Summary
A quality improvement initiative enhanced lymph node dissection adequacy in lung cancer surgery, improving disease-free survival. However, long-term outcomes depend more on disease burden and adjuvant therapies.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Quality Improvement in Healthcare
Background:
- Adequate lymph node (LN) dissection is crucial for accurate staging and treatment planning in non-small cell lung cancer (NSCLC).
- Quality improvement initiatives aim to standardize and enhance surgical procedures for better patient outcomes.
Purpose of the Study:
- To assess the impact of a quality improvement initiative on the adequacy of intraoperative lymph node dissection in NSCLC patients.
- To evaluate the relationship between nodal dissection quality metrics and long-term patient survival.
Main Methods:
- A retrospective review of 781 NSCLC patients with pathological lymph node involvement was conducted.
- Lymph node dissection quality metrics (QM1, QM2, QM3) were compared before and after initiative implementation.
- Cox proportional hazard regression analyzed the association between the initiative, quality metrics, and survival outcomes.
Main Results:
- The initiative significantly improved the achievement of QM2 (79.5% to 88.6%) and QM3 (76.2% to 84.4%).
- Patients operated on post-initiative showed improved disease-free survival (aHR: 0.73).
- Adjuvant chemotherapy (aHR: 0.55) and immunotherapy (HR: 0.54) were associated with improved survival, while quality metrics did not significantly influence long-term outcomes.
Conclusions:
- Transparent data and collaborative feedback effectively enhanced nodal assessment quality in lung cancer surgery.
- While the quality initiative improved dissection metrics and short-term survival, long-term outcomes are primarily driven by disease burden, adjuvant chemotherapy, and immunotherapy.
