title: Uterine leiomyosarcoma and endometrial stromal sarcoma: lymph node metastases and sites of recurrence.
abstract: This study was undertaken to examine the incidence and conditions under which lymph node metastases are present and patterns of recurrence in women with uterine leiomyosarcoma (LMS) and endometrial stromal sarcoma (ESS), excluding malignant mixed mesodermal tumors. From 1981 through 1991, 21 women with LMS and 10 women with ESS were treated. Retroperitoneal lymph node dissections were performed in 15 women with LMS and 7 women with ESS. In the women with LMS, 4/15 (26.7%) had lymph node metastases; in each there was disseminated intra-abdominal disease. In the 7 women with ESS, there were no lymph node metastases present. Ten women (47%) with LMS developed recurrences, and 3 (14%) had persistent disease. In the 10 women with ESS, 3 (30%) had recurrences, and 1 (10%) had persistent disease. In total, recurrences involved the lung in 84% of cases. Of the 13 women with recurrences, 7 had undergone lymph node sampling, and all were negative; 4 additional women had no evidence of adenopathy on abdominal-pelvic CT scan. Lymph node metastases were found only with extrauterine disease, and in all of these cases there was rapid progression of the sarcoma. Women without extrauterine disease did not have lymph node metastases detected; however, there was still a high rate (40%) of distant failure. Knowledge of lymph node status had minimal impact on the clinical management of women with uterine LMS and ESS.
