Stomach Cancer Stage IA

What Stage IA Means

Small tumor limited to innermost stomach lining (T1) with no lymph node involvement (N0). No distant metastases.

Treatment Approach for Stage IA

Endoscopic resection for very small lesions, or partial gastrectomy with D2 lymph node dissection. Adjuvant chemotherapy not routinely needed but may be considered for higher-risk features.

Survival Rates and Prognosis

The 5-year survival rate for stomach cancer at Stage IA is approximately 5-year survival approximately 70–75%. Survival rates are statistical averages drawn from large patient populations and may not reflect your individual outcome. Factors that influence your specific prognosis include your age, overall health, tumour biology, and how well the cancer responds to treatment.

Important: These numbers are drawn from historical data. Newer treatments available today may improve outcomes beyond what published statistics show. Discuss your individual prognosis with your oncologist.
