| Abstract: | The records of 1470 patients treated for Hodgkin's disease between 1960 and 1980 were reviewed, and sites of initial involvement were scored. Forty-four patients had disease limited to the chest after clinical and/or pathologic staging. Eighteen asymptomatic patients underwent a staging laparotomy and no occult subdiaphragmatic disease was identified. All 44 patients were treated with irradiation (XRT) to involved (IF), mantle (M), subtotal lymphoid (STLI), or total lymphoid (TLI) fields. Eighteen patients were also treated with chemotherapy, consisting of nitrogen mustard, vincristine, and procarbazine, with or without prednisone (MOP(P)), or procarbazine, melphalan, and vinblastine (PAVe). With a median follow-up of 7.5 years the survival at five and ten years was 93% and 89%, respectively, and the freedom from relapse (FFR) at five and ten years was 81% and 78%, respectively. Ten patients relapsed, all in supradiaphragmatic sites (including six relapses within lung parenchyma). Eight had initially received XRT alone, and two had received combined modality treatment. The risk of relapse in the 26 patients treated with XRT alone varied inversely with the volume irradiated: IF, 100% (3/3); M, 45% (3/7); STLI, 17% (2/12); TLI, 0% (0/4) relapsed. Seven of the eight relapsing patients treated with XRT alone were salvaged with subsequent XRT and/or chemotherapy whereas both of the combined modality patients who relapsed, died with progressive disease despite all salvage therapy. |
