Comparison of Surgical Approaches for Colon Cancer in 290 Patients

Clinical data from 290 patients who underwent laparoscopic right hemicolectomies for colon cancer, comparing medial and mixed surgical approaches. The study analyzed 3-year disease-free survival (DFS) and overall survival (OS) outcomes, with patients categorized into two groups of 144 and 146. Propensity score matching was performed based on six key variables to minimize confounding.

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 tumor location and chemotherapy completion status.
• Investigate the relationship between surgical approach and hazard ratios (HR) for DFS and OS across tumor stages.
• Perform propensity score matching analysis using the six key baseline variables to assess treatment effects.

Strengths

• Clinical data from 290 patients provides a basis for comparative analysis.
• Study design includes propensity score matching based on six key variables to control for confounding.
• Explicit endpoints of 3-year disease-free survival and overall survival are defined.

Limitations

• Small sample size of 290 patients limits statistical power for subgroup analyses.
• Retrospective, single-institution study design may introduce selection bias.
• Specific column names and raw data values are not provided in the description.
