Procarbazine-Free OEPA-COPDAC Chemotherapy in Boys and Standard OPPA-COPP in Girls Have Comparable Effectiveness in Pediatric Hodgkin's Lymphoma: The GPOH-HD-2002 Study

Purpose Vincristine, etoposide, prednisone, and doxorubicin (OEPA)–cyclophosphamide, vincristine, prednisone, and dacarbazine (COPDAC) is derived from standard vincristine, procarbazine, prednisone, and doxorubicin (OPPA)–cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) chemotherapy by replacing procarbazine with etoposide and dacarbazine for a potentially less gonadotoxic regimen for boys with Hodgkin's lymphoma (HL). Patients and Methods Five hundred seventy-three pediatric patients with classical HL were enrolled onto the German Society of Pediatric Oncology and Hematology–Hodgkin's Disease (GPOH-HD) -2002 study between November 2002 and December 2005. Boys received two courses of OEPA and girls received two courses of OPPA for induction. Treatment group (TG) -2 (intermediate stages) and TG-3 (advanced stages) patients received further two or four cycles COPP (girls) or COPDAC (boys), respectively. After chemotherapy all patients received involved-field irradiation with 19.8 Gy, excep...
