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.

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.

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 ...

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 ...

Adaptive Radiotherapy in Head and Neck Cancer Using Volumetric Modulated Arc Therapy
Journal of Personalized Medicine, 2022 A dosimetric study was performed to show the importance of adaptive radiotherapy (ART) for head and neck cancer (HNC) patients using volumetric modulated arc therapy (VMAT). A total of 13 patients with HNC who required replanning during radiotherapy were
