This prospective, multi-center, non-interventional study will evaluate the efficacy and safety of Herceptin (trastuzumab) in routine clinical practice in Chinese patients with gastric or gastro-oesophageal cancer. Treatment patterns and clinical outcomes in patients with gastric cancer in China will be evaluated. Data will be collected from eligible patients for up to 6 years.

Primary Outcome Measures:
  • Overall survival, defined as time from date of diagnosis of gastric cancer to death of any cause [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Response rate (RR), defined as proportion of patients with complete response (CR) or partial response (PR) based on their best overall response assessed by investigator [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Cohort I/II/IV: Time to treatment failure (TTF), defined as time from start of treatment in each line (1st, 2nd, 3rd line) to investigator-assessed disease progression in each line, or death of any cause [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Cohort I/II/V Progression-free survival (PFS) defined as time from treatment in each line (1st, 2nd, 3rd line) to investigator assessed progression or death from any cause [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Cohort III/V: Event-free survival (EFS), defined as time from date of diagnosis of gastric cancer to disease recurrence or progression, or death from any cause [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Cohort III/V: Disease-free survival (DFS), defined as time from R0 resection to investigator-assessed disease progression, or death of any cause [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety: Incidence of adverse events in patients receiving Herceptin [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
  • Treatment regimens (drugs, dosage, duration) in routine clinical practice [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
