A Retrospective Planning Analysis Comparing Volumetric-Modulated Arc Therapy (VMAT) to Intensity-Modulated Radiation Therapy (IMRT) for Radiotherapy Treatment of Prostate Cancer.

Purpose: This study aims to compare intensity-modulated radiation therapy (IMRT) to volumetric-modulated arc therapy (VMAT) for the treatment of prostate cancer. Particular focus was placed on the impact IMRT and VMAT have on departmental planning and treatment resources.

Materials And Methods: Twenty prostate cancer cases were retrospectively planned to compare 5-field IMRT to VMAT using a single arc (VMAT-1A) and 2 arcs (VMAT-2A).

An Introduction to the Intensity-modulated Radiation Therapy (IMRT) Techniques, Tomotherapy, and VMAT.

The goal of radiation therapy is to administer a therapeutic dose of radiation to a target while limiting the side effects caused by delivering the dose to surrounding tissues and vital organs. The ongoing pursuit to achieve an optimal dose distribution has prompted the radiation therapy profession to develop new techniques that incorporate advances in technology. In radiation therapy today, modern techniques that include three-dimensional conformal radiation therapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) are routinely used in the treatment of cancers.

Disruption to radiation therapy sessions due to anxiety among patients receiving radiation therapy to the head and neck area can be predicted using patient self-report measures.

Objective: This analysis sought to determine whether patient self-report measures were associated with disruption to radiation therapy sessions due to anxiety among cancer patients undergoing radiation therapy to the head and neck region.

Method: A cohort of patients undergoing radiation therapy to the head and neck region at a major regional radiation oncology treatment centre (ROTC) in Australia completed self-report measures of anxiety, history of panic and fears relevant to use of an immobilising mask. The treating Radiation Therapist (RT) rated the level of session disruption due to patient anxiety during the Computerised Tomography/Simulation (CT/Sim) (baseline) session and first treatment session.
