Hypothesis
Can endobronchial ultrasound accurately assess tracheobronchial tree invasion in cT4b esophageal cancer patients after definitive chemoradiotherapy?
Conclusion
Endobronchial ultrasound is effective in assessing tracheobronchial tree invasion in cT4b esophageal cancer patients after treatment, aiding in patient selection for surgery.
Supporting Evidence
- 90% of patients without tracheobronchial invasion achieved radical resection.
- The study included 26 patients who underwent endobronchial ultrasound.
- Persistent ingrowth was observed in six patients, with follow-up evaluations showing changes in tumor status.
Takeaway
Doctors used a special ultrasound to see if cancer had spread in patients' airways after treatment, helping them decide who could safely have surgery.
Methodology
Patients with suspected tracheobronchial invasion underwent endobronchial ultrasound and were evaluated for surgery based on the results.
Potential Biases
Inter- and intra-observer variability in EBUS interpretation may affect results.
Limitations
The study's retrospective nature and the exclusion of patients with persistent ingrowth limit the generalizability of the findings.
