PTEN and cancer: The endpoint of the survival analysis was overall survival (OS) and disease-free survival (DFS) (when available), and all datasets were partitioned by deep PTEN deletions (i.e., PTEN loss, Genomic Identification of Significant Targets In Cancer (GISTIC) score < −1) or with deep and shallow PTEN deletions (i.e., PTEN Del, GISTIC score < 0) [118].
