C16.9

Clinical Causes: Dietary factors, such as high consumption of smoked, salted, or pickled foods Chronic inflammation of the stomach lining (gastritis) Infection with Helicobacter pylori bacteria Lifestyle factors like smoking and excessive alcohol consumption Genetic predisposition and family history of gastric cancer Certain medical conditions, including gastric polyps or previous stomach surgeries Environmental exposures to carcinogens

Key Symptoms: Unintentional weight loss Persistent stomach pain or discomfort Nausea and vomiting, possibly with blood Difficulty swallowing Feeling full quickly after eating Indigestion or heartburn that persists Blood in stool or vomit, which may appear as dark or tarry stools Anemia symptoms like fatigue and weakness due to blood loss

Diagnosis Path: Diagnosing gastric cancer typically involves a series of medical evaluations and tests. These may include endoscopy, where a flexible tube with a camera is inserted into the stomach to visually examine and possibly biopsy suspicious areas. Imaging studies such as CT scans, ultrasound, and barium swallow X-rays help determine the extent of the disease. Laboratory tests, including blood work, can assess overall health and check for anemia or other related issues. Pathological examination of tissue samples confirms the diagnosis and helps determine the cancer type and stage.

Treatment Protocols: Treatment strategies for gastric cancer depend on the cancer stage, location, and the patient’s overall health. Common approaches include surgery to remove part or all of the stomach, chemotherapy to target cancer cells, radiation therapy, or targeted drug therapies. In some cases, palliative care is provided to manage symptoms and improve quality of life. Multidisciplinary teams of healthcare providers coordinate to develop individualized treatment plans, considering the risks and benefits of each option.
