Seventy‐eight patients with Hodgkin's disease were treated with radiation therapy between July 1966 and July 1976 (30 Stage I, 28 Stage II, 20 Stage III). The mean follow‐up period is greater than 5 years. 90% of Stage I, 86% of Stage II, 65% of Stage III, and 82% (64/78) of all patients are NED after radiotherapy alone. Since laparotomy option (1970) 89% (50/56) of patients are NED. Fourteen patients were failures. Chemotherapy “rescued” 6 of 14. Seven have died, 1 is alive with disease, and 1 died of leukemia. Absolute survival is 90% (70/78). Failures were more frequent in patients with unfavorable histological types (9/14), and Stage III disease, primarily IIIS+ or B category (7/14). Sites of failures were mainly extranodal, primarily lung (10/14) and bone (2/14), and are consistent with hematogenous dissemination. Laparotomy performed in 41 patients identified unsuspected splenic involvement in 9 cases (22%), but was a distinct failure in confirming most “small node” positive lymphangiograms. Two patients developed acute myelocytic leukemia, both while NED 5 years posttherapy. One patient had also received adjunctive MOPP. There has been no impairment in the quality of survival that could be directly attributed to radiotherapy.
