An evaluation of total nodal irradiation as treatment for stage III a Hodgkin's disease

Abstract

Between April 1969 and December 1974, 37 patients with surgically staged III A Hodgkin's disease were treated with total nodal irradiation (TNI). Their probability of relapse-free survival at 7 years is 51% and overall survival 82% with the majority of patients remaining disease free after retreatment with MOPP (10 of 16). In contrast, 21 stage III B patients treated with TNI and MOPP chemotherapy over the same time period have a relapse-free survival of 74% and overall survival of 91%. Because of superior results in treating stage III B patients with combined modality treatment, we fell that a relapse-free survival of 51% may not justify continuation of TNI as the only modality of treatment for patients with stage III A disease, and we have initiated a trial of combined radiation therapy and MOPP chemotherapy in these patients. The most effective treatment of stage III A Hodgkin's disease, however, remains uncertain and depends both on the ultimate risk of combined modality treatment and the success of retreatment following relapse after radiation.
