PURPOSE To survey image guided radiation therapy (IGRT) practice patterns, as well as IGRT's impact on clinical workflow and planning treatment volumes (PTVs). METHODS AND MATERIALS A sample of 5979 treatment site-specific surveys was e-mailed to the membership of the American Society for Radiation Oncology (ASTRO), with questions pertaining to IGRT modality/frequency, PTV expansions, method ...

We present a novel application of Tensor Network methods in cancer treatment as potential tool to solve the dose optimization problem radiotherapy. In particular, Intensity-Modulated Radiation Therapy (IMRT) technique - that allows treating irregular and inhomogeneous tumors while reducing radiation toxicity on healthy organs is based beamlets intensities. The aims maximize delivery therapy avo...

BACKGROUND Over the past decade, intensity-modulated radiation therapy (IMRT) has gained widespread use in the treatment of head and neck cancer. METHODS All patients with squamous cell carcinoma of the oropharynx treated with primary IMRT with or without chemotherapy over a 5-year period were reviewed. Outcomes and morbidity were analyzed and compared with previously published data. RESULT...

Introduction: The Aeroform tissue expander device (ATED) is a novel alternative system for patients who have had mastectomy breast cancer (BC) and require adjuvant radiation therapy (RT), investigations are required when used during RT. We aim to compare RT dosimetry outcomes using volumetric modulated arc (VMAT) versus tangential intensity-modulated (t-IMRT) techniques planning post-mastectomy...

PURPOSE Radiation therapy (RT) is delivered as adjuvant and salvage therapy after radical prostatectomy for prostate cancer. Interest in dose escalation in this setting may necessitate more advanced RT techniques, such as intensity modulation. This study was designed to compare intensity-modulated radiation therapy (IMRT) versus 3-dimensional conformal radiation therapy (3DCRT) planning. METH...

Cancer of the parotid gland is relatively rare, but carries poor prognosis owing to its prevailing distant metastases. In addition to the disease's basic epidemiology and pathology, we review some current discoveries of its tumorigenesis molecular mechanism. Based on published salivary gland cancer clinical trial data, non-surgical antitumor efficacies amongst a range of chemotherapy, radiation...

The aims of this study are to design, construct and evaluate the applicability of a head and neck Perspex phantom for dosimetric verification of intensity modulated radiation therapy (IMRT). Thermoluminescent dosimeters (TLDs) was used in this study. Consistency of the fabricated phantom readings was checked by multiple IMRT irradiations. The inter-fraction standard deviation among all TLDs’ me...

PURPOSE Spine stereotactic radiosurgery (SRS) delivers an accurate and efficient high radiation dose to vertebral metastases in 1-5 fractions. We aimed to compare volumetric modulated arc therapy (VMAT) to static beam intensity modulated radiotherapy (IMRT) for spine SRS. METHODS AND MATERIALS Ten spine lesions of previously treated SRS patients were planned retrospectively using both IMRT an...

BACKGROUND Linear Accelerator-based Intensity Modulated Radiation Therapy (IMRT), either as step-and shoot (SS) or in dynamic mode, is now considered routine in the definitive management of head and neck squamous cell carcinoma (HNSCC). Helical TomoTherapy (HT) is a new platform to deliver IMRT. This study aims to compare step-and-shoot Intensity Modulated Radiation Therapy (SS IMRT) with dynam...
