Evaluation of New Biomarkers Predictive of Efficacy Betablockers in PEComa and Vascular Pediatric Tumors

Completed
Conditions
PEComa
Hemangioma
Registration Number
NCT02334930
Lead Sponsor
University Hospital, Bordeaux
Brief Summary

PEComa is rare tumor affecting particularly patients with Tuberous Sclerosis. Biological similarities were seen between PEComa and infantile hemangioma. Propranolol is highly efficient to treat infantile hemangioma and we believe that this drug can also be useful for the treatment of PEComa.

Purpose : to understand the mechanism of action of propranolol in PEComas and related pediatric vascular lesions and to select possible novel targets of betablockers in vascular tumors related to PEComas by using YAP oncogene activation as a molecular marker
