Abstract Between Jan 1, 1968, and Dec 31, 1980, 108 previously untreated patients with Hodgkin's disease pathologic stages (PSs) IA (29 patients) and IIA (79 patients) initially received radiotherapy alone. One postoperative death (due to pulmonary embolus) (0.9\%) occurred, with one serious complication (0.9\%). Between 1968 and 1973, patients were randomized to receive either involved field radiation treatment (RTIF) or extended field radiation treatment (RTEF). Since 1973 all patients have received RTEF, 4,000 cGy in four to five weeks, with a median follow-up of 7.4 years. Complete remission (CR) was achieved in 102 patients (94.4\%), with no significant difference according to treatment or stage. Of the complete responders, 25 patients relapsed: 5/15 RTIF and 20/87 RTEF (P = .6). Twenty-one of 25 relapsing patients achieved a second CR. Disease free survival rates at five and ten years constituted: PS IA, 78.6\% for both; PS IIA, 74.8\% and 73.1\% (P = .6); RTEF, 76.7\% for both; RTIF, 73.3\% and 66.7\% (P = .7). Eighteen patients have died: eight of recurrent lymphoma, two of pulmonary embolus, one each of myocardial infarction, pulmonary fibrosis, and acute nonlymphocytic leukemia (ANLL) (following salvage chemotherapy), and one of diffuse histiocytic lymphoma (DHL). Four patients died in remission of unrelated causes. Actuarial survival rates at five and ten years constituted: PS IA, 95.7\% and 72.4\%; PS IIA, 89.6\% and 81.4\% (P = .3); RTIF, 93.7\% for both; RTEF, 90.7\% and 71.2\% (P = .2). Age, sex, number of sites, and mediastinal involvement did not influence the outcome. Acute toxicity was modest and more frequent among those receiving RTEF (P = .08). Chronic toxicity (onset more than 30 days after completion of treatment) was identified in 16 patients: 1/16 RTIF; 15/92 RTEF (P = .5). Three patients developed a second malignancy: one carcinoma of the cervix in situ; one ANLL (following salvage chemotherapy); and one DHL of the stomach. At least 75\% of patients with PS IA and IIA Hodgkin's disease were cured by radiation alone, with a risk of secondary malignancy following radiation alone of 0.9\%. Since the majority of relapsing patients were successfully salvaged by chemotherapy, radiation alone appears to be the initial treatment of choice in this group of patients.
