Hodgkin's disease in the elderly: Improved treatment outcome with a doxorubicin-containing regimen

Purpose: Hodgkin's disease (HD) is a malignancy that displays a bimodal age distribution. Previous reports of treatment in patients ≥ 60 years have found a poor outcome, particularly in patients with advanced disease. Because of an improved side-effect profile, the regimen of chlorambucil, vinblastine, procarbazine, and prednisone (ChlVPP) has been proposed for use in elderly patients. Patients and Methods: From September 1982 to May 1998, 262 patients with previously untreated HD received either ChlVPP (n = 176) or ChlVPP plus doxorubicin/bleomycin/vincristine (ChlVPP/ABV hybrid; n = 86). Fifty-six patients were ≥ 60 years old, and 206 were younger than 60 years. Results: The 5-year overall survival (OS; 87% v39%) and the 5-year event-free survival (EFS; 75% v 31%) favored patients younger than 60 years of age. Prognostic factors analyzed in patients ≥ 60 years of age, other than type of therapy, included sex, stage, Karnofsky performance score, lactic dehydrogenase, number of extranodal sites, B symptoms, size of largest mass, and histologic subtype. In patients older than 60 years, none of the clinical features was a statistically significant predictor of EFS; however, ChlVPP/ABV hybrid was associated with a decreased risk of an event (relative risk, 0.40; 95% confidence interval, 0.19 to 0.83; P = .014) compared with ChlVPP. The 5-year OS for patients ≥ 60 years who received ChlVPP was 30%, compared with 67% for those patients receiving the ChlVPP/ABV regimen (P = .0086) Conclusion: Patients ≥ 60 years with HD who require chemotherapy are better treated with ChlVPP/ABV hybrid than with ChlVPP alone.
