- The Impact of Early Dermatologic Events in the Survival of Patients with Hepatocellular Carcinoma Treated with Sorafenib(2017) BRANCO, Fernanda; ALENCAR, Regiane S. M.; VOLT, Fernanda; SARTORI, Giovana; DODE, Andressa; KIKUCHI, Luciana; TANI, Claudia M.; CHAGAS, Aline L.; PFIFFER, Tulio; HOFF, Paulo; CARRILHO, Flair J.; MATTOS, Angelo Alves deBackground and Aims. The presence of dermatologic reaction as an adverse event to sorafenib treatment in patients with unresectable hepatocellular carcinoma has been indicated as a prognostic factor for survival in a recent prospective analysis. To date, this is the only clinical predictor of treatment response , which can be eavaluated earlier in the treatment and, therefore, contribute to a better and more individualized patient management. Material and methods. This retrospective study included 127 patients treated with sorafenib under real-life practice conditions in two hepatology reference centers in Brazil, Demographic data, disease/medical history and time of sorafenib administration as well as adverse events related to the medication were recorded in a database Results. Cirrhosis was present in 94% of patients, 85.6% were child-pugh A, 80.3%BCLC-C,81% had vascular invasion and/or extrahepatic spread and 95% had a performance status 0 to 1. The median duration of treatment was 10.1 months (range: 0.1-47 months). The most common adverse event within the first 60 days of treatment were diarrhea (62.2%) and dermatological reaction (42%). The median overall survival for the cohort was 20 months, and it was higher for patients who developed dermatological reactions within the first 60 days compared to those who did not present this adverse event. Conclusion. This retrospective analysis showed the use of sorafenib in patients selected according to BCLC staging, and it is the first external validation of early dermatologic adverse events as a predictor of overall survival in patients with advanced hepatocellular carcinoma.
- Hepatocellular Carcinoma Related to Schistosoma mansoni Infection: Case Series and Literature Review(2015) TODA, Karla Sawada; KIKUCHI, Luciana; CHAGAS, Aline Lopes; TANIGAWA, Ryan Yukimatsu; PARANAGUA-VEZOZZO, Denise Cerqueira; PFIFFER, Tulio; ROCHA, Manoel de Souza; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair JoseBackground and Aims: Schistosomiasis is a major chronic disease of humans in endemic regions, and infected individuals may develop a spectrumof pathology, including hepatic fibrosis, hepatosplenomegaly, and portal hypertension. Hepatocellular carcinoma (HCC) is considered the fifth most common cancer in the world, and there is limited and controversial evidence suggesting that Schistosoma mansoni infection may be a possible risk factor for HCC. The aim of this study was to report a case series of patients with HCC and S. mansoni infection and to conduct a literature review on the topic. Methods: From January 2002 to January 2015, an institutional database was screened retrospectively to identify patients with HCC and S. mansoni infection at a single center in the Department of Gastroenterology of University of Sao Paulo School of Medicine and Hospital das Clinicas, Brazil. Results: Seven cases were included. The mean age of patients was 62.1 +/- 10.3 years; six (85.7%) were male and one (14.3%) was female. All cases had positive epidemiology, coming from endemic areas of S. mansoni infection in Brazil, and four (57.1%) had previous complications (upper gastrointestinal bleeding) related toportal hypertension or surgery intervention (splenectomy) performed more than 10 years before the HCC diagnosis. Nontumoral portal vein thrombosis was identified in five (71.4%) patients. All patients had negative serology for HCV, and four (57.1%) had positivity of HBVcore antibodies without evidence of viral replication. According to BCLC staging, one (14.3%) patient was BCLC A and received TACE instead of RFA because HCC size was >30 mm; three (42.8%) BCLC B patients received sorafenib instead of local regional treatment due to the presence of nontumoral TPV. During follow-up, all patients developed tumoral progression and died. Conclusions: It remains unclear if S. mansoni infection alone has carcinogenic potential. The available literature indicates that S. Mansoni, in the presence of HBV and HCV infections, likely acts as a cofactor for the hepatic lesion and potentiates injury.
- GUIDELINE FOR THE MANAGEMENT OF BILE DUCT CANCERS BY THE BRAZILIAN GASTROINTESTINAL TUMOR GROUP(2016) RIECHELMANN, Rachel; COUTINHO, Anelisa K; WESCHENFELDER, Rui F; ANDRADE DE PAULO, Gustavo; FERNANDES, Gustavo dos Santos; GIFONI, Markus; OLIVEIRA, Maria de Lourdes; GANSL, Rene; GIL, Roberto; LUERSEN, Gustavo; LUCAS, Lucio; REISNER, Marcio; VIEIRA, Fernando Meton; MACHADO, Marcel Autran; MURAD, Andre; OSVALDT, Alessandro; BRANDÃO, Miguel; CARVALHO, Elisangela; SOUZA, Tulio; PFIFFER, Tulio; PROLLA, GabrielABSTRACT The Brazilian Gastrointestinal Tumor Group developed guidelines for the surgical and clinical management of patients with billiary cancers. The multidisciplinary panel was composed of experts in the field of radiology, medical oncology, surgical oncology, radiotherapy, endoscopy and pathology. The panel utilized the most recent literature to develop a series of evidence-based recommendations on different treatment and diagnostic strategies for cholangiocarcinomas and gallbladder cancers.
