Spontaneous regression in gynecologic neoplasia

As I have tried to tabulate and evaluate the cases of spontaneous regression of gynecologic malignancy, several facts stand out: 1) They were infrequent. 2) The tumors most commonly undergoing spontaneous regression were the germinal epithelial tumors of the ovary; there was not any case of spontaneous regression of any other variety of ovarian neoplasm. 3) There was not one legitimate case of spontaneous regression of an invasive epidermoid carcinoma of the vulva, vagina, or uterus.
