From: Chromosomal imbalance in the progression of high-risk non-muscle invasive bladder cancer
Kaplan Meier estimates of progression-free survival according to chromosomal instability (CI). Tumors are divided in stable and unstable using a cut-off for the fraction of the genome altered (FGA) > 0.05. Here, the influence of the time to progression, not the relative size of the FGA is analysed. Logrank-tests for differences between progressing and non-progressing tumors showed no significant difference. A: all tumors, CI based on copy number changes (n = 46). B: all tumors, CI based on LOH (n = 47). C: Stage T1 tumors only, CI based on copy number changes (n = 32). D: Stage T1 tumors only, CI based on LOH (n = 33).
