title: Is combined modality therapy necessary for advanced Hodgkin's disease?
abstract: OBJECTIVE
  To determine whether single-modality therapy is optimal management for patients with Stage III-IV Hodgkin's disease.
  
  
  METHODS
  All patients with advanced (Stage III and IV) Hodgkin's disease treated at the University of Florida from 1964 through 1989 (n = 141) were studied retrospectively for factors predictive of good outcome with single-modality therapy. Treatment modalities varied and were distributed as follows: combined-modality therapy (CMT), 55 patients; chemotherapy alone (CX), 50 patients; and radiotherapy alone (RT), 36 patients.
  
  
  RESULTS
  Ten-year rates of freedom from relapse and overall survival for all Stage III patients were 66% and 59% compared with 36% and 35% for Stage IV patients. The RT subset was highly selected with the majority of patients having nonbulky Stage IIIA disease. Within the RT group, multivariate analysis identified the degree of splenic involvement and age as the factors most associated with freedom from relapse. In patients treated with CX, multivariate analysis identified bulky tumor (maximum transverse tumor dimension > 6 cm) as the most important prognostic factor for relapse. In patients without bulky disease (< or = 6 cm), the probabilities of freedom from relapse and overall survival at 10 years, respectively, according to treatment group were 53% and 58% for RT patients, 60% and 56% for CX patients, and 83% and 71% for CMT patients. For patients without bulky disease, the probability of freedom from relapse was significantly better for the CMT group than for CX patients (p = 0.03) or RT patients (p = 0.04), but there was no statistical difference in overall survival among the three groups. In patients with bulky disease (> 6 cm), the probabilities of freedom from relapse and overall survival at 10 years were 44% and 45% for RT patients, 9% and 0% for CX patients, and 72% and 58% for CMT patients. Freedom from relapse and overall survival were significantly better (p = 0.0001) for CMT patients compared with CX patients. Fatal hematopoietic disorders developed in 10 patients: 2 of 36 RT patients, 2 of 50 CX patients, and 6 of 55 CMT patients. Nine patients had received chemotherapy, and eight had six or more cycles of alkylator-based chemotherapy.
  
  
  CONCLUSIONS
  This retrospective study suggests that combined-modality therapy is preferable to single-modality therapy in the majority of patients with advanced Hodgkin's disease.
