The Kaplan-Meier estimate showed that there is no significant difference of OS and RFS between the low and high PRKAA1 TPM groups in gastric cancer (OS: Log-rank P = 0.48, RFS: Log-rank P = 0.38), breast cancer (OS: Log-rank P = 0.34, RFS: Log-rank P = 0.98), esophageal carcinoma (OS: Log-rank P = 0.096, RFS: Log-rank P = 0.7), and lung adenocarcinoma (OS: Log-rank P = 0.41, RFS: Log-rank P = 0.20). This evidence concerns the gene PRKAA1 and lung adenocarcinoma.
