[Prognostic factors during control of the course of lymphogranulomatosis: comparison of 2 therapy technics and analysis of serologic parameters].

Abstract

Between 1970 and 1980, 339 patients with Hodgkin's disease in stages IA to IIIB were treated at the Department of Radiotherapy, University of Essen, FRG. 65 patients (group A) were irradiated using a multiple-field-technique with cobalt-60, 110 patients (group B) with mantle fields, inverted Y or paraaortic extended fields given with 5.7 MeV photons. There were no significant differences between the cumulative survival times, local and marginal recurrences. However, the recurrence rates of unirradiated lymph node regions were different, mainly due to absent or given paraaortic treatment. The presence of initially normal blood parameters (BSR, relatively lymphocyte count, haptoglobin, copper, iron) is of high prognostic value. Combined, they allow a correct prognosis as to the five year recurrence rate in up to 98% of cases. The prognostic precision of initially pathologic values was considerably reduced, even if a normalization had occurred after one year from the initiation of treatment.
