Short answer · Medically reviewed summary · Last updated: 2026-05-08
The primary treatments for stomach cancer, or gastric cancer, are typically determined by the stage of the disease and include surgical resection, chemotherapy, radiation therapy, and targeted immunotherapy. Because stomach cancer is highly heterogeneous, treatment plans must be personalized by a multidisciplinary oncology team to address the specific tumor biology and the patient's overall health. What are the primary treatment modalities for stomach cancer? Treatment for stomach cancer often involves a combination of therapies.

Treatments for Stomach cancer: what real patients say works for them, alongside a medically reviewed overview citing sources like NIH GARD and Orphanet.
The primary treatments for stomach cancer, or gastric cancer, are typically determined by the stage of the disease and include surgical resection, chemotherapy, radiation therapy, and targeted immunotherapy. Because stomach cancer is highly heterogeneous, treatment plans must be personalized by a multidisciplinary oncology team to address the specific tumor biology and the patient's overall health.
What are the primary treatment modalities for stomach cancer?
Treatment for stomach cancer often involves a combination of therapies. Surgery to remove part or all of the stomach (gastrectomy) remains the only curative option for localized stomach cancer. This is frequently combined with perioperative chemotherapy (before and after surgery) to improve survival rates. For advanced or metastatic stomach cancer, systemic therapies are the standard of care.
Which medications and targeted therapies are used?
Systemic treatment for stomach cancer has evolved to include targeted agents alongside traditional cytotoxic chemotherapy. Common approaches include:
- Chemotherapy: Common regimens include fluorouracil (5-FU), capecitabine (Xeloda), oxaliplatin (Eloxatin), and docetaxel (Taxotere).
- Targeted Therapy: Trastuzumab (Herceptin) is used for HER2-positive stomach cancer, while ramucirumab (Cyramza) may be used to inhibit tumor blood vessel growth.
- Immunotherapy: Pembrolizumab (Keytruda) is increasingly utilized for patients with specific biomarkers like MSI-H or high PD-L1 expression.
Which specialists should be on the care team?
Managing stomach cancer requires a multidisciplinary team to ensure comprehensive care. Essential specialists include a surgical oncologist, a medical oncologist, a radiation oncologist, a gastroenterologist, and a registered dietitian specializing in oncology to manage the significant nutritional challenges associated with gastric surgery.
What is the role of emerging research?
Clinical trials are actively investigating novel combinations, including antibody-drug conjugates and advanced CAR-T cell therapies for stomach cancer. Participation in clinical trials can provide access to cutting-edge treatments that are not yet available as standard care.
