title: In vitro functions of lymphocytes during high-dose medroxyprogesterone acetate (MPA) treatment.
abstract: The number and function of T and B lymphocytes were studied in endometrial cancer patients during 3 months' treatment with high-dose medroxyprogesterone acetate (MPA). No significant changes were observed in the proportions of T and B cells or in the function of B cells during MPA treatment. At 3 months, lymphocyte blastogenic responsiveness to mitogens was slightly reduced both in patients treated with standard therapy alone (intracavitary radium and surgery) and in patients receiving additional MPA therapy. These results indicate that other factors than progesterone are responsible for the suppression of lymphocyte blastogenesis induced by mitogens during high-dose progestin treatment.
