Gastro-duodenal morbidity of para-aortic and iliac lymph node irradiation using a single anterior 16 MV X-ray field.
Eighty-one patients with testicular tumours received para-aortic and iliac lymph node irradiation using 16 MV X-rays through a single anterior field. Eleven of 62 patients with seminoma (18%) and 11 of 19 with teratoma (58%) developed dose-related gastro-duodenal complications. There were no long-term sequelae. The average follow-up is 4.3 years (range 9 months to 8 years). With this method of treatment the structures anterior to the nodes receive a higher dose than the nodes themselves, and it is not suitable when the patient's antero-posterior separation necessitates an applied dose greater than 4000 cGy in 20 daily fractions over 28 days (1351 RET).
