Abstract
Nine male patients with disseminated Hodgkin's disease who had relapsed and/or were refractory to two or more non‐“cross‐resistant” programs of combination chemotherapy (range, two to five previous programs; median, three) were admitted into a study of treatment with wide‐field low‐dose radiation therapy (2,000 cGy), to all lymph node bearing areas, the liver, the spleen, and in selected cases the lungs (1,000 cGy). Simultaneous with each course of radiation therapy, chemotherapy with BCNU and procarbazine given at 50% doses of a known program of chemotherapy (BOPP) with vincristine and prednisone was given. Treatment was completed in five patients. Three of these achieved a complete remission; the other two had a partial response. Of the other four, two died during treatment with interstitial pneumonitis (probably radiation induced), and two failed to respond. Remission durations were 18+, 38, and 44+ months. Pulmonary toxicity was severe; however, hematologic and other toxicities were acceptable. The incorporation of wide‐field low‐dose radiation should be considered in programs of rescue for patients with Hodgkin's disease who relapse or are refractory to standard combination chemotherapy.
