    Proton beam radiation therapy using 250 MeV protons was carried out on two patients with early gastric cancer (T1, N0, M0). One patient was an 85-year-old man with early gastric cancer of type IIa + IIc. The other one was a 70-year-old man with early gastric cancer of type IIc. In both cases histological examination of biopsy specimens showed differential adenocarcinoma; distant metastasis was not found by other examinations. Both patients were considered inoperable due to their poor cardiac and/or respiratory functions. Therefore, it was decided to treat them by definitive proton irradiation, delivering total doses of 86 Gy and 83 Gy, respectively. In both patients, skin erythema that did not require any special treatment was found in the irradiation field. Hematobiological examinations did not show any abnormality. Although endoscopic examination at two years after irradiation in the former case and at seven months in the latter case showed persistent gastric ulcer at the site of the cancerous lesions, cancer cells were not found histologically. Therefore, we concluded that proton irradiation therapy was useful for inoperable early gastric cancers. (author)

    To present the initial experience of percutaneous radiofrequency ablation (RFA) of inoperable primary lung cancer, and to assess the technical feasibility and potential complications. Twenty patients with inoperable lung cancer underwent percutaneous RFA. Nineteen of 20 patients had stage III or IV non-small cell lung cancer, and the remaining one had stage I lung cancer with pulmonary dysfunction. The mean tumor size was 4.6 ± 0.4 cm (range, 1.8-8.4 cm). RFA was performed with a single (n = 18) or cluster (n = 2) cool-tip RF electrode and a generator under CT guidance using local anesthesia and conscious sedation. Twenty tumors were treated in 28 sessions. Patients were assessed by contrast-enhanced CT in all cases at 1 week, 1 month, and 3 months. Eleven patients received chemotherapy (n = 10) or radiotherapy (n = 1) after RFA. RFA was technically successful and well tolerated in all patients. Complete necrosis was attained in 7 lesions (35%), near complete (90-99%) necrosis in 10 lesions (50%), and partial (50-89%) necrosis in 3 lesions (15%). During the mean follow up of 202 days (21 to 481 days), tumor size was decreased in 13 patients, unchanged in 3, and increased in 4. In the latter four, additional RFA was performed. One patient underwent surgery three months after RFA and the histopathologic findings showed a large cavity with thin fibrotic wall suggestive of complete necrosis. During or after the procedure, pneumothorax (n = 10), moderate pain (n = 4), blood tinged sputum (n = 2), and pneumonia (n = 2) were developed. Chest tube drainage was required in only 1 patient due to severe pneumothorax. Other patients were managed conservatively. Seven patients died at 61 to 398 days (mean, 230 days) after RFA. The remaining 13 patients were alive 21 to 481 days (mean, 187 days) after RFA. RFA appears to be a technically feasible and relatively safe procedure for the cytoreductive treatment of inoperable, non-small cell lung cancer and warrants further

  3. Endoscopic Management of Tumor Bleeding from Inoperable Gastric Cancer

    Tumor bleeding is not a rare complication in patients with inoperable gastric cancer. Endoscopy has important roles in the diagnosis and primary treatment of tumor bleeding, similar to its roles in other non-variceal upper gastrointestinal bleeding cases. Although limited studies have been performed, endoscopic therapy has been highly successful in achieving initial hemostasis. One or a combination of endoscopic therapy modalities, such as injection therapy, mechanical therapy, or ablative therapy, can be used for hemostasis in patients with endoscopic stigmata of recent hemorrhage. However, rebleeding after successful hemostasis with endoscopic therapy frequently occurs. Endoscopic therapy may be a treatment option for successfully controlling this rebleeding. Transarterial embolization or palliative surgery should be considered when endoscopic therapy fails. For primary and secondary prevention of tumor bleeding, proton pump inhibitors can be prescribed, although their effectiveness to prevent bleeding remains to be investigated. PMID:25844339

    Purpose: To conduct a cost-effectiveness analysis to determine whether stereotactic body radiation therapy (SBRT) is a cost-effective therapy compared with radiofrequency ablation (RFA) for patients with unresectable colorectal cancer (CRC) liver metastases. Methods and Materials: A cost-effectiveness analysis was conducted using a Markov model and 1-month cycle over a lifetime horizon. Transition probabilities, quality of life utilities, and costs associated with SBRT and RFA were captured in the model on the basis of a comprehensive literature review and Medicare reimbursements in 2014. Strategies were compared using the incremental cost-effectiveness ratio, with effectiveness measured in quality-adjusted life years (QALYs). To account for model uncertainty, 1-way and probabilistic sensitivity analyses were performed. Strategies were evaluated with a willingness-to-pay threshold of $100,000 per QALY gained. Results: In base case analysis, treatment costs for 3 fractions of SBRT and 1 RFA procedure were $13,000 and $4397, respectively. Median survival was assumed the same for both strategies (25 months). The SBRT costs $8202 more than RFA while gaining 0.05 QALYs, resulting in an incremental cost-effectiveness ratio of $164,660 per QALY gained. In 1-way sensitivity analyses, results were most sensitive to variation of median survival from both treatments. Stereotactic body radiation therapy was economically reasonable if better survival was presumed (>1 month gain) or if used for large tumors (>4 cm). Conclusions: If equal survival is assumed, SBRT is not cost-effective compared with RFA for inoperable colorectal liver metastases. However, if better local control leads to small survival gains with SBRT, this strategy becomes cost-effective. Ideally, these results should be confirmed with prospective comparative data.

    Hundred patients with inoperable cancer of the cervix, who had been treated by primary irradiation, were reviewed with regard to biorhythm on the days of radium application. 5-year survival was lower in patients with unfavorable biorhythm; the differences, however, were not significant. It is concluded that the calculation of biorhythm for the day of radiotherapy has little or no influence on the results of therapy. (orig.) [de

    Twenty cases of the pancreas cancer were treated by means of 60 Co γ or Linac x-rays during the period between 1958 and 1977 at the Cancer Institute Hospital and Tokyo Women's Medical College. 11 were irradiated by external radiation and 9 by intraoperative radiation. Pancreas irradiation was indicated for relief of pain and alleviation of jaundice although the effect was symptomatic. 2500 rad of intraoperative radiation was reasonable dose in about 10 x 10 cm radiation field. Radical curative irradiation for pancreas cancer might be rarely indicated. Radiotherapy of pancreas cancer should be considered in conjunction with multimodal treatment in the future. (author)

    Elective nodal irradiation (ENI) might improve overall survival in patients with inoperable esophageal cancer. We conducted a retrospective analysis to assess the long-term survival and toxicity of esophageal cancer patients treated with ENI versus conventional-field irradiation (CFI). All data in the present study were based on our institutional experience from 2000 to 2005 of patients with inoperable esophageal cancer treated with ENI or CFI plus two concurrent cycles of paclitaxel/cisplatin. Based on the inclusion and exclusion criteria, 89 patients were included in the analysis. Of these patients, 51 were treated with ENI, whereas 38 were treated with CFI. For the per-protocol population, the patients in the ENI group significantly improved in terms of their 10-year disease-specific overall survival (43.1% vs 10.5%, P = 0.019), 10-year disease-free survival (36.7% vs 10.2%, P = 0.040) and 10-year local recurrence-free survival (47.2% vs 17.2%, P = 0.018) compared with the CFI group. Aside from radiation esophagitis, the incidence of grade 3 or greater acute toxicities did not differ between the two groups. Multivariate analysis showed that radiation field, tumor length and clinical stage were independent prognostic factors associated with OS. Concurrent chemoradiotherapy with ENI improves both disease-specific overall survival and loco-regional control in patients with inoperable esophageal cancer receiving per-protocol treatment. The regimen has a manageable tolerability profile. © 2017 The Authors. Cancer Science published by John Wiley & Sons Australia, Ltd on behalf of Japanese Cancer Association.

    Full Text Available Although validated predictive factors for breast cancer chemoresistance are scarce, there is emerging evidence that the induction of certain redox-regulating enzymes may contribute to a poor chemotherapy effect. We investigated the possible association between chemoresistance and cellular redox state regulation in patients undergoing neoadjuvant chemotherapy (NACT for breast cancer. In total, 53 women with primarily inoperable or inflammatory breast cancer who were treated with NACT were included in the study. Pre-NACT core needle biopsies and postoperative tumor samples were immunohistochemically stained for nuclear factor erythroid 2-related factor 2 (Nrf2, Kelch-like ECH-associated protein 1 (Keap1, thioredoxin (Trx, and peroxiredoxin I (Prx I. The expression of all studied markers increased during NACT. Higher pre-NACT nuclear Prx I expression predicted smaller size of a resected tumor (p=0.00052; r=−0.550, and higher pre-NACT cytoplasmic Prx I expression predicted a lower amount of evacuated nodal metastasis (p=0.0024; r=−0.472. Pre-NACT nuclear Trx expression and pre-NACT nuclear Keap1 expression had only a minor prognostic significance as separate factors, but when they were combined, low expression for both antibodies before NACT predicted dismal disease-free survival (log-rank p=0.0030. Our results suggest that redox-regulating enzymes may serve as potential prognostic factors in primarily inoperable breast cancer patients.

    Purpose/Objective: To determine the efficacy of high dose rate (HDR) brachytherapy in patients with medically inoperable endometrial cancer clinically confined to the corpus. Materials and Methods: Forty-two patients with endometrial cancer and an intact uterus have been treated since 1989 with HDR brachytherapy. Twenty-six patients with medically inoperable Stage I disease were treated with radiation alone and form the basis of this study. Obesity was assessed using the body mass index (BMI kg/m{sup 2}) scale. Patients with a BMI above 28 were considered obese and those above 35 morbidly obese, per standard anesthesia guidelines. Brachytherapy was delivered in 5 HDR insertions, 1 week apart, without any external beam radiation. The following doses were delivered per insertion: 5.7 Gy to point S, 7.0 Gy to point W, 8.2 Gy to the vaginal surface and 9.2 Gy to point M. Point M represents the conventional point A dose, while points S and W are myometrial points. A single tandem with either ovoids or cylinders was placed, unless the uterine cavity would accommodate 2 tandems. All treatments were outpatient using intravenous fentanyl and midazolam for sedation. Pelvic ultrasound was commonly used at the time of brachytherapy to verify tandem placement. Three year clinical endpoints were calculated using the Kaplan Meier method. Results: The median follow-up for the study cohort was 21 months with follow-up greater than 36 months in 11 patients. Seventeen of the 26 patients were inoperable due to morbid obesity (median weight and BMI; 316 lbs and 55 kg/m{sup 2}, respectively); the other patients had poor cardiopulmonary reserve {+-} obesity. The median age, KPS (Karnofsky Performance Status), weight, ASA (American Society of Anesthesiologists' Physical Class System) and BMI were 63 yrs, 80%, 285 lbs, 3 and 49 kg/m{sup 2}, respectively. Two patients with an ASA of 3 and 4 died from acute cardio-pulmonary events within 30 days of the last insertion, emphasizing the need

    Transrectal sonography is helpful in the classification of parametrial infiltration prior to treatment as well as in the follow-up. In this study, we performed rectal sonography in cases of inoperable cervical cancer to objectify the reduction of the infiltration of the uterine cervix and of the parametrium. Rectosonography was performed in 10 patients with histologically confirmed cancer of the uterine cervix before and after radiation treatment. The patients were treated with brachytherapy and teletherapy with an average radiation dose of 7680 rad. The whole therapy was finished after 6 to 9 weeks. Rectosonography enabled us to objectify the effect of radiation therapy. The length and width of parametrial infiltration could be measured in relation to the pelvis wall. Furthermore, the configuration of the parametrium could be imaged. Therefore, in cervical cancer, rectosonography is a valuable method to check and the documentate the effect of treatment and to diagnose recurrency. (orig.) [de

  19. Life prolongation and 5-year survival by intensive irradiation of inoperable lung cancer

    1982-01-01

    The effect of intensive radiotherapy on 1-5 year survival rates of patients with inoperable lung cancer is investigated. Some 123 cases were treated with 200 kV X-rays (> 3500 cGy tumour dose) and 1046 with cobalt-60 ν-rays (> 5000 cGy tumour dose). All patients had inoperable, histologically confirmed tumours, limited to one side of the thorax. Survival rates for 1 year were 22% and 37% respectively; for 3 years 1% and 5%; and for 5 years 0 and 2.5%. In all highly differentiated tumours the authors obtained a 5-year survival with telecobalt therapy of 6.5%, and for all oat-cell cases, 2.5%. By comparing the total result with their own control group of 'untreated', but prognostically more favourable patients (122 thoracotomized cases without resection) the increase of survival rates achieved by Cobalt-60 therapy is convincing (2.5 times for 1 year, 5 times for 2 years). Nevertheless, the very unfavourable prognosis for more than half of the cases justifies trials with systemic therapy. To date chemotherapy does not appear to influence survival times (except for small-cell tumours). Therefore randomized trials with two half-body irradiations (800 cGy each, 'Toronto method') are recommended. (Auth.)

    Between August 1996 and May 1999, 50 consecutive, previously untreated patients with carcinoma of the esophagus and who were inoperable for various reasons were treated with weekly doses of cisplatin (35 mg/m{sup 2}, maximum 7 cycles) concurrent with either 66 Gy/33 fractions external beam radiotherapy (EBRT) (n=42) or 50 Gy/25 fractions EBRT and two insertions of high-dose-rate intraluminal radiotherapy of 6 Gy each, spaced a week apart (n=8). Eighty-two percent (41/50) of the patients received the stipulated radiotherapy (RT) dose. Seventy-six percent (38/50) received at least 6 cycles of chemotherapy. Neutropenia in the form of WHO grade II-12% (6/50) and grade III-2% (1/50) was observed. Grade III emesis was seen in 8% (4/50). Improvement in the swallowing status was seen in 84% (42/50). Median duration of dysphagia relief was 6 months. The median overall survival was 9 months with 17% estimated to be alive after 4 years. Combined treatment with single agent cisplatin and definitive radiotherapy for inoperable cancer of the esophagus is safe, well tolerated and reasonably efficacious.

    The aim of this study is to investigate the motivation, ability, preferences, and perceived potential facilitating factors/barriers of patients with inoperable metastatic lung cancer towards exercise programmes. This is a cross-sectional study using survey adopting the Theory of Planned Behaviour (TPB) to obtain patients' experience recruited through Odette Cancer Centre, Sunnybrook Health Sciences Complex. Results were expressed in percentages, P value, and Spearman's rho. Sixty patients were recruited from January 2014 to April 2014. Patients generally had a high level across TPB measures, with 63% of them indicating that they have the motivation to exercise. Significant association in relation to motivation was established on attitudes (importance, P = 0.005, rho = 0.326; helpfulness, P = 0.015, rho = 0.348; and easiness, P = 0.001, rho = 0.375) and subjective norm of close members (P = 0.0069, rho = 0.348) and healthcare professionals (P = 0.012, rho = 0.328). Being a non-smoker (P = 0.042, rho = 0.311), having a past exercise history prior to diagnosis (P = 0.000, rho = 0.563), and absence of COPD (P = 0.016, rho = -0.312) were also shown to have a significant association with motivation to exercise. Patients were motivated to participate in an exercise programme despite contrary belief; however, they might have limited ability and preferred light intensity type of exercise such as walking. Their motivation to exercise was driven by different factors when compared to other cancer patient populations. Thus, it is important for healthcare professionals to understand the factors influencing their motivation and increase their awareness (only 26% of patients indicated receiving advice regarding exercise) to better the care towards patients with metastatic lung cancer.

Local control was dependent on the total tumor dose: after one year local control was 63% for patients treated with >65 Gy, the two year local control was 35%. If treated with 2 , the one year local control was 72%; the two year local control was 44%. Local control was also influenced by the performance status, by the localization of the primary tumor in the left upper lobe and in the periphery of the lung. Local control for tumors in the left upper lobe and in the periphery of the lung was about 70% after one year, and about 40% after two years. The one and two years survival results were correlated with the factors influencing local control. The dose factor, the localization factors and the performance influenced local control independently. Tumors localized in the left upper lobe did metastasize less than tumors in the lower lobe, or in a combination of the two. This was not true for the right upper lobe. No correlation between the TNM system, pathology and the prognosis was found

    In a prospective controlled clinical trial, 102 patients with inoperable non-small lung cancer (NSCLC), limited disease, stage II and III were treated with combination chemotherapy, cisplatin 70 mg/m 2 i.v. on day one and etoposide 100 mg/m 2 i.v. on day one, and etoposide 200 mg/m 2 orally on days 2 and 3, or radiotherapy given in 15 fractions of 2.8 Gy with two anterior/posterior fields during a period of three weeks. The patients completed a validated self-administered questionnaire before the start of treatment that assessed their psychosocial well-being, disease-related symptoms, personal functioning, and every day activity. These subjective varibles were evaluated together with treatment modality, WHO performance status, weight loss, and stage of disease, with regard to their value in predicting survival. Univariate survival analyses were undertaken for each individual factor, median survival was calculated according to life-table analyses. A step-wise multiple regression analysis was used to measure the prognostic value of the various factors. In the univariate analysis, general symptons (p=0.0006) psychosocial well-being (p=0.0002) and stage of disease (p=0.007) were the best predictive factors. In the multiple regression analyses the subjective variables, general symptons (p<0.01) and psychosocial well-being (p<0.05) were shown to have the best predictive value for the patients' survival.

    Image cytometry can measure numerous nuclear features which could be considered a surrogate end-point marker of molecular genetic changes in a nucleus. The aim of the study was to analyze image cytometric nuclear features in paired samples of primary tumor and neck metastasis in patients with inoperable carcinoma of the head and neck. Image cytometric analysis of cell suspensions prepared from primary tumor tissue and fine needle aspiration biopsy cell samples of neck metastases from 21 patients treated with concomitant radiochemotherapy was performed. Nuclear features were correlated with clinical characteristics and response to therapy. Manifestation of distant metastases and new primaries was associated (p<0.05) with several chromatin characteristics from primary tumor cells, whereas the origin of index cancer and disease response in the neck was related to those in the cells from metastases. Many nuclear features of primary tumors and metastases correlated with the TNM stage. A specific pattern of correlation between well-established prognostic indicators and nuclear features of samples from primary tumors and those from neck metastases was observed. Image cytometric nuclear features represent a promising candidate marker for recognition of biologically different tumor subgroups

    Full Text Available Abstract Background The main goal when managing patients with inoperable oesophageal cancer is to restore and maintain their oral nutrition. The aim of the present study was to assess the value of endoscopic palliation of dysphagia in patients with oesophageal cancer, who either due to advanced stage of the disease or co-morbidity are not suitable for surgery. Patients and methods All the endoscopic palliative procedures performed over a 5-year period in our unit were retrospectively reviewed. Dilatation and insertion of self-expandable metal stents (SEMS were mainly used for tight circumferential strictures whilst ablation with Nd-YAG laser was used for exophytic lesions. All procedures were performed under sedation. Results Overall 249 palliative procedures were performed in 59 men and 40 women, with a median age of 73 years (range 35 – 93. The median number of sessions per patient was 2 (range 1 – 13 sessions. Palliation involved laser ablation alone in 24%, stent insertion alone in 22% and dilatation alone in 13% of the patients. In 41% of the patients, a combination of the above palliative techniques was applied. A total of 45 SEMS were inserted. One third of the patients did not receive any other palliative treatment, whilst the rest received chemotherapy, radiotherapy or chemoradiotherapy. Swallowing was maintained in all patients up to death. Four oesophageal perforations were encountered; two were fatal whilst the other two were successfully treated with covered stent insertion and conservative treatment. The median survival from diagnosis was 10.5 months (range 0.5–83 months and the median survival from 1st palliation was 5 months (range 0.5–68.5 months. Conclusion Endoscopic interventions are effective and relatively safe palliative modalities for patients with oesophageal cancer. It is possible to adequately palliate almost all cases of malignant dysphagia. This is achieved by expertise in combination treatment.

    Purpose: To review our experience treating clinical Stage I non-small-cell lung carcinoma with radiotherapy alone using modern techniques and staging. The effect of dose and volume on outcome is to be analyzed. Methods: Between January 1980 and December 1995, 156 patients with Stage I medically inoperable non-small-cell lung cancer were irradiated at Duke University Medical Center and the Durham Veterans Administration Medical Center. Fifteen patients were excluded from analysis (7 treated with palliative intent, and 8 lost to follow-up immediately following radiation). Characteristics of the 141 evaluable patients were as follows: Median age 70 years (range 46-95); gender: male 83%, female 17%; institution: DUMC 65%, DVAMC 35%; T1N0 54%, T2N0 46%; median size 3 cm (range 0.5 to 8); pathology: squamous cell carcinoma 52%, adenocarcinoma 18%, large cell carcinoma 19%, not otherwise specified 11%; presenting symptoms: weight loss 26%, cough 23%, none (incidental diagnosis) 57%. All patients underwent simulation prior to radiotherapy using linear accelerators of ≥4 MV. No patients received surgery or chemotherapy as part of their initial treatment. The median dose of radiotherapy (not reflecting lung inhomogeneity corrections) was 64 Gy (50 to 80 Gy) given in 1.2 bid to 3 Gy qid fractionation. The majority of cases included some prophylactic nodal regions (73%). Results: Of the 141 patients, 108 have died; 33% of intercurrent death, 35% of cancer, and 7% of unknown causes. At last follow-up, 33 patients were alive (median 24 months, range 7-132 months). The 2- and 5-year overall survival was 39% and 13%, respectively (median 18 months). The corresponding cause-specific survival was 60%, and 32% (median 30 months). On multivariate analysis, significant factors influencing overall and/or cause-specific survival were age, squamous cell histology, incidental diagnosis, and pack-years of smoking. There was a nonsignificant trend towards improved cause-specific survival

    Full Text Available Loco-regional therapy, which uses imaging technologies to facilitate targeted delivery of therapeutic agents to cancers, has emerged as the most commonly used non-surgical treatment for primary liver cancer. Since the theory of loco-regional therapy was introduced, various strategies have been developed and successfully applied in clinic, including interventional radiology methods (mainly transarterial chemoembolization and local ablative methods (such as intratumoral ethanol injection, radiofrequency ablation, microwave coagulation, laser-induced thermal therapy, high-intensity focused ultrasound, and cryotherapy. TACE has been widely applied to treat inoperable liver cancers at intermediate and advanced stages, while the local ablative therapies have proven more suitable for small (<5 cm liver cancers. However, choosing the appropriate loco-regional therapy strategy should be carried out on an individual basis, considering the patient's particular disease condition and characteristics. To help guide such treatment decisions, this review highlights the principal indications, theory, techniques, and reported efficacies of the various loco-regional therapy strategies.

    Background Lung cancer is one of the most commonly diagnosed cancers, and is a leading cause of cancer mortality world-wide. Due to lack of early specific symptoms, the majority of patients present with advanced, inoperable disease and five-year relative survival across all stages of non-small cell lung cancer (NSCLC) is 14%. People with lung cancer also report higher levels of symptom distress than those with other forms of cancer. Several benefits for survival and patient reported outcomes ...

    Recent advances in cancer diagnosis and treatment have not yet improved the survival rate of patients with cancers of the brain, liver, etc. In these organs, an extirpation of the organ, which can be done for stomach, breast, cervix, lung, etc. is not allowed, and this fact is the cause of poor therapeutic results. Boron-neutron capture therapy (BNCT) utilizes the nuclear reaction which will take place between the boron-10 (loaded in the cancer cells artificially) and the thermal neutrons (delivered by reactors). The secondary radiations, helium and lithium hit the cancer cell itself and cause the death of the cancer cell while sparing the surrounding normal cells. BNCT is now being tried also by Oda of Kyoto University (9 cases) and by Nakagawa of Tokushima University (7 cases). It has been tried by Mishima (Kobe University) on 12 skin melanoma patients, proving satisfactory local control of the melanomas. Mercaptoundecahydrododecaborate (BHS) and boronophenylalanine (BPA) have been tried for brain tumors and for melanoma. For cancers of the liver and abdominal viscerae, antibody to the tumor specific antigen has been considered a good carrier of boron-10. Surgeons Takahashi, Fujii, Fujii, Yanagie, and Sekiguchi and immunologist Nariuchi of Tokyo University have been involved in the research and have obtained encouraging results in animals. Hatanaka has been proving good effect of BNCT upon giant cerebral arteriovenous malformation (AVM) and skull base meningioma. These diseases, although pathologically benign, have posed difficult problems in neurosurgery. It will be exciting good news to the patients. In conclusion, BNCT appears to be a good means to treat difficult lesions in the brain and other organs which defy sophisticated modern therapeutic means. (author)

    Chronic systemic inflammatory response is proposed as an underlying mechanism for development of cancer cachexia. We conducted a prospective study to examine changes in inflammatory biomarkers during the disease course and the relationship between inflammatory biomarkers and cachexia in patients with inoperable pancreatic cancer. Twenty patients, median (range) age 67.5 (35-79) years, 5 females, were followed for median 5.5 (1-12) months. Cachexia was diagnosed according to the 2011 consensus-based classification system (weight loss >5 % past six months, BMI 2 %, or sarcopenia) and the modified Glasgow Prognostic score (mGPS) that combines CRP and albumin levels. Inflammatory biomarkers were measured by enzyme immunoassays. The patients had increased levels of most inflammatory biomarkers, albeit not all statistically significant, both at study entry and close to death, indicating ongoing inflammation. According to the consensus-based classification system, eleven (55 %) patients were classified as cachectic upon inclusion. They did not differ from non-cachectic patients with regard to inflammatory biomarkers or energy intake. According to the mGPS, seven (35 %) were defined as cachectic and had a higher IL-6 (p cachexia.

    Background and purpose: To report patterns of failure of stereotactic body radiation therapy (SBRT) in inoperable patients with histologically confirmed stage I NSCLC. Materials and methods: Ninety-two inoperable patients (median age: 75 years) with clinically staged, histologically proven T1 (n = 31) or T2 (n = 61), N0, M0 non-small cell lung cancer (NSCLC) were included in this study. Treatment consisted of 3–5 fractions with 7–15 Gy per fraction prescribed to the 60% isodose. Results: Freedom from local recurrence at 1, 3 and 5 years was 89%, 83% and 83%, respectively. All 10 local failures were observed in patients with T2 tumors. Isolated regional recurrence was observed in 7.6%. The crude rate of distant progression was 20.7%. Overall survival at 1, 3, and 5 years was 79%, 38% and 17% with a median survival of 29 months. Disease specific survival at 1, 3, and 5 years was 93%, 64% and 48%. Karnofsky performance status, T stage, gross tumor volume and tumor location had no significant impact on overall and disease specific survival. SBRT was generally well tolerated and all patients completed therapy as planned. Conclusion: SBRT for stage I lung cancer is very well tolerated in this patient cohort with significant cardiopulmonal comorbidity and results in excellent local control rates, although a considerable portion develops regional and distant metastases.

    2009-01-01

    Purpose: Concomitant chemoradiotherapy (CRT) increases survival rates compared with radical radiotherapy alone (RT) in Stage III non-small-cell lung cancer (NSCLC), as a result of improved local control. The effect of CRT on local control in Stage I NSCLC is less well documented. We retrospectively reviewed local control and survival following CRT or RT for inoperable Stage I NSCLC patients. Methods and materials: Eligible patients had histologically/cytologically proved inoperable Stage I NSCLC and had undergone complete staging investigations including an F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scan. Radiotherapy was planned as (1) 60 Gy in 30 fractions over 6 weeks with or without concomitant chemotherapy or (2) 50-55 Gy in 20 fractions without chemotherapy. Results: Between 2000 and 2005, 73 patients met the eligibility criteria and were treated as follows: CRT (60 Gy)-39; RT (60 Gy)-23; RT (50-55 Gy)-11. The median follow-up time for all patients was 18 months (range, 1-81 months). Survival analysis was based on intent to treat. Local progression-free survival (PFS) at 2 years was 66% with CRT and 55% with RT. The 2-year distant PFS was 60% following CRT and 63% after RT. The 2-year PFS rates were 57% and 50%, respectively. The 2-year survival rate for patients treated with CRT was 57% and 33% in patients receiving RT. Conclusions: Despite the use of CRT and routine staging with FDG-PET, both local and distant recurrences remain important causes of treatment failure in patients with inoperable stage I NSCLC.

    Objective: To evaluate the therapeutic efficacy and treatment-related toxicity of stereotactic body radiation therapy (SBRT) in patients with medically inoperable stage I/II non-small cell lung cancer (NSCLC). Methods: SBRT was applied to 30 patients, including clinically staged T 1 , T 2 (≤5 cm) or T 3 (chest wall primary tumors only), N 0 , M 0 ,biopsy-confirmed NSCLC. All patients were precluded from lobotomy because of physical condition or comorbidity. No patients developed tumors of any T-stage in the proximal zone. SBRT was performed with the total dose of 50 Gy to 70 Gy in 10 - 11 fractions during 12 - 15 days. prescription line was set onthe edge of the PTV. Results: The follow-up rate was 100%. The number of patients who completed the 1-, and 2-year follow-up were 15, and 10, respectively. All 30 patients completed therapy as planned. The complete response (CR), partial response (PR) and stable disease (SD) rates were 37%, 53% and 3%, respectively. With a median follow-up of 16 months (range, 4-36 months), Kaplan-Meier local control at 2 years was 94%. The 2-year overall survival was 84% and the 2-year cancer specific survival was 90%. Seven patients(23%) developed Grade 2 pneumonitis, no grade > 2 acute or late lung toxicity was observed. No one developed chest wall pain. Conclusions: It is feasible to deliver 50 Gy to 70 Gy of SBRT in 10 - 11 fractions for medically inoperable patients with stage I / II NSCLC. It was associated with low incidence of toxicities and provided sustained local tumor control.The preliminary investigation indicated the cancer specific survival probability of SBRT was high. It is necessary to perform similar investigation in a larger number of patients with long-term follow-up. (authors)

    Objective: To retrospectively analyze treatment results of radiotherapy for medically inoperable stage I/II non-small cell lung cancer. Methods: Between Jan. 2000 and Dec. 2005, fifty-eight such patients were enrolled into the database analysis, including 37 with clinical stage I and 21 with stage II disease. Fifty patients received radiotherapy alone and eight with radiotherapy and chemotherapy. Forty- three patients were treated with 3-D conformal radiotherapy (3D-CRT) and 15 with conventional radiotherapy. Results: The 1-, 2- and 3-year overall survival rates were 85%, 54% and 30%, and the median survival time was 26.2 months for the whole group. The corresponding figures were 88%, 60%, 36% and 30.8 months for cancer-specific survival; 84%, 64%, 31% and 30.8 months for Stage I disease; 81%, 47%, 28% and 18.8 months for Stage II disease; 95%, 57%, 33% and 30.8 months for 3D-CRT group and 53%, 44%, 24% and 15.3 months for conventional radiotherapy group. By logrank test, tumor volume, pneumonitis of Grade II or higher and weight loss more than 5% showed statistically significant impact on overall survival. Tumor volume was the only independent prognostic factor in Cox multivariable regression. Pneumonitis and esophagitis of Grade II or higher were 16% and 2%, respectively. Age and lung function before treatment had a significant relationship with pneumonitis. Failure included the local recurrence (33%) and distant metastasis (21%). There was no difference between the treatment modalities and failure sites. Conclusions: For medically inoperable early stage non-small cell lung cancer patients, tumor volume is the most important prognostic factor for overall survival. The conformal radiotherapy marginally improves the survival. The age and pulmonary function are related to the incidence of treatment induced pneumonitis. (authors)

    The purpose of this study was to determine the impact of overall treatment time on long-term survival after high-dose radiation therapy alone for inoperable non-small cell lung cancer (NSCLC). Between 1978 and 1990, 229 patients with stage I-III disease and Karnofsky Performance Scores of 80-100 received a conventionally fractionated total dose of 70 Gy through a split-course technique. After a first treatment course of 40 or 50 Gy, a rest aging was performed and only patients without any contraindications, such as newly diagnosed distant metastases or serious deterioration of performance status, were given a second course. In 83% of patients this break lasted for 4-6 weeks. Overall treatment time ranged between 7 and 24 weeks (median 12 weeks). Median follow-up time was 6.6 years (range 4.0-9.3 years). Actuarial overall survival rates at 2 and 5 years were 28% and 7% respectively. Complete radiological tumor response was observed in 31% of patients, and was found to be the strongest positive predictor of survival with 2- and 5-year rates of 50% and 12% respectively compared with 17% and 4% for patients without complete response. Treatment duration was not found to be a significant prognostic factor in univariate or multivariate analysis. For overall treatment times of 7-11 weeks (n=50), 12 weeks (n=79) and >12 weeks (n=100), 5-year survival was 4%, 6%, and 8%, respectively (p=0.6). To conclude, in our experience and in contrast to other studies, prolonged overall treatment times in radiation therapy alone for inoperable NSCLC had no negative impact on long-term survival. It is hypothesized that accelerated tumor cell repopulation is absent in a significant number of these patients with the time-factor playing no apparent role for outcome of treatment. (orig.)

    Considering the various comorbidities associated with aging, the feasibility and usefulness of concurrent chemoradiotherapy (CRT) in older patients with inoperable non-small cell lung cancer (NSCLC) is a controversial issue. Here, we compared the feasibility of CRT and the effects of various comorbidities on the prognosis of a minimally selected population of inoperable NSCLC patients aged 60-77 years. The study comprised 161 patients with inoperable NSCLC who received CRT with a target radiation dose greater than 60 Gy and platinum-based chemotherapy from 1998 to 2007. The total population included 69 patients aged 60-69 years and 53 aged 70-77 years. These two age cohorts were included in the study with a follow-up of a median 14.5 months. The two groups showed no differences in long-term survival, as reflected by the 5-year survival rates of 13.0 ± 4.1 % (60- to 69-year-olds) and 14.4 ± 4.9 % (70- to 77-year-olds). During the treatment phase, the groups were comparable in terms of toxicity and the feasibility of chemotherapy. Compared to patients in their 60s, the septuagenarians had more pulmonary comorbidities (p = 0.02), diabetes mellitus (p = 0.04), cardiac comorbidities (p = 0.08), and previous cancer disease (p = 0.08) that exerted a negative effect on survival. In patients without comorbidities, there were no differences between the age groups. Age is not a contraindication for concurrent CRT per se, because elderly patients do not have a worse long-term prognosis than younger seniors. However, ''elderly patients'' (≥ 70-77 years) have more concomitant diseases associated with shorter survival than ''moderately aged patients'' (≥ 60-69 years). (orig.)

    Purpose: The radiation therapy results for patients with inoperable non-small-cell lung cancer (NSCLC) have been disappointing. Tumor dose escalation using concomitant boost technique (CBT) has been shown to improve local control in a few prospective studies. This trial was carried out to prospectively assess the radiation response and acute toxicity of CBT in comparison to the conventional treatment technique (CTT). Methods and Materials: Ninety-seven consecutive eligible patients were entered in this prospective clinical trial between November 1994 and February 1998. Patients were randomized to receive either CBT (43 patients) or CTT (54 patients) radiation therapy. These patients either refused chemotherapy or were judged as unsuitable for chemotherapy. Patients in the CBT group received 46.8 Gy in 26 fractions using large fields that encompassed the gross and occult disease. A concomitant boost of 18.2 Gy (0.7 Gy per fraction) was delivered to the gross disease using small fields with 1.5-cm margins. The small fields were treated concurrently with the large fields and the total dose to the tumor area was 65 Gy in 26 fractions. Patients in the CTT group received 70.8 Gy in 38 fractions. The acute toxicity between each group was compared. The response rate was analyzed and compared by treatment group, gender, age, stage, histology, initial Karnofsky performance score (KPS), severity of acute toxicity, and maximum body weight loss (MBWL) during treatment course. Results: The demographic parameters such as sex, age, and stage were evenly distributed in each treatment group. The majority of these patients had Stage IIIA and IIIB disease. Overall median treatment times were 39 days for the CBT group of patients and 62 days for the CTT group. No treatment-related mortality was found. There were 2 patients in the CTT group with acute RTOG Grade 3 lung toxicity, and no Grade 3 lung or esophageal toxicity was observed in CBT group. The response rates, assessed by

    Purpose: To evaluate the role of definitive radiation therapy (RT) in the treatment for medically inoperable patients with stage I-II non-small cell lung cancer (NSCLC). Materials and Methods: From 1976 through 1989, 84 patients with clinical stage I and II NSCLC were treated with definitive RT alone at Gunma University hospital. All patients were treated with 10 MV X-rays using antero-posterior parallel opposed fields. The total dose ranged from 60 Gy to 90 Gy (35 pts; 60-69 Gy, 39 pts; 70-74 Gy, 10 pts; ≥ 80 Gy) with once-daily standard fractionation. Results: The two and five-year survival rates were 74% and 31% for 28 patients with stage I disease, as compared with 40% and 19% for 56 patients with stage II respectively (p<0.05). Although there was no significant difference of survival rates by the histologic subtypes, in the patients with squamous cell carcinoma there were more long-term survivors. Fifty-three patients with tumors less than 5 cm in diameter had an infield progression rate of 14% at two years, in comparison with 38% of 31 patients with tumors greater than 5 cm (p<0.05). Overall distant failure occurred in 57% of the patients with smaller tumors and in 80% of the patients with larger tumors (p<0.05). The difference of survival rates for these two groups was statistically significant (p<0.005). Ten patients given a total dose of 80Gy or over had only 17% local progression at the time of last follow-up, however they had not been alive beyond three years because they developed pulmonary insufficiency due to severe stenosis of the proximal bronchus. For age and sex, there were no significant differences in survival, however, patients with performance status of 0-1 lived longer than those with a status of 2 or more (MST 24 versus 13 months; p=0.06). Conclusion: The tumor size was the most important factor not only for local control but also for distant failure. It was also suggested that the optimal radiation dose for medically inoperable stage I

    To induce fast relief of dysphagia in inoperable oesephageal cancer, we applied high-dose rate (HDR) intraluminal irradiation followed by external irradiation (EBRT) in a phase II study. 15 patients (group A: n = 15; 10 men, 5 women; median age 66 years) were treated with 10 Gy HDR brachytherapy plus 40 Gy EBRT (15 fractions of 2.67 Gy). Severe side-effects were encountered in 60% of patients: 3 late ulceration, 2 pending fistula and 2 patients with fatal haemorrhage after an interval of 6 months. Overall response was excellent: 9 complete remissions (60%) and 6 partial responses (40%). Because of the high toxicity rate, in a subsequent study (group B: n = 30; 23 mean, 7 women; median age 66 years) the EBRT scheme was changed using smaller fractions (2.0 Gy) to reach the same total dose of 40 Gy. The complication rate (17%) was significantly reduced, while the overall response remained excellent (83%): 17 complete and 8 partial responses. The impressive change in complication rate of HDR brachytherapy and EBRT stresses the impact of the fraction per dose and illustrates the small therapeutic margins. (author)

    Objective: To evaluate the outcome of radiotherapy for locally advanced pancreatic cancer. Methods: From January 2000 to December 2007, 41 patients with inoperable locally advanced (stage III) pancreatic cancer were treated with three-dimensional conformal radiation therapy(3DCRT) or intensity-modulated radiation therapy (IMRT). Among these patients, 30 received concurrent radio-chemo-therapy. Results: The median survival time(MST) and 1-year overall survival were 9.2 months and 23%. Patients with pretreatment KPS ≥ 80, no regional lymph nodes metastasis, and CR/PR after radiotherapy had better prognosis. The corresponding MSTs were 11.1 months vs 5.8 months (χ 2 =7.50, P=0.006), 10.8 months vs 6.5 months(χ 2 =5.67, P=0.017), and 19.5 months vs 9.1 months (χ 2 =7.28, P=0.007), respectively. Concurrent radio-chemotherapy tended to improve the overall survival(χ 2 =3.25, P=0.072). After radiotherapy, 18 patients had clinical benefit response, mainly being abdominal pain relief. Neither grade 4 hematologic nor grade 3 non-hematologic toxicities were observed. Conclusions: For patients with locally advanced pancreatic cancer, both 3DCRT and IMRT are effective in alleviation of disease-related symptoms. Patients with better performance status before treatment, no regional lymph nodes metastasis, and better response to radiotherapy may have better prognosis. Concurrent radio-chemotherapy trend to improve overall survival when compared with radiotherapy alone. (authors)

    Purpose: To evaluate in a retrospective review the role of proton beam therapy for patients with medically inoperable Stage I non-small-cell lung cancer (NSCLC). Patients and Methods: From November 2001 to July 2008, 55 medically inoperable patients with Stage I NSCLC were treated with proton beam therapy. A total of 58 (T1/T2, 30/28) tumors were treated. The median age of study participants was 77 years (range, 52-86 years). A total dose of 66 GyE in 10 fractions was given to peripherally located tumors and 72.6 GyE in 22 fractions to centrally located tumors. Results: The rates (95% confidence interval) of overall and progression-free survival of all patients and of local control of all tumors at 2 years were 97.8% (93.6-102.0%), 88.7% (77.9-99.5%), and 97.0% (91.1-102.8%), respectively. There was no statistically significant difference in progression-free rate between T1 and T2 tumors (p = 0.87). Two patients (3.6%) had deterioration in pulmonary function, and 2 patients (3.6%) had Grade 3 pneumonitis. Conclusion: Proton beam therapy was effective and well tolerated in medically inoperable patients with Stage I NSCLC.

  15. FIRST-LINE TREATMENT IN PATIENTS WITH INOPERABLE METASTATIC COLON CANCER

    Full Text Available First-line therapy for metastatic colon cancer is most important for a patient. Its median time to progression constitutes the bulk of the patient’s survival. Clearly, it is necessary to choose the most effective combinations of targeted drugs and chemotherapy regimens. The choice of therapy for patients with colon cancer is governed by both the clinical characteristics of the disease and the molecular changes of a tumor. In recent literature, there has been a great deal of evidence for the use of targeted drugs in different clinical situations; the results of comparative trials of different treatment combinations have been published. This all determines the reconsideration of the choice of a treatment regimen in patients with metastatic colon cancer; it is the topic of the present review.

    Aim:Trans-arterial Radio-conjugate therapy plays an important role in the palliative treatment of inoperable liver cancer. It also helps in reduction of the tumor to an operable state from an inoperable one. As a part of an IAEA sponsored coordinated research project, a new radiopharmaceutical, Rhenium-188 Lipiodol has been developed. The aim of this study was to establish the safety of the radiopharmaceutical and to find out the efficacy of treatment. Materials and Methods: Eight patients suffering from various forms of liver cancer (Hepatocellular carcinoma-4, Metastases from carcinoma of colon-3 and Carcinoid- 1) were treated with Rhenium -188 Lipiodol. Seven out of the eight patients were classified as ECOG- 1 and one as ECOG- 3. Labelling of Rhenium-188 with Lipiodol was carried out according to a protocol developed under the CRP and standardized in our service. Rhenium-188 Lipiodol was administered through the trans-arterial route by either selective (75%) or ultra selective (25%) hepatic arteriography. Administered therapeutic doses ranged between 170 MBq and 4181 MBq. Dosimetric evaluations were made using the IAEA developed dosimetry spreadsheet. All patients were followed up (1-5 months, average = 2 months) after treatment by clinical examination, liver function tests, haematological examinations and CT scans of liver to determine the size of hepatic tumor. Results: Rhenium-188 Lipiodol treatment was well tolerated by all patients. No immediate systemic complications were noted in any of the patients within 72 hrs. following therapy. Only two patients had mild rise in temperature in the immediate post-therapy period, which subsided subsequently. One patient who was classified as Child B and ECOG 3, developed encephalopathy on the seventh day after treatment. He died of hepatic failure. Another one present depressive syndrome, didn't accept food and died Follow-up CT scans in all the surviving (6/8) patients revealed significant reduction of the tumours

    This randomised phase III study was conducted to investigate the efficacy of extended nodal irradiation (ENI) and/or erlotinib in inoperable oesophageal squamous cell cancer (ESCC). Patients with histologically confirmed locally advanced ESCC or medically inoperable disease were randomly assigned (ratio 1:1:1:1) to one of four treatment groups: group A, radiotherapy adoption of ENI with two cycles of concurrent TP chemotherapy (paclitaxel 135 mg/m 2  day 1 and cisplatin 20 mg/m 2 days 1-3, every 4 weeks) plus erlotinib (150 mg per day during chemoradiotherapy); group B, radiotherapy adoption of ENI with two cycles of concurrent TP; group C, radiotherapy adoption of conventional field irradiation (CFI) with two cycles of concurrent TP plus erlotinib; group D, radiotherapy adoption of CFI with two cycles of concurrent TP. A total of 352 patients (88 assigned to each treatment group) were enrolled. The 2-year overall survival rates of group A, B, C and D were 57.8%, 49.9%, 44.9% and 38.7%, respectively (P = 0.015). Group A significantly improved 2-year overall survival compared with group D. The ENI significantly improved overall survival in patients with inoperable ESCC (P = 0.014). The addition of erlotinib significantly decreased loco-regional recurrence (P = 0.042). Aside from rash and radiation oesophagitis, the incidence of grade 3 or greater toxicities did not differ among 4 groups. Chemoradiotherapy with ENI and erlotinib might represent a substantial improvement on the standard of care for inoperable ESCC. ENI alone should be adopted in concurrent chemoradiotherapy for ESCC patients. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Lung cancer is one of the most commonly diagnosed cancers, and is a leading cause of cancer mortality world-wide. Due to lack of early specific symptoms, the majority of patients present with advanced, inoperable disease and five-year relative survival across all stages of non-small cell lung cancer (NSCLC) is 14%. People with lung cancer also report higher levels of symptom distress than those with other forms of cancer. Several benefits for survival and patient reported outcomes are reported from physical activity and exercise in other tumour groups. We report the protocol for a study investigating the benefits of exercise, behaviour change and symptom self-management for patients with recently diagnosed, inoperable, NSCLC. This multi-site, parallel-group, assessor-blinded randomised controlled trial, powered for superiority, aims to assess functional and patient-reported outcomes of a multi-disciplinary, home-based exercise and supportive care program for people commencing treatment. Ninety-two participants are being recruited from three tertiary-care hospitals in Melbourne, Australia. Following baseline testing, participants are randomised using concealed allocation, to receive either: a) 8 weeks of home-based exercise (comprising an individualised endurance and resistance exercise program and behaviour change coaching) and nurse-delivered symptom self-management intervention or b) usual care. The primary outcome is the between-group difference in the change in functional exercise capacity (six-minute walk distance) from baseline to post-program assessment. Secondary outcomes include: objective and self-reported physical activity levels, physical activity self-efficacy, behavioural regulation of motivation to exercise and resilience, muscle strength (quadriceps and grip), health-related quality of life, anxiety and depression and symptom interference. There is a lack of evidence regarding the benefit of exercise intervention for people with NSCLC, particularly

    High-intensity focused ultrasound (HIFU) in combination with palliative standard therapy is an innovative and effective treatment option for pain reduction in patients with inoperable pancreatic cancer. Evaluation of the effects of additive ultrasound (US)-guided HIFU treatment in inoperable pancreatic cancer on the sensory and affective pain perception using validated questionnaries. In this study 20 patients with locally advanced inoperable pancreatic cancer and tumor-related pain were treated by US-guided HIFU (6 stage III, 12 stage IV according to UICC and 2 with local recurrence after surgery). Ablation was performed using the JC HIFU system (HAIFU, Chongqing, China) with an ultrasonic device for real-time imaging. Clinical assessment included evaluation of pain severity using validated questionnaires with particular attention to the pain sensation scale (SES) with its affective and sensory component and the numeric rating scale (NRS). The average pain reduction after HIFU was 2.87 points on the NRS scale and 57.3 % compared to the mean baseline score (n = 15, 75 %) in 19 of 20 treated patients. Four patients did not report pain relief, however, the previous opioid medication could be stopped (n = 2) or the analgesic dosage could be reduced (n = 2). No pain reduction was achieved in one patient. Furthermore, after HIFU emotional as well as sensory pain aspects were significantly reduced (before vs. 1 week after HIFU, p pain scales). US-guided HIFU can be used for effective and early pain relief and reduction of emotional and sensory pain sensation in patients with locally advanced pancreatic cancer.

    Background: This study examined the comparative effectiveness of no treatment (NoTx), conventional fractionated radiotherapy (ConvRT), and stereotactic body radiotherapy (SBRT) in patients with inoperable stage I non-small cell lung cancer. This population based cohort also allowed us to examine what facility level characteristics contributed to improved outcomes. Methods: We included patients in the National Cancer Database from 2003 to 2006 with T1-T2N0M0 inoperable lung cancer (n = 13,036). Overall survival (OS) was estimated using Kaplan–Meier methods and Cox proportional hazard regression. Results: The median follow up was 68 months (interquartile range: 35–83 months) in surviving patients. Among the cohort, 52% received NoTx, 41% received ConvRT and 6% received SBRT. The 3-year OS was 28% for NoTx, 36% for ConvRT radiotherapy, and 48% for the SBRT cohort (p < 0.0001). On multivariate analysis, the hazard ratio for SBRT and ConvRT were 0.67 and 0.77, respectively, as compared to NoTx (1.0 ref) (p < 0.0001). Patients treated at a high volume facility vs. low volume facility had a hazard ratio of 0.94 vs. 1.0 (p = 0.01). Conclusions: Patients with early stage inoperable lung cancer treated with SBRT and at a high volume facility had a survival benefit compared to patients treated with ConvRT or NoTx or to those treated at a low volume facility

    Palliation of unresectable head and neck cancer remains a difficult problem. Because of excellent results reported by others with infusion of vinblastine, methotrexate, and 5-fluorouracil into the external carotid artery followed by irradiation before curative surgery, we applied this technic to 22 patients with advanced head and neck cancer. Fifteen patients from this group who had chemotherapy infusion followed by radiation therapy are compared with 21 patients who received radiation therapy alone. Both groups were similar in distribution of primary site, histology, and TNM stage. Of 15 patients, 14 (93%) had partial or complete tumor regression after both arterial chemotherapy infusion and irradiation, while 14 of 17 patients (82%) receiving primary irradiation had partial or complete response. Drug toxicity and complications related to infusion occurred in all patients. Most patients in both groups had short survivals (mean of 14.1 months in infusion chemotherapy and radiation vs 9.1 months in primary irradiation). One patient remains alive in the infusion group and two in the control group; however, all have recurrent disease. Results indicate a slight increase in survival time with the addition of infusion chemotherapy to irradiation in palliative treatment of head and neck cancer

    This brief letter describes a randomized trial in which radiotherapy is added to concomitant 5- fluorouracil and cisplatin therapy in patients with inoperable non-mestastatic squamous cell oesophageal cancer after palliative intubation. An interim analysis showed that patients randomized to observation had a median survival of 19 weeks while patients treated with radiotherapy, 5- fluorouracil and cisplatin had a median survival of 11 weeks. This difference in survival was due to the toxicity of the combined chemoradiotherapy and tube which resulted in early termination of the trial. (UK).

    In this prospective, non-randomized study we compare the results of simultaneous radiochemotherapy (RCT) with those of concomitant boost treatment (CBT) in advanced head and neck cancer. From January 1993 to March 1999, 77 patients were treated with cisplatin, 5-FU, and 70.2 Gy (accelerated split-course); from January 1995 to March 1999, a further 33 patients received CBT to a total dose of 72 Gy. Toxicities were prospectively recorded according to RTOG/EORTC criteria. Acute and subacute reactions did not differ significantly. Severe late effects (III/IV) remained anecdotal (one fistula). Therapy-associated mortalities were 3%(RCT) vs. 0% (CBT), most tumors responding well to therapy (CR + PR: RCT: 72%, CBT: 63%). The 2-year probabilities for freedom from locoregional progression amounted to 42% (RCT) and 31% (CBT); p > 0.05. Tumor-specific 2-year survival amounted to 40% (RCT) and 34% (CBT); p > 0.05. Both of the treatment concepts yield high remission rates with moderate toxicities. Nevertheless, median time to recurrence is still fairly short. We could not find any differences for local control and survival. For patients who are not able to complete the full three courses of radiochemotherapy, the concomitant boost schedule presents a good alternative

    To evaluate efficacy and toxicity of stereotactic body radiation therapy (SBRT) with CyberKnife {sup registered} (Accuray, Sunnyvale, CA, USA) in a selected cohort of primary, medically inoperable early-stage non-small cell lung cancer (NSCLC) patients. From 2012 to 2016, 106 patients (median age 74 years, range 50-94 years) with primary NSCLC were treated with SBRT using CyberKnife {sup registered}. Histologic confirmation was available in 87 patients (82%). For mediastinal staging, 92 patients (87%) underwent {sup 18}F-fluorodeoxyglucose positron-emission tomography (18-FDG-PET) and/or endobronchial ultrasound (EBUS)-guided lymph node biopsy or mediastinoscopy. Tumor stage (UICC8, 2017) was IA/B (T1a-c, 1-3 cm) in 86 patients (81%) and IIA (T2a/b, 3-5 cm) in 20 patients (19%). Depending on tumor localization, three different fractionation schedules were used: 3 fractions of 17Gy, 5 fractions of 11Gy, or 8 fractions of 7.5 Gy. Tracking was based on fiducial implants in 13 patients (12%) and on image guidance without markers in 88%. Median follow-up was 15 months (range 0.5-46 months). Acute side effects were mild (fatigue grade 1-2 in 20% and dyspnea grade 1-2 in 17%). Late effects were observed in 4 patients (4%): 3 patients developed pneumonitis requiring therapy (grade 2) and 1 patient suffered a rib fracture (grade 3). In total, 9/106 patients (8%) experienced a local recurrence, actuarial local control rates were 88% (95% confidence interval, CI, 80-96%) at 2 years and 77% (95%CI 56-98%) at 3 years. The median disease-free survival time was 27 months (95%CI 23-31 months). Overall survival was 77% (95%CI 65-85%) at 2 years and 56% (95%CI 39-73%) at 3 years. CyberKnife {sup registered} lung SBRT which allows for real-time tumor tracking and risk-adapted fractionation achieves satisfactory local control and low toxicity rates in inoperable early-stage primary lung cancer patients.

    Purpose: Recent clinical trials and meta-analyses have shown that both CHART (continuous hyperfractionated accelerated radiation therapy) and induction chemotherapy offer a survival advantage over conventional radical radiotherapy for patients with inoperable non-small cell-lung cancer (NSCLC). This multicenter randomized controlled trial (INCH) was set up to assess the value of giving induction chemotherapy before CHART. Methods and Materials: Patients with histologically confirmed, inoperable, Stage I-III NSCLC were randomized to induction chemotherapy (ICT) (three cycles of cisplatin-based chemotherapy followed by CHART) or CHART alone. Results: Forty-six patients were randomized (23 in each treatment arm) from 9 UK centers. As a result of poor accrual, the trial was closed in December 2007. Twenty-eight patients were male, 28 had squamous cell histology, 34 were Stage IIIA or IIIB, and all baseline characteristics were well balanced between the two treatment arms. Seventeen (74%) of the 23 ICT patients completed the three cycles of chemotherapy. All 42 (22 CHART + 20 ICT) patients who received CHART completed the prescribed treatment. Median survival was 17 months in the CHART arm and 25 months in the ICT arm (hazard ratio of 0.60 [95% CI 0.31-1.16], p = 0.127). Grade 3 or 4 adverse events (mainly fatigue, dysphagia, breathlessness, and anorexia) were reported for 13 (57%) CHART and 13 (65%) ICT patients. Conclusions: This small randomized trial indicates that ICT followed by CHART is feasible and well tolerated. Despite closing early because of poor accrual, and so failing to show clear evidence of a survival benefit for the additional chemotherapy, the results suggest that CHART, and ICT before CHART, remain important options for the treatment of inoperable NSCLC and deserve further study.

    To investigate the prognostic utility of the body mass index, severity of airflow obstruction, measures of exertional dyspnea, and exercise capacity (BODE) index in patients with inoperable non-small-cell lung cancer (NSCLC). One hundred consecutive patients with inoperable NSCLC and performance status 0 to 3 completed pulmonary function testing, the modified Medical Research Council dyspnea scale, a 6-minute walk test, and body mass index-the multidimensional 10-point BODE index. Cox proportional models were used to estimate the risk of all-cause mortality according to the BODE index with or without adjustment for traditional prognostic factors. Median follow-up was 31.5 months; 61 deaths (61%) were reported during this period. There was a significant univariate association between the BODE index score and mortality (adjusted p(trend) = 0.027). Compared with patients with a BODE index of 0, the adjusted hazard ratio for risk of death was 1.37 (95% confidence interval [CI], 0.74-2.55) for a BODE index of 1, 1.22 (95% CI, 0.45-3.25) for a BODE index of 2, and 2.44 (95% CI, 1.19-4.99) for a BODE index more than 2. The BODE index provided incremental prognostic information beyond that provided traditional markers of prognosis (adjusted p(trend) = 0.051). Every one-point increase in the BODE index, the risk of death increased by 25% (hazard ratio = 1.25; 95% CI, 1.27-4.64). The BODE index is a strong independent predictor of survival in inoperable NSCLC beyond traditional risk factors. Use of this multidimensional tool may improve risk stratification and prognostication in NSCLC.

Propensity score matching was used to reduce possible confounding factors. In total, 4,182 patients (2,091 matched pairs were included in the matched cohort. Cox proportional hazard model with time-dependent covariate were also applied to evaluate the association between metformin use and overall survival (OS.A total of 3,578 patients were metformin users at the time of diagnosis of NSCLC. Cox proportional hazard model with time-dependent covariate revealed that metformin use was associated with a significantly longer OS (HR: 0.85, 95.0% CI: 0.80-0.90. The survival benefit of metformin use was maintained after propensity score matching at a ratio of 1:1 (HR: 0.90, 95.0% CI: 0.84-0.97.Metformin use is associated with longer OS in inoperable NSCLC patients with diabetes, suggesting a potential anti-tumorigenic effect for metformin. Further research is needed to investigate the actual role of metformin in the treatment of NSCLC patients with diabetes.

    This study was performed to retrospectively evaluate the 10-year overall survival (OS), progression-free survival (PFS), and local control rates of patients with inoperable stage Ia non-small cell lung cancer (NSCLC) who underwent computed tomography (CT)-guided radiofrequency ablation (RFA) in a single center. Fifty patients with inoperable NSCLC underwent RFA between 2004 and 2016. Thoracic surgeons evaluated the patients and performed RFA under CT guidance. Follow-up CT and positron emission tomography/CT scans were obtained. Local control rates and recurrence patterns were analyzed. Seventy-three lesions in 50 patients (M:F = 22:28; median age: 73 years; range: 52-82 years) were treated with CT-guided RFA. The mean lesion size was 2.2 cm (range: 1-3 cm). No procedure-related deaths occurred. Low-grade fever was the most common post-ablation complication, with an incidence rate of 36%. The 1-, 2-, 3-, 5-, and 10-year OS rates of patients with Ia NSCLC were 96.0%, 86.5%, 67.1%, 36.3%, and 1%, respectively, and the 1-, 2-, 3-, and 5-year PFS rates were 94.0%, 77.5%, 43.5%, and 10.8%, respectively. The most common pattern of recurrence was local, and 15 patients with recurrence were treated with repeat RFA. Tumor size Ia NSCLC. Copyright © 2018 IJS Publishing Group Ltd.

    This review compares the safety and efficacy of boron neutron capture therapy (BNCT) in the treatment of previously irradiated, inoperable locoregional recurrent HNC patients and compares BNCT against the standard treatment of platinum-based chemotherapy. Our analysis of published clinical trials highlights efficacy of BNCT associated with mild side effects. However, the use of BNCT should be explored in stratified randomised trials. - Highlights: • BNCT can prolong median overall survival. • BNCT can be associated with severe adverse effects. • BNCT may be comparable to chemotherapy-based regimens. • BNCT may be comparable to re-irradiation techniques regimens in patients with low performance status.

    This study was designed to evaluate the feasibility and efficiency of giving cisplatin, etoposide, and OK-432 concurrently with conventional radiotherapy (RTx) for patient's with inoperable stage III, based on the TNM classification according to the International Union against Cancer staging system for lung cancer (1987) non-small cell lung cancer (NSCLC). From January 1992 to December 1994, 31 patients with cytologically or histologically confirmed stage III NSCLC were treated with RTx, to a total dose of 56-64 Gy, with concurrent daily oral administration of etoposide (25 mg) and cisplatin (20 mg) for 5 days during the third or fourth week from the start of RTx. The subcutaneous injection of 1 or 2 KE of OK-432, three times a week, for the duration of radiotherapy also started from the beginning of RTx. The number of eligible patients was 29 (26 men and 3 women). Their mean age was 66 years (range, 55-77 years). Six patients had an Eastern Cooperative Oncology Group performance status (PS) of 0; 15, 1; 8; 2. Three were stage IIIA, and 26, stage IIIB. Histologically, 2 had adenocarcinoma, 23, squamous cell carcinoma, and 4, large cell carcinoma. In 27 of the 29 patients, the RTx schedule was completed. There were no treatment-related deaths. Grade 4 toxicity (according to World Health Organisation criteria) leukopenia (700/μl) was observed in 1 patient. The response rate was 79% and the median survival was 17 months. Survival rates at 1, 2 and 3 years were 62%, 31%, and 21%, respectively. The local failure rate was 51%. The combination of cisplatin, etoposide, and OK-432, given concurrently with conventional RTx is feasible and effective for inoperable stage III NSCLC. (author)

    In a randomized trial, patients with inoperable non-small cell lung cancer with limited disease were randomly given either radiotherapy (42 Gy) or combination chemotherapy with cisplatin, 70 mg/m 2 , and etoposide, 100 mg/m 2 , given every third week with a maximum of 4 cycles. The patients were asked to fill in a questionnaire concerning psychosocial well-being, medical and treatment related symptoms, physical function and everyday activity. Of the chemotherapy patients 61% reported nausea 5 weeks after their last chemotherapy session and 44% had spells of vomiting. Only 14% of the radiotherapy patients had nausea and 5% vomited 14 weeks after start of treatment. Of the radiotherapy patients 64% experienced dysphagia compared to 8% of the chemotherapy patients 6 weeks after the start of treatment. (orig.)

    The role of IL6 in liver cancer linked to metabolic liver disease. Liver cancer is highly fatal, it has very few treatment options, and it is one of the few cancers whose incidence is rising worldwide. One poorly understood risk factor for liver cancer is obesity/metabolic disease (such as diabetes and fatty liver disease).

    Purpose: Prospectively designed randomized clinical study was undertaken to assess the efficacy of simultaneous application of irradiation, Mitomycin C, and Bleomycin in treatment of patients with inoperable head and neck carcinoma. Methods and Materials: Between March 1991 and October 1993, 49 patients with inoperable head and neck carcinoma were randomly assigned to receive either radiation therapy alone (group A) or radiotherapy combined with simultaneous application of Mitomycin C and Bleomycin (group B). Patients in both groups were irradiated five times weekly with 2 Gy to the total dose of 66-70 Gy. Chemotherapy regimen included intramuscular application of Bleomycin 5 units twice a week, with the planned dose being 70 units and Mitomycin C 15 mg/m 2 applied intravenously after delivery of 9-10 Gy of irradiation. The application of Mitomycin C was planned to be repeated on last day of radiotherapy in the dose of 10 mg/m 2 . In attempt to enhance the effect of chemotherapeutic drugs, patients in group B received also Nicotinamide, Chlorpromazine, and Dicoumarol. Results: The difference in complete response rate between both treatment groups (24% in group A and 63% in group B) was statistically significant (p = 0.015). The difference in response rate was much more pronounced in patients with oropharyngeal carcinoma only (18% in group A compared to 81% in group B; p = 0.0003), while for all other subgroups added together, there was observed no benefit of multidrug therapy. Median follow-up was 18 months. Disease-free survival of patients in group A (9%) was significantly lower then in group B (48%) (p 0.001). The difference between both treatment groups was even greater in patients with oropharyngeal carcinoma only: disease-free survival of these patients in group B was 66%, while in group A, all recurred (p = 0.00001). Conclusion: From results of our prospective randomized study it seems that the group of patients that received multidrug treatment with

    Various factors affecting /sup 67/Ga accumulation in liver cancer were studied in 38 patients with liver cancer (19 with hepatocellular carcinoma and 19 with metastatic liver cancer) who had received /sup 67/Ga-scintigraphy and liver scintigraphy. Besides histological types, the size, necrosis, vascularity and treatments of liver cancer, concentrations of transferrin (/sup 67/Ga binding protein) and iron in blood probably affected /sup 67/Ga accumulation in liver cancer.

    During the period from February 1991 through October 1992, we conducted a pilot phase II trial of an 'Alternating Radiotherapy and Chemotherapy' for 15 patients with localized inoperable non-small cell lung cancer. The combined regimen, consisting of ifosfamide 1.5 g/m 2 on days 1 through 3, cisplatin 80 mg/m 2 and vindesine 3 mg/m 2 on day 1, was given repeatedly every 4 weeks. Patients were treated in a split course fashion with combination chemotherapy sandwiched between radiation therapy (total dose 60 Gy). Of 15 evaluable patients, complete remission, partial remission and no change were obtained in 1, 13 and 1 patients, respectively, with an overall response rate of 93.3%. The median survival for all patients was 62 weeks. Hematologic toxicity was severe and was judged to be dose limiting. It was, however, clinically manageable with colony stimulating factor. These results indicate that this alternating radiotherapy and chemotherapy is feasible for localized non-small cell lung cancer and warrants further clinical trials. (author)

    Purpose: Stereotactic body radiation therapy for medically inoperable early-stage non-small cell lung cancer (NSCLC) offers excellent control rates. Most published series deal mainly with small (usually <4 cm), peripheral, solitary tumors. Larger tumors are associated with poorer outcomes (ie, lower control rates, higher toxicity) when treated with conventional RT. It is unclear whether SBRT is sufficiently potent to control these larger tumors. We therefore evaluated and examined the influence of tumor size on treatment outcomes after SBRT. Methods and Materials: Between October 2004 and October 2010, 185 medically inoperable patients with early (T1-T2N0M0) NSCLC were treated on a prospective research ethics board-approved single-institution protocol. Prescription doses were risk-adapted based on tumor size and location. Follow-up included prospective assessment of toxicity (as per Common Terminology Criteria for Adverse Events, version 3.0) and serial computed tomography scans. Patterns of failure, toxicity, and survival outcomes were calculated using Kaplan-Meier method, and the significance of tumor size (diameter, volume) with respect to patient, treatment, and tumor factors was tested. Results: Median follow-up was 15.2 months. Tumor size was not associated with local failure but was associated with regional failure (P=.011) and distant failure (P=.021). Poorer overall survival (P=.001), disease-free survival (P=.001), and cause-specific survival (P=.005) were also significantly associated with tumor size (with tumor volume more significant than diameter). Gross tumor volume and planning target volume were significantly associated with grade 2 or worse radiation pneumonitis. However, overall rates of grade ≥3 pneumonitis were low and not significantly affected by tumor or target size. Conclusions: Currently employed stereotactic body radiation therapy dose regimens can provide safe effective local therapy even for larger solitary NSCLC tumors (up to 5.7 cm

    Bronchial fistulas in cases of inoperable lung cancer caused by radiochemotherapy are quite refractory and generally cannot be surgically closed. A 45-year-old man with squamous cell carcinoma in the right lung underwent two courses of induction chemotherapy (135 mg CDDP, 5 mg VDS, 13.5 mg MMC) and radiation therapy (2 Gy x 22 times) for invasion of the right main bronchus, the pulmonary artery and superior vena cava. Just before the end of the second course, the empyem second to the bronchial fistula caused by tumor necrosis developed in the right upper bronchus, and fenestration was performed. After the operation, his condition improved remarkably, however the fistula enlarged into the right main bronchus and the purulent discharge flowed into the left lung. An expandable metallic stent (EMS) covered with polyuretane was inserted in the trachea and the left main bronchus to break aspiration pneumonia. As the covered EMS was too unstable to be fixed, a bare EMS was inserted in a stent-in-stent fashion. After the procedure he was followed at the O.P.D. and lived a relatively comfortable life for 9 months until his death due to tumor. We inserted the covered EMS in a stent-in-stent fashion to successfully obliterate a large bronchial fistula. (author)

    Radiotherapy remains the basic form of treatment in cases of non-small cell lung cancer (NSCLC) but there still exist controversies concerning optimal radiotherapy regimen and in particular, the total dose and fractionation schedules. To prove whether the question: if using an unconventional dose fractionation regimen (accelerated hyperfractionation) could improve the results of palliative teleradiotherapy patients with NSCLC. Between 1997 and 2000 in the Cancer Centre in Cracow (COOK) a controlled clinical trial was conducted in a group of 150 patients with locally advanced (III Deg) inoperable and unsuitable for radical radiotherapy NSCLC, with no major symptoms of the disease. In 76 patients conventionally fractionated radiotherapy was performed - 50 Gy in 25 fractions during 5 weeks (CF). 74 patients were irradiated twice a day (AHF); the dose per fraction was 1.25 Gy and the minimum interval between fractions - 6 hours. The total dose was 50 Gy in 40 fractions during 26 days. The probability of 12 months survival was 47.4% in the CF arm and 45.9% in the AHF arm; the probability of 24 months survival was 16.2% and 15.8%, respectively. In all 76 patients in CF arm the treatment was carried out in prescribed time without breaks. Out of 74 patients in the A HF group 8 (10,8%) did not complete the treatment and 2 of then died in 3rd and 4th week of treatment. The use of accelerated hyperfractionation does not improve the results of palliative teleradiotherapy in patients with locally advanced NSCLC without severe symptoms related to intrathoracic tumor. The treatment of choice in this group of patients os conventionally fractionated radiotherapy with a total dose of 50 Gy in 25 fractions in 5 week of treatment. (author)

    Definitive chemoradiotherapy (dCRT) is standard care for localised inoperable/unresectable oesophageal tumours. Many surgical series have reported on distribution of lymph node metastases (LNM) in resected patients. However, no data is available on the distribution of at-risk LN regions in this more unfavourable patient group. This study aimed to determine the spread of LNM using FDG-PET/CT, to compare it with the distribution in surgical series and to define its impact on the definition of elective LN irradiation (ENI). FDG-PET/CT images of patients with oesophageal cancer treated with dCRT (from 2003 to 2013) were reviewed to identify the anatomic distribution of FDG-avid LNs. Tumours were divided according to proximal, mid-thoracic or distal localisation. About 105 consecutive patients entered analysis. The highest numbers of FDG-avid LNs in proximal tumours were at LN station 101R (45%) and 106recL (35%). For mid-thoracic tumours at 104R (30%) and 105 (30%). For tumours located in the distal oesophagus, the most common sites were along the lesser curvature of the stomach (21%) and the left gastric artery (21%). Except for the supraclavicular and pretracheal nodes, there were no positive locoregional LNM found outside the standard surgical resection area. Our results show a good correlation between the distribution of nodal volumes at risk in surgical series and on FDG-PET/CT. The results can be used to determine target definition in dCRT for oesophageal cancer. For mid-thoracic tumours, the current target delineation guidelines may be extended based on the risk of node involvement, but more clinical studies are needed to determine if the potential harm of expanding the CTV outweighs the potential benefit.

    To compare the results of patients with locally advanced breast cancer receiving two different regimens Fluorouracil, Doxorubicin and Cyclophosphamide (FAC) and Paclitaxel and Carboplatin. Study Design: Comparative study. Place and Duration of Study: The Oncology Department, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from March 2007 to September 2008. Methodology: Patients with inoperable locally advanced breast cancer of stage were included. Sixteen patients were given FAC regimen and 9 patients were given Paclitaxel and Carboplatin, each combination was cycled after 21 days for four times. Before enrollment, detailed medical histories, physical examinations and performance status assessments were done as well as post chemotherapy evaluation with regular follow-up visits was done. Complete Response (CR, 100%) is defined as the disappearance of all known disease parameter i.e. disappearance in detectable tumour size, node free disease and surgery is possible. Paratial Response (PR, > 50%) was defined by 50% or greater decrease in the sum of the areas of bidimensionally measured lesions i.e. change of N2 to N1 or no status and some surgical procedure is possible to down stage the disease. Minor Response (MR) was defined as a decrease in the tumour insufficient to quality for partial resp once. Static disease or no evaluable reflected no significant change in disease and no evidence of new disease. Progression of disease (> 25%) was defined as a 25% or greater increase in the area of any lesion > 2 cm or in the sum of the products of the individual lesions or the appearance of new malignant lesions, surgery not possible. Results: Twenty five patients completed neoadjuvant chemotherapy. Sixteen (66%) patients received FAC and 9 (37%) patients received PC chemotherapy. Overall CR (breast and axilla) was 54%, PR was 16% and minor response (MR) was 8%. FAC treatment induced more emesis, mucositis, alopecia and cardiotoxicity. No death occurred

    Full Text Available Background. There is a considerable dissimilarity in the survival duration of the patients with gastric cancer. We aimed to assess the systemic inflammatory response (SIR and nutritional status of these patients before the commencement of chemotherapy to find the appropriate prognostic factors and define a new score for predicting metastasis. Methods. SIR was assessed using Glasgow Prognostic Score (GPS. Then a score was defined as prealbumin/CRP based prognostic score (PCPS to be compared with GPS for predicting metastasis and nutritional status. Results. 71 patients with gastric cancer were recruited in the study. 87% of patients had malnutrition. There was a statistical difference between those with metastatic (n=43 and those with nonmetastatic (n=28 gastric cancer according to levels of prealbumin and CRP; however they were not different regarding patient generated subjective global assessment (PG-SGA and GPS. The best cut-off value for prealbumin was determined at 0.20 mg/dL and PCPS could predict metastasis with 76.5% sensitivity, 63.6% specificity, and 71.4% accuracy. Metastatic and nonmetastatic gastric cancer patients were different in terms of PCPS (P=0.005. Conclusion. PCPS has been suggested for predicting metastasis in patients with gastric cancer. Future studies with larger sample size have been warranted.

    Purpose: To evaluate, in Japan Clinical Oncology Group study 0403, the safety and efficacy of stereotactic body radiation therapy (SBRT) in patients with T1N0M0 non-small cell lung cancer (NSCLC). Methods and Materials: Eligibility criteria included histologically or cytologically proven NSCLC, clinical T1N0M0. Prescribed dose was 48 Gy at the isocenter in 4 fractions. The primary endpoint was the percent (%) 3-year overall survival. The threshold % 3-year survival to be rejected was set at 35% for inoperable patients, whereas the expected % 3-year survival was 80% for operable patients. Results: Between July 2004 and November 2008, 169 patients from 15 institutions were registered. One hundred inoperable and 64 operable patients (total 164) were eligible. Patients' characteristics were 122 male, 47 female; median age 78 years (range, 50-91 years); adenocarcinomas, 90; squamous cell carcinomas, 61; others, 18. Of the 100 inoperable patients, the % 3-year OS was 59.9% (95% confidence interval 49.6%-68.8%). Grade 3 and 4 toxicities were observed in 10 and 2 patients, respectively. No grade 5 toxicity was observed. Of the 64 operable patients, the % 3-year OS was 76.5% (95% confidence interval 64.0%-85.1%). Grade 3 toxicities were observed in 5 patients. No grade 4 and 5 toxicities were observed. Conclusions: Stereotactic body radiation therapy for stage I NSCLC is effective, with low incidences of severe toxicity. This treatment can be considered a standard treatment for inoperable stage I NSCLC. This treatment is promising as an alternative to surgery for operable stage I NSCLC.

    Purpose: To performed a systematic review and pooled analysis to compare clinical outcomes of stereotactic body radiation therapy (SBRT) and radiofrequency ablation (RFA) for the treatment of medically inoperable stage I non-small cell lung cancer. Methods and Materials: A comprehensive literature search for published trials from 2001 to 2012 was undertaken. Pooled analyses were performed to obtain overall survival (OS) and local tumor control rates (LCRs) and adverse events. Regression analysis was conducted considering each study's proportions of stage IA and age. Results: Thirty-one studies on SBRT (2767 patients) and 13 studies on RFA (328 patients) were eligible. The LCR (95% confidence interval) at 1, 2, 3, and 5 years for RFA was 77% (70%-85%), 48% (37%-58%), 55% (47%-62%), and 42% (30%-54%) respectively, which was significantly lower than that for SBRT: 97% (96%-98%), 92% (91%-94%), 88% (86%-90%), and 86% (85%-88%) (P<.001). These differences remained significant after correcting for stage IA and age (P<.001 at 1 year, 2 years, and 3 years; P=.04 at 5 years). The effect of RFA was not different from that of SBRT on OS (P>.05). The most frequent complication of RFA was pneumothorax, occurring in 31% of patients, whereas that for SBRT (grade ≥3) was radiation pneumonitis, occurring in 2% of patients. Conclusions: Compared with RFA, SBRT seems to have a higher LCR but similar OS. More studies with larger sample sizes are warranted to validate such findings.

    Purpose: In 2007, we published our initial experience in treating inoperable non-small-cell lung cancer (NSCLC) with intensity-modulated radiation therapy (IMRT). The current report is an update of that experience with long-term follow-up. Methods and Materials: Patients in this retrospective review were 165 patients who began definitive radiotherapy, with or without chemotherapy, for newly diagnosed, pathologically confirmed NSCLC to a dose of {>=}60 Gy from 2005 to 2006. Early and late toxicities assessed included treatment-related pneumonitis (TRP), pulmonary fibrosis, esophagitis, and esophageal stricture, scored mainly according to the Common Terminology Criteria for Adverse Events 3.0. Other variables monitored were radiation-associated dermatitis and changes in body weight and Karnofsky performance status. The Kaplan-Meier method was used to compute survival and freedom from radiation-related acute and late toxicities as a function of time. Results: Most patients (89%) had Stage III to IV disease. The median radiation dose was 66 Gy given in 33 fractions (range, 60-76 Gy, 1.8-2.3 Gy per fraction). Median overall survival time was 1.8 years; the 2-year and 3-year overall survival rates were 46% and 30%. Rates of Grade {>=}3 maximum TRP (TRP{sub max}) were 11% at 6 months and 14% at 12 months. At 18 months, 86% of patients had developed Grade {>=}1 maximum pulmonary fibrosis (pulmonary fibrosis{sub max}) and 7% Grade {>=}2 pulmonary fibrosis{sub max}. The median times to maximum esophagitis (esophagitis{sub max}) were 3 weeks (range, 1-13 weeks) for Grade 2 and 6 weeks (range, 3-13 weeks) for Grade 3. A higher percentage of patients who experienced Grade 3 esophagitis{sub max} later developed Grade 2 to 3 esophageal stricture. Conclusions: In our experience, using IMRT to treat NSCLC leads to low rates of pulmonary and esophageal toxicity, and favorable clinical outcomes in terms of survival.

    Neuropsychological tests were used to evaluate possible central nervous system dysfunction in patients treated with chemotherapy. Ninety-five patients with non-small cell lung cancer limited disease were randomized to either radiotherapy (2.8 Gyx15) or combination chemotherapy with cisplatin and etoposide. In order to evaluate cognitive functions three neuropsychological tests were applied: Trail Making, Benton Visual Retention Test and Verbal Learning. Changes in the patients' test scores before and after treatment were compared. The chemotherapy patients showed reduced performance on some of the neuropsychological tests compared to the radiotherapy group. This indicates a treatment related effect on the central nervous system, possibly caused by the combination chemotherapy.

    To date, gemcitabine-based or fluoropyrimidine-based regimens are recommended for unresectable advanced biliary tract cancer. Then, we conducted a phase I study of gemcitabine/cisplatin and S-1 that is an oral fluoropyrimidine. The aim of this study was to determine the dose-limiting toxicity (DLT), maximum-tolerated dose, and a recommended phase II dose of S-1. Response was assessed as a secondary endpoint. Patients who have been diagnosed with unresectable or postoperative recurrent biliary tract cancer received cisplatin (25 mg/m² i.v. for 120 min) followed by gemcitabine (1,000 mg/m² i.v. for 30 min) on days 1 and 8, and oral S-1 on alternate days; this regimen was repeated at 21-day intervals. A standard '3 + 3' phase I dose-escalation design was adopted. This study was registered with University hospital Medical Information Network (UMIN) Center in Japan, number UMIN000008415. Twelve patients were evaluable in this study. No patients developed DLTs. Recommended dose of S-1 was 80 (day. One patient could achieve conversion to curative surgery. This phase I study was performed safely and demonstrated encouraging response.

    Patients with a newly diagnosed non-small cell lung cancer (NSCLC) stage IIIB are offered chemoradiotherapy, as proposed by the current guidelines. This combination treatment is facilitated by the coexistence of corresponding departments in the same establishment. The geographical disparity of these health facilities influences patients’ willingness to be treated and may influence their survival. This is an observational study that compares the survival of two groups of patients with NSCLC stage IIIB: those treated with chemoradiotherapy versus those treated only with chemotherapy. These two comparable groups were formed exclusively by patients’ and/or their families’ decisions. One hundred fifteen consecutive NSCLC stage IIIB patients were included in the study. All were hospitalized in the biggest Chest Disease Hospital in Athens and were offered sequential chemoradiotherapy. Only 54 patients opted for the proposed treatment, while 61 decided to be treated with chemotherapy only, denying continuing their treatment in another health care unit (radiotherapy). Their survival and related factors were analyzed. Mean overall survival was estimated 10 months (95% confidence interval [CI]: 7.96–12.04). Patients treated with chemoradiotherapy had almost double overall survival compared to those under chemotherapy (P = 0.001): 13.6 months (95% CI: 12.3–14.9) versus 7.5 (95% CI: 6.1–8.9). Patients aged ≤ 65 years (P < 0.001), smokers (P < 0.001), and those without a cancer history (P < 0.001) survived longer. The lack of a radiotherapy department in a hospital providing chemotherapy impedes the application of current guidelines advocating combined radiochemotherapy. When recommended radiotherapy after six chemo cycles, half of the patients are unwilling to be displaced and do not follow the recommendations. This has an impact on patient survival

    Purpose: The results of a pilot study using S-1/low-dose cisplatin/radiotherapy led us to hypothesize that the initial chemoradiotherapy regimen would induce a 70% efficacy rate with a 10% pathologic complete response rate. Patients and Methods: Only patients with unresectable or incurable advanced gastric cancer were eligible. The patients received induction S-1 and cisplatin therapy with radiotherapy followed by chemotherapy alone. Results: Of the 30 patients recruited and assessed, 29 were eligible for clinical evaluation of measurable lesions. The response rate was 65.5%, with 19 with a partial response, 8 with no change, and 2 with progressive disease of 29 patients. Of the 30 patients recruited, 10 (33.3%) underwent stomach resection and D2 LN dissections. The pathologic complete response rate was 13.3% (4 patients), and the R0 resection rate was 100% (10 patients). The survival analysis showed a median survival time of 25 months. Grade 3 toxicity occurred in 66.7% for leukocytopenia, 33.3% for thrombocytopenia, 23.3% for nausea and appetite loss, and 6.7% for anemia, diarrhea, and renal dysfunction. Although all the patients had been hospitalized with a poor performance status with a giant tumor, 97% (29 of 30) could be discharged after the first cycle, resulting in an improvement in quality of life. Conclusion: Chemoradiotherapy could be a powerful regimen for controlling tumor progression in advanced gastric cancer, improving patients' quality of life with tolerable toxicity. A complete histologic response rate of >10% would be expected, even for large tumors with metastatic lesions

  18. Liver cancer and selective internal radiation therapy

    International Nuclear Information System (INIS)

    Sutton, C.

    2002-01-01

    Liver cancer is the biggest cancer-related killer of adults in the world. Liver cancer can be considered as two types: primary and secondary (metastatic). Selective Internal Radiation Therapy (SIRT) is a revolutionary treatment for advanced liver cancer that utilises new technologies designed to deliver radiation directly to the site of tumours. SIRT, on the other hand, involves the delivery of millions of microscopic radioactive spheres called SIR-Spheres directly to the site of the liver tumour/s, where they selectively irradiate the tumours. The anti-cancer effect is concentrated in the liver and there is little effect on cancer at other sites such as the lungs or bones. The SIR-Spheres are delivered through a catheter placed in the femoral artery of the upper thigh and threaded through the hepatic artery (the major blood vessel of the liver) to the site of the tumour. The microscopic spheres, each approximately 35 microns (the size of four red blood cells or one-third the diameter of a strand of hair), are bonded to yttrium-90 (Y-90), a pure beta emitter with a physical half-life of 64.1 hours (about 2.67 days). The microspheres are trapped in the tumour's vascular bed, where they destroy the tumour from inside. The average range of the radiation is only 2.5 mm, so it is wholly contained within the patient's body; after 14 days, only 2.5 percent of the radioactive activity remains. The microspheres are suspended in water for injection. The vials are shipped in lead shields for radiation protection. Treatment with SIR-Spheres is generally not regarded as a cure, but has been shown to shrink the cancer more than chemotherapy alone. This can increase life expectancy and improve quality of life. On occasion, patients treated with SIR-Spheres have had such marked shrinkage of the liver cancer that the cancer can be surgically removed at a later date. This has resulted in a long-term cure for some patients. SIRTeX Medical Limited has developed three separate cancer

    Background: According to reports of Durrant et al. [19] and Berry et al. [5] it was concluded that non-operable non-small cell lung tumors cannot be cured. In this consequence initiation of radiotherapy was fixed at the beginning of symptoms. However, long-time survivors in our follow-up lead us to analyse not only quality of life and secondary therapeutic effects but also this special group with the results of the whole collective treated in the same period of interest. Results: From 145 patients with non-small cell lung cancer 64.1% (93/145) survived 6 months, 42.8% (62/145) 1 year, 19.3% (28/145) 2 years and 7.6% (11/145) 5 and 4.8 (7/145) more than 10 years. According to TN-stages T1-4 N0 collective had a survival rate of 67.8% (40/59) after half a year, 50.8% (30/59) after 1 year, 23.7% (14/59) after 2 and 11.9% (7/59) after 5 years. Treatment results by patients with positive lymph nodes T1-4 N1-3 after the same intervals are: 61.6% (53/86), 37.2% (32/86), 16.2% (14/86) respectively 4.7% (4/86). In the period 5 to 10 years after irradiation 4 patients died, 1 with local relapse, 2 with contralateral lung cancer - ipsilateral region was endoscopically and histologically free of tumor - and 1 patient in consequence of heart insufficency of several years. Seven patients are still alive after 13 to 16 years. There is no sign of tumor in this group or any effects limitating their quality of life. Twenty-four patients received less than 50 Gy. All patients but 2 did not survive 6 months. One patient survived half a year and 1 patient 2 years. (orig./AJ) [Deutsch] Hintergrund: Nach Publikationen von Durrant et al. [19] und Berry et al.

    2008-01-01

    Purpose: We report the toxicity profile and pharmacokinetic data of a schedule-dependent chemoradiation regimen using pulsed low-dose paclitaxel for radiosensitization in a Phase I study for inoperable non-small-cell lung cancer. Methods and Materials: Paclitaxel at escalating doses of 15 mg/m 2 , 20 mg/m 2 , and 25 mg/m 2 were infused on Monday, Wednesday, and Friday with daily chest radiation in cohorts of 6 patients. Daily radiation was delayed for maximal G2/M arrest and apoptotic effect, an observation from preclinical investigations. Plasma paclitaxel concentration was determined by high-performance liquid chromatography. Results: Dose-limiting toxicities included 3 of 18 patients with Grade 3 pneumonitis and 3 of 18 patients with Grade 3 esophagitis. There was no Grade 4 or 5 pneumonitis or esophagitis. There was also no Grade 3 or 4 neutropenia, thrombocytopenia, anemia or neuropathy. For Dose Levels I (15 mg/m 2 ), II (20 mg/m 2 ), and III (25 mg/m 2 ), the mean peak plasma level was 0.23 ± 0.06 μmol/l, 0.32 ± 0.05 μmol/l, and 0.52 ± 0.14 μmol/l, respectively; AUC was 0.44 ± 0.09 μmol/l, 0.61 ± 0.1 μmol/l, and 0.96 ± 0.23 μmol/l, respectively; and duration of drug concentration >0.05 μmol/l (t > 0.05 μmol/l) was 1.6 ± 0.3 h, 1.9 ± 0.2 h, and 3.0 ± 0.9 h, respectively. Conclusion: Pulsed low-dose paclitaxel chemoradiation is associated with low toxicity. Pharmacokinetic data showed that plasma paclitaxel concentration >0.05 μmol/l for a minimum of 1.6 h was sufficient for effective radiosensitization

    Conclusion: We identify male gender, weight loss greater than 10% and age as independent prognostic factors for patients treated with medically inoperable NSCLC treated with SABR or hypofractionated radiotherapy. Based on our survival models, age alone can be used interchangeably with aCCI or CCI plus age with the same prognostic value. Age is more reliably recorded, less prone to error and therefore a more useful metric than Charlson score in this group of patients.

    Purpose: To report the results of high-dose conformal irradiation and examine incidental nodal irradiation and nodal failure in patients with inoperable early-stage non-small-cell lung cancer (NSCLC). Methods and Materials: This analysis included patients with inoperable CT-staged T1-3N0M0 NSCLC treated on our prospective dose-escalation trial. Patients were treated with radiation alone (total dose, 63-102.9 Gy in 2.1-Gy daily fractions) with a three-dimensional conformal technique without intentional nodal irradiation. Bilateral highest mediastinal and upper/lower paratracheal, prevascular and retrotracheal, sub- and para-aortic, subcarinal, paraesophageal, and ipsilateral hilar regions were delineated individually. Nodal failure and doses of incidental irradiation were studied. Results: The potential median follow-up was 104 months. For patients who completed protocol treatment, median survival was 31 months. The actuarial overall survival rate was 86%, 61%, 43%, and 21% and the cause-specific survival rate was 89%, 70%, 53%, and 35% at 1, 2, 3, and 5 years, respectively. Weight loss (p = 0.008) and radiation dose in Gy (p = 0.013) were significantly associated with overall survival. In only 22% and 13% of patients examined did ipsilateral hilar and paratracheal (and subaortic for left-sided tumor) nodal regions receive a dose of ≥40 Gy, respectively. Less than 10% of all other nodal regions received a dose of ≥40 Gy. No patients failed initially at nodal sites. Conclusions: Radiation dose is positively associated with overall survival in patients with medically inoperable T1-3N0 NSCLC, though long-term results remain poor. The nodal failure rate is low and does not seem to be due to high-dose incidental irradiation

    Purpose: The standard treatment for patients with unresectable or medically inoperable non-small cell lung cancer (NSCLC) and good prognostic factors (e.g., weight loss [WL] ≤5% and Karnofsky performance status [KPS] ≥70) is induction chemotherapy followed by definitive radiotherapy to the primary site at 1.8-2.0 Gy per fraction with a total dose of 60-63 Gy to the target volume. Patients with poor prognostic factors usually receive radiotherapy alone, but the fractionation schedule and total dose have not been standardized. To attempt to optimize irradiation doses and schedule, we compared the effectiveness of accelerated radiotherapy (ACRT) alone to 45 Gy at 3 Gy per fraction with standard radiation therapy (STRT) of 60-66 Gy at 2 Gy per fraction in regard to tumor response, local control, distant metastasis, toxicity, and survival. Methods and Materials: Fifty-five patients treated with radiation for NSCLC at The University of Texas M. D. Anderson Cancer Center between 1990 and 1994 were identified. All 55 patients had node-positive, and no distant metastasis (N+, M0) of NSCLC. Two cohorts were identified. One cohort (26 patients) had borderline poor prognostic factors (KPS less than 70 but higher than 50, and/or WL of more than 5%) and was treated with radiotherapy alone to 45 Gy over 3 weeks at 3 Gy/fraction (ACRT). The second cohort (29 patients) had significantly better prognostic factors (KPS ≥70 and WL ≤5%) and was treated to 60-66 Gy over 6 to 6((1)/(2)) weeks at 2 Gy per fraction (STRT) during the same period. Results: In the first cohort treated by ACRT, the distribution of patients by AJCC stage was IIB 8%, IIIA 19%, and IIIB 73%. Sixty-two percent had KPS 5%. The maximum response rate as determined by chest X-ray was 60% among 45 of 55 patients who were evaluable for response: combined complete responses (20%) and partial responses (40%). Overall survival in these patients was 13% at 2 and 5 years, with a locoregional control rate of 42% and a

    The aims of UKWT2 included consolidating the results for stage III patients obtained in UKWT1 and improving the outcome for patients with inoperable tumours by giving vincristine, actinomycin-D and doxorubicin in an intensive schedule (Intensive AVA). The second UK WT trial (UKWT2) ran between July 1986 and September 1991 accruing 448 patients. One hundred and six patients were diagnosed and treated for stage III disease. Six had clear cell sarcoma of the kidney (CCSK) and seven had rhabdoid tumours of the kidney (RTK) and are analysed separately. One other patient was excluded from overall analysis. Ninety-two patients were followed for a median of 115 months. Seventy-five received standard chemotherapy and abdominal radiotherapy according to protocol. Seventeen had stage III disease at immediate nephrectomy, but radiotherapy was omitted by physician choice. Thirty-three patients had inoperable disease at diagnosis and received pre-nephrectomy chemotherapy. Overall survival (OS) at 4 years for stage III favourable histology (FH) patients receiving abdominal RT was 83% (CI: 73-89). For children with stage III disease in whom RT was omitted the OS was 82% (CI: 59-97) and for inoperable disease 94% (CI: 78-98). The overall and event-free survival (EFS) of children with stage III CCSK was 100% and was achieved with the majority of patients not receiving radiotherapy (CI: 48-100). Three of seven children with RTK are alive EFS and OS 43% (CI: 10-73). For patients treated by abdominal radiotherapy the overall local control rate was 94.4% (CI: 86.4-98.5*%), 96.7% (CI: 88.5-99.6%) for flank RT and 83.3% (51.6-98.0%) for whole abdominal radiotherapy (WRT). The outcome for stage III FH disease was similar to that reported for UKWT1 and NWTS-3. The combination of abdominal RT together with 3-drug chemotherapy achieves a high abdominal tumour control rate. Flank RT is probably sufficient for localised tumour rupture. The high cure rates for children in this trial with

    Full Text Available Abstract Background While conventionally fractionated radiation therapy alone is an acceptable option for poor prognostic patients with unresectable stage III NSCLC, we hypothesized that accelerated hypofractionated radiotherapy will have similar efficacy without increasing toxicity. Methods This is a retrospective analysis of 300 patients diagnosed with stage III NSCLC treated between 1993 and 2009. Patients included in the study were medically or surgically inoperable, were free of metastatic disease at initial workup and did not receive concurrent chemotherapy. Patients were categorized into three groups. Group 1 received 45 Gy in 15 fractions over 3 weeks (Accelerated Radiotherapy (ACRT while group 2 received 60-63 Gy (Standard Radiation Therapy 1 (STRT1 and group 3 received > 63 Gy (Standard Radiation Therapy (STRT2. Results There were 119 (39.7% patients in the ACRT group, 90 (30.0% in STRT1 and 91 (30.3% in STRT2. More patients in the ACRT group had KPS ≤ 60 (p 5% (p = 0.002, and had stage 3B disease (p Conclusions Despite the limitations of a retrospective analysis, our experience of accelerated hypofractionated radiation therapy with 45 Gy in 15 fractions appears to be an acceptable treatment option for poor performance status patients with stage III inoperable tumors. Such a treatment regimen (or higher doses in 15 fractions should be prospectively evaluated using modern radiation technologies with the addition of sequential high dose chemotherapy in stage III NSCLC.

    Objective: Evaluation of the efficacy and tolerability of transarterial chemoembolization with gemcitabine in patients with inoperable liver metastases of breast cancer. Materials and methods: Open-label, prospective non-randomized single-center study design; patients had previous chemotherapy including anthracyclines and/or taxanes in the metastatic setting, adequate bone marrow reserve, sufficient liver/renal function, no centralnervous system metastases, Karnovsky-performance-status >70%, and life expectancy >12 weeks. Forty-three patients were enrolled (median 58 years, range 48–71). A suspension of gemcitabine 1.200 mg/m{sup 2}, 2–10 ml/m{sup 2} of Lipiodol, and 5 ml of a degradable starch microsphere (Embocept) suspension, were administered intra-arterially up to 3 times with a 4-weaks-interval. Dose-limiting toxicit is defined as grade 4 thrombocytopenia, neutropenia, or nonhematologic toxicity > grade 3. Tumor response was evaluated by magnetic resonance (MRI) and computed tomography (CT) imaging. Results: All patients tolerated the treatment well; with no dose limiting toxicities. Imaging follow-up according to the RECIST-criteria (Response Evaluation Criteria in Solid Tumors) revealed a partial response in 3 patients, stable disease in 16 patients and progression in 22 patients. The progression free survival was 3.3 months. A significant correlation exists only with the factor vascularization: strongly vascularized tumors show a significantly lowered response. Patients with complete or partial response and the main fraction of the stable disease group showed in the MRI and angiography only a moderate vascularization. The resulting estimate of the total survival rate amounts to a median of 10.2 months. Conclusion: Transarterial chemoembolization with gemcitabine is well tolerated and provides an alternative treatment method for patients with liver metastases of breast cancer.

    This paper describes bases of radiotherapy (RT) of liver cancer for its application, efficacy, clinical target volume (CTV) and characteristics, dose fractionation and its theory, 2D/3D irradiation, evaluation, and safety. The description here is leading to execute the Guideline 200X to be issued in a near future by the Japanese College of Radiology, and is supplementary to the Guideline in nature. The Guideline is to incorporate the recent progresses of the therapy to complement the previous Guideline 2004. Thus here are described the application of RT to unresectable hepatoma in relation to intervention; characteristics of RT including dose-effect relationships, morphological characteristics of intravascular tumor thrombi (ITT) and CTV, dose fractionation and a/b ratio (liver 2.5 vs hepatoma 7.4), focal lesion in parenchyma, ITT and RT, lymph metastasis, arteriovenous shunt and dissemination, and desensitization in bone and adrenal metastases; prediction of radiation liver damage; and adverse effect by radiation and its control. The evidenced bases of RT are still poor in this field, but the fact that hepatoma, highly sensitive to radiation, exhibits clear dose-response ensures its efficacy if the problems of low tolerance and of breathing movement at irradiation can be solved.

    Full Text Available Objective: To study the effect of selective hepatic inflow occlusion during liver cancer resection on liver ischemia-reperfusion injury. Methods: A total of 68 patients with primary liver cancer who underwent left liver resection in our hospital between May 2012 and August 2015 were selected for study and divided into group A (selective hepatic inflow occlusion of left liver and group B (Prignle hepatic inflow occlusion according to different intraoperative blood occlusion methods, serum was collected before and after operation to determine liver enzyme content, the removed liver tissue was collected to determine energy metabolism indexes, inflammation indexes and oxidative stress indexes. Results: 1 d, 3 d and 5 d after operation, GPT, GOT, GGT, LDH and ALP content in serum of both groups were significantly higher than those before operation, and GPT, GOT, GGT, LDH and ALP content in serum of group A 1 d, 3 d and 5 d after operation were significantly lower than those of group B; ATP, ADP, AMP, PI3K, AKT, GSK3β, T-AOC, PrxI and Trx content in liver tissue of group A were significantly higher than those of group B while PTEN, IL-12p40, MDA and MPO content were significantly lower than those of group B. Conclusions: Selective hepatic inflow occlusion during liver cancer resection can reduce the liver ischemia-reperfusion injury, improve the energy metabolism of liver cells and inhibit inflammation and oxidative stress in liver tissue.

    Radionuclide liver scans were obtained in 89 preoperative patients with gastric cancer. Eight showed definite defects on liver scans. At laparotomy, 14 patients were found to have liver involvement secondary to gastric cancer. The sensitivity of liver scans to predict liver involvement is 57% (8/14), and the specificity is 100% (75/75). The patients with definite defects on liver scans had a lower rate of palliative resection of the primary tumors (2/8) than the patients with liver involvement and no scan abnormality (4/6). The patients with advanced lesions but without liver involvement had the highest probability of resecting the primary tumors (57/63 : 47 radical, and 10 palliative). Normal serum levels of liver chemistries did not preclude the presence of defects on liver scans. Additional three patients were found to have cirrhosis of the liver solely based on liver scans, which was confirmed at laparotomy. Radionuclide liver scans can predict liver involvement with very few false positives, and may discriminate patients unsuitable for laparotomy even with palliative intent.

    Twenty-one nodules of hepatocellular carcinoma (HCC) and eighteen nodules of liver metastasis, which were confirmed pathologically, were investigated by MRI before operation and MRI of resected liver specimen. Pre-operative MRI pointed out all HCCs and seventeen metastases. STIR method was most useful for detection of HCCs. T2WI and STIR method were most useful for detection of liver metastases. Pre-operative MRI also revealed 93% of capsule formation, 29% of septal formation, 75% of fatty metamorphosis of HCC and 75% of necrosis of liver metastasis, and post-operative MRI of resected specimens revealed 100% of capsule formation, 71% of septal formation, 75% of fatty metamorphosis of HCC and 88% of necrosis of liver metastasis. T1WI showed a high intensity halo surrounding metastasis. This characteristic peripheral halo was seen in 22% of metastases. These findings corresponded to pathological feature of liver cancer. MRI was thought to be useful diagnostic modality of liver cancer. (author)

    The substantial heterogeneity and hierarchical organization in liver cancer support the theory of liver cancer stem cells (LCSCs). However, the relationship between chronic hepatic inflammation and LCSC generation remains obscure. Here, we observed a close correlation between aggravated inflammation and liver progenitor cell (LPC) propagation in the cirrhotic liver of rats exposed to diethylnitrosamine. LPCs isolated from the rat cirrhotic liver initiated subcutaneous liver cancers in nonobese diabetic/severe combined immunodeficient mice, suggesting the malignant transformation of LPCs toward LCSCs. Interestingly, depletion of Kupffer cells in vivo attenuated the LCSC properties of transformed LPCs and suppressed cytokeratin 19/Oval cell 6-positive tumor occurrence. Conversely, LPCs cocultured with macrophages exhibited enhanced LCSC properties. We further demonstrated that macrophage-secreted tumor necrosis factor-α triggered chromosomal instability in LPCs through the deregulation of ubiquitin D and checkpoint kinase 2 and enhanced the self-renewal of LPCs through the tumor necrosis factor receptor 1/Src/signal transducer and activator of transcription 3 pathway, which synergistically contributed to the conversion of LPCs to LCSCs. Clinical investigation revealed that cytokeratin 19/Oval cell 6-positive liver cancer patients displayed a worse prognosis and exhibited superior response to sorafenib treatment. Our results not only clarify the cellular and molecular mechanisms underlying the inflammation-mediated LCSC generation but also provide a molecular classification for the individualized treatment of liver cancer.

    Purpose: Results of radical radiotherapy in the treatment of inoperable NSCLC can be improved by either concurrent daily low-dose Cisplatin as radiosensitizer (Shaake-Koning, N Engl J Med, 1992; 326: 524) or by using neoadiuvant chemotherapy (Dillman, N Engl J Med, 1990; 323: 940). The aim of present study was to evaluate the activity and feasibility of a new chemo-radiotherapy (CT-RT) regimen in which both strategies of RT improvement will be used. Methods: Thirty consecutive patients (pts) were treated with induction CT (Cisplatin 100 mg/m{sup 2} i.v. day 1,22 + Vinblastine 5 mg/m{sup 2} i.v. day 1,8,15,22,29) followed by RT (60 Gy/30 fractions in 6 wks) combined with Cisplatin 5 mg/m{sup 2} daily before RT. Patients' characteristics were: 29 pts were male and 1 female; median age 60.5 yrs (range 44-69); median PS 1 (range 0-1); 21 squamous cell carcinoma and 9 adenocarcinoma; stage III A in 9 pts and stage IIIB in 21 pts. Results: Twenty-three pts were evaluable for RT plus daily Cisplatin toxicity and 29 for CT toxicity (according to WHO). For RT plus daily cisplatin hematological toxicity consisted of grade III leukopenia in 22%, grade III anemia 9% and grade III thrombocytopenia in 9% of pts. Only 2 patients developed severe esophagitis. Only one case of radiation pneumonitis was reported. For induction CT hematological toxicity consisted of grade III-IV leukopenia in 31%, grade II anemia 10% and grade IV thrombocitopenia in 14% of cases. Non-hematological toxicity consisted mainly of grade I peripheral neuropaty and occured in 17% of pts. One case of minor hearing loss and 4 cases of tinnitus were observed at the end of treatment. Twenty-seven pts were evaluable for response. Response rate was 59% with 7 CRs (26%) and 9 PRs (33%); 1 patient had SD (4%), 5 pts PD (20%) and 5 pts (19%) died early (3 for early progression, 1 for toxicity and 1 for cardiac failure). All pts with CR are still alive with a median event-free survival of 23.9 months (range 12

    The incidence of hepatocellular carcinoma is increasing. Most patients present beyond potentially curative options and are usually affected by underlying cirrhosis. In this scenario, transarterial therapies, such as radioembolization, are rapidly gaining acceptance as a potential therapy for hepatocellular carcinoma and liver metastases. Radioembolization is a catheter-based liver-directed therapy that involves the injection of micron-sized embolic particles loaded with a radioisotope by use of percutaneous transarterial techniques. Cancer cells are preferentially supplied by arterial blood and normal hepatocytes by portal venous blood; therefore, radioembolization specifically targets tumor cells with a high dose of lethal radiation and spares healthy hepatocytes. The antitumor effect mostly comes from radiation rather than embolization. The most commonly used radioisotope is yttrium-90. The commercially available devices are TheraSphere (glass based; MDS Nordion, Ottawa, Canada) and SIR-Sphere (resin based; Sirtex, Lane Cove, Australia). The procedure is performed on an outpatient basis. The incidence of complications is comparatively less than other locoregional therapies and may include nausea, fatigue, abdominal pain, hepatic dysfunction, biliary injury, fibrosis, radiation pneumonitis, gastrointestinal ulcers, and vascular injury. However, these complications can be avoided by meticulous pretreatment assessment, careful patient selection, and adequate dosimetry. This article focuses on both the technical and clinical aspects of radioembolization with emphasis on patient selection, uses and complications. Copyright © 2011 Elsevier Inc. All rights reserved.

    Liver diseases are common worldwide and hepatocellular carcinoma (HCC) is the commonest primary liver cancer. It has varied incidences globally but it is particularly common in Africans with a high prevalence in Nigerians where it accounted for the 4th commonest cause of death in both sexes between 1976 and 1995 (table 1). Similarly its incidence has remained persistently high between 3.1 and 8.6% per annum. Hepatocellular carcinoma occurs among all socio-economic classes of the population and is commonest among the 30-50 year group, two decades earlier than in the Caucasians and Americans. However, patients with HCC present in several patterns with majority having sudden onset of abdominal pain and swelling which is usually progressive, running an aggressive course. These patients who are in their prime of life arrive late in hospitals when the disease is advanced and is unlikely to respond to the usual modalities of therapy hence the disease has a gloomy picture. The solution is EARLY DIAGNOSIS with PROMPT THERAPY for achieving possible CURE of the disease

    Primary liver cancer is the fifth most common cancer worldwide. Hepatocellular carcinoma accounts for 85-90% of primary liver cancers. Distribution of hepatocellular carcinoma shows variations among geographic regions and ethnic groups. Males have higher liver cancer rates than females. Hepatocellular carcinoma occurs within an established background of chronic liver disease and cirrhosis (70-90%). Major causes (80%) of hepatocellular carcinoma are hepatitis B, C virus infection, and aflatoxin exposition. Its development is a multistep process. We have a growing understanding on the molecular pathogenesis. Genetic and epigenetic changes activate oncogenes, inhibit tumorsuppressor genes, which result in autonomous cell proliferation. The chromosomal instability caused by telomere dysfunction, the growth-retrained environment and the alterations of the micro- and macroenvironment help the expansion of the malignant cells. Understanding the molecular mechanisms could improve the screening of patients with chronic liver disease, or cirrhosis, and the prevention as well as treatment of hepatocellular carcinoma.

    Definitive chemoradiation (dCRT) is considered curative intent treatment for patients with inoperable or irresectable esophageal cancer. Acute toxicity data focussing on dCRT are lacking. A retrospective analysis of patients treated with dCRT consisting of 6 cycles of paclitaxel 50 mg/m2 and carboplatin AUC2 concomitant with radiotherapy (50.4 Gy/1.8Gy) from 2006 through 2011 at a single tertiary center was performed. Toxicity, hospital admissions and survival were analysed. 127 patients were treated with definitive chemoradiation. 33 patients were medically inoperable, 94 patients were irresectable, Despite of a significantly smaller tumor length in inoperable patients grade ≥3 toxicity was significantly recorded more often in the inoperable patients (44%) than in irresectable patients (20%) (p < 0.05) Hospital admission occurred more often in the inoperable patients (39%) than in the irresectable patients (22%) (p < 0.05) Median number of cycles of chemotherapy was five for inoperable patients (p = 0.01), while six cycles could be administered to patients with irresectable disease.

    To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

    Hepatocellular carcinoma (HCC) is the fifth most common and third most deadly type of cancer in the world. The majority of cases occur in Asia and Africa, resulting in most cases being diagnosed only at advanced stages of the disease when drug resistance is high. HCC typically follows damage to the liver such as cirrhosis, making radiation and chemotherapy a more challenging prospect. Surgery is also not a very viable option because less than one in four carcinomas can be completely removed. The limitations in these treatment modalities create the need for alternative therapeutic approaches.

    Full Text Available Liver cancer is the third most common cancer type and the second leading cause of deaths in men. Large population studies have demonstrated remarkable gender disparities in the incidence and the cumulative risk of liver cancer. A number of emerging risk factors regarding metabolic alterations associated with obesity, diabetes and dyslipidemia have been ascribed to the progression of non-alcoholic fatty liver diseases (NAFLD and ultimately liver cancer. The deregulation of fat metabolism derived from excessive insulin, glucose and lipid promotes cancer-causing inflammatory signaling and oxidative stress, which eventually triggers the uncontrolled hepatocellular proliferation. This review presents the current standing on the gender differences in body fat compositions and their mechanistic linkage with the development of NAFLD-related liver cancer, with an emphasis on genetic, epigenetic and microRNA control. The potential roles of sex hormones in instructing adipocyte metabolic programs may help unravel the mechanisms underlying gender dimorphism in liver cancer and identify the metabolic targets for disease management.

    Objective evaluation tools for assessing the effectiveness of stenting in palliative treatment of malignant biliary obstruction are not satisfactory. Effects of biliary stenting on liver volume change have never been studied. We aimed to use volumetry to analyze liver volume changes after endoscopic stenting in bile duct cancer according to the location and number of stents. Retrospective review. University hospital. Patients with a diagnosis of hilar or distal bile duct cancer and who underwent biliary metal stenting. ERCP with self-expandable metal stent placement. Liver volume change after biliary stenting and its comparison according to the location (hilar vs distal common bile duct) and number (hilar bilateral vs hilar unilateral). There were 60 patients; 31 were treated for hilar bile duct cancer (13 for bilateral stent and 18 for unilateral stent) and 29 for distal bile duct cancer. Overall mean follow-up duration was 11.7 ± 4.9 weeks. Liver volume increased 17.4 ± 24.1%. The rate of liver growth was rapid during the early period from 4 to 8 weeks. Stenting in hilar bile duct cancer tended to increase liver volume more than distal biliary stents (22.5% vs 11.9%, P = .091). In hilar bile duct cancer, unilateral and bilateral stents showed similar liver volume increases (20.1% and 25.8%, respectively; P = .512). Single center, retrospective. Biliary stenting markedly increased liver volume in both hilar and distal bile duct cancer. Our data suggest that liver volume assessment could be a useful tool for evaluating stent efficacy.

    Liver transplantation is the most effective treatment for selected patients with hepatocellular carcinoma. However, cancer recurrence, posttransplantation, remains to be the critical issue that affects the long-term outcome of hepatocellular carcinoma recipients. In addition to tumor biology itself, increasing evidence demonstrates that acute-phase liver graft injury is a result of hepatic ischemia reperfusion injury (which is an inevitable consequence during liver transplantation) and may promote cancer recurrence at late phase posttransplantation. The liver grafts from living donors, donors after cardiac death, and steatotic donors have been considered as promising sources of organs for liver transplantation and are associated with high incidence of liver graft injury. The acute-phase liver graft injury will trigger a series of inflammatory cascades, which may not only activate the cell signaling pathways regulating the tumor cell invasion and migration but also mobilize the circulating progenitor and immune cells to facilitate tumor recurrence and metastasis. The injured liver graft may also provide the favorable microenvironment for tumor cell growth, migration, and invasion through the disturbance of microcirculatory barrier function, induction of hypoxia and angiogenesis. This review aims to summarize the latest findings about the role and mechanisms of liver graft injury resulted from hepatic ischemia reperfusion injury on tumor recurrence posttransplantation, both in clinical and animal cohorts.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    The effect of traditional therapy is limited for liver cancer, gene therapy gets more and more recognition in recent years. Oncolysis virus is a kind of conditionally replicating virus, with special reproductivity in cancer cells, and then kills them. Gene agents are usually introduced into tumor tissue by intra-tumor and intra-arterial injection, and the technique of interventional therapy is able to satisfy the demand excellently. So, some breakthrough is expected in treating liver cancer by skillfully combining oncolysis virus and interventional technique. (authors)

    To diagnose and explore the serological diagnostic factors for liver metastasis in patients with breast cancer before symptoms occur. A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Liver metastasis was more likely to occur in patients with stage III cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase (GGT), alkaline phosphatase, lactate dehydrogenase (LDH), and carbohydrate antigen 153 (CA153) levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 µg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7%, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. The sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis

  18. Hazardous air pollutants and primary liver cancer in Texas.

    Directory of Open Access Journals (Sweden)

    Luca Cicalese

    Full Text Available The incidence of hepatocellular carcinoma (HCC, the most common primary liver cancer, is increasing in the US and tripled during the past two decades. The reasons for such phenomenon remain poorly understood. Texas is among continental states with the highest incidence of liver cancer with an annual increment of 5.7%. Established risk factors for HCC include Hepatitis B and C (HBV, HCV viral infection, alcohol, tobacco and suspected risk factors include obesity and diabetes. While distribution of these risk factors in the state of Texas is similar to the national data and homogeneous, the incidence of HCC in this state is exceptionally higher than the national average and appears to be dishomogeneous in various areas of the state suggesting that other non-recognized risk factors might play a role. No population-based studies are currently available investigating the effect of exposure to Hazardous Air Pollutants (HAPs as a contributing risk factor for liver cancer. Incidence rate of liver cancer in Texas by counties for the time period between 2002 and 2012 was obtained from the Texas Cancer Registry (TCR. Through Principal Component Analysis (PCA a subgroup of pollutants, explaining almost all the dataset variability, were identified and used to cluster Texas counties. The analysis generated 4 clusters showing liver cancer rate either higher or lower than national average in association with either high or low levels of HAPs emission in the environment. The study shows that the selected relevant HAPs, 10 among 253 analyzed, produce a significant correlation (P = 0.01-0.05 and some of these have been previously identified as carcinogens. An association between the increased production and consequent exposure to these HAPs and a higher presence of liver cancer in certain counties is suggested. This study provides a new insight on this complex multifactorial disease suggesting that environmental substances might play a role in the etiology of this

    Purpose: The standard treatment for patients with locally advanced inoperable non-small-cell lung cancer and good prognostic factors has become combined chemotherapy (ChT) and radiotherapy (RT). However, the sequencing of the two modalities, as well as fractionation of RT, has been controversial. The Radiation Therapy Oncology Group (RTOG) Study 92-04 was a randomized Phase II study designed to evaluate further the toxicity and efficacy of 2 different strategies of chemoradiation evaluated in 2 prior RTOG Phase II studies. Methods: Patients with Stage II or III medically inoperable or unresectable non-small-cell lung cancer, good performance status, and minimal weight loss were enrolled into a prospective randomized Phase II RTOG study. Arm 1 consisted of induction ChT (vinblastine 5 mg/m 2 i.v. bolus weekly for the first 5 weeks, and cisplatin, 100 mg/m 2 i.v. on Days 1 and 29) followed by concurrent ChT/RT (cisplatin 75 mg/m 2 i.v. on Days 50, 71, and 92) during thoracic radiotherapy (63 Gy in 34 fractions during 7 weeks starting on Day 50). Arm 2 was concurrent ChT and hyperfractionated RT starting on Day 1 with a total dose of 69.6 Gy in 58 fractions during 6 weeks, 1.2 Gy/fraction b.i.d. ChT consisted of cisplatin, 50 mg/m 2 i.v. on Days 1 and 8, and oral VP-16, 50 mg b.i.d. for 10 days only on the days of thoracic radiotherapy repeated on Day 29. Results: A total of 168 patients were entered between 1992 and 1994, and 163 patients were eligible for analysis. Eighty-one patients were treated in Arm 1 and 82 patients in Arm 2. Pretreatment characteristics, including age, gender, Karnofsky performance status, histologic features, and stage, were similar. The incidence of acute esophagitis was significantly higher among patients treated in Arm 2 than among those treated in Arm 1 (p<0.0001). The incidence of acute hematologic toxicity was significantly higher among patients treated in Arm 1 (p=0.01 for anemia and p=0.03 for other hematologic toxicities) than among

    Parasitic infection remains as a persistent public health problem and can be carcinogenic. Three helminth parasites, namely, Clonorchis sinensis (liver fluke) and Opisthorchis viverrini as well as Schistosoma haematobium (blood fluke), are classified as Group 1 carcinogens by the World Health Organization's International Agency for Research on Cancer (IARC Infection with liver flukes (Opisthorchis viverrini, Opisthorchis felineus and Clonorchis sinensis), World Health Organization, International Agency for Research on Cancer, 2011). Infection by these parasites is frequently asymptomatic and is thus rarely diagnosed at early exposure. Persistent infection can cause severe cancer complications. Until now, the cellular and molecular mechanisms linking fluke infections to cancer formation have yet to be defined, although many studies have focused on these mechanisms in recent years, and numerous findings were made in various aspects of parasite-associated cancers. Herein, we only introduce the fluke-induced cholangiocarcinoma (CCA) and bladder carcinoma and mainly focus on key findings in the last 5 years.

    2013-07-01

    Full Text Available We apply different polarization imaging techniques for cancerous liver tissues, and compare the relative contrasts for difference polarization imaging (DPI, degree of polarization imaging (DOPI and rotating linear polarization imaging (RLPI. Experimental results show that a number of polarization imaging parameters are capable of differentiating cancerous cells in isotropic liver tissues. To analyze the contrast mechanism of the cancer-sensitive polarization imaging parameters, we propose a scattering model containing two types of spherical scatterers and carry on Monte Carlo simulations based on this bi-component model. Both the experimental and Monte Carlo simulated results show that the RLPI technique can provide a good imaging contrast of cancerous tissues. The bi-component scattering model provides a useful tool to analyze the contrast mechanism of polarization imaging of cancerous tissues.

    New treatments for patients with liver cancer, the third most common cause of cancer-related death, are desperately needed. Hepatocellular carcinoma (HCC) is the most common type of liver cancer, and HCC tumors are particularly insensitive to chemotherapy. Surgery is the standard treatment for HCCs caught early, but only about a third of cases are identified at this stage. Antibody therapy offers a potential alternative for treating later-stage tumors.

    2007-01-01

    Background and Purpose: In an earlier phase II study, irradiation together with razoxane was shown to improve local control in recurrent rectal cancer. Therefore, the Austrian Society of Radiooncology (OeGRO) initiated a randomized controlled trial in 1992 to compare this combined treatment versus radiation therapy alone. Patients and Methods: Between 1992 and 1999, 36 patients with localized recurrences of rectal cancer were randomized to receive radiotherapy without (group A) or with razoxane (group B). The prognostic variables of the two groups were similar except for a longer median latency period from initial surgery to local recurrence in group A. High-energy photons with daily fractions between 170 and 200 cGy were used. The median total radiation dose was 60 Gy in each group. The patients in group B received a median razoxane dose of 9.6 g (range, 5-12 g). Main outcome measures were local control, overall survival, and toxicity. Results: The combined treatment with razoxane increased the local control rate compared to radiotherapy alone (39% vs. 8%; p = 0.05). The median survival time was not different between the groups (20 months each). No patient in arm A but four of 18 patients in arm B survived 5 years. Acute toxic effects were of moderate degree in both groups. There were no substantial differences as to late side effects. Conclusion: Radiotherapy together with razoxane is superior to radiation treatment alone in recurrent rectal cancer as far as local control is concerned. In some patients, long-term survival was achieved with razoxane and radiotherapy. (orig.)

    1996-01-01

    43 patients with stage III NSCLC (non-small cell lung cancer) entered a phase II study aimed at evaluating the toxicity and the activity of a combined modality programme including an accelerated split-course schedule (type B) of thoracic radiation therapy and a combination chemotherapy with vinorelbine and carboplatin. An objective response was achieved in 18/42 evaluable patients (5 complete and 13 partial responses), for an overall response rate of 43% (95% confidence interval, 28-58%). Four complete responses had a duration which exceeded 16 months. Treatment was well tolerated; grade III myelotoxicity occurred in only 14% of patients and treatment was delayed in only 2 cases because of grade 3 oesophagitis. Both tolerability and efficacy data suggest that this regimen holds promise for the treatment of patients with stage III NSCLC. (author)

    1982-02-01

    A total of 58 cases with inoperable advanced gastric carcinomas were treated by radiotherapy combined with tegafur, and the result was analyzed mainly from the aspects of life expectancies and some prognostic factors. Median survival time of all cases was 8.9 months. Actuarial survival rates at one, two, three, four and five years were 45%, 22%, 14%, 14% and 11% respectively. Cancer type, histologic type, tumor size and radiation effect on the primary lesion were chosen as the prognostic factors, and examined using median survival time as a parameter. Borrmann IV type cancer showed an unequivocally poor prognosis, whereas no significant prognostic differences were seen among other types. Poorly differentiated adenocarcinoma gave a poor prognosis. Radiation effect on the primary lesion seemed to have a positive correlation with prognosis, while life expectancies became shorter with the increase of tumor size. It seems, from the present study, that this combination therapy contributes a great deal to life prolongation of patients with inoperable advanced gastric carcinomas.

    2011-01-01

    Purpose: Little is known about the effects of cardiopulmonary function on the prognosis of concurrent chemoradiotherapy in patients with inoperable non-small-cell lung cancer (NSCLC). Methods and Materials: A retrospective analysis of the effects of tumor- and patient-related factors and parameters of cardiopulmonary function and heart morphology on the feasibility, toxicity, and prognosis was performed. Results: Cardiopulmonary function had no effect on the toxicity or feasibility of treatment; effects on survival were observed in the univariate analysis. Median survival varied as follows: cardiac function: 13.0 ± 1.6 months for left ventricular ejection fraction (LVEF) > 50% vs. 10.0 ± 1.9 months for LVEF ≤ 50% (p = 0.003); pulmonary function: 16.0 ± 0.6 months for no lung function deficits (vital capacity [VC] ≥ 60%, forced expiratory volume in 1 s ≥ 80%, and diffusing capacity of the lung for carbon monoxide (DLCO) ≥60%) vs. 14.0 ± 1.5 months for one or two function deficits vs. 8.0 ± 1.5 months for three lung function deficits (p = 0.001); T stage: 19.0 ± 3.1 months for rcT0/cT1/cT2 vs. 12.0 ± 0.8 months for cT3/cT4 (p = 0.039); and age: 11.0 ± 1.5 months for <60 years vs. 18.0 ± 2.5 months for 60-69 years vs. 12.0 ± 1.2 months for ≥70 years (p = 0.008). Prognostic factors identified in the multivariate analysis were LVEF ≤50% (p = 0.043; hazard ratio [HR], 1.74), reduced pulmonary function (p = 0.001; HR, 1.71 or 5.05) and T stage (p = 0.026; HR: 1.71). Conclusions: In addition to T-stage, cardiac and pulmonary function variables affected the survival of non-small-cell lung cancer patients after chemoradiotherapy.

    Full Text Available One of the most important types of liver cancer is hepatocellular carcinoma (HCC. HCC is the fifth most common cancer, and its correct diagnosis is very important. For the quick diagnosis of HCC, the use of nanoparticles is helpful. The major applications of nanoparticles are in medicine for organ imaging. Two methods of liver imaging are X-ray computed tomography (CT and magnetic resonance imaging (MRI. In this review, we attempt to summarize some of the contrast agents used in imaging such as superparamagnetic iron oxide nanoparticles (SPIONs and iron oxide nanoparticles (IONPs, various types of enhanced MRI for the liver, and nanoparticles like gold (AuNPs, which is used to develop novel CT imaging agents.

    Purpose: We report long-term disease control, survival, and toxicity for patients with locally advanced non-small cell lung cancer prospectively treated with concurrent proton therapy and chemotherapy on a nonrandomized case-only observational study. Methods: All patients received passive-scatter proton therapy, planned with 4D-CT–based simulation; all received proton therapy concurrent with weekly chemotherapy. Endpoints were local and distant control, disease-free survival (DFS), and overall survival (OS). Results: The 134 patients (21 stage II, 113 stage III; median age 69 years) had a median gross tumor volume (GTV) of 70 cm 3 (range, 5–753 cm 3 ); 77 patients (57%) received 74 Gy(RBE), and 57 (42%) received 60–72 Gy(RBE) (range, 60–74.1 Gy(RBE)). At a median follow-up time of 4.7 years, median OS times were 40.4 months (stage II) and 30.4 months (stage III). Five-year DFS rates were 17.3% (stage II) and 18.0% (stage III). OS, DFS, and local and distant control rates at 5 years did not differ by disease stage. Age and GTV were related to OS and DFS. Toxicity was tolerable, with 1 grade 4 esophagitis and 16 grade 3 events (2 pneumonitis, 6 esophagitis, 8 dermatitis). Conclusion: This report of outcomes after proton therapy for 134 patients indicated that this regimen produced excellent OS with tolerable toxicity

    The changes of cancer incidence upon immigration can be used as an estimator of environmental influence on cancer risk. We studied site-specific liver and biliary cancers in first-generation immigrants to Sweden with an aim to search for aetiological clues and to find evidence for indigenous incidence rates. We used the nation-wide Swedish Family-Cancer Database to calculate standardised incidence ratios (SIRs) in immigrants compared to native Swedes. A total of 1428 cancers were identified in immigrants whose median ages (years) at immigration were 27 for men and 26 for women and whose median diagnostic ages were 64 and 66, respectively. The highest SIRs of 6.7 for primary liver cancer were observed for men from East Asia and sub-Saharan Africa. Increased SIRs were recorded for male immigrants from previous Yugoslavia (1.78), Southern Europe (2.91), Turkey (2.15) and Asian Arab countries (2.89). For gallbladder cancer, only women from the Indian subcontinent (3.84) and Chile (2.34) had increased risk while some Northern European immigrants showed decreased risks. Primary liver cancer was increased in immigrants from endemic regions of hepatitis B virus infection but also from large regions lacking cancer incidence data, North Africa, Asian Arab countries, Turkey and previous Yugoslavia; these are probably intermediary risk regions for this infection. The consideration of these regions as risk areas would justify active diagnostic and vaccination programs. The increase in gallbladder cancer in Chileans and Indians suggests that some persistent damage was inflicted before emigration, characterisation of which will be a challenge for aetiological studies.

    Data on 93 autopsy cases (group A) of thorotrast-associated liver cancers were obtained from the Annual of Pathological Autopsy Cases in Japan from 1958 to 1979, and data on 78 autopsy cases (group B) of thorotrast-associated liver cancers were obtained from the Japanese literature from 1953 to 1980. Cholangiocarcinoma (CLC) constituted 58% of group A and 55% of group B. The curve of the cumulative numbers of patients with CLC versus year in group A was almost linear, showing an increasing risk per surviving patients with advancing time. Angiosarcoma (AGS) occurred in 25% of group A and 24% of group B. The number of patients with AGS increased significantly after 1969 in both groups. In group B, age and years after thorotrast injection of patients with AGS were statistically higher than those of patients with CLC. Hepatocellular carcinoma (HPC) accounted for 17 and 21% of groups A and B, respectively. When yearly distribution, age, and time after thorotrast injection of patients with HPC were correlated with those of patients with other liver cancers, the only statistically significant difference between patients with HPC and patients with CLC was in the years after thorotrast administration. Since 1977 multiple primary liver cancers including AGS developed in thorotrast-administered patients in both groups.

    Some techniques of the most recent interventional radiology are very useful for the treatment of metastatic liver cancer and changing the style of hepatic infusion chemotherapy. This report shows our latest results and methods of hepatic infusion chemotherapy for metastatic liver cancer. 1. For the catheter placement, a new catheterization route via the left subclavian artery into the hepatic artery was developed and performed in 132 cases. Superselective catheterization succeeded in 123 cases (93.2 %). This procedure is less invasive than laparotomy and less troublesome than other percutaneous routes. 2. For useful infusion system, an implantable injection port ''Reservoir'' was developed and it was used in 87 cases. This method makes arterial infusion chemotherapy easy, and imploves their quality of life. 3. To acquire adequate drug delivery, arterial redistribution by steel coils was done, and 109 arteries in 80 cases were occluded. This method is very useful to make multiple hepatic artery single and it is important to avoid gasroduodenal complications. 4. Now, using these techniques, the phase II study of 5FU, ADM, MMC combined hepatic infusion in patients with non-resectable metastatic liver cancer is done. Up to this time, such a phase study on arterial infusion chemotherapy was difficult because of technical problems, but these new techniques make it possible. In conclusion, these new methods change the style and conception of hepatic infusion, and these make much progress on the treatment of patients with metastatic liver cancer. (author)

    Nutritional disturbances such as ascites and hypoalbuminemia frequently arise after hepatectomy for liver cancer with liver cirrhosis. We examined the possibility of maintaining a favorable state of nutrition by outpatient administration of branched-chain amino acid (BCAA) granules. Forty-three patients who had gross liver cirrhosis complicated by liver cancer and underwent surgery up to May 2002 were given BCAA granules (n = 21, BCAA group) or no granules (n = 22, control group). 1) Background details such as age, sex, surgical technique, blood loss, and duration of surgery showed no significant differences. 2) Among objective findings, improvement of ascites and edema tended to occur sooner in the BCAA group, but without a significant difference. 3) Although serum albumin recovered its preoperative value 9 mo after surgery in the control group, only 6 mo was required for recovery in the BCAA group. Total protein showed similar changes, but neither group showed any difference in changes of aspartate aminotransferase, alanine transferase, or platelets. 4) One year postoperatively, the change from the preoperative indocyanine green retention rate at 15 min after intravenous administration tended to be worse in the control group, but not significantly so. 5) In the BCAA group, hyaluronic acid and type IV collagen 7S improved significantly sooner than in the control group. BCAA supplementation after hepatectomy promotes rapid improvement in protein metabolism and inhibits progression to liver cirrhosis. Administration of BCAA after hepatectomy is considered beneficial to a patient's nutritional state.

  15. Chronic alcohol drinking: Liver and pancreatic cancer?

    Science.gov (United States)

    Zakhari, Samir

    2015-09-01

    Cancer is a multifactorial disease that results from complex interactions of numerous risk factors - genetic and environmental - over time, eventually leading to the diseased phenotypes. Thus, while epidemiological studies can point to risk factors, they cannot determine cause and effect relationships, and are unable to give biological and clinical insights into carcinogenesis. The link between any risk factor and carcinogenesis needs to be validated in experimental models. This is particularly true in epidemiological studies on alcohol consumption and its consequences. While there is no doubt that heavy alcohol consumption has devastating health effects, the inconsistencies in alcohol-related epidemiological studies and cancer suffer from possible sources of the variability in outcomes, ranging from inaccuracy of self-report of consumption to the problem of correlating cancer that started decades earlier to current or recent alcohol consumption. To further study the interactions between alcohol and cancer, the use of "Molecular Pathological Epidemiology" (MPE) advocated by Ogino et al. for dissecting the interplay between etiological factors, cellular and molecular characteristics, and disease progression in cancer is appropriate. MPE does not consider cancer as a single entity, rather it integrates analyses of epidemiological studies with the macroenvironment and molecular and microenvironment. This approach allows investigating the relationships between potential etiological agents and cancer based on molecular signatures. More research is needed to fully elucidate the link between heavy alcohol consumption and pancreatic cancer, and to further investigate the roles of acetaldehyde and FAEEs in pancreatic carcinogenesis.

    Integration of Hepatitis B virus (HBV) into the human genome can cause genetic instability, leading to selective advantages for HBV-induced liver cancer. Despite the large number of studies for HBV integration into liver cancer, little is known about the mechanism of initial HBV integration events owing to the limitations of materials and detection methods. We conducted an HBV sequence capture, followed by ultra-deep sequencing, to screen for HBV integrations in 111 liver samples from human-hepatocyte chimeric mice with HBV infection and human clinical samples containing 42 paired samples from non-tumorous and tumorous liver tissues. The HBV infection model using chimeric mice verified the efficiency of our HBV-capture analysis and demonstrated that HBV integration could occur 23 to 49 days after HBV infection via microhomology-mediated end joining and predominantly in mitochondrial DNA. Overall HBV integration sites in clinical samples were significantly enriched in regions annotated as exhibiting open chromatin, a high level of gene expression, and early replication timing in liver cells. These data indicate that HBV integration in liver tissue was biased according to chromatin accessibility, with additional selection pressures in the gene promoters of tumor samples. Moreover, an integrative analysis using paired non-tumorous and tumorous samples and HBV-related transcriptional change revealed the involvement of TERT and MLL4 in clonal selection. We also found frequent and non-tumorous liver-specific HBV integrations in FN1 and HBV-FN1 fusion transcript. Extensive survey of HBV integrations facilitates and improves the understanding of the timing and biology of HBV integration during infection and HBV-related hepatocarcinogenesis.

    Colon cancer has been one of the major tumors in the world, both men and women; and it is constituted the third most commonly diagnosed tumor, with approximately 1.2 million of new cases per year. This cancer type is considered of great importance in Costa Rica and has occupied the fifth place. Age is the main risk factor, followed by environmental, diabetic and genetic factors. An IV colon cancer has been manifested with any T, with any N and metastases. Metastases from colon cancer to liver can be classified according to whether have been synchronous (20 to 25%) or metachronous (15 to 29%). In turn, they can be synchronous, resectable or unresectable or mechanical resectable or unresectable. The liver has been the most common site of metastases, and the status of this organ has been an important determinant of overall survival in patients with advanced disease. Half of the patients developed metastases during the course of the disease. Metastases has represented the leading cause of death from this tumor. With the advent of new surgical techniques, new anesthetic care, new chemotherapeutic and molecular agents, together with new radiofrequency modalities and ablative treatment, the approach of metastases from colon cancer to the liver has been shown to be decisive in the prolongation of survival of the patient, who in the past was considered a terminal patient [es

    There is accumulating evidence that cancer stem cells (CSCs) play an integral role in the initiation of hepatocarcinogenesis and the maintaining of tumor growth. Liver CSCs derived from hepatic stem/progenitor cells have the potential to differentiate into either hepatocytes or cholangiocytes. Primary liver cancers originating from CSCs constitute a heterogeneous histopathologic spectrum, including hepatocellular carcinoma, combined hepatocellular-cholangiocarcinoma, and intrahepatic cholangiocarcinoma with various radiologic manifestations. In this article, we reviewed the recent concepts of CSCs in the development of primary liver cancers, focusing on their pathological and radiological findings. Awareness of the pathological concepts and imaging findings of primary liver cancers with features of CSCs is critical for accurate diagnosis, prediction of outcome, and appropriate treatment options for patients.

    Purpose: To compare 2 stereotactic body radiation therapy (SBRT) schedules for medically inoperable early-stage lung cancer to determine which produces the lowest rate of grade ≥3 protocol-specified adverse events (psAEs) at 1 year. Methods and Materials: Patients with biopsy-proven peripheral (≥2 cm from the central bronchial tree) T1 or T2, N0 (clinically node negative by positron emission tomography), M0 tumors were eligible. Patients were randomized to receive either 34 Gy in 1 fraction (arm 1) or 48 Gy in 4 consecutive daily fractions (arm 2). Rigorous central accreditation and quality assurance confirmed treatment per protocol guidelines. This study was designed to detect a psAEs rate >17% at a 10% significance level (1-sided) and 90% power. Secondary endpoints included rates of primary tumor control (PC), overall survival (OS), and disease-free survival (DFS) at 1 year. Designating the better of the 2 regimens was based on prespecified rules of psAEs and PC for each arm. Results: Ninety-four patients were accrued between September 2009 and March 2011. The median follow-up time was 30.2 months. Of 84 analyzable patients, 39 were in arm 1 and 45 in arm 2. Patient and tumor characteristics were balanced between arms. Four (10.3%) patients on arm 1 (95% confidence interval [CI] 2.9%-24.2%) and 6 (13.3%) patients on arm 2 (95% CI 5.1%-26.8%) experienced psAEs. The 2-year OS rate was 61.3% (95% CI 44.2%-74.6%) for arm 1 patients and 77.7% (95% CI 62.5%-87.3%) for arm 2. The 2-year DFS was 56.4% (95% CI 39.6%-70.2%) for arm 1 and 71.1% (95% CI 55.5%-82.1%) for arm 2. The 1-year PC rate was 97.0% (95% CI 84.2%-99.9%) for arm 1 and 92.7% (95% CI 80.1%-98.5%) for arm 2. Conclusions: 34 Gy in 1 fraction met the prespecified criteria and, of the 2 schedules, warrants further clinical research.

    To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. Case report. Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year. Fundoscopic examination revealed parafoveal deposits bilaterally. Spectral domain optical coherence tomography exhibited hyperreflective deposits in all layers of the retina. She had a cumulative treatment dose of 292 g of tamoxifen, and the medication was subsequently stopped. Her vision remained stable 3 months after the cessation of tamoxifen. The development of tamoxifen retinopathy in the treatment of a desmoid tumor makes this case a rare entity, and this is the first reported case of these two concomitant conditions to our knowledge. With the use of long-term tamoxifen as a primary treatment, we recommend screening at regular intervals by an ophthalmologist as an integral part of treatment.

    Coffee intake is associated with reduced risk of liver cancer and chronic liver disease as reported in previous studies, including prospective ones conducted in Asian populations where hepatitis B viruses (HBVs) and hepatitis C viruses (HCVs) are the dominant risk factors. Yet, prospective studies in Western populations with lower HBV and HCV prevalence are sparse. Also, although preparation methods affect coffee constituents, it is unknown whether different methods affect disease associations. We evaluated the association of coffee intake with incident liver cancer and chronic liver disease mortality in 27,037 Finnish male smokers, aged 50-69, in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, who recorded their coffee consumption and were followed up to 24 years for incident liver cancer or chronic liver disease mortality. Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73-0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48-0.63; P-trendcoffee. These findings suggest that drinking coffee may have benefits for the liver, irrespective of whether coffee was boiled or filtered.

    Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer. A 66-year-old female consulted her physician for a mass she palpated on her left breast. The abdominal ultrasonography (USG) revealed a 44 x 28 mm mass in the medial segment of the left lobe of her liver suspicious of a metastasis. An USG-guided biopsy was performed and the histo-pathological examination revealed a "peripheral nerve sheath tumor". Positron emission tomography (PET-CT) revealed a pathologic FDG uptake in the lesion that was previously defined in the liver. The tumor resected from the liver was 5 x 4 x 3 cm, yellowish, soft, and capsulated tumor. Microscopic examination revealed that the mass consisted of bundles of spindle cells with hypercellular and hypocellular areas. In immunohistochemistry, there was a strong positive staining for S-100. The tumor was diagnosed as benign liver schwannoma. Schwannomas are benign, encapsulated neoplasms. Symptoms and signs vary depending on the anatomical site and the size of the neoplasm; however, most schwannomas present as an asymptomatic or painless mass. Recurrence is unusual, despite of an incomplete removal, and malignant transformation is exceedingly rare (Fig. 4, Ref. 8). Full Text (Free, PDF) www.bmj.sk.

    The patient, a 65-year-old male with far advanced gastric cancer of H3N4 (Stage 4), was assumed inoperable on admission and chemotherapy using CDDP, MMC and UFT(PMU) was carried out. As a result, the levels of AFP and CEA were reduced notably, and PR effects were recognized in liver and lymphnode metastatic lesion. Thus, 2 months later, reduction surgery was performed, during which primary lesion was resected and a reservoir tube for chemotherapy was placed in the common hepatic artery. Subsequently, the chemotherapy with Etoposide added to PMU(PMUE) was continued by utilization of a reservoir, so that liver metastasis decreased more than 90% from the maximum. However, metastasis lesions of left lobe of the liver had enlarged with reincrease of AFP and CEA since 6 months after the operation. A month later left lobectomy of the liver was performed. Residual metastases of the liver were then enlarged. PMUE with Ca antagonist was used with little effect then. The patient died of liver failure 15 months after initial admission.

    With multidisciplinary management of patients with effective chemotherapy that can downstage metastases, more patients with previously inoperable disease can benefit from surgery. Surgery in isolation may be approaching technical limits, but now is likely to help more patients because of success of complementary strategies, particularly newer chemotherapy and targeted therapy. Leaving behind disappearing metastases after chemotherapy, margin-positive resection, staged liver resection, and liver-first reversed management permit potentially curative surgery for patients previously unable to survive resection. Further, survival benefit from maximum debulking surgery, like ovarian cancer, for colorectal liver metastases is uncertain at present, but likely. Individualized multidisciplinary treatment planning using such strategies is essential.

    Liver cancer is the fifth most common cancer in men and the seventh for women. Usually because of late diagnosis, the prognosis for liver cancer remains poor, resulting in liver cancer being the third most common cause of death from cancer. While some countries have treatment guidelines, little is known or understood about the strategies needed for liver cancer control internationally. To explore leading liver cancer clinician's perceptions of the current public policy needs to control liver cancer internationally. Key informant interviews were conducted with a range of liver cancer clinicians involved in policy in eleven countries. Interviews were digitally recorded, transcribed verbatim, translated (where necessary), de-identified and analyzed by two researchers using a constant comparative method. Twenty in-depth semi-structured interviews were conducted in: Australia, China, France, Germany, Italy, Japan, Spain, South Korea, Taiwan, Turkey and the United States. Nine themes were identified and cluster into three groups: 1) Promoting prevention via early risk assessment, focusing on viral hepatitis and other lifestyle factors; 2) Increasing political, public and medical community awareness; and 3) Improving funding for screening, liver cancer surveillance and treatment. This study is an important step towards developing an evidence-based approach to assessing preparedness for implementing comprehensive liver cancer control strategies. Evaluation mechanisms to assess countries' performance on the needs described are needed. Future research will concentrate of understanding how these needs vary across countries and the optimal strategies to improve the diagnosis and prognosis of patients with liver cancer internationally.

    To evaluate the therapeutic efficacy of percutaneous cryotherapy for inoperable patients with malignant pulmonary nodules. We enrolled 14 patients (7 males, 7 females, average age 68.8 years) who had inoperable lung malignancy in this study from August 2006 through July 2009. We evaluated the therapeutic efficacy of cryotherapy for complete or incomplete ablation by follow up chest CT. Using Kaplan Meier statistical methods, we estimated the survival of patients who had undergone cryotherapy and we investigated post cryotherapy complications. Five of the 14 patients underwent complete ablation (35.7%), while 9 of 14 patients underwent incomplete ablation (64.3%). The change in mean size before procedure and at last follow up CT in the complete and incomplete ablation were as follows: 13.2 {+-} 7.6 mm {yields} 3.8 {+-} 2.7 mm, and 18.1 {+-} 6.2 mm {yields} 33.7 {+-} 17.9 mm, respectively. The median survival of patients in the complete and the incomplete groups were 51.5 months and 24 months, respectively. One patient developed a small pneumothorax, which resolved spontaneously. Two patients developed hemoptysis after the procedure, which was controlled within a day. Percutaneous cryotherapy may be an effective and safe therapeutic method for inoperable patients with malignant pulmonary nodules.

    To evaluate the therapeutic efficacy of percutaneous cryotherapy for inoperable patients with malignant pulmonary nodules. We enrolled 14 patients (7 males, 7 females, average age 68.8 years) who had inoperable lung malignancy in this study from August 2006 through July 2009. We evaluated the therapeutic efficacy of cryotherapy for complete or incomplete ablation by follow up chest CT. Using Kaplan Meier statistical methods, we estimated the survival of patients who had undergone cryotherapy and we investigated post cryotherapy complications. Five of the 14 patients underwent complete ablation (35.7%), while 9 of 14 patients underwent incomplete ablation (64.3%). The change in mean size before procedure and at last follow up CT in the complete and incomplete ablation were as follows: 13.2 ± 7.6 mm → 3.8 ± 2.7 mm, and 18.1 ± 6.2 mm → 33.7 ± 17.9 mm, respectively. The median survival of patients in the complete and the incomplete groups were 51.5 months and 24 months, respectively. One patient developed a small pneumothorax, which resolved spontaneously. Two patients developed hemoptysis after the procedure, which was controlled within a day.

    Full Text Available Accumulating evidence has indicated that oxidative stress (OS is associated with the development of hepatocellular carcinoma (HCC. However, the mechanisms remain largely unknown. Normally, OS occurs when the body receives any danger signal—from either an internal or external source—and further induces DNA oxidative damage and abnormal protein expression, placing the body into a state of vulnerability to the development of various diseases such as cancer. There are many factors involved in liver carcinogenesis, including hepatitis B virus (HBV and hepatitis C virus (HCV infection, alcohol abuse, and nonalcoholic fatty liver disease (NAFLD. The relationship between OS and HCC has recently been attracting increasing attention. Therefore, elucidation of the impact of OS on the development of liver carcinogenesis is very important for the prevention and treatment of liver cancer. This review focuses mainly on the relationship between OS and the development of HCC from the perspective of cellular and molecular mechanisms and the etiology and therapeutic targets of HCC.

    Full Text Available This study demonstrates a novel approach for the synthesis of silver nanoparticles (AgNPs against human liver cancer cell line (HepG2 using prodigiosin pigment isolated from Serratia marcescens. It further investigates the influence of various parameters such as initial pH, temperature, silver nitrate (AgNO 3 concentration, and prodigiosin concentration on stability and optical properties of synthesized prodigiosin AgNPs. Highly stable, spherical prodigiosin-conjugated AgNPs were synthesized with a mean diameter of 9.98 nm using a rapid one-step method. The cytotoxic activity investigated in the present study indicated that prodigiosin and prodigiosin-conjugated AgNPs possessed a strong cytotoxic potency against human liver cancer. The In silico molecular docking results of prodigiosin and prodigiosin-conjugated AgNPs are congruent with the In vitro studies and these AgNPs can be considered as good inhibitors of mitogen-activated protein kinase 1 (MEK kinases. The study opened the possibility of using prodigiosin-conjugated AgNPs to increase the efficiency of liver cancer treatment.

    To explore the effect of the interventional treatment for the angiogenesis and liver function in patients with liver cancer within short time, enzyme linked immunosorbent assay was used to determine the level of VEGF in plasma. The level of liver function was measured through automatic biochemistry analyzer. The results indicated that the level of VEGF in patients with liver cancer decreased after interventional treatment than that of before treatment (P<0.05). The level of total protein, albumin, alkaline phosphatase and total bile acid decreased after interventional treatment (P<0.05). The level of alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin and indirect bilirubin were increased than before (P<0.05). The interventional treatment inhibit the expression of the VEGF in the tumor tissue and limited the angiogenesis within short time, but to some extent may caused the injury of the hepatocytes and the synthetic and excremental function in patients with liver cancer.

    2014-04-10

    Liver cancer is the fifth most common cancer worldwide and the third most common cause of cancer mortality. Hepatocellular carcinoma (HCC) accounts for around 90% of primary liver cancers. Chronic infection with hepatitis B and hepatitis C viruses are two of most common causes of liver cancer. However, there are non-viral factors that are associated with liver cancer development. Numerous population studies have revealed strong links between obesity and the development of liver cancer. Obesity can alter hepatic pathology, metabolism and promote inflammation, leading to nonalcoholic fatty liver disease (NAFLD) and the progression to the more severe form, non-alcoholic steatohepatitis (NASH). NASH is characterised by prominent steatosis and inflammation, and can lead to HCC. Here, we discuss the role of obesity in inflammation and the principal signalling mechanisms involved in HCC formation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Signal transducer and activator of transcription 3 (STAT3) is an important transcription factor ubiquitously expressed in different cell types. STAT3 plays an essential role in cell survival, proliferation, and differentiation. Aberrantly hyper-activated STAT3 signaling in cancer cells and in the tumor microenvironment has been detected in a wide variety of human cancers and is considered an important factor for cancer initiation, development, and progression. However, the role of STAT3 activation in monocytes in the development of HCC has not been well understood. Immunohistochemical analysis of phosphorylated STAT3 was performed on tissue microarray from HCC patients. Using a co-culture system in vivo, HCC cell growth was determined by the MTT assay. In vivo experiments were conducted with mice given diethylinitrosamine (DEN), which induces HCC was used to investigate the role of STAT3 expression in monocytes on tumor growth. Real-time PCR was used to determine the expression of cell proliferation and cell arrest associated genes in the tumor and nontumor tissue from liver. Phosphorylated STAT3 was found in human hepatocellular carcinoma tissue samples and was expressed in tumor cells and also in monocytes. Phosphorylated STAT3 expression in monocyte was significantly correlated to advanced clinical stage of HCC and a poor prognosis. Using a co-culture system in vivo, monocytes promoted HCC cell growth via the IL-6/STAT3 signaling pathway. The STAT3 inhibitor, NSC 74859, significantly suppressed tumor growth in vivo in mice with diethylinitrosamine (DEN)-induced HCC. In this animal model, blockade of STAT3 with NSC 74859 induced tumor cell apoptosis, while inhibiting both tumor cells and monocytes proliferation. Furthermore, NSC 74859 treatment suppressed cancer associated inflammation in DEN-induce HCC. Our data suggest constitutively activated STAT3 monocytes promote liver tumorigenesis in clinical patients and animal experiments. Thus, STAT3 in tumor

    Colonic mucosal defects might be a route for bacterial invasion into the portal system, with subsequent hematogenous spread to the liver. We retrospectively investigated the results of colonoscopy and the clinical characteristics of patients with pyogenic liver abscess of colonic origin. A total of 230 consecutive patients with pyogenic liver abscess were reviewed between 2003 and 2010. The 230 patients were categorized into three groups (pancreatobiliary [n = 135], cryptogenic [n = 81], and others [n = 14]). Of the 81 cryptogenic patients, 37 (45.7%) underwent colonoscopy. Colonic lesions with mucosal defects were considered colonic causes of abscess. In the 37 colonoscopic investigations, colon cancer was found in six patients (16.2%), laterally-spreading tumor (LST) in two patients (5.4%), multiple colon ulcers in one patient (2.7%), colon polyps in 17 patients (45.9%), and diverticula in four patients (10.8%). Nine (11%) of 81 cryptogenic abscesses were therefore reclassified as being of colonic origin (colon cancer = 6, LST = 2, ulcer = 1). Three cases were stage III colon cancer, and the others were stage I. Two LST were high-grade dysplasia. The percentage of patients with Klebsiella pneumoniae (K. pneumoniae) and diabetes mellitus (DM) of colonic origin was 66.7%, which was significantly higher than the 8.6% for other causes (P colonic cause. Colonoscopy should be considered for the detection of hidden colonic malignant lesions in patients with cryptogenic pyogenic liver abscess, especially for patients with K. pneumoniae and DM. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    To prospectively evaluate the efficacy and safety of selective internal radiation (SIR) spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77). Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%), with the median duration of response being 8.3 months (range 2–18) and median time to progression of 5.3 mths. Response rates were lower (21%) and progression free survival shorter (3.9 mths) in patients that had received all standard chemotherapy options (n = 14). No responses were seen in patients with a poor performance status (n = 3) or extrahepatic disease (n = 6). Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond

    Full Text Available Background: The incidence of liver cancer has been increasing in Canada over the past decade, as has cyanobacterial contamination of Canadian freshwater lakes and drinking water sources. Cyanotoxins released by cyanobacteria have been implicated in the pathogenesis of liver cancer. Objective: To determine whether a geographic association exists between liver cancer and surrogate markers of cyanobacterial contamination of freshwater lakes in Canada. Methods: A negative binomial regression model was employed based on previously identified risk factors for liver cancer. Results: No association existed between the geographic distribution of liver cancer and surrogate markers of cyanobacterial contamination. As predicted, significant associations existed in areas with a high prevalence of hepatitis B virus infection, large immigrant populations and urban residences. Discussion and Conclusions: The results of this study suggest that cyanobacterial contamination of freshwater lakes does not play an important role in the increasing incidence of liver cancer in Canada.

    Percutaneous destruction of cancer cells using a radiofrequency energy source has become an accepted part of the modern armamentarium for managing malignancies. Radiofrequency ablation (RFA) is a relatively novel procedure for treating recurrent and metastatic tumors. It is used for debulking tumors and as adjuvant therapy for palliative care apart from its role as a pain management tool. Its use in the third world countries is limited by various factors such as cost and expertise. In the remotest parts of India, where economic development has been slow, abject poverty with poor health care facilities advanced malignancies present a challenge to health care providers. We undertook this study to assess the safety of the percutaneous RFA tumor ablation as a therapeutic or palliative measure in patients where surgery was not possible. We observed that RFA may be an effective, alternative therapeutic modality for some inoperable tumors where other therapeutic modalities cannot be considered. Palliative and therapeutic image-guided RFAs of tumors may be the only treatment option in patients who are inoperable for a variety of reasons. To assess the safety and complications of RFA in such a patient population is important before embarking upon any interventions given their physically, mentally, and socially compromised status in a country such as India. To assess the safety of percutaneous image-guided radiofrequency tumor ablation and to note the various immediate and early complications of the intervention. This was a prospective, observational study conducted in Tata Main Hospital, Jamshedpur, Jharkhand, India. After approval by the Hospital Approval Committee all patients who consented for percutaneous RFA of their tumor admitted in the hospital were included after taking fully informed consent from patient/close relative keeping the following criteria in view. Patients who were likely to derive a direct benefit in the survival or as a palliative measure for relief

    To analyze the disease burden of liver cancer in the Chinese population in 1990 and 2013. Data from Global Burden of Diseases 2013 (GBD2013) was used to analyze the disease burden of liver cancer in China. The main outcome measurements would include mortality and disability-adjusted life years (DALY). Again, GBD global standard population in 2013 was used as the reference population to calculate the age-standardized rate. Related changes on percentage from 1990 to 2013 were calculated to analyze the changing patterns of disease burden for liver cancer in China. In 2013, a total of 358 100 people died of liver cancer, with the crude death rate as 25.85/100 000, in China. Number of deaths due to liver cancer secondary to hepatitis B was 163 600 (accounting for 45.69%). Number of deaths due to liver cancer secondary to hepatitis C was 134 200 (accounting for 37.48%) with DALY due to liver cancer appeared as 40.80 million person years. In 2013, the leading causes of DALY related to liver cancer was liver cancer secondary to hepatitis B, followed by liver cancer secondary to hepatitis C, liver cancer secondary to alcohol use, other liver cancers, with related DALYs as 4 652.0, 3 394.3, 964.3 and 592.1 thousands person years, respectively. The disease burdens of liver cancer secondary to various kinds of liver cancer were significantly higher in males than in females. Compared with 1990, the standardized mortality of liver cancer reduced by 25.00%, the DALY attributable to liver cancer increased by 16.95% and the standardized DALY rate attributable to liver cancer reduced by 33.47%. The burden of liver cancer secondary to hepatitis C became more serious and the standardized death rate increased by 106.18%, together with the standardized DALY rate increased by 91.68% in the past 23 years. Disease burden of liver cancer among young adults and the elderly were most serious. When comparing with the data in 1990, the standardized DALY rate showed declining trend in all the

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; alpha-fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was reevaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

    In seven primary liver cancers (HCC 5, CCC 1, mixed 1), MR images (0.35 Tesla superconducting) were compared with macroscopic appearances, and relaxation times (T 1 and T 2 ) with microscopic characteristics. MRI was able to reveal the gross appearance of five nodular lesions, but did not reveal one diffuse HCC and one nodular HCC with marked extracapsular extension. T 2 -weighted SE images could not demonstrate fibrous capsules around the tumor in four nodular HCCs. The T 1 and T 2 values of the tumors were longer than those of the surrounding liver parenchyma, and the T 1 elongation corresponded roughly to the degree of necrosis and fibrosis within the tumors.

    Full Text Available Abstract A 31-year-old man with sigmoid colon cancer with concomitant simultaneous multiple liver metastases had received FOLFIRI (leucovorin, fluorouracil and irinotecan and FOLFOX6 (leucovorin, fluorouracil and oxaliplatin after an ordinary sigmoidectomy. However, his serum carcinoembryonic antigen (CEA level increased rapidly during the fifteen months after the operation while he was on FOLFOX6. Abdominal computed tomography revealed expanding multiple liver tumors. As the third line chemotherapy, a combination therapy of cetuximab with irinotecan was given, which markedly reduced his levels of serum CEA, and the size and number of liver tumors. He underwent lateral segmentectomy of the liver and microwave coagulation of the liver metastases in the remnant liver. Thereafter, a good quality of life with tumor dormancy was obtained for 6 months. However, his serum CEA started to rise again in the absence of liver tumors. Therefore, FOLFOX6 with bevacizumab was chosen as the fourth line chemotherapy, and the serum CEA was reduced with tumor dormancy. A good quality of life was obtained again at 3 years after the first surgery. This report indicates the effectiveness of sandwiched liver surgery with the molecular targeting drugs cetuximab and bevacizumab on multiple liver metastases of colon cancer, and suggests the possibility of a regimen consisting of bevacizumab following cetuximab.

    Full Text Available Malignant pheochromocytoma (PCC is a rare condition. Although the liver is the second most frequent site of metastasis in malignant PCC, no definite treatments have been established. Herein, we report a case of liver metastasis of PCC that was successfully treated by transcatheter arterial chemoembolization (TACE. A 69-year-old man was admitted to the Department of Gastroenterology for evaluation of an incidental hepatic mass in August 2013. He had undergone right adrenalectomy in May 2005 and PCC had been confirmed on the basis of histopathological findings. Liver biopsy was performed, and metastatic PCC was diagnosed. The lesion appeared inoperable because of invasion of the portal vein and metastases in the lymph nodes along the hepatoduodenal ligament. Thus, TACE was performed instead. After TACE, symptoms including dizziness and cold sweating improved, and the patient's serum catecholamine levels decreased. On the basis of this case, we believe that TACE may be a useful treatment for liver metastasis in malignant PCC.

    The accuracy of liverscanning alkaline phosphatase and 5'-nucleotidase in the detection of the hepatic metastases was studied in short interval autopsy material of 243 cancer patients. The highest percentage of correct diagnosis was by 5'-nucleotidase, alkaline phosphatase was the second, and scanning third. The overall accuracy of liver scan was 68 per cent. It was the better the shorter the time interval between scanning and autopsy. The higher percentage of incorrect diagnoses of the scan was related to a larger number of false positives, the causes of which were to be verified only in half of the cases. (orig.) [de

    In this paper, automated extraction of metastatic liver cancer regions from abdominal contrast X-ray CT images is investigated. Because even in Japan, cases of metastatic liver cancers are increased due to recent Europeanization and/or Americanization of Japanese eating habits, development of a system for computer aided diagnosis of them is strongly expected. Our automated extraction procedure consists of following four steps; liver region extraction, density transformation for enhancement of cancer regions, segmentation for obtaining candidate cancer regions, and reduction of false positives by shape feature. Parameter values used in each step of the procedure are decided based on density and shape features of typical metastatic liver cancers. In experiments using practical 20 cases of metastatic liver tumors, it is shown that 56% of true cancers can be detected successfully from CT images by the proposed procedure. (author)

    Purpose: To measure the intrabreath-hold liver motion and the intrafraction and interfraction reproducibility of liver position relative to vertebral bodies using an active breathing coordinator (ABC) in patients with unresectable liver cancer treated with hypofractionated stereotactic body radiation therapy (SBRT). Methods: Tolerability of ABC and organ motion during ABC was assessed using kV fluoroscopy in 34 patients. For patients treated with ABC, repeat breath-hold CT scans in the ABC breath-hold position were acquired at simulation to estimate the volumetric intrafraction reproducibility of the liver relative to the vertebral bodies. In addition, preceding each radiation therapy fraction, with the liver immobilized using ABC, repeat anteroposterior (AP) megavoltage verification images were obtained. Off-line alignments were completed to determine intrafraction reproducibility (from repeat images obtained before one treatment) and interfraction reproducibility (from comparisons of the final image for each fraction with the AP) of diaphragm position relative to vertebral bodies. For each image set, the vertebral bodies were aligned, and the resultant craniocaudal (CC) offset in diaphragm position was measured. Liver position during ABC was also evaluated from kV fluoroscopy acquired at the time of simulation, kV fluoroscopy at the time of treatment, and from MV beam's-eye view movie loops acquired during treatment. Results: Twenty-one of 34 patients were screened to be suitable for ABC. The average free breathing range of these patients was 13 mm (range, 5-1 mm). Fluoroscopy revealed that the average maximal diaphragm motion during ABC breath-hold was 1.4 mm (range, 0-3.4 mm). The MV treatment movie loops confirmed diaphragm stability during treatment. For a measure of intrafraction reproducibility, an analysis of 36 repeat ABC computed tomography (CT) scans in 14 patients was conducted. The average mean difference in the liver surface position was -0.9 mm, -0

    Nucleoskeleton maintains the framework of a cell nucleus that is required for a variety of nuclear functions. However, the nature of nucleoskeleton structure has not been yet clearly elucidated due to microscopy visualization limitations. Plectin, a nuclear pore-permeable component of cytoskeleton, exhibits a role of cross-linking between cytoplasmic intermediate filaments and nuclear lamins. Presumably, plectin is also a part of nucleoskeleton. Previously, we demonstrated that pleomorphism of hepatoma cells is the consequence of cytoskeletal changes mediated by plectin deficiency. In this study, we applied a variety of technologies to detect the cytoskeletons in liver cells. The images of confocal microscopy did not show the existence of plectin, intermediate filaments, microfilaments and microtubules in hepatic nuclei. However, in the isolated nuclear preparation, immunohistochemical staining revealed positive results for plectin and cytoskeletal proteins that may contribute to the contamination derived from cytoplasmic residues. Therefore, confocal microscopy provides a simple and effective technology to observe the framework of nucleoskeleton. Accordingly, we verified that cytoskeletons are not found in hepatic cell nuclei. Furthermore, the siRNA-mediated knockdown of plectin in liver cells leads to collapsed cytoskeleton, cell transformation and pleomorphic nuclei. Plectin and cytoskeletons were not detected in the nuclei of liver cells compared to the results of confocal microscopy. Despite the absence of nuclear plectin and cytoskeletal filaments, the evidence provided support that nuclear pleomorphism of cancer cells is correlated with the cytoplasmic disorganization of cytoskeleton.

    Full Text Available Abstract Background Liver cancer is the fifth most common cancer in men and the seventh for women. Usually because of late diagnosis, the prognosis for liver cancer remains poor, resulting in liver cancer being the third most common cause of death from cancer. While some countries have treatment guidelines, little is known or understood about the strategies needed for liver cancer control internationally. Objective To explore leading liver cancer clinician's perceptions of the current public policy needs to control liver cancer internationally. Methods Key informant interviews were conducted with a range of liver cancer clinicians involved in policy in eleven countries. Interviews were digitally recorded, transcribed verbatim, translated (where necessary, de-identified and analyzed by two researchers using a constant comparative method. Results Twenty in-depth semi-structured interviews were conducted in: Australia, China, France, Germany, Italy, Japan, Spain, South Korea, Taiwan, Turkey and the United States. Nine themes were identified and cluster into three groups: 1 Promoting prevention via early risk assessment, focusing on viral hepatitis and other lifestyle factors; 2 Increasing political, public and medical community awareness; and 3 Improving funding for screening, liver cancer surveillance and treatment. Conclusion This study is an important step towards developing an evidence-based approach to assessing preparedness for implementing comprehensive liver cancer control strategies. Evaluation mechanisms to assess countries' performance on the needs described are needed. Future research will concentrate of understanding how these needs vary across countries and the optimal strategies to improve the diagnosis and prognosis of patients with liver cancer internationally.

    2008-01-01

    Background and Aims: In a retrospective study using stereotactic body radiotherapy (SBRT) in medically inoperable patients with stage I NSCLC we previously reported a local control rate of 88% utilizing a median dose of 15 Gy x 3. This report records the toxicity encountered in a prospective phase II trial, and its relation to coexisting chronic obstructive pulmonary disease (COPD) and cardio vascular disease (CVD). Material and methods: Sixty patients were entered in the study between August 2003 and September 2005. Fifty-seven patients (T1 65%, T2 35%) with a median age of 75 years (59-87 years) were evaluable. The baseline mean FEV1% was 64% and median Karnofsky index was 80. A total dose of 45 Gy was delivered in three fractions at the 67% isodose of the PTV. Clinical, pulmonary and radiological evaluations were made at 6 weeks, 3, 6, 9, 12, 18, and 36 months post-SBRT. Toxicity was graded according to CTC v2.0 and performance status was graded according to the Karnofsky scale. Results: At a median follow-up of 23 months, 2 patients had relapsed locally. No grade 4 or 5 toxicity was reported. Grade 3 toxicity was seen in 12 patients (21%). There was no significant decline of FEV1% during follow-up. Low grade pneumonitis developed to the same extent in the CVD 3/17 (18%) and COPD 7/40 (18%) groups. The incidence of fibrosis was 9/17 (53%) and pleural effusions was 8/17 (47%) in the CVD group compared with 13/40 (33%) and 5/40 (13%) in the COPD group. Conclusion: SBRT for stage I NSCLC patients who are medically inoperable because of COPD and CVD results in a favourable local control rate with a low incidence of grade 3 and no grade 4 or 5 toxicity

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is currently the fifth most common malignancy in men and the eighth in women worldwide. According to the latest European Union countries’ statistics the incidence of HC cancer is about 8,29 per 100000 accidents, cholangiocellular (CC cancer – 0,9-1,3 per 100 thousand of population per year[10,14]. Hepatitis B virus (HBV is the major etiologic factor for the development of HCC [18]. People chronically infected with HBV are 20 times more likely to develop liver cancer than uninfected people [1,22,28]. Many studies have shown the association between Hepatitis B virus (HBV and hepatitis C virus (HCV infections and the development of cholangiocarcinoma (CCA [4,6,9,11,12]. At the same time, the expression features of HBsAg, HBcAg in HCC and CCA have not been studied clearly yet. Aim of investigation: to study the expression features of hepatitis B antigens in tumor tissue from patients with hepatocellular carcinoma and cholangiocarcinoma. Materials and methods. The complex pathomorphological research was performed using liver biopsies of 87 patients aged from 33 up to 83 years, where 50 (57,47% of them had HCC carcinoma and 37 (42,53% had cholangiocellular cancer. 15 patients among examined 87 ones were ill with chronic viral hepatitis (11 were ill with HCV, 3 – HBV B, 1 – HBV + HCV before, 72 cancer patients, corresponding to the clinical data, never had this one in their past medical history. The localization of hepatitis B surface antigen (HBsAg and core antigen (HBcAg was investigated by an indirect immunoperoxidase method in formalin-fixed, paraffin-embedded liver specimens obtained from 50 (57,47% patients with hepatocellular carcinoma and 37 (42,53% patients with cholangiocarcinoma. using antibodies Rb a-Hu Primary Hepatitis B Virus Core Antigen (HBcAg and Mo a-Hu Primary Hepatitis B Virus Surface Antigen (HBsAg, Сlone 3E7, and visualization system DAKO EnVision+ with diaminobenzidine.

    Full Text Available Tumor metastasis is a complicated process with multiple steps, and liver metastasis is the most common metastatic mode of colorectal cancer. Deep understanding and study of metastatic mechanism helps to find solutions for colorectal cancer liver metastasis. Recent studies have shown that microRNA are involved in tumor metastasis and recurrence, and studies on microRNA associated with colorectal cancer liver metastasis can provide new thoughts for the development and progression, diagnosis and treatment, and prognosis of the disease. This article summarizes the research advances in microRNA associated with colorectal cancer liver metastasis and reviews the biological function and molecular mechanism of microRNA, which suggests that microRNA have a vital significance in the field of tumor metastasis, especially colorectal cancer liver metastasis.

    Purpose. To analyze the factors associated with favorable survival in patients with inoperable colorectal lung metastases treated with percutaneous image-guided radiofrequency ablation. Methods. Between 2002 and 2011, a total of 398 metastases were ablated in 122 patients (87 male, median age 68 years, range 29-90 years) at 256 procedures. Percutaneous CT-guided cool-tip radiofrequency ablation was performed under sedation/general anesthesia. Maximum tumor size, number of tumors ablated, number of procedures, concurrent/prior liver ablation, previous liver or lung resection, systemic chemotherapy, disease-free interval from primary resection to lung metastasis, and survival from first ablation were recorded prospectively. Kaplan-Meier analysis was performed, and factors were compared by log rank test. Results. The initial number of metastases ablated was 2.3 (range 1-8); the total number was 3.3 (range 1-15). The maximum tumor diameter was 1.7 (range 0.5-4) cm, and the number of procedures was 2 (range 1-10). The major complication rate was 3.9 %. Overall median and 3-year survival rate were 41 months and 57 %. Survival was better in patients with smaller tumors-a median of 51 months, with 3-year survival of 64 % for tumors 2 cm or smaller versus 31 months and 44 % for tumors 2.1-4 cm (p = 0.08). The number of metastases ablated and whether the tumors were unilateral or bilateral did not affect survival. The presence of treated liver metastases, systemic chemotherapy, or prior lung resection did not affect survival. Conclusion. Three-year survival of 57 % in patients with inoperable colorectal lung metastases is better than would be expected with chemotherapy alone. Patients with inoperable but small-volume colorectal lung metastases should be referred for ablation.

    Phenobarbital is not genotoxic, but has been related to promotion of liver cancer (as well as inhibition) in rodents. In October 2012, we carried out a systematic literature search in the Medline database and searched reference lists of retrieved publications. We identified 15 relevant papers. Epidemiological data on epileptics/anticonvulsant use and liver cancer were retrieved from eight reports from seven cohort (record linkage) studies of epileptics, and data on phenobarbital use from a pharmacy-based record linkage investigation of patients treated with phenobarbital (three reports), plus a case-control study nested in one of the cohort studies and including information on phenobarbital use. Of the studies of cancer in epileptics, two showed no excess risk of liver cancer. A long-term (1933-1984) Danish cohort study of epileptics found relative risks (RRs) of 4.7 [95% confidence interval (CI) 3.2-6.8] of liver cancer and of 2.2 (95% CI 1.2-3.5) of biliary tract cancers. Such apparent excess risks could, however, be largely or completely attributed to thorotrast, a contrast medium used in the past in epileptic patients for cerebral angiography. A Finnish cohort study of epileptics obtained an RR of 1.7 (95% CI 1.2-2.4). Such an apparent excess risk, however, was not related to phenobarbital or to any specific anticonvulsant drug. The long-term follow-up of two UK cohorts found some excess risk of liver cancer among severe, but not among mild, epileptics. Some excess risk of liver cancer was also found in cohort studies of patients hospitalized for epilepsy in Sweden and Taiwan, in the absence, however, of association with any specific drugs. A UK General Practice database, comparing epileptics treated with valproate with unexposed ones, found a very low incidence of liver cancer. Of the studies of cancer in patients treated with phenobarbital, a large US pharmacy-based cohort investigation showed no excess risk of liver cancer. In a case-control study, nested in

    Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396), comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04). Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

    The leading cause of death among cancer patients is tumor metastasis. Tumor-derived exosomes are emerging as mediators of metastasis. In the present study, we demonstrated that exosomes play a pivotal role in the metastatic progression of colorectal cancer. First, a nude mouse model of colorectal cancer liver metastasis was established and characterized. Then, we demonstrated that exosomes from a highly liver metastatic colorectal cancer cell line (HT-29) could significantly increase the metastatic tumor burden and distribution in the mouse liver of Caco-2 colorectal cancer cells, which ordinarily exhibit poor liver metastatic potential. We further investigated the mechanisms by which HT-29-derived-exosomes influence the liver metastasis of colorectal cancer and found that mice treated with HT-29-derived exosomes had a relatively higher level of CXCR4 in the metastatic microenvironment, indicating that exosomes may promote colorectal cancer metastasis by recruiting CXCR4-expressing stromal cells to develop a permissive metastatic microenvironment. Finally, the migration of Caco-2 cells was significantly increased following treatment with HT-29-derived exosomes in vitro, further supporting a role for exosomes in modulating colorectal tumor-derived liver metastasis. The data from the present study may facilitate further translational medicine research into the prevention and treatment of colorectal cancer liver metastasis.

    During the past decade, research on primary liver cancers has particularly highlighted the uncommon plasticity of differentiated parenchymal liver cells (that is, hepatocytes and cholangiocytes (also known as biliary epithelial cells)), the role of liver progenitor cells in malignant transformation......, the importance of the tumour microenvironment and the molecular complexity of liver tumours. Whereas other reviews have focused on the landscape of genetic alterations that promote development and progression of primary liver cancers and the role of the tumour microenvironment, the crucial importance...... of the cellular origin of liver cancer has been much less explored. Therefore, in this Review, we emphasize the importance and complexity of the cellular origin in tumour initiation and progression, and attempt to integrate this aspect with recent discoveries in tumour genomics and the contribution...

    Oral administration of red ginseng extracts (1% in diet for 40 weeks) resulted in the significant suppression of spontaneous liver tumor formation in C3H/He male mice. Average number of tumors per mouse in control group was 1.06, while that in red ginseng extracts-treated group was 0.33 (p<0.05). Incidence of liver tumor development was also lower in red ginseng extracts-treated group, although the difference from control group was not statistically significant. Anti-carcinogenic activity of white ginseng extracts, besides red ginseng extracts, was also investigated. In the present study, the administration of white ginseng extracts was proven to suppress tumor promoter-induced phenomena in vitro and in vivo. It is of interest that oral administration of the extracts of Ren-Shen-Yang- Rong-Tang, a white ginseng-containing Chinese medicinal prescription, resulted in the suppression of skin tumor promotion by 12-o-tetradecanoylphorbol-13-acetate in 7,12-dimethylbenz[a]anthracene-initiated CD-1 mice. These results suggest the usefulness of ginseng in the field of cancer prevention. PMID:11748379

    The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti-VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy ± bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability. It is therefore very important to discuss the treatments with a multidisciplinary team, including an experienced surgeon, an interventional radiologist and an oncologist. On the other hand, some patients could benefit in terms of quality of life and decreased toxicity from less intense treatment when resection is not an objective. First-line monotherapy or a maintenance strategy with biotherapy and/or cytotoxics could be discussed with these patients, and treatment holidays should be considered in selected patients. Finally, in patients with secondary resection of liver metastases, specificity should be considered in choosing the best adjuvant treatment, such as response to preoperative treatment and individual risk of relapse, which many in some cases justify intensification with hepatic arterial infusion in an adjuvant setting.

    Intrahepatic cholangiocarcinoma (ICC) is an aggressive cancer associated with the bile ducts within the liver. These tumors are characterized by frequent gain-of-function mutations in the isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) genes—that are also common in subsets of neural, haematopoietic and bone tumors, but rare or absent in the other types of gastrointestinal malignancy. Mutant IDH acts through a novel mechanism of oncogenesis, producing high levels of the metabolite 2-hydroxyglutarate, which interferes with the function of α-ketoglutarate-dependent enzymes that regulate diverse cellular processes including histone demethylation and DNA modification. Recently, we used in vitro stem cell systems and genetically engineered mouse models (GEMMs) to demonstrate that mutant IDH promotes ICC formation by blocking hepatocyte differentiation and increasing pools of hepatic progenitors that are susceptible to additional oncogenic hits leading to ICC. We found that silencing of HNF4A—encoding a master transcriptional regulator of hepatocyte identity and quiescence—was critical to mutant IDH-mediated inhibition of liver differentiation. In line with these findings, human ICC with IDH mutations are characterized by a hepatic progenitor cell transcriptional signature suggesting that they are a distinct ICC subtype as compared to IDH wild type tumors. The role of mutant IDH in controlling hepatic differentiation state suggests the potential of newly developed inhibitors of the mutant enzyme as a form of differentiation therapy in a solid tumor.

    Hepatocarcinogenesis is a complex multistep process in which many different molecular pathways have been implicated. Hepatocellular carcinoma (HCC) is refractory to conventional chemotherapeutic agents, and the new targeted therapies are meeting with limited success. Interreceptor crosstalk and the positive feedback between different signaling systems are emerging as mechanisms of targeted therapy resistance. The identification of such interactions is therefore of particular relevance to improve therapeutic efficacy. Among the different signaling pathways activated in hepatocarcinogenesis the epidermal growth factor receptor (EGFR) system plays a prominent role, being recognized as a “signaling hub” where different extracellular growth and survival signals converge. EGFR can be transactivated in response to multiple heterologous ligands through the physical interaction with multiple receptors, the activity of intracellular kinases or the shedding of EGFR-ligands. In this article we review the crosstalk between the EGFR and other signaling pathways that could be relevant to liver cancer development and treatment

    A revised Group Method of Data Handling (GMDH)-type neural network algorithm using artificial intelligence technology for medical image diagnosis is proposed and is applied to medical image diagnosis of liver cancer. In this algorithm, the knowledge base for medical image diagnosis are used for organizing the neural network architecture for medical image diagnosis. Furthermore, the revised GMDH-type neural network algorithm has a feedback loop and can identify the characteristics of the medical images accurately using feedback loop calculations. The optimum neural network architecture fitting the complexity of the medical images is automatically organized so as to minimize the prediction error criterion defined as Prediction Sum of Squares (PSS). It is shown that the revised GMDH-type neural network can be easily applied to the medical image diagnosis. (author)

    Western-style high fat, high sugar diets are associated with non-alcoholic fatty liver disease (NAFLD) and increased liver cancer risk. Sulforaphane from broccoli may protect against these. Previously we initiated broccoli feeding to mice prior to exposure to the hepatocarcinogen diethylnitrosamine (DEN), and saw protection against NAFLD and liver cancer. Here we administered DEN to unweaned mice, initiating broccoli feeding two weeks later, to determine if broccoli protects against cancer progression. Specifically, male 15-day-old C57BL/6J mice were given DEN and placed on a Western or Western+10%Broccoli diet from the age of 4 weeks through 7 months. Dietary broccoli decreased hepatic triacylglycerols, NAFLD, liver damage and tumour necrosis factor by month 5 without changing body weight or relative liver weight, but did not slow carcinogenesis, seen in 100% of mice. We conclude that broccoli, a good source of sulforaphane, slows progression of hepatic lipidosis, but not tumourigenesis in this robust model. PMID:27672403

    Full Text Available Introduction: The treatment of choice in cancer esophagus is controversial. Radiation therapy oncology group, Eastern cooperative oncology group and Cochrane studies have shown superiority of concurrent chemoradiation in inoperable carcinoma esophagus. In these studies full dose cisplatin was given every 3 weeks along with radiotherapy and hence had some toxicity. So, we started treating inoperable carcinoma esophagus patients with low dose weekly cisplatin given concurrently with radiotherapy aiming at low toxicity and similar results. Materials and Methods: A total of 31 cases of inoperable cases of carcinoma esophagus were treated with once weekly cisplatin 30 mg/m 2 along with radiotherapy 60 Gy in 30 fractions in 6 weeks on Telecobalt/Linear accelerator. Results : w0 e could achieve lower toxicity with 80%, 35% and 19% with 1, 2, and 3 year′s survival with a median survival of 18 months. So, we conclude that this regimen is better than 3 weekly chemotherapy regimen as is better tolerated with less toxicity and similar outcome.

    Vinyl-chloride monomer (VCM), a human carcinogen, has caused angiosarcoma of the liver. Recent studies have shown that VCM exposure is associated with hepatocellular cancer. In Taiwanese studies, the majority of VCM-exposed workers with liver cancer had history of hepatitis B virus (HBV) infection. To determine the role of HBV on the development of liver cancer in the VCM-exposed workers, we conducted a case-control study from a previously established polyvinyl chloride (PVC) cohort consisting of 4096 male workers from six PVC polymerization plants. A total of 18 patients with liver cancer, and 68 control subjects matched for age and specific plant of employment were selected. Detailed history of the participants that included alcohol consumption status, cigarette use, occupation, and family history of chronic liver disease were obtained using an interviewer-administered questionnaire. When the HBV surface antigen (HBsAg)-negative subjects without history of tank-cleaning were used as the reference, the HBsAg-negative subjects with history of tank-cleaning demonstrated a 4.0-fold greater risk of liver cancer (95% confidence interval: 95% CI = 0.2-69.1). The HBsAg carriers without history of tank-cleaning revealed a 25.7-fold greater risk of liver cancer (95% CI = 2.9-229.4). Whereas the HBsAg carriers with history of tank-cleaning revealed the greatest risk (matched odds ratio (ORm) 396.0, 95% CI = 22.6 -infinity) of developing liver cancer among subjects with different VCM-exposure status and HBsAg status categories. Further analysis showed the interaction term was significant (P < .01). Therefore, our results suggest an interaction between occupational VCM exposure and HBV infection for the development of liver cancer.

    The objective of this study was to observe the change in blood perfusion of liver cancer following argon-helium knife treatment with functional computer tomography perfusion imaging. Twenty-seven patients with primary liver cancer treated with argon-helium knife and were included in this study. Plain computer tomography (CT) and computer tomography perfusion (CTP) imaging were conducted in all patients before and after treatment. Perfusion parameters including blood flows, blood volume, hepatic artery perfusion fraction, hepatic artery perfusion, and hepatic portal venous perfusion were used for evaluating therapeutic effect. All parameters in liver cancer were significantly decreased after argon-helium knife treatment (p knife therapy. Therefore, CTP imaging would play an important role for liver cancer management followed argon-helium knife therapy. © The Author(s) 2014.

    2016-04-01

    Full Text Available Currently, sorafenib is the multi-target inhibitor for the treatment of advanced primary liver cancer, and can effectively prolong the progression-free survival and overall survival in patients with advanced primary liver cancer. The application of sorafenib in the targeted therapy for liver cancer has become a hot topic. Major targets or signaling pathways include Raf/Mek/Erk, Jak/Stat, PI3K/Akt/mTOR, VEGFR and PDGFR, STAT, microRNA, Wnt/β-catenin, autolysosome, and tumor-related proteins, and sorafenib can regulate the proliferation, differentiation, metastasis, and apoptosis of liver cancer cells through these targets. This article reviews the current research on the action of sorafenib on these targets or signaling pathways to provide useful references for further clinical research on sorafenib.

    Primary liver cancer remains one of the most lethal malignancies worldwide. Due to differences in prevalence of etiological factors the incidence of primary liver cancer varies among the world, with a peak in East-Asia. As this disease is still lethal in most of the cases, research has to be done to improve our understanding of the disease, offering insights for possible treatment options. For this purpose, animal models are widely used, especially mouse models. In this review, we describe the different types of mouse models used in liver cancer research, with emphasis on genetically engineered mice used in this field. We focus on hepatocellular carcinoma (HCC), as this is by far the most common type of primary liver cancer, accounting for 70%-85% of cases. PMID:19058325

    An inflammatory myofibroblastic tumour (IMFT) is a rare mesenchymal neoplasm characterised by anaplastic lymphoma kinase (ALK) gene rearrangements. We assessed the activity and safety of crizotinib, a tyrosine kinase inhibitor, targeting ALK in patients with advanced IMFT either with or without ALK alterations. We did a multicentre, biomarker-driven, single-drug, non-randomised, open-label, two-stage phase 2 trial (European Organisation for Research and Treatment of Cancer 90101 CREATE) at 13 study sites (five university hospitals and eight specialty clinics) in eight European countries (Belgium, France, Germany, Italy, Netherlands, Poland, Slovakia, and the UK). Eligible participants were patients aged at least 15 years with a local diagnosis of advanced or metastatic IMFT deemed incurable with surgery, radiotherapy, or systemic therapy; measurable disease; an Eastern Cooperative Oncology Group performance status of 0-2; and adequate haematological, renal, and liver function. Central reference pathology was done for confirmation of the diagnosis, and ALK positivity or negativity was assessed centrally using immunohistochemistry and fluorescence in-situ hybridisation based on archival tumour tissue and defined as ALK immunopositivity or rearrangements in at least 15% of tumour cells. Eligible ALK-positive and ALK-negative patients received oral crizotinib 250 mg twice per day administered on a continuous daily dosing schedule (the duration of each treatment cycle was 21 days) until documented disease progression, unacceptable toxicity, or patient refusal. If at least two of the first 12 eligible and assessable ALK-positive patients achieved a confirmed complete or partial response according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, a maximum of 35 patients were to be enrolled. If at least six ALK-positive patients achieved a confirmed response, the trial would be deemed successful. The primary endpoint was the proportion of patients who achieved

    In Australia, liver cancer incidence is rising, particularly among people born in hepatitis B-endemic countries. We sought to build an understanding of the information needs of people affected by liver cancer, to inform the design of in-language consumer information resources. We searched the World Wide Web for available in-language consumer information and conducted a literature search on consumers' information needs and their preferred means of accessing it. Qualitative data collection involved bilingual researchers conducting focus group discussions (26 participants) and in-depth interviews (22 participants) with people affected by liver cancer in English, Vietnamese, Cantonese and Mandarin. Sessions were audio-recorded, transcribed, translated and thematically analysed. The key themes and salient findings informed the development of in-language multimedia information resources. Many consumer resources did not cater for people with low literacy levels. The participants wanted more information on cancer diagnostic and treatment options, nutrition and Chinese Medicine and experienced communication challenges speaking to health professionals. While Vietnamese speakers relied entirely on information provided by their doctors, other participants actively searched for additional treatment information and commonly used the Internet to source it. We developed multilingual, multimedia consumer information resources addressing identified consumer information needs through an iterative process, in collaboration with our multilingual consumer panel. These resources are available in four languages, as separate modules accessible online and in DVD format. This process enabled the development of user-friendly patient resources, which complement health-care provider information and supports informed patient decision making. © 2016 The Authors.

    Full Text Available Imaging is essential in accurately detecting, staging, and treating primary liver cancer (hepatocellular carcinoma [HCC], one of the most prevalent and lethal malignancies. We developed a novel multifunctional nanoparticle (NP specifically targeting glypican-3 (GPC3, a proteoglycan implicated in promotion of cell growth that is overexpressed in most HCCs. Quantitative real-time polymerase chain reaction was performed to confirm the differential GPC3 expression in two human HCC cells, Hep G2 (high and HLF (negligible. These cells were treated with biotin-conjugated GPC3 monoclonal antibody (αGPC3 and subsequently targeted using superparamagnetic iron oxide NPs conjugated to streptavidin and Alexa Fluor 647. Flow cytometry demonstrated that only GPC3-expressing Hep G2 cells were specifically targeted using this αGPC3-NP conjugate (fourfold mean fluorescence over nontargeted NP, and magnetic resonance imaging (MRI experiments showed similar findings (threefold R2 relaxivity. Confocal fluorescence microscopy localized the αGPC3 NPs only to the cell surface of GPC3-expressing Hep G2 cells. Further characterization of this construct demonstrated a negatively charged, monodisperse, 50 nm NP, ideally suited for tumor targeting. This GPC3-specific NP system, with dual-modality imaging capability, may enhance pretreatment MRI, enable refined intraoperative HCC visualization by near-infrared fluorescence, and be potentially used as a carrier for delivery of tumor-targeted therapies, improving patient outcomes.

    Full Text Available primary treatment for unresectable hepatocellular carcinoma (HCC. In this unit, 185 patients with a new diagnosis of HCC not amenable to surgery were seen between 1988 and 1991. Intended therapy for these patients was chemoembolisation with doxorubicin (60 mg/m2 and lipiodol, repeated at six week intervals until it was technically no longer possible o.r until complete tumour response had been obtained. Chemoembolisation was possible in 67 of the 185 (37%. Reasons for exclusion were portal vein occlusion (n=36, decompensated cirrhosis (n 44, distant metastases (n=5, diffuse tumour or unsuitable anatomy (tumour or vasculature (n=11, patient refusal (n=11, and other (n=11. Patients excluded from treatment survived for a median of 10 weeks (range 3 days-19 months. In patients treated, 18 had small HCC (4cm and 49 had large or multifocal HCC. Chemoembolisation was carried out a median of two sessions for small and three sessions for large tumours. Ten of 18 patients with small HCC showed a 50% or greater reduction in tumour size. Five of 49 patients with large or multifocal tumours showed a response to treatment. Median overall survival for treated patients was 36 weeks (range 3 days–4 years. One patient has subsequently undergone liver transplantation with no recurrence and minimal residual disease at transplantation. Two other patients are alive three years after chemoembolisation, one with no evidence of recurrent disease. No patient was thought suitable for surgery after their response to chemoembolisation. Chemotherapy related complications were seen in 22%. Complications were significantly more common in patients with larger tumours and poor liver reserve. Five patients died as a result of chemotherapy related complications. In conclusion, only one third of UK patients with unresectable HCC are treatable by chemoembolisation. Results with small tumours are encouraging, with a high response rate and the possibility of surgical intervention in

    Patients with gastric cancer and liver metastases are believed not to benefit from gastric resection. In 43 patients with strong suspicion of-or proven-gastric cancer, fit for elective, radical surgery, preoperative liver scintigraphy was performed, in an attempt to select patients with liver metastases before laparotomy. Liver scintigraphy identified 6 out of 7 patients with metastases. Percutaneous scan-guided fine-needle aspiration biopsy verified 4 true positive scintigrams. True positive scintigrams in 2 patients heralded a change in the planned treatment. We consider that a preoperative liver scintigraphy in a population thus selected is beneficial in the planning of treatment: only patients with a negative scan-guided fine-needle aspiration biopsy should be operated upon.

    In order to clarify the differences in past history, nutritional condition and, consumption of alcohol and tobacco, and liver dysfunction between the thorotrast patients who developed primary liver cancer and those who did not, 103 persons who had no primary liver cancer in January 1980 were studied. All subjects were military men who had undergone angiography with thorotrast between 1943 and 1946. Twenty persons developed hepatocellular carcinoma and 16 developed intrahepatic bile duct carcinoma by April 1987, whereas 67 are still alive without any cancer. There was no difference in age or period after thorotrast infusion between those two groups of patients in January 1980. A difference in history of hepatitis and/or jaundice and presence of hepatic dysfunction was found between the subjects who developed primary liver cancers and those who did not. These findings suggest that an anamnestic history of hepatitis and liver dysfunction are risks for development of thorotrast-induced liver cancer. On the basis of the above findings, early detection of liver dysfunction offers a possibility of early diagnosis of primary liver cancer

    Objective: To study severe and rare complications of transarterial chemoembolization (TACE) for liver cancer. Methods: Clinical records of severe and rare complications following TACE in 1348 cases of liver cancer from January 1997 to February 2004 were studied retrospectively. Results: A total of 2012 TACE procedures were performed for 1348 patients. There were 3 cases of spontaneous rupture of liver cancer, 1 case of perforation of duodenum, 3 cases of liver abscess (1 of them was associated with sepsis), 1 case of pulmonary embolism, 1 case of spasm of the hepatic artery, 40 cases of hepatic artery occlusion, 3 cases of femoral nerve injury, 1 case of bilioma and 1 case of acute renal failure. Conclusion: Although the severe complications of TACE are rare, the procedure should be done cautiously including super selection of hepatic artery, slow infusion of lipiodol, careful postoperative observations and early detection and management of complications

    Objective: To observe the therapeutic effect of angiogenesis inhibitor combined with radiotherapy on liver metastasis model of colon cancer. Methods: Nude mice liver metastasis model of colon cancer was established with human colon cancer cells line (LS174T) inoculated into mice' spleen and followed by splenectomy. Angiogenesis inhibitor 2-ME and radiotherapy were administered after-wads. The growth inhibition effect on metastases and neovessel was examined. Results: The incidences of liver metastasis were 100% in this intrasplenic injection model. The mean weight and microvessel density 4 weeks after inoculation were 53.6 ± 4.7 mg, 8.4 ± 1.7 in treatment group as compared to 173.9 ± 11.6 mg, 41.2 ± 6.3 in control group respectively. Conclusion: 2-ME combined with radiotherapy has significant inhibition on the growth of liver metastases. Angiogenesis inhibition is one of the mechanisms of its efficiency. (authors)

    Hepatocellular carcinoma is one of the most common types of liver cancer causing death all over the world. Although early-stage liver cancer can sometimes be treated with partial hepatectomy, liver transplantation, ablation, and embolization, sorafenib treatment is the only approved systemic therapy for advanced HCC. The aim of this research is to develop tools and methods to understand the individuality of hepatocellular carcinoma. Microfluidic cell-culture platform has been developed to observe behavior of single-cells; fluorescence microscopy has been implemented to investigate phenotypic changes of cells. Our preliminary data proved high-level heterogeneity of hepatocellular carcinoma while verifying limited growth of liver cancer cell lines on the silicon wafer.

    To investigate the roles of the γ-aminobutyric acid (GABA) in the metastasis of hepatocellular carcinoma (HCC) and to explore the potential of a novel therapeutic approach for the treatment of HCC. The expression levels of GABA receptor subunit genes in various HCC cell lines and patients‘ tissues were detected by quantitative real-time polymerase chain reaction and Western blot analysis. Transwell cell migration and invasion assays were carried out for functional analysis. The effects of GABA on liver cancer cell cytoskeletal were determined by immunofluorescence staining. And the effects of GABA on HCC metastasis in nude mice were evaluated using an in vivo orthotopic model of liver cancer. The mRNA level of GABA receptor subunits varied between the primary hepatocellular carcinoma tissue and the adjacent non-tumor liver tissue. GABA inhibited human liver cancer cell migration and invasion via the ionotropic GABA A receptor as a result of the induction of liver cancer cell cytoskeletal reorganization. Pretreatment with GABA also significantly reduced intrahepatic liver metastasis and primary tumor formation in vivo. These findings introduce a potential and novel therapeutic approach for the treatment of cancer patients based on the modulation of the GABAergic system

    Liver cancer is one of the most common malignancies of the digestive system. Minimally invasive ablation procedures have become one of the major means for treating unresectable multifocal liver cancer and have been extensively applied in primary and metastatic liver cancer treatment. Laparoscopic B-ultrasound-guided microwave ablation is an example of the progress made in this field. To analyze and summarize the results of and experience with laparoscopic B-ultrasound-guided microwave ablation for multifocal primary liver cancer; moreover, the ablation effects were compared between tumors of different sizes. Laparoscope-guided needle ablation was conducted on 84 lesions from 32 patients with primary liver cancer based on tumor size, quantity, and location. Moreover, the perioperative data, ablation effects according to tumor size, and long-term follow-up results were analyzed. Among the 84 nodules treated via microwave ablation, tumors measuring ≤ 3 cm demonstrated complete ablation upon imaging analysis conducted 1 month after surgery. Moreover, 5 of the tumors measuring > 3 cm demonstrated incomplete ablation. In these cases, a second procedure was performed, until imaging studies confirmed that complete ablation was achieved. Laparoscopic microwave ablation allows for precise puncture positioning, an effective ablation range, and safe and feasible surgery, which is especially suitable for liver tumors located in sites difficult to access.

    A prospective phase II trial was conducted to evaluate the effectiveness and toxicity of regional hyperthermia and whole liver irradiation (WLI) for numerous chemorefractory liver metastases from colorectal cancer. Enrolled patients had numerous chemorefractory hepatic metastases from colorectal cancer. Five sessions of hyperthermia and seven fractions of 3-gray WLI were planned. Health-related quality of life (HRQoL) was determined using the Korean version of the European Organization for Research and Treatment of Cancer quality of life questionnaire C-30 and the Functional Assessment of Cancer Therapy-Hepatobiliary version 4.0. Objective and pain response was evaluated. A total of 12 patients consented to the study and the 10 who received WLI and hyperthermia were analyzed. WLI was completed as planned in nine patients and hyperthermia in eight. Pain response was partial in four patients and stable in four. Partial objective response was achieved in three patients (30.0%) and stable disease was seen in four patients at the 1-month follow-up. One patient died 1 month after treatment because of respiratory failure related to pleural metastasis progression. Other grade III or higher toxicities were detected in three patients; however, all severe toxicities were related to disease progression rather than treatment. No significant difference in HRQoL was noted at the time of assessment for patients who were available for questionnaires. Combined WLI and hyperthermia were well tolerated without severe treatment-related toxicity with a promising response from numerous chemorefractory hepatic metastases from colorectal cancer.

    Evaluation of the liver for focal lesions is extremely important because the liver is one of the most common sites for metastatic disease. Most patients with metastatic deposits to the liver have a survival rate of about 6 months. Thus, metastatic disease to the liver has an extremely grave prognosis. In the past patients with hepatic lesions had no therapeutic recourse. However, with recent aggressive surgical advances (such as partial hepatectomies) and hepatic artery embolization, survival of patients with hepatic metastases has increased. Thus it is important for noninvasive imaging not only to detect lesions early in their course, but also to give their true hepatic involvement and the extent of the neoplastic process elsewhere in the body. Recent advances in imaging have been rapidly changing over the past 5 years. These changes have been more rapid in computed tomography (CT) and ultrasound than in radionuclide imaging. Thus, the question addressed in this chapter is: What is the relationship of hepatic ultrasound to the other current diagnostic modalities in detecting metastatic liver disease and other focal liver lesions? Also, what is its possible future relationship to nuclear magnetic resonance?

    Full Text Available We report a case of liver metastasis of lung carcinoma with portal vein tumor thrombus (PVTT. Although the primary lesion of lung tumor remained unchanged, the patient rapidly developed wide-spread metastases and formed PVTT of liver metastasis. The primary lesion showed features of mixed Clara and bronchial surface epithelial cell component type adenocarcinoma with small foci of micropapillary pattern. Micropapillary pattern was observed in the metastatic lesions in the liver and PVTT. Micropapillary pattern lung adenocarcinoma may develop rapid metastases and cause PVTT associated with liver metastasis. We should perform a detailed examination to establish correct diagnosis.

    In Germany between 1930 and 1950, an estimated 10,000 to 20,000 patients received Thorostrast injections, mostly for angiographic examinations. About 59% of the intravascularly injected Thorotrast was retained by the liver. Based on a mean injected volume of 25 ml and an average exposure time of about 40 years, Thorotrast patients received a mean liver dose of about 9.5 Gy. As a consequence, about 20% of the 2,326 Thorotrast patients examined in the German Thorotrast Study died of liver tumors, while only 2 cases of primary liver tumors were observed in the 1,890 control patients

    Full Text Available Objective: To study the correlation of serum GP73, SOD and GPC3 contents with cell proliferation and angiogenesis in liver cancer lesion. Methods: Patients who were diagnosed with primary liver cancer in Jianghan Oilfield General Hospital between June 2014 and February 2017 were selected as liver cancer group, and healthy subjects who received physical examination in Jianghan Oilfield General Hospital during the same period were selected as control group. Serum was collected from two groups of subjects to determine the contents of GP73, SOD and GPC3; liver cancer lesion and adjacent lesion were collected from liver cancer group to determine the expression of cell proliferation molecules and angiogenesis molecules. Results: Serum GP73 and GPC3 levels of liver cancer group were obviously higher than those of control group while SOD content was obviously lower than that of control group; DNMT3B, STC2, SIRT6, LETM1, EphB4, SULT2B1, HIF-1α, VEGF, Ang-2, HGF and TGF-β1 protein expression levels in liver cancer lesion of liver cancer group were significantly higher than those in adjacent lesion; DNMT3B, STC2, SIRT6, LETM1, EphB4, SULT2B1, HIF-1α, VEGF, Ang-2, HGF and TGF-β1 protein expression levels in liver cancer lesion of liver cancer group were positively correlated with serum GP73 and GPC3 levels, and negatively correlated with serum SOD level. Conclusion: The changes of GP73, SOD and GPC3 levels in the serum of patients with liver cancer are closely related to the cell proliferation and angiogenesis in liver cancer lesion.

    The aim of the present study was to establish an animal liver metastasis model with human colon cancer and investigate the inhibitory effect of the wild type (WT) p53 gene combined with thymidine kinase/ganciclovir (TK/GCV) and cytosine deaminase/5-fluorocytosine (CD/5-FC) systems on liver metastasis of colon cancer. A nude mouse liver metastasis model with human colon cancer was established via a spleen cultivation method. A total of 32 nude mice were randomly divided into four groups, each group with eight mice. Group 1 mice received splenic injections of SW480 cells (control group), while group 2 mice were injected with SW480/p53 cells in the spleen. Group 3 mice were administered splenic injections of SW480/TK-CD cells, and GCV and 5-FC were injected into the abdominal cavity. Finally, group 4 mice received splenic injections of SW480/p53 cells mixed in equal proportion with SW480/TK-CD cells, as well as GCV and 5-FC injections in the abdominal cavity. These cells described were constructed in our laboratory and other laboratories. The number of liver metastatic tumors, the liver metastasis rate, conventional pathology, electron microscopy and other indicators in the nude mice of each group were compared and observed. The nude mouse liver metastasis model with human colon cancer was successfully established; the liver metastasis rate of the control group was 100%. The results demonstrated that the rate of liver metastasis in the nude mice in each treatment group decreased, as well as the average number of liver metastatic tumors. Furthermore, the effect of the treatment group with genetic combination (group 4) was the most effective, demonstrating that WTp53 had a synergistic effect with TK/GCV and CD/5-FC. Therefore, the present study successfully established a mouse model of liver metastasis with colon cancer by injecting human colon cancer cells in the spleen. Combined gene therapy was shown to have a synergistic effect, which effectively inhibited the

    Primary liver cancers (i.e. hepatocellular carcinoma or cholangiocarcinoma) are worldwide some of the most frequent cancers, with rapidly fatal liver failure in a large majority of patients. Curative therapy consists of surgery (i.e. resection or liver transplantation), but only 10-20% of patients are candidates for this. In other patients, a variety of palliative treatments can be given, such as chemoembolization, radiofrequency ablation or recently introduced tyrosine kinase inhibitors, e.g. sorafenib. Colorectal cancer is the second most lethal cancer in Europe and liver metastases are prevalent either at diagnosis or in follow-up. These patients are usually treated by a sequence of surgery, chemotherapy and antibody therapy [Okuda et al. (Cancer 56:918-928, 1985); Schafer and Sorrell (Lancet 353:1253-1257, 1999); Leong et al. (Arnold, London, 1999)]. Radioembolization is an innovative therapeutic approach defined as the injection of micron-sized embolic particles loaded with a radioisotope by use of percutaneous intra-arterial techniques. Advantages of the use of these intra-arterial radioactive compounds are the ability to deliver high doses of radiation to small target volumes, the relatively low toxicity profile, the possibility to treat the whole liver including microscopic disease and the feasibility of combination with other therapy modalities. Disadvantages are mainly due to radioprotection constraints mainly for (131)I-labelled agents, logistics and the possibility of inadvertent delivery or shunting [Novell et al. (Br J Surg 78:901-906, 1991)]. The Therapy, Oncology and Dosimetry Committees have worked together in order to revise the European Association of Nuclear Medicine (EANM) guidelines on the use of the radiopharmaceutical (131)I-Lipiodol (Lipiocis®, IBA, Brussels, Belgium) and include the newer medical devices with (90)Y-microspheres. (90)Y is either bound to resin (SIR-Spheres®, Sirtex Medical, Lane Cove, Australia) or embedded in a glass

    Blockade of the renin angiotensin system (RAS) via angiotensin I converting enzyme (ACE) inhibition reduces growth of colorectal cancer (CRC) liver metastases in a mouse model. In this work we defined the expression of the various components of the RAS in both tumor and liver during the progression of this disease. Immunohistochemistry and quantitative RT-PCR was used to examine RAS expression in a mouse CRC liver metastases model. CRC metastases and liver tissue was assessed separately at key stages of CRC liver metastases development in untreated (control) mice and in mice treated with the ACE inhibitor captopril (750 mg/kg/day). Non-tumor induced (sham) mice indicated the effect of tumors on normal liver RAS. The statistical significance of multiple comparisons was determined using one-way analysis of variance followed by Bonferroni adjustment with SAS/STAT software. Reduced volume of CRC liver metastases with captopril treatment was evident. Local RAS of CRC metastases differed from the surrounding liver, with lower angiotensin II type 1 receptor (AT1R) expression but increased ANG-(1-7) receptor (MasR) compared to the liver. The AT1R localised to cancer and stromal infiltrating cells, while other RAS receptors were detected in cancer cells only. Tumor induction led to an initial increase in AT1R and ACE expression while captopril treatment significantly increased ACE expression in the final stages of tumor growth. Conversely, captopril treatment decreased expression of AT1R and angiotensinogen. These results demonstrate significant changes in RAS expression in the tumor-bearing captopril treated liver and in CRC metastases. The data suggests the existence of a tumor-specific RAS that can be independently targeted by RAS blockade

    The Mayak Production Association (MPA) worker registry has shown evidence of plutonium-induced health effects. Workers were potentially exposed to plutonium nitrate [(239)Pu(NO(3))(4)] and plutonium dioxide ((239)PuO(2)). Studies of plutonium-induced health effects in animal models can complement human studies by providing more specific data than is possible in human observational studies. Lung, liver, and bone cancer mortality rate ratios in the MPA worker cohort were compared to those seen in beagle dogs, and models of the excess relative risk of lung, liver, and bone cancer mortality from the MPA worker cohort were applied to data from life-span studies of beagle dogs. The lung cancer mortality rate ratios in beagle dogs are similar to those seen in the MPA worker cohort. At cumulative doses less than 3 Gy, the liver cancer mortality rate ratios in the MPA worker cohort are statistically similar to those in beagle dogs. Bone cancer mortality only occurred in MPA workers with doses over 10 Gy. In dogs given (239)Pu, the adjusted excess relative risk of lung cancer mortality per Gy was 1.32 (95% CI 0.56-3.22). The liver cancer mortality adjusted excess relative risk per Gy was 55.3 (95% CI 23.0-133.1). The adjusted excess relative risk of bone cancer mortality per Gy(2) was 1,482 (95% CI 566.0-5686). Models of lung cancer mortality based on MPA worker data with additional covariates adequately described the beagle dog data, while the liver and bone cancer models were less successful.

    As having used Ho-166 Chitosan complex, this study was designed for the development of new therapeutic agent in the treatment of liver cancer (hepatocellular carcinoma). During the period of 3 years from April 1, 1997 to March 31, 2000, this project was successfully performed on the base of clinical experience with percutaneous Ho-166 CHICO injection in the treatment of liver cancer'. In order to evaluate the biodistribution and effect of Ho-166 CHICO was performed in 50 patients, who had the progressed liver cancer with range of 3-10cm in diameter. After the administration of the complex materials, we evaluated the therapeutic effect as well as complication by the follow-up study that included laboratory examination, radioactivity counting and various imaging modalities. 1) In animal experiment, radioactivity of target liver was ranged between 27-33% of total body one, urine excretion between 0.17-0.24 %. White blood cell and platelet counts start diminishing within 7 days and at maximum within 4 weeks after administration of complex materials. In tissue changes of target liver was revealed no significant change in the tumor dose of Ho-166, but periportal fibrosis and massive tissue necrosis in the high ones. 2) In clinical study, total necrosis of tumor is 66%, partial 10% and non-response 24% among 50 patients' liver cancer. The most important complication were leukopenia and thrombocytopenia (82%), the remained was abdominal pain(34%), skin reaction(12%), bile duct obstruction(10%), liver abscess(6%) etc. Conclusively intraarterial injection of Ho-166 CHICO was effective in the treatment of larger and progressed liver cancer. 19 refs., 14 figs., 8 tabs.

    Fisetin (3,3',4',7-tetrahydroxyflavone), a natural abundant flavonoid, is produced in different vegetables and fruits. Fisetin has been reported to relate to various positive biological effects, including anti-proliferative, anticancer, anti-oxidative and neuroprotective effects. Dopamine receptors (DRs) belonging to G protein‑coupled receptor family, are known as the target of ~50% of all modern medicinal drugs. DRs consist of various proteins, functioning as transduction of intracellular signals for extracellular stimuli. We found that fisetin performed as DR2 agonist to suppress liver cancer cells proliferation, migration and invasion. Caspase-3 signaling was activated to induce apoptosis for fisetin administration. Furthermore, TGF‑β1 was also inhibited in fisetin-treated liver cancer cells, reducing epithelial-mesenchymal transition (EMT). Additionally, fisetin downregulated VEGFR1, p-ERK1/2, p38 and pJNK, ameliorating liver cancer progression. In vivo, the orthotopically implanted tumors from mice were inhibited by fisetin adminisatration accompanied by prolonged survival rate and higher levels of dopamine. Together, the results indicated a novel therapeutic strategy to suppress liver cancer progression associated with DR2 regulation, indicating that dopamine might be of importance in liver cancer progression.

    AIM:To establish an animal model with human hepatocyte-repopulated liver for the study of liver cancer metastasis.METHODS:Cell transplantation into mouse livers was conducted using alpha-fetoprotein (AFP)-producing human gastric cancer cells (h-GCCs) and h-hepatocytes as donor cells in a transgenic mouse line expressing urokinase-type plasminogen activator (uPA) driven by the albumin enhancer/promoter crossed with a severe combined immunodeficient (SCID) mouse line (uPA/SCID mice).Host mice were divided into two groups (A and B).Group A mice were transplanted with h-GCCs alone,and group B mice were transplanted with h-GCCs and h-hepatocytes together.The replacement index (RI),which is the ratio of transplanted h-GCCs and h-hepatocytes that occupy the examined area of a histological section,was estimated by measuring h-AFP and h-albumin concentrations in sera,respectively,as well as by immunohistochemical analyses of h-AFP and human cytokeratin 18 in histological sections.RESULTS:The h-GCCs successfully engrafted,repopulated,and colonized the livers of mice in group A (RI =22.0% ± 2.6%).These mice had moderately differentiated adenocarcinomatous lesions with disrupted glandular structures,which is a characteristics feature of gastric cancers.The serum h-AFP level reached 211.0 ± 142.2 g/mL (range,7.1-324.2 g/mL).In group B mice,the h-GCCs and h-hepatocytes independently engrafted,repopulated the host liver,and developed colonies (RI =12.0% ± 6.8% and 66.0% ± 12.3%,respectively).h-GCC colonies also showed typical adenocarcinomatous glandular structures around the h-hepatocyte-colonies.These mice survived for the full 56day-study and did not exhibit any metastasis of h-GCCs in the extrahepatic regions during the observational period.The mice with an h-hepatocyte-repopulated liver possessed metastasized h-GCCs and therefore could be a useful humanized liver animal model for studying liver cancer metastasis in vivo.CONCLUSION:A novel animal model of

    2017-08-01

    Full Text Available Regorafenib is a multikinase inhibitor which showed benefits in pretreated metastatic colorectal cancer patients. Hepatotoxicity has been described as a frequent side effect. We report the case of a 65-year-old patient presenting with jaundice, fever, and hepatocellular insufficiency which led to death of the patient. She had previously been treated with several lines of chemotherapy for sub- and diaphragmatic ganglionic metastases of a colon adenocarcinoma. There were no liver metastases. The fatal liver failure occurred at the beginning of treatment with regorafenib at a dosage of 3 tablets per day. No concomitant treatment was given, and other causes of liver damage were eliminated. The liver biopsy showed hepatocyte necrosis with lymphocyte infiltration. This observation illustrates the risk of severe hepatic involvement typically occurring within the first 2 months of treatment. Monitoring liver biology every 2 weeks is essential during the first 2 months to detect any hepatotoxicity.

    The liver is the site of breast cancer metastasis in 50% of patients with advanced disease. Tumour markers have been demonstrated as being useful in follow-up of patients with breast cancer, in early detection of recurrence of breast cancer after radical surgical treatments, and in assessing oncologic therapy effect, but no study has been carried out on their usefullness in distinguishing benign liver lesions from breast cancer metastases. The aim of this study was therefore to evaluate the importance of tumour markers carcinoembryonic antigen (CEA), carbohydrate antigen CA19-9 (CA19-9), thymidine kinase (TK), tissue polypeptide antigen (TPA), tissue polypeptide-specific antigen (TPS) and cytokeratin 19 fragment (CYFRA 21-1) in differential diagnosis between benign liver lesions and liver metastases of breast cancer. The study includes 3 groups: 22 patients with liver metastases of breast cancer; 39 patients with benign liver lesions (hemangioma, focal nodular hyperplasia, liver cyst, hepatocellular adenoma); and 21 patients without any liver disease or lesion that were operated on for benign extrahepatic diseases (groin hernia, varices of lower limbs) as a control group. The serum levels of tumour markers were assessed by means of immunoanalytical methods. Preoperative serum levels of CYFRA 21-1, TPA, TPS and CEA were significantly higher in patients with liver metastases of breast cancer in contrast to healthy controls and patients with benign liver lesions (p-value<0.05). Serum levels of CA19-9 and TK were higher in patients with malignancy in comparison with benign liver disease and healthy controls but these differences were not statistically significant. Tumour markers CEA, CYFRA 21-1, TPA and TPS can be recommended as a good tool for differential diagnosis between liver metastases of breast cancer and benign liver lesions.

    Full Text Available BACKGROUND: Accumulating evidence supports that tumor growth and cancer relapse are driven by cancer stem cells. Our previous work has demonstrated the existence of CD90(+ liver cancer stem cells (CSCs in hepatocellular carcinoma (HCC. Nevertheless, the characteristics of these cells are still poorly understood. In this study, we employed a more sensitive RNA-sequencing (RNA-Seq to compare the gene expression profiling of CD90(+ cells sorted from tumor (CD90(+CSCs with parallel non-tumorous liver tissues (CD90(+NTSCs and elucidate the roles of putative target genes in hepatocarcinogenesis. METHODOLOGY/PRINCIPAL FINDINGS: CD90(+ cells were sorted respectively from tumor and adjacent non-tumorous human liver tissues using fluorescence-activated cell sorting. The amplified RNAs of CD90(+ cells from 3 HCC patients were subjected to RNA-Seq analysis. A differential gene expression profile was established between CD90(+CSCs and CD90(+NTSCs, and validated by quantitative real-time PCR (qRT-PCR on the same set of amplified RNAs, and further confirmed in an independent cohort of 12 HCC patients. Five hundred genes were differentially expressed (119 up-regulated and 381 down-regulated genes between CD90(+CSCs and CD90(+NTSCs. Gene ontology analysis indicated that the over-expressed genes in CD90(+CSCs were associated with inflammation, drug resistance and lipid metabolism. Among the differentially expressed genes, glypican-3 (GPC3, a member of glypican family, was markedly elevated in CD90(+CSCs compared to CD90(+NTSCs. Immunohistochemistry demonstrated that GPC3 was highly expressed in forty-two human liver tumor tissues but absent in adjacent non-tumorous liver tissues. Flow cytometry indicated that GPC3 was highly expressed in liver CD90(+CSCs and mature cancer cells in liver cancer cell lines and human liver tumor tissues. Furthermore, GPC3 expression was positively correlated with the number of CD90(+CSCs in liver tumor tissues. CONCLUSIONS

    Objective: To evaluate the efficacy of intra-hepatic arterial infusion chemotherapy for patients with liver metastasis from breast cancer. Methods: 1993-1998 years, Thirty four patients with liver metastasis from breast cancer had received epi-adriamycin, cisplatin, mitomycin and 5-fluorouracil by intrahepatic arterial infusion chemotherapy. Twelve patients had received embolization. Results: Six patients (17.65%) had a complete response, 12 patients (35.29%) had a partial response. The overall response rate was 52.94%. Cumulative survival rates at 1, 2, 3 and 4 years were 56.90%, 25.00%, 5.00% and 5.00% respectively (Kaplan-Meier method). The median overall survival time was 11.5 months. Conclusion: Intra-hepatic arterial infusion chemotherapy is safe and effective for liver metastasis from breast cancer and should be the first choice of treatment for these patients

    Full Text Available Radiofrequency ablation (RFA is one of the most important methods for the treatment of liver cancer and has the advantages of small trauma, simple operation, and repeatability. However, for tumors in high-risk locations within 5 mm of the first and second branches of the hepatic portal vein, near the hepatic vein, the inferior vena cava, or the gallbladder, within 5 mm of the intestinal tract, under the Glisson’s capsule, and in the diaphragm, RFA has the issues of a low complete ablation rate, a high local recurrence rate, and serious complications. This article introduces the complications of RFA for liver cancer in high-risk locations and their prevention and points out that with the promotion of individualized and standardized RFA, liver cancer in these high-risk locations is no longer a contradiction for RFA.

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is a leading cause of chronic liver disease but the second cause of death among NAFLD patients are attributed to malignancies at both gastrointestinal (liver, colon, esophagus, stomach, and pancreas and extra-intestinal sites (kidney in men, and breast in women. Obesity and related metabolic abnormalities are associated with increased incidence or mortality for a number of cancers. NAFLD has an intertwined relationship with metabolic syndrome and significantly contributes to the risk of hepatocellular carcinoma (HCC, but recent evidence have fuelled concerns that NAFLD may be a new, and added, risk factor for extra-hepatic cancers, particularly in the gastrointestinal tract. In this review we critically appraise key studies on NAFLD-associated extra-hepatic cancers and speculate on how NAFLD may influence carcinogenesis at these sites.

    Liver cancer is the sixth most prevalent cancer, and the third most frequent cause of cancer-related deaths. Circular RNAs (circRNAs), a kind of special endogenous ncRNAs, have been coming back to the forefront of cancer genomics research. In this study, we used a systems biology approach to construct and analyze the circRNA molecular regulatory networks in the context of liver cancer. We detected a total of 127 differentially expressed circRNAs and 3,235 differentially expressed mRNAs. We selected the top-5 upregulated circRNAs to construct a circRNA-miRNA-mRNA network. We enriched the pathways and gene ontology items and determined their participation in cancer-related pathways such as p53 signaling pathway and pathways involved in angiogenesis and cell cycle. Quantitative real-time PCR was performed to verify the top-five circRNAs. ROC analysis showed circZFR, circFUT8, circIPO11 could significantly distinguish the cancer samples, with an AUC of 0.7069, 0.7575, and 0.7103, respectively. Our results suggest the circRNA-miRNA-mRNA network may help us further understand the molecular mechanisms of tumor progression in liver cancer, and reveal novel biomarkers and therapeutic targets.

    The mainstay of treatment for metastatic colorectal cancer is surgery. Therefore, colorectal cancer metastasis is distinctive, compared to other cancer types in which chemotherapy is the main treatment. Initially, Japan experienced medical druglag compared with western countries. However, the use of oxaliplatin for unresectable recurrent metastatic colorectal cancer became available in Japan, as well as in western countries, in 2005. We have since shifted chemotherapeutic regimens from monotherapy to combination therapy with molecular targeted agents. The combination therapy has rapidly become a standard therapy for unresectable metastatic colorectal cancer, and prognosis has dramatically increased for patients with this condition. Herein, we describe the treatment of liver metastasis of colorectal cancer, and surgery and adjuvant or neoadjuvant therapy options for resectable cancer. Furthermore, we focus on conversion therapy for unresectable cancer.

    Primary liver cancer (HCC) is recognized as the fifth most common neoplasm and the second leading cause of cancer death worldwide. Most risk factors are known, and the molecular pathogenesis has been widely studied in the past decade; however, the underlying molecular mechanisms remain to be unveiled, as they will facilitate the definition of novel biomarkers and clinical targets for more effective patient management. We utilize the B/D-HPP popular protein strategy. We report a list of popular proteins that have been highly cocited with the expression "liver cancer". Several enzymes highlight the known metabolic remodeling of liver cancer cells, four of which participate in one-carbon metabolism. This pathway is central to the maintenance of differentiated hepatocytes, as it is considered the connection between intermediate metabolism and epigenetic regulation. We designed a targeted selective reaction monitoring (SRM) method to follow up one-carbon metabolism adaptation in mouse HCC and in regenerating liver following exposure to CCl 4 . This method allows systematic monitoring of one-carbon metabolism and could prove useful in the follow-up of HCC and of chronically liver-diseased patients (cirrhosis) at risk of HCC. The SRM data are available via ProteomeXchange in PASSEL (PASS01060).

    Full Text Available IntroductionLiver cancer is the fastest increasing cancer in the United States and is one of the leading causes of cancer-related death in New York City (NYC, with wide disparities among neighborhoods. The purpose of this cross-sectional study was to describe liver cancer incidence by neighborhood and examine its association with risk factors. This information can inform preventive and treatment interventions.Materials and methodsPublicly available data were collected on adult NYC residents (n = 6,407,022. Age-adjusted data on liver and intrahepatic bile duct cancer came from the New York State Cancer Registry (1 (2007–2011 average annual incidence; and the NYC Vital Statistics Bureau (2015, mortality. Data on liver cancer risk factors (2012–2015 were sourced from the New York City Department of Health and Mental Hygiene: (1 Community Health Survey, (2 A1C registry, and (3 NYC Health Department Hepatitis surveillance data. They included prevalence of obesity, diabetes, diabetic control, alcohol-related hospitalizations or emergency department visits, hepatitis B and C rates, hepatitis B vaccine coverage, and injecting drug use.ResultsLiver cancer incidence in NYC was strongly associated with neighborhood poverty after adjusting for race/ethnicity (β = 0.0217, p = 0.013; and with infection risk scores (β = 0.0389, 95% CI = 0.0088–0.069, p = 0.011, particularly in the poorest neighborhoods (β = 0.1207, 95% CI = 0.0147–0.2267, p = 0.026. Some neighborhoods with high hepatitis rates do not have a proportionate number of hepatitis prevention services.ConclusionHigh liver cancer incidence is strongly associated with infection risk factors in NYC. There are gaps in hepatitis prevention services like syringe exchange and vaccination that should be addressed. The role of alcohol and metabolic risk factors on liver cancer in NYC warrants further study.

    Full Text Available Due to its increasing prevalence, exceeding 25% of the Western population, non-alcoholic fatty liver disease (NAFLD merits recognition as one of the most frequent chronic liver diseases (CLD and requires consideration of the associated disease-related complications and their consequences for the surveillance and treatment of patients and the socio-economy worldwide. Along with the increasing incidence of NAFLD-related cirrhosis and end-stage liver disease, the frequency of NAFLD-related hepatocellular carcinoma (HCC is rising and expected to surpass HCC related to chronic hepatitis C in the upcoming future. These epidemiologic changes will impact on the overall mortality of CLD and the requirement of organs for transplantation. Although the risk of HCC in NAFLD, similar to other CLD, is related to fibrosis (advanced fibrosis increases the risk of HCC 25-fold, there are reports suggesting a considerable rate of HCC also developing in simple hepatic steatosis. Moreover, HCC is nowadays the leading cause of obesity-related cancer mortality; cancers of other origin such as colorectal cancer are more prevalent in patients with NAFLD and obesity. The pathophysiology of HCC has mainly been studied in models of viral hepatitis. Given the expected raise in NAFLD-related HCC, a better understanding of the pathophysiology of carcinogenesis in NAFLD and obesity is desired in order to better define chemopreventive strategies. Here we review the epidemiology, aetiology, and pathogenesis of HCC on the background of NAFLD and deduce potential consequences for the management of patients in respect to the NAFLD epidemic.

    Background Recently, retrograde tracing has provided evidence for an influence of hypothalamic β-endorphin (BEP) neurons on the liver, but functions of these neurons are not known. We evaluated the effect of BEP neuronal activation on alcohol-induced liver injury and hepatocellular cancer. Methods Male rats received either BEP neuron transplants or control transplants in the hypothalamus and randomly assigned to feeding alcohol-containing liquid diet or control liquid diet for 8 weeks or to treatment of a carcinogen diethylnitrosamine (DEN). Liver tissues of these animals were analyzed histochemically and biochemically for tissue injuries or cancer. Results Alcohol-feeding increased liver weight and induced several histopathological changes such as prominent microvesicular steatosis and hepatic fibrosis. Alcohol feeding also increased protein levels of triglyceride, hepatic stellate cell activation factors and catecholamines in the liver and endotoxin levels in the plasma. However, these effects of alcohol on the liver were reduced in animals with BEP neuron transplants. BEP neuron transplants also suppressed carcinogen-induced liver histopathologies such as extensive fibrosis, large focus of inflammatory infiltration, hepatocelluar carcinoma, collagen deposition, numbers of preneoplastic foci, levels of hepatic stellate cell activation factors and catecholamines, as well as inflammatory milieu and the levels of NK cell cytotoxic factors in the liver. Conclusion These findings are the first evidence for a role of hypothalamic BEP neurons in influencing liver functions. Additionally, the data identify that BEP neuron transplantation prevents hepatocellular injury and hepatocellular carcinoma formation possibly via influencing the immune function. PMID:25581653

    From the clinical point of view, rectal cancer and colon cancer are clearly different nosological units in their progress and treatment. The aim of this study was to analyse and clarify the differences between the behaviour of liver metastases from colon and rectal cancer. The study of these factors is important for determining an accurate prognosis and indication of the most effective surgical therapy and oncologic treatment of colon and rectal cancer as a systemic disease. 223 patients with metastatic disease of colorectal carcinoma operated at the Department of Surgery, University Hospital in Pilsen between January 1, 2006 and January 31, 2012 were included in our study. The group of patients comprised 145 men (65%) and 117 women (35%). 275 operations were performed. Resection was done in 177 patients and radiofrequency ablation (RFA) in the total of 98 cases. Our sample was divided into 3 categories according to the location of the primary tumor to C (colon), comprising 58 patients, S (c. sigmoideum) in 61 patients, and R (rectum), comprising 101 patients. Significance analysis of the studied factors (age, gender, staging [TNM classification], grading, presence of mucinous carcinoma, type of operation) was performed using ANOVA test. Overall survival (OS), disease-free interval (DFI) or no evidence of disease (NED) were estimated using Kaplan-Meier curves, which were compared with the log-rank and Wilcoxon tests. As regards the comparison of primary origin of colorectal metastases in liver regardless of their treatment (resection and RFA), our study indicated that rectal liver metastases showed a significantly earlier recurrence than colon liver metastases (shorter NED/DFI). Among other factors, a locally advanced finding, further R2 resection of liver metastases and positivity of lymph node metastases were statistically significant for the prognosis of an early recurrence of the primary colon and sigmoid tumor. Furthermore, we proved that in patients with

    Incidence rates for liver cancer have increased threefold since the mid-1970s in the United States in parallel with increasing trends for obesity and type 2 diabetes mellitus (T2DM). We conducted an analysis of baseline body mass index (BMI), waist circumference (WC), and T2DM with risk of liver cancer. The Liver Cancer Pooling Project maintains harmonized data from 1.57 million adults enrolled in 14 U.S.-based prospective studies. Cox regression estimated hazard ratios (HR) and 95% confidence intervals (CI) adjusted for age, sex, study center, alcohol, smoking, race, and BMI (for WC and T2DM). Stratified analyses assessed whether the BMI-liver cancer associations differed by hepatitis sera-positivity in nested analyses for a subset of cases (n=220) and controls (n=547). After enrollment, 2,162 incident liver cancer diagnoses were identified. BMI, per 5 kg/m2, was associated with higher risks of liver cancer, more so for men (HR: 1.38; 95% CI: 1.30 to 1.46) than women (HR: 1.25; 95% CI: 1.17 to 1.35; p-interaction: 0.02). WC, per 5 cm, was associated with higher risks of liver cancer, approximately equally by sex (overall, HR: 1.08; 95% CI: 1.04 to 1.13). T2DM was associated with higher risk of liver cancer (HR: 2.61; 95% CI: 2.34 to 2.91). In stratified analyses, there was a null association between BMI and liver cancer risk for participants who were sera-positive for hepatitis. This study suggests that high BMI, high WC, and T2DM are associated with higher risks of liver cancer and that the association may differ by status of viral hepatitis infection. PMID:27742674

    INTRODUCTION: Colorectal carcinoma accounts for 10% of cancer deaths in the Western World, with the liver being the most common site of distant metastases. Resection of liver metastases is the treatment of choice, with a 5-year survival rate of 35%. However, only 5-10% of patients are suitable for resection at presentation. AIMS: To examine the referral pattern of patients with liver metastases to a specialist hepatic unit for resection. METHODOLOGY: Retrospective review of patient\\'s charts diagnosed with colorectal liver metastases over a 10-year period. RESULTS: One hundred nine (38 women, 71 men) patients with liver metastases were included, mean age 61 years; 79 and 30 patients had synchronous and metachronus metastases, respectively. Ten criteria for referral were identified; the referral rate was 8.25%, with a resection rate of 0.9%. Forty two percent of the patients had palliative chemotherapy; 42% had symptomatic treatment. CONCLUSION: This study highlights the advanced stage of colorectal cancer at presentation; in light of modern evidence-based, centre-oriented therapy of liver metastasis, we conclude that criteria of referral for resection should be based on the availability of treatment modalities.

    The aim of this study is to compare the perioperative and oncologic outcomes of open and laparoscopic approaches for concomitant resection of synchronous colorectal cancer and liver metastases. Between 2006 and 2015, all patients undergoing combined resection of primary colorectal cancer and liver metastases were included in the study (n=43). Laparoscopic and open groups were compared regarding clinical, perioperative and oncologic outcomes. There were 29 patients in the open group and 14 patients in the laparoscopic group. The groups were similar regarding demographics, comorbidities, histopathological characteristics of the primary tumor and liver metastases. Postoperative complication rate (44.8% vs . 7.1%, P=0.016) was higher, and hospital stay (10 vs . 6.4 days, P=0.001) longer in the open compared to the laparoscopic group. Overall survival (OS) was comparable between the groups (P=0.10); whereas, disease-free survival (DFS) was longer in laparoscopic group (P=0.02). According to the results, in patients, whose primary colorectal cancer and metastatic liver disease was amenable to a minimally invasive resection, a concomitant laparoscopic approach resulted in less morbidity without compromising oncologic outcomes. This suggests that a laparoscopic approach may be considered in appropriate patients by surgeons with experience in both advanced laparoscopic liver and colorectal techniques.

    BACKGROUND: High levels of intact and cleaved forms of the urokinase-type plasminogen activator receptor (uPAR) in both tissue and blood are associated with poor survival in several cancer diseases. The prognostic significance of uPAR in cholangiocarcinoma is unknown. The aims of this study were...... to determine if pre-treatment serum levels of uPAR forms and a decrease in levels during chemotherapy are predictive of survival in patients with inoperable cholangiocarcinoma. DESIGN AND METHODS: Patients with inoperable cholangiocarcinoma were consecutively included in the training set (n=108). A test set......PAR(I-III)+uPAR(II-III) after 2cycles of chemotherapy was associated with poor survival (HR=1.79, 95% CI:1.08-2.97, p=0.023, n=57). This predictor, however, was not significant in the test set (p=0.21, 26 events in 27 patients). CONCLUSION: The baseline level of uPAR(I-III)+uPAR(II-III) is a predictor of survival in inoperable...

    Full Text Available BACKGROUND AND PURPOSE: The benefit of concurrent chemoradiotherapy (CCRT in elderly patients with inoperable esophageal squamous cell carcinoma (SCC is controversial. This study aimed to assess the efficiency and safety of CCRT in elderly thoracic esophageal cancer patients. METHODS AND MATERIALS: Between January 2002 and December 2011, 128 patients aged 65 years or older treated with CCRT or radiotherapy (RT alone for inoperable thoracic esophageal SCC were analyzed retrospectively (RT alone, n = 55; CCRT, n = 73. RESULTS: No treatment-related deaths occurred and no patients experienced any acute grade 4 non-hematologic toxicities. Patients treated with CCRT developed more severe acute toxicities than patients who received RT alone. The 3-year overall survival (OS rate was 36.1% for CCRT compared with 28.5% following RT alone (p = 0.008. Multivariate analysis identified T stage and treatment modality as independent prognostic factors for survival. Further analysis revealed that survival was significantly better in the CCRT group than in the RT alone group for patients ≤ 72 years. Nevertheless, the CCRT group had a similar OS to the RT group for patients > 72 years. CONCLUSION: Our results suggest that elderly patients with inoperable thoracic esophageal SCC could benefit from CCRT, without major toxicities. However, for patients older than 72 years, CCRT is not superior to RT alone in terms of survival benefit.

    The hepato-carcinoma-intestine-pancreas (HIP) gene, also called pancreatitis-associated protein-1 (PAP1) or Reg III {alpha}, is activated in most human hepatocellular carcinomas (HCCs) but not in normal liver, which suggests that HIP regulatory sequence could be used as efficient liver tumor-specific promoters to express a therapeutic polynucleotide in liver cancer. The sodium iodide sym-porter (NIS), which has recognized therapeutic and reporter gene properties, is appropriate to evaluate the transcriptional strength and specificity of the HIP promoter in HCC. For this purpose, we constructed a recombinant rat HIP-NIS adeno-viral vector (AdrHIP-NIS), and evaluated its performance as a mediator of selective radio-iodide uptake in tumor hepatocytes. Western blot, immunofluorescence, and iodide uptake assays were performed in AdrHIP-NIS-infected primary hepatocytes and transformed hepatic and non-hepatic cells. Nuclear imaging, tissue counting and immuno-histo-chemistry were performed in normal and HCC-bearing Wistar rats infected with AdrHIP-NIS intra-tumorally or via the hepatic artery. In AdrHIP-NIS-infected transformed hepatic cells, functional NIS was strongly expressed, as in cells infected with a cytomegalovirus-NIS vector. No NIS expression was found in AdrHIP-NIS-infected normal hepatocytes or transformed non-hepatic cells. In rats bearing multi-nodular HCC, AdrHIP-NIS triggered functional NIS expression that was preferential in tumor hepatocytes. Administration of 18 mCi of {sup 131}I resulted in the destruction of AdrHIP-NIS-injected nodules. This study has identified the rHIP regulatory sequence as a potent liver tumor-specific promoter for the transfer of therapeutic genes, and AdrHIP-NIS-mediated. {sup 131}I therapy as a valuable option for the treatment of multi-nodular HCC.

    To examine the associations between socioeconomic/occupational factors and liver cancer at various anatomic sites (including primary liver, gallbladder and other cancers). We carried out a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated in different social classes and occupations. For primary liver cancer, farmers were at a decreased risk; increased risks were observed for male sales agents, journalists, seamen, waiters, cooks and female beverage manufacture workers. Similar patterns were observed for gallbladder cancer; workers employed as journalists, sales agents, cooks and stewards, and public safety workers showed increased risk. Only male transport workers showed increased risk of cancers in other parts. Occupations with high consumption of alcohol and/or high prevalence of smoking associated with a risk of liver and gallbladder cancers. The present study suggests that the effects of socioeconomic factors on liver cancer of different subsites are similar; alcohol drinking is a risk factor of gallbladder cancer because of the covariation of primary liver and gallbladder cancers in occupational groups.

    Fairly many cases of delayed disorders caused by thorotrast have been reported. The authors experienced a case of 65 year old male who had received an infusion of thorotrast solution at the old army hospital 38 years ago and died for liver cirrhosis and hepatic cancer (double cancer of hepatoma and cholangiocarcinoma). By the biopsy after his death, alpha ray was proved in granules of foreign body in hepatic tissues, and in corporation with its contrast, it was certified that a chain of abnormal shadows mainly seen in the liver and the spleen, on the scout film of the abdomen before death, was caused by thorotrast. From pathological findings in hepatic cancers, hepatoma was recognized in the right lobe and cholangioma, in the left lobe, and there was no pathological relationship between two cancers. Namely, it was double cancer within the same organ. Case of double cancer in the liver such as this case was thought to be very rare in Japan, and a few literature considerations were also reported.

    The carcinogenicity of 241 Am, relative to thorotrast, has been determined in two species of mice: the grasshopper mouse (Onychomys leucogaster) and the deer mouse (Peromyscus maniculatus). These species were used since both have high uptakes of Pu and Am and, unlike conventional mice and rats, both retain relatively high concentrations of plutonium and americium in their livers. The study indicated that the liver carcinogenicity of comparable rad doses of 241 Am or thorotrast is approximately equal. The toxicity ratio ( 241 Am/thorotrast) for liver cancer induction approximated 1.2 with a range of about 0.6 to 1.6. This suggested that nonradiation factors of thorotrast were not significant in liver tumor induction. (orig.)

    Abstract Rationale: Regorafenib is effective for metastatic colorectal cancer but its toxicity such as hemorrhage should be considered. The safety of regorafenib for the patient with the liver disease is not known. Patient concerns: Seventy-one-year old man of colon cancer had myodesopsia and blood stool after 14 days from the initiation of regorafenib administration with 50% dose reduction due to liver dysfunction. Diagnoses: Fundus examination revealed hemorrhage of the retinal vein. Interventions: Regorafenib treatment was discontinued and observational therapy was pursued. Outcomes: Retinal and gastrointestinal hemorrhage resolved in 1 week. Lessons: Retinal hemorrhage should be considered as the differential diagnosis of myodesopsia in the patient treated by regorafenib. Safety and pharmacokinetic of continuous regorafenib administration for patients with liver dysfunction remains to be clarified. PMID:29049226

    Objective: To investigate the clinical value of peri-interventional procedure serum bile acid (TBA) detection in patients with primary liver cancer. Methods: The serum TBA was examined peri-operatively in 160 patients with primary liver cancer for testing the correlations between TBA, liver function, the degree of hepatocirrhosis, interventional therapy method and hepatic failure. Results: The preoperative mean value of serum TBA increased significantly in comparing with that of the control group (P<0.01). The preoperative value of serum TBA in different Child grading patients with primary liver cancer were different significantly (P<0.01), Child A< Child B< Child C, the increased degree of serum TBA corresponded with Child grading of the liver function and the cirrhotic degree of liver. In patients with liver function of Child B and C, the postoperative mean values of serum TBA in different interventional therapy methods were different significantly (P<0.01). Comparing with that of the patients without hepatic failure, the postoperative value of serum TBA in the patients with hepatic failure increased significantly (P<0.01). Conclusions: The value of serum TBA can sensitively and accurately reflect liver reserve ability and damage degree of peri-interventional procedure liver function. Hepatic failure can be detected in time and the prognosis of the patients with primary liver cancer can be predicted by testing the value of serum TBA continually. (authors)

    CT is useful in the evaluation of patients with newly diagnosed or highly suspected lung cancer. The principal role of CT is to screen those patients with metastatic disease beyond the hili from an attempt at curative thoracotomy. While CT is regarded as very sensitive, it is not considered highly specific, and thus a surgical procedure is usually recommended for definitive diagnosis of most ''positive'' CT findings. However, the authors demonstrate a few characteristic CT findings that are highly predictive of unresectable metastatic disease. These CT findings include massive mediastinal lymphadenopathy, diffuse mediastinal infiltration, pericardial involvement, vascular encasement, and advanced chest wall invasion

    To explore recent trends, modes of diagnosis, ethnic distribution and the mortality to incidence ratio of primary liver cancer by subtypes in England and Wales. We obtained incidence (1979-2008) and mortality (1968-2008) data for primary liver cancer for England and Wales and calculated age-standardised incidence and mortality rates. Trends in age-standardised mortality (ASMR) and incidence (ASIR) rates and basis of diagnosis of primary liver cancer and subcategories: hepatocellular carcinoma, intrahepatic bile duct and unspecified liver tumours, were analysed over the study period. Changes in guidelines for the diagnosis of primary liver cancer (PLC) may impact changing trends in the rates that may be obtained. We thus explored changes in the mode of diagnosis as reported to cancer registries. Furthermore, we examined the distribution of these tumours by ethnicity. Most of the statistical manipulations of these data was carried out in Microsoft excel® (Seattle, Washington, United Sttaes). Additional epidemiological statistics were done in Epi Info software (Atlanta, GA, United Sttaes). To define patterns of change over time, we evaluated trends in ASMR and ASIR of PLC and intrahepatic bile duct carcinoma (IHBD) using a least squares regression line fitted to the natural logarithm of the mortality and incidence rates. We estimated the patterns of survival over subsequent 5 and 10 years using complement of mortality to incidence ratio (1-MIR). Age-standardised mortality rate of primary liver cancer increased in both sexes: from 2.56 and 1.29/100000 in 1968 to 5.10 and 2.63/100000 in 2008 for men and women respectively. The use of histology for diagnostic confirmation of primary liver cancer increased from 35.7% of registered cases in 1993 to plateau at about 50% during 2005 to 2008. Reliance on cytology as a basis of diagnosis has maintained a downward trend throughout the study period. Although approximately 30% of the PLC registrations had information on

    Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer an...

    Molecular profiling of primary tumors may facilitate the classification of patients with cancer into more homogenous biological groups to aid clinical management. Metabolomic profiling has been shown to be a powerful tool in characterizing the biological mechanisms underlying a disease but has not been evaluated for its ability to classify cancers by their tissue of origin. Thus, we assessed metabolomic profiling as a novel tool for multiclass cancer characterization. Global metabolic profiling was employed to identify metabolites in paired tumor and non-tumor liver (n=60), breast (n=130) and pancreatic (n=76) tissue specimens. Unsupervised principal component analysis showed that metabolites are principally unique to each tissue and cancer type. Such a difference can also be observed even among early stage cancers, suggesting a significant and unique alteration of global metabolic pathways associated with each cancer type. Our global high-throughput metabolomic profiling study shows that specific biochemical alterations distinguish liver, pancreatic and breast cancer and could be applied as cancer classification tools to differentiate tumors based on tissue of origin.

    Full Text Available Abstract Background Non-alcoholic fatty liver disease (NAFLD has a prevalence of over 20% in Western societies. Affected individuals are at risk of developing both cirrhosis and hepatocellular cancer (HCC. Presently there is no cost effective population based means of identifying cirrhotic individuals and even if there were, our ability to perform HCC surveillance in the at risk group is inadequate. We have performed a pilot proteomic study to assess this as a strategy for serum biomarker detection. Methods 2D Gel electrophoresis was performed on immune depleted sera from 3 groups of patients, namely those with (1 pre-cirrhotic NAFLD (2 cirrhotic NAFLD and (3 cirrhotic NAFLD with co-existing HCC. Five spots differentiating at least one of these three groups were characterised by mass spectroscopy. An ELISA assay was optimised and a cross sectional study assessing one of these serum spots was performed on serum from 45 patients with steatohepatitis related cirrhosis and HCC and compared to 77 patients with histologically staged steatohepatitis. Results Four of the spots identified were apolipoprotein isoforms, the pattern of which was able to differentiate the three groups. The 5th spot, seen in the serum of cirrhotic individuals and more markedly in those with HCC, was identified as CD5 antigen like (CD5L. By ELISA assay, although CD5L was markedly elevated in a number of cirrhotic individuals with HCC, its overall ability to distinguish non-cancer from cancer individuals as determined by AUC ROC analysis was poor. However, serum CD5L was dramatically increased, independently of age, sex, and the presence of necroinflammation, in the serum of individuals with NAFLD cirrhosis relative to those with pre-cirrhotic disease. Conclusion This novel proteomic strategy has identified a number of candidate biomarkers which may have benefit in the surveillance and diagnosis of individuals with chronic liver disease and/or HCC.

    Full Text Available Undetected micrometastasis plays a key role in the metastasis of cancer in colorectal cancer (CRC patients. The aim of this study is to identify a biomarker of CRC patients with liver metastasis through the detection of circulating tumor cells (CTCs. Microarray and bioinformatics analysis of 10 CRC cancer tissue specimens compared with normal adjacent tissues revealed that 31 genes were up-regulated (gene expression ratio of cancer tissue to paired normal tissue > 2 in the cancer patients. We used a weighted enzymatic chip array (WEnCA including 31 prognosis-related genes to investigate CTCs in 214 postoperative stage I–III CRC patients and to analyze the correlation between gene expression and clinico-pathological parameters. We employed the immunohistochemistry (IHC method with polyclonal mouse antibody against DVL1 to detect DVL1 expression in 60 CRC patients. CRC liver metastasis occurred in 19.16% (41/214 of the patients. Using univariate analysis and multivariate proportional hazards regression analysis, we found that DVL1 mRNA overexpression had a significant, independent predictive value for liver metastasis in CRC patients (OR: 5.764; 95% CI: 2.588–12.837; p < 0.0001 on univariate analysis; OR: 3.768; 95% CI: 1.469–9.665; p = 0.006 on multivariate analysis. IHC staining of the immunoreactivity of DVL1 showed that DVL1 was localized in the cytoplasm of CRC cells. High expression of DVL1 was observed in 55% (33/60 of CRC tumor specimens and was associated significantly with tumor depth, perineural invasion and liver metastasis status (all p < 0.05. Our experimental results demonstrated that DVL1 is significantly overexpressed in CRC patients with liver metastasis, leading us to conclude that DVL1 could be a potential prognostic and predictive marker for CRC patients.

    Hepatitis C is the most common health problem worldwide and is major cause of death due to proliferation of hepatocellular carcinoma. The medicines available for HCV treatment overcome up-to 95% complications of HCV. However, liver cancer needs some additional care. Normally Sorafenib tosylate 200 mg is recommended for liver cancer. There is no such trial in which this drug could effectively be used in combination of direct acting antivirals for HCV. The study was conducted for HCV patients (n=30) with liver cancer having decompensated stage. Combination of Sorafenib tosylate, Ribavirn and Sofosbuvir were used for the pharmacokinetics of these medicines. Child pugh score less then 7 (CP A) in adults during treatment phase (received 12 weeks of Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir 400 mg once daily) have no side effect while child pugh score 7-9 (CP B) have evidence of hypertension. The main efficiency end point sustained virology response with overcoming liver cancer as well in 12 weeks after end treatment (SVR-LLC 12). Mean pharmacokinetic exposure to Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir at week 8th was 2.1, 1.5,1.2 times greater in CP B than in CP A. Adverse effects (AEs) were observed in 12 out of 30 patients but not severe as lethal for life. Treatment with Sorafenib tosylate, Ribavirn and Sofosbuvir for twelve weeks was harmless and well accepted, 100 % patients achieve (SVR LLC 12) with 10-fold cure rate more than previous ones. The combination therapy of Sorafenib tosylate, Ribavirn and Sofosbuvir was found helpful for the management of decompensated liver cancer.

    Objective: To investigate prospectively the apparent diffusion coefficient (ADC)in evaluating the capability of diffusion-weighted imaging (DWI) technique for detecting viable tumor tissue after transarterial chemoembolization (TACE) of liver cancer. Methods: Institutional review board approval was obtained, and all patients were provided with informed consent. DWI, enhanced CT and DSA examinations were performed in 16 patients with liver cancer after TACE. Qualitative evaluations of the capability for detecting the remaining or recurrent viable tumor with DWI were performed by comparing enhanced-CT and DSA. ADCs and maximum CT enhancement value(HU) were measured(in 14 of the 16 patients)for lesions after TACE. And their relationships were investigated by comprehension correlative analysis. Results: Liver cancer after TACE presented variable signal intensities on DWI. The homogeneous accumulation of iodized oil observed on CT in 2 of 16 patients with liver cancer after TACE showed no tumor stain observed on DSA but with corresponding homogeneous hypointensity on DWI. The partial defects shown in accumulation of iodized oil in 2 of 16 patients represented the tumor stain on DSA corresponding to hyperintensities on DWI. None or faint accumulation of iodized oil areas in 12 of all patients, showed striking tumor stains corresponding to hyperintensities on DWI, and tumor necrosis had none or sight tumor stain on DSA, corresponding to hypointensities on DWI. A correlation between ADCs and maximum CT enhancement value (HU) of lesions after TACE was found (r=-0.76490, <0.05). Conclusion: Diffusion MRI is an useful method for detecting tumor remnant or recurrence of liver cancer after TACE, and can be used for the follow-up. (authors)

    Methyleugenol (MEG), a constituent of plants used in the human diet, is hepatocarcinogenic in rodents. In an experiment to elucidate its mode of action in rat liver, male F344 rats were administered MEG intragastrically at 3 doses per week for up to 16 weeks in an initiation phase, after which half the rats were fed 500 ppm phenobarbital (PB) in the diet to promote liver neoplasia and the other half were maintained on control diet for 24 weeks. At 8 and 16 week interim terminations, (32)P-nucleotide postlabeling assay revealed 3 adducts in livers of all MEG groups. The hepatocellular replicating fractions, measured by proliferating cell nuclear antigen immunohistochemistry, were doubled or more in all MEG groups. Hepatocellular altered foci, detected by glutathione S-transferase-placental type (π) immunohistochemistry, were present beginning with the high dose group at 8 weeks and extending to all MEG groups at 16 weeks. At the end of maintenance/promotion phase, the incidences, multiplicity and size of foci was similar between control and low dose groups, while those of mid and high dose groups were increased. Hepatocellular adenomas occurred in the mid and high dose groups, attaining higher multiplicity and size with PB. Thus, MEG had rapid initiating activity, reflecting the formation of DNA adducts and possibly cell proliferation. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available The patient was a 68-year-old man who was admitted to our hospital with a liver tumor. Abdominal ultrasonography and computed tomography revealed a liver tumor 30 mm in diameter. On colonoscopy, a pedunculated tumor with a central depression (20 mm in diameter was observed in the ascending colon, and this tumor was considered to be invading deeply into the submucosal layer. Right hemicolectomy with D3 lymphadenectomy and partial hepatectomy were performed simultaneously. On histopathological examination of the resected specimen, the tumor was a well-differentiated tubular adenocarcinoma with 3,000 μm invasion of the submucosal layer. The liver tumor showed histological findings similar to those of the primary colorectal carcinoma. The pathological stage according to the 7th edition of the TNM classification was stage IV (T1N0M1. Nine months after the operation, computed tomography revealed hepatic hilar lymph node metastases and a great deal of ascites. The patient ultimately died 14 months after the operation.

    Purpose: To determine whether high-dose radiation leads to improved outcomes in patients with non-small-cell lung cancer (NSCLC). Methods and Materials: This analysis included 106 patients with newly diagnosed or recurrent Stages I-III NSCLC, treated with 63-103 Gy in 2.1-Gy fractions, using three-dimensional conformal radiation therapy (3D-CRT) per a dose escalation trial. Targets included the primary tumor and any lymph nodes ≥1 cm, without intentionally including negative nodal regions. Nineteen percent of patients (20/106) received neoadjuvant chemotherapy. Patient, tumor, and treatment factors were evaluated for association with outcomes. Estimated median follow-up was 8.5 years. Results: Median survival was 19 months, and 5-year overall survival (OS) was 13%. Multivariate analysis revealed weight loss (p = 0.011) and radiation dose (p = 0.0006) were significant predictors for OS. The 5-year OS was 4%, 22%, and 28% for patients receiving 63-69, 74-84, and 92-103 Gy, respectively. Although presence of nodal disease was negatively associated with locoregional control under univariate analysis, radiation dose was the only significant predictor when multiple variables were included (p = 0.015). The 5-year control rate was 12%, 35%, and 49% for 63-69, 74-84, and 92-103 Gy, respectively. Conclusions: Higher dose radiation is associated with improved outcomes in patients with NSCLC treated in the range of 63-103 Gy

  10. Guide to intra-arterial infusion chemotherapy for pancreatic cancers (draft text)

    International Nuclear Information System (INIS)

    2012-01-01

    Pancreatic cancer is one of most malignant solid tumors. Trans-arterial infusion chemotherapy has been used for the inoperable pancreatic cancers. The local drug concentration in intra-arterial infusion chemotherapy is much higher than that in intravenous chemotherapy. Thus, a better therapeutic effect can be surely achieved, the disease-related symptoms can be well improved, the patient's survival time can be markedly prolonged, and the liver metastases can be effectively reduced. This paper aims to suggest a more detailed and standardized therapeutic scheme to perform intra-arterial infusion chemotherapy for inoperable pancreatic cancers, focusing on the relevant concept, contraindications, indications, preoperative preparation, methods of operation, postoperative treatment, the prevention and treatment of complications, etc. The scheme will help domestic interventional physicians to make reasonable decisions in their clinical practice. Of course, the scheme proposed here is not a mandatory standard, and it can not resolve all the problems which might be encountered in employing intra-arterial infusion chemotherapy for patients with inoperable pancreatic cancer. Therefore, the interventional physicians should fully understand the most useful medical evidence of a given patient and sincerely take the patient's own will into consideration before an individualized and reasonable therapeutic plan is able to be worked out.

    To describe and analyze the charecteristics and trends of liver cancer mortality during the past fifty years in Qidong, China. Retrospective mortality survey was conducted to get the data on liver cancer death in the period of 1958-1971, and the data from 1972 to 2007 were obtained from the records of cancer registration in Qidong. The crude mortality rate (CR) of liver cancer, and age-standardized rate by Chinese population (CASR) and by world population (WASR) were calculated and analyzed. The total percent changes (PC) and annual percent changes (APC) were used for evaluating the increasing trends of the mortality. The sex-specific rate, age-specific rate, truncated rate of the age group 35 - 64, cumulative rate of the age group 0-74, cumulative risk, period-rate, and the rate for age-birth cohort were compared. The natural death rate in Qidong residents for the past five-decade period experienced a wave interval of 8.62‰ in 1958 down to 5.37‰ in 1979, and up to 7.75‰ in 2007. The mortality rate for all-site cancers was increased from 56.69 per 100, 000 to 234.97 per 100, 000. The mortality rate of liver cancer, being 20.45 per 100, 100 in 1958 was increased to 49.04 per 100, 000 in 1972, and up to 69.29 per 100, 000 in 2007. According to the registration data of 1972 - 2007, the death from liver cancer was accounted for 34.88% of all deaths due to cancers, with a CR of 58.86 per 100, 000, CASR of 38.36 per 100, 000, and WASR, 49.37 Per 100, 000 in Qidong. The truncated rate for the age group 35 - 64 was 117.08 per 100, 000, and the cumulative rate for the age group 0-74 and the cumulative risk were 5.15% and 5.02%, respectively. The CRs for males was 90.52 per 100, 000 and for females was 27.93 per 100, 000, with a sex ratio of 3.24:1. For the period of 1972 - 2007, the PC for CR was 49.71%, and APC was +1.41%, showing an increasing variation tendency. The APCs for CASR and WASR, however, were decreasing, with a percentage of -1.11%, and -0

    Purpose: To describe efficacy and safety of stereotactic body radiation therapy (SBRT) for the treatment of inoperable hepatocellular carcinoma. Methods: The records of 77 consecutive patients treated with SBRT for 97 liver-confined HCC were reviewed. A total dose of 45 Gy in 3 fractions was prescribed to the 80% isodose line. Local control (LC), overall survival (OS), progression-free survival (PFS) and toxicity were studied. Results: The median follow-up was 12 months. The median tumor diameter was 2.4 cm. The LC rate was 99% at 1 and 2 years. The 1 and 2-year OS were 81.8% and 56.6% respectively. The median time to progression was 9 months (0–38). The rate of hepatic toxicity was 7.7% [1.6–13.7], 14.9% [5.7–23.2] and 23.1% [9.9–34.3] at 6 months, 1 year and 2 years respectively. In multivariate analysis, female gender (HR 7.87 [3.14–19.69]), a BCLC B-C stage (HR 3.71 [1.41–9.76]), a sum of all lesion diameters ⩾2 cm (HR 7.48 [2.09–26.83]) and a previous treatment (HR 0.10 [0.01–0.79]) were independent prognostic factors of overall survival. Conclusion: SBRT allows high local control for inoperable hepatocellular carcinomas. It should be considered when an ablative treatment is indicated in Child A patients

    We report 2 cases of laparoscopic surgery for patients who had liver abscess as the initial manifestation of underlying colon cancer. The first case was in an 80-year-old woman who presented to our hospital with a diagnosis ofliver abscess. Percutaneous transhepatic abscess drainage(PTAD)was performed as initial treatment. Subsequent colonoscopy revealed a type 1 tumor in the cecum, and biopsy results ofthe mass indicated adenocarcinoma. The patient underwent laparoscopic right hemicolectomy as curative treatment. The pathological findings were as follows: tub1, T2, N0, M0 and Stage I . Two years later, she remains disease free. The second case was in a 59-year-old man with liver abscess. Colonoscopy also revealed a type 2 tumor in the sigmoid colon. After treatment of the liver abscess with PTAD, laparoscopic sigmoidectomy was performed with a preoperative diagnosis of sigmoid colon cancer. The pathological findings were as follows: tub2, T3, N0, M0 and Stage II . Lung metastases appeared 10 months after surgery, and systemic chemotherapy was administered. In conclusion, liver abscess is occasionally caused by malignancy, and complete gastrointestinal evaluation should be conducted. Laparoscopic radical surgery can be safely performed in cases in which the liver abscesses are controlled.

    Plant Technical Specifications are issued by the US NRC to ensure that safe nuclear power plant operation is maintained within the assumptions for parameters and Structures, Systems, and Components (SSCs) made in the plant safety analysis reports. The Technical Specifications are made up of Limiting Conditions for Operation (LCOs), which are the minimum set of requirements that must be met based on the assumptions of the safety analysis, Actions, which are the remedial or compensatory actions that must be taken if the LCO is not met, and Surveillance Requirements, that demonstrate that the LCO is met. The Technical Specification Actions contain Completion Times (CTs) which are the time within which remedial actions must be taken, in the event that the LCO is not met. The Improved Standard Technical Specifications (ISTS) for Westinghouse plants are contained in NUREG-1431, Revision 2. Condition A of Technical Specification 3.5.2 (ECCS- Operating) in NUREG-1431, Revision 2, allows components to be taken out of service for up to 72 hours, as long as 100% of the ECCS flow equivalent to a single Operable ECCS train exists. Condition A would allow, for example, the A train low head safety injection (LHSI) and the B train high head safety injection (HHSI) pumps to be taken out of service (for 72 hours) as long as it could be demonstrated that the remaining components could provide 100% train equivalent flow capacity. The 'cross-training' allowed by this Condition in the ISTS provides flexibility when performing routine pre-planned preventive maintenance and testing, as well as during emergent corrective maintenance and testing associated with random component inoperabilities. Without this flexibility, a unit would have to initiate a plant shutdown within 1 hour, if component(s) were inoperable in different trains. In order to implement this flexibility, the various combinations of components in opposite trains must be evaluated to determine whether 100% of the ECCS flow

    A microbeam synchrotron X-ray fluorescence (μSRXRF) technique has been used to determine the localization and the relative concentrations of Zn, Cu, Fe and Ca in primary colorectal cancer and secondary colorectal liver metastases. 24 colon and 23 liver samples were examined, all of which were formalin fixed tissues arranged as microarrays of 1.0 mm diameter and 10 μm thickness. The distribution of these metals was compared with light transmission images of adjacent sections that were H and E stained to reveal the location of the cancer cells. Histological details were provided for each sample which enable concentrations of all elements in different tissue types to be compared. In the case of liver, significant differences have been found for all elements when comparing tumour, normal, necrotic, fibrotic, and blood vessel tissues (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have also been found to be significantly different among tumour, necrotic, fibrotic, and mucin tissues in the colon samples (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have been compared between primary colorectal samples and colorectal liver metastases. Concentration of Zn, Cu, Fe and Ca are higher in all types of liver tissues compared to those in the colon tissues. Comparing liver tumour and colon tumour samples, significant differences have been found for all elements (Mann Whitney, P<0.0001). For necrotic tissues, significant increase has been found for Zn, Ca, Cu and Fe (Mann Whitney, P<0.0001 for Fe and Zn, 0.014 for Ca, and 0.001 for Cu). The liver fibrotic levels of Zn, Ca, Cu and Fe were higher than the fibrotic colon areas (independent T test, P=0.007 for Zn and Mann Whitney test P<0.0001 for Cu, Fe and Ca). For the blood vessel tissue, the analysis revealed that the difference was only significant for Fe (P=0.009) from independent T test.

    Mixed anti-alpha-fetoprotein monoclonal antibodies (AFPMcAb) labeled with 131 I were used in the treatment of 23 patients of moderate to advanced primary liver cancer. In 16 cases treated with 24 doses, the survival periods were 18-605 days with a mean of 135 days. Two patients with moderately advanced liver cancer had a mean survival period of 465 days. According to our experience, the larger dose of 131 I and of anti-AFPMcAb, the longer the survival period and the better the therapeutic results were observed. The relationship between the ratio of cancer/liver radioactivity and the survival period remains to be elucidated

    Full Text Available ObjectiveTo compare the age distributions and presence of hepatitis B virus (HBV serological markers between primary hepatic cancer (PHC patients with and without liver cirrhosis. MethodsA total of 547 PHC cases were analyzed retrospectively. After dividing into two groups according to liver cirrhosis status, the between-group differences in age and HBV serological markers, such as hepatitis B e antigen (HBeAg status, were statistically compared using the Chi-squared test. ResultsThe number of cirrhotic and non-cirrhotic PHC patients was 265 and 282, respectively. HBV infection was present in 221 cirrhotic PHC patients and 256 non-cirrhotic PHC patients (834% vs. 90.8%. There was a substantial bias in the proportion of males to females in the cirrhotic PHC patients (7.83∶1. The number of PHC patients <60 years old was similar between the cirrhotic and non-cirrhotic groups, but the non-cirrhotic group had significantly more patients >60 years old (P<0.005. In cirrhotic PHC patients, the HBV infection rate was highest in the <40 years old age group (96.7% and the HBeAg serological conversion rate was highest in the 40-60 years old age group (89.5%. In non-cirrhotic PHC patients, the 40-60 years old age group showed the highest HBV infection rate (90.3% but the lowest HBeAg serological conversion rate (80.0%. ConclusionPHC with liver cirrhosis mainly occurred in males, with the HBV infection rate being higher in individuals <60 years old. Non-cirrhotic PHC patients were more often >60 years old. Many of the HBV-infected PHC patients with cirrhosis had high HBeAg serological conversion rate.

    There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.

    The prognosis of hepatocellular carcinoma (HCC) varies following surgical resection and the large variation remains largely unexplained. Studies have revealed the ability of clinicopathologic parameters and gene expression to predict HCC prognosis. However, there has been little systematic effort to compare the performance of these two types of predictors or combine them in a comprehensive model. Tumor and adjacent non-tumor liver tissues were collected from 272 ethnic Chinese HCC patients who received curative surgery. We combined clinicopathologic parameters and gene expression data (from both tissue types) in predicting HCC prognosis. Cross-validation and independent studies were employed to assess prediction. HCC prognosis was significantly associated with six clinicopathologic parameters, which can partition the patients into good- and poor-prognosis groups. Within each group, gene expression data further divide patients into distinct prognostic subgroups. Our predictive genes significantly overlap with previously published gene sets predictive of prognosis. Moreover, the predictive genes were enriched for genes that underwent normal-to-tumor gene network transformation. Previously documented liver eSNPs underlying the HCC predictive gene signatures were enriched for SNPs that associated with HCC prognosis, providing support that these genes are involved in key processes of tumorigenesis. When applied individually, clinicopathologic parameters and gene expression offered similar predictive power for HCC prognosis. In contrast, a combination of the two types of data dramatically improved the power to predict HCC prognosis. Our results also provided a framework for understanding the impact of gene expression on the processes of tumorigenesis and clinical outcome

    Chronic hepatitis B and hepatitis C virus (HBV and HCV) infections are among the leading causes of preventable death worldwide. Chronic viral hepatitis is the cause of most primary liver cancer, which is the third leading cause of cancer deaths globally and the ninth leading cause of cancer deaths in the United States. The extent to which comprehensive cancer control (CCC) programs in states, tribal governments and organizations, territories, and Pacific Island jurisdictions address chronic hepatitis B and/or hepatitis C infections as risk factors for liver cancer or recommend interventions for liver cancer prevention in their CCC plans remains unknown. We searched CCC plans for this information using the search tool at http://www.cdc.gov/cancer/ncccp/ to access the content of plans for this information. A combination of key search terms including "liver cancer", "hepatitis", "chronic alcohol", and "alcohol abuse" were used to identify potential content regarding liver cancer risk factors and prevention. Relevant content was abstracted for further review and classification. Of 66 (Although CDC funds 65 programs, one of the Pacific Island Jurisdiction grantees is the Federated States of Micronesia (FSM). This national program supports four FSM states, each of which submits a cancer plan to CDC for a total of 69 plans. During this time period, 66 plans were available on the website.) CCC plans, 27% (n = 18) addressed liver cancer using the above-mentioned search terms. In the 23 plans that addressed HBV and/or HCV, there were 25 goals, objectives, strategies, and outcomes aimed at reducing the incidence or prevalence of HBV and/or HCV infection. While nearly a third of CCC programs identify at least one goal, objective, strategy, outcome, or prevention program to reduce cancer burden in their CCC plans, few plans discuss specific actions needed to reduce the burden of liver cancer.

    Full Text Available Poor prognosis of hepatocellular carcinoma (HCC associated with late diagnosis necessitates the development of early diagnostic biomarkers. We have previously delineated the landscape of DNA methylation in HCC patients unraveling the importance of promoter hypomethylation in activation of cancer- and metastasis-driving genes. The purpose of the present study was to test the feasibility that genes that are hypomethylated in HCC could serve as candidate diagnostic markers. We use high resolution melting analysis (HRM as a simple translatable PCR-based method to define methylation states in clinical samples. We tested seven regions selected from the shortlist of genes hypomethylated in HCC and showed that HRM analysis of several of them distinguishes methylation states in liver cancer specimens from normal adjacent liver and chronic hepatitis in the Shanghai area. Such regions were identified within promoters of neuronal membrane glycoprotein M6-B (GPM6B and melanoma antigen family A12 (MAGEA12 genes. Differences in HRM in the immunoglobulin superfamily Fc receptor (FCRL1 separated invasive tumors from less invasive HCC. The identified biomarkers differentiated HCC from chronic hepatitis in another set of samples from Dhaka. Although the main thrust in DNA methylation diagnostics in cancer is on hypermethylated genes, our study for the first time illustrates the potential use of hypomethylated genes as markers for solid tumors. After further validation in a larger cohort, the identified DNA hypomethylated regions can become important candidate biomarkers for liver cancer diagnosis and prognosis, especially in populations with high risk for HCC development.

    Changes in lipid metabolism have been associated with tumor promotion in rat liver. Similarities and differences of lipid parameters were investigated using the mycotoxin fumonisin B1 (FB1) and the 2-acetylaminofluorene/partial hepatectomy (AAF/PH) treatments as cancer promoters in rat liver. A typical lipid phenotype was observed, including increased membranal phosphatidylethanolamine (PE) and cholesterol content, increased levels of C16:0 and monounsaturated fatty acids in PE and phosphatidylcholine (PC), as well as a decrease in C18:0 and long-chained polyunsaturated fatty acids in the PC fraction. The observed lipid changes, which likely resulted in changes in membrane structure and fluidity, may represent a growth stimulus exerted by the cancer promoters that could provide initiated cells with a selective growth advantage. This study provided insight into complex lipid profiles induced by two different cancer promoting treatments and their potential role in the development of hepatocyte nodules, which can be used to identify targets for the development of chemopreventive strategies against cancer promotion in the liver.

    Full Text Available Liver cancer is one of the most fatal cancers worldwide, the management of which demands a multidisciplinary approach. Conventional therapies such as surgery, chemotherapy, and radiotherapy have gained reasonable success. However, most of these patients experience a severe torment, both mentally and physically. Numerous studies have indicated that traditional Chinese medicine (TCM, when used in conjunction with conventional allopathic therapies, can enhance their efficacy and diminish the resulting side effects and complications. Therefore, a deeper understanding of TCM is of immense help to physicians and other health care providers in providing a better care to patients. TCM is proved to be efficacious in terms of suppressing tumor progression, improving immune system function, and increasing the sensitivity to chemo- and radio-therapies. Although TCM can be delivered in various dosage forms, pills, decoctions, and injections are the three most commonly used forms in treating liver cancer. While these traditional dosage forms limits the usage of herbal medicines to their full potential novel TCM delivery forms such as nanoparticles can enhance the bioavailability, reduce any associated side effect, achieve targeted delivery, and improve the acceptance of TCM by patients. This review summarizes the current application of TCM in different prescriptions and dosage forms in the treatment of liver cancer, along with their advantages and disadvantages, all of which is believed to contribute to better understanding of Chinese herbal medicines as an essential part in the treatment of liver cancer and the importance of this trend to combine TCM and western medicine in novel dosage forms for a better management of the condition.

    Although dietary patterns, specific foods, and their constituents have been linked to cancer risk, the role of dietary patterns and specific food groups in liver cancer risk has not been investigated. In the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS), two cohort studies of 132 837 Chinese women and men, we evaluated the relationship between dietary patterns, food groups, and liver cancer risk. Through in-person interviews, dietary information intake over the preceding year was collected by using a validated food-frequency questionnaire. Cox regression model was used to estimate hazard ratios and 95% confidence intervals with adjustment for potential confounders. During an average follow-up of 10.9 (SWHS) or 5.5 (SMHS) years, 267 incident liver cancer cases were identified after the first 2 years of study enrolment. Three dietary patterns were derived by factor analysis. A vegetable-based dietary pattern was inversely associated with liver cancer; hazard ratios (95% confidence intervals) for the lowest to highest quartiles were: 1.00; 0.98 (0.71-1.35); 0.93 (0.67-1.29); and 0.58 (0.40-0.84); P(trend) = 0.01. The association was stronger among participants with a history of chronic liver disease. Further analyses showed high intakes of celery, mushrooms, allium vegetables, composite vegetables (including asparagus lettuce and garland chrysanthemum), legumes and legume products were associated with reduced liver cancer risk (all P(trend) < 0.05). Fruit- and meat-based dietary patterns were not associated with liver cancer risk. Our study suggests that a vegetable-based dietary pattern is associated with reduced liver cancer risk. © 2013 Japanese Cancer Association.

    Full Text Available Introduction. Colorectal cancer is one of the most frequent cancers in the world and liver metastases are seen in up to 19% of patients with colorectal cancers. Detection of liver metastases is not only vital for sufficient treatment and survival, but also for a better estimation of prognosis. The aim of this study was to evaluate the feasibility of diffusion weighted MRI of the liver as part of a combined MR evaluation of patients with rectal cancers and compare it with the standard preoperative evaluation of the liver with CT.Methods. Consecutive patients diagnosed with rectal cancers were asked to participate in the study. Preoperative CT and diffusion weighted MR (DWMR were compared to contrast enhanced laparoscopic ultrasound (CELUS.Results. A total of 35 patients were included, 15 patients in Group-1 having the standard CT evaluation of the liver and 20 patients in Group-2 having the standard CT evaluation of the liver and DWMR of the liver. Compared with CELUS, the per-patient sensitivity/specificity was 50/100% for CT, and for DWMR: 100/94% and 100/100% for Reader 1 and 2, respectively. The per-lesion sensitivity of CT and DWMR were 17% and 89%, respectively compared with CELUS. Furthermore, one patient had non-resectable metastases after DWMR despite being diagnosed with resectable metastases after CT. Another patient was diagnosed with multiple liver metastases during CELUS, despite a negative CT-scan.Discussion. DWMR is feasible for preoperative evaluation of liver metastases. The current standard preoperative evaluation with CT-scan results in disadvantages like missed metastases and futile operations. We recommend that patients with rectal cancer, who are scheduled for MR of the rectum, should have a DWMR of the liver performed at the same time.

    The aim of this study is to assess the role of contrast-enhanced ultrasonography (CEUS) in the detection of liver metastases in cancer patients with geographic liver fatty deposition on greyscale ultrasonography (US). Thirty-seven consecutive cancer patients (24 women and 13 men; age, 33 to 80 years; mean, 58.1 years) with geographic liver fatty deposition, but without any detectable focal liver lesion on greyscale US, underwent sulphur hexafluoride-enhanced US. Two readers reported by consensus the presence, size, and location of any detected lesion. All patients underwent magnetic resonance imaging (MRI) as a confirmatory study. Sensitivity, specificity, positive and negative predictive values (PPV and NPV), and accuracy were calculated. Seven focal liver lesions (size, 4 to 10 mm; mean, 6.1 mm) were detected in 4/37 patients (10.8%): four metastases (size, 5 to 10 mm; mean, 6.7 mm) were detected both by CEUS and MRI, with one hemangioma and two cysts (size range, 4 to 6 mm; mean, 5.3 mm) detected by MRI only. In 1/37 patients (2.7%), CEUS misdiagnosed geographic fatty change as three metastases. In 32/37 patients (86.5%), no lesions were detected. Sensitivity, specificity, PPV, NPV, and accuracy of CEUS were 100% (95% confidence Interval [CI], 1.000 to 1.000), 97.1% (95% CI, 0.914 to 1.027), 75%, 100%, and 97.3%, respectively. No statistically significant differences were found between CEUS and MRI in the detection of focal liver lesions (P=0.480), whereas both of them performed better than baseline US (P<0.001). CEUS improves the detection of liver metastases in cancer patients with geographic liver fatty deposition on greyscale US

    Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes. PMID:25058762

    Molecular imaging based on reporter gene expression allows tissue-specific events or processes to be measured using the bioluminescence imaging (BLI) reporter gene expression vector controlled by specific enhancer/promoters. Alpha-fetoprotein (AFP), which is a tumor marker, is a serum glycoprotein that is expressed normally by fetal liver and yolk-sac cells, as well as in trace amounts in the fetal gastrointestinal tract. The serum concentration of AFP decreases rapidly after birth and its expression is repressed in adults. Approximately 80% of HCC patients show an increase in the AFP level. Therefore, AFP has been used for many years as a diagnostic and prognostic serum marker for HCC and transgenic system for AFP was proposed as a valuable tool for elucidation of mechanism of transcriptional regulation during liver development and hepatocarcinogenesis. In this study, firefly luciferase (fLuc) expressing transgenic mice controlled by the AFP enhancer/ promoter (enh/promoter) were produced to screen for the development of AFP-producing liver cancer. These models are expected to be useful for monitoring agents or drugs that modulate the AFP level as well as for measuring the specific signaling events important for liver cancer development

    This study attempts to judge the reliability of scintigraphy in the diagnosis of liver cancers. It concerns 54 observations with anatomical confrontation (laparoscopy, biopsy, laparotomy and/or autopsy). Technetium 99m scintigraphy gives a correct diagnosis in 81.5% of the cases, whether cirrhosis is present or not. Scintigraphy is only one stage in the investigation of neoplasic liver disease. This study shows that all too often it is practised alone since of 201 observations only 54 include another examination, and of these only 21 a laparoscopy. The simultaneous use of scintigraphy and laparoscopy eliminates false positives and reduces the percentage of false negatives from 7.5% to 4%. The two methods combined are therefore reliable to 96% (i.e. 96% of successful diagnosis in liver cancer tests. This work was performed with the techniques available in 1973. The quality of the scintigraphic image should be improved by technical progress in the form of new isotopic products, cameras with better definition and computerized data processing. With these new techniques it will certainly be possible to detect very small lacunae and to observe in more detail their diffusion in the liver parenchyma [fr

    2008-01-01

    Recombinant human adenovirus p53 (Ad-p53)injection has been used for treating tumors in combination with several local therapeutic methods. Taking liver cancer as an example, this article introduces the combination of Ad-p53 in procedures of interventional therapy. Mechanisms of their effects are emphasized to pursue an optimal synergism in killing tumors. Intratumoral injection is suggested as the first choice of Ad- p53 administration with the least recommended dosage for a single tumor. The optimal time for intervention of liver cancer is supposed to be 2 to 5 days after the administration of Ad-p53. There are several theories on the therapeutic method taking p53 as a target, some of them are contradictional; therefore one has to select either activating or inhibiting the p53 pathway beforehand. For advanced malignancies, the selection should be cautious for appropriater cases from the proper candidates. (authors)

    The World Health Organization offers clear guidance on the development of national cancer control programmes based on a country's level of resources, yet the motivation to implement such programmes may be driven by factors other than resources. To compare stakeholder motivation to implement a national liver cancer control programme and assess if variation in motivation was associated with stakeholder characteristics or with national indicators of need and resources. Relevant stakeholders were purposively selected from 13 countries (Australia, China, France, Germany, Italy, Japan, Nigeria, South Korea, Spain, Taiwan, Thailand, Turkey and USA) to participate in a structured survey on liver cancer control. Respondents included 12 individuals working in clinical, 5 in policy and 3 in advocacy roles from each country. Stakeholders' motivation was measured using a scale grounded in expectancy theory and knowledge gained during previous qualitative interviews. Comparisons across countries and respondent characteristics were conducted using hierarchical regression. Country level motivation scores, holding constant individual level covariates, were correlated with indicators of need and resources and tested using Pearson's correlation coefficients. In total, 260 stakeholders, equally drawn from the study countries, completed the survey (45% response rate). At the national level, motivation was highest in Nigeria, Thailand and China (P motivation was observed among stakeholders working at the international level relative to the local level (P = 0.017). Motivation was positively associated with a country's relative burden of liver cancer (P = 0.015) and negatively associated with their level of resources (P = 0.018). This study provides the first empirical evidence on the motivation of stakeholders to implement national cancer control programmes. Furthermore, we demonstrate that motivation is more clearly associated with a country's cancer control needs rather than resources

Fifty-two female patients underwent surgery for BCLM between 2002 and 2013. Only patients with liver resections (n=43) were included in the analysis. The median survival of the 43 patients with liver resection was 32.2 months. The factors significantly associated with overall post-hepatectomy survival were estrogen/progesteron receptor (ER/PR) status (p=0.002), node involvement of the primary tumor (p=0.049), size (p=0.005) and number (p=0.006) of the metastatic lesions. The 1-, 3- and 5-year survival rates after curative liver resection were 93.02%, 74.42%, 58.14%, respectively. BCLM resection is a safe procedure and offers survival benefit, especially in patients with reduced liver metastatic burden (solitary metastases, diameter of the metastases <5 cm) and positive ER/PR status.

    Full Text Available In patients with colorectal cancer (CRC that metastasizes to the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. Although new therapeutic regimens developed over the past decade have increased survival, there is substantial room for improvement in selecting targeted treatment regimens for the patients who will derive the most benefit. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem of detecting and treating the metastatic spread of CRC to the liver. Our multidisciplinary group held a state-of-the-science symposium this past year to review advances in this rapidly evolving field. Herein, we present a discussion around the issues facing treatment of patients with CRC liver metastases, including the relationship of discrete gene signatures with prognosis. We also discuss the latest advances to maximize regional and systemic therapies aimed at decreasing intrahepatic recurrence, review recent insights into the tumor microenvironment, and summarize advances in noninvasive multimodal biomarkers for early detection of primary and recurrent disease. As we continue to advance clinically and technologically in the field of colorectal tumor biology, our goal should be continued refinement of predictive and prognostic studies to decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailored multidisciplinary approach to cancer care.

    Full Text Available Background & Aims: Circulating tumor DNA (ctDNA carrying tumor-specific sequence alterations has been found in the cell-free fraction of blood. Liver cancer tumor specimens are difficult to obtain, and noninvasive methods are required to assess cancer progression and characterize underlying genomic features. Methods: We analyzed 46 patients with hepatocellular carcinoma who underwent hepatectomy or liver transplantation and for whom whole-genome sequencing data was available. We designed personalized assays targeting somatic rearrangements of each tumor to quantify serum ctDNA. Exome sequencing was performed using cell-free DNA paired primary tumor tissue DNA from a patient with recurrent liver cancer after transcatheter arterial chemoembolization (TACE. Results: We successfully detected ctDNA from 100 μL of serum samples in 7 of the 46 patients before surgery, increasing with disease progression. The cumulative incidence of recurrence and extrahepatic metastasis in the ctDNA-positive group were statistically significantly worse than in the ctDNA-negative group (P = .0102 and .0386, respectively. Multivariate analysis identified ctDNA (OR 6.10; 95% CI, 1.11–33.33, P = .038 as an independent predictor of microscopic vascular invasion of the portal vein (VP. We identified 45 nonsynonymous somatic mutations in cell-free DNA after TACE and 71 nonsynonymous somatic mutations in primary tumor tissue by exome sequencing. We identified 25 common mutations in both samples, and 83% of mutations identified in the primary tumor could be detected in the cell-free DNA. Conclusions: The presence of ctDNA reflects tumor progression, and detection of ctDNA can predict VP and recurrence, especially extrahepatic metastasis within 2 years. Our study demonstrated the usefulness of ctDNA detection and sequencing analysis of cell-free DNA for personalized treatment of liver cancer.

    c-Jun/AP-1 has been linked to invasive properties of aggressive breast cancer. Recently, it has been reported that overexpression of c-Jun in breast cancer cell line MCF-7 resulted in increased AP-1 activity, motility and invasiveness of the cells in vitro and tumor formation in nude mice. However, the role of c-Jun in metastasis of human breast cancer in vivo is currently unknown. To further investigate the direct involvement of c-Jun in tumorigenesis and metastasis, in the present study, the effects of c-Jun overexpression were studied in both in vitro and in nude mice. Ectopic overexpression of c-Jun promoted the growth of MCF-7 cells and resulted in a significant increase in the percentage of cells in S phase and increased motility and invasiveness. Introduction of c-Jun gene alone into weakly invasive MCF-7 cells resulted in the transfected cells capable of metastasizing to the nude mouse liver following tail vein injection. The present study confirms that overexpression of c-Jun contributes to a more invasive phenotype in MCF-7 cells. It indicates an interesting relationship between c-Jun expression and increased property of adhesion, migration and in vivo liver metastasis of MCF-7/c-Jun cells. The results provide further evidence that c-Jun is involved in the metastasis of breast cancer. The finding also opens an opportunity for development of anti-c-Jun strategies in breast cancer therapy

    We fabricated a spheroid-forming unit (SFU) for efficient and economic production of cell spheroids. We optimized the protocol for generating large and homogenous liver cancer cell spheroids using Huh7 hepatocellular carcinoma (HCC) cells. The large Huh7 spheroids showed apoptotic and proliferative signals in the centre and at the surface, respectively. In particular, hypoxia-induced factor-1 alpha (HIF-1α) and ERK signal activation were detected in the cell spheroids. To diminish core necrosis and increase the oncogenic character, we co-cultured spheroids with 2% human umbilical vein endothelial cells (HUVECs). HUVECs promoted proliferation and gene expression of HCC-related genes and cancer stem cell markers in the Huh7 spheroidsby activating cytokine signalling, mimicking gene expression in liver cancer. HUVECs induced angiogenesis and vessel maturation in Huh7 spheroids in vivo by activating epithelial-mesenchymal transition and angiogenic pathways. The large Huh7 cell spheroids containing HUVECs survived at higher concentrations of anti-cancer drugs (doxorubicin and sorafenib) than did monolayer cells. Our large cell spheroid provides a useful in vitro HCC model to enable intuitive observation for anti-cancer drug testing.

    Thyroid cancer is usually, relatively hypofunctional; most patients with thyroid cancer are clinically euthyroid. The combination of thyroid cancer and thyrotoxicosis is not common. We herein, report a case of follicular thyroid cancer with hyperfunctioning metastasis in a 43-year-old woman who presented with thyrotoxicosis, a cold right thyroid nodule, and low I-131 uptake at the thyroid bed. An additional total body scan with I-131 revealed a large radioiodine avid osteolytic bone metastasis with soft tissue masses and liver metastasis. The patient received treatment with total thyroidectomy, methimazole, and I-131 at a cumulative dose of 600 mCi along with recombinant human thyroid-stimulating hormone before the first I-131 treatment and palliative radiation. The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment

    The incidence and mortality rate of the primary liver cancer are very high and its postoperative metastasis and recurrence have become important factors to the prognosis of patients. Circulating tumor cells (CTC), as a new tumor marker, play important roles in the early diagnosis and individualized treatment. This paper presents an effective method to distinguish liver cancer based on the cellular scattering spectrum, which is a non-fluorescence technique based on the fiber confocal microscopic spectrometer. Combining the principal component analysis (PCA) with back propagation (BP) neural network were utilized to establish an automatic recognition model for backscatter spectrum of the liver cancer cells from blood cell. PCA was applied to reduce the dimension of the scattering spectral data which obtained by the fiber confocal microscopic spectrometer. After dimensionality reduction by PCA, a neural network pattern recognition model with 2 input layer nodes, 11 hidden layer nodes, 3 output nodes was established. We trained the network with 66 samples and also tested it. Results showed that the recognition rate of the three types of cells is more than 90%, the relative standard deviation is only 2.36%. The experimental results showed that the fiber confocal microscopic spectrometer combining with the algorithm of PCA and BP neural network can automatically identify the liver cancer cell from the blood cells. This will provide a better tool for investigating the metastasis of liver cancers in vivo, the biology metabolic characteristics of liver cancers and drug transportation. Additionally, it is obviously referential in practical application.

    Liver cancer (LC) is a serious disease that threatens human lives. LC has a high recurrence rate and poor prognosis. LC stem cells (LCSCs) play critical roles in these processes. However, the mechanism remains unclear. Reactive oxygen species (ROS) can be used to determine cell apoptosis and proliferation. However, studies of the effects of exogenous nanomaterials on LCSC ROS changes are rarely reported. In this work, quantum dots (QDs) were prepared using a hydrothermal method, and QDs were further modified with polyethylene glycol (PEG) and bovine serum albumin (BSA) using a chemical approach. The effects of QDs, PEG-modified QDs (PEG@QDs) and BSA-modified QDs (BSA@QDs) on the amounts of ROS in liver cancer PLC/PRF/5 (PLC) cells and liver cancer stem cells (LCSCs) were principally investigated. The results showed that when the concentration of QDs, PEG@QDs, and BSA@QDs were 10nM and 90nM, the ROS amount in PLC cells increased by approximately 2- to 5-fold. However, when the concentrations of these nanomaterials were 10nM and 90nM, ROS levels in LCSCs were reduced by approximately 50%. This critical path potentially leads to drug resistance and recurrence of LC. This work provides an important indication for further study of LC drug resistance and recurrence.

    Full Text Available Regular monitoring of blood α-fetoprotein (AFP and/or carcino-embryonic antigen (CEA levels is important for the routine screening of liver cancer. However, AFP and CEA have a much lower specificity than des-γ-carboxyprothrombin (DCP to detect liver cancer. Therefore, the study reported here was designed, to develop a screen-printed DCP immunosensor incorporating zinc oxide nanoparticles, for accurate determination of DCP. The designed immunosensor shows low detection limits for the detection of DCP: 0.440 ng/mL (based on impedance measurement, 0.081 ng/mL (based on real part of impedance measurement and 0.078 ng/mL (based on imaginary part of impedance measurement, within the range of 3.125 ng/mL to 2000 ng/mL. In addition, there was little interference to DCP determination by molecules such as Na+, K+, Ca2+, Cl−, glucose, urea, and uric acid. It is therefore concluded that the DCP immunosensor developed and reported here is simple, inexpensive and effective, and shows promise in the rapid screening of early-stage liver cancer at home with a point-of-care approach.

    The purpose of this study was to assess the clinical outcomes of hypofractionated radiotherapy (HFRT) with three-dimensional conformal technique for medically inoperable patients with early stage non-small-cell lung cancer (NSCLC) and to evaluate prognostic factors. We performed a retrospective review of 26 patients who underwent HFRT for early stage NSCLC between September 2005 and August 2011. Only clinical stage T1-3N0 was included. The median RT dose was 70 Gy (range, 60 to 72 Gy) and the median biologically equivalent dose (BED) was 94.5 Gy (range, 78.0 to 100.8 Gy). In 84.6% of patients, 4 Gy per fraction was used. Neoadjuvant chemotherapy with paclitaxel and cisplatin was given to 2 of 26 patients. The median follow-up time for surviving patients was 21 months (range, 13 to 49 months). The overall response rate was 53.9%, and the initial local control rate was 100%. The median survival duration was 27.8 months. Rates of 2-year overall survival, progression-free survival (PFS), local control (LC), and locoregional-free survival (LRFS) were 54.3%, 61.1%, 74.6%, and 61.9%, respectively. Multivariate analysis showed that BED (>90 vs. {<=}90 Gy) was an independent prognostic factor influencing PFS, LC, and LRFS. Severe toxicities over grade 3 were not observed. Radical HFRT can yield satisfactory disease control with acceptable rates of toxicities in medically inoperable patients with early stage NSCLC. HFRT is a viable alternative for clinics and patients ineligible for stereotactic ablative radiotherapy. BED over 90 Gy and 4 Gy per fraction might be appropriate for HFRT.

    Transarterial chemoembolization (TACE) is a form of intra-arterial catheter-based chemotherapy that selectively delivers high doses of cytotoxic drug to the tumor bed combining with the effect of ischemic necrosis induced by arterial embolization. Chemoembolization and radioembolization are at the core of the treatment of liver hepatocellular carcinoma (HCC) patients who cannot receive potentially curative therapies such as transplantation, resection or percutaneous ablation. TACE for liver cancer has been proven to be useful in local tumor control, to prevent tumor progression, prolong patients' life and control patient symptoms. Recent evidence showed in patients with single-nodule HCC of 3 cm or smaller without vascular invasion, the 5-year overall survival (OS) with TACE was similar to that with hepatic resection and radiofrequency ablation. Although being used for decades, Lipiodol(®) (Lipiodol(®) Ultra Fluid(®), Guerbet, France) remains important as a tumor-seeking and radio-opaque drug delivery vector in interventional oncology. There have been efforts to improve the delivery of chemotherapeutic agents to tumors. Drug-eluting bead (DEB) is a relatively novel drug delivery embolization system which allows for fixed dosing and the ability to release the anticancer agents in a sustained manner. Three DEBs are available, i.e., Tandem(®) (CeloNova Biosciences Inc., USA), DC-Beads(®) (BTG, UK) and HepaSphere(®) (BioSphere Medical, Inc., USA). Transarterial radioembolization (TARE) technique has been developed, and proven to be efficient and safe in advanced liver cancers and those with vascular complications. Two types of radioembolization microspheres are available i.e., SIR-Spheres(®) (Sirtex Medical Limited, Australia) and TheraSphere(®) (BTG, UK). This review describes the basic procedure of TACE, properties and efficacy of some chemoembolization systems and radioembolization agents which are commercially available and/or currently under clinical

    There are sporadic reports in the literature in which radiologic liver and lung lesions found incidentally during follow-up metastatic surveillance were shown to be caused by toxocariasis. The objective of the work discussed in this report was to identify common clinical and histopathological features of toxocariasis resembling metastatic nodules in five patients with gastrointestinal cancer. We retrospectively analyzed clinical features of five gastrointestinal cancer patients with liver or lung nodules mimicking metastasis. Serologic tests for parasitic infestations and pathologic examinations were performed. All five patients were males and three patients had gastric cancer and two had colorectal cancer. All the cases of toxocariasis were confirmed serologically. On follow-up imaging, the lesions improved or resolved, suggestive of the phenomenon of visceral larva migrans. In two patients, liver biopsy was performed and showed eosinophilic abscess. Serologic tests and liver or lung biopsy should be performed aggressively to exclude toxocariasis when patients with underlying gastrointestinal cancer present with hepatic or pulmonary nodules associated with eosinophilia, particularly if the patients have a clinical history of raw animal liver ingestion. Curative surgical intervention should not be excluded just because of multiple nodules in the liver or the lungs.

    Radiotherapy is the first treatment of choice in cases of inoperable lung cancer. This paper reported the indications and limitations of radiotherapy for squamous cell carcinoma of the lung, based on the results of long-term survivors among non-resected squamous cell carcinoma. Materials consisted of 372 cases of squamous cell carcinoma of the lung treated with radiotherapy at the National Cancer Center Hospital between May 1962 and December 1980. Histopathological diagnosis was confirmed by biopsy in all cases. Among the 372 cases, 8 survived more than 5 years. Analyzing these 8 cases according to the TNM classification of the UICC, 7 were stage I, 1 was stage II, and there were no long-term survivors with stage III or IV. Of the 8 cases only one is alive. Analyzing 7 the fatal cases, 2 succumbed due to hepatic or brain metatasis following local recurrence and one had double primary cancer of the pancreas. The remaining 4 cases did not show recurrence or metastasis and succumbed due to pneumonia or myocardial infarct. (author)

    Liver cancer has a very dismal prognosis due to lack of effective therapy. Here, we studied the therapeutic effects of hyper-interleukin15 (hyper-IL-15), which is composed of IL-15 and the sushi domain of the IL-15 receptor α chain, on metastatic and autochthonous liver cancers. Liver metastatic tumour models were established by intraportally injecting syngeneic mice with murine CT26 colon carcinoma cells or B16-OVA melanoma cells. Primary hepatocellular carcinoma (HCC) was induced by diethylnitrosamine (DEN). A hydrodynamics-based gene delivery method was used to achieve sustained hyper-IL-15 expression in the liver. Liver gene delivery of hyper-IL-15 robustly expanded CD8(+) T and NK cells, leading to a long-term (more than 40 days) accumulation of CD8(+) T cells in vivo, especially in the liver. Hyper-IL-15 treatment exerted remarkable therapeutic effects on well-established liver metastatic tumours and even on DEN-induced autochthonous HCC, and these effects were abolished by depletion of CD8(+) T cells but not NK cells. Hyper-IL-15 triggered IL-12 and interferon-γ production and reduced the expression of co-inhibitory molecules on dendritic cells in the liver. Adoptive transfer of T cell receptor (TCR) transgenic OT-1 cells showed that hyper-IL-15 preferentially expanded tumour-specific CD8(+) T cells and promoted their interferon-γ synthesis and cytotoxicity. Liver delivery of hyper-IL-15 provides an effective therapy against well-established metastatic and autochthonous liver cancers in mouse models by preferentially expanding tumour-specific CD8(+) T cells and promoting their anti-tumour effects.

    2010-01-01

    Background Morphologic imaging after radiofrequency ablation (RFA) of liver metastases is hampered by an inflammatory response in the ablation margin, making the identification of local tumor progression (LTP) difficult. The aim of this study was to evaluate the efficacy of early 18F-FDG PET/CT scanning to monitor the effectiveness of RFA in colorectal liver metastases.Methods Twelve patients with 20 metastases were treated with RFA for colorectal liver metastases. They underwent PET/CT within 2 weeks before RFA and within 24 hours after RFA (so termed "early PET/CT"). PET/CT was repeated at 1, 3, and 6 months, and then every 6 months after ablation. The standard of reference was based on available clinical and radiological follow-up data.Results Early PET/CT revealed total photopenia in 16 RFA-treated metastases, which were found to be without residual tumor on the final PET/CT scan. Three RFA-treated metastases with focal uptake were identified as local tumor progression, which necessitated further treatment. One RFA-treated metastasis with rim-shaped uptake was regarded as inflammation. The results of the early PET/CT scanning were consistent with the findings of the final follow-up. Conclusions PET/CT performed within 24 hours after RFA can effectively detect whether residual tumor exists for colorectal cancer liver metastases. The results can guide further treatment, and may improve the efficacy of RFA.

    Full Text Available The Primary Liver Carcinoma (PLC is one of the most common malignant diseases in the world. In Central Serbia during the period from 2000 to 2006 the average incidence was 16.9/100 000 that complies to the European epidemiology. The main risk factors for PLC are considered to be cirrhosis of liver and viral chronic Hepatitis B and C. The goal of this research was to analyze epidemiological data of these diseases and to state the correlation between PLC, liver cirrhosis and Hepatitis B and C in Serbia. During the research period of 6 years the correlations between PLC and the corresponding risk factors were negative. For this reason it was necessary to examine other risk factors. The high incidence of PLC in Nišavski, Toplički and Šumadijski region correlate with emerging blooms of Cyanobacteria in water reservoirs supplying these areas with drinking water. Since we examined only 7 years span and have no completed cyanotoxin analysis, it is necessary to complete more research in this field. The identification of cyanotoxins as risk factors that contribute to the development of liver cancer will help in the prevention of this disease.

    2016-01-01

    Full Text Available The goal of this study was to define Na,K-ATPase α and β subunit isoform expression and isozyme composition in colorectal cancer cells and liver metastases. The α1, α3 and β1 isoforms were the most highly expressed in tumor cells and metastases; in the plasma membrane of non-neoplastic cells and mainly in a cytoplasmic location in tumor cells. α1β1 and α3β1 isozymes found in tumor and metastatic cells exhibit the highest and lowest Na+ affinity respectively and the highest K+ affinity. Mesenchymal cell isozymes possess an intermediate Na+ affinity and a low K+ affinity. In cancer, these ions are likely to favor optimal conditions for the function of nuclear enzymes involved in mitosis, especially a high intra-nuclear K+ concentration. A major and striking finding of this study was that in liver, metastasized CRC cells express the α3β1 isozyme. Thus, the α3β1 isozyme could potentially serve as a novel exploratory biomarker of CRC metastatic cells in liver.

    Aim: To assess the feasibility, safety, and effectiveness of percutaneous cryoablation for the treatment of liver metastases from breast cancer. Materials and methods: This study included 39 liver metastases in 17 female breast cancer patients who underwent computed tomography (CT)-guided percutaneous cryoablation. The mean age of the cohort was 55 years (range 30–66 years). The tumour response was evaluated by CT performed before treatment, 1 month after treatment, and every 3 months thereafter. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) was used to assess the patients' quality of life before, 1 week, 1 month, and 3 months after cryoablation. The primary endpoints were technique effectiveness, quality of life, and complications. Results: The technical success rate was 92% with no major complication reported. At the 1-month follow-up, the primary technique effectiveness was 87.1% (34 of 39 tumours). At the 3-months follow-up, local tumour progression was observed in six of 39 lesions (15.4%). The 1-year survival from the time of cryoablation was 70.6%. The quality of life symptoms and functioning scales were preserved in patients alive at 3 months after cryoablation. The global quality of life, mean value of “pain” and “fatigue” between 3 months after cryoablation and prior to treatment showed statistically significant differences, but no clinical significance. Conclusions: Cryoablation is a safe and effective ablative therapy, providing a high rate of local tumour control in breast cancer liver metastases

    Hepatic carcinoma (HCC) is one of the most common cancer and its treatment has been considered a therapeutic challenge. Doxorubicin (Dox) is one of the most important chemotherapeutic agents used in the treatment for liver cancer. However, the efficacy of Dox therapy is restricted by the dose-dependent toxic side effects. To overcome the cardiotoxicity of Dox as well as the current problems of conventional modality treatment of HCC, we developed a locally injectable, biodegradable, and pH sensitive composite nanogels for site specific delivery. Both control and Dox loaded composite nanogel systems were analyzed by DLS, SEM, FTIR and TG/DTA. The size ranges of the control composite nanogels and their drug loaded counterparts were found to be 90±20 and 270±20 nm, respectively. The control chitin-PLA CNGs and Dox-chitin-PLA CNGs showed higher swelling and degradation in acidic pH. Drug entrapment efficiency and in vitro drug release studies were carried out and showed a higher drug release at acidic pH compared to neutral pH. Cellular internalization of the nanogel systems was confirmed by fluorescent microscopy. The cytotoxicity of the composite nanogels was analyzed toward HepG2 (human liver cancer) cell lines. Furthermore, the results of in vitro hemolytic assay and coagulation assay substantiate the blood compatibility of the system. Overall Dox-chitin-PLA CNGs system could be a promising anticancer drug delivery system for liver cancer therapy. Copyright © 2013 Elsevier B.V. All rights reserved.

    To compare the long-term survival of patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) undergoing either liver resection or transarterial chemoembolization (TACE) after propensity score matching (PSM). One hundred sixty-seven and 70 BCLC-B HCC patients undergoing liver resection and TACE were retrospectively collected. PSM function of SPSS software was conducted to reduce confounding bias between the groups. And then survival analysis was performed for the matched data. Fifty-three pairs of patients were successfully matched. And then survival analysis showed that the median survival periods and their 95% confidence intervals were 35.0 (26.3-43.7)months in the liver resection group versus 20.0(15.0-25.0) months in the TACE group. The 1, 3, 5 and 7-year survival rates were 91.0%, 49.0%, 30.0% and 17.0% in the liver resection group versus 73.0%, 25.0%, 8.0% and 5.0% respectively in the TACE group (P = 0.001). Cox regression analysis revealed that TACE, total bilirubin ≥ 34.2 µmol/L, alpha fetoprotein ≥ 400 ng/ml and tumor number ≥ 3 were independent risk factors of survival (hazard ratio >1, P < 0.05). The balance of covariates may be achieved through PSM. And for patients with BCLC-B HCC, liver resection provides better long-term overall survival than TACE.

    Hepatocellular carcinoma (HCC) and chronic liver disease (CLD) are major causes of morbidity and mortality among Hispanics. Disparities in the incidence of HCC and in CLD deaths by nativity in Hispanics have been reported. Whether individual-level risk factors could explain these disparities was assessed in a prospective study of 36,864 Hispanics (18,485 US-born and 18,379 foreign-born) in the Multiethnic Cohort. Risk factors were assessed with a baseline questionnaire and Medicare claim files. During a 19.6-year follow-up, 189 incident cases of HCC and 298 CLD deaths were identified. The HCC incidence rate was almost twice as high for US-born Hispanic men versus foreign-born Hispanic men (44.7 vs 23.1), but the rates were comparable for women (14.5 vs 13.4). The CLD mortality rate was about twice as high for US-born Hispanics versus foreign-born Hispanics (66.3 vs 35.1 for men and 42.2 vs 19.7 for women). Heavy alcohol consumption was associated with HCC and CLD in foreign-born individuals, whereas the current smoking status, hepatitis B/C viral infection, and diabetes were associated with both HCC and CLD. After adjustments for these risk factors, the hazard rate ratios for HCC and CLD death were 1.58 (95% confidence interval, 1.00-2.51) and 1.85 (95% confidence interval, 1.25-2.73), respectively, for US-born Hispanics versus foreign-born Hispanics. US-born Hispanics, particularly males, are at greater risk for HCC and death from CLD than foreign-born Hispanics. Overall known differences in risk factors do not account for these disparities. Future studies are warranted to identify factors that contribute to the elevated risk of HCC development and CLD death in US-born Hispanics.

    Chronic hepatitis B virus (HBV) infection causes liver cancer and disproportionately affects the Asian community in the U.S. In order to advance HBV and liver cancer awareness and prevention, it is important to identify existing gaps in knowledge and preventive practices among Asian Americans. Therefore, the authors administered a written questionnaire to 199 adults in the Asian-American community of the San Francisco Bay Area, California. Although the majority of adults had at least a college education, knowledge regarding HBV transmission, prevention, symptoms, risks, and occurrence was low. Fewer than 60% reported having been tested for HBV, only 31% reported having been vaccinated against HBV, and only 44% reported having had their children vaccinated. Asians, especially those born in China or Southeast Asia, had significantly poorer knowledge regarding HBV and liver cancer than non-Asians. Those with higher knowledge levels were significantly more likely to have been tested for HBV and to have had their children vaccinated. Younger adults, women, Caucasians, more highly educated individuals, those not born in China or Hong Kong, and those with a personal or family history of liver disease were more likely to have taken preventive action against HBV. Our results suggest that HBV and liver cancer knowledge among Asian Americans, especially Chinese Americans, is poor, and that better knowledge is associated with increased preventive practices. Thus, there is a need for increased HBV education and improved community-based interventions to prevent HBV-related liver disease in the high-risk Asian-American community.

    Full Text Available Background/AimsThe Korean government has expanded the coverage of the national insurance scheme for four major diseases: cancers, cardiovascular diseases, cerebrovascular diseases, and rare diseases. This policy may have a detrimental effect on the budget of the national health insurance agency. Like taxes, national insurance premiums are levied on the basis of the income or wealth of the insured.MethodsUsing a preference elicitation method, we attempted to estimate how much people are willing to pay for insurance premiums that would expand their coverage for liver cancer treatment.ResultsWe calculated the marginal willingness to pay (MWTP through the marginal rate of substitution between the two attributes of the insurance premium and the total annual treatment cost by adopting conditional logit and mixed logit models.ConclusionsThe effects of various other terms that could interact with socioeconomic status were also estimated, such as gender, income level, educational attainment, age, employment status, and marital status. The estimated MWTP values of the monthly insurance premium for liver cancer treatment range from 4,130 KRW to 9,090 KRW.

    The nuclear receptor Farnesoid X Receptor (FXR) is likely a tumor suppressor in liver tissue but its molecular mechanism of suppression is not well understood. In this study, the gene expression profile of human liver cancer cells was investigated by microarray. Bioinformatics analysis of these data revealed that FXR might regulate the mTOR/S6K signaling pathway. This was confirmed by altering the expression level of FXR in liver cancer cells. Overexpression of FXR prevented the growth of cells and induced cell cycle arrest, which was enhanced by the mTOR/S6K inhibitor rapamycin. FXR upregulation also intensified the inhibition of cell growth by rapamycin. Downregulation of FXR produced the opposite effect. Finally, we found that ectopic expression of FXR in SK-Hep-1 xenografts inhibits tumor growth and reduces expression of the phosphorylated protein S6K. Taken together, our data provide the first evidence that FXR suppresses proliferation of human liver cancer cells via the inhibition of the mTOR/S6K signaling pathway. FXR expression can be used as a biomarker of personalized mTOR inhibitor treatment assessment for liver cancer patients. -- Highlights: •FXR inhibits the proliferation of liver cancer cells by prolonging G0/G1 phase. •Microarray results indicate that mTOR-S6k signaling is involved in cellular processes in which FXR plays an important role. •FXR blocks the growth of liver cancer cells via the inhibition of the mTOR/S6K signaling pathway in vitro and in vivo.

    Liver metastasis is the main cause of death from colorectal cancer. Alcohol consumption impacts liver function and is suggested to be an independent risk factor for liver metastasis of colorectal cancer, but no experimental evidence supporting this hypothesis has been demonstrated to date. In this study, we investigated the effect of alcohol intake on liver metastasis. We examined colon cancer cell spread from the spleen in mice provided with water (control group), alcohol for 4 weeks before tumor injection (prealcohol), alcohol for 3 weeks after tumor injection (postalcohol), or alcohol throughout the 7-week study (alcohol). Alcohol intake significantly increased hepatic metastatic burden in the prealcohol (2.4-fold, P < 0.001), postalcohol (2.0-fold, P < 0.01), and alcohol groups (2.2-fold, P < 0.001). A fluorescence-based metastasis tracking assay also confirmed an alcohol-induced increase in the abundance of tumor cells in the liver (2.5-fold, P < 0.001). Investigation of the host microenvironment revealed an alcohol-induced inflammatory response marked by elevated TNFα, IL1β, IL6, and IFNγ protein levels, as well as increased expression of intercellular molecule-1 (ICAM1) in hepatic tissues after 4 weeks of alcohol consumption. Moreover, the peripheral blood of mice provided with alcohol for 4 weeks exhibited reduced natural killer and CD8(+) T-cell counts. Collectively, our findings suggest that chronic alcohol consumption accelerates liver metastasis of colorectal cancer cells through alterations to the liver microenvironment and inactivation of immune surveillance.

    Tumor heterogeneity is a major obstacle for developing effective anticancer treatments. Recent studies have pointed to large stochastic genetic heterogeneity within cancer lesions, where no pattern seems to exist that would enable a more structured targeted therapy approach. Because to date no similar information is available at the protein (phenotype) level, we employed matrix assisted laser desorption ionization (MALDI) image-guided proteomics and explored the heterogeneity of extracellular and membrane subproteome in a unique collection of eight fresh human colorectal carcinoma (CRC) liver metastases. Monitoring the spatial distribution of over 1,000 proteins, we found unexpectedly that all liver metastasis lesions displayed a reproducible, zonally delineated pattern of functional and therapeutic biomarker heterogeneity. The peritumoral region featured elevated lipid metabolism and protein synthesis, the rim of the metastasis displayed increased cellular growth, movement, and drug metabolism, whereas the center of the lesion was characterized by elevated carbohydrate metabolism and DNA-repair activity. From the aspect of therapeutic targeting, zonal expression of known and novel biomarkers was evident, reinforcing the need to select several targets in order to achieve optimal coverage of the lesion. Finally, we highlight two novel antigens, LTBP2 and TGFBI, whose expression is a consistent feature of CRC liver metastasis. We demonstrate their in vivo antibody-based targeting and highlight their potential usefulness for clinical applications. The proteome heterogeneity of human CRC liver metastases has a distinct, organized pattern. This particular hallmark can now be used as part of the strategy for developing rational therapies based on multiple sets of targetable antigens. © 2014 by the American Association for the Study of Liver Diseases.

    A meta-analysis was conducted to summarize the evidence from prospective cohort and case-control studies regarding the association between coffee intake and biliary tract cancer (BTC) and liver cancer risk. Eligible studies were identified by searches of PubMed and EMBASE databases from the earliest available online indexing year to March 2017. The dose-response relationship was assessed by a restricted cubic spline model and multivariate random-effect meta-regression. A stratified and subgroup analysis by smoking status and hepatitis was performed to identify potential confounding factors. We identified five studies on BTC risk and 13 on liver cancer risk eligible for meta-analysis. A linear dose-response meta-analysis did not show a significant association between coffee consumption and BTC risk. However, there was evidence of inverse correlation between coffee consumption and liver cancer risk. The association was consistent throughout the various potential confounding factors explored including smoking status, hepatitis, etc. Increasing coffee consumption by one cup per day was associated with a 15% reduction in liver cancer risk (RR 0.85; 95% CI 0.82 to 0.88). The findings suggest that increased coffee consumption is associated with decreased risk of liver cancer, but not BTC.

    Full text: Most of the patients of hepatocellular carcinoma (HCC) present late with inoperable disease, cirrhosis of the liver and sometimes with portal vein thrombosis. In these circumstances, chemoembolisation is not possible. Similarly, if tumor is not accessible percutaneously, percutaneous ablative procedures are also ruled out. Such patients can be offered internal radionuclide therapy. In the internal radionuclide therapy, it is desirable to deliver the maximum possible radiation to the tumor, while protecting the critical organs such as normal liver parenchyma, lungs and the bone marrow (for which critical levels of radiation doses are predetermined as 30, 12 and 1.5 Gy, respectively). This is possible with individual dosimetry, by which radiation-absorbed dose/MBq to the various organs including the tumor is calculated and the 'maximum tolerated activity (MTA)', which can be safely administered to the patient, is estimated. However, this MTA should be able to deliver enough radiation to the tumor to ablate it completely (considered to be 80-100 Gy). We conducted trans-arterial Re-188 lipiodol therapy in patients with inoperable HCC after calculating MTA with individual dosimetry, in a multi-centric trial conducted by IAEA, and tried to evaluate whether calculated MTA could deliver tumoricidal radiation dose. With a transarterially injected scout dose (185 MBq) of Re-188, radiation absorbed dose to above mentioned organs including tumor were calculated in ten patients after acquiring planar gamma camera images, using conjugate view method (images taken up to 3 hrs post-injection along with a standard source) and performing first-order corrections for scatter (by taking images both in photopeak and scatter window) and attenuation (by taking a flood source and a transmission scan of the patents prior to the administration of Re-188). Images were acquired on gamma camera(Siemens-ORBITOR or GE- Millennium VG) with high/medium-energy collimator and radiation

    Sixty-eight cases of liver cancer, 48 cases of hepatocellular carcinoma and 20 cases of metastatic liver cancer, were treated by injection of SMANCS-Lipiodol (S-L) via tumor feeding arteries. Abdominal CT was carried out on the 3 rd day, 1 week, 2 and 4 weeks after the administration. These CT images were compared with those before the administration. Both primary and metastatic liver cancers were visualized as high density area due to the selective stay of S-L. Thus, the method became useful as a diagnostic tool; several tumors were newly visualized after the administration. S-L stayed in primary tumors and metastatic tumors. There were three types of the remaining of S-L in metastatic tumors for a long period: Type A, in which S-L remained in entire tumors; Types B, in which it remained primarily in circumference of tumor and Mixed type of A and B. The anticancer effect of S-L paralleled with the extent of the remaining of S-L in tumors, which was classified from Grade 0 to Grade IV. Grade IV means that S-L was recognized in the entire areas of tumors in the every slice of CT, and in the Grade IV tumors size reduced effectively after several months period. The dosage which was necessary to attain Grade IV was 0.08 ml per square centimeters calculated by the largest slice of every tumor. From Grade 0 to III, they need additional administration of S-L until to attain Grade IV in the tumor for the effective tumor regression.

    Objective: To evaluate the local tumor control and survival data after transarterial chemoembolization with different drug combinations in the palliative treatment of patients with liver metastases of gastric cancer. Materials and methods: The study was retrospectively performed. 56 patients (mean age, 52.4) with unresectable liver metastases of gastric cancer who did not respond to systemic chemotherapy were repeatedly treated with TACE in 4-week intervals. In total, 310 chemoembolization procedures were performed (mean, 5.5 sessions per patient). The local chemotherapy protocol consisted of mitomycin alone (30.4%), mitomycin and gemcitabine (33.9%), or mitomycin, gemcitabine and cisplatin (35.7%). Embolization was performed with lipiodol and starch microspheres. Local tumor response was evaluated by MRI according to RECIST. Survival data from first chemoembolization were calculated according to the Kaplan–Meier method. Results: The local tumor control was: complete response in 1.8% (n = 1), partial response in 1.8% (n = 1), stable disease in 51.8% (n = 29) and progressive disease in 44.6% (n = 25) of patients. The 1-, 2-, and 3-year survival rate from the start of chemoembolization were 58%, 38%, and 23% respectively. The median and mean survival times were 13 and 27.1 months. A Statistically significant difference between patients treated with different chemotherapy protocols was noted (ρ = 0.045) with the best survival time in the mitomycin, gemcitabine and cisplatin group. Conclusion: Transarterial chemoembolization is a minimally invasive therapy option for palliative treatment of liver metastases in patients with gastric cancer.

    To determine if identifiable hepatic textural features are present at abdominal CT in patients with colorectal cancer (CRC) prior to the development of CT-detectable hepatic metastases. Four filtration-histogram texture features (standard deviation, skewness, entropy and kurtosis) were extracted from the liver parenchyma on portal venous phase CT images at staging and post-treatment surveillance. Surveillance scans corresponded to the last scan prior to the development of CT-detectable CRC liver metastases in 29 patients (median time interval, 6 months), and these were compared with interval-matched surveillance scans in 60 CRC patients who did not develop liver metastases. Predictive models of liver metastasis-free survival and overall survival were built using regularised Cox proportional hazards regression. Texture features did not significantly differ between cases and controls. For Cox models using all features as predictors, all coefficients were shrunk to zero, suggesting no association between any CT texture features and outcomes. Prognostic indices derived from entropy features at surveillance CT incorrectly classified patients into risk groups for future liver metastases (p < 0.001). On surveillance CT scans immediately prior to the development of CRC liver metastases, we found no evidence suggesting that changes in identifiable hepatic texture features were predictive of their development. • No correlation between liver texture features and metastasis-free survival was observed. • Liver texture features incorrectly classified patients into risk groups for liver metastases. • Standardised texture analysis workflows need to be developed to improve research reproducibility.

Resibufogenin (RBG is a major bioactive compound that was isolated from Chansu (also called toad venom or toad poison, which is a popular traditional Chinese medicine that is obtained from the skin secretions of giant toads. RBG has strong antitumor effects, but its poor aqueous solubility and its cardiotoxicity have limited its clinical use. The aim of this study was to formulate RBG-loaded poly(lactic-co-glycolic acid (PLGA-D-α-tocopheryl polyethylene glycol 1000 succinate nanoparticle (RPTN to enhance the treatment of liver cancer. RPTN, RBG-loaded PLGA nanoparticle (RPN, and RBG/coumarin-6-loaded PLGA-D-α-tocopheryl polyethylene glycol 1000 succinate nanoparticle (RCPTN were prepared. The cellular uptake of RCPTN by HepG2 and HCa-F cells was analyzed using confocal laser scanning microscopy. Apoptosis was induced in HepG2 cells by RPTN, RBG solution (RS, and 5-fluorouracil solution (used as the negative controls, as assayed using flow cytometry. LD50 (median lethal dose values were determined for RS and RPTN, and the liver-targeting properties were determined for RCPTN in intravenously injected mice. A pharmacokinetic study was conducted in rats, and the in vivo therapeutic effects of RPTN, RPN, and RS were examined in a mouse tumor model. The results showed that RCPTN simultaneously delivered both coumarin-6 and RBG into HepG2 and HCa-F cells. The ratio of apoptotic cells was increased in the RPTN group. The LD50 for RPTN was 2.02-fold higher than the value for RS. Compared to RS, RPTN and RPN both showed a significant difference in vivo not only in the pharmacodynamic study but also in

    Clinical utility of determination of serum deoxythymidine kinase (TK) activity is described. It is well known that elevated TK level is observed in leukemia and other malignant diseases, or some viral infectious diseases. The TK activity was assayed on normal subjects, hepatitis B virus (HBV) positive liver diseases and various cancer by a newly developed high sensitive method, radioenzyme assay (REA) utilizing /sup 125/I-iododeoxyuridine as the substrate. Measurement of TK activity by the REA is revealed to be useful for ''the marker of DNA metabolism anomaly'' in leukemia, etc.

    'The objective of this project is to develop critical data for changing risk-based clean-up standards for trichloroethylene (TCE). The project is organized around two interrelated tasks: Task 1 addresses the tumorigenic and dosimetry issues for the metabolites of TCE that produce liver cancer in mice, dichloroacetate (DCA) and trichloroacetate (TCA). Early work had suggested that TCA was primarily responsible for TCE-induced liver tumors, but several, more mechanistic observations suggest that DCA may play a prominent role. This task is aimed at determining the basis for the selection hypothesis and seeks to prove that this mode of action is responsible for TCE-induced tumors. This project will supply the basic dose-response data from which low-dose extrapolations would be made. Task 2 seeks specific evidence that TCA and DCA are capable of promoting the growth of spontaneously initiated cells from mouse liver, in vitro. The data provide the clearest evidence that both metabolites act by a mechanism of selection rather than mutation. These data are necessary to select between a linear (i.e. no threshold) and non-linear low-dose extrapolation model. As of May of 1998, this research has identified two plausible modes of action by which TCE produces liver tumors in mice. These modes of action do not require the compounds to be mutagenic. The bulk of the experimental evidence suggests that neither TCE nor the two hepatocarcinogenic metabolites of TCE are mutagenic. The results from the colony formation assay clearly establish that both of these metabolites cause colony growth from initiated cells that occur spontaneously in the liver of B 6 C 3 F 1 mice, although the phenotypes of the colonies differ in the same manner as tumors differ, in vivo. In the case of DCA, a second mechanism may occur at a lower dose involving the release of insulin. This observation is timely as it was recently reported that occupational exposures to trichloroethylene results in 2 to 4-fold

    The optimal surgical strategy for treating colorectal cancer with synchronous liver metastases is subject to debate. The current study sought to evaluate the outcomes of simultaneous colorectal cancer and liver metastases resection in a single center. Prospectively collected data on all patients with synchronous colorectal liver metastases who underwent simultaneous resection with curative intent were analyzed retrospectively. Patient outcomes were compared depending on the primary tumor location and type of liver resection (major or minor). Between January 2005 and August 2016, 108 patients underwent simultaneous resection of primary colorectal cancer and liver metastases. The tumor was localized to the right side of the colon in 24 patients (22%), to the left side in 40 (37%), and to the rectum in 44 (41%). Perioperative mortality occurred in 3 patients (3%). Postoperative complications were noted in 32 patients (30%), and most of these complications (75%) were grade 1 to 3 according to the Clavien-Dindo classification. Neither perioperative mortality nor the rate of postoperative complications after simultaneous resection differed among patients with cancer of the right side of the colon, those with cancer of the left side of the colon, and those with rectal cancer (4%, 2.5%, and 2%, respectively, p = 0.89) and (17%, 33%, and 34%, respectively; p = 0.29)]. The 5-year overall survival of the entire sample was 54% and the 3-year overall survival was 67 %. In conclusion, simultaneous resection for primary colorectal cancer and liver metastases is a safe procedure and can be performed without excess morbidity in carefully selected patients regardless of the location of the primary tumor and type of hepatectomy.

    Purpose: The current study was conducted to investigate the incidence and risk factors for medical complications associated with low dose rate brachytherapy in patients with medically inoperable Stage I endometrial cancer treated with irradiation alone. Methods and Materials: From 1965 through 1991 at Mallinckrodt Institute of Radiology, 150 implants were performed on 96 patients who were deemed medically unfit for hysterectomy because of advanced age, obesity, and various medical problems. The records of these patients were examined retrospectively to determine the incidence of medical complications that occurred in the first 30 days following the initiation of brachytherapy. The association of risk factors that precluded major surgery and the occurrence of brachytherapy-related complications was examined by logistic regression. Results: Of these 96 patients, 40 patients were older than 75 years, and 31 patients were deemed morbidly obese. Medical problems included hypertension in 45 patients, and diabetes in 37; there was a history of congestive heart failure in 23, stroke in 11, myocardial infarction in 10, and thromboembolism in 8. There were concurrent malignancies in five patients. Implants were performed using intrauterine Simon-Heyman capsules, tandems, and vaginal ovoids in all patients. General anesthesia was used for 98 implants, spinal anesthesia for 26, local anesthesia for 25, and epidural anesthesia for 1. The duration of anesthesia ranged from 30 to 120 min (median, 60 min). The duration of radioisotope application ranged from 11 to 96 h (median, 46 h). Preventive measures included low dose subcutaneous heparin in 55 patients (since 1978), and intermittent pneumatic compression boots in 29 (since 1985). Four patients developed life-threatening complications including myocardial infarction (two patients), congestive heart failure (one patient), and pulmonary embolism (one patient). Two of these four patients died; one with a myocardial infarction and

    Introduction: The purpose of this study was to compare the results of medium dose rate (MDR) intraluminal brachytherapy (ILBT) and high dose rate (HDR) ILBT in patients with inoperable esophageal carcinoma, with regard to dysphagia, complication rate and survival. Material and methods: Included were 114 patients with inoperable esophageal cancer who were treated with a single session of ILBT. In all cases a single dose of 15 Gy was administered, calculated at a 1 cm radius. Forty-eight patients were treated with MDR ( 137 Cs)ILBT. In June 1990 MDR was replaced by HDR and from then 66 patients were treated with HDR ( 192 Ir). Dysphagia was prospectively scored using a 5-point scale at 6 weeks, 3, 6, 9 and 12 months. Results: No significant differences were noted between the two groups with regard to pretreatment variables. In patients treated with MDR-ILBT improvement of swallowing ability was noted in 30 out of 42 evaluable patients (71%), no change in 9 (21%) and progression of dysphagia in 3 patients (8%), as compared to 34 out of 59 evaluable patients (58%), 16 (27%) and 6 (15%) resp. in de HDR-ILBT group. In the latter category, progression of dysphagia was caused by fistulae in 2 patients. The differences were not significant (ns). Additional treatment in case of recurrent or persistent dysphagia was needed in 50% of the cases in the MDR-ILBT group as compared to 41% in the HDR-ILBT group (ns). The median survival of the MDR-ILBT group was 3.9 months as compared to 4.3 months in the HDR-ILBT group (ns). In 2 patients (4%) treated with MDR-ILBT bronchio-oesphageal fistulae developed at 6 weeks and 2 months. In the HDR-ILBT group fistulae were noted in 7 cases (11%) at 2 weeks, 4 weeks, 2, 3, 3, 4 and 9 months (ns). In all of these cases persistent of recurrent tumour was present. Conclusions: No significant differences were noted with regard to palliation of dysphagia, survival and complication rate between MDR-ILBT and HDR-ILBT in the management of esophageal

    2015-01-01

    The guideline for the management of hepatocellular carcinoma (HCC) was first developed in 2003 and revised in 2009 by the Korean Liver Cancer Study Group and the National Cancer Center, Korea. Since then, many studies on HCC have been carried out in Korea and other countries. In particular, a substantial body of knowledge has been accumulated on diagnosis, staging, and treatment specific to Asian characteristics, especially Koreans, prompting the proposal of new strategies. Accordingly, the new guideline presented herein was developed on the basis of recent evidence and expert opinions. The primary targets of this guideline are patients with suspicious or newly diagnosed HCC. This guideline provides recommendations for the initial treatment of patients with newly diagnosed HCC.

    Predicting any future metastatic site of early-stage breast cancer is important as it significantly influences the prognosis of advanced disease. This study aimed at investigating the potential of claudin-2, over-expressed in breast cancer liver metastases, as a biomarker for predicting liver metastatic propensity in primary breast cancer. Claudin-2 expression was analyzed in two independent cohorts. Cohort 1 included 304 women with metastatic breast cancer diagnosed between 2002 and 2007, while cohort 2 included 237 premenopausal women with early-stage node-negative breast cancer diagnosed between 1991 and 1994. Global transcriptional profiling of fine-needle aspirates from metastases was performed, followed by immunohistochemical analyses in archival primary tumor tissue. Associations between claudin-2 expression and relapse site were assessed by univariable and multivariable Cox regression models including conventional prognostic factors. Two-sided statistical tests were used. CLDN2 was significantly up-regulated (P diagnosis and liver-specific recurrence was observed among patients with high levels of claudin-2 expression in the primary tumor (cohort 1, HR = 2.3, 95% CI = 1.3-3.9). These results suggest a novel role for claudin-2 as a prognostic biomarker with the ability to predict not only the likelihood of a breast cancer recurrence, but more interestingly, the liver metastatic potential of the primary tumor.

    We report a case of rhabdomyolysis related to S-1 plus oxaliplatin(SOX)therapy for liver metastasis of gastric cancer. A 76- year-old man who had received SOX therapy for metastatic gastric cancer was admitted to our hospital for a chief complaint of fatigue and weakness. He diagnosed with rhabdomyolysis related to SOX therapy because of his symptoms and because his laboratory studies showed significant elevation of his serum creatine kinase(CK)level. The symptoms disappeared and the CK level normalized following large-volume transfusions. Rhabdomyolysis following SOX therapy is a very rare, but severe adverse event. This is the first detailed case report of rhabdomyolysis related to SOX therapy.

    To establish an effective examination system for preoperative evaluation of liver metastasis by colon cancer, we analyzed the sensitivity, cost, and efficacy of computed tomography (CT) and ultrasonography (US) in 354 patients (including 63 patients with liver metastasis). The presence or absence of liver metastasis was ultimately diagnosed 5 years after the operation. The sensitivity, specificity, and accuracy for detecting liver metastasis were 65%, 94%, and 89%, respectively for CT, 57%, 97%, and 91% for US, and 65%, 93%, and 88% for CT plus US, and there were no significant differences among them. Neither CT nor US could fully detect intrahepatic cancer spread. The cost of detection of one patient with liver metastasis was 6,298 points for plain CT, 20,169 points for enhanced CT, and 5,773 points for US. It was concluded that CT plus US should not be employed for preoperative assessment of liver metastasis, because the detection rate of the two modalities is not significantly different, and these modalities do not compensate for each other's defects. From the standpoint of the cost-benefit relationship, US should be selected for preoperative evaluation of liver metastasis. (author)

    Twenty eight patients have received treatment for liver cancer by the intra-hepatic arterial injection of between 1 and 4 GBq of yttrium-90 labelled microspheres. The injection was performed at laparotomy. If 11.1 MBq of yttrium-90 are distributed evenly over 1 sq cm of tissue, the tissue surface will suffer an initial beta dose rate of 16.2 Gy h -1 . Special precautions are therefore essential during the injection procedure, subsequently in nursing the patient and if further intervention becomes necessary. A specially designed apparatus is used for the injection, glass spectacles are worn and if the active liver is to be handled, lead rubber gloves are used. The theatre is prepared so that contaminated items can be easily isolated and a 'spill pack' is readily available. At completion of the operation, the bremsstrahlung dose rate at 15 cm from the liver is initially 15 μSv h -1 GBq -1 . Contamination of urine is typically 20 to 50 kBq L -1 while the contamination of other body fluids is negligible. Finger doses to the surgeons has varied from 2 to 5 mSv GBq -1 injected while personnel film badges used to monitor the dose equivalent to the surgeons and ward staff have recorded maximum doses of 1.5 mSv and 300 μSv respectively. 11 refs., 1 fig., 3 tabs

    The risk of liver cancer from alpha-emitting radionuclides has been estimated for people from studies of patients injected with Thorotrast, which contains an alpha-emitting radionuclide. There is no corresponding estimation of the risk of liver cancers in people from internally-deposited beta-emitting radionuclides because of the lack of human data. Life-span studies in Beagle dogs exposed by inhalation to /sup 144/CeCl/sub 3/, a beta-emitting radionuclide, or by injection to /sup 239/Pu citrate, an alpha-emitting radionuclide, and in Chinese hamsters exposed by intravenous injections to /sup 144/Ce-/sup 144/Pr citrate or /sup 239/Pu citrate have provided information on liver cancers in these species. These radionuclides accumulated in the liver resulting in significant radiation exposure of the liver. Liver cancer occurred long after exposure. When the lifetime risks of liver cancer were calculated, /sup 239/Pu was found to be more effective than /sup 144/Ce in inducing liver cancers by factor of 10 to 12. The risk of liver cancer from internally-deposited beta emitters for people are estimated by assuming this relationship for people

    In this work, the potential use of nanoparticles as contrast agents by using spectral domain optical coherence tomography (SD-OCT) in liver tissue was demonstrated. Gold nanoparticles (average size of 25 and 70 nm), were studied in human normal and cancerous liver tissues in vitro, respectively. Each sample was monitored with SD-OCT functional imaging for 240 min. Continuous OCT monitoring showed that, after application of gold nanoparticles, the OCT signal intensities of normal liver and cancerous liver tissue both increase with time, and the larger nanoparticles tend to produce a greater signal enhancement in the same type of tissue. The results show that the values of attenuation coefficients have significant differences between normal liver tissue and cancerous liver tissue. In addition, 25 nm gold nanoparticles allow higher penetration depth than 70 nm gold nanoparticles in liver tissues. (paper)

    This study aims to understand the medical expenditure for liver cancer during 2002-2011 in urban areas of China. This is a retrospective study. Based on a stratified cluster sampling method, a medical expenditure survey collected basic personal information from related medical records. Two-tailed independent sample t-test, variance analysis, and Student-Newman-Keuls Tests were used in cost analysis for the corresponding data types. A total of 12,342 liver cancer patients were included in the analysis. Overall average medical expenditure per case for liver cancer diagnosis and treatment in China has increased from ¥21, 950 to ¥40, 386 over the study period. For each liver cancer patient diagnosed between 2009 and 2011, the average expenditures were 29,332 CNY for stage I, 35,754 CNY for stage II, 34,288 CNY for stage III, and 30,275 CNY for stage IV diseases (P medical expenditure and it rose from 48.01% to 52.96% during these ten years, and the share of nursing fee expenses was the lowest (around 1%). Over the entire 10-year data period, the per capita expenditure of the east region (32,983 CNY) was higher than that of the west region (26,219 CNY) and slightly higher than the central region (31,018 CNY, P medical expenditure is heavy for families. Early diagnosis and treatment for liver cancer will save medical expenditure. The economic burden of liver cancer is high in China and related medical expenditure has increased.

    We aimed at evaluating the risk of liver cancer in different levels of HBsAg among Chinese men and women. We carried out a nested case-control study including 363 cases and 3,511 controls in two population-based cohorts in Shanghai. Plasma samples collected at enrollment were quantified for HBsAg levels using the Architect QT assay. Conditional logistic regression was performed to estimate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for liver cancer, with adjustment for potential confounders. HBsAg was detected in 6.29% of control subjects overall (7.02% in men and 4.98% in women). HBsAg levels were positively associated with liver cancer risk in a dose-response manner (ptrend  women. In men, the adjusted ORs increased from 7.27 (95% CI: 3.49-15.15) at the lowest detectable level of HBsAg (5-9 IU/ml) to 7.16 (95% CI: 3.21-15.96), 34.30 (95% CI: 16.94-69.44), and 47.33 (95% CI: 23.50-95.34) at the highest level of HBsAg (≥1,000 IU/ml) compared to those negative for HBsAg. The corresponding ORs were much lower for women, from 1.37 (95% CI: 0.25-7.47), 3.81 (95% CI: 1.09-13.28), 7.36 (95% CI: 2.41-22.46) and 16.86 (95% CI: 7.24-39.27), respectively. HBsAg quantification has potential to distinguish individuals at different risks of liver cancer. Men with the lowest detectable level of HBsAg should still pay attention to their liver cancer risks, but those with a higher level may be given a higher priority in future liver cancer surveillance program. © 2016 UICC.

    Methionine adenosyltransferase (MAT) is an essential enzyme that is responsible for the biosynthesis of S-adenosylmethionine (SAMe), the principal methyl donor and precursor of polyamines. MAT1A is expressed in normal liver and MAT2A is expressed in all extrahepatic tissues. MAT2A expression is increased in human colon cancer and in colon cancer cells treated with mitogens, whereas silencing MAT2A resulted in apoptosis. The aim of the current work was to examine the mechanism responsible for MAT2A-dependent growth and apoptosis. We found that in RKO (human adenocarcinoma cell line) cells, MAT2A siRNA treatment lowered cellular SAMe and putrescine levels by 70–75%, increased apoptosis and inhibited growth. Putrescine supplementation blunted significantly MAT2A siRNA-induced apoptosis and growth suppression. Putrescine treatment (100 pmol/L) raised MAT2A mRNA level to 4.3-fold of control, increased the expression of c-Jun and c-Fos and binding to an AP-1 site in the human MAT2A promoter and the promoter activity. In human colon cancer specimens, the expression levels of MAT2A, ornithine decarboxylase (ODC), c-Jun and c-Fos are all elevated as compared to adjacent non-tumorous tissues. Overexpression of ODC in RKO cells also raised MAT2A mRNA level and MAT2A promoter activity. ODC and MAT2A are also overexpressed in liver cancer and consistently, similar MAT2A-ODC-putrescine interactions and effects on growth and apoptosis were observed in HepG2 cells. In conclusion, there is a crosstalk between polyamines and MAT2A. Increased MAT2A expression provides more SAMe for polyamines biosynthesis; increased polyamine (putrescine in this case) can activate MAT2A at the transcriptional level. This along with increased ODC expression in cancer all feed forward to further enhance the proliferative capacity of the cancer cell. -- Highlights: • MAT2A knockdown depletes putrescine and leads to apoptosis. • Putrescine attenuates MAT2A knockdown-induced apoptosis and growth

    Liver cancer, particularly hepatocellular carcinoma, is one of the most common malignant diseases in many developed and developing countries. It is also one of the most common diseases endangering the people's lives and health heavily. Surgery is very effective in early-stage patients. Unfortunately, there is less than 10% of the patients with hepatocellular carcinoma fitting for surgical therapy. Instead of surgical therapy, other methods are considered for patients in whom surgery may not work well. Systemic administration of chemotherapeutic agents is not often considered in liver cancer patients, due to discouraging result and adverse side effects. Also, hepatocellular carcinoma is not keen on usual radioactive therapy. However, method of inner interventional radioactive nuclide is a potential way to cure liver tumors. Hepatocellular carcinoma would be cured with inner interventional radioactive nuclide, which is a hot topic in experimental research on hepatocellular carcinoma at home and abroad. The purpose of the study is to label Yttrium-90 with lipiodol by means of the chemical extraction method and research the stability of labeled Yttrium-90 ( 90 Y-P204-Lipiodol) in serum of a newly-born cattle and human's blood. We chose to label steady yttrium with lipiodol, because radioactive yttrium has great nuclear character for liver cancer, yttrium-90 can eradiate pure β radial, and it's half time is 64 hours. Average energy of it is 0.93 Mev, the highest energy is 2.27 Mev. Yttrium-90 can be labeled with lipiodol by means of the chemical extraction method, which is mature in chemical techniques, combined with method of radioactive nuclide labeled in. nuclear medicine. At first, yttrium-90 is extracted in certain condition(pH, temperature, whisk time, whisk frequency, etc ) after adding yttrium-90 solution. We use some distilled water to balance the labeled organic phase twice, and test the stability of labeled yttrium-90 in serum of a newly-born cattle and

    Colorectal cancer is a common cancer and a leading cause of cancer-related death worldwide. The liver is a dominant metastatic site for patients with colorectal cancer. Molecular mechanisms that allow colorectal cancer cells to form liver metastases are largely unknown. Activation of epithelial-mesenchymal transition is the key step for metastasis of cancer cells. We recently reported that dual-specificity tyrosine-regulated kinase 2 (DYRK2) controls epithelial-mesenchymal transition in breast cancer and ovarian serous adenocarcinoma. The aim of this study is to clarify whether DYRK2 regulates liver metastases of colorectal cancer. We show that the ability of cell invasion and migration was abrogated in DYRK2-overexpressing cells. In an in vivo xenograft model, liver metastatic lesions were markedly diminished by ectopic expression of DYRK2. Furthermore, we found that patients whose liver metastases expressed low DYRK2 levels had significantly worse overall and disease-free survival. Given the findings that DYRK2 regulates cancer cell metastasis, we concluded that the expression status of DYRK2 could be a predictive marker for liver metastases of colorectal cancer. © 2017 The Authors.

    Objective: To investigate the synergistic antitumor effects of adenovirus-mediated IL-12 gene therapy in combination with radiotherapy in mice bearing liver cancer. Methods: Balb/c mice bearing liver cancer received the treatment at day 1 with tumor local irradiation (TLI) of 20 Gy or mask irradiation when tumor size reached 0.6-1.0 cm. Within 1 hour after irradiation, adenovirus containing IL-12 gene or PBS was intra-tumor injected once a week. Forty-eight hours after the second injection, IFN-γ levels in sera and the supernatant of cultured spleen cells were assayed by ELISA, CTL activity of spleen cells was measured by 3 H-TdR release assay, and phenotypes of tumor-infiltrating lymphocytes were analysed by immunohistochemical staining. Results: The growth of tumors in animals treated with a combination of IL-12 gene therapy and TLI was inhibited more significantly than those with either single treatment (P + and CD8 + lymphocyte infiltration and tumor-specific cytolytic activities, and the levels of IFN-γ in sera were higher in IL-12 gene therapy and IL-12 gene therapy combined with TLI groups. Conclusion: These results suggest that IL-12 gene therapy combined with radiotherapy is more effective than both single treatment modalities and can induce specific antitumor immuno-response greatly

    This study evaluates the microscopic characteristics of liver metastases from colorectal cancer (LMCRC) invasion and provides a reference for expansion from gross tumor volume (GTV) to clinical targeting volume (CTV). Data from 129 LMCRC patients treated by surgical resection at our hospital between January 2008 and September 2009 were collected for study. Tissue sections used for pathology and clinical data were reviewed. Patient information used for the study included gender, age, original tumor site, number of tumors, tumor size, levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199), synchronous or metachronous liver metastases, and whether patients received chemotherapy. The distance of liver microinvasion from the tumor boundary was measured microscopically by two senior pathologists. Of 129 patients evaluated, 81 (62.8 %) presented microinvasion distances from the tumor boundary ranging between 1.0 − 7.0 mm. A GTV-to-CTV expansion of 5, 6.7, or 7.0 mm was required to provide a 95, 99, or 100 % probability, respectively, of obtaining clear resection margins by microscopic observation. The extent of invasion was not related to gender, age, synchronous or metachronous liver metastases, tumor size, CA199 level, or chemotherapy. The extent of invasion was related to original tumor site, CEA level, and number of tumors. A scoring system was established based on the latter three positive predictors. Using this system, an invasion distance less than 3 mm was measured in 93.4 % of patients with a score of ≤1 point, but in only 85.7 % of patients with a score of ≤2 points. The extent of tumor invasion in our LMCRC patient cohort correlated with original tumor site, CEA level, and number of tumors. These positive predictors may potentially be used as a scoring system for determining GTV-to-CTV expansion

    As the study of radioactive nuclide, Holmium-166 in the treatment of liver cancer(hepatocellular carcinoma), this study was performed under the base of animal experimental. Using dog liver, percutaneous injection of Ho-166 MAA or chitosan with premade dose was done under the ultrasound guidance. Continuously the same procedure as previous one was performed in the skin hapatoma, which was developed by the injection of hepatocellular carcinoma cell in the nude mouse, In case of injected normal liver of dog, imaging study including ultrasound, CT and MRI was done in order to evaluate effect of Ho-166 and pathologic reaction. The result showed well defined nectosis of normal liver as well as skin hepatoma. The area of nectosis is dependent on the dose of injected Ho-166. Generally, pathologic reaction is tissue coagulation nectosis, Ho-166 particles, fibrosis and hemorrhage. In the clinical study, 50 patients with hapatoma was selected for this study under the agreement of patient. Under ultrasound guidance percutaneous injection of Ho-166 Maa or chitosan to tumor was performed and follow-up study was extended from 6 to 12 month. The result showed that 64% of patient were completely treated. Overall, the effect of treatment could be obtained in 41 patient (82%) among 50 hepatoma patient. Conclusively Ho-166 is thought to be a compromising agent in the treatment of hepatocellular carcinoma and one of therapeutic modality, if it is established internally and world-wide. In the future, the popular percutaneous ethanol injection method will be replaced to this method. 19 refs., 1 tabs., 14 figs. (author)

    Primary liver cancer (PLC) is one of the common malignant tumors. Liver acquisition with acceleration volume acquisition (LAVA), which allows simultaneous dynamic enhancement of the hepatic parenchyma and vasculature imaging, is of great help in the diagnosis of PLC. This study aimed to evaluate application of the fluoroscopic triggering 3D LAVA technique in the imaging of PLC and liver vasculature. The clinical data and imaging findings of 38 adults with PLC (22 men and 16 women; average age 52 years), pathologically confirmed by surgical resection or biopsy, were collected and analyzed. All magnetic resonance images were obtained with a 1.5-T system (General Electrics Medical Systems) with an eight-element body array coil and application of the fluoroscopic triggering 3D LAVA technique. Overall image quality was assessed on a 5-point scale by two experienced radiologists. All the nodules and blood vessel were recorded and compared. The diagnostic accuracy and feasibility of LAVA were evaluated. Thirty-eight patients gave high quality images of 72 nodules in the liver for diagnosis. The accuracy of LAVA was 97.2% (70/72), and the coincidence rate between the extent of tumor judged by dynamic enhancement and pathological examination was 87.5% (63/72). Displayed by the maximum intensity projection reconstruction, nearly all cases gave satisfactory images of branches III and IV of the hepatic artery. Furthermore, small early-stage enhancing hepatic lesions and the parallel portal vein were also well displayed. Sequence of LAVA provides good multi-phase dynamic enhancement scanning of hepatic lesions. Combined with conventional scanning technology, LAVA effectively and safely displays focal hepatic lesions and the relationship between tumor and normal tissues, especially blood vessels.

  2. The 2-oxoglutarate carrier promotes liver cancer by sustaining mitochondrial GSH despite cholesterol loading

    Full Text Available Cancer cells exhibit mitochondrial cholesterol (mt-cholesterol accumulation, which contributes to cell death resistance by antagonizing mitochondrial outer membrane (MOM permeabilization. Hepatocellular mt-cholesterol loading, however, promotes steatohepatitis, an advanced stage of chronic liver disease that precedes hepatocellular carcinoma (HCC, by depleting mitochondrial GSH (mGSH due to a cholesterol-mediated impairment in mGSH transport. Whether and how HCC cells overcome the restriction of mGSH transport imposed by mt-cholesterol loading to support mGSH uptake remains unknown. Although the transport of mGSH is not fully understood, SLC25A10 (dicarboxylate carrier, DIC and SLC25A11 (2-oxoglutarate carrier, OGC have been involved in mGSH transport, and therefore we examined their expression and role in HCC. Unexpectedly, HCC cells and liver explants from patients with HCC exhibit divergent expression of these mitochondrial carriers, with selective OGC upregulation, which contributes to mGSH maintenance. OGC but not DIC downregulation by siRNA depleted mGSH levels and sensitized HCC cells to hypoxia-induced ROS generation and cell death as well as impaired cell growth in three-dimensional multicellular HCC spheroids, effects that were reversible upon mGSH replenishment by GSH ethyl ester, a membrane permeable GSH precursor. We also show that OGC regulates mitochondrial respiration and glycolysis. Moreover, OGC silencing promoted hypoxia-induced cardiolipin peroxidation, which reversed the inhibition of cholesterol on the permeabilization of MOM-like liposomes induced by Bax or Bak. Genetic OGC knockdown reduced the ability of tumor-initiating stem-like cells to induce liver cancer. These findings underscore the selective overexpression of OGC as an adaptive mechanism of HCC to provide adequate mGSH levels in the face of mt-cholesterol loading and suggest that OGC may be a novel therapeutic target for HCC treatment.

    Primary liver cancer is a global disease that is on the increase. Hepatocellular carcinoma (HCC) accounts for most primary liver cancers and has a notably low survival rate, largely attributable to late diagnosis, resistance to treatment, tumour recurrence and metastasis. MicroRNAs (miRNAs/miRs) are regulatory RNAs that modulate protein synthesis. miRNAs are involved in several biological and pathological processes including the development and progression of HCC. Given the poor outcomes with current HCC treatments, miRNAs represent an important new target for therapeutic intervention. Several studies have demonstrated their role in HCC development and progression. While many risk factors underlie the development of HCC, one process commonly altered is iron homeostasis. Iron overload occurs in several liver diseases associated with the development of HCC including Hepatitis C infection and the importance of miRNAs in iron homeostasis and hepatic iron overload is well characterised. Aberrant miRNA expression in hepatic fibrosis and injury response have been reported, as have dysregulated miRNA expression patterns affecting cell cycle progression, evasion of apoptosis, invasion and metastasis. In 2009, miR-26a delivery was shown to prevent HCC progression, highlighting its therapeutic potential. Several studies have since investigated the clinical potential of other miRNAs with one drug, Miravirsen, currently in phase II clinical trials. miRNAs also have potential as biomarkers for the diagnosis of HCC and to evaluate treatment efficacy. Ongoing studies and clinical trials suggest miRNA-based treatments and diagnostic methods will have novel clinical applications for HCC in the coming years, yielding improved HCC survival rates and patient outcomes.

    Staging of colorectal cancer often fails to discriminate outcomes of patients with morphologically similar tumours that exhibit different clinical behaviours. Data from several studies suggest that the gastrin family of growth factors potentiates colorectal cancer tumourigenesis. The aim of this study was to investigate whether progastrin expression may predict clinical outcome in colorectal cancer. Patients with colorectal adenocarcinoma of identical depth of invasion who had not received neoadjuvant therapy were included. The patients either had stage IIa disease with greater than 3-year disease-free survival without adjuvant therapy or stage IV disease with liver metastases on staging CT. Progastrin expression in tumour sections was scored with reference to the intensity and area of immunohistochemical staining. Progastrin expression by stage IV tumours was significantly greater than stage IIa tumours with mean progastrin immunopositivity scores of 2.1 ± 0.2 versus 0.5 ± 0.2, respectively (P colorectal cancer and supports its clinical relevance and potential use as a biomarker.

  6. A new device for liver cancer biomarker detection with high accuracy

    2015-06-01

    Full Text Available A novel cantilever array-based bio-sensor was batch-fabricated with IC compatible MEMS technology for precise liver cancer bio-marker detection. A micro-cavity was designed in the free end of the cantilever for local antibody-immobilization, thus adsorption of the cancer biomarker is localized in the micro-cavity, and the adsorption-induced k variation can be dramatically reduced with comparison to that caused by adsorption of the whole lever. The cantilever is pizeoelectrically driven into vibration which is pizeoresistively sensed by Wheatstone bridge. These structural features offer several advantages: high sensitivity, high throughput, high mass detection accuracy, and small volume. In addition, an analytical model has been established to eliminate the effect of adsorption-induced lever stiffness change and has been applied to precise mass detection of cancer biomarker AFP, the detected AFP antigen mass (7.6 pg/ml is quite close to the calculated one (5.5 pg/ml, two orders of magnitude better than the value by the fully antibody-immobilized cantilever sensor. These approaches will promote real application of the cantilever sensors in early diagnosis of cancer.

    Liver X receptors (LXRs) are nuclear receptors family of ligand-dependent transcription factors that play a crucial role in regulating cholesterol metabolism and inflammation. Recent studies show that LXR agonists exhibit anti-cancer activities in a variety of cancer cell lines including prostate. To further identify the potential mechanisms of LXRα activation on prostate cancer, we investigated the effect of LXR agonist T0901317 on PC3 prostate cancer cell and in which activity of beta-catenin pathway involved. Prostate cancer PC3 cells were transfected with LXR-a siRNA and treated with LXR activator T0901317. qRT-PCR and western blot were used to detect the LXR-a expression. beta-catenin, cyclin D1 and c-MYC were analyzed by western blot. Cell apoptosis was examined by flow cytometry and Cell proliferation was assessed by Cell Counting Kit-8 assay. Cell migration was detected by Transwell chambers. Data showed that T0901317 significantly inhibited PC3 cell proliferation as well as invasion and increased apoptosis in vitro. Furthermore, we found that LXRα activation induced the reduction of beta-catenin expression in PC3 cells, and this inhibitory effect could be totally abolished when cells were treated with LXRα. Meanwhile, the expression of beta-catenin target gene cyclin D1 and c-MYC were also decreased. This study provided additional evidence that LXR activation inhibited PC-3 prostate cancer cells via suppressing beta-catenin pathway. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Full Text Available We previously reported increased levels of protein-linked fucosylation with the development of liver cancer and identified many of the proteins containing the altered glycan structures. One such protein is alpha-1-antitrypsin (A1AT. To advance these studies, we performed N-linked glycan analysis on the five major isoforms of A1AT and completed a comprehensive study of the glycosylation of A1AT found in healthy controls, patients with hepatitis C- (HCV induced liver cirrhosis, and in patients infected with HCV with a diagnosis of hepatocellular carcinoma (HCC.Patients with liver cirrhosis and liver cancer had increased levels of triantennary glycan-containing outer arm (alpha-1,3 fucosylation. Increases in core (alpha-1,6 fucosylation were observed only on A1AT from patients with cancer. We performed a lectin fluorophore-linked immunosorbent assay using Aleuria Aurantia lectin (AAL, specific for core and outer arm fucosylation in over 400 patients with liver disease. AAL-reactive A1AT was able to detect HCC with a sensitivity of 70% and a specificity of 86%, which was greater than that observed with the current marker of HCC, alpha-fetoprotein. Glycosylation analysis of the false positives was performed; results indicated that these patients had increases in outer arm fucosylation but not in core fucosylation, suggesting that core fucosylation is cancer specific.This report details the stepwise change in the glycosylation of A1AT with the progression from liver cirrhosis to cancer and identifies core fucosylation on A1AT as an HCC specific modification.

    Histological features of primary liver cancer among atomic-bomb survivors and their relationship to hepatitis B (HBV) and C viral (HCV) infections are of special interest because of the increased risk of liver cancer in persons exposed to ionizing radiation and the high and increasing liver cancer rates in Japan and elsewhere. We conducted a pathology review of liver cancers occurring from 1958 to 1987 among subjects in the 120,321 member cohort of 1945 Hiroshima and Nagasaki residents. A panel of pathologists classified tumor histological types and defined accompanying cirrhotic changes of the liver. Archival tissue samples were assessed for HBV using pathology stains and PCR. Reverse transcriptase (RT) PCR was used to determine HCV status. We used unconditional logistic regression to compare 302 hepatocellular carcinoma (HCC) cases to 53 cholangiocarcinoma (CC) cases, adjusting for age, year of diagnosis, sex and viral status. Cirrhotic changes occurred significantly more often among HCC than CC cases (76% in HCC and 6% in CC). Compared to CC cases, HCC cases were 10.9 times more likely to be HBV-positive (95% confidence interval: 2.1-83.2) and 4.3 times more likely to be HCV-positive (95% confidence interval: 1.1-20.5) No significant differences were found between HCC and CC cases in radiation exposures. The predominance of HCC in the atomic-bomb survivors follows the background liver cancer pattern in Japan. Our findings suggest that HBV and HCV are involved in the pathogenesis of HCC with or without cirrhosis and are significantly less important in that of CC. (author)

    Obesity increases the risk of cancers, including hepatocellular carcinomas (HCC). However, the precise molecular mechanisms through which obesity promotes HCC development are still unclear. Recent studies have shown that gut microbiota may influence liver diseases by transferring its metabolites and components. Here, we show that the hepatic translocation of obesity-induced lipoteichoic acid (LTA), a Gram-positive gut microbial component, promotes HCC development by creating a tumor-promoting microenvironment. LTA enhances the senescence-associated secretory phenotype (SASP) of hepatic stellate cells (HSC) collaboratively with an obesity-induced gut microbial metabolite, deoxycholic acid, to upregulate the expression of SASP factors and COX2 through Toll-like receptor 2. Interestingly, COX2-mediated prostaglandin E 2 (PGE 2 ) production suppresses the antitumor immunity through a PTGER4 receptor, thereby contributing to HCC progression. Moreover, COX2 overexpression and excess PGE 2 production were detected in HSCs in human HCCs with noncirrhotic, nonalcoholic steatohepatitis (NASH), indicating that a similar mechanism could function in humans. Significance: We showed the importance of the gut-liver axis in obesity-associated HCC. The gut microbiota-driven COX2 pathway produced the lipid mediator PGE 2 in senescent HSCs in the tumor microenvironment, which plays a pivotal role in suppressing antitumor immunity, suggesting that PGE 2 and its receptor may be novel therapeutic targets for noncirrhotic NASH-associated HCC.

    Purpose: To propose a new method to estimate lung mean dose (LMD) using technetium-99m labeled macroaggregated albumin ({sup 99m}Tc-MAA) single photon emission CT (SPECT)/CT for {sup 90}Yttrium radioembolization of liver tumors and to compare the LMD estimated using SPECT/CT with clinical estimates of LMD using planar gamma scintigraphy (PS). Methods and Materials: Images of 71 patients who had SPECT/CT and PS images of {sup 99m}Tc-MAA acquired before TheraSphere radioembolization of liver cancer were analyzed retrospectively. LMD was calculated from the PS-based lung shunt assuming a lung mass of 1 kg and 50 Gy per GBq of injected activity shunted to the lung. For the SPECT/CT-based estimate, the LMD was calculated with the activity concentration and lung volume derived from SPECT/CT. The effect of attenuation correction and the patient's breathing on the calculated LMD was studied with the SPECT/CT. With these effects correctly taken into account in a more rigorous fashion, we compared the LMD calculated with SPECT/CT with the LMD calculated with PS. Results: The mean dose to the central region of the lung leads to a more accurate estimate of LMD. Inclusion of the lung region around the diaphragm in the calculation leads to an overestimate of LMD due to the misregistration of the liver activity to the lung from the patient's breathing. LMD calculated based on PS is a poor predictor of the actual LMD. For the subpopulation with large lung shunt, the mean overestimation from the PS method for the lung shunt was 170%. Conclusions: A new method of calculating the LMD for TheraSphere and SIR-Spheres radioembolization of liver cancer based on {sup 99m}Tc-MAA SPECT/CT is presented. The new method provides a more accurate estimate of radiation risk to the lungs. For patients with a large lung shunt calculated from PS, a recalculation of LMD based on SPECT/CT is recommended.

    2011-01-01

    Objective: To determine the value of clinical and CT assessment of hepatic reserve function in patients with cirrhosis and liver cancer undergoing transcatheter arterial chemoembolization (TACE). Methods: Sixty consecutive patients with cirrhosis and primary liver cancer treated using TACE were studied prospectively. The hepatic reserve function was evaluated using Child-Pugh classification and modified Child-Pugh classification before and after TACE respectively. The modified Child-Pugh classification was an integration of Child-Pugh classification, morphological evaluation of the cirrhotic liver and measurement of tumor-free liver volume by CT. Agreement rates of the two methods for assessing the hepatic reserve function peri-operatively and the survival time were calculated. Results: The agreement rates of Child-Pugh classification and modified Child-Pugh classification for assessing the postoperative hepatic reserve function were 55.6% and 83.3% respectively in well-compensated cases (P 2 =11.2, 8.7, 13.5, P<0.001) shorter than that of patients in modified Child-Pugh classes A (71 months), B (46 months) and C (7.6 months). Conclusion: Modified Child-Pugh classification is better than Child-Pugh classification for assessing the hepatic reserve function in patients with cirrhosis and liver cancer undergoing TACE.

    A 64-year-old man who underwent right hemicolectomy 3.5 years ago for ascending colon cancer and then RF ablation for two metastatic nodules in the liver was admitted to our hospital with a new metastatic nodule in the S6/7 segment of the liver. The CT scan showed a low attenuating metastatic nodule 2.2 cm in diameter in the S6/7 segment of the liver, and the liver showed peripheral bile duct dilatation. This nodule was treated with percutaneous RF ablation. A follow-up CT seven months after RF ablation showed the presence of a viable tumor in the RF ablation zone, with tumor extension along the dilated bile duct. These findings were confirmed on the resected specimen.

    Regorafenib is effective for metastatic colorectal cancer but its toxicity such as hemorrhage should be considered. The safety of regorafenib for the patient with the liver disease is not known. Seventy-one-year old man of colon cancer had myodesopsia and blood stool after 14 days from the initiation of regorafenib administration with 50% dose reduction due to liver dysfunction. Fundus examination revealed hemorrhage of the retinal vein. Regorafenib treatment was discontinued and observational therapy was pursued. Retinal and gastrointestinal hemorrhage resolved in 1 week. Retinal hemorrhage should be considered as the differential diagnosis of myodesopsia in the patient treated by regorafenib. Safety and pharmacokinetic of continuous regorafenib administration for patients with liver dysfunction remains to be clarified.

    BACKGROUND: Neoplasm seeding is a serious complication after liver metastases biopsy. Reported incidences vary between 10% and 19% for colorectal cancer (CRC) and are unknown for breast cancer (BC). The aim of this retrospective study was to determine the frequency of tumor seeding after ultrasound...... retrospectively reviewed. The endpoint was the development of abdominal wall recurrence following liver biopsy. RESULTS: Of total 2981 biopsies we identified 278 patients with CRC and 155 patients with BC biopsy-verified liver metastases. During the median follow-up of 25 months after biopsy (range 3-253 months......), no seeding was recorded in patients with BC. Within the median follow-up of 34 months (3-111 months), seeding was registered in 17/278 (6%) of patients with CRC; three patients of 278 (1%) had undoubtedly biopsy-related seeding, which became apparent six, nine, and 26 months after biopsy, respectively...

    Full Text Available Colorectal cancer affects over one million people worldwide annually, with the liver being the most common site of metastatic spread. Adequate resection of hepatic metastases is the only chance for a cure in a subset of patients, and five-year survival increases to 35% with complete resection. Traditionally, computed tomographic imaging (CT was utilized for staging and to evaluate metastases in the liver. Recently, the introduction of hepatobiliary contrast-enhanced magnetic resonance imaging (MRI agents including gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Eovist in the United States, Primovist in Europe, or Gd-EOB-DTPA has proved to be a sensitive method for detection of hepatic metastases. Accurate detection of liver metastases is critical for staging of colorectal cancer as well as preoperative planning.

    Purpose: To assess the use of brachytherapy (BT) with or without external beam radiation (EBRT) in inoperable stage I endometrial adenocarcinoma in the United States and to determine the effect of BT on overall survival (OS) and cause-specific survival (CSS). Methods and Materials: Data between 1998 and 2011 from the National Cancer Institute's Surveillance, Epidemiology and End Results database were analyzed. Coarsened exact matching was used to adjust for differences in age and grade between patients who received BT and those who did not. Prognostic factors affecting OS and CSS were evaluated using the Kaplan-Meier product-limit method and a Cox proportional hazards regression model. Results: A total of 460 patients with inoperable stage I endometrial adenocarcinoma treated with radiation therapy were identified. Radiation consisted of either EBRT (n=260) or BT with or without EBRT (n=200). The only factor associated with BT use was younger patient age (median age, 72 vs 76 years, P=.001). Patients who received BT had a higher 3-year OS (60% vs 47%, P<.001) and CSS (82% vs 74%, P=.032) compared with those who did not. On multivariate analysis, BT use was independently associated with an improved OS (hazard ratio [HR] 0.67, 95% confidence interval [CI] 0.52-0.87) and CSS (HR 0.61, 95% CI 0.39-0.93). When patients were matched on age, BT use remained significant on multivariate analysis for OS (HR 0.65, 95% CI 0.48-0.87) and CSS (HR 0.52, 95% CI 0.31-0.84). When matched on age and grade, BT remained independently associated with improved OS and CSS (OS HR 0.62, 95% CI 0.46-0.83; CSS HR 0.57, 95% CI 0.34-0.92). Conclusion: Brachytherapy is independently associated with improved OS and CSS. It should be considered as part of the treatment regimen for stage I inoperable endometrial cancer patients undergoing radiation.

    Full Text Available Abstract Background Treatment records and follow-up data on 40 patients with primary and metastatic liver malignancies who underwent a single whole-liver treatment with Y-90 resin microspheres (SIR-Spheres® Sirtex Medical, Lake Forest, IL were retrospectively reviewed. The objective of the study was to evaluate the anatomic and physiologic determinants of radiation dose distribution, and the dose response of tumor and liver toxicity in patients with liver malignancies who underwent hepatic arterial Y-90 resin microsphere treatment. Methods Liver and tumor volume calculations were performed on pre-treatment CT scans. Fractional tumor and liver flow characteristics and lung shunt fractions were determined using hepatic arterial Tc-99m MAA imaging. Absorbed dose calculations were performed using the MIRD equations. Liver toxicity was assessed clinically and by liver function tests. Tumor response to therapy was assessed by CT and/or tumor markers. Results Of the 40 patients, 5 had hepatocellular cancer (HCC, and 35 had metastatic liver tumors (15 colorectal cancer, 10 neuroendocrine tumors, 4 breast cancer, 2 lung cancer, 1 ovarian cancer, 1 endometrial cancer, and 2 unknown primary adenocarcinoma. All patients were treated in a salvage setting with a 3 to 80 week follow-up (mean: 19 weeks. Tumor volumes ranged from 15.0 to 984.2 cc (mean: 294.9 cc and tumor to normal liver uptake ratios ranged from 2.8 to 15.4 (mean: 5.4. Average administered activity was 1.2 GBq (0.4 to 2.4 GBq.

    The aim of this study was to compare liver transplant recipients (LTRs) with the general population regarding their knowledge of skin cancer, sun health, sun protection behaviors, and affecting factors. This cross-sectional study was conducted in Turkey between March 2016 and September 2016 with 104 LTRs and 100 participants from the general population group (GPG). The mean age of the LTRs was 53.2 ± 11.8 and that of the GPG was 42.7 ± 14.5. The LTRs' skin cancer and sun knowledge were significantly lower than in the GPG, but there was no difference between the two groups in terms of their sun protection behavior scores. The most commonly used sun protection behaviors of LTRs were not being outside and not sunbathing between 10 a.m. and 4 p.m., wearing clothing that covers the skin, and avoiding the solarium. Behaviors commonly practiced by the GPG were wearing sunglasses, wearing sunscreen with a sun protection factor of 15 or higher before going outside, wearing sunscreen at the beach, while swimming or doing physical activity outside, and reapplying it every 2 h. Results of our study will contribute to the development of education and training programs for LTRs on skin cancer. The results also demonstrated the importance of practicing adequate sun protection behaviors which will certainly impact their future health.

  4. Schistosome and liver fluke derived catechol-estrogens and helminth associated cancers

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Infection with helminth parasites remains a persistent public health problem in developing countries. Three of these pathogens, the liver flukes Clonorchis sinensis, Opisthorchis viverrini and the blood fluke Schistosoma haematobium, are of particular concern due to their classification as Group 1 carcinogens: infection with these worms is carcinogenic. Using liquid chromatography-mass spectrometry (LC-MS/MS approaches, we identified steroid hormone like (e.g. oxysterol-like, catechol estrogen quinone-like, etc. metabolites and related DNA-adducts, apparently of parasite origin, in developmental stages including eggs of S. haematobium, in urine of people with urogenital schistosomiasis, and in the adult stage of Opisthorchis viverrini. Since these kinds of sterol derivatives are metabolized to active quinones that can modify DNA, which in other contexts can lead to breast and other cancers, helminth parasite associated sterols might induce tumor-like phenotypes in the target cells susceptible to helminth parasite associated cancers, i.e. urothelial cells of the bladder in the case of urogenital schistosomiasis and the bile duct epithelia or cholangiocytes, in the case of O. viverrini and C. sinensis. Indeed we postulate that helminth induced cancers originate from parasite estrogen-host epithelial/urothelial cell chromosomal DNA adducts, and here we review recent findings that support this conjecture.

    To evaluate primary liver cancer death in the workers of China nuclear industry and to discuss the risk factors probably for making protection and cure measures, the workers of 11 units are surveyed from the time of foundation to the end of 1990 by groups, trades and sex, and the results are analyzed with the relevant physical examinations, the results in laboratory test, and some clinic epidemiological data concerned. The accumulative rough mortality is 19.20 x 10 -5 , standard mortality 10.09 x 10 -5 , the most is at the age of 35 to 54. SMR 1.00 (P > 0.05), RR value in uranium mines is 3.67 (P < 0.01) and others does not increase. The incidence of hepatomegalia and GPT rising are lower than or about 10%, while the incidence of HBsAg is lower than 8%, a middle-levelled infection in the country. And HBsAg incidence in liver cancer cases is 61.6% and chronic hepatitis in liver cancer cases is 53.4%. The liver cancer case increase in the workers in nuclear industry is not found, but significant increase is found in uranium mine workers; whereas there is no evidence that can be attributed to radiation operation, and the death risk may be considered mainly to be related to HBV infection, then chronic hepatitis or environment factors

    1984-09-01

    To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

    An increased risk of mortality from primary liver cancers among uranium miners has been observed in various studies. An analysis of the data from a German uranium miner cohort (the ‘Wismut cohort’) was used to assess the relationship with ionising radiation. To that end the absorbed organ dose due to high and low linear energy transfer radiation was calculated for 58 987 miners with complete information on radiation exposure from a detailed job–exposure matrix. 159 deaths from liver cancer were observed in the follow-up period from 1946 to 2003. Relative risk models with either linear or categorical dependence on high and low linear energy transfer radiation liver doses were fitted by Poisson regression, stratified on age and calendar year. The linear trend of excess relative risk in a model with both low and high linear transfer radiation is −0.8 (95% confidence interval (CI): −3.7, 2.1) Gy −1 and 48.3 (95% CI: −32.0, 128.6) Gy −1 for low and high linear energy transfer radiation, respectively, and thus not statistically significant for either dose. The increase of excess relative risk with equivalent liver dose is 0.57 (95% CI: −0.69, 1.82) Sv −1 . Adjustment for arsenic only had a negligible effect on the radiation risk. In conclusion, there is only weak evidence for an increase of liver cancer mortality with increasing radiation dose in the German uranium miners cohort considered. However, both a lack of statistical power and potential misclassification of primary liver cancer are issues. (paper)

    For esophageal cancer patients treated with neoadjuvant chemoradiotherapy (nCRT), restaging using F-18-fluorodeoxyglucose (FDG) positron emission tomography computed tomography (PET-CT) following nCRT can detect interval metastases, including liver metastases, in almost 10% of patients. However, in clinical practice, focal FDG liver uptake, unrelated to liver metastases, is observed after chemoradiotherapy. This radiation-induced liver injury (RILI) can potentially lead to overstaging. A systematic search for potential cases of RILI after (chemo)radiotherapy for esophageal cancer was performed in the electronic reports from all PET-CT scans made between 2006 and 2015 in our hospital. Additional data about potential cases were obtained from the electronic medical records. A literature review of RILI was also performed. Of 205 patients undergoing nCRT, 6 cases with localized increased FDG uptake in the caudate or left liver lobe following nCRT for esophageal cancer were identified. None of these patients had signs of liver metastases with additional imaging, during surgery, on biopsy, or during follow-up (range 11-46 months). At our institute, the incidence of RILI after neoadjuvant chemoradiotherapy for esophageal cancer was 3%. In the literature, RILI is described in about 8% of patients at the time of restaging. FDG-avid lesions occur in the high radiation dose area, usually corresponding to the caudate or left liver lobe. FDG accumulation in the caudate or left liver lobe after CRT in the area that received a high radiation dose may be caused by metastases or RILI. Awareness of the pitfall of high FDG uptake in RILI is crucial to avoid misinterpretation and overstaging. (orig.)

    Data on the potential effect of obesity and diabetes mellitus on survival after liver resection due to colorectal cancer (CRC) metastases are very limited. Patients undergoing liver resection for CRC metastases in a European institution in 2004-2011 were retrospectively enrolled. Relevant data, such as body mass index, extent of resection, chemotherapy, and perioperative outcome, were collected from medical records. The relation of obesity and diabetes mellitus with overall and disease-free survival was assessed using adjusted Cox models. Thirty of 207 patients (14.4%) included in the study were obese (BMI ≥30 kg/m(2)) and 25 (12%) had diabetes mellitus. Major hepatectomy was performed in 46%. Although both obese patients and those with diabetes had higher American Society of Anesthesiologist scores (P diabetes was significantly related to primary tumor characteristics, liver metastasis features, extent or radicality of resection, extrahepatic disease at hepatectomy, preoperative or postoperative oncologic therapy, or perioperative outcome (P > 0.05 for all). Patients were followed up for a median of 39 mo posthepatectomy (interquartile range, 13-56 mo). After adjustment for confounders, obesity was an independent predictor of improved (hazard ratio, 0.305, 95% confidence interval, 0.103-0.902) and diabetes of worse overall survival (hazard ratio, 3.298, 95% confidence interval, 1.306-8.330).

    Full Text Available BACKGROUND: Although numerous prognostic factors have been reported for colorectal cancer liver metastasis (CRLM, few studies have reported intraoperative blood loss (IBL effects on clinical outcome after CRLM resection. METHODS: We retrospectively evaluated the clinical and histopathological characteristics of 139 patients who underwent liver resection for CRLM. The IBL cutoff volume was calculated using receiver operating characteristic curves. Overall survival (OS and recurrence free survival (RFS were assessed using the Kaplan-Meier and Cox regression methods. RESULTS: All patients underwent curative resection. The median follow up period was 25.0 months (range, 2.1-88.8. Body mass index (BMI and CRLM number and tumor size were associated with increased IBL. BMI (P=0.01; 95% CI = 1.3-8.5 and IBL (P500mL were 71%, 33%, and 0%, respectively (P<0.01. RFS of patients within three IBL volumes at the end of the first year were 67%, 38%, and 18%, respectively (P<0.01. CONCLUSIONS: IBL during CRLM resection is an independent predictor of long term survival and tumor recurrence, and its prognostic value was confirmed by a dose-response relationship.

    As the biogenic magnetic nanomaterial, bacterial magnetic nanoparticles, namely magnetosomes, provide many advantages for potential biomedical applications. As such, interactions among magnetosomes and target cells should be elucidated to develop their bioapplications and evaluate their biocompatibilities. In this study, the interaction of magnetosomes and human liver cancer HepG2 cells was examined. Prussian blue staining revealed numerous stained particles in or on the cells. Intracellular iron concentrations, measured through inductively coupled plasma optical emission spectroscopy, increased with the increasing concentration of the magnetosomes. Transmission electron microscopy images showed that magnetosomes could be internalized in cells, mainly encapsulated in membrane vesicles, such as endosomes and lysosomes, and partly found as free particles in the cytosol. Some of the magnetosomes on cellular surfaces were encapsulated through cell membrane ruffling, which is the initiating process of endocytosis. Applying low temperature treatment and using specific endocytic inhibitors, we validated that macropinocytosis and clathrin-mediated endocytosis were involved in magnetosome uptake by HepG2 cells. Consequently, we revealed the interaction and intrinsic endocytic mechanisms of magnetosomes and HepG2 cells. This study provides a basis for the further research on bacterial magnetosome applications in liver diseases. - Highlights: • Bacterial magnetosomes interact with HepG2 cells in a dose-dependent manner. • Magnetosomes are wrapped by membrane ruffling on cell surface. • Internalized magnetosomes mainly localize in endosomes and lysosomes. • Macropinocytosis and CME are involved in the cellular uptake of magnetosomes.

    A series of 59 consecutive cases of histologically proven breast cancer were admitted.for radiotherapy. The group was mostly composed of stage III/TNM. The patients were studied with a scintillation camera and a 1600-channel analyser after i. v. injection of 2mCi of colloidal {sup 99m}Tc. Up to 104 counts were accumulated in one of the elements of the analyser matrix and were then transferred to computer-compatible punched tape. The data could be presented immediately in a number of different ways: (a) as conventional scintigraphic pictures on the camera's oscilloscope; (b) as nine pictures from the analyser's oscilloscope with 10, 20, 30... 90% of the counts erased; and (c) as one picture with those four selected levels of erase which were considered best, for a given case. In addition, progressive increase of exposure and defocusing of each level was possible. Examination with colloidal {sup 99m}Tc was found to be a safe method for the detection of malignant secondaries in the liver because of the low irradiation dose to the patient. The high radioactivity accumulated in the liver means a short examination time and the elimination of statistical fluctuations. Furthermore, the stored information enables the time-consuming work to be done in the patient's absence. (author)

    Transarterial chemoembolization (TACE) involves the emulsification of a chemotherapeutic agent in a viscous drug carrier, delivered intra-arterially to liver tumor for maximum effect. TACE reduces arterial inflow, diminishes washout of the chemotherapeutic agent, and decreases systemic exposure. Despite evidence of some clinical success with TACE, a new type of microspheres with drug-eluting capabilities may offer a precisely controlled and sustainable release of the chemotherapeutic agent into the tumor bed. In animal trials tumor necrosis (approaching 100%) was greatest at 7 days, with significantly lower plasma concentrations of doxorubicin than in control animals treated with doxorubicin intra-arterially. Clinically, drug-eluting microspheres loaded with doxorubicin, either at 75 mg/m 2 or at a fixed dose of 150 mg, were used recently and no severe disorders of the hepatic function were observed postprocedure, while a substantial reduction of the fetoprotein levels occurred. An interim analysis of the first 15 patients from the Hong Kong group at 3 months showed an objective response rate of 61.54% and 53.84% according to EASL criteria and RECIST criteria, respectively, and a survival rate of 93.3%. In this paper we present how to use microspheres loaded with doxorubicin and review their clinical value and preliminary performance for treatment of unresectable liver cancer

    -kB inhibition in liver cancer achieved by the IKK inhibitor curcumin, RNAi and specific peptide SN50. The effects on CSCs were assessed by analysis of Side Population (SP), sphere formation and tumorigenicity. Molecular changes were determined by RT-qPCR, global gene expression microarray, EMSA, and Western...... blotting. RESULTS: HCC cell lines exposed to curcumin exhibited differential responses to curcumin and were classified as sensitive and resistant. In sensitive lines, curcumin-mediated induction of cell death was directly related to the extent of NF-kB inhibition. The treatment also led to a selective CSC......-depletion as evidenced by a reduced SP size, decreased sphere formation, down-regulation of CSC markers and suppressed tumorigenicity. Similarly, NF-kB inhibition by SN50 and siRNA against p65 suppressed tumor cell growth. In contrast, curcumin-resistant cells displayed a paradoxical increase in proliferation...

    To investigate the application of Traditional Chinese Medicine Injections (TCMIs) for treatment of primary liver cancer (PLC). A literature review was conducted using PubMed/Medline, Cochrane Library Controlled Clinical Trials Database, China National Knowledge Infrastructure (CNKI), China Scientific Journal Database (CSJD) and China Biology Medicine (CBM). Online websites including journal websites and databases of ongoing trials, as well as some Traditional Chinese Medicine journals that are not indexed in the electronic databases were also searched. as adjunctive medication for the treatment of PLC could regulate patient immunity, reduce bone marrow suppression, relieve clinical symptoms, and improve quality of life, as well as control disease progression and prolong survival time. Within the limitations of this review, we conclude that application of TCMIs as adjunctive medication may provide benefits for patients with PLC. Further large, high-quality trials are warranted.

    Death, an unavoidable event in the human experience, causes physical as well as mental and spiritual suffering. This paper reports on a nursing experience giving spiritual care to a terminal liver cancer patient between January 17 and February 9, 2009. Eleven nursing logs were used as the source of data for daily information. During the care period, patient religious needs featured prominently, including his desire to become a Christian and his eagerness to know about and help in the arrangement of his funeral. Taking the initiative, the nurse helped link him with religious resources, arranged a minister for his baptism ceremony, had the priest explain funeral proceedings, and assisted with the completion of his entrusted plans. The function of this nursing care intervention was to provide a personal touch to a patient who was in desperate need of warm spiritual care. It is hoped that this report can help caregivers increase their sensitivity toward patient spiritual needs and enhance routine nursing care quality.

    Transcriptional repressor Pokemon is a critical factor in embryogenesis, development, cell proliferation, differentiation, and oncogenesis, thus behaving as an oncogene. Oncomine database suggests a potential correlation between the expressions of Pokemon and Sprouty1. This study investigated the regulatory role of Pokemon in Sprouty1 expression and the effect on liver cancer cell growth and proliferation, revealing a novel miR-21-mediated regulatory circuit. In normal (HL-7702) and cancer (QGY-7703) liver cell lines, Sprouty1 expression is inversely correlated with Pokemon levels. Targeted expression or siRNA-mediated silencing showed that Pokemon is a repressor of Sprouty1 expression at both mRNA and protein levels, but Pokemon cannot affect the promoter activity of Sprouty1. Sprouty1 is a target of miR-21 and interestingly, we found that miR-21 is up-regulated by Pokemon in liver cancer cells. Luciferase reporter assays showed that Pokemon up-regulated miR-21 transcription in a dose-dependent manner, and ChIP assay exhibited a direct binding of Pokemon to the miR-21 promoter at -747 to -399 bp. Site-directed mutagenesis of the GC boxes at -684 to -679 bp and -652 to -647 bp of miR-21 promoter abolished the regulatory activity by Pokemon. Furthermore, we found that the modulation of Pokemon and miR-21 expression affected the growth and proliferation of liver cancer cells QGY-7703. In summary, our findings demonstrate that Pokemon suppresses Sprouty1 expression through a miR-21-mediated mechanism, affecting the growth and proliferation of liver cancer cells. This study recognized miR-21 and Sprouty1 as novel targets of the Pokemon regulatory network. Copyright © 2013 Wiley Periodicals, Inc.

    Patients with liver cirrhosis represent a high risk group for colorectal surgery. The safety and effectiveness of laparoscopy in colorectal surgery for cirrhotic patients is not clear. The aim of this study was to compare the outcomes of laparoscopic colorectal surgery with those of open procedure for colorectal cancer in patients with liver cirrhosis. A total of 62 patients with cirrhosis who underwent radical resections for colorectal cancer from 2005 to 2014 were identified retrospectively from a prospective database according to the technique adopted (laparoscopic or open). Short- and long-term outcomes were compared between the two groups. Comparison of laparoscopic group and open group revealed no significant differences at baseline. In the laparoscopic group, the laparoscopic surgery was associated with reduced estimated blood loss (136 vs. 266 ml, p = 0.015), faster first flatus (3 vs. 4 days, p = 0.002) and shorter days to first oral intake (4 vs. 5 days, p = 0.033), but similar operative times (p = 0.856), number of retrieved lymph nodes (p = 0.400) or postoperative hospital stays (p = 0.170). Despite the similar incidence of overall complications between the two groups (50.0% vs. 68.8%, p = 0.133), we observed lower morbidities in laparoscopic group in terms of the rate of Grade II complication (20.0% vs. 50.0%, p = 0.014). Long-term of overall and Disease-free survival rates did not differ between the two groups. Laparoscopic colorectal surgery appears to be a safe and less invasive alternative to open surgery in some elective cirrhotic patients in terms of less blood loss or early recovery and does not result in additional harm in terms of the postoperative complications or long-term oncological outcomes.

    Highlights: •LRH-1 is an orphan nuclear receptor that regulates tumor proliferation. •In breast cancer, high mRNA expression is associated with ER+ status. •In ER−ve cells, despite very low mRNA, we found abundant LRH-1 protein. •Our data show distinctly different LRH-1 protein isoforms in ER− and ER+ breast cancer cells. •This is due to differences in LRH-1 mRNA and protein stability rates. -- Abstract: The expression of orphan nuclear receptor Liver Receptor Homolog-1 (LRH-1) is elevated in breast cancer and promotes proliferation, migration and invasion in vitro. LRH-1 expression is regulated by oestrogen (E 2 ), with LRH-1 mRNA transcript levels higher in oestrogen receptor α (ERα) positive (ER+) breast cancer cells compared to ER− cells. However, the presence of LRH-1 protein in ER− cells suggests discordance between mRNA transcript levels and protein expression. To understand this, we investigated the impact of mRNA and protein stability in determining LRH-1 protein levels in breast cancer cells. LRH-1 transcript levels were significantly higher in ER+ versus ER− breast cancer cells lines; however LRH-1 protein was expressed at similar levels. We found LRH-1 mRNA and protein was more stable in ER− compared to ER+ cell lines. The tumor-specific LRH-1 variant isoform, LRH-1v4, which is highly responsive to E 2 , showed increased mRNA stability in ER− versus ER+ cells. In addition, in MCF-7 and T47-D cell lines, LRH-1 total mRNA stability was reduced with E 2 treatment, this effect mediated by ERα. Our data demonstrates that in ER− cells, increased mRNA and protein stability contribute to the abundant protein expression levels. Expression and immunolocalisation of LRH-1 in ER− cells as well as ER− tumors suggests a possible role in the development of ER− tumors. The modulation of LRH-1 bioactivity may therefore be beneficial as a treatment option in both ER− and ER+ breast cancer

    Full Text Available Abstract Background Pancreatic cancer is the fourth leading cause of tumour death in the western world. However, appropriate tumour models are scarce. Here we present a syngeneic murine pancreatic cancer model using 7 Tesla MRI and evaluate its clinical relevance and applicability. Methods 6606PDA murine pancreatic cancer cells were orthotopically injected into the pancreatic head. Liver metastases were induced through splenic injection. Animals were analyzed by MRI three and five weeks following injection. Tumours were detected using T2-weighted high resolution sequences. Tumour volumes were determined by callipers and MRI. Liver metastases were analyzed using gadolinium-EOB-DTPA and T1-weighted 3D-Flash sequences. Tumour blood flow was measured using low molecular gadobutrol and high molecular gadolinium-DTPA. Results MRI handling and applicability was similar to human systems, resolution as low as 0.1 mm. After 5 weeks tumour volumes differed significantly (p 3+/-243 mm3 with MRI (mean 918 mm3+/-193 mm3 with MRI being more precise.

    Objective To explore the effect of overexpressed liver kinase B1(LKB1) on the proliferation of lung cancer cell lines. Methods The expression levels of LKB1 and PTEN in A549, NCI-H23, NCI-H157, XWLC-05, NCI-H446 lung cancer cells were detected by immunocytochemistry (ICC) and Western blotting. Plasmid pcDNA3.1 + -LKB1 and empty vector pcDNA3.1 + -null were separately transfected into the above five cell lines, and then the expression of LKB1 mRNA and protein were determined by quantitative real-time PCR and Western blotting, respectively. Finally, CCK-8 assay was used to analyze the proliferation ability of the transfected cells. Results LKB1 and PTEN were positive in NCI-H23 cells; LKB1 was negative while PTEN was positive in A549 and NCI-H446 cells; both LKB1 and PTEN were negative in NCI-H157 and XWLC-05 cells. Quantitative real-time PCR and Western blotting showed that the expression level of LKB1 significantly increased in the above cell lines transfected with plasmid pcDNA3.1 + -LKB1 compared with the ones with empty vector pcDNA3.1 + -null. Besides, CCK-8 assay showed that the overexpression of LKB1 in the lung cancer cells transfected with pcDNA3.1 + -LKB1 had an obvious inhibitory effect on cell proliferation. Conclusion The expression of LKB1 is down-regulated in most of the lung cell lines to different extent and the over-expression of LKB1 can remarkably inhibit the proliferation ability of lung cancer cell lines.

    The aim of the study was to elucidate the mechanism by which advanced glycation end products (AGEs) promote cell proliferation in liver cancer cells.We treated liver cancer HepG2 cells with 200 mg/L AGEs or bovine serum albumin (BSA) and assayed for cell viability, cell cycle, and apoptosis. We performed real-time PCR and Western blot analysis for RNA and protein levels of carbohydrate responsive element-binding protein (ChREBP) in AGEs- or BSA-treated HepG2 cells. We analyzed the level of reactive oxygen species (ROS) in HepG2 cells treated with AGEs or BSA.We found that increased S-phase cell percentage and decreased apoptosis contributed to AGEs-induced liver cancer cell proliferation. Real-time PCR and Western blot analysis showed that AGEs stimulated RNA and protein levels of ChREBP, a transcription factor promoting glycolysis and maintaining cell proliferation in liver cancer cells. Intriguingly, the level of ROS was higher in AGEs-treated liver cancer cells. Treating liver cancer cells with antioxidant N-acetyl cystein (NAC) partly blocked AGEs-induced ChREBP expression and cell proliferation.Our results suggest that the AGEs-ROS-ChREBP pathway plays a critical role in promoting ChREBP expression and liver cancer cell proliferation.

    Full Text Available One-carbon metabolism (folate metabolism is considered important in carcinogenesis because of its involvement in DNA synthesis and biological methylation reactions. We investigated the associations of single nucleotide polymorphisms (SNPs in folate metabolic pathway and the risk of three GI cancers in a population-based case-control study in Taixing City, China, with 218 esophageal cancer cases, 206 stomach cancer cases, 204 liver cancer cases, and 415 healthy population controls. Study participants were interviewed with a standardized questionnaire, and blood samples were collected after the interviews. We genotyped SNPs of the MTHFR, MTR, MTRR, DNMT1, and ALDH2 genes, using PCR-RFLP, SNPlex, or TaqMan assays. To account for multiple comparisons and reduce the chances of false reports, we employed semi-Bayes (SB shrinkage analysis. After shrinkage and adjusting for potential confounding factors, we found positive associations between MTHFR rs1801133 and stomach cancer (any T versus C/C, SB odds-ratio [SBOR]: 1.79, 95% posterior limits: 1.18, 2.71 and liver cancer (SBOR: 1.51, 95% posterior limits: 0.98, 2.32. There was an inverse association between DNMT1 rs2228612 and esophageal cancer (any G versus A/A, SBOR: 0.60, 95% posterior limits: 0.39, 0.94. In addition, we detected potential heterogeneity across alcohol drinking status for ORs relating MTRR rs1801394 to esophageal (posterior homogeneity P = 0.005 and stomach cancer (posterior homogeneity P = 0.004, and ORs relating MTR rs1805087 to liver cancer (posterior homogeneity P = 0.021. Among non-alcohol drinkers, the variant allele (allele G of these two SNPs was inversely associated with the risk of these cancers; while a positive association was observed among ever-alcohol drinkers. Our results suggest that genetic polymorphisms related to one-carbon metabolism may be associated with cancers of the esophagus, stomach, and liver.

    2012-01-01

    The mouse alpha-fetoprotein (AFP) gene is abundantly expressed in the fetal liver, normally silent in the adult liver but is frequently reactivated in hepatocellular carcinoma. The basis for AFP expression in the fetal liver has been studied extensively. However, the basis for AFP reactivation during hepatocarcinogenesis is not well understood. Two novel factors that control postnatal AFP repression, Zhx2 and Zbtb20, were recently identified. Here, we review the transcription factors that regulate AFP in the fetal liver, as well as Zhx2 and Zbtb20, and raise the possibility that the loss of these postnatal repressors may be involved in AFP reactivation in liver cancer.

Given that all intracellular/secreted proteins are processed into peptides and presented by class I MHC on the surface of tumor cells, we used alpha-fetoprotein (AFP), a specific liver cancer marker, as an example to determine whether peptide-MHC complexes can be targets for CAR T-cell therapy against solid tumors. We generated a fully human chimeric antigen receptor, ET1402L1-CAR (AFP-CAR), with exquisite selectivity and specificity for the AFP 158-166 peptide complexed with human leukocyte antigen (HLA)-A*02:01. We report that T cells expressing AFP-CAR selectively degranulated, released cytokines, and lysed liver cancer cells that were HLA-A*02:01 + /AFP + while sparing cells from multiple tissue types that were negative for either expressed proteins. In vivo, intratumoral injection of AFP-CAR T cells significantly regressed both Hep G2 and AFP 158 -expressing SK-HEP-1 tumors in SCID-Beige mice (n = 8 for each). Moreover, intravenous administration of AFP-CAR T cells in Hep G2 tumor-bearing NSG mice lead to rapid and profound tumor growth inhibition (n = 6). Finally, in an established intraperitoneal liver cancer xenograft model, AFP-CAR T cells showed robust antitumor activity (n = 6). This study demonstrates that CAR T-cell immunotherapy targeting intracellular/secreted solid tumor antigens can elicit a potent antitumor response. Our approach expands the spectrum of antigens available for redirected T-cell therapy against solid malignancies and offers a promising new avenue for liver cancer immunotherapy.

    Full Text Available Colorectal cancer (CRC is the third most common malignancy in males and the second most common in females worldwide. Distant metastases have a strong negative impact on the prognosis of CRC patients. The most common site of CRC metastases is the liver. Both disease progression and metastasis have been related to the patient's peripheral blood monocyte count. We therefore performed a case-control study to assess the relationship between the preoperative peripheral blood monocyte count and colorectal liver metastases (CRLM.Clinical data from 117 patients with colon cancer and 93 with rectal cancer who were admitted to the Chinese People's Liberation Army General Hospital (Beijing, China between December 2003 and May 2015 were analysed retrospectively, with the permission of both the patients and the hospital.Preoperative peripheral blood monocyte counts, the T and N classifications of the primary tumour and its primary site differed significantly between the two groups (P 0.505 × 109 cells/L, high T classification and liver metastasis were independent risk factors for 5-year OS (RR: 2.737, 95% CI: 1.573~ 4.764, P <0.001; RR: 2.687, 95%CI: 1.498~4.820, P = 0.001; RR: 4.928, 95%CI: 2.871~8.457, P < 0.001.The demonstrated association between preoperative peripheral blood monocyte count and liver metastasis in patients with CRC recommends the former as a useful predictor of postoperative prognosis in CRC patients.

    The inoperability input-output model (IIM) has been used for analyzing disruptions due to man-made or natural disasters that can adversely affect the operation of economic systems or critical infrastructures. Taking economic perturbation for each sector as inputs, the IIM provides the degree of economic production impacts on all industry sectors as the outputs for the model. The current version of the IIM does not provide a separate analysis for the international trade component of the inoperability. If an important port of entry (e.g., Port of Los Angeles) is disrupted, then international trade inoperability becomes a highly relevant subject for analysis. To complement the current IIM, this article develops the International Trade-IIM (IT-IIM). The IT-IIM investigates the resulting international trade inoperability for all industry sectors resulting from disruptions to a major port of entry. Similar to traditional IIM analysis, the inoperability metrics that the IT-IIM provides can be used to prioritize economic sectors based on the losses they could potentially incur. The IT-IIM is used to analyze two types of direct perturbations: (1) the reduced capacity of ports of entry, including harbors and airports (e.g., a shutdown of any port of entry); and (2) restrictions on commercial goods that foreign countries trade with the base nation (e.g., embargo).

    Economists have long conceptualized and modeled the inherent interdependent relationships among different sectors of the economy. This concept paved the way for input-output modeling, a methodology that accounts for sector interdependencies governing the magnitude and extent of ripple effects due to changes in the economic structure of a region or nation. Recent extensions to input-output modeling have enhanced the model's capabilities to account for the impact of an economic perturbation; two such examples are the inoperability input-output model((1,2)) and the dynamic inoperability input-output model (DIIM).((3)) These models introduced sector inoperability, or the inability to satisfy as-planned production levels, into input-output modeling. While these models provide insights for understanding the impacts of inoperability, there are several aspects of the current formulation that do not account for complexities associated with certain disasters, such as a pandemic. This article proposes further enhancements to the DIIM to account for economic productivity losses resulting primarily from workforce disruptions. A pandemic is a unique disaster because the majority of its direct impacts are workforce related. The article develops a modeling framework to account for workforce inoperability and recovery factors. The proposed workforce-explicit enhancements to the DIIM are demonstrated in a case study to simulate a pandemic scenario in the Commonwealth of Virginia.

  19. The global geographical overlap of aflatoxin and hepatitis C: Controlling risk factors for liver cancer worldwide

    About 85% of hepatocellular carcinoma (HCC, liver cancer) cases occur in low-income countries, where the risk factors of dietary aflatoxin exposure and chronic hepatitis B and C (HBV and HCV) viral infection are common. While studies have shown synergism between aflatoxin and HBV in causing HCC, much less is known about whether aflatoxin and HCV synergize similarly. From an exposure perspective, we examine whether there is a geographical overlap in populations worldwide exposed to high dietary aflatoxin levels and with high HCV prevalence. While HCV is one of the most important risk factors for HCC in high-income nations (where aflatoxin exposure is low), we find that HCV prevalence is much higher in Africa and Asia, where aflatoxin exposure is also high. However, within a given world region, there are some inconsistencies regarding exposure and cancer risk. Therefore, there is a need to control risk factors such as aflatoxin and hepatitis viruses in a cost-effective manner to prevent global HCC, while continuing to evaluate biological mechanisms by which these risk factors interact to increase HCC risk.

    Full Text Available Approximately one-third of patients with colorectal cancer are estimated to be diagnosed with synchronous liver metastasis (LM. The only method to get cured is to achieve curative resection for both primary and LM. When it comes to locally advanced rectal cancer with synchronous LM, determination of the treatment strategy for each individual is a quite complex procedure, because it demands sophisticated consideration for both local and systemic control. Timing for the application of systemic chemotherapy (CTx, determination of a chemotherapeutic agent, radiation dose and fractions, and sequencing of preoperative treatment and surgeries are all essential components for establishing optimal treatment strategies for the patients with this disease. In this article, treatment strategies proposed in the literature will be reviewed in the light of oncologic outcomes and treatment toxicity with their possible advantages and disadvantages. Owing to a lack of concrete evidences for the best strategy, this article can guide authors to a better way of determining more tailored treatment for each individual.

    Gastric cancer (GC) currently prevails as the second cause of death by malignancy worldwide. Estimations suggest that 35 % of affected patients appear with synchronous distant metastases. The vast majority of patients present with hepatic metastatic disease, sometimes accompanied by synchronous peritoneal and lung dissemination. The disease mostly remains asymptomatic at an early stage, with few reported cases of incidental abdominal discomfort. As the cancer advances, symptoms such as nausea or vomiting arise, along with indigestion and dysphagia, blood loss in the form of melena or hematemesis, as well as anorexia and weight loss. Having spread to the liver, it also causes jaundice due to hepatomegaly and general inanition. Despite recent research on the therapeutic strategies against GC metastatic disease, surgical resection appears the only potentially curative approach. Unfortunately, the majority of patients are not eligible to undergo surgical intervention. With regard to treatment modalities of the advanced stage disease, the role of metastasectomy is still debatable and quite unclear, while prolonged survival was succeeded only under certain specific circumstances. Systemic chemotherapy remains however another option, as well as local management in the form of cryotherapy, radiofrequency ablation, or transcatheter arterial chemoembolization. The aims of this review were to evaluate the results of surgical treatment for metastatic GC with special reference to the extent of its histological spread and to present the recent literature in order to provide an update on the current concepts of advanced surgical management of this entity. Relevant publications in the last two decades are briefly reviewed.

    Primary liver cancer (PLC) is one of the most common malignancies worldwide with increasing incidence and accounts for the third leading cause of cancer-related mortality. Traditional morphopathology primarily emphasizes qualitative diagnosis of PLC, which is not sufficient to resolve the major concern of increasing the long-term treatment efficacy of PLC in clinical management for the modern era. Since the beginning of the 21st century, molecular pathology has played an active role in the investigation of the evaluation of the metastatic potential of PLC, detection of drug targets, prediction of recurrence risks, analysis of clonal origins, evaluation of the malignancy trend of precancerous lesions, and determination of clinical prognosis. As a result, many new progresses have been obtained, and new strategies of molecular-pathological diagnosis have been formed. Moreover, the new types of pathobiological diagnosis indicator systems for PLC have been preliminarily established. These achievements provide valuable molecular pathology-based guide for clinical formulation of individualized therapy programs for PLC. This review article briefly summarizes some relevant progresses of molecular-pathological diagnosis of PLC from the perspective of clinical translational application other than basic experimental studies.

    A case is a 55-year-old woman. We noticed the right breast lump in May 2006. It was papillotubular carcinoma, ER(-), PgR -), HER2 (3+) by needle biopsy. The patient was introduced to our department in November 2006 for a close inspection and treatment. The palpation showed a mass without a firm flexibility, which was a border indistinctness of about 2 cm in size in the right AB area. We did not find a distant metastasis either. We operated for Bt+Ax (level II) in December. It was T2N0M0, stage IIA papillotubular carcinoma, ER(-), PgR(-), HER2 (3+) with histopathology. We recommended an adjuvant therapy but the patient refused. Since then we followed her up. After two years from the operation, multiple metastases were observed to the liver, FEC therapy was started. CT revealed that metastasized tumors were disappeared after six courses of treatment. Echography obtained cCR. Generally speaking, chemotherapy was effective for breast cancer as we compared it to endemic cancer of other organs. Meanwhile, it has been reported that many kinds of newly developed medicines for the treatment are available and effective. On the other hand, a selection of therapeutic drugs could be a problem for metastasized organs.

    With increased interest in non-alcoholic steatohepatitis, its common co-morbid condition, obesity, has recently attracted much attention as a risk factor for liver cancer. Recent studies also suggest that obesity may play a role in the development of liver cancer in alcoholic cirrhosis or viral hepatitis and in the general population. We systematically reviewed epidemiologic studies on overweight/obesity and liver cancer among Japanese populations. Original data were obtained by searching the MEDLINE (PubMed) and Ichushi databases, complemented by manual searches. The evaluation was performed in terms of the magnitude of association in each study and the strength of evidence ('convincing', 'probable', 'possible' or 'insufficient'), together with biologic plausibility. Among nine cohort studies identified, five (four on patients with chronic liver disease and one on local residents) reported a weak to strong positive association, while four (one on patients with hepatitis B and three on local residents) found no association [summary relative risk for one unit increase in body mass index (kg/m 2 ) 1.07, 95% confidence interval 1.03-1.10]. All three case-control studies identified (two on cirrhotic patients and one on atomic bomb survivors) reported a strong positive association (summary relative risk 1.31, 95% confidence interval 1.12-1.53). Overall, the summary relative risk was estimated at 1.13 (95% confidence interval 1.07-1.20), and overweight/obese individuals had a relative risk of 1.74 (95% confidence interval 1.33-2.28) compared with those who had normal/low weight. We conclude that overweight or obesity 'probably' increases the risk of primary liver cancer, to a moderate degree, among the Japanese population. (author)

    Metformin, one of the most commonly used drugs for patients with type 2 diabetes, recently has received much attention regarding its anti-cancer action. It is thought that the suppression of mTOR signaling is involved in metformin's anti-cancer action. Although liver cancer is one of the most responsive types of cancer for reduction of incidence by metformin, the molecular mechanism of the suppression of mTOR in liver remains unknown. In this study, we investigated the mechanism of the suppressing effect of metformin on mTOR signaling and cell proliferation using human liver cancer cells. Metformin suppressed phosphorylation of p70-S6 kinase, and ribosome protein S6, downstream targets of mTOR, and suppressed cell proliferation. We found that DEPTOR, an endogenous substrate of mTOR suppression, is involved in the suppressing effect of metformin on mTOR signaling and cell proliferation in human liver cancer cells. Metformin increases the protein levels of DEPTOR, intensifies binding to mTOR, and exerts a suppressing effect on mTOR signaling. This increasing effect of DEPTOR by metformin is regulated by the proteasome degradation system; the suppressing effect of metformin on mTOR signaling and cell proliferation is in a DEPTOR-dependent manner. Furthermore, metformin exerts a suppressing effect on proteasome activity, DEPTOR-related mTOR signaling, and cell proliferation in an AMPK-dependent manner. We conclude that DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action in liver, and could be a novel target for anti-cancer therapy. - Highlights: • We elucidated a novel pathway of metformin's anti-cancer action in HCC cells. • DEPTOR is involved in the suppressing effect of metformin on mTOR signaling. • Metformin increases DEPTOR protein levels via suppression of proteasome activity. • DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action.

    Background/Aim: The sacrifice of a major hepatic vein can cause hepatic venous congestion (HVC). We evaluated the effects of HVC on regional liver function using the liver uptake value (LUV), that was calculated from 99m Tc-labeled-galactosyl-human-serum-albumin ( 99m Tc-GSA) single-photon emission computed tomography (SPECT) /contrast-enhanced computed tomography (CE-CT) fused images. Patients and Methods: Sixty-two patients underwent 99m Tc-GSA SPECT/CE-CT prior to hepatectomy for liver cancer and at 7 days after surgery were divided into groups with (n=8) and without HVC (n=54). In the HVC group, CT volume (CTv) and LUV were separately calculated in both congested and non-congested areas. Results: The remnant LUV/CTv of the HVC group was significantly smaller than that of the non-HVC group (pliver function per unit volume in the congested areas was approximately 40% of that in the non-congested areas.

    Full Text Available Liver kinase B1 (LKB1, known as a serine/threonine kinase, has been identified as a critical cancer suppressor in many cancer cells. It is a master upstream kinase of 13 AMP-activated protein kinase (AMPK-related protein kinases, and possesses versatile biological functions. LKB1 gene is mutated in many cancers, and its protein can form different protein complexes with different cellular localizations in various cell types. The expression of LKB1 can be regulated through epigenetic modification, transcriptional regulation and post-translational modification. LKB1 dowcnstream pathways mainly include AMPK, microtubule affinity regulating kinase (MARK, salt-inducible kinase (SIK, sucrose non-fermenting protein-related kinase (SNRK and brain selective kinase (BRSK signalings, etc. This review, therefore, mainly discusses recent studies about the expression, regulation, downstream signaling and cancer suppressive function of LKB1, which can be helpful for better understanding of this molecular and its significance in cancers.

    Full text: In this paper we present our early experience with a new radio-conjugate, namely rhenium-188 HDD Lipiodol (Re-188 lipiodol). Imported radiopharmaceuticals are generally expensive, particularly for developing countries. A Tungsten (W-188-Re 188) generator obtained from ORNL (Oak Ridge National Laboratory, Tennessee, USA) allows us on-site production of a beta emitting therapeutic isotope (Re-188) for up to 6 months from a single generator. The objectives of this study were to establish the safety of trans-arterial Re-188 lipiodol in patients with inoperable HCC, and determine the adverse effects and efficacy for this radio-conjugate treatment in a multi-center study of patients with advanced HCC. A multi-center study was sponsored by the International Atomic Energy Agency (Vienna) to assess the safety and efficacy of trans-arterial Re-188 HDD conjugated lipiodol (radio-conjugate) in the treatment of patients with inoperable hepatocellular carcinoma (HCC), The radio-conjugate was prepared by using a HDD (4-hexadecyl 1-2, 9, 9-tetramethyl-4, 7-diaza-1, 10-decanethiol) kit developed in Korea, and lipiodol. Over a period of eighteen months seventy patients received at least one treatment of radio-con
