Endobronchial brachytherapy and external-beam radiotherapy in patients with endobronchial obstruction and extrabronchial extension.

Purpose: To evaluate the efficacy of high-dose rate endobronchial brachytherapy (HDR-EB) with concomitant short-course external-beam radiotherapy (EBRT) in patients with both endobronchial and extrabronchial tumor.

Methods And Materials: Patients with endobronchial disease and extrabronchial lesions greater than 2.5cm were treated with three 5Gy HDR-EB and 37.

Analysis of serial CT scans to assess template and catheter movement in prostate HDR brachytherapy.

Purpose: As prostate high-dose-rate (HDR) brachytherapy becomes more prevalent, varying amounts of catheter displacement have been noted. To investigate the constancy of catheter position and its impact on dose distribution, we analyzed serial dosimetric CT scans.

Methods And Materials: The data from 50 patients were analyzed.

The effects of edema on urethral dose following palladium-103 prostate brachytherapy.

The effects of edema on urethral dose after interstitial prostate brachytherapy with palladium-103 (103Pd) were studied. Fifty patients underwent a 90-Gy 103Pd implant followed by dosimetric computed tomography (CT). Twenty-one days later, a Foley catheter was reinserted and a dosimetric CT was repeated.
