Several studies have shown that FAP expression was correlated with worse overall survival across a wide range of human cancers,22 including colorectal cancer, clear cell renal cell carcinoma, gastric cancer, intrahepatic cholangiocarcinoma, oral squamous cell carcinoma, ovarian cancer, pancreatic ductal adenocarcinoma, and non‐small cell lung adenocarcinoma.23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34. Here, FAP is linked to ovarian cancer.
