Summary
Achieving complete resection margins in lung cancer surgery significantly improves patient survival. Intraoperative frozen section analysis is crucial for verifying clear margins and guiding further resection if residual tumor is detected.
Area of Science:
- Thoracic surgery
- Surgical oncology
- Pulmonary medicine
Context:
- Lung cancer resection with standard lymph node dissection.
- Residual tumor (R1) identified at the proximal bronchial resection margin in 3.6% of cases.
- Significant difference in outcomes based on resection completeness.
Purpose:
- To evaluate the impact of residual tumor at the bronchial resection margin on lung cancer patient outcomes.
- To determine the necessity of intraoperative frozen section analysis for verifying resection margins.
- To assess the influence of tumor stage, histology, and postoperative radiation on survival after incomplete resection.
Summary:
- Incomplete resection (R1) in lung cancer surgery was associated with a median survival of 16 months, compared to 37 months for complete resection (P < 0.001).
- Postoperative complications included bronchial fistula, bleeding, and heart luxation, with a 16.6% in-hospital mortality rate.
- Survival length was not significantly affected by tumor stage, histology, infiltration site, or postoperative radiation therapy.
Impact:
- Intraoperative frozen section analysis is recommended to ensure clear bronchial resection margins during lung cancer surgery.
- Wider resection is indicated for residual tumor in Stage I and II lung cancer patients meeting functional criteria.
- Complete resection offers a better prognosis than R1-resection across all stages, particularly in earlier stages of lung cancer.
