Treatment of Localized and Locally Advanced, High-Risk Prostate Cancer: A Report From the First Prostate Cancer Consensus Conference for Developing Countries.

PURPOSE: To generate and present survey results on important issues relevant to treatment and follow-up of localized and locally advanced, high-risk prostate cancer (PCa) focusing on developing countries. METHODS: A panel of 99 PCa experts developed more than 300 survey questions of which 67 questions concern the main areas of interest of this article: treatment and follow-up of localized and locally advanced, high-risk PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up of localized and locally advanced, high-risk PCa in areas of limited resources discussed in this article. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion and not on a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations considered cost-effectiveness as well as the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. Results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this article can guide physicians managing localized and locally advanced, high-risk PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment of localized and locally advanced, high-risk PCa in developing countries have not been defined, this article will serve as a point of reference when confronted with this disease.

Impacto da adição da temozolamida à radioterapia no tratamento de crianças portadoras de tumor de tronco cerebral / Impact of the addition of temozolomide to radiotherapy in the treatment of children with brain stem tumors

OBJETIVO: Analisar o impacto da adição da temozolamida à radioterapia em tumores de tronco cerebral em crianças. MATERIAL E MÉTODO: Entre 2000 e 2005 foram analisadas, retrospectivamente, 64 crianças com tumor do tronco cerebral. Dessas crianças, 32 receberam temozolamida(grupo 1) e 32 não a receberam (grupo 2). RESULTADOS: A idade mediana no grupo 1 foi de 8,2 anos e no grupo 2 foi de 7,5 anos. A localização tumoral era predominantemente difusa (53%) emambos os grupos. Todos os pacientes receberam radioterapia com doses superiores a 50 Gy. No grupo1 foram ministrados nove ciclos, em média, de quimioterapia (3û14 ciclos). O tempo de progressão de doença foi de 7,9 meses no grupo 2 versus 13,8 meses no grupo 1. A sobrevida global foi de 8,8 meses (0,3û30,9 meses) no grupo 1 e de 14,6 meses (4,3û33 meses) no grupo 2. CONCLUSÃO: A utilização da temozolamida após a radioterapia proporcionou aumento da sobrevida, deseis meses em média, nos pacientes pediátricos com tumor do tronco cerebral.

OBJECTIVE: To analyze the impact of adding temozolomide to radiotherapyin pediatric brain stem tumors. MATERIAL AND METHOD: Between 2000 and 2005, 64 children with brain stem tumor were analyzed: 32 received temozolomide (group 1) and 32 did not(group 2). RESULTS: The median age of patients in group 1 was 8.2 year-old and in group 2 was 7.5 year-old. The predominant tumoral localization was diffuse (53%) in both groups. All of the patients were submitted to radiotherapy. In group 1, the median number of temozolomide cycles was 9 (3û14 cycles). Time of disease progression was 7.9 months in group 2 versus 13.8 months in group 1. Overall survival was 8.8 months (0.3û30.9 months) in group 1 and 14.6 months (4.3û33 months) in group 2. CONCLUSION: In our institution,adding temozolomide to radiotherapy increased the overall survival in approximately six months in brain stem pediatric tumors.
