Summary
Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy effectively relieves airway stenosis and defines tumor borders before tracheobronchial surgery. This approach expands surgical indications for lung and tracheal tumors, improving patient outcomes.
Area of Science:
- Oncology
- Pulmonology
- Surgical Oncology
Background:
- Tracheobronchial tumors, including lung cancer and metastatic tracheal tumors, often present with airway stenosis, complicating surgical management.
- Endoscopic therapies are increasingly explored to improve surgical outcomes for these challenging conditions.
Observation:
- Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy was applied preoperatively in eight patients undergoing tracheobronchial surgery.
- The study included six patients with lung cancer and two with metastatic tracheal tumors.
Findings:
- Preoperative Nd:YAG laser therapy proved beneficial for relieving airway stenosis, enabling precise delineation of tumor margins, and facilitating endotracheal intubation for anesthesia.
- The combination of Nd:YAG laser therapy with chemotherapy and/or radiation therapy expanded the range of cases suitable for surgical intervention.
- Careful preoperative evaluation of resection limits and reconstruction methods is crucial, with intraoperative histological assessment guiding dissection for radical tumor removal.
Implications:
- Nd:YAG laser therapy represents a valuable endoscopic tool for optimizing surgical planning and execution in tracheobronchial tumor resections.
- This technique can potentially increase the number of patients eligible for curative-intent surgery.
- Integration of endoscopic laser therapy with multimodal treatment strategies may enhance oncological control and patient survival.
