Genomic alterations in uterine leiomyosarcomas: Potential markers for clinical diagnosis and prognosis

Abstract excerpt

Genomic alterations were analyzed in 21 uterine leiomyosarcomas (ULMSs) by comparative genomic hybridization. DNA copy number changes were detected in all 21 tumors. The most frequent losses were 13q (16/21 = 76%), 10q (13/21 = 62%), 16q (8/21 = 38%), 12p (7/21 = 33%), and 2p (9/21 = 43%). The most common gains were 17p (8/21 = 38%), Xp (7/21 = 33%), and 1q (7/21 = 33%). High-copy-number gains (ratio > 1.5) were...
