Stage I to IIB Hodgkin's disease: the combined experience at Stanford University and the Joint Center for Radiation Therapy.

The treatment records of 180 patients with pathological stage (PS) IB to IIB Hodgkin's disease treated at Stanford University Medical Center (SUMC) or the Joint Center for Radiation Therapy (JCRT) were reviewed. Pretreatment characteristics were analyzed to assess their influence on survival and freedom from relapse (FFR). The two most important disease characteristics predictive of relapse were the number and type of B symptoms present and the mediastinal mass ratio (MMR). Patients with both fevers and weight loss had a 7-year survival and FFR of only 57% and 48%, respectively. The poor prognosis in this group was apparent for treatment with either radiation (XRT) alone or combined modality therapy (CMT). Patients with night sweats only had no adverse effect of B symptoms on outcome. Patients with a MMR greater than 1/3 had a 7-year FFR of only 58% after XRT, but 79% after CMT (P = .12). The 7-year survivals for these patients were 85% and 88%, respectively. CMT improved the FFR of the entire group of 180 patients when compared with XRT (7-year FFR 86% and 74%, respectively, P = .02); however, survival in the two treatment groups was similar (88% and 89%). Among patients treated with radiation alone, there was a similar survival and FFR irrespective of whether pelvic irradiation was included in the initial treatment fields.
