title: A randomized EPOCH vs. CHOP front-line therapy for aggressive non-Hodgkin's lymphoma patients: long-term results.
abstract: BACKGROUND
  The value of continuous-infusion chemotherapy (EPOCH) vs. the standard CHOP combination was evaluated in 78 patients with previously untreated aggressive non-Hodgkin's lymphoma in a randomized phase III clinical trial.
  
  
  METHODS
  The EPOCH regimen given to 38 patients consisted of the drugs etoposide (50 mg/m2), vincristine (0.4 mg/m2), and doxorubicin (10 mg/m2), all given in a continuous infusion on days 1-4. Cyclophosphamide (750 mg/m2) was administered on day 6 as i.v. bolus, while prednisone was given orally 60 mg/m2 on days 1-6. Courses were repeated every three weeks. CHOP was given to 40 patients as routinely prescribed.
  
  
  RESULTS
  Forty-eight patients were males and thirty were females. Their ages ranged from 19-75 years (median 45 years). Forty-three (55%) had grade 2 and thirty-five (45%) had grade 3 pathologic subtype. Nine patients (12%) presented with stage I, fourteen (18%) with stage II, forty (51%) with stage III, and fifteen (19%) with stage IV disease. The different clinico-pathologic characteristics, including international index categories, were comparable in the two groups. The number of courses given ranged between 3 and 9 (median 6) for both the EPOCH and CHOP regimens. Complete remission (CR) was achieved in 19 (50%), and 27 (67%) of the 38 and 40 patients for both the EPOCH and CHOP combinations, respectively. After a median observation time of 27 months, the four-year overall and failure-free survival rates were 42% and 30% for the EPOCH and 71% and 54% for the CHOP regimen (P = 0.006 and 0.1 for the overall and FFS rates, respectively). Toxicities were comparable and were mostly of grades 1 and 2, except for hair loss, hematologic toxicities, and infectious episodes which were more common in the EPOCH group. In the EPOCH group, overall survival rates were 55% vs. 22% (P < 0.04) at four years for the low-risk (2 prognostic factors) and high-risk (> 2 factors) groups, respectively.
  
  
  CONCLUSIONS
  Thus, it may be concluded that continuous-infusion (EPOCH) chemotherapy did not improve treatment outcome over that of the CHOP regimen for aggressive non-Hodgkin's lymphoma patients.
