AbstractOut of 516 patients who entered in the two successive EORTC trials H2 and H5 for supra-diaphragmatic stages I and II Hodgkin's disease (HD), and who received an infra-diaphragmatic irradiation, 36 (7%) developed late radiation injuries of the gastrointestinal tract (GIT). Twenty-five patients presented with ulcers (stomach or duodenum), 2 with severe gastritis, 6 with small bowel obstruction or perforation and 3 patients had both an ulcer and bowel obstruction. A previous laparotomy played an important role. While the complication rate was 2.7% without any previous abdominal surgery, it was 11.5% after laparotomy (p less than 0.001). Fractionation was also found to be of importance in the occurrence of complications: three different weekly schedules were used -5 x 2 Gy, 4 x 2.5 Gy and 3 x 3.3 Gy; the GIT complication rates were 4, 9 and 22%, respectively (p less than 0.001). When combining laparotomy and fractionation, we found that the patients who were treated using 5 weekly fractions of 2 Gy without any prior laparotomy had a very low rate of late digestive complications (1%), whereas the patients who received 3 weekly fractions of 3.3 Gy after laparotomy presented a 39% complication rate. The other subgroups of patients were at an intermediate risk (from 5 to 13%) of late digestive injuries. Since most patients received 40 Gy with only very small variations, the influence of the radiation dose could not be investigated.(ABSTRACT TRUNCATED AT 250 WORDS)
