    Irreversible electroporation (IRE) is a novel image-guided ablation technique that is increasingly used to treat locally advanced pancreatic carcinoma (LAPC). We describe a 67-year-old male patient with a 5 cm stage III pancreatic tumor who was referred for IRE. Because the ventral approach for electrode placement was considered dangerous due to vicinity of the tumor to collateral vessels and duodenum, the dorsal approach was chosen. Under CT-guidance, six electrodes were advanced in the tumor, approaching paravertebrally alongside the aorta and inferior vena cava. Ablation was performed without complications. This case describes that when ventral electrode placement for pancreatic IRE is impaired, the dorsal approach could be considered alternatively. PMID:25288173

    Full Text Available Pancreatic cancer patients present late in their course and surgical resection as a modality of treatment is of limited value. Majority develop loco-regional failure and distant metastasis, therefore, adjuvant therapy comprising of radiotherapy and chemotherapy are useful treatment options to achieve higher loco-regional control. Specialized irradiation techniques like intra-operative radiotherapy that help to increase the total tumor dose have been used, however, controvertible survival benefit was observed. Various studies have shown improved median and overall survival with chemoradiotherapy for advanced unresectable pancreatic carcinoma. The role of new agents such as topoisomerase I inhibitors also needs further clinical investigations.

  5. The Problems of Radiofrequency Ablation as an Approach for Advanced Unresectable Ductal Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Advanced ductal pancreatic carcinoma (PC) remains a challenge for current surgical and medical approaches. It has recently been claimed that radiofrequency ablation (RFA) may be beneficial for patients with locally advanced or metastatic PC. Using the MEDLINE database, we found seven studies involving 106 patients in which PC was treated using RFA. The PC was mainly located in the pancreatic head (66.9%) with a median size of 4.6 cm. RFA was carried out in 85 patients (80.1%) with locally advanced PC and in 21 (19.9%) with metastatic disease. Palliative surgical procedures were carried out in 41.5% of the patients. The average temperature used was 90 °C (with a temperature range of 30–105 °C) and the ratio between the number of passes of the probe and the size of the tumor in centimeters was 0.5 (range of 0.36–1). The median postoperative morbidity and mortality were 28.3% and 7.5%, respectively; the median survival was 6.5 months (range of 1–33 months). In conclusion, RFA is a feasible technique: however, its safety and long-term results are disappointing; Thus, the RFA procedure should not be recommended in clinical practice for a PC patient

    Materials and Methods. From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated. Results. There were 20 patients (9 men, 11 women; mean age 58 years identified. The primary tumor was located in the pancreatic head (n=9, 45%, in pancreatic tail (n=9, 45%, and in the papilla Vateri (n=2, 10%. Metastases were located in the liver (n=14, 70%, peritoneum (n=5, 25%, and omentum majus (n=2, 10%. Lymphnode metastases were present in 16 patients (80%. All patients received resection of their tumors together with metastasectomy. Pylorus preserving duodenopancreatectomy was performed in 8 patients, distal pancreatectomy in 8, duodenopancreatectomy in 2, and total pancreatectomy in 2. Morbidity was 45% and there was no perioperative mortality. Median postoperative survival was 10.7 months (2.6–37.7 months which was not significantly different from a matched-pair group of patients who underwent pancreatic resection for UICC adenocarcinoma of the pancreas (median survival 15.6 months; P=.1. Conclusion. Pancreatic resection for M1 periampullary cancer of the pancreas can be performed safely in well-selected patients. However, indication for surgery has to be made on an individual basis.

  8. Evaluation of the Efficacy of Combined Continuous Arterial Infusion and Systemic Chemotherapy for the Treatment of Advanced Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Purpose. To evaluate the effects of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in patients with advanced pancreatic carcinoma. Methods. CTAI was performed in 17 patients with stage IV pancreatic cancer with (n = 11) or without (n = 6) liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The inferior pancreatic artery (IPA) was embolized to achieve delivery of the pancreatic blood supply through only the celiac artery. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. Treatment effects were evaluated based on the primary tumor size, liver metastasis, and survival time and factors such as tumor size, tumor location, and stage of pancreatic carcinoma; the embolized arteries were analyzed with respect to treatment effects and prognosis. Results. A catheter was fixed in the gastroduodenal artery and splenic artery in 10 and 7 patients, respectively. Complete peripancreatic arterial occlusion was successful in 10 patients. CT showed a decrease in tumor size in 6 of 17 (35%) patients and a decrease in liver metastases in 6 of 11 (55%) patients. The survival time ranged from 4 to 18 months (mean ± SD, 8.8 ± 1.5 months). Complete embolization of arteries surrounding the pancreas was achieved in 10 patients; they manifested superior treatment effects and prognoses (p < 0.05). Conclusion. In patients with advanced pancreatic cancer, long-term CTAI with systemic chemotherapy appeared to be effective not only against the primary tumor but also against liver metastases. Patients with successfully occluded peripancreatic arteries tended to survive longer

    BACKGROUND AND PURPOSE: The majority of patients with pancreatic cancer have advanced disease at the time of diagnosis and are not amenable for surgery. Stereotactic radiotherapy (SRT) may be an alternative treatment for patients with locally advanced disease. The effect of SRT was investigated...... (NC) or progression (PD) after treatment. Six patients had local tumour progression, but only one patient had an isolated local failure without simultaneous distant metastasis. Median time to local or distant progression was 4.8 months. Median survival time was 5.7 months and only 5% were alive 1 year...... after treatment. Acute toxicity reported 14 days after treatment was pronounced. There was a significant deterioration of performance status (P=0.008), more nausea (P=0.001) and more pain (P=0.008) after 14 days compared with base-line. However, 8 of 12 patients (66%) improved in performance status...

    2015-05-01

    Full Text Available It is well known that the prognosis of pancreatic cancer is extremely poor, even when treated with radical surgery. The overall 5 year survival rate following surgical intervention is around 10%.With the increasing use of CT scans for other reasons not related to pancreas, a variety of neoplastic and non - neoplastic lesions are increasingly encountered in clinical practice. The distinction of these lesions has significant therapeutic and prognostic implications. Regarding ductal carcinoma, key distinguishing features from chronic pancreatitis and a discussion of the concept of pancreatic intraepithelial neoplasia ( PanIN are included. Precursors, mo lecular carcinogenesis, risk factors and different morphological patterns of tumors arising from exocrine pancreas are discussed. Research on early detection is ongoing. Screening of people with a family history of hereditary pancreatitis plays an importan t role in the early detection of ductal carcinoma of pancreas.

  14. Comparison of Intrahepatic and Pancreatic Perfusion on Fusion Images Using a Combined SPECT/CT System and Assessment of Efficacy of Combined Continuous Arterial Infusion and Systemic Chemotherapy in Advanced Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Purpose. The purpose of this study was to compare intrahepatic and pancreatic perfusion on fusion images using a combined single-photon emission computed tomography (SPECT)/CT system and to evaluate the efficacy of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in the treatment of advanced pancreatic carcinoma. Materials and Methods. CTAI was performed in 33 patients (22 men, 11 women; age range, 35-77 years; mean age, 60 years) with stage IV pancreatic cancer with liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. In all patients we obtained fusion images using a combined SPECT/CT system. Pancreatic perfusion on fusion images was classified as perfusion presence or as perfusion absent in the pancreatic cancer. Using WHO criteria we recorded the tumor response after 3 months on multislice helical CT scans. Treatment effects were evaluated based on the pancreatic cancer, liver metastasis, and factors such as intrahepatic and pancreatic perfusion on fusion images. For statistical analysis we used the chi-square test; survival was evaluated by the Kaplan Meier method (log-rank test). Results. On fusion images, pancreatic and intrahepatic perfusion was recorded as hot spot and as homogeneous distribution, respectively, in 18 patients (55%) and as cold spot and heterogeneous distribution, respectively, in 15 (45%). Patients with hot spot in the pancreatic tumor and homogeneous distribution in the liver manifested better treatment results (p < 0.05 and p < 0.01, respectively). Patients with hot spot both in the pancreatic cancer and in the liver survived longer than those with cold spot in the pancreatic cancer and heterogeneous distribution in the liver (median ± SD, 16.0 ± 3.7 vs. 8.0 ± 1.4 months; p < 0.05). Conclusions. We conclude that in patients with advanced pancreatic

    Full Text Available Acinar cell pancreatic carcinoma is a rare solid malignant neoplasm. Recent review of the literature showed occasional cases with papillary or papillocystic growth patterns, ranging from 2 to 5 cm in diameter. We report a large 10 cm pancreatic tumor with papillocystic pathology features involving the pancreatic head. The growth pattern of these tumors could be mistaken for intraductal papillary mucinous tumors or other pancreatic cystic neoplasms.

    2007-01-01

    Background. Current therapies for adenocarcinoma of the pancreas do not improve the life expectancy of patients. Methods. In a non-randomized pilot trail we tested whether a local therapy based upon an adenoviral gene transfer of wild type p53 in combination with gemcitabine administration would be safe in patients with liver metastases due to pancreatic carcinoma. We report on the clinical course of three patients with respect to safety, tolerability and tumor response. Results. Transient grade III toxicities occurred with fever, leucopenia, elevation of AP, ALT, AST, GGT, while grade IV toxicity occurred for bilirubin only. Laboratory tests suggested disseminated intravascular coagulation in all three patients, but fine needle biopsies of liver did not show any histological evidence of thrombus or clot formation. Progression of liver metastases was documented in one and stable disease in another patient two months after treatment. However, a major improvement with regression of the indexed lesion by 80% occurred in a third patient after a single administration of 7.5×1012 viral particles, and time to progression was extended to six months. Conclusion. The combination therapy of viral gene transfer and chemotherapy temporarily controls and diminishes tumor burden. Improvement of the toxicity profile is necessary. Further trials are warranted to improve treatment and life expectancy of patients suffering from fatal diseases such as pancreatic carcinoma. PMID:18333108

    Full Text Available Context Pancreatic metastases are relatively common in advanced lung cancers (both small cell lung carcinoma and non-small cell lung carcinoma, but metastasis-induced acute pancreatitis is very unusual. Case report A 51-year-old woman with small cell carcinoma of the lung developed acute pancreatitis as the initial manifestation. Abdominal ultrasonography revealed multiple pancreatic metastases which were confirmed by magnetic resonance imaging. Conventional treatment did not improve her condition. However, aggressive chemotherapy resulted in a dramatic recovery from the acute pancreatitis and significant improvement in her general condition. Conclusion When cases of acute pancreatitis in patients with small cell lung carcinoma are encountered, we must consider the possibility of metastasis-induced acute pancreatitis and that, should pancreatic metastases be found in these patients, chemotherapy may provide substantial benefit.

    Pancreatic carcinoma is the fourth-leading cause of cancer death and is characterized by early invasion and metastasis. The developmental program of epithelial-mesenchymal transition (EMT) is of potential importance for this rapid tumor progression. During EMT, tumor cells lose their epithelial characteristics and gain properties of mesenchymal cells, such as enhanced motility and invasive features. This review will discuss recent findings pertinent to EMT in pancreatic carcinoma. Evidence for and molecular characteristics of EMT in pancreatic carcinoma will be outlined, as well as the connection of EMT to related topics, e.g., cancer stem cells and drug resistance.

  2. CT of the superior mesenteric artery root in pancreatitis and pancreatic carcinoma

    International Nuclear Information System (INIS)

    Previous reports suggested that pancreatitis does not produce CT changes in the region of the root of the superior mesenteric artery (SMA) while pancreatic carcinoma does. The authors have reviewed 103 CT studies from patients with proved pancreatitis (n = 61) or pancreatic carcinoma (n = 42). Masked CT studies (obscuring all regions except the root of the SMA) were evaluated for infiltration of the fat around the SMA, adjacent lymph nodes, focal mass abutting the SMA, and mass circumferentially encasing the SMA. Streaky infiltration around the SMA was seen in patient with pancreatitis (58%) and pancreatic carcinoma (52%). Lymph nodes were seen in both pancreatitis (28%) and carcinoma (17%). Focal mass abutting the SMA was seen in pancreatitis (7%) and carcinoma (26%). Encasement of the SMA was seen only in carcinoma (17%). Both pancreatitis and pancreatic carcinoma can produce CT findings in the region of the root of the SMA. Encasement of the SMA was the only finding specific to patients with pancreatic carcinoma

    Background The coagulation function in patients with pancreatic carcinoma is abnormal and the reason is not very clear. In this study, we retrospectively analyzed the coagulation function in patients with pancreatic carcinoma.Methods From June 2004 to December 2007, 132 patients received diagnosis and treatment in our hospital. The coagulative parameters including the prothrombin time, activated partial thromboplastin time, and fibrinogen levels were collected and studied retrospectively.Results The average fibrinogen levels in patients with pancreatic carcinoma, (476.21±142.05) mg/dl, were significantly higher than in patients with cholangiolithiasis, (403.28±126.41) mg/dl (P 0.05).Conclusions The level of fibrinogen in patients with pancreatic carcinoma was elevated. The elevated fibrinogen level may be associated with invasiveness and lymphatic metastasis. Using vitamin K in perioperation management did not reduce intraoperative blood loss.

    Ascarias lumbricoides infestation is endemic in tropical countries. Most infections are asymptomatic, but it can produce a wide spectrum of manifestations including hepatobiliary and pancreatic complications. There are reports of association of biliary ascariasis with bilary malignancies in the past, but same is not known for pancreatic ascariasis. We report a case of association of periampullary malignancy with pancreatic ascariasis.

  6. Maintenance chemotherapy after chemoradiation improves survival of patients with locally advanced pancreatic carcinoma. A retrospective analysis of prospectively recruited patients

    International Nuclear Information System (INIS)

    Background and purpose: currently, there is no treatment standard for patients with locally advanced pancreatic cancer (PaCa) after chemoradiation. The aim of the present study was to retrospectively assess overall survival and toxicity of chemotherapy in addition to chemoradiation in this patient group. Patients and methods: three-dimensional conformal irradiation to the primary tumor (55.8 Gy) and the lymphatics (50.4 Gy) was combined with 5-fluorouracil- or gemcitabine-based chemotherapy followed by additional chemotherapy with gemcitabine until progression or no further treatment. Decision for chemotherapy was taken at the discretion of the attending physician considering the patient's desire. Results: a total of 172 patients were addressed to the local tumor board. Patients with (neo)adjuvant treatment or metastatic disease were excluded (n = 90). 82 patients were treated with chemoradiation and had additional chemotherapy (n = 40) or no further treatment (n = 42). Characteristics of the two groups were equally distributed. Patients with chemotherapy had significantly longer overall survival as compared to patients without (13 months vs. 8 months; p < 0.0001; median survival = 10.7 months for all patients). Acute toxicity of maintenance chemotherapy was relatively mild. Conclusion: maintenance chemotherapy after chemoradiation for patients with locally advanced PaCa may significantly increase survival rates without severe side effects and is therefore recommended as standard treatment following chemoradiation.

    CTV definition in exclusive or adjuvant radiation therapy of pancreatic carcinoma is essentially based on the opinion of "expert" authors and on the knowledge of lymphatic pathways. The subject has been widely debated. Radiotherapy treatments of the entire upper abdomen (liver and pancreatic region), pancreas and lymph node stations, to volumes focused on macroscopic tumor only, have been proposed. Carcinoma of exocrine pancreas is characterized by the frequent, early appearance of metastasis via the lymphatic route. Most commonly involved lymph node stations include those of the celiac trunk, superior mesenteric, peripancreatic, lumboaortic lymph nodes, those of the hepatic portal (the latter in particular for pancreatic head tumors) and of the hilum of spleen (the latter in particular for pancreatic tail tumors). The possible multicentricity of pancreatic carcinoma, most likely due to intraductal spread, should lead to the inclusion in the CTV of the entire pancreatic parenchyma. This should be considered also for the frequent perineural intra- or extrapancreatic spread of pancreatic carcinoma present also in small tumors (T1). In extrapancreatic spread the retropancreatic adipose tissue should be included in the CTV at least at the GTV level. At the present state of knowledge, in the absence of pattern of failure analysis and of comparison of different treatment approaches, in terms of the definition of volumes of interest, CTV definitions which include lymphatic drainage stations, most part of pancreatic parenchyma and retropancreatic adipose tissue seem justified especially in treatments for cure. In palliation, the CTV may be limited to the GTV and the adipose tissue behind it. PMID:15018319

    The aim of this study was to clarify the characteristics of pancreatic head carcinomas mainly invading the groove between the duodenum and the pancreatic head. Nine patients with pathologically proven pancreatic head carcinomas underwent thin-slice dynamic CT, MR imaging, duodenal endoscopy, and angiography (seven patients). Plate-like masses within the groove region were seen in all cases, which showed hypointensity on T1-weighted images and slight hyperintensity on T2-weighted MR images. The masses appeared hypovascular in the early phase and delayed enhancement in the late phase of dynamic CT and MR imaging. On MR cholangiopancreatography, stenosis of intrapancreatic common bile duct was seen in all patients, whereas stenosis of the main pancreatic duct was seen in only three cases. Endoscopy revealed luminal narrowing of the duodenum in all patients, and duodenal mucosal biopsy demonstrated adenocarcinoma in seven patients. Abdominal arteriography showed serrated encasement of peripancreatic arteries in seven patients who received angiographic examinations. The CT and MR imaging findings of groove pancreatic carcinomas resemble those of groove pancreatitis. Differential diagnosis may be achieved by the pathological diagnosis of a biopsy specimen of the duodenal mucosa and arterial encasement on arteriography. (orig.)

  9. Evaluation of inoperable pancreatic carcinoma based on tumor metastasis

    International Nuclear Information System (INIS)

    Many pancreatic cancers are detected only after they are far advanced, and thus show a poor prognosis. We evaluated the survival of patients with inoperable pancreatic carcinoma, and strategy treatment. Subjects were 72 persons with advanced inoperable pancreatic carcinoma selected from among 144 examined at our department from May 1992 to March 2001. Patient factors (age, gender, and nutrition), tumor factors (hepatic metastasis, peritoneal dissemination, and distant metastasis), and treatment (radiotherapy, systemic chemotherapy, and hepatic arterial infusion therapy (HAI)) were studied and survival evaluated statistically. Overall mean survival was 175 days and the 1-year survival ratio was 13.5%. With multivariate analysis, prognostic factors were hepatic metastasis and radiotherapy. We therefore re-evaluated 56 patients treated with radiotherapy. In the group with no hepatic metastasis whose mean survival was 247 days, the prognostic factor was systemic chemotherapy. In the group with hepatic metastasis, mean survival was 140 days and the prognostic factor was the prognostic nutritional index (PNI) on admission. HAI was also a significant factor, which prolonged survival time with univariate analysis. Radiotherapy will be conducted for all inoperable pancreatic carcinomas. For the group with no hepatic metastasis, systemic chemotherapy is effective and for the group with hepatic metastasis. HAI will be selected. (author)

    Purpose: To clarify if the portal venous phase is helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis. Materials and methods: MDCT and MRI of groove pancreatic carcinomas (n = 7) and groove pancreatitis (n = 15) were retrospectively reviewed by two radiologists independently. The signal intensity on T2-weighted images was subjectively assessed. The presence or absence of common bile duct (CBD) and main pancreatic duct (MPD) strictures, calcifications, and cystic lesions was evaluated. Additionally, the appearance of groove pancreatic carcinoma and that of groove pancreatitis in the portal venous phase on dynamic MDCT and MRI were compared. Results: There were no significant differences in the signal intensity on T2-weighted images and in the presence or absence of CBD and MPD strictures, calcifications, and cystic lesions between groove pancreatic carcinomas and groove pancreatitis. However, patchy focal enhancement in the portal venous phase was more commonly observed in groove pancreatitis than groove pancreatic carcinoma (Reviewers 1 and 2: 14/15 [93.3%] vs. 1/7 [14.3%], P < 0.0001). In addition, peripheral enhancement was only seen in groove pancreatic carcinomas (Reviewer 1: 4/7 [57.1%] vs. 0/15 [0%], P < 0.005, and Reviewer 2: 3/7 [42.9%] vs. 0/15 [0%], P < 0.05). Conclusion: The portal venous phase may be helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis.

    Objective: To evaluate the activity and safety of combination chemotherapy with gemcitabine plus oxaliplatin (GEMOX regimen) in patients of advanced pancreatic carcinoma. Methods: 30 patients with advanced pancreatic cancer were enrolled into this study. All patients received gemcitabine 1000 mg/m2, given by 30-minute intravenous infusion, on days 1 and 8 of each 21-day cycle. Oxaliplatin 100 mg/m2 was administered as a 2 h infusion on day 1 of each 21 day. Clinical outcomes for patients treated with two cycles of chemotherapy were evaluated according to WHO criteria. Results: All 30patients were eligible for effectiveness and safety analysis. Objective response rate was approximately 20.0%. Clinical benefit response (CBR) was a composite of assessment of pain, performance status and body weight. The pain relief rate, improvement rate of performance status and body weight were 53.3%, 46.7% and 36.7%, respectively. The main adverse effects were bone marrow depression, peripheral nerve toxicity and gastrointestinal reaction. There was no treatment-related death during the chemotherapy. Conclusion: The high response rate with low toxicity observed in this study suggests that GEMOX regimen may be an effective alternative curative treatment for patients with advanced pancreatic carcinoma and can be used more extensively in clinical practice.

    Full Text Available Context Small cell carcinoma of the lung is an aggressive cancer with gloomy prognosis. Links to acute pancreatitis is extremely rare. Case report We are reporting a 53-year-old patient who was admitted because of acute pancreatitis. She had no history of gallstones, alcohol abuse, medications or any other predisposition for acute pancreatitis. Further investigations of blood, CT of chest abdomen and neck and ultrasound scan of abdomen, bone marrow and neck lymph node biopsies confirmed advanced small cell carcinoma of the lung with hypercalcemia, which was the only definite cause of acute pancreatitis. The patient made good recovery from pancreatitis after controlling the hypercalcemia. She was referred to respiratory team for further management of lung cancer. Conclusion Acute pancreatitis due to hypercalcemia of advanced small cell carcinoma of the lung is an extremely rare condition. Acute pancreatitis due to hypercalcemia should be thoroughly investigated to exclude serious pathology as in our case.

    To evaluate the major prognostic factors in patients with pancreatic carcinoma.Methods : 113 cases of a particular disease were retrospectively analysed and 9 factors for prognosis were studied by muitivaritate analysis with Cox proportional hazards survival model. Survival rate was calculated by Kaplan-Meier estimation. Results:In this group,survival time was 0.1 to 82 months,and the median survival time was 3 months.Overall survival rates at month 6,12,18,36 were 35.6%, 20.3%, 15.9% and 6.2%, respectively.Multivariate analyses revealed significant prognostic factors as follows:jaundice, metastasis, therapy method and synthetic therapy. Conchusion: The prognosis of pancreatic carcinoma is determined by various factors. Jaundice and metastasis are independent predictors of poor survival.Radical operation and synthetic therapy will improve the prognosis.

    2003-01-01

    Full Text Available Abstract Cancer of the exocrine pancreas represents the fifth leading cause of cancer death in the Western population with an average survival after diagnosis of 3 to 6 months and a five-year survival rate under 5%. Our understanding of the molecular carcinogenesis has improved in the last few years due to the development of novel molecular biological techniques. Pancreatic cancer is a multi-stage process resulting from the accumulation of genetic changes in the somatic DNA of normal cells. In this article we describe major genetic alterations of pancreatic cancer, mutations in the proto-oncogene K-RAS and the tumor suppressors INK4A, TP53 and DPC4/SMAD4. The accumulation of these genetic changes leads to a profound disturbance in cell cycle regulation and continuous growth. The knowledge of the underlying molecular mechanisms will offer new therapeutic and diagnostic options and hopefully improve the outcome of this aggressive disease.

  18. Membrane Drug Transporters and Chemoresistance in Human Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Pancreatic cancer ranks among the tumors most resistant to chemotherapy. Such chemoresistance of tumors can be mediated by various cellular mechanisms including dysregulated apoptosis or ineffective drug concentration at the intracellular target sites. In this review, we highlight recent advances in experimental chemotherapy underlining the role of cellular transporters in drug resistance. Such contribution to the chemoresistant phenotype of tumor cells or tissues can be conferred both by uptake and export transporters, as demonstrated by in vivo and in vitro data. Our studies used human pancreatic carcinoma cells, cells stably transfected with human transporter cDNAs, or cells in which a specific transporter was knocked down by RNA interference. We have previously shown that 5-fluorouracil treatment affects the expression profile of relevant cellular transporters including multidrug resistance proteins (MRPs), and that MRP5 (ABCC5) influences chemoresistance of these tumor cells. Similarly, cell treatment with the nucleoside drug gemcitabine or a combination of chemotherapeutic drugs can variably influence the expression pattern and relative amount of uptake and export transporters in pancreatic carcinoma cells or select for pre-existing subpopulations. In addition, cytotoxicity studies with MRP5-overexpressing or MRP5-silenced cells demonstrate a contribution of MRP5 also to gemcitabine resistance. These data may lead to improved strategies of future chemotherapy regimens using gemcitabine and/or 5-fluorouracil

  19. Beer and its Non-Alcoholic Compounds: Role in Pancreatic Exocrine Secretion, Alcoholic Pancreatitis and Pancreatic Carcinoma

    Directory of Open Access Journals (Sweden)

    Peter Feick

    2010-03-01

    Full Text Available : In this article we provide an overview of the newest data concerning the effect of non-alcoholic constituents of alcoholic beverages, especially of beer, on pancreatic secretion, and their possible role in alcoholic pancreatitis and pancreatic carcinoma. The data indicate that non-alcoholic constituents of beer stimulate pancreatic enzyme secretion in humans and rats, at least in part, by direct action on pancreatic acinar cells. Some non-alcoholic compounds of beer, such as quercetin, resveratrol, ellagic acid or catechins, have been shown to be protective against experimentally induced pancreatitis by inhibiting pancreatic secretion, stellate cell activation or by reducing oxidative stress. Quercetin, ellagic acid and resveratrol also show anti-carcinogenic potential in vitro and in vivo. However, beer contains many more non-alcoholic ingredients. Their relevance in beer-induced functional alterations of pancreatic cells leading to pancreatitis and pancreatic cancer in humans needs to be further evaluated.

    Full Text Available Discriminating between focal chronic pancreatitis and pancreatic cancer is always a challenge in clinical medicine. Contrast-enhanced endoscopic ultrasound using Doppler techniques can uniquely reveal different vascularisation patterns in pancreatic tissue alterated by chronic inflammatory processes and even allows a discrimination from pancreatic cancer. This paper will describe the basics of contrast-enhanced high mechanical index endoscopic ultrasound (CEHMI EUS and contrast enhanced low mechanical index endoscopic ultrasound (CELMI EUS and explain the pathophysiological differences of the vascularisation of chronic pancreatitis and pancreatic carcinoma. Furthermore it will discuss how to use these techniques in daily clinical practice.

    Companion animals may serve as valuable models for studying human cancers. Although KRAS is the most commonly mutated gene in human ductal pancreatic cancers (57%), with mutations frequently occurring at codons 12, 13 and 61, human pancreatic acinar cell carcinomas (ACCs) lack activating KRAS mutations. In the present study, 32 pancreatic ACC samples obtained from 14 dogs and 18 cats, including seven metastases, were analyzed for six common activating KRAS mutations located in codons 12 (n = 5) and 13 (n = 1) using Sequenom MassARRAY. No KRAS mutations were found, suggesting that, similar to human pancreatic ACC, KRAS mutations do not play a critical role in feline or canine pancreatic ACC. Due to the similarity of the clinical disease in dogs and cats to that of man, this study confirms that companion animals offer potential as a suitable model for investigating this rare subtype of pancreatic carcinoma.

  5. Epidermal growth factor and its receptors in human pancreatic carcinoma

    International Nuclear Information System (INIS)

    The role of epidermal growth factor (EGF) in oncogenesis and progression of malignant tumors is a subject of vast interest. In this study, radioimmunoassay and radioreceptor assay of EGF were established. EGF contents in malignant and benign pancreatic tumors, in normal pancreas tissue, and in culture media of a human pancreatic carcinoma cell line were determined. EGF receptor binding studies were performed. It was shown that EGF contents in pancreatic carcinomas were significantly higher than those in normal pancreas or benign pancreatic tumors. EGF was also detected in the culture medium of a pancreatic carcinoma cell line. The binding of 125I-EGF to the pancreatic carcinoma cells was time and temperature dependent, reversible, competitive, and specific. Scatchard analysis showed that the dissociation constant of EGF receptor was 2.1 X 10(-9) M, number of binding sites was 1.3 X 10(5) cell. These results indicate that there is an over-expression of EGF/EGF receptors in pancreatic carcinomas, and that an autocrine regulatory mechanism may exist in the growth-promoting effect of EGF on tumor cells

    The present article analyses the main presentations on acute pancreatitis at Digestive Disease Week 2015. Arterial pseudoaneurysm is an uncommon complication of acute pancreatitis (incidence 0.7%) and mortality from this cause is currently anecdotal. Diabetes mellitus has little impact on the clinical course of acute pancreatitis, unlike cirrhosis, which doubles the risk of mortality. Intake of unsaturated fat could be associated with an increased severity of acute pancreatitis and is a confounding factor in studies evaluating the relationship between obesity and morbidity and mortality. PET-CT (positron emission tomography-computed tomography) could be a non-invasive tool to detect infection of collections in acute pancreatitis. Peripancreatic fat necrosis is less frequent than pancreatic fat necrosis and is associated with a better clinical course. If the clinical course is poor, increasing the calibre of the percutaneous drains used in the treatment of infected necrosis can avoid surgery in 20% of patients. The use of low molecular-weight heparin in moderate or severe pancreatitis could be associated with a better clinical course, specifically with a lower incidence of necrosis. In acute recurrent pancreatitis, simvastatin is a promising drug for prophylaxis of new episodes of acute pancreatitis. Nutritional support through a nasogastric tube does not improve clinical course compared with oral nutrition. PMID:26520203

    A 22 years-old female patient who began feeling some pain in the upper hemi abdomen that became intensive after food consumption and the feeling of having eaten too much. The serum amylase levels were within the normal limits. The imaging studies both echography and computerized axial tomography disclosed a well-defined and vascularized tumor mass in the tail of pancreas. She was operated on to completely remove the lesion. The anatomopathological study confirmed the diagnosis of solid and cystic pancreatic papillary carcinoma. Later on, the patient received chemotherapy and radiotherapy. The evolutional imaging tests did not show either local relapses or distant metastasis. The patient responded well to treatment and her health status is good nowadays

    This article reviews advances in the management of acute pancreatitis. Medical treatment has been primarily supportive for this diagnosis, and despite extensive research efforts, there are no pharmacologic therapies that improve prognosis. The current mainstay of management, notwithstanding the ongoing debate regarding the volume, fluid type, and rate of administration, is aggressive intravenous fluid resuscitation. Although antibiotics were used consistently for prophylaxis in severe acute pancreatitis to prevent infection, they are no longer used unless infection is documented. Enteral nutrition, especially in patients with severe acute pancreatitis, is considered a cornerstone in management of this disease. PMID:26895677

  9. CT diagnosis of pancreatitis and carcinoma of the pancreas

    International Nuclear Information System (INIS)

    The article reports on 78 CT scans of surgically diseases of the pancreas, 30 cases of chronic pancreatitis, 12 cases of haemorrhagic-necrotizing pancreatitis, and 36 cases of carcinoma of the pancreas. 12 of these cases were operable, whereas 234 were inoperable. The operable carcinomas were so small that proper diagnosis was effected in 50% only, whereas the inoperable carcinomas eluded CT identification in 17% of the cases only. The most important signs of an operable carcinoma of the pancreas are a well-defined enlargement and inhomogeneity of the parenchyma with reduced contrast, especially on bolus injection, as well as dilatation of the bile duct system. The most essential criteria for inoperability are absence of boundaries, especially towards the dorsal side, with infiltration of the retroperitoneal fatty tissue, and lack of delineation of the large vessels. According to the present state of the art, CT does not supply definite criteria for differentiating between an operable carcinoma of the pancreas and chronic fibrotic pancreatitis. Overstepping of the marginal contours is a reliably distinctive feature between carcinoma and pancreatitis, but it also points to the inoperable nature of the disease. Haemorrhagic-necrotizing pancreatitis is characterized by definite CT criteria, so that diagnosis is easy. Computerised tomography is a valuable diagnostic tool in diseases of the pancreas and can supply conclusive pointers towards the operability of a tumor. (orig.)

  12. Stereotactic Body Radiation Therapy (SBRT) for Unresectable Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Survival in patients with unresectable pancreatic carcinoma is poor. Studies by Mayo Clinic and the Gastrointestinal Tumor Study Group (GITSG) have established combined modality treatment with chemotherapy and radiation as the standard of care. Use of gemcitabine-based chemotherapy alone has also been shown to provide a benefit, but 5‑year overall survival still remains less than 5%. Conventional radiotherapy is traditionally delivered over a six week period and high toxicity is seen with the concomitant use of chemotherapy. In contrast, SBRT can be delivered in 3–5 days and, when used as a component of combined modality therapy with gemcitabine, disruption to the timely delivery of chemotherapy is minimal. Early single-institution reports of SBRT for unresectable pancreatic carcinoma demonstrate excellent local control with acceptable toxicity. Use of SBRT in unresectable pancreatic carcinoma warrants further investigation in order to improve the survival of patients with historically poor outcomes

We investigated the clinicopathological features and outcome of pancreatic ASC patients after surgery. Methods The medical records of 12 patients with pancreatic ASC undergoing surgical treatment (1993 to 2006 were retrospectively reviewed. Survival data of patients with stage IIB pancreatic adenocarcinoma and ASC undergoing surgical resection were compared. Results Symptoms included abdominal pain (91.7%, body weight loss (83.3%, anorexia (41.7% and jaundice (25.0%. Tumors were located at pancreatic head in 5 (41.7% patients, tail in 5 (41.7%, and body in 4 (33.3%. Median tumor size was 6.3 cm. Surgical resection was performed on 7 patients, bypass surgery on 3, and exploratory laparotomy with biopsy on 2. No surgical mortality was identified. Seven (58.3% and 11 (91.7% patients died within 6 and 12 months of operation, respectively. Median survival of 12 patients was 4.41 months. Seven patients receiving surgical resection had median survival of 6.51 months. Patients with stage IIB pancreatic ASC had shorter median survival compared to those with adenocarcinoma. Conclusion Aggressive surgical management does not appear effective in treating pancreatic ASC patients. Strategies involving non-surgical treatment such as chemotherapy, radiotherapy or target agents should be tested.

    AIM: To detect the therapeutic effects of chemical destruction of celiac ganglion in patients with pancreatic carcinoma with intractable pain.METHODS: Ninety-seven cases with advanced pancreatic carcinoma received chemical destruction of celiac ganglion-5 mL pure alcohol injection around celiac artery under ultrasonic guidance. The changes of visual analogue scale (VAS), serum substance P (Sub P),β-endopeptide (β-EP) and T-lymphocyte subtypes level were compared between pre- and post-therapy.RESULTS: Successful rate of puncture was 98.7%, with one failure. No serious complications such as traumatic pancreatitis, pancreatic fistula, abdominal cavity hemorrhage or peritoneal infection occurred. VAS, serum Sub P and β-EP level significantly changed after treatment (8.0 ± 2.3 vs 4.6 ± 2.1, 254.1 ± 96.7 vs 182.4 ± 77.6,3.2 ± 0.8 vs 8.8 ± 2.1, P < 0.01, P < 0.05, P < 0.01)with complete relief rate 54.2%, partial relief rate 21.9%, ineffective rate 12.5% and recurrent rate 10.7%.The T-lymphocyte subtypes level remarkably increased when compared with that of pre-therapy (46.7 ± 3.7 vs 62.5 ± 5.5, P < 0.01).CONCLUSION: Our study suggests that chemical destruction of celiac ganglion under ultrasonic guidance is highly safe, and can evidently relieve cancer pain and improve the cellular immunity in patients with advanced pancreatic carcinoma.

    Pancreatic cancer remains one of the most lethal cancers. These patients often have multiple symptoms, and integrated supportive care is critical in helping them remain well for as long as possible. Fluorouracil-based chemotherapy is known to improve overall survival (OS) by approximately 3 months, compared to the best supportive care alone. A 1997 study comparing gemcitabine and fluorouracil treatment of advanced pancreatic cancer patients showed an improvement in OS of 1 month in patients receiving gemcitabine. Over the next 10 years, multiple randomized studies compared single-agent gemcitabine with combination chemotherapy and showed no effective survival improvement. However, the addition of erlotinib, an epidermal growth factor receptor (EGFR) inhibitor, was associated with a significant improvement in OS of approximately 2 weeks. However, adoption of this regimen has not been widespread because of its limited effect and added toxicity. Two clinical trials have recently prolonged OS in advanced pancreatic cancer patients by almost 1 year. The first compared FOLFIRINOX with gemcitabine alone, and was associated with a significant improvement in median survival. The second compared gemcitabine and nab-paclitaxel with gemcitabine alone, and was associated with improvements in OS. At present, these regimens are considered standard treatment for patients with good performance statuses. PMID:27114434

    Pancreatic cancer remains one of the most lethal cancers. These patients often have multiple symptoms, and integrated supportive care is critical in helping them remain well for as long as possible. Fluorouracil-based chemotherapy is known to improve overall survival (OS) by approximately 3 months, compared to the best supportive care alone. A 1997 study comparing gemcitabine and fluorouracil treatment of advanced pancreatic cancer patients showed an improvement in OS of 1 month in patients receiving gemcitabine. Over the next 10 years, multiple randomized studies compared singleagent gemcitabine with combination chemotherapy and showed no effective survival improvement. However, the addition of erlotinib, an epidermal growth factor receptor (EGFR) inhibitor, was associated with a significant improvement in OS of approximately 2 weeks. However, adoption of this regimen has not been widespread because of its limited effect and added toxicity. Two clinical trials have recently prolonged OS in advanced pancreatic cancer patients by almost 1 year. The first compared FOLFIRINOX with gemcitabine alone, and was associated with a significant improvement in median survival. The second compared gemcitabine and nabpaclitaxel with gemcitabine alone, and was associated with improvements in OS.

    Pancreatic carcinoma has a poor prognosis and early detection is essential for potentially curative resection. Despite the wide array of diagnostic tools, preoperative detection of small pancreatic carcinomas remains difficult. We report a case of small pancreatic carcinoma of the head of pancreas with indeterminate findings on US, ERCP, MRI and EUS which was successfully diagnosed via fusion CT-PET. This case illustrates the utility of CT-PET in the diagnosis of patients with small pancreatic carcinoma with equivocal findings on conventional diagnostic modalities.

    2009-02-01

    Patients with non-resectable pancreatic and biliary tract cancer (cholangiocarcinoma and gallbladder cancer) have a dismal outlook with conventional palliative therapies, with a median survival of 3-9 months and a 5 year survival of less than 3%. Surgery is the only curative treatment but is appropriate in less than 20% of cases, and even then is associated with a 5-year survival of less than 30%. Although most applications of photodynamic therapy (PDT) in gastroenterology have been on lesions of the luminal gut, there is increasing experimental and clinical evidence for its efficacy in cancers of the pancreas and biliary tract. Our group has carried out the only clinical study of PDT in pancreatic carcinoma reported to date, and showed that PDT is feasible for local debulking of pancreatic cancer. PDT has also been used with palliative intent in patients with unresectable cholangiocarcinoma, with patients treated with stenting plus PDT reporting improvements in cholestasis, quality of life and survival compared with historical or randomized controls treated with stenting alone. Further controlled studies are needed to establish the influence of PDT and chemotherapy on the survival and quality of life of patients with pancreatic and biliary tract carcinoma.

  8. Pancreatic Carcinoma Recurrence in the Remnant Pancreas after a Pancreaticoduodenectomy

    Full Text Available Context :We report a rare case of a repeated pancreatic resection in the remnant distal pancreas 18 months after a Whipple R0 procedure. Case report: In September 2003, a 63-yearold man underwent a Whipple procedure with an extended lymphadenectomy, portal vein resection and direct reconstruction for pancreatic cancer. In September 2004, the tumor marker level increased and MR revealed a tumor in the remnant pancreas. There were no findings of invasion into the surrounding tissue or distant metastasis. After three months of systemic chemotherapy and a radiological reevaluation (PET and CT in March 2005, we removed the remnant pancreas. Histopathologically, the tumor was classified as a ductal adenocarcinoma like the tumor which had been removed during the first operation, with infiltration of peripancreatic adipose tissue and a segmentary tract of the transverse mesocolon, without lymph node metastasis. Conclusions :There are very few reports of pancreatic carcinoma recurrence in the remnant pancreas after a pancreaticoduodenectomy in the literature. In most of these cases, it is difficult to assess whether the remnant pancreatic cancer is a recurrence or a second primary cancer. In our patient, the first hypothesis seems to be more realistic due to the brief recurrence-free survival period. Otherwise the high rate of multicentricity in pancreatic cancer may also explain the development of a secondary cancer in the remnant pancreas, even though the interval was relatively brief.

  10. Mitomycin-Induced Interstitial Pneumonitis in a Patient with BRCA2 Associated Metastatic Pancreatic Carcinoma

    Directory of Open Access Journals (Sweden)

    Full Text Available Dear Sir, Interstitial lung diseases are diffuse parenchymal lung diseases, and represent a heterogeneous group of disorders including lymphocytic interstitial pneumonitis, interstitial lung diseases of unknown etiology, including sarcoidosis, idiopathic pulmonary fibrosis, and pulmonary fibrosis associated with connective tissue diseases [1]. Most of the interstitial disorders have a restrictive pattern with reductions in total lung capacity, functional residual capacity, and residual volume [2]. The lung has significant susceptibility to injury from a variety of chemotherapeutic agents (Table 1. The clinician must be familiar with classic chemotherapeutic agents with well-described pulmonary toxicities and must also be vigilant about a host of new agents that may exert adverse effects on lung function [3]. BRCA2 mutations have been known to be associated with higher incidence of breast, ovarian and pancreatic adenocarcinoma [4, 5, 6]. Although present in only a minority of pancreatic cancers, mutations in the BRCA2 gene could provide a rational target for treatment with chemotherapeutic agents. Van der Heijden et al. have demonstrated that pancreatic cancer cells having defects in Fanconi anemia and BRCA2 pathway are remarkably sensitive to mitomycin-C both in culture and mice [7, 8]. Isacoff et al. reported good results with mitomycin-C plus fluorouracil regimen in first-line therapy of locally advanced pancreatic cancer, with two out of 50 patients achieving complete remission [9]. Another study using the same regimen in patients with metastatic pancreatic carcinoma also showed some activity including one complete remission [10].

    Purpose: The purpose of this study was to evaluate local transarterial chemoperfusion (TACP) in locally recurrent pancreatic carcinoma and advanced tumor stages which did not respond to prior systemic chemotherapy. The tumor response, survival, and pain response were retrospectively analyzed. Materials and method: Forty outpatients (median age 62 years, range 36 - 79) were treated with a minimum of 3 (mean 6, range 3 - 12) applications per patient in four-week intervals. Twenty-eight patients were in advanced tumor stages, and 12 patients had locally recurrent tumors. Gemcitabine (1,000 mg/m{sup 2}) and mitomycin C (8.5 mg/m{sup 2}) were administered within 1 hour through a celiac trunk catheter. The tumor response (diameter, volume) was measured using MRI or CT and classified according to RECIST. The pain response was defined as a reduction of pain intensity of more than 50% on a visual analog scale, or a reduction of more than 50% in analgesics consumption, or a switch to a less potent analgesic agent. Results: The treatment was tolerated well by all patients. No clinically relevant problems or grade III or IV toxicity according to CTC (Common Toxicity Criteria) were observed. Tumor-related pain was relieved in 20/32 (62.5%) cases. Radiologically, 'complete response' was found in 3/40 (7.5%), 'partial response' in 9/40 (22.5%), 'stable disease' in 16/40 (40%), and 'progressive disease' in 12/40 (30%) of the patients. The median survival period since initial diagnosis and first TACP was 16.4 months and 8.1 months, respectively. Locally recurrent tumors showed better, but still not significant results regarding tumor response (41.7% vs. 25%) as well as survival (14.4 vs. 7 months) compared to advanced tumor stages. Responders (CR + PR) showed a significant survival advantage compared to patients with tumor progression (13.0 vs. 6.0 months; p = 0.013). (orig.)

    Full Text Available Context Although surgical resection is the only curative therapeutic option for recurrent or metachronous pancreatic carcinomas, most such cancers are beyond surgical curability. We herein report on two rare cases of remnant pancreatectomy used to treat recurrent or metachronous pancreatic carcinomas. Case reports Case#1 A 65-year-old male developed weight loss and diabetes mellitus 83 months after a pylorus-preserving pancreaticoduodenectomy followed by two years of adjuvant chemotherapy (5- fluorouracil plus leucovorin plus mitomycin C for a pancreatic carcinoma in the head of the pancreas (stage IA. An abdominal CT scan revealed a 3 cm tumor in the remnant pancreas which appeared as a ‘hot’ nodule on FDG-PET. A remnant distal pancreatectomy was performed and a pancreatic carcinoma similar in profile to the primary lesion (stage IIB was confirmed pathologically. Case#2 A 67-year-old male showed increased CA 19-9 levels 25 months after a distal pancreatectomy for a pancreatic carcinoma in the body of the pancreas (stage IA. An abdominal CT scan revealed a cystic lesion in the cut end of the pancreas which appeared as a ‘hot’ nodule on FDG-PET. A remnant proximal pancreatectomy with duodenectomy was performed and a metachronous pancreatic carcinoma (stage III was confirmed pathologically. Conclusion Remnant pancreatectomy can be considered a treatment option for recurrent or metachronous pancreatic carcinomas. FDG-PET can play a key role in detecting remnant pancreatic carcinomas.

  13. A Rare Case of Calf Muscle Metastasis from a Non-Functional Pancreatic Neuroendocrine Carcinoma

    International Nuclear Information System (INIS)

    Pancreatic neuroendocrine tumors (PNET) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. However, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. PNETs can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. Skeletal muscle metastasis is also a rare condition and differentiation between a primary soft tissue sarcoma and metastatic carcinoma is difficult without biopsy. Thus, skeletal muscle metastases from pancreatic neoplasms are exceedingly rare, with only a few cases reported in the literature. We present a 34-year-old man with metastatic pancreatic neuroendocrine carcinoma that was initially thought to be a primary soft tissue tumor. Pathology and immunohistochemistry demonstrated the tumor to be a metastasis from a pancreatic neuroendocrine carcinoma. A brief review of the literature on this subject is also presented

    Full Text Available Malignant tumors of pancreas are usually primary neoplasms and pancreatic metastases are rare findings. We are reporting a case of squamous cell carcinoma (SCC of the esophagus with pancreatic metastasis. A 59-year old woman was admitted with chief complaint of abdominal pain and mass. She was a known case of esophageal SCC since 4 years before when she had undergone transthoracic esophagectomy and cervical esophago-gastrostomy. In order to evaluate recent abdominal mass, CT scan was done which revealed septated cystic lesion in the body and the tail of the pancreas. Palliative resection of the tumor was performed and its histological study showed SCC compatible with her previously diagnosed esophageal cancer.

  15. Interaction of Stellate Cells with Pancreatic Carcinoma Cells

    International Nuclear Information System (INIS)

    Pancreatic cancer is characterized by its late detection, aggressive growth, intense infiltration into adjacent tissue, early metastasis, resistance to chemo- and radiotherapy and a strong “desmoplastic reaction”. The dense stroma surrounding carcinoma cells is composed of fibroblasts, activated stellate cells (myofibroblast-like cells), various inflammatory cells, proliferating vascular structures, collagens and fibronectin. In particular the cellular components of the stroma produce the tumor microenvironment, which plays a critical role in tumor growth, invasion, spreading, metastasis, angiogenesis, inhibition of anoikis, and chemoresistance. Fibroblasts, myofibroblasts and activated stellate cells produce the extracellular matrix components and are thought to interact actively with tumor cells, thereby promoting cancer progression. In this review, we discuss our current understanding of the role of pancreatic stellate cells (PSC) in the desmoplastic response of pancreas cancer and the effects of PSC on tumor progression, metastasis and drug resistance. Finally we present some novel ideas for tumor therapy by interfering with the cancer cell-host interaction

    Currently, chemotherapy is an accredited, standard treatment for unresectable, advanced pancreatic cancer (PC). However, it has been still showed treatment-resistance and followed dismal prognosis in many cases. Therefore, some sort of new, additional treatments are needed for the better therapeutic results for advanced PC. According to the previous reports, it is obvious that interventional endoscopic ultrasonography (EUS) is a well-established, helpful and low-risky procedure in general. As the additional treatments of the conventional therapy for advanced PC, many therapeutic strategies, such as immunotherapies, molecular biological therapies, physiochemical therapies, radioactive therapies, using siRNA, using autophagy have been developing in recent years. Moreover, the efficacy of the other potential therapeutic targets for PC using EUS-fine needle injection, for example, intra-tumoral chemotherapeutic agents (paclitaxel, irinotecan), several ablative energies (radiofrequency ablation and cryothermal treatment, neodymium-doped yttrium aluminum garnet laser, high-intensity focused ultrasound), etc., has already been showed in animal models. Delivering these promising treatments reliably inside tumor, interventional EUS may probably be indispensable existence for the treatment of locally advanced PC in near future. PMID:26677434

    Full Text Available Abstract Background We report the first case of isolated pancreatic lymph node recurrence in a locally advanced breast cancer patient. Case A 41-year old woman underwent radical mastectomy according to Madden and removal of axillary lymph nodes for multicentric infiltrating ductal carcinoma pathologically staged as pT2N2M0. After six years from primary diagnosis, and four years from the diagnosis of lung recurrence, she developed an isolated metastatic lesion to pancreatic lymph node. After surgical excision of metastasis, hormone therapy with Exemestane was begun. At 16 months of follow-up, the patient appears free of disease. Conclusion Because metastatization to visceral organ carries a very unfavorable prognosis, we think that the clinical significance of the elevation of CA 15.3 serum levels in the early detection of recurrence and in monitoring metastatic disease during follow-up, should be not underestimated.

  20. Radiodiagnostics for carcinoma of the pancreas and chronic pancreatitis

    International Nuclear Information System (INIS)

    The purpose of this study is to establish which methods in radiodiagnosis are the most effective in demonstrating the presence of a pancreatic carcinoma or chronic pancreatitis. A second purpose is to evaluate which methods can be used to plan treatment of the patient. The different methods of radiodiagnosis that have been used and are being used to demonstrate disease of the pancreas are described, and their possible applications are reviewed. From this review a scheme is devised for the radiodiagnostic investigation of pancreatic disease. The results of each method of investigation are evaluated for those patients who were investigated in the University Hospital Groningen and compared with those published in the literature. On the basis of the results a final scheme for the diagnostic process is outlined. Ultrasonography and endoscopic pancreaticocholangiography are the prime methods of radiological investigation. Arteriography is an essential method in the assessment of the curative operability. It is established that computerized tomography is of little value after a good ultrasonogram, both for the primary diagnosis and the assessment of the possibility for operative treatment. (Auth.)

  5. The comparative study of tumor angiogenesis and CT enhancement in pancreatic carcinoma

    International Nuclear Information System (INIS)

    Purpose: The purpose of this work was to study the correlation of pancreatic phase Computed tomography (CT) enhancement, intratumoral microvessel density (MVD) and pathologic grades in pancreatic carcinoma and to evaluate the relationship between CT enhancement degree and the malignancy degree of pancreatic carcinoma. Methods: 34 patients with pancreatic carcinoma underwent CT scanning before resection. The enhancement degrees and forms of tumor were observed in pancreatic phase. The operational sample was stained with HE and CD34 marked by immunohistochemistry. MVD and histopathological grades of pancreatic carcinoma were examined. CT enhancement of the tumor, MVD counting in hot spot areas of neoplastic parenchymal cells and pathological grades of pancreatic carcinoma were comparatively analyzed. Result: Highly differentiated pancreatic adenocarcinoma was identified in 16 patients, moderately differentiated tumor in seven and poorly differentiated tumor in 11. Isodensity CT enhancement was demonstrated in 13 cases, slight low density enhancement in nine, slight low density enhancement along with small cyst lesion in nine and slight low density enhancement along with large cyst lesion in three. The counting of MVD with CD34 marked by immunohistochemistry in hot spot areas of neoplastic parenchyma cells were small in ten cases, medium in 16 and large in eight. The pathological grades correlated with CT enhancement of tumor (r=0.7857, P<0.001). The pathological grade correlated with MVD counting of tumor (r=0.3613, P<0.05). The CT enhancement of tumor correlated with MVD (r=0.6768, P<0.001). Conclusion: There was obvious and significant correlation between CT enhancement, pathological grades and MVD numbers in the hot spot areas of tumor. The extent of CT enhancement was inversely proportional to the malignancy degree of pancreatic carcinoma, and inversely proportional to MVD numbers in the hot spot areas of neoplastic parenchyma. The MVD in the hot spot areas of

The study group consisted of 36 patients with pancreatic ductal carcinoma. Tumors were stained using immunohistochemical method (NCL -MMP-9, Novocastra. No correlation was found between tumor MMP-9 expression and age, gender or grade of histological malignancy. However, statistical analysis revealed a relationship between tumor MMP-9 expression and histological type (adenocarcinoma mucinosum of pancreatic carcinoma. The expression was strongly correlated with lymph node involvement and occurrence of distant metastases (p<0.00001. The results indicate a correlation between the expression of MMP-9 in pancreatic ductal carcinoma and worse prognosis (shown by lymph node involvement and distant metastases.

  7. The CT signs of peripancreatic vascular invasion in pancreatic carcinoma

    International Nuclear Information System (INIS)

    Objective: To analyze various characteristics of multislice spiral CT (MSCT) signs of peripancreatic arterial and venous invasion in pancreatic carcinoma. Methods: In 68 patients with pancreatic carcinoma diagnosed by MSCT, 33 patients were confirmed by surgeco-pathology (12 patients underwent pancreaticoduodenectomy, 21 patients were found that the tumors were unresectable during surgical exploration). The peripancreatic major vessels, including superior mesenteric artery (SMA), celiac artery (CA), hepatic artery (HA), superior mesenteric vein (SMV), and portal vein (PV), were examined carefully by surgeons during the operation. Results: In surgical exploration, 103 of 165 vessels were found uninvolved, and the other 62 vessels were found invaded by the tumors. Except 5 false-negative vessels, the characteristics of invaded peripancreatic major vessels presented in preoperative MSCT were as follows: all of the invaded peripancreatic major arteries were involved by tumors above one-half circumference of the vessel or embedded in tumors. Parts of the invaded peripancreatic major veins, such as 4/17 SMV and 2/13 PV, were involved by tumors below one-half circumference of the vessels, but venous wall irregularity or vascular stenosis or vascular contour alteration appeared at the same time. The invaded peripancreatic major veins, such as 11/17 SMV and 12/13 PV, more often behaved vascular stenosis or obliteration than the invaded peripancreatic arteries including 3/8 CA, 4/7 HA, 4/12 SMA. Irregularity owing to infiltration by tumors appeared more often in the invaded peripancreatic major venous wall (11/17 SMV and 7/13 PV) than in the arterial wall (3/8 CA, 2/7 HA, and 6/12 SMA). Conclusion: The CT signs of peripancreatic arterial and venous invasion have different characteristics. (authors)

    Prognosis of pancreatic carcinoma in 28 Hiroshima A-bomb survivors was compared with that in background- and tumor size-matched non-exposed patients living in Hiroshima. A-bomb survivors consisted of 13 exposed within 2,000 m from the hypocenter, 12 who had entered the city within 3 days after A-bombing, and 3 not clarified in detail. Survival time was significantly prolonged when tumor resection or surgical internal fistula for obstructive jaundice was performed. The significant therapeutic factor was thus adjusted by using the Cox model to clarify the difference in cumulative survival rates between the exposed and non-exposed groups of pancreatic cancer patients. Median survival was 120 days in the exposed group and 186 days in the non-exposed group. The corresponding figures for 75% and 25% cumulative survival rates were 175 days and 75 days in the exposed group and 238 days and 120 days in the non-exposed group. Prognosis was worse in the exposed group than the non-exposed group. (N.K.).

  9. Circulating endothelial cells and other angiogenesis factors in pancreatic carcinoma patients receiving gemcitabine chemotherapy

    International Nuclear Information System (INIS)

    Pancreatic carcinoma is a significant cause of cancer-related death in developed countries. As the level of circulating endothelial cells (CECs) is known to increase in response to various cancers, we investigated the predictive potential of CEC levels and the association of these levels with the expression of proangiogenic factors in pancreatic carcinoma patients. Pancreatic carcinoma patients receiving gemcitabine chemotherapy were prospectively assigned to this study. CEC levels were measured using the CellTracks system, and the plasma levels of several angiogenesis factors were measured using multiplex immunoassay. Associations between clinical outcomes and the levels of these factors were evaluated. Baseline CEC levels were markedly higher in pancreatic carcinoma patients (n = 37) than in healthy volunteers (n = 53). Moreover, these high CEC levels were associated with decreased overall survival (median, 297 days versus 143 days, P < 0.001) and progression-free survival (median, 150 days versus 64 days, P = 0.008), as well as with high vascular endothelial growth factor, interleukin (IL)-8, and IL-10 expression in the pancreatic carcinoma patients. Several chemokines and proangiogenic factors correlate with the release of CECs, and the number of CECs detected may be a useful prognostic marker in pancreatic carcinoma patients undergoing gemcitabine chemotherapy.

    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.

    Background Several previous studies have shown that diffusion-weighted imaging (DWI) can provide additional information for focal pancreatic lesions by demonstrating more restricted diffusion in solid malignant tumors than in chronic pancreatitis,which can be indicated by a decreased apparent diffusion coefficient (ADC).However,these studies have a modest sample size and convey inconclusive results.The aim of this study was to determine,in a meta-analysis,the diagnostic performance of quantitative diffusion-weighted magnetic resonance imaging in distinguishing pancreatic carcinoma from mass-forming chronic pancreatitis.Methods We determined the sensitivities and specificities across studies.A summary receiver operator characteristic (sROC) curve was constructed to calculate the area under the curve (AUC).Results The pooled sensitivity of DWI was 0.86 (95% CI:0.80-0.91) and the pooled specificity was 0.82 (95% CI:0.72-0.89).The AUC of the sROC was 0.91 (95% CI:0.88-0.93).Conclusions DWI may be a potentially technically feasible tool for differentiating pancreatic carcinoma from massforming chronic pancreatitis.However,large-scale randomized control trials are necessary to assess its clinical value.

  13. The effect of irradiation and chemotherapeutic agents on a new pancreatic carcinoma cell line

    International Nuclear Information System (INIS)

    Full text: In vitro studies using pancreatic cancer cells are based mostly on a few well-characterized cell lines, which have been established in culture for up to 20 years. The phenotype of these cell lines can change in long-term cultures and, due to extensive sub-cloning, they occasionally show phenotypic and genotypic instability, with eventual loss of the characteristics of the tumors from which they were originated. Therefore, we have established and characterized a new pancreatic cancer cell line from pleural effusion of a patient with advanced cancer of pancreas, designated p34, and evaluated its radio-chemo sensitivity. The cells were characterized using usual microscopy, FACS analysis, immunohistochemistry and cytogenetics. Cell survival following irradiation or drug treatment was measured by colorimetric XTT assay. Results. The p34 cells showed typical morphological characteristics of epithelial pancreatic tumor cells and expressed cytokeratin 7 and pancreatic antigen but were negative for vimentin. The line consisted of hyperdiploid cells with a modal number of 48 including trisomy of chromosomes 2, 5 and 7, monosomy of chromosome 20 and two marker chromosomes: 2p- and iso(8q). The same chromosomal changes were present in early and late passages (during >1 year of cultivation). Irradiation decreased significantly the p34 cell survival with the LD50 = 4,5 Gy. Gemcitabine, taxol and vinorelbine significantly inhibited cell proliferation in nM concentrations, whereas cis-platin was effective in μM concentrations. The p34 cell line may serve as a new model for studying various aspects of both biology and anticancer treatment in carcinoma of the pancreas

  14. An evaluation of spiral CT scan in diagnosis of unresectable pancreatic carcinoma

    International Nuclear Information System (INIS)

    Objective: To investigate the spiral CT findings and diagnostic criteria of unresectable pancreatic carcinoma. Methods: The spiral CT findings of 17 cases of pancreatic carcinoma, confirmed by surgery and histo-pathologic examinations, were retrospectively studied. Factors like peripancreatic vasculars and fat tissue, metastases or adjacent involvement, and the protocol of the scan were carefully evaluated. Results: The CT manifestations of unresectable pancreatic carcinoma included: peripancreatic vascular involvement, metastasis found liver and peritoneum, adjacent organ involvement, distant metastatic lymphadenopathy and invasion of peripancreatic fat plane accompanied with other signs of unresectable lesion revealed in the same evaluation. Conclusion: Spiral CT scan accurately evaluates the range, degree of tumor, metastatic lesions and especially the peripancreatic vascular involvement. Spiral CT scan is a valuable in determining the resectability of pancreatic cancer

    In the past, chronic pancreatitis has been regarded as a fairly uniform and largely untreatable disorder that most commonly affects patients who both lack gainful employment or adequate insurance coverage and have a tendency to smoke and drink. Large clinical trials suggest that this perception is not only misguided and discriminatory but also not based on facts. We forgot that the perception of chronic liver disease was similar before World War II, and just like liver cirrhosis the fibrosis and cirrhosis of the pancreas--i.e. chronic pancreatitis--is the end result of a range of environmental, inflammatory, infectious and genetic disorders. A growing number of these have only recently been recognized as a distinct entity and several of which are becoming truly treatable. A large proportion of the risk for developing pancreatitis is conveyed by genetic risk factors, and we estimate that less than half of those have been identified so far. The same holds true for protective factors that can prevent pancreatitis, even in the face of excessive alcohol abuse. Various gene mutations and polymorphisms appear to determine an individual's susceptibility for developing pancreatic disease, for the severity of the disease, and for the disease progression. The spectrum of genotype/phenotype associations ranges from straightforward autosomal dominant traits with near-complete penetrance, as for the most common mutations in the cationic trypsinogen gene (PRSS1), to moderate risks factors without mendelian inheritance patterns, as for SPINK1 and CFTR mutations, to very subtle risk associations and disease modifiers that can only be identified in large cohort studies, as for the chymotrypsin C, calcium-sensing receptor and the anionic trypsin (PRSS2) mutations. Only a better understanding of the disease mechanisms that underlie these changes will make an individualized therapy of pancreatic disorders a realistic option. PMID:20814206

    Endoscopic drainage is the first-line therapy in the management of pancreatic pseudocysts. Before endoscopic drainage, clinicians should exclude the presence of pancreatic cystic neoplasms and avoid drainage of immature peripancreatic fluid collections or pseudoaneurysms. The indication for endoscopic drainage is not dependent on absolute cyst size alone, but on the presence of attributable signs or symptoms. Endoscopic management should be performed as part of a multidisciplinary approach in close cooperation with surgeons and interventional radiologists. Drainage may be performed either via a transpapillary approach or a transmural approach; additionally, endoscopic necrosectomy may be performed for patients with walled-off necrosis. PMID:26895678

    2007-01-01

    Objective To study the expressions of MMP-2 and TIMP-2 in pancreatic carcinoma and their relationship with tumor invasion, local metastasis and prognosis of the carcinoma. Methods The expressions of MMP-2 and TIMP-2 were examined in 32 patients with pancreatic carcinomas by S-P immunohistochemical technique and the correlation with pathological tumor parameters were analyzed. Survival analysis was made by using the Kaplan-Meier method. Results The positive rates of MMP-2, TIMP-2 in 32 patients with pancreatic carcinoma were 56.25% and 75.00%, which were significantly higher than those of the controls(P<0.05). Expressions of MMP-2 and TIMP-2 were independent of sex, age, histological grading and type, but well correlated with the lymph node metastasis and TNM clinical staging(Ⅰ and Ⅲ, Ⅱ and Ⅲ). There was a significant association between MMP-2, TIMP-2 and prognosis in pancreatic carcinoma. Conclusion MMP-2 and TIMP-2 might be useful markers for biological aggressiveness of this malignancy and might contribute to the invasive properties of pancreatic carcinoma, which can be used to evaluate the prognosis of patients.

  18. Transarterial infusion chemotherapy combined with high intensity focused ultrasound for the treatment of pancreatic carcinomas: a clinical study

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of transarterial infusion chemotherapy combined with high intensity focused ultrasound (HIFU) for the treatment of pancreatic carcinomas. Methods: A total of 64 patients with inoperable pancreatic carcinomas were randomly divided into study group (n=32) and control group (n=32). Transarterial infusion chemotherapy combined with HIFU was employed in patients of study group, while simple transarterial infusion chemotherapy was conducted in patients of control group. The effective rate, the clinical benefit rate (CBR), the occurrence of side effect and the survival time of the two groups were recorded. The results were compared between the two groups. Results: The effective rate (PR + MR), the median survival time and the one-year survival rate of the study group were 55.56%, 13.0 months and 68.75% respectively, while the effective rate (PR + MR), the median survival time and the one-year survival rate of the control group were 28.57%, 9.0 months and 43.75% respectively. Both the effective rate and the one-year survival rate of the study group were significantly higher than those of the control group (P<0.05). Conclusion: Compared with pure transarterial infusion chemotherapy, transarterial infusion chemotherapy combined with HIFU can significantly improve the short-term efficacy and increase the one-year survival rate for patients with advanced pancreatic carcinomas.

  20. Radiation therapy for advanced laryngeal carcinoma

    International Nuclear Information System (INIS)

    From 1967 through 1985, 92 patients with T3 and T4 laryngeal carcinoma were treated with radiation at Osaka University Hospital. Of 92 patients, patients with 14 T3 and 29 T4 carcinoma were treated with a total dose of 60 Gy or more, and those with 14 T3 and 21 T4 carcinoma were treated with a total dose of 40 to 58 Gy and followed by total laryngectomy. Other 14 patients were palliatively treated with a total dose less than 60 Gy without surgery. The 5-year local control rates for T3 and T4 carcinoma treated with radical radiation were 48% and 24%, respectively. The 5-year cause-specific survival rates for T3 carcinoma treated with radical and preoperative radiotherapy were 48% and 71%, and corresponding figures for T4 carcinoma were 52% and 43%. There were no statistically significant differences between cause-specific survival rates of radical and preoperative groups. The 5-year cause-specific survival rates for T3N0 and T4N0 cases treated with radical radiation were 83% and 56%, and corresponding figures for T3N+ and T4N+ cases were 13% and 45%. Voice preservation rates of T3 and T4 patients treated with radical radiation were about 1/2 and 1/4, respectively. Considering the QOL of patients, radiotherapy for advanced carcinoma of larynx should be considered as a primary treatment especially for N0 cases. (author)

  1. Radiotherapy Technical Considerations in the Management of Locally Advanced Pancreatic Cancer: American-French Consensus Recommendations

    International Nuclear Information System (INIS)

    Summary: Pancreatic carcinoma is a leading cause of cancer-related mortality. Approximately 30% of pancreatic cancer patients present with locally advanced, unresectable nonmetastatic disease. For these patients, two therapeutic options exist: systemic chemotherapy or chemoradiotherapy. Within this context, the optimal technique for pancreatic irradiation is not clearly defined. A search to identify relevant studies was undertaken using the Medline database. All Phase III randomized trials evaluating the modalities of radiotherapy in locally advanced pancreatic cancer were included, as were some noncontrolled Phase II and retrospective studies. An expert panel convened with members of the Radiation Therapy Oncology Group and GERCOR cooperative groups to review identified studies and prepare the guidelines. Each member of the working group independently evaluated five endpoints: total dose, target volume definition, radiotherapy planning technique, dose constraints to organs at risk, and quality assurance. Based on this analysis of the literature, we recommend either three-dimensional conformal radiation therapy or intensity-modulated radiation therapy to a total dose of 50 to 54 Gy at 1.8 to 2 Gy per fraction. We propose gross tumor volume identification to be followed by an expansion of 1.5 to 2 cm anteriorly, posteriorly, and laterally, and 2 to 3 cm craniocaudally to generate the planning target volume. The craniocaudal margins can be reduced with the use of respiratory gating. Organs at risk are liver, kidneys, spinal cord, stomach, and small bowel. Stereotactic body radiation therapy should not be used for pancreatic cancer outside of clinical trials. Radiotherapy quality assurance is mandatory in clinical trials. These consensus recommendations are proposed for use in the development of future trials testing new chemotherapy combinations with radiotherapy. Not all of these recommendations will be appropriate for trials testing radiotherapy dose or dose

    Pancreatic adenocarcinoma ranks as the fourth most common cause of cancer death in the USA. Patients usually present late with advanced disease, limiting attempted curative surgery to 10% of cases. Overall prognosis is poor with one-year survival rates of less than 10% with palliative chemotherapy and/or radiotherapy. Given these dismal results, a minimally invasive treatment capable of local destruction of tumor tissue with low morbidity may have a place in the treatment of this disease. In this paper we review the preclinical photodynamic therapy (PDT) studies which have shown that it is possible to achieve a zone of necrosis in normal pancreas and implanted tumour tissue. Side effects of treatment and evidence of a potential survival advantage are discussed. We describe the only published clinical study of pancreatic interstitial PDT, which was carried out by our group (Bown et al Gut 2002), in 16 patients with unresectable locally advanced pancreatic adenocarcinoma. All patients had evidence of tumor necrosis on follow-up imaging, with a median survival from diagnosis of 12.5 months. Finally, we outline a phase I dose-escalation study of verteporfin single fibre PDT followed by standard gemcitabine chemotherapy which our group is currently undertaking in patients with locally advanced pancreatic cancer. Randomized controlled studies are also planned.

    Full Text Available Context Undifferentiated (spindle cell carcinomas of the pancreas are rare anaplastic variants of pancreatic ductal adenocarcinoma with a frequency of 2% of pancreatic exocrine tumors. Their clinicopathological features are limited and obtained by few previously case reports. We report a case of undifferentiated pancreatic carcinoma with a rare focal osteochondroid differentiation. Case report A sixty-six-year-old woman was admitted to our hospital for abdominal pain and nonspecific nausea for almost 40 days. Imaging studies revealed a well-defined cystic–solid mass with heterogeneous density involving the tail of the pancreas. We performed an en bloc distal pancreatectomy with splenectomy for radical excision, as well as regional lymphadenectomy. The resected specimen revealed a 4.0×5.0 cm exophytic clear-bordered neoplasm of the tail of the pancreas containing necrotic and calcified areas, without splenic invasion. The lymph node involvement was not detected (0/5 and the surgical margins were negative. Microscopy showed pleomorphism with giantcells, spindle-shaped cells with anaplasia, and osteochondroid differentiation. A diagnosis of undifferentiated (spindle cell carcinoma of the pancreas with focal osteochondroid differentiation was made. The patient declined chemotherapy and extended lymphadenectomy. She suffered from liver and lymph nodes metastasis 9 months after surgery, and she subsequently died 4 months later due to high tumor burden. Conclusions Undifferentiated pancreatic carcinoma with osteochondroid differentiation is rare but associated with extremely poor prognosis. It should be included in the differential diagnosis of pancreatic mass lesions.

    AIM: To evaluate the use of three-dimensional imaging of pancreatic carcinoma using multidetector computed tomography (CT) in a prospective study. METHODS: Ten patients with suspected pancreatic tumors were examined prospectively using multidetector CT (Somatom Sensation 16, Siemens, Erlangen, Germany). The images were evaluated for the presence of a pancreatic carcinoma and invasion of the peripancreatic vessels and surrounding organs. Using the isotropic CT data sets, a three-dimensional image was created with automatic vascular analysis and semiautomatic segmentation of the organs and pancreatic tumor by a radiologist. The CT examinations and the three-dimensional images were presented to the surgeon directly before and during the patient's operation using the Medical Imaging Interaction Toolkit-based software "ReLiver". Immediately after surgery, the value of the two images was judged by the surgeon. The operation and the histological results served as the gold standard. RESULTS: Nine patients had a pancreatic carcinoma (all pT3), and one patient had a serous cystadenoma. One tumor infiltrated the superior mesenteric vein. The infiltration was correctly evaluated. All carcinomas were resectable. In comparison to the CT image with axial and coronal reconstructions, the three-dimensional image was judged by the surgeons as better for operation planning and consistently described as useful. CONCLUSION: A 3D-image of the pancreas represents an invaluable aid to the surgeon. However, the 3D-software must be further developed in order to be integrated into daily clinical routine.

    BACKGROUND: Pancreatic cancer remains a devastating disease with a 5-year survival rate of less than 5%. Recent advances in diagnostic methods and therapeutic approaches have increased the possibility of improving the existing poor prognosis. DATA  SOURCES: English-language articles reporting early diagnosis and therapy of pancreatic cancer were searched from the MEDLINE and PubMed databases, Chinese-language articleswerefromCHKD(ChinaHospitalKnowledgeDatabase). RESULT: The current literature about pancreatic cancer was reviewed from three aspects: statistics, screening and early detection, and therapy. CONCLUSIONS: Early detection and screening of pancreatic cancer currently should be limited to high risk patients. Surgical resection is the only curative approach available, with some recent improvement in outcomes. Gemcitabine has been a standard treatment during the last decade. Gemcitabine-based combination treatment, especially combined with newer molecular targeted agents, is promising. The rationale for radiotherapy is controversial, but with the recent development of modern radiation delivery techniques, radiotherapy should be intensified. Patients with borderline pancreatic cancer could benefit from neoadjuvant therapy but more evidence is needed and the best neoadjuvant regimen is still to be determined.

    2014-09-01

    Full Text Available Context Autoimmune pancreatitis is classified into two distinct clinical profiles. Care report Type 1 autoimmunepancreatitis (AIP is considered to be a manifestation of a novel clinicopathological entity called IgG4 related sclerosingdisease, diagnosed using the Mayo Clinic HISORt criteria. Extra-pancreatic manifestations can include involvement of bileducts, salivary gland, lung nodules, thyroiditis, tubulointerstitial nephritis, renal masses, and retroperitoneal fibrosis. Type2 autoimmune pancreatitis on the other hand is confirmed by histologically seen duct centric pancreatitis without elevationof IgG4 or involvement of other organs. In type 1 autoimmune pancreatitis, extrapancreatic manifestations like bile ductstrictures, tubulointerstitial nephritis, renal nodules, retroperitoneal fibrosis respond to steroid therapy. Conclusion Wepresent a case of type 1 autoimmune pancreatitis in which the renal mass did not respond to steroid therapy and was later on found to be renal cell carcinoma. To the best of our knowledge this is only the third reported case of autoimmune pancreatitis in which the patient had renal cell carcinoma. Our case highlights the importance of close follow up of lesions that do not respond to steroid treatment which in this case proved to be renal cell cancer.

The snap-frozen or RNA-later preserved samples of 18 pancreatic adenocarcinomas, 5 chronic pancreatitis cases and 6 specimens of grossly normal pancreas were used for microarray analysis by HG-U133 Plus 2.0 oligonucleotide Affymetrix arrays. Validation was carried out by real-time quantitative PCR (Q-PCR in the set of 66 samples: 31 of pancreatic cancer, 14 of chronic pancreatitis and 21 of macroscopically unchanged pancreas. By Principal Component Analysis of the microarray data we found a very consistent expression pattern of normal samples and a less homogenous one in chronic pancreatitis. By supervised comparison (corrected p-value 0.001 we observed 11094 probesets differentiating between cancer and normal samples, while only seventy six probesets were significant for difference between cancer and chronic pancreatitis. The only gene occurring within the best 10 genes in both comparisons was S100 calcium binding protein P (S100P, already indicated for its utility as pancreatic cancer marker by earlier microarray-based studies. For validation we selected two genes which appeared as valuable candidates for molecular markers of pancreatic cancer: neuroblastoma, suppression of tumorigenicity 1 (NBL1 and anillin (ANLN. By Q-PCR, we confirmed statistically significant differences in these genes with a 9.5 fold-change difference between NBL1 expression in cancer/normal comparison and a relatively modest difference between cancer and pancreatitis. For ANLN even more distinct differences were observed (cancer/normal 19.8-fold, cancer/pancreatitis 4.0-fold. NBL1 and anillin are promising markers for pancreatic carcinoma molecular diagnostics.

  15. Diagnostic value of tissue polypeptide specific antigen in serum for patients with pancreatic carcinoma

    International Nuclear Information System (INIS)

    Objective: To compare the diagnostic value of tissue polypeptide specific antigen (TPS) in serum, with the carbohydrate antigens (CA) 19-9, CA50, CA125 and CA242 in pancreatic carcinoma. Methods: Serum TPS was measured with enzyme linked immunosorbent assay (ELISA). CA19-9 and CA125 were measured with chemiluminescent immunoassay. CAS0 and CA242 were measured with immunoradiometric assay in 33 patients with pancreatitis, 34 patients with pathologically proven pancreatic carcinoma, and 35 patients with non-pancreatic malignancies. Statistic analysis was carried out with SPSS 9.0 software. Results: Patients with pancreatic carcinoma had relatively higher levels of TPS [(386.5 ± 315. 1) U/L] and CA19-9 [(10 820.9 ± 389.7) kU/L] when compared with patients with pancreatitis [(86. 2 ± 28.1) U/L and (61.5 ± 24.7) kU/L, respectively; F = 936. 42, P < 0. 001 ; F = 2217. 09, P < 0. 001], with a sensitivity and a specificity of 70.6% (48/68) and 57.4% (39/68), respectively, for TPS, and 82.4% (28/34) and 77.9% (53/68), respectively, for CA19-9. Diagnostic performance was further improved when TPS was assayed in combination with CA19-9, CA50, CA125 and CA242. Conclusion: Serum TPS has an incremental value in complementing CA19-9 in the diagnosis of pancreatic carcinoma. (authors)

    Bypass surgery for cancer of the pancreatic head is usually done to palliate the obstructive symptoms in the biliary and/or digestive system. However, it is uncommon for patients to require pancreatic duct drainage for recurrent obstructive pancreatitis. In this article, we report a surgical technique of triple bypass consisting of Roux-en-Y hepaticojejunostomy, gastrojejunostomy, and pancreaticojejunostomy for advanced pancreatic cancer. A 76-year-old male patient with locally advanced and metastatic pancreatic head cancer was referred to our department for biliary stricture, duodenal stenosis, and recurrent obstructive pancreatitis associated with persistent pancreatic pseudocyst. In an attempt to resolve all these problems simultaneously, a triple bypass was performed. The patient survived and continued to receive chemotherapy for almost 1 year after surgery without any serious complications. Thus, triple bypass is a useful surgical technique that could relief symptoms and offer better quality of life to patients with advanced pancreatic cancer presenting with biliary stricture, duodenal stenosis, and severe obstructive pancreatitis difficult to treat by medication or endoscopic procedures.

    2005-09-01

    Full Text Available Abstract Background Merkel cell carcinomas are rare neoplasm of neuroendocrine origin, usually observed in elderly people in areas with abundant sunlight, and predominantly located on the head and neck, extremities, and trunk. In many patients, a local recurrence after resection of the primary tumour and even distant metastases can be found. Case presentation We report an unusual occurrence of pancreatic metastases from a previously diagnosed Merkel cell carcinoma with the discovery of a concomitant insulinoma. An 82-year old lady suffered from recurrent attacks of hypoglycemia and presented with an abdominal mass, 2 years prior she had an excision done on her eyebrow that was reported as Merkel cell carcinoma. An extended distal pancreatectomy and splenectomy along with resection of the left flexure of the colon for her abdominal mass was carried out. Final histopathology of the mass was a poorly differentiated endocrine carcinoma in the pancreatic tail, in the peripancreatic tissue and in the surrounding soft tissue consistent with metastatic Merkel cell carcinoma in addition to an insulinoma of the pancreatic body. Conclusion This is the first documented case of a metastatic Merkel cell carcinoma and a concomitant insulinoma, suggesting either a mere coincidence or an unknown neuroendocrine tumor syndrome.

    Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

    About a third of all pancreatic cancer is found to be locally advanced at the time of diagnosis, where the tumor is inoperable but remains localized to the pancreas and regional lymphatics. Sadly, this remains a universally deadly disease with progression to distant disease being the predominant mode of failure and average survival under one year. Optimal treatment of these patients continues to be an area of controversy, with chemotherapy alone being the treatment preference in Europe, and chemotherapy followed by chemoradiation in selected patients, preferred in the USA. The aim of this paper is to summarize the key abstracts presented at the 2013 ASCO Annual Meeting that address evolving approaches to the management of locally advanced pancreatic cancer. The late breaking abstract (#LBA4003) provided additional European data showing non-superiority of chemoradiation compared to chemotherapy in locally advanced pancreatic cancer patients without distant progression following 4 months of chemotherapy. Another late breaking abstract, (#LBA4004), unfortunately showed a promising new complement to gemcitabine and capecitabine using immunotherapy in the form of a T-helper vaccine did not translate to improved survival in the phase III setting.

  3. Defect in assimilation following combined radiation and chemotherapy in patients with locally unresectable pancreatic carcinoma

    International Nuclear Information System (INIS)

    The relative contributions of high-dose irradiation and/or chemotherapy to the nutritional problems of patients with inoperable pancreatic carcinoma were evaluated by study of pancreatic exocrine function and jejunal function and morphologic findings in ten patients before and after treatment. Nutrient assimilation studies included determination of serum carotene levels, D-xylose absorption and fat absorption. Crosby capsule biopsy specimen of jejunal mucosa were evaluated with light microscopy. Fat assimilation was the only parameter of nutritional function to significantly worsen after therapy. Low serum carotene levels present in the patients before therapy remained low but did not significantly change after treatment. D-xylose absorption and the morphologic structure of the jejunal mucosa were normal before and after treatment. These findings support the previous observations that the nutritional problems of the patient with inoperable pancreatic carcinoma are due to pancreatic insufficiency and that high dose irradiation and chemotherapy can exacerbate the pancreatic insufficiency but do not produce jejunal dysfunction. Therefore, it is suggested that pancreatic exocrine replacement therapy may improve the nutritional status of these patients

    Pancreatic carcinoma is the fifth leading cause of cancer-related mortality. The 5-year overall survival is less than 5 %. This very poor prognosis can be explained both by late diagnosis and by treatment resistance, including resistance to radiation therapy. A better understanding of the pancreatic tumorigenesis and knowledge of the most frequent mutations in pancreatic adenocarcinoma (KRAS, p16, TP53, Smad4) open new perspectives for the development of more effective treatments. This review presents the major genetic and molecular alterations in pancreatic cancer that could be targeted to improve radiosensitization. (authors)

  6. Chemoradiation of unresectable pancreatic carcinoma: impact of pretreatment hemoglobin level on patterns of failure

    International Nuclear Information System (INIS)

    Aim: To evaluate, in patients with locally advanced pancreatic carcinoma undergoing concomitant chemoradiation, the impact of pretreatment hemoglobin (Hb) concentration on the outcome in terms of clinical response, local control, metastasis-free survival, disease-free survival, and overall survival. Patients and Methods: 30 patients undergoing concomitant chemoradiation (5-fluorouracil [5-FU], 1,000 mg/m2/day, continuous i.v. infusion days 1-4 of radiotherapy) and external beam radiotherapy (50.4-59.4 Gy) were divided into two groups based on pretreatment median Hb value (11.5 g/dl). The potential prognostic factors examined besides Hb concentration were: tumor site (head vs body-tail), sex (female vs male), cN (cN0 vs cN1), dose of external beam radiotherapy (50.4 Gy vs 59.4 Gy), presence of jaundice at diagnosis (yes vs no), weight loss at diagnosis (≥ 5 kg vs 11.5 g/dl. Metastasis-free survival was 5.1 months in patients with an Hb ≤ 11.5 g/dl and 10.7 months in patients with an Hb > 11.5 g/dl (p = 0.010). Median actuarial disease-free survival was 5.1 and 10.2 months in patients with an Hb ≤ 11.5 and > 11.5 g/dl, respectively (p = 0.026). Median actuarial overall survival was 7.5 and 10.3 months in patients with an Hb ≤ 11.5 and > 11.5 g/dl, respectively (p = 0.039). On multivariate analysis, Hb concentration at diagnosis was the only factor prognostically correlated with metastasis-free survival (p = 0.026), disease-free survival (p = 0.032), and overall survival (p = 0.048). Conclusion: In a group of patients with locally advanced pancreatic carcinoma treated with chemoradiation, a significant correlation was observed between pretreatment Hb levels and metastasis-free survival, disease-free survival, and overall survival.

  7. Using Multidetector Row Computed Tomography to Diagnose and Stage Pancreatic Carcinoma: the Problems and the Possibilities

    2005-01-01

    Full Text Available The sensitivity of computed tomography (CT in the diagnosis of pancreatic neoplasms and accurate tumor staging has significantly been improved by the use of thin-section multi-detector row CT techniques. Greater table speed, improved tube cooling, high resolution imaging and the possibility of isotropic voxels have led to optimal multiplanar reconstruction in any arbitrary plane and particularly along the pancreatic duct and peripancreatic vessels, significantly improving the detection of small pancreatic tumors and surgical resectability where imaging modalities have so far yielded disappointing results. Nonetheless, while multi-detector row CT has greatly enhanced the imaging capabilities of CT, early diagnosis is practically impossible to achieve, since the tumor remains asymptomatic until the surrounding structures are involved. Furthermore, even when treated with radical surgery, the incidence of recurrence is high and the prognosis of pancreatic carcinoma still remains extremely poor and has not changed over the past years. In this article, the recent technical developments of multi-detector row CT in diagnosing pancreatic neoplasms and staging are considered, with special emphasis on multi-detector row CT angiography techniques and curved planar reformations. Some remaining challenging problems such as the pre-operative identification and characterization of small hepatic lesions and detection of omental and peritoneal metastasis, the diagnosis of small isoattenuating pancreatic adenocarcinomas and promising strategies to differentiate between pancreatic adenocarcinoma and chronic inflammatory changes are also presented.

    AIM: To directly investigate the relationship between telomerase activity and its subunit expression and the inhibitory effect of antisense hTR on pancreatic carcinogenesis.METHODS: We examined the telomerase activity and its subunit expression by cell culture, polymerase chain reaction (PCR), PCR-silver staining, PCR-ELISA, DNA sequencing, MTT and flow cytometry methods.RESULTS: PCR-silver staining and PCR-ELISA methods had the same specificity and sensitivity as the TRAP method.Telomerase activity was detected in the extract of the 10th,20th and 30th passages of P3 cells,while it was absent in fibroblasts. Furthermore, after the 30th generation, the proliferation period of fibroblast cells was significantly prolonged. Telomerase activity and hTERTmRNA were detected in two pancreatic carcinoma cell lines, but were found to be negative in human fibroblast cells. Telomerase activity and hTERTmRNA were tested in pancreatic carcinoma specimens of 24 cases. The telomerase activity was positive in 21 of the 24 cases (87.5 %), and the hTERTmRNA in 20 cases (83.3 %). In adjacent normal tissues positive rates were both 12.5 %. There was a significant difference between the two groups. This indicated a significant correlation between the expression level of telomerase activity and histologic differentiation,metastasis and advanced clinical stage of pancreatic carcinoma. Our findings showed that the expressions of hTR and TP1mRNA were not correlated with the activity of telomerase but the expression of hTERTmRNA was. After treatment with PS-ODNs, telomerase activity in P3 cells weakened and the inhibiting effect became stronger with an increase in PS-ODNs concentration. There was a significant difference between different PS-ODN groups (P<0.05). Inhibition of telomerase activity occurred most significant with PS-ODN1.The results of the FCM test of pancreatic cancer P3 cells showed an increase in the apoptotic rate with increasing PS-ODN1 and PS-ODN2concentrations

  9. Comparison of the diagnostic accuracy of ultrasound, computer tomography and ERPC in chronic pancreatitis and carcinoma of the pancreas

    A comparison of the diagnostic accuracy of ultrasound, computer tomography and ERPC in chronic or recurrent pancreatitis and pancreatic carcinoma has shown that ERPC is the most precise of the three methods. This was particularly important in the demonstration of the small, still operable, carcinomas of the pancreas. Sonography is most useful for serial observations of pancreatic pseudocyste due to chronic recurrent pancreatitis. In this situation, ERPC should only be used if sonography and computer tomography cannot localise the lesion. Where the computer tomogram has shown evidence of enlargement of the pancreas, sonography may show an area devoid of echoes within the enlarged organ, suggesting the presence of a carcinoma. Computer tomography is superior to ultrasonography in delineating the extent of extensive pancreatic disease and in showing the anatomical structures surrounding the pancreas.

    The aim of this study was to evaluate the safety of irreversible electroporation (IRE) and the outcome of patients undergoing IRE of locally advanced pancreatic cancer (PC). Twenty-one patients with unresectable PC underwent open (n=19) or percutaneous (n=2) IRE of the tumor using the Nanoknife system with two electrodes that were repositioned several times to affect the whole mass. The size of the tumor was 39±10mm with a range from 21 to 65mm. Five patients underwent neoadjuvant chemotherapy and seven patients were treated with chemotherapy after IRE. Complications occurred in five patients, which resulted in prolongation of the average hospital stay from 10 to 34 days. There was no mortality in the first postoperative month. Median survival after IRE was 10.2 months compared to 9.3 months in a matched cohort (hazard ratio = .54, p = .053). The quality of life was declining slowly. 81% of time after IRE the Karnofsky performance status was ≥70 and sharp decline occurred approximately 8 weeks before death.In conclusion, IRE is a safe palliative treatment option for a percentage of patients with locally advanced pancreatic carcinoma. The patients treated with open IRE lived a decent life until 8 weeks before their death. We believe that IRE of pancreatic carcinoma can be regarded as an option, if imaging or explorative laparotomy show that R0 resection in not possible. PMID:26774149

    International Nuclear Information System (INIS)

    Preoperative chemoradiotherapy in combination with radiation of 30 Gy and chemotherapy with oral uracil-tegafur for 14 patients with advanced lower rectal carcinoma was performed. Tumors were located at RaRb in 5 cases, RbRa in 2, Rb in 3, and RbP in 4 with a mean diameter of 3.8 cm. Preoperative lymphnodes were diagnosed as cN0 in 8 cases, cN1 (metastases of perirectal nodes) in 4, cN1 (perirectal and along superior rectal artery nodes) in 1, and cN3 (perirectal and lateral nodes) in 1. Efficacy for primary carcinomas was evaluated as Partial Response in 9 cases, Stable Disease in 5 and perirectal nodes were down-sized in 4 without down-sizing of either along superior rectal artery nodes or lateral nodes. Margins of primary carcinomas to anal verge were prolonged in 7 cases with a mean prolongation of 0.81 cm. Autonomic nerve-preserving resections with lymphadenectomy of perirectal and along superior rectal artery nodes were performed. Histopathologically efficacy for primary tumors was diagnosed to as not effective in 9 cases, partially effective in 5, and all lymphnodes were combined with necroses and fibrosis. Preoperative chemoradiotherapy is safe for preserving autonomic nerves and serves to preserve the sphincter. A forthcoming study with more appropriate radiation, chemotherapy and lymphadenectomy is being considered. (author)

    Full Text Available Abstract Castleman disease (CD is an uncommon benign lymphoproliferative disorder, which usually presents as solitary or multiple masses in the mediastinum. Peripancreatic CD was rarely reported. Herein, we report two cases of unicentric peripancreatic CD from our center. A 43-year-old man and a 58-year-old woman were detected to have a pancreatic mass in the routine medical examinations. Both of them were asymptomatic. The computed tomography and ultrasonographic examination revealed a mild enhancing solitary mass at the pancreatic head/neck. No definite preoperative diagnosis was established and Whipple operations were originally planned. The intraoperative frozen section diagnosis of both patients revealed lymphoproliferation. Then the local excisions of mass were performed. Histological examination revealed features of CD of hyaline-vascular type. No recurrence was found during the follow-up period. CD should be included in the differential diagnosis of pancreatic tumors. Local excision is a suitable surgical choice.

  17. Neoadjuvant chemoradiation with Gemcitabine for locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    To evaluate efficacy and secondary resectability in patients with locally advanced pancreatic cancer (LAPC) treated with neoadjuvant chemoradiotherapy (CRT). A total of 215 patients with locally advanced pancreatic cancer were treated with chemoradiation at a single institution. Radiotherapy was delivered with a median dose of 52.2 Gy in single fractions of 1.8 Gy. Chemotherapy was applied concomitantly as gemcitabine (GEM) at a dose of 300 mg/m2 weekly, followed by adjuvant cycles of full-dose GEM (1000 mg/m2). After neoadjuvant CRT restaging was done to evaluate secondary resectability. Overall and disease-free survival were calculated and prognostic factors were estimated. After CRT a total of 26% of all patients with primary unresectable LAPC were chosen to undergo secondary resection. Tumour free resection margins could be achieved in 39.2% (R0-resection), R1-resections were seen in 41.2%, residual macroscopic tumour in 11.8% (R2) and in 7.8% resection were classified as Rx. Patients with complete resection after CRT showed a significantly increased median overall survival (OS) with 22.1 compared to 11.9 months in non-resected patients. Median OS and disease-free survival (DFS) of all patients were 12.3 and 8.1 months respectively. In most cases the first site of disease progression was systemic with hepatic (52%) and peritoneal (36%) metastases. A high percentage of patients with locally advanced pancreatic cancer can undergo secondary resection after gemcitabine-based chemoradiation and has a relative long-term prognosis after complete resection

    Full Text Available Pancreatic cancer still remains a significant, unresolved therapeutic challenge and is the most lethal type of gastrointestinal cancer with a 5-year survival rate of 5%. Adjuvant chemotherapy remains to be gemcitabine alone, though fluorouracil offers the same survival and role of radiation remains controversial. Nevertheless, only a few patients survive for at least 5 years after R0 resection and adjuvant therapy. Borderline resectable pancreatic cancer remains an area that requires multi-disciplinary approach. Neoadjuvant therapy very likely plays a role to downstage to a resectable state in these subgroup patients. There are different treatment approaches to locally advanced pancreatic cancer management, including single or multi-agent chemotherapy, chemotherapy followed by chemoradiation, or immediate concurrent chemoradiation. Most patients need palliative treatment. Once pancreatic cancer becomes metastatic, it is uniformly fatal with an overall survival of generally 6 months from time of diagnosis. Gemcitabine has been the standard since 1997. FOLFIRINOX (5-fluorouracil, oxaliplatin, irinotecan, leucovorin has already shown superiority over gemcitabine in both progression-free survival and overall survival, but this regimen is suitable only for selected patients in ECOG performance status 0-1. FOLFIRINOX has already trickled down to the clinic in various modifications and in different patient groups, both locally advanced and metastatic. Many targeted agents, including bevacizumab, cetuximab showed negative results, except mild benefit with addition of erlotinib with gemcitabine, which was not considered clinically significant. There is no consensus regarding treatment in the second-line setting. It will be true to say that there was a real medical breakthrough with regards to improving the prognosis of pancreatic cancer as of 2013 with the results of MPACT study. In this study, patients whoreceived nab-paclitaxel plus gemcitabine lived a

  19. Safety and efficacy of enzyme targeting intraoperative radiosensitization therapy (KORTUC-IORT) for advanced pancreatic cancer

    International Nuclear Information System (INIS)

    We developed a new radiosensitizer injection containing hydrogen peroxide and sodium hyaluronate just followed by intraoperative radiotherapy (IORT) for locally advanced pancreatic cancer, named KORTUC-IORT (Kochi Oxydol-Radiation Therapy for Unresectable Carcinoma + IORT). Fourteen patients were treated with KORTUC-IORT, external beam radiotherapy (EBRT), and systemic chemotherapy. With KORTUC-IORT, the agent containing hydrogen peroxide and sodium hyaluronate, was injected into tumor tissue just prior to administration of IORT under ultrasonic guidance. All treatments related with KORTUC-IORT were well tolerated, with few adverse effects. One year survival rate is 67% and median survival period is 15 months. The present formulation can be delivered safely and effectively under the conditions used. (author)

    Full Text Available Context Renal cell carcinoma has shown less response to systemic therapies including chemotherapy, radiotherapy andimmunotherapy than other cancers. Metastasis of renal cell carcinoma to the pancreas occurs, even after long term radicalnephrectomy, surgical resection remains the only potentially curative intervention. We performed surgery for pancreatic metastatic renal cell carcinoma and analyzed the results. Methods We retrospectively analyzed 11 patients who had undergone pancreatic resection or metastasectomy at our hospital from January 1994 to January 2010. Patient’s demographics, clinical variables, types of pancreatic resections (standard or atypical resection, primary histopathology, surgical outcomes, survival and disease free interval were examined. We compared the standard pancreatic resection to atypical resection (enucleation or enucleo-resection. Results Eleven patients underwent 14 pancreatic resections or metastasectomy (3 pancreaticoduodenectomy, 4 distal pancreatectomy, 1 completion of pancreatectomy, 4 enucleations and two enucleo-resections for pancreatic renal cell carcinoma metastasis. The median age was 73 years, the median time period between nephrectomy and finding of pancreatic metastasis was 11.4 years. One patient showed synchronous pancreatic metastatic lesions on radiology. One patient died from a splenic artery pseudoaneurysm rupture 35 days after the surgery. Major complications occurred in 4 patients with standard resection (one hemoperitoneum, three pancreatic fistulas, and in one patient with atypical resection (duodenal fistula; six patients with standard resection presented postoperative diabetes mellitus. Median survival age was 6.5 years (range 1-9 years. Two patients died of metastatic disease 5 to 6years, while 7 patients are alive and well 1 to 9 years after surgery. Conclusions According to these results and regardless of the small number of cases, atypical resection of metastatic renal cell

    To evaluate the utility of multiphase contrast-enhanced computed tomography (CT) findings alone and in combination for differentiating focal-type autoimmune pancreatitis (f-AIP) from pancreatic carcinoma (PC). The study group comprised 22 f-AIP lesions and 61 PC lesions. Two radiologists independently evaluated CT findings. Frequencies of findings were compared between f-AIP and PC. Statistical, univariate and multivariate analyses were performed. Homogeneous enhancement during the portal phase (AIP, 59 % vs. PC, 3 %; P < 0.001), dotted enhancement during the pancreatic phase (50 % vs. 7 %; P < 0.001), duct-penetrating sign (46 % vs. 2 %; P < 0.001), enhanced duct sign (36 % vs. 2 %; P < 0.001) and capsule-like rim (46 % vs. 3 %; P < 0.001) were more frequently observed in AIP. Ring-like enhancement during the delayed phase (5 % vs. 46 %; P < 0.001) and peripancreatic strands with a length of at least 10 mm (5 % vs. 39 %; P = 0.001) were more frequently observed in PC. AIP was identified with 82 % sensitivity and 98 % specificity using four of these seven findings. Multivariate analysis revealed significant differences in dotted enhancement (P = 0.004), duct-penetrating sign (P < 0.001) and capsule-like rim (P = 0.007). The combination of CT findings may allow improvements in differentiating f-AIP from PC. (orig.)

    Full Text Available Primary squamous cell carcinoma (SCC of ampulla has seldom been reported. However, metastatic SCC to ampulla of Vater is well known. We report a case of primary SCC of ampulla of Vater coexistent with well-differentiated adenocarcinoma of the distal pancreatic duct. A 50-year-old female presented with evidence of obstructive jaundice. Endoscopic retrograde cholangio-pancreatography revealed bulging papilla with ulcero-infiltrative growth at the ampulla of Vater. An initial endoscopic biopsy of the ampullary mass showed a well-differentiated SCC. The patient underwent Whipple′s operation. Thorough sampling of the dilated portion of the pancreatic duct showed presence of well-differentiated adenocarcinoma of the distal pancreatic duct. Immunohistochemical study with synaptophysin and chromogranin was done with negative result, ruling out neuroendocrine differentiation. Also, a detailed clinical, endoscopic and radiological examination was carried out, that excluded the presence of primary SCC elsewhere.

    Pancreatic acinar cell carcinoma (ACC) is a rare entity. Herein we present the case of a 50-year-old male patient with an unlimited mass on the pancreatic corpus and tail with peripancreatic effusion and multiple metastases in the liver and spleen. A liver biopsy showed a pancreatic ACC. The patient received 9 cycles of gemcitabine plus oxaliplatin (GEMOX regimen), which had to be stopped because of a persistent grade 2 neuropathy. A CT scan showed complete response after 14 years. At the age of 61 years, a localized prostatic cancer was diagnosed, treated by prostatectomy. The patient carried a BRCA2 mutation. None of the precedent case reports describe a chemosensibility to the GEMOX regimen. In spite of the lack of study in these patients, chemotherapy with oxaliplatin seems to be the most effective. Long survival can be expected. PMID:26600777

Methods: The 45 patients suffering from pancreatic carcinoma were randomized into two groups. The patients in the experimental group (n=23 received HIFU in combination with gemcitabine and those in the control group (n=22 received gemcitabine alone. The effect and clinical benefit rates in the two groups were compared. The median survival time and 6-month and 12-month survival rates were calculated by Kaplan–Meier method and log-rank test. Results: The median survival time and 6-month survival rate were significantly higher in the experimental group than in the control group (8.91 months vs 5.53 months, 73.9% vs 40.9%, respectively P<0.05, but 12-month survival rate was not statistically different between the two groups (13.0% vs 4.5%, P>0.05. The clinical benefit rates in the experimental group and the control group were 69.6% and 36.3%, respectively (P<0.05. The pain remission rate in the experimental group was significantly higher than that in the control group (65.2% vs 31.8%, P<0.05. Conclusion: HIFU in combination with gemcitabine is better than gemcitabine alone. This combinatorial therapy may become a better and effective treatment for unresectable pancreatic carcinoma.

  8. The current status and evaluation of comprehensive therapy of pancreatic carcinoma

    International Nuclear Information System (INIS)

    The incidence of pancreatic carcinoma is increasing obviously in recent years with a serious threat to the people's life, and yet there is not a single treatment for obtaining satisfactory prognosis. At present, the radical resection is the primary method for resectable pancreatic carcinoma, together with radiotherapy can improve the surgical resection rate and reduce the dissemination of tumors. Intraoperative radiotherapy can alleviate the pain and increase the survival rate, but the role of postoperative radiotherapy and chemotherapy is still in controversial. There is a lot of advantages for regional chemotherapy theoretically, but lack of evidence in practice. Physical therapy and biological therapy in the treatment of pancreatic carcinoma have been recognized extensively. It is possible to change fundamentally the current status of treatment and to improve the long-term survival rates with the quality of life until establishing a comprehensive treatment system mainly depended on surgical resection with combination of radiotherapy, chemotherapy, physical and biological treatment. The interventional therapy has been significantly developed as an important palliative treatment during recent years. (authors)

    Full Text Available Abstract Background Although it is well known that the pancreatic ductal carcinoma may develop having a relationship to the mucous gland hyperplasia (MGH with atypia (PanIN-1B by PanIN system, the starting point of this atypical MGH is unclear. To know it, we examined the pancreas tissue using many methods described below. Methods 1. Twenty-seven surgically resected pancreas tissue specimens, including pancreatic ductal carcinomas (PDC, chronic pancreatitis and normal pancreas, were investigated using immunohistochemical stainings for MUC1, MUC6, 45M1, Ki67 and p53. 2. DNA extraction and analysis of K-ras mutation at codon 12 using microdissection method: The paraffin blocks with 16 regions including the intercalated duct cell (IC adjacant to the atypical MGH were prepared for DNA extraction. Mutation of K-ras codon 12 was analized and compared in enriched polymerase chain reaction-enzyme-linked minisequence assay (PCR-ELMA. Results 1. In the normal pancreas, although no positive cell was seen in 45M1, p53, Ki67, the cytoplasm of IC were always positive for MUC1 and sometimes positive for MUC6. In the pancreas with fibrosis or inflammation, MGH was positive for MUC6 and 45M1. And atypical MGH was positive for MUC1, MUC6 and 45M1. Some IC adjacent to the atypical MGH was positive for Ki67 as well as atypical MGH. The carcinoma cells in all cases of PDC were diffusely positive for MUC1, 45M1, p53 and Ki67, and focally positive for MUC6. 2. In K-ras mutation, we examined the regions including IC adjacent to the atypical MGH, because the immunohistochemical apomucin stainings of these regions resembled those of PDC as decribed above. And K-ras mutation was confirmed in 12 of 16 regions (75%. All mutations were a single mutation, in 6 regions GTT was detected, in 4 regions GAT was detected and in 2 region AGT was detected. Conclusion Some intercalated duct cell may be the starting point of the pancreatic ductal carcinoma, because the exhibitions of

    2016-01-01

    The role of radiation in locally advanced unresectable pancreatic cancer (LAPC) is controversial. Randomized trials evaluating standard doses of chemoradiation have not shown a significant benefit from the use of consolidative radiation. Results from non-randomized studies of 3–5-fraction stereotactic body radiotherapy (SBRT) have been similar to standard chemoradiation, but with less toxicity and a shorter treatment time. Doses of SBRT have been reduced to subablative levels for the sake of tolerability. The benefit of both options is unclear. In contrast, ablative doses can be delivered using an SBRT technique in 15–28 fractions. The keys to the delivery of ablative doses are computed tomography (CT) image guidance and respiratory gating. Higher doses have resulted in encouraging long-term survival results. In this review, we present a comprehensive solution to achieving ablative doses for selected patients with pancreatic tumors by using a combination of classical, modern and novel concepts of radiotherapy: fractionation, CT image guidance, respiratory gating, intentional dose heterogeneity, and simultaneous integrated protection.

  12. Pancreatic carcinoma development: new etiological and pathogenetic evidence

    Full Text Available Pancreatic adenocarcinoma (PAC is a very aggressive cancer with a poor prognosis. To date, the causes and pathogenetic mechanisms involved in the development of this malignancy remain largely unknown. Therefore, additional studies are required to improve our knowledge of the events that occur during the process of pancreatic carcinogenesis. The purpose of this article is to describe the most recent evidence, concerning the possible risk factors and mechanisms that may contribute to determine the development of PAC, as well as models, such as the tensegrity model, that may explain this complex process. Available studies suggest that approximately 15-20% of human malignancies are somehow associated with chronic infection. Some epidemiological research has shown that some infectious agents represent risk factors for PAC. In particular, several reports showed that the infection caused by some micro-organisms, including helicobacter pylori and some bacterial species of oral microbiota, as well as by viral agents, such as human immunodeficiency virus (HIV, and hepatitis B (HBV and C (HCV viruses, is associated with an increased probability of developing PAC. For the first time, observational studies and meta-analyses have suggested that HBV and HCV, two hepatotropic viruses with oncogenic properties, may be also risk factors for PAC. However, the small number of available reports, nearly all performed in Asian populations, limits their validity to these ethnic groups. Therefore, additional studies focusing on populations of different geographical areas and enrolling larger series of patients are required to confirm this association. Furthermore, an accurate description and a better understanding of the events and of the pathogenetic mechanisms involved in the process of pancreatic carcinogenesis, as proposed by the tensegrity model, might be a useful approach to effectively deal with this pathology.

  13. Interdependence of Gemcitabine Treatment, Transporter Expression, and Resistance in Human Pancreatic Carcinoma Cells

    Full Text Available Gemcitabine is widely used as first-line chemotherapeutic drug in the treatment of pancreatic cancer. Our previous experimental chemotherapy studies have shown that treatment of human pancreatic carcinoma cells with 5-fluorouracil (5-FU alters the cellular transporter expression profile and that modulation of the expression of multidrug resistance protein 5 (MRP5; ABCC5 influences the chemoresistance of these tumor cells. Here, we studied the influence of acute and chronic gemcitabine treatment on the expression of relevant uptake and export transporters in pancreatic carcinoma cells by reverse transcription-polymerase chain reaction (RT-PCR, quantitative RT-PCR, and immunoblot analyses. The specific role of MRP5 in cellular gemcitabine sensitivity was studied by cytotoxicity assays using MRP5-overexpressing and MRP5-silenced cells. Exposure to gemcitabine (12 nM for 3 days did not alter the messenger RNA (mRNA expression of MRP1, MRP3, MRP5, and equilibrative nucleoside transporter 1 (ENT1, whereas high dosages of the drug (20 µM for 1 hour elicited up-regulation of these transporters in most cell lines studied. In cells with acquired gemcitabine resistance (up to 160 nM gemcitabine, the mRNA or protein expression of the gemcitabine transporters MRP5 and ENT1 was upregulated in several cell lines. Combined treatment with 5-FU and gemcitabine caused a 5- to 40-fold increase in MRP5 and ENT1 expressions. Cytotoxicity assays using either MRP5-overexpressing (HEK and PANC-1 or MRP5-silenced (PANC1/shMRP5 cells indicated that MRP5 contributes to gemcitabine resistance. Thus, our novel data not only on drug-induced alterations of transporter expression relevant for gemcitabine uptake and export but also on the link between gemcitabine sensitivity and MRP5 expression may lead to improved strategies of future chemotherapy regimens using gemcitabine in pancreatic carcinoma patients.

    Objective: To compare the curative effectiveness of continuous transarterial infusion chemotherapy and systemic venous chemotherapy in treating patients with advanced pancreatic cancer, and to evaluate the value of selective continuous transarterial infusion chemotherapy in treating advanced pancreatic cancer. Methods: Of the 51 patients with advanced pancreatic cancer receiving chemotherapy with gemcitabine and 5-fluorouracil, 25 patients were treated with selective continuous transarterial infusion chemotherapy, 26 were treated with systemic venous chemotherapy, and curative effectiveness was analyzed retrospectively. Curative effectiveness included tumor volume, clinical benefit response (CBR), acute and subacute toxic reactions of antitumor drugs, survival rate and median survival time. Results: The objective effective rate in transarterial group was 32.0% versus 23.1% in systemic group without any significant difference (P = 0.475). Clinical benefit rates in transarterial group and systemic group were 80.0% and 50.0% respectively (P = 0.025). The 6-, 9- and 12-month accumulated survival rates and median survival time in transarterial group were higher than those of the systemic group (P = 0.002), the differences were statistically significant. However, the adverse reactions between the two groups were not statistically significant. Conclusion: Compared with systemic chemotherapy, continuous transarterial infusion chemotherapy with gemcitabine and 5-fluorouracil could improve clinical benefit rate and survival time of patients with advanced pancreatic cancer, it is safe and reliable, and the adverse reactions is less.

    Objective measurements of tissue area during histological examination of carcinoma can yield valuable prognostic information. However, such measurements are not made routinely because the current manual approach is time consuming and subject to large statistical sampling error. In this paper, a semi-automated image analysis method for measuring tissue area in histological samples is applied to the measurement of stromal tissue, cell cytoplasm and lumen in samples of pancreatic carcinoma and compared with the standard manual point counting method. Histological samples from 26 cases of pancreatic carcinoma were stained using the sirius red, light-green method. Images from each sample were captured using two magnifications. Image segmentation based on colour cluster analysis was used to subdivide each image into representative colours which were classified manually into one of three tissue components. Area measurements made using this technique were compared to corresponding manual measurements and used to establish the comparative accuracy of the semi-automated image analysis technique, with a quality assurance study to measure the repeatability of the new technique. For both magnifications and for each tissue component, the quality assurance study showed that the semi-automated image analysis algorithm had better repeatability than its manual equivalent. No significant bias was detected between the measurement techniques for any of the comparisons made using the 26 cases of pancreatic carcinoma. The ratio of manual to semi-automatic repeatability errors varied from 2.0 to 3.6. Point counting would need to be increased to be between 400 and 1400 points to achieve the same repeatability as for the semi-automated technique. The results demonstrate that semi-automated image analysis is suitable for measuring tissue fractions in histological samples prepared with coloured stains and is a practical alternative to manual point counting.

  17. Is it relevant that intra-arterial chemotherapy may be effective for advanced pancreatic cancer?

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Unresectable pancreatic cancers have an extremely dismal prognosis and chemoresistant nature. The treatment of pancreatic cancer is still problematic.Gemcitabine is a promising new agent that has been studied recently for palliation of advanced pancreatic cancer. However, the response rates have been highly variable, and are often irreproducible. To improve this low response rate, various treatments are needed because no standard treatment exists. Intra-arterial chemotherapy is considered to take advantage of the first pass effect of the drug, generating higher local drug concentrations in tumor cells with lower toxicity.Regional intra-arterial chemotherapy may provide high levels of cytostatic concentrations within the tumor and, simultaneously, a low rate of systemic side effects compared with systemic administration of anti-neoplastic drugs. Intra-arterial chemotherapy has been introduced as an alternative treatment for advanced pancreatic cancer. Further clinical trials of this method should be subjected to a prospective randomized controlled study for advanced pancreatic cancer.

    Objective: To study the value of multiple MR imaging techniques in the diagnosis of pancreatic carcinoma and the assessment of resectbility of the lesion. Methods: MR imaging was performed in 18 pa-tients with surgically and/or pathologically proven pancreatic carcinoma. GRE T1WI, TSE T2WI, GRE T1WI with fat suppression, delayed enhancement GRE T1WI, MRCP and 3D DCE MRA were used in MR scanning. Tumor involvement of the celiac trunk and its main branches, superior mesenteric artery,the portal, splenic and superior mesenteric veins were prospectively graded on a 0-4 scale based on cir-cumferential contiguity of tumor to vessel. Results: On GRE T1WI and TSE T2WI all the lesions showed slightly hypointense and hyperintense, respectively; On GRE T1WI with fat suppression, all the tumors obviously appeared hypointense; On delayed enhancement GRE T1WI, the lesions displayed irregularly circular enhancement in 14 patients and well-distributed enhancement in 4 patients. MRCP showed exten-sive bile and main pancreatic duct dilatation with typical "double-duct" sign in 8 patients. On 3D DCE MRA, we thought it was unresectable with more than half circumferential involvement of tumor to vessel,so that the portal, splenic and superior mesenteric veins were involved with 56% (10/18), 39% (7/18)and 67% (12/18), respectively. The celiac trunk and its main branches and superior mesenteric arteries were involved with 22% (4/18) and 17% (3/18), respectively. The pancreatic lesions in 2 cases could be completely resected in the evaluation of MR imaging, which was fitted to the findings of operation by pan-creatoduodenectomy. The pancreatic lesions in other 2 cases were partly, resected because there was tumor extension to superior mesenteric vein and/or artery. The tumors in the remaining 14 patients were too large and involved peripancreatic vessels or there were stomach or liver metastases, so these patients were only treated by choledochojejunostomy and gastrojejunstomy.

    Pancreatic metastases from renal cell carcinoma are uncommon and their prognostic significance is not well defined. In this analysis we evaluated the outcome of patients with pancreatic metastases treated with either targeted therapies or local treatment to the pancreas. Patients with pancreatic metastases from renal cell carcinoma treated between 1993 and 2014 were identified from 11 European centers. Clinical records were retrospectively reviewed. Kaplan-Meier method and log-rank test were used to evaluate progression-free survival and overall survival. Cox’s proportional hazard models were used for survival analysis. In total, 276 PM patients were evaluated, including 77 (28%) patients treated by either surgery or radiotherapy to the pancreas, and 256 (93%) who received systemic therapy. Median time from nephrectomy to diagnosis of pancreatic metastases was 91 months (IQR 54–142). Disease control rate after first-line TTs was 84%, with a median progression-free survival of 12 months (95% CI 10–14). Median overall survival was 73 months (95% CI 61–86) with a 5-year OS of 58%. Median OS of patients treated with local treatment was 106 months (95% CI 78–204) with a 5-year overall survival of 75%. On multivariable analysis, nephrectomy (HR 5.31; 95%CI 2.36–11.92; p<0.0001), Memorial Sloan Kettering/International Metastatic RCC Database Consortium prognostic score (HR 1.45, 95% CI 0.94–2.23 for intermediate vs good vs risk; HR 2.76 95%, CI 1.43–5.35 for poor vs good risk p = 0.0099) and pancreatic local treatment (HR 0.48; 95%CI 0.30–0.78 p = 0.0029) were associated with overall survival. Difference in median OS between patients with PM and that reported in a matched-control group of mRCC patients with extrapancreatic metastases was statistically significant (p < .0001). Pancreatic metastases from renal cell carcinoma usually occur years after nephrectomy, are associated with an indolent behavior and a prolonged survival. Targeted therapies and

  1. Diagnosis and staging of pancreatic carcinoma: MRI versus multislice-CT - A prospective study

    International Nuclear Information System (INIS)

    Purpose: To evaluate multislice-CT versus MRI in the diagnosis and staging of pancreatic carcinoma in a prospective multi-reader analysis. Materials and Methods: Fifty patients with suspected pancreatic carcinoma underwent both multislice-CT (4-Row, 'hydro-technique') and state-of-the-art MRI (two 1.5 T units). In correlation with histopathologic findings or in case of a non-lesion diagnosis by follow-up (6-month interval), we evaluated MRI versus CT in a multi-reader analysis (2 reader pairs) for: 1. diagnostic quality; 2. examination time; 3. accuracy of potential respectability; 4. kappa analysis of observer variations; and 5. overall diagnostic reliability. Results: A total of 28 lesions (n=22 malignant, n=6 benign) were present in the cohort group versus 22 patients without a focal lesion (n=10 pancreatitis, n=12 no tumor). For lesion detection, CT had a sensitivity of 100/89% (reader pair 1/2) and specificity of 77%, and MRI had a sensitivity of 75/89% and specificity of 77/73%. For the subgroup of adenocarcinomas of the pancreas (n=17), we found a sensitivity of 100% and a specificity of 61% for CT versus a sensitivity of 82/94% and a specificity of 67/61% for MRI. The accuracy for determining the resectability was 91/82% for CT and 90/82% for MRI. The kappa analysis showed a good correlation for CT (0.71) and a moderate correlation of both groups for MRI (0.49). Conclusion: CT and MRI showed comparable results in the detection of pancreatic carcinomas as well as in the determination of resectability. Chronic pancreatitis as a 'tumor-like-lesion' was the major factor of a missed diagnosis. The results of multi-reader analysis for both reading groups were almost identical with a moderate to good kappa correlation. There is no reason to prefer MRI (more expensive) over CT for patients with the presumptive diagnosis of pancreatic cancer. (orig.)

    AIM: To study the possible actions and mechanisms of peroxisome proliferator-activated receptor γ (PPARγ), a ligand-activated transcription factor, in pancreatic carcinogenesis,especially in angiogenesis.METHODS: Expressions of PPARγ and retinoid acid receptor (RXRα) were examined by reverse-transcription polymerase chain reaction (RT-PCR) with immunocytochemical staining. Pancreatic carcinoma cells, PANC-1,were treated either with 9-cis-RA, a ligand of RXRα,or with 15-deoxy-Δ12,14 prostaglandin J2(15d-PGJ2), a ligand of PPARγ, or both. Antiproliferative effect was evaluated by cell viability using methyltetrazolium (MTT) assay. A pancreatic carcinoma xenograft tumor model of nude mice was established by inoculating PANC-1 cells subcutaneously. Rosiglitazone, a specific ligand of PPARγ, was administered via water drinking in experimental group of nude mice. After 75 d, all mice were sacrificed. Expression of proliferating cell nuclear antigen (PCNA) in tumor tissue was examined with immunohistochemical staining. Expression of vascular endothelial growth factor (VEGF) mRNA in PANC-1 cells, which were treated with 15d-PGJ2 or 9-cis-RA at variousconcentrations or different duration, was detected by semi-quantitative RT-PCR. Effects of Rosiglitazone on changes of microvascular density (MVD) and VEGF expression were investigated in xenograft tumor tissue. Neovasculature was detected with immunohistochemistry staining labeled with anti-Ⅳ collagen antibody, and indicated by MVD.RESULTS: RT-PCR and immunocytochemical staining showed that PPARγ and RXRα were expressed in PANC-1 cells at both transcription level and translation level. MTT assay demonstrated that 15d-PGJ2, 9-cis-RA and their combination inhibited the growth of PANC-1 cells in a dose-dependent manner. 9-cis-RA had a combined inhibiting action with 15d-PGJ2 on the growth of pancreatic carcinoma. In vivo studies revealed that Rosiglitazone significantly suppressed the growth of pancreatic carcinoma

    We sought to evaluate the capability of spectral CT to detect the therapeutic response to {sup 125}I interstitial brachytherapy in a pancreatic carcinoma xenograft nude mouse model. Twenty mice bearing SWl990 human pancreatic cancer cell xenografts were randomly separated into two groups: experimental (n = 10; 1.0 mCi) and control (n = 10; 0 mCi). After a two-week treatment, spectral CT was performed. Contrast-to-noise ratio (CNR) and iodine concentration (IC) in the lesions were measured and normalized to the muscle tissue, and nIC CD31 immunohistochemistry was used to measure microvessel density (MVD). The relationships between the nIC and MVD of the tumours were analysed. The nIC of the experimental group was significantly lower than that of the control group during the multiphase examination. A significant difference in the MVD was observed between the two groups (P <0.001). The nIC values of the three-phase scans have a certain positive correlation with MVD (r = 0.57, p < 0.0001; r = 0.48, p = 0.002; r = 0.63, p = 0.0017 in the 10, 25, and 60 s phase, respectively). Spectral CT can be a useful non-invasive imaging modality in evaluating the therapeutic effect of {sup 125}I interstitial brachytherapy to a pancreatic carcinoma. (orig.)

    AIM:To investigate second-line chemotherapy in gemcitabine-pretreated patients with advanced or metastatic pancreatic cancer [(frequency,response,outcome,course of carbohydrate antigen 19-9 (CA 19-9)].METHODS:This retrospective study included all patients with advanced or metastatic pancreatic cancer (adenocarcinoma or carcinoma) treated with secondline chemotherapy in our center between 2000 and 2008.All patients received first-line chemotherapy with gemcitabine,and prior surgery or radiotherapy was permitted.We analyzed each chemotherapy protocol for second-line treatment,the number of cycles and the type of combination used.The primary endpoint was overall survival.Secondary endpoints included progression-free survival,response rate,grade 3-4 toxicity,dosage modifications and CA 19-9 course.RESULTS:A total of eighty patients (38%) underwent a second-line therapy among 206 patients who had initially received first-line treatment with a gemcitabine-based regimen.Median number of cycles was 4 (range:1-12) and the median duration of treatment was 2.6 mo (range:0.3-7.4).The overall disease control rate was 40.0%.The median overall survival and progression-free survival from the start of second-line therapy were 5.8 (95% CI:4.1-6.6) and 3.4 mo (95% CI:2.4-4.2),respectively.Toxicity was generally acceptable.Median overall survival of patients with a CA 19-9 level declining by more than 20% was 10.3 mo (95% CI:4.5-11.6) vs 5.2 mo (95% CI:4.0-6.4) for others (P =0.008).CONCLUSION:A large proportion of patients could benefit from second-line therapy,and CA 19-9 allows efficient treatment monitoring both in first and secondline chemotherapy.

  8. Fluorine-18 fluorodeoxyglucose positron emission tomography in the differential diagnosis of pancreatic carcinoma: a report of 106 cases

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate fluorine-18 fluorodeoxyglucose positron emission tomography ([18F[FDG PET) as a tool for the differential diagnosis of pancreatic carcinoma while taking into account serum glucose level. A group of 106 patients with unclear pancreatic masses were recruited for the study. PET was performed following intravenous administration of an average of 190 MBq [18F[FDG. Focally increased glucose utilisation was used as the criterion of malignancy. In addition, the ''standardised uptake value'' (SUV) was determined 45 min after injection. Carcinoma of the pancreas was demonstrated histologically in 74 cases, and chronic pancreatitis in 32 cases. Employing visual evaluation, 63 of the 74 (85%) pancreatic carcinomas were identified by PET. In 27 of the 32 cases (84%) of chronic pancreatitis it was possible to exclude malignancy. False-negative results (n=11) were obtained mostly in patients with raised serum glucose levels (10 out of 11), and false-positives (n=5) in patients with inflammatory processes of the pancreas. Thus PET showed an overall sensitivity of 85%, a specificity of 84%, a negative predictive value of 71%, and a positive predictive value of 93%. In a subgroup of patients with normal serum glucose levels (n=72), the results were 98%, 84%, 96% and 93%, respectively. Quantitative assessment yielded a mean SUV of 6.4±3.6 for pancreatic carcinoma as against a value of 3.6±1.7 for chronic pancreatitis (P<0.001), without increasing the diagnostic accuracy. This shows PET to be of value in assessing unclear pancreatic masses. The diagnostic accuracy of PET examinations is very dependent on serum glucose levels. (orig.). With 2 figs., 3 tabs

    2009-01-01

    Gastrectomy is commonly performed for both benign and malignant lesions. Although the incidence of post-gastrectomy acute pancreatitis (PGAP) is low compared to other well-recognized post-operative complications, it has been reported to be associated with a high mortality rate. In this article, we describe a 70-year-old man with asymptomatic pancreatic divisum who underwent palliative subtotal gastrectomy for an advanced gastric cancer with liver metastasis. His postoperative course was complicated by acute pancreatitis and intra-abdominal sepsis. The patient eventually succumbed to multiple organ failure despite surgical debridement and drainage, together with aggressive antibiotic therapy and nutritional support. For patients with pancreas divisum or dominant duct of Santorini who fail to follow the normal post-operative course after gastrectomy, clinicians should be alert to the possibility of PGAP as one of the potential diagnoses. Early detection and aggressive treatment of PGAP might improve the prognosis.

    International Nuclear Information System (INIS)

    Objective: To study the effect of PUMA gene mediated by recombinant adenovirus vector combined with radiation on the pancreatic carcinoma. Methods: The PANC-1 cells were infected with Ad- PUMA (MOI=10, 50 and 100, respectively) for 48 h. The expression of PUMA mRNA and protein was detected by RT-PCR and Western blot, respectively. PANC-1 cells were divided into 4 groups: control group, transfection group, irradiation group and combined treatment group. The cell growth inhibition rate and apoptotic rate of PANC-1 cells were assessed by MTT assay and flow cytometry. Human pancreatic carcinomas were transplanted subcutaneously in nude mice, which were randomized into 4 groups: control group, transfection group, irradiation group and combined treatment group. Tumor growth rate and apoptotic index at different time points were recorded in 35 days. Results: The expression of PUMA mRNA and protein was increased with the increase of MOI of Ad-PUMA, which was does-dependant (MOI=10, mRNA=0.46± 0.02, protein=0.75± 0.09; MOI=50, mRNA=1.12±0.09, protein=1.01±0.18; MOI=100, mRNA=1.50±0.08, protein= 1.80±0.15; P3, (39.5±9.23)mm3, (33.6±10.3)mm3 and (52.0±11.43)mm3, respectively, P<0.05]. And the apoptotic index was increased in the same manner (AI=0.43±0.05, 0.29±0.10, 0.24±0.05 and 0.00±0.00, respectively, P<0.05). Conclusions: Recombinant adenoviral-mediated PUMA gene combined with irradiation could increase the cell-killing effect on pancreatic carcinoma. It is better than that of either one kind of therapy.

    2011-01-01

    Full Text Available Small cell lung carcinoma represents a group of highly malignant tumors giving rise to early and widespread metastasis at the time of diagnosis. However, the pancreas is a relatively infrequent site of metastasis by this neoplasm, and there are only occasional reports on its fine needle aspiration (FNA cytology diagnosis. A 66-year-old man presented with extensive mediastinal lymphadenopathy and a mass in the pancreatic tail. Ultrasound-guided FNA smears from the pancreatic mass contained small, round tumor cells with extensive nuclear molding. The cytodiagnosis was metastatic small cell carcinoma. Immunocytochemical staining showed that a variable number of neoplastic cell were positive for cytokeratin, chromogranin A, neurone-specific enolase and synaptophysin but negative for leukocyte common antigen. The trans-bronchial needle aspiration was non-diagnostic, but biopsy was suspicious of a small cell carcinoma. This case represents a rare metastatic lesion in the pancreas from small cell lung carcinoma, diagnosed by FNA cytology.

    Objective: To explore the clinical efficacy of transcatheter arterial infusion (TAI) chemotherapy for advanced malignant pancreatic islet cell tumors. Methods: Four patients (3 malignant insulin tumors, 1 non-functional malignant pancreatic islet cell tumor) with unresectable advanced malignant tumors were carried out TAI via celiac artery. The three malignant insulin tumors with multiple hepatic metastases were further performed with transcatheter arterial chemoembolization (TACE). The therapeutic cycles were repeated with intervals of 1-2 months. Results: Eleven therapeutic cycles (mean 2.8)were accomplished in 4 cases. Follow-up for 2-8 months, the clinical PR were achieved in three cases, furthermore with SD in one case. The clinical uprising blood glucose became normal in all three cases, and the abdominal distention and bellyache were relieved in the patient with non-functional malignant pancreatic islet cell tumor. No serious adverse effects occurred. Conclusions: TAI for unresectable advanced malignant pancreatic islet cell tumors is safe and effective. (authors)

  17. Pancreatic Metastasis of High-Grade Papillary Serous Ovarian Carcinoma Mimicking Primary Pancreas Cancer: A Case Report

    Directory of Open Access Journals (Sweden)

    Yusuf Gunay

    2012-01-01

    Full Text Available Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinoma. A cystic lesion was revealed by an abdominal computerized tomography (CT performed in her follow up . It was considered as primary mid portion of pancreatic cancer and a distal pancreatectomy was performed. The final pathology showed high-grade papillary serous adenocarcinoma morphologically similar to the previously diagnosed ovarian cancer. Discussion. Metastatic pancreatic cancers should be considered in patients who present with a solitary pancreatic mass and had a previous non-pancreatic malignancy. Differential diagnosis of primary pancreatic neoplasm from metastatic malignancy may be very difficult. A biopsy for tissue confirmation is required to differentiate primary and secondary pancreatic tumors. Although, the value of surgical resection is poorly documented, resection may be considered in selected patients. Conclusion. Pancreatic metastasis of ovarian papillary serous adenocarcinoma has to be kept in mind when a patient with pancreatic mass has a history of ovarian malignancy.

  18. [Resection for advanced pancreatic cancer following multimodal therapy].

    2016-05-01

    Pancreatic cancer patients presenting with borderline resectable or locally advanced unresectable tumors remain a therapeutic challenge. Despite the lack of high quality randomized controlled trials, perioperative neoadjuvant treatment strategies are often employed for this group of patients. At present the FOLFIRINOX regimen, which was established in the palliative setting, is the backbone of neoadjuvant therapy, whereas local ablative treatment, such as stereotactic irradiation and irreversible electroporation are currently under investigation. Resection after modern multimodal neoadjuvant therapy follows the same principles and guidelines as upfront surgery specifically regarding the extent of resection, e.g. lymphadenectomy, vascular resection and multivisceral resection. Because it is still exceedingly difficult to predict tumor response after neoadjuvant therapy, a special treatment approach is necessary. In the case of localized stable disease following neoadjuvant therapy, aggressive surgical exploration with serial frozen sections at critical (vascular) margins might be necessary to minimize the risk of debulking procedures and maximize the chance of a curative resection. A multidisciplinary and individualized approach is mandatory in this challenging group of patients. PMID:27138271

    Full Text Available Yoshiaki Andoh,1,2 Naohiko Makino,2 Mitsunori Yamakawa11Department of Pathological Diagnostics, 2Department of Gastroenterology, Yamagata University School of Medicine, Yamagata, JapanBackground: It is unclear whether there are any differences in the induction of cytotoxic T lymphocytes (CTL and CD4+CD25high regulatory T-cells (Tregs among dendritic cells (DCs fused with different pancreatic carcinomas. The aim of this study was to compare the ability to induce cytotoxicity by human DCs fused with different human pancreatic carcinoma cell lines and to elucidate the causes of variable cytotoxicity among cell lines.Methods: Monocyte-derived DCs, which were generated from peripheral blood mononuclear cells (PBMCs, were fused with carcinoma cells such as Panc-1, KP-1NL, QGP-1, and KP-3L. The induction of CTL and Tregs, and cytokine profile of PBMCs stimulated by fused DCs were evaluated.Results: The cytotoxicity against tumor targets induced by PBMCs cocultured with DCs fused with QGP-1 (DC/QGP-1 was very low, even though PBMCs cocultured with DCs fused with other cell lines induced significant cytotoxicity against the respective tumor target. The factors causing this low cytotoxicity were subsequently investigated. DC/QGP-1 induced a significant expansion of Tregs in cocultured PBMCs compared with DC/KP-3L. The level of interleukin-10 secreted in the supernatants of PBMCs cocultured with DC/QGP-1 was increased significantly compared with that in DC/KP-3L. Downregulation of major histocompatibility complex class I expression and increased secretion of vascular endothelial growth factor were observed with QGP-1, as well as in the other cell lines.Conclusion: The present study demonstrated that the cytotoxicity induced by DCs fused with pancreatic cancer cell lines was different between each cell line, and that the reduced cytotoxicity of DC/QGP-1 might be related to the increased secretion of interleukin-10 and the extensive induction of Tregs

    Full Text Available Ghrelin is a peptide that is secreted from the stomach and plays a role in appetite, weight gain, and skeletal muscle composition. Thus, compounded human ghrelin is a candidate drug for improving nutritional status after pancreatic surgery. However, in patients with pancreatic carcinomas, adverse influences on the occult tumor growth of ghrelin-induced secretion are a concern. The present study describes the effects of the administration of compounded human ghrelin on weight gain and pancreatic cancer cell growth in a mouse model. Changes in body weight and tumor growth in a subcutaneously transplanted pancreatic carcinoma cell line in vivo (5-week-old BALB/c-nu/nu mice were examined with or without the administration of compounded human ghrelin. Compounded human ghrelin was administered at 44 days after post-transplantation” Changes in weight were not significantly different between the control and compounded human ghrelin groups 8 days after compounded human ghrelin administration, and no association between weight and concentration of compounded human ghrelin was identified. Tumor growth after the administration of compounded human ghrelin was significantly lower than that of the control group, with the magnitude of the decrease being associated with increasing compounded human ghrelin concentration (p<0.05. At 6 and 8 days after compounded human ghrelin administration, increases in tumor weights of the control groups (0.5±0.3 g and 0.9±0.2 g, respectively were significantly greater than those observed for groups receiving 3, 15, and 30 nmol per kg of compounded human ghrelin (0.1 and 0.2, 0.2 and 0.3, and 0.2 and 0.3, respectively. There were no adverse effects of compounded human ghrelin administration. Plasma leptin levels were significantly lower in cancer cells compared with the control vehicle (p<0.05, which was decreased in mice receiving 30nmol per kg of compounded human ghrelin in comparison with those receiving vehicle (p<0

    Full Text Available We review the utility of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA, a rapid, safe, cost-effective, and accurate diagnostic modality for evaluating pancreatic tumors. EUS-FNA is currently used for the diagnosis and staging of pancreatic tumors. The sensitivity of EUS-FNA for pancreatic malignancy ranges from 75% to 94%, and its specificity approaches 100% in most studies. However, EUS-FNA has some limitations in the diagnosis of well-differentiated or early-stage cancers. Recent evidence suggests that molecular biological analysis using specimens obtained by EUS-FNA improves diagnostic sensitivity and specificity, especially in borderline cytological cases. It was also reported that additional information regarding patient response to chemotherapy, surgical resectability, time to metastasis, and overall survival was acquired from the genetic analysis of specimens obtained by EUS-FNA. Other studies have revealed that the analysis of KRAS, MUC, p53, p16, S100P, SMAD4, and microRNAs is helpful in making the diagnosis of pancreatic carcinoma. In this paper, we describe the present state of genetic diagnostic techniques for use with EUS-FNA samples in pancreatic diseases. We also discuss the role of molecular biological analyses for the diagnosis of pancreatic carcinoma.

    AIM: To identify new diagnostic markers and drug targets,the gene expression profiles of pancreatic cancer were compared with that of adjacent normal tissues utilizing cDNA microarray analysis.METHODS: cDNA probes were prepared by labeling mRNA from samples of six pancreatic carcinoma tissues with Cy5dUTP and mRNA from adjacent normal tissues with Cy3dUTP respectively through reverse transcription. The mixed probes of each sample were then hybridized with 12 800cDNA arrays (12 648 unique human cDNA sequences), and the fluorescent signals were scanned by ScanArray 3 000scanner (General Scanning, Inc.). The values of CyS-dUTP and Cy3-dUTP on each spot were analyzed and calculated by ImaGene 3.0 software (BioDiscovery, Inc.). Differentially expressed genes were screened according to the criterion that the absolute value of natural logarithm of the ratio of Cy5-dUTP to Cy3-dUTP was greater-than 0.69.RESETS: Among 6 samples investigated, 301 genes, which accounted for 2.38% of genes on the microarry slides,exhibited differentially expression at least in 5. There were 166 over-expressed genes including 136 having been registered in Genebank, and 135 under-expressed genes including 79 in Genebank in cancerous tissues.CONCLUSION: Microarray analysis may provide invaluable information on disease pathology, progression, resistance to treatment, and response to cellular microenvironments of pancreatic carcinoma and ultimately may lead to improving early diagnosis and discovering innovative therapeutic approaches for cancer.

  7. Spiclomazine induces apoptosis associated with the suppression of cell viability, migration and invasion in pancreatic carcinoma cells.

    Directory of Open Access Journals (Sweden)

    Wenjing Zhao

    Full Text Available The effective treatment for pancreatic carcinoma remains critically needed. Herein, this current study showed that spiclomazine treatment caused a reduction in viability in pancreatic carcinoma cell lines CFPAC-1 and MIA PaCa-2 in vitro. It was notable in this regard that, compared with pancreatic carcinoma cells, normal human embryonic kidney (HEK-293 and liver (HL-7702 cells were more resistant to the antigrowth effect of spiclomazine. Biochemically, spiclomazine treatment regulated the expression of protein levels in the apoptosis related pathways. Consistent with this effect, spiclomazine reduced the mitochondria membrane potential, elevated reactive oxygen species, and activated caspase-3/9. In addition, a key finding from this study was that spiclomazine suppressed migration and invasion of cancer cells through down-regulation of MMP-2/9. Collectively, the proposed studies did shed light on the antiproliferation effect of spiclomazine on pancreatic carcinoma cell lines, and further clarified the mechanisms that spiclomazine induced apoptosis associated with the suppression of migration and invasion.

  8. Angiotensin II type 2 receptor signaling significantly attenuates growth of murine pancreatic carcinoma grafts in syngeneic mice

    International Nuclear Information System (INIS)

    Pancreatic cancer is one of the most aggressive human malignancies, with a very poor prognosis. To evaluate the effect of angiotensin II (Ang II) type 2 receptor (AT2) expression in the host's body on the growth of pancreatic carcinoma, we have investigated the growth of mouse pancreatic ductal carcinoma grafts in syngeneic wild type and AT2 receptor-deficient (AT2-KO) mice. The role of AT2 receptor-signaling in stromal cells on the growth of murine pancreatic carcinoma cells (PAN02) was studied using various in vitro and in vivo assays. In vivo cell proliferation, apoptosis, and vasculature in tumors were monitored by Ki-67 immunostaining, TUNEL assay, and von Willebrand factor immunostaining, respectively. In the co-culture study, cell proliferation was measured by MTT cell viability assay. All the data were analyzed using t-test and data were treated as significant when p < 0.05. Our results show that the growth of subcutaneously transplanted syngeneic xenografts of PAN02 cells, mouse pancreatic ductal carcinoma cells derived from the C57/BL6 strain, was significantly faster in AT2-KO mice compared to control wild type mice. Immunohistochemical analysis of tumor tissue revealed significantly more Ki-67 positive cells in xenografts grown in AT2-KO mice than in wild type mice. The index of apoptosis is slightly higher in wild type mice than in AT2-KO mice as evaluated by TUNEL assay. Tumor vasculature number was significantly higher in AT2-KO mice than in wild type mice. In vitro co-culture studies revealed that the growth of PAN02 cells was significantly decreased when grown with AT2 receptor gene transfected wild type and AT2-KO mouse-derived fibroblasts. Faster tumor growth in AT2-KO mice may be associated with higher VEGF production in stromal cells. These results suggest that Ang II regulates the growth of pancreatic carcinoma cells through modulating functions of host stromal cells; Moreover, Ang II AT2 receptor signaling is a negative regulator in the

    We report a case of a 74-year-old man with a metastatic anaplastic pancreatic carcinoma (APC). After an early tumour progression on first-line chemotherapy with cisplatin and gemcitabine, even though it was badly tolerated, he was treated with a combination of systemic modified FOLFIRI and high-intensity focused ultrasound (HIFU) on the pancreatic mass. A tumour showing partial response with a clinical benefit was obtained. HIFU was preferred to radiotherapy because of its shorter course and minimal side effects, in order to improve the patient’s clinical conditions. The patient is currently on chemotherapy, asymptomatic with a good performance status. In referral centres, with specific expertise, HIFU could be safely and successfully combined with systemic chemotherapy for treatment of metastatic pancreatic carcinoma. PMID:27170835

  19. Treatment of Locally Advanced Pancreatic Cancer: The Role of Radiation Therapy

    International Nuclear Information System (INIS)

    Pancreatic cancer remains associated with an extremely poor prognosis. Surgical resection can be curative, but the majority of patients present with locally advanced or metastatic disease. Treatment for patients with locally advanced disease is controversial. Therapeutic options include systemic therapy alone, concurrent chemoradiation, or induction chemotherapy followed by chemoradiation. We review the evidence to date regarding the treatment of locally advanced pancreatic cancer (LAPC), as well as evolving strategies including the emerging role of targeted therapies. We propose that if radiation is used for patients with LAPC, it should be delivered with concurrent chemotherapy and following a period of induction chemotherapy.

    BACKGROUND It has been demonstrated that the humanized clivatuzumab tetraxetan (hPAM4) antibody targets pancreatic ductal carcinoma selectively. After a trial of radioimmunotherapy that determined the maximum tolerated dose of single-dose yttrium-90-labeled hPAM4 (90Y-hPAM4) and produced objective responses in patients with advanced pancreatic ductal carcinoma, the authors studied fractionated radioimmunotherapy combined with low-dose gemcitabine in this disease. METHODS Thirty-eight previously untreated patients (33 patients with stage IV disease and 5 patients with stage III disease) received gemcitabine 200 mg/m2 weekly for 4 weeks with 90Y-hPAM4 given weekly in Weeks 2, 3, and 4 (cycle 1), and the same cycle was repeated in 13 patients (cycles 2–4). In the first part of the study, 19 patients received escalating weekly 90Y doses of 6.5 mCi/m2, 9.0 mCi/m2, 12.0 mCi/m2, and 15.0 mCi/m2. In the second portion, 19 additional patients received weekly doses of 9.0 mCi/m2 or 12.0 mCi/m2. RESULTS Grade 3/4 thrombocytopenia or neutropenia (according to version 3.0 of the National Cancer Institute’s Common Terminology Criteria for Adverse Events) developed in 28 of 38 patients after cycle 1 and in all retreated patients; no grade >3 nonhematologic toxicities occurred. Fractionated dosing of cycle 1 allowed almost twice the radiation dose compared with single-dose radioimmunotherapy. The maximum tolerated dose of 90Y-hPAM4 was 12.0 mCi/m2 weekly for 3 weeks for cycle 1, with ≤9.0 mCi/m2 weekly for 3 weeks for subsequent cycles, and that dose will be used in future trials. Six patients (16%) had partial responses according to computed tomography-based Response Evaluation Criteria in Solid Tumors, and 16 patients (42%) had stabilization as their best response (58% disease control). The median overall survival was 7.7 months for all 38 patients, including 11.8 months for those who received repeated cycles (46% [6 of 13 patients] ≥1 year), with improved efficacy at

    Full Text Available Sebaceous gland carcinomas (SGC are highly malignant lid tumors which originate from meibomian glands and rarely from the gland of Zeis, sebaceous gland of caruncle, eyebrows and periocular skin. In many cases correct diagnosis of SGC is delayed because of its ability to masquerade as a variety of other ocular conditions.A forty year old male presented with a left upper eyelid swelling with an ulcerated wound on its nasal aspect. A differential diagnosis of sebaceous gland carcinoma or preseptal cellulitis was made. Contrast enhanced computed tomography showed an ill defined soft tissue density mass in the left orbit encasing the whole of the optic nerve. A total exentration was performed. A diagnosis of meibomian gland carcinoma was confirmed on histopathology.This is a report of an advanced sebaceous gland carcinoma with deep orbital extension. An early diagnosis and appropriate treatment may decrease the long term morbidity and extend the survival rate of such patients.

    International Nuclear Information System (INIS)

    Objective: To explore the dynamic changes of serum tumor markers after CT-guided radioactive 125I-seed implantation treatment in patients with pancreatic carcinoma and to assess the therapeutic effectiveness of 125I-seed implantation. Methods: CT-guided radioactive 125I-seed implantation was performed in 19 patients with unresectable advanced pancreatic cancer. Treatment planning system was used to reconstruct 3-dimentional images of the tumor, and the quantity and distribution of 125I-seeds to be implanted were thus determined. Under CT guidance 125I-seeds were embedded into pancreatic cancer. Before and after the 125I-seed implantation the levels of serum tumor markers, including CEA, CA19-9 and CA50, were determined by using radioimmunoassay method. The clinical effects were observed and the therapeutic results were statistically analyzed. Results: The pain stared to be relieved 2 to 5 days after implantation. The total effective rate (CR + PR) at one and three months after treatment was 68.42% (13 /19) and 63.16% (12 /19) respectively. One month after 125I-seed implantation, the levels of serum CEA, CA19-9 and CA50 were significantly different to that determined before implantation in all cases (P 125I-seed implantation is a safe and effective interventional treatment for advanced pancreatic cancer with reliable short-term result and remarkable pain-relieving effect. Moreover, this therapy can significantly lower the levels of many serum tumor markers, which play some suggestive roles in evaluating the clinical curativeness. (authors)

    2014-03-01

    Full Text Available Pancreatic neuroendocrine tumors (NETs, including poorly differentiated carcinomas (NECs, are rarely encountered. The majority of these tumors do not secrete excess hormones, but functioning NETs produce large amounts of vasoactive peptides and may cause carcinoid syndrome. Synthetic somatostatin analogs (SSAs have been widely used in NETs for control of hormonal syndromes. Here, we present a case of poorly differentiated, grade 3 pancreatic NEC associated with carcinoid syndrome, for which adequate symptom control was achieved for 2 years and 4 months using the long-acting SSA lanreotide Autogel®. In February 2009, a 55-year-old woman presented with episodes of flushing, diarrhea and epigastric pain. Imaging techniques revealed the presence of a metabolically active mass expressing somatostatin receptors in the hilar area of the liver. Histopathological examination confirmed the malignant nature of the mass, which was identified as a poorly differentiated grade 3 pancreatic NEC (TNM staging: T4NxM0. Therapeutic options were limited for the patient because of the extent of the primary mass involving the celiac axis, severe gastrointestinal toxicity experienced as a side effect of chemotherapy with cisplatin-etoposide and, later in the course of the disease, extensive liver metastases and carcinoid heart syndrome. Along with a palliative debulking surgery and right portal vein embolization, biotherapy with a high dose of lanreotide Autogel (120 mg/14 days contributed to alleviation of symptoms caused by hormone overproduction, even after the development of liver metastases. These results suggest that patients with poorly differentiated NECs who exhibit signs of carcinoid syndrome can benefit from treatment with somatostatin analogs.

  7. Pancreatic carcinoma: MR, MR angiography and dynamic helical CT in the evaluation of vascular invasion

    International Nuclear Information System (INIS)

    Objective: To assess the value of MR angiography in combination with contrast-enhanced MR imaging, and to compare MR imaging including MR angiography with dynamic contrast-enhanced dual phase helical CT in the preoperative assessment of vascular invasion in patients with suspected pancreatic carcinoma. Methods and material: MR imaging only, MR imaging including MR angiography and dynamic contrast-enhanced dual phase helical CT images of 48 patients who were operated due to suspicion of pancreas cancer were correlated with the surgery results in terms of vascular invasion. Pathologic diagnosis were pancreatic adenocarcinoma in 31 patients of which nine had surgically confirmed vascular invasion. Sensitivity, specificity, predictive values (including 95% confidence intervals) and accuracy of MR imaging only, MR imaging including MR angiography and helical CT were calculated. Results: Sensitivity, specificity, positive and negative predictive values and accuracy were 56, 100, 100, 85, 87%; 67, 100, 100, 88, 90% and 67, 100, 100, 88, 90%, respectively, for MR imaging only, MR imaging including MR angiography and helical CT in the adenocarcinoma group. The corresponding figures in the overall study group were 56, 97, 83, 90, 90%; 67, 97, 86, 93, 92% and 67, 97, 86, 93, 92%. Confidence intervals (95%) showed that the differences in the diagnostic efficacy of the techniques were not statistically significant in the overall study group, but the confidence intervals were undefined in the adenocarcinoma group due to the small sample size. Conclusion: Diagnostic efficacy of MR imaging when combined with MR angiography is equal to that of dynamic contrast-enhanced dual phase helical CT in the assessment of vascular invasion of pancreatic tumors

    Objective: To study the therapeutic and toxic effects of 32P-chromic phosphate-poly (L-lactic) acid (32P-CP-PLLA) microparticle intratumoral administration into BALB/c nude mice bearing BxPc-3 human pancreatic carcinoma. Methods: Twenty four nude mice bearing tumors were injected with 0, 9.3, 18.5 and 37.0 M Bq 32P-CP-PLLA microparticle, respectively. The relative tumor growth rates were observed every day, and white blood cells, platelets and body weight were measured. At 14 d after administration, the tumors were removed, histological examination and immunohistochemical analysis were performed. Results: The relative tumor growth rates of each treatment group was lower than 40%. Histological examination showed the degenerative necrosis at the site nearby the microparticle. Immunohistochemical analysis showed that the Microvessel density (MVD) and the expression of Bcl-2 in treated group were lower than those in control group.In contrast, the expression of bax in treated group were higher than those in control group. The ratio of Bcl-2/Bax protein significantly decreased in the treatment group,which were 3.83 ± 0.43, 0.47 ± 0.13, 1.10 ± 0.32, 2.19 ± 0.57 for 0, 9.3, 18.5 and 37.0 MBq 32P-CP-PLLA microparticle, respectively (t=2.36-2.77, P<0.05). MVD were 31.2 ± 2.3, 23.8 ± 1.5, 14.8 ±0.8, 11.0 ± 1.2, respectively. Dose dependence was observed in both HE and IHC staining after 14 d treatment (t=2.30-2.57, P<0.05). Conclusions: Intratumoral injection of 32P-CP-PLLA microparticle might be a safe, easy and effective radionuclide interventional therapy for pancreatic carcinoma. (authors)

  9. Advances in the treatment of pancreatic cancer. Limitations of surgery and evaluation of new therapeutic strategies

    International Nuclear Information System (INIS)

    Pancreatic ductal carcinoma is one of the most dismal malignancies of the gastrointestinal system. Even after curative resection, the actual 5-year survival is only 10%-20%. Of all the treatments used against pancreatic cancer, surgery is still the only one that can achieve complete cure. Pancreatic cancer spreads easily to the adjacent tissues and distant metastasis is common. Typically, this cancer invades the retropancreatic neural tissue, duodenum, portal vein (PV), and superior mesenteric vein (SMV), or regional lymph nodes. For this reason, aggressive surgery that removes the cancerous lesion completely is recommended. Several retrospective and prospective studies have been conducted to validate the usefulness of aggressive surgery for pancreatic cancer in the past few decades. Surprisingly, the survival benefits of aggressive surgery have been denied by most randomized controlled trials (RCTs). This implies that surgery alone is not enough. Thus, adjuvant therapy, such as radiotherapy and chemotherapy, has been given in combination with surgery to improve survival. Although the benefits of radiotherapy alone are limited, the results of chemotherapy are promising. Other newly evolving molecular targeting drugs may also improve the treatment outcomes of pancreatic cancer. (author)

    Full Text Available Isoalantolactone, a sesquiterpene lactone compound possesses antifungal, antibacteria, antihelminthic and antiproliferative activities. In the present study, we found that isoalantolactone inhibits growth and induces apoptosis in pancreatic cancer cells. Further mechanistic studies revealed that induction of apoptosis is associated with increased generation of reactive oxygen species, cardiolipin oxidation, reduced mitochondrial membrane potential, release of cytochrome c and cell cycle arrest at S phase. N-Acetyl Cysteine (NAC, a specific ROS inhibitor restored cell viability and completely blocked isoalantolactone-mediated apoptosis in PANC-1 cells indicating that ROS are involved in isoalantolactone-mediated apoptosis. Western blot study showed that isoalantolactone increased the expression of phosphorylated p38 MAPK, Bax, and cleaved caspase-3 and decreased the expression of Bcl-2 in a dose-dependent manner. No change in expression of phosphorylated p38 MAPK and Bax was found when cells were treated with isoalantolactone in the presence of NAC, indicating that activation of these proteins is directly dependent on ROS generation. The present study provides evidence for the first time that isoalantolactone induces ROS-dependent apoptosis through intrinsic pathway. Furthermore, our in vivo toxicity study demonstrated that isoalantolactone did not induce any acute or chronic toxicity in liver and kidneys of CD1 mice at dose of 100 mg/kg body weight. Therefore, isoalantolactone may be a safe chemotherapeutic candidate for the treatment of human pancreatic carcinoma.

  11. Advances in radionuclide molecular imaging of pancreatic β-cells

    International Nuclear Information System (INIS)

    In both type 1 and type 2 diabetes mellitus, β-cell mass (BCM) is lost.Various treatments are developed to restore or reconstruct BCM. The development of non-invasive methods to quantify BCM in vivo offers the potential for early detection of β-cell dysfunction prior to the clinical onset of diabetes. PET imaging with radioligands that directly target the pancreatic β-cells appears promising. The ability to determine the BCM has been investigated in several targets and their corresponding radiotracers, including radiolabeled receptor ligands, antibodies, metabolites and reporter genes. Therefore, we summarize the recent progress in radionuclide molecular imaging of pancreatic β-cells. (authors)

    The accumulation of immunosuppressive cells and exhausted effector T cells highlight an important immune dysfunction in advanced stage hepatocellular carcinoma (HCC) patients. These cells significantly hamper the efficacy immunotherapies and facilitate HCC progression. We have recently demonstrated that the multipronged depletion of immunosuppressive cells potentially restores effector T-cell function in HCC.

    Schmidinger, Manuela; Hejna, Michael; Zielinski, Christoph C

    2004-12-01

    Renal cell carcinoma accounts for 2-3% of all malignancies. The most common subtype [85%] is the clear cell variant. A total of 30% of patients present with metastatic disease at diagnosis and another 30-40% will develop metastases during the course of the disease. Conventional cancer treatment is not effective, but cytokines including recombinant interleukin-2 (aldesleukin) have demonstrated clinical activity of various degrees. This drug profile provides a review of the literature on studies using aldesleukin in patients with metastatic renal cell carcinoma. Aldesleukin has been used in different dose schedules applying various administration routes, as either monotherapy or in combination with other cytokines, chemotherapy, endocrine treatment and adoptive cellular immunotherapy. Although a large number of randomized trials have been performed with different treatment strategies, it still remains uncertain whether the dose or combination of aldesleukin with other agents substantially influence treatment outcome. It appears that factors other than those that are treatment related are responsible for the course of the disease. PMID:15606326

  16. Proteomic analysis of differential proteins in pancreatic carcinomas: Effects of MBD1 knock-down by stable RNA interference

    International Nuclear Information System (INIS)

    Methyl-CpG binding domain protein 1 (MBD1), a suppressor of gene transcription, may be involved in inactivation of tumor suppressor genes during tumorigenesis. Over-expression of MBD1 has been reported in human pancreatic carcinomas. In this study, we established a MBD1-knock-down pancreatic cancer cell line (BxPC-3) using stable RNA interference, to compare the proteomic changes between control and MBD1-knock-down cells using two-dimensional gel electrophoresis and mass spectrometry. We identified five proteins that were up-regulated and nine proteins that were down-regulated. Most of the identified proteins are involved in tumorigenesis, some are prognostic biomarkers for human malignant tumors. Our data suggest that these differential proteins may be associated with the function of MBD1, and provide some insight into the functional mechanism of MBD1 in the development of pancreatic cancer

  17. Phosphorylated Smad2 in Advanced Stage Gastric Carcinoma

    International Nuclear Information System (INIS)

    Transforming growth factor β (TGFβ) receptor signaling is closely associated with the invasion ability of gastric cancer cells. Although Smad signal is a critical integrator of TGFβ receptor signaling transduction systems, not much is known about the role of Smad2 expression in gastric carcinoma. The aim of the current study is to clarify the role of phosphorylated Smad2 (p-Smad2) in gastric adenocarcinomas at advanced stages. Immunohistochemical staining with anti-p-Smad2 was performed on paraffin-embedded specimens from 135 patients with advanced gastric adenocarcinomas. We also evaluated the relationship between the expression levels of p-Smad2 and clinicopathologic characteristics of patients with gastric adenocarcinomas. The p-Smad2 expression level was high in 63 (47%) of 135 gastric carcinomas. The p-Smad2 expression level was significantly higher in diffuse type carcinoma (p = 0.007), tumours with peritoneal metastasis (p = 0.017), and tumours with lymph node metastasis (p = 0.047). The prognosis for p-Smad2-high patients was significantly (p = 0.035, log-rank) poorer than that of p-Smad2-low patients, while a multivariate analysis revealed that p-Smad2 expression was not an independence prognostic factor. The expression of p-Smad2 is associated with malignant phenotype and poor prognosis in patients with advanced gastric carcinoma

    Therapeutic strategies in the treatment of pancreatic carcinoma are based on the high number of non-resectable cancers, the high relative radioresistance and the high distant metastases rate. Even in curatively resected carcinomas, a locally effective treatment modality is needed because of the risk of microscopical residual disease in the peripancreatic tissue. The efficacy of radiotherapy is dose dependent. Based on an analysis of published data a dose of more than 50 Gy is recommended, resulting in a high morbidity rate with external beam radiotherapy alone. The use of intraoperative radiotherapy allows locally restricted dose escalation without increased perioperative morbidity. In adjuvant and in primary treatment, local tumor control was improved (70-90%). With palliative intent, pain relief was obtained rapidly in over 60% of patients and led to improved patient performance. As a result of the high distant metastases rate, even in curatively resected carcinomas, the overall prognosis could not be significantly improved. Further dose escalation is limited by the increasing incidence of upper gastrointestinal bleeding (20-30%). (orig.) [Deutsch] Therapiestrategien beim Pankreaskarzinom werden bestimmt durch den hohen Anteil primaer nicht resektabler Karzinome, der hohen relativen Strahlenresistenz und der hohen Fernmetastasierungsrate. Selbst kurativ resezierte Karzinome erfordern durch ihre hohe lokale Tumorzellpersistenz eine lokal effektive adjuvante Behandlungsmassnahme. Die Effektivitaet einer Radiotherapie ist dosisabhaengig. Aus der Analyse publizierter Daten wird eine Dosis von >50 Gy, welche bei der alleinigen perkutanen Bestrahlung mit einer hohen Morbiditaet verbunden ist, empfohlen. Mit der intraoperativen Radiotherapie ist eine lokal begrenzte Dosiseskalation ohne erhoehte perioperative Morbiditaet moeglich. Sowohl in der adjuvanten als auch in der primaeren Behandlung kann die lokale Tumorkontrolle deutlich verbessert werden (70-90%). Unter

    International Nuclear Information System (INIS)

    The remedy, especially chemotherapy, for advanced pancreatic cancer is hardly ever successful in terms of efficacy rate and survival period, because it is virtually unable to contribute to the improvement of median survival time (MST). Thus, we devised a new intermittent dosage regimen utilizing the cell cycle difference of normal gastrointestinal (GI) tract, bone marrow cell and pancreatic cancer cell, making use of 5-FU (→S-1), cisplatin (CDDP) and paclitaxel in March 2002. Ten patients with advanced pancreatic cancer (4 in Stage IVa and 6 in Stage IVb) were treated with this new regimen. As a result, an efficacy ratio of 50.0% and a 1-year survival ratio of 60.0% were achieved. However, 2-year survival ratio of 12.0% was low, and there was no 3-year survivor. The MST was 19 months as of December 31, 2006. All of the non-hematological toxicities were under grade 2. Eight patients had hematological toxicities over grade 3 and most of them were anemia and neutropenia. Only 2 cases had thrombocytopenia. Although adverse effects related to this regimen were clinically manageable, it was difficult to improve MST of patients with advanced pancreatic cancer with chemotherapy alone including this regimen. Hence, we devised another regimen with the joint use of radiotherapy along with the same chemotherapy regimen in January 2003. Twenty patients with advanced pancreatic cancer (Stage IV) were treated with this regimen. It is presently under way, and an efficacy ratio of 35.0%, 1-year survival ratio of 86.3% and 2-year survival ratio of 64.0% were obtained by May 2005, showing that this may contribute to the extension of survival time of Stage IV pancreatic cancer patients.

    Over the last twenty years, there is a limited number of effective cytotoxic or biological agents that managed to get approval in advanced pancreatic ductal adenocarcinoma. Despite numerous trials, investments in translational research and generally in health care, the survival of pancreatic cancer patients has improved by a few only months. This disappointing reality necessitates a better understanding of the pathogenesis of this disease and the identification of targetable alterations which might lead to development of more effective drugs or better combinations. At the 2013 Annual Meeting of the American Society of Clinical Oncology, few novel agents and new therapeutic concepts, tested in phase I studies in advanced pancreatic ductal adenocarcinoma, were presented. The first notable phase I study referred to the combination of chemotherapy with local delivery of silencing RNA against the K-ras mutation G12D, in advanced pancreatic ductal adenocarcinoma, which was well tolerated and promising (Abstract #4037). The second one referred to a combination of gemcitabine with pegylated recombinant human hyaluronidase (PEGPH20), an inhibitor of hyaluronan which as a matrix glycosaminoglycan is believed to play role in the reduced drug delivery to cancer (Abstract #4010). The other notable abstract was related to an early phase study which tested the safety and toxicity of arctigenin, a traditional herbal agent found in Arctium lappa Linné, administered as an oral formulation (GMS-01) in pancreatic ductal adenocarcinoma patient resistant to standard chemotherapy (Abstract #2559). The aforementioned early phase studies open new therapeutic approaches which deserve further testing in advanced pancreatic cancer. PMID:23846926

    Full Text Available Abstract Introduction Predictive genetic screening and regular screening programs in patients with multiple endocrine neoplasia type 1 are intended to detect and treat malignant tumors at the earliest stage possible. Malignant neuroendocrine pancreatic tumors are the most frequent cause of death in these patients. However, the extent and intervals of screening in patients with multiple endocrine neoplasia type 1 are controversial as neuroendocrine tumors are usually slow growing. Here we report the case of a patient who developed a fast-growing neuroendocrine carcinoma within 15 months of a laparoscopic distal pancreatic resection. Case presentation We followed a group of 45 patients with multiple endocrine neoplasia type 1 by an annual screening program in the Department of Visceral, Thoracic, and Vascular Surgery at the University Hospital Marburg in cooperation with the Department of Radiology and the Division of Endocrinology. A man with multiple endocrine neoplasia type 1 who was diagnosed with a recurrent primary hyperparathyroidism underwent a distal pancreatic resection for a non-functional neuroendocrine tumor. In the context of our regular screening program, a large non-functional neuroendocrine tumor was diagnosed in the pancreatic head 15 months after the first pancreatic surgery. Therefore, we performed an enucleation and regional lymph node resection. At histology, the diagnosis of a neuroendocrine carcinoma with one lymph node metastasis was established. There was no evidence of recurrence 9 months after re-operation. Conclusion Fast-growing neuroendocrine tumors are rare in patients with multiple endocrine neoplasia type 1. The intervals, both postoperative and in newly diagnosed pancreatic lesions, in patients with multiple endocrine neoplasia type 1 should be reduced to 6 months to establish the early diagnosis of rapidly progressive disease in a small subset of patients.

    International Nuclear Information System (INIS)

    Objective: to evaluate the effect of radiotherapy and joint action with CMNa and 2-DG early by uptake of 18F-FDG in human pancreatic carcinoma cell Patu 8988. Methods: The human pancreatic carcinoma cell Patu 8988 were exposed to a single fraction of X-ray radiation either with glycodidazolum natrium (CMNa) or 2-deoxy-D-glucose (2-DG) or irradiation-only. The uptake of 18F-FDG was calculated 24 and 48 h after irradiation. Results: The differences of 18F-FDG uptake between groups of various dose had no significance 24 h after irradiation (P>0.05). 18F-FDG uptake in the 2-DG groups and CMNa groups were lower than that in the irradiation-only groups (P<0.05 or <0.01). The differences of 18F-FDG uptake in 2-DG groups, CMNa groups and irradiation-only groups had significance 24 and 48 h after irradiation (P<0.05). 18F-FDG uptake decreased with the increasing dose of X-ray. Uptake was positively correlated with the A value 24 and 48 h after irradiation (r=0.759, r=0.814, P<0.01). Conclusion: The uptake of 18F-FDG with human pancreatic carcinoma cell Patu 8988 decreased 24 h after irradiation with 2-DG or CMNa. Response to radiotherapy could be predicted early by 18F-FDG PET scans. (authors)

    Full Text Available Abstract Background Our objective was to test a brief, symptom index for advanced renal cell carcinoma, a disease affecting over 38,000 Americans each year and often diagnosed in late stages. Methods We conducted secondary data analyses on patient-reported outcomes of 209 metastatic renal cell carcinoma patients participating in a Phase III clinical trial. Patient-reported outcomes, obtained from the FACT-Biological Response Modifier (FACT-BRM scale, were available at baseline, 2, and 8 weeks. We analyzed data from eight FACT-BRM items previously identified by clinical experts to represent the most important symptoms of advanced renal cell carcinoma. Items comprising this index assess nausea, pain, appetite, perceived sickness, fatigue and weakness, with higher scores indicating fewer symptoms. We determined reliability and validity of the index and estimated a minimally important difference. Results The index had excellent internal reliability at all three time points (alphas ≥ 0.83. Baseline scores were able to discriminate patients across Karnofsky performance status, number of metastatic sites, and risk group categories (ps Conclusion The 8-item index of patient-reported symptoms of renal cell carcinoma appears to be a psychometrically sound measure. It is a brief, reliable, and valid measure that can easily be adapted for use in clinical trials and observational studies.

    Objective: To identify new markers for prediction of lymph node metastasis. Methods: cDNA probes were prepared by labeling mRNA from samples of four pancreatic carcinoma tissues with Cy5-dUTP and mRNA from adjacent normal tissues with Cy3-dUTP respectively through reverse transcription. The mixed probes of each sample were then hybridized with 4,096 cDNA arrays (4,000 unique human cDNA sequences), and the fluorescent signals were scanned by ScanArray 3000 scanner (General Scanning, Inc.). The values of Cy5-dUTP and Cy3-dUTP on each spot were analyzed and calculated by ImaGene 3.0 software (BioDiscovery, Inc.). Genes that differentially expresses in each cancerous tissue were sought out according to the standard that the absolute value of natural logarithm of the ratio of Cy5 to Cy3 is greater than 0.69, i. e., more than 2 times change of gene expression, and the signal value of either Cy3 and Cy5 need to be greater than 600. Then, the genes differently expressed in cancer with and without lymphatic metastasis were screened out for further analysis. Results: Among 2 samples with lymphatic metastasis and 2 samples without metastasis, 56 genes, which accounted for 1.40% of genes on the microarray slides, exhibited differentially expression in cancerous tissues with lymphatic metastasis. There were 32 over-expressed genes including 11 having been registered in Genebank, and 24 under-expressed genes including 3 in Genebank. Conclusion: Microarray analysis may provide invaluable information to identify specific gene expression profile of lymphatic metastasis in pancreatic cancer.

    Endoscopic retrograde cholangiopancreatography (ERCP) is considered the first-approach for biliary drainage. In cases of ERCP failure, patients are usually referred for percutaneous transhepatic biliary drainage or surgical biliary bypass. In the last decade, the indications of endoscopic ultrasound (EUS) in the management of patients with pancreatic cancer have increased, and numerous cases of EUS-guided biliary drainage have been reported in patients with failures during the ERCP. Our goal is to report a patient with locally advanced pancreatic cancer who presented with painless jaundice and cholestasis with biliary and duodenal obstruction. A EUS-guided choledochoduodenostomy was performed by placement of a self-expanding metal stent. PMID:26502467

    Full Text Available Introduction. Isolated pancreatic and peripancreatic tuberculosis is a challenging diagnosis due to its rarity and variable presentation. Pancreatic tuberculosis can mimic pancreatic carcinoma. Similarly, autoimmune pancreatitis can appear as a focal lesion resembling pancreatic malignancy. Endoscopic ultrasound-guided fine needle aspiration provides an effective tool for differentiating between benign and malignant pancreatic lesions. The immune processes involved in immunoglobulin G4 related systemic diseases and tuberculosis appear to have some similarities. Case Report. We report a case of a 59-year-old Southeast Asian male who presented with fever, weight loss, and obstructive jaundice. CT scan revealed pancreatic mass and enlarged peripancreatic lymph nodes. Endoscopic ultrasound-guided fine needle aspiration confirmed the presence of mycobacterium tuberculosis. Patient also had high immunoglobulin G4 levels suggestive of autoimmune pancreatitis. He was started on antituberculosis medications and steroids. Clinically, he responded to treatment. Follow-up imaging showed findings suggestive of chronic pancreatitis. Discussion. Pancreatic tuberculosis and autoimmune pancreatitis can mimic pancreatic malignancy. Accurate diagnosis is imperative as unnecessary surgical intervention can be avoided. Endoscopic ultrasound-guided fine needle aspiration seems to be the diagnostic test of choice for pancreatic masses. Long-term follow-up is warranted in cases of chronic pancreatitis.

  11. Prenyltransferase inhibitor radiosensitization of pancreatic ductal carcinoma (PaCa) cells

    International Nuclear Information System (INIS)

    Farnesyltransferase inhibitors (FTIs) radiosensitize tumor cell lines expressing activated H-Ras. K-Ras however remains active after FTI treatment due to prenylation by geranylgeranyltransferase. Up to 90% of pancreatic carcinomas (PaCa) are mutant in K-ras. We hypothesized that combined FTI and geranylgeranyltransferase inhibitor (GGTI) treatment could radiosensitize PaCa cells. Nine human PaCa lines (7 K-ras-mutant, 2 ras-wt) and transgenic mouse pancreatic ductal cells (PDC) expressing wt-ras or mutant K-ras were tested in clonogenic assays with combined FTI-A +/- GGTI-B (Merck and Co Inc.). Inhibition of PI3- kinase (with LY294002) or inhibition of MEK1/2 (with U0126) served to assess the significance of the PI3-kinase and MAPK to radiation survival in these cells. H- and K-Ras prenylation status and changes in phosphorylation of AKT and MAPK were monitored as were changes in cell cycle distribution. FTI+GGTI treatment achieved inhibition of K-Ras prenylation in all PaCa cell lines. This treatment radiosensitized the K-ras mutant cell lines AsPC-1, Capan-2, MiaPaCa-2 and PSN-1, PancM, but not Capan-1 or the ras-wt cell lines (BxPC-3, HS766T, PDC-wt). L-778,123, a dual action inhibitor, sensitized all K-ras mutant cells. Surprisingly, PancM, Panc-1, MiaPaCa-2 and PDC K-Ras cells were radiosensitized by FTI treatment alone. R11577, another FTI without GGTI activity, also sensitized Panc-1 and MiaPaCa-2 and additionally AsPC-1 cells. Radiosensitization was also achieved after treatment with LY294002 in all PaCa lines expressing mutant-K-ras and the ras-wt line BxPC-3 overexpressing Akt2. However these lines were not sensitized by U0126. FTI+GGTI sensitize K-ras mt PaCa cell lines to radiation. PI3-kinase signaling but not MAPK signaling appears to contribute to radiation survival in PaCa cells. Radiosensitization of certain PaCa cells by FTI alone indicates that alternate pathways or farnesylated targets other than K-Ras may also be involved in radiation survival

    AIM: To study the effects of chromic-P32 phosphate (32p colloids) interstitial administration in Pc-3 implanted pancreatic carcinoma, and investigate its anticancer mechanism.METHODS: Ninety-eight tumor bearing nude mice werekilled at different time points after the injection of 32Pcolloids to the tumor core with observed radioactivity. The light microscopy, transmission electron microscopy (TEM) and immuno-histochemistry and flow cytometry were used to study the rates of tumor cell necrosis, proliferating cell nuclear antigen index, the micro vessel density (MVD). The changes of the biological response to the lymphatic transported 32p colloids in the inguinal lymph node (ILN) were dynamically observed, and the percentage of tumor cell apoptosis, and Apo2.7, caspase-3, Bcl-2, Baxrelated gene expression were observed too.RESULTS: The half-life of effective medication is 13 dafter injection of 32P colloids to the tumor stroma, in 1-6groups, the tumor cell necrosis rates were 20%, 45%,65%, 70%, 95% and 4%, respectively (F= 4.14-105.36, P<0.01). MVD were 38.5±4.0, 28.0±2.9, 17.0±2.9, 8.8±1.5,5.7±2.3 and 65.0±5.2 (t= 11.9-26.1, P<0.01), respectively.Under TEM fairly differentiated Pc-3 cells were found. Thirty days after medication, tumors were shrunk and dried with scabs detached, and those in control group increased in size prominently with plenty of hypodermic blood vessels. In all animals the ILN were enlarged but in medicated animals they appeared later and smaller than those in control group. The extent of irradiative injury in ILN was positively correlated to the dosage of medication. Typical tumor cell apoptosis could be found under TEM inanimals with intra-tumoral injection of low dosed 32P colloids. The peak of apoptosis occurred in 2.96 MBq group and 24 h after irradiation. In the course of irradiationinduced apoptosis, the value of Bcl-2/Bax was down regulated; Apo2.7 and caspase-3 protein expression were prominently increased dose dependently

    5-fluorouracil (5-FU) is widely used in chemotherapy for gastric and colorectal cancer, but gemcitabine (GEM), and not 5-FU, is approved as a standard drug for use in pancreatic cancer. Interindividual variation in the enzyme activity of the GEM metabolic pathway can affect the extent of GEM metabolism and the efficacy of GEM chemotherapy. Human equilibrative nucleoside transporter 1 (hENT1) is recognized as a major transporter of GEM into cells. In addition, a factor that activates hENT1 is ...

    2014-11-28

    The noninvasive ablation of pancreatic cancer with high intensity focused ultrasound (HIFU) energy is received increasingly widespread interest. With rapidly temperature rise to cytotoxic levels within the focal volume of ultrasound beams, HIFU can selectively ablate a targeted lesion of the pancreas without any damage to surrounding or overlying tissues. Preliminary studies suggest that this approach is technical safe and feasible, and can be used alone or in combination with systemic chemotherapy for the treatment of patients with locally advanced pancreatic cancer. It can effectively alleviate cancer-related abdominal pain, and may confer an additional survival benefit with few significant complications. This review provides a brief overview of HIFU, describes current clinical applications, summarizes characteristics of continuous and pulsed HIFU, and discusses future applications and challenges in the treatment of pancreatic cancer.

  19. Neoadjuvant chemotherapy and radiation therapy in advanced stage nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    To assess the feasibility and the toxicity of the neoadjuvant chemotherapy on the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. We analyzed 77 previously untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with neoadjuvant chemotherapy followed by radiation therapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was as follows: AJCC stage 111-2, stage IV-75. Sixty-six patients received infusion of 5-FU (1000 mg/m2, on Day 1-5) and cisplatin (100 mg/m2, on Day 1), eleven patients received infusion of 5.FU (1000 mg/m2, on Day 1-5) and carboplatin (300 mg/m2, on Day 1) as neoadjuvant chemotherapy prior to radiation therapy. The median follow-up for surviving patients was 44 months. The overall chemotherapy response rates were 87%. The toxicities of chemotherapy were mild. Only 3 patients experienced Grade 3 toxicities (1 for cytopenia, 2 for nausea/vomiting). The degree of radiation induced mucositis was not severe, and ten patients developed Grade 2 mucositis. The 5-year overall survival rates were 68% and the 5-year disease free survival rates were 65%. The 5-year freedom from distant metastasis rates were 82% and 5-year locoregional control rates were 75%. This single institution experience suggests that neoadjuvant chemotherapy improves overall survival and disease free survival for patients with advanced stage nasopharyngeal carcinoma without increase of toxicity

    Epidermal growth factor-like domain 7 (EGFL7), also known as vascular endothelial stain, was firstly identified as a modulator of smooth muscle cell migration. Though the expression of EGFL7 was reported to be up-regulated during tumorigenesis, the clinical and biological functions of EGFL7 in pancreatic carcinoma (PC) were still not fully elucidated. In this study, we found that the serum EGFL7 level in PC tissues was statistically higher than that in normal subjects (p0.05), whereas inhibition of EGFL7 expression could decrease PaCa-2 cell invasion (p<0.05). More interestingly, by tubular formation, Chick embryo chorioallantoic membrane (CAM) and ELISA assays, our results revealed that silencing EGFL7 expression represented a strong inhibiting effect on tubular formation of micro-vessels through down-regulating the protein levels of VEGF and Ang-2 (p<0.05). Our results raised the possibility of using EGFL7as a potential prognostic biomarker and therapy target of PC, and down-regulation of EGFL7 might be considered to be a potentially important molecular treatment strategy for patients with PC.

  1. Comparative therapeutic trial of radiation with or without chemotherapy in pancreatic carcinoma

    Energy Technology Data Exchange (ETDEWEB)

    1979-09-01

    Two hundred and twenty-eight patients with carcinoma of the pancreas confined to the pancreas and peripancreatic area were randomly allocated to receive either radiation therapy alone to a dose of 6000 rad or radiation therapy delivered in conjunction with 5-fluorouracil (FU). Fluorouracil was administered concomitant with the first three days of 2000 rad increments of the radiation therapy and continued weekly indefinitely. The median survival of patients receiving radiation alone was 17.8 weeks compared to 35 weeks for patients receiving chemotherapy in conjunction with radiation (p < 0.001). Within the group receiving concomitant chemotherapy, two dose levels of radiation were evaluated by random assignment: 4000 vs 6000 rad. The superiority of 6000 rad plus 5-FU over 4000 rad plus 5-FU was established by median survival analysis, 39 weeks compared to 31 weeks and by time to progression, 31 weeks vs 22 weeks (p < 0.09). The survival curves of the 4000 and the 6000 rad arm intercepted by approximately week 60 such that there was essentially no difference in the fraction of patients surviving beyond one year. Thus, the addition of chemotherapy to radiation for pancreatic cancer potentiates the therapeutic effect and promotes longer survival. The importance of radiation dose to the therapeutic benefit can be detected in median survival but is not sustained beyond one year.

    Cultured human pancreatic carcinoma cells (MIA PaCa-2) have been shown previously to be very sensitive to E. coli L-asparaginase (EC II). The present studies have demonstrated that another enzyme, Acinetobacter glutaminase-asparaginase (AGA) is much more effective in inhibiting cell growth. At the concentration of 0.0025 U/ml of AGA activity the enzyme totally inhibited cell growth, whereas the EC II with the same concentration did not show any effect. The inhibition of cell growth correlated well with inhibition of protein and glycoprotein synthesis. The addition of L-glutamine at the concentration of 1 mM completely reversed the inhibition of protein synthesis. Similarly, the addition of L-glutamine at the concentration of 3 mM daily on 3 successive days after adding AGA resulted in significant reversal of growth inhibition. The results of this study indicate that the action of AGA on MIA PaCa-2 is, to a great extent, exerted through its L-glutaminase activity. PMID:7173949

    Background The aim of this meta-analysis was to compare the long-term survival, mortality, morbidity and the operation-related events in patients with periampullary and pancreatic carcinoma undergoing pylorus-preserving pancreaticoduodenectomy (PPPD) and pylorus-resecting pancreaticoduodenectomy (PRPD). Method A systematic search of literature databases (Cochrane Library, PubMed, EMBASE and Web of Science) was performed to identify studies. Outcome measures comparing PPPD versus PRPD for periampullary and pancreatic carcinoma were long-term survival, mortality, morbidity (overall morbidity, delayed gastric emptying [DGE], pancreatic fistula, wound infection, postoperative bleeding, biliary leakage, ascites and gastroenterostomy leakage) and operation related events (hospital stays, operating time, intraoperative blood loss and red blood cell transfusions). Results Eight randomized controlled trials (RCTs) including 622 patients were identified and included in the analysis. Among these patients, it revealed no difference in long-term survival between the PPPD and PRPD groups (HR = 0.23, p = 0.11). There was a lower rate of DGE (RR = 2.35, p = 0.04, 95% CI, 1.06–5.21) with PRPD. Mortality, overall morbidity, pancreatic fistula, wound infection, postoperative bleeding, biliary leakage, ascites and gastroenterostomy leakage were not significantly different between the groups. PPPDs were performed more quickly than PRPDs (WMD = 53.25 minutes, p = 0.01, 95% CI, 12.53–93.97); and there was less estimated intraoperative blood loss (WMD = 365.21 ml, p = 0.006, 95% CI, 102.71–627.71) and fewer red blood cell transfusions (WMD = 0.29 U, p = 0.003, 95% CI, 0.10–0.48) in patients undergoing PPPD. The hospital stays showed no significant difference. Conclusions PPPD had advantages over PRPD in operating time, intraoperative blood loss and red blood cell transfusions, but had a significantly higher rate of DGE for periampullary and

    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.

    Highlights: • PMAb83, a human monoclonal antibody against PAUF, impaired tumor progression in vivo. • PMAb83 attenuated aggressiveness of tumor cells and suppressed angiogenesis. • PMAb83 in combination with gemcitabine conferred improved survival of mouse model. - Abstract: Pancreatic adenocarcinoma up-regulated factor (PAUF) is expressed in pancreatic ductal adenocarcinoma (PDAC) and plays an important role in tumor progression and metastasis. Here we evaluate the anti-tumor efficacy of a human monoclonal antibody against PAUF, PMAb83, to provide a therapeutic intervention to treat the disease. PMAb83 reduced tumor growth and distant metastasis in orthotopically xenografted mice of human PDAC cells. PMAb83 treatment retarded proliferation along with weakened aggressiveness traits of the carcinoma cells. AKT/β-catenin signaling played a role in the carcinoma cell proliferation and the treated xenograft tumors exhibited reduced levels of β-catenin and cyclin D1. Moreover PMAb83 abrogated the PAUF-induced angiogenic responses of endothelial cells, reducing the density of CD31+ vessels in the treated tumors. In combination with gemcitabine, PMAb83 conferred enhanced survival of xenografted mice by about twofold compared to gemcitabine alone. Taken together, our findings show that PMAb83 treatment decreases the aggressiveness of carcinoma cells and suppresses tumor vascularization, which culminates in mitigated tumor growth and metastasis with improved survival in PDAC mouse models

    Gemcitabine has been demonstrated to be a potentradiosensitizer in the laboratory and in the clinic (1-7)and has proven clinical systemic activity to pancreaticcancer. Responses to systemic gemcitabine inpatients with metastatic pancreatic adenocarcinomahave been documented in phase I, phase II, and phaseIII clinical settings (8,9). Moreover, a recent randomizedtrial of gemcitabine vs 5-FU as first-linetherapy in patients with advanced pancreatic adenocarcinomademonstrated a modest median survivalbenefit (4.41 vs 5.65 mo,p= 0.0025) for those patientswho received gemcitabine compared to those whoreceived 5-FU (10). In addition, gemcitabine wasshown to improve cancer-related symptoms and performancestatus as assessed by a quantitative clinicalbenefit scale in both untreated and previouslytreated patients with metastatic adenocarcinoma ofthe pancreas (10,11). Based on these data, the FDAapproved gemcitabine as a first-line agent for patientswith advanced adenocarcinoma of the pancreas. PMID:12754400

    Isabelle Van Seuningen

    2010-10-01

    Full Text Available Pancreatic cancer is characterized by an often dramatic outcome (five year survival < 5% related to a late diagnosis and a lack of efficient therapy. Therefore, clinicians desperately need new biomarkers and new therapeutic tools to develop new efficient therapies. Mucins belong to an ever increasing family of O-glycoproteins. Secreted mucins are the main component of mucus protecting the epithelia whereas membrane-bound mucins are thought to play important biological roles in cell-cell and cell-matrix interactions, in cell signaling and in modulating biological properties of cancer cells. In this review, we will focus on the altered expression pattern of mucins in pancreatic cancer, from the early neoplastic lesion Pancreatic Intraepithelial Neoplasia (PanIN to invasive pancreatic carcinomas, and the molecular mechanisms (including genetic and epigenetic regulation and signaling pathways known to control their expression. Moreover, we will discuss the recent advances about the biology of both secreted and membrane-bound mucins and their key roles in pancreatic carcinogenesis and resistance to therapy. Finally, we will discuss exciting opportunities that mucins offer as potential therapeutic targets in pancreatic cancer.

  15. Comparison of capecitabine and 5-fluorouracil in chemoradiotherapy for locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Although capecitabine has theoretical advantages in the pharmacokinetics, such as higher intratumoral and lower systemic concentration, relative to bolus 5-fluorouracil (5-FU), outcomes of chemoradiotherapy (CRT) with capecitabine or bolus 5-FU have not been directly compared in patients with locally advanced pancreatic cancer. Therefore, we retrospectively compared the outcomes, including toxicity, tumor response, and overall survival, of oral capecitabine plus radiotherapy (RT) with bolus 5-FU plus RT, in patients with locally advanced pancreatic cancer. Between August 2006 and January 2012, 98 patients with locally advanced pancreatic cancer received CRT, with 52 receiving concurrent oral capecitabine and 46 receiving bolus injection of 5-FU. Primary tumor and overall response after CRT were evaluated radiologically, and toxicity, tumor response, and overall survival (OS) were compared in the two groups. Baseline clinical parameters of the two groups were similar. The rates of ≥ Grade 3 hematologic (0% vs. 8.7%, p = 0.045) and non-hematologic (0% vs. 8.7%, p = 0.045) toxicities were significantly lower in the capecitabine group than in the 5-FU group. Primary tumor (30.7% vs. 28.2%, p = 0.658) and overall (13.7% vs. 15.2%, p = 0.273) response rates and median OS time (12.5 months vs. 11.6 months, p = 0.655) were similar in the two groups. Capecitabine plus RT may be a safe and feasible regimen for patients with locally advanced pancreatic cancer, with similar efficacy and low rates of toxicities compared with bolus 5-FU plus RT

    We wanted to evaluate the levels of effect and safety of high-intensity focused ultrasound ablation (HIFU) for treating patients with advanced pancreatic cancer. Nineteen sessions of HIFU, with the patients under general anesthesia, were performed in 18 patients with advanced pancreatic cancer. The change of the gray-scale of the target lesion was analyzed during HIFU, and MRI was performed before and after HIFU. We assessed the extent of coagulative necorsis, the change of pain and the complications after HIFU. The change of tumor size and the survival of patients were also evaluated. The average size of tumor was 4 cm in diameter. Eighty nine percent of the target tumors showed increased echogenicity. On MRI, necrosis of the entire target tumor occurred in 79% of the patients. After treatment, effective pain relief was noted in 89% of the patients. There were no major complications. No size increase of the treated tumor was noted during 24 weeks of follow-up for 10 patients. Six patients among 12 patients who were available for follow-up are still alive and they are receiving chemotherapy. Six patients expired due to other disease or progression of metastasis. HIFU is a safe method without any major complications, and it is effective for inducing tumor necrosis and achieving pain control for patients with advanced pancreatic cancer.

    Full Text Available The majority of pancreatic cancer diagnoses are made at the advanced stage and when metastasis has already occurred, and the 1- and 5-year survival rates are extremely low. Cemcitabine remains the most frequently applied treatment option, yet the most effective chemotherapeutic agents and combinations with multiple agents and/or radiotherapy only marginally improve patient survival and may even establish an environment conducive to cancer cells with stem cell-like characteristics. An alternative treatment modality, cryoablation, is available and has been applied at our institute to patients with unresectable pancreatic cancer since 2001. In this article, we present our collective experience with patient outcome using cryoablation, alone or combined with other treatment modalities such as brachytherapy (125iodine seed implantation. The overall outcomes have been encouraging, suggesting that comprehensive therapy including cryoablation may prolong the survival of patients with advanced or metastatic pancreatic cancer, and we are achieving particular success with a novel combination of percutaneous cryoablation, cancer microvascular intervention with 125iodine seed implantation, and combined immunotherapy (3C applied using an individualized patient strategy (P. The 1- through 10-year survival rates of 145 patients treated with the so-called “3C+P model” are presented in support of this new strategy as a promising new treatment for advanced and metastatic cancer

    A 68-year-old female visited a local clinic with epigastralgia. A routine laboratory test revealed jaundice and liver dysfunction. She was referred to this hospital. Abdominal computed tomography (CT) and endoscopic retrograde cholangio-pancreatography (ERCP) revealed that the density of the entire pancreas had decreased, and showed dilatation of the common bile duct (CBD) and the main pancreatic duct (MPD). Pancreatic cancer was diagnosed by cytological examination analyzing the pancreatic juice obtained by ERCP. When jaundice had decreased the tumor was observed via laparotomy. No ascites, liver metastasis, or peritoneal dissemination was observed. The entire pancreas was a hard mass, and a needle biopsy was obtained from the head, body and tail of the pancreas. These biopsies diagnosed a poorly differentiated adenocarcinoma. Hepaticojejunostomy was thus performed, and postoperative progress was good. Chemotherapy with 1000 mg/body per week of gemcitabine was administered beginning 15 d postoperatively. However, the patient suffered relatively severe side effects, and it was necessary to change the dosing schedule of gemcitabine. Abdominal CT revealed a complete response (CR) after 3 treatments. Therefore, weekly chemotherapy was stopped and was changed to monthly administration. To date, for 4 years after chemotherapy, the tumor has not reappeared.Key werds: Gemcitabine; Long-term survival; Unresectable advanced pancreatic cancer

    The study results of non randomized radio chemotherapy in the cervix cancer treatment are cheering and clinically the answers are faster. However only some randomized studies using hydroxyurea showed a benefit in survival term. The association tolerance of 5 FU with cisplatin is generally acceptable but we don't know yet the long-range toxicity. Finally we'll have to determine in which quantity, the pelvis control improvement should be able to increase the survival rate, because the metastases are frequent in these carcinoma advanced forms. 59 refs., 2 tabs

Once the tumor has spread beyond the margins of the pancreas, chemotherapy is the major treatment modality offered to patients; however, chemotherapy does not significantly improve survival.Objective: Opioid growth factor (OGF; [Met5]-enkephalin is a natural peptide that has been shown to inhibit growth of pancreatic cancer in cell culture and in nude mice. The purpose of this study was to evaluate the effects of OGF biotherapy on subjects with advanced pancreatic cancer who failed chemotherapy.Methods: In a prospective phase II open-labeled clinical trial, 24 subjects who failed standard chemotherapy for advanced pancreatic cancer were treated weekly with OGF 250 μg/kg intravenously. Outcomes measured included clinical benefit, tumor response by radiographic imaging, quality of life, and survival.Results: Clinical benefit response was experienced by 53% of OGF-treated patients compared to historical controls of 23.8% and 4.8% for gemcitabine and 5-fluorouracil (5-FU, respectively. Of the subjects surviving more than eight weeks, 62% showed either a decrease or stabilization in tumor size by computed tomography. The median survival time for OGF-treated patients was three times that of untreated patients (65.5 versus 21 days, p < 0.001. No adverse effects on hematologic or chemistry parameters were noted, and quality of life surveys suggested improvement with OGF. Limitations: Measurements other than survival were not allowed in control patients, and clinical benefit comparisons were made to historical controls.Conclusion: OGF biotherapy improves the

    Full Text Available Nitric oxide-releasing aspirin (NO-aspirin represents a novel class of promising chemopreventive agents. Unlike conventional nonsteroidal anti-inflammatory drugs, NO-aspirin seems to be free of adverse effects while retaining the beneficial activities of its parent compound. The effect of NO-aspirin on pancreatic carcinogenesis was investigated by assessing the development of precursor pancreatic lesions and adenocarcinomas in KrasG12D/+ transgenic mice that recapitulate human pancreatic cancer progression. Six-week-old male p48Cre/+-LSL-KrasG12D/+ transgenic mice (20 per group were fed diets containing 0, 1000, or 2000 ppm NO-aspirin. The development of pancreatic tumors was monitored by positron emission tomography imaging. All mice were killed at the age of 41 weeks and assessed for pancreatic intraepithelial neoplasia (PanIN and pancreatic ductal adenocarcinoma (PDAC and for molecular changes in the tumors. Our results reveal that NO-aspirin at 1000 and 2000 ppm significantly suppressed pancreatic tumor weights, PDAC incidence, and carcinoma in situ (PanIN-3 lesions. The degree of inhibition of PanIN-3 and carcinoma was more pronounced with NO-aspirin at 1000 ppm (58.8% and 48%, respectively than with 2000 ppm (47% and 20%, respectively. NO-aspirin at 1000 ppm significantly inhibited the spread of carcinoma in the pancreas (∼97%; P < .0001. Decreased expression of cyclooxygenase (COX; with ∼42% inhibition of total COX activity, inducible nitric oxide synthase, proliferating cell nuclear antigen, Bcl-2, cyclin D1, and β-catenin was observed, with induction of p21, p38, and p53 in the pancreas of NO-aspirin-treated mice. These results suggest that low-dose NO-aspirin possesses inhibitory activity against pancreatic carcinogenesis by modulating multiple molecular targets.

  7. Hepatic Arterial Infusion Chemotherapy for Advanced Hepatocellular Carcinoma in Japan

    International Nuclear Information System (INIS)

    Transcatheter methods such as transcatheter arterial chemoembolization (TACE) and hepatic arterial infusion chemotherapy (HAIC) have an important role in the treatment for advanced hepatocellular carcinoma (HCC). Recently, sorafenib, an inhibitor of tyrosine kinases, has been found to obtain survival benefits in patients with HCC, leading to major advances in the treatment of advanced HCC. However, it is associated with a low tumor response rate, minimal survival advantage, and high rates of adverse events. On the other hand, high rates of objective treatment response with HAIC for advanced HCC have been reported, although convincing evidence of it contributing to overall survival in HAIC has been lacking. In Japan, HAIC still tends to be the preferred method for the treatment of advanced HCC, even in patients with poor liver function. However, the choice of chemotherapeutic agents in TACE/HAIC for HCC varies between institutions. In this review, based on studies reported to date in the literature, we refer to current knowledge regarding the chemotherapeutic agents used for TACE/HAIC for HCC in Japan and consider the future perspectives for HAIC for this cancer

    International Nuclear Information System (INIS)

    Objective: To improve the therapeutic response and survival of locally advanced pancreatic cancer treated with radiochemotherapy. Methods: Fifty-nine patients with stage II-III pancreatic cancer were divided into two groups: 33 patients were treated with three-dimensional conformed radiotherapy (3DCRT) plus regional intra-arterial infusion chemotherapy (CT) and 26 patients received 3DCRT alone. Results: The response (pain-alleviating) rates were 78.8% in 3DCRT + CT group and 80.8% in 3DCRT group, while the overall response (CR + PR) rates were 78.8% and 42.3% (P < 0.01), respectively. The 1-, 2-, 3-year survival rates were 72.2%, 48.5%, 9.1% and 50.0%, 15.4%, 3.9%, with the difference in the 2-year survival between these two groups statistically significant (P < 0.01). Conclusions: Three dimensional conformal radiation therapy combined with regional intra-arterial infusion chemotherapy is an effective treatment for unresectable locally advanced pancreatic cancer

    Full Text Available BACKGROUD: There is substantial evidence that infection with Helicobacter pylori plays a role in the development of gastric cancer and that it is rarely found in gastric biopsy of atrophic gastritis and gastric cancer. On advanced gastric tumors, the bacteria can be lost from the stomach. AIMS: To analyze the hypothesis that the prevalence of H.pylori in operated advanced gastric carcinomas and adjacent non-tumor tissues is high, comparing intestinal and diffuse tumors according to Lauren's classification METHODS: A prospective controlled study enrolled 56 patients from "Hospital Universitário", Federal University of Rio Grande do Norte, Natal, RN, Brazil, with advanced gastric cancer, treated from February 2000 to March 2003. Immediately after partial gastrectomy, the resected stomach was opened and several mucosal biopsy samples were taken from the gastric tumor and from the adjacent mucosa within 4 cm distance from the tumor margin. Tissue sections were stained with hematoxylin and eosin. Lauren's classification for gastric cancer was used, to analyse the prevalence of H. pylori in intestinal or diffuse carcinomas assessed by the urease rapid test, IgG by ELISA and Giemsa staining. H. pylori infected patients were treated with omeprazole, clarithromycin and amoxicillin for 7 days. Follow-up endoscopy and serology were performed 6 months after treatment to determine successful eradication of H. pylori in non-tumor tissue. Thereafter, follow-up endoscopies were scheduled annually. Chi-square and MacNemar tests with 0.05 significance were used. RESULTS: Thirty-four tumors (60.7% were intestinal-type and 22 (39.3% diffuse type carcinomas. In adjacent non-tumor gastric mucosa, chronic gastritis were found in 53 cases (94.6% and atrophic mucosa in 36 patients (64.3%. All the patients with atrophic mucosa were H. pylori positive. When examined by Giemsa and urease test, H. pylori positive rate in tumor tissue of intestinal type carcinomas was

    The purpose of our study was to evaluate multislice computed tomography (MSCT) in the assessment of patients with clinical, laboratory, and US suspicion of pancreatic neoplasm, and to evaluate resectability status. Forty-six patients with a suspected pancreatic tumor underwent MSCT. After a preliminary precontrast survey, a postcontrast scan was performed in the arterial and portal venous phase with the following protocol: 4 x 1-mm collimation; 1.25- and 5-mm slice thickness width, respectively, and 1- and 5-mm reconstruction interval. In all patients pathological correlation was obtained. The evaluation of all images provided a diagnosis in 44 patients, with a sensitivity, specificity, and accuracy of 97, 80, and 96%, respectively. The MSCT correctly provided a diagnosis of unresectability with sensitivity of 96%, specificity of 86%, and accuracy of 93%. Evaluation of 1-mm slices demonstrated 83 of the 91 liver metastases found at surgery; conversely, the 5-mm slices detected only 76 of these lesions. Infiltration of peripancreatic major vessels was demonstrated, and was confirmed at surgery in 18 patients. High-resolution MSCT improves prediction of resectability in patients with suspected pancreatic carcinoma. Parenchymal and vascular information can be achieved with a single MSCT examination.

    Purpose: The aim of this trial was to evaluate the efficacy and toxicity of S-1 and concurrent radiation therapy for locally advanced pancreatic cancer (PC). Methods and Materials: Locally advanced PC patients with histologically or cytologically confirmed adenocarcinoma or adenosquamous carcinoma, who had no previous therapy were enrolled. Radiation therapy was delivered through 3 or more fields at a total dose of 50.4 Gy in 28 fractions over 5.5 weeks. S-1 was administered orally at a dose of 80 mg/m{sup 2} twice daily on the day of irradiation during radiation therapy. After a 2- to 8-week break, patients received a maintenance dose of S-1 (80 mg/m{sup 2}/day for 28 consecutive days, followed by a 14-day rest period) was then administered until the appearance of disease progression or unacceptable toxicity. The primary efficacy endpoint was survival, and the secondary efficacy endpoints were progression-free survival, response rate, and serum carbohydrate antigen 19-9 (CA19-9) response; the safety endpoint was toxicity. Results: Of the 60 evaluable patients, 16 patients achieved a partial response (27%; 95% confidence interval [CI], 16%-40%). The median progression-free survival period, overall survival period, and 1-year survival rate of the evaluable patients were 9.7 months (95% CI, 6.9-11.6 months), 16.2 months (95% CI, 13.5-21.3 months), and 72% (95%CI, 59%-82%), respectively. Of the 42 patients with a pretreatment serum CA19-9 level of {>=}100 U/ml, 34 (81%) patients showed a decrease of greater than 50%. Leukopenia (6 patients, 10%) and anorexia (4 patients, 7%) were the major grade 3-4 toxicities with chemoradiation therapy. Conclusions: The effect of S-1 with concurrent radiation therapy in patients with locally advanced PC was found to be very favorable, with only mild toxicity.

    2011-12-01

    Full Text Available Temsirolimus is a novel inhibitor of mammalian target of rapamycin (mTOR, which is a central regulator of the response of tumour cells to growth and survival signals. When heavily pretreated patients with advanced solid tumours received intravenous (IV temsirolimus over a broad dose range, antitumour activity was observed in various tumour types, including advanced renal cell carcinoma (RCC. A study of singleagent temsirolimus in patients with cytokine-refractory metastatic RCC subsequently demonstrated antitumour activity and encouraging progression- free survival and overall survival. Temsirolimus was generally well tolerated over the 3 dose levels tested (25 mg, 75 mg or 250 mg weekly as a 30-minute IV infusion. The most frequent grade 3 or 4 treatment-related adverse events reported (n=110 were hyperglycemia (17%, hypophosphatemia (13%, anemia (9%, and hypertriglyceridemia (6%. Results from a randomized phase III study that enrolled previously untreated patients with advanced RCC and poor-prognostic features have recently demonstrated a significant increase in overall survival (p=0.0089 for patients who received temsirolimus 25 mg IV, 30-minute infusion once weekly compared with those who received interferon-alpha up to 18 million units subcutaneously thrice weekly. On the basis of improved survival, temsirolimus can be considered a first-line treatment for patients with advanced RCC.

    Full Text Available Abstract Background Patients with advanced ovarian cancer should be treated by radical debulking surgery aiming at complete tumor resection. Unfortunately about 70% of the patients present with advanced disease, when optimal debulking can not be obtained, and therefore these patients gain little benefit from surgery. Neoadjuvant chemotherapy (NACT has been proposed as a novel therapeutic approach in such cases. In this study, we report our results with primary surgery or neoadjuvant chemotherapy as treatment modalities in the specific indication of operable patients with advanced ovarian carcinoma (no medical contraindication to debulking surgery. Patients and methods A total of 59 patients with stage III or IV epithelial ovarian carcinomas were evaluated between 1998 and 2003. All patients were submitted to surgical exploration aiming to evaluate tumor resectability. Neoadjuvant chemotherapy was given (in 27 patients where optimal cytoreduction was not feasible. Conversely primary debulking surgery was performed when we considered that optimal cytoreduction could be achieved by the standard surgery (32 patients. Results Optimal cytoreduction was higher in the NACT group (72.2% than the conventional group (62.4%, though not statistically significant (P = 0.5. More important was the finding that parameters of surgical aggressiveness (blood loss rates, ICU stay and total hospital stay were significantly lower in NACT group than the conventional group. The median overall survival time was 28 months in the conventional group and 25 months in NACT group with a P value of 0.5. The median disease free survival was 19 months in the conventional group and 21 months in NACT group (P = 0.4. In multivariate analysis, the pathologic type and degree of debulking were found to affect the disease free survival significantly. Overall survival was not affected by any of the study parameters.

    In spite of continuous research efforts directed at early detection and treatment of pancreatic cancer, the outlook for patients affected by the disease remains dismal. With most cases still being diagnosed at advanced stages, no improvement in survival prognosis is achieved with current diagnostic imaging approaches. In the absence of a dominant precancerous condition, several risk factors have been identified including family history, chronic pancreatitis, smoking, diabetes mellitus, as well as certain genetic disorders such as hereditary pancreatitis, cystic fibrosis, familial atypical multiple Most pancreatic carcinomas, however, remain sporadic. Current progress in experimental molecular techniques has enabled detailed understanding of the molecular processes of pancreatic cancer development. According to the latest information, malignant pancreatic transformation involves multiple oncogenes and tumor-suppressor genes that are involved in a variety of signaling pathways. The most characteristic aberrations (somatic point mutations and allelic losses) affect oncogenes and tumor-suppressor genes within RAS, AKT and Wnt signaling, and have a key role in transcription and proliferation, as well as systems that regulate the cell cycle (SMAD/DPC, CDKN2A/p16) and apoptosis (TP53). Understanding of the underlying molecular mechanisms should promote development of new methodology for early diagnosis and facilitate improvement in current approaches for pancreatic cancer treatment.

    Tuberculosis of the pancreas is extremely rare and in most of the cases mimics pancreatic carcinoma. There are a number of case reports on pancreatic tuberculosis with various different presentations, but only a few case series have been published, and most of our knowledge about this disease comes from individual case reports. Patients of pancreatic tuberculosis may remain asymptomatic initially and manifest as an abscess or a mass involving local lymph nodes and usually present with non-specific features. Pancreatic tuberculosis may present with a wide range of imaging findings. It is difficult to diagnose tuberculosis of pancreas on imaging studies as they may present with masses, cystic lesions or abscesses and mass lesions in most of the cases mimic pancreatic carcinoma. As it is a rare entity, it cannot be recommended but suggested that pancreatic tuberculosis should be considered in cases with a large space occupying lesions associated with necrotic peripancreatic lymph nodes and constitutional symptoms. Ultrasonography/computed tomography/endosonography-guided biopsy is the recommended diagnostic technique. Most patients achieve complete cure with standard antituberculous therapy. The aims of this study are to review clinical presentation, diagnostic studies, and management of pancreatic tuberculosis and to present our experience of 5 cases of pancreatic tuberculosis.

    Full Text Available Abstract Background Cachexia, a >10% loss of body-weight, is one factor determining the poor prognosis of pancreatic cancer. Deficiency of L-Carnitine has been proposed to cause cancer cachexia. Findings We screened 152 and enrolled 72 patients suffering from advanced pancreatic cancer in a prospective, multi-centre, placebo-controlled, randomized and double-blinded trial to receive oral L-Carnitine (4 g or placebo for 12 weeks. At entry patients reported a mean weight loss of 12 ± 2,5 (SEM kg. During treatment body-mass-index increased by 3,4 ± 1,4% under L-Carnitine and decreased (−1,5 ± 1,4% in controls (p  Conclusion While these data are preliminary and need confirmation they indicate that patients with pancreatic cancer may have a clinically relevant benefit from the inexpensive and well tolerated oral supplementation of L-Carnitine.

  1. Advanced supraglottic carcinoma: a comparative study of sequential treatment policies

    International Nuclear Information System (INIS)

    Data from 131 consecutive patients with operable stage III or IV (American Joint Committee) supraglottic carcinoma were analyzed. Based on existing treatment policies at the time of presentation, patients received either preoperative radiation therapy (RT) (48 patients), surgery alone (42 patients), or postoperative RT (41 patients). Preoperative RT dose levels were either 2000 rad in five fractions (33 patients) or 5000 rad in 25 fractions (15 patients). Postoperative RT dosages were 5000 to 6000 rad in 6 to 6 1/2 weeks. Surgical procedures included either subtotal or total laryngectomy and radical neck dissection. Tumor control was achieved in 21 of 42 patients (50%) treated with surgery alone, 23 of 48 patients (48%) treated with preoperative RT, and 29 of 41 patients (71%) treated with postoperative RT (P . 0.005). The actuarial, recurrence-free survival at 5 years was 36% and 35%, respectively, in the surgery alone or preoperative RT groups as compared to 55% in postoperatively irradiated patients. The authors conclude that advanced but resectable supraglottic carcinomas may be best treated with surgery followed by RT, rather than with surgery alone or with combined preoperative RT and surgery

  2. Efficacy and Factors Affecting Outcome of Gemcitabine Concurrent Chemoradiotherapy in Patients With Locally Advanced Pancreatic Cancer

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy and prognostic factors of gemcitabine (GEM) concurrent chemoradiotherapy (CCRT) in patients with locally advanced pancreatic cancer. Methods and Materials: Between January 2002 and December 2005, 55 patients with locally advanced pancreatic cancer treated with GEM (400 mg/m2/wk) concurrently with radiotherapy (median dose, 50.4 Gy; range, 26-61.2) at Taipei Veterans General Hospital were enrolled. GEM (1,000 mg/m2) was continued after CCRT as maintenance therapy once weekly for 3 weeks and repeated every 4 weeks. The response, survival, toxicity, and prognostic factors were evaluated. Results: With a median follow-up of 10.8 months, the 1- and 2-year survival rate was 52% and 19%, respectively. The median overall survival (OS) and median time to progression (TTP) was 12.4 and 5.9 months, respectively. The response rate was 42% (2 complete responses and 21 partial responses). The major Grade 3-4 toxicities were neutropenia (22%) and anorexia (19%). The median OS and TTP was 15.8 and 9.5 months in the GEM CCRT responders compared with 7.5 and 3.5 months in the nonresponders, respectively (both p 2/wk vs. 296 ± 15 mg/m2/wk, p = 0.02) than the nonresponders. KPS and serum carbohydrate antigen 19-9 were the most significant prognostic factors of OS and TTP. Conclusion: The results of our study have shown that GEM CCRT is effective and tolerable for patients with locally advanced pancreatic cancer. The KPS and GEM dose correlated with response. Also, the KPS and CA 19-9 level were the most important factors affecting OS and TTP

    AIM: To explore whether intensity modulated radiation therapy (IMRT) in combination with chemotherapy could increase radiation dose to gross tumor volume without severe acute radiation related toxicity by decreasing the dose to the surrounding normal tissue in patients with locally advanced pancreatic cancer.METHODS: Twenty-one patients with locally advanced pancreatic cancer were evaluated in this clinical trial,Patients would receive the dose of IMRT from 21Gy to 30Gy in 7 to 10 fractions within two weeks after conventional radiotherapy of 30Gy in 15 fractions over 3 weeks. The total escalation tumor dose would be 51, 54,57, 60Gy, respectively. 5-fluororacil (5-FU) or gemcitabine was given concurrently with radiotherapy during the treatment course.RESULTS: Sixteen patients who had completed the radiotherapy plan with doses of 51Gy (3 cases), 54Gy (3 cases), 57Gy (3 cases) and 60Gy (7 cases) were included for evaluation. The median levels of CA19-9 prior to and after radiotherapy were 716 U/ml and 255 U/ml respectively (P<0.001) in 13 patients who demonstrated high levels of CA19-9 before radiotherapy. Fourteen patients who suffered from pain could reduce at least 1/3-1/2 amount of analgesic intake and 5 among these patients got complete relief of pain. Ten patients improved in Kamofsky performance status (KPS). The median follow-up period was 8 months and one-year survival rate was 35 %. No patient suffered more than grade Ⅲ acute toxicities induced by radiotherapy.CONCLUSION: Sixty Gy in 25 fractions over 5 weeks with late course IMRT technique combined with concurrent 5-FU chemotherapy can provide a definitely palliative benefit with tolerable acute radiation related toxicity for patients with advanced pancreatic cancer.

    Image-guided tumor ablation for early stage hepatocellular carcinoma (HCC) is an accepted non-surgical treatment that provides excellent local tumor control and favorable survival benefit. This review summarizes the recent advances in tumor ablation for HCC. Diagnostic imaging and molecular biology of HCC has recently undergone marked improvements. Second-generation ultrasonography (US) contrast agents, new computed tomography (CT) techniques, and liver-specific contrast agents for magnetic resonance imaging (MRI) have enabled the early detection of smaller and inconspicuous HCC lesions. Various imaging-guidance tools that incorporate imaging-fusion between real-time US and CT/MRI, that are now common for percutaneous tumor ablation, have increased operator confidence in the accurate targeting of technically difficult tumors. In addition to radiofrequency ablation (RFA), various therapeutic modalities including microwave ablation, irreversible electroporation, and high-intensity focused ultrasound ablation have attracted attention as alternative energy sources for effective locoregional treatment of HCC. In addition, combined treatment with RFA and chemoembolization or molecular agents may be able to overcome the limitation of advanced or large tumors. Finally, understanding of the biological mechanisms and advances in therapy associated with tumor ablation will be important for successful tumor control. All these advances in tumor ablation for HCC will result in significant improvement in the prognosis of HCC patients. In this review, we primarily focus on recent advances in molecular tumor biology, diagnosis, imaging-guidance tools, and therapeutic modalities, and refer to the current status and future perspectives for tumor ablation for HCC.

  5. SBRT in unresectable advanced pancreatic cancer: preliminary results of a mono-institutional experience

    International Nuclear Information System (INIS)

    To assess the efficacy and safety of stereotactic body radiotherapy (SBRT) in patients with either unresectable locally advanced pancreatic adenocarcinoma or by locally recurrent disease after surgery. Between January 2010 and October 2011, 30 patients with unresectable or recurrent pancreatic adenocarcinoma underwent exclusive SBRT. Twenty-one patients (70%) presented with unresectable locally advanced disease and 9 patients (30%) showed local recurrence after surgery. No patients had metastatic disease. Gemcitabine-based chemotherapy was administered to all patients before SBRT. Prescription dose was 45Gy in 6 daily fractions of 7.5Gy. SBRT was delivered using the volumetric modulated arc therapy (VMAT) by RapidArc. Primary end-point of this study was freedom from local progression (FFLP), secondary end-points were overall survival (OS), progression free survival (PFS) and toxicity. Median Clinical Target Volume (CTV) was 25.6 cm3 (3.2-78.8 cm3) and median Planning Target Volume (PTV) was 70.9 cm3 (20.4- 205.2 cm3). The prescription dose was delivered in 25 patients (83%), in 5 patients (17%) it was reduced to 36Gy in 6 fractions not to exceed the dose constraints of organs at risk (OARs). Median follow-up was 11 months (2–28 months). FFLP was 91% at 6 months, 85% at median follow-up and 77% at 1 and 2 years. For the group with prescription dose of 45Gy, FFLP was 96% at 1 and 2 years. The median PFS was 8 months. The OS was 47% at 1 year and median OS was 11 months. At the end of the follow-up, 9 patients (32%) were alive and 4 (14%) were free from progression. No patients experienced G ≥ 3 acute toxicity. Our preliminary results show that SBRT can obtain a satisfactory local control rate for unresectable locally advanced and recurrent pancreatic adenocarcinoma. This fractionation schedule is feasible, and no G ≥ 3 toxicity was observed. SBRT is an effective emerging technique in the multi-modality treatment of locally advanced pancreatic tumors

    Pancreatic head cancer is a common but the most lethal cancer of the human digestive system. It is invasive, resulting in early infiltration of adjacent structures and lymph node and distant metastases. Its biological characteristics of neurotropic growth lead to early neural invasion (NI) which is an independent prognostic factor of survival for pancreatic cancer. Radical surgical resection remains the only form of curative treatment. The extent of surgical resection and whether extended resection results in better long-term survival have been controversial. Studies have reported that peripancreatic plexus invasion is a frequent cause of pancreatic cancer recurrence and death. The relationship between cancer microenvironment and nerve cells, and whether the peripancreatic nerve plexus nearby needs to be resected require further studies. The present review aims to discuss the role of peripancreatic nerve and its implications in pancreatic head cancer resection. PMID:26458369

  7. Thymostimulin in advanced hepatocellular carcinoma: A phase II trial

    International Nuclear Information System (INIS)

    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. 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. 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 < 0.001) or a low AFP-level (p < 0.001) were associated with better survival, but not therapy modalities other than thymostimulin (p = 0.1) or signs of an invasive HCC phenotype such as vascular invasion (p = 0.3) and metastases (p = 0.1). The only variables independently related to survival in the Cox's regression model were Okuda stage and presence of liver cirrhosis (p < 0.01) as well as response to thymostimulin (p < 0.05). Of 39/44 patients evaluable for response, two obtained complete responses (one after concomitant radiofrequency ablation), five partial responses (objective response 18%), twenty-four stable disease (tumor control rate 79%) and eight progressed. Median progression-free survival was 6.4 months (95% CI 0.8–12). Grade 1 local reactions following injection were the only side effects. 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

  9. Estimating Optimal Dose of Twice-Weekly Gemcitabine for Concurrent Chemoradiotherapy in Unresectable Pancreatic Carcinoma: Mature Results of GEMRT-01 Phase I Trial

    International Nuclear Information System (INIS)

    Purpose: To accurately determine the maximal tolerated dose, feasibility, and antitumor activity of concurrent chemoradiotherapy including twice-weekly gemcitabine in patients with unresectable pancreatic adenocarcinoma. Methods and Materials: Eligible patients with histologically proven adenocarcinoma of the pancreas were included in this Phase I trial. Radiotherapy was delivered to a total dose of 50 Gy. Concurrent chemotherapy with twice-weekly gemcitabine was administered during the 5 weeks of radiotherapy, from an initial dose of 30 mg/m2. The gemcitabine doses were escalated in 10-mg/m2 increments in a three-plus-three design, until dose-limiting toxicities were observed. Results: A total of 35 patients were included in the trial. The feasibility of chemoradiotherapy was high, because all the patients received the planned total radiation dose, and 26 patients (74%) received ≥70% of the planned chemotherapy dose. The mean total delivered dose of gemcitabine was 417 mg/m2 (i.e., 77% of the prescribed dose). The maximal tolerated dose of twice-weekly gemcitabine was 70 mg/m2. Of the 35 patients, 13 had a partial response (37%) and 21 had stable disease (60%). Overall, the median survival and the 6-, 12-, and 18-month survival rates were 10.6 months and 82%, 31%, and 11%, respectively. Survival was significantly longer in patients with an initial performance status of 0 or 1 (p = .004). Conclusion: Our mature data have indicated that gemcitabine doses can be increased ≤70 mg/m2, when delivered twice-weekly with concurrent radiotherapy. This combination shows promises to achieve better recurrence-free and overall survival. These results will serve as a basis for further implementation of the multimodal treatment of locally advanced pancreatic carcinoma.

  10. Systemic Chemotherapy for Advanced Hepatocellular Carcinoma: Past, Present, and Future

    Full Text Available Systemic chemotherapy is one of the most important treatment modalities for advanced hepatocellular carcinoma (HCC. Before the introduction of sorafenib, cytotoxic agents, hormonal therapies, or many combinations of these were the mainly used modalities for systemic chemotherapy of advanced HCC. However, such regimens were of only limited value in clinical practice, because some randomized controlled studies comparing promising regimens with no treatment or doxorubicin alone failed to show any overall survival advantage. In two pivotal phase III placebo-controlled studies, the SHARP trial and the Asia-Pacific trial, sorafenib was demonstrated to significantly delay the time to progression and the overall survival time in patients with advanced HCC. Therefore, sorafenib therapy has come to be acknowledged as a standard therapy for advanced HCC worldwide. After the introduction of sorafenib, a number of phase III trials of various molecular-targeted agents vs. sorafenib as first-line chemotherapy and of various molecular-targeted agents vs. placebo as second-line chemotherapy have been conducted to determine if any of these agents could offer a survival benefit, however, none of the agents examined so far has been demonstrated to provide any survival benefit over sorafenib or placebo. Recently, favorable treatment efficacies have been reported in some clinical trials of molecular-targeted agents in the biomarker-enriched population. Development of individualized cancer treatments using molecular-targeted agents based on the results of genome-sequencing is aggressively ongoing. Furthermore, immune-oncologic agents, such as anti-CTLA-4 antibody and anti-PD-1/PD-L1 antibody, have been reported to provide promising outcomes. Thus, various novel systemic chemotherapeutic agents are currently under development, and further improvements in the treatment outcomes are expected.

    Background: Cancer patients commonly suffer from weight loss since rapid tumor growth can cause catabolic metabolism and depletion of energy stores such as abdominal fat. In locally advanced pancreatic cancer this is even more pronounced due to abdominal pain, fatigue, nausea or malnutrition. In the present article, we quantify this frequently observed weight loss and assess its impact on outcome and survival. Methods: Data on demographics, biometrics, toxicity and survival were collected for the last 100 patients treated with neoadjuvant chemoradiation for locally advanced pancreatic cancer at our department (45.0 Gy and boost up to 54.0 Gy plus concurrent and subsequent gemcitabine), and the subcutaneous fat area at the umbilicus level was measured by computer tomography before and after chemoradiation. Results: After chemoradiation, patients showed a highly statistically significant weight loss and reduction of the subcutaneous fat area. We could determine a very strong correlation of subcutaneous fat area to patient BMI. By categorizing patients according to their BMI based on the WHO classification as slender, normal, overweight and obese, we found improved but not statistically significant survival among obese patients. Accordingly, patients who showed less weight loss tended to survive longer. Conclusions: In this study, patients with pancreatic cancer lost weight during chemoradiation and their subcutaneous fat diminished. Changes in subcutaneous fat area were highly correlated with patients' BMI. Moreover, obese patients and patients who lost less weight had an improved outcome after treatment. Although the extent of weight loss was not significantly correlated with survival, the observed trend warrants greater attention to nutritional status in the future. (orig.)

    Objective To explore the efficacy and safty of sorafenib in Child-Pugh class B to class C hepatocellular carcinoma (HCC). Methods In this three-center open-label study from November 2011 to May 2013, we randomly assigned 189 patients with advanced Child-Pugh class B or C HCC patients into two groups, one group with 95 patient to receive sorafenib (400 mg a time, twice a day) and the other group with 94 patients to receive best supportive care. The primary end points were progression-free survival and overall survival. Results The median progression-free survival was 2.2 months and 1.9 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.55; 95% confidence interval, 0.40-0.75;P=0.002). The median overall survival was 4.0 months and 3.5 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.48;95%confidence interval, 0.35-0.68;P Conclusions Sorafenib is safe in patients with liver function impaired advanced HCC. It is effective in terms of progression-free survival and overall survival compared with best supportive care. Liver functions are the important predictive factors.

    2016-04-01

    In the last couple of years incretin-based antidiabetic drugs became increasingly popular and widely used for treating patients with type 2 diabetes. Immediately after launching, case reports and small case series were published on the potential side effects of the new drugs, with special attention to pancreatic disorders such as acute pancreatitis or pancreatic cancer. As clinical observations accumulated, these side-effects were noted with nearly all drugs of this class. Although these side-effects proved to be rare, an intensive debate evolved in the literature. Opinion of diabetes specialists and representatives of pharmaceutical industry as well as position statements of different international scientific boards and health authorities were published. In addition, results of randomized clinical trials with incretin-based therapy and meta-analyses became available. Importantly, in everyday clinical practice, the label of the given drug should be followed. With regards to incretins, physicians should be cautious if pancreatitis in the patients' past medical history is documented. Early differential diagnosis of any abdominal pain during treatment of incretin-based therapy should be made and the drug should be discontinued if pancreatitis is verified. Continuous post-marketing surveillance and side-effect analysis are still justified with incretin-based antidiabetic treatment in patients with type 2 diabetes. PMID:27017851

  15. Radioimmunotherapy for pancreatic carcinoma using 131I-labeled monoclonal antibody Nd2 in xenografted nude mice

    International Nuclear Information System (INIS)

    We investigated the biodistribution, radiolocalization, and radioimmunotherapeutic potential of 131I-labeled Nd2 in athymic nude mice bearing human pancreatic carcinoma xenografts. 131I-Nd2 was accumulated at high levels in the tumor, in contrast to blood, liver, spleen, and other normal organs. The tumor was clearly delineated in scintigraphs. The volumes of tumors of mice injected with 7.4 MBq of 131I-Nd2 were 80% less than those of tumors before injection of radiolabeled Nd2. Fibrous or vacuolar degeneration was seen in histological sections of tumors of 7-week-treated mice. The growth of tumors in mice treated with misonidazole, a hypoxic cell radiosensitizer, and then injected twice with 3.7 MBq of 131I-Nd2 was suppressed over 7 weeks. Neither leucocytopenia nor thrombocytopenia was severe after injection of radiolabeled Nd2. Thus 131I-labeled Nd2 may have clinical application in the radioimmunotherapy of pancreatic cancer.

    Adoptive immunotherapy using cytokine-induced killer (CIK) cells is a promising cancer treatment, but its efficacy is restricted by various factors, including the accumulation of myeloid-derived suppressor cells (MDSCs). In this study, we determine whether chemotherapeutic drugs that reduce MDSC levels enhance the efficacy of CIK cell therapy in the treatment of solid tumors. Fifty-three patients were included in this study; 17 were diagnosed with metastatic renal cell carcinoma (MRCC), 10 with advanced pancreatic cancer (PC), and 26 with metastatic melanoma (MM). These patients were divided into two groups: CIK cell therapy alone and CIK cell therapy combined with chemotherapy. Combining CIK cell therapy and chemotherapy increased 1-year survival rates and median survival times in MRCC and PC patients, but not in MM patients. The disease control rate did not differ between treatment groups for MRCC or MM patients, but was higher in PC patients receiving combined treatment than CIK cell treatment alone. These data suggest that addition of MDSC-decreasing chemotherapy to CIK cell therapy improves survival in MRCC and PC patients. PMID:26716894

  17. Therapy of metastatic pancreatic neuroendocrine tumors (pNETs). Recent insights and advances

    International Nuclear Information System (INIS)

    Neuroendocrine tumors (NETs) [carcinoids, pancreatic neuroendocrine tumors (pNETs)] are becoming an increasing clinical problem because not only are they increasing in frequency, but they can frequently present with advanced disease that requires diagnostic and treatment approaches different from those used in the neoplasms that most physicians are used to seeing and treating. In the past few years there have been numerous advances in all aspects of NETs including: an understanding of their unique pathogenesis; specific classification systems developed which have prognostic value; novel methods of tumor localization developed; and novel treatment approaches described. In patients with advanced metastatic disease these include the use of newer chemotherapeutic approaches, an increased understanding of the role of surgery and cytoreductive methods, the development of methods for targeted delivery of cytotoxic agents, and the development of targeted medical therapies (everolimus, sunitinib) based on an increased understanding of the disease biology. Although pNETs and gastrointestinal NETs share many features, recent studies show they differ in pathogenesis and in many aspects of diagnosis and treatment, including their responsiveness to different therapies. Because of limited space, this review will be limited to the advances made in the management and treatment of patients with advanced metastatic pNETs over the past 5 years. (author)

    2003-01-01

    Full Text Available Abstract The incidence and mortality of pancreatic adenocarcinoma are nearly coincident having a five-year survival of less than 5%. Enormous advances have been made in our knowledge of the molecular alterations commonly present in ductal cancer and other pancreatic malignancies. One significant outcome of these studies is the recognition that common ductal cancers have a distinct molecular fingerprint compared to other nonductal or endocrine tumors. Ductal carcinomas typically show alteration of K-ras, p53, p16INK4, DPC4 and FHIT, while other pancreatic tumor types show different aberrations. Among those tumors arising from the exocrine pancreas, only ampullary cancers have a molecular fingerprint that may involve some of the same genes most frequently altered in common ductal cancers. Significant molecular heterogeneity also exists among pancreatic endocrine tumors. Nonfunctioning pancreatic endocrine tumors have frequent mutations in MEN-1 and may be further subdivided into two clinically relevant subgroups based on the amount of chromosomal alterations. The present review will provide a brief overview of the genetic alterations that have been identified in the various subgroups of pancreatic tumors. These results have important implications for the development of genetic screening tests, early diagnosis, and prognostic genetic markers.

    Objective: To evaluate the efficacy and toxicity of M-VCA (methortrexate 30 mg/m2, vincristine 2 mg, cisplatin 70 mg/m2, adriamycin 30 mg/m2) combination chemotherapy for advanced nasopharyngeal carcinoma. Methods: Thirty-five patients with advanced nasopharyngeal carcinoma, including 11 patients with untreated local advanced nasopharyngeal carcinoma and 24 patients with local-regional recurrent or metastatic nasopharyngeal carcinoma, received the chemotherapy of M-VCA. The cycle was repeated on day 22 for two cycles. All patients completed the chemotherapy courses. Results: The overall response rate was 75%, with untreated local advanced nasopharyngeal carcinomas 11/11(100%), local-regional recurrent nasopharyngeal carcinomas 12/18(67%), lung metastases 8/9(89%), bone metastases 5/9(56%), and liver metastases 1/2(50%). The main side effects included mild to moderate degree alopecia, nausea/vomiting, and neutropenia. Conclusion: M-VCA is well tolerated and has good efficacy for advanced nasopharyngeal carcinoma and is worth investigating further.

However, because several randomized Phase III studies testing new multikinase inhibitors failed, sorafenib remains the standard of first-line systemic therapy for patients with advanced HCC. Field practice studies worldwide have suggested that in daily practice, physicians are adopting either a preemptive dose modification or a ramp-up strategy to improve the compliance of their patients. In addition, accumulating data have suggested that patients with Child–Pugh class B liver function can tolerate sorafenib as well as patients with Child–Pugh class A liver function, although the actual benefit of sorafenib in patients with Child–Pugh class B liver function has yet to be confirmed. Whether sorafenib can be used as an adjunctive therapy to improve the outcomes of intermediate-stage HCC patients treated with transcatheter arterial chemoembolization or early-stage HCC patients after curative therapies is being investigated in several ongoing randomized Phase III studies. An increasing number of studies have reported that sorafenib exerts "off-target" effects, including the modulation of signaling pathways other than Raf/MEK/ERK pathway, nonapoptotic cell death mechanisms, and even immune modulation. Finally, although sorafenib in combination with chemotherapy or other targeted therapies has the potential to improve therapeutic efficacy in

  6. The role of brachytherapy in the management of unresectable pancreatic carcinoma

    International Nuclear Information System (INIS)

    Introduction: this is a retrospective study to evaluate the efficacy of intra-operative brachytherapy (BT) in the management of unresectable adenocarcinoma of the pancreas. Material and methods: between 1989 and 1994, 33 patients with biopsy proven unresectable adenocarcinoma of the pancreas were treated with Iodine- 125 implant. The presenting symptoms were pain (24 patients). Sixteen patients had stage II (T3N0M0), 8 were stage III (T2-3, N1, M0), 6 were stage IV (T3, N0-1, M1), and three patients were treated for recurrence after external beam radiation therapy (ERT) and chemotherapy (CT). Two patients underwent partial tumor resection at laparotomy and 28 patients had a bypass procedure to alleviate biliary or gastrointestinal obstruction. Eight patients received postoperative ERT and 31 received 5 FU CT. The median target volume, median implanted sources, and median target dose were 23 cc, 43, 22.7 mci, and 15,900 cGy, respectively. Results and discussion: the median survival for the entire group was 10.5 months and the 2 year actuarial survival (2- YS) was 17%. The median and 2-YS rates were superior for lesions located in the head compared to those in body or tail (13.5 months and 24% vs 5 months and 0%, respectively). Complete pain relief was achieved in 76% of the patients. There were no postoperative deaths. Postoperative complications were observed in 6% (2 patients): one patient developed pancreatico-biliary fistula, successfully treated by endoscopic placement of bilary stent, and the other had sepsis controlled with antibiotics. Conclusion: our experience suggests that the combined approach of BT and CT is beneficial in patients with locoregionally advanced unresectable carcinoma of the pancreas. It provides excellent palliation and improves survival with acceptable toxicity

    We undertook a phase I dose-escalation study of verteporfin photodynamic therapy (PDT) in 15 patients with locally advanced pancreatic cancer. Needle placement and laser delivery were technically successful in all patients. Thirteen patients were treated with a single laser fibre. Three treatments were carried out each at 5, 10 and 20 J/cm2; and 5 treatments (4 patients) at 40 J/cm2. A further 2 patients were treated with 2 or 3 laser fibres at 40 J/cm2. Tumour necrosis was measured on CT (computed tomography) by two radiologists 5 days after treatment. There was a clear dosedependent increase in necrosis with a median area of 20 x 16 mm (range 18 x 16 to 35 x 30 mm) at 40 J/cm2. In the 2 patients treated with multiple fibres, necrosis was 40 x 36 mm and 30 x 28 mm, respectively. There were no early complications in patients treated with a single fibre. Both patients treated with multiple fibres had evidence on CT of inflammatory change occurring anterior to the pancreas but without clinical deterioration. These results suggest that single fibre verteporfin PDT is safe in a clinical setting up to 40J/cm2 and produces a dose-dependent area of pancreatic necrosis.

    The aim was to evaluate the diagnostic value of {sup 18}F-fluorodeoxyglucose-positron emission tomography ({sup 18}F-FDG PET), combined {sup 18}F-fluorodeoxyglucose-positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) and endoscopic ultrasonography (EUS) in diagnosing patients with pancreatic carcinoma. MEDLINE, EMBASE, Cochrane library and some other databases, from January 1966 to April 2009, were searched for initial studies. All the studies published in English or Chinese relating to the diagnostic value of {sup 18}F-FDG PET, PET/CT and EUS for patients with pancreatic cancer were collected. Methodological quality was assessed. The statistic software called 'Meta-Disc 1.4' was used for data analysis. Results: 51 studies were included in this meta-analysis. The pooled sensitivity estimate for combined PET/CT (90.1%) was significantly higher than PET (88.4%) and EUS (81.2%). The pooled specificity estimate for EUS (93.2%) was significantly higher than PET (83.1%) and PET/CT (80.1%). The pooled DOR estimate for EUS (49.774) was significantly higher than PET (32.778) and PET/CT (27.105). SROC curves for PET/CT and EUS showed a little better diagnostic accuracy than PET alone. For PET alone, when interpreted the results with knowledge of other imaging tests, its sensitivity (89.4%) and specificity (80.1%) were closer to PET/CT. For EUS, its diagnostic value decreased in differentiating pancreatic cancer for patients with chronic pancreatitis. In conclusion, PET/CT was a high sensitive and EUS was a high specific modality in diagnosing patients with pancreatic cancer. PET/CT and EUS could play different roles during different conditions in diagnosing pancreatic carcinoma.

  12. Requirement of Nuclear Factor κB for Smac Mimetic–Mediated Sensitization of Pancreatic Carcinoma Cells for Gemcitabine-Induced Apoptosis

    2011-12-01

    Full Text Available Defects in apoptosis contribute to treatment resistance and poor outcome of pancreatic cancer, calling for novel therapeutic strategies. Here, we provide the first evidence that nuclear factor (NF κB is required for Smac mimetic– mediated sensitization of pancreatic carcinoma cells for gemcitabine-induced apoptosis. The Smac mimetic BV6 cooperates with gemcitabine to reduce cell viability and to induce apoptosis. In addition, BV6 significantly enhances the cytotoxicity of several anticancer drugs against pancreatic carcinoma cells, including doxorubicin, cisplatin, and 5-fluorouracil. Molecular studies reveal that BV6 stimulates NF-κB activation, which is further increased in the presence of gemcitabine. Importantly, inhibition of NF-κB by overexpression of the dominant-negative IκBα superrepressor significantly decreases BV6- and gemcitabine-induced apoptosis, demonstrating that NF-κB exerts a proapoptotic function in this model of apoptosis. In support of this notion, inhibition of tumor necrosis factor α (TNFα by the TNFα blocking antibody Enbrel reduces BV6- and gemcitabine-induced activation of caspase 8 and 3, loss of mitochondrial membrane potential, and apoptosis. By demonstrating that BV6 and gemcitabine trigger a NF-κB–dependent, TNFα-mediated loop to activate apoptosis signaling pathways and caspase-dependent apoptotic cell death, our findings have important implications for the development of Smac mimetic–based combination protocols in the treatment of pancreatic cancer.

    During the development and progression of severe acute pancreatitis (SAP), conspicuous immune dysregulation develops, which is mainly manifested as excessive immune response in the early stage and immunosuppression in the late stage.This process involves complex changes in a variety of immune molecules and cells, such as cytokines, complements, lymphocytes,and leukocytes. With the gradual deepening of studies on the development and progression of SAP, the role of immune dysregulation in the pathogenesis of SAP has attracted more and more attention. In this article, we review the advances in research on the immune dysregulation in SAP and the immunotherapy of this disease through exploring the formation of excessive immune response and immune suppression as well as their mutual transformation.

    2007-01-01

    Despite progress in the treatment of advanced and metastatic pancreatic cancer (PC), the outcome of this disease remains dismal for the majority of patients.Given the moderate efficacy of treatment, prognostic factors may help to guide treatment decisions. Several trials identified baseline performance status as an important prognostic factor for survival. Unfit patients with a Karnofsky performance status (KPS) below 70% only have a marginal benefit from chemotherapy with gemcitabine (Gem) and may often benefit more from optimal supportive care. Once, however, the decision is taken to apply chemotherapy, KPS may be used to select either mono- or combination chemotherapy. Patients with a good performance status (KPS = 90%-100%) may have a significant and clinically relevant survival benefit from combination chemotherapy. By contrast, patients with a poor performance status (KPS ≤ 80%) have no advantage from intensified therapy and should rather receive single-agent treatment.

    Background Pancreatic cancer is a highly malignant tumor affecting an ever increasing number of patients with a mean 5-year survival rate below 4%. Therefore, gene therapy for cancer has become a potential novel therapeutic modality. In this study we sought to determine the inhibitory effects of adenovirus-mediated human interleukin-24 (AdhlL-24) on pancreatic cancer.Methods Human interleukin-24 gene was cloned into replication-defective adenovirus specific for patu8988 tumor cells by virus recombination technology. Reverse transcription-polymerase chain reaction and Western blotting analysis were used to determine the expression of human interleukin-24 mRNA in patu8988 cells in vitro. Induction of apoptosis by overexpression of human interleukin-24 in patu8988 cells was determined by flow cytometry. In vivo efficacy of adenoviral delivery of human interleukin-24 was assessed in nude mice (n=10 for each group) bearing patu8988 pancreatic cancer cell lines by determining inhibition of tumor growth, endothelial growth factor and CD34 expression, and intratumoral microvessel density (MVD).Results The recombinant adenovirus vector AdVGFP/IL-24 was constructed with a packaged recombinant retrovirus titer of 1.0x1010 pfu/ml and successfully expressed of both mRNA and protein in patu8988 cells. The AdVGFP/IL-24 induced apoptosis of patu8988 tumor cells in vitro and significantly inhibited tumor growth in vivo (P <0.05). The intratumoral MVD decreased significantly in the treated tumors (P <0.05).Conclusion The recombinant adenovirus AdGFP/IL-24 can effectively express biologically active human interleukin-24, which results in inhibition of pancreatic cancer growth.

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001). Although the number of liver metastases is higher in the right lobe than in the left lobe in both groups, there is a significant difference in the ratio of metastases between the right and the left hemi-liver.

    International Nuclear Information System (INIS)

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001). Although the number of liver metastases is higher in the right lobe than in the left lobe in both groups, there is a significant difference in the ratio of metastases between the right and the left hemi-liver. This supports the existence of a streamline phenomenon and a selective lobar distribution of metastases within the liver. (orig.)

    Advanced hepatocellular carcinoma (HCC) remains a fatal disease even in the era of targeted therapies. Intra-arterial chemotherapy (IACT) can provide therapeutic benefits for patients with locally advanced HCC who are not eligible for local therapies or are refractory to targeted therapies. The aim of this retrospective study was to analyze the effect of IACT with cisplatin and doxorubicin on advanced HCC. Methods. Patients with advanced HCC who were not eligible for local therapies or were r...

  5. Whole abdominal irradiation following chemotherapy in advanced ovarian carcinoma

    International Nuclear Information System (INIS)

    One hundred and sixteen patients with advanced ovarian carcinoma, who underwent primary cytoreductive surgery, received 6-11 courses of chemotherapy by cis-platin (50 mg/m2) and adriamycin (50 mg/m2) every 21 days. This was followed by second look laparotomy in 66 patients with no clinical evidence of disease. Consolidation abdominal irradiation was administered to 43 patients. Two techniques of irradiation were employed: between 1980-1983 whole abdominal irradiation was used and patients were to receive 3000 cGy in 4 weeks (Schedule I). Due to myelosuppression only 13 of 26 patients (50%) completed the planned dose of radiation. Between 1983-1985 the target volume was divided into upper and lower parts. First, the lower abdomen received 3000 cGy in 3 weeks, and then the upper abdomen received the same dose (Schedule II). Sixteen of seventeen patients (94%) thus treated, completed the planned dose of radiation. The actuarial survival for all 116 patients was 28% of 5 years. Irradiated patients with negative second look laparotomy had a survival probability of 100% at 24 months. Irradiated patients with microscopic disease at second look operation had an actuarial 5-year survival of 66%. Patients with minimal residual disease at second look laparotomy, receiving consolidation abdominal irradiation, had an actuarial survival of 5% only at 36 months. It is concluded that consolidation radiotherapy is effective in patients with negative or microscopic residual disease at second-look laparotomy. In regard to bone marrow tolerance, split field technique of irradiation is preferred

  6. Locally advanced cervix carcinoma - innovation in combined modality therapy

    International Nuclear Information System (INIS)

    Locally advanced cervical carcinoma continues to be a challenge to the clinician due to local failure as well as systemic metastases. Standard intracavitary and external beam techniques result in local control rates of only 35-65%, with long term survival rates of 25-60% in patients with state IIIA-IVA disease, indicating the need to identify new treatment strategies. Optimization programs for remote-afterloading interstitial brachytherapy allow the delivery of higher local doses of radiation to volumes that more closely approximate tumor target volumes as identified on MR scans, leading to improved therapeutic ratios. Identification of subsets of patients more likely to fail standard therapy, either locally or systemically, may be possible through such techniques as in vivo measurements of hypoxia with Eppendorf oxygen electrodes, interstitial fluid pressure measurements, the Comet assay, and nitroimidazole binding methods. Traditional chemotherapies, administered in either a neoadjuvant role or concomitantly with radiation have been disappointing in prospective trials. A variety of new agents are being investigated to determine if they can increase the frequency or duration of complete response. The taxanes, with response rates of 17-23% by themselves, are being assessed as potential radiosensitizers. The camptotheicin CRT-11 (Irinotecan) has demonstrated activity in platinum resistant cervix cancer, with response rates of 24%. Bioradiotherapeutic approaches, using 13-cis-retinoic acid and interferon-2a, are undergoing phase II studies. Neoangiogenesis inhibitors and vaccines against HPV are also being examined. The aggressive pursuit of techniques that help identify those patients most likely to fail, that allow the delivery of higher radiation doses more safely to the target volume, and that incorporate the use of more effective systemic therapies is necessary to improve the outcome for this disease

  7. Effect of antidepressants on body weight, ethology and tumor growth of human pancreatic carcinoma xenografts in nude mice

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    AIM: To investigate the effects of mirtazapine and fluoxetine, representatives of the noradrenergic and specific serotonergic antidepressant (NaSSA) and se- lective serotonin reuptake inhibitor (SSRI) antidepres- sant respectively, on body weight, ingestive behavior, locomotor activity and tumor growth of human pancre- atic carcinoma xenografts in nude mice. METHODS: A subcutaneous xenograft model of hu- man pancreatic cancer cell line SW1990 was estab- lished in nude mice. The tumor-bearing mice were ran- domly divided into mirtazapine group [10 mg/(kg'd)], (an equivalent normal saline solution) (7 mice in each group). Doses of all drugs were administered orally, once a day for 42 d. Tumor volume and body weight were measured biweekly. Food intake was recorded once a week. Locomotor activity was detected weekly using an open field test (OFT). RESULTS: Compared to the fluoxetine, mirtazapine significantly increased food intake from d 14 to 42 and attenuated the rate of weight loss from d 28 to 42 (t = 4.38, P = 10.89, P < 0.01). These effects disappeared in the mirtazapine and fluoxetine groups during 2-6 wk. The grooming activity was higher in the mirtazapine group than in the fluoxetine group (10.1 ± 2.1 vs 7.1 ± 1.9 ) (t = 2.40, P < 0.05) in the second week. There was no significant difference in tumor vol- ume and tumor weight of the three groups. CONCLUSION: Mirtazapine and fluoxetine have no effect on the growth of pancreatic tumor. However, mirtazapine can significantly increase food intake and improve nutrition compared with fluoxetine in a pan- creatic cancer mouse model.

  8. Chemoradiotherapy as preoperative treatment in locally advanced unresectable pancreatic cancer patients: results of a feasibility study

    International Nuclear Information System (INIS)

    Purpose: The combination of radiotherapy and fluorouracil (5-FU) in patients with locally unresectable pancreatic carcinoma has led to a significant increase in survival in comparison with radiotherapy alone. Doxifluridine (5-DFUR) is an orally active fluoropyrimidine, and its cytotoxic metabolite (5-FU) may concentrate in areas of high tumor vascularisation. This trial was carried out with the aims of improving locoregional control and making lesions resectable in patients with unresectable pancreatic cancer. Methods: 5-DFUR was given at a dose of 500 mg/m2 b.i.d. by way of mouth for 4 days every other week for a total of four courses, with leucovorin 25 mg b.i.d. orally being given 2 hours before each 5-DFUR administration. External beam RT was administered at a dose of 1000 cGy per week for 3 weeks, followed by a 2-week break and then by 1000 cGy per week for a further 2 weeks (a total dose of 5000 cGy). The patients were restaged 4 weeks after the end of treatment and explored for resection in cases of partial response (PR). Results: A total of 32 patients were treated between 1992 and 1997. Ab initio un resectability was shown by laparotomy (16 cases) or computed tomography (16 cases), and was due to vascular invasion in 27 patients, massive regional nodal metastases in nine, and both in four. The median age was 63 years (range 36-71); performance status (PS) (ECOG): 0-1 28 and PS 2 = 4. All the patients had measurable disease and were evaluable for response. There were seven PR (22%), 10 SD (31%), and 15 PD (47%). All of the responders underwent surgical exploration, and radical resection was possible in 5. Three of these patients are still disease-free with a follow-up of 18, 27, and 65 months; the other two cases relapsed 11 and 14 months after surgery. The median survival time was 9 months for the entire group, and 1-year survival rate was 31%. The treatment was never stopped because of toxicity. There were no CTC-NCI grade 3 or 4 toxic events; grade 1

    Solitary pancreatic involvement of tuberculosis is rare,especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms.Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques.However, they are composed of a variety of neoplasms with a wide range of malignant potential,and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms. Non-surgical diagnosis of pancreatic tuberculosis is inconclusive and continues to be a challenge in many cases. If so,then laparotomy should be employed to establish the diagnosis. Therefore, pancreatic tuberculosis should be kept in mind during the differential diagnosis of solitary cystic masses in the pancreas. We report a patient who had solitary pancreatic tuberculosis masquerading as pancreatic serous cystadenoma.

    BACKGROUND:The role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of acute pancreatitis has evolved over years since its introduction in 1968. Its importance in diagnosing the etiology of pancreatitis has steadily declined with the advent of less invasive diagnostic tools. The therapeutic implications of ERCP in acute pancreatitis are many fold and are directed towards management of known etiological factors or its related complications. This article highlights the current status of ERCP in acute pancreatitis. DATA SOURCES:An English literature search using PubMed database was conducted on ERCP in acute pancreatitis, the etiologies and complications of pancreatitis amenable to endotherapy and other related subjects, which were reviewed. RESULTS: ERCP serves as a primary therapeutic modality for management of biliary pancreatitis in speciifc situations, pancreatitis due to microlithiasis, speciifc types of sphincter of Oddi dysfunction, pancreas divisum, ascariasis and malignancy. In recurrent acute pancreatitis and smoldering pancreatitis it has a deifnite therapeutic utility. Complications of acute pancreatitis including pancreatic-duct disruptions or leaks, benign pancreatic-lfuid collections and pancreatic necrosis can be beneifcially dealt with. Intraductal ultrasound and pancreatoscopy during ERCP are useful in detecting pancreatic malignancy. CONCLUSIONS:The role of ERCP in acute pancreatitis is predominantly therapeutic and occasionally diagnostic. Its role in the management continues to evolve and advanced invasive procedures should be undertaken only in centers dedicated to pancreatic care.

Patients were treated with gemcitabine (GEM alone, S-1 (tegafur, gimeracil, and oteracil potassium alone, or GEM plus S-1. Patients were divided into the clinical trial eligible group (arm eligible or the ineligible group (arm ineligible. We evaluated the efficacy and the safety of the chemotherapy.Results: A total of 23 patients out of 75 (31% belonged to the ineligible group, for the following reasons: 20 patients had poor performance status, eight had massive ascites, one had synchronous malignancy, and one had icterus. The median progression-free survival (PFS was 3.5 months, and the median overall survival (OS was 6.7 months in all patients. In arm eligible, median PFS was 4.5 months, and median OS was 10.5 months. In arm ineligible, median PFS was 1.1 months, and median OS was 2.9 months.Conclusion: The outcome of the patients who did not meet the eligibility criteria was very poor. It is important to select the patients that could benefit from either chemotherapy or optimal supportive care.Keywords: gemcitabine, S-1, clinical practice

  12. Intensity modulated radiotherapy for locally advanced and metastatic pancreatic cancer: a mono-institutional retrospective analysis

    International Nuclear Information System (INIS)

    To evaluate the role of intensity modulated radiotherapy (IMRT) for locally advanced pancreatic cancer (LAPC) and metastatic pancreatic cancer (MPC), and the prognostic factors in the setting of multidisciplinary approach strategies. 63 patients with LAPC and MPC receiving IMRT in our institution were retrospectively identified. Information on patient baseline, treatment characteristics and overall survival (OS) time were collected. Data of pain relief and toxicity were evaluated. Univariate and multivariate analyses were conducted to investigate the prognostic factors. All patients received IMRT with a median dose of 46.0 Gy. The median OS for LAPC and MPC patients were 15.7 months and 8.0 months, respectively (p = 0.029). Symptomatic improvements were observed in the 44 patients with abdominal/back pain after radiotherapy (RT) or concurrent chemoradiotherapy (CCRT), particularly in those with severe pain. Only 13.9% and 14.8% cases presented Grade ≥ 3 hematologic toxicities in RT and CCRT group, while no cases developed Grade ≥ 3 non-hematologic toxicities in both groups. Multivariate analysis indicated that tumors located in pancreas body/tail (HR 0.28, p = 0.008), pretreatment CA19-9 < 1000 U/mL (HR 0.36, p = 0.029) and concurrent chemotherapy (HR 0.37, p = 0.016) were independent favorable predictors for OS. CCRT further improved OS for LAPC and MPC with acceptable toxicities, and use of RT markedly alleviated pain. Tumors located in pancreas body/tail, pretreatment CA19-9 level of < 1000 U/mL and CCRT were associated with better OS. However, regional intra-arterial chemotherapy did not show any survival benefit in our study

  13. Analysis of the clinical benefit of 5-fluorouracil and radiation treatment in locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose: To assess the palliative benefit of 5-fluorouracil (5-FU) and radiotherapy in patients with surgically unresectable localized pancreatic cancer. Methods and Materials: Twenty-five patients with locally advanced surgically unresectable symptomatic pancreatic cancer received 5-FU chemotherapy and local radiation therapy. They were retrospectively reviewed in regard to their clinical benefit response (a composite of measurement of pain assessment, weight, and Karnofsky performance status [KPS]), as well as radiological response, time to progression, and overall survival. Results: Median survival for the 25 patients was 9 months and median progression-free survival was 6 months. Thirty-two percent of patients survived in excess of 1 year. Analgesic requirements increased >50% in 2 patients and KPS deteriorated in 10 patients. Of the 13 remaining patients, 2 sustained a >7% weight loss and 2 gained weight post-treatment. Six patients improved in one parameter of analgesic consumption, weight loss or KPS without deteriorating in any others. Thus, the clinical benefit response index for 5-FU-radiation was 6/25 (24%). In terms of tumor response, 8 patients (44%) demonstrated a reduction in tumor volume post-treatment, 4 of whom (22%) experienced a >50% reduction. Four additional patients had radiologically stable disease. Conclusion: In this retrospective analysis, the clinical benefit response index for 5-FU-radiation was 24%, a value similar to the 23.8% reported for single agent gemcitabine. The median survival of 7 months was also similar to the 5.65 months reported for gemcitabine. The radiological partial response rate of 22% and the 1-year survival of 32% were higher for 5-FU-radiation than the reported values for gemcitabine. A randomized trial would be necessary to compare 5-FU-radiation to gemcitabine directly; however, from this review it did not appear that the overall palliative benefit of 5-FU-radiation was inferior to gemcitabine

  14. A retrospective study of neoadjuvant FOLFIRINOX in unresectable or borderline-resectable locally advanced pancreatic adenocarcinoma

    International Nuclear Information System (INIS)

    5-fluorouracil, leucovorin, irinotecan and oxaliplatin (FOLFIRINOX) is superior to gemcitabine in patients with metastatic pancreatic cancer who have a good performance status. We investigated this combination as neoadjuvant therapy for locally advanced pancreatic cancer (LAPC). In this retrospective series, we included patients with unresectable LAPC who received neoadjuvant FOLFIRINOX with growth factor support. The primary analysis endpoint was R0 resection rate. Eighteen treatment-naïve patients with unresectable or borderline resectable LAPC were treated with neoadjuvant FOLFIRINOX. The median age was 57.5 years and all had ECOG PS of 0 or 1. Eleven (61 %) had tumors in the head of the pancreas and 9 (50 %) had biliary stents placed prior to chemotherapy. A total of 146 cycles were administered with a median of 8 cycles (range 3-17) per patient. At maximum response or tolerability, 7 (39 %) were converted to resectability by radiological criteria; 5 had R0 resections, 1 had an R1 resection, and 1 had unresectable disease. Among the 11 patients who remained unresectable after FOLFIRINOX, 3 went on to have R0 resections after combined chemoradiotherapy, giving an overall R0 resection rate of 44 % (95 % CI 22–69 %). After a median follow-up of 13.4 months, the 1-year progression-free survival was 83 % (95 % CI 59-96 %) and the 1-year overall survival was 100 % (95 % CI 85-100 %). Grade 3/4 chemotherapy-related toxicities were neutropenia (22 %), neutropenic fever (17 %), thrombocytopenia (11 %), fatigue (11 %), and diarrhea (11 %). Common grade 1/2 toxicities were neutropenia (33 %), anemia (72 %), thrombocytopenia (44 %), fatigue (78 %), nausea (50 %), diarrhea (33 %) and neuropathy (33 %). FOLFIRINOX followed by chemoradiotherapy is feasible as neoadjuvant therapy in patients with unresectable LAPC. The R0 resection rate of 44 % in this population is promising. Further studies are warranted

    Disseminating tumors are one of the gravest medical problems. Here, we combine the tumor-specific apoptosis-inducing activity of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) with the ability of mesenchymal stem cells (MSCs) to infiltrate both tumor and lymphatic tissues to target primary tumors as well as disseminated cancer cells in a human pancreatic cancer mouse model. Furthermore, we targeted X-linked inhibitor of apoptosis protein (XIAP) by RNA interference (RNAi) inside the cancer cells to make use of the apoptosis sensitization as well the antimetastatic effect that is afforded by XIAP silencing. We generated MSCs, termed MSC.sTRAIL, that express and secrete a trimeric form of soluble TRAIL (sTRAIL). MSC.sTRAIL triggered limited apoptosis in human pancreatic carcinoma cells that were resistant to soluble recombinant TRAIL, which is most likely due to the enhanced effect of the direct, cell-mediated delivery of trimeric TRAIL. MSC.sTRAIL-mediated cell death was markedly increased by concomitant knockdown of XIAP by RNAi in the cancer cells. These findings were confirmed in xenograft models, in which tumors from the parental pancreatic carcinoma cells showed only growth retardation on treatment with MSC.sTRAIL, whereas tumors with silenced XIAP that were treated with MSC.sTRAIL went into remission. Moreover, animals with XIAP-negative xenografts treated with MSC.sTRAIL were almost free of lung metastasis, whereas animals treated with control MSCs showed substantial metastatic growth in the lungs. In summary, this is the first demonstration that a combined approach using systemic MSC-mediated delivery of sTRAIL together with XIAP inhibition suppresses metastatic growth of pancreatic carcinoma.

    Heinemann V

    2005-05-01

    Full Text Available Review of the role of chemoradiotherapy in the treatment of locally advanced pancreatic cancer with a specific focus on the technical feasibility and the integration of chemoradiotherapy into multimodal treatment concepts. Combined chemoradiotherapy of pancreatic cancer is a safe treatment with an acceptable profile of side effects when applied with modern planning and radiation techniques as well as considering tissue tolerance. Conventionally fractionated radiation regimens with total doses of 45-50 Gy and small-volume boost radiation with 5.4 Gy have found the greatest acceptance. Locoregional lymphatic drainage should be included in the planning of target volumes because the risk of tumor involvement and local or loco-regional recurrence is high. Up to now, 5-fluorouracil has been considered the "standard" agent for concurrent chemoradiotherapy. The role of gemcitabine given concurrently with radiation has not yet been defined, since high local efficacy may also be accompanied by enhanced toxicities. In addition, no dose or administration form has been determined to be "standard" up to now. The focus of presently ongoing research is to define an effective and feasible regimen of concurrent chemoradiotherapy. While preliminary results indicate promising results using gemcitabine-based chemoradiotherapy, reliable data derived from mature phase III trials are greatly needed. Intensity-modulated radiotherapy has been developed to improve target-specific radiation and to reduce organ toxicity. Its clinical relevance still needs to be defined.

  20. Systematic review of the value of chemoradiotherapy in the management of locally advanced pancreatic adenocarcinoma

    International Nuclear Information System (INIS)

    Introduction: At the request of the National Thesaurus of Gastrointestinal Cancer (T.N.C.D.), the S.O.R. program, led by the French National Cancer Institute (I.N.Ca), completed a systematic review to evaluate the value of chemoradiotherapy (C.R.T.) in the management of locally advanced pancreatic adenocarcinoma in collaboration with clinician experts. Methods: Results of a systematic literature search using Medline (from 1980 to 2008) were completed by a consult of evidence-based medicine web sites. All phase III randomized trials and systematic reviews concerning non-resectable locally advanced pancreatic adenocarcinoma and non-metastatic (stage III) were included in the study. Some phase II trials were also included if no phase III trials were retrieved. The following interventions were compared: C.R.T. versus best supportive care, C.R.T. versus radiotherapy, and C.R.T. versus chemotherapy. The modalities of C.R.T. regimens and the sequences of chemotherapy-C.R.T. versus C.R.T. were also studied. The quality and clinical relevance of the trials were evaluated using validated checklists, allowing associating each result with a level of evidence. Data synthesis was performed considering both efficacy and toxicity outcomes for each intervention. Results: Nineteen references were included in this systematic review: two meta-analyses, 11 randomized trials, five non-randomized trials and one randomized trial only published in abstract form. After a clinical and methodological critical appraisal, compared to the alternative best supportive care, concomitant C.R.T. increases overall survival (C). Concomitant C.R.T. compared to the radiotherapy alone increases the overall survival (B1) but is more toxic (B1). Concomitant C.R.T. compared to chemotherapy alone is not superior in terms of survival (B1) and increases toxicity (A). Concerning administration modalities of radiotherapy, recent data are in favour to a limited irradiation to the tumoral volume (C) and to a total

  1. Effect of 188Re-IGF-1 analogue in proliferation inhibition and apoptosis induction in pancreatic carcinoma cells

    International Nuclear Information System (INIS)

    Objective: To investigate the effect of 188Re-IGF-1 analogue (IGF-1A) in proliferation inhibition and apoptosis induction in human pancreatic carcinoma cell line Patu8988. Methods: IGF-1A was labeled with 188Re. Patu8988 cells were divided into an un-treated control group, IGF-1A group (1, 5, 10, 20 μg), 188ReO4-group (0.37, 1.85, 3.70, 7.40 MBq) and 188Re-IGF-1A group (0.37, 0.74, 1.85 MBq). The cell proliferation inhibition effects by the 188Re-IGF-1A and 188ReO4--were detected every day by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) test from 1 d to 7 d after administration, while the IGF-1 A group was tested every day from 1 d to 6 d after treatment. Inhibition rates were calculated. At 3 d after treatment with 188ReO4-and 188Re-IGF-1A (1.85, 3.70, 7.40 MBq), cell apoptosis was detected by flow cytometry. For biodistribution studies of 188Re-IGF-1A, 36 nude mice bearing Patu8988 cell xenografts were divided into 6 groups. At different time points (15 min, 1 h, 4 h, 1 d, 3 d and 5 d), 36 mice (n=6 per time point) were sacrificed and organs of interest were removed, weighted and measured for radioactivity by a gamma counter. The absorbed doses of organs were calculated as % ID/g. One-way analysis of variance was used. Results: After 4 d, inhibition rate of Patu8988 cell proliferation in the 188Re-IGF-1A group (1.85 MBq) was (90.75 ±5.20)%,higher than that in 188ReO4-group or IGF-1A group ((49.50±2.39)%, (23.00±4.21)%; F=554.724, P<0.01). At 3 d after treatment with different doses of 188Re-IGF-1A (1.85, 3.70, 7.40 MBq), floating cell ratios were (16.56 ± 0.95)%, (33.39 ±5.93)% and (43.76 ± 1.38)%, respectively. Apoptosis ratios in the floating cells treated by 188Re-IGF-1A (1.85, 3.70, 7.40 MBq) were (12.70±2.27)%, (17.80±1.51)% and (23.23 ±1.22)%, respectively. Distribution in tumors was (39.30 ± 17.98), (10.59 ± 9.39), (5.32 ± 1.53) and (5.30 ±2.28)% ID/g at the 15 min, 1 d, 3 d, and 5 d time points after intratumoral

    Clinical imaging techniques for diagnosing breast cancer mainly include X-ray mammography, ultrasound, and magnetic resonance imaging (MRI), which have respective drawbacks. Multiphoton microscopy (MPM) has become a potentially attractive optical technique to bridge the current gap in clinical utility. In this paper, MPM was used to image normal and ductal cancerous breast tissues, based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). Our results showed that MPM has the ability to exhibit the microstructure of normal breast tissue, ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) lesions at the molecular level comparable to histopathology. These findings indicate that, with integration of MPM into currently accepted clinical imaging system, it has the potential to make a real-time histological diagnosis of mammary ductal carcinoma in vivo.

    AIMS: To investigate the effect of deleted pancreatic cancer locus 4 (DPC4) gene transfection on biological behaviors of human colorectal carcinoma cells and the role of DPC4 gene in colorectal carcinogenesis.METHODS: PcDNA3.1-DPC4 plasmid was re-constructed by gene-recombination technology. SW620 cells, a human colorectal carcinoma cell line, were transfected with PcDNA3.1-DPC4 plasmid using lipofectamine transfecting technique. Transfected cells were selected with G418.Expression of Smad4 protein was detected in cells transfected with DPC4 gene by immunohistochemistry and Western blot. Biological characterristics of transfected cells were evaluated by population-doubling time and cloning efficiency. Alterations of percentage of S phage cells (S%) and apoptosis rate were determined by flowcytometry.RESULTS: PcDNA3.1-DPC4 plasmid was constructed successfully. SW620 cells transfected with PcDNA3.1-DPC4plasmid (DPC4+-SW620 cells) showed a strong intracellular expression of Smad4 protein, and the positive signal was localized in cytoplasm and nuclei, mainly in cytoplasm,where the expressions of Smad4 protein in SW620 cells transfected with PcDNA3.1 plasmid (PcDNA3.1-SW620 cells)and non-transfected SW620 cells (SW620 cells) were weaker than those in DPC4+-SW620 cells. The populationdoubling time in DPC4+-SW620 cells (116 h) was significantly longer than that in SW620 cells (31 h) and PcDNA3.1-Sw620 cells (29 h) (P<0.01). The cloning efficiencies of DPC4+-SW620 cells (12%) were markedly lower than those of SW620 cells (69%) and PcDNA3.1-Sw620 cells (67%) (P<0.01). Compared with SW620 cells and PcDNA3.1-Sw620 cells, the G0-G1% of DPC4+-SW620cells was obviously higher and the S% was markedly lower (P<0.05). Apoptosis rate of DPC4+-SW620 cells was significantly higher than that of SW620 cells and PcDNA3.1-SW620 cells.CONCLUSION: PcDNA3.1-DPC4 plasmid can be successfully re-constructed and stably transfected into human SW620 cells, thereby the cells can steadily

  13. Phase I study of oral S-1 and concurrent radiotherapy in patients with unresectable locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose: The primary objective of this study was to determine the maximum-tolerated dose (MTD) of S-1, an oral fluoropyrimidine derivative, with concurrent radiotherapy in patients with unresectable locally advanced pancreatic cancer. Methods and Materials: Patients with histopathologically proven, unresectable, locally advanced pancreatic cancer were eligible. Radiotherapy was delivered in 1.8 Gy daily fractions to a total dose of 50.4 Gy over 5.5 weeks. S-1 was administered orally twice a day from Day 1 to 14 and 22 to 35 at escalating doses from 60 to 80 mg/m2/day. Results: Sixteen patients were enrolled in this study. Three patients received S-1 at 60 mg/m2/day, 3 at 70 mg/m2/day, and 10 at 80 mg/m2/day. Though 1 patient at the final dose level (80 mg/m2/day) experienced a dose limiting toxicity (biliary infection with Grade 3 neutropenia), the MTD was not reached in this study. The most common toxicities were anorexia and leukocytopenia, with Grade 3 toxicity occurring in 31% and 6.3% of the patients, respectively. Conclusions: The recommended dose of S-1 with concurrent radiotherapy was determined to be 80 mg/m2/day from Day 1 to 14 and 22 to 35 in patients with locally advanced pancreatic cancer. Oral S-1 and radiotherapy is well tolerated and feasible and should be further investigated

    Objective: To synthesize 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid-1-Nal3-octreotide (DOTA-NOC) as a new generation of positron emitting radionuclide labeled somatostatin analogue, and perform 68Ga-DOTA-NOC micro PET imaging on CFPAC-1 pancreatic cancer bearing nude mice. Methods: Thirty-seven MBq (100 μl) GaCl3 and 20 μg DOTA-NOC were added into 20 μl hydroxyethyl piperazine ethanesulfonic acid (HEPES) solution (0.1 mmol/L, pH=5.0), and heated for 15 min at 95 ℃. The radiochemical purity and in vitro stability of 68Ga-DOTA-NOC were analyzed with HPLC. Fifteen normal BALB/c mice were injected with 3.7 MBq 68Ga-DOTA-NOC via tail vein, and the biodistribution in dissected organs were measured at 5, 15, 30, 60 and 120 min respectively after the injection. CFPAC-1 pancreatic cancer cells were co-incubated with 68Ga-DOTA-NOC and the specific uptake ability was calculated. 68Ga-DOTA-NOC was injected into nude mice bearing CFPAC-1 tumors via tail vain. Dynamic and static images were performed by micro PET. ROI was drawn to calculate the T/NT and access TAC in tumor and main organs. The expression of SSTR (1-5) in CFPAC-1 cells in vivo was observed by flow cytometry. The correlation between the expression of SSTR and the T/NT was analyzed by linear correlation analysis. Results: 68Ga-NOTA-NOC had high radiolabeling yield of (98.8± 1.0)% and stability. Biodistribution study demonstrated that the predominant uptake of 68Ga-DOTA-NOC was found in the kidneys ((11.20±0.32) %ID/g at 5 min and (4.11±0.21) %ID/g at 60 min, respectively). The pancreas, lungs and stomach also showed high uptake. 68Ga-DOTA-NOC could be specifically uptaken by CFPAC-1 cells with high affinity. T/NT of 68Ga-DOTA-NOC in CFPAC-1 cancer xenografts was 3.2 ± 0.2 at 120 min post-injection. SSTR 1, 2, 4, 5 expressed in CFPAC-1 cells and xenograft tissues were (96.83± 1.23)%, (99.73±0.98)%, (90.42±0.63)% and (92.96±0.71)%, respectively. The SSTR 2, 5 expression level and

  15. Optical characterization of lesions and identification of surgical margins in pancreatic metastasis from renal cell carcinoma by using two-photon excited fluorescence microscopy

    International Nuclear Information System (INIS)

    Two-photon excited fluorescence (TPEF) microscopy has become a powerful instrument for imaging unstained tissue samples in biomedical research. The purpose of this study was to determine whether TPEF imaging of histological sections without hematoxylin-eosin (H-E) stain can be used to characterize lesions and identify surgical margins in pancreatic metastasis from renal cell carcinoma (RCC). The specimens of a pancreatic metastasis from RCC, as well as a primary RCC from a patient, were examined by TPEF microscopy and compared with their corresponding H-E stained histopathological results. The results showed that high-resolution TPEF imaging of unstained histological sections of pancreatic metastasis from RCC can reveal that the typical morphology of the tissue and cells in cancer tissues is different from the normal pancreas. It also clearly presented histopathological features of the collagenous capsule, which is an important boundary symbol to identify normal and cancerous tissue and to instruct surgical operation. It indicated the feasibility of using TPEF microscopy to make an optical diagnosis of lesions and identify the surgical margins in pancreatic metastasis from RCC. (paper)

    Pluripotent stem cells (PSCs) are able to differentiate intoseveral cell types, including pancreatic β cells. Differentiationof pancreatic β cells depends on certain transcriptionfactors, which function in a coordinated way duringpancreas development. The existing protocols for in vitrodifferentiation produce pancreatic β cells, which are nothighly responsive to glucose stimulation except after theirtransplantation into immune-compromised mice and allowingseveral weeks for further differentiation to ensurethe maturation of these cells in vivo . Thus, although thesubstantial improvement that has been made for the differentiationof induced PSCs and embryonic stem cellstoward pancreatic β cells, several challenges still hinderingtheir full generation. Here, we summarize recent advancesin the differentiation of PSCs into pancreatic β cells anddiscuss the challenges facing their differentiation as wellas the different applications of these potential PSC-derivedβ cells.

    The progress in the development of systemic treatment for advanced pancreatic cancer (APC) has been slow. The mainstream treatment remains using chemotherapy including gemcitabine, FOLFIRINOX, and nab-paclitaxel. Erlotinib is the only approved biological therapy with marginal benefit. Studies of agents targeting epidermal growth factor receptor, angiogenesis, and RAS signaling have not been satisfying, and the usefulness of targeted therapy in APC is uncertain. Understanding in molecular processes and tumor biology has opened the door for new treatment strategies such as targeting insulin-like growth factor 1 receptor, transforming growth factor β, phosphoinositide 3-kinase/AKT/mammalian target of rapamycin pathway, and Notch pathway. New directions also include the upcoming immunotherapy and many novel agents that act on the microenvironment. The practice of personalized medicine using predictive biomarkers and pharmacogenomics signatures may also enhance the effectiveness of existing treatment. Future treatment approaches may involve comprehensive genomic assessment of tumor and integrated combinations of multiple agents to overcome treatment resistance. PMID:25117068

    Severe acute pancreatitis (AP) is responsible for significant human morbidity and mortality worldwide. Currently, no specific treatments for AP exist, primarily due to the lack of a mechanistic understanding of sterile inflammation and the resultant multisystem organ dysfunction, the pathologic response of AP linked to early death. In this study, we demonstrate that the class III major histocompatibility region III receptor for advanced glycation end products (RAGE) contributes to AP by modulating inflammasome activation in macrophages. RAGE mediated nucleosome-induced absent in melanoma 2 (but not NLRP3) inflammasome activation by modulating dsRNA-dependent protein kinase phosphorylation in macrophages. Pharmacological and genetic inhibition of the RAGE-dsRNA-dependent protein kinase pathway attenuated the release of inflammasome-dependent exosomal leaderless cytokines (e.g., IL-1β and high-mobility group box 1) in vitro. RAGE or absent in melanoma 2 depletion in mice limited tissue injury, reduced systemic inflammation, and protected against AP induced by l-arginine or cerulein in experimental animal models. These findings define a novel role for RAGE in the propagation of the innate immune response with activation of the nucleosome-mediated inflammasome and will help guide future development of therapeutic strategies to treat AP.

    The incidence of pancreatic ductal adenocarcinoma (PDA) is on the rise, and the prognosis is extremely poor because PDA is highly aggressive and notoriously difficult to treat. Although gemcitabine- or 5-fluorouracil-based chemotherapy is typically offered as a standard of care, most patients do not survive longer than 1 year. Therefore, the development of alternative therapeutic approaches for patients with PDA is imperative. As PDA cells express numerous tumor-associated antigens that are suitable vaccine targets, one promising treatment approach is cancer vaccines. During the last few decades, cell-based cancer vaccines have offered encouraging results in preclinical studies. Cell-based cancer vaccines are mainly generated by presenting whole tumor cells or dendritic cells to cells of the immune system. In particular, several clinical trials have explored cell-based cancer vaccines as a promising therapeutic approach for patients with PDA. Moreover, chemotherapy and cancer vaccines can synergize to result in increased efficacies in patients with PDA. In this review, we will discuss both the effect of cell-based cancer vaccines and advances in terms of future strategies of cancer vaccines for the treatment of PDA patients. PMID:27182156

  5. Phase II Study of Oral S-1 and Concurrent Radiotherapy in Patients With Unresectable Locally Advanced Pancreatic Cancer

    International Nuclear Information System (INIS)

    Purpose: S-1 is an oral fluoropyrimidine derivative that has demonstrated favorable antitumor activity in patients with metastatic pancreatic cancer. The aim of this study was to evaluate safety and efficacy of S-1 and concurrent radiotherapy in patients with unresectable locally advanced pancreatic cancer. Methods and Materials: Patients with histopathologically proven, unresectable, locally advanced pancreatic cancer were eligible. Radiotherapy was delivered in 1.8 Gy daily fractions to a total dose of 50.4 Gy over 5.5 weeks. S-1 was administered orally twice a day at a dose of 80 mg/m2/day from day 1 to 14 and 22 to 35. Two weeks after the completion of chemoradiotherapy, maintenance chemotherapy with S-1 was administered for 28 days every 6 weeks until progression. Results: Thirty-four patients were enrolled in this study. The most common Grade 3 toxicities during chemoradiotherapy were anorexia (24%) and nausea (12%). The overall response rate was 41% (95% confidence interval, 25%-58%) and overall disease control rate (partial response plus stable disease) was 97%. More than 50% decrease in serum CA 19-9 was seen in 27 of 29 evaluable patients (93%). The median progression-free survival was 8.7 months. The median overall survival and 1-year survival rate were 16.8 months and 70.6%, respectively. Conclusions: Oral S-1 and concurrent radiotherapy exerted a promising antitumor activity with acceptable toxicity in patients with locally advanced pancreatic cancer. This combination therapy seems to be an attractive alternative to conventional chemoradiotherapy using 5-fluorouracil infusion.

    Full Text Available AIM: To investigate the therapeutic efficacy and mechanisms of action of oncolytic-herpes-simplex-virus encoding granulocyte-macrophage colony-stimulating factor (HSVGM-CSF in pancreatic carcinoma. METHODS: Tumor blocks were homogenized in a sterile grinder in saline. The homogenate was injected into the right armpit of each mouse. After vaccination, the mice were randomly assigned into four groups: a control group, a high dose HSVGM-CSF group [1 × 107 plaque forming units (pfu/tumor], a medium dose HSVGM-CSF group (5 × 106 pfu/tumor and a low dose HSVGM-CSF group (5 × 105 pfu/tumor. After initiation of drug administration, body weights and tumor diameters were measured every 3 d. Fifteen days later, after decapitation of the animal by cervical dislocation, each tumor was isolated, weighed and stored in 10% formaldehyde solution. The drug effectiveness was evaluated according to the weight, volume and relative volume change of each tumor. Furthermore, GM-CSF protein levels in serum were assayed by enzyme-linked immunosorbent assays at 1, 2, 3 and 4 d after injection of HSVGM-CSF. RESULTS: Injection of the recombinant mouse HSV encoding GM-CSF resulted in a significant reduction in tumor growth compared to the control group, and dose-dependent effects were observed: the relative tumor proliferation rates of the low dose, medium dose and high dose groups on 15 d after injection were 45.5%, 55.2% and 65.5%, respectively. The inhibition rates of the tumor weights of the low, middle, and high dose groups were 41.4%, 46.7% and 50.5%, respectively. Furthermore, the production of GM-CSF was significantly increased in the mice infected with HSVGM-CSF. The increase in the GM-CSF level was more pronounced in the high dose group compared to the other two dose groups. CONCLUSION: Our study provides the first evidence that HSVGM-CSF could inhibit the growth of pancreatic cancer. The enhanced GM-CSF expression might be responsible for the phenomenon.

    Full Text Available Elena Verzoni, Paolo Grassi, Isabella Testa, Roberto Iacovelli, Pamela Biondani, Enrico Garanzini , Filippo De Braud, Giuseppe ProcopioDepartment of Medical Oncology 1, Fondazione IRCCS Istituto Nazionale Tumori, Milan, ItalyAbstract: Antiangiogenesis options have evolved rapidly in the last few years, with an increasing number of agents currently approved by the US Food and Drug Administration and European Medicines Agency. Angiogenesis inhibitors have been shown to be very effective for the treatment of metastatic renal cancer cell. Axitinib is a third-generation inhibitor of vascular endothelial growth factor receptor and is currently being developed for the treatment of various malignancies. The pharmacokinetic properties of axitinib may have a selective therapeutic effect, with minimal adverse reactions and enhanced safety. In a large Phase III study of previously treated patients with metastatic renal cell carcinoma, axitinib achieved a longer progression-free survival than sorafenib with an acceptable safety profile and good quality of life. This review focuses on the pharmacology, pharmacokinetics, and clinical activity of axitinib in the current treatment of renal cell carcinoma. The role of axitinib in the adjuvant and/or neoadjuvant setting needs to be evaluated in further clinical trials.Keywords: axitinib, renal cell carcinoma, vascular endothelial growth factor receptor, angiogenesis

  10. Planoepitheliale cell carcinoma arising from ampullopancreatic unit

    International Nuclear Information System (INIS)

    Background: We report a case of planoepitheliale cell carcinoma located in the ampulla of Vater. We report the surgical results and pathological findings of a patient with an ampullary planoepitheliale cell carcinoma. From what we know it is the first case with successful surgical treatment. Case Report: A 58-year-old woman who presented with jaundice and preoperative endoscopic and radiological procedures could not show whether the tumour was carcinoma planoepitheliale. The clinical presentation, biochemical, radiographic and endoscopic investigation pronounced advanced pancreatic adenocarcinoma. Results: We performed pancreaticoduodenectomy with curative intention. Histological examination revealed: planoepitheliale cell carcinoma of the ampullo-pancreatic unit. Conclusions: In conclusion, preoperative endoscopic and radiological evaluations can all prove insufficient to distinguish between benign and malignant tumour. Thus, for malignant tumours surgeons may be forced to perform extensive surgery. (authors)

    A case of locally advanced thymic carcinoma that was successfully resected with the great vessels after chemoradiation therapy is reported. A 57-year-old man with Masaoka stage III thymic carcinoma received two cycles of cisplatin/docetaxel and 60 Gy irradiation. The response was stable disease with 19% size reduction, and a radical resection with the ascending aorta and superior vena cava with the patient under circulatory arrest with the use of cardiopulmonary bypass was performed. The postoperative course was uneventful, and the patient has been free of disease for 28 months. Trimodality therapy with use of a cardiovascular surgical procedure might be a valuable option in locally advanced thymic carcinoma. PMID:27449450

  13. Pancreatitis. An update

    International Nuclear Information System (INIS)

    Acute and chronic pancreatitis are becoming increasingly more severe diseases in the western world with far-reaching consequences for the individual patient as well as the socioeconomic situation. This article gives an overview of the contribution of radiological imaging to the diagnostics and therapy of both forms of the disease. Acute pancreatitis can be subdivided into severe (20 %) and mild manifestations. The diagnostics should be performed with computed tomography (CT) or magnetic resonance imaging (MRI) for assessing necrosis or potential infections only in severe forms of pancreatitis. In chronic pancreatitis transabdominal ultrasound should initially be adequate for assessment of the pancreas. For the differential diagnosis between pancreatic carcinoma and chronic pancreatitis, MRI with magnetic resonance cholangiopancreatography (MRCP) followed by an endoscopic ultrasound-guided fine needle aspiration is the method of choice. For the primary diagnosis for acute and chronic pancreatitis ultrasound examination is the modality of first choice followed by radiological CT and MRI with MRCP examinations. (orig.)

    Anna Maria Ierardi

    2014-11-01

    Full Text Available Context There is little reported experience of irreversible electroporation (IRE of locally advanced pancreatic tumors (LAP. In literature, few data reported complications. In particular vascular vasoconstriction miming splenic infarcts in humans has never been found. Case report This report describes the onset of asymptomatic multiple little splenic perfusion defects after the treatment of a LAP localized in the boby tail portion of the pancreas with the application of five percutaneous probes for IRE, in a 79 year-old man. Splenic artery was regularly patent but entirely trapped in the tumor. Conclusion To the best of our knowledge, until now, no experience concerning percutaneous IRE of pancreatic cancer described that phenomenon. The cause could not be established with certainty and “vascular lock" may be a valid hypothesis. Additional studies are necessary to evaluate its frequency and its exact pathophysiological cause in humans.

    A heterogeneous group of uncommon neoplastic and non-neoplastic pancreatic pathologies exists that can mimic pancreatic adenocarcinoma. These "imitators" are unique and may demonstrate characteristic clinical and imaging features. Imaging characteristics of some of these diverse lesions are not well described in the literature, and erroneous diagnoses of these entities as pancreatic carcinoma may be responsible for unnecessary surgeries. Knowledge of these selected pancreatic pathologies is essential to facilitate optimal patient management. PMID:25063236

    Background The purpose of the study was to evaluate the role of neoadjuvant chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries in treating patients with advanced ovarian epithelial carcinoma.Methods Forty-two patients with advanced ovarian epithelial carcinoma (study group) were treated via the anterior branches of the bilateral internal iliac arteries after cytoreductive surgery and 7 courses of adjuvant platinum-based combination chemotherapy. Primary cytoreductive surgery was performed in 43 patients with advanced ovarian epithelial carcinoma (control group), and then followed by 8 courses of adjuvant platinum-based combination chemotherapy. The rate of optimal cytoreductive surgery, survival rate, blood loss during operation and operative time were investigated in the two groups. Statistical significance was asessed using Student's t test, the Chi-squre test and the log-rank test. Results In the study group, the rate of optimum debulking after platinum-based chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries was 71.43%(30/42) (χ2=10.06, P0.05).Conclusions Neoadjuvant platinum-based combination chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries is an alternative treatment for patients with advanced ovarian epithelial carcinoma, in whom the chance of optimal cytoreductive surgery is low. The treatment can reduce blood loss, decrease operative time, and increase the rate of optimal cytoreductive surgery; but the median survival can't be improved significantly.

    AIM: To investigate the specific mechanisms of intrinsic and acquired resistance to taxotere (TXT) in pancreatic adenocarcinoma (PAC). METHODS: MTT assay was used to detect the sensitivity of PAC cell line SUIT-2 and its sublines (S-007, S-013, S-020,S-028 and TXT selected SUIT-2 cell line, S2/TXT) to TXT.Mdr1 (P-gp), multidrug resistance associated protein (MRP), lung resistance protein (LRP) and β-tubulin isotype gene expressions were detected by RT-PCR. The functionality of P-gp and MRP was tested using their specific blocker verapamil ( Ver ) and indomethacin ( IMC ),respectively. The transporter activity of P-gp was also confirmed by Rhodamine 123 accumulation assay. RESULTS: S-020 and S2/TXT were found to be significantly resistant to TXT(19 and 9.5-fold to their parental cell line SUIT-2, respectively ). RT-PCR demonstrated strong expression of Mdr1 in these two cell lines, but weaker expression or no expression in other cells lines. MRP and LRP expressions were found in most of these cell lines. The TXT-resistance in S2-020 and S2/TXT could be reversed almost completely by Ver, but not by IMC. Flow cytometry showed that Ver increased the accumulation of Rhodamine-123 in these two cell lines. Compared with S-020 and SUIT-2,the levels of β-tubulin isotype II, III expreesions in S-2/TXTwere increased remarkably. CONCLUSION: The both intrinsic and acquired TXT-related drugresistance in these PAC cell lines is mainly mediated by P-gp, but had no relationship to MRP and LRP expressions.The increases of β-tubulin isotype II, III might be collateral changes that occur when the SUIT-2 cells are treated with TXT.

  3. Perineural Invasion in Pancreatic Cancer: Advanced Research in the Neuro-cancer Interactions

    2010-12-01

    Full Text Available Pancreatic Cancer (PCa is characterized by prominently local nerve alterations and perineural invasion (PNI, which frequently affects the extrapancreatic nerve plexus, causing severe pain and retropancreatic tumor extension. It precludes curative resection, promotes local recurrence, and at the last negatively influences the prognosis of patients. Recent research on PNI in PCa has revealed the critical involvement of numerous nerve- or cancer cell-derived molecules in vitro and in vivo. However, the mechanisms contributing to alteration and invasion of intrapancreatic nerves and the spread of cancer cells along extrapancreatic nerves in pancreatic cancer patients are still poorly understood. This review focuses on perineural invasion in pancreatic cancer and provides an outline of the characteristics and molecular mechanisms of perineural invasion in pancreatic cancer.

    Induction chemoradiotherapy (CRT) may down-stage locally advanced pancreatic tumors but secondary resections are unfrequent. However some responders' patients may benefit of a RO resection. Patients and methods. We report 18 resections among 29 locally advanced pancreatic cancers; 15 patients were treated with neo-adjuvant 5-FU-cisplatin based (13) or taxotere based (2 patients) chemoradiotherapy (45 Gy), and 3 patients without histologically proven adenocarcinoma were resected without any preoperative treatment. Results. The morbidity rate was 28% and the mortality rate was 7%; one patient died after resection (5.5%) and one died after exploration (9%). The RO resection rate was 50%. The median survival for the resected patients was not reached and the actuarial survival at 3 years was 59%. Two specimens showed no residual tumor and the two patients were alive at 15 and 46 months without recurrence; one specimen showed less than 10% viable tumoral cells and the patient was alive at 36 months without recurrence. A mesenteric infarction was the cause of a late death at 3 years in a disease free patient (radiation induced injury of the superior mesenteric artery). The median survival of the 11 non-resected patients was 21 months and the actuarial survival at 2 years was 0%. When the number of the resected patients (18) was reported to the entire cohort of the patients with locally advanced pancreatic cancer treated during the same period in our institution, the secondary resectability rate was 9%. Conclusion. Preoperative chemoradiotherapy identifies poor surgical candidates through observation and may enhance the margin status of patients undergoing secondary resection for locally advanced tumors. However it remains difficult to evaluate the results in the literature because of the variations in the definitions of resectability. The best therapeutic strategy remains to be defined, because the majority of patients ultimately succumb with distant metastatic

  6. Phase I study evaluating the treatment of patients with locally advanced pancreatic cancer with carbon ion radiotherapy: the PHOENIX-01 trial

    International Nuclear Information System (INIS)

    Treatment options for patients with locally advanced pancreatic cancer include surgery, chemotherapy as well as radiotherapy. In many cases, surgical resection is not possible, and therefore treatment alternatives have to be performed. Chemoradiation has been established as a convincing treatment alternative for locally advanced pancreatic cancer. Carbon ions offer physical and biological characteristics. Due to their inverted dose profile and the high local dose deposition within the Bragg peak precise dose application and sparing of normal tissue is possible. Moreover, in comparison to photons, carbon ions offer an increased relative biological effectiveness (RBE), which can be calculated between 1.16 and 2.46 depending on the pancreatic cancer cell line as well as the endpoint analyzed. Japanese Data on the evaluation of carbon ion radiation therapy showed promising results for patients with pancreatic cancer. The present PHOENIX-01 trial evaluates carbon ion radiotherapy using the active rasterscanning technique in patients with advanced pancreatic cancer in combination with weekly gemcitabine and adjuvant gemcitabine. Primary endpoint is toxicity, secondary endpoints are overall survival, progression-free survival and response. The physical and biological properties of the carbon ion beam promise to improve the therapeutic ratio in patients with pancreatic cancer: Due to the inverted dose profile dose deposition in the entry channel of the beam leads to sparing of normal tissue; the Bragg peak can be directed into the defined target volume, and the sharp dose fall-off thereafter again spares normal tissue behind the target volume. The higher RBE of carbon ions, which has been shown also for pancreatic cancer cell lines in the preclinical setting, is likely to contribute to an increase in local control, and perhaps in OS. Early data from Japanese centers have shown promising results. In conclusion, this is the first trial to evaluate actively delivered carbon

  7. Molecular Endoscopic Ultrasound for Diagnosis of Pancreatic Cancer

    International Nuclear Information System (INIS)

    Endoscopic ultrasound-guided fine needle aspiration-biopsy is a safe and effective technique in diagnosing and staging of pancreatic ductal adenocarcinoma. However its predictive negative value does not exceed 50% to 60%. Unfortunately, the majority of pancreatic cancer patients have a metastatic and/or a locally advanced disease (i.e., not eligible for curative resection) which explains the limited access to pancreatic tissue specimens. Endoscopic ultrasound-guided fine needle aspiration-biopsy is the most widely used approach for cytological and histological material sampling in these situations used in up to two thirds of patients with pancreatic cancer. Based on this unique material, we and others developed strategies to improve the differential diagnosis between carcinoma and inflammatory pancreatic lesions by analysis of KRAS oncogene mutation, microRNA expression and methylation, as well as mRNA expression using both qRT-PCR and Low Density Array Taqman analysis. Indeed, differentiating pancreatic cancer from pseudotumoral chronic pancreatitis remains very difficult in current clinical practice, and endoscopic ultrasound-guided fine needle aspiration-biopsy analysis proved to be very helpful. In this review, we will compile the clinical and molecular advantages of using endoscopic ultrasound-guided fine needle aspiration-biopsy in managing pancreatic cancer

    The main pancreatic duct has been visualized with both ultrasound and computed tomography. A normal pancreatic duct has been reported using CT, and controversy persists over whether a normal duct can be routinely imaged with ultrasound. The dilated pancreatic duct has always been associated with disease - usually pancreatitis or a proximal obstructing pancreatic carcinoma. In the patient with no clinical history or laboratory data suggesting pancreatitis, a dilated pancreatic duct implies a proximal tumor.

  13. Phase II trial of sorafenib and erlotinib in advanced pancreatic cancer

    International Nuclear Information System (INIS)

    This trial was designed to assess efficacy and safety of erlotinib with sorafenib in the treatment of patients with advanced pancreatic adenocarcinoma. An exploratory correlative study analyzing pretreatment serum samples using a multivariate protein mass spectrometry-based test (VeriStrat®), previously shown to correlate with outcomes in lung cancer patients treated with erlotinib, was performed. Patients received sorafenib 400 mg daily along with erlotinib 150 mg daily with a primary endpoint of 8-week progression free survival (PFS) rate. Pretreatment serum sample analysis by VeriStrat was done blinded to clinical and outcome data; the endpoints were PFS and overall survival (OS). Difference between groups (by VeriStrat classification) was assessed using log-rank P values; hazard ratios (HR) were obtained from Cox proportional hazards model. Thirty-six patients received study drug and were included in the survival analysis. Eight-week PFS rate of 46% (95% confidence interval (CI): 0.32–0.67) did not meet the primary endpoint of a rate ≥70%. Thirty-two patients were included in the correlative analysis, and VeriStrat “Good” patients had superior PFS (HR = 0.18, 95% CI: 0.06–0.57; P = 0.001) and OS (HR = 0.31 95% CI: 0.13–0.77, P = 0.008) compared to VeriStrat “Poor” patients. Grade 3 toxicities of this regimen included fever, anemia, diarrhea, dehydration, rash, and altered liver function. This study did not meet the primary endpoint, and this combination will not be further pursued. In this small retrospective analysis, the proteomic classification was significantly associated with clinical outcomes and is being further evaluated in ongoing studies

  14. Reverse-Contrast Imaging and Targeted Radiation Therapy of Advanced Pancreatic Cancer Models

    International Nuclear Information System (INIS)

    Purpose: To evaluate the feasibility of delivering experimental radiation therapy to tumors in the mouse pancreas. Imaging and treatment were performed using combined CT (computed tomography)/orthovoltage treatment with a rotating gantry. Methods and Materials: After intraperitoneal administration of radiopaque iodinated contrast, abdominal organ delineation was performed by x-ray CT. With this technique we delineated the pancreas and both orthotopic xenografts and genetically engineered disease. Computed tomographic imaging was validated by comparison with magnetic resonance imaging. Therapeutic radiation was delivered via a 1-cm diameter field. Selective x-ray radiation therapy of the noninvasively defined orthotopic mass was confirmed using γH2AX staining. Mice could tolerate a dose of 15 Gy when the field was centered on the pancreas tail, and treatment was delivered as a continuous 360° arc. This strategy was then used for radiation therapy planning for selective delivery of therapeutic x-ray radiation therapy to orthotopic tumors. Results: Tumor growth delay after 15 Gy was monitored, using CT and ultrasound to determine the tumor volume at various times after treatment. Our strategy enables the use of clinical radiation oncology approaches to treat experimental tumors in the pancreas of small animals for the first time. We demonstrate that delivery of 15 Gy from a rotating gantry minimizes background healthy tissue damage and significantly retards tumor growth. Conclusions: This advance permits evaluation of radiation planning and dosing parameters. Accurate noninvasive longitudinal imaging and monitoring of tumor progression and therapeutic response in preclinical models is now possible and can be expected to more effectively evaluate pancreatic cancer disease and therapeutic response

    Pancreatic cancer (PC) would become the second leading cause of cancer death in the near future, despite representing only 3% of new cancer diagnosis. Survival improvement will come from a better knowledge of risk factors, earlier diagnosis, better integration of locoregional and systemic therapies, as well as the development of more efficacious drugs rising from a deeper understanding of disease biology. For patients with unresectable, non-metastatic disease, combined strategies encompassing primary chemotherapy and radiation seems to be promising. In fit patients, new polychemotherapy regimens can lead to better outcomes in terms of slight but significant survival improvement associated with a positive impact on quality of life. The upfront use of these regimes can also increase the rate of radical resections in borderline resectable and locally advanced PC. Second line treatments showed to positively affect both overall survival and quality of life in fit patients affected by metastatic disease. At present, oxaliplatin-based regimens are the most extensively studied. Nonetheless, other promising drugs are currently under evaluation. Presently, in addition to surgery and conventional radiation therapy, new locoregional treatment techniques are emerging as alternative options in the multimodal approach to patients or diseases not suitable for radical surgery. As of today, in contrast with other types of cancer, targeted therapies failed to show relevant activity either alone or in combination with chemotherapy and, thus, current clinical practice does not include them. Up to now, despite the fact of extremely promising results in different tumors, also immunotherapy is not in the actual therapeutic armamentarium for PC. In the present paper, we provide a comprehensive review of the current state of the art of clinical practice and research in PC aiming to offer a guide for clinicians on the most relevant topics in the management of this disease.

  16. High-dose Helical Tomotherapy With Concurrent Full-dose Chemotherapy for Locally Advanced Pancreatic Cancer

    International Nuclear Information System (INIS)

    Purpose: To improve poor therapeutic outcome of current practice of chemoradiotherapy (CRT), high-dose helical tomotherapy (HT) with concurrent full-dose chemotherapy has been performed on patients with locally advanced pancreatic cancer (LAPC), and the results were analyzed. Methods and Materials: We retrospectively reviewed 39 patients with LAPC treated with radiotherapy using HT (median, 58.4 Gy; range, 50.8–59.9 Gy) and concomitant chemotherapy between 2006 and 2009. Radiotherapy was directed to the primary tumor with a 0.5-cm margin without prophylactic nodal coverage. Twenty-nine patients (79%) received full-dose (1000 mg/m2) gemcitabine-based chemotherapy during HT. After completion of CRT, maintenance chemotherapy was administered to 37 patients (95%). Results: The median follow-up was 15.5 months (range, 3.4–43.9) for the entire cohort, and 22.5 months (range, 12.0–43.9) for the surviving patients. The 1- and 2-year local progression-free survival rates were 82.1% and 77.3%, respectively. Eight patients (21%) were converted to resectable status, including 1 with a pathological complete response. The median overall survival and progression-free survival were 21.2 and 14.0 months, respectively. Acute toxicities were acceptable with no gastrointestinal (GI) toxicity higher than Grade 3. Severe late GI toxicity (≥Grade 3) occurred in 10 patients (26%); 1 treatment-related death from GI bleeding was observed. Conclusion: High-dose helical tomotherapy with concurrent full-dose chemotherapy resulted in improved local control and long-term survival in patients with LAPC. Future studies are needed to widen the therapeutic window by minimizing late GI toxicity.

  17. A treatment planning comparison of four target volume contouring guidelines for locally advanced pancreatic cancer radiotherapy

    International Nuclear Information System (INIS)

    Background and purpose: Contouring of target volumes varies significantly in radiotherapy of pancreatic ductal adenocarcinoma (PDAC). There is a lack of consensus as to whether elective lymph nodes (eLN’s) should be included or not in the planning target volume (PTV). In the present study we analyzed the dosimetric coverage of the eLN’s and organs at risk (OAR) by comparing four different contouring guidelines. Methods and materials: PTVs were delineated with (Oxford and RTOG guidelines) or without (Michigan and SCALOP guidelines) including the eLNs in eleven patients with PDAC. eLNs included the peripancreatic, paraaortic, paracaval, celiac trunk, superior mesenteric and portal vein clinical target volumes (CTVs). A 3D-CRT plan (50.40 Gy in 28 fractions) was performed to analyze and compare the dosimetric coverage of all eLNs and OAR between the 4 contouring guidelines. Results: The size of Oxford and RTOG PTVs was comparable and significantly larger than the SCALOP and Michigan PTVs. Interestingly the eLNs received a significant amount of incidental dose irradiation by PTV-based plans that only aimed to treat the tumor without the eLNs. The dosimetric coverage of eLN presented a large variability according to the respective contouring methods. The difference in the size of the 4 PTVs was reflected to the dose distribution at the OAR. Conclusions: Our study provides important information regarding the impact of different contouring guidelines on the dose distribution to the eLNs and the OAR in patients with locally advanced PDAC treated with radiotherapy

    Purpose: To evaluate the feasibility of delivering experimental radiation therapy to tumors in the mouse pancreas. Imaging and treatment were performed using combined CT (computed tomography)/orthovoltage treatment with a rotating gantry. Methods and Materials: After intraperitoneal administration of radiopaque iodinated contrast, abdominal organ delineation was performed by x-ray CT. With this technique we delineated the pancreas and both orthotopic xenografts and genetically engineered disease. Computed tomographic imaging was validated by comparison with magnetic resonance imaging. Therapeutic radiation was delivered via a 1-cm diameter field. Selective x-ray radiation therapy of the noninvasively defined orthotopic mass was confirmed using γH2AX staining. Mice could tolerate a dose of 15 Gy when the field was centered on the pancreas tail, and treatment was delivered as a continuous 360° arc. This strategy was then used for radiation therapy planning for selective delivery of therapeutic x-ray radiation therapy to orthotopic tumors. Results: Tumor growth delay after 15 Gy was monitored, using CT and ultrasound to determine the tumor volume at various times after treatment. Our strategy enables the use of clinical radiation oncology approaches to treat experimental tumors in the pancreas of small animals for the first time. We demonstrate that delivery of 15 Gy from a rotating gantry minimizes background healthy tissue damage and significantly retards tumor growth. Conclusions: This advance permits evaluation of radiation planning and dosing parameters. Accurate noninvasive longitudinal imaging and monitoring of tumor progression and therapeutic response in preclinical models is now possible and can be expected to more effectively evaluate pancreatic cancer disease and therapeutic response.

    The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Ma...

    A 81-old-woman underwent a transurethral resection of bladder tumor (TURBT) at a nearby hospital in April 2011. The diagnosis was invasive urothelial carcinoma, G3 with a component of bladder small cell carcinoma, T1 or more. She was recommended to visit our hospital for combined modality therapy of bladder cancer, but she refused the treatment for over one year. In May 2012, she came to our hospital with the chief complaint of pain at urination. Cystoscopy revealed non-papillary sessile tumor in the top of the bladder, and CT scan demonstrated the presence of the right obturator lymph nodes swollen up to 1.2 cm in size. The second TURBT was performed and the diagnosis was bladder small cell carcinoma (pT3N2M0) according to urothelial cancer guidelines of the Japanese Urological Association (JUA). Because she strongly refused hospitalization anymore, we started daily oral intake of low dose Tegafur-Uracil (100 mg) for the treatment. After one month, the serum Neuron-Specific Enolase (NSE; tumor maker of small cell cancer) level was elevated to 27.6 ng/ml and the right obturator lymph node was enlarged up to 1.9 cm. Therefore, the Trgafur-Uracil dose was increased to 200 mg daily. After then, the serum NSE level was decreased to 15.5 ng/ml following reduction in size of the obturator lymph nodes with partial response in December 2013. After two years of follow-up period, her regular urine test showed normal findings, and no apparent recurrence was detected on urinary bladder with MRI and Cystoscopy. This is a case of advanced bladder small cell carcinoma significantly improved by oral administration of Tegafur-Uracil 200 mg/day for over 2 years. PMID:26717786

    Full Text Available Hepatocellular carcinoma usually metastasizes to regional lymph nodes, lung, and bones but can rarely invade the inferior vena cava with intravascular extension to the right atrium. We present the case of a 75-year-old man who was admitted for generalized oedema and was found to have advanced HCC with invasion of the inferior vena cava and endovascular extension to the right atrium. In contrast to the great majority of hepatocellular carcinoma, which usually develops on the basis of liver cirrhosis due to identifiable risk factors, none of those factors were present in our patient.

    Full Text Available Betulin and betulinic acid are naturally occurring pentacyclic triterpenes showing cytotoxicity towards a number of cancer cell lines. These compounds can be found in the bark of the many plants. In this report we have compared the cytotoxic activity of crude birch bark extract and purified betulin and betulinic acid towards human gastric carcinoma (EPG85-257 and human pancreatic carcinoma (EPP85-181 drug-sensitive and drug-resistant (daunorubicin and mitoxantrone cell lines. Our results show significant differences in sensitivity between cell lines depending on the compound used, and suggest that both betulin and betulinic acid can be considered as a promising leads in the treatment of cancer.

  4. Inhibition of the mammalian target of rapamycin (mTOR) in advanced pancreatic cancer: results of two phase II studies

    International Nuclear Information System (INIS)

    The phosphoinositide 3-kinase (PI3K)/Akt pathway is constitutively activated in pancreatic cancer and the mammalian target of rapamycin (mTOR) kinase is an important mediator for its signaling. Our recent in vitro studies suggest that prolonged exposure of pancreatic cancer cells to mTOR inhibitors can promote insulin receptor substrate-PI3K interactions and paradoxically increase Akt phosphorylation and cyclin D1 expression in pancreatic cancer cells (negative feedback loop). The addition of erlotinib to rapamycin can down-regulate rapamycin-stimulated Akt and results in synergistic antitumor activity with erlotinib in preclinical tumor models. Two studies prospectively enrolled adult patients with advanced pancreatic cancer, Eastern Cooperative Oncology Group performance status 0-1, adequate hematologic, hepatic and renal parameters and measurable disease. In Study A, temsirolimus was administered intravenously at 25 mg weekly. In Study B, everolimus was administered orally at 30 mg weekly and erlotinib was administered at 150 mg daily. The primary endpoint in both studies was overall survival at 6 months. Secondary endpoints included time to progression, progression-free survival, overall survival, response rate, safety and toxicity. Pretreatment tumor biopsies were analyzed by immunofluorescence and laser scanning cytometry for the expression of pmTOR/mTOR, pAkt/Akt, pErk/Erk, pS6, p4EBP-1 and PTEN. Five patients enrolled in Study A; Two patients died within a month (rapid disease progression and hemorrhagic stroke, respectively). One patient developed dehydration and another developed asthenia.

  8. Pathologic response with neoadjuvant chemotherapy and stereotactic body radiotherapy for borderline resectable and locally-advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Neoadjuvant stereotactic body radiotherapy (SBRT) has potential applicability in the management of borderline resectable and locally-advanced pancreatic adenocarcinoma. In this series, we report the pathologic outcomes in the subset of patients who underwent surgery after neoadjuvant SBRT. Patients with borderline resectable or locally-advanced pancreatic adenocarcinoma who were treated with SBRT followed by resection were included. Chemotherapy was to the discretion of the medical oncologist and preceded SBRT for most patients. Twelve patients met inclusion criteria. Most (92%) received neoadjuvant chemotherapy, and gemcitabine/capecitabine was most frequently utilized (n = 7). Most were treated with fractionated SBRT to 36 Gy/3 fractions (n = 7) and the remainder with single fraction to 24 Gy (n = 5). No grade 3+ acute toxicities attributable to SBRT were found. Two patients developed post-surgical vascular complications and one died secondary to this. The mean time to surgery after SBRT was 3.3 months. An R0 resection was performed in 92% of patients (n = 11/12). In 25% (n = 3/12) of patients, a complete pathologic response was achieved, and an additional 16.7% (n = 2/12) demonstrated <10% viable tumor cells. Kaplan-Meier estimated median progression free survival is 27.4 months. Overall survival is 92%, 64% and 51% at 1-, 2-, and 3-years. This study reports the pathologic response in patients treated with neoadjuvant chemotherapy and SBRT for borderline resectable and locally-advanced pancreatic cancer. In our experience, 92% achieved an R0 resection and 41.7% of patients demonstrated either complete or extensive pathologic response to treatment. The results of a phase II study of this novel approach will be forthcoming

    Hepatocellular carcinoma (HCC) is one of the most lethal malignancies worldwide. Early-stage HCC can be curatively treated, but the recurrence rate remains high. To date, adjuvant treatments have not proven effective in preventing HCC recurrence after curative treatment. Although early studies explored the potential of vitamin K2, retinoid, chemotherapy, and recently, sorafenib, none of the studies reported successful outcomes. Several new lines of evidence have emerged to support the use of novel antiviral agents for preventing the recurrence of virus-related HCC after curative treatment. In this review, the authors provide a thorough overview of the various adjuvant treatments that have been attempted or are being considered for trial. PMID:25369304

    Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

  11. Pancreatic cancer accompanied by a moderate-sized pseudocyst with extrapancreatic growth

    International Nuclear Information System (INIS)

    Pancreatic cancer accompanied by a moderate-sized pseudocyst with extrapancreatic growth is extremely rare. Diagnosis of pancreatic cancer on preoperative imaging is difficult when the pancreatic parenchyma is compressed by a pseudocyst and becomes unclear. Despite advances in imaging techniques, accurate preoperative diagnosis of cystic lesions of the pancreas remains difficult. In this case, it was challenging to diagnose pancreatic cancer preoperatively as we could not accurately assess the pancreatic parenchyma, which had been compressed by a moderate-sized cystic lesion with extrapancreatic growth. A 63-year-old woman underwent investigations for epigastric abdominal pain. She had no history of pancreatitis. Although we suspected pancreatic ductal carcinoma with a pancreatic cyst, there was no mass lesion or low-density area suggestive of pancreatic cancer. We did not immediately suspect pancreatic cancer, as development of a moderate-sized cyst with extrapancreatic growth is extremely rare and known tumor markers were not elevated. Therefore, we initially suspected that a massive benign cyst (mucinous cyst neoplasm, serous cyst neoplasm, or intraductal papillary mucinous neoplasm) resulted in stenosis of the main pancreatic duct. We were unable to reach a definitive diagnosis prior to the operation. We had planned a pancreaticoduodenectomy to reach a definitive diagnosis. However, we could not remove the tumor because of significant invasion of the surrounding tissue (portal vein, superior mesenteric vein, etc.). The fluid content of the cyst was serous, and aspiration cytology from the pancreatic cyst was Class III (no malignancy), but the surrounding white connective tissue samples were positive for pancreatic adenocarcinoma on pathological examination during surgery. We repeated imaging (CT, MRI, endoscopic ultrasound, etc.) postoperatively, but there were neither mass lesions nor a low-density area suggestive of pancreatic cancer. In retrospect, we think

    International Nuclear Information System (INIS)

    Of 38 patients with esophageal carcinoma who were treated at the Department of Radiology, Tokushima University Hospital between 1983 and 1987, 13 (34 %) received a combination of radiation and chemotherapy of cisplatin-based combination regimens. Twelve patients with squamous cell carcinoma and one with adenocarcinoma were treated by a 6 MV linear accelerater. They received a cummulative dose ranging from 18 to 68 Gy (average dose : 50.5 Gy), in 2 Gy fractions. The response rate was 62 % (CR 1, PR 7). Two of the six patients with Stage III survived more than three years. Median survival time was 11.4 months for patients with Stage III and 4.7 months for Stage IV. Chemotherapy improved median survival duration for patients with advanced esophageal carcinoma but did not produce a significant improvement in survival, as reported in other recent series. (author)

    International Nuclear Information System (INIS)

    Objective: To discuss the clinical efficacy of CT-guided radioactive 125I seed implantation treatment for unresectable pancreatic cancer. Methods: Forty patients with inoperable pancreatic cancer were enrolled in this study, including 25 males and 15 females with an median age of 69 years (38-89 years). Treatment planning system (TPS) was used to reconstruct 3-dimensional images of pancreatic tumor and to define the quantity and distribution of 125I seeds. The radioactivity of 125I seeds was 0.5 - 0.8 mCi / seed. The seeds were implanted into pancreatic tumor under CT guidance at intervals of 1 cm and were kept away from vessels, pancreatic duct and other adjacent important organs. The tumor matched peripheral dose (MPD) was 60-140 Gy. The median amount of implanted 125I seeds was 36 (18-68) in number. CT scan was performed immediately after the procedure to check the quality of the seeds. In addition, 10 patients received concurrent chemotherapy with arterial infusion of gemcitabin and 5-fluororacil (5-Fu) for 3 to 4 therapeutic courses. Results: The median diameter of the tumors was 4.9 cm. The follow-up period was 2 to 28 months. After the treatment the refractory pain was significantly relieved (P 125I seed implantation is a safe, effective and minimally-invasive brachytherapy for unresectable pancreatic cancer with reliable short-term efficacy. It has an excellent anti-pain effect. The curative results can be further improved when chemotherapy is employed together. However, its long-term efficacy needs to be observed. (authors)

  15. Perfusion CT in patients with advanced bronchial carcinomas: a novel chance for characterization and treatment monitoring?

    International Nuclear Information System (INIS)

    Advanced bronchial carcinomas by means of perfusion and peak enhancement using dynamic contrast-enhanced multislice CT are characterized. Twenty-four patients with advanced bronchial carcinoma were examined. During breathhold, after injection of a contrast-medium (CM), 25 scans were performed (1 scan/s) at a fixed table position. Density-time curves were evaluated from regions of interest of the whole tumor and high- and low-enhancing tumor areas. Perfusion and peak enhancement were calculated using the maximum-slope method of Miles and compared with size, localization (central or peripheral) and histology. Perfusion of large tumors (>50 cm3) averaged over both the whole tumor (P=0.001) and the highest enhancing area (P=0.003) was significantly lower than that of smaller ones. Independent of size, central carcinomas had a significantly (P=0.04) lower perfusion (mean 27.9 ml/min/100 g) than peripheral ones (mean 66.5 ml/min/100 g). In contrast, peak enhancement of central and peripheral carcinomas was not significantly different. Between non-small-cell lung cancers and small-cell lung cancers, no significant differences were observed in both parameters. In seven tumors, density increase after CM administration started earlier than in the aorta, indicating considerable blood supply from pulmonary vessels. Tumor perfusion was dependent on tumor size and localization, but not on histology. Furthermore, perfusion CT disclosed blood supply from both pulmonary and/or bronchial vessels in some tumors.

    Full Text Available The current standard of care for metastatic urothelial carcinoma (UC is cisplatin-based chemotherapy but treatment is generally not curative. Mechanisms of resistance to conventional cytotoxic regimens include tumor cell drug efflux pumps, intracellular anti-oxidants and enhanced anti-apoptotic signaling. Blockade of signaling pathways with small molecule tyrosine kinase inhibitors has produced dramatic responses in subsets of other cancers. Multiple potential signaling pathway targets are altered in UC. Blockade of the PI3K/Akt/mTOR pathway may prove efficacious because 21% have activating PI3K mutations and another 30% have PTEN inactivation (which leads to activation of this pathway. The fibroblast growth factor receptor 3 protein may be overactive in 50-60% and agents which block this pathway are under active development. Blockade of multiple other pathways including HER2 and aurora kinase also have potential efficacy. Anti-angiogenic and immunotherapy strategies are also under development in UC and are discussed in this review. Novel therapeutic approaches are needed in UC. We review the various strategies under development in this disease and discuss how best to evaluate and optimize their efficacy.

    Full Text Available In the present study, we observed that the adenocarcinoma component in the mucosa was continuous with neuroendocrine carcinoma (NEC in the deeper layers; this suggests the normal course of NEC carcinogenesis at the histological level. A 72-year-old man was admitted to our hospital with a chief complaint of tarry stools. Endoscopic examination of the upper gastrointestinal tract revealed a 2-cm tumor, with a deep central depression, surrounded by a smooth elevated area, in the middle of the stomach body. A biopsy showed that the tumor was a moderately differentiated gastric adenocarcinoma. The patient underwent total gastrectomy and standard lymph node dissection. The resected tumor was a 3.5 × 2.5 cm type 2 lesion. It comprised two elements at the histological level: (i a moderately differentiated adenocarcinoma in the superficial portion of the mucous membrane layer, and (ii NEC-like cells with dark, round nuclei and scant cytoplasm, presenting a solid and trabecular pattern, in the submucosal and muscularis propria layers. Immunohistochemical findings showed that the NEC-like cells were diffusely positive for chromogranin A, synaptophysin, neural cell adhesion molecule, and neuron-specific enolase, but were negative for carcinoembryonic antigen. The Ki-67 labeling index was 95%. The final pathological diagnosis was gastric NEC with an adenocarcinoma component and a high cellular proliferative potential.

    Functionally, the pancreas consists of two types of tissues: exocrine and endocrine. Exocrine pancreatic disorders mainly involve acute and chronic pancreatitis. Acute pancreatitis typically is benign, while chronic pancreatitis is considered a risk factor for developing pancreatic cancer. Pancreatic carcinoma is the fourth leading cause of cancer related deaths worldwide. Most pancreatic cancers develop in the exocrine tissues. Endocrine pancreatic tumors are more uncommon, and typically are less aggressive than exocrine tumors. However, the endocrine pancreatic disorder, diabetes, is a dominant cause of morbidity and mortality. Importantly, different growth factors and their receptors play critical roles in pancreatic pathogenesis. Hence, an improved understanding of how various growth factors affect pancreatitis and pancreatic carcinoma is necessary to determine appropriate treatment. This chapter describes the role of different growth factors such as vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), platelet derived growth factor (PDGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), and transforming growth factor (TGF) in various pancreatic pathophysiologies. Finally, the crosstalk between different growth factor axes and their respective signaling mechanisms, which are involved in pancreatitis and pancreatic carcinoma, are also discussed.

    Full Text Available Palliative care ought to be offered at the initiation of treatment for people who are diagnosed with pancreatic cancer, given the poor relative survival rate and the intractable symptom profile of those who have this life-limiting disease. In this article, we argue that palliative treatment of people with pancreatic cancer is not found in extending survival, but rather, in promoting quality of life. This argument is made by reviewing the literature on the state of palliative care in pancreatic cancer and by summarizing key studies presented at the “2010 ASCO Gastrointestinal Cancers Symposium” held in Orlando, FL, USA on January 22-24, 2010. The studies discussed here include: i a study of a random sample of 564 patients with pancreatic cancer that found that the symptom cluster of fatigue and pain predicted survival (Abstract #265; ii a retrospective study of 108 patients that identified anticoagulation therapy in those who developed portal vein thrombosis prolonged survival (Abstract #143; iii a double-blind randomized control trial of 50 patients with gastrointestinal cancers who were cachexic in which a thalidomide-olanzapine-megasterol acetate combination attenuated the effects of cancer-anorexia-cachexia syndrome (Abstract #209; iv a retrospective study on the role of adjuvant chemoradiation and chemotherapy in the treatment of advanced pancreatic cancer (Abstract #230; and v the benefit of chemotherapy in patients with metastatic pancreatic cancer 80-year-old or more (Abstract #232. Based on the results presented at the meeting, we believe that the discussion of palliative care in the treatment of advanced pancreatic cancer must not conflate the notion of increased survival with increased quality of life, the latter of which is part and parcel of the goal of palliative care. We believe that future study on the effect on quality of life of early palliative-care interventions among people with pancreatic cancer is necessary

    Pancreatic panniculitis is an inflammation and necrosis of fat at distant foci in patients with pancreatic disorders, most frequently, pancreatitis and pancreatic carcinoma. Clinically, pancreatic panniculitis is manifested by painless or painful subcutaneous nodules on the legs, buttocks, or trunk. The usual sites are the distal parts of the lower extremities. To the best of our knowledge, there have not been many reports for the radiologic findings of pancreatic panniculitis. In this article, we report a case of pancreatic panniculitis, including radiologic findings of CT and ultrasonography. The patient was presented with painful subcutaneous nodules on the trunk, and had underlying acute pancreatitis and hemorrhagic pseudocysts.

  2. Angiographic diagnosis and differentiation of pancreatic tumours

    International Nuclear Information System (INIS)

    In an 8-year period (1971-1978) 92 patients were examined because of suspected pancreatic tumour and the following symptoms were found: in 13 cases (14.1%) inoperable pancreatic carcinoma, in 2 cases insuloma, in 5 patients pancreatic cyst, in 5 cases pancreatitis, in one patient pancreatic abscess and in 12 cases alterations in the environing organs. The observed angiographic symptoms are described in detail. Except the richly vascularized tumour grown together with the stomach all pancreatic carcinomas were poor in vessels and they caused tumourous invasions in the greater arteries. The obliteration of the lienal vein, as well as the development of mesenteric venous collateral circulation signify an inoperable stage. The signs of the differential diagnosis of the pancreatitis and the carcinoma are dealt with in detail. In case of secondary pancreatic tumours - not even detectable by post-mortem examination - the angiographic signs are to be taken into consideration. (author)

    2011-12-01

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

    Neoadjuvant approaches in renal cell carcinoma are currently under investigation, following the demonstration of targeted therapy efficacy in the metastatic setting. It raises the issues of downsizing locally advanced or nonresectable tumor and offering organ-sparing surgery, safety and its potential role in early micrometastatic disease. Relevant studies of the neoadjuvant setting in renal cell carcinoma with targeted therapies were identified from the literature, clinical trial databases and conference abstracts. To date, a neoadjuvant approach appears feasible in terms of safety. Currently available drugs do not achieve major tumor downsizing with primary tumor diameters response rate of 10%. Neoadjuvants should only be considered in clinical trials or as a litmus test in locally advanced patients. PMID:23253222

    International Nuclear Information System (INIS)

    Objective: To summarize the author's experience which was obtained in observing and nursing the adverse reactions of advanced hepatocellular carcinoma patients who were treated with Sorafenib. Methods: The adverse reactions and their severity observed in 34 patients with advanced hepatocellular carcinoma who were treated with Sorafenib were retrospectively analyzed. Results: Side effects or toxic reaction were observed in all the patients, which included neutropenia, foot-hand syndrome (FHS), fatigue, diarrhea, hypertention, rash, etc. Five patients had to cut down the dose of Sorafenib in order to relieve the symptom, among them one patient had grade 4 FHS, 3 patients had grade 3 FHS and one patient had grade 3 neutropenia. Conclusion: Being familiar with sorafenib's adverse reaction, closely observing the patients condition and affording appropriate nursing measures, all the above items can definitely improve the therapeutic results and patient's living quality.

    1985-07-01

    Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma.

  9. Stereotactic Body Radiation Therapy for Locally Advanced and Borderline Resectable Pancreatic Cancer Is Effective and Well Tolerated

    International Nuclear Information System (INIS)

    Purpose: Stereotactic body radiation therapy (SBRT) provides high rates of local control (LC) and margin-negative (R0) resections for locally advanced pancreatic cancer (LAPC) and borderline resectable pancreatic cancer (BRPC), respectively, with minimal toxicity. Methods and Materials: A single-institution retrospective review was performed for patients with nonmetastatic pancreatic cancer treated with induction chemotherapy followed by SBRT. SBRT was delivered over 5 consecutive fractions using a dose painting technique including 7-10 Gy/fraction to the region of vessel abutment or encasement and 5-6 Gy/fraction to the remainder of the tumor. Restaging scans were performed at 4 weeks, and resectable patients were considered for resection. The primary endpoints were overall survival (OS) and progression-free survival (PFS). Results: Seventy-three patients were evaluated, with a median follow-up time of 10.5 months. Median doses of 35 Gy and 25 Gy were delivered to the region of vessel involvement and the remainder of the tumor, respectively. Thirty-two BRPC patients (56.1%) underwent surgery, with 31 undergoing an R0 resection (96.9%). The median OS, 1-year OS, median PFS, and 1-year PFS for BRPC versus LAPC patients was 16.4 months versus 15 months, 72.2% versus 68.1%, 9.7 versus 9.8 months, and 42.8% versus 41%, respectively (all P>.10). BRPC patients who underwent R0 resection had improved median OS (19.3 vs 12.3 months; P=.03), 1-year OS (84.2% vs 58.3%; P=.03), and 1-year PFS (56.5% vs 25.0%; P<.0001), respectively, compared with all nonsurgical patients. The 1-year LC in nonsurgical patients was 81%. We did not observe acute grade ≥3 toxicity, and late grade ≥3 toxicity was minimal (5.3%). Conclusions: SBRT safely facilitates margin-negative resection in patients with BRPC pancreatic cancer while maintaining a high rate of LC in unresectable patients. These data support the expanded implementation of SBRT for pancreatic cancer

    Sorafenib is the first and only orally administered drug currently approved to treat advanced hepatocellular carcinoma (HCC). However, concerns have been raised about sorafenib therapy, including acquired drug resistance. This review provides an overview of sorafenib in the treatment of HCC on the basis of data obtained in the laboratory and in clinical studies. Three underlying mechanisms have been found to support sorafenib therapy. First, sorafenib blocks HCC cell proliferation by inhibiti...

  11. Cost-effectiveness of sorafenib versus SBRT for unresectable advanced hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Stereotactic body radiotherapy (SBRT) has been shown to improve overall survival in patients with advanced hepatocellular carcinoma. This study aimed to assess the cost-effectiveness of SBRT compared to sorafenib which is the only drug for advanced hepatocellular carcinoma. A Markov decision-analytic model was performed to compare the cost-effectiveness of SBRT and sorafenib for unresectable advanced hepatocellular carcinoma. Patients transitioned between three health states: stable disease, progression disease and death. We calculated the data on cost from the perspective of our National Health Insurance Bureau. Sensitivity analyses were conducted to determine the impact of several variables. The incremental cost effectiveness ratio (ICER) for sorafenib compared to SBRT was NT$3,788,238 per quality-adjusted life year gained (cost/QALY), which was higher than the willingness to pay threshold of Taiwan according to WHO’s guideline. One-way sensitivity analysis revealed that the utility of progression disease for the sorafenib treatment, utility of progression free survival for SBRT, utility of progression free survival for sorafenib, utility of PFS to progression disease for SBRT and transition probability of progression disease to dead for SBRT were the most sensitive parameters in all cost scenarios. The Monte-Carlo simulation demonstrated that the probability of cost-effectiveness at a willingness to pay threshold of NT$ 2,213,145 per QALY was 100 % and 0 % chance for SBRT and sorafenib. This study indicated that SBRT for advanced hepatocellular carcinoma is cost-effective at a willingness to pay threshold as defined by WHO guideline in Taiwan

    Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, including Japan. Although the development of imaging modalities has made the early diagnosis of HCC possible, surgically resectable cases are relatively uncommon because of hepatic function reserve and/or an advanced stage at presentation. Several modalities, such as transcatheter arterial chemoembolization, percutaneous ethanol injection, microwave coagulation therapy and radiofrequency ablation are reportedly u...

    Purpose: To assess the toxicity profile of erlotinib therapy combined with postoperative adjuvant radiation therapy in patients with advanced cutaneous squamous cell carcinoma. Methods and Materials: This was a single-arm, prospective, phase 1 open-label study of erlotinib with radiation therapy to treat 15 patients with advanced cutaneous head-and-neck squamous cell carcinoma. Toxicity data were summarized, and survival was analyzed with the Kaplan-Meier method. Results: The majority of patients were male (87%) and presented with T4 disease (93%). The most common toxicity attributed to erlotinib was a grade 2-3 dermatologic reaction occurring in 100% of the patients, followed by mucositis (87%). Diarrhea occurred in 20% of the patients. The 2-year recurrence rate was 26.7%, and mean time to cancer recurrence was 10.5 months. Two-year overall survival was 65%, and disease-free survival was 60%. Conclusions: Erlotinib and radiation therapy had an acceptable toxicity profile in patients with advanced cutaneous squamous cell carcinoma. The disease-free survival in this cohort was comparable to that in historical controls.

    Objective: To assess the efficacy of PDT to: Palliate symptoms, control disease and extend survival in patients with advanced inoperable cancer. Subject and Method: 55 Males and 23 females aged between 45-81 years (mean 66 years) with inoperable and advanced lung cancer with > 5O. obstructive lesions of the main, lobar or segmental bronchi. Patients had pre-treatment routine clinical radiological, functional and endoscopic assessment with proven histological diagnosis. Protocol of PDT was; Intravenous injection of 2 mg/Kg bodyweight Polyhaematoporphyrin (equivalent to Photofrin) or Photofrin followed 24-72 hours later by illumination of tumour using 630 nm light (Oxford Laser) delivered via an optical fibre with end diffuser. Treatments were carried out under general anaesthesia as a day case procedure. Patients were rebronchoscoped for debridement/retreatment 4-7 days later. Results: There was no treatment related mortality. Two patients developed mild photosensitivity reaction. All patients showed symptomatic improvement with good initial functional and radiological amelioration. Every patient responded to treatment. Seven patients had complete response and negative histology for 3-12 months. After the first treatment average Forced Vital Capacity (FVC) and Forced Expiratory Volume in one second (FEV1) improvement was 0.5 litres and 0.4 litres respectively. Twenty five percent of patients (nr 19) survived more than 2 years, 10'. (nr=8) between 1-2 years and the remaining 51 patients less than a year. Conclusion: PDT should be considered as a therapeutic modality for all stages of lung cancer and is an excellent treatment modality for palliation in advanced bronchial malignancies.

    Full Text Available BACKGROUND : In India it is observed that most of the patients of breast cancer clinically present in late stage due to their ignorance of disease despite so much advancement in its detection and management. Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. This study aims to evaluate C linical features, Investigations, various Treatment modalities and the Clinico - pathological correlation & outcome of various treatment modalities of LABC, with special emphasis on Neo - adjuvant chemotherapy (NACT in Indian setting. MATERIAL AND METHOD : This was a non - randomised prospective observational study. We analyzed 57 patients of LABC Stage IIIB & IIIC presenting at Government Medical College, Nagpur, Maharashtra, a tertiary care C entre from September 2012 to November 2014. RESULTS : Stage IIIB comprised 84.21% patients while remaining 15.79% were having Stage IIIC disease. Skin involvement was observed in 91.23% patients. 15.79% showed supraclavicular lymph node involvement. 32 patients received NACT (2 to 6 cycles. Out of these 32, complete clinical response (cCR was 12.5%, partial response (cPR was 68.75% and pathological CR (pCR was 6.25% with Total Objective response (cCR+cPR 81.25%. Feasibility of Breast Conserving Surgery (BCS was observed in 12.5% patients. 25 patients underwent primary surgery followed by adjuvant chemotherapy. Modified Radical Mastectomy was performed in 89.48% patients. CONCLUSIONS : With overall clinical response of 81.25%, n eoadjuvant chemotherapy is the best treatment option for patients with Locally Advanced Breast Cancer with added advantage of in vivo testing the sensitivity of chemotherapeutic agents, early management of micrometastasis and down staging the primary tumour with feasibility of BCS. Patients presenting LABC constitute a diverse group for whic h a variety of treatment modalities should be instituted with co o rdinated treatment planning among surgeons

    International Nuclear Information System (INIS)

    Renal cell carcinoma (RCC) is rare in children and comprises only 1-3% of all pediatric primary renal tumors. Recently, several case reports have described RCC developing in patients previously treated for advanced stage neuroblastoma (NB). Our experience with four patients treated for advanced stage NB during early childhood who developed RCC later in life are added to 14 others in the literature. These patients and our review of the literature suggest an association between RCC and NB that warrants further study. (orig.)

    Full Text Available A 68-year-old male patient was referred to our institution in May 2011 for a suspected tumor in the pancreatic head with consecutive jaundice. Using magnetic resonance imaging, further differentiation between chronic inflammation and a malignant process was not possible with certainty. Apart from cholestasis, laboratory studies showed increased values for CA 19-9 to 532 U/ml (normal <37 U/ml and hypergammaglobulinemia (immunoglobulin G, IgG of 19.3% (normal 8.0–15.8% with an elevation of the IgG4 subtype to 2,350 mg/l (normal 52–1,250 mg/l. Endoscopic retrograde cholangiopancreatography revealed a prominent stenosis of the distal ductus hepaticus communis caused by pancreatic head swelling and also a bihilar stenosis of the main hepatic bile ducts. Cytology demonstrated inflammatory cells without evidence of malignancy. Under suspicion of autoimmune pancreatitis with IgG4-associated cholangitis, immunosuppressive therapy with steroids and azathioprine was started. Follow-up endoscopic retrograde cholangiopancreatography after 3 months displayed regressive development of the diverse stenoses. Jaundice had disappeared and blood values had returned to normal ranges. Moreover, no tumor of the pancreatic head was present in the magnetic resonance control images. Due to clinical and radiological similarities but a consecutive completely different prognosis and therapy, it is of fundamental importance to differentiate between pancreatic cancer and autoimmune pancreatitis. Especially, determination of serum IgG4 levels and associated bile duct lesions induced by inflammation should clarify the diagnosis of autoimmune pancreatitis and legitimate immunosuppressive therapy.

    Background Neoadjuvant chemoradiation is now considered the standard care for locally advanced rectal carcinoma (T3-4 or/and N1-2 lesions), but the accuracy of staging examinations including endorectal ultrasonography (ERUS) and MRI is far from excellent. In addition, the above staging equipment or professionals who perform the examinations may not be available in some hospitals, while preoperative colonoscopy and biopsy are usually obtainable in most hospitals.The objective of the present study was to investigate the clinical and pathological characteristics of locally advanced rectal carcinoma and identify candidates for neoadjuvant chemoradiation.Methods This was a retrospective study. Patients who were treated for rectal cancer at Changhai Hospital from January 1999 to July 2008 were identified from our prospectively collected database. Statistical analysis was performed using SPSS Software System (version 15.0). The Mann-Whitney test, chi-square test and multivariate Logistic regression analysis were performed,Results A total of 1005 cases were included in this research, of which 761 cases were identified as locally advanced rectal carcinoma depending on postoperative TNM staging. The results of multivariate Logistic regression analysis indicated seven independent risk factors that could be used to predict a locally advanced rectal carcinoma independently: a high grade (including poor differentiation and undifferentiation) (OR: 3.856; 95% CI: 2.064 to 7.204;P=0.000); large tumor size (OR: 2.455; 95% CI: 1.755 to 3.436; P=0.000); elevated preoperative serum CEA level (OR:1.823; 95% CI: 1.309 to 2.537; P=0.000); non-polypoid tumor type (OR: 1.758; 95% CI: 1.273 to 2.427; P=0.001); the absence of synchronous polyps (OR: 1.602; 95% CI: 1.103 to 2.327; P=0.013); the absence of blood in stool (OR: 1.659;95% CI: 1.049 to 2.624; P=0.030); and a greater circumferential tumor extent (OR: 1.813; 95% CI: 1.055 to 3,113;P=0.031). Based on these findings, a Logistic

  20. Therapy of pancreatic cancer

    International Nuclear Information System (INIS)

    Pancreatic cancer remains one of the most difficult diseases to cure. Japan pancreas society guidelines for management of pancreatic cancer indicate therapeutic algorithm according to the clinical stage. For locally limited pancreatic cancer (cStage I, II, III in Japanese classification system), surgical resection is recommended, however prognosis is still poor. Major randomized controlled trials of resected pancreatic cancer indicates that adjuvant chemotherapy is superior to observation and gemcitabine is superior to 5-fluorouracil (FU). For locally advanced resectable pancreatic cancer (cStage IVa in Japanese classification system (JCS)), we perform neoadjuvant chemoradiotherapy. Phase I study established a recommended dose of 800 mg gemcitabine and radiation dose of 36 Gy. For locally advanced nonresectable pancreatic cancer (cStage IVa in JCS), chemoradiotherapy followed by chemotherapy is recommended. Although pancreatic cancer is chemotherapy resistant tumor, systemic chemotherapy is recommended for metastatic pancreatic cancer (cStage IVb in JCS). Single-agent gemcitabine is the standard first line agent for the treatment of advanced pancreatic cancer. Meta-analysis of chemotherapy showed possibility of survival benefit of gemcitabine combination chemotherapy over gemcitabine alone. We hope gemcitabine combination chemotherapy or molecular targeted therapy will improve prognosis of pancreatic cancer in the future. (author)

    Gemcitabine is a key drug for the treatment of pancreatic cancer; however, with its limitation in clinical benefits, the development of another potent therapeutic is necessary. Vascular endothelial growth factor receptor 2 is an essential target for tumor angiogenesis, and we have conducted a phase I clinical trial using gemcitabine and vascular endothelial growth factor receptor 2 peptide (elpamotide). Based on the promising results of this phase I trial, a multicenter, randomized, placebo-controlled, double-blind phase II/III clinical trial has been carried out for pancreatic cancer. The eligibility criteria included locally advanced or metastatic pancreatic cancer. Patients were assigned to either the Active group (elpamotide + gemcitabine) or Placebo group (placebo + gemcitabine) in a 2:1 ratio by the dynamic allocation method. The primary endpoint was overall survival. The Harrington-Fleming test was applied to the statistical analysis in this study to evaluate the time-lagged effect of immunotherapy appropriately. A total of 153 patients (Active group, n = 100; Placebo group, n = 53) were included in the analysis. No statistically significant differences were found between the two groups in the prolongation of overall survival (Harrington-Fleming P-value, 0.918; log-rank P-value, 0.897; hazard ratio, 0.87, 95% confidence interval [CI], 0.486-1.557). Median survival time was 8.36 months (95% CI, 7.46-10.18) for the Active group and 8.54 months (95% CI, 7.33-10.84) for the Placebo group. The toxicity observed in both groups was manageable. Combination therapy of elpamotide with gemcitabine was well tolerated. Despite the lack of benefit in overall survival, subgroup analysis suggested that the patients who experienced severe injection site reaction, such as ulceration and erosion, might have better survival.

    The increased risk of hepatocellular carcinoma (HCC) among patients infected with hepatitis B virus (HBV) is well established; however, long-term risk estimates are needed. Recently, it has been suggested that HBV is associated with non-Hodgkin lymphoma (NHL) and pancreatic cancer (PC). The aim of...... this Danish nationwide cohort study was to evaluate the association between HBV infection and all-type cancer, HCC, NHL and PC. A cohort of patients infected with HBV (n = 4345) and an age- and sex-matched population-based comparison cohort of individuals (n = 26,070) without a positive test for HBV...... were linked to The Danish Cancer Registry to compare the risk of all-type cancer, HCC, NHL and PC among the two groups. The median observation period was 8.0 years. Overall, the incidence rate ratio (IRR) for all-type cancer among HBV-infected patients was 1.1 (95% confidence intervals (CI) 0...

    The incidence of pancreatic ductal adenocarcinoma (PDA) is on the rise, and the prognosis is extremely poor because PDA is highly aggressive and notoriously difficult to treat. Although gemcitabine- or 5-fluorouracil-based chemotherapy is typically offered as a standard of care, most patients do not survive longer than 1 year. Therefore, the development of alternative therapeutic approaches for patients with PDA is imperative. As PDA cells express numerous tumor-associated antigens that are s...

  4. Optimal Second Line Treatment Options for Gemcitabine Refractory Advanced Pancreatic Cancer Patients. Can We Establish Standard of Care with Available Data?

    2008-03-01

    Full Text Available Since the birth of fluorouracil (5-FU 50 years ago, we have made only incremental changes in clinical outcomes in pancreatic cancer. Gemcitabine remains to be the only standard of care in advanced pancreatic cancer since mid-1990s [1]. Numerous trials which enrolled thousands of patients failed to improve the outcome significantly beyond gemcitabine. At present time, data set in 2nd line setting is grossly limited. One reason is that most advanced pancreatic cancer patients who progress on their 1st line treatment are often poor candidates for clinical trials due to their worsening performance status. Lack of active agents seen in number of trials in 1st line is another limitation in advancing agents in 2nd line setting. The change of this rather dark landscape in 1st line setting is suggested by two recent large randomized phase III trials in advanced pancreatic cancer showing that addition of capecitabine or erlotinib to gemcitabine render superiority to single-agent gemcitabine [2, 3].

    Forty-two patients with advanced squamous cell carcinoma of the vulva were treated with a combination regimen of bleomycin 180 mg and external irradiation 30-45 Gy. Twenty patients had primary lesions, and 22 patients had recurrent disease. Fifteen (75%) of the patients with primary disease showed objective response (five complete and ten partial response). Four underwent surgery. Of these, one is alive after 60 months with no evidence of disease. Two have died of unrelated causes without signs of recurrence. Seventeen relapsed and died of carcinoma of the vulva. Median survival for patients treated for primary disease was 8.0 months. Thirteen (59%) of 22 patients treated for recurrence showed objective response (two complete and eleven partial responses). None underwent surgery. All these patients died of carcinoma of the vulva. Median survival was 6.4 months. Toxicity was acceptable, and there were no treatment-related deaths. Even taking into account that our patients had very advanced disease, the results are disappointing. An increase of the radiation dose beyond the maximum of 45 Gy given, and more aggressive surgery, might have improved the results. (orig.).

    Full Text Available Background. Locally advanced carcinoma of maxillary sinus has been historically reported to have poor prognosis. We evaluated the role of NACT in improving the outcome in these patients. Methods. 41 patients with locally advanced technically unresectable (stage IVa or unresectable maxillary carcinoma (stage IVb were treated with induction chemotherapy between 2008 and 2011. The demographic profile, response and toxicity of chemotherapy, definitive treatment received, progression free survival (PFS, and overall survival (OS were analyzed. Univariate and multivariate analysis were performed to determine factors associated with PFS and OS. Results. The chemotherapy included two drugs (platinum and taxane in 34 patients (82.9% and three drugs (platinum, taxane, and 5 FU in 7 (17.1%. There was no complete response seen in any of the patients, stable disease in 18 (43.9%, partial response in 16 (39%, and progression in 7 (17.1% patients. After induction, the treatment planned included surgery in 12 (29.3%, CT-RT in 24 (58.5%, radical RT in 1 (2.4%, palliative RT in 1 (2.4%, and palliative chemotherapy in 3 (7.3% patients. Overall, the median PFS was 10.0 months. The OS at 24 months and 36 months was 41% and 35%, respectively. Conclusion. In unresectable maxillary carcinoma, induction chemotherapy has clinically significant benefit with acceptable toxicity.

  8. Usefulness of C-arm CT during superselective infusion chemotherapy for advanced head and neck carcinoma

    International Nuclear Information System (INIS)

    To evaluate the usefulness of C-arm computed tomography (CT) during superselective intra-arterial infusion chemotherapy for advanced head and neck carcinoma. C-arm CT was performed during superselective intra-arterial infusion chemotherapy for 11 patients with advanced head and neck carcinoma located in the hypopharynx (n = 3), maxillary sinus (n = 3), oropharynx (n = 1), larynx (n = 1), extra-auditory canal (n = 1), tonsil (n = 1) and tongue (n = 1). The usefulness of C-arm CT during superselective catheterisation was evaluated. On arteriography, nine tumours showed tumour stains and two in the oropharynx or tonsil showed no obvious tumour stains. C-arm CT was performed one to four times (mean ± standard deviation, 2.5 ± 0.8) in each patient during a single procedure. C-arm CT clearly showed not only the vascular territory of the selected branch but also the tumour itself in all patients. Intra-arterial infusion chemotherapy was performed through one to three branches (mean, 1.7 ± 0.9) according to C-arm CT findings without any complications. C-arm CT during superselective intra-arterial infusion chemotherapy was useful to determine the arterial supply of head and neck carcinoma. C-arm CT may replace conventional CT during superselective arteriography in this procedure.

    Full Text Available Shailendra KapoorRichmond, VA, USAI read with great interest the recent article by Hameed et al in a recent issue of your journal.1 The article is very interesting. Interestingly, the past few years have seen the emergence of capecitabine as a highly potent first-line chemotherapeutic agent against advanced systemic carcinomas other than colorectal carcinoma. For instance, capecitabine has recently been used successfully as a first-line monotherapeutic agent for HER-2-negative metastatic breast cancer.2 Cotherapy with agents such as sorafenib and paclitaxel for HER-2-negative metastatic breast cancer has also been recently used first-line, and significantly improves progressionfree survival, in addition to being very safe.3,4 Similarly, in patients with advanced gastric carcinoma, capecitabine has been used successfully as first-line therapy in combination with agents such as cisplatin.5 The XELOX regimen comprising capecitabine in conjunction with oxaliplatin is another recent highly effective alternative for gastric carcinoma.6 The modified XELIRI regimen compromising capecitabine and irinotecan is a further option for advanced and unresectable gastric carcinoma.7View original paper by Hameed and colleagues.

    Full Text Available Aim. Chronic diseases are the leading cause of death worldwide. Advanced glycation end products, known as AGEs, are a major risk factor for diabetes onset and maintenance. Methylglyoxal (MG, a highly reactive metabolite of glucose, is a precursor for the generation of endogenous AGEs. Methods. In this current study we incubated in vitro pancreatic islets from adult rats in absence or presence of MG (10 μmol/l with different concentrations of glucose and different metabolic components (acetylcholine, epinephrine, potassium, forskolin, and leucine. Results. Different effects of MG on insulin secretion were evidenced. In basal glucose stimulation (5.6 mM, MG induced a significant (P<0.05 increase of insulin secretion. By contrast, in higher glucose concentrations (8.3 mM and 16.7 mM, MG significantly inhibited insulin secretion (P<0.05. In the presence of potassium, forskolin, and epinephrine, MG enhanced insulin secretion (P<0.05, while when it was incubated with acetylcholine and leucine, MG resulted in a decrease of insulin secretion (P<0.05. Conclusion. We suggest that MG modulates the secretion activity of beta-cell depending on its level of stimulation by other metabolic factors. These results provide insights on a dual acute effect of MG on the pancreatic cells.

    Full Text Available Peter E ClarkVanderbilt University Medical Center, Nashville, Tennessee, USAAbstract: Advanced renal cell carcinoma (RCC remains a challenging, major health problem. Recent advances in understanding the fundamental biology underlying one form of RCC, ie, clear cell (or conventional RCC, have opened the door to a series of targeted agents, such as the tyrosine kinase inhibitors (TKIs, which have become the standard of care in managing advanced clear cell RCC. Among the newest of these agents to receive Food and Drug Administration approval in this disease is pazopanib. This review will summarize what is known about the fundamental biology that underlies clear cell RCC, the data surrounding the previously approved targeted agents for this disease, including not only the TKIs but also the mTOR inhibitors and the vascular endothelial growth factor-specific agent, bevacizumab, and the newest TKI, pazopanib. It will also explore the potential role for pazopanib relative to the other available agents and where it may fit into the armamentarium for treatment of advanced/metastatic RCC.Keywords: pazopanib, targeted therapy, tyrosine kinase inhibitor, clear cell renal cell carcinoma

    Objective: To evaluate the biodistribution and planar gamma camera imaging characteristics of 188Re labeled insulin-like growth factor 1 analogue (188Re-IGF-1A) in tumor-bearing mice. Methods: (1)To label IGF-1A with 188Re directly and to determine the labeling efficiency. (2)To establish nude mice model which bearing human pancreatic carcinoma cell Patu8988. (3)To scan those nude mice at 15 min, 1 h, 4 h, 24 h, 3 d and 5 d after intratumor injection with 188Re-IGF-1A into their tumors. (4)To scan those nude mice at 15 min, 1 h, 2 h, 4 h and 24 h after intratumor injection with 188ReO4- into their tumors. To calculate the tumor to normal tissue ratio (T/NT) and the percentages of injected dose per gram tissue (%ID/g) of different organs. Results: (1)The labeling efficiency of 188Re-IGF-1A was (94.07 ± 0.32)%. (2)The largest uptake of tumors was (42.38 ± 17.82)%ID/g at 4 h after injection of 188Re-IGF-1A. Then the tumor to normal tissue ratios 5ncreased and the largest tumor to muscle ratio was 6531.79 ± 4930.26 at 5 d after injection. (3) 188ReO4- was major distributed in thyroid glands, stomachs, tumors and blood in nude mice after injection at first. Then %ID/g decreased rapidly in tumors. (4) The difference of %ID/g was significant (t=5.877, t=13.287, P188Re-IGF-1A group than in 188ReO4- group. The largest ratio of tumors in the two groups was 74.10 at 24 h after injection. (5) After being injected, 188Re-IGF-1A formed clear images in tumors, 5 d later, nothing but tumors can be seen. Conclusions: 188Re-IGF-1A has good affinity with human pancreatic cancer, and the tumor to muscle ratios in nude mice is high. So 188Re-IGF-1A is expected to be used for targeting therapy of human pancreatic carcinoma. (authors)

  15. The effectiveness of 125I seed interstitial brachytherapy for transplantation tumor of human pancreatic carcinoma in nude mice: an experiment in vivo

    International Nuclear Information System (INIS)

    Objective: To discuss the effectiveness and therapeutic mechanism of 125I interstitial brachytherapy for transplantation tumor of human pancreatic carcinoma in nude mice. Methods: The human pancreatic cell line Sw1990 was subcutaneously injected into the right lower limb partially dorsal area next to the groin of the immunodeficient BABL /c nude mice. The tumor was removed and cut into small pieces after it was formed,then the tumor pieces were inoculated in nude mice. The tumor developed to 8-10 mm in size after six weeks. A total of 16 nude mice with the suitable tumor size were used in this study. The 16 experimental mice were randomly and equally divided into two groups. The mice in study group (n = 8) were implanted with 125I seeds, while the mice in control group (n = 8) were implanted with ghost seeds. After the implantation both the long and short diameter of the tumors as well as the mouse body weight were measured every 4 days. The tumor weight was measured when the mouse was sacrificed. The paraffin-embedded samples were sent for histopathological examination. Apoptotic cells were checked with terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method. Expression of proliferating cell nuclear antigen (PCNA) was detected with immuno-histochemical staining. Results: The tumor grew slowly in the study group, but rapidly in the control group. The tumor weight in the study group and the control group was (2.68 ± 0.70)g and (4.68 ± 1.45)g, respectively, the difference between two groups was statistically significant (P = 0.021). The tumor inhibition rate was about 42.66%. No significant difference in body weight of nude mice existed between two groups both before and after the treatment (P > 0.05). Marked tumor necrosis was seen in study group, but no obvious, or only a little, tumor necrosis could be observed in the control group. The apoptotic index checked with the TUENL method in the study group and control group was (23.2 ± 1.9)% and

    2008-05-01

    Full Text Available Hepatocellular carcinoma (HCC is one of the most common malignancies worldwide, including Japan. Although the development of imaging modalities has made the early diagnosis of HCC possible, surgically resectable cases are relatively uncommon because of hepatic function reserve and/or an advanced stage at presentation. Several modalities, such as transcatheter arterial chemoembolization, percutaneous ethanol injection, microwave coagulation therapy and radiofrequency ablation are reportedly useful in treating patients with non-resectable disease. However, unfortunately, many HCC patients have tumor recurrence. The overall prognosis of patients with HCC is very poor, and treatment of the advanced form is still problematic. In this article, we review the clinical efficacy and toxicity of enteric-coated tegafur/uracil in the treatment of patients with advanced non-resectable HCC.

    In this case series, three consecutive patients with unresectable locally advanced pancreatic cancer (ULAPC) underwent capsule endoscopy (CE) before and after chemoradiotherapy (CRT) to evaluate duodenal and jejunal mucosa, and to examine the relationship between CE findings and dose distribution. CE after CRT showed duodenitis and proximal jejunitis in all three patients. The most inflamed region was the third part of the duodenum, and in dose distribution, this was the closest region to the center of irradiation. This case series shows that CE can safely diagnose acute duodenitis and proximal jejunitis caused by CRT for ULAPC, and that dose distribution is possible to predict the degree of duodenal and jejunal mucosal injuries.

    Full Text Available Extranodal non-Hodgkin’s lymphomas (NHLs represent up to 30-40% of all NHL cases. The gastrointestinal tract is the most commonly involved extranodal site; accounting for about half of such cases [1]. Stomach and the small intestine constitute the most common gastrointestinal sites. Secondary invasion of the pancreas from contiguous, retroperitoneal lymph node disease is the prevalent mode of involvement. Secondary involvement of the pancreas from the duodenum or adjacent peripancreatic lymphadenopathy is well-known. Primary pancreatic lymphoma (PPL is an extremely rare disease [2]. PPL can present as an isolated mass mimicking pancreatic carcinoma. However, unlike carcinomas, PPL are potentially treatable [3].

    Background Locally advanced pancreatic cancer (LAPC) is associated with high mortality, and biomarker-driven treatment approach is currently lacking. This study evaluated safety and efficacy of a combination approach of chemotherapy followed by chemo-radiotherapy (CRT) +/− cetuximab, and the prognostic role of miR-21 in patients with LAPC treated with a multimodality approach. Patients and Methods This was a randomised phase II trial in which patients with inoperable LAPC were offered gemcitabine and capecitabine (GEM-CAP) for 16 weeks. Patients with stable disease or response after GEM-CAP were randomised to capecitabine or UFT plus radiotherapy (RT) (A), or capecitabine or UFT plus cetuximab plus RT (B). The primary outcome of the study was overall survival (OS). Clinical outcome was compared according to baseline circulating miR-21 levels. Results 17 patients were enrolled and treated with GEM-CAP, with 13 patients achieving disease control and being randomised to arms A (n:7) and B (n:6). After a median follow-up of 61.2 months, median progression free survival (PFS) was 10.4 months and 12.7 months, median OS was 15.8 months and 22.0 months in arms A and B respectively (p > 0.05). Patients with high baseline plasma miR-21 had worse PFS (3.5 vs. 12.7 months; p:0.032) and OS (5.1 vs 15.3 months; p:0.5) compared to patients with low miR-21. Circulating miR-21 levels reflected miR-21 expression within the tissues. Conclusions Addition of Cetuximab to CRT following induction chemotherapy did not improve survival. High miR-21 baseline plasma expression was associated with poor clinical outcome in LAPC patients treated with induction chemotherapy followed by chemo-radiotherapy. PMID:26862857

  1. Using economic analysis to evaluate the potential of multimodality therapy for elderly patients with locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose: Development of new and expensive drugs with activity against pancreatic cancer has made economic considerations more relevant to treatment decision-making for advanced disease. Economic modeling can be used to explore the potential of such novel therapies and to inform clinical trial design. Methods and Materials: We developed a Markov model to evaluate the cost-effectiveness of radiation plus fluorouracil (RT-FU) relative to no treatment in elderly patients with locally advanced pancreatic cancer (LAPC) and to determine the economic potential of radiation plus gemcitabine (RT-GEM), a novel regimen for this disease. We used the SEER-Medicare database to estimate effectiveness and costs supplemented by data from the literature where necessary. Results: Relative to no treatment, RT-FU was associated with a cost-effectiveness ratio (ICER) of $68,724/QALY in the base case analysis. Compared with RT-FU, the ICER for RT-GEM was below $100,000/QALY when the risk of dying with the new regimen was 1,000 subjects would be necessary to demonstrate this level of efficacy in a randomized trial. The ICER of RT-GEM was most sensitive to utility values, and, at lower efficacy levels, to costs of gemcitabine and treatment-related toxicity. Conclusions: In elderly patients with LAPC, RT-FU is a cost-effective alternative to no treatment. The novel regimen of RT-GEM is likely to be cost-effective at any clinically meaningful benefit, but quality-of-life issues, drug acquisition, and toxicity-related costs may be relevant, especially at lower efficacy levels

  2. The diagnostic accuracy of magnetic resonance imaging in pancreatic carcinoma based on a retrospective analysis of vascular involvement

    International Nuclear Information System (INIS)

    A retrospective analysis was made to evaluate the diagnostic accuracy of magnetic resonance (MR) imaging for pancreatic cancer. Twenty-one lesions from 21 patients with pancreatic cancer were examined and all except one, were identified on MR images by a disparity in contrast and/or morphological enlargement. The patients were divided into 3 groups, based on the relationship between the tumor and the portal vein, seen on the MR images. These groups were defined as the separate, touching, and surrounding groups. The MR findings correlated with the findings at laparotomy in 16 patients, 10 of whom underwent tumor excision. In the remaining 4, the MR findings correlated with the angiographic findings. The presence or absence of vascular involvement was correctly diagnosed in 18 of the 21 patients. MR imaging proved useful for detecting pancreatic cancer and cancerous infiltration into the portal vein. MR imaging should therefore aid the surgeon in determining the operability and/or curability of patients with pancreatic cancer. (author)

  3. Induction chemotherapy and radiotherapy in loco-regionally advanced epidermoid carcinoma of the anal canal

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy of induction chemotherapy in combination with radiotherapy for treatment of loco-regionally advanced epidermoid anal carcinoma. Methods and Materials: Thirty-one patients diagnosed during the period 1989-1994 with loco-regionally advanced cancer of the anal canal (PHITmax ≥ 4 cm or T4 or N+) were treated with induction chemotherapy consisting of one to three courses of carboplatin (300-375 mg/m2 i.v.) and 5-fluorouracil [5,000 mg/(m2 x 120 h) i.v.] followed by external beam irradiation ± surgery. Results: The toxicity of the chemotherapy was low. Twenty-nine patients were tumor free after the primary therapy. Kaplan-Meier analyses were made for overall survival, tumor-specific survival, freedom from recurrence, preservation of sphincter, and event-free survival. For these end points the 5-year data were 67, 85, 80, 69, and 51%, respectively. Conclusion: The results are promising but a well-designed randomized trial is needed to further elucidate the role of induction chemotherapy in the treatment of loco-regionally advanced anal carcinoma

  4. Risk stratification of patients with advanced squamous cell carcinoma of cervix treated by radiotherapy alone

    International Nuclear Information System (INIS)

    Purpose: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. Methods and Materials: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. Results: In the study group, independent risk factors for local relapse were advanced stage and age 2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level 2, and positive lymph nodes. Conclusion: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses

  5. Prognostic factors in the treatment of locally advanced hepatocellular carcinoma with radiotherapy and arterial infusion

    International Nuclear Information System (INIS)

    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)

    Pancreatic cancer is a malignant neoplasm of the pancreas. A mutation and constitutive activation of K-ras occurs in more than 90% of pancreatic adenocarcinomas. A successful approach for the treatment of pancreatic cancers is urgent. Antroquinonol, a ubiquinone derivative isolated from a camphor tree mushroom, Antrodia camphorata, induced a concentration-dependent inhibition of cell proliferation in pancreatic cancer PANC-1 and AsPC-1 cells. Flow cytometric analysis of DNA content by propidium iodide staining showed that antroquinonol induced G1 arrest of the cell cycle and a subsequent apoptosis. Antroquinonol inhibited Akt phosphorylation at Ser(473), the phosphorylation site critical for Akt kinase activity, and blocked the mammalian target of rapamycin (mTOR) phosphorylation at Ser(2448), a site dependent on mTOR activity. Several signals responsible for mTOR/p70S6K/4E-BP1 signaling cascades have also been examined to validate the pathway. Moreover, antroquinonol induced the down-regulation of several cell cycle regulators and mitochondrial antiapoptotic proteins. In contrast, the expressions of K-ras and its phosphorylation were significantly increased. The coimmunoprecipitation assay showed that the association of K-ras and Bcl-xL was dramatically augmented, which was indicative of apoptotic cell death. Antroquinonol also induced the cross talk between apoptosis, autophagic cell death and accelerated senescence, which was, at least partly, explained by the up-regulation of p21(Waf1/Cip1) and K-ras. In summary, the data suggest that antroquinonol induces anticancer activity in human pancreatic cancers through an inhibitory effect on PI3-kinase/Akt/mTOR pathways that in turn down-regulates cell cycle regulators. The translational inhibition causes G1 arrest of the cell cycle and an ultimate mitochondria-dependent apoptosis. Moreover, autophagic cell death and accelerated senescence also explain antroquinonol-mediated anticancer effect. PMID:21840189

  7. Results of three-dimensional conformal radiotherapy and thalidomide for advanced hepatocellular carcinoma

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the effectiveness of three-dimensional conformal radiotherapy and thalidomide in the treatment of advanced hepatocellular carcinoma. Between 1999 and 2003, 121 patients (mean age, 54.4±12.4 years; range, 20-81 years) with advanced hepatocellular carcinoma received three-dimensional conformal radiotherapy and thalidomide. Radiation was delivered in 1.5 Gy fractions twice daily for 5 days a week, for a total dose of 45-75 Gy. Mean treatment volume was 429.52±408.50 cm3 (range, 26.89-2284.82 cm3). Thalidomide was given concomitantly: 200 mg/day in 109 patients, 300 mg/day in 8 patients and 400 mg/day in 4 patients. Treatment responses, survival rates and factors affecting survival were analyzed. Treatment responses were observed in 61% of the patients. Liver cirrhosis (P=0.001) and tumor size (P=0.001) significantly affected the tumor responses. Overall survival at 6, 12 and 24 months was 84.8, 60.0 and 44.6%, respectively. On univariate analysis, liver cirrhosis (P=0.003), Karnofsky performance status (P=0.007), tumor size (P<0.001), portal vein tumor thrombosis (P<0.001) and alpha-fetoprotein level (P=0.003) were shown to significantly affect survival. On multivariate analysis, only thrombosis (P=0.039) and alpha-fetoprotein level (P=0.006) were shown to be factors affecting survival. Three-dimensional conformal radiotherapy with thalidomide seems to be effective in the treatment of advanced hepatocellular carcinoma. (author)

    To investigate clinical implications of FDG uptake in the thyroid glands in patients with advanced breast carcinoma by comparing metabolic and morphologic patterns on positron emission tomography (PET)/computed tomography (CT). The institutional review board waived the requirement for informed consent. A retrospective analysis was performed in 146 women (mean age 54 years) with advanced breast carcinoma who received systemic treatment. All patients underwent PET-CT before and after treatment. All PET-CT studies were reviewed in consensus by two reviewers. Morphologic changes including volume and mean parenchymal density of the thyroid glands were evaluated. Maximum standardized uptake value (SUVmax) and total lesion glycolysis (TLG) were determined to evaluate metabolic changes. These parameters were compared between patients with chronic thyroiditis who received thyroid hormone replacement therapy and those who did not. Of the 146 patients, 29 (20%) showed bilaterally diffuse uptake in the thyroid glands on the baseline PET-CT scan. The SUVmax showed a linear relationship with volume (r = 0.428, p = 0.021) and the mean parenchymal density (r = -0.385, p = 0.039) of the thyroid glands. In 21 of the 29 patients (72%) with hypothyroidism who received thyroid hormone replacement therapy, the volume, mean parenchymal density, SUVmax, and TLG of the thyroid glands showed no significant changes. In contrast, 8 of the 29 patients (28%) who did not receive thyroid hormone replacement therapy showed marked decreases in SUVmax and TLG. Diffuse thyroid uptake on PET-CT represents active inflammation caused by chronic thyroiditis in patients with advanced breast carcinoma. Diffuse thyroid uptake may also address the concern about subclinical hypothyroidism which develops into overt disease during follow-up. (orig.)

  9. Neoadjuvant chemotherapy and radiation therapy compared with radiation therapy alone in advanced nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Purpose: To analyze the impact of neoadjuvant chemotherapy on the treatment of locoregionally advanced nasopharyngeal carcinoma and to assess the outcomes of patients receiving such treatment. Methods and Materials: We analyzed 137 previously untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with either radiation therapy only or combined radiation therapy and chemotherapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was as follows: AJCC Stage III-21, Stage IV-61 in the radiation therapy group (RT group); AJCC Stage III-1, Stage IV-54 in neoadjuvant chemotherapy and radiation therapy group (CT/RT group). The median follow-up for surviving patients was 48 months. Results: The 5-year overall survival (OS) rates were 71% for the CT/RT group and 59% for the RT group (p = 0.04). The 5-year actuarial disease-free survival (DFS) rates were 63% for the CT/RT group and 52% for the RT group (p = 0.04). Distant metastasis (DM) incidence was significantly lower in the CT/RT group. The 5-year freedom from distant metastasis rates were 84% for the CT/RT group and 66% for the RT group (p 0.01). The incidence of locoregional failures was also lower in the CT/RT group, although this difference did not reach statistical significance (69% vs. 56%, p = 0.09) Conclusion: While not providing conclusive evidence, historical evidence from this institution suggests that neoadjuvant chemotherapy significantly improves both overall and the disease-free survival of patients with advanced stage nasopharyngeal carcinoma

    A 55-year-old male patient with hepatitis B-related liver cirrhosis was found to have advanced hepatocellular carcinoma. His AFP was initially 9828 mg/L and rapidly dropped to 5597 mg/L in ten days after oral sorafenib treatment. However, he developed acute renal failure, hyperkalemia, and hyperuricemia 30 d after receiving the sorafenib treatment. Tumor lysis syndrome was suspected and intensive hemodialysis was performed. Despite intensive hemodialysis and other supportive therapy, he developed multiple organ failure (liver, renal, and respiratory failure) and metabolic acidosis. The patient expired 13 d after admission.

    The prognosis of locally advanced or recurrent squamous cell carcinoma (SCC) of the penis after conventional treatment is dismal. This study aimed to evaluate the therapeutic effects of intraarterial chemotherapy with gemcitabine and cisplatin on local y advanced or recurrent SCC of the penis. Between April 1999 and May 2011, we treated 5 patients with locally advanced penile SCC and 7 patients with recurrent disease with intraarterial chemotherapy. The response rate and toxicity data were analyzed, and survival rates were calculated. After 2 to 6 cycles of intraarterial chemotherapy with gemcitabine and cisplatin, 1 patients with locoregional y advanced disease achieved a complete response, and 4 achieved partial response. Of the 7 patients with recurrent disease, 2 achieved complete response, 3 achieved partial response, 3 had stable disease, and 1 developed progressive disease. An objective tumor response was therefore achieved in 10 of the 12 patients. The median overal survival for the patients was 24 months (range, 10-50 months). Three out of 10 patients who responded were long-term survivors after intraarterial chemotherapy. Intraarterial chemotherapy with gemcitabine and cisplatin may be effective and potential y curative in locoregional y advanced or recurrent penile SCC. The contribution of this therapy in the primary management of advanced or recurrent penile SCC should be prospectively investigated.

  15. Radiation therapy for the treatment of feline advanced cutaneous squamous cell carcinoma

    International Nuclear Information System (INIS)

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T1, and six as T4 according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

  16. FDG PET imaging of locally advanced gastric carcinomas: correlation with endoscopic and histopathological findings

    International Nuclear Information System (INIS)

    Gastric cancer carries a poor prognosis and is the second most frequent cause of cancer-related death worldwide. In spite of the clinical importance of this tumour entity, only a few fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) studies have been published on gastric carcinomas. The aim of this study was to characterise the FDG uptake of gastric carcinomas by relating it to the histopathological properties of the tumours. Within this context, we focussed particularly on the microscopic growth type according to Lauren since our preliminary observations indicated low FDG accumulation in the non-intestinal growth type compared with the intestinal type. Forty patients with locally advanced gastric carcinomas and ten control subjects were studied by FDG PET (300 MBq i.v., emission scan: 40 min p.i., one bed position, measured transmission, filtered back-projection). Detectability of the tumours was qualitatively assessed by two independent observers. For quantitative analysis the regional tumour uptake was measured by standardised uptake values (SUV normalised to the body surface area) using a region of interest technique. Qualitative and quantitative analyses were performed with respect to the microscopic growth type according to Lauren (intestinal type vs non-intestinal type). Other histopathological characteristics were also assessed: mucus content, grading, tumour extension and tumour location. In 36 patients the survival rates were compared for detectable vs non-detectable tumours and for tumour FDG uptake above and below the median. Only 24 of the 40 locally advanced gastric carcinomas (60%) were detected by FDG PET. The detection rate for tumours of the intestinal type was significantly higher than that for tumours of the non-intestinal type (83% vs 41%, P=0.01). Only 2/18 intestinal type tumours contained extracellular or intracellular mucus whereas 17/22 non-intestinal tumours did so (P<0.01). The mean SUV was significantly different

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the surgical management for the pancreatic cancer from the point of view of the curability and function. A total of 570 patients who underwent pancreatectomy for invasive ductal adenocarcinoma of the pancreatic head between 1981 and 2010 were reviewed by decade retrospectively. Patients were divided into three groups; first decade (1981-1990, n=172), middle decade (1991-2000, n=194) and last decade (2001-2010, n=204). Patients with severe invasion to the SMA nerve plexuses were included for surgical indication in the first decade, but were excluded for surgical indication in the middle and last decades. Circle dissection of the SMA nerve plexuses was performed in the first decade, but right-side dominant semicircle dissection was performed in the middle and last decades. Prophylactic dissection of the paraaortic lymph nodes (No.16) was performed in the first and middle decades, but not in the last decade. Stomach preserving procedure was performed in the middle and last decades, but not in the first decade. Intraoperative radiotherapy (IORT) was performed in the first decade and adjuvant chemotherapy was performed in the last decade, but no adjuvant therapy was performed in the middle decade. There was no difference in the prevalence of Stage I/II/III and IVa/IVb between the three groups. Rates of the stomach preserving procedure were 10% in the first decade, 70% in the middle decade and 88% in the last decade. Rates of R0 resection were 47%, 53% and 72%, respectively. Incidence rates of severe diarrhea were 23%, 8%, 5%, and the incidence rates of delayed gastric emptying (DGE) in the patients with stomach-preserving procedure were 29%, 10%, 3%, respectively. Median survival time (MST), 3-year survival rate, 5-year survival rate were 9.4 months, 7.0%, 6.4% in the first decade, 15.4 months, 20.0%, 17.2% in the middle decade and 26.3 months, 40.6%, 33.6% in the last decade. In conclusion, the appropriate surgical indication, R0

  20. Electrochemotherapy as a new therapeutic strategy in advanced Merkel cell carcinoma of head and neck region

    International Nuclear Information System (INIS)

    Merkel Cell Carcinoma (MCC) is a rare and aggressive tumour, arising from a cutaneous mechanoceptor cell located in the basal layer of epidermis, with poor prognosis. The treatment of choice for the initial stage of the disease is surgery and/or radiotherapy. The treatment of recurrent or advanced disease is still controversial. We report a case of 84 years old woman with a recurrent MCC of the chin treated with electrochemotherapy (ECT). During the period of 20 months, four sessions of ECT were employed, which resulted in an objective response of the tumour and good quality of residual life. Our case shows the effectiveness of ECT in the treatment of locally advanced MCC of the head and neck region in a patient not suitable for standard therapeutic options

    Between December 2005 and October 2009, FDA approved six targeted therapies shown to significantly extend survival for advanced renal cell carcinoma (RCC) patients in clinical trials. This study aimed to examine changes in survival between the pretargeted and targeted therapy periods in advanced RCC patients in a real-world setting. Utilizing the 2000-2010 SEER Research files, a pre-post study design with a contemporaneous comparison group was employed to examine differences in survival outcomes for patients diagnosed with advanced RCC (study group) or advanced prostate cancer (comparison group, for whom no significant treatment innovations happened during this period) across the pretargeted therapy era (2000-2005) and the targeted therapy era (2006-2010). RCC patients diagnosed in the targeted therapy era (N = 6439) showed improved survival compared to those diagnosed in the pretargeted therapy era (N = 7231, hazard ratio (HR) for all-cause death: 0.86, P < 0.01), while the change between the pre-post periods was not significant for advanced prostate cancer patients (HR: 0.97, P = 0.08). Advanced RCC patients had significantly larger improvements in overall survival compared to advanced prostate cancer patients (z = 4.31; P < 0.01). More detailed year-to-year analysis revealed greater survival improvements for RCC in the later years of the posttargeted period. Similar results were seen for cause-specific survival. Subgroup analyses by nephrectomy status, age, and gender showed consistent findings. Patients diagnosed with advanced RCC during the targeted therapy era had better survival outcomes than those diagnosed during the pretargeted therapy era. Future studies should examine the real-world survival improvements directly associated with targeted therapies. PMID:26645975

  2. Phase 1 Pharmacogenetic and Pharmacodynamic Study of Sorafenib With Concurrent Radiation Therapy and Gemcitabine in Locally Advanced Unresectable Pancreatic Cancer

    International Nuclear Information System (INIS)

    Purpose: To define the safety, efficacy, and pharmacogenetic and pharmacodynamic effects of sorafenib with gemcitabine-based chemoradiotherapy (CRT) in locally advanced pancreatic cancer. Methods and Materials: Patients received gemcitabine 1000 mg/m2 intravenously weekly × 3 every 4 weeks per cycle for 1 cycle before CRT and continued for up to 4 cycles after CRT. Weekly gemcitabine 600 mg/m2 intravenously was given during concurrent intensity modulated radiation therapy of 50 Gy to gross tumor volume in 25 fractions. Sorafenib was dosed orally 400 mg twice daily until progression, except during CRT when it was escalated from 200 mg to 400 mg daily, and 400 mg twice daily. The maximum tolerated dose cohort was expanded to 15 patients. Correlative studies included dynamic contrast-enhanced MRI and angiogenesis genes polymorphisms (VEGF-A and VEGF-R2 single nucleotide polymorphisms). Results: Twenty-seven patients were enrolled. No dose-limiting toxicity occurred during induction gemcitabine/sorafenib followed by concurrent CRT. The most common grade 3/4 toxicities were fatigue, hematologic, and gastrointestinal. The maximum tolerated dose was sorafenib 400 mg twice daily. The median progression-free survival and overall survival for 25 evaluable patients were 10.6 and 12.6 months, respectively. The median overall survival for patients with VEGF-A -2578 AA, -1498 CC, and -1154 AA versus alternate genotypes was 21.6 versus 14.7 months. Dynamic contrast-enhanced MRI demonstrated higher baseline Ktrans in responding patients. Conclusions: Concurrent sorafenib with CRT had modest clinical activity with increased gastrointestinal toxicity in localized unresectable pancreatic cancer. Select VEGF-A/VEGF-R2 genotypes were associated with favorable survival

    A 58-year-old woman was referred to our hospital with high fever and right upper abdominal pain. Abdominal computed tomography (CT) revealed a bulky tumor of the gallbladder with liver invasion, metastases to para-aortic lymph nodes, and extensive infiltration to Glisson's sheath. The tumor was initially considered to be unresectable locally advanced gallbladder carcinoma with inflammation, and she received 6 courses of chemotherapy with gemcitabine plus cisplatin. Subsequently, the inflammation was extinguished, and CT showed the main tumor shrunk and the Glisson's sheath infiltration disappeared; however, a liver metastasis existed in segment 5. Thus, S4a plus S5 hepatic segmentectomy with extrahepatic bile duct resection and regional and para-aortic lymphadenectomy was performed. The pathological diagnosis was pT3a, pN1, pM1 (Hep, LYM), fStage ⅣB. Curative resection was then performed. If selected according to their response to downsizing chemotherapy, conversion therapy might therefore be an effective multidisciplinary treatment for patients with initially unresectable locally advanced gallbladder carcinoma.

  5. Cryotherapy combined with chemoembolization for the treatment of advanced hepatic carcinoma: a clinical study

    International Nuclear Information System (INIS)

    Objective: To discuss the technique, efficacy and clinical significance of cryoablation combined with transcatheter arterial chemoembolization(TACE) for the treatment of advanced hepatic carcinoma. Methods: One hundred and ninety-two patients, who accorded with the selected criterion, were divided into TACE group (n=100) and combination group (cryotherapy combined with TACE, n=92). Pre-and post-treatment AFP level, recurrence rate and life span between two groups were compared. Results: The complete necrosis rate of the tumor and the recurrence rate in TACE group were 29% and 42%, which were 88.04% and 24% in combination group, respectively. The serum AFP level was significantly decreased after treatment in both groups (P<0.05), and the reduction in AFP level was significantly greater in combination group than that in TACE group (P<0.05). During a follow-up of 30 months the survival rate at each evaluation period of combination group was higher than that of TACE group without exception. Conclusion: As an effective and safe technique, cryoablation combined with chemoembolization is far superior to simple TACE in treating advanced hepatic carcinoma. (authors)

    A therapeutic alternative to exenteration for large locally advanced vulvar carcinoma involving the rectum, anus, or vagina is the use of preoperative radiation followed by radical surgery. Between 1980 and 1988, 13 patients with Stage III and 3 with Stage IV vulvar carcinoma involving the rectum/anus, urethra, or vagina were treated with 4000 rad to the vulva and 4500 rad to the inguinal and pelvic nodes followed by a radical vulvectomy and inguinal lymphadenectomy 4 weeks later. The overall 5 year cumulative survival was 45%. Twelve tumors regressed after radiation with 62.5% of the patients having visceral preservation while in 4 patients there was no major response to radiation and urinary or fecal diversion was required. Of the 6 recurrences 4 were central and 2 distant. Three patients with central recurrences had tumor within 1 cm of the vulvectomy margin. Complications included wet desquamation, inguinal wound separation, lymphedema, and urethral strictures. There were no operative deaths. It is concluded that the use of preoperative radiation followed by radical vulvectomy may be an alternative to pelvic exenteration in selected patients with advanced vulvar lesions.

  7. Hemoglobin as an important prognostic factor in concurrent chemoradiotherapy for locally advanced carcinoma of the cervix

    International Nuclear Information System (INIS)

    The objective of this study was to examine a possible association of hemoglobin with clinical outcome in patients with locally advanced squamous cell carcinoma of the cervix who were treated with concurrent chemoradiotherapy (CCRT). Seventy-five patients with Stage IB to IVA disease who were treated with CCRT were reviewed retrospectively. The mean age was 49.8 years. In the treatment, standard radiotherapy was performed accompanied by concomitant chemotherapy using cisplatin. Pre-treatment hemoglobin was defined as the earliest hemoglobin level prior to the initiation of treatment. Weekly nadir hemoglobin levels throughout treatment were averaged and used as average weekly nadir hemoglobin during treatment (AWNHg). The mean follow-up time was 28.6 months. The mean pre-treatment hemoglobin of 11.6 g/dL was significantly reduced to the mean AWNHg of 9.9 g/dL. The levels of pre-treatment hemoglobin and AWNHg were significantly associated with tumor response to treatment. The 5-year cumulative disease-free survival and overall survival rates for all 75 patients were 67.8% and 75.3%, respectively. Multivariate statistical analysis revealed that AWNHg (≥9.0 versus <9.0 g/dL) was an independent prognostic factor for overall survival (p=0.038), but pre-treatment hemoglobin was not a significant factor. AWNHg was one of the most powerful independent predictors of overall survival in patients undergoing CCRT for locally advanced squamous cell carcinoma of the cervix. (author)

Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449, a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery.

  11. Prospective study of cetuximab and gemcitabine in combination with radiation therapy: feasibility and efficacy in locally advanced pancreatic head cancer

    International Nuclear Information System (INIS)

    Radio-chemotherapy is one of the steps of multidisciplinary management in locally advanced pancreatic cancer. The Epidermal Growth Factor Receptor (EGFR) plays an important role in the disease pathway. The purpose of this prospective study is to evaluate the feasibility and the efficacy of radiotherapy in combination with gemcitabine and EGFR targeting therapy for patients with locally advanced disease. From November 2008 through January 2012, 34 patients were included in this study. In all cases an accurate pre-treatment staging including CT scan, Endoscopic Ultra-Sonography (EUS), 18F - fluorodeoxyglucose (18F-FDG) PET-CT and laparoscopy with peritoneal washing was performed. External beam radiation was delivered with a total dose of 50.4 Gy (1.8 Gy per fraction). Patients were treated using 3D- conformal radiotherapy, and the clinical target volume was the primary tumor and involved lymph nodes. Gemcitabine 300 mg/m2 and Cetuximab were given weekly during radiation therapy. Ten patients (29.4 %) were excluded from the protocol because of the evidence of metastatic disease at the pre-treatment staging. Three patients refused radiochemotherapy. Twenty-one patients completed the therapy protocol. During the combined therapy grade 3–4 toxicities observed were only haematological (leukopenia 47,6 %, trombocytopenia 4.8 %, elevated gamma-GT 23.8 %, elevated alkaline phosphatase 4,8 %). Non-haematological toxicity grade 3–4 was never reported. Post-treatment workup showed partial response in five patients (24 %), stable disease in 11 patients (52 %) and disease progression in 5 patients (24 %). Two-year Local Control was 49 % (median, 18.6 months), 2-year Metastases Free Survival was 24 % (median, 10.8 months). One and two-year Overall Survival were 66 % and 28 % respectively, with a median survival time of 15.3 months. The combination of cetuximab and gemcitabine with concurrent radiation therapy provides a feasible and well tolerated treatment for locally

    Acute pancreatitis is a frequent inflammatory and necrotic process of pancreas and peripancreatic field. To detect the presence of infected or sterile necrotic components and hemorrhage of the pancreatic paranchyma is important for therapeutic approach. Chronic pancreatitis is characterized by irreversible exocrine dysfunction, progressive loss of pancreatic tissue and morphological changes of the pancreatic canal. Imaging modalities play a primary role in the management of both acute and chronic pancreatitis. CT and MR imaging confirm the diagnosis and detect the severity of disease. In chronic pancreatitis, MRCP after Secretin administration, Spiral CT and endoscopic US seems to replace diagnostic ERCP. However differentiation of pseudotumor of chronic pancreatitis from the pancreatic carcinoma is difficult with either imaging modalities.

    Recent advances in understanding of pancreatitis and advances in technology have uncovered the veils of idiopathic pancreatitis to a point where a thorough history and judicious use of diagnostic techniques elucidate the cause in over 80% of cases. This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications, infections, toxins,autoimmune disorders, vascular causes, and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review, areas of controversies are highlighted.

    We investigated the therapeutic effects and safety of fine powder cisplatin for patients with advanced hepatocellular carcinoma( HCC). From January 2006 to March 2012, 123 patients with advanced HCC were treated by transarterial infusion chemotherapy(TAI)with fine-powder cisplatin(IA-call®, Nippon Kayaku Co. Ltd., Tokyo, Japan). The drug was infused into the liver through the feeding artery at a dose of 65 mg/m2. The treatment was repeated every 4 to 8 weeks until evidence of either tumor progression or unacceptable toxicity appeared. Treatment responses were classified as complete response(CR), partial response(PR), stable disease(SD), and progressive disease(PD)in 3.2%, 12.0%, 32.2%, and 52.4% of patients, respectively. The median survival durations were as follows: overall, 12.2 months; CR/PR patients, 23.8 months; and SD/PD patients, 10.6 months. The cumulative survival rates of CR/PR patients were significantly higher than those of SD/PD patients (pPIVKA- II )were predictive factors of survival duration. Problematic adverse events were not observed in any of the patients. Our results suggest that TAI using fine-powder cisplatin can be safely administered for advanced HCC and can improve the prognosis of patients with advanced disease. PMID:24743198

  19. Improvement of cancer cachexia with chemothermotherapy in a patient with advanced pancreatic cancer

    International Nuclear Information System (INIS)

    The ultimate goal of cancer treatment is to achieve a complete eradication of the cancer. However, patients with terminal cancer are also treated to obtain an improvement in their quality of life (QOL). In this report, we describe the dramatic response of an end-stage pancreatic cancer patient with cachexia to a combination of hyperthermia (HT) and chemotherapy (CH). The patient was treated with a combination of intermittent 5-fluorouracil (5-FU)/cisplatin (CDDP) therapy and HT. Three months later, the local recurrent cancer had disappeared, the liver metastases were reduced by 80%, the lung metastatic lesion was markedly reduced, tumor markers had returned to normal, and the cachexia had been almost reversed. Performance status (PS) improved from 4 to 1, QOL improved, and the patient survived until his 258th hospital day. In this patient, the combination of CH and HT was useful not only for improvement of cachexia, but also for tumor reduction. A possible mechanism leading to this effect is discussed. (author)

    Full Text Available Management of pancreatic cancer remains the most challenging work in oncology. Though pancreatic cancer represents only 2-3% of all cancers, it is the most fatal one accounting for the 6% of all cancer death. It remains the 4th cause of death by cancer since 1970s in the U.S.. Gemcitabine remains the only standard of care for this disease. More and more combination therapies containing gemcitabine have been tested or undergoing investigation. The interest in treating pancreatic cancer is apparently global. Over 75 abstracts were presented in the 2009 ASCO Gastrointestinal Cancers Symposium at San Francisco in the field of pancreatic cancer. In this highlights article, authors summarize the critical studies in the management of pancreatic cancer. A large retrospective study evaluated the role of post-operative adjuvant radiation (Abstract #181 and correlated the receipt of radiation with survival benefit. Borderline resectable pancreatic cancer remains an area that requires multi-disciplinary approach. Neo-adjuvant therapy very likely plays a role to downstage to a resectable state in these subgroup patients (Abstracts #197 and #248. In advanced or metastatic setting, studies aiming at the gemcitabine-based triplet or doublet combinations are still the mainstream. FFCD 0301 trial (Abstract #180, the only large phase III trial presented in the first-line setting, failed to demonstrate any survival advantage of either 5-FU and leucovorin plus cisplatin followed by gemcitabine or vice versa. Biologic agents containing regimens were also presented. Of note, gemcitabine and oxaliplatin plus bevacizumab achieved a high response rate of 39% (Abstract #182 while gemcitabine with dual monoclonal antibody regimen was disappointing (Abstract #183. The clear benefit of all other combinations over gemcitabine alone remains questionable given most studies are small. Newer agents, especially S-1 (Abstracts #213 and #251, are very promising, and further studies
