eCura Median Schedule: Risk Scores for Gastric Cancer Surgery Decisions

A retrospective case-control study of 290 patients with early gastric cancer who underwent endoscopic submucosal dissection (ESD) at Fujian Provincial Hospital between January 2011 and July 2024. The dataset, authored by Yangyang Chen, compares the w-eCura and eCura systems for predicting the need for salvage surgery after non-radical ESD.

Use Cases

• Comparing predictive performance of risk models (w-eCura vs. eCura) based on AUC metrics mentioned in the description
• Identifying clinicopathological factors influencing cancer residue status based on variables like invasion depth and margin status
• Conducting survival analysis for gastric cancer patients based on risk grades and monitored recurrence data
• Training models to predict the necessity of salvage surgery based on patient characteristics and procedure outcomes

Strengths

• Includes data from 290 patients, providing a substantive sample for analysis
• Covers a median follow-up duration of 32 months (range 15–54 months), offering longitudinal outcome tracking
• Compares two established risk stratification systems with quantified performance metrics (AUC of 0.82 vs. 0.79)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale modeling
• Data may reflect geographic bias inherent to the single-hospital (Fujian Provincial Hospital) source
