INFRADIAPHRAGMATIC HODGKINS-DISEASE - LONG-TERM RESULTS OF COMBINED-MODALITY THERAPY

Hodgkin's disease (HD) confined below the diaphragm accounts for less than 5% of all patients with HD. Although the major characteristics of this presentation appear established, optimal modalities of treatment still remain difficult to define. From April 1972 to October 1988, 28 patients with newly diagnosed infra-diaphragmatic HD, clinical stages I or II have been treated with 3 successive prospective protocols com bining initial chemotherapy and radiotherapy (40 gy). This series of p atients accounted for 4,3% of patients with HD limited to clinical sta ges (CS) I and II. Overall survival and freedom from relapse at 15 yea rs were 74,4% and 73% respectively, without significant differences be tween clinical stages I and II, presence or absence of B symptoms or h istologic subtype. There is only a trend (p < 0,10) in favour of patie nts younger than 40 years. In all 7 clinically staged IA patients no r elapses were seen and combined treatment does not appear to be better than inverted Y irradiation alone. On the other hand initial chemother apy seems necessary in patients with CS II A and B since 15 of our 21 patients are alive in first CR whereas the crude rate of transdiaphrag matic nodal relapses may reach up to 53% following radiotherapy alone.
