Endoscopic brachytherapy.

Intraluminal radiation for the local control of bronchogenic carcinoma has recently undergone rapid technological progress. Remote afterloading of high intensity radiation sources into endoscopically placed multiple small catheters with computerized optimization of dosimetry is the state-of-the-art. Fractionated high dose rate (HDR) outpatient treatment has been shown to reduce airway obstruction and improve performance status and quality of life.
