Simultaneous Integrated Boost by Volumetric Modulated Arc Therapy (VMAT) with Concurrent Mitomycin and Capecitabine in Anal Canal Carcinoma [PDF]

Middle East Journal of Cancer, 2019
Background: Combined treatment with radiotherapy and chemotherapy is the standard approach in non-metastatic anal carcinoma. Intensity-modulated radiotherapy and volumetric modulated arc therapy are currently the most accepted radiation techniques.

Comparison of Carotid Artery Dose in Early-Stage Glottic Cancer Treated with 3D-Conformal, Helical-IMRT and VMAT

Forum of Clinical Oncology, 2023
The aim of this study was to compare the dosimetry of carotid arteries (CAs) using three radiation therapy (RT) techniques, three-dimensional conformal RT (3D-CRT), helical tomotherapy-intensity-modulated RT (HT-IMRT), and volumetric modulated arc ...

Risk of second primary cancer from proton arc therapy of pediatric brain tumors

Physics and Imaging in Radiation Oncology, 2023
Proton arc therapy (PAT) is currently explored for clinical implementation, despite its associated low-dose bath. This study therefore aimed at evaluating the risk of radiation-induced second primary cancer (SPC) for PAT in pediatric brain tumor patients.

A comprehensive formulation for volumetric modulated arc therapy planning [PDF]

Medical Physics, 2016
Purpose:Volumetric modulated arc therapy (VMAT) is a widely employed radiation therapy technique, showing comparable dosimetry to static beam intensity modulated radiation therapy (IMRT) with reduced monitor units and treatment time. However, the current VMAT optimization has various greedy heuristics employed for an empirical solution, which ...

Volumetric Modulated Arc Therapy for Advanced Pancreatic Cancer [PDF]

Strahlentherapie und Onkologie, 2010
Intensity-modulated radiotherapy (IMRT) allows for improved sparing of organs at risk (OARs) in advanced pancreatic cancer. A planning study evaluated if volumetric modulated arc therapy (RapidArc [RA]) could be used as an alternative to IMRT in such cases.In ten patients, five-field IMRT (5f-IMRT) plans with fixed gantry positions were compared to RA ...

Evaluation of volumetric modulated arc therapy for postmastectomy treatment [PDF]

Radiation Oncology, 2014
To examine the feasibility of volumetric modulated arc therapy (VMAT) for post mastectomy radiotherapy (PMRT).Fifteen PMRT patients previously treated at our clinic with helical tomotherapy (HT) were identified for the study. Planning target volumes (PTV) included the chest wall and regional lymph nodes.

Transition from 3D conformal to modern modulated craniospinal radiotherapy

South African Journal of Oncology, 2022
Background: Achieving optimal tumour coverage during craniospinal irradiation (CSI) is a challenge. Whilst several critical organs are at risk of radiation-induced toxicity, if target volume structures like the cribriform plate receive less than 95% of ...

Planning system-dependent recommendations of intensity-modulated technique for breast radiotherapy: A literature review-based adaptation and institutional dosimetric experience from a large-volume tertiary cancer care hospital

Journal of Medical Physics, 2023
This article aims to identify, through a literature review, the best intensity-modulated technique (IMRT)/volumetric-modulated arc therapy (VMAT) for the breast/chest wall (Br/CW) as a function of the treatment planning system (TPS) and present the ...

Optimization approaches to volumetric modulated arc therapy planning [PDF]

Medical Physics, 2015
Volumetric modulated arc therapy (VMAT) has found widespread clinical application in recent years. A large number of treatment planning studies have evaluated the potential for VMAT for different disease sites based on the currently available commercial implementations of VMAT planning.
