Cardiac-sparing radiotherapy for the left breast cancer with deep breath-holding.

Purpose: The aim of this study was to evaluate the effect of decreasing the irradiated cardiac volume in breast-conserving therapy (BCT) using breath-adapted radiation therapy (BART).

Materials And Methods: The radiation therapy (RT)-computed tomography (CT) of 21 patients with left breast cancer during free breathing (FB), end-inspiration gating (IG) with audio-prompting, and deep inspiration breath-hold (DIBH) were subjected to BART planning analysis. Respiratory movement was monitored during CT scanning with the respiratory-gating system.

Transperineal high-dose-rate interstitial radiation therapy in the management of gynecologic malignancies.

Background: High-dose-rate interstitial radiation therapy is a newly introduced modality, and its role in the management of gynecologic malignancies remains to be studied. Clinical experience in high-dose-rate interstitial radiation therapy was retrospectively investigated.

Patients And Methods: Eight patients with primary and nine with recurrent gynecologic malignancies underwent high-dose-rate interstitial radiation therapy with/without external-beam irradiation.
