title: Pediatric stage IV Hodgkin disease. Long-term survival.
abstract: BACKGROUND
  The optimal treatment for Stage IV Hodgkin disease (HD) remains uncertain, particularly the role of radiation therapy (RT).
  
  
  METHODS
  A retrospective review of 43 children, 18 years of age or younger, who were seen and treated for Stage IV HD between June 1970 and June 1988, was performed. All patients were treated with combination chemotherapy (CT), and 20 patients received RT after CT (combined-modality therapy, CMT). CT consisted of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) in 41 patients and both MOPP and doxorubicin (Adriamycin, Adria Laboratories, Columbus, OH), bleomycin, vinblastine, and dacarbazine in two patients. RT was added for patients who had a partial response (PR) to CT (n = 11) and/or for initial bulky thoracic disease (n = 12).
  
  
  RESULTS
  With a median follow-up of 83 months, the 7-year actuarial freedom from progression (FFP) and survival rates for all patients were 69% and 78%, respectively. For patients achieving a complete response (CR) to CT, the 7-year FFP rate was 73% and for patients with a PR it was 90% (P value not significant). The actuarial overall survival rates at 7 years were 88% for patients with CR versus 80% for patients with PR. In contrast, patients with either no response (one patient) or progressive disease (four patients) after CT had a significantly worse prognosis than patients with CR, with a 7-year actuarial survival rate of 40% (P = 0.006). FFP after CT alone was significantly more prevalent in patients with Stage IVA (11 of 13 patients) than in patients with Stage IVB disease (2 of 10 patients; P = 0.003). For these symptomatic patients, failures were almost exclusively (seven of eight patients) in sites of initial nodal disease. The addition of adjuvant RT improved the progression-free survival for patients with B symptoms: 2 of 13 patients had relapses after CMT versus 8 of 10 patients treated with CT alone (P = 0.003).
  
  
  CONCLUSIONS
  This retrospective analysis of MOPP alone compared with MOPP plus RT showed a significant difference in FFP in patients with Stage IVB HD favoring CMT.
