MSCT Diagnosis And Clinical Significance Of Gastric Cancer And Colorectal Metastases

Objective:to analyze MSCT of gastric cancer and colorectal metastases and MSCT examination, summarizes the morphological characteristics of gastric cancer and colorectal metastases, strengthening characteristics, pathological classification, to improve the understanding of colorectal metastases of gastric cancer, improve the diagnostic accuracy.Methods:select nearly three years the collected 50 cases by clinical surgery or endoscopic in hospitalized patients diagnosed with stomach cancer colorectal metastases as the research object.17 patients with 33 patients with which men and women, aged 28-79-s, the average age was (42.1+/-5.1).50 cases of patients were retrospectively analyzed and data records, including the basic information of the patients with primary record, gastric cancer and colorectal metastases of MSCT manifestations and pathological features, such as:patients’age, sex, tumor site, tumor size, strengthening characteristics and morphology, histology, etc.Results: ① 50 patients with gastric cancer, the cancer occurs in cardia area of 20 cases, distal gastric area 15 cases,6 cases of stomach, the stomach body is little side in 5 cases,4 cases were gastric body greater curvature side. Signet ring cell carcinoma in 12 cases,14 cases of poorly differentiated adenocarcinoma, poorly differentiated adenocarcinoma and signet ring cell carcinoma is,15 cases at the same time.②Each part of the gastric cancer patients with cancer of the stomach wall thickness than normal adult stomach wall thickness were significantly increased, the stomach stomach wall thickness range 9.82 ～35.90 mm. ③ Colorectal metastases of bowel wall thickening of CT manifestations:50 cases of patients with 76 lesions, the five not seen obvious thickening of bowel wall; 71 the thickness of the bowel wall thickening and greater than 5 mm, the average thickness of 16.5 mm. Thickening of the uniform type 40,20 non-uniform thickening type, lumen endogenous mass type 6, lumen protruding mass type 5. Lumen diameter of 25.0 mm of endogenous type mass lesions, protruding mass type is 27.8 mm. ④olorectal metastases of unofficial CT enhancement performance:all lesions in uniformity is improved 15; Not uniformity strengthening 10; Stratified sample strengthened 51, of which a high-low-high from inner to outer hierarchical reinforcement 27 place, high-low hierarchical reinforcement 16 place, low-Gao Jianghua 3 place, strengthen the five place more than three layer. High density layer and inner layer markedly thickened at 43, the middle layer or outer layer low density layer markedly thickened 8. ⑤ 17 in the patients with women in 7 cases (52.2%) patients with ovarian metastases.Conclusion:colorectal metastases of gastric cancer pathological types are mainly low differentiated adenocarcinoma and signet ring cell carcinoma, Borrmann type is given priority to with Ⅲ, Ⅳ type. And checked with MSCT in patients with gastric cancer diagnosis, the method is rapid accurate, so we should make is widely used in clinic. In addition, with mirnas therapy (anti-mirna) become a potentially effective way to cancer therapy, MSCT for the early diagnosis of gastric cancer and its treatment of the colorectal cancer metastasis, accurate diagnosis is important.
