Summary
This review updates radiotherapy planning for prostate cancer, focusing on organs at risk and toxicity. It highlights dose-response relationships and patient risk factors influencing outcomes.
Area of Science:
- Radiation Oncology
- Medical Physics
Background:
- Prostate cancer radiotherapy planning requires optimization of organs at risk.
- Previous reviews exist, necessitating an updated educational resource.
Purpose of the Study:
- To provide a comprehensive review of organs at risk in prostate cancer radiotherapy planning.
- To update knowledge on dose-volume effects and toxicity prediction.
Main Methods:
- Literature review of PubMed and MEDLINE (Jan 2009 - Sep 2015).
- Focus on external beam radiotherapy, including post-prostatectomy.
- Inclusion of dose-volume effects, normal tissue complication probability (NTCP), and predictive models.
Main Results:
- Gastrointestinal and urinary toxicity show dose-response relationships.
- Clinical and patient-related risk factors modify these dose-response relationships.
- Data on erectile dysfunction, bowel, and hematological toxicity are also presented.
Conclusions:
- Quantitative data support dose-response relationships for key toxicities in prostate cancer radiotherapy.
- Patient-specific factors are crucial for modifying toxicity risk.
- This review serves as an update for optimizing radiotherapy planning.

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

01:23Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
