In addition, cAT levels clearly associated with CEA levels in the blood of patients with breast carcinomas (p = 0.032), CA199 levels in those with gastric cancer (p = 0.025), CEA levels in those with pancreatic cancer (p = 0.05), CA125 levels in those with ovarian cancer (p = 0.03), CEA levels in those with bladder cancer (p = 0.016), CEA in those with renal cell carcinomas (p = 0.046), and PSA in those with prostate cancer (p = 0.028). This evidence concerns the gene CAT and hereditary clear cell renal cell carcinoma.
