Image showing Gastrointestinal Stromal Tumor after surgical removal. For localized, resectable adult GISTs, if anatomically and physiologically feasible, surgery is the primary treatment of choice. [22]: 69 Surgery can be potentially curative, but watchful waiting may be considered in small tumors in carefully selected situations. [28]
GISTs are most common in individuals ranging in age from 40 years old to 70 years old and are rare in small children and young adults. [2] Individuals with these tumors may experience swelling in the abdomen, pain, vomiting, nausea, appetite loss, weight loss, low blood cell counts, gastrointestinal bleeding (which can result in bloody or dark ...
In a benign tumor, the proliferated cells stay in one location where they do not impact or spread to other surrounding tissues. Malignant tumors, on the other hand, are capable of spreading throughout the entire body, causing new tumors to appear. This process is called metastasis, and is a hallmark of cancerous tumors. [2]
Stomach cancer, also known as gastric cancer, is a cancer that develops from the lining of the stomach. [10] Most cases of stomach cancers are gastric carcinomas, which can be divided into a number of subtypes, including gastric adenocarcinomas. [2] Lymphomas and mesenchymal tumors may also develop in the stomach. [2]
Cancer of the stomach, also called gastric cancer, is the fourth-most-common type of cancer and the second-highest cause of cancer death globally. [2] Eastern Asia (China, Japan, Korea, Mongolia) is a high-risk area for gastric cancer, and North America, Australia, New Zealand and western and northern Africa are areas with low risk. [5]
Owing to the causal relationship between H. pylori infection and gastric MALT lymphoma, identification of the infection is imperative. Histological examination of GI biopsies yields a sensitivity of 95% with five biopsies, [7] but these should be from sites uninvolved by lymphoma and the identification of the organism may be compromised by areas of extensive intestinal metaplasia.
