Collection of clinical manifestations of gastric cancer

[Clinical]
1, on the early days of abdominal pain or discomfort for pain, have advanced pain. No pain regularity, but heavier meal, but also some pain in patients with ulcer-like disease can be alleviated by using acid agent.
2, Baozhang upper abdominal discomfort.
3, anorexia, anorexia greasy meat, but whose favorite diet, despite eating as usual, there was a late anorexia.
4, cardia cancer can be expressed as swallowing, Xiphoid under obstruction flu.
5, disease progression to advanced, there may be loss of appetite, weight loss, anemia, pyloric obstruction, sustained and feces, ascites, abdominal mass, evil-MS symptoms.
6, no early signs.
Advanced:
(1) abdominal mass in the abdomen more, the quality of hard (sometimes resembles liver Zhizuo leaves, easily mistaken as liver cancer or cirrhosis).
(2) transfer performance can be left supraclavicular lymph nodes got quality hardware; cancer ascites; cancer metastasis to the liver, lung, ovarian, and other emerging
Corresponding signs and symptoms.
(3) Upper gastrointestinal barium meal examination positive rate of more than 90%, common are:
① filling defect; ② cavity niche, ulcers usually greater than 2.5 cm in diameter, the external environment and see crescent shadow, not the edge of nearby mucosal folds rough chaos, interrupted or disappear; ③ stenosis and obstruction. X-ray examination in recent years because of improved methods, such as the use of double photography, we can observe the mucosal folds the existence of micro-gap lesions, which can be found that the majority of early gastric cancer.
(4) endoscopy and gastric mucosa in vivo cytology both fiber endoscopy or electronic endoscopy are an important basis for the diagnosis of gastric cancer, a pathological examination in vivo diagnosis of gastric cancer is the single most direct indicators.
(5) cytology examination of the stomach gastric cancer diagnosis also contributed.
(6) laboratory tests.
① about half of patients with fecal occult blood was repeatedly positive.
② erythrocyte sedimentation rate of about 2 / 3 of patients with growth.
③ about 20 percent of gastric acid-free, and the remaining acid was low or normal acidity.
The above three more checks early, the positive rate low, thus can not be considered normal results of this disease can be ruled out.
④ a variety of other laboratory tests such as immunization inspection carcinoembryonic antigen (CEA), alpha-fetoprotein (aFP), the specificity of the diagnosis of gastric cancer are not high. Monoclonal antibody to detect gastric cancer, or gastric stomach cancer antigen in the serum of the methodology is actively study, so far no breakthrough progress.
