This analysis revealed that the same variables of tumor stage (HR: 1.79, 95% CI: 1.03–3.11), receipt of chemotherapy (HR: 1.64, 95% CI: 1.13–2.37), and CDKN2A copy number loss (HR: 1.51, 95% CI: 1.06–2.16) were independently associated with poor survival (Table 3). The gene discussed is CDKN2A; the disease is neoplasm.
