Purpose
To compare the efficacy and safety of a biweekly CHOP regimen consisting of cyclophosphamide (CPA), doxorubicin (DOX), vincristine (VCR), and prednisolone (PSL) and those of a biweekly THP-COP regimen containing pirarubicin (THP), an anthracyclin with less cardiotoxicity than DOX.
Methods
A prospective, randomized phase II study with 80 patients (40 receiving CHOP or THP-COP) less than 70 years of age with previously untreated aggressive non-Hodgkin’s lymphoma (NHL). The regimens consisted of DOX or THP 50 mg/m2, CPA 750 mg/m2, VCR 1.4 mg/m2, and PSL 100 mg/body administered for 5 days every 2 weeks for eight cycles.
Results
No significant differences in known prognostic factors were found between the two groups. Complete remission rate was 72.5% (72.5% for CHOP, 72.5% for THP-COP). The 5-year overall survival rate was 49.2% (43.7% for CHOP, 54.0% for THP-COP). When the patients were divided into groups with favorable or poor prognostic factors according to the International Prognostic Index, survival of the former group (L/LI) was superior to that of the later group (HI/H), regardless of chemotherapy regimen (P<0.001). Although grade 3 cardiotoxicity occurred in one patient in the CHOP group, no fatal toxic reactions occurred in either group. The THP-COP produced results equivalent to those of CHOP regarding efficacy and safety in aggressive NHL patients less than 70 years of age.
Conclusions
Although both regimens effectively treated those patients with favorable prognostic factors, neither was satisfactory for treating those with poor prognostic factors.
