What are the treatment methods for Stomach (Gastric) Cancer?
There are different methods of treatment of stomach cancer (gastric cancer) which the doctor may advise. The type of treatment best suitable for you is decided keeping in mind certain factors such as the period of time you have had the cancer, the extent of damage caused by the cancer and what is the stage (development) of the cancer.
These are the various types of treatment that are used to cure and/or prevent the chances of the cancer recurring:
- Surgery – This is the most effective form of treating stomach (gastric) cancer. The latest in surgical treatment for stomach cancer is known as the ‘endoscopic mucosal resection’ (EMR) which is a minimally invasive surgical technique. In this procedure the tumor and the mucosa (inner stomach lining) is removed (resection) from the stomach using an instrument known as an ‘electrical wire loop’. Another variant of this minimally invasive surgery is known as the ‘endoscopic sub-mucosal dissection’ (ESD) which requires removing a larger area of the inner stomach lining (mucosa) in one go.
- Chemotherapy – Chemotherapy has been more successful in palliative care of stomach cancer (in reducing the size of tumor, relieve symptoms and raise the chances of survival) than its complete treatment. A combination of drugs and medicines are used in chemotherapy of the stomach cancer such as 5-FU (fluorouracil), BCNU (carmustine), methyl-CCNU (semustine), doxorubicin (Adriamycin), mitomycin C as well as trastuzumab for targeted treatment.
- Radiation therapy – Radiation therapy is used in combination with surgery and chemotherapy to treat stomach cancer.
