Laser therapy in 100 tracheobronchial tumours.

Area of Science:

• Pulmonology
• Oncology
• Laser Medicine

Background:

• Tracheobronchial tumors cause significant morbidity, including airway obstruction, lung collapse, and hemoptysis.
• Conventional treatments like radiotherapy and chemotherapy have limitations, especially in inoperable patients.
• Neodymium YAG (yttrium-aluminium-garnet) and argon lasers offer a potential therapeutic option for intraluminal tumor management.

Purpose of the Study:

• To evaluate the efficacy and safety of laser phototherapy for tracheobronchial tumors.
• To assess outcomes in patients with airway obstruction, lung collapse, or hemoptysis due to intraluminal tumors.
• To determine the role of laser therapy as an adjunct to conventional treatments in inoperable patients.

Main Methods:

• A cohort of 100 patients with tracheobronchial tumors underwent treatment with neodymium YAG or argon laser.
• Patients presented with symptoms of airway obstruction (59), lung collapse (17), or hemoptysis (24).
• Seventy-four patients had failed or relapsed from prior radiotherapy or chemotherapy and were deemed inoperable.

Main Results:

• Objective improvement in lung function or hemoptysis was observed in 63% of airway obstruction cases, 29% of lung collapse cases, and 58% of hemoptysis cases.
• Overall, 68 patients experienced symptomatic benefit, with objective improvement noted in 56 patients.
• Two treatment-related deaths occurred due to asphyxia from hemorrhage in patients with advanced cylindromas and critical airway narrowing.

Conclusions:

• Laser phototherapy is a valuable addition to conventional treatment for suitable patients with intraluminal tracheobronchial tumors.
• The procedure demonstrated significant symptomatic and objective benefits for patients with airway obstruction, lung collapse, and hemoptysis.
• While effective, careful patient selection and management are crucial due to potential risks, such as asphyxia from hemorrhage.
