Stomach (Gastric) Cancer Treatment in India for International Patients 2026
Stomach cancer — also called gastric cancer — is the fifth most common cancer globally and remains a significant cause of cancer-related mortality across Africa and other developing regions, partly because it is frequently diagnosed at an advanced stage when treatment is more complex. For patients and families facing this diagnosis, accessing high-quality oncology care is urgent. India's leading cancer hospitals offer the full spectrum of gastric cancer treatment — surgery, chemotherapy, targeted therapy, immunotherapy, and radiation — at a fraction of the cost of treatment in the UK or United States.
TL;DR: Stomach cancer treatment in India costs $8,000–35,000 depending on stage, treatment approach, and duration. Early-stage gastrectomy (surgery alone) is $8,000–15,000. Combined multimodal treatment for advanced stages runs $20,000–35,000. These figures represent 60–75% savings over US and UK costs. India's oncology centres have specialist gastric cancer teams, robotic surgery, and multidisciplinary tumour boards that individualise treatment for every patient.
This guide covers everything you need to know about gastric cancer treatment in India — staging, surgical options, chemotherapy, targeted therapy, top hospitals, costs, and how to plan your treatment journey from abroad.
Understanding Stomach (Gastric) Cancer
Gastric cancer develops in the lining of the stomach (gastric mucosa). It most commonly arises from glandular cells in the stomach lining (adenocarcinoma accounts for approximately 90–95% of all stomach cancers). Other, rarer types include gastric lymphoma, gastrointestinal stromal tumours (GIST), and carcinoid tumours — each requiring different treatment approaches.
Risk Factors
- Helicobacter pylori (H. pylori) infection: The single most important modifiable risk factor for gastric adenocarcinoma
- Diet: High salt, pickled, and smoked foods; low fruit and vegetable consumption
- Tobacco and alcohol use
- Family history of gastric cancer or hereditary syndromes (e.g. CDH1 mutations causing hereditary diffuse gastric cancer)
- Previous stomach surgery or chronic atrophic gastritis
- Male sex and age over 50
Symptoms That Lead to Diagnosis
Early gastric cancer often causes no symptoms, which is why most patients present at a more advanced stage. Common presenting symptoms include:
- Persistent upper abdominal pain or discomfort
- Unintentional weight loss
- Loss of appetite (anorexia)
- Nausea, vomiting, or early satiety
- Dark stools or vomiting blood (signs of bleeding)
- Jaundice (if cancer involves the pylorus or spreads to the liver)
- Difficulty swallowing (for cancers near the gastro-oesophageal junction)
Any persistent upper GI symptoms in a patient over 45, or at any age with a family history of gastric cancer, warrant urgent upper endoscopy.
Staging Gastric Cancer: Why It Determines Treatment
Gastric cancer staging uses the TNM system:
- T (Tumour): Depth of tumour invasion into the stomach wall (T1 = superficial, T4 = invades adjacent structures)
- N (Nodes): Regional lymph node involvement (N0 = none, N3 = ≥15 nodes)
- M (Metastasis): Spread to distant organs (M0 = no metastasis, M1 = distant spread)
| Stage | Description | Primary Treatment |
|---|---|---|
| Stage I (T1–2, N0–1, M0) | Early localised | Surgery alone (gastrectomy) |
| Stage II (T1–3, N0–2, M0) | Locally advanced | Surgery + perioperative chemotherapy |
| Stage III (T2–4, N1–3, M0) | Regionally advanced | Surgery + perioperative or adjuvant chemo ± radiation |
| Stage IV (any T, any N, M1) | Metastatic | Systemic chemotherapy, targeted therapy, immunotherapy; surgery rarely curative |
Accurate staging before treatment begins is essential. In India, this typically involves upper GI endoscopy with biopsy, CT scan of chest/abdomen/pelvis, endoscopic ultrasound (EUS) for T and N staging, and PET-CT in selected cases.
Surgical Treatment for Gastric Cancer in India
Surgery remains the only curative treatment for non-metastatic gastric cancer. The extent of surgery depends on tumour location and stage.
Types of Gastrectomy
Distal gastrectomy (partial gastrectomy): Removal of the lower two-thirds of the stomach, used for cancers of the antrum or body. The remaining stomach is connected to the small intestine (gastrojejunostomy or Billroth reconstruction). Preferred when the cancer is located away from the gastro-oesophageal junction.
Total gastrectomy: Removal of the entire stomach, with the oesophagus connected directly to the small intestine (oesophagojejunostomy, Roux-en-Y). Required for cancers of the upper stomach or those that are multifocal. Nutritional consequences are more significant — vitamin B12 and iron supplementation is lifelong.
Proximal gastrectomy: Removal of the upper stomach, used selectively for early-stage cancers at the gastro-oesophageal junction. Less radical than total gastrectomy, with preserved distal stomach function.
D2 Lymphadenectomy: Standard of care for curative-intent gastric cancer surgery in India. The surgeon removes at least 15 regional lymph nodes along defined anatomical stations. D2 dissection improves staging accuracy and may improve survival compared to more limited D1 dissection.
Robotic-Assisted Gastrectomy
Robotic surgery using the Da Vinci system is available at Apollo Hospitals, Max Healthcare, Medanta, Kokilaben Hospital, and Manipal Hospitals in India. Robotic gastrectomy offers:
- Improved precision for D2 lymph node dissection in the confined gastric anatomical space
- Smaller incisions and reduced blood loss compared to open surgery
- Faster post-operative recovery
- Comparable oncological outcomes to open gastrectomy at experienced centres
Cost premium over conventional laparoscopic gastrectomy: approximately $2,000–4,000. Your surgeon will advise on suitability based on tumour stage, location, and anatomy.
Cost of Gastrectomy in India
| Procedure | India Cost | US Cost | UK Private Cost |
|---|---|---|---|
| Distal gastrectomy (laparoscopic) | $8,000–12,000 | $40,000–80,000 | $25,000–45,000 |
| Total gastrectomy (open or laparoscopic) | $10,000–16,000 | $50,000–100,000 | $30,000–55,000 |
| Robotic gastrectomy | $12,000–20,000 | $60,000–110,000 | $35,000–60,000 |
Chemotherapy for Gastric Cancer in India
Chemotherapy is used in three settings for gastric cancer:
Perioperative chemotherapy (before and after surgery): The most common approach for Stage II–III gastric cancer in India. Based on the FLOT regimen (fluorouracil, leucovorin, oxaliplatin, docetaxel) or FOLFOX. Four cycles before surgery, four cycles after surgery. Aim is to downstage the tumour and reduce the risk of recurrence.
Adjuvant chemotherapy (after surgery alone): Used when surgery was performed without pre-operative chemotherapy. Based on XELOX (capecitabine + oxaliplatin) or S-1 + oxaliplatin depending on the institution and patient factors.
Palliative chemotherapy (for Stage IV or unresectable disease): Chemotherapy extends survival and maintains quality of life. First-line regimens include FOLFOX, XELOX, or fluorouracil + cisplatin. Second-line options include taxane-based regimens.
Cost of Chemotherapy in India
Each chemotherapy cycle typically costs $600–1,800 in India depending on the regimen. A full perioperative course (eight cycles total) costs $5,000–14,000. This is inclusive of drug costs, day-care admission, nursing, anti-emetics, and supportive medicines. In the US, a single cycle of FLOT can cost $8,000–15,000.

Targeted Therapy and Immunotherapy in India
HER2-Positive Gastric Cancer
Approximately 15–20% of gastric adenocarcinomas overexpress the HER2 protein. Testing for HER2 (by immunohistochemistry and FISH on biopsy tissue) is now standard. HER2-positive patients with metastatic disease receive trastuzumab (Herceptin) added to chemotherapy as first-line treatment — the ToGA regimen. Trastuzumab biosimilars are widely available in India at significantly lower cost than originator biologics.
Immunotherapy (Checkpoint Inhibitors)
PD-L1 testing and MSI (microsatellite instability) status now guide the use of immune checkpoint inhibitors in gastric cancer:
- Pembrolizumab (Keytruda): Approved for PD-L1-positive or MSI-high gastric cancer in the first and later lines. Available at major Indian oncology centres with biosimilar alternatives emerging.
- Nivolumab (Opdivo): Used in combination with chemotherapy for advanced HER2-negative gastric cancer in the first line based on CheckMate-649 data.
Cost of immunotherapy in India is lower than in Western markets due to biosimilar availability and compassionate programmes, but remains significant — typically $2,000–5,000 per month per patient depending on the agent.
Radiation Therapy for Gastric Cancer in India
Radiation has a more limited role in gastric cancer compared to other GI cancers. It is used in specific scenarios:
Chemoradiation after surgery: For patients who did not receive perioperative chemotherapy and have high-risk pathological features (positive margins, extensive node involvement). The INT-0116 regimen (fluorouracil-based chemoradiation) is used.
Palliative radiation: For symptom control — reducing bleeding from the tumour, relieving pain from local invasion, or managing bone metastases.
India's leading cancer centres have modern radiotherapy capabilities including IMRT (intensity-modulated radiation therapy), IGRT (image-guided radiotherapy), and stereotactic body radiotherapy (SBRT) for metastases. For an overview of radiation oncology in India, see our radiation oncology guide.

Diagnostic Workup in India: What to Expect on Arrival
If you arrive in India with a new or recently made gastric cancer diagnosis, the hospital will typically complete the following within two to three days of arrival:
- Upper GI endoscopy with biopsy (if not recently performed or if prior biopsy slides need re-review by Indian pathologist)
- CT scan of chest, abdomen, and pelvis (staging)
- Endoscopic ultrasound (EUS) for T and N staging — particularly important for determining resectability
- PET-CT scan (selected cases where distant metastasis needs exclusion)
- HER2 testing and MSI/dMMR testing on biopsy tissue (guides targeted therapy eligibility)
- Blood tests: CBC, liver function, kidney function, CEA, CA 19-9, albumin, coagulation
Bring all your existing reports and imaging with you — on CD/USB for DICOM scans. This avoids repeating investigations unnecessarily and reduces your pre-treatment workup time.
Planning Your Treatment Journey to India
Sharing Your Records in Advance
Before travelling, share your endoscopy and biopsy reports, CT or MRI scans, blood tests, and pathology reports with your chosen hospital or facilitator. A GI oncologist reviews your case and advises on whether further staging workup is needed and what the likely treatment plan will be. This avoids delays once you arrive.
Typical Timeline for Gastric Cancer Patients
Week 1: Arrival, staging investigations, multidisciplinary tumour board review, treatment plan discussed and agreed
Weeks 2–8: Pre-operative chemotherapy (if perioperative approach), day-case chemo sessions
Surgery: Typically week 9–10 after completing pre-operative chemo cycles
Recovery: 10–14 days in hospital, 1–2 weeks recovery before flying home
Post-operative chemo: Cycles can partly be administered in home country or back in India on return visits
How Long Will You Need to Stay in India?
- Surgery alone (early stage): Three to four weeks (pre-operative assessment + surgery + recovery)
- Perioperative chemotherapy + surgery: Eight to twelve weeks for the full perioperative course in India
- Palliative chemotherapy (Stage IV): Many patients return for two to three cycles and then continue at home or via telemedicine follow-up
Your oncologist will design a treatment schedule that minimises your time in India while ensuring clinical safety. Some chemotherapy cycles can be administered in your home country if your local oncologist is willing to coordinate — India provides the planning, surgery, and complex assessments.
What to Bring
- All medical records and imaging on CD/USB
- List of current medications
- Contact details of your home-country oncologist or specialist
- Medical power of attorney document if travelling with a family member who may need to make decisions on your behalf
- Comfortable loose clothing (especially important post-gastrectomy when eating small frequent meals)
- A notebook or health journal for tracking symptoms, meals, and questions for your oncology team

Nutrition After Gastric Cancer Surgery
Nutritional management is a critical part of recovery after gastrectomy. The stomach's capacity is reduced (partial) or eliminated (total), significantly affecting eating habits:
Immediately after surgery: Clear liquids progressing to soft foods over the first two weeks. The hospital dietitian will provide a structured meal plan.
First three months: Small, frequent meals (six to eight per day) of soft, easily digestible foods. Avoid high-sugar foods (risk of dumping syndrome — rapid gastric emptying causing sweating, palpitations, and diarrhoea after sweet foods). Separate liquids from solid food at meals.
Long-term supplements (especially after total gastrectomy):
- Vitamin B12 injections (monthly, lifelong — the stomach produces intrinsic factor required for B12 absorption, which is eliminated after total gastrectomy)
- Iron supplementation (non-haem iron absorption is reduced)
- Calcium and Vitamin D
- Fat-soluble vitamins (A, D, E, K) if fat absorption is affected
Most patients achieve a reasonable quality of life with dietary adjustment within three to six months of surgery. Working with a dietitian experienced in post-gastrectomy nutrition — available at all major Indian oncology centres — is strongly recommended.
