title: Malignant peritoneal cytology in stage I endometrial adenocarcinoma: the effect of progesterone therapy (a preliminary report).
abstract: From February 1982-June 1986, 25 consecutive patients with surgical stage I endometrial adenocarcinoma (no evidence of metastasis at surgery or occult cervical or adnexal involvement on histopathologic review) and malignant peritoneal cytologic washings were treated with progesterone therapy. Twenty-two patients have undergone a second look laparoscopy and repeat cytologic washings, one of those also underwent a third look laparoscopy. Two patients refused second look laparoscopy, and in a third patient laparoscopy was medically contraindicated; all three have no evidence of disease (NED) at 15, 46, and 64 months respectively and are off therapy. Of the 22 patients who underwent second look laparoscopy, 21 (95%) had no macroscopic evidence of recurrent endometrial carcinoma and repeat negative peritoneal cytology; 1 patient (5%) had persistent malignant peritoneal cytology but was NED at third look laparoscopy one year later. All 25 patients are off progesterone therapy and remain clinically NED from 12-64 months. Although progesterone therapy for malignant peritoneal cytology resulted in a 100% reversal of malignant peritoneal cytology to normal in the 22 patients who underwent second or third look laparoscopy and all 25 patients remain clinically NED, the true value of progesterone therapy can only be ascertained by a randomized trial of progesterone versus no therapy.
