At the next step, we asked whether COL1A1 and COL5A1 increase the poor prognostic impact of CAF infiltration in four cancers (adrenocortical carcinoma, bladder urothelial carcinoma, kidney renal papillary cell carcinoma, and mesothelioma) with a poor outcome profile for the six CAF markers and CAF infiltration like gastric cancer. The gene discussed is COL5A1; the disease is cancer.
