    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 de
    Background 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.

    Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.

    Expression of ERCC1, Bcl-2, Lin28a, and Ki-67 as biomarkers of response to first-line platinum-based chemotherapy in patients with high-grade extrapulmonary neuroendocrine carcinomas or small cell lung cancer
    (2017) REGO, Juliana Florinda de M; MEDEIROS, Raphael Salles Scortegagna de; BRAGHIROLI, Maria Ignez; GALVAO, Breno; BEZERRA NETO, Joao Evangelista; MUNHOZ, Rodrigo Ramella; GUERRA, Juliana; NONOGAKI, Suely; KIMURA, Lidia; PFIFFER, Tulio Eduardo; CASTRO JR., Gilberto de; HOFF, Paulo Marcelo; FILHO, Duilio Rocha; COSTA, Frederico Perego; RIECHELMANN, Rachel P.
    Background: Small cell lung cancer (SCLC) and high-grade extrapulmonary neuroendocrine carcinomas (EPNEC) share similar histopathological features and treatment, but outcomes may differ. We evaluated in our study the expression of biomarkers associated with response rate (RR) to chemotherapy and overall survival (OS) for these entities. Materials and Methods: This is a multicentre retrospective analysis of advanced EPNEC and SCLC patients treated with platinum-based chemotherapy. Paraffin-embedded tumour samples were reviewed by a single pathologist and tested for immunohistochemistry (IHC) expression of Ki-67, ERCC1, Bcl-2, and Lin28a. All images were evaluated by the same radiologist and RR was determined by RECIST 1.1. Results: From July, 2006 to July, 2014, 142 patients were identified, being 82 (57.7%) SCLC and 60 (42.3%) EPNEC. Clinical characteristics and median Ki-67 (SCLC: 60%; EPNEC: 50%; p = 0.86) were similar between the groups. RR was higher for SCLC patients (86.8% versus 44.6%; p<0.001), but median OS was similar (10.3 months in SCLC and 11.1 months in EPNEC; HR 0.69, p = 0.07). Bcl-2 expression was higher in SCLC patients (46.3% versus 28.3%, p = 0.03) and was associated with worse prognosis in EPNEC (median OS 8.0 months versus 14.7 months; HR 0.47, p = 0.02). Conclusion: EPNEC patients presented inferior RR to platinum-based chemotherapy than SCLC but tended to live longer. Neither ERCC1, Lin28, or Ki-67 were prognostic or predictive for RR in EPNEC or SCLC. High Bcl-2 expression was associated with poor prognosis in EPNEC patients.
