title: Erythrocyte mean corpuscular volume during cytotoxic therapy and the risk of secondary leukemia.
abstract: Erythrocyte mean corpuscular volume (MCV) evolution during cytotoxic therapy of Hodgkin's disease, lymphoma, multiple myeloma, ovarian cancer, and breast cancer was studied. The fastest and the highest MCV increases were observed in the diseases and with the therapies the most frequently involved in secondary leukemia: Hodgkin's disease treated with MOPP (mechlorethamine, vincristine, procarbazine, prednisone), and multiple myeloma and ovarian cancer treated with melphalan. On the contrary, with cytotoxic regimens not linked to a high frequency of secondary leukemia such as CMF (cyclophosphamide, methotrexate, 5-fluorouracil) used in ovarian or breast cancer, MCV increase was moderate. As the MCV increase reflects the bone marrow reaction to cytotoxic therapy, an unusually high increase could indicate bone marrow damages which could lead to secondary leukemia.
