P-Chop: Cisplatin (P) Added To The Standard Chop Regimen As First-Line Treatment For Aggressive Non-Hodgkin Lymphoma - A Single-Institution Phase Ii Study

We designed the P-CHOP regimen, which involves the addition of cisplatin (P) to the standard CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) regimen, and investigated its activity and its toxicities in a single institution phase 11 study. Twenty-two consecutive patients with untreated, aggressive, stage I-IV non-Hodgkin lymphoma were enrolled in the study. Cisplatin was administered at a dose of 40 mg/m(2) on days I and 2, every 3 weeks: the dose and schedule of the other agents were identical to those used in the standard CHOP regimen. The complete remission (CR) rate was 86% in eligible and 80% in all the treated patients, which compares favorably with the CR rates of two recent randomized studies of CHOP versus other regimens. P-CHOP is an innovative regimen for the front-line treatment of aggressive non-Hodgkin lymphoma. It is feasible and warrants further research, which would ideally take the form of a randomized comparison of P-CHOP and CHOP, possibly with the addition of rituximab in both arms.
