Background:

Endobronchial tumors cause significant respiratory distress and bleeding.
Traditional treatments may have limitations for certain lesions.

Purpose of the Study:

To evaluate the efficacy of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser therapy for endotracheal and endobronchial lesions.
To assess patient outcomes, including performance status and survival, following laser treatment.

Main Methods:

Flexible bronchoscopy with Nd:YAG laser ablation was used on 40 lesions (36 malignant, 4 benign).
Procedures were primarily performed under general anesthesia.
Most patients required two treatment sessions for complete tumor ablation.

Main Results:

Sixty-three percent of patients showed improvement in Karnofsky Performance Status.
Mean performance status improved by 100% (from 30 to 60) post-treatment.
Mean hospital stay was 48 hours; mean survival was 13 weeks.

Conclusions:

Therapeutic laser bronchoscopy is a valuable adjunctive treatment for selected patients with obstructive or bleeding lung tumors.
Nd:YAG laser offers a minimally invasive option for managing complex endobronchial pathology.
