Stomach cancer, also known as gastric cancer, is a leading cause of cancer-related deaths worldwide. According to the International Agency for Research on Cancer (IARC), stomach cancer is the fifth most common cancer and the third leading cause of cancer death globally, with approximately 1.1 million new cases and 770,000 deaths reported in 2020. In recent years, there have been significant advances in stomach cancer treatments, offering new hope to patients and their families. This article aims to provide an overview of the current state of stomach cancer treatment, highlighting the latest developments and what patients need to know.
The treatment of stomach cancer has evolved significantly over the years, with a better understanding of the disease biology and the development of new therapeutic approaches. Surgery remains the primary treatment for stomach cancer, but it is often used in combination with other treatments, such as chemotherapy, radiation therapy, and targeted therapy. In this article, we will discuss the current treatment options for stomach cancer, including the latest advances in surgical techniques, chemotherapy, radiation therapy, and targeted therapy.
Understanding Stomach Cancer
Stomach cancer is a type of cancer that originates in the stomach, which is a vital part of the digestive system. The stomach is responsible for breaking down food into smaller particles that can be absorbed by the body. Stomach cancer can occur in any part of the stomach, but it is most common in the lower part of the stomach, near the junction with the small intestine.
The exact causes of stomach cancer are not fully understood, but several risk factors have been identified, including Helicobacter pylori infection, smoking, obesity, and a family history of stomach cancer. Symptoms of stomach cancer may include abdominal pain, weight loss, loss of appetite, and fatigue. If left untreated, stomach cancer can lead to serious complications, such as bleeding, obstruction, and perforation.
Current Treatment Options for Stomach Cancer
The treatment of stomach cancer depends on the stage of the disease, the overall health of the patient, and other factors. The main treatment options for stomach cancer include surgery, chemotherapy, radiation therapy, and targeted therapy.
Surgery
Surgery is the primary treatment for stomach cancer, and it involves removing the tumor and surrounding tissue. The goal of surgery is to remove the cancer completely, which can be curative if the cancer is caught early. There are several types of surgery that can be used to treat stomach cancer, including:
- Gastrectomy: This is the surgical removal of part or all of the stomach.
- Subtotal gastrectomy: This involves removing the lower part of the stomach.
- Total gastrectomy: This involves removing the entire stomach.
Chemotherapy
Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. It is often used in combination with surgery to shrink the tumor before surgery or to kill any remaining cancer cells after surgery. Chemotherapy can be administered orally or intravenously, and it can have side effects such as nausea, vomiting, and fatigue.
Recent advances in chemotherapy have led to the development of new drugs and regimens that have improved treatment outcomes. For example, the use of fluoropyrimidine-based chemotherapy has been shown to improve survival rates in patients with stomach cancer.
Radiation Therapy
Radiation therapy is a type of cancer treatment that uses high-energy rays to kill cancer cells. It can be used to shrink the tumor before surgery or to kill any remaining cancer cells after surgery. Radiation therapy can be administered externally or internally, and it can have side effects such as fatigue, nausea, and diarrhea.
Targeted Therapy
Targeted therapy is a type of cancer treatment that targets specific genes or proteins that are involved in the growth and spread of cancer cells. It can be used to treat stomach cancer that has spread to other parts of the body or to treat cancer that has come back after treatment.
Recent advances in targeted therapy have led to the development of new drugs that have improved treatment outcomes. For example, the use of trastuzumab has been shown to improve survival rates in patients with HER2-positive stomach cancer.

Advances in Stomach Cancer Treatments
Recent advances in stomach cancer treatments have improved treatment outcomes and offered new hope to patients and their families. Some of the latest developments include:
Immunotherapy
Immunotherapy is a type of cancer treatment that uses the body's immune system to fight cancer. It has been shown to be effective in treating several types of cancer, including stomach cancer. Immunotherapy can be used to treat stomach cancer that has spread to other parts of the body or to treat cancer that has come back after treatment.
Precision Medicine
Precision medicine is a type of cancer treatment that uses genetic testing to identify specific genes or proteins that are involved in the growth and spread of cancer cells. It can be used to develop personalized treatment plans that are tailored to the individual patient's needs.
Minimally Invasive Surgery
Minimally invasive surgery is a type of surgery that uses small incisions and specialized instruments to remove the tumor and surrounding tissue. It can be used to treat stomach cancer that is caught early, and it can offer several benefits, including less pain, less scarring, and a faster recovery time.
| Stomach Cancer Treatment | 5-Year Survival Rate |
|---|---|
| Surgery alone | 30-40% |
| Surgery + chemotherapy | 40-50% |
| Surgery + radiation therapy | 45-55% |
| Targeted therapy | 20-30% |
