About

Gastric cancer (GC) is one of the most common and lethal cancers worldwide, especially in China, and the median overall survival for patients with advanced, metastatic GC remains only about 1 year. Several molecular profiling studies have demonstrated that a proportion of gastric cancer harbour actionable molecular alterations which shows a predictive benefit from a specific therapy (in any cancer type). In the current study, the efficacy of precision treatment for gastric cancer guided by multidimensional molecular biology profiling will be observed. The analysis focused on the overall survival outcomes for patients whose tumours harboured actionable molecular alterations and who received appropriately matched therapy.

Trial design

1,000 participants in 3 patient groups

Matched therapy

Description:

Molecular profiling performed with actionable molecular alterations detected and target therapy was then conducted

Unmatched therapy

Description:

Molecular profiling performed with actionable molecular alterations detected but therapy was conducted based on the guideline treatment

No marker

Description:

Molecular profiling performed without any actionable molecular alterations detected, tranditional therapy based on the guideline was then conducted
