[Long-term results of radiotherapy of pancreatic cancer].
Long-term results of radiotherapy of 131 pancreatic cancer patients were discussed. The mean survival time after the therapy was 15.6 mos., in patients with histologically verified diagnosis of cancer--15 mos. During 1 year 64.4% of the patients survived, 2 years--44.7%, 3 years--35.2%, 4 years--9.6%, 5 years--3.2%. The results obtained were 2.5-fold better than those after biliodigestive anastomoses and 3-fold better than those after chemotherapy. Irradiation within a short period (0.5-1 month) after palliative or exploratory operation (the mean survival time was 20.9 mos.) seemed one of the most realistic methods for improving therapeutic results in pancreatic cancer. The mean survival after placing cholecystojejunoanastomosis and radiotherapy was 17.7 mos. (from the onset of irradiation), after exploratory laparotomy and irradiation--18.9 mos., after palliative tumor resection and irradiation--23.9 mos. The efficacy of radiotherapy was lowered with increasing an interval between explorative or palliative operation and irradiation. A split course of gamma-beam therapy was recommended depending on a patient's general status (10-20 after Karnovsky).
