With regard to prognosis, reduced TTC17 expression was also correlated with shorter RFS in ovarian cancer and testicular germ cell tumors, together with dismal OS in bladder carcinoma, pancreatic ductal adenocarcinoma, rectum adenocarcinoma, and stomach adenocarcinoma (Fig. 2b, c, Additional file 2: Fig. S2a-d). This evidence concerns the gene TTC17 and testicular germ cell tumor.
