PRKDC and uterine corpus endometrial carcinoma: PRKDC amplification also significantly correlated with poor patient survival in multiple cancer types (sarcoma [SARC]: CNAmp frequency = 35.2% [89 of 253], HR = 2.15, 95% CI 1.46 to 3.18, P = 1.12×10-4; uterine corpus endometrial carcinoma [UCEC]: CNAmp frequency = 31.5% [165 of 523], HR = 1.72, 95% CI 1.21 to 2.44, P = 2.50×10-3) (Figure 3D).
