title: A randomized study in stage IIIB and IV Hodgkin's disease comparing eight courses of MOPP versus an alteration of MOPP with ABVD: a European Organization for Research and Treatment of Cancer Lymphoma Cooperative Group and Groupe Pierre-et-Marie-Curie controlled clinical trial.
abstract: OBJECTIVE
  We report a prospective randomized study comparing the relative efficacy of alternating chemotherapy mechlorethamine, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (MOPP/ABVD) with the standard MOPP chemotherapy in patients with stage IIIB and IV Hodgkin's disease (HD). The purpose is to study the influence of time of remission on clinical outcome.
  
  
  METHODS
  After two courses of MOPP, patients were randomized to receive six further courses of MOPP, or two courses of ABVD followed by two courses of MOPP and two courses of ABVD. Radiotherapy was given to areas presenting with masses > or = 5 cm and to residual masses after course no. 4. Evaluation of response (complete remission [CR]) took place after two courses (CR2), after four courses (CR4), at the end of chemotherapy (CR8), and after additional radiotherapy (CR(CT + RT)). Logistic regression analysis was used to study prognostic factors for response at the end of chemotherapy. Cox analysis was used to study prognostic factors for survival. Two hundred seven patients were registered, 192 (93%) of whom were randomized.
  
  
  RESULTS
  The CR rate at the end of chemotherapy (CR8) was similar in both arms (57% v 59%). However, there were more progressions in the MOPP arm compared with the MOPP/ABVD arm (23% v 8%, P = .014). A significantly higher failure-free survival (FFS) rate was found in the MOPP/ABVD arm (60% v 43% at 6 years, P = .025). There was no difference in the relapse-free survival (RFS) or survival rate. Of patients not in CR4, only 28% still reached a CR8. RFS at 6 years of patients with CR4 (69%) was not different from that of patients with CR8 (68%); patients with a CR(CT + RT)) had a lower RFS rate (48%). CR4 (P < .001) predicted strongly for final remission at the end of chemotherapy. Cox analysis showed that age more than 50 years, six or more involved lymph node areas, no CR by the fourth cycle, chemotherapy with MOPP alone, and no radiotherapy were unfavorable factors for survival.
  
  
  CONCLUSIONS
  MOPP/ABVD chemotherapy significantly improved response and FFS rates, but had no influence on RFS and survival rates. Early CR (CR4) is an important factor for final remission and might be used to select a group of patients with a good prognosis.
