Stomach cancer, also known as gastric cancer, is a type of cancer that develops in the stomach lining. It is a serious disease that can be life-threatening if not treated promptly and effectively. The treatment of stomach cancer typically involves a combination of surgery, chemotherapy, and radiation therapy. In this article, we will discuss the different treatment options for stomach cancer, their benefits and risks, and the importance of early detection and diagnosis.
Surgery
Surgery is often the primary treatment for stomach cancer, especially if the cancer is localized and has not spread to other parts of the body. The goal of surgery is to remove the tumor and a portion of the stomach lining, as well as any affected lymph nodes. There are several types of surgery that may be performed, including:
- Gastrectomy: This is the surgical removal of part or all of the stomach. The extent of the removal depends on the location and size of the tumor.
- Subtotal gastrectomy: This is a surgical procedure that removes the upper portion of the stomach, leaving the lower portion intact.
- Total gastrectomy: This is a surgical procedure that removes the entire stomach, and the small intestine is connected to the esophagus.
- Lymphadenectomy: This is a surgical procedure that removes lymph nodes in the abdomen that may contain cancer cells.
Chemotherapy
Chemotherapy is a type of cancer treatment that uses medications to kill cancer cells. It may be used before or after surgery to help shrink the tumor or eliminate any remaining cancer cells. Chemotherapy may also be used to treat stomach cancer that has spread to other parts of the body. There are several types of chemotherapy medications that may be used to treat stomach cancer, including:
- Fluorouracil (5-FU): This is a commonly used chemotherapy medication that interferes with the growth of cancer cells.
- Capecitabine (Xeloda): This is an oral chemotherapy medication that is converted into 5-FU in the body.
- Oxaliplatin (Eloxatin): This is a chemotherapy medication that interferes with the growth of cancer cells by damaging their DNA.
- Docetaxel (Taxotere): This is a chemotherapy medication that interferes with the growth of cancer cells by disrupting their cell division.
Radiation Therapy
Radiation therapy is a type of cancer treatment that uses high-energy rays to kill cancer cells. It may be used before or after surgery to help shrink the tumor or eliminate any remaining cancer cells. Radiation therapy may also be used to treat stomach cancer that has spread to other parts of the body. There are several types of radiation therapy that may be used to treat stomach cancer, including:
- External beam radiation therapy (EBRT): This is a type of radiation therapy that uses a machine outside the body to deliver radiation to the tumor.
- Internal radiation therapy (brachytherapy): This is a type of radiation therapy that uses a small amount of radioactive material that is placed inside the body near the tumor.
Targeted Therapy
Targeted therapy is a type of cancer treatment that uses medications to target specific molecules that are involved in the growth and spread of cancer cells. There are several types of targeted therapy medications that may be used to treat stomach cancer, including:
- Trastuzumab (Herceptin): This is a medication that targets the HER2 protein, which is found on some stomach cancer cells.
- Ramucirumab (Cyramza): This is a medication that targets the VEGF receptor, which is involved in the growth of new blood vessels that feed the tumor.
Immunotherapy
Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancer. There are several types of immunotherapy medications that may be used to treat stomach cancer, including:
- Pembrolizumab (Keytruda): This is a medication that targets the PD-1 protein, which is involved in the immune system’s ability to recognize and attack cancer cells.
- Nivolumab (Opdivo): This is a medication that targets the PD-1 protein, which is involved in the immune system’s ability to recognize and attack cancer cells.
Treatment by Stage
The treatment of stomach cancer depends on the stage of the disease. The stages of stomach cancer are:
- Stage 0: This is the earliest stage of stomach cancer, where the cancer is limited to the mucosa (the innermost layer of the stomach lining).
- Stage I: This stage involves the mucosa and the submucosa (the layer of tissue beneath the mucosa).
- Stage II: This stage involves the mucosa, submucosa, and the muscularis propria (the layer of muscle that surrounds the stomach).
- Stage III: This stage involves the mucosa, submucosa, muscularis propria, and the serosa (the outermost layer of the stomach).
- Stage IV: This is the most advanced stage of stomach cancer, where the cancer has spread to other parts of the body, such as the liver, lungs, or lymph nodes.
Treatment Options by Stage
- Stage 0: The treatment for stage 0 stomach cancer is usually endoscopic mucosal resection (EMR) or laparoscopic surgery.
- Stage I: The treatment for stage I stomach cancer is usually surgery, such as gastrectomy or subtotal gastrectomy.
- Stage II: The treatment for stage II stomach cancer is usually surgery, such as gastrectomy or subtotal gastrectomy, followed by chemotherapy.
- Stage III: The treatment for stage III stomach cancer is usually surgery, such as gastrectomy or subtotal gastrectomy, followed by chemotherapy and radiation therapy.
- Stage IV: The treatment for stage IV stomach cancer is usually chemotherapy, targeted therapy, or immunotherapy, as the cancer has spread to other parts of the body.
Frequently Asked Questions (FAQ)
- What are the symptoms of stomach cancer?
The symptoms of stomach cancer may include abdominal pain, weight loss, nausea, vomiting, and difficulty swallowing. - How is stomach cancer diagnosed?
Stomach cancer is diagnosed using a combination of tests, including endoscopy, biopsy, and imaging tests such as CT scans and PET scans. - What are the risk factors for stomach cancer?
The risk factors for stomach cancer include family history, obesity, smoking, and infection with the bacteria Helicobacter pylori. - What is the prognosis for stomach cancer?
The prognosis for stomach cancer depends on the stage of the disease, with earlier stages having a better prognosis than later stages. - Can stomach cancer be prevented?
While there is no guaranteed way to prevent stomach cancer, a healthy diet, regular exercise, and avoidance of tobacco and excessive alcohol consumption can reduce the risk of developing the disease.
Conclusion
Stomach cancer is a serious disease that requires prompt and effective treatment. The treatment of stomach cancer typically involves a combination of surgery, chemotherapy, and radiation therapy. The choice of treatment depends on the stage of the disease, as well as the overall health of the patient. Early detection and diagnosis are critical in improving the chances of survival and reducing the risk of complications. It is essential to be aware of the symptoms of stomach cancer and to seek medical attention if they occur. By understanding the treatment options and risk factors for stomach cancer, patients can make informed decisions about their care and take steps to reduce their risk of developing the disease.
