Best Hospitals for Stomach Cancer Treatment in Bengaluru, India

Gastric cancer arises predominantly from the glandular epithelium of the stomach lining (adenocarcinoma in ~95% of cases) and is further classified by anatomic location (cardia/gastro-esophageal junction vs. body vs. antrum/pylorus), Lauren histological subtype (intestinal, diffuse, or mixed), and molecular subtype per The Cancer Genome Atlas (TCGA) classification—Epstein-Barr virus-positive, microsatellite instable (MSI-H), chromosomally instable (CIN), and genomically stable (GS). Helicobacter pylori infection, atrophic gastritis, intestinal metaplasia, smoking, high-salt diets, and hereditary diffuse gastric cancer (CDH1 germline mutations) are the principal etiological drivers. Physiologically, tumor growth disrupts gastric acid secretion, impairs digestion, and commonly causes protein-calorie malnutrition; advanced disease may obstruct the gastric outlet or invade adjacent structures (pancreas, transverse colon, liver), producing ascites, peritoneal carcinomatosis, or hepatic metastases.

• ELIGIBLE FOR CURATIVE SURGICAL RESECTION:
• Clinical stage IA–IIIC (cT1–T4a, N0–N3, M0) confirmed by EUS, CT, PET-CT, and diagnostic laparoscopy
• Adequate cardiopulmonary reserve: ECOG performance status 0–2; left ventricular ejection fraction ≥50% (required before anthracycline-based chemotherapy); FEV1 ≥1.0 L for total gastrectomy candidates
• Nutritional optimization achievable: albumin >3.0 g/dL or correctable with pre-operative enteral nutrition; BMI considerations reviewed by bariatric-oncology team
• Absence of peritoneal carcinomatosis on diagnostic laparoscopy with negative peritoneal cytology

Surgical APPROACHES:

1. Distal (Subtotal) Gastrectomy with D2 Lymphadenectomy:

Indicated for tumors of the antrum and pylorus (lower two-thirds of the stomach). At least 4–5 cm proximal margin from the tumor is required. Reconstruction is performed via Billroth II (gastrojejunostomy) or Roux-en-Y configuration to prevent bile reflux. D2 dissection removes lymph node stations 1–12 as defined by the Japanese Gastric Cancer Association (JGCA), and retrieval of a minimum of 16 lymph nodes is required for accurate N-staging. D2 lymphadenectomy is the global standard and is associated with superior disease-specific survival compared to D1 in high-volume centers.

2. Total Gastrectomy with D2 Lymphadenectomy:

PHASE 1 — PRE-ARRIVAL PREPARATION (Weeks 1–3 before travel):

• GAF Healthcare coordinator collects existing pathology reports, imaging (CT/PET-CT DICOM files), endoscopy reports, and blood work and submits to the designated oncology team for remote multidisciplinary tumor board review.
• A written second-opinion report and individualized treatment plan (surgical vs. chemotherapy-first vs. palliative) is issued within 5–7 business days.
• Visa assistance initiated: e-Medical visa (India) processed in 3–5 business days; UAE entry visa or visa-on-arrival arranged as applicable.
• Nutritional prehabilitation initiated: patients with albumin <3.0 g/dL begin enteral or high-protein oral supplementation; smoking cessation mandatory.
• FLOT pre-operative chemotherapy (if applicable) may begin at the patient's home country after protocol review, or at the partner center after arrival.

PHASE 2 — ARRIVAL & STAGING CONFIRMATION (Days 1–4 in country):
