Brief Title: PEComas: Natural History and Prognostic Factors
Official Title: National Multicenter Retrospective Study: PEComas: Natural History and Prognostic
Study ID: NCT03916575
Brief Summary: Perivascular epithelioid cell tumors are rare and characterized by the expression of myomelanocytic markers. They belong to a complex tumor family that includes angiomyolipomas, lymphangioleiomyomatosis and other soft-tissue tumors. Given their rarity, the natural history of pecomas is not yet understood, and a comprehensive classification that integrates clinical, pathological and molecular features has not been achieved as of today. This study is a national multicenter retrospective study to better understand the natural history of PEComas, excluding lymphangioleiomyomatosis and classic triphasic angiomyolipomas. The primary purpose is the identification of prognostic markers impacting the relapse. Secondaries purposes are to identify prognostic markers impacting the overall survival and to have a better understanding of natural history
