[Autologous bone marrow transplantation following high-dose busulfan and etoposide for a patient with non-Hodgkin's lymphoma].

A 26-year-old man was admitted to our hospital with cervical tumor and facial edema on July 8, 1991. Examination of chest X-ray and chest CT showed a bulky tumor in the mediastinum and pleural effusion. A pathological diagnosis of non-Hodgkin's lymphoma (diffuse large cell, immunoblastic type) was made by biopsy of the cervical lymph node. MACOP-B chemotherapy or other combination chemotherapy did not achieve complete remission. The man was given a preparative regimen consisting of busulfan at 16 mg/kg orally and 60 mg/kg of etoposide (Bu-Et); 30 mg/kg of etoposide was administered by continuous intravenous infusion for 12 hours on day-5 and day-4, before he received autologous bone marrow on February 20. He was then given 300 micrograms of G-CSF was given to him to accelerate recovery of hematopoiesis from one day after BMT. The neutrophil count to 500/microliters recovered on day 28, and residual tumors disappeared. Although moderate-grade stomatitis and nasal bleeding developed, these toxicities were controllable and no veno-occlusive disease resulted. Regimen-related toxicities of Bu-Et preparatory regimen have been generally considered to be severe, but continuous and separate administration of etoposide as reported in this case may be useful to reduce side effects of this preparatory regimen.
