Factors affecting survival after concurrent chemoradiation therapy for advanced hepatocellular carcinoma: a retrospective study.

ABSTRACT: Concurrent chemoradiation therapy (CCRT) followed by hepatic arterial infusional chemotherapy (HAIC) was reported to be effective for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. However, transarterial chemoembolization (TACE) is not preferred in this setting. The aim of this study was to assess the factors affecting survival after CCRT, including additional TACE during repeated HAIC.Thirty-eight patients who underwent CCRT as the initial treatment for Barcelona Clinic Liver Cancer stage C HCC with vascular invasion between 2009 and 2016 were reviewed retrospectively. During CCRT, 5-fluorouracil (5-FU) was infused via chemoport during the first and last five days of five weeks of external beam radiation therapy. After CCRT, repeated HAIC with cisplatin and 5-FU was performed monthly. Nineteen patients (50%) underwent additional TACE between repeated HAICs. Factors related to overall survival and progression free survival (PFS) were analyzed.The mean age of patients was 55 years (male:female, 33:5). Underlying liver diseases were hepatitis B, hepatitis C and non-B/C in 29, 1 and 8 patients, respectively. The median radiation dose was 4500 cGy. The objective response (OR) rate at one months after CCRT was 36.8%. The median PFS was 7.4 (range, 1.8 - 32.1) months. The median overall survival was 11.6 (range 2.8-65.7) months. Achieving an OR after CCRT (hazard ratio [HR], 0.028; P < 0.001), additional TACE (HR, 0.134, P < 0.001), and further rounds of HAIC (HR, 0.742, P = 0.001) were independent significant factors related to overall survival. The overall survival duration of patients with an OR after CCRT (median 44.2 vs. 6.6 months, P < 0.001) and additional TACE (median 19.8 vs. 9.1 months, P = 0.001) were significantly greater than those without an OR after CCRT or additional TACE.Patients who achieved an OR after CCRT, underwent additional TACE, and were subjected to repeated rounds of HAIC following CCRT showed better survival after CCRT for advanced stage of HCC with vascular invasion. A further prospective study is needed to confirm the positive effect of additional TACE after CCRT.

Project description:Background & aimsWith the rising prevalence of alcoholism, obesity and metabolic syndrome, steatohepatitis will become the leading cause of end-stage liver disease and hepatocellular carcinoma in the United States by 2025. Patients with non-alcoholic steatohepatitis and alcoholic liver disease have similar clinical and histopathological presentations, whether these similarities persist in non-alcoholic steatohepatitis and alcoholic liver disease patients with hepatocellular carcinoma remains unknown.MethodsA retrospective analysis of the clinical features of adult patients from a large transplant center who underwent liver transplantation for steatohepatitis due to non-alcoholic steatohepatitis and alcoholic causes (alcoholic liver disease) between 1/1/02 and 1/1/12 was performed. Clinical features, explant histopathology, and clinical outcomes were compared.ResultsHepatocellular carcinoma was present in 80 of 317 patients, who underwent liver transplantation for steatohepatitis with equivalent distribution in non-alcoholic steatohepatitis and alcoholic liver disease patients (24% vs 26%; P = 0.8). On multivariate analysis, significant predictors of hepatocellular carcinoma included age, ethnicity (Hispanic), and diabetes, but not BMI, hypertension or smoking. A lower risk of hepatocellular carcinoma was associated with a clinical history of hyperlipidemia. Clinical parameters were similar between patients with alcoholic liver disease - hepatocellular carcinoma and non-alcoholic steatohepatitis-hepatocellular carcinoma, except sex and presence of metabolic syndrome. non-alcoholic steatohepatitis-hepatocellular carcinoma livers retained histopathological features of non-alcoholic steatohepatitis such as ballooning and Mallory bodies, while alcoholic liver disease-hepatocellular carcinoma livers did not. There were no significant differences in hepatocellular carcinoma recurrence rates or post-transplant overall survival.ConclusionsWe report the largest single-center study evaluating clinical, histopathological and outcome measures of patients undergoing liver transplantation for steatohepatitis. Older patients, diabetics, and Hispanics may warrant more frequent cancer screening due to increased risk of hepatocellular carcinoma.

Project description:BackgroundDefinitive treatment of primary middle ear lymphoepithelial carcinoma (LEC) is not well established owing to the rarity of this disease entity. We report a case of locally advanced primary middle ear LEC treated with concurrent chemoradiation, with good oncologic outcomes.Case presentationA 46 year-old female of Cantonese (Southern Chinese) descent presented with a four-month history of left sided hearing loss and non-pulsatile tinnitus, associated with progressive ipsilateral facial weakness. She had a left facial palsy (House-Brackmann 2) which then deteriorated to complete palsy over 2 weeks. Otoscopic examination of the left ear revealed a red-hued mass replacing the tympanic membrane. There was no cervical lymphadenopathy. Fibreoptic nasoendoscopy was unremarkable. Pure tone audiometry revealed profound mixed left hearing loss with type B impedance. Computed tomography of the temporal bone showed an ill-defined left middle ear mass with erosion of the malleus, tegmen tympani and facial canal. Magnetic Resonance Imaging showed an avidly enhancing lesion involving the dura of the left middle cranial fossa, tympanic and labyrinthine portions of the facial nerve. This mass extended into the apex of the left internal acoustic canal and basal turn of the cochlea. Histopathology confirmed EBV-positive primary middle ear LEC. Concurrent chemoradiation comprising 70Gy of intensity-modulated radiation therapy and 3 cycles of concurrent Cisplatin based chemotherapy over a 6 week period was administered. The patient achieved near-complete disease resolution on 3 month post-treatment imaging. Serum EBV DNA titres declined to undetectable levels and the patient is disease-free at 18 months post-diagnosis.Discussion and conclusionConcurrent chemoradiation with curative intent may be a viable treatment option for locally advanced middle ear LEC not amenable to surgical resection due to expected surgical morbidity. It confers good oncologic outcomes that mimic the response in other head and neck EBV-related lymphoepithelial carcinomas.
