RESUMEN
We investigated the clinical effect of Juzen-taiho-to and macrophage-colony stimulating factor (M-CSF) on thrombocytopenia induced by anti-cancer chemotherapy in gynecologic malignancies. We discussed 31 courses in 20 patients. Juzen-taiho-to and/or M-CSF were given when indicated from serum platelet level. Twenty-eight courses (90.3%) in 17 patients did not need transfusion of platelet, and 3 courses in 3 patients needed it. It suggested that Juzen-taiho-to and M-CSF might be effective. As platelet-free plasma TGF-β1 level during the treatment of Juzen-taiho-to alone was remarkably increased, it might enhance the antitumoral action. Accordingly, combination treatments of Juzen-taiho-to and M-CSF might be effective for thrombocytopenia induced by anti-cancer chemotherapy.
