Clinical Trials [1495 Associated Clinical Trials listed on BioPortfolio]

Planning Margin Requirements for Pediatric Radiation Oncology

Currently the Planning Target Volume (PTV) and Planning Organs at Risk Volume (PRV) margins used for pediatric radiation treatments are empiric; therefore, a quantitative assessment of the...

Adaptive Dose-Escalated Multi-modality Image-guided RadiothErapy

Patients with primary head and neck squamous cell carcinoma (HNSCC) planned for treatment with radiotherapy with or without chemotherapy in curative setting will be treated with an adaptiv...

BreAst Cancer and Cardiotoxicity Induced by RAdioTherapy: the BACCARAT Study

Breast radiotherapy RT used until the 1990s was clearly responsible for increased mortality due to long term cardiac complications. Since the 2000s, improvements have appeared in dose dist...

Incentivizing Planning & Output in Exercising

This study will test whether incentivizing pre-workout activities (i.e., planning workouts) is more effective than incentivizing actual workouts. This study has two conditions: planning co...

Comparison Between Two Strategies of Discharge Planning for the Reduction of Short Term Hospital Readmissions (PROMENADE)

The purpose of this study is to improve discharge planning effectiveness by comparing two strategies [on-Demand Discharge Planning (DDP) vs. Routine Discharge Planning (RDP)], in terms of ...

Robust radiotherapy planning.

Motion and uncertainty in radiotherapy is traditionally handled via margins. The clinical target volume (CTV) is expanded to a larger planning target volume (PTV), which is irradiated to the prescribe...

Knowledge-based planning for identifying high-risk stereotactic ablative radiotherapy treatment plans for lung tumors larger than 5cm.

Stereotactic ablative body radiotherapy (SABR) for lung tumors ≥5cm, can be associated with more toxicity. We investigated the relationship between dosimetry and toxicity and used a knowledge-based ...

In Silico Trial of MR-Guided Mid-Treatment Adaptive Planning for Hypofractionated Stereotactic Radiotherapy in Centrally Located Thoracic Tumors.

Hypofractionated (>5 fraction) stereotactic radiotherapy (HSRT) may allow for ablative biologically equivalent dose to tumors with a lower risk of organ-at-risk (OAR) toxicity in central thoracic tumo...

Comparison of Flattening Filter and Flattening Filter-Free Volumetric Modulated Arc Radiotherapy in Patients with Locally Advanced Nasopharyngeal Carcinoma.

BACKGROUND This study aimed to investigate the therapeutic role of flattening filter-free (FFF) mode in volumetric modulated arc therapy (VMAT) compared with flattening filter (FF) mode in patients wi...

Accurate, robust and harmonized implementation of morpho-functional imaging in treatment planning for personalized radiotherapy.

In this work we present a methodology able to use harmonized PET/CT imaging in dose painting by number (DPBN) approach by means of a robust and accurate treatment planning system. Image processing and...

Medical and Biotech [MESH] Definitions

Computer-assisted mathematical calculations of beam angles, intensities of radiation, and duration of irradiation in radiotherapy.

Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.

The total amount of radiation absorbed by tissues as a result of radiotherapy.

Areawide planning for hospitals or planning of a particular hospital unit on the basis of projected consumer need. This does not include hospital design and construction or architectural plans.

Recommendations for directing health planning functions and policies. These may be mandated by PL93-641 and issued by the Department of Health and Human Services for use by state and local planning agencies.
