The contribution of clinical trials to the treatment of patients with early stages of Hodgkin's disease.
An analysis of the results that have been obtained in several recent controlled clinical trials showed that the inclusion of combination chemotherapy in the initial treatment of Hodgkin's disease significantly improved relapse-free survival but did not improve survival. This is due to the high efficacy of salvage chemotherapy. Paradoxically, the advent of powerful combination chemotherapy makes initial treatment by radiotherapy alone possible in a large proportion of patients with early stages of Hodgkin's disease. Prognostic factors have been identified by a multivariate analysis of the results obtained in the three controlled clinical trials carried out by the EORTC. These factors can help to delineate the subsets of patients who can be treated initially by radiotherapy alone with an acceptable relapse rate and to adjust the size of the radiation fields. The two prominent prognostic factors are: a combination of systemic symptoms and erythrocyte sedimentation rate the number of lymphatic areas involved.
