CT-guided interstitial HDR-brachytherapy for recurrent glioblastoma multiforme: a 20-year single-institute experience.

Purpose: To report our results of computed tomography-guided interstitial high-dose-rate (HDR) brachytherapy (BRT) in the treatment of patients with recurrent inoperable glioblastoma multiforme (GBM).

Patients And Methods: Between 1995 and 2014, 135 patients were treated with interstitial HDR BRT for inoperable recurrent GBM located within previously irradiated volumes. Patient's median age was 57.

Long-term results of targeted intraoperative radiotherapy (Targit) boost during breast-conserving surgery.

Purpose: We have previously shown that delivering targeted radiotherapy to the tumour bed intraoperatively is feasible and desirable. In this study, we report on the feasibility, safety, and long-term efficacy of TARGeted Intraoperative radioTherapy (Targit), using the Intrabeam system.

Methods And Materials: A total of 300 cancers in 299 unselected patients underwent breast-conserving surgery and Targit as a boost to the tumor bed.

Targeted intraoperative radiotherapy (TARGIT) yields very low recurrence rates when given as a boost.

Purpose: Patients undergoing breast-conserving surgery were offered boost radiotherapy with targeted intraoperative radiotherapy (TARGIT) using the Intrabeam system to test the feasibility, safety, and efficacy of the new approach.

Methods And Materials: We treated 302 cancers in 301 unselected patients. This was not a low-risk group.

TARGeted Intraoperative radiotherapy (TARGIT): an innovative approach to partial-breast irradiation.

A revolution is challenging the dogma that local treatment for all patients with breast cancer treated with breast conservation therapy must include postoperative radiotherapy delivered to the whole breast. Such prolonged postoperative radiotherapy is a burden to patients and hospitals and forces many women to chose mastectomy instead. Furthermore, for patients receiving chemotherapy, the start of conventional radiotherapy may be delayed so long as to increase the risk of local relapse.

Intraoperative radiotherapy for breast cancer.

Postoperative radiotherapy, which forms part of breast-conserving therapy, may not need to encompass the whole breast. Apart from the consumption of huge resources and patients' time, postoperative radiotherapy deters many women from receiving the benefits of breast-conserving surgery, forcing them to choose a mastectomy instead. If radiotherapy could be given in the operating theatre immediately after surgery, many of these disadvantages could be overcome.

Use of low-energy X-rays in the treatment of superficial nonmelanomatous skin cancers.

The Photon Radiosurgery System (PRS), developed by the Photoelectron Corporation in Lexington, Massachusetts, produces low-energy x-rays from the tip of a needle-like probe at a high dose-rate. This portable device can be located directly over the target volume, delivering a uniform dose while sparing surrounding normal structures. To evaluate its radiotherapeutic profile, a prospective phase I Food and Drug Administration trial was performed utilizing this device in the management of nonmelanomatous skin cancers.
