In urachal adenocarcinomas, CK7 exhibited a pooled reactivity rate of 51%, compared to considerable lower rates in colorectal cancer (0–38%, Table 2, Supplementary Table 2) [1, 17, 23, 26, 27, 31, 36, 48, 56, 60, 67, 74, 77, 86, 99, 124, 125, 156, 163, 164, 216, 217, 220, 240, 251, 255, 292, 327, 328]. This evidence concerns the gene KRT7 and bladder urachal adenocarcinoma.
