PO-0939: The dosimetric consequences of delineation variation for cervical external beam radiotherapy

Dosimetric Characteristics of Transparent Bolus for External Beam Radiotherapy

Introduction: In radiotherapy, the bolus is often used while treating the tumor under the uneven surfaces of the patients for correcting the anatomical irregularities and increasing skin dose. Wet cotton and wet gauze are still used in developing countries, since the use of wet cotton and wet gauze has certain disadvantages, there is a need for transparent bolus which ...

Consent to external-beam radiotherapy.

Canadian law, and the physician's code of ethics, requires that informed consent be obtained before any medical act is performed. However, there are no rules about how consent is to be obtained and by whom, and how that consent is to be documented.In April 2008, we asked the heads of all Canadian radiation oncology departments to tell us whether their centre uses a written consent form for exte...

Hypofractionated External-Beam Radiotherapy for Prostate Cancer

There are radiobiological rationales supporting hypofractionated radiotherapy for prostate cancer. The recent advancements in treatment planning and delivery allow sophisticated radiation treatments to take advantage of the differences in radiobiology of prostate cancer and the surrounding normal tissues. The preliminary results from clinical studies indicate that abbreviated fractionation prog...
