Abstract

Five patients with Hodgkin's disease, nodular sclerosing subtype, who had multiple failures after chemotherapy and radiation therapy were treated for palliation with low-dose radiation therapy and hyperthermia to seven superficially located sites of recurrence. Six of the seven areas were in previously irradiated fields and one was at the margin of the prior radiation therapy field. Local control was obtained for all lesions and was maintained for the duration of the patients survival (5 to 27 months). Four of the five patients expired with no relapse in the area of treatment. One patient remains alive and free of recurrence in his treatment fields. Temperatures were monitored using thermistors, fluoroptic systems or thermocouples manually mapped through closed-end catheters inserted into the tumor and thermal parameters and temperature distributions were calculated. Excellent heating was obtained with 46.4% of monitored intratumoral temperatures ≥ 43°C. The average of the monitored intratumoral temperatures for all treatments (Tave) was 43.2°C; the average of the monitored intratumoral minimal temperatures for all treatments (Tmin) was 40.1°C, and the average of all monitored intratumoral maximum temperatures (Tmax) was 46.7°C. In comparison with temperatures obtained in 277 superficially located tumors of other histologies, Tmax was significantly higher in Hodgkin's disease lesions (p = 0.007). The difference in Tave approached significance (p = 0.058). These initial results support the role of radiation therapy and hyperthermia for palliation of isolated superficial recurrences in patients with Hodgkin's disease who have failed conventional therapies. In addition, this approach may aid in cytoreduction prior to bone marrow transplant in patients with superficially located bulky recurrent disease. Hyperthermia may also be considered in combination with chemotherapeutic agents for palliative treatment of recurrences.
