[Effect of medroxyprogesterone acetate on side effects of CAP therapy in gynecological malignant tumors].
We concomitantly administered a large dose of medroxyprogesterone acetate (MPA) to gynecological malignant tumor patients undergoing CAP therapy (CAP). Hematological changes in the peripheral blood were compared between concomitant MPA patients and those not receiving MPA to examine the effect of MPA in reducing the marrow depression which is the major side effect of CAP. 1) Leukocyte count reached minimum at the second week of CAP in both groups. There was no significant difference in the count between the two groups. At the third week of CAP, the count improved to 84% of the pre-CAP level in patients receiving MPA and to 68% in those not receiving MPA, a significant difference (p less than 0.01). At the fourth week, leukocyte counts were 105% and 96% of pre-CAP levels, respectively. There was no difference between the two groups, but the leukocyte count returned to the pre-CAP level in the patients receiving MPA. 2) Platelet count showed changes similar to those in the leukocyte count. In patients receiving MPA, the count improved more rapidly within three weeks (118%, p less than 0.01), and was significantly higher at the fourth week (107%, p less than 0.05) than in patients not receiving MPA. 3) Reticulocyte count reached minimum in the first week, thereafter improving rapidly in both groups. No differences were noted between the two groups. 4) The periods needed for one course of CAP were 27.7 +/- 3.3 days in the patients receiving MPA and 29.5 +/- 3.7 days in the patients not receiving MPA, making for a significant difference between the two groups (p less than 0.05). These results show that MPA accelerates recovery from marrow depression caused by CAP. It is anticipated, therefore, that MPA will be helpful in the application of various chemotherapies which are expected to be frequently conducted in the future.
