Stomach Cancer Treatment | Apollo Cancer Centres

Endoscopic mucosal resection - Removing early-stage tumours from the stomach lining using endoscopy
Subtotal / Total Gastrectomy - Removing the portion of the stomach affected by cancer along with adjacent lymph nodes.
Surgery for very advanced tumours- While advanced stomach cancer may be incurable, surgery can be used to make you comfortable (palliative surgery). Removing part of the stomach may relieve symptoms of a growing tumour such as bleeding, obstruction and vomiting.

This treatment uses high-powered energy from sources such as X-rays to destroy cancer cells and shrink tumours. Doctors carefully direct the energy to the tumour, while sparing the surrounding healthy tissue.
In the case of stomach cancers, radiotherapy can be given postoperatively in high-risk cases to decrease the chances of recurrence. In cases of advanced cancer, radiation therapy may be used to relieve side effects caused by a large tumour.
High precision techniques like Intensity Modulated Radiotherapy (IMRT), Image guided Radiotherapy (IGRT), and Volumetric Modulated Arc therapy (VMAT/RapidArc) are useful in targeting the tumour accurately and avoiding normal tissue injury.

Chemotherapy is a drug treatment that uses chemicals to kill cancer cells. Chemotherapy drugs travel throughout the body, killing cancer cells that may have spread beyond the stomach.
Chemotherapy can be given before surgery (neoadjuvant chemotherapy) to help shrink a tumour so that it can be more easily removed. It is also used after surgery (adjuvant chemotherapy) to kill any cancer cells that might remain in the body. Chemotherapy may be used alone in people with advanced stomach cancer to help relieve signs and symptoms.
Targeted therapy uses drugs that attack specific abnormalities within cancer cells. Targeted drugs used to treat stomach cancer are decided based on the genetic makeup of the tumour tissue and are usually used in advanced cancer.
Targeted drugs are often used in combination with standard chemotherapy drugs.
Immunotherapy is a drug treatment that uses the immune system to fight cancer. The body's disease-fighting immune system may not attack cancer because the cancer cells produce proteins that blind the immune system cells from recognizing the cancer cells. Immunotherapy works by interfering with that process.
Immunotherapy is usually reserved for advanced stomach cancer and is given in combination with chemotherapy. The doctor might have your cancer cells tested to see if they're likely to respond to this treatment.
