Intraoperative high-dose-rate brachytherapy

Surgical Oncology Clinics of North America, 2003
Although several modalities have been discussed, a comprehensive intraoperative program should have IOERT, IOHDR, and perioperative brachytherapy facilities available to treat all sites. Interstitial brachytherapy is preferable for the treatment of gross residual tumor; IORT (IOERT for accessible sites and IOHDR for poorly accessible sites) is added to

High Dose-Rate Versus Low Dose-Rate Brachytherapy for Lip Cancer

International Journal of Radiation Oncology*Biology*Physics, 2012
To analyze the outcome after low-dose-rate (LDR) or high-dose-rate (HDR) brachytherapy for lip cancer.One hundred and three patients with newly diagnosed squamous cell carcinoma of the lip were treated between March 1985 and June 2009 either by HDR (n = 33) or LDR brachytherapy (n = 70).

Cervix cancer brachytherapy: High dose rate

Cancer/Radiothérapie, 2014
Cervical cancer, although less common in industrialized countries, is the fourth most common cancer affecting women worldwide and the fourth leading cause of cancer death. In developing countries, these cancers are often discovered at a later stage in the form of locally advanced tumour with a poor prognosis.

Postoperative management of keloids: Low-dose-rate and high-dose-rate brachytherapy

Brachytherapy, 2014
We report the experience of the Radiation Oncology Department of the European Institute of Oncology in Milan, Italy, on the adjuvant low-dose-rate (LDR) and high-dose-rate (HDR) interstitial brachytherapy. Brachytherapy might be useful to improve keloids recurrence rate or reduce keloids treatment side effects instead of external beam radiotherapy.Data

Comparison of high dose-rate and low dose-rate dose distributions for vaginal cylinders

International Journal of Radiation Oncology*Biology*Physics, 1995
The identification of appropriate high dose-rate parameters required to produce a "uniform" dose distribution on the surface of a vaginal cylinder. The high dose-rate dose distribution is then compared to the traditional low dose-rate dose distributions obtained with Burnett cylinders.Dose distributions were calculated for 2, 3, and 3.5 cm diameter ...

Comparison of high dose rate, low dose rate, and high dose rate fractionated radiation for optimizing differences in radiosensitivities in vitro

Radiation Oncology Investigations, 1998
Radiotherapy is administered with the assumption that all patients respond similarly to radiation although radiosensitivity does vary from patient to patient, resulting in different degrees of early and late effects. Because the dose given to a patient is limited by the response of normal tissue in the treatment field, it would be beneficial to ...

High Dose Rate Prostate Brachytherapy

2021
High Dose Rate (HDR) brachytherapy is a safe and effective method of treating men with prostate cancer. It is used in the definitive setting as monotherapy or in combination with hormonal therapy and/or external beam radiation therapy. It is also used in the salvage setting for local recurrence after primary radiotherapy.

Definition of vaginal doses in intrauterine high–dose-rate brachytherapy

Brachytherapy, 2004
The aim of this study was to evaluate dosimetric aspects of high-dose-rate (HDR) intrauterine brachytherapy applications and to discuss a possible definition of vaginal points for dose reporting.HDR brachytherapy was performed using a "Fletcher-like" applicator. Doses to the vaginal mucosa were assessed using 2 sets of points for each ovoid.

Chromosome Breakage at High Radiation Dose-Rates

Nature, 1958
THE variation of the frequency of chromosomal aberrations as a function of radiation dose-rate has been the subject of numerous experimental investigations, and the results of such studies have been of considerable importance in formulating theories of the basic mechanisms of radiation action1. With the recent availability of radiation sources of great

High dose rate brachytherapy source measurement intercomparison

Australasian Physical & Engineering Sciences in Medicine, 2017
This work presents a comparison of air kerma rate (AKR) measurements performed by multiple radiotherapy centres for a single HDR 192Ir source. Two separate groups (consisting of 15 centres) performed AKR measurements at one of two host centres in Australia.
