Summary
Thoracoscopic staging accurately assesses esophageal cancer lymph node involvement before surgery. This minimally invasive approach improves staging accuracy, guiding treatment decisions and potentially improving patient outcomes.
Area of Science:
- Oncology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Esophageal cancer staging is crucial for treatment planning.
- Adjuvant therapy for esophageal cancer shows survival benefits but carries high morbidity.
- Accurate preoperative staging is essential for optimal adjuvant therapy allocation.
Purpose of the Study:
- To evaluate the accuracy of thoracoscopic lymph node staging in esophageal cancer.
- To determine if thoracoscopy provides reliable pre-resection staging information.
- To assess the role of thoracoscopy in identifying thoracic lymph node involvement and distant metastases.
Main Methods:
- Esophageal cancer patients underwent CT, MRI, and endoesophageal ultrasonography.
- Thoracoscopic staging was performed via left-sided thoracoscopy with biopsy of specific lymph node stations (ATS levels 5, 6, 8, 9).
- Complete intraoperative lymph node sampling was performed during subsequent resection.
Main Results:
- Thoracoscopic staging was successful in 13 of 14 patients.
- All successfully staged patients had accurate thoracic lymph node staging confirmed at surgery.
- Thoracoscopy identified pulmonary metastases in two patients and revealed discrepancies with cross-sectional imaging in lymph node status.
Conclusions:
- Thoracoscopic lymph node staging is an accurate method for pre-resection staging in esophageal cancer.
- This technique provides reliable information on thoracic lymph node involvement.
- Accurate staging via thoracoscopy can inform treatment decisions and improve patient management.
