Analysis of cases of smooth muscle tumors of the uterus with uncertain malignant potential (STUMP) at the SI «Republican research center for radiation medicine and human ecology»

The article is devoted to the analysis of cases of uterine smooth muscle tumors with undetermined malignant potential (STUPM), identified in the State Institution «Republican Scientific and Practical Center of Russian Medical Research and Emergencies» in the period from 2017 to 2024. The proportion of tumor among all patients operated on for leiomyoma during the indicated period was 0,38%. The average age was 43 (32-45) years. Clinical manifestations of the disease and ultrasound characteristics of the tumor were identical to uterine leiomyoma. Pathological criteria for STUMP are difficult to identify and were rarely established intraoperatively (20% of cases). During the observation period, no cases of tumor recurrence or metastasis were detected. Considering the rarity of the tumor and the complexity of preoperative diagnosis, there was no uniform protocol for patient management.
