Long-Term Clinical Results of IGRT in Prostate Cancer Treatment.

Background: The combination of intensity modulated radiation therapy (IMRT) and image guided radiotherapy (IGRT) plays a significant role in sparing normal tissue during prostate cancer treatment. We report the clinical outcomes of 260 patients treated with high-dose IGRT as well as the toxicity of high-dose IGRT in these patients.

Materials And Methods: From September 2008 to February 2012, 260 men with clinically localized prostate cancer underwent radical radiotherapy.

Audio-visual navigation reduces treatment time in deep-inspiration breath hold radiotherapy.

Aims: The purpose of this study was to compare the treatment times for deep-inspiration breath hold with and without audio-visual (A-V) navigation.

Methods: We measured the real treatment time in 60 patients with breast cancer undergoing postoperative radiotherapy. Thirty consecutive patients were treated without deep-inspiration breath hold (DIBH) and another 30 patients using deep-inspiration breath hold (10 patients with DIBH only, 10 patients with DIBH using visual feedback and 10 patients with DIBH using visual feedback following breath training).

Comparing morbidity and cancer control after 3D-conformal (70/74 Gy) and intensity modulated radiotherapy (78/82 Gy) for prostate cancer.

Purpose: The purpose of this work was to compare toxicity and cancer control between patients with prostate cancer treated using three-dimensional conformal radiotherapy (3D-CRT) and those treated using intensity-modulated radiation therapy (IMRT).

Methods And Materials: A total of 553 patients with prostate cancer were treated with 3D-CRT 70-74 Gy (3D-CRT 70, 3D-CRT 74) or IMRT 78-82 Gy (IMRT 78, IMRT/SIB 82). Late toxicity was scored according to FC-RTOG/LENT criteria.

[Five-year results of IMRT for prostate cancer - tumor control].

Background: Intensity-modulated radiation therapy (IMRT) is the method of choice in external-beam radiotherapy tolocalized prostate cancer. This work analyses five year results of IMRT with a dose of 78/82 Gy.

Patients And Methods: From June 2003 to December 2007, the IMRT technique was employed to treat 233 patients with T1-3 N0 M0 prostate cancer.

Perioperative interstitial CT-based brachytherapy boost in breast cancer patients with breast conservation after neoadjuvant chemotherapy.

Intraoperative placement of catheters in the tumor bed during breast-conserving surgery (BCS) enables postponed targeted boost irradiation in high risk breast cancer patients. Twenty-three patients with high risk breast cancer underwent neoadjuvant chemotherapy and multifractionated perioperative brachytherapy as a boost to the tumor bed using three-dimensional (3D) CT-based planning. Plastic catheters for brachytherapy were implanted during surgery and targeted irradiation was delivered in the course of 2-3 weeks.
