Differential diagnosis of gastric cancer:

1. Physical signs: There are no special signs in the early stage, but in the late stage, a mass can be seen in the upper abdomen. The mass can be felt during rectal examination, and the left supraclavicular lymph nodes are enlarged. At the same time, there are cachexia symptoms such as anemia, weight loss, and ascites.

In the late stage, fatigue, back pain, and nausea, vomiting, and difficulty eating may occur after obstruction. Ulcers on the surface of the tumor may cause vomiting of blood and black stools.

3. X-ray: Double contrast of gas and barium can clearly show the gastric contour, peristalsis, mucosal morphology, emptying time, filling defects, niches, etc. The accuracy of the examination is nearly 80%.

4. Immunology: CEA, FSA, GCA, YM globulin and other tests.

5. Ultrasound: It can be used to understand whether there is metastasis to surrounding solid organs.

6. CT examination: to understand the invasion of gastric tumor, its relationship with surrounding organs, and whether resection is possible.

7. Fiber endoscopy: It is the most direct, accurate and effective method for diagnosing gastric cancer.

8. Exfoliative cytology: Some scholars advocate this examination when clinical and X-ray examinations reveal suspected gastric cancer.

9. Laboratory examination: Early suspected gastric cancer, low or absent free gastric acid, such as decreased hematocrit, hemoglobin, and red blood cells, occult blood in stool (+), low total hemoglobin, inverted white blood cells, etc. Abnormal test results such as water and electrolyte disorders and acid-base imbalance.
