Organs at risk radiation dose constraints

Cancer/Radiothérapie, 2022
Dose constraints are essential for performing dosimetry, especially for intensity modulation and for radiotherapy under stereotaxic conditions. We present the update of the recommendations of the French society of oncological radiotherapy for the use of these doses in classical current practice but also for reirradiation.

Provider Organizations At Risk: A Profile Of Major Risk-Bearing Intermediaries, 1999 [PDF]

Health Affairs, 2001
Provider organizations have evolved to function as intermediaries between managed care plans and individual providers. These organizations assume much financial risk and care management responsibilities. We profile the characteristics of these organizations in markets across the country.

Organs at risk in lung SBRT

Physica Medica, 2017
Lung stereotactic body radiotherapy (SBRT) is an accurate and precise technique to treat lung tumors with high 'ablative' doses. Given the encouraging data in terms of local control and toxicity profile, SBRT has currently become a treatment option for both early stage lung cancer and lung oligometastatic disease in patients who are medically ...

Dosimetric Evaluation of Organs at Risk From SAVE Protocol

International Journal of Radiation Oncology*Biology*Physics, 2023
The objective of this work was to evaluate dosimetric characteristics to organs at risk (OARs) from short-course adjuvant vaginal cuff brachytherapy (VCB) in early endometrial cancer compared with standard of care (SOC) in a multi-institutional prospective randomized trial.SAVE (Short Course Adjuvant Vaginal Brachytherapy in Early Endometrial Cancer ...

Anatomical contouring variability in thoracic organs at risk

Medical Dosimetry, 2016
The purpose of this study was to determine whether contouring thoracic organs at risk was consistent among medical dosimetrists and to identify how trends in dosimetrist׳s education and experience affected contouring accuracy. Qualitative and quantitative methods were used to contextualize the raw data that were obtained.

Accountable Care Organizations: Is the Radiologist at Risk?

Journal of the American College of Radiology, 2013
Today’s forward-looking discussions on health care seem dominated by “at-risk” contracting, integrated delivery systems, and accountable care organization (ACO) approaches to controlling costs, improving quality, and achieving better patient outcomes. The desirability of these goals is indisputable.

The Organs at Risk and Radiation Tolerance Doses

2012
During the last two decades, early diagnosis and better treatment options have improved the survival rates of breast cancer patients [1]. Radiotherapy (RT) is an essential component of the treatment of patients with early and locally advanced disease and has been shown to reduce local recurrence risk by approximately 20% and breast cancer mortality ...

Organs at Risk (OAR) Tolerance in Hypofractionated Radiosurgery

2020
For CyberKnife radiosurgery, the precise interpretation of the normal probability of tissue complications (NTCP) is extremely important due to the reverse planning algorithm and the non-isocentric irradiation geometry adopted by the system, which requires the setting of dose constraints for any organ at risk (OAR).

Delineating Organs at Risk in Radiation Therapy

2013
Defining organs at risk is a crucial task for radiation oncologists when aiming to optimize the benefit of radiation therapy, with delivery of the maximum dose to the tumor volume while sparing healthy tissues. This book will prove an invaluable guide to the delineation of organs at risk of toxicity in patients undergoing radiotherapy.

Planning organ at risk volume margins for organ motion of the intestine

Radiotherapy and Oncology, 2006
To account for internal organ motion and set-up uncertainties around organs at risk (OR) in radiotherapy (RT), the ICRU report no 62 introduced the planning organ at risk volume (PRV). In the present study, we have quantified PRV margins for the intestine, which is an important OR in pelvic RT.The present study was based on intestine contours outlined ...
