What is GEC-Estro?
Responsibilities. GEC-ESTRO was formed in 1990 from the amalgamation of the The Groupe Européen de Curiethérapie (GEC) and the European SocieTy for Radiotherapy & Oncology (ESTRO).
What is HR CTV?
As defined by GEC-ESTRO, the high risk. CTV (HR-CTV) 2-includes the GTV at the time of brachytherapy plus any MRI grey zones. The HR CTV includes the whole cervix and presumed. extracervical spread.
What is Manchester system in brachytherapy?
The Manchester System of Intracavitary Brachytherapy is the most commonly used system in the world and for a good reason. It was designed with simplicity in mind. However over the last 2 decades with the advent of HDR brachytherapy and treatment planning systems the need for such systems has diminished.
What is image guided adaptive brachytherapy?
Abstract. Purpose of review: Image-guided adaptive brachytherapy (IGABT) is a high-precision radiation that allows defining accurately treatment targets and optimizing their coverage whereas sparing efficiently the surrounding organs at risk.

What is Manchester system?
system today. ∎ Manchester system was meant for radium as the. radioisotope and applicators specially designed to. accommodate those sources following a set of rules to deliver almost a constant dose rate to its dose specification point ‘A’.
What is DAP in radiation?
The dose area product (DAP) is used in assessing the radiation risk from diagnostic X-ray and interventional procedures. The DAP is a surrogate measurement for the total amount of X-ray energy delivered to the patient, and reflects the dose within the radiation field and area of tissue irradiated.
What is the difference between air kerma and DAP?
Kerma-Area Product (KAP) KAP may also be called the dose area product (DAP). The KAP or DAP is the product of the intensity of the radiation beam (air kerma) multiplied by the area of the beam and is the appropriate way to measure the total amount of radiation delivered to the patient.
What are the GEC Estro guidelines for prostate brachytherapy?
The purpose of the paper is to update previously published GEC ESTRO guidelines for prostate brachytherapy. Consensus guidelines are made for Low Dose Rate (LDR) and High Dose Rate (HDR) brachytherapy treatments. New areas include the use of focal and salvage brachytherapy and the role of androgen deprivation therapy.
What is GEC Estro IBS and ABS doing?
In order to arrive at a systematic, uniform and international approach for CT based definition and contouring of target structures, GEC ESTRO, IBS and ABS agreed to jointly develop such recommendations based on the concepts and terms as published in the ICRU Report 89.
What is temporary brachytherapy for prostate cancer?
Temporary brachytherapy involves first placing catheters within the prostate and, on confirmation of accurate positioning, temporarily introducing the radioactive source, generally High Dose Rate (HDR) radioactive sources of Ir-192 or less commonly Co-60.
What is an I-125 source for brachytherapy?
Permanent brachytherapy uses Low Dose Rate (LDR) sources, most commonly I-125, emitting photon radiation over months.
