Experience with Sorafenib in 3 Hospitals in Sao Paulo.

INTRODUCTION AND AIM: Sorafenib has been the standard of care for first-line treatment of advanced hepatocellular carcinoma, a complex disease that affects an extremely heterogenous population. Thereby requiring multidisciplinary individualized treatment strategies that match the disease characteristics and the patients' specific needs. MATERIAL AND METHODS: Data for 175 patients who received sorafenib for hepatocellular carcinoma in three different hospitals in Sao Paulo, Brazil over a span of nine years were retrospectively analyzed. RESULTS: The median age was 62 years. Percentages of patients with Child-Pugh A, B and C liver cirrhosis were 61%, 31% and 5%, respectively. Approximately half of the patients had Barcelona Clinic Liver Cancer stage B disease, and the other half had stage C. The median treatment duration was 253 days. Sorafenib dose was reduced to 400 mg/day in 41% of the patients due to toxicity. Overall objective response rate as per Response Evaluation Criteria in Solid Tumors and its modified version was 39%. Patients who received transarterial chemoembolization (TACE) at any point during sorafenib therapy were significantly more likely to experience an objective response. After a median follow-up of 339 days, the median overall survival was 380 days. Child-Pugh cirrhosis, tumor response and concomitant chemoembolization were independent prognostic factors for overall survival in multivariate analysis. CONCLUSION: Our results suggest that, in experienced hands, sorafenib therapy may benefit carefully selected hepatocellular carcinoma patients for whom other therapies are initially contraindicated, including those patients with Child-Pugh B liver function and those patients who are subsequently treated with concomitant TACE.

Advanced hepatocellular carcinoma. Review of targeted molecular drugs.

Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world in terms of incidence, accounting for approximately 630 thousand new cases per year; in addition, HCC is the third most common cause of cancer death. Worldwide, the greatest risk factors for HCC are the infections caused by hepatitis B and C viruses, which increase the risk of developing the disease by about 20 times. The standard treatment in the early stages of the disease, such as surgical resection, local ablation and liver transplantation, are able to cure a proportion of patients, but most cases of HCC present in advanced stages, precluding the use of such treatments with curative intent. In these advanced stages, systemic treatments are commonly used. Unfortunately, chemotherapy with conventional cytotoxic agents is ineffective and does not seem to modify the natural history of disease. Treatment options for patients with advanced HCC are extremely limited, but the identification of signaling pathways, and the recognition of the role of these pathways in the pathogenesis of the disease resulted in the development of drugs directed at specific therapeutic targets. One such drug is Sorafenib, a kinase inhibitor with antiangiogenic and antiproliferative properties. In conclusion, Sorafenib has demonstrated survival benefits in patients with advanced HCC, thus representing a new standard reference for systemic treatment in these cases.

Evaluation of quality of life in patients with metastatic colorectal cancer treated with capecitabine.

PURPOSE: This study evaluated the effects of oral capecitabine on the quality of life (QOL) of Brazilian patients with metastatic colorectal cancer who received capecitabine (1000 or 1250 mg/m2 twice a day on days 1-14, every 3 weeks) in a prospective, multicenter, open-label, noncomparative study. PATIENTS AND METHODS: Patients completed the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires before cycle 1, at weeks 7 and 13, and at the end of treatment. In total, 1437 patients (mean age, 59.6 years [+/- 13.5 years]) were enrolled. RESULTS: In women, statistically significant improvements were observed in 6 QLQ-C30 and 6 QLQ-CR38 domains (QLQ-C30: emotional function, nausea/ vomiting, pain, constipation, financial problems, and body image; QLQ-CR38: future perspective, micturition problems, defecation problems, stoma-related problems, weight loss and global health status). In men, statistically significant improvements were observed in 8 QLQ-C30 and 5 QLQ-CR38 domains (QLQ-C30: emotional function, social function, pain, insomnia, appetite loss, constipation, financial problems, and future perspective; QLQ-CR38: micturition problems, defecation problems, stoma-related problems, weight loss, and global health status). Statistically significant worsening of sexual function/enjoyment occurred in both sexes. CONCLUSION: Overall, 59%-86% of patients maintained or improved QOL during capecitabine therapy.

Resposta terapêutica ao ABVD em pacientes com doença de Hodgkin resistentes ao MOPP / Therapeutic response to ABVD in patients with Hodgkin's disease resistant to MOPP

Apresentam-se os resultados obtidos em 16 pacientes com doenças de Hodgkin avançada (DHA) e resistentes ao MOPP (mostarda nitrogenada, vincristina, procarbazida e prednisona) e que foram tratados com o esquema ABVD (adriamicina, bleomicina, vinblastina e dacarbazina) no Serviço de Clínica Médica do Hospital A. C. Camargo, Säo Paulo. O ABVD induziu remissöes completas (RC) em 7 pacientes (43,7%) e remissöes parciais (RP) em 4 pacientes (25%). Nos pacientes que entraram em RC após 6 ciclos de ABVD näo foi realizado nenhum tratamento de manutençäo. Os pacientes que entraram em remissäo completa tiveram sobrevida média, em 72 meses, de 57,1% e sobrevida livre de doença, no mesmo período, de 37,5%. Estes resultados indicam que näo há resistência cruzada entre MOPP e ABVD e que este último parece ser um esquema efetivo e tolerável para os pacientes portadores de DHA e resistentes ao MOPP, embora nossos resultados tenham sido inferiores ao estudo original de Santoro e Bonadonna
