Surgical Treatment for Stomach Cancer: Is Gastrectomy a Viable Option?

Stomach cancer, also known as gastric cancer, is a malignancy that affects the stomach lining. It is the fifth most common cancer worldwide, with an estimated 1 million new cases and 783,000 deaths in 2018 alone (Bray et al., 2018). The mainstay of treatment for stomach cancer is surgery, which involves removing the cancerous tissue and a portion of the surrounding healthy tissue. However, in some cases, this may require removing the entire stomach, a procedure known as gastrectomy. This article explores the viability of gastrectomy as a treatment option for stomach cancer.

Types of Gastrectomy

There are three types of gastrectomy: total gastrectomy, subtotal gastrectomy, and proximal gastrectomy. Total gastrectomy involves removing the entire stomach, whereas subtotal gastrectomy involves removing only the cancerous part of the stomach and a portion of the surrounding healthy tissue. Proximal gastrectomy involves removing the upper portion of the stomach (near the esophagus) and preserving the lower portion. The choice of gastrectomy depends on the location and stage of the cancer, as well as the patient's overall health.

Risks and Benefits of Gastrectomy

Gastrectomy is a major surgery that carries significant risks and potential complications. These include bleeding, infection, blood clots, pneumonia, and anastomotic leak (a leak in the site where the remaining stomach is attached to the small intestine). In addition, gastrectomy can result in long-term side effects such as malnutrition, dumping syndrome (a condition in which food moves too quickly from the stomach to the small intestine), and weight loss.

Despite these risks, gastrectomy can offer several benefits for patients with stomach cancer. Firstly, it can remove the entire cancerous tissue and reduce the risk of cancer recurrence. Secondly, it can alleviate the symptoms of stomach cancer, such as nausea, vomiting, and abdominal pain. Thirdly, it can improve the patient's quality of life by allowing them to resume normal activities, such as eating and drinking, albeit in smaller portions and more frequent meals.

Postoperative Care and Follow-Up

After gastrectomy, patients require close postoperative care and follow-up to monitor for potential complications and ensure proper healing. This includes pain management, nutrition support, fluid and electrolyte balance, and wound care. In addition, patients may require long-term nutritional and dietary counseling to prevent malnutrition and dumping syndrome.

Follow-up care also involves regular imaging studies and laboratory tests to detect any signs of cancer recurrence. The frequency and duration of follow-up depend on the stage and type of stomach cancer, as well as the patient's response to treatment.

Conclusion

Gastrectomy is a viable treatment option for patients with stomach cancer, particularly those with advanced or aggressive tumors. However, it is a major surgery that carries significant risks and potential complications. Therefore, the decision to undergo gastrectomy should be made after careful consideration of the risks and benefits, in consultation with a multidisciplinary team of oncologists, surgeons, and other specialists. With proper postoperative care and follow-up, patients can achieve good outcomes and improve their quality of life after gastrectomy.
