IMRT Safety the Focus of New ASTRO Report
The report broadly addresses safe delivery of IMRT, with a primary focus on recommendations for human error prevention and methods to reduce the occurrence of errors or machine malfunctions that can lead to errors or “catastrophic failures,” ASTRO officials said. More »
IMRT for Anal Cancer Reduces Worst Radiotherapy Toxicities
Compared to conventional radiotherapy, IMRT minimizes serious toxicity among anal cancer patients, according to a study reported at last week's ASCO Gastrointestinal Cancers meeting. More »
Latest PARSPORT Results Confirm: IMRT Greatly Reduces Treatment Effects in Head and Neck Cancer
Two-year results from the largest randomized trial of IMRT in head and neck cancer confirm that it dramatically reduces the risk of dysphagia and xerostomia. The study was too small to establish a survival advantage, although the results are encouraging. More »
Is concurrent chemotherapy/IMRT too toxic and dangerous for use in H&N cancer?
SAN FRANCISCO—In a recent debate, both speakers agreed that IMRT with concurrent chemotherapy is toxic in patients with head and neck cancer, but disagreed on whether the risk/benefit ratio justifies its use. The event was held at the 2008 International Conference on Head and Neck Cancer, sponsored... More »
Report finds high rate of adoption of IMRT
DES PLAINES, Illinois—Fully 87% of U.S. radiation oncology sites have adopted intensity-modulated radiation therapy (IMRT), according to the “2007 Radiation Oncology Market Summary Report.” More »
Oropharyngeal ca: IMRT spares salivary glands
BOSTON—A multicenter trial that tested intensity-modulated radiation therapy for patients with early-stage oropharyngeal cancer showed a reduction in long-term salivary toxicity while achieving good tumor control, according to research presented at ASTRO 2008. More »
Breast IMRT reduces acute radiation-induced dermatitis
Using intensity-modulated radiation therapy for breast cancer patients after lumpectomy can reduce the incidence of acute dermatitis, compared with traditional whole-breast radiotherapy, reported Jean-Philippe Pignol, MD, of Sunnybrook Health Sciences Centre, Toronto, and colleagues. More »
Hypofractionated IMRT does not increase sexual side effects
Compared with conventional intensity-modulated radiation therapy for prostate cancer, hypofractionated IMRT is not associated with any increase in sexual adverse effects, finds a randomized trial. More »
IMRT of the Breast Markedly Reduces Moist Desquamation
In a randomized trial, breast cancer patients who underwent postoperative intensity modulated radiation therapy (IMRT) had a markedly reduced incidence of moist desquamation and overall skin toxicity, compared with those receiving standard radiation therapy. More »
High-dose IMRT proven effective in treating prostate cancer
After nearly a decade of intensity-modulated radiation therapy barriers to its adoption remain, ranging from the high cost of technology to fundamental changes in the practice of medicine. Now, a study conducted at Memorial Sloan-Kettering Cancer Center may help overcome those obstacles, as it... More »

Extranodal natural killer/T-cell lymphoma (ENKTL), nasal type, is a rare form of non-Hodgkin lymphoma. Treatment of ENKTL primarily relies on radiation; thus, proper delineation of target volumes is critical. Currently, the ideal modalities for delineation of gross tumor volume for ENKTL are unknown. We describe three consecutive cases of localized ENKTL that presented to the Nova Scotia Cancer Centre in Halifax, Nova Scotia. All patients had a planning CT and MRI as well as a planning FDG-PET/CT in the r

Little attention has been paid to the fact that intensity modulated radiation therapy (IMRT) techniques do not easily enable treatment with opposed beams. Three treatment plans (3 D conformal, IMRT, and combined (anterior-posterior-posterio-anterior (AP-PA) + IMRT) of 7 patients with centrally-located lung cancer were compared for exposure of lung, spinal cord and esophagus. Combined IMRT and AP-PA techniques offer better lung tissue sparing compared to plans predicated solely on IMRT for centrally-locate

Radiation induced secondary cancers are a rare but severe late effect after breast conserving therapy. Intraoperative radiotherapy (IORT) is increasingly used during breast conserving surgery. The purpose of this analysis was to estimate secondary cancer risks after IORT compared to other modalities of breast radiotherapy (APBI - accelerated partial breast irradiation, EBRT - external beam radiotherapy).|Radiation induced secondary cancers are a rare but severe late effect after breast conserving therapy.

Conventional external beam radiotherapy is a standard procedure for treatment of spinal metastases. In case of progression spinal cord tolerance limits further radiotherapy in pre-irradiated areas. Spinal stereotactic radiotherapy is a non-invasive option to re-treat pre-irradiated patients. Nevertheless, spinal radiosurgery results in relevant dose deposition within the myelon with potential toxicity. Aim of the study was to retrospectively analyse the efficacy and feasibility for salvage radiosurgery of
