Gastric Cancer Market to Grow at a CAGR of 12.63% During 2026-2035, Aided by the Growth in Clinical Trials Across the 8 Major Markets

Gastric Cancer Market Overview

Gastric cancer or stomach cancer originates in the cells that line the stomach. Targeted therapies and chemotherapy are commonly recommended for the treatment of this cancer. The growing aging population and lifestyle-related factors including dietary habits and smoking are contributing to the rise in the cases of gastric cancer. The rising development of targeted therapies and immunotherapy such as pembrolizumab (Keytruda) and nivolumab (Opdivo) are expected to bolster the market growth. Moreover, the expansion of clinical trials for novel drugs and combination therapies is likely to shape the market landscape in the forecast period.

Key Findings

• Treatment is shifting from chemotherapy alone to immunotherapy and targeted combinations, with first-line immunotherapy-plus-chemotherapy regimens, HER2-directed antibody-drug conjugates, and, most recently, perioperative immunotherapy reaching patients with early-stage disease.
• New molecular targets are expanding precision treatment, with Claudin 18.2 and FGFR2b emerging as actionable biomarkers in gastric cancer, adding to established HER2 and PD-L1 testing to guide therapy selection.
• Early detection and biomarker testing are increasingly central, as HER2, PD-L1, microsatellite instability, and Claudin 18.2 status now shape treatment decisions and support the move toward personalised gastric cancer care.

Gastric Cancer Market Demand Drivers

Gastric cancer ranks as the second most common cause of cancer death worldwide, reflecting the need for effective treatments to combat the disease. In India, gastric cancer is reported as the fifth most common cancer in men while in women, it is the seventh most common cancer. The prevalence of gastric cancer is high in East Asian countries such as Japan where it causes significant mortality. For instance, in 2022, around 41,000 deaths occurred in Japan due to gastric cancer. Thus, the substantial burden of gastric cancer is driving the market demand for advanced therapies and diagnostics.

Gastric Cancer Market Segmentation Analysis

The Treatment Type Segment is Poised to Experience Significant Market Growth

Based on type, the market segmentation includes chemotherapy, immunotherapy, surgery, targeted drug therapy, and others. The surgery segment holds a high market value as it is one of the most effective treatments for early-stage gastric cancer. Surgery is a common treatment for localized gastric cancer and the advancements in minimally invasive procedures such as laparoscopic and robotic surgeries are further propelling the market growth. Additionally, the rising preference for the combination of surgery with other treatments like chemotherapy and radiation is poised to boost the demand for the segment.

The market report also offers insights based on cancer type, route of administration, end user, and region.

Gastric Cancer Market: Competitive Landscape

• In November 2025, AstraZeneca received FDA approval for Imfinzi (durvalumab) plus FLOT chemotherapy as the first and only perioperative immunotherapy for resectable, early-stage and locally advanced gastric and gastroesophageal junction cancers, followed by EU approval in March 2026, based on the MATTERHORN Phase 3 trial, which showed a 22% reduction in the risk of death, with nearly 7 in 10 patients alive at three years. AstraZeneca also markets Enhertu (trastuzumab deruxtecan), a HER2-directed antibody-drug conjugate for HER2-positive advanced gastric cancer, developed with Daiichi Sankyo.
• Amgen and Eli Lilly are advancing targeted approaches, with Amgen developing bemarituzumab, an FGFR2b-directed therapy in late-stage trials for gastric cancer, and Eli Lilly marketing Cyramza (ramucirumab), a VEGFR2 inhibitor used in advanced gastric cancer.
• Other players include Pfizer, Bristol-Myers Squibb Company, Novartis, Celltrion, AbbVie, and GSK, spanning targeted therapies, immunotherapies, and biosimilar antibodies across gastric cancer care.
