Abstract
When uncomplicated neutropenia during doxorubicin (Adriamycin), bleomycin, vinblastine and dacarbazine (ABVD) chemoterapy for the treatment of Hodgkin's lymphoma is encountered, it is unclear whether or not treatment should be modified. In the present study, we determined the incidence of neutropenia, febrile neutropenia, and the relationship of febrile neutropenia to grade III/IV neutropenia and dose modification, in a large university patient population. We reviewed the charts of patients diagnosed with Hodgkin's lymphoma between 1 January 1990 and 31 December 2002 who were treated with ABVD chemotherapy, and seen at the University of Iowa with complete diagnosis, staging, and treatment dosing records. Adequate data was available on 894 treatments in 81 patients with Hodgkin's lymphoma treated with ABVD chemotherapy. Grade III/IV neutropenia was present on the scheduled day of treatment in 187 (20.9%) treatments in 64 (79%) patients. Grade III/IV neutropenia was most common at cycle 1 day 15. Febrile neutropenia developed nine times in eight patients, and eight episodes of febrile neutropenia developed when the treatment-day absolute neutrophil count (ANC) ⩾1000. Dose delay of >4 days and/or dose reduction to <80% of original doxorubicin dose following grade III/IV neutropenia occurred in 29 of 187 treatments, with no episodes of febrile neutropenia. With grade III/IV neutropenia on the day of therapy, 158 treatments were administered without dose reduction or dose delay with one subsequent episode of febrile neutropenia. Neutropenia during ABVD is common, and dose modification for uncomplicated neutropenia on the day of treatment may not reduce the risk of febrile neutropenia. It may be possible to maintain dose intensity in the face of uncomplicated neutropenia during ABVD therapy.
