Minimal Data Set: Gastric Cancer Survival from a Phase II Clinical Trial

Between 2017 and 2021, 13 patients from 2 institutions were enrolled in a single-arm, multi-institutional exploratory Phase II trial. The dataset likely contains results assessing the effect of extensive intraoperative peritoneal lavage on relapse-free and overall survival for gastric cancer patients with positive cytology. The data was authored by Gen Tsujio and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Analyze relapse-free survival (RFS) outcomes based on cytology status mentioned in the description
• Compare overall survival (OS) and peritoneal recurrence rates between patient subgroups
• Study the relationship between intraoperative cytology results and postoperative recurrence sites
• Evaluate the incidence of postoperative adverse events in a specific surgical cohort

Strengths

• Data originates from a structured, multi-institutional Phase II clinical trial.
• Includes specific survival metrics like median 3-year RFS (14.5 months) and peritoneal RFS (16.0 months).
• Provides a clear patient cohort breakdown (n=6 for CY0/stamp+, n=7 for CY1).

Limitations

• The trial was closed early with only 13 patients, limiting statistical power.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
