Gastric cancer, also known as stomach cancer, is a type of cancer that originates in the lining of the stomach. It is the fifth most common cancer worldwide and the third leading cause of cancer-related deaths. The treatment of gastric cancer depends on the stage and location of the tumor, as well as the patient’s overall health and medical history. Below is detailed information about gastric cancer therapeutics.
- Surgery: Surgery is the primary treatment for gastric cancer. It involves removing all or part of the stomach and nearby lymph nodes. The type of surgery performed depends on the location and stage of the tumor.
- Chemotherapy: Chemotherapy is the use of drugs to destroy cancer cells. It is often used in combination with surgery to treat gastric cancer. Chemotherapy may be given before surgery (neoadjuvant chemotherapy) to shrink the tumor and make it easier to remove or after surgery (adjuvant chemotherapy) to kill any remaining cancer cells.
- Radiation therapy: Radiation therapy uses high-energy radiation to kill cancer cells. It is often used in combination with chemotherapy to treat advanced gastric cancer or to relieve symptoms such as pain or bleeding.
- Targeted therapy: Targeted therapy is a type of cancer treatment that targets specific proteins or genes that contribute to the growth and spread of cancer cells. Trastuzumab is a targeted therapy drug that is used to treat HER2-positive gastric cancer.
- Immunotherapy: Immunotherapy is a type of cancer treatment that helps the immune system to recognize and destroy cancer cells. Nivolumab and Pembrolizumab are two immunotherapy drugs that have been approved for the treatment of advanced gastric cancer.
- Palliative care: Palliative care focuses on relieving the symptoms and improving the quality of life of patients with advanced gastric cancer. It includes treatments such as pain management, nutritional support, and emotional support.
- Clinical trials: Clinical trials are research studies that test new treatments for gastric cancer. They may offer patients the opportunity to receive new treatments before they are widely available.
In conclusion, the treatment of gastric cancer is complex and often involves a combination of therapies. The choice of therapy depends on the stage and location of the tumor, as well as the patient’s overall health and medical history. It is important for patients to work closely with their healthcare team to determine the best treatment plan for their individual needs.
