Comparison of Surgical Approaches for Right Colon Cancer in 290 Patients

This retrospective study analyzes clinical data from 290 patients who underwent laparoscopic right hemicolectomies for colon cancer, comparing medial and mixed surgical approaches. It reports 3-year disease-free survival and overall survival outcomes, with patients categorized into a medial approach group (n=144) or a mixed approach group (n=146).

Use Cases

• Compare 3-year disease-free survival (DFS) rates between the medial approach and mixed approach patient groups.
• Analyze overall survival (OS) outcomes relative to surgical approach and tumor stage.
• Investigate tumor location and chemotherapy completion as independent prognostic factors for DFS.
• Perform propensity score matching based on six key variables to compare outcomes between the two surgical groups.

Strengths

• Data from 290 patient records provides a basis for comparing two surgical cohorts.
• Study reports specific hazard ratios and confidence intervals for DFS and OS outcomes.
• Analysis includes propensity score matching based on six key variables to minimize confounding.

Limitations

• Small sample size of 290 patients limits statistical power for detecting subtle differences in survival outcomes.
• Single-institution retrospective study design may introduce selection bias and limit generalizability.
• Data is presented in a DOCX document, requiring extraction for computational analysis; underlying tabular data structure is unknown.
