ABSTRACT
BACKGROUND: The pancreatic adenocarcinoma is an aggressive disease for which cure is only possible in less than 20% of the best cases. Adjuvant radiotherapy and chemotherapy so far have improved symptoms with little, but significant, increase in survival rates. METHODS: Retrospective assessment of 40 patients admitted at Department of Radiation Oncology of the Hospital Israelita Albert Einstein between April 1993 and August 1999 was done. Radical surgery with tumor resection was previously performed in 25 and palliative procedures or nothing in 15. RESULTS: Overall actuarial median survival was 14.8 months; and actuarial survival rates at 12 and 24 months were 70% and 22.2% respectively. Actuarial median survival for the group of patients with resected tumor was 21.4 and for the group of patients with non-resected tumor was 16.1 months. Expected survival rates at 12 and 24 months were 76% and 32% for the former group and 60% and 0% for the latter. CONCLUSIONS: Results were similar to other published series. Better drugs and more frequent intraoperative radiotherapy are necessary.

OBJETIVO: Avaliar retrospectivamente a sobrevida dos pacientes portadores de adenocarcinoma de pâncreas tratados no Serviço de Radioterapia do Hospital Israelita Albert Einstein, comparando os resultados com a literatura, e apresentando proposta de conduta. MÉTODOS: Entre abril de 1993 e agosto de 1999, 40 pacientes com adenocarcinoma de pâncreas foram admitidos para radioterapia neste Serviço. Destes, 25 haviam sido submetidos a procedimento cirúrgico radical com ressecçäo do tumor e em 15 o tumor näo havia sido ressecado (näo operados, biopsiados apenas ou submetidos a intervençöes cirúrgicas paliativas). RESULTADOS: A sobrevida actuarial mediana para toda amostra foi de 14,8 meses, sendo as probabilidades de sobrevida em 12 e 24 meses, 70 por cento e 22,2 por cento, respectivamente. A sobrevida actuarial mediana para o grupo de pacientes que tiveram o tumor ressecado foi de 21,4 meses e para o grupo de pacientes com tumor näo ressecado, 16,1 meses, sendo a probabilidade de sobreviver 12 e 24 meses de 76 por cento e 32 por cento no primeiro grupo e 60 por cento e 0 por cento no segundo (p=0,0156). CONCLUSÖES: Os nossos resultados säo semelhantes aos descritos na literatura médica atual. Há necessidade de introduzir novas drogas ativas para o tratamento destes tumores e a radioterapia intra-operatória tem que ser melhor explorada
