title: Progestin therapy in lesions of the endometrium.
abstract: This paper details several studies of the effect of a single progestin, megestrol acetate, in patients with persistent endometrial hyperplasia and recurrent or persistent endometrial adenocarcinoma. Results of these studies indicate that megestrol acetate inhibits recurrence of adenomatous and atypical hyperplasia as well as adenocarcinoma in situ. These diseases when left untreated often progress to invasive adenocarcinoma. Additional studies presented here show that megestrol acetate is effective in the treatment of endometrial adenocarcinoma in inoperable patients and increases survival in patients with recurrent endometrial cancer.
