Abstract
Ninety-one laparotomy-staged (LAP) IA and IIA Hodgkin's disease (HD) patients were analyzed to evaluate the prognostic significance of stage, mediastinal status, extranodal disease and histology. Forty IA patients were treated with radiotherapy (XRT) only; of 51 IIA patients, 44 received XRT only and 7 had additional chemotherapy. Disease-free survival (DFS) at 5 and 10 years was 81% and 70%, respectively, with overall survival (S) of 93% and 86%, respectively. Disease-free survival for IA patients (93% at 5 and 10 years) was significantly superior to IIA (73% at 5 years, 52% at 10 years). Survival differences were not statistically significant. For IIA patients receiving XRT only, large mediastinal disease was an adverse factor for DFS. Small mediastinal disease in IIA was significantly better than no mediastinal disease. For the whole group of LAP IA and IIA treated by XRT only, three prognostic groups were identified: (1) Stage IA and Stage IIA with mediastinal disease, but 10 cm) mediastinal adenopathy.
