How to find the early symptoms of gastric cancer?

summary

In the early stage of gastric cancer, more than 70% of the patients have no symptoms, and the patients with symptoms are generally atypical. Mild epigastric discomfort is the most common initial symptom, similar to dyspepsia or gastritis. At present, there is no specific tumor marker for the diagnosis of gastric cancer. Continuous monitoring of CEA, CA50, CA72-4, CA19-9, CA242 and other markers has a certain value for the diagnosis, treatment and prognosis of gastric cancer. How to find the early symptoms of gastric cancer? Let's talk about it.

How to find the early symptoms of gastric cancer?

Diffuse cancer: when the cancer infiltrates the gastric wall extensively, it can make the gastric wall thicken widely, the gastric wall stiff, barium excretion is fast, and the gastric cavity shrinks and narrows, which is only 1 / 3 or smaller than the original, just like a leather bag.

Mass type gastric cancer: the tumor protrudes to the gastric cavity, where barium can not be filled, forming a defect area in barium, showing filling defects of different sizes and shapes, characterized by irregular edges, stiffness of the gastric wall at the lesion, and no peristalsis.

Ulcerative gastric cancer: there is a shadow protruding out of the barium outline, which is called niche. The niche is large and shallow, and the edge is uneven.

matters needing attention

Follow up of high-risk groups, such as patients with chronic atrophic gastritis, gastric ulcer, gastric polyps, moderate and severe intestinal metaplasia and atypical hyperplasia, and patients with a history of gastric cancer in their immediate family members, all belong to high-risk groups of gastric cancer. This method is more economical and effective than census.
