What are the diagnostic criteria for gastrointestinal cancer

Gastrointestinal cancer is a very common tumor disease, threatening the health of patients. Many people do not fully understand the diagnostic criteria for gastrointestinal cancer, which is very unfavorable for future treatment and rehabilitation. So what are the diagnostic criteria for gastrointestinal cancer? Let's take a look at the relevant diagnostic criteria!

(I) Symptoms: Early symptoms include upper abdominal discomfort, which occurs in about 80% of patients, and nearly 50% of gastric cancer patients have obvious loss of appetite or loss of appetite. 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.

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

(III) Laboratory examinations for 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 tests such as water and electrolyte disorders and acid-base imbalance.

(IV) X-ray manifestations: Double contrast gastrointestinal imaging can clearly show the gastric contour, peristalsis, mucosal morphology, emptying time, filling defects, niches, etc. The accuracy of the examination is nearly 80%.

(V) Fiber endoscopy is the most direct, accurate and effective method for diagnosing gastric cancer.

(VI) Exfoliative cytology examination: Some scholars advocate this examination when clinical and X-ray examinations are suspected of gastric cancer.

(VII) B-ultrasound can be used to determine whether there is metastasis to surrounding solid organs.

(8) CT examination is used to understand the invasion of gastric tumors, their relationship with surrounding organs, and whether resection is possible.

(IX) Immunological examinations such as CEA, FSA, GCA, and YM globulin.

Only in the early stage of the disease, if you have an accurate understanding of your condition, can you choose a treatment method that is truly suitable for you. Therefore, relevant doctors remind friends of gastric cancer patients to go to a regular hospital for a comprehensive and systematic physical examination to ensure that patients receive the most effective treatment.
