Objective:

To compare long-term outcomes of radical surgical resection versus stereotactic body radiotherapy (SBRT) in patients with oligometastatic colorectal cancer, with a focus on overall survival (OS) as the primary endpoint and other relevant outcomes.

Key Findings:

• Radical surgical resection and SBRT showed differing long-term outcomes in overall survival, with implications for treatment selection.
• SBRT provided a non-invasive alternative with significant local control rates.
• Quality of life assessments indicated varying impacts between treatment modalities, suggesting the need for personalized approaches.

Interpretation:

The study provides valuable insights into the comparative effectiveness of surgical resection versus SBRT in oligometastatic colorectal cancer, emphasizing the importance of personalized treatment approaches based on patient characteristics and preferences.

Limitations:

• Non-randomized design may introduce selection bias despite propensity score matching, potentially affecting the reliability of outcomes.
• Limited generalizability due to specific eligibility criteria, which may not reflect the broader patient population.
• Potential confounding factors not fully accounted for in observational study design, impacting the interpretation of results.

Conclusion:

This study underscores the importance of individualized treatment strategies in oligometastatic colorectal cancer, advocating for further research to refine therapeutic approaches.
