Gastric cancer is found in more than 90% of patients infected with H. Pylori. The symptoms, although not specific, should not be overlooked. Recommended methods for diagnosis and treatment of the disease.
Studies have shown that gastric cancer is related to Helicobacter Pylori. H. Pylori is responsible for causing gastric ulcers and chronic gastritis. Therefore, the pathogenicity of this bacteria may explain the high incidence of gastric cancer in patients infected with H. Pylori. More than 90% of gastric cancers arise from the gastric mucosa. คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย Since the mucosa has glands, gastric cancers arising. From glands are called adenocarcinomas. Most patients present with vague symptoms. Or the disease is detected at an advanced stage.
Stomach cancer symptoms
- Upper abdominal pain
- Loss of appetite
- Intermittent vomiting
- belch
- Eat less food
Symptoms of stomach cancer may be the same as those of patients with stomach ulcers or gastritis, making diagnosis based on symptoms quite difficult. Other symptoms include:
- Vomiting blood
- Have trouble swallowing
- Unexplained weight loss
- tired
- Black photo
Gastric cancer is often found when it has spread. Because it is not diagnosed at an early stage due to the non-specific symptoms mentioned above.
Diagnosis
- Endoscopy is more than 95% effective in diagnosing gastric cancer. Upper gastrointestinal endoscopy is use to diagnose and stage gastric cancer.
- Newer endoscopy models use endoscopic ultrasound (EVS) to provide better insight into the extent of invasion and lymph node metastasis.
- Computed tomography (PET/CT) scans can help to stage the overall disease, but only if the cancer has spread to lymph nodes, liver, lungs, or other organs.
Treatment
- Most early stage gastric cancers are treat with surgery alone.
- Partial gastrectomy is a surgery to remove only part of the stomach.
- Total gastrectomy is a surgical procedure to remove the entire stomach.
- In patients with advanced gastric cancer, if surgery is the only treatment method, the cancer often comes back. In more than 2 out of 3 patients in this group, the cancer will come back with spread to the lymph nodes. In some patients, the cancer recurs and spreads to other organs as well.
- Radiation therapy and chemotherapy are usually recommended for people. With stage 1B or higher gastric cancer (cancer has spread to the stomach wall or has spread to lymph nodes). Treatments that use radiation therapy and chemotherapy tend to have better results.
- The standard chemotherapy use to treat gastric is 5-FU in combination with leucovorin given intravenously. Side effects of 5-FU and leucovorin include nausea, diarrhea, skin discoloration, and mouth sores. Other chemotherapy drugs have been studied, such as cisplatin, oxaloplatin, and epirubicin, but 5-FU and leucovorin remain the standard of care for gastric cancer.
