title: Autologous bone marrow transplantation in the therapy of small cell carcinoma of the lung.
abstract: Ten patients with small cell carcinoma of the lung were entered into a chemotherapeutic treatment program consisting of cyclophosphamide, vincristine, Adriamycin, and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea. Two courses of combination chemotherapy were administered to each patient followed by a third course with the same doses of drugs used on Course 2 but with autologous bone marrow transplantation given 24 to 48 hr after drug infusion. No differences could be detected between Courses 2 and 3 in terms of the magnitude, timing, or degree of myelosuppression. Serial bone marrow biopsies documented a progressive decline in granulocyte-macrophage colony-forming units in culture per mg bone marrow medullary core from 138 +/- 179 (S.D.) prior to chemotherapy to 7 +/- 11 after the marrow transplant recovery (p = 0.05). These data suggest that autologous bone marrow transplantation does not reduce the myelosuppression seen following the drugs used in this study at the dosages used. Autologous bone marrow transplantation may be useful only in the setting of marrow lethal therapy. Its usefulness in shortening recovery time from nonlethal therapy appears questionable.
