'Quality assurance' is all those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy the given requirements for quality (ISO 9000:1994). As such it is wide ranging, covering all relevant procedures, activities and actions, and hence all groups of staff involved in the process under consideration. 12.1.1.2. Quality assurance in radiother...

procedures, but between procedures in which more, and procedures in which less, is at stake. In this regard, external-beam radiotherapy does not differ relevantly from technically more invasive procedures such as brachytherapy. The authors reject the argument that implicit consent has been obtained simply because a “patient attends for consultation and follows through on all of the multiple ste...

For the first time in their history, the 2 medical organizations most responsible for the treatment of prostate cancer in the United States—the American Society for Radiation Oncology (ASTRO) and the American Urological Association (AUA)—have issued a joint guideline, a series of 9 major statements on the use of radiation therapy (either adjuvant or salvage) after prostatectomy. The statements ...

A retrospective analysis is presented of the results of external beam radiotherapy for retinoblastoma utilising an accurate lens sparing technique. Local tumour control has been assessed in a consecutive series of 67 eyes in 53 children all of whom received external beam radiotherapy as the primary treatment of retinoblastoma. Follow up ranged from 12 to 82 months (median 35 months) with 76% of...

In this paper we aim to present the methodology used in an Ergonomics research work define preparation for treatment external radiotherapy. This concerns analysis of radiotherapy activity and difficulties workers are experiencing. Lack fluidity during step between different actors was noted by IRSN (Institute Radioprotection Nuclear Safety) experts ASN (Nuclear Safety Authority). assumes that t...

BACKGROUND Gel polymers are considered as new dosimeters for determining radiotherapy dose distribution in three dimensions. OBJECTIVE The ability of a new formulation of MAGIC-f polymer gel was assessed by experimental measurement and Monte Carlo (MC) method for studying the effect of gold nanoparticles (GNPs) in prostate dose distributions under the internal Ir-192 and external 18MV radioth...

BACKGROUND Adjuvant radiotherapy is common for uterine corpus cancer patients, yet the long-term carcinogenic effects of different types of radiotherapy have not been studied adequately. METHODS Second primary cancer risks were quantified in a cohort of 60,949 individuals surviving > or = 1 year of uterine corpus cancer diagnosed from 1973 to 2003 in Surveillance, Epidemiology and End Results...

BACKGROUND A new device, Intrabeam, is available for intraoperative radiotherapy. We have prospectively examined its feasibility and tolerability in delivering adjuvant breast cancer treatment. METHODS Thirty-five patients undergoing breast-conserving surgery received targeted tumour bed irradiation consisting of 5 Gy (at 10 mm) in a single fraction. This single intraoperative treatment was u...
