C16.2

Clinical Causes: Genetic predisposition and family history of stomach cancer Helicobacter pylori (H. pylori) bacterial infection, which can cause chronic inflammation Diet high in smoked, salted, or pickled foods Tobacco use and smoking Excessive alcohol consumption Chronic stomach conditions such as gastritis or pernicious anemia Previously undergone stomach surgery Exposure to certain environmental toxins or carcinogens Age, with a higher risk in older adults Poor overall diet and nutritional deficiencies

Key Symptoms: Persistent indigestion or heartburn Unintentional weight loss Feeling full after small meals Nausea or vomiting, sometimes with blood Abdominal pain or discomfort in the upper stomach area Swelling or a mass in the abdomen Difficulty swallowing if the tumor blocks the passage Fatigue and weakness due to anemia or general debilitation Loss of appetite

Diagnosis Path: The diagnosis of malignant neoplasm of the stomach's body typically involves a combination of methods: - Endoscopy: A flexible tube with a camera to examine the stomach lining and obtain tissue samples for biopsy. - Biopsy: Laboratory analysis of tissue samples to confirm cancer and determine its characteristics. - Imaging tests: CT scans, PET scans, or ultrasound to assess the extent of the disease and check for metastasis. - Blood tests: To evaluate overall health, detect anemia, or identify tumor markers. Proper staging through these diagnostic tools is essential for planning effective treatment strategies.

Treatment Protocols: Managing malignant neoplasm of the stomach generally involves a multidisciplinary approach, often including: - Surgery: Partial or total gastrectomy to remove the tumor and affected tissue. - Chemotherapy: Use of drugs to kill cancer cells and reduce tumor size, often used before or after surgery. - Radiation therapy: Targeted radiation to destroy remaining cancer cells, usually in conjunction with other treatments. - Targeted therapy: Medications designed to target specific molecules involved in tumor growth. - Palliative care: Focused on relieving symptoms and improving quality of life when curative treatment isn’t possible. Treatment plans are tailored based on the stage of the cancer, the patient’s overall health, and other individual factors.
