Obstructing endobronchial bands complicating radiation therapy for lung carcinoma

Area of Science:

• Pulmonology
• Oncology
• Radiation Oncology

Background:

• Small cell lung carcinoma (SCLC) is a highly aggressive malignancy.
• External beam radiation therapy is a standard treatment for SCLC.
• Airway complications can arise post-radiation, but are typically acute.

Observation:

• A 57-year-old male patient with SCLC presented with symptoms of airway obstruction.
• Endobronchial bands were identified five months after completing external beam radiation therapy.
• These bands were determined to be benign.

Findings:

• The benign endobronchial bands represented an unusual delayed complication of radiation therapy.
• The patient experienced significant airway obstruction due to these bands.
• Laser ablation was performed to remove the obstructing bands.

Implications:

• This case highlights a rare, delayed benign complication of radiation therapy for airway tumors.
• It underscores the importance of considering delayed complications in patients treated with radiation.
• Laser ablation offers an effective therapeutic option for managing such rare post-radiation airway obstructions.
