Understanding Gastric Cancer: Causes, Symptoms, and Treatment Options

Gastric cancer, commonly known as stomach cancer, is a malignancy that originates in the lining of the stomach. The types of gastric cancer vary depending on the cells involved, with adenocarcinoma being the most prevalent, accounting for the majority of cases. Other types include lymphoma, gastrointestinal stromal tumors (GIST), and carcinoid tumors. While the precise cause of gastric cancer remains unclear, several factors are known to increase the risk of developing this condition. These include infection with Helicobacter pylori, smoking, a diet high in smoked, salted, or pickled foods, obesity, and certain genetic predispositions such as Lynch syndrome and familial adenomatous polyposis (FAP).

Recognizing the risk factors for gastric cancer is crucial for early detection and prevention. Age is a significant factor, with most cases occurring in individuals over 55. Men are twice as likely to develop gastric cancer compared to women. A family history of gastric cancer, chronic gastritis, pernicious anemia, or intestinal metaplasia also heightens the risk. Initial symptoms of gastric cancer are often vague and nonspecific, which can delay diagnosis. Common symptoms include persistent indigestion, stomach pain, nausea, loss of appetite, unexplained weight loss, difficulty swallowing, and blood in the stool. As the disease progresses, these symptoms can intensify, leading to complications such as gastrointestinal bleeding or obstruction.

Treatment options for gastric cancer depend on the stage and location of the tumor, as well as the overall health of the patient. Early-stage gastric cancer may be treated with endoscopic resection, a procedure that involves removing the tumor using an endoscope. In more advanced stages, surgical options such as subtotal or total gastrectomy, where part or all of the stomach is removed, may be necessary. Chemotherapy and radiation therapy are often employed alongside surgery to improve outcomes. Emerging treatments like targeted therapy, which focuses on specific cancer cells, and immunotherapy, which enhances the body’s immune response against cancer, are also available.

Surgical management of gastric cancer is complex and requires a multidisciplinary approach. Preoperative assessment and preparation are essential to optimize patient outcomes. Postoperative care involves close monitoring for complications such as infections, leaks at the surgical site, and nutritional deficiencies. Nursing care plans for gastric cancer patients focus on managing symptoms, providing nutritional support, and offering psychological support. Nurses play a vital role in educating patients about their condition, treatment options, and the importance of follow-up care. Pain management, wound care, and monitoring for signs of recurrence are also critical components of nursing care.
