What examination does gastric cancer need to do
summary
The symptoms of gastric cancer are similar to many stomach diseases. My second uncle often had nausea and vomiting at that time. Later, he was diagnosed after systematic examination. Let's take a look at the tests for gastric cancer.
What examination does gastric cancer need to do
One: normal gastric juice analysis, colorless or light yellow gastric juice, free hydrochloric acid about 0 ~ 10u per 100ml gastric juice, total acidity about 10 ~ 50U. About 65% of gastric cancer patients showed gastric acid deficiency, while 200% - 25% of gastric cancer patients still showed gastric acid deficiency after pentagastrin stimulation. The degree of gastric acid deficiency is often proportional to the size of gastric cancer. The degree of gastric acid deficiency in invasive cancer and gastric fundus and cardia cancer is more severe than that in pyloric cancer. When gastric cancer causes pyloric obstruction, a large amount of food residue can be found. If accompanied with bleeding, coffee like liquid can appear, which has certain significance for the diagnosis of gastric cancer.
Second, fecal occult blood test is persistent positive, which has reference value for the diagnosis of gastric cancer, and can provide clues for the discovery of gastric cancer. The positive rate of fecal occult blood test in early superficial gastric cancer can reach 20%, and with the progress of the disease, the positive rate can reach more than 80%, among which the positive rate of gastric body cancer is the highest, followed by cardiac cancer.
Third, there are many methods of immunological diagnosis, which have been used in clinic in China. Monoclonal antibodies (mAbs) derived from hybridoma cell lines established by cell fusion have been used in the diagnosis and treatment of tumors at home and abroad. The research of monoclonal antibodies in the diagnosis of gastric cancer started earlier, and some of them have been used in clinic.
matters needing attention
The prognosis of gastric cancer is related to pathological stage, location, histological type, biological behavior and treatment. The prognosis of early gastric cancer after treatment is better, in the discovery of the disease, we must timely treatment, strive to get the best control.
