Purpose:
to report on the use of high-dose-rate (HDR) endobronchial interventional radiotherapy (brachytherapy, EBIRT) for palliation of symptoms in patients with lung cancer.
Patients And Methods:
retrospective review of lung cancer patients treated with HDR-EBIRT at our institution (1995-2017). Treatment results and treatment related toxicity were recorded. Clinical response was subjectively evaluated within 3 months after treatment. Overall survival (OS) was analyzed.
Results:
347 patients were identified. The median age was 69 years and the median follow-up time was 13.4 months. Most patients received external beam radiation therapy during the primary treatment. Within 3 months, 87.7% of the patients had complete or major response of their presenting symptoms. OS was 55.2% at 1 year, 18.3% at 2 years. Patients who had complete or major response had a longer median survival than other patients (13 versus 7 months, p = 0.03). Chronic bronchitis was found in 26.8%, while 7.8% of the patients died due to uncontrollable hemoptysis.
Conclusion:
HDR-EBIRT is a safe and effective treatment option for the palliative treatment of lung cancer patients. HDR-EBIRT is most suitable as a re-irradiation technique. Further clinical studies are needed to validate its role.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
