Combined 5-fluorouracil and radiation therapy as a surgical adjuvant for poor prognosis gastric carcinoma.
1984
Sixty-two patients with resectable but poor-prognosis gastric carcinoma were randomized to either no surgical adjuvant therapy or treatment with 5-fluorouracil (15 mg/kg by rapid intravenous injection X 3) plus radiation (3,750 rad in 24 fractions) initiated 3 1/2 to six weeks postoperatively. Informed consent was obtained after randomization and only from the 39 randomized to treatment. Ten patients refused their treatment assignment. The five-year survival rate for patients randomized to treatment was 23%, and for those randomized to no treatment, 4% (P less than .05). Both the survival distributions and the alive-without-recurrence distributions were significantly different for the two groups (P = .024) and favored treatment assignment. When the treatment assignment group was broken down to those patients actually receiving treatment and those refusing, five-year survival rates were: treated, 20%; treatment refusal, 30%; controls, 4%; the three survival distributions were not significantly different.
