Pancreatic cancer. Adjuvant combined radiation and chemotherapy following curative resection.

The efficacy of combined radiation and fluorouracil as adjuvant therapy for pancreatic cancer is suggested by a prospective randomized study conducted by the Gastrointestinal Tumor Study Group (GITSG). Twenty-two patients randomized to no adjuvant treatment and 21 to combined therapy were analyzed. Neither life-threatening toxic reaction nor death due to toxic effect was encountered. The study was terminated prematurely because of an unacceptably low rate of accrual combined with the observation of increasingly large survival differences between the study arms. Median survival for the treatment group (20 months) was significantly longer than that observed for the control group (11 months). Four patients, three in the treated and one in the control group, have survived five years or longer following surgery. The extent of the tumor and initial performance status were significantly and independently related to survival.
