Gastric Cancer Survivor Study on Residual Gastric Volume and Sleep Disturbance

Longxin Fan's 2026 study investigates the association between residual gastric volume and long-term postoperative sleep disturbances in gastric cancer survivors. The dataset includes 412 patients who underwent partial gastrectomy, with data on demographics, tumor features, treatment, complications, diet, and physical activity collected via interviews and medical records. Sleep quality was assessed using the Pittsburgh Sleep Quality Index at 6, 9, and 12 months postoperatively.

Use Cases

• Predicting long-term sleep disturbance risk based on residual gastric volume and patient characteristics.
• Analyzing the relationship between postoperative complications and patient-reported sleep quality scores.
• Modeling the impact of dietary habits and physical activity on recovery outcomes after gastrectomy.
• Identifying high-risk patient subgroups for targeted clinical interventions based on multivariate logistic regression results.

Strengths

• Includes 412 patient records, providing a substantive cohort for analysis.
• Longitudinal sleep quality assessment at three time points (6, 9, and 12 months) using the validated PSQI instrument.
• Multivariate analysis was performed, adjusting for potential confounding factors mentioned in the description.

Limitations

• Row count for the underlying data is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (48.4 KB), indicating limited scope or summary-level data.
