RESUMO
Chemoradiotherapy for the unresectable pancreatic cancer and biliary cancer has been used for improving survival. In this study, we examined its safety and efficacy in cases with the local recurrence of pancreatic or biliary cancer after primary resection. Seven consecutive patients with recurrence of carcinoma of pancreas (n=3) and biliary system (n =4) were treated chemoradiotherapy. Local recurrence occurred around the portal vein in 6 patients and remnant pancreas in one patient respectively. Disease free survival after primary surgery was 22 months (range: 5-84). All patients received 50 Gy of conformal three-dimensional radiotherapy with concurrent 5-FU, Gemcitabine or S-1. Grade 3 of anorexia and elevation of transaminase level occurred in one patient respectively. Local tumor response was observed in two patients of pancreatic and biliary cancer respectively. Median survival calculated from the start of the chemoradiotherapy was 14.5 months (range: 6.4-23.9) in pancreatic cancer and 13.5 months (range: 10.8-19.8)in biliary cancer. Our data suggest that chemoradiotherapy is feasible and effective treatment option in patients who present local recurrence after primary surgery in pancreatic or biliary cancer.
