Management and Outcomes of Uterine Smooth Muscle Tumour of Uncertain Malignant Potential (STUMP)

Cancer Medicine, Volume 15, Issue 7, July 2026.
ABSTRACT Background Uterine smooth muscle tumours of uncertain malignant potential (STUMP) is a mesenchymal tumour which does not fulfil the criteria for leiomyoma, benign histological subtypes, or leiomyosarcoma. The risk factors for recurrence and the rates of recurrence vary amongst different studies; as a result, there are currently no consensus ...
