Summary
CT-guided localization before extended segmentectomy is effective for early-stage lung cancer. This approach preserves lung volume while achieving safe tumor removal and good patient outcomes.
Area of Science:
- Thoracic Surgery
- Oncology
- Diagnostic Imaging
Background:
- Lung cancer remains a significant global health challenge.
- Early detection via low-dose computed tomography (LDCT) enables timely intervention.
- Minimally invasive video-assisted thoracoscopic surgery is optimal for early-stage disease.
Purpose of the Study:
- To evaluate CT-guided localization for extended segmentectomy in deep or marginal lung tumors.
- To assess the safety and efficacy of this technique for early-stage non-small cell lung cancer (NSCLC).
Main Methods:
- Retrospective study of 68 early-stage NSCLC patients from January 2013 to January 2020.
- Inclusion of patients undergoing lung surgery with CT-guided localization for extended segmentectomy.
- Outcome measurements included safety margin, complication rate, and postoperative course.
Main Results:
- Mean surgery time: 92.1 min; mean blood loss: 32.8 mL.
- Mean drainage time: 2.3 days; mean hospital stay: 4.9 days.
- Pathological reports confirmed tumor-free resection margins >2 cm in all cases.
Conclusions:
- CT-guided localization followed by extended segmentectomy is a safe and effective procedure.
- This technique facilitates lung volume preservation.
- The approach yields excellent clinical outcomes and wide safety margins for early-stage NSCLC.
