patients with advanced HCC. Already several immunotherapies, such as tumor-associated antigen therapy, immune checkpoint inhibitors and cell transfer immunotherapy, have demonstrated safety and feasibility in HCC patients. Unfortunately, immunotherapy currently has low efficacy in advanced stage HCC patients; overcoming this challenge will place immunotherapy at the forefront of HCC treatment, possibly in the near future.

    2006-01-01

    Purpose: To retrospectively evaluate the safety and effectiveness of repeated proton beam therapy for newly developed or recurrent hepatocellular carcinoma (HCC). Methods and Materials: From June 1989 through July 2000, 225 patients with HCC underwent their first course of proton beam therapy at University of Tsukuba. Of them, 27 with 68 lesions who had undergone two or more courses were retrospectively reviewed in this study. Median interval between the first and second course was 24.5 months (range 3.3-79.8 months). Median total dose of 72 Gy in 16 fractions and 66 Gy in 16 fractions were given for the first course and the rest of the courses, respectively. Results: The 5-year survival rate and median survival period from the beginning of the first course for the 27 patients were 55.6% and 62.2 months, respectively. Five-year local control rate for the 68 lesions was 87.8%. Of the patients, 1 with Child-Pugh class B and another with class C before the last course suffered from acute hepatic failure. Conclusions: Repeated proton beam therapy for HCC is safe when the patient has a target in the peripheral region of the liver and liver function is Child-Pugh class A

  13. Hepatocellular carcinoma: a systems biology perspective

    Lorenza Alice D'alessandro

    2013-02-01

    Full Text Available Hepatocellular carcinomas (HCC have different etiology and heterogenic genomic alterations lead to high complexity. The molecular features of HCC have largely been studied by gene expression and proteome profiling focusing on the correlations between the expression of specific markers and clinical data. Integration of the increasing amounts of data in databases has facilitated the link of genomic and proteomic profiles of HCC to disease state and clinical outcome. Despite the current knowledge, specific molecular markers remain to be identified and new strategies are required to establish novel targeted therapies. In the last years, mathematical models reconstructing gene and protein networks based on experimental data of HCC have been developed providing powerful tools to predict candidate interactions and potential targets for therapy. Furthermore, the combination of dynamic and logical mathematical models with quantitative data allows detailed mechanistic insights into system properties. To address effects at the organ level, mathematical models reconstructing the three-dimensional organization of liver lobules were developed. In the future, integration of different modeling approaches capturing the effects at the cellular up to the organ level is required to address the complex properties of HCC and to enable the discovery of new targets for HCC prevention or treatment.

    After arterial embolization therapy, two cases of hepatocellular carcinoma were followed up by RI scintigraphy, and the results were compared with those of angiography. A correlation between changes in /sup 67/Ga-citrate distribution and angiographical picture was found. This suggested that tumor scintigraphy is useful for follow-up observation after arterial embolization therapy.

  1. Clinical significance of computed tomographic arteriography for minute hepatocellular carcinoma

    Itoh, H; Matsui, O; Suzuki, M; Ida, M; Kitagawa, K [Kanazawa Univ. (Japan). School of Medicine

    1982-03-01

    Computed tomographic arteriography (CTA) can clearly demonstrate minute hepatocellular carcinoma (H.C.C.) more than 2 cm in diameter as an enhanced mass lesion. In this case the precise localization of H.C.C. becomes so obvious that CTA plays an important role to evaluate its resectability. However, H.C.C. of the size from 2 cm to 1 cm indiameter, which is visualized with celiac and infusion hepatic angiography, becomes more difficult in detection, and particularly H.C.C. of less than 1 cm in diameter can hardly be recognized, nor be diagnosed as a malignant nodule by CTA, therefore it appears that in these sizes of H.C.C. the detectability of CTA is not superior to the hepatic angiography.

  2. Immunostimulatory monoclonal antibodies for hepatocellular carcinoma therapy. Trends and perspectives

    Guillermo D. Mazzolini

    2018-01-01

    Full Text Available Hepatocellular carcinoma (HCC is the second cause of cancer-related death in the world and is the main cause of death in cirrhotic patients. Unfortunately, the incidence of HCC has grown significantly in the last decade. Curative treatments such as surgery, liver transplantation or percutaneous ablation can only be applied in less than 30% of cases. The multikinase inhibitor sorafenib is the first line therapy for advanced HCC. Regorafenib is the standard of care for second-line patients. However, novel and more specific potent therapeutic approaches for advanced HCC are still needed. The liver constitutes a unique immunological microenvironment, although anti-tumor immunity seems to be feasible with the use of checkpoint inhibitors such as nivolumab. Efficacy may be further increased by combining checkpoint inhibitors or by applying loco-regional treatments. The success of immune checkpoint blockade has renewed interest in immunotherapy in HCC

    2016-12-15

    Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Besides the improvement in diagnostics and therapy the quantity of new cases and fatalities per year are equal. The main risk factors for HCC developing are liver cirrhosis (causing 90% of HCCs), non-alcoholic fatty liver disease and chronic hepatitis B infection. Therefore, it is recommended to perform an ultrasound screening on patients at risk every 6 month to detect HCC-lesions early. HCC can be definitely diagnosed by imaging techniques using contrast agent such as contrast-enhanced-ultrasound (CEUS), contrast-enhanced-MRI (CE-MRI) and contrast-enhanced-CT (CE-CT). MRI has several advantages compared to the other modalities due to the multi-parametric approach and a higher sensitivity for tumor detection.

  4. How to detect hepatocellular carcinoma in cirrhosis

    Ward, Janice; Robinson, Philip J. [Department of Clinical Radiology, St. James' s University Hospital, Beckett Street, Leeds LS9 7TF (United Kingdom)

    2002-09-01

    Cirrhosis predisposes to hepatocellular carcinoma (HCC) which develops by sequential steps of de-differentiation of hepatocytes from regenerative nodules via borderline (dysplastic) nodules to frankly malignant HCC. Effective treatment depends on early recognition of HCC, so the key tasks for imaging are firstly recognising the presence of a suspicious lesion, and secondly differentiating between benign, borderline and malignant nodules. Screening of high-risk cirrhotic patients with sonography and measurement of alpha fetoprotein (AFP) is helpful but will not reliably differentiate small HCC from benign or dysplastic nodules. Large HCCs can usually be recognised by their characteristic morphology on imaging, but the appearances of smaller benign and malignant nodules show considerable overlap on unenhanced sonography, CT and MRI. Increasing degrees of histological malignancy are associated with increasing arterialisation and loss of portal blood supply, so the recognition of HCC requires the use of dynamic imaging with contrast-enhanced CT or T1-weighted MRI with gadolinium enhancement. Sonography with microbubble contrast media now offers another method for detecting arterialised nodules; however, some non-malignant nodules show arterial hypervascularity and a minority of HCCs are hypovascular, so the assessment of perfusion does not conclusively distinguish benign from malignant lesions. Kupffer cell function is another attribute of liver tissue which can be explored using MRI with superparamagnetic iron oxide particles (SPIO). Experience thus far suggests that uptake of SPIO is an effective discriminator between benign and malignant nodules. The combination of SPIO with gadolinium-enhanced MRI offers the opportunity for imaging characterisation of cirrhotic nodules by cellular function as well as by blood supply, and this approach is now proposed as the examination of choice for detecting HCC in cirrhosis.

  5. Epidemiology of hepatocellular carcinoma in India.

    Acharya, Subrat K

    2014-08-01

    Indian data on epidemiology of HCC is not available. Cancer is not a reportable disease in India and the cancer registries in India are mostly urban. National cancer registry program of the Indian Council of Medical Research (ICMR) has been recently expanded to include 21 population based and 6 hospital based cancer registries. The last published registry data by ICMR available in the cancer registry website (www.ncrpindia.org) was in 2008 which provides information on various cancers from 2006 to 2008. The other source of information was the report published by International Agency for Research on Cancer (WHO). According to these available data the age adjusted incidence rate of hepatocellular carcinoma (HCC) in India for men ranges from 0.7 to 7.5 and for women 0.2 to 2.2 per 100,000 population per year. The male:female ratio for HCC in India is 4:1. The age of presentation varies from 40 to 70 years. According to a study conducted by verbal autopsy in 1.1 million homes representing the whole country, the age standardized mortality rate for HCC in India for men is 6.8/100,000 and for women is 5.1/100,000. According to another study the incidence of HCC in cirrhotics in India is 1.6% per year. The unpublished data from various tertiary care centers suggest that the incidence of HCC is increasing in India. There is a need for a multi-centric HCC registry under the aegis of INASL.

  6. Targeting cancer stem cells in hepatocellular carcinoma

    2014-12-01

    Full Text Available Aiwu Ruth He,1 Daniel C Smith,1 Lopa Mishra2 1Lombardi Comprehensive Cancer Center, Georgetown University, Washington, DC, 2Department of Gastroenterology, Hepatology, and Nutrition, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: The poor outcome of patients with hepatocellular carcinoma (HCC is attributed to recurrence of the disease after curative treatment and the resistance of HCC cells to conventional chemotherapy, which may be explained partly by the function of liver cancer stem cells (CSCs. Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

    Purpose: We report our preliminary experience of combining sunitinib and helical tomotherapy in patients with advanced HCC. Methods and Materials: Records of patients with advanced hepatocellular carcinoma (HCC) treated with helical tomotherapy and sunitinib after radiation therapy (RT) from March 2007 to August 2008 were retrospectively reviewed. We report acute toxicities, radiologic response, serial α-fetoprotein (AFP) kinetics, and survival. Results: Of 23 evaluable patients, 60% had ≥2 hepatic lesions, extrahepatic disease was present in 5 (21.7%), and all received 2 tablets (25 mg) of sunitinib at least 1 week before, during, and 2 weeks after RT. Thirteen patients continued maintenance sunitinib after RT until disease progression. Hypofractionated RT with a median target dose of 52.5 Gy/15 fractions was delivered. An objective response was achieved in 74% of patients. The 1-year survival rate was 70%, with median survival of 16 months. Multivariate analysis showed that maintenance sunitinib was the most significant factor for survival. The time to progression was 10 months in the maintenance group compared with 4 months in the control group. Eighteen out of 21 patients with elevated AFP (85.7%) had ≥50% decline of AFP within 2 months after RT. There were three episodes of upper gastrointestinal bleeding and one episode of pancreatitis; 10 patients had ≥Grade 2 elevation of liver enzymes, and 15 had ≥Grade 2 thrombocytopenia. Conclusions: These preliminary results suggest that sunitinib and helical tomotherapy yield high Response Evaluation Criteria in Solid Tumors (RECIST) and AFP response rates in advanced HCC with an acceptable safety profile. Maintenance sunitinib after RT potentially prolongs survival. A randomized trial is warranted.

    For assessment of the value of delayed hepatobiliary imaging with technetium 99m (/sup 99m/Tc)-(Sn)-N-pyridoxyl-5-methyltryptophan (/sup 99m/Tc-PMT) for specific diagnosis of hepatocellular carcinoma, 88 patients with various malignant and benign liver diseases (49 with hepatocellular carcinoma, 4 with cholangiocellular carcinoma, 10 with metastatic liver carcinoma, 2 with liver cysts, 2 with liver hemangioma, 1 with liver abscess, 2 with intrahepatic lithiasis, 12 with liver cirrhosis, and 6 with chronic hepatitis) were studied. In 20 (41%) of the 49 patients with hepatocellular carcinoma, greater uptake of /sup 99m/Tc-PMT by the tumor than by the surrounding liver tissue was seen in delayed hepatobiliary images, whereas in eight patients (16%), equilibrated uptake was seen. No increased uptake of the radioisotope by hepatic lesions was seen in 21 patients with localized liver diseases other than hepatoma. Moreover, in 18 patients with diffuse liver diseases, no focal accumulation of the radioisotope was seen in delayed /sup 99m/Tc-PMT images. In addition, of 28 patients with hepatocellular carcinoma in whom the serum alpha-fetoprotein level showed little or no increase, 12 showed increased uptake of /sup 99m/Tc-PMT by the tumor. In assessing delayed /sup 99m/Tc-PMT images, however, it was necessary to consider following complications: accumulation of tracer in obstructed and dilated biliary trees; retention of radioactivity in nonneoplastic liver tissues; difficulties in evaluating /sup 99m/Tc-PMT uptake by small hepatic tumors; overlapping of radioactivity in the gut and gallbladder in delayed /sup 99m/Tc-PMT images of tumors. This study indicates that delayed /sup 99m/Tc-PMT images can be useful in the diagnosis of hepatocellular carcinoma

    Hepatocellular carcinoma is one of the most frequent types of malignant tumors in the world. There is growing evidence of the relationship between it development and obesity. The mechanism that links obesity to cancer is still not fully understood; however, it is essential to the understanding the adipose tissue in metabolic changes related to obesity and hepatocellular carcinoma. To review the influence of serum leptin levels in patients with hepatocelular carcinoma. Systematic review of the literature based on the methodology of the Cochrane Institute. The search for articles was in the database: Science Direct, Scielo, Medline, Lilacs e Pubmed. The key words used were hepatocellular carcinoma, leptin, adipokine. After evaluation of individual studies, were selected seven studies. The results previously studied are still inconsistent and contradictory, and leptin can be effectively involved in the occurrence and development of hepatocellular carcinoma. Therefore, it is necessary to develop prospective, well-designed and conducted focusing on the role and specific mechanisms of this hormone in patients with hepatocellular carcinoma, so that new correlations can be properly supported. O carcinoma hepatocelular é um dos tipos mais frequentes de tumores malignos no mundo. Há crescentes evidências da relação entre o seu desenvolvimento e a obesidade. O mecanismo que os relaciona ainda não é completamente entendido. Entretanto é essencial a compreensão do tecido adiposo nas alterações metabólicas relacionadas à obesidade e ao câncer. Revisar a influência dos níveis séricos de leptina em pacientes com carcinoma hepatocelular. Trata-se de revisão bibliográfica baseada na metodologia do Instituto Cochrane; a busca de dados foi realizada na base de dados Science Direct, Scielo, Medline, Lilacs e Pubmed, empregando as seguintes descritores: hepatocellular carcinoma, leptin, adipokine.

  10. Hepatitis infections, aflatoxin and hepatocellular carcinoma

    The incidence rates of hepatocellular carcinoma (HCC show large geographic variations, globally reflecting the prevalence of two main aetiologic factors, hepatitis B (HBV and/or C (HCV virus infection and exposure to high levels of aflatoxin in the diet (Chen et al. 1997. The highest incidence rates are observed in regions where most of the population is exposed to both factors, such as in parts of eastern Asia and in sub-Saharan Africa (Parkin et al. 2001. These high incidences are consistent with the fact that HBV chronicity and exposure to aflatoxin have a multiplicative effect of risk for HCC. Depending on aetiology and geographic area, mutations in TP53 show striking differences in prevalence and pattern. In Europe and the US, where alcohol is a major risk factor in addition to viral infections, mutations occur in about 25% of HCC and show as much diversity in their type and codon position as in most other epithelial cancers. However, in high incidence areas such as Mozambique, Senegal, The Gambia (Africa and Qidong county (China, TP53 is mutated in over 50% of the cases and the vast majority of these mutations are a single missense, hotspot mutation at codon 249, AGG to AGT, resulting in the substitution of arginine into serine (249ser. This mutation is uncommon in regions where aflatoxin is not present at significant levels in the diet. In areas of intermediate exposure to aflatoxin, as for example in Thailand, the prevalence of the 249ser mutation is intermediate between high- and low-incidence areas. Thus, there is a dose-dependent relationship between exposure to aflatoxin, incidence of HCC and prevalence of 249ser mutation. Aflatoxins are toxic and carcinogenic metabolites produced by several varieties of molds, mainly Aspergillus flavus and Aspergillus parasiticum. These molds contaminate a wide range of traditional agricultural products in countries

    We performed 70 procedures of transarterial chemoembolization (TAE) through extrahepatic collateral vessels (n=27) or parasitic feeders (n=18) in 45 hepatocellular carcinoma patients. The collaterals developed after interruption of the hepatic artery due to repeated TAE (n=17), surgical ligation (n=7)and primary celiac occlusion (n=3). Radiologic findings suggest the existence of parasitic or collateral supply for hepatocellular carcinoma were 1) a focal defect of Lipiodol retention on CT or plain film after TAE via the hepatic artery, 2) dilated and tortuous vessels around the mass on angiography, 3) persistent elevation of the level of serum alpha-fetoprotein or continuous clinical symptoms in spite of sufficient devascularization of the tumor via the hepatic artery, and 4) radiological findings of direct invasion into adjacent organ. The sites of the catheter placement were the inferior phrenic artery(n=19), omental branches(n=16), periportal collaterals (n=6), pancreaticodenal arcade (n=3), gastroduodenal artery(n=3), internal mammary artery (n=2), intercosal artery (n=2), lateral thoracic artery (n=1), bronchial artery (n=1), and colic branches (n=1). Masses feeded by the inferior phrenic and chest wall collaterals were usually located at the dome area of the liver, and the omental and gastroduodenal collaterals developed in the masses located at the inferior tip of the liver. After TAE via collateral vessels, 37 patients underwent follow-up study. In 18 cases(48%), the tumor favorably responded to TAE. Specific complications of collateral TAE were epigastric soreness (n=10), severe shoulder pain (n=4), and embolization of the spinal artery during embolization through the intercostal artery (n=1). In conclusion, various extrahepatic collateals are important alternative or addition routes for effective chemoembolization in patients with advanced hepatoma, and early recognition of the parasitic supply and the effort to perform TAE via collaterals is very

    Rottlerin has been reported to exert its anti-tumor activity in various types of human cancers. However, the underlying molecular mechanism has not been fully elucidated. In the current study, we explored whether rottlerin exhibits its tumor suppressive function in hepatocellular carcinoma cells. Our MTT assay results showed that rottlerin inhibited cell growth in hepatocellular carcinoma cells. Moreover, we found that rottlerin induced cell apoptosis and caused cell cycle arrest at G1 phase. Furthermore, our wound healing assay result demonstrated that rottlerin retarded cell migration in hepatocellular carcinoma cells. Additionally, rottlerin suppressed cell migration and invasion. Notably, we found that rottlerin upregulated DDX3 expression and subsequently downregulated Cyclin D1 expression and increased p21 level. Importantly, down-regulation of DDX3 abrogated the rottlerin-mediated tumor suppressive function, whereas overexpression of DDX3 promoted the anti-tumor activity of rottlerin. Our study suggests that rottlerin exhibits its anti-cancer activity partly due to upregulation of DDX3 in hepatocellular carcinoma cells. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the clinical efficacy and survival rate of transarterial chemoembolization (TACE) alone or plus radiofrequency ablation (RFA) in patients with intermediate or advanced stage primary hepatocellular carcinoma (HCC). In this retrospective study, 467 cases received RFA or TACE plus RFA. Among them, 167 cases with strict clinical procedure (TACE alone or plus RFA) and complete follow-up data were included. Eighty-seven cases received TACE and 80 cases had TACE plus RFA between January 2000 and December 2006. Hierarchical analyses were performed using log-rank tests and survival curve was estimated by Kaplan-Meier method. A total of 167 patients received TACE alone or plus RFA for a follow-up period of 1 to 89 months. In the TACE alone group, the time-to-progression (TTP) was an average of 3.6 months. The median survival was 13 months, one-year survival rate 52.9%, three-year survival rate 11.5% and five-year survival rate 4.6%. In the TACE plus RFA group, the TTP time was an average of 10.8 months. The median survival time was 30 months, one-year survival rate 85.0%, three-year survival rate 45.0% and five-year survival rate 11.3%. In the TACE alone group, the median survival of intermediate stage HCC was 14 months, one-year survival rate 62.2%, three-year survival rate 13.3% and five-year survival rate 4.4%; In the TACE plus RFA group, the median survival of intermediate stage HCC was 14 months, one-year survival rate 90.1%, three-year survival rate 52.9% and five-year survival rate 13.7%. All differences of two groups has statistical significance (P advanced stage HCC, the median survival time was 12 months, one-year survival rate 35%, three-year survival rate 7.1% and five-year survival rate 0 in the TACE alone group versus 28 months, 62.1%, 24.1% and 6.9% in the TACE plus RFA group (P = 0.00).

    AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

    2003-01-01

    Objective: To study the helical CT dual-phase enhancement manifestation of the hypodense small hepatocellular carcinoma, and to evaluate its correlation with the histopathology. Methods: The CT signs and its histopathologic changes were analyzed in 25 cases with 27 hypodense lesions in helical CT dual-phase enhancement. All the lesions were confirmed as small hepatocellular carcinoma by operation and histopathology. Results: (1) On unenhanced scan, 16 lesions were with obscure borders and 11 lesions were with well-delineated borders. On enhanced scan, only 7 lesions were with obscure borders and the other 20 lesions were with well-delineated borders, and their contours were slightly irregular. (2) On unenhanced scan, 18 lesions showed homogeneous hypodensity and 9 lesions showed heterogeneous hypodensity. On enhanced scan, only 6 lesions showed homogeneous hypodensity and the other 21 lesions showed heterogeneous hypodensity with multiple flecks of more hypodense areas. Conclusion: The helical CT dual-phase enhancement characteristic manifestations of hypodense small hepatocellular carcinoma were as follows: the border of the lesion was obscure on unenhanced scan, however the border of the lesion became well-delineated and slightly irregular, and there were multiple flecks of more hypodense areas in the lesions after enhancement. This might be an important character in distinguishing hypodense small hepatocellular carcinoma from other hypodense diseases in the liver

  2. MicroRNA gene polymorphisms and environmental factors increase patient susceptibility to hepatocellular carcinoma.

    Yin-Hung Chu

    Full Text Available BACKGROUND: Micro RNAs (miRNAs are small RNA fragments that naturally exist in the human body. Through various physiological mechanisms, miRNAs can generate different functions for regulating RNA protein levels and balancing abnormalities. Abnormal miRNA expression has been reported to be highly related to several diseases and cancers. Single-nucleotide polymorphisms (SNPs in miRNAs have been reported to increase patient susceptibility and affect patient prognosis and survival. We adopted a case-control research design to verify the relationship between miRNAs and hepatocellular carcinoma. METHODOLOGY/PRINCIPAL FINDINGS: A total of 525 subjects, including 377 controls and 188 hepatocellular carcinoma patients, were selected. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP and real-time PCR were used to analyze miRNA146a (rs2910164, miRNA149 (rs2292832, miRNA196 (rs11614913, and miRNA499 (rs3746444 genetic polymorphisms between the control group and the case group. The results indicate that people who carry the rs3746444 CT or CC genotypes may have a significantly increased susceptibility to hepatocellular carcinoma (adjusted odds ratio [AOR] = 2.84, 95% confidence interval [CI] = 1.88-4.30. In addition, when combined with environmental risk factors, such as smoking and alcohol consumption, interaction effects were observed between gene polymorphisms and environmental factors (odds ratio [OR] = 4.69, 95% CI = 2.52-8.70; AOR = 3.38, 95% CI = 1.68-6.80. CONCLUSIONS: These results suggest that a significant association exists between miRNA499 SNPs and hepatocellular carcinoma. Gene-environment interactions of miRNA499 polymorphisms, smoking, and alcohol consumption might alter hepatocellular carcinoma susceptibility.

  3. Spinal cord compression secondary to bone metastases from hepatocellular carcinoma

    2006-01-01

    Bone metastases are rare in primary hepatocellular carcinoma (HCC). Spinal cord compression (SCC) due to bone metastases occur commonly in patients with lung and breast carcinomas, and metastatic HCC is an unusual cause of SCC. Spinal cord compression is an oncologic emergency and treatment delays can lead to irreversible consequences. Thus, the awareness that SCC could be a potential complication of bone metastases due to HCC is of significance in initiation of early treatment that can improve the quality of life and survival of the patients, if diagnosed earlier. This paper describes four cases of primary HCC with varied manifestations of SCC due to bone metastases. The first patient presented primarily with the symptoms of bone pains corresponding to the bone metastases sites rather than symptoms of associated hepatic pathology and eventually developed SCC. The second patient, diagnosed as having HCC, developed extradural SCC leading to paraplegia during the course of illness, for which he underwent emergency laminectomy with posterior fixation. The third patient developed SCC soon after the primary diagnosis and had to undergo emergency laminectomy. Post laminectomy he had good neurological recovery. The Fourth patient presented primarily with radicular pains rather than frank paraplegia as the first manifestation of SCC. PMID:16937544

    2018-05-01

    Background: The "meeting-in-the-middle" (MITM) is a principle to identify exposure biomarkers that are also predictors of disease. The MITM statistical framework was applied in a nested case-control study of hepatocellular carcinoma (HCC) within European Prospective Investigation into Cancer and Nutrition (EPIC), where healthy lifestyle index (HLI) variables were related to targeted serum metabolites. Methods: Lifestyle and targeted metabolomic data were available from 147 incident HCC cases and 147 matched controls. Partial least squares analysis related 7 lifestyle variables from a modified HLI to a set of 132 serum-measured metabolites and a liver function score. Mediation analysis evaluated whether metabolic profiles mediated the relationship between each lifestyle exposure and HCC risk. Results: Exposure-related metabolic signatures were identified. Particularly, the body mass index (BMI)-associated metabolic component was positively related to glutamic acid, tyrosine, PC aaC38:3, and liver function score and negatively to lysoPC aC17:0 and aC18:2. The lifetime alcohol-specific signature had negative loadings on sphingomyelins (SM C16:1, C18:1, SM(OH) C14:1, C16:1 and C22:2). Both exposures were associated with increased HCC with total effects (TE) = 1.23 (95% confidence interval = 0.93-1.62) and 1.40 (1.14-1.72), respectively, for BMI and alcohol consumption. Both metabolic signatures mediated the association between BMI and lifetime alcohol consumption and HCC with natural indirect effects, respectively, equal to 1.56 (1.24-1.96) and 1.09 (1.03-1.15), accounting for a proportion mediated of 100% and 24%. Conclusions: In a refined MITM framework, relevant metabolic signatures were identified as mediators in the relationship between lifestyle exposures and HCC risk. Impact: The understanding of the biological basis for the relationship between modifiable exposures and cancer would pave avenues for clinical and public health interventions on metabolic mediators

    Orthotopic liver transplantation is a curative treatment for hepatocellular carcinoma within Milan criteria, but these criteria preclude many patients from transplant candidacy. Recent studies have demonstrated that downstaging therapy can reduce tumor burden to meet conventional criteria. The present study reports a single-center experience with tumor downstaging and its effects on post-orthotopic liver transplantation outcomes. All patients with hepatocellular carcinoma who were evaluated by our multidisciplinary liver services team from 2012 to 2016 were identified (N = 214). Orthotopic liver transplantation candidates presenting outside of Milan criteria at initial radiographic diagnosis and/or an initial alpha-fetoprotein >400 ng/mL were categorized as at high risk for tumor recurrence and post-transplant mortality. Of the 214 patients newly diagnosed with hepatocellular carcinoma, 73 (34.1%) eventually underwent orthotopic liver transplantation. The majority of patients who did not undergo orthotopic liver transplantation were deceased or lost to follow-up (47.5%), with 14 of 141 (9.9%) currently listed for transplantation. Among transplanted patients, 21 of 73 (28.8%) were considered high-risk candidates. All 21 patients were downstaged to within Milan criteria with an alpha-fetoprotein hepatocellular carcinoma was higher but acceptable between downstaged high-risk and traditional candidates (9.5% vs 1.9%; P > .05) at a median follow-up period of 17 months. Downstaged high-risk candidates had a similar overall survival compared with those transplanted within Milan criteria (log-rank P > .05). In highly selected cases, patients with hepatocellular carcinoma outside of traditional criteria for orthotopic liver transplantation may undergo downstaging therapy in a multidisciplinary fashion with excellent post-transplant outcomes. These data support an aggressive downstaging approach for selected patients who would otherwise be deemed ineligible for

In this method, drugs containing x-Ray opaque factors–with high atomic numbers–are injected into the patient’s vein. After appropriate drug accumulation, about at least ten percent of the total injected amounts, 200kev. up to 300kev. of localized x-Ray beams is radiated to the site of the tumor. The Ethic Committee of Shahid Beheshti University of Medical Education and Health Services authorized the implementation of this new cancer treatment method, initially only on the group of patients who suffered from hepato-cellular carcinoma. Hepato cellular carcinoma is one of the most current malignancies of liver. In some cases, in addition to surgery, several approaches exist to come near the aim of predominating hepato-cellular carcinoma such as chemotherapy, current Radiation Therapy, Radio-Frequency application (RF, Trans-Artepical Chemo Embolization, (TACE, and Percutaneous Ethanol Injection (PEI. The effectiveness of the above-mentioned methods is about 10%-47%, applied alone or along side each other. Materials and methods: This study was a clinical-trial one. In this study, first, lipiodol (an x-ray opaque material with a high atomic number was transferred into the main vessel terminating to the tumor by angio-catheterization. Then,200kev. up to 250kev. of localized x-ray was radiated to the site of the tumor in one session. The drug volume was proportionally selected to the volume of the tumor, and the irradiation intensity was between 400 to 600cent.Gy. the beam energy absorption capacity of this drug is as times as

    Full Text Available Abstract Background More than 50% of the worldwide cases of hepatocellular carcinoma occur in China, and this malignancy currently represents the country's second leading cause of cancer death in cities and the leading cause in rural areas. Despite recent advances in the control and management of hepatocellular carcinoma within China, this disease remains a major health care issue. The global HCC BRIDGE study, designed to assess patterns of hepatocellular carcinoma therapy use and associated outcomes across real-world clinical practice, has recently been expanded as a national study in China, allowing a detailed analysis of hepatocellular carcinoma in this important country. Methods/Design The global HCC BRIDGE study is a multiregional longitudinal cohort trial including patients newly diagnosed with hepatocellular carcinoma between January 1, 2005, and June 30, 2011, who are receiving treatment for hepatocellular carcinoma via sites in the Asia-Pacific, European, and North American regions. The HCC BRIDGE China national study comprises the portion of the global HCC BRIDGE study conducted within mainland China. Patients will be followed from time of diagnosis of hepatocellular carcinoma (post-January 1, 2005 to time of death or December 31, 2011, whichever comes first. Data will be collected on demographic/clinical characteristics, relevant laboratory values, hepatocellular carcinoma/underlying liver disease treatment, tumor response, adverse events, hospitalizations, and overall survival. The primary study end point is overall survival; secondary end points are disease progression, treatment-limiting adverse events, and treatment failure. Results At the time of writing, 15 sites have selected for participation across all 7 traditional regions of China (North, North-East, East, South, South-West, North-West, and Central. The anticipated study population from the China national study is approximately 9000 patients. Discussion Findings from the

    Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, is associated with low survival. U.S. studies examining self-reported pesticide exposure in relation to HCC have demonstrated inconclusive results. We aimed to clarify the association between pesticide exposure and HCC by implementing a novel data linkage between Surveillance, Epidemiology, and End Results (SEER)-Medicare and California Pesticide Use Report (PUR) data using a geographic information system (GIS). Controls were frequency-matched to HCC cases diagnosed between 2000 and 2009 in California by year, age, race, sex, and duration of residence in California. Potential confounders were extracted from Medicare claims. From 1974 to 2008, pounds (1 pound represents 0.45 kg) of applied organophosphate, organochlorine, and carbamate pesticides provided in PURs were aggregated to the ZIP Code level using area weighting in a GIS. ZIP Code exposure estimates were linked to subjects using Medicare-provided ZIP Codes to calculate pesticide exposure. Agricultural residents were defined as living in ZIP Codes with a majority area intersecting agricultural land cover according to the 1992, 2001, and 2006 National Land Cover Database (NLCD) rasters. Multivariable conditional logistic regression was used to estimate the association between pesticide exposure and HCC. Among California residents of agriculturally intensive areas, previous annual ZIP Code-level exposure to over 14.53 kg/km(2) of organochlorine pesticides (75(th) percentile among controls) was associated with an increased risk of HCC after adjusting for liver disease and diabetes (adjusted odds ratio [OR] 1.87, 95% confidence interval [CI] 1.17, 2.99; p=0.0085). ZIP Code-level organochlorines were significantly associated with an increased risk of HCC among males (adjusted OR 2.76, 95% CI 1.58, 4.82; p=0.0004), but not associated with HCC among females (adjusted OR 0.83, 95% CI 0.35, 1.93; p=0.6600) (interaction p=0.0075).

    Although transcatheter arterial chemoembolization is one of the established treatments for hepatocellular carcinoma (HCC), it is difficult to treat HCCs with prominent arterioportal (AP) shunts because anticancer drugs and embolic materials migrate into the non-tumorous liver through the AP shunts and may cause liver infarction. We developed a novel method of balloon-assisted chemoembolization using a micro-balloon catheter alongside a microcatheter simultaneously inserted through a single 4.5-Fr guiding sheath, comprising proximal chemoembolization with distal arterial balloon occlusion. We applied this method to treat an HCC with a prominent distal AP shunt induced by previous proton beam therapy and achieved successful chemoembolization without non-tumorous liver infarction under temporal balloon occlusion of a distal AP shunt.

    Two patients in whom asymptomatic and small hepatocellular carcinomas (HCC) were detected by ..cap alpha..-fetoprotein (AFP) screening are reported. Both patients were hepatitis B surface antigen-positive. In the first patient, the tumour grew slowly and was resected more than 2 years after a significant elevation in serum AFP levels had been first detected and 13 months after hepatic angiography confirmed the presence of a vascular tumour. In the second patient, a small encapsulated HCC was diagnosed by AFP screening and hepatic imaging. Phosphorus 32 was used. The clinical course in these 2 patients illustrates that small, asymptomatic and encapsulated HCCs do occur in Southern African black hepatitis B carriers. Regular screening of patients at risk may be justified.

    1985-02-01

    The detectability of daughter nodules in 80 hepatocellular carcinomas was compared between CT assisted by Lipiodol Ultra Fluid (Lipiodol) infused via the hepatic artery and IHA (Infusion hepatic angiography). Lipiodol infused via the hepatic artery was selectively accumulated in the tumor vessels and the tumors and small daughter nodules appeared as markedly high density areas by CT. 18 cases in which the daughter nodules were detected were identified only by CT. Furthermore, in 38 cases CT demonstrated superior detectability of the daughthr nodules than IHA. In 15 cases the daughter nodules were newly detected in areas other than the invaded area where the primary tumor existed. This method is very effective in the diagnosis of daughter nodules of hepatocellular carcinoma. (author).

    Full Text Available We report a rare case of hepatocellular carcinoma in native liver in a case of biliary atresia. The patient was a 38-year-old female with three children who had an aggressive tumor, resulting in her subsequent death. We also review 14 reports, published previously in the English language medical literature, concerning hepatocellular carcinoma originating from native liver in biliary atresia cases and discuss the possible etiology, and propose more careful follow up for the patients with biliary atresia who suffer from repetitive cholangitis and/or experience the child delivery.

  13. FBX8 Acts as an Invasion and Metastasis Suppressor and Correlates with Poor Survival in Hepatocellular Carcinoma.

    Feifei Wang

    Full Text Available F-box only protein 8 (FBX8, a novel component of F-box proteins, is lost in several cancers and has been associated with invasiveness of cancer cells. However, its expression pattern and role in the progression of hepatocellular carcinoma remain unclear. This study investigated the prognostic significance of FBX8 in hepatocellular carcinoma samples and analyzed FBX8 function in hepatocellular carcinoma cells by gene manipulation.The expression of FBX8 was detected in 120 cases of clinical paraffin-embedded hepatocellular carcinoma tissues, 20 matched pairs of fresh tissues and five hepatocellular carcinoma cell lines by immunohistochemistry with clinicopathological analyses, real-time RT-PCR or Western blot. The correlation of FBX8 expression with cell proliferation and invasion in five HCC cell lines was analyzed. Moreover, loss of function and gain of function assays were performed to evaluate the effect of FBX8 on cell proliferation, motility, invasion in vitro and metastasis in vivo.We found that FBX8 was obviously down-regulated in HCC tissues and cell lines (P<0.05. The FBX8 down-regulation correlated significantly with poor prognosis, and FBX8 status was identified as an independent significant prognostic factor. Over-expression of FBX8 decreased proliferation, migration and invasion in HepG2 and 97H cells, while knock-down of FBX8 in 7721 cells showed the opposite effect. FBX8 negatively correlated with cell proliferation and invasion in 7701, M3, HepG2 and 97H cell lines. In vivo functional assays showed FBX8 suppressed tumor growth and pulmonary metastatic potential in mice. Our results indicate that down-regulation of FBX8 significantly correlates with invasion, metastasis and poor survival in hepatocellular carcinoma patients. It may be a useful biomarker for therapeutic strategy and control in hepatocellular carcinoma treatment.

    Detectability of a total of 125 foci in 84 cases with HCC was evaluated. All foci were surgically resected and confirmed histologically. Tumor size >=2.1 cm in diameter:each modality has the accuracy more than 90%, 2.0>=Tumor size>=1.1 cm:CT has the accuracy of 81%, US 56% and Angio 56% respectively. 1.0 cm>=Tumor size:CT shows the accuracy of 35%, US 5% and Angio 30%. Combined with CT, US and Angio in the lesions more than 1.1 cm in diameter, over all accuracy was 100%. Whereas, in the foci less than 1.0 cm, over all accuracy was only 45%, comparing with that of intraoperative US. 57%. Therefore, it was clarified to be very difficult to detect these small lesions, and a careful survey is needed. (author).

    Full Text Available Takamichi Murakami,1 Masakatsu Tsurusaki,1 Tomoko Hyodo,1 Yasuharu Imai2 1Department of Radiology, Kinki University Faculty of Medicine, 2Department of Hepatology and Gastroenterology, Ikeda Municipal Hospital, Osaka, Japan Abstract: The hemodynamics of a hepatocellular nodule is the most important imaging parameter used to characterize various hepatocellular nodules in liver cirrhosis, because sequential changes occur in the feeding vessels and hemodynamic status during hepatocarcinogenesis. Therefore, the imaging criteria for hepatocellular carcinoma (HCC are also usually based on vascular findings, eg, early arterial uptake followed by washout in the portal venous and equilibrium phases. Contrast-enhanced ultrasonography, dynamic multidetector-row computed tomography (MDCT, and dynamic magnetic resonance (MR imaging with gadopentetate dimeglumine (Gd-DTPA are useful for detecting hypervascular HCC on the basis of vascular criteria but are not as useful for hypovascular HCC. Contrast-enhanced MR imaging with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA, a hepatocyte-specific MR contrast agent, is superior to dynamic MDCT and dynamic MR imaging with Gd-DTPA in detecting both hypervascular and hypovascular HCC. Moreover, Gd-EOB-DTPA-enhanced MR imaging can display each histologically differentiated HCC as hypointense relative to the liver parenchyma. 18F-fluorodeoxyglucose positron emission tomography imaging might not be suitable for the screening and detection of HCC, given its lower diagnostic performance. However, this technique plays an important role in determining whether HCC has spread beyond the liver. Keywords: hepatocellular carcinoma, evaluation, imaging, clinical utility

    2008-01-01

    Objective: To analyze the imaging features of hepatocellular carcinoma(HCC) with bile duct tumor thrombi. Methods: Thirteen patients with bile duct tumor thrombi proved pathologically underwent imaging examination. MR and CT were performed in 3 cases, and 2 cases had CT only and 8 cases had MRI only. Ultrasonography(US) was performed in all 13 patients. The accuracy of bile duct tumor thrombi detection was compared between US, CT and MRI with Fisher test. Results: Liver tumors and bile duct tumor thrombi were demonstrated in all patients on CT or MRI. Presence of intraluminal soft tissue mass was found in four of five cases on CT, and mild enhancement of the intraluminal mass in the arterial phase was noted, dilated bile duct distal to tumor thrombi was detected in all five patients. Eleven Tumor thrombi showed slight low signal intensity on T 1 WI, slight high signal intensity on T 2 WI, and mild to moderate contrast enhancement on the contrast-enhanced MR images. The MRCP findings of tumor thrombi were as follows: interruption, stricture of the bile ducts or irregular filling defect in the bile ducts with dilated intrahepatic ducts, bile duet was abruptly interrupted or showed a 'rat-tail' stricture (n=5); the common bile duct was filled with tumor thrombi, intrahepatic bile duct dilatation and missing common bile duct was noted on MRCP (n=2). Bile duct tumor thrombi were correctly diagnosed in 7 cases on US, and 12 cases on CT or MRI. Six cases were misdiagnosed or miss-diagnosed on US, and 4 cases were misdiagnosed on CT or MRI. There was no significant difference between US and CT/MRI in diagnosis of bile duct tumor thrombi (P=0.270). Conclusion: CT or MR imaging is useful for the diagnosis of HCC with biliary tumor thrombi and for evaluating the extension of thrombi. (authors)

  17. Molecular pathogenesis of hepatocellular carcinoma and impact of therapeutic advances

    2016-01-01

    Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality and has an increasing incidence worldwide. HCC can be induced by multiple etiologies, is influenced by many risk factors, and has a complex pathogenesis. Furthermore, HCCs exhibit substantial heterogeneity, which compounds the difficulties in developing effective therapies against this highly lethal cancer. With advances in cancer biology and molecular and genetic profiling, a number of different mechanisms involved in the development and progression of HCC have been identified. Despite the advances in this area, the molecular pathogenesis of hepatocellular carcinoma is still not completely understood. This review aims to elaborate our current understanding of the most relevant genetic alterations and molecular pathways involved in the development and progression of HCC, and anticipate the potential impact of future advances on therapeutic drug development.

  18. CTP synthase forms the cytoophidium in human hepatocellular carcinoma.

    Chang, Chia-Chun; Jeng, Yung-Ming; Peng, Min; Keppeke, Gerson Dierley; Sung, Li-Ying; Liu, Ji-Long

    2017-12-15

    CTP synthase (CTPS) can aggregate into an intracellular macrostructure, the cytoophidium, in various organisms including human cells. Previous studies have shown that assembly of human CTPS cytoophidia may be correlated with the cellular metabolic status, and is able to promote the activity of CTPS. A correlation between the cytoophidium and cancer metabolism has been proposed but not yet been revealed. In the current study we provide clear evidence of the presence of CTPS cytoophidia in various human cancers and some non-cancerous tissues. Moreover, among 203 tissue samples of hepatocellular carcinoma, 56 (28%) samples exhibited many cytoophidia, whereas no cytoophidia were detected in adjacent non-cancerous hepatocytes for all samples. Our findings suggest that the CTPS cytoophidium may participate in the adaptive metabolism of human hepatocellular carcinoma. Copyright © 2017. Published by Elsevier Inc.

Despite considerable knowledge about it's scope and nature this malignancy remains incurable. This manuscript reviews the epidemiology of this cancer, its pathogenesis, risk factors, potential prevention, surveillance, treatment, and the oncology nurses' role relative to this malignancy. A literature search from the past decade was performed using the PubMed and CINAHL databases using the search terms “hepatocellular carcinoma,” “Asia,” and “nursing issues”. Themes such as etiology, prevention, treatment, and prognosis were included in this synthesis which has particular relevance to oncology nurses within the Asia-Pacific region.

  20. Serological diagnosis of hepatocellular carcinoma: challenges and opportunities

    LU Fengmin

    2017-07-01

    Full Text Available Serological markers have the features of noninvasiveness and simple operation and thus have become a research hotspot in the diagnosis of hepatocellular carcinoma. This article briefly introduces the role of the conventional serological marker alpha-fetoprotein (AFP in assisting the diagnosis and predicting the prognosis of HBV-related liver cancer, as well as the clinical value of new markers such as alpha-fetoprotein-L3 and abnormal prothrombin/des-γ-carboxy prothrombin. Based on literature review, the possibility of serum Golgi protein 73 used for laboratory auxiliary diagnosis of hepatocellular carcinoma has been denied. The results of the author′s experiment suggest that serum GP73 measurement can be used as a laboratory diagnostic index for progressive liver fibrosis and liver cirrhosis.

    To determine efficacy of intrahepatic absolute alcohol injection in researchable hepatocellular carcinoma. A randomized, controlled, experimental and interventional clinical trial. Gastroenterology Department, PGMI, Hayatabad Medical Complex, Peshawar during the period from June, 1998 to June, 2000. Thirty patients were treated by percutaneous, intrahepatic absolute alcohol injection sin repeated sessions, 33 patients were not given or treated with alcohol to serve as control. Both the groups were comparable for age, sex and other baseline characteristics. Absolute alcohol therapy significantly improved quality of life of patients, reduced the tumor size and mortality as well as showed significantly better results regarding survival (P< 0.05) than the patients of control group. We conclude that absolute alcohol is a beneficial and safe palliative treatment measure in advanced hepatocellular carcinoma (HCC). (author)

  2. Simple Sugar Intake and Hepatocellular Carcinoma: Epidemiological and Mechanistic Insight

    Juan Carlos Laguna

    2014-12-01

    Full Text Available Sugar intake has dramatically increased during the last few decades. Specifically, there has been a clear trend towards higher consumption of fructose and high fructose corn syrup, which are the most common added sugars in processed food, soft drinks and other sweetened beverages. Although still controversial, this rising trend in simple sugar consumption has been positively associated with weight gain and obesity, insulin resistance and type 2 diabetes mellitus and non-alcoholic fatty liver disease. Interestingly, all of these metabolic alterations have also been related to the development of hepatocellular carcinoma. The purpose of this review is to discuss the evidence coming from epidemiological studies and data from animal models relating the consumption of simple sugars, and specifically fructose, with an increased risk of hepatocellular carcinoma and to gain insight into the putative molecular mechanisms involved.

    2012-09-01

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

    1993-01-01

    Transcatheter arterial chemoembolization(TACE) is an imperative method for the management of inoperable hepatocellular carcinoma(HCC). It is well known that primary HCC frequently invades the portal venous system and forms a tumor thrombus obstructing the portal blood flow which makes unfavorable prognosis of patient. We retrospectively reviewed 58 patients who reviewed TACE(minimum 3 times) of HCC invading into portal venous system. Group 1(n=29) which showed peripheral portal vein invasion had better clinical and laboratory response. Group 2(n=17) which showed first order portal branch invasion had similar response to Group 3(n=12), which had main portal invasion. Group 1 showed no difference in survival time between TAC and TACE, but, in Group 2 and 3, embolization with chemotherapy made longer survival than chemotherapy only. Clinical level of AFP was meaningful in Group 1 and 2 as decreasing value. Our results provides that careful selection of TAE and case by case Coil/Gelfoam embolization can improve the mean survival and clinical response when HCC evidently invades portal venous system

    Full Text Available Since the 1970s, the epidemic of hepatocellular carcinoma (HCC has spread beyond the Eastern Asian predominance and has been increasing in Northern hemisphere, especially in the United States (US and Western Europe. It occurs more commonly in males in the fourth and fifth decades of life. Among all cancers, HCC is one of the fastest growing causes of death in the US and poses a significant economic burden on healthcare. Chronic liver disease due to hepatitis B virus or hepatitis C virus and alcohol accounts for the majority of HCC cases. Incidence of nonalcoholic fatty liver disease has been on the risem and it has also been associated with the development of HCC. Its pathogenesis varies based on the underlying etiological factor although majority of cases develop in the setting of background cirrhosis. Carcinogenesis of HCC includes angiogenesis, chronic inflammation, and tumor macroenvironment and microenvironment. There is a significant role of both intrinsic genetic risk factors and extrinsic influences such as alcohol or viral infections that lead to the development of HCC. Understanding its etiopathogenesis helps select appropriate diagnostic tests and treatments.

  7. Evaluation of arterial embolization therapy of hepatocellular carcinoma by computed tomography

    Ohishi, H; Ohue, S; Ide, K [Nara Medical Univ., Kashihara (Japan)

    1981-11-01

    The therapeutic effect of arterial embolization performed to 18 patients with hepatocellular carcinoma was evaluated by means of computed tomography (CT). 1) After embolization, the tumor was observed to have been reduced in size in all the cases. The relative attenuation coefficients of the tumor region to surrounding liver tissue was decreased at initial stage after arterial embolization, however, it showed a tendency of more elevation than the initial stage in the cases performed follow-up CT. The decrease of the attenuation values at the initial stage suggests the ischemic necrosis, while its elevation is considered attributable to subsequent histologic change and tumor shrinkage. 2) The follow-up CT examination after the arterial embolization on hepatocellular carcinoma provides significant facility for evaluation of its effectiveness and judgement of the time for the repeat arterial embolization.

    2001-01-01

    In this study, it was investigated whether dose response relation existed or not in local radiotherapy for primary hepatocellular carcinoma. From January 1992 to March 2000, 158 patients were included in present study. Exclusion criteria included the presence of extrahepatic metastasis, liver cirrhosis of Child's class C, tumors occupying more than two thirds of the entire liver, and performance status on the ECOG scale of more than 3. Radiotherapy was given to the field including tumor with generous margin using 6, 10-MV X-ray. Mean tumor dose was 48.2±7.9 Gy in daily 1.8 Gy fractions. Tumor response was based on diagnostic radiologic examinations such as CT scan, MR imaging, hepatic artery angiography at 4-8 weeks following completion of treatment. Statistical analysis was done to investigate the existence of dose response relationship of local radiotherapy when it was applied to the treatment of primary hepatocellular carcinoma. An objective response was observed in 106 of 158 patients, giving a response rate of 67. 1%. Statistical analysis revealed that total dose was the most significant factor in relation to tumor response when local radiotherapy was applied to the treatment of primary hepatocellular carcinoma. Only 29.2% showed objective response in patients treated with dose less than 40 Gy, while 68.6% and 77.1 % showed major response in patients with 40-50 Gy and more than 50 Gy, respectively. Child-Pugh classification was significant factor in the development of ascites, overt radiation induced liver disease and gastroenteritis. Radiation dose was an important factor for development of radiation induced gastroduodenal ulcer. Present study showed the existence of dose response relationship in local radiotherapy for primary hepatocellular carcinoma. Only radiotherapy dose was a significant factor to predict the objective response. Further study is required to predict the maximal tolerance dose in consideration of liver function and non-irradiated liver

    Full Text Available Hemoperitoneum due to spontaneous rupture of hepatocellular carcinoma is a life-threatening and rare condition in western countries with an incidence of less than 3% because of early detection of cirrhosis and neoplasm. Here, we describe a case of a 66-year-old male patient with altered mental status with hemorrhagic shock. Computed tomography scan of abdomen revealed hemoperitoneum and mass in liver. Patient underwent resection of liver tumor and biopsy revealed multinodular hepatocellular carcinoma. A high degree of suspicion is required where severe anemia and hemoperitoneum can be a first presentation for hepatocellular carcinoma especially in patients with chronic hepatitis C infection. Early diagnosis is crucial since mortality rates remain high for untreated cases.

    2008-03-01

    Full Text Available Abstract Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma in vitro. In a phase II trial, we investigated safety and efficacy including selection criteria for best response in advanced or metastasised hepatocellular carcinoma. Methods 44 patients (84 % male, median age 69 years not suitable or refractory to conventional therapy received thymostimulin 75 mg subcutaneously five times per week for a median of 8.2 months until progression or complete response. 3/44 patients were secondarily accessible to local ablation or chemoembolisation. Primary endpoint was overall survival, secondary endpoint tumor response or progression-free survival. A multivariate Cox's regression model was used to identify variables affecting survival. Results Median survival was 11.5 months (95% CI 7.9–15.0 with a 1-, 2- and 3-year survival of 50%, 23% and 9%. In the univariate analysis, a low Child-Pugh-score (p = 0.01, a low score in the Okuda- and CLIP-classification (p Conclusion Outcome in our study rather depended on liver function and intrahepatic tumor growth (presence of liver cirrhosis and Okuda stage in addition to response to thymostimulin, while an invasive HCC phenotype had no influence in the multivariate analysis. Thymostimulin could therefore be considered a safe and promising candidate for palliative treatment in a selected target population with advanced hepatocellular carcinoma, in particular as component of a multimodal therapy concept.

    Local treatment for hepatocellular carcinoma (HCC) has been widely used in clinical practice due to its minimal invasiveness and high rate of cure. Percutaneous radiofrequency ablation (RFA) is widely used because its treatment effectiveness. However, some serious complications can arise from percutaneous RFA. We present here a rare case of hemorrhagic cardiac tamponade secondary to an anterior cardiac vein (right marginal vein) injury during RFA for treatment of HCC.

  16. Hepatocellular carcinoma: illustrated guide to systematic radiologic diagnosis and staging according to guidelines of the American Association for the Study of Liver Diseases.

    McEvoy, Sinead H

    2013-10-01

    Hepatocellular carcinoma is a malignancy that predominantly occurs in the setting of cirrhosis. Its incidence is rising worldwide. Hepatocellular carcinoma differs from most malignancies because it is commonly diagnosed on the basis of imaging features alone, without histologic confirmation. The guidelines from the American Association for the Study of Liver Diseases (AASLD) are a leading statement for the diagnosis and staging of hepatocellular carcinoma, and they have recently been updated, incorporating several important changes. AASLD advocates the use of the Barcelona Clinic Liver Cancer (BCLC) staging system, which combines validated imaging and clinical predictors of survival to determine stage and which links staging with treatment options. Each stage of the BCLC system is outlined clearly, with emphasis on case examples. Focal liver lesions identified at ultrasonographic surveillance in patients with cirrhosis require further investigation. Lesions larger than 1 cm should be assessed with multiphasic computed tomography or magnetic resonance imaging. Use of proper equipment and protocols is essential. Lesions larger than 1 cm can be diagnosed as hepatocellular carcinoma from a single study if the characteristic dynamic perfusion pattern of arterial hyperenhancement and venous or delayed phase washout is demonstrated. If the imaging characteristics of hepatocellular carcinoma are not met, the alternate modality should be performed. Biopsy should be used if neither modality is diagnostic of hepatocellular carcinoma. Once the diagnosis has been made, the cancer should be assigned a BCLC stage, which will help determine suitable treatment options. Radiologists require a systematic approach to diagnose and stage hepatocellular carcinoma with appropriate accuracy and precision.

    Detection of thrombus is usually an incidental finding on fluorodeoxyglucose positron emission tomography/computed tomography studies. Nevertheless this is an important finding in terms of disease prognostication and in planning the treatment strategy. We herein report a case of a 50-years-old male, a diagnosed case of hepatocellular carcinoma with extensive hypermetabolic thrombus involving the entire portal venous system. (author)

  18. Targeting hepatocellular carcinoma: what did we discover so far?

    Ana Filipa Brito

    2016-10-01

    Full Text Available Hepatocellular carcinoma (HCC is increasingly considered an issue of global importance. Its rates of incidence and mortality have been markedly increasing over the last decades. Among risk factors, some should be highlighted, namely the infections by hepatitis B and C virus, as well as clinical cases of cirrhosis. HCC is characterized as asymptomatic disease in the initial stages which most often leads to a late diagnosis. At molecular and genetic level HCC represents a highly complex tumor entity, including a wide variety of mutations, thus accounting for different mechanisms of resistance towards therapeutic approaches. In particular, mutations of the TP53 gene, as well as a deregulation between the expression of pro- and anti-apoptotic proteins of the BCL-2 family are observed. Regarding treatment modalities, surgical procedures offer the best chance of cure, however, due to a late diagnosis, most of concerned patients cannot be subjected to them. Chemotherapy and radiotherapy are also ineffective, and currently, the treatment with sorafenib is the most commonly used systemic therapy although it can only increase the patient survival for some months. In this sense, a quick and accurate investigation is of utmost importance in order to develop ways of early diagnosis as well as new therapies for HCC.

    2016-12-01

    Combined liver and inferior vena cava (IVC) resection followed by IVC and/or hepatic vein reconstruction (HVR) is a curative operation for selected patients with hepatocellular carcinoma (HCC) invading the hepatocaval confluence. The present study aimed to elucidate the prognostic factors for patients with HCC invading the hepatocaval confluence. Forty-two consecutive patients underwent hepatectomy, combined with IVC replacement and/or HVR for HCC between January 2009 and December 2014 were included in this study. The cases were divided into three groups based on the surgical approaches of HVR: group 1 (n=13), tumor invaded the hepatocaval confluence but with one or two hepatic veins intact in the residual liver, thus only the replacement of IVC, not HVR; group 2 (n=23), the hepatic vein of the residual liver was also partially invaded, and the hepatic vein defect was repaired with patches locally; group 3 (n=6), three hepatic veins at the hepatocaval confluence were infiltrated, and the hepatic vein remnant was re-implanted onto the side of the tube graft. The patient characteristics, intra- and postoperative results, and long-term overall survival were compared among the three groups. The survival-related factors were analyzed by univariate and multivariate analysis. The group 1 had higher preoperative alpha-fetoprotein level (PHVR (PHVR (group 1). HVR was one of the unfavorable prognostic factors of overall survival.

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

  1. Hepatitis B Virus Infection, Genetic Susceptibility and Hepatocellular Carcinoma

    2015-12-01

    Full Text Available Liver cancer is a sever cancer burden in the world, especially in developing countries. Its late diagnosis and high mortality rate urges early prediction. Hepatocellular carcinoma (HCC is the major histopathological type of liver cancer. Chronic infection with hepatitis B virus (HBV is a well-established risk factor for HCC. On one side, HBV sequence variation may influence the outcome of HBV infection and the development of HCC. At least ten HBV genotypes (A to J are identified. Several HBV genotypes and mutations in pre-S and pre-core/core promoter regions are closely associated with HCC pathogenesis, and have been regarded as biomarkers to predict the occurrence of HCC. On the other side, only a small fraction of chronic hepatitis B patients developed HCC, and some HCC cases were diagnosed with no known predisposing risk factors, suggesting host genetic variations may also play important roles in the carcinogenesis. In this review, we summarized current findings of HBV genotypes and mutations, host genetic variations and their interactions involved in HCC carcinogenesis. Understanding the key viral and host genetic variations is essential for generating effective predictive biomarkers for HCC development.

    Background Our previous investigations have shown that the variants of X-ray repair complementing 4 (XRCC4) may be involved in hepatocellular carcinoma (hepatocarcinoma) tumorigenesis. This study aimed to investigate the possible prognostic significance of XRCC4 expression for hepatocarcinoma patients and possible value for the selection of transarterial chemoembolization (TACE) treatment. Materials and Methods We conducted a hospital-based retrospective analysis (including 421 hepatocarcinoma cases) to analyze the effects of XRCC4 on hepatocarcinoma prognosis and TACE. The levels of XRCC4 expression were tested using immunohistochemistry. The sensitivity of cancer cells to anti-cancer drug doxorubicin was evaluated using the half-maximal inhibitory concentration (IC50). Results XRCC4 expression was significantly correlated with pathological features including tumor stage, liver cirrhosis, and micro-vessel density. XRCC4 expression was an independent prognostic factor of hepatocarcinoma, and TACE treatments had no effects on prognosis of hepatocarcinoma patients with high XRCC4 expression. More intriguingly, TACE improved the prognosis of hepatocarcinoma patients with low XRCC4 expression. Functionally, XRCC4 overexpression increased while XRCC4 knockdown reduced the IC50 of cancer cells to doxorubicin. Conclusions These results suggest that XRCC4 may be an independent prognostic factor for hepatocarcinoma patients, and that decreasing XRCC4 expression may be beneficial for post-operative adjuvant TACE treatment in hepatocarcinoma.

    2010-08-01

    Full Text Available Hepatocellular carcinoma (HCC shows many pathological features, and it varies architecturally and cytologically. There have been many reports and discussions of the morphological features of HCC. A 63-year-old man was found to have a solitary tumor in liver segment 7 that was diagnosed as HCC. A partial resection of liver segment 7 was performed. Microscopically, the tumor lesion showed a moderately differentiated HCC. There was also a lesion with foamy histiocyte-like cells corresponding to the white lesion in the face of the cut tumor. Immunohistochemical staining showed that they were negative for CD68, S-100, vimentin, and HMB-45. The cytoplasm itself was negative on periodic acid Schiff (PAS and Sudan staining. Without immunohistological analysis, it is difficult to distinguish this HCC variant from clear cell carcinoma or metastases of renal cell carcinoma. It is important to recognize this type as a specific cytological variant of HCC that requires confirmation by immunohistochemistry. This report describes the case of a patient with a morphologically distinctive pattern of HCC with prominent cell cytoplasm that had a foamy histiocyte-like appearance. To the best of our knowledge, this is the first report of this HCC variant.

    Full text: Introduction: Hepatocellular adenoma is a benign hepatic tumor identified mainly in women during fertility age, with estimated incidence of 4/1000 inhabitants. It is usually unique, well circumscribed, with or without a capsule, size varying from 1 to 30 cm, with possible central areas of necrosis and hemorrhage. Case Report: A 37-year-old female patient presenting with no comorbities, use of hormonal birth control pills for 18 years, a condition of reduction in the consistency of feces, increase in number of daily defecations, abdominal cramps, and a stuffed sensation after meals for two years. A palpable abdominal mass extending from the right hypochondriac to the right iliac fossa was noticed four months ago. A computerized tomography (CT) showed an extensive hepatic mass on the right which was considered, within the diagnostic hypotheses, hepatic adenomatosis, without ruling out secondary lesions. A hepatic scintillography with {sup 99m}Tc-DISIDA showed an extensive exophytic area from segment V to the right iliac fossa with arterialized blood flow and hepatocytic activity, as well as a hepatic nodule in segment VII with hepatocytic activity consistent with the hepatic adenomas hypothesis. The biopsy confirmed the hepatic adenoma diagnosis and the patient was submitted to a partial hepatectomy and cholecystectomy with good clinical evolution. Conclusion: Nuclear Medicine may supplement the assessment of hepatic nodules, including giant masses, thus suggesting new hypotheses and direction to therapeutic conduct. (author)

    Full Text Available Abstract Background Glucose regulated protein 78 (Grp78 is involved in the invasion and metastasis in many human cancers including gastric cancer, breast cancer, prostate cancer. But the role of Grp78 in the invasion of human hepatocellular carcinoma has not been reported. In this article, we examined if Grp78 was associated with the invasion of hepatocellular carcinoma and explored the possible underlying mechanism. Methods The Grp78 and FAK expression levels in 44 patients with hepatocellular carcinoma were examined using immunohistochemistry. Grp78 overexpressing SMMC7721 cells were established by pcDNA3.1 (+-Grp78 transfection and screened by G418. Grp78 and FAK levels in Grp78 overexpressing cells were down-regulated by siRNA transfection. The invasion status of tumor cells was evaluated by transwell assay in vitro, and chick embryo metastasis model in vivo. Cell spreading was determined by cell spreading assay, and quantitatively measured by Orisis software HUG. Grp78, pY397 FAK, pY576/577 FAK and FAK levels were detected by western blot. RhoA activity was detected by GST pulldown assay. The distribution of actin cytoskeleton was observed by fluorescent staining. Results Grp78 expression levels in 44 patients with hepatocellular carcinoma were negatively correlated with tumor grading, and positively correlated with portal invasion and intra-hepatic invasion. Overexpression of Grp78 in SMMC7721 cells promoted the invasion of cancer cells in vitro and in vivo, and this increase in tumor cell invasion was blocked by Grp78 siRNA knockdown. Our results also revealed that overexpression of Grp78 in SMMC7721 cells accelerated the process of cell spreading and promoted lamellipodia formation. Further analysis showed that overexpression of Grp78 in SMMC7721 cells increased pY397 and pY576/577 levels of FAK. Grp78 siRNA knockdown decreased FAK activation and activity. Our results also revealed that Grp78 overexpression in SMMC7721 cells decreased

    Hook1 is a member of the hook family of coiled-coil proteins, which is recently found to be associated with malignant tumors. However, its biological function in hepatocellular carcinoma is yet unknown. Here, we evaluated the Hook1 levels in human hepatocellular carcinoma samples and matched peritumoral tissues by real-time polymerase chain reaction. Small interfering RNA knockdown and a transforming growth factor-β-induced epithelial-mesenchymal transition model were employed to investigate the biological effects of Hook1 in hepatocellular carcinoma. Our results indicated that Hook1 levels were significantly lower in hepatocellular carcinoma tissues than in the peritumoral tissues. In addition, Hook1 expression was significantly associated with hepatocellular carcinoma malignancy. Hook1 was downregulated after transforming growth factor-β-induced epithelial-mesenchymal transition. Moreover, Hook1 knockdown promoted epithelial-mesenchymal transition and attenuated the sensitivity of hepatocellular carcinoma cells to doxorubicin. In summary, our results indicate that downregulation of Hook1 plays a pivotal role in hepatocellular carcinoma progression via epithelial-mesenchymal transition. Hook1 may be used as a novel marker and therapeutic molecular target in hepatocellular carcinoma.

    Patients with hereditary tyrosinemia type 1 have an elevated risk of developing hepatocellular carcinoma, especially if initiation of treatment with 2-(2-nitro-4-trifluoro-methylbenzoyl)-1,3-cyclohexanedione is delayed. Hepatocellular carcinoma can usually be suspected when there are increased

  9. Circulating predictive and diagnostic biomarkers for hepatitis B virus-associated hepatocellular carcinoma

    Van Hees, Stijn; Michielsen, Peter; Vanwolleghem, Thomas

    2016-01-01

    Chronic hepatitis B virus (HBV) infected patients have an almost 100-fold increased risk to develop hepatocellular carcinoma (HCC). HCC is the fifth most common and third most deadly cancer worldwide. Up to 50% of newly diagnosed HCC cases are attributed to HBV infection. Early detection improves survival and can be achieved through regular screening. Six-monthly abdominal ultrasound, either alone or in combination with alpha-fetoprotein serum levels, has been widely endorsed for this purpose. Both techniques however yield limited diagnostic accuracy, which is not improved when they are combined. Alternative circulating or histological markers to predict or diagnose HCC are therefore urgently needed. Recent advances in systems biology technologies have enabled the identification of several new putative circulating biomarkers. Although results from studies assessing combinations of these biomarkers are promising, evidence for their clinical utility remains low. In addition, most of the studies conducted so far show limitations in design. Attention must be paid for instance to different ethnicities and different etiologies when studying biomarkers for hepatocellular carcinoma. This review provides an overview on the current understandings and recent progress in the field of diagnostic and predictive circulating biomarkers for hepatocellular carcinoma in chronically infected HBV patients and discusses the future prospects.

  10. Usefulness of Pure Laparoscopic Hepatectomy for Hepatocellular Carcinoma in a Severely Cirrhotic Patient

    Isamu Hosokawa

    2013-07-01

    Full Text Available The number of patients undergoing laparoscopic hepatectomy has rapidly increased in recent years, and indications for this procedure are gradually expanding. Pure laparoscopic hepatectomy is reportedly useful in cases with severe liver cirrhosis. A 55-year-old woman under observation for liver cirrhosis was found to have hepatocellular carcinoma in liver segment III and was referred to our hospital for surgery. The tumor was located in the edge of liver segment III, where percutaneous ablation therapy was unsuitable. Since her hepatic functional reserve was poor, pure laparoscopic partial hepatectomy was performed. The postoperative course was favorable, with no ascites retention, edema or weight gain. The greatest advantage of pure laparoscopic hepatectomy for hepatocellular carcinoma with concomitant liver cirrhosis is that postoperative ascites retention is minimal, meaning that there is little risk of water-electrolyte imbalance associated with ascites retention or hypoproteinemia. This is believed to be because the abdominal incision is small and mobilization of the liver is minimized, reducing the destruction of the routes of collateral lymph flow and blood flow generated in patients with liver cirrhosis. Pure laparoscopic hepatectomy may be a treatment choice for patients with hepatocellular carcinoma and concomitant severe liver cirrhosis.

  11. Intraparenchymal Hemorrhage due to Brain Metastasis of Hepatocellular Carcinoma

    Rafael Sartori Balbinot

    2017-09-01

    Full Text Available Although extrahepatic metastases from hepatocellular carcinoma (HCC are present in only 5–15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma. After admission, cranial computed tomography revealed an intraparenchymal hemorrhage area with surrounding edema in the right frontal lobe. An angioresonance requested showed a large extra-axial mass lesion located in the right frontal region with well-defined contours and predominantly hypointense signal on T2 sequence. At first, the radiological findings suggested meningioma as the first diagnostic hypothesis. However, the patient underwent surgery. The tumor was completely removed, and the morphological and immunohistochemical findings were consistent with metastatic hepatocarcinoma associated with meningioma. In postoperative care, the patient did not recover from the left hemiparesis and manifested Broca’s aphasia. He had a survival time of 24 weeks, presenting acute liver failure as his cause of death. There is a lack of evidence supporting a specific management of patients with brain metastasis from HCC. Furthermore, there are no studies that evaluate different modalities of therapeutics in brain metastasis of HCC due to the rarity of this condition. Therefore, management must be individualized depending on probable prognostic factors in these patients.

    Cryptogenic hepatocellular carcinoma (HCC) is thought to arise due to non-alcoholic fatty liver disease (NAFLD). This study investigated the prevalence, clinical features, and outcomes of cryptogenic HCC and compared them with those of HCC related to hepatitis B virus infection (HBV-HCC), hepatitis C virus infection (HCV-HCC), and alcohol (ALC-HCC) in Korea. The clinical features, treatment modalities, and survival data for 480 patients with HCC consecutively enrolled from January 2003 to June 2012 were analyzed. Computed tomography images were used to measure the visceral fat area (VFA) and liver-spleen density ratio. Cryptogenic HCC accounted for 6.8% of all HCC cases, whereas HBV-HCC, HCV-HCC, and ALC-HCC accounted for 62.7%, 13.5%, and 10.7% of HCC cases, respectively. The cryptogenic HCC group was characterized by older age, a low proportion of male patients, a high proportion of patients with metabolic syndrome or single nodular presentation, and a low proportion of patients with portal vein invasion compared to the viral-HCC and ALC-HCC groups. However, Child Pugh classes, tumor stages, and overall survival rates of cryptogenic HCC patients were similar to those of patients with HCC of other etiologies. VFA in cryptogenic HCC patients was significantly higher than that in viral-HCC patients, but similar to that in ALC-HCC patients. The liver-spleen density ratio did not vary according to HCC etiology. Cryptogenic HCC accounts for approximately 7% of HCC cases in Korea, associated with an older age at diagnosis, more frequent occurrence of metabolic syndrome, and less aggressive tumor characteristics, but similar survival compared to viral-HCC or ALC-HCC. Based on VFA and the liver-to-spleen density ratio, cryptogenic HCC may be burnt-out NAFLD in which visceral fat remains but liver fat is depleted

    Differential diagnosis between hepatocellular carcinoma and metastatic hepatic tumor was attempted using dynamic CT scanning. Homogeneous and patchy types were peculiar to hepatocellular carcinoma, and ring-like type to metastatic hepatic tumor. However, with no enhancement, hepatocellular carcinoma could not be denied. Hepatocellular carcinoma was characterized by the enhancement shown on the early stage of dynamic CT. Ring enhancement was not visualized on dynamic CT but visualized on conventional contrast enhanced CT in hepatocellular carcinomas; it was visualized on conventional contrast enhanced CT and on dynamic CT in metastatic hepatic tumors.

    Unresectable hepatocellular carcinoma is extremely difficult to treat. TheraSphere consists of yttrium-90 (a pure beta emitter) microspheres, which are injected into the hepatic arteries. This article reviews the safety and survival of patients with hepatocellular carcinoma who were treated with yttrium-90 microspheres. Eighty patients were selected from a database of 108 yttrium-90 microsphere-treated patients and were staged by using Child-Pugh, Okuda, and Cancer of the Liver Italian Program scoring systems. Patients were treated with local, regional, and whole-liver approaches. Survival from first treatment was analyzed with Kaplan-Meier and Cox regression methods. Adverse events and complications of treatment were coded by using the Southwest Oncology Group toxicity scoring system. Patients received liver doses ranging from 47 to 270 Gy. Thirty-two patients (40%) received more than 1 treatment. Survival correlated with pretreatment Cancer of the Liver Italian Program scores ( P = .002), as well as with the individual Cancer of the Liver Italian Program components, Child-Pugh class, alpha-fetoprotein levels, and percentage of tumor replacement. Patients classified as Okuda stage I (n = 54) and II (n = 26) had median survival durations and 1-year survival rates of 628 days and 63%, and 384 days and 51%, respectively ( P = .02). One patient died of liver failure judged as possibly related to treatment. Thus, in selected patients with hepatocellular carcinoma, yttrium-90 microsphere treatment is safe and well tolerated. On the basis of these results, a randomized controlled trial is warranted comparing yttrium-90 microsphere treatment with transarterial chemoembolization by using the Cancer of the Liver Italian Program system for prospective stratified randomization.

  1. Hepatocellular carcinoma complicating cystic fibrosis related liver disease.

    O'Donnell, D H

    2012-02-01

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

    Full Text Available Hepatocellular carcinoma (HCC is the most common malignant liver tumor, and there are limited systemic treatments for patients with advanced HCC. Regorafenib is an oral multi-kinase inhibitor, and phase III clinical trial has shown that regorafenib can significantly extend the median survival of patients with advanced HCC by 2.8 months, which makes it a second-line drug approved by FDA for the treatment of advanced HCC, just after sorafenib. This article reviews the basic and clinical research on regorafenib in the field of HCC.

    Full Text Available More and more clinical trials have proved the efficacy of targeted drugs in the treatment of hepatocellular carcinoma (HCC. With the development of science and technology, more and more targeted drugs have appeared. In recent years, targeted drugs such as regorafenib and ramucirumab have shown great potential in related clinical trials. In addition, there are ongoing clinical trials for second-line candidate drugs, such as c-Met inhibitors tivantinib and cabozantinib and a VEGFR-2 inhibitor ramucirumab. This article summarizes the advances in targeted drug therapy for HCC and related trial data, which provides a reference for further clinical trials and treatment.

  4. Prebiotics: A Novel Approach to Treat Hepatocellular Carcinoma.

    Fatima, Naz; Akhtar, Tasleem; Sheikh, Nadeem

    2017-01-01

    Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysaccharides triggers the activation of Toll-like receptors which stimulate the process of hepatocarcinogenesis. Prebiotics, nondigestible oligosaccharides, have a pivotal role to play when it comes to inducing an antitumor effect. A healthy gut flora balance is imperative to downregulation of inflammatory cytokines and reducing lipopolysaccharides induced endotoxemia, thus inducing the antitumor effect.

    2015-02-01

    Full Text Available Hedgehog (Hh signaling pathway is present in many animals and plays an important role in regulating embryonic development and differentiation. Aberrant activation of Hh signaling contributes to the pathogenesis of many malignancies. Recent studies have shown that dysregulated Hh signaling pathway participates in the tumorigenesis, tumor invasion, and metastasis of hepatocellular carcinoma (HCC. Investigation of the relationship between Hh signaling pathway and HCC will help elucidate the molecular mechanism of pathogenesis of HCC and provide a new insight into the development of novel anticancer therapy and therapeutic target.

    Although extrahepatic spread of hepatocellular carcinoma (HCC) is uncommon, it can be found anywhere in the body. Most extrahepatic metastases of HCC occur in patients with advanced-stage intrahepatic tumor, but incidental extrahepatic lesions have also occasionally been found in patients with early-stage intrahepatic HCC. The detection of extrahepatic metastatic disease is crucial when planning therapy for patients with HCC and should be used to avoid unnecessary surgical intervention. In this study we illustrate the radiologic findings of extrahepatic metastases of HCC involving various sites. The presumed mechanism of extrahepatic extension of HCC is also discussed. (orig.)

  7. Delayed hepatobiliary imaging in the diagnosis of hepatocellular carcinoma

    Chen, S.; Ma, Z.; Tang, Z.

    2000-01-01

    In recent years, the use of ultrasonography (US), X-CT and MRI has reduced the employment of isotopic explorations in the detection of hepatocellular carcinoma (HCC). But sometime the results of US, X-CT or MRI were different and diagnosis was very difficult. This present investigation was aimed to assess the usefulness of delayed hepatobiliary imaging in the diagnosis of HCC in these patients. Forty-eight patients consisting of 33 males and 15 females were entered into the research protocol. The mean age was 46 yr old (range 12-71 yr old). All of the patients were performed by surgery and verified histologically after nuclear examination. The subject was in a supine position under a gamma camera (Elscint, Apex Ap-6) and 555 MBq of Tc-99m-PMT were injected intravenously. The initial scinphotos obtained within 1 min after injection were used to image the blood pool phase. Subsequently, hepatic scans were obtained at 5 min, 1,2 and 5 hr. Anterior, right lateral and posterior hepatic images were recorded. According to the radioactive uptake by the lesion in delayed phase, the negative (no or minor uptake), positive (equal or greater uptake) or very strong positive (almost equal to the activity, of gallbladder) were judged. The positive were considered as diagnostic of HCC. And the very strong positive, were considered as diagnostic of benign hepatoma, such as adenoma or FNH. Thirty-seven of the forty-eight patients were HCC based on histology. Delayed imaging revealed increased or equilibrated uptake of radioactivity by the tumors in 22 of 37 patients with hepatocellular carcinoma. The sensitivity was 59.5%. One patient final diagnosis based on histology was focal nodular regenerative hyperplasia, and only the diagnosis with delayed hepatobiliary imaging before surgery was correct. Compared with US, X-CT and MRI, delayed hepatobiliary imaging had the highest specificity for diagnosis of hepatocellular carcinoma. In recent group, the specificity of Tc-99m-PMT delayed

    To explore the role of NQO1 overexpression for prognostic implication in hepatocellular carcinoma (HCC), NQO1 mRNA levels were detected in HCC fresh tissue samples of HCC and nontumor tissues, respectively. One hundred fifty-six cases of HCC meeting strict follow-up criteria were selected for immunohistochemical staining of NQO1 protein. Correlations between NQO1 overexpression and clinicopathological features of HCC were evaluated using χ 2 tests, survival rates were calculated using the Kaplan-Meier method, and the relationship between prognostic factors and patient 5-year survival was analyzed using Cox proportional hazards analysis. In results, the levels of NQO1 mRNA were significantly up-regulated in 14 fresh tissue samples of HCC. Immunohistochemical analysis showed that the NQO1 expression and overexpression rates were significantly higher in HCC samples compared with either adjacent nontumor tissues or normal liver tissues. NQO1 overexpression correlated to tumor size, venous infiltration and late pTNM stage of HCC. NQO1 overexpression was also related to low disease-free survival and 5-year survival rates. In the late-stage group, disease-free and 5-year survival rates of patients with NQO1 overexpression were significantly lower than those of patients without NQO1 expression. Further analysis using a Cox proportional hazards regression model revealed that NQO1 expression emerged as a significant independent hazard factor for the 5-year survival rate of patients with HCC. Therefore, NQO1 plays an important role in the progression of HCC. NQO1 may potentially be used as an independent biomarker for prognostic evaluation of HCC. Copyright © 2017.

  9. Living donor liver transplantation for hepatocellular carcinoma achieves better outcomes.

    Lin, Chih-Che; Chen, Chao-Long

    2016-10-01

    Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center. Although Taiwan Health Insurance Policy extended the Milan to University of California, San Francisco (UCSF) criteria in 2006, selection criteria will not be consolidated to take into account only by the morphologic size/number of tumors but also by their biology. The criteria are divided into modifiable image morphology, alpha fetoprotein (AFP), and positron emission tomography (PET) scan with standard uptake value (SUV) and unmodifiable unfavorable pathology such as HCC combined with cholangiocarcinoma (CC), sarcomatoid type, and poor differentiation. Downstaging therapy is necessary for HCC patients beyond criteria to fit all modifiable standards. The upper limit of downstaging treatment seems to be extended by more effective drug eluting transarterial chemoembolization in cases without absolute contraindications. In contrast, the pitfall of unmodifiable tumor pathology should be excluded by the findings of pretransplant core biopsy/resection if possible. More recently, achieving complete tumor necrosis in explanted liver could almost predict no recurrence after transplant. Necrotizing therapy is advised if possible before transplant even the tumor status within criteria to minimize the possibility of tumor recurrence. LDLT with low surgical mortality in experienced centers provides the opportunities of optimizing the pre-transplant tumor conditions and timing of transplant to achieve better

    BLZF1, a member of b-ZIP family, has been implicated in epigenetic regulation and Wnt/β-catenin signaling. Its expression and clinical significance in human cancers remain largely unknown. In this study, we showed that BLZF1 expression was reduced in hepatocellular carcinoma (HCC) tissues, compared to the paracarcinoma tissues, at both mRNA and protein levels. Results of immunohistochemistry revealed that BLZF1 was presented in both nuclear and cytoplasm. Decreased expression of nuclear and cytosolic BLZF1 in HCC was depicted in 68.2% and 79.2% of the 634 cases. Nuclear BLZF1 expression was significantly associated with tumor multiplicity (P = 0.048) and tumor capsule (P = 0.028), while cytosolic BLZF1 expression was correlated with serum AFP level (P = 0.017), tumor differentiation (P = 0.001) and tumor capsule (P = 0.003). Kaplan–Meier analysis indicated both nuclear and cytosolic BLZF1 expression was associated with poor overall survival. Low nuclear BLZF1 also indicated unfavorable disease-free survival and high tendency of tumor recurrence. Furthermore, multiple Cox regression analysis revealed nuclear BLZF1 as an independent factor for overall survival (Hazard Ratio (HR) = 0.827, 95% confident interval (95%CI): 0.697–0.980, P = 0.029). The prognostic value of BLZF1 was further confirmed by stratified analyses. Collectively, our data suggest BLZF1 is a novel unfavorable biomarker for prognosis of patients with HCC. - Highlights: • BLZF1 expression was much lower in HCC tissues. • Low BLZF1 expression was associated with poor outcomes in a cohort of 634 HCC patients. • Multiple Cox regression analysis indicated nuclear BLZF1 as an independent predictor for overall survival.

    Metastasis to the seminal vesicle is extremely rare for hepatocellular carcinoma (HCC). To our knowledge, it has been not reported in literature. The purpose of the present paper was to report a case of metastasis to the seminal vesicle after HCC resection, along with its histological features and immunohistochemical characteristics. A 46-year-old Chinese man was admitted to our hospital due to abdominal distension. He had a history of HCC related to hepatitis B virus infection. Moreover, left partial hepatectomy was performed in another hospital 28 months ago, and right partial hepatectomy for HCC recurrence in our hospital 4 months ago. After resection, radiofrequency ablation therapy had been performed. About 27 months after the initial operation, contrast-enhanced computed tomography (CT) of the pelvic cavity revealed a mass with homogeneous enhancement in the seminal vesicle. Transrectal needle biopsy revealed a poorly differentiated adenocarcinoma. Therefore, seminal vesiculectomy was resected. The histological diagnosis of the removed tumor was compatible with the original HCC. Immunohistochemical examination demonstrated that the tumor cells were positive for glypican-3 (GPC3), alpha-fetoprotein (AFP), hepatocyte paraffin-1 (Hep Par 1), cytokeratin 18 (CK 18), and hepatocyte antigen, which confirmed that the seminal vesicle tumor was a metastatic tumor of HCC. However, CT subsequently revealed multiple metastatic foci in the abdominal and pelvic cavities in May 2009 and August 2009, respectively. The seminal vesicle is an extremely rare metastatic site for HCC, and the prognosis is very poor. A combination of clinical and pathological features is necessary for a correct diagnosis, and primary tumor should be excluded before diagnosing metastatic foci

    2013-01-01

    Purpose: Evaluation of the sensitivity and specificity of glypican3 (GPC3) in differentiating hepatocellular carcinoma (HCC) from metastatic carcinomas of the liver in cell block material. Patients and methods: Sixty cell blocks were prepared from liver FNAs performed in the radiodiagnosis department, National Cancer Institute, in the period between August 2011 and May 2012. Cases diagnosed as hepatocellular carcinoma, or metastatic carcinoma were included in the study. Cell block sections were stained with anti GPC-3. Sensitivity, specificity, and positive and negative predictive values, of GPC3 were calculated. The final diagnosis was based on the triple approach of clinical data, radiological findings, as well as cytomorphologic features aided by GPC-3 results. Results: 70% of cases were diagnosed as HCC, and 30% as metastatic carcinomas. 95.2% of HCC cases expressed GPC3. Poorly differentiated cases showed the highest GPC3 sensitivity (100%), followed by moderately differentiated cases (96.5%), while well differentiated cases expressed GPC3 in 90% of cases. 83.3% of metastatic carcinomas were negative for GPC3. In this study, sensitivity of GPC-3 in HCC was 95.2%, specificity was 83.3%, positive and negative predictive values were 93% and 88.2% respectively, and total accuracy was 91.7%. Conclusion: Immunocytochemical staining for GPC3 in cell block material is a highly sensitive and specific method capable of distinguishing HCC from the vast majority of metastatic carcinomas of the liver

  13. Clinical significance of SNP (rs2596542 in histocompatibility complex class I-related gene A promoter region among hepatitis C virus related hepatocellular carcinoma cases

    2017-07-01

    Full Text Available The major histocompatibility complex class I-related gene A (MICA is an antigen induced by stress and performs an integral role in immune responses as an anti-infectious and antitumor agent. This work was designed to investigate whether (SNP rs2596542C/T in MICA promoter region is predictive of liver cirrhosis (LC and hepatocellular carcinoma (HCC or not. Forty-seven healthy controls and 94 HCV-infected patients, subdivided into 47 LC and 47 HCC subjects were enrolled in this study. SNP association was studied using real time PCR and soluble serum MICA concentration was measured using ELISA. Results showed that heterozygous genotype rs2596542CT was significantly (P = 0.022 distributed between HCC and LC related CHC patients. The sMICA was significantly higher (P = 0.0001 among HCC and LC. No significant association (P = 0.56 between rs2596542CT genotypes and sMICA levels was observed. Studying SNP rs2596542C/T association with HCC and LC susceptibility revealed that statistical significant differences (P = 0.013, P = 0.027 were only observed between SNP rs2596542C/T and each of HCC and LC, respectively, versus healthy controls, indicating that the rs2596542C/T genetic variation is not a significant contributor to HCC development in LC patients. Moreover, the T allele was considered a risk factor for HCC and LC vulnerability in HCV patients (OR = 1.93 and 2.1, respectively, while the C allele contributes to decreasing HCC risk. Therefore, SNP (rs2596542C/T in MICA promoter region and sMICA levels might be potential useful markers in the assessment of liver disease progression to LC and HCC.

  14. Primary hepatocellular carcinoma localised by a radiolabelled monoclonal antibody

    Markham, N; Ritson, A; James, O; Curtin, N; Bassendine, M; Sikora, K

    1986-01-01

    A rat monoclonal antibody, YPC2/38.8, was selected from a panel of antibodies derived by immunising rats with fresh human colorectal carcinoma. It was found to bind to a 30,000 dalton protein present on the cell surface of normal colon and liver. This protein was increased 10-fold on primary hepatocellular carcinoma (PHC) cells. After labelling with /sup 131/I, YPC2/38.8 was shown to localise human PHCs grown as xenografts in immunosuppressed mice. The authors conclude that YPC2/38.8 may have potential for diagnostic localisation and possibly thence for the selective targeting of drugs or toxins in patients with PHC arising in a liver unaffected by significant parenchymal disease. 16 refs.; 4 figs.; 1 table.

    Caturelli, Eugenio; Biasini, Elisabetta; Bartolucci, Francesca; Facciorusso, Domenico; Decembrino, Francesco; Attino, Vito; Bisceglia, Michele

    2002-01-01

    Purpose: To evaluate the utility of a second ultrasound-guided fine-needle biopsy of liver nodules thought to be hepatocellular carcinoma when the original biopsy has failed to provide a reliable diagnosis. Methods: Thirty-seven cirrhotic patients underwent ultrasound-guided fine-needle biopsy of liver nodules that were subsequently diagnosed as hepatocellular carcinoma. Each biopsy involved a single puncture with a 20 G cutting needle, which yielded pathologic material used both for cytologic and histologic studies. In 23 cases (mean diameter of nodules 48 mm) the biopsy furnished exclusively necrotic material (non-diagnostic subgroup); in the other 14 cases (mean diameter 26 mm) the biopsy yielded no neoplastic elements (false-negative subgroup). All 37 nodules were subjected to repeat biopsies performed in the same manner. Results: The repeat biopsies provided a diagnosis of hepatocellular carcinoma in six of the 23 patients from the non-diagnostic subgroup and in seven of the 14 in the false-negative subgroup. Overall, repeat biopsy produced a diagnostic gain of 35.1%. Conclusion: The chance of success with repeat biopsy of hepatocellular carcinoma is limited and may depend to some extent on the characteristics of the lesions (i.e., areas of necrosis in large nodules, well-differentiated cellular populations in small ones)

    2001-01-01

    The purpose of this study was to evaluate the CT findings of rupture of hepatocellular carcinoma (HCC) in the caudate lobe of the liver. The CT scans of five cases of rupture of HCC in the caudate lobe of the liver were retrospectively reviewed and correlated with clinical records. All cases showed exophytic tumors in the caudate lobe of the liver and high-attenuation hematomas in the lesser sac on CT. A lesser sac hematoma may be a sentinel clot sign of rupture of HCC in the caudate lobe. (orig.)

    Mazzola, G.; Virdone, R.; Orlando, A.; Turri, A.; Caltagirone, M.; Fusco, G.; Parisi, P.; Cottone, M.

    1989-01-01

    To study the sonographic (US) evolution of hepatocellular carcinoma, 53 tumors in 45 untreated patients were observed regulary with real-time US for a period of 6 to 56 months. At the beginning, 25 tumors were hypoechoic, 18 isoechoic, 4 hyperechoic, and 6 had mixed hypo/hyper echopatterns. At the follow-up, 7 initially hypoechoic tumors had changed to hyperechoic or to mixed echopatterns; 8 hypoechoic tumors had becom isoechoic; 9 of the 25 initially hypoechoic neoplastic lesions had maintained the same echodensity. Ten of the 15 initially isoechoic tumors had changed to mixed echopatterns and 5 had remained unchanged. Three initially isoechoic lesions and a hypoechoic one had turned into diffuse patterns; 2 initially hyperechoic neoplastic lesions had remained unchanged; 1 had switched into hypoechoic, and 1 changed to mixed echopattern; 4 out of 6 tumors with echopattern had remained unchanged, 1 had become hyperechoic and 1 hypoechoic. The current study has proven variou tumors ≤3 cm in diameter to be isoechoic and most tumors >3 in diameter to have mixed hypo/hyper echopatterns. The echogenicity of small hepatocellular carcinomas increases with the tumor growth and remains unchanged when they do not increase in size

    Hepatocellular carcinoma, one of the most common virus-associated cancers, is the third most frequent cause of cancer-related death worldwide. By massively parallel sequencing of a primary hepatitis C virus-positive hepatocellular carcinoma (36× coverage) and matched lymphocytes (>28× coverage) from the same individual, we identified more than 11,000 somatic substitutions of the tumor genome that showed predominance of T>C/A>G transition and a decrease of the T>C substitution on the transcribed strand, suggesting preferential DNA repair. Gene annotation enrichment analysis of 63 validated non-synonymous substitutions revealed enrichment of phosphoproteins. We further validated 22 chromosomal rearrangements, generating four fusion transcripts that had altered transcriptional regulation (BCORL1-ELF4) or promoter activity. Whole-exome sequencing at a higher sequence depth (>76× coverage) revealed a TSC1 nonsense substitution in a subpopulation of the tumor cells. This first high-resolution characterization of a virus-associated cancer genome identified previously uncharacterized mutation patterns, intra-chromosomal rearrangements and fusion genes, as well as genetic heterogeneity within the tumor.

  19. Proteomic Studies of Cholangiocarcinoma and Hepatocellular Carcinoma Cell Secretomes

    2010-01-01

    Full Text Available Cholangiocarcinoma (CCA and hepatocellular carcinoma (HCC occur with relatively high incidence in Thailand. The secretome, proteins secreted from cancer cells, are potentially useful as biomarkers of the diseases. Proteomic analysis was performed on the secreted proteins of cholangiocarcinoma (HuCCA-1 and hepatocellular carcinoma (HCC-S102, HepG2, SK-Hep-1, and Alexander cell lines. The secretomes of the five cancer cell lines were analyzed by SDS-PAGE combined with LC/MS/MS. Sixty-eight proteins were found to be expressed only in HuCCA-1. Examples include neutrophil gelatinase-associated lipocalin (lipocalin 2, laminin 5 beta 3, cathepsin D precursor, desmoplakin, annexin IV variant, and annexin A5. Immunoblotting was used to confirm the presence of lipocalin 2 in conditioned media and cell lysate of 5 cell lines. The results showed that lipocalin 2 was a secreted protein which is expressed only in the conditioned media of the cholangiocarcinoma cell line. Study of lipocalin 2 expression in different types of cancer and normal tissues from cholangiocarcinoma patients showed that lipocalin 2 was expressed only in the cancer tissues. We suggest that lipocalin 2 may be a potential biomarker for cholangiocarcinoma.

  20. Nanosecond pulsed electric field ablation of hepatocellular carcinoma.

    2011-01-01

    Hepatocellular carcinoma often evades effective therapy and recurrences are frequent. Recently, nanosecond pulsed electric field (nsPEF) ablation using pulse power technology has emerged as a local-regional, non-thermal, and non-drug therapy for skin cancers. In the studies reported here we use nsPEFs to ablate murine, rat and human HCCs in vitro and an ectopic murine Hepa 1-6 HCC in vivo. Using pulses with 60 or 300 ns and electric fields as high as 60 kV/cm, murine Hepa 1-6, rat N1S1 and human HepG2 HCC are readily eliminated with changes in caspase-3 activity. Interestingly caspase activities increase in the mouse and human model and decrease in the rat model as electric field strengths are increased. In vivo, while sham treated control mice survived an average of 15 days after injection and before humane euthanasia, Hepa 1-6 tumors were eliminated for longer than 50 days with 3 treatments using one hundred pulses with 100 ns at 55 kV/cm. Survival was 40% in mice treated with 30 ns pulses at 55 kV/cm. This study demonstrates that nsPEF ablation is not limited to effectively treating skin cancers and provides a rationale for treating orthotopic hepatocellular carcinoma in pre-clinical applications and ultimately in clinical trials.

    Concerns are raised about the representativeness of cell lines for tumours due to the culture environment and misidentification. Liver is a major metastatic destination of many cancers, which might further confuse the origin of hepatocellular carcinoma cell lines. Therefore, it is of crucial importance to understand how well they can represent hepatocellular carcinoma. The HCC-specific gene pairs with highly stable relative expression orderings in more than 99% of hepatocellular carcinoma but with reversed relative expression orderings in at least 99% of one of the six types of cancer, colorectal carcinoma, breast carcinoma, non-small-cell lung cancer, gastric carcinoma, pancreatic carcinoma and ovarian carcinoma, were identified. With the simple majority rule, the HCC-specific relative expression orderings from comparisons with colorectal carcinoma and breast carcinoma could exactly discriminate primary hepatocellular carcinoma samples from both primary colorectal carcinoma and breast carcinoma samples. Especially, they correctly classified more than 90% of liver metastatic samples from colorectal carcinoma and breast carcinoma to their original tumours. Finally, using these HCC-specific relative expression orderings from comparisons with six cancer types, we identified eight of 24 hepatocellular carcinoma cell lines in the Cancer Cell Line Encyclopedia (Huh-7, Huh-1, HepG2, Hep3B, JHH-5, JHH-7, C3A and Alexander cells) that are highly representative of hepatocellular carcinoma. Evaluated with a REOs-based prognostic signature for hepatocellular carcinoma, all these eight cell lines showed the same metastatic properties of the high-risk metastatic hepatocellular carcinoma tissues. Caution should be taken for using hepatocellular carcinoma cell lines. Our results should be helpful to select proper hepatocellular carcinoma cell lines for biological experiments. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Cholangiocarcinoma represents the second most common primary liver tumor after hepatocellular carcinoma. Mahanine, a carbazole alkaloid derived from Murraya koenigii (Linn.) Spreng, has been used as folk medicine in Thailand, where the liver fluke-associated cholangiocarcinoma is common. The expression of microphthalmia-associated transcription factor (MITF) is maintained at immunohistochemically undetectable levels in hepatocytes and cholangiocytes. To explore the regulation of MITF expression in the liver, we immunohistochemically analyzed the MITF expression using hepatocellular carcinoma and cholangiocarcinoma specimens of the human liver cancer tissue array. MITF immunoreactivity was detected in subsets of hepatocellular carcinoma (6 out of 38 specimens; 16%) and cholangiocarcinoma (2/7 specimens; 29%). Moreover, immunoreactivity for glioma-associated oncogene 1 (GLI1), a transcription factor of the Hedgehog signaling pathway, was detected in 55% of hepatocellular carcinoma (21/38 specimens) and 86% of cholangiocarcinoma (6/7 specimens). Importantly, MITF was detectable only in the GLI1-positive hepatocellular carcinoma and cholangiocarcinoma, and MITF immunoreactivity is associated with poor prognosis in patients with hepatocellular carcinoma. Subsequently, the effect of mahanine was analyzed in HepG2 human hepatocellular carcinoma and HuCCT1 and KKU-100 human cholangiocarcinoma cells. Mahanine (25 µM) showed the potent cytotoxicity in these hepatic cancer cell lines, which was associated with increased expression levels of MITF, as judged by Western blot analysis. MITF is over-expressed in subsets of hepatocellular carcinoma and cholangiocarcinoma, and detectable MITF immunoreactivity is associated with poor prognosis in patients with hepatocellular carcinoma. MITF expression levels may be determined in hepatic cancer cells by the balance between the Hedgehog signaling and the cellular stress.

    Objective: To determine the frequency of development of hepatocellular carcinoma in patients with chronic liver disease secondary to hepatitis C who had achieved sustained virological response with Interferon and Ribavirin therapy. Study Design: Retrospective descriptive study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from January 2007 to January 2012. Methodology: Hepatitis C related chronic liver disease patients who were treated with interferon and ribavirin, after they achieved sustained virological response, they were followed for a mean of 42 A+- 17 months. During this time, development of hepatocellular carcinoma was ascertained. All underwent surveillance with alpha-feto-protein and ultrasonography every 6 months. Results: Out of the 58 patients who had achieved sustained virological response, 3 developed hepatocellular carcinoma after a mean follow-up of 38 A+- 14 months. It was multifocal in 2 cases and was single lesion in the 3rd. Two patients ultimately died, one with upper GI bleeding and the other with hepatic encephalopathy, while 3rd patient with single lesion is still surviving. Conclusion: Three out of 58 patients of hepatitis C related chronic liver disease developed hepatocellular carcinoma during follow-up in patients who had achieved sustained virological response. These patients need closer follow-up, for development of complications, even if they have achieved sustained viral response. (author)

In previous studies, CMTM4 was reported to be downregulated and exhibited tumor-suppressor activities by regulating cell growth and cell cycle in clear cell renal cell carcinoma. However, its roles in tumorigenesis of hepatocellular carcinoma (HCC remain poorly studied. This study first investigated the expression of CMTM4 in HCC, and then examined the association between the expression of CMTM4 with the clinicopathological features and prognosis of HCC patients. It was found that CMTM4 was downregulated in HCC tissues, compared with matched adjacent nontumor tissues, as detected by immunohistochemistry. In addition, Kaplan–Meier survival analysis showed that the negative expression of CMTM4 was associated with decreased overall survival rates in patients with HCC. The results of this study suggest CMTM4 plays a role as a tumor suppressor in HCC and CMTM4 negative expression is a risk factor for poor prognosis of HCC.

    Pulmonary embolism complicated by transcatheter arterial chemoembolization (TACE) is known to be due to the use of large amount of lipiodol as an embolic agent. To our knowledge, massive tumoral pulmonary embolism following TACE and confirmed by surgery has not been described in the literature. In this report, we detail the case of a 49-year-old man in whom cyanosis and hypotension developed abruptly on the day of TACE. Chest CT revealed diffuse low-attenuated lesions in both pulmonary arteries. Histopathological specimens after emergent pulmonary arterial embolectomy confirmed the presence of massive tumor emboli of hepatocellular carcinoma

    The radiological surveillance of cirrhosis to detect the development of hepatocellular carcinoma (HCC) is problematic because no highly sensitive and specific imaging investigation is available. Ultrasound is typically the first modality used but is less accurate than other imaging modalities. We report the first case of a patient with cirrhosis in whom US imaging with liver-specific microbubbles detected an HCC prior to its detection by MR. The use of liver-specific microbubble US contrast agents is an exciting development in the detection of HCC in chronic liver disease and may help to rectify some of the shortcomings of US. (orig.)

    A simple outpatient follow-up system was developed with a laptop personal computer to assist management of patients with hepatocellular carcinoma after hepatic resections. Since it is based on a non-relational database program and the graphical user interface of Macintosh operating system, those who are not a specialist of the computer operation can use it. It is helpful to promptly recognize current status and problems of the patients, to diagnose recurrences of the disease and to prevent lost from follow-up cases. A portability of the computer also facilitates utilization of these data everywhere, such as in clinical conferences and laboratories.

    Full Text Available Liver cancer is the fifth most common cancer in men and the seventh in women. During the past 20 years, the incidence of HCC has tripled while the 5-year survival rate has remained below 12%. The presence of circulating tumor cells (CTC reflects the aggressiveness nature of a tumor. Many attempts have been made to develop assays that reliably detect and enumerate the CTC during the development of the HCC. In this case, the challenges are (1 there are few markers specific to the HCC (tumor cells versus nontumor cells and (2 they can be used to quantify the number of CTC in the bloodstream. Another technical challenge consists of finding few CTC mixed with million leukocytes and billion erythrocytes. CTC detection and identification can be used to estimate prognosis and may serve as an early marker to assess antitumor activity of treatment. CTC can also be used to predict progression-free survival and overall survival. CTC are an interesting source of biological information in order to understand dissemination, drug resistance, and treatment-induced cell death. Our aim is to review and analyze the different new methods existing to detect, enumerate, and characterize the CTC in the peripheral circulation of patients with HCC.

    Full Text Available Malignancy is characterized by anaplasia, invasiveness, and metastasis. Primary oral squamous cell carcinoma is the most prevalent oral malignancy, but secondary malignancy from distant sites have also been reported. Hepatocellular carcinoma (HCC is a common primary liver malignancy that frequently metastasizes during the course of the disease, but < 1% of cases show oral involvement. Such secondary neoplasms do not have any pathognomonic clinical or radiologic findings, and therefore they pose a diagnostic challenge. Hence, in the differential diagnosis of malignant tumors of the oral cavity, it is essential to consider the occurrence of both primary as well as metastatic tumors despite the low incidence of the latter. A rare case of HCC metastasizing to both the maxilla and mandible is presented, in which the patient succumbed to the disease as a result of the delay in diagnosis.

    2000-01-01

    Purpose of this work is to compare prospectively dynamic gadolinium (Gd)-enhanced with superparamagnetic iron oxide (SPIO)-enhanced MRI for the detection of hepatocellular carcinoma (HCC). Twenty-five patients with histologically proven HCC and liver cirrhosis (28% of them in B or C Child class) underwent dynamic Gd-enhanced MRI and, a few days later, (mean interval: three days) SPIO-enhanced MRI. Only patients with availability of clinical and imaging follow-up for at least seven months were enrolled in this prospective study. MR images were reviewed by two independent radiologists. The readers scored each lesion for the presence of HCC and assigned confidence levels based on a five-grade scale: 1, definitely or almost definitely absent; 2, possibly present; 3, probably present; 4, definitely present; 5, definitely present with optimal liver/lesion contrast or good liver/lesion contrast and morphological signs (intact capsule, intranodular septa, extracapsular infiltration), useful for locoregional treatment planning. A positive diagnostic value was assessed for scores of 3 or higher. Gd-enhanced and SPIO-enhanced MRI found 44 lesions. Eight of twelve lesions visible with a single contrast agent measured less than 1 cm in diameter. HCC detectability was 75% with Gd-enhanced MRI and 97.7% with SPIO-enhanced MRI. SPIO-enhanced T2-weighted TSE images showed significantly higher diagnostic value than SPIO-enhanced T1-T2*GRE images only in three cases, while nodule morphological characteristics (capsule, septa, different cell differentiation components) were better depicted by TSE images. In thi study the combined use of SPIO-enhanced T2-weighted TSE and T1-T2*-weighted GRE sequences showed higher sensitivity than gadolinium-enhanced GRE dynamic imaging (97.7% versus 75%). These results are at least partly related to our study conditions, that is: 1)MRI was performed with a 1T system, 2) both axial and sagittal SPIO-enhanced imaging were performed with respiratory

    To review all of epidemiological and etiological aspects of hepatocellular carcinoma (HCC) and examined the prevention of this disease in Asia. We conducted a systematic review according to the PRISMA guidelines. We were chosen articles that published previously, from PubMed (MEDLINE), the Cochrane database and Scopus. The key words used in this research were as follows: HCC in Asia and the way of prevention of this disease, with no language limitations. We selected those papers published before 2014 that we considered to be most important and appropriate. All relevant articles were accessed in full text and all relevant materials was evaluated and reviewed. More than 70% of all new cases of liver cancer were diagnosed in Asia, a region that 75% of all those chronically infected with hepatitis B virus (HBV) in the world. Chronic HBV infection is the main cause of HCC in Asia, where the virus is endemic and vertical transmission is common. Japan, Saudi Arabia, Egypt and Pakistan are exception because of high prevalence of HCV infection in these regions. The prevalence of this cancer is high in Eastern and South-Eastern Asia, But Middle Eastern countries are characterized as moderate prevalence rate of HCC region and Central Asia and some part of Middle Eastern countries are known as low prevalence rate of HCC. In addition of HBV and HCV the other factors such as aflatoxin, alcohol, obesity, diabetes and non-alcoholic fatty liver disease (NAFLD) might be responsible for a low prevalence of HCC in Asian countries. Currently available HCC therapies, chemotherapy, surgical are inefficient, mainly due to usually late diagnosis and high recurrence rates after surgical resection, and usually end with treatment failure. Liver transplantation also remains as a difficult strategy in patients with HCC. Thus prevention of HCC by treating and prevention HBV and HCV infection, the major causative agents of HCC, and the other risk factors such as aflatoxin, alcohol, obesity

    Alpha-fetoprotein is an effective biomarker as an aid in hepatocellular carcinoma detection in many countries. However, alpha-fetoprotein has its limitations, especially in early hepatocellular carcinoma diagnosis. Protein induced by vitamin K absence or antagonist-II is another biomarker that is used for hepatocellular carcinoma detection. The aim of this study is to compare the diagnostic performance of alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II alone and in combination to explore improving biomarker performance as an aid in early hepatocellular carcinoma detection. In this study a total of 582 serum samples including 132 hepatocellular carcinoma patients, 250 non-hepatocellular carcinoma patients, and 200 healthy volunteers were collected. Alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II levels were measured by both chemiluminescent enzyme immunoassay on LUMIPULSE platform and by chemiluminescent microparticle immunoassay on ARCHITECT platform. Receiver operation characteristic curve analyses were performed for each biomarker and in combination. The results showed that Alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II in combination have shown higher area under the curve compared to alpha-fetoprotein alone for diagnosis in whole patients (0.906 vs 0.870) in hepatocellular carcinoma early-stage patients (0.809 vs 0.77) and in hepatitis B virus-related hepatocellular carcinoma patients (0.851 vs 0.788) with ARCHITECT platform. Protein induced by vitamin K absence or antagonist-II showed higher area under the curve than alpha-fetoprotein for diagnosis of hepatitis B virus-related hepatocellular carcinoma patients (0.901 vs 0.788).We conclude that Combining alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II may improve the diagnostic value for early detection of hepatocellular carcinoma. Protein induced by vitamin K absence or antagonist-II performs better

  17. Current status of liver diseases in Korea: hepatocellular carcinoma.

    Song, Il Han; Kim, Kyung Sik

    2009-12-01

    Primary liver cancer, most of which is hepatocellular carcinoma (HCC), is the third common leading cancer in Korea. During the last two decades, the incidence rate of primary liver cancer has shown a modest decrease, but its mortality rate has slightly increased. The incidence of HCC, according to age, peaks in the late sixth decade in men and in the early seventh decade in women. Hepatitis B virus (HBV) is the most important risk factor, which represents approximately 70% of all HCC, and hepatitis C virus (HCV) and alcohol are the next in order of major risk factors for the development of HCC in Korea. HBV-associated HCC occurs 10 years earlier than HCV-associated HCC due to a more prolonged exposure to HBV, which is vertically transmitted almost from HBsAg-positive mother in HBV-endemic area. National Cancer Control Institute, which was reorganized in 2005, is now working for several national projects such as National Cancer Registration Program, National R&D Program for Cancer Control and National Cancer Screening Program. International collaboration for the clinico-epidemiologic research would be needed to provide the specific measures for managing HCC in diverse etiologic situations. Finally, the mechanisms of hepatitis virus-associated hepatocellular carcinogenesis might be clarified to provide insights into the advanced therapeutic and preventive approaches for HCC in Korea, where the majority of HCC originate from chronic HBV and HCV infections.

    Hepatocellular carcinoma is one of the most prevalent neoplasms and the leading cause of cancer-related mortality worldwide. Mitochondrial ribosomal protein S23 is encoded by a nuclear gene and participates in mitochondrial protein translation. Mitochondrial ribosomal protein S23 overexpression has been found in many types of cancer. In this study, we explored mitochondrial ribosomal protein S23 expression in primary hepatocellular carcinoma tissues compared with matched adjacent non-tumoral liver tissues using mitochondrial ribosomal protein S23 messenger RNA and protein levels collected from public databases and clinical samples. Immunohistochemistry was performed to analyze the relationship between mitochondrial ribosomal protein S23 and various clinicopathological features. The results indicated that mitochondrial ribosomal protein S23 was significantly overexpressed in hepatocellular carcinoma. High mitochondrial ribosomal protein S23 expression was correlated with the tumor size and tumor-metastasis-node stage. Moreover, patients with high mitochondrial ribosomal protein S23 expression levels presented poorer survival rates. Mitochondrial ribosomal protein S23 was an independent prognostic factor for survival, especially at the early stage of hepatocellular carcinoma. In addition, the downregulation of mitochondrial ribosomal protein S23 decreased the proliferation of hepatocellular carcinoma in vitro and in vivo. In conclusion, we verified for the first time that mitochondrial ribosomal protein S23 expression was upregulated in hepatocellular carcinoma. High mitochondrial ribosomal protein S23 levels can predict poor clinical outcomes in hepatocellular carcinoma, and this protein plays a key role in tumor proliferation. Therefore, mitochondrial ribosomal protein S23 may be a potential therapeutic target for hepatocellular carcinoma.

    Although hepadnaviruses are implicated in the etiology of hepatocellular carcinoma, the pathogenic mechanisms involved remain uncertain. Clonally propagated integrations of hepadnaviral DNA into cellular DNA can be demonstrated in most virally induced hepatocellular carcinomas. Integration occurs at random sites in cellular DNA, but the highly preferred sites in viral DNA are adjacent to the directly repeated sequence DR1, less often DR2, or in the cohesive overlap region.

    Irradiation exposure positive correlates with tumor formation, such as breast cancer and lung cancer. However, whether low dose irradiation induces hepatocarcinogenesis and the underlying mechanism remain poorly defined. In the present study, we reported that low dose irradiation facilitated the proliferation of hepatocyte through up-regulating HULC in vitro and in vivo. Low dose irradiation exposure elevated HULC expression level in hepatocyte. Deletion of heightened HULC erased the cells growth accelerated following low dose irradiation exposure. CDKN1, the neighbor gene of HULC, was down-regulated by overexpression of HULC following low dose irradiation exposure via complementary base pairing, resulting in promoting cell cycle process. Thus, our findings provide new insights into the mechanism of low dose irradiation-induced hepatocarcinogenesis through HULC/CDKN1 signaling, and shed light on the potential risk of low dose irradiation for the development of hepatocellular carcinoma in pre-clinical settings. © 2018 Wiley Periodicals, Inc.

    Full Text Available The purpose of the study was to examine the clinical and epidemiological data in patients with chronic hepatitis C (CHC and hepatocellular carcinoma (HCC before they sought specialized medical care. The study included 92 patients with CHC. All patients were divided into 2 groups: Group 1 consisted of CHC patients with HCC (n=45, and Group 2 (n=47 consisted of CHC patients without HCC. With the development of HCC in CHC patients, clinical manifestations were absent only in 2.2% of patients. Determining factors in HCC development are male sex, mature age, the maintained HCV replication, moderate and severe fibrosis, disease duration of more than 10 years, and the lack of effect of antiviral treatment.

    2017-09-20

    Hepatocellular carcinoma (HCC) is a primary liver malignancy, and is now the six most common in between malignancies. Early diagnosis of HCC with prompt treatment increases the opportunity of patients to survive. With the advances in understanding the molecular biology of HCC, new therapeutic strategies to treat HCC have emerged. There is a growing consensus that vitamins are important for the control of various cancers. Biochemical evidence clearly indicates that HCC cells are responsive to the inhibitory effect of vitamin D, vitamin D analogues and vitamin K. In this review, we summarize the mechanisms used by vitamin D and K to influence the development of HCC and the latest development of vitamin analogues for potential HCC therapy.

  5. Functional Roles and Therapeutic Applications of Exosomes in Hepatocellular Carcinoma

    Laura Santangelo

    2017-01-01

    Full Text Available Exosomes are important in intercellular communication. They assure the horizontal transfer of specific functional contents (i.e., proteins, lipids, RNA molecules, and circulating DNA from donor to recipient cells. Notably, tumor-derived exosomes (TDEs appear to be an important vehicle of specific signals in cancer, impacting on tumor growth and metastasis. Recent researches point to the characterization of exosomes in Hepatocellular Carcinoma (HCC, the major adult liver malignancy. In this review, we summarize current findings on HCC exosomes, focusing on the identification of noncoding RNAs as exosome-enriched functional regulators and new potential biomarkers. The great potential of exosomes in future HCC diagnostic and therapeutic approaches is underlined.

  6. Prebiotics: A Novel Approach to Treat Hepatocellular Carcinoma

    Naz Fatima

    2017-01-01

    Full Text Available Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysaccharides triggers the activation of Toll-like receptors which stimulate the process of hepatocarcinogenesis. Prebiotics, nondigestible oligosaccharides, have a pivotal role to play when it comes to inducing an antitumor effect. A healthy gut flora balance is imperative to downregulation of inflammatory cytokines and reducing lipopolysaccharides induced endotoxemia, thus inducing the antitumor effect.

  7. Herbal Medicine and Hepatocellular Carcinoma: Applications and Challenges

    2011-01-01

    Full Text Available Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC agent, enhancing our knowledge about their biologic functions and targets. However there is a significant distinction between the herbal medicine and the herbal production even though both are the plant-based remedies used in the practice. In this article, for the sake of clarity, the effective herbal compounds and herbal composite formulas against HCC are discussed, with emphasizing the basic conceptions of herbal medicine in order to have a better understanding of the prevention and treatment of HCC by herbal active compounds and herbal composite formulas.

    2015-01-01

    Full Text Available We would like to highlight the application of natural products to hepatocellular carcinoma (HCC. We will focus on the natural products known as flavonoids, which target this disease at different stages of hepatocarcinogenesis. In spite of the use of chemotherapy and radiotherapy in treating HCC, patients with HCC still face poor prognosis because of the nature of multidrug resistance and toxicity derived from chemotherapy and radiotherapy. Flavonoids can be found in many vegetables, fruits, and herbal medicines that exert their different anticancer effects via different intracellular signaling pathways and serve as antioxidants. In this review, we will discuss seven common flavonoids that exert different biological effects against HCC via different pathways.

    Full Text Available c-Met plays a pivotal role in the development and progression of hepatocellular carcinoma (HCC, which can lead to proliferation, survival, cytoskeleton reorganization, separation and diffusion, and angiogenesis of tumor cells. Moreover, c-Met is an important prognostic factor for HCC. In HCC, c-Met acts as an activator of a series of signaling pathways, including PI3K/AKT/mTOR, ERK/MAPK, and Rac-Pak. In recent years, it has been reported that small-molecule kinase inhibitors can abolish phosphorylation at the intracellular carboxyl terminal of c-Met, and then inhibit the recruitment of signal convertors and downstream signaling pathways, which finally achieve anti-tumor activities. Based on the carcinogenic activity of c-Met in HCC, this paper points out that selective inhibitors of c-Met hold promise for targeted therapies for HCC.

    2011-01-01

    Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. Radioembolization with yttrium-90 (Y90) microspheres is a new concept in radiation therapy for HCC. This review focuses on the indications, efficacy, side effects, and future direction of Y90 therapy, using TheraSphere® , in HCC patients. Comprehensive literature reviews have described the clinical and scientific evidence of Y90 therapy. The Radioembolization Brachytherapy Oncology Consortium has concluded that there is sufficient evidence to support the safe and effective use of this locoregional therapy in HCC patients, including those with portal vein thrombosis. There are currently no randomized clinical trials done on TheraSphere® and none of the studies so far have shown a survival benefit. Thus, although it represents a very promising therapy with excellent initial results, it cannot be fully recommended yet, till well-designed, large, randomized clinical studies are conducted showing survival benefits.

    A small percentage of patients with hepatocellular carcinoma (HCC) are candidates for curative treatment in form of resection or transplantation. There are different treatment options for unresectable HCC-like local ablative therapies and recently systemic therapy with Sorafenib. All of these have variable response rate and had been proven to improve survival. In the last few years, there is a growing interest in TheraSphere radioembolization. It consists of yttrium90 (Y-90) embedded into nonbiodegradable glass microspheres. It is selectively administered by intraarterial hepatic injection giving high doses of radiation to the tumor and sparing the liver parenchyma. It has been shown to improve survival and used as a bridge to transplantation and to downstage tumors for resection. Therasphere seems to have favorable safety profile and has been used in patients with portal vein thrombosis with successful outcome.

  12. CYCLOOXYGENASE-2 AND HEPATOCELLULAR CARCINOMA: THE PROTEOMICS OF ASSOCIATION

    2011-12-01

    Full Text Available Hepatocellular carcinoma represents one of the most common malignancies worldwide with a rising incidence in western countries. Chronic inflammation is recognised as a threat factor for cancer progression. Cyclooxygenase-2 is the major mediator of inflammation. Various studies on Cox-2 suggest its possible association with HCC differentiation. Sufficient genetic and pharmacologic evidences implicate its crucial role in neoplasia and it is also now clear that Cox-2 plays a crucial role in tumor progression. Cox-2 overexpression is associated with maintaining tumor microenvironment and has crucial implication for angiogenesis. Cox-2 operates in multifactorial fashion. Cox-2 selective inhibition has been reported as a successful tool in suppressing angiogenesis and metastasis. The pharmacological suppression of Cox-2 represents a bright future as a therapeutic tool for treatment of various malignancies. This review is an attempt to discuss the critical issue of overexpression of Cox-2 and its role in the development of HCC in particular and cancer in general.

  13. Research advances in cellular immunotherapy for primary hepatocellular carcinoma

    2014-09-01

    Full Text Available The present therapy for primary hepatocellular carcinoma (HCC consists of surgery as well as local radiotherapy and chemotherapy. However, the majority of patients are susceptible to recurrence after comprehensive treatment, and the overall treatment outcome is not ideal due to the lack of effective drugs and strategies. Increasing evidence has demonstrated that the immune system is closely related to the development, progression, metastasis, and recurrence of HCC. Thus, immune therapy, especially cellular immunotherapy, could regulate immune function and induce specific antitumor immunity to achieve the goal of controlling HCC and reducing its recurrence and metastasis, which has become an essential part in the comprehensive treatment of HCC. The findings in preclinical and clinical studies on cellular immunotherapy for HCC data are reviewed, and the current problems are discussed.

    1992-01-01

    We reported a phenomenon in which some hepatocellular carcinomas (HHCs) visualized as hypointense on plain T1 weighted MR images became hyperintense on gadolinium-DTPA (Gd-DTPA) (0.06∼0.23 mmol/kg) enhanced delayed images. Gd-DTPA enhanced images (using a super conducting magnet operating at 1.5T) of 44 HCCs were studied in comparison with contrast enhanced CT using 30∼80g of iodine. Six of 44 HCCs (14%) which were visualized as hypointense on plain T1 weighted image became hyperintense on delayed Gd-DTPA enhanced images. Although these were visualized as low intensity areas on both plain and enhanced CT, the contrast between HCC and the surrounding liver was small on post contrast CT. These findings were thought to be due to a stronger enhancement effect of Gd-DTPA than that of iodine. (author)

  15. Association between hepatitis B virus/hepatitis C virus infection and primary hepatocellular carcinoma risk: A meta-analysis based on Chinese population.

    2016-12-01

    To assess the relationship between hepatitis B virus (HBV), hepatitis C virus (HCV), and HBV/HCV double infection and hepatocellular carcinoma risk in Chinese population. The databases of PubMed and CNKI were electronic searched by reviewers according to the searching words of HBV, HCV, and hepatocellular carcinoma. The related case-control studies or cohort studies were included. The association between virus infection and hepatocellular carcinoma risk was demonstrated by odds ratio (OR) and 95% confidence interval (95% CI). The data were pooled by fixed or random effects model according to the statistical heterogeneity. The publication bias was assessed by Begg's funnel plot and Egger's linear regression test. Finally, 13 publications were included in this meta-analysis. For significant statistical heterogeneity (I2 = 99.8%,P = 0.00), the OR was pooled by random effects model. The pooled results showed that HBV infection can significantly increase the risk of developing hepatocellular carcinoma (OR = 58.01, 95% CI: 44.27-71.75); statistical heterogeneity analysis showed that significant heterogeneity existed in evaluation of HCV infection and hepatocellular carcinoma risk across the included 13 studies I2 = 77.78%, P = 0.00). The OR was pooled by random effects model. The pooled results showed that HCV infection can significantly increase the risk of developing hepatocellular carcinoma (OR = 2.34, 95% CI: 1.20-3.47); significant heterogeneity did not exist in evaluation HBV/HCV double infection and hepatocellular carcinoma risk for the included 13 studies (I2 = 0.00%,P = 0.80). The OR was pooled by fixed effects model. The pooled results showed that HBV/HCV double infection can significantly increase the risk of developing hepatocellular carcinoma (OR = 11.39, 95% CI: 4.58-18.20). No publication bias was found in the aspects of HBV, HCV, and HBV/HCV double infection and hepatocellular carcinoma. For Chinese population, HBV, HCV or HBV/HCV double infection can

    Diagnostic significance of computed tomography was studied in 45 cases with hepatocellular carcinoma. The diagnosis was correct in 95.6%, and in 66.6% of 21 cases with encapsulated hepatoma which shows expanding growth, its capsules were demonstrated by simple or contrast enhanced CT. Capsules surrounding tumor nodules were showed characteristic features; low density area by plain CT, and markedly enhanced high density or iso-density area around tumor nodules (called ''corona sign'') by contrast medium injection.

  17. Micronutrient Synergy in the Fight against Hepatocellular Carcinoma

    The incidence of hepatocellular carcinoma (HCC), once thought to be a rare tumor in North America, has rapidly increased in recent years in the United States. Current treatment modalities to halt the progression of this disease are only marginally effective. The mainstay treatment is liver transplantation, which is often confronted with donor shortage. Invasion, metastasis and recurrence contribute to the high mortality rate of this disease. Matrix metalloproteinases (MMPs) that degrade the extracellular matrix (ECM) have been associated with the progression, invasion and metastasis of the disease. We have developed strategies to strengthen the ECM collagen and inhibit MMPs through micronutrients such as lysine, proline and ascorbic acid. Addition of epigallocatechin gallate or green tea extract to these micronutrients synergistically enhanced anti-carcinogenic activity in HepG2 cells. Addition of certain other micronutrients, such as N-acetylcysteine, selenium, copper and zinc (NM) synergistically enhanced the anticancer activity of the mixture in a model of hepatocellular carcinoma using HepG2 cells. In vitro studies using HepG2 demonstrated that NM was very effective in inhibiting cell proliferation (by MTT assay), MMPs secretion (by gelatinase zymography), cell invasion (through Matrigel) and induction of apoptosis (by live green caspase). In addition, NM was shown to down-regulate urokinase plasminogen activator (by fibrin zymography) and up-regulate tissue inhibitors of metalloproteinases (by reverse zymography) in another HCC cell line, SK-Hep-1. MMP-2 and MMP-9 activities were further modulated by phorbol 12-myristate 13-acetate (PMA) induction and inhibited by NM. In previous studies, NM inhibited Sk-Hep-1 xenografts in nude mice and also inhibited hepatic metastasis of B16FO melanoma cells. Our results suggest that NM is an excellent candidate for therapeutic use in the treatment HCC by inhibiting critical parameters in cancer development and progression

  19. Hepatocellular carcinoma with bile duct involvement : computed Tomographic (CT) findings

    Lee, Joon Woo; Han, Joon Koo; Kim, Tae Kyoung; And others

    2000-01-01

    To describe the radiologic features of computed tomography (CT) in hepatocellular carcinoma (HCC) with bile duct involvement. We retrospectively analyzed the two phase spiral CT findings of 31 patients in whom HCC with bile duct invasion (n=3D28) or compression (n=3D3), was diagnosed. Eight of these underwent follow up CT after transarterial chemoembolization. We analyzed the size, type, location, enhancement pattern, and lipiodol retention of parenchymal and intraductal masses, as well as their lymphadenopathy. In all patients with bile duct invasion, single or multiple masses were demonstrated in the bile ducts. Intraductal masses showed the same enhancement characteristics as the parenchymal mass (kappa 0.550, p less than 0.001), and were contiguous to this mass. In 14 of 28 patients, intraductal masses filled the peripheral intrahepatic bile ducts and extended to the common bile ducts. In the other 14, the parenchymal mass extended to the area of the porta hepatis and then directly invaded the large ducts. In nine of the 28 patients, there was a hypoattenuated cleft between the intraductal mass and ductal wall. In six, a parenchymal mass was not apparent (n=3D2), or was smaller than 2cm (n=3D4). In five of eight patients (62.5%), follow-up CT after transarterial chemoembolization showed compact or partial lipiodol retention within the intraductal mass. In patients with bile duct compression, perihilar lymph nodes were noted along with the dilated intrahepatic duct but no intra ductal mass was demonstrated in the duct. Hepatocellular carcinomas cause bile duct dilatation either by direct invasion or by extrinsic compression of the bile duct with surrounding enlarged nodes. For the diagnosis of this condition, CT is helpful. (author)

  1. Non-transplant therapies for patients with hepatocellular carcinoma and Child-Pugh-Turcotte class B cirrhosis.

    Granito, Alessandro; Bolondi, Luigi

    2017-02-01

    Underlying liver cirrhosis is present in most patients with hepatocellular carcinoma, and liver transplantation is the only treatment strategy to cure both diseases. All other hepatocellular carcinoma treatment strategies have to take into account residual liver function that concurs with the patient's prognosis and might limit their feasibility. In patients with hepatocellular carcinoma and Child-Pugh-Turcotte class B (CPT-B), owing to borderline liver function, any intervention might be offset by liver function deterioration. In this setting, the decision for hepatocellular carcinoma treatment requires a comprehensive assessment of liver function, not restricted to the CPT classification, in addition to a careful evaluation of the prognostic effect of hepatocellular carcinoma compared with cirrhosis. In this Review, we provide an overview of the literature regarding the benefits and harms of non-transplant therapies in patients with hepatocellular carcinoma and CPT-B cirrhosis.

    Background: α-Fetoprotein (AFP) is a useful marker of hepatocellular carcinoma (HCC), and protein induced by vitamin K absence or antagonist II (PIVKA-II) and fucosylated AFP (AFP-L3) are specific tumor markers. Objective: The aim of this article was to report a case of intrahepatic cholangiocarcinoma (CC) with high levels of expression of AFP, AFP-L3, and PIVKA-II. Methods: A 70-year-old man weighing 66 kg with a diagnosis of intrahepatic CC presented with a liver tumor 4.0 cm in diameter and elevated concentrations of carbohydrate antigen 19-9 (575 U/mL), PIVKA-II (379 mAU/mL), and AFP (497 ng/mL; AFP-L3, 88.1%). On extended medial hepatic segmentectomy, microscopy showed that the tumor was a CC without HCC. The patient subsequently underwent immunohistochemical assessments using cytokeratin-19, epithelial membrane antigen (EMA), hepatocyte paraffin-1 (HP-1), PIVKA-II, and AFP. Results: In all specimens, desmoplasia was observed. However, results of immunohistochemistry showed positive results for cytokeratin-19 and EMA; HP-1 results were negative. Results of PIVKA-II and AFP testing in the tumor were positive. Conclusions: The case presented here showed characteristics of CC and HCC, whereas the histologic expression of the tumor suggested CC. Based on the literature search, this is the first known report of a case of a CC expressing AFP and PIVKA-II confirmed on immunohistochemical staining. This case is interesting with regard to the ability of the progenitor cells to differentiate HCC and CC. PMID:24678077

    Various techniques are available for radiotherapy of hepatocellular carcinoma, including three-dimensional conformal radiotherapy, linac-based intensity-modulated radiotherapy and helical tomotherapy. The purpose of this study was to determine the optimal radiotherapy technique for hepatocellular carcinoma. Between 2006 and 2007, 12 patients underwent helical tomotherapy for locally advanced hepatocellular carcinoma. Helical tomotherapy computerized radiotherapy planning was compared with the best computerized radiotherapy planning for three-dimensional conformal radiotherapy and linac-based intensity-modulated radiotherapy for the delivery of 60 Gy in 30 fractions. Tumor coverage was assessed by conformity index, radical dose homogeneity index and moderated dose homogeneity index. Computerized radiotherapy planning was also compared according to the tumor location. Tumor coverage was shown to be significantly superior with helical tomotherapy as assessed by conformity index and moderated dose homogeneity index (P=0.002 and 0.03, respectively). Helical tomotherapy showed significantly lower irradiated liver volume at 40, 50 and 60 Gy (V40, V50 and V60, P=0.04, 0.03 and 0.01, respectively). On the contrary, the dose-volume of three-dimensional conformal radiotherapy at V20 was significantly smaller than those of linac-based intensity-modulated radiotherapy and helical tomotherapy in the remaining liver (P=0.03). Linac-based intensity-modulated radiotherapy showed better sparing of the stomach compared with helical tomotherapy in the case of separated lesions in both lobes (12.3 vs. 24.6 Gy). Helical tomotherapy showed the high dose-volume exposure to the left kidney due to helical delivery in the right lobe lesion. Helical tomotherapy achieved the best tumor coverage of the remaining normal liver. However, helical tomotherapy showed much exposure to the remaining liver at the lower dose region and left kidney.

    1981-02-01

    sup(99m)Tc-phytate and /sup 67/Ga-citrate scintigraphies were evaluated clinically in 50 cases of histologically proven hepatocellular carcinoma. Detectability was higher in sup(99m)Tc-phytate scans than in /sup 67/Ga scans, and was influenced by the presence of liver cirrhosis. However, by using both scans, the highest detectability was obtained. /sup 67/Ga scan was useful especially in cases with equivocal sup(99m)Tc-phytate scintigraphy and cases with liver cirrhosis. There was no definite correlation seen between Edmondson's histological gradings and grades of /sup 67/Ga accumulation. No significant difference of /sup 67/Ga accumulation in hepatocellular carcinoma was observed regardless of the presence of liver cirrhosis. We conclude that it is better to use sup(99m)Tc-phytate as the first choice in screening of hepatocellular carcinoma and subsequent /sup 67/Ga scan if indicated.

    2005-01-01

    Objective: To investigate the relationship between enhancement in arterial-phase, indicating arterial blood supply of the lesions of hepatocellular carcinoma and lipiodol accumulation after the trans-arterial chemoembotherapy. Methods: CT images of primary hepatocellular carcinoma in 32 cases during the hepatic arterial-phase were retrospectively compared with the CT images of lipiodol distribution within the tumor after the trans-arterial chemoembotherapy. Results: The lipiodol distribution was classified into five types: homogeneous and compact(n=11), inhomogeneous though compact (n=7), scanty(n=5), poorly filled(n=3) and miscellaneous (n=3). The lipiodol has a homogeneous or inhomogeneous but compact distribution when remarkable enhancement of the tumor or dominant neoplastic vascularity was demonstrated during hepatic arterial-phase. The lipiodol distribution was scanty, poorly filled, or miscellaneous distributed in the nidus of the hepatocellular carcinoma with no or poor enhancement, or with hypo-vascularity during hepatic arterial-phase. Where there was abundant vascularity of the tumor, there would be a satisfying accumulation of the lipiodol. Conclusion: The CT assessmant of the arterial-phase vascularity of the hepatocellular provides valuable information of lipiodol accumulation after the trans-arterial chemoembotherapy. (authors)

  6. IS RESECTION OF HEPATOCELLULAR CARCINOMA IN THE ERA OF LIVER TRANSPLANTATION WORTHWILE? A single center experience

    Paulo HERMAN

    Full Text Available ABSTRACT Background - Liver resection for hepatocellular carcinoma is a potentially curative therapeutic procedure that can be performed readily after its indication, without the need of a long waiting time and lower costs when compared to liver transplantation, being a good alternative in patients with preserved/good liver function. Objective - Evaluate long-term results of liver resection from a high volume single center for selected patients with hepatocellular carcinoma in a context of a long waiting list for liver transplant. Methods - One hundred and one patients with hepatocellular carcinoma, with a mean age of 63.1 years, and preserved liver function were submitted to liver resection. Clinical and pathological data were evaluated as prognostic factors. Mean follow-up was 39.3 months. Results - All patients had a single nodule and 57 (58.2% patients were within the Milan criteria. The size of the nodule ranged from 1 to 24 cm in diameter. In 74 patients, liver resection was performed with the open approach and in 27 (26.7% was done laparoscopically. Postoperative morbidity was 55.3% being 75.5% of the complications classified as Dindo-Clavien I and II and operative mortality was 6.9%. Five-year overall and disease free survival rates were 49.9% and 40.7%, respectively.After a log-rank univariate analysis, the levels of preoperative alpha-fetoprotein (P=0.043, CA19-9 (P=0.028, capsule invasion (P=0.03, positive margin (R1-R2 (P=0.004 and Dindo-Claviens' morbidity classification IV (P=0.001 were the only parameters that had a significant negative impact on overall survival. On the odds-ratio evaluation, the only significant factors for survival were high levels of alpha-fetoprotein (P=0.037, and absence of free margins (P=0.008. Conclusion - Resection, for selected cases, is a potentially curative treatment with acceptable morbidity and mortality and, in a context of a long waiting list for transplant, plays an important role for the

  7. Knockdown of long noncoding RNA linc-ITGB1 suppresses migration, invasion of hepatocellular carcinoma via regulating ZEB1.

    2017-11-01

    This research focuses on the influence of linc-ITGB1 on the metastasis of hepatocellular carcinoma and further explores its underlying mechanism. A total of 70 hepatocellular carcinoma patients were chosen for our study. RT-qPCR was used for detecting the expression level of linc-ITGB1 in their cancer tissues. Moreover, the expression level of linc-ITGB1 was also detected in hepatocellular carcinoma cell lines. Furthermore, whether linc-ITGB1 could affect the migrated and invaded ability of hepatocellular carcinoma cells was determined by wound healing assay and transwell assay. We further explored the potential mechanism by RT-qPCR and Western blot assay. Linc-ITGB1 expression level in hepatocellular carcinoma tissues was remarkably higher than that in adjacent tissues. Moreover, migrated and invaded ability of hepatocellular carcinoma cells was inhibited through knockdown of linc-ITGB1. Further study revealed that silenced linc-ITGB1 inhibited the expression of ZEB1 and then suppressed epithelial to mesenchymal transition (EMT), which was important during the metastasis of hepatocellular carcinoma. Moreover, the inhibition of cell invasion by silenced linc-ITGB1 could be rescued through overexpression of ZEB1 in hepatocellular carcinoma. The results indicate that linc-ITGB1, a novel oncogene in tumorigenesis, could promote the metastasis and EMT via ZEB1, which may offer a possible therapeutic target in hepatocellular carcinoma.

    1992-01-01

    To evaluate the effectiveness of superselective transcatheter arterial embolization (STAE) for hepatocellular carcinoma (HCC) with a mixture of ethanol and Lipiodol, STAE was done in 12 male patients with HCC. There were diagnosed clinically with angiographic findings and elevated alphafetprotein levels and three were recurrent tumors after surgery. Sono-guided aspiration biopsy proved the diagnosis of hepatocellular carcinoma in another six patients. The tumor was a small single nodule (2-5cm in diameter) in 11 patients. In one patient, two nodules were found. Superselective catheterization was done using 3F Tracker catheter (Target Therapeutics USA) coaxially through 6F catheter into the feeding hepatic artery, usually the third order branch. One to four cc of 75% ethanol mixed with Lipiodol was infused under fluoroscopy immediately after injection of 2% lidocaine. Immediate angiography and CT after 2 weeks were undertaken. Complete segmental or subsegmental devascularization including feeding arteries and tumor vascularities occurred in all patients. Follow-up angiography after 6 to 15 months revealed the tumor opacified by Lipiodol. The tumor decreased in 5 cases and recurrence was found in three patients. CT taken 2 weeks after STAE showed low density halo around the tumor in 5 cases. Subsequent segmentectomy in four patients revealed total or near total necrosis of the tumor and no evidence of damage in surrounding parenchyma. STAE for HCC with a mixture of ethanol and Lipiodol is an effective and safe measure for small HCC

  9. Clinical significance of Tc-99m colloid liver angiography for the diagnosis of hepatocellular carcinoma

    Odano, I; Sakai, K; Sueyama, H [Niigata Univ. (Japan). School of Medicine

    1982-03-01

    Tc-99m phytate liver angiography was accomplished in 191 cases with focal liver disease at the same time of performing conventional liver scintigraphy from July 1978 to Feb. 1981. This simple method was considered to be useful to appreciate tumor vascularity in the liver, which was shown as dynamic radioactivity in the defect of the liver scintigram. Hypervascular pattern was defined as a high-radioactivity on the arterial phase of RI angiography, which corresponded to the filling defect on the static liver scintigram. This pattern was influenced by three factors, i.e. pathological vascularization of the tumor, size of the filling defect and position of the defect in the liver. In 29 cases (74%) of 39 hepatocellular carcinoma, hypervascular pattern was observed. When mean diameter of defect was more than 5.5 cm on liver scintigram, it was supposed that hypervascular pattern should be observed in probability of 84%. The smallest mean diameter of defect in which this pattern was seen was 3.0 cm. When a filling defect was situated at the posterior region of the right lobe of the liver, it was sometimes difficult to appreciate the vascular pattern. Tc-99m phytate liver angiography was considered to be a useful method for screening hepatocellular carcinoma.

    Objective: To study the significance of E-cadherin (E-cad) expression of primary hepatocellular carcinoma (PHC), and the effect of the different chemo-embolization treatment on E-cad. Methods:Ninety-eight histopathological verified PHC specimens were obtained. The patients were treated with surgical resection alone (57 cases), and second stage surgical resection after four kinds of chemo-embolization (41 cases). Strept avidin-biotin complex (SABC) immunohistochemical staining with monoclonal antibody against human E-cad was used to observe the E-cad in all specimens. The experimental results were compared with the surgical and clinical findings. Results: The metastatic rates in E-cad (+) and (-) were 43.3%, 70.4% respectively (x 2 = 4.22, P 0.05). The E-cad expression of trabecular and clear cell PHC was higher than that of solid and poorly differentiated PHC. After chemo-embolization, the E-cad expression of the former decreased, the latter increased. The E-cad expression decreased as pathologic grades increasing. After chemo-embolization, the E-cad expression increased as pathological grades increasing. The metastatic rates in interventional group and surgical resection alone were 48.8%, 56.1% respectively (P > 0.05). Conclusions: The increased expression of E-cad would restrain PHC from metastasis. It could act as a prognosis-predictive marker. The effect of chemo-embolization on E-cadherin expression of primary hepatocellular carcinoma had histopathologic difference

    2012-09-01

    Full Text Available Transcatheter arterial chemoembolization (TACE has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

  12. Can non-selective beta-blockers prevent hepatocellular carcinoma in patients with cirrhosis?

    Thiele, Maja; Wiest, Reiner; Gluud, Lise Lotte

    2013-01-01

    Hepatocellular carcinoma is the main liver-related cause of death in patients with compensated cirrhosis. The early phases are asymptomatic and the prognosis is poor, which makes prevention essential. We propose that non-selective beta-blockers decrease the incidence and growth of hepatocellular...... and growth of hepatocellular carcinoma. Rodent and in vitro studies support the hypothesis, but clinical verification is needed. Different study designs may be considered. The feasibility of a randomized controlled trial is limited due to the necessary large number of patients and long follow......-up. Observational studies carry a high risk of bias. The meta-analytic approach may be used if the incidence and mortality of hepatocellular carcinoma can be extracted from trials on variceal bleeding and if the combined sample size and follow up is sufficient....

    Full Text Available Advanced hepatocellular carcinoma carries a bad prognosis with a survival of only few months. Barcelona Clinic Liver Cancer (BCLC Guidelines recommended sorafenib monotherapy as the treatment modality for advanced BCLC Stage C disease, citing a two-month increase in survival rates. Here, we highlight a case with advanced HCC (BCLC Stage C treated with combination therapy of liver resection and Sorafenib therapy. The patient’s current survival rate was beyond 10 months. We also discuss the current evidence on liver resection with Sorafenib therapy in hepatocellular carcinoma. The description of the case may benefit in future diagnosis and treatment.

    Sorafenib is an oral multikinase inhibitor that has been proven effective as a single-agent therapy in hepatocellular carcinoma, and there is a strong rationale for investigating its use in combination with other agents. Vitamin K2 is nearly non-toxic to humans and has been shown to inhibit the growth of hepatocellular carcinoma. In this study, we evaluated the effects of a combination of sorafenib and vitamin K2 on the growth of hepatocellular carcinoma cells. Flow cytometry, 3-(4,5-dimethyl-2-thiazolyl-2,5-diphenyl-2H-tetrazolium bromide) and nude mouse xenograft assays were used to examine the effects of sorafenib and vitamin K2 on the growth of hepatocellular carcinoma cells. Western blotting was used to elucidate the possible mechanisms underlying these effects. Assays for 3-(4,5-dimethyl-2-thiazolyl-2,5-diphenyl-2H-tetrazolium bromide) revealed a strong synergistic growth-inhibitory effect between sorafenib and vitamin K2. Flow cytometry showed an increase in cell cycle arrest and apoptosis after treatment with a combination of these two drugs at low concentrations. Sorafenib-mediated inhibition of extracellular signal-regulated kinase phosphorylation was promoted by vitamin K2, and downregulation of Mcl-1, which is required for sorafenib-induced apoptosis, was observed after combined treatment. Vitamin K2 also attenuated the downregulation of p21 expression induced by sorafenib, which may represent the mechanism by which vitamin K2 promotes the inhibitory effects of sorafenib on cell proliferation. Moreover, the combination of sorafenib and vitamin K2 significantly inhibited the growth of hepatocellular carcinoma xenografts in nude mice. Our results determined that combined treatment with sorafenib and vitamin K2 can work synergistically to inhibit the growth of hepatocellular carcinoma cells. This finding raises the possibility that this combined treatment strategy might be promising as a new therapy against hepatocellular carcinoma, especially for patients

    Lim, J.H.; Kim, S.H.; Lee, W.J.; Choi, D.; Kim, S.H.; Lim, H.K.

    2006-01-01

    AIM: The aim of this study was to determine the sensitivity of ultrasonography for detecting hepatocellular carcinoma in patients who underwent surgical liver resection. MATERIALS AND METHODS: The preoperative ultrasonography reports of 103 patients who underwent hepatic resection surgery were retrospectively reviewed. The patients had chronic liver disease with good liver function and a relatively normal liver echotexture. The presence of a mass or masses in the resected part of the liver segments on preoperative ultrasonography was regarded as possible hepatocellular carcinoma, and these results were compared with the surgically resected hepatic lobes or segments. Accuracy for detection was assessed on a lesion-by-lesion basis, on a segment-by-segment basis, and on a patient basis. RESULTS: One hundred and fifty-seven hepatocellular carcinomas were found in 244 hepatic segments of 103 patients. One hundred and one of 157 hepatocellular carcinomas were detected using ultrasonography in 97 patients resulting in a sensitivity of 64%. In six patients, a solitary hepatocellular carcinoma was missed in each patient, a patient sensitivity being 94%. Using ultrasonography, 87 of 100 (87%) hepatocellular carcinomas larger than 2 cm in diameter, and 14 of 57 (25%) hepatocellular carcinomas 2 cm or smaller in diameter were revealed. On the basis of segment-by-segment analysis, the sensitivity was 78% (99 of 127 segments), specificity was 97% (114 of 117 segments), accuracy was 87% (213 of 244 segments), positive predictive value was 97% (99 of 102 segments), and negative predictive value was 80% (114 of 142 segments). CONCLUSION: In patients with chronic liver disease and good hepatic function, ultrasonography has a sensitivity of 94% in the identification of affected patients, but for individual lesions, the sensitivity is only 64%

    This study examined and compared the incidence patterns of hepatocellular carcinoma among age groups in Taiwan, 30 years after a universal hepatitis B virus immunization program was launched. Data for hepatocellular carcinoma diagnosed in 2003-2011 were collected from the population-based Taiwan Cancer Registry. Age-standardized incidence rates were calculated to analyze and compare the changes in incidence rates and trends. More specific analyses were performed on four age groups separated by sex. A total of 82,856 patients were diagnosed with hepatocellular carcinoma in 2003-2011 in Taiwan, yielding an age-standardized incidence rate of 32.97 per 100,000 person-years. Hepatocellular carcinoma was predominantly diagnosed in middle-aged adults (50.1%) and elderly people (49.1%), in contrast to the low incidences in children (0.04%) and adolescents and young adults (0.8%). Striking variations in trends were found for children (annual percent change: -16.6%, 2003-2010) and adolescents and young adults (annual percent change: -7.9%, 2003-2011). The incidence rate of hepatocellular carcinoma in children decreased to zero in 2011; only a slight decline in trends occurred for the middle-aged group (annual percent change: -2%, 2003-2011), and a slight upward trend was observed for elderly people (1.3%), specifically in women (1.7%). In Taiwan, hepatitis B virus-related hepatocellular carcinoma was nearly eradicated in children in 2011. The findings on age-specific incidence patterns and trends of hepatocellular carcinoma suggest that different control strategies for treating this devastating disease in the future be made according to age.

    Mori, H; Futagawa, S; Hayashi, K; Amagasaki, Y; Ochi, M [Nagasaki Univ. (Japan). School of Medicine

    1982-04-01

    Nine cases of hepatocellular carcinoma which have invaded the intra- and extrahepatic portal vein were evaluated by computed tomography (CT) and ultrasonography (US). The outstanding CT and sonographic features of the portal vein tumor thrombus were described. In CT, contrast opacification of normal portal vein and its major tributaries were not observed, and they were replaced by a soft tissue density mass representing the tumor thrombus. The thrombus measured 35 - 45 Hounsfield units (HU) in precontrast scans and 60 - 80 HU in postcontrast scans. The portal vein tumor thrombus showed a branched pattern of low density in porta hepatis and intrahepatic region due to differences in attenuation coefficients of the thrombus and adjacent noncancerous hepatic parenchyma on postcontrast scans. In ultrasound study, tumor thrombus was recognized as an echogenic solid mass in the porta hepatis obliterating the normal portal venous structures, or as an intraluminal solid mass in the dilated portal vein and its branches. Numerous collateral venous channels surrounding the thrombosed portal vein were also demonstrated on both CT and US. Particular emphasis was placed on the clinical implications of these non-invasive detection of the portal vein tumor thrombosis in patients with hepatocellular carcinoma.

    2002-01-01

    Objective: To study the helical CT signs of the hepatocellular carcinoma (HCC) after percutaneous microwave coagulation therapy (PMCT) and to evaluate the correlation between the helical CT signs and the therapeutic effect of HCC. Methods: The helical CT signs were analyzed in 22 cases with 26 lesions of the hepatocellular carcinoma that were treated with PMCT under ultrasonic guidance. Results: In 21 lesions, no enhancement was detected in the lesion border or inside the lesion at hepatic arterial phase (HAP) and portal venous phase (PVP). In 7 lesions, the slight or marked patchy enhancement was revealed in the surrounding liver of the lesions in HAP. In 5 lesions, nodular enhancement was found in the lesion border or inside the lesion in HAP. Conclusion: The dual-phase helical CT might be accurate in judging the therapeutic effect of HCC after PMCT. If no enhancement was showed in the lesions in the dual-phase helical CT, it indicated that no tumor survived. If slight or marked patchy pattern enhancement was revealed in the surrounding liver of the lesions in HAP, it was a normal reaction after PMCT. If nodular enhancement was found in the lesion border or inside the lesion in HAP, it indicated that the tumor partially survived

    2000-01-01

    Prognostic factors in the treatment of local advanced hepatocellular carcinoma with radiotherapy, transcatheter arterial embolization and arterial infusion. The treatment effects of radiotherapy and combination modality therapy for the local advanced hepatocellular carcinoma (HCC) were retrospectively reviewed. Three hundred and fifty-six patients of HCC (187 recurrent cases after surgical resection) were treated by: radiotherapy only ; bi-therapeutic method: hepatic artery ligation (HAL) and/or hepatic artery embolization (HAE) plus radiotherapy; and tri-therapeutic method (bi-therapeutic method plus hepatic artery infusion) from 1975 to 1996. Kaplan-Meier method has been used to evaluate the survival rates. There were no significant differences among these three treatment groups in the symptom relied rate, but the mean relief time period was much shorter in radiotherapy alone group (2.5 vs 44 months, P 0.05). There were evident differences in five-year survivals among these three treatment groups: 0 % for radiotherapy alone, 22.8 % for bi-therapeutic method and 38.8 % for tri-therapeutic method (P < 0.01). The prognosis was influenced by Okuda classification. Non-resectable local advanced HCC can be treated by the combination modality therapy, including radiotherapy, with a quite high cure rate. Radiotherapy alone can relief the symptoms. (authors)

  20. Contemporary management of fibrolamellar hepatocellular carcinoma: diagnosis, treatment, outcome, prognostic factors, and recent developments.

    Kassahun, Woubet Tefera

    2016-05-23

    Fibrolamellar hepatocellular carcinoma (FL-HCC) is a malignant liver tumor which is thought to be a variant of conventional hepatocellular carcinoma (HCC). It accounts for a small proportion of HCC cases and occurs in a distinctly different group of patients which are young and usually not in the setting of chronic liver disease. The diagnosis of FL-HCC requires the integration of clinical information, imaging studies, and histology. In terms of the treatment options, the only potentially curative treatment option for patients who have resectable disease is surgery either liver resection (LR) or liver transplantation (LT). When performed in a context of aggressive therapy, long-term outcomes after surgery, particularly liver resection for FL-HCC, were favorable. The clinical outcome of patients with unresectable disease is suboptimal with median survival of less than 12 months. The aim of this review is to update the available evidence on diagnosis, treatment options, outcome predictors, and recent developments of patients with this rare disease and to provide a summarized overview of the available literature.

  1. Hepatitis E virus infection as a promoting factor for hepatocellular carcinoma in Cameroon: Preliminary Observations

    2017-11-01

    Full Text Available Objectives: To determine the seroprevalence of hepatitis E virus (HEV infection in patients with chronic hepatitis and/or hepatocellular carcinoma (HCC and to assess its potential consequences for disease progression. Methods: We conducted a prospective case-control study on patients with HCC hepatitis B or C related and non-HCC patients including patients with CLD and patients without clinical evidence of liver disease. Anti-HEV IgG and IgM were tested by ELISA using commercially available kits. Liver damage was assessed by alanine aminotransferase, aspartate aminotransferase, platelets and prothrombin measurements. Results: We observed a significant anti-HEV IgG carriage in HCC patients compared to non-HCC subjects with CLD (41.8% vs 12.6%; P = 9.1 E-6; OR = 4.8, 95%CI: 2.3-10.6. HCC patients with HEV infection display more profound alterations of circulating liver enzymes, platelets count and prothrombin time than HCC patients without sero-reactivity to HEV. Conclusion: Overall, this study indicates a high prevalence of HEV infection in Cameroonian patients with CLD and HCC. These data suggest either that patients with liver tumors are more susceptible to hepeviral infection or that, in a tropical context, HEV might promote the progression of liver diseases towards tumor.

    2009-01-01

    Objective: To study the value of MSCT in evaluating the recent curative effect of hepatocellular carcinoma (HCC) after the chemotherapy with Oxaliplatin combined with 5-FU and Folinic Acid. Methods: 6 cases with HCC or post hepatectomy metastasis HCC confirmed by pathohistology underwent chemotherapy with Oxaliplatin combined with 5-FU and Folinic Acid. MultiSpiral Computed Tomography was used to determine the target lesions before and after the chemotherapy. The size of the target lesions before the chemotherapy was refer as the basic value (x0), and that after the chemotherapy was regarded as the observed value (y1). The theoretic value was obtained based on tumor growth dynamics mathematic model y2(x)=X 0 2 t/3td . Results: Before and after the first chemotherapy or between the consecutive chemotherapy cycles, the target lesions could be follow-up one by one with MSCT. There was significant statistical difference between observed increase size and theoretical increase size, P=0.0442. Conclusion: Tumor growth velocity can be effectively controlled with this chemotherapy plan, and MSCT may used to be an objective tool to evaluate the recent curative effect of chemotherapy on hepatocellular carcinoma.

  3. Glycogen metabolism in radiation induced hepatocellular carcinoma in Swiss albino mice

    Gupta, N.K.; Kumar, Ashok

    1988-01-01

    Glycogen content and the activities of phosphorylase, glycogen sythetase (GS), glucose 6-phosphatase (G6Pase), phosphohexose isomerase (PHI), glucose 6-phosphodehydrogenase were biochemically determined in the heparocellular carcinoma induced in swiss albino mice following radiocalcium internal irradiation. The content glycogen and the activities of phosphorylase, glycogen synthetase, G6Pase, PHI, GPT and GOT are considerably reduced in the hepatocellular carcinoma compared to that in control liver. However, the activity of G6PDH shows an increased activity. Results indicate that the decreas ed glycogen content in the hepatocellular carcinoma is due to the reduced glycogen synthetase activity and utilization of glucose by HMP pathway.

    Objective: To evaluate the value of multislice spiral CT (MSCT) in transcatheter arterial chemoembolization of the hepatocellular carcinoma. Methods: MSCT were performed in 54 cases of HCC before interventional procedure. CT findings of hepatic artery phase, portal venous phase and hepatic venous phase were observed respectively. CTA were done in 12 cases, the anatomy of celiac artery and its branches were observed. The schemes of interventional therapy were worked out according to the findings of MSCT. The demonstration of lesions and its complications were compared between CT and DSA. Reconstruction of celiac artery branches used the technique of VRT, MIP or MPR. Results: MSCT showed 225 lesions, 10 cases tumor thrombosis of portal vein, 1 case hepatic arteriovenous shunt, and 13 cases hepatic arterioportal shunt. Positive rate of MSCT in showing number of tumor lesions, tumor thrombosis in portal vein was slightly higher than that of DSA, but there was no significant difference (P>0.05). Showing of 3D reconstruction of celiac artery branches in CTA is better than that in DSA, Showing of angles between celiac artery and abdominal aorta in MSCT is more convenient than that in DSA. MSCT showed 5 cases hepatic artery original abnormality. The results were in accord with that in DSA. Five cases were demonstrated of multiple supply blood vessels of tumor in MSCT, It was slightly lower than that of DSA. Conclusion: MSCT is of importance for guidance of transcatheter arterial chemoembolization of the hepatocellular carcinoma, delay time of CT scan is the key to the showing of lesions and blood vessels.

    2014-10-01

    Full Text Available Background: Transarterial chemoembolization is the preferred treatment for unresectable, intermediate-stage hepatocellular carcinoma. Survival after transarterial chemoembolization can be highly variable. The purpose of this study is to identify the factors that predict overall survival of patients with unresectable hepatocellular carcinoma who undergo transarterial chemoembolization as the initial therapy. Methods:We included patients who underwent transarterial chemoembolization from 2007 to 2012 in this study. Patient’s age, gender, cause of cirrhosis, Child-Turcotte-Pugh score, model of end-stage liver disease score, Cancer of the Liver Italian Program score, Okuda stage, alpha- fetoprotein level, site, size and number of tumors were recorded. Radiological response to transarterial chemoembolization was assessed by computerized tomography scan at 1 and 3 months after the procedure. Repeat sessions of transarterial chemoembolization were performed according to the response. We performed survival assessment and all patients were assessed for survival at the last follow-up. Results: Included in this study were 71 patients of whom there were 57 (80.3 % males, with a mean age of 51.9±12.1 years (range: 18-76 years. The mean follow-up period was 12.5±10.7 months. A total of 31 (43.7% patients had only one session of transarterial chemoembolization, 17 (23.9% underwent 2 and 11 (15.5% had 3 or more sessions. On univariate analysis, significant factors that predicted survival included serum bilirubin (P=0.02, esophageal varices (P=0.002, Cancer of the Liver Italian Program score (P=0.003, tumor size (P=0.005, >3 sessions of transarterial chemoembolization (P=0.006 and patient's age (P=0.001. Cox regression analysis showed that tumor size of 1 transarterial chemoembolization session (P=0.004 were associated with better survival. Conclusion: Our study demonstrates that survival after transarterial chemoem- bolization is predicted by tumor size

    AIM: To evaluate the efficacy of ursodeoxycholic acid (UDCA) as a chemotherapeutic agent for the treatment of hepatocellular carcinoma (HCC). METHODS: BALB/c nude mice were randomized into four groups 24 h before subcutaneous injection of hepatocarcinoma BEL7402 cells suspended in phosphate buffered saline (PBS) into the right flank. The control group (n = 10) was fed a standard diet while treatment groups (n = 10 each) were fed a standard daily diet supplemented with different concentrations of UDCA (30, 50 and 70 mg/kg per day) for 21 d. Tumor growth was measured once each week, and tumor volume (V) was calculated with the following equation: V = (L × W2) × 0.52, where L is the length and W is the width of the xenograft. After 21 d, mice were killed under ether anesthesia, and tumors were excised and weighed. Apoptosis was evaluated through detection of DNA fragmentation with gel electrophoresis and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. Western blot analysis was performed to determine the expression of apoptosis-related proteins BAX, BCL2, APAF1, cleaved caspase-9, and cleaved caspase-3. RESULTS: UDCA suppressed tumor growth relative to controls. The mean tumor volumes were the following: control, 1090 ± 89 mm3; 30 mg/kg per day, 612 ± 46 mm3; 50 mg/kg per day, 563 ± 38 mm3; and 70 mg/kg per day, 221 ± 26 mm3. Decreased tumor volumes reached statistical significance relative to control xenografts (30 mg/kg per day, P < 0.05; 50 mg/kg per day, P < 0.05; 70 mg/kg per day, P < 0.01). Increasing concentrations of UDCA led to increased DNA fragmentation observed on gel electrophoresis and in the TUNEL assay (control, 1.6% ± 0.3%; 30 mg/kg per day, 2.9% ± 0.5%; 50 mg/kg per day, 3.15% ± 0.7%, and 70 mg/kg per day, 4.86% ± 0.9%). Western blot analysis revealed increased expression of BAX, APAF1, cleaved-caspase-9 and cleaved-caspase-3 proteins, which induce apoptosis, but decreased expression of BCL2

Obesity-associated inflammatory, metabolic, and endocrine mediators, as well as the functioning of the gut microbiota, are suspected to contribute to tumorigenesis. In obese people, proinflammatory cytokines/chemokines including tumor necrosis factor-alpha, interleukin (IL-1 and IL-6, insulin and insulin-like growth factors, adipokines, plasminogen activator inhibitor-1, adiponectin, and leptin are found to play crucial roles in the initiation and development of cancer. The cytokines induced by leptin in adipose tissue or tumor cells have been intensely studied. Leptin-induced signaling pathways are critical for biological functions such as adiposity, energy balance, endocrine function, immune reaction, and angiogenesis as well as oncogenesis. Leptin is an activator of cell proliferation and anti-apoptosis in several cell types, and an inducer of cancer stem cells; its critical roles in tumorigenesis are based on its oncogenic, mitogenic, proinflammatory, and pro-angiogenic actions. This review provides an update of the pathological effects of leptin signaling with special emphasis on potential molecular mechanisms and therapeutic targeting, which could potentially be used in future clinical settings. In addition, leptin-induced angiogenic ability and molecular mechanisms in HCC are discussed. The stringent binding affinity of leptin and its receptor Ob-R, as well as the highly upregulated expression of both

    2007-01-01

    Hepatocellular carcinoma is the most common cause of primary liver neoplasms and is one of the main causes of death in patients with liver cirrhosis. High Alpha fetoprotein serum levels have been found in 60–70% of patients with Hepatocellular carcinoma; nevertheless, there are other causes that increase this protein. Alpha fetoprotein levels ≥200 and 400 ng/mL in patients with an identifiable liver mass by imaging techniques are diagnostic of hepatocellular carcinoma with high specificity. We analysed the sensitivity and specificity of the progressive increase of the levels of alpha fetoprotein for the detection of hepatocellular carcinoma in patients with liver cirrhosis. Seventy-four patients with cirrhosis without hepatocellular carcinoma and 193 with hepatic lesions diagnosed by biopsy and shown by image scans were included. Sensitivity and specificity of transversal determination of alpha fetoprotein ≥ 200 and 400 ng/mL and monthly progressive elevation of alpha fetoprotein were analysed. Areas under the ROC curves were compared. Positive and negative predictive values adjusted to a 5 and 10% prevalence were calculated. For an elevation of alpha fetoprotein ≥ 200 and 400 ng/mL the specificity is of 100% in both cases, with a sensitivity of 36.3 and 20.2%, respectively. For an alpha fetoprotein elevation rate ≥7 ng/mL/month, sensitivity was of 71.4% and specificity of 100%. The area under the ROC curve of the progressive elevation was significantly greater than that of the transversal determination of alpha fetoprotein. The positive and negative predictive values modified to a 10% prevalence are of: 98.8% and 96.92%, respectively; while for a prevalence of 5% they were of 97.4% and 98.52%, respectively. The progressive elevation of alpha fetoprotein ≥7 ng/mL/month in patients with liver cirrhosis is useful for the diagnosis of hepatocellular carcinoma in patients that do not reach αFP levels ≥200 ng/mL. Prospective studies are required to

  10. Histological assessment of the efficacy of drug-eluting beads in portal tumor thrombosis of hepatocellular carcinoma

    Yusuke Imai, MD

    2017-03-01

    Full Text Available A 58-year-old man was diagnosed with advanced hepatocellular carcinoma with portal vein tumor thrombosis (PVTT. The tumors were multiple and existed in both lobes. Drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE was performed for the tumors in the left lobe. Embosphere and Hepasphere were selected for embolization of the arterioportal shunt, followed by loaded epirubicin infusion into the left hepatic artery. Computed tomography showed reduction of PVTT. However, liver failure progressed, and the patient died 67 days after DEB-TACE. Autopsy showed that the beads reached the tumor thrombosis in the portal vein. The prognosis of hepatocellular carcinoma with PVTT is poor. Although there are no established treatments for unresectable PVTT, DEB-TACE might be a useful option for such cases.

    2007-01-01

    Objective: To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF) and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF. Methods: One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results: Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF (the main stem of portal veins are visible). However, there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible). After the embolization, all of the 26 patients who have severe HAPVF stopped bleeding. Among them, the main stem of hepatic arteries are occluded in 2 patients. Conclusion: The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients, and it can be diagnosed through hepatic artery DSA. Orifice embolization is the most effective method for such kind of hemorrhage. (authors)

  12. Hepatocellular carcinoma with neuroendocrine differentiation: clinical and imaging findings in five patients

    Park, Seong Hoon; Kang, Myeong Jin; Cho, Jin Han

    2008-01-01

    To describe the clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation, which is an extremely rare variant of hepatocellular carcinoma. We collected five patients who had histopathologically proven hepatocellular carcinoma with neuroendocrine differentiation, and described morphologic feature, enhancement pattern of tumors, extrahepatic manifestation and clinical findings. At CT, the tumor size ranged from 8 to 17 cm (mean: 12 cm) in maximum diameter. The tumor margin was well-defined and smooth in four patients and all tumors were heterogeneously hypoattenuating. Four tumor showed rim enhancement on arterial and portal phases. Local invasion to the portal vein, intrahepatic duct and gallbladder were seen. Extrahepatic manifestations included hepatic metastases, lymph node metastasis. At ultrasonography, the tumor showed heterogeneously hyperechoic in all patients and hypoechoic rim was found in four patients. Of four patients who were followed up, one survived for 16 months after initial diagnosis, while the other three died within 3 months after initial diagnosis. As described above, clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation were not specific. However, this rare variant of hepatocellular carcinoma could be considered when hepatic tumor is found in an advanced stage and shows persistent rim enhancement at CT

    Hepatocellular carcinoma is a major public health problem with one of the highest overall mortality compared to other cancers. The median overall survival in France in a hospital population with hepatocellular carcinoma is 9.4 months. Several publications reported a positive impact of hepatocellular carcinoma screening on diagnosis at an early-stage, eligibility for curative treatment and overall survival. However, the identification of patients to be included in a hepatocellular carcinoma screening program and the application of screening recommendations are not optimal. Other studies suggest a potentially negative impact of delayed diagnosis or treatment initiation on the patient's prognosis. Finally, marked variations between French regions and departments have been described in terms of access to curative treatment and overall survival. In this review article, we propose a state of play of the hepatocellular carcinoma patient's care pathway in France with the aim of identifying potential breaking points with negative impact on prognosis and of developing proposals for improvement.

    2014-04-01

    Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies in the world whose chemoprevention became increasingly important in HCC treatment. Although the anticancer effects of asparagus constituents have been investigated in several cancers, its effects on hepatocellular carcinoma have not been fully studied. In this study, we investigated the anticancer effects of the deproteinized asparagus polysaccharide on the hepatocellular carcinoma cells using the in vitro and in vivo experimental model. Our data showed that deproteinized asparagus polysaccharide might act as an effective inhibitor on cell growth in vitro and in vivo and exert potent selective cytotoxicity against human hepatocellular carcinoma Hep3B and HepG2 cells. Further study showed that it could potently induce cell apoptosis and G2/M cell cycle arrest in the more sensitive Hep3B and HepG2 cell lines. Moreover, deproteinized asparagus polysaccharide potentiated the effects of mitomycin both in vitro and in vivo. Mechanistic studies revealed that deproteinized asparagus polysaccharide might exert its activity through an apoptosis-associated pathway by modulating the expression of Bax, Bcl-2, and caspase-3. In conclusion, deproteinized asparagus polysaccharide exhibited significant anticancer activity against hepatocellular carcinoma cells and could sensitize the tumoricidal effects of mitomycin, indicating that it is a potential therapeutic agent (or chemosensitizer) for liver cancer therapy.

  15. Mechanical Stress Promotes Cisplatin-Induced Hepatocellular Carcinoma Cell Death

    Full Text Available Cisplatin (CisPt is a commonly used platinum-based chemotherapeutic agent. Its efficacy is limited due to drug resistance and multiple side effects, thereby warranting a new approach to improving the pharmacological effect of CisPt. A newly developed mathematical hypothesis suggested that mechanical loading, when coupled with a chemotherapeutic drug such as CisPt and immune cells, would boost tumor cell death. The current study investigated the aforementioned mathematical hypothesis by exposing human hepatocellular liver carcinoma (HepG2 cells to CisPt, peripheral blood mononuclear cells, and mechanical stress individually and in combination. HepG2 cells were also treated with a mixture of CisPt and carnosine with and without mechanical stress to examine one possible mechanism employed by mechanical stress to enhance CisPt effects. Carnosine is a dipeptide that reportedly sequesters platinum-based drugs away from their pharmacological target-site. Mechanical stress was achieved using an orbital shaker that produced 300 rpm with a horizontal circular motion. Our results demonstrated that mechanical stress promoted CisPt-induced death of HepG2 cells (~35% more cell death. Moreover, results showed that CisPt-induced death was compromised when CisPt was left to mix with carnosine 24 hours preceding treatment. Mechanical stress, however, ameliorated cell death (20% more cell death.

  17. Value of radiofrequency ablation in the treatment of hepatocellular carcinoma

    Feng, Kai; Ma, Kuan-Sheng

    2014-01-01

    Hepatocellular carcinoma (HCC) is a malignant disease that substantially affects public health worldwide. It is especially prevalent in east Asia and sub-Saharan Africa, where the main etiology is the endemic status of chronic hepatitis B. Effective treatments with curative intent for early HCC include liver transplantation, liver resection (LR), and radiofrequency ablation (RFA). RFA has become the most widely used local thermal ablation method in recent years because of its technical ease, safety, satisfactory local tumor control, and minimally invasive nature. This technique has also emerged as an important treatment strategy for HCC in recent years. RFA, liver transplantation, and hepatectomy can be complementary to one another in the treatment of HCC, and the outcome benefits have been demonstrated by numerous clinical studies. As a pretransplantation bridge therapy, RFA extends the average waiting time without increasing the risk of dropout or death. In contrast to LR, RFA causes almost no intra-abdominal adhesion, thus producing favorable conditions for subsequent liver transplantation. Many studies have demonstrated mutual interactions between RFA and hepatectomy, effectively expanding the operative indications for patients with HCC and enhancing the efficacy of these approaches. However, treated tumor tissue remains within the body after RFA, and residual tumors or satellite nodules can limit the effectiveness of this treatment. Therefore, future research should focus on this issue. PMID:24876721

    2018-01-01

    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a major public health problem worldwide. Hepatocarcinogenesis is a complex multistep process at molecular, cellular, and histologic levels with key alterations that can be revealed by noninvasive imaging modalities. Therefore, imaging techniques play pivotal roles in the detection, characterization, staging, surveillance, and prognosis evaluation of HCC. Currently, ultrasound is the first-line imaging modality for screening and surveillance purposes. While based on conclusive enhancement patterns comprising arterial phase hyperenhancement and portal venous and/or delayed phase wash-out, contrast enhanced dynamic computed tomography and magnetic resonance imaging (MRI) are the diagnostic tools for HCC without requirements for histopathologic confirmation. Functional MRI techniques, including diffusion-weighted imaging, MRI with hepatobiliary contrast agents, perfusion imaging, and magnetic resonance elastography, show promise in providing further important information regarding tumor biological behaviors. In addition, evaluation of tumor imaging characteristics, including nodule size, margin, number, vascular invasion, and growth patterns, allows preoperative prediction of tumor microvascular invasion and patient prognosis. Therefore, the aim of this article is to review the current state-of-the-art and recent advances in the comprehensive noninvasive imaging evaluation of HCC. We also provide the basic key concepts of HCC development and an overview of the current practice guidelines. PMID:29904242

  19. Factors associated with tumor size of hepatocellular carcinoma

    Determining the association of age and laboratory parameters with tumor size of hepatocellular carcinoma (HCC). The study was at Adam Malik Hospital Medan from June- December 2016. 100 HCC patients were enrolled; those with excluding liver metastatic. Baseline characteristics of gender, age, obtaining etiology of HCC. Liver function tests, viral marker, and INR were done. Based on tumor size from abdomen CT, patients were three groups: tumor size below 3 cm, 3-5 cm, and above 5 cm size. Patients were also divided based on Child-Pugh class. Correlation of age and laboratory results with tumor size of HCC patients were analyzed. Age have negative correlation with tumor size in HCC patients (r=-0.297, p=0.032) while AFP have positive correlation with tumor size (r0.446, p=<0.001). Total bilirubin, AST, and ALT have negative correlation but non-significant (r=-0.045, -0.078, - 0.126 respectively). Albumin and INR have positive correlation but non-significant (r=0.021, 0.112 respectively). Our study suggests that older age correlates with smaller tumor size, while AFP level has a significant correlation with tumor size in HCC patients. AFP level may be a useful marker for determining the prognosis of HCC patients.

  20. Recent advances in multidisciplinary management of hepatocellular carcinoma

    Gomaa, Asmaa I; Waked, Imam

    2015-01-01

    The incidence of hepatocellular carcinoma (HCC) is increasing, and it is currently the second leading cause of cancer-related death worldwide. Potentially curative treatment options for HCC include resection, transplantation, and percutaneous ablation, whereas palliative treatments include trans-arterial chemoembolization (TACE), radioembolization, and systemic treatments. Due to the diversity of available treatment options and patients’ presentations, a multidisciplinary team should decide clinical management of HCC, according to tumor characteristics and stage of liver disease. Potentially curative treatments are suitable for very-early- and early-stage HCC. However, the vast majority of HCC patients are diagnosed in later stages, where the tumor characteristics or progress of liver disease prevent curative interventions. For patients with intermediate-stage HCC, TACE and radioembolization improve survival and are being evaluated in addition to potentially curative therapies or with systemic targeted therapy. There is currently no effective systemic chemotherapy, immunologic, or hormonal therapy for HCC, and sorafenib is the only approved molecular-targeted treatment for advanced HCC. Other targeted agents are under investigation; trials comparing new agents in combination with sorafenib are ongoing. Combinations of systemic targeted therapies with local treatments are being evaluated for further improvements in HCC patient outcomes. This article provides an updated and comprehensive overview of the current standards and trends in the treatment of HCC. PMID:25866604

  1. Tissue- and Serum-Associated Biomarkers of Hepatocellular Carcinoma

    Chauhan, Ranjit; Lahiri, Nivedita

    2016-01-01

    Hepatocellular carcinoma (HCC), one of the leading causes of cancer deaths in the world, is offering a challenge to human beings, with the current modes of treatment being a palliative approach. Lack of proper curative or preventive treatment methods encouraged extensive research around the world with an aim to detect a vaccine or therapeutic target biomolecule that could lead to development of a drug or vaccine against HCC. Biomarkers or biological disease markers have emerged as a potential tool as drug/vaccine targets, as they can accurately diagnose, predict, and even prevent the diseases. Biomarker expression in tissue, serum, plasma, or urine can detect tumor in very early stages of its development and monitor the cancer progression and also the effect of therapeutic interventions. Biomarker discoveries are driven by advanced techniques, such as proteomics, transcriptomics, whole genome sequencing, micro- and micro-RNA arrays, and translational clinics. In this review, an overview of the potential of tissue- and serum-associated HCC biomarkers as diagnostic, prognostic, and therapeutic targets for drug development is presented. In addition, we highlight recently developed micro-RNA, long noncoding RNA biomarkers, and single-nucleotide changes, which may be used independently or as complementary biomarkers. These active investigations going on around the world aimed at conquering HCC might show a bright light in the near future. PMID:27398029

    Hepatocellular carcinoma (HCC) is the most rapidly increasing type of cancer in the United States. HCC is a highly malignant cancer, accounting for at least 14000 deaths in the United States annually, and it ranks third as a cause of cancer mortality in men. One major difficulty is that most patients with HCC are diagnosed when the disease is already at an advanced stage, and the cancer cannot be surgically removed. Furthermore, because almost all patients have cirrhosis, neither chemotherapy nor major resections are well tolerated. Clearly there is need of a multidisciplinary approach for the management of HCC. For example, there is a need for better understanding of the fundamental etiologic mechanisms that are involved in hepatocarcinogenesis, which could lead to the development of successful preventive and therapeutic modalities. It is also essential to define the cellular and molecular bases for malignant transformation of hepatocytes. Such knowledge would: (1) greatly facilitate the identification of patients at risk; (2) prompt efforts to decrease risk factors; and (3) improve surveillance and early diagnosis through diagnostic imaging modalities. Possible benefits extend also to the clinical management of this disease. Because there are many factors involved in pathogenesis of HCC, this paper reviews a multidisciplinary perspective of recent advances in basic and clinical understanding of HCC that include: molecular hepatocarcinogenesis, non-invasive diagnostics modalities, diagnostic pathology, surgical modality, transplantation, local therapy and oncological/target therapeutics.

    Dynamic computed tomography (CT) scans in 65 hepatocellular carcinomas were analyzed and compared to plain and drip infusion contrast CT scans of those. Scans were obtained before, 10, 30, and 50 seconds after an intravenous bolus injection of 50ml 65% Angiografin. By this method, 49 hepatomas had moderate to marked enhancement at the arterial phase while the enhancement of normal liver parenchyma was only slight at the arterial phase and peaked at the portal phase. Compared to a drip infusion contrast CT, a dynamic CT had advantages to detect an isodense hepatoma in 4 and daughter tumors in 16 both of which were not appreciated by a plain and a drip infusion contrast CT. The tumor extension was also better delineated by a dynamic CT because a part of hepatoma had an isodense area. An arterio-portal shunt was visualized in one. Tumor thrombus in the portal vein was clearly demonstrated in 6 at the portal phase of a dynamic CT. Since a dynamic CT is convenient to perform without any special program or soft wear and gives us very useful information, we believe that it should be routinely employed as a part of a liver CT examination.

  4. Guide for diagnosis and treatment of hepatocellular carcinoma

    Attwa, Magdy Hamed; El-Etreby, Shahira Aly

    2015-01-01

    Hepatocellular carcinoma (HCC) is ranked as the 5th common type of cancer worldwide and is considered as the 3rd common reason for cancer-related deaths. HCC often occurs on top of a cirrhotic liver. The prognosis is determined by several factors; tumour extension, alpha-fetoprotein (AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient’s performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis. Many tumour markers have been tested in clinical trials without progressing to routine use in clinical practice. Thus, surveillance is still based on ultrasound (US) examination every 6 mo. Imaging studies for diagnosis of HCC can fall into one of two main categories: routine non-invasive studies such as US, computed tomography (CT), and magnetic resonance imaging, and more specialized invasive techniques including CT during hepatic arteriography and CT arterial portography in addition to the conventional hepatic angiography. This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC. PMID:26140083

  5. A Surgical Perspective on Targeted Therapy of Hepatocellular Carcinoma

    Faltermeier, Claire; Busuttil, Ronald W.; Zarrinpar, Ali

    2015-01-01

    Hepatocellular carcinoma (HCC), the second leading cause of cancer deaths worldwide, is difficult to treat and highly lethal. Since HCC is predominantly diagnosed in patients with cirrhosis, treatment planning must consider both the severity of liver disease and tumor burden. To minimize the impact to the patient while treating the tumor, techniques have been developed to target HCC. Anatomical targeting by surgical resection or locoregional therapies is generally reserved for patients with preserved liver function and minimal to moderate tumor burden. Patients with decompensated cirrhosis and small tumors are optimal candidates for liver transplantation, which offers the best chance of long-term survival. Yet, only 20%–30% of patients have disease amenable to anatomical targeting. For the majority of patients with advanced HCC, chemotherapy is used to target the tumor biology. Despite these treatment options, the five-year survival of patients in the United States with HCC is only 16%. In this review we provide a comprehensive overview of current approaches to target HCC. We also discuss emerging diagnostic and prognostic biomarkers, novel therapeutic targets identified by recent genomic profiling studies, and potential applications of immunotherapy in the treatment of HCC.

  6. Radiofrequency ablation of hepatocellular carcinoma: pros and cons.

    Rhim, Hyunchul; Lim, Hyo K

    2010-09-01

    Among locoregional treatments for hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) has been accepted as the most popular alternative to curative transplantation or resection, and it shows an excellent local tumor control rate and acceptable morbidity. The benefits of RFA have been universally validated by the practice guidelines of international societies of hepatology. The main advantages of RFA include 1) it is minimally invasive with acceptable morbidity, 2) it enables excellent local tumor control, 3) it has promising long-term survival, and 4) it is a multimodal approach. Based on these pros, RFA will play an important role in managing the patient with early HCC (smaller than 3 cm with fewer than four tumors). The main limitations of current RFA technology in hepatic ablation include 1) limitation of ablation volume, 2) technically infeasible in some tumors due to conspicuity and dangerous location, and 3) the heat-sink effect. Many technical approaches have been introduced to overcome those limitations, including a novel guiding modality, use of artificial fluid or air, and combined treatment strategies. RFA will continue to play a role as a representative ablative modality in the management of HCC, even in the era of targeted agents.

    2001-01-01

    The objective of this study was to determine which of the following three methods is the most effective for the treatment of bone metastases from hepatocellular carcinoma (HCC): transcatheter arterial embolization (TAE); combination of TAE and external radiotherapy; or external radiotherapy alone. Thirty-nine metastatic bone lesions from HCC in 33 patients were retrospectively reviewed. Each lesion underwent either TAE alone (group A, n=11), TAE followed by radiotherapy (group B, n=17), or radiotherapy alone (group C, n=11). They were evaluated on the following subjects: pain relief; improvement of daily activities; and complications. Each treatment was effective for pain relief (89-94%) and improvement of daily activities (73-82%). The mean time interval from the beginning of each treatment to the onset of initial pain relief was 4.7 days in group A, 4.8 days in group B, and 15 days in group C. Recurrence of the pain after the initial pain relief was noted in 75% in group A, 20% in group B, and 88% in group C. Pyrexia and local pain commonly occurred after TAE. In conclusion, TAE is effective in relieving pain immediately and in improving the patients' daily activities. The combination of TAE and radiotherapy is recommended for permanent pain relief.

  8. Regorafenib for the treatment of unresectable hepatocellular carcinoma.

    Rimassa, Lorenza; Pressiani, Tiziana; Personeni, Nicola; Santoro, Armando

    2017-07-01

    Sorafenib is the standard of care for patients with advanced hepatocellular carcinoma (HCC) and well preserved liver function. However, until recent approval of regorafenib by the Food and Drug Administration (FDA), no effective therapeutic options were available for patients resistant to sorafenib. Areas covered: The present article reviews the preclinical and clinical data of regorafenib, putting them into the context of current and future landscape of treatment options for patients with HCC. Recently, the randomized, placebo-controlled, Phase III RESORCE trial, demonstrated a statistically and clinically significant increase in overall survival from 7.8 months with placebo to 10.6 months with regorafenib in patients progressing on sorafenib. Furthermore, the study showed a significant improvement in all the other efficacy endpoints. Main adverse events were hypertension, hand-foot skin reaction, fatigue and diarrhea, with no negative impact on quality of life. Expert commentary: Regorafenib is a recently approved treatment option for HCC patients who have been previously treated with sorafenib. The RESORCE trial demonstrates the beneficial effect of a sequential approach involving two multikinase inhibitors, namely sorafenib and regorafenib, whose antitumor activity extends beyond their antiangiogenic functions.

    Purpose Multikinase growth inhibitors inhibit their target kinases with varying potency. Patients often require lower doses or therapy breaks due to drug toxicities. To evaluate the effects of drug withdrawal on hepatocellular carcinoma cells after incubation with growth-inhibitory concentrations of regorafenib, cell growth, migration and invasion, and signaling were examined. Methods Cell proliferation, motility, and invasion were analyzed by MTT, wound healing, and invasion assays, respectively, and MAPK pathway protein markers were analyzed by Western blot. Results After regorafenib removal, cell growth, migration, and invasion recovered. Repeated drug exposure resulted in changes in cell growth patterns. Recovery could be blocked by sub-growth-inhibitory concentrations of either doxorubicin or vitamin K1. Recovery of growth was associated with increased phospho-JNK, phospho-p38, and phospho-STAT3 levels. The recovery of growth, migration, and signaling were blocked by a JNK inhibitor. Conclusions Removal of regorafenib from growth-inhibited cells resulted in a JNK-dependent recovery of growth and migration. PMID:23959464

  10. Regorafenib delays the proliferation of hepatocellular carcinoma by inducing autophagy.

    Han, Rui; Li, Shixin

    2018-04-02

    The aim of the present study was to investigate the effects of regorafenib on hepatocellular carcinoma autophagy, thereby supressing the malignancy of HCC. First, HepG2 and Hep3B cell autophagy was investigated using GFP-LC3 transfection after the treatment of regorafenib. Then, the activation of Akt/mTOR signaling was analyzed using western blot. Our data showed that liver cancer cell autophagy was significantly induced by 20 μM regorafenib using GFP-LC3 transfection. Meanwhile, regorafenib-induced cell death could largely be abolished by 3-MA or CQ treatment, suggesting that regorafenib-induced HepG2 cell death was partially dependent on autophagy. Moreover, the activation of Akt/mTOR signaling was inhibited by regorafenib pre-incubation. MTT assay showed the combination use of regorafenib and CDDP led to a stronger growth inhibitory effect on HepG2 and Hep3B cells. In summary, regorafenib may acts an adjunctive therapy for liver cancer patients via modulating autophagy-dependent cell death even when apoptosis resistance is induced in cancer cells.

  11. ANGIOGENESIS INHIBITORS FOR THE TREATMENT OF HEPATOCELLULAR CARCINOMA

    Massimiliano Berretta

    2016-11-01

    Full Text Available Background: Angiogenesis inhibitors have become an important therapeutic approach in the treatment of hepatocellular carcinoma (HCC patients. The achievement of Sorafenib in prolonging overall survival of patients with HCC makes therapeutic inhibition of angiogenesis a fundamental element of the treatment of HCC. Considering the heterogeneous aspects of HCC and to enhance therapeutic efficacy, overcome drug resistance and reduce toxicity, the combination of antiangiogenic drugs with antiblastic chemotherapy (AC, radiotherapy or other targeted drugs have been evaluated. The issue is further complicated by the combination of antiangiogenesis with other AC or biologic drugs. To date, there is no planned approach to determine which patients are more responsive to a given type of antiangiogenic treatment. Conclusion: Large investments in the clinical research are essential to improve treatment response and minimize toxicities for patients with HCC. Future investigations will need to focus on utilizing patterns of genetic information to classify HCC into groups that display similar prognosis and treatment sensitivity, and combining targeted therapies with AC producing enhanced anti-tumor effect. In this review the current panel of available antiangiogenic therapies for the treatment of HCC have been analyzed. In addition current clinical trials are also reported herein.

  12. Transarterial chemoembolization with drug-eluting beads in hepatocellular carcinoma

    Nam, Hee Chul; Jang, Bohyun; Song, Myeong Jun

    2016-01-01

    Transarterial chemoembolization (TACE) is a widely used standard treatment for patients with hepatocellular carcinoma (HCC) who are not suitable candidates for curative treatments. The rationale for TACE is that intra-arterial chemotherapy using lipiodol and chemotherapeutic agents, followed by selective vascular embolization, results in a strong cytotoxic effect as well as ischemia (conventional TACE). Recently, drug-eluting beads (DC Beads®) have been developed for transcatheter treatment of HCC to deliver higher doses of the chemotherapeutic agent and to prolong contact time with the tumor. DC Beads® can actively sequester doxorubicin hydrochloride from solution and release it in a controlled sustained fashion. Treatment with DC Beads® substantially reduced the amount of chemotherapeutic agent that reached the systemic circulation compared with conventional, lipiodol-based regimens, significantly reducing drug-related adverse events. In this article, we describe the treatment response, survival, and safety of TACE used with drug-eluting beads for the treatment of HCC and discuss future therapeutic possibilities. PMID:27833376

    This study aimed to evaluate the initial outcomes of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in terms of tumor response and safety. HCC patients who were not indicated for standard curative local modalities and who were treated with PBT at Samsung Medical Center from January 2016 to February 2017 were enrolled. Toxicity was scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was evaluated using modified Response Evaluation Criteria in Solid Tumors (mRECIST). A total of 101 HCC patients treated with PBT were included. Patients were treated with an equivalent dose of 62-92 GyE 10 . Liver function status was not significantly affected after PBT. Greater than 80% of patients had Child-Pugh class A and albumin-bilirubin (ALBI) grade 1 up to 3-months after PBT. Of 78 patients followed for three months after PBT, infield complete and partial responses were achieved in 54 (69.2%) and 14 (17.9%) patients, respectively. PBT treatment of HCC patients showed a favorable infield complete response rate of 69.2% with acceptable acute toxicity. An additional follow-up study of these patients will be conducted.

    Mu, Lin; Chapiro, Julius; Stringam, Jeremiah; Geschwind, Jean-François

    The clinical management of hepatocellular carcinoma has evolved greatly in the last decade mostly through recent technical innovations. In particular, the application of cutting-edge image guidance has led to minimally invasive solutions for complex clinical problems and rapid advances in the field of interventional oncology. Many image-guided therapies, such as transarterial chemoembolization and radiofrequency ablation, have meanwhile been fully integrated into interdisciplinary clinical practice, whereas others are currently being investigated. This review summarizes and evaluates the most relevant completed and ongoing clinical trials, provides a synopsis of recent innovations in the field of intraprocedural imaging and tumor response assessment, and offers an outlook on new technologies, such as radiopaque embolic materials. In addition, combination therapies consisting of locoregional therapies and systemic molecular targeted agents (e.g., sorafenib) remain of major interest to the field and are also discussed. Finally, we address the many substantial advances in immune response pathways that have been related to the systemic effects of locoregional therapies. Knowledge of these new developments is crucial as they continue to shape the future of cancer treatment, further establishing interventional oncology along with surgical, medical, and radiation oncology as the fourth pillar of cancer care.

    CC chemokine receptor 1 (CCR1) has an important role in the recruitment of leukocytes to the site of inflammation. The migration and metastasis of tumor cells shares many similarities with leukocyte trafficking, which is mainly regulated by chemokine receptor-ligand interactions. CCR1 is highly expressed in hepatocellular carcinoma (HCC) cells and tissues with unknown functions. In this study, we silenced CCR1 expression in the human HCC cell line HCCLM3 using artificial microRNA (miRNA)-mediated RNA interference (RNAi) and examined the invasiveness and proliferation of CCR1-silenced HCCLM3 cells and the matrix metalloproteinase (MMP) activity. The miRNA-mediated knockdown expression of CCR1 significantly inhibited the invasive ability of HCCLM3 cells, but had only a minor effect on the cellular proliferation rate. Moreover, CCR1 knockdown significantly reduced the secretion of MMP-2. Together, these findings indicate that CCR1 has an important role in HCCLM3 invasion and that CCR1 might be a new target of HCC treatment

    2017-11-01

    Full Text Available Background: The aim of this study was to characterize the disorder of lipid metabolism in hepatocellular carcinoma (HCC. HCC is a worldwide disease. The research into the disorder of lipid metabolism in HCC is very limited. Study of lipid metabolism in liver cancer tissue may have the potential to provide new insight into HCC mechanisms. Methods: A lipidomics study of HCC based on Ultra high performance liquid chromatography-electronic spray ionization-QTOF mass spectrometer (UPLC-ESI-QTOF MS and Matrix assisted laser desorption ionization-fourier transform ion cyclotron resonance mass spectrometer (MALDI-FTICR MS was performed. Results: Triacylglycerols (TAGs with the number of double bond (DB > 2 (except 56:5 and 56:4 TAG were significantly down-regulated; conversely, others (except 52:2 TAG were greatly up-regulated in HCC tissues. Moreover, the more serious the disease was, the higher the saturated TAG concentration and the lower the polyunsaturated TAG concentration were in HCC tissues. The phosphatidylcholine (PC, phosphatidylethanolamine (PE and phosphatidylinositol (PI were altered in a certain way. Sphingomyelin (SM was up-regulated and ceramide (Cer were down-regulated in HCC tissues. Conclusions: To our knowledge, this is the first such report showing a unique trend of TAG, PC, PE and PI. The use of polyunsaturated fatty acids, like eicosapentanoic and docosahexanoic acid, as supplementation, proposed for the treatment of Non-alcoholic steatohepatitis (NASH, may also be effective for the treatment of HCC.

  17. Research advances in proton beam therapy for hepatocellular carcinoma

    Full Text Available Hepatocellular carcinoma (HCC, one of the most common malignancies with high prevalence and mortality rate, usually results in poor prognosis and limited survival. A comprehensive analysis on the number and location of tumors, Child-Pugh grade, and Barcelona Clinic Liver Cancer stage will help the development of suitable treatment programs and improve prediction of prognosis. A majority of patients are complicated by cirrhosis, enlarged tumor, multiple lesions, vascular invasion, and even cancer embolus in the portal vein. With the growth of knowledge about the radiation tolerance of normal tissue and the advances in radiotherapy techniques, radiotherapy has become an important tool for step-down therapy and adjuvant therapy for liver cancer. Proton beam therapy (PBT is emerging as a novel radiotherapy for the management of HCC, which, benefiting from the effect of Bragg Peak from PBT, effectively decreases the toxicity of traditional radiotherapies to the liver and does little harm to the uninvolved liver tissue or the surrounding structures while intensifying the destruction in targeted malignant lesions. Furthermore, several previous studies on the treatment of HCC with PBT revealed excellent local control. The distinctive biophysical attributes of PBT in the treatment of HCC, as well as the available literature regarding clinical outcomes and toxicity of using PBT for HCC, are reviewed. Current evidence provides limited indications for PBT, which suggests that further study on the relationship between liver function and PBT is required to gain further insight into its indication and standardization.

    Full Text Available The role of podoplanin in hepatocellular carcinoma (HCC is not clear yet. The aim of our study was to evaluate the expression of podoplanin in HCC and to determine its role in hepatocarcinogenesis. We performed immunohistochemistry with monoclonal D2-40 antibody, on paraffin-embedded tissue sections of 72 patients diagnosed with HCC. Lymphatic vessels density (LVD was increased in patients who had vascular invasion at the time of diagnosis (P=0.018 and in those with associated cirrhosis (P=0.006. Tumor cells showing podoplanin expression were correlated with histological grade (P=0.040. Podoplanin-expressing cancer associated fibroblasts (CAFs were correlated with both LVD (P=0.019 and tumor cells (P=0.015. Our results sustain the dual role of podoplanin in HCC by its involvement in both HCC tumorigenesis, lymphatic neovascularization and tumor invasion invasiveness. A possible crosstalk between epithelial and stromal tumor cells in HCC tumor microenvironment may be mediated by podoplanin, but this hypothesis needs further studies to elucidate this interrelation.

    2010-09-01

    Orthotopic liver transplantation (OLT) is the best treatment option for selected patients with hepatocellular carcinoma (HCC) with the background of cirrhosis since this treatment modality can cure both diseases at once. Over the years, the applicability of OLT for HCC has evolved. In Asia, including Hong Kong, a shortage of deceased donor liver grafts is a universal problem having to be faced in all transplant centers. Living-donor liver transplant (LDLT) has therefore been developed to counteract organ shortage and the high prevalence of HCC. The application of LDLT for HCC is a complex process involving donor voluntarism, selection criteria for the recipient and justification with respect to long-term survival in comparison to the result of deceased donor liver transplant. This article reviews the authors' experience with OLT for HCC patients in Hong Kong, with emphasis on the applicability and outcome of LDLT for HCC. Donor voluntarism has a significant impact on the application of LDLT. "Fast-track" LDLT in the setting of recurrence following curative treatment carries a high risk of recurrence even though the tumor stage fulfills the standard criteria. Although the survival outcome may be worse following LDLT than DDLT for HCC, LDLT is still the main treatment option for patients with transplantable HCC in Hong Kong, and a reasonable survival outcome can be achieved in selected patients with extended indications. It is particularly true that LDLT provides the only hope for patients with advanced HCC under the constricting problem of organ shortage.

    Adrenal metastases (AM) from hepatocellular carcinoma (HCC) are rarely seen in clinical practice. The treatment is not standardized, the indications and efficacy of different therapeutic approaches being still controversial. Between January 1995 and December 2005, 174 patients underwent liver resection for HCC in our center. AM were detected in four patients (2.3%): three of them had HCC and synchronous AM, and the remaining one developed AM 10 months after liver resection. All the patients with AM were treated by adrenalectomy (simultaneously with liver resection in synchronous metastases), followed by systemic chemotherapy. Non-resectable multifocal liver recurrences occurred in two patients, one of them having also a contralateral adrenal metastasis; these two patients are presently alive 26 and 43 months after adrenalectomy, respectively. Another patient died by liver recurrence 27 months postoperatively. The fourth patient is disease-free at 17 months after the initial operation. Adrenalectomy for AM from HCC should be performed whenever the primary tumor is well therapeutically controlled and the patient has a good performance status. Adrenalectomy offers the chance of more than 2 years survival in many patients. However, once AM are detected, the prognosis remains poor.

  2. Changes in arginase isoenzymes pattern in human hepatocellular carcinoma

    Chrzanowska, Alicja; Krawczyk, Marek; Baranczyk-Kuzma, Anna

    2008-01-01

    Hepatocellular carcinoma (HCC) is one of the most common tumors worldwide affecting preferentially patients with liver cirrhosis. The studies were performed on tissues obtained during surgery from 50 patients with HCC, 40 with liver cirrhosis and 40 control livers. It was found that arginase activity in HCC was nearly 5- and 15-fold lower than in cirrhotic and normal livers, respectively. Isoenzymes AI (so-called liver-type arginase) and AII (extrahepatic arginase) were identified by Western blotting in all studied tissues, however the amount of AI, as well as the expression of AI-mRNA were lower in HCC, in comparison with normal liver, and those of AII were significantly higher. Since HCC is arginine-dependent, and arginine is essential for cells growth, the decrease of AI may preserve this amino acid within tumor cells. Concurrently, the rise of AII can increase the level of polyamines, compounds crucial for cells proliferation. Thus, both arginase isoenzymes seem to participate in liver cancerogenesis.

  3. Improving clinical trial design for hepatocellular carcinoma treatments

    Robert G. Gish

    2011-12-01

    Full Text Available Despite its place as the third leading cause of cancer deaths worldwide, there are currently no approved chemotherapeutic agents, devices or techniques to treat hepatocellular carcinoma. Importantly, there have been no phase III studies demonstrating survival benefit, nor any randomized studies of treatment except for transarterial chemoembolization and most recently sorafenib. The importance of well-designed clinical trials of agents to treat HCC has never been greater. However, general clinical study design issues, combined with HCC-specific issues pose significant challenges in structuring such studies. HCC-related challenges include the heterogeneity of this cancer and the fact that it is frequently accompanied by significant comorbidities at diagnosis, such as active hepatitis B or C virus replication, substantial past or on-going alcohol use, and cirrhosis, itself often a fatal disease. The recently published comparison of a newer treatment, nolatrexed to doxorubicin, and comments about this study’s initial HCC diagnostic criteria, staging system, comparator therapy and choice of endpoints have provided a platform to discuss the challenges unique to the design of HCC clinical trials. The difficulty in accurately framing study results obtained from the constantly changing HCC clinical landscape and approaches to meet these challenges will be reviewed.

    1986-06-01

    Single-photon emission computed tomography (SPECT) performed using a rotating gamma camera was compared with ..cap alpha../sub 1/-fetoprotein (AFP) assay, conventional liver scintigraphy, ultrasound (US) imaging, computed tomography (CT), and selective celiac angiography in 40 patients with a total of 50 small hepatocellular carcinomas (HCCs;<5 cm). The detection rates of US and CT were determined on an initial screening study and on a second, more precisely focused study. The detection rate of small HCCs by the various modalities was as follows: AFP, 13%; liver scintigraphy, 36%; SPECT, 72%; initial screening US, 80%; second, more precise US studies, 94%; initial screening CT, 64%; second, more precise CT study, 82%; angiography, 88%. Although SPECT was inferior to the initial screening US examination in detecting HCCs less than 2 cm in size, its sensitivity was identical to that of the initial screening US study for detecting HCCs of 2-5 cm. The combination of SPECT and US was an excellent method for the early detection of HCCs, yielding a detection rate of 94%.

  5. Transcatheter Arterial Chemoembolization Based on Hepatic Hemodynamics for Hepatocellular Carcinoma

    2013-01-01

    Full Text Available Hepatocellular carcinoma (HCC is the sixth most common cancer and the third leading cause of cancer-related deaths in the world. The Barcelona Clinic Liver Cancer (BCLC classification has recently emerged as the standard classification system for clinical management of patients with HCC. According to the BCLC staging system, curative therapies (resection, transplantation, and percutaneous ablation can improve survival in HCC patients diagnosed at an early stage and offer potential long-term curative effects. Patients with intermediate-stage HCC benefit from transcatheter arterial chemoembolization (TACE, and those diagnosed at an advanced stage receive sorafenib, a multikinase inhibitor, or conservative therapy. Most patients receive palliative or conservative therapy only, and approximately 50% of patients with HCC are candidates for systemic therapy. TACE is often recommended for advanced-stage HCC patients all over the world because these patients desire therapy that is more effective than systemic chemotherapy or conservative treatment. This paper aims to summarize both the published data and important ongoing studies for TACE and to discuss technical improvements in TACE for advanced-stage HCC.

    To evaluate the effect of radiotherapy (RT) on hepatocellular carcinoma (HCC) that appears as a solitary nodule on radiologic studies. We irradiated 17 patients with solitary HCC lesions (25-150 mm in diameter) with approximately 60 Gy (range 50-70 Gy). Patients underwent dynamic CT and/or ultrasound imaging at 3-month intervals after treatment. Patients were classified based on lesion size, degree of cirrhosis (Child A. 6; Child B, 6; Child C, 5), and whether they had received other therapy such as transarterial chemoembolization (TACE). The responses were classified as complete, partial, no change, or progression. The median survival was 12.8 months for all 17 patients, with 1-, 2-, and 3-year cumulative survival rates of 59%, 35% and 24%, respectively. Patients classified as Child A showed significantly longer survival than those classified as either Child B (p<0.04) or C (p<0.01). Four of the five Child C patients died of liver failure within 6 months after RT despite the absence of tumor recurrence. The initial tumor diameter, concurrent treatment with TACE, and radiation dose showed no significant effect on survival. Survival in patients with solitary HCC lesions appears to be affected mainly by the degree of liver dysfunction, and not the initial tumor diameter, radiation dose, or concurrent use of TACE.

    2016-01-01

    Full Text Available Hepatocellular carcinoma (HCC, one of the leading causes of cancer deaths in the world, is offering a challenge to human beings, with the current modes of treatment being a palliative approach. Lack of proper curative or preventive treatment methods encouraged extensive research around the world with an aim to detect a vaccine or therapeutic target biomolecule that could lead to development of a drug or vaccine against HCC. Biomarkers or biological disease markers have emerged as a potential tool as drug/vaccine targets, as they can accurately diagnose, predict, and even prevent the diseases. Biomarker expression in tissue, serum, plasma, or urine can detect tumor in very early stages of its development and monitor the cancer progression and also the effect of therapeutic interventions. Biomarker discoveries are driven by advanced techniques, such as proteomics, transcriptomics, whole genome sequencing, micro- and micro-RNA arrays, and translational clinics. In this review, an overview of the potential of tissue- and serum-associated HCC biomarkers as diagnostic, prognostic, and therapeutic targets for drug development is presented. In addition, we highlight recently developed micro-RNA, long noncoding RNA biomarkers, and single-nucleotide changes, which may be used independently or as complementary biomarkers. These active investigations going on around the world aimed at conquering HCC might show a bright light in the near future.

    Hepatocellular carcinoma (HCC) ranks second amongst all causes of cancer deaths globally. It is on a rise in Pakistan and might represent the most common cancer in adult males. Pakistan contributes significantly to global burden of hepatitis C, which is a known risk factor for HCC, and has one of the highest prevalence rates (>3%) in the world. In the absence of a national cancer registry and screening programs, prevalence of hepatitis and HCC only represents estimates of the real magnitude of this problem. In this review, we present various aspects of HCC in Pakistan, comparing and contrasting it with the global trends in cancer care. There is a general lack of awareness regarding risk factors of HCC in Pakistani population and prevalence of hepatitis C has increased. In addition, less common risk factors are also on a rise. Majority of patients present with advanced HCC and are not eligible for definitive treatment. We have attempted to highlight issues that have a significant bearing on HCC outcome in Pakistan. A set of strategies have been put forth that can potentially help reduce incidence and improve HCC outcome on national level. PMID:26955390

    2013-01-01

    Yttrium-90 microspheres are radioactive particles which are increasingly being employed for treating patients with unresectable hepatocellular carcinoma (HCC). The procedure is called radioembolization. It involves the injection of micron-sized embolic particles loaded with a radioisotope by use of transarterial techniques. Because of the sensitivity of liver parenchyma and relative insensitivity of tumor, external radiation has played a limited role in treating HCC. (90)Y administered via arterial route directs the highly concentrated radiation to the tumor while healthy liver parenchyma is relatively spared due to its preferential blood supply from portal venous blood. This technique has proven useful for the majority of patients with HCC as most of them present in advanced stage, beyond potentially curative options (resection/liver transplantation). (90)Y microspheres can be used in downstaging large tumors to bring within transplantable criteria, in patients with portal venous thrombosis due to tumor invasion and as palliative therapy. There are two available devices for (90)Y administration; TheraSphere® (glass based) and SIR-Spheres® (resin based). The procedure is performed on an outpatient basis. The incidence of complications is comparatively less and may include nausea, fatigue, abdominal pain, hepatic dysfunction, biliary injury, fibrosis, radiation pneumonitis, GI ulcers, and vascular injury; however, these can be avoided by meticulous pretreatment assessment, careful patient selection, and adequate dosimetry. This article explores the technical and clinical aspects of (90)Y radioembolization with keeping emphasis on patient selection, uses, and complications.

    In the world the hepatocellular carcinoma (HCC) is the fifth to sixth most common malignancy. An increase in its incidence is looming in Cuba as a result of the population aging and the increase of morbi-mortality due to liver cirrhosis (CH). α-fetoprotein (AFP) by SUMA®, was used in this work as a tumor marker technique in 189 Cirrhotic patients evaluated at the CIMEQ, between January 1999 and September 2005. The main factors associated with an elevation of AFP were HCC, viral cirrhosis, and the age of 50 years or more. Presented CHC 22 (11.64%) patients, who had an average age of 55 years and the predominant sex was male (86,36%). The most important cause associated with this malignant disease was viral CH, mainly the virus of hepatitis C. This tumor marker showed a sensitivity and specificity of 68.18% and 92.17%, respectively. When combined with abdominal ultrasound was increase 86.36% sensitivity and 100% specificity. Elevated AFP levels associated with tumor prognosis factors. It can be concluded that the AFP had value in the diagnosis of HCC. This work is the first of its kind carried out in Cuba, and allows the design of a workable strategy for the research, monitoring and prognosis of HCC, having a wide network of laboratories SUMA®,, with a low cost per each determination.

  12. A Surgical Perspective on Targeted Therapy of Hepatocellular Carcinoma

    Claire Faltermeier

    2015-09-01

    Full Text Available Hepatocellular carcinoma (HCC, the second leading cause of cancer deaths worldwide, is difficult to treat and highly lethal. Since HCC is predominantly diagnosed in patients with cirrhosis, treatment planning must consider both the severity of liver disease and tumor burden. To minimize the impact to the patient while treating the tumor, techniques have been developed to target HCC. Anatomical targeting by surgical resection or locoregional therapies is generally reserved for patients with preserved liver function and minimal to moderate tumor burden. Patients with decompensated cirrhosis and small tumors are optimal candidates for liver transplantation, which offers the best chance of long-term survival. Yet, only 20%–30% of patients have disease amenable to anatomical targeting. For the majority of patients with advanced HCC, chemotherapy is used to target the tumor biology. Despite these treatment options, the five-year survival of patients in the United States with HCC is only 16%. In this review we provide a comprehensive overview of current approaches to target HCC. We also discuss emerging diagnostic and prognostic biomarkers, novel therapeutic targets identified by recent genomic profiling studies, and potential applications of immunotherapy in the treatment of HCC.

  13. Galectin-1-Induced Autophagy Facilitates Cisplatin Resistance of Hepatocellular Carcinoma.

    Yu-Chi Su

    Full Text Available Hepatocellular carcinoma (HCC is one of the most common cancers in Taiwan. Although chemotherapy is the primary treatment for HCC patients, drug resistance often leads to clinical failure. Galectin-1 is a beta-galactoside binding lectin which is up-regulated in HCC patients and promotes tumor growth by mediating cancer cell adhesion, migration and proliferation, but its role in chemoresistance of HCC is poorly understood. In this study we found that galectin-1 is able to lead to chemoresistance against cisplatin treatment, and subsequent inhibition has reversed the effect of cell death in HCC cells. Moreover, galectin-1 was found to induce autophagic flux in HCC cells. Inhibition of autophagy by inhibitors or knockdown of Atg5 cancels galectin-1-induced cisplatin resistance in HCC cells. Increase of mitophagy triggered by galectin-1 was found to reduce the mitochondrial potential loss and apoptosis induced by cisplatin treatment. Finally, using an in situ hepatoma mouse model, we clearly demonstrated that inhibition of galectin-1 by thiodigalactoside could significantly augment the anti-HCC effect of cisplatin. Taken together, our findings offer a new insight into the chemoresistance galectin-1 causes against cisplatin treatment, and points to a potential approach to improve the efficacy of cisplatin in the treatment of HCC patients.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies leading to high mortality rates in the general population; in cirrhotic patients, it is the primary cause of death. The diagnosis is usually delayed in spite of at-risk population screening recommendations, i.e., patients infected with hepatitis B or C virus. Hepatocarcinogenesis hinges on a great number of genetic and molecular abnormalities that lead to tumor angiogenesis and foster their dissemination potential. The diagnosis is mainly based on imaging studies such as computed tomography and magnetic resonance, in which lesions present a characteristic classical pattern of early arterial enhancement followed by contrast medium “washout” in late venous phase. On occasion, when imaging studies are not conclusive, biopsy of the lesion must be performed to establish the diagnosis. The Barcelona Clinic Liver Cancer staging method is the most frequently used worldwide and recommended by the international guidelines of HCC management. Currently available treatments include tumor resection, liver transplant, sorafenib and loco-regional therapies (alcoholization, radiofrequency ablation, chemoembolization). The prognosis of hepatocarcinoma is determined according to the lesion’s stage and in cirrhotic patients, on residual liver function. Curative treatments, such as liver transplant, are sought in patients diagnosed in early stages; patients in more advanced stages, were not greatly benefitted by chemotherapy in terms of survival until the advent of target molecules such as sorafenib.

    2018-01-01

    Background It has been reported that both of the miR-132/212 (micro-RNA) cluster members, miR-132 and miR-212, are downregulated in hepatocellular carcinoma. Nevertheless, the expression pattern and clinical utility of serum miR-132/212 in hepatocellular carcinoma are still unknown. Methods In this study, serum concentrations of miR-132 and miR-212 were measured in 80 hepatocellular carcinoma patients, 51 controls with chronic liver diseases and 42 healthy volunteers by using quantitative real-time polymerase chain reaction. Results In hepatocellular carcinoma patients, serum concentrations of miR-132 and miR-212 were significantly reduced and strongly correlated (r = 0.603, p hepatocellular carcinoma. Moreover, the combination of serum miR-132, miR-212 and alpha-fetoprotein improved the diagnostic efficiency for hepatocellular carcinoma, especially in sensitivity and negative predictive value. Serum miR-132 was associated with tumour differentiation degree ( p = 0.021) and tumour-node-metastasis stage ( p = 0.002); serum miR-212 correlated with tumour size ( p = 0.023) and tumour-node-metastasis stage ( p = 0.007). Kaplan-Meier analyses indicated poorer overall survival in hepatocellular carcinoma patients with lower serum concentrations of miR-132 ( p hepatocellular carcinoma.

    Linc-POU3F3 showed an up-regulated tendency and functioned as tumor promoter in glioma, esophageal cancer and colorectal cancer. There was no report about the expression pattern and clinical value of linc-POU3F3 in hepatocellular carcinoma. Thus, the purpose of our study is to explore the clinical significance and biological role of linc-POU3F3 in hepatocellular carcinoma. Our results suggested that levels of linc-POU3F3 were dramatically increased in hepatocellular carcinoma tissues and cell lines compared with paired normal hepatic tissues and normal hepatic cell line, respectively. Levels of linc-POU3F3 were positively correlated with clinical stage, tumor size, vascular invasion and metastasis. Moreover, high-expression of linc-POU3F3 was an independent prognostic factor for hepatocellular carcinoma patients. The gain- and loss-of-function experiments showed that linc-POU3F3 expression significantly promoted tumor cell proliferation, migration and invasion. In addition, linc-POU3F3 expression was negatively correlated with POU3F3 mRNA and protein expressions in hepatocellular carcinoma tissues, and negatively regulated POU3F3 mRNA and protein expressions in hepatocellular carcinoma cells. In conclusion, our study supports the first evidence that linc-POU3F3 plays an oncogenic role in hepatocellular carcinoma, and represents a potential therapeutic strategy for hepatocellular carcinoma patients.

    Full Text Available Alessandro Granito,1 Elena Guidetti,1 Laura Gramantieri2,3 1Dipartimento di Scienze Mediche e Chirurgiche Università di Bologna, Bologna, Italy; 2Dipartimento dell'Apparato Digerente, Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy; 3Centro di Ricerca Biomedica Applicata (CRBA, Azienda Ospedaliero-Universitaria Policlinico S Orsola-Malpighi e Università di Bologna, Bologna, Italy Abstract: c-MET is the membrane receptor for hepatocyte growth factor (HGF, also known as scatter factor or tumor cytotoxic factor, a mitogenic growth factor for hepatocytes. HGF is mainly produced by cells of mesenchymal origin and it mainly acts on neighboring epidermal and endothelial cells, regulating epithelial growth and morphogenesis. HGF/MET signaling has been identified among the drivers of tumorigenesis in human cancers. As such, c-MET is a recognized druggable target, and against it, targeted agents are currently under clinical investigation. c-MET overexpression is a common event in a wide range of human malignancies, including gastric, lung, breast, ovary, colon, kidney, thyroid, and liver carcinomas. Despite c-MET overexpression being reported by a large majority of studies, no evidence for a c-MET oncogenic addiction exists in hepatocellular carcinoma (HCC. In particular, c-MET amplification is a rare event, accounting for 4%–5% of cases while no mutation has been identified in c-MET oncogene in HCC. Thus, the selection of patient subgroups more likely to benefit from c-MET inhibition is challenging. Notwithstanding, c-MET overexpression was reported to be associated with increased metastatic potential and poor prognosis in patients with HCC, providing a rationale for its therapeutic inhibition. Here we summarize the role of activated HGF/MET signaling in HCC, its prognostic relevance, and the implications for therapeutic approaches in HCC.

    The global burden of hepatocellular carcinoma is increasing; actually, it is estimated as 750,000 new cases annually. This study was initiated to emphasize the possibility that gallic acid could alleviate hepatocarcinogenesis in vivo. In this study, 40 rats were enrolled and distributed as follows; group 1 was set as negative control, while all of groups 2, 3, and 4 were orally received N-nitrosodiethylamine for hepatocellular carcinoma induction. Group 2 was left untreated, whereas groups 3 and 4 were orally treated with gallic acid and doxorubicin, respectively. The current data indicated that gallic acid administration in hepatocellular carcinoma bearing rats yielded significant decline in serum levels of alpha-fetoprotein, glypican-3, and signal transducer and activator of transcription 3 along with significant enhancement in serum suppressors of cytokine signaling 3 level. Also, gallic acid-treated group displayed significant downregulation in the gene expression levels of hepatic gamma glutamyl transferase and heat shock protein gp96. Intriguingly, treatment with gallic acid remarkably ameliorated the destabilization of liver tissue architecture caused by N-nitrosodiethylamine intoxication as evidenced by histopathological investigation. In conclusion, this study demonstrates that the hepatocarcinogenic effect of N-nitrosodiethylamine can be abrogated by gallic acid supplementation owing to its affinity to regulate signal transducer and activator of transcription 3 signaling pathway through its outstanding bioactivities including antioxidant, anti-inflammatory, apoptotic, and antitumor effects.

    Using a 1.5 T MR imaging unit, T1- and T2-weighted images were obtained before and after i.v. administration of chondroitin sulfate iron colloid (CSIC) in order to differentiate hepatocellular carcinoma (n=20) from adenomatous hyperplasia without atypia (n=16). Differentiation was made from the tumor-liver contrast to noise ratio (CNR) and visual evaluation of the nodule, with reference to signal intensity relative to that of the surrounding liver. The CNR of adenomatous hyperplasia was on T1-weighted images significantly decreased after CSIC administration (p<0.01). On T2-weighted images, there was no significant difference in CNR after CSIC administration. On the other hand, the CNR of hepatocellular carcinoma was significantly increased after CSIC administration on both T1- and T2-weighted images (p<0.01). CSIC reflects intratumor reticuloendothelial cellular functions, and is therefore useful in differentiating hepatocellular carcinoma from adenomatous hyperplasia without atypia. (orig.).

    Mitochondrial dynamics of fission and fusion plays critical roles in a diverse range of important cellular functions, and its deregulation has been increasingly implicated in human diseases. Previous studies have shown that increased mitochondrial fission significantly promoted the proliferation of hepatocellular carcinoma (HCC) cells. However, how they influence the migration of tumour cells remained largely unknown. In the present study, we further investigated the effect of mitochondrial fission on the migration and metastasis of hepatocellular carcinoma cells. Moreover, the underlying molecular mechanisms and therapeutic application were explored. Our data showed that dynamin-1-like protein expression was strongly increased in distant metastasis of hepatocellular carcinoma when compared to primary hepatocellular carcinoma. In contrast, the mitochondrial fusion protein mitofusin 1 showed an opposite trend. Moreover, the expression of dynamin-1-like protein and mitofusin 1 was significantly associated with the disease-free survival of hepatocellular carcinoma patients. In addition, our data further showed that mitochondrial fission significantly promoted the reprogramming of focal-adhesion dynamics and lamellipodia formation in hepatocellular carcinoma cells mainly by activating typical Ca 2+ /CaMKII/ERK/FAK pathway. Importantly, treatment with mitochondrial division inhibitor-1 significantly decreased calcium signalling in hepatocellular carcinoma cells and had a potential treatment effect for hepatocellular carcinoma metastasis in vivo. Taken together, our findings demonstrate that mitochondrial fission plays a critical role in the regulation of hepatocellular carcinoma cell migration, which provides strong evidence for this process as a drug target in hepatocellular carcinoma metastasis treatment. © 2017 John Wiley & Sons A/S.

    Primary liver cancer is a significant cause of cancer-related death in both the United States and the world at large. Hepatocellular carcinoma comprises 90% of these primary liver cancers and has numerous known etiologies. Evaluation of these identified etiologies and other traditional risk factors cannot explain the high incidence rates of hepatocellular carcinoma in Texas. Texas is home to the second largest petrochemical industry and agricultural industry in the nation; industrial activity and exposure to pathogenic chemicals have never been assessed as potential links to the state's increased incidence rate of hepatocellular carcinoma. The association between the county-level concentrations of 4 air pollutants known to be linked to liver cancer, vinyl chloride, arsenic, benzene, and 1,3-butadiene, and hepatocellular carcinoma rates was evaluated using nonparametric generalized additive logistic regression and gamma regression models. Hepatocellular carcinoma incidence rates for 2000-2013 were evaluated in comparison to 1996 and 1999 pollution concentrations and hepatocellular carcinoma rates for the subset of 2006-2013 were evaluated in comparison to 2002 and 2005 pollution concentrations, respectively. The analysis indicates that the relationship between the incidence of liver cancer and air pollution and risk factors is nonlinear. There is a consistent significant positive association between the incidence of liver cancer and hepatitis C prevalence rates (gamma all years, p < 0.05) and vinyl chloride concentrations (logistic 2002 and 2005, p < 0.0001; gamma 2002 and 2005, p < 0.05). This study suggests that vinyl chloride is a significant contributor to the incidence of liver cancer in Texas. The relationship is notably nonlinear. Further, the study supports the association between incidence of liver cancer and prevalence of hepatitis B.

    Objective: To label rat bone marrow mesenchymal stem cells with superparamagnetic iron oxide (SPIO) and to explore the tropism of BMSCs for hepatocellular carcinoma cells after transplantation in vivo. Methods: BMSCs from bone marrow of Sprague-Dawly (SD) rats were cultured isolated and purified. Labeled BMSCs was achieved using Feridex. Twenty-four hepatocellular carcinoma models of SD rats were induced two weeks before transplantation. The models were divided into three groups in random: the labeled BMSCs and unlabeled BMSCs were transplanted respectively into the rat's livers of experimental group (n=12) and control group A (n=6) via spleens, and no transplant was done for control group B (n=6). MR imaging was performed to monitor the transplanted cells after 1,3,7,14 d using 1.5 T MR system. Signal intensity ratio (SI/SI * ) between tumor and hepatic tissue on T 2 * WI were measured and compared by one-factor analysis of variance. After MR imaging, Prussian blue staining was performed. MR imaging findings were compared with histological sections. Results: Prussian blue staining confirmed the labeling efficiency of BMSCs was above 90%. SI/SI * of experimental group before and 1, 3, 7, 14 d after transplantation were 3.18±0.21, 1.98±0.20, 2.38±0.28, 2.70±0.25 and 3.16±0.24 respectively. Following transplantation of BMSCs, signal intensity decrease was found in hepatocellular carcinoma of experimental group (F=56.65, P 2 * WI (P>0.05). A large number of Prussian blue staining positive cells were found in hepatocellular carcinoma in experimental group. Histological section with Prussian blue staining had a good correlation with the signal intensity changes on MR images at different time. Conclusion: BMSCs display significant tropism to hepatocellular carcinoma and may be an ideal gene therapy vehicle against hepatocellular carcinoma. (authors)

    Gene regulation of many key cell-cycle players in S-, G(2) phase, and mitosis results from transcriptional repression in their respective promoter regions during the G(0) and G(1) phases of cell cycle. Within these promoter regions are phylogenetically conserved sequences known as the cell-cycle-dependent element (CDE) and cell-cycle genes homology regions (CHR) sites. Thus, we hypothesize that transcriptional regulation of cell-cycle regulation via the CDE/CHR region together with liver-specific apolipoprotein E (apoE)-hAAT promoter could bring about a selective transgene expression in proliferating human hepatocellular carcinoma. We show that the newly generated vector AH-6CC-L2C could mediate hepatocyte-targeted luciferase gene expression in tumor cells and freshly isolated short-term hepatocellular carcinoma cultures from patient biopsy. In contrast, normal murine and human hepatocytes infected with AH-6CC-L2C expressed minimal or low luciferase activities. In the presence of prodrug 5-fluorocytosine (5-FC), AH-6CC-L2C effectively suppressed the growth of orthotopic hepatocellular carcinoma patient-derived xenograft mouse model via the expression of yeast cytosine deaminase (yCD) that converts 5-FC to anticancer metabolite 5-fluoruracil. More importantly, we show that combination treatment of AH-6CC-L2C with an EZH2 inhibitor, DZNep, that targets EpCAM-positive hepatocellular carcinoma, can bring about a greater therapeutic efficacy compared with a single treatment of virus or inhibitor. Our study showed that targeting proliferating human hepatocellular carcinoma cells through the transcriptional control of therapeutic gene could represent a feasible approach against hepatocellular carcinoma.

    In Japan, most cases of hepatocellular carcinoma (HCC) are related to chronic hepatitis C (HCV) or B (HBV) virus infections. Increased liver cancer risk among atomic-bomb survivors has been reported based on mortality studies or tumor registries, but virus infection status-particularly B, which is associated with radiation dose-was not taken account. The objectives of this study were to determine HCC risk in relation to radiation exposure, after adjusting for virus infection in a cohort follow-up study. The study subjects were 6,121 Adult Health Study participants who received tests for hepatitis C and B virus antigen or antibody in 1993-5. A total of 58 HCC cases were newly diagnosed during 1993-2002. As of August 2002, 8% of individuals positive for HCV antibody subsequently developed HCC, compared with less than 1% of individuals who were negative for HCV antibody. Cox regression analysis revealed that the incidence of HCC was 27 times higher among HCV antibody positive individuals and 7 times higher among HBV surface antigen positive individuals. Men had 1.6 times higher risk than women. The risk of HCC increased with age at exam overall but declined with age at exam among the HCV-infected persons. Risk of HCC was 1.3 times higher on average among individuals exposed to radiation, but persons who were younger at the time of bombing had a higher risk of HCC for radiation. There was no evidence of interaction between HCV and radiation exposure. In conclusion, hepatocellular carcinoma risk increased with radiation exposure among persons exposed at young ages, even after adjusting for hepatitis virus infection. There was no evidence of synergy between radiation and HCV infection in this late follow-up. Further study including earlier diagnosed cases is needed to clarify this issue

    {sup 99m}Tc-Sulfur Colloid is concentrated in Kupffer cells of the liver, whereas the new biliary agents such as {sup 99m}Tc-HIDA are processed by hepatic parenchymal cells. The distant metastatic lesions in skull and lung of the primary hepatocellular carcinoma in 38-year old Korean male were detected with {sup 99m}Tc-HIDA scintigraphy. The chest PA, skull bone X-ray and radionuclide scintigraphic studies are illustrated. This observation suggests that {sup 99m}Tc-HIDA scintigraphy is useful for detection of distant metastases of primary hepatocellular carcinoma.

    1982-12-01

    Serum Alkaline Phosphatase (ALP) was studied in relation to liver scintigrams of 54 patients with hepatocellular carcinoma. The ALP activity was higher with larger tumors and in multiple tumors. Within the single tumor group, the activity was higher when the tumor was located in the hilum than in the periphery. The incidence of ALP-1 isoenzyme (bile ALP) roughly paralleled the total ALP activity. These results suggest that the variation of serum ALP seen in each individual patients with hepatocellular carcinoma reflects the volume of cholestatic liver tissue, which is changed by the number, size and localization of the tumor nodules in the liver.

    2014-03-01

    Full Text Available Many investigations have revealed that a low recurrence rate of hepatocellular carcinoma (HCC is associated with high serum albumin levels in patients; therefore, high levels of serum albumin are a major indicator of a favorable prognosis. However, the mechanism inhibiting the proliferation of HCC has not yet been elucidated, so we investigated the effect of serum albumin on HCC cell proliferation. Hep3B was cultured in MEM with no serum or containing 5 g/dL human albumin. As control samples, Prionex was added to generate the same osmotic pressure as albumin. After 24-h incubation, the expressions of α-fetoprotein (AFP, p53, p21, and p57 were evaluated with real-time PCR using total RNA extracted from the liver. Protein expressions and the phosphorylation of Rb (retinoblastoma were determined by Western blot analysis using total protein extracted from the liver. For flow cytometric analysis of the cell cycle, FACS analysis was performed. The percentages of cell cycle distribution were evaluated by PI staining, and all samples were analyzed employing FACScalibur (BD with appropriate software (ModFit LT; BD. The cell proliferation assay was performed by counting cells with using a Scepter handy automated cell counter (Millipore. The mRNA levels of AFP relative to Alb(−: Alb(−, Alb(+, and Prionex, were 1, 0.7 ± 0.2 (p < 0.001 for Alb(−, and 1 ± 0.3, respectively. The mRNA levels of p21 were 1, 1.58 ± 0.4 (p = 0.007 for Alb(− and p = 0.004 for Prionex, and 0.8 ± 0.2, respectively. The mRNA levels of p57 were 1, 4.4 ± 1.4 (p = 0.002 for Alb(− and Prionex, and 1.0 ± 0.1, respectively. The protein expression levels of Rb were similar in all culture media. The phosphorylation of P807/811 and P780 of Rb protein was reduced in Alb(+. More cells in the G0/G1 phase and fewer cells in S and G2/M phases were obtained in Alb(+ than in Alb(− (G0/G1: 60.9%, 67.7%, 61.5%; G2/M: 16.5%, 13.1%, 15.6%; S: 22.6%, 19.2%, 23.0%, Alb(−, Alb

  8. Relationship between hepatocellular carcinoma, metabolic syndrome and non-alcoholic fatty liver disease: which clinical arguments?

    Rosmorduc, Olivier

    2013-05-01

    Obesity and the metabolic syndrome are growing epidemics associated with an increased risk for many types of cancer. In the liver, inflammatory and angiogenic changes due to insulin resistance and fatty liver disease are associated with an increased incidence of liver cancer. Regardless of underlying liver disease, cirrhosis remains the most important risk factor for hepatocellular carcinoma (HCC) although are cases of HCC arising without cirrhosis raise the possibility of a direct carcinogenesis secondary to Non-alcoholic Fatty Liver Disease (NAFLD). Moreover, metabolic syndrome and its different features may also increase the risk of HCC in the setting of chronic liver diseases of other causes such as viral hepatitis or alcohol abuse. Taking into account all these data, it is necessary to better determine the risk of developing HCC in patients with metabolic syndrome to improve the screening guidelines and develop prophylactic treatments in this setting.

    2018-02-01

    Liver cancer is the second leading cause of cancer-related death worldwide.1 Hepatocellular carcinoma (HCC) is the most common primary liver cancer accounting for approximately 80% of cases. Intrahepatic cholangiocarcinoma (ICC) is a rare liver cancer, arising in patients with the same risk factors as HCC, but treatment options and prognosis differ. The diagnosis of HCC is based primarily on imaging but distinguishing between HCC and ICC is challenging due to common radiographic features.2-4 The aim of the present study is to classify HCC and ICC in portal venous phase CT. 107 patients with resected ICC and 116 patients with resected HCC were included in our analysis. We developed a deep neural network by modifying a pre-trained Inception network by retraining the final layers. The proposed method achieved the best accuracy and area under the receiver operating characteristics curve of 69.70% and 0.72, respectively on the test data.

    1983-04-01

    It is well-known that patients with chronic hepatitis and liver cirrhosis are frequently accompanied by hepatocellular carcinoma (hepatoma). They are called high risk group for hepatoma. In order to detect a small hepatoma, it is reasonable for us to perform screening examinations on these high risk group patients. Optimal screening interval, however, has not been established. In this report, a theoretical analysis was made to estimate optimal screening interval by imaging procedure such as ultrasonography, x-ray computed tomography and scintigraphy. By the analysis of eight cases, mean doubling time of hepatoma was estimated about four months (73 - 143 days). If we want to detect a hepatoma not greater than 3.0cm in diameter, medical screening procedure combining ultrasonography and scintigraphy should be performed once per about nine months.

  11. Late solitary pelvic metastasis of hepatocellular carcinoma mimicking alpha-fetoprotein-producing gynaecologic tumour

    Ji He Kim

    2018-01-01

    Full Text Available Extrahepatic spread of hepatocellular carcinoma (HCC is uncommon; and, pelvic metastasis, in particular, is extremely rare. A 71-year-old woman was admitted for evaluation of pelvic solitary solid mass. She had undergone a left lobectomy 28 years previously. Magnetic resonance imaging of the abdomen and pelvis demonstrated a heterogeneous mass in the right pelvic cavity, whereas no space-occupying lesions or ascites were detected in the liver. CA 125 levels were within normal limits; however, serum alpha-fetoprotein levels were markedly elevated. She underwent laparoscopic pelvic mass excision, total hysterectomy, and bilateral salpingo-oophorectomy. Histopathologic findings and immunochemical staining results indicated metastatic HCC. Herein, we report an unusual case of a patient with solitary recurrence in the pelvic cavity 28 years after initial diagnosis and treatment.

    2006-11-07

    We describe a rare case of HCV-related recurrent multiple hepatocellular carcinoma (HCC) metastasizing to the skull base involving multiple cranial nerves in a 50-year-old woman. The patient presented with symptoms of ptosis, fixation of the right eyeball, and left abducens palsy, indicating disturbances of the right oculomotor and trochlear nerves and bilateral abducens nerves. Brain contrast-enhanced computed tomography (CT) revealed an ill-defined mass with abnormal enhancement around the sella turcica. Brain magnetic resonance imaging (MRI) disclosed that the mass involved the clivus, cavernous sinus, and petrous apex. On contrast-enhanced MRI with gadolinium-chelated contrast medium, the mass showed inhomogeneous intermediate enhancement. The diagnosis of metastatic HCC to the skull base was made on the basis of neurological findings and imaging studies including CT and MRI, without histological examinations. Further studies may provide insights into various methods for diagnosing HCC metastasizing to the craniospinal area.

    2014-01-01

    To determine the clinical significance of silent mating type information regulation 2 homolog 1 (SIRT1) expression in Hepatocellular Carcinoma (HCC) and its association with P53 and Yes-associated protein 2 (YAP2) expression. Study Design: Observational study. Place and Duration of Study: Department of General Surgery, China-Japan Union Hospital of Jilin University, Changchun, China, from January 2000 to January 2010. Methodology: Tissue microarray technique and immunohistochemistry were conducted to detect the expression of SIRT1, P53 and YAP2 proteins in 300 self-paired HCC samples. Associations with clinicopathologic manifestations were analyzed, overall survival analysis and multivariate analysis were performed. Results: By tissue microarray technique and immunohistochemistry on 300 self-paired HCC samples, it was found that SIRT1, P53 and YAP2 were significantly overexpressed in HCC tumor tissues compared with adjacent non-tumor tissues. SIRT1 immunostaining localized both in the nucleus (145/300, 48.3%) and the cytoplasm (70/300, 23.3%), and the overexpression of nuclear SIRT1 was positively related to the overexpression of P53 and YAP2. Survival analysis showed that nuclear SIRT1, P53 and YAP2 overexpression predicted poor overall survival while cytoplasmic SIRT1 overexpression predicted longer overall survival. Multivariate analysis showed nuclear SIRT1 and P53 overexpression as independent tumor promoters while cytoplasmic SIRT1 overexpression as an independent tumor suppressor. Conclusion: SIRT1 was overexpressed in HCC and the expression was positively related to P53 and YAP2 expression. As the nuclear SIRT1 functions as a tumor promoter and cytoplasmic SIRT1 functions as a tumor suppressor, the role of SIRT1 in HCC should be reconsidered. (author)

    AIM: To assess the rate and risk factors for tumour seeding in a large cohort of patients. METHODS: Over an 8-year period, 1436 hepatocellular carcinoma (HCC) patients with 2423 tumour nodules underwent 3015 image-guided percutaneous cryoablation sessions [1215 guided by ultrasonography and 221 by spiral computed tomography (CT)]. Follow-up CT or magnetic resonance imaging was performed every 3 mo. The detailed clinical data were recorded to analyse the risk factors for seeding. RESULTS: The median follow-up time was 18 (range 1-90) mo. Seeding was detected in 11 patients (0.76%) at 1-24 (median 6.0) mo after cryoablation. Seeding occurred along the needle tract in 10 patients and at a distant location in 1 patient. Seeded tumours usually showed similar imaging and histopathological features to the primary HCCs. Univariate analyses identified subcapsular tumour location and direct subcapsular needle insertion as risk factors for seeding. Multivariate analysis showed that only direct subcapsular needle insertion was an independent risk factor for seeding (P = 0.017; odds ratio 2.57; 95%CI: 1.47-3.65). Seeding after cryoablation occurred earlier in patients with poorly differentiated HCC than those with well or moderately differentiated HCC [1.33 ± 0.577 mo vs 11.12 ± 6.896 mo; P = 0.042; 95%CI: (-19.115)-(-0.468)]. CONCLUSION: The risk of seeding after cryoablation for HCC is small. Direct puncture of subcapsular tumours should be avoided to minimise seeding. PMID:23236233

  16. Current management of hepatocellular carcinoma: An Eastern perspective

    Yim, Hyung Joon; Suh, Sang Jun; Um, Soon Ho

    2015-01-01

    Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death, especially in Eastern areas. With advancements in diagnosis and treatment modalities for HCC, the survival and prognosis of HCC patients are improving. However, treatment patterns are not uniform between areas despite efforts to promote a common protocol. Although many hepatologists in Asian countries may adopt the principles of the Barcelona Clinic Liver Cancer staging system, they are also independently making an effort to expand the indications of each treatment and to combine therapies for better outcomes. Several expanded criteria for liver transplantation in HCC have been developed in Asian countries. Living donor liver transplantation is much more commonly performed in these countries than deceased donor liver transplantation, and it may be preceded by other treatments such as the down-staging of tumors. Local ablation therapies are often combined with transarterial chemoembolization (TACE) and the outcome is comparable to that of surgical resection. The indications of TACE are expanding, and there are new types of transarterial therapies. Although data on drug-eluting beads, TACE, and radioembolization in Asian countries are still relatively sparse compared with Western countries, these methods are gradually gaining popularity because of better tolerability and the possibility of improved response rates. Hepatic arterial infusion chemotherapy and radiotherapy are not included in Western guidelines, but are currently being used actively in several Asian countries. For more advanced HCCs, appropriate combinations of TACE, radiotherapy, and sorafenib can be considered, and emerging data indicate improved outcomes of combination therapies compared with single therapies. To include these paradigm shifts into newer treatment guidelines, more studies may be needed, but they are certainly in progress. PMID:25852267

    To evaluate patterns of recurrence and factors which influence them in radiofreqency (RF) ablation for the treatment of hepatocellular carcinoma (HCC). Between May 1999 and March 2000, 69 patients with 82 HCCs underwent RF ablation for complete necrosis. They were diagnosed by tissue biopsy or tumor marker, and the results of triphasic spiral CT. The indications were that nodular lesions were clearly visualized at sonography, less than 5 cm in size and less than four in number, and that patients had no history of previous treatment. Local therapeutic efficacy such as complete necrosis and marginal recurrence, and new lesions were evaluated by means of triphasic spiral CT performed at least six months after the completion of ablation. We then analyzed the correlation between local therapeutic efficacy and various influential factors such as tumor size, whether the tumor was attached to the portal vein, gross morphology, Child-Pugh classification, and {alpha}-fetoprotein level vefore the procedure, as well as the correlation between new lesions and influential factors which included the {alpha}-fetoprotein level before the procedure, Child-Pugh classification, and multiplicity per person. During a mean follow-up period of 8.95 (range, 6-14) months after RF ablation, the rate of complete necrosis and of marginal recurrence was 91% and 12%, respectively. When a tumor was larger and was attached to a large branch of the portal vien, the incidence of incomplete necrosis and marginal recurrence was greater. The occurrence rate of new lesion was 19.4%. When the {alpha}-fetoprotein level before the procedure was higher and a tumor was multiple in number, new lesions occurred more frequently. Sufficient knowledge of patterns of recurrence and the factors which influence them might improve the therapeutic effects of RF ablation in patients with HCC.

    Full Text Available Hepatocellular carcinoma (HCC is the third leading cause of cancer deaths worldwide. Effective treatment of HCC patients is hampered by the lack of sensitive and specific diagnostic markers of HCC. Alpha-fetoprotein (AFP, the currently used HCC marker, misses 30%–50% of HCC patients, who therefore remain undiagnosed and untreated. In order to identify novel diagnostic markers that can be used individually or in combination with AFP, we used an antibody array platform to detect the levels of candidate proteins in the plasma of HCC patients (n = 48 and patients with chronic hepatitis B or C viral infections (n = 19 (both of which are the major risk factors of HCC. We identified 7 proteins that significantly differentiate HCC patients from hepatitis patients (p < 0.05 (AFP, CTNNB, CSF1, SELL, IGFBP6, IL6R, and VCAM1.Importantly, we also identified 8 proteins that significantly differentiate HCC patients with ‘normal’ levels of AFP (<20 ng/ml from hepatitis patients (p < 0.05 (IL1RN, IFNG, CDKN1A, RETN, CXCL14, CTNNB, FGF2, and SELL. These markers are potentially important complementary markers to AFP. Using an independent immunoassay method in an independent group of 23 HCC patients and 22 hepatitis patients, we validated that plasma levels of CTNNB were significantly higher in the HCC group (p = 0.020. In conclusion, we used an antibody array platform to identify potential circulating diagnostic markers of HCC, some of which may be valuable when used in combination with AFP. The clinical utility of these newly identified HCC diagnostic markers needs to be systematically evaluated.

    2006-09-01

    The survival of patients with unresectable advanced hepatocellular carcinoma (HCC) with portal vein thrombosis is dismal. Current therapeutic options have limited efficacy. Vitamin K has been shown to have antitumor effect on HCC cells both in cell lines and patients with advanced HCC. The aim of this study was to assess the clinical efficacy of high dose vitamin K3 in the treatment of advanced HCC with portal vein thrombosis. Forty-two consecutive patients with advanced HCC (Stage C according to BCLC staging system) with portal vein thrombosis were randomized into two groups: (i) high dose vitamin K3 (n = 23); and (ii) placebo (n = 19). The vitamin K3 was administered by i.v. infusion of 50 mg/day with daily increase of dose by 50 mg for 6 days, followed by 20 mg i.m. twice daily for 2 weeks. Of the 23 patients treated with vitamin K, one (4.3%) achieved complete response and three (13%) partial response, for a total of four (17.4%) objective responders overall. The overall mean survival was 8.9 +/- 8.8 months (median: 6; range 1-37 months) in the vitamin K group and 6.8 +/- 5.3 months (median: 5; range 1.5-21 months) in the placebo group (P = 0.552). The mean duration of survival was longer in patients in the vitamin K group who achieved objective response (22.5 +/- 12.2; median: 21; range 11-37 months) as compared to patients not achieving objective response (6.1 +/- 4.6; median: 5; range 1-16 months) (P = 0.0.002). Portal vein thrombosis resolved with complete patency in one (4.35%) patient. Treatment with high dose vitamin K produces objective response in 17% patients with improved survival in patients achieving objective response; however, it does not affect the overall survival.

    The frequency with which patients in Child-Pugh B having hepatocellular carcinoma are treated following the international guidelines according to the Barcelona Clinic Liver Cancer stages is unknown. To investigate treatment allocation for Child-Pugh B patients in different tumour stages, with particular interest in the intermediate stage. Patients were retrospectively identified from a consecutively collected series. Treatment was carried out primarily according to the guidelines. Of 86 Child-Pugh B patients, 45 were Barcelona early stage, of which the Child-Pugh scores were 46.7% B7, 33.3% B8, 20.0% B9; 27 patients were intermediate stage (B7 59.3%, B8 37.0% and B9 3.7% respectively), 12 were advanced (41.7% B7, 25.0% B8 and 33.3% B9) and 2 were terminal (both B9). In the intermediate stage, transarterial chemoembolization (or ablation) was performed in 68.8% of the Child-Pugh B7 patients, 50% of the B8 patients and 0% of the B9 patients. Median survival of the intermediate patients was 8.0 months (9.0 in B7 vs. 6.0 in -B8/B9, P=0.048). Survival of the intermediate stage patients undergoing chemoembolisation was 22.0 months in Child-Pugh B7 and 6.0 in B8. Approximately half of the intermediate stage patients can undergo locoregional treatment with good survival when in the Child-Pugh B7. The Child-Pugh numeric score impacts survival, suggesting that this tumour stage be refined. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

In this regard, tumor size is one of the two main prognostic factors for surgical resection, which constitutes the only curative treatment for HCC along with liver transplantation. However, techniques for HCC surveillance and diagnosis that are currently used in clinical practice have certain limitations that may be inherent to the tumor development. Thus, it is important to continue efforts in the search for biomarkers that increase diagnostic accuracy for HCC. In this review, we focus on different biological sources of candidate biomarkers for HCC diagnosis. Although those biomarkers identified from biological samples obtained by noninvasive methods have greater diagnostic value, we have also considered those obtained from liver tissue because of their potential therapeutic value. To date, sorafenib is the only US Food and Drug Administration-approved antineoplastic for HCC. However, this therapeutic agent shows very low tumor response rates and frequently causes acquired resistance in HCC patients. We discuss the use of HCC biomarkers as therapeutic targets themselves, or as targets to increase sensitivity to sorafenib treatment. Keywords: diagnosis, sorafenib, therapy

    The glycoprotein CD147 has a role in tumor progression, is readily detectable in the circulation, and is abundantly expressed in hepatocellular carcinoma (HCC). Advanced HCC patients are a heterogeneous group with some individuals having dismal survival. The aim of this study was to examine circulating soluble CD147 levels as a prognostic marker in HCC patients. CD147 was measured in 277 patients (110 HCC, 115 chronic liver disease, and 52 non-liver disease). Clinical data included etiology, tumor progression, Barcelona Clinic Liver Cancer (BCLC) stage, and treatment response. Patients with HCC were stratified into two groups based upon the 75th percentile of CD147 levels (24 ng/mL). CD147 in HCC correlated inversely with poor survival (P = 0.031). Increased CD147 predicted poor survival in BCLC stages C and D (P = 0.045), and CD147 levels >24 ng/mL predicted a significantly diminished 90-day and 180-day survival time (hazard ratio [HR] = 6.1; 95% confidence interval [CI]: 2.1-63.2; P = 0.0045 and HR = 2.8; 95% CI: 1.2-12.6; P = 0.028, respectively). In BCLC stage C, CD147 predicted prognosis; levels >24 ng/mL were associated with a median survival of 1.5 months compared with 6.5 months with CD147 levels ≤24 ng/mL (P = 0.03). CD147 also identified patients with a poor prognosis independent from treatment frequency, modality, and tumor size. Circulating CD147 is an independent marker of survival in advanced HCC. CD147 requires further evaluation as a potential new prognostic measure in HCC to identify patients with advanced disease who have a poor prognosis. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    2010-10-01

    Full Text Available Abstract Background Hepatocellular carcinoma (HCC still is a big burden for China. In recent years, the third-generation platinum compounds have been proposed as potential active agents for HCC. However, more experimental and clinical data are warranted to support the proposal. In the present study, the effect of lobaplatin was assessed in five HCC cell lines and the underlying molecular mechanisms in terms of cell cycle kinetics were explored. Methods Cytotoxicity of lobaplatin to human HCC cell lines was examined using MTT cell proliferation assay. Cell cycle distribution was determined by flow cytometry. Expression of cell cycle-regulated genes was examined at both the mRNA (RT-PCR and protein (Western blot levels. The phosphorylation status of cyclin-dependent kinases (CDKs and retinoblastoma (Rb protein was also examined using Western blot analysis. Results Lobaplatin inhibited proliferation of human HCC cells in a dose-dependent manner. For the most sensitive SMMC-7721 cells, lobaplatin arrested cell cycle progression in G1 and G2/M phases time-dependently which might be associated with the down-regulation of cyclin B, CDK1, CDC25C, phosphorylated CDK1 (pCDK1, pCDK4, Rb, E2F, and pRb, and the up-regulation of p53, p21, and p27. Conclusion Cytotoxicity of lobaplatin in human HCC cells might be due to its ability to arrest cell cycle progression which would contribute to the potential use of lobaplatin for the management of HCC.

  4. Hepatocellular Carcinoma Surveillance Among Cirrhotic Patients With Commercial Health Insurance.

    Goldberg, David S; Valderrama, Adriana; Kamalakar, Rajesh; Sansgiry, Sujit S; Babajanyan, Svetlana; Lewis, James D

    2016-03-01

    To evaluate hepatocellular carcinoma (HCC) surveillance rates among commercially insured patients, and evaluate factors associated with compliance with surveillance recommendations. Most HCC occurs in patients with cirrhosis. American Association for the Study of Liver Diseases and European Association for the Study of the Liver guidelines each recommend biannual HCC surveillance for cirrhotic patients to diagnose HCC at an early, curable stage. However, compliance with these guidelines in commercially insured patients is unknown. We used the Truven Health Analytics databases from 2006 to 2010, using January 1, 2006 as the anchor date for evaluating outcomes. The primary outcome was continuous surveillance measure, defined as the proportion of time "up-to-date" with surveillance (PTUDS), with the 6-month interval immediately following each ultrasound categorized as "up-to-date." During a median follow-up of 22.9 (interquartile range, 16.3 to 33.9) months among 8916 cirrhotic patients, the mean PTUDS was 0.34 (SD, 0.29), and the median was 0.31 (interquartile range, 0.03 to 0.52). These values increased only modestly with inclusion of serum alpha-fetoprotein testing, contrast-enhanced abdominal computed tomographic scans or magnetic resonance imagings, and/or extension of up-to-date time to 12 months. Being diagnosed by a nongastroenterology provider and increasing age were significantly associated with decreased HCC surveillance (Psurveillance (Psurveillance rates remained low. HCC surveillance rates in commercially insured at-risk patients remain poor despite formalized guidelines, highlighting the need to develop interventions to improve surveillance rates.

  5. Local Arterial Therapies in the Management of Unresectable Hepatocellular Carcinoma.

    2017-10-27

    Most patients with hepatocellular carcinoma present with intermediate to advanced disease, where curative therapies are no longer an option. These patients with intermediate to advanced disease represent a heterogeneous population with regard to tumor burden, liver function, and performance status. While the Barcelona Clinic Liver Cancer (BCLC) staging system offers guidelines for the management of these patients, strict adherence to these guidelines may limit treatment options for these patients. Several locoregional therapies exist for these patients, including conventional transarterial chemoembolization (cTACE), transarterial embolization (TAE), drug-eluting embolization (DEE), and radioembolization. Evidence is also emerging for the role of radiation therapy including most notably stereotactic body radiation therapy and proton therapy, although at the current time, clinical trial participation is encouraged. While cTACE is traditionally recommended for BCLC B disease, both cTACE and radioembolization are increasingly used for patients with intermediate disease, as well as in select patients with BCLC A and C disease. TAE and DEE are limited in their use currently, due to lack of clear survival benefits or clinical advantages over cTACE. While several studies have demonstrated similar OS between cTACE and radioembolization, radioembolization provides a longer time to progression and fewer toxicities compared to cTACE. This is particularly relevant in the setting of advanced BCLC B and early BCLC C disease, where patients may have limited reserve. Radioembolization also has additional roles as an alternative to ablation, inducing liver hypertrophy, treating patients with PVT, and downstaging lesions to transplant. Ongoing studies will further define the role of locoregional treatment potentially in combination with and in light of developments in systemic therapy.

  6. A systems biology-based classifier for hepatocellular carcinoma diagnosis.

    Yanqiong Zhang

    Full Text Available AIM: The diagnosis of hepatocellular carcinoma (HCC in the early stage is crucial to the application of curative treatments which are the only hope for increasing the life expectancy of patients. Recently, several large-scale studies have shed light on this problem through analysis of gene expression profiles to identify markers correlated with HCC progression. However, those marker sets shared few genes in common and were poorly validated using independent data. Therefore, we developed a systems biology based classifier by combining the differential gene expression with topological features of human protein interaction networks to enhance the ability of HCC diagnosis. METHODS AND RESULTS: In the Oncomine platform, genes differentially expressed in HCC tissues relative to their corresponding normal tissues were filtered by a corrected Q value cut-off and Concept filters. The identified genes that are common to different microarray datasets were chosen as the candidate markers. Then, their networks were analyzed by GeneGO Meta-Core software and the hub genes were chosen. After that, an HCC diagnostic classifier was constructed by Partial Least Squares modeling based on the microarray gene expression data of the hub genes. Validations of diagnostic performance showed that this classifier had high predictive accuracy (85.88∼92.71% and area under ROC curve (approximating 1.0, and that the network topological features integrated into this classifier contribute greatly to improving the predictive performance. Furthermore, it has been demonstrated that this modeling strategy is not only applicable to HCC, but also to other cancers. CONCLUSION: Our analysis suggests that the systems biology-based classifier that combines the differential gene expression and topological features of human protein interaction network may enhance the diagnostic performance of HCC classifier.

    We report our institutional observations of ten patients with advanced hepatocellular carcinoma (HCC) (seven and three were Child-Pugh class A and B, respectively) who received compassionate regorafenib therapy between June 2016 and January 2017. These patients did not fit the rigid criteria of a clinical trial and represented the use of regorafenib in an everyday clinic situation. Regorafenib (160 mg P.O. daily) was administered to patients on a 4-week cycle (3 weeks on, 1 week off) until disease progression (assessed using mRECIST criteria) or discontinuation secondary to toxicity (assessed using CTCAE criteria). Relevant clinical data were abstracted from patient medical records and reviewed retrospectively. The median duration of patient treatment was 6.6 weeks, and the median time to disease progression was 12.5 weeks. Most common treatment emergent adverse events were fatigue, diarrhea, and hand-foot skin reaction. Elevated AST and ALT were the most commonly observed laboratory-assessed adverse events, which reached grade 3 status in the Child-Pugh class B patients only. We observed intolerance to regorafenib treatment in one patient who had previously received a liver transplant. We also saw lithium toxicity in one patient receiving long-term lithium treatment, suggesting a potential and unexpected drug-drug interaction with regorafenib. Taken together, our observations indicate that regorafenib is beneficial in the treatment of patients with advanced HCC who progressed on or demonstrated intolerance to sorafenib therapy; however, careful selection and close monitoring of patients is necessary to maximize the benefit while minimizing the toxicities of regorafenib treatment.

    Here, we aim to investigate the molecular mechanism of regorafenib and verify the potential druggable target for the treatment of hepatocellular carcinoma (HCC). HCC cell lines (PLC5, HepG2, Hep3B, SK-Hep1, and HA59T) were used to investigate the in vitro effect of regorafenib. Phosphatase activity was analyzed in HCC cells and purified SHP-1 proteins. PLC5-bearing mice were used to test the therapeutic efficiency of 20 and 40 mg/kg/d treatment with regorafenib ([Formula: see text] mice). The clinical relevance of STAT3 signaling was investigated with 142 tumor samples from different patients with HCC. Descriptive statistical analysis was used to compare the baseline characteristics of patients and the expression of p-STAT3. Regorafenib inhibited STAT3-related signaling in a dose-dependent manner and was a more potent inhibitor of STAT3 than sorafenib. Regorafenib increased SHP-1 phosphatase activity in purified SHP-1 protein directly. N-SH2 domain deletion and D61A mutants mimicking open-form SHP-1 partially abolished regorafenib-induced STAT3 inhibition and apoptosis. Importantly, a higher level of expression of STAT3 was found in patients with advanced clinical stages (P = 0.009) and poorly differentiated tumors (P = 0.035). Regorafenib induced significant tumor inhibition by relieving the autoinhibited N-SH2 domain of SHP-1 directly and inhibiting p-STAT3 signals. STAT3 may be suitable as a prognostic marker of HCC development, and may be a druggable target for HCC-targeted therapy using regorafenib. ©2014 American Association for Cancer Research.

    2005-01-01

    Purpose: To evaluate the response to local radiotherapy (RT) for unresectable hepatocellular carcinoma (HCC) and to analyze the dose-response relationship and the treatment-related morbidities. Methods and materials: Between 1998 and 2002, 59 patients who were treated with localized RT were evaluated. RT was delivered with a curative intent, and the radiation dose was 30-55 Gy (biologic effective dose of 39.0-70.2 Gy 10 using the α/β ratio of 10 Gy) with 2-3 Gy as a daily dose. The tumor response was evaluated by the change in maximum tumor size on serial CT scans, and the morbidity was evaluated by the Common Terminology Criteria for Adverse Events v3.0. Results: An objective tumor response was achieved in 39 of 59 patients (66.1%) with complete response (CR) in 5 patients and partial response (PR) in 34 patients. More than 50 Gy 10 had a significant response; CR or PR was 72.8% with >50 Gy 10 and 46.7% with ≤50 Gy 10 (p = 0.0299). The 2-year overall survival rate after RT was 27.4% (median survival time: 10 months), and this was affected by the tumor response (p = 0.0640); the 2-year overall survival rate after RT was 50.0% for CR and 21.8% for PR. There was no Grade 3 or 4 acute toxicity, and 3 patients (5.1%) developed gastric or duodenal ulcer. Conclusions: Radiotherapy for unresectable HCC resulted in 66.1% of tumor response with acceptable toxicity, and the radiation dose seems to be a significant prognostic factor in RT response for HCC

    Purpose: To examine the safety and efficacy of Cyberknife stereotactic body radiation therapy (SBRT) and its effect on survival in patients of recurrent hepatocellular carcinoma (HCC). Methods and Materials: This was a matched-pair study. From January 2008 to December 2009, 36 patients with 42 lesions of unresectable recurrent HCC were treated with SBRT. The median prescribed dose was 37 Gy (range, 25 to 48 Gy) in 4–5 fractions over 4–5 consecutive working days. Another 138 patients in the historical control group given other or no treatments were selected for matched analyses. Results: The median follow-up time was 14 months for all patients and 20 months for those alive. The 1- and 2-year in-field failure-free rates were 87.6% and 75.1%, respectively. Out-field intrahepatic recurrence was the main cause of failure. The 2-year overall survival (OS) rate was 64.0%, and median time to progression was 8.0 months. In the multivariable analysis of all 174 patients, SBRT (yes vs. no), tumor size (≤4 cm vs. >4 cm), recurrent stage (stage IIIB/IV vs. I) and Child-Pugh classification (A vs. B/C) were independent prognostic factors for OS. Matched-pair analysis revealed that patients undergoing SBRT had better OS (2-year OS of 72.6% vs. 42.1%, respectively, p = 0.013). Acute toxicities were mild and tolerable. Conclusion: SBRT is a safe and efficacious modality and appears to be well-tolerated at the dose fractionation we have used, and its use correlates with improved survival in this cohort of patients with recurrent unresectable HCC. Out-field recurrence is the major cause of failure. Further studies of combinations of SBRT and systemic therapies may be reasonable.

  11. Epidemiology of hepatocellular carcinoma: target population for surveillance and diagnosis.

    2018-01-01

    Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer mortality worldwide. Incidence rates of liver cancer vary widely between geographic regions and are highest in Eastern Asia and sub-Saharan Africa. In the United States, the incidence of HCC has increased since the 1980s. HCC detection at an early stage through surveillance and curative therapy has considerably improved the 5-year survival. Therefore, medical societies advocate systematic screening and surveillance of target populations at particularly high risk for developing HCC to facilitate early-stage detection. Risk factors for HCC include cirrhosis, chronic infection with hepatitis B virus (HBV), hepatitis C virus (HCV), excess alcohol consumption, non-alcoholic fatty liver disease, family history of HCC, obesity, type 2 diabetes mellitus, and smoking. Medical societies utilize risk estimates to define target patient populations in which imaging surveillance is recommended (risk above threshold) or in which the benefits of surveillance are uncertain (risk unknown or below threshold). All medical societies currently recommend screening and surveillance in patients with cirrhosis and subsets of patients with chronic HBV; some societies also include patients with stage 3 fibrosis due to HCV as well as additional groups. Thus, target population definitions vary between regions, reflecting cultural, demographic, economic, healthcare priority, and biological differences. The Liver Imaging Reporting and Data System (LI-RADS) defines different patient populations for surveillance and for diagnosis and staging. We also discuss general trends pertaining to geographic region, age, gender, ethnicity, impact of surveillance on survival, mortality, and future trends.

    The purpose of this study was to investigate the clinical outcomes of bland embolization using superabsorbent polymer microspheres (SAP-TAE) as an initial therapeutic option for previously untreated hepatocellular carcinoma (HCC) ineligible for resection or ablation. Fifty-nine patients with previously untreated HCC unamenable to surgery or ablation underwent bland embolization using 100- to 200-μm reconstituted SAP particles (SAP-TAE) as the initial treatment. SAP-TAE was repeated as needed based on tumor response but was switched to chemoembolization when necessary to control residual or progressive tumor. Early tumor response was assessed by contrast-enhanced CT according to RECIST and EASL criteria 1 month after the initial SAP-TAE. The overall survival was calculated using the Kaplan-Meier method. The overall mean follow-up period was 30.6 months (range, 7-59 months). A total of 121 sessions of SAP-TAE were performed, with 1-5 sessions per patient (mean, 2.1 sessions). The mean period of repeated SAP-TAE was 15.6 months (range, 1-51 months), and it exceeded 1 and 2 years in 32 (54%) and 15 (25%) patients, respectively. Thirteen (22%) patients underwent repeated SAP-TAE alone, and the remaining 46 (78%) patients underwent subsequent chemoembolization. No major complication was observed and postembolization syndrome was minimal after SAP-TAE in all patients. Response rate was 14% and 66% by RECIST and EASL criteria, respectively. Overall survival rates were 100% and 83% at 1 and 2 years, respectively, and median survival time was 30 months. In conclusion, SAP-TAE was a safe and repeatable option as the induction therapy for HCC unamenable to surgery or ablation, despite the high incidence of converting to TACE during the total course.

    AIM:To evaluate the relationship between a positive family history of primary liver cancer and hepatocellular carcinoma (HCC) development in Korean HCC patients.METHODS:We studied a total of 2242 patients diagnosed with HCC between January 1990 and July 2008,whose family history of primary liver cancer was clearly described in the medical records.RESULTS:Of the 2242 patients,165 (7.4%) had a positive family history of HCC and 2077 (92.6%) did not.The male to female ratio was 3.6:1,and the major causes of HCC were chronic hepatitis B virus (HBV) infection in 75.1%,chronic hepatitis C virus infection in 13.2% and alcohol in 3.1%.The median ages at diagnosis in the positive-and negative-history groups were 52 years (range:29-79 years) and 57 years (range:18-89 years),respectively (P < 0.0001).Furthermore,among 1713 HCC patients with HBV infection,the number of patients under 45 years of age out of 136 patients with positive family history was 26 (19.1%),whereas those out of 1577 patients with negative family history was 197 (12.5%),suggesting that a positive family history may be associated with earlier development of HCC in the Korean population (P =0.0028).CONCLUSION:More intensive surveillance maybe recommended to those with a positive family history of HCC for earlier diagnosis and proper management especially when HBV infection is present.

    Abstract Sorafenib is the only Food and Drug Administration (FDA)-approved first-line therapy shown to have survival benefit for patients with advanced hepatocellular carcinoma (HCC). Patients with advanced HCC are often but not exclusively transferred from non-oncologists to oncologists to initiate systemic therapy. The objective of this study was to assess whether sorafenib prescribing by non-oncologists has any impact on utilization, adverse effects, cost or outcome. This was a retrospective cohort study utilizing data from patients prescribed sorafenib for HCC within Veterans Health Administration hospitals with 100% chart abstraction to confirm HCC diagnosis, identify prescribing provider specialty (oncology versus gastroenterology/hepatology), and obtain data required for cancer staging by the Barcelona Clinic Liver Cancer (BCLC) system. The primary outcome was overall survival from the time of sorafenib prescription. A total of 4903 patients who prescribed sorafenib for HCC were identified, for whom 340 patients (6.9%) were prescribed drug by a non-oncologist (Onc). BCLC Stage, age, Child–Turcotte–Pugh score, and comorbidity indices were similar between patients prescribed sorafenib by oncologists and non-oncologists. Oncologists more often discontinued sorafenib due to progression, whereas non-oncologists were more likely to continue sorafenib until death resulting in greater pill utilization and cost. Overall survival in both unadjusted and multivariable models showed no significant impact of prescriber type on survival (222 vs 217 days, P = .96), confirmed with propensity-matched subcohorts. Similar survival outcomes were observed for patients with HCC prescribed sorafenib by non-oncologists and oncologists, suggesting that non-oncologists with expertise in the management of HCC can safely and effectively administer sorafenib.

    The striking gender disparity observed in the incidence of hepatocellular carcinoma (HCC) suggests an important role of sex hormones in HCC pathogenesis. Though the studies began as early as in 1980s, the precise role of sex hormones and the significance of their receptors in HCC still remain poorly understood and perhaps contribute to current controversies about the potential use of hormonal therapy in HCC. A comprehensive review of the existing literature revealed several shortcomings associated with the studies on estrogen receptor (ER) and androgen receptor (AR) in normal liver and HCC. These shortcomings include the use of less sensitive receptor ligand binding assays and immunohistochemistry studies for ERα alone until 1996 when ERβ isoform was identified. The animal models of HCC utilized for studies were primarily based on chemical-induced hepatocarcinogenesis with less similarity to virus-induced HCC pathogenesis. However, recent in vitro studies in hepatoma cells provide newer insights for hormonal regulation of key cellular processes including interaction of ER and AR with viral proteins. In light of the above facts, there is an urgent need for a detailed investigation of sex hormones and their receptors in normal liver and HCC. In this review, we systematically present the information currently available on androgens, estrogens and their receptors in normal liver and HCC obtained from in vitro, in vivo experimental models and clinical studies. This information will direct future basic and clinical research to bridge the gap in knowledge to explore the therapeutic potential of hormonal therapy in HCC. 2008 The WJG Press.

    This study is to establish a predictive index (PI) model of 5-year survival rate for patients with hepatocellular carcinoma (HCC) after radical resection and to evaluate its prediction sensitivity, specificity, and accuracy.Patients underwent HCC surgical resection were enrolled and randomly divided into prediction model group (101 patients) and model evaluation group (100 patients). Cox regression model was used for univariate and multivariate survival analysis. A PI model was established based on multivariate analysis and receiver operating characteristic (ROC) curve was drawn accordingly. The area under ROC (AUROC) and PI cutoff value was identified.Multiple Cox regression analysis of prediction model group showed that neutrophil to lymphocyte ratio, histological grade, microvascular invasion, positive resection margin, number of tumor, and postoperative transcatheter arterial chemoembolization treatment were the independent predictors for the 5-year survival rate for HCC patients. The model was PI = 0.377 × NLR + 0.554 × HG + 0.927 × PRM + 0.778 × MVI + 0.740 × NT - 0.831 × transcatheter arterial chemoembolization (TACE). In the prediction model group, AUROC was 0.832 and the PI cutoff value was 3.38. The sensitivity, specificity, and accuracy were 78.0%, 80%, and 79.2%, respectively. In model evaluation group, AUROC was 0.822, and the PI cutoff value was well corresponded to the prediction model group with sensitivity, specificity, and accuracy of 85.0%, 83.3%, and 84.0%, respectively.The PI model can quantify the mortality risk of hepatitis B related HCC with high sensitivity, specificity, and accuracy.

    The aim of the present study was to evaluate the outcomes of a multimodal treatment approach of hepatocellular carcinoma (HCC) in a tertiary hepatobiliary specialty center. A total of 294 consecutive patients treated for HCC were retrospectively analyzed. Two hundred sixteen patients (73.4%) were men and 78 (26.6%) were women. Liver resection (LR) was performed in 201 patients (68.4%), liver transplantation (LT) in 19 patients (6.5%), radiofrequency ablation (RFA) in 74 patients (25.1%), and 56 (19%) patients received adjuvant systemic chemotherapy. The median follow-up was 15.7 mo (range 0.1-90.3). Five-year overall survival and recurrence rates were 28% and 26.8%, respectively. Serum AFP > 43.8ng/ml (p = 0.005), BCLC C/D (p = 0.006) and JIS 3/4/5 classifications (p = 0.02) were independent negative prognostic factors for overall survival, while JIS 3/4/5 (p = 0.01) and BCLC C/D (p = 0.01) classifications, tumors larger than 6.5cm (p = 0.001) and RFA (p = 0.02) were independent predictors for recurrence. The current treatment of HCC should be multimodal, and therapeutic modalities and their combinations should be tailored to each patient. LT represents the best therapeutic option for patients with HCC in the setting of cirrhosis. Resection remains a good option in cirrhotic patients, while RFA is a safe and effective procedure for small tumors.

    This study evaluated the usefulness of magnetic resonance imaging (MRI) in the qualitative diagnosis of small hepatocellular carcinoma (HCC). A total of 20 nodules were examined in 18 patients who had HCC 2 cm or less in diameter. Pathological examination classified them into two groups: homogeneous lesions (n=14: grade I, 5; grade I+II, 3; grade III, 4; grade II+III, 2) and heterogeneous lesions (n=6). T1-weighted imaging in the group of homogeneous lesions revealed a higher signal intensity in HCC nodules of grade I than the surrounding hepatic tissue and various signal intensities in those of the other grades. T2-weighted imaging, on the other hand, revealed iso-intensity in 4 nodules of grade I and hypo-intensity in the other; and hyper-intensity in all nodules of the other grades. In the group of heterogeneous lesions, 2 nodules (focal fatty change) were shown as mixed intensity on T1-weighted images and homogenous intensity on T2-weighted images. The other four nodules (grade II within grade I) were shown as homogenous intensity on T1-weighted images; one was shown as iso-intensity, two as hyper-intensity, and one as mixed intensity on T2-weighted images. The tumor-liver contrast and the contrast-to-noise ratio were significantly higher on T1-weighted images than on T2-weighted images in 5 HCC nodules of grade I. In the other nodules, including grade II or greater, on the contrary, these parameters were significantly higher on T2-weighted images than T1-weighted images. (N.K.)

    Full Text Available Tatsuo Kanda, Osamu Yokosuka Department of Gastroenterology and Nephrology, Chiba University, Graduate School of Medicine, Chiba, Japan Abstract: Hepatocellular carcinoma (HCC is one of the male-dominant liver diseases with poor prognosis, although treatments for HCC have been progressing in the past decades. Androgen receptor (AR is a member of the nuclear receptor superfamily. Previous studies reported that AR was expressed in human HCC and non-HCC tissues. AR is activated both ligand-dependently and ligand-independently. The latter is associated with a mitogen-activated protein kinase–, v-akt murine thymoma viral oncogene homolog 1–, or signal-transducer and activator of transcription–signaling pathway, which has been implicated in the development of HCC. It has been reported that more than 200 RNA expression levels are altered by androgen treatment. In the liver, androgen-responsive genes are cytochrome P450s, transforming growth factor , vascular endothelial growth factor, and glucose-regulated protein 78 kDa, which are also associated with human hepatocarcinogenesis. Recent studies also revealed that AR plays a role in cell migration and metastasis. It is possible that cross-talk among AR-signaling, endoplasmic reticulum stress, and innate immune response is important for human hepatocarcinogenesis and HCC development. This review shows that AR could play a potential role in human HCC and represent one of the important target molecules for the treatment of HCC. Keywords: vascular endothelial growth factor, angiogenesis, glucose-regulated protein 78 kDa, hepatocarcinogenesis, molecular targets

    Most patients with a hepatocellular carcinoma (HCC) have an underlying chronic liver inflammation, which causes a continuous damage leading to liver cirrhosis and eventually HCC. However, only a minority of cirrhotic patients develop HCC. To assess a possible differential impact of liver inflammation in patients developing HCC versus patients remaining tumor-free, we designed a longitudinal study and analysed liver tissue of the same patients (n = 33) at two points in time: once when no HCC was present and once several years later when an HCC was present. As a control group, we followed cirrhotic patients (n = 37) remaining tumor-free over a similar time frame. We analysed cell damage and senescence of hepatocytes by measuring γ-H2AX positivity, p16 INK4 and p21 WAF/Cip1 expression, nuclear size, and telomere length. γ-H2AX positivity, p16 INK4 and p21 WAF/Cip1 expression, in the first liver biopsy was similar in patients developing HCC later on and cirrhotic patients remaining tumor free. In contrast, γ-H2AX positivity, p16 INK4 and p21 WAF/Cip1 expression, was significantly higher in the second non-tumoral liver biopsy of HCC patients than in the control patients. Consequently, the individual increase in γ-H2AX positivity, p16 INK4 and p21 WAF/Cip1 expression, from the first biopsy to the second biopsy was significantly higher in patients developing HCC than in patients remaining tumor free. In addition, changes in nuclear size and telomere length revealed a more pronounced cell aging in patients developing HCC than in patients remaining tumor free. Hepatocytes from patients developing HCC go through more pronounced cell damage and senescence in contrast to cirrhotic patients remaining tumor free. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.
