[Sarcoma of the endometrial stroma].
BACKGROUND: To evaluate the most important risk factors and the efficacy of endometrial stromal sarcoma therapy. METHODS: During a period of 9 years, 5 cases of ESS have been observed at the IInd Obstetrical and Gynecological Institute of the University of Bari. The patients were staged according to the FIGO classification of endometrial carcinoma and studied from an epidemiological, histopatological and clinical point of view. All patients firstly received uterine courettage and then total simple laparohysterectomy. In 4 cases bilateral salpingo-oophorectomy and then polychemotherapy. Only in 1 case total hysterectomy and monolateral salpingo-oophorectomy were performed. RESULTS: Two patients were affected by low grade ESS malignancy respectively at Ib and Ic stage and received only surgery. High grade ESS malignancy was diagnosed in 3 patients at stage IIIa and they received surgery followed by chemotherapy. These 3 patients survived for 14, 25 and 30 months. The other two are still alive, with no evidence of the disease at 25 and 36 months. CONCLUSION: ESS is a rare neoplasm; the low grade malignancy may survive from 80-100%, while the high ones can have a fatal prognosis with exitus in 12-30 months.
