Poor Karnofsky performance status is not a contraindication for neurosurgical resection in patients with lung cancer brain metastases: a multicenter, retrospective PSM-IPTW cohort study
To determine whether neurosurgical resection provides a significant survival benefit in patients with lung cancer brain metastases and poor Karnofsky performance status (KPS).
Key Findings:
Surgical resection in patients with poor KPS (≤ 70) was associated with improved overall survival (OS).
Multivariate analysis indicated that pretreatment KPS ≤ 70 correlated with poorer outcomes (HR: 1.71, 95% CI: 1.47–2.00, P < 0.001).
The study suggests that poor KPS should not exclude patients from surgical consideration, highlighting the need for reevaluation of surgical candidacy criteria.
Interpretation:
The findings challenge the traditional exclusion of patients with poor KPS from surgical interventions, indicating potential survival benefits from neurosurgical resection.
Limitations:
The retrospective design may introduce selection bias, potentially affecting the reliability of the results.
The study's single-region focus limits the generalizability of the findings to broader populations.
Potential confounding factors were not fully controlled, which may influence the observed outcomes.
Conclusion:
Neurosurgical resection may be beneficial for patients with lung cancer brain metastases and poor KPS, warranting a reconsideration of surgical candidacy criteria and further research to validate these findings.
