Summary
Sentinel node identification is crucial for staging small non-small cell lung cancer. Both indocyanine green and computed tomography lymphography are quick, effective methods for identifying sentinel nodes during surgery or bronchoscopy.
Area of Science:
- Oncology
- Surgical Oncology
- Medical Imaging
Background:
- Sentinel lymph node biopsy is vital for accurate staging in early-stage non-small cell lung cancer (NSCLC) patients.
- Accurate staging is essential for determining eligibility for lung-sparing segmentectomy.
- Current methods for sentinel node identification can be time-consuming and complex.
Purpose of the Study:
- To evaluate the efficacy and efficiency of intraoperative sentinel node identification techniques for NSCLC patients undergoing segmentectomy.
- To determine if indocyanine green (ICG) and computed tomography lymphography (CTL) are suitable for routine clinical practice.
Main Methods:
- Sentinel node identification was performed using intraoperative indocyanine green (ICG) injection.
- Preoperative sentinel node identification was achieved using computed tomography lymphography (CTL) via transbronchial injection of iopamidol.
- Procedure time for sentinel node identification was recorded.
Main Results:
- Both ICG and CTL methods demonstrated successful sentinel node identification.
- The identification process for both methods took approximately 10 minutes.
- These techniques integrate seamlessly with standard surgical and bronchoscopic procedures.
Conclusions:
- Intraoperative ICG and preoperative CTL are efficient and practical methods for sentinel node identification in NSCLC patients.
- These techniques can be readily adopted into daily medical practice, aiding in surgical planning and patient eligibility assessment for segmentectomy.
