Peptic ulcers with CA199 greater than 1000 are highly suggestive of malignant tumors of the digestive tract, including ulcerative gastric cancer and ulcerative colorectal cancer.
Ulcers refer to defects in the mucosa and submucosal tissues of the digestive tract, which can be divided into benign ulcers and malignant ulcers in terms of pathological nature. Benign ulcers include peptic ulcer, ulcerative colitis, intestinal amebic ulcer, etc. Certain malignant tumors of the digestive tract can also manifest as ulcers, such as gastric ulcerative gastric cancer and ulcerative colorectal cancer.
CA199 is a tumor marker, which should be lower than 37,000 U/L in normal people, and its elevation can be seen in many digestive malignant tumors, such as pancreatic cancer, gastric cancer, colorectal cancer, cholangiocarcinoma and so on.
Peptic ulcer with elevated CA199 should be highly suspected of malignant tumors, and it is recommended that patients undergo endoscopic tissue biopsy and send it to pathology for clear diagnosis, and then treat it in time without delay to avoid the progression of the disease.
