To evaluate dynamic conformal arc therapy (DAT) dose distribution and clinical applicability in comparison to intensity modulated radiotherapy (IMRT) in different types of tumors and locations, twelve patients with prostate cancer with no node involvement and three patients with single tumors in the pituitary, in the neck and in the thoracic spinal region treated with IMRT, were retrospectively...

BACKGROUND The objective of this study was to assess the current level of intensity-modulated radiation therapy (IMRT) use in the United States. METHODS Three-hundred thirty-three randomly selected radiation oncologists were sent a 13-question survey regarding IMRT use. IMRT users were asked about the number of patients and sites treated, their reasons for adopting IMRT, and future plans for ...

Introduction: Synovial sarcoma makes up 8–10% of all soft tissue sarcomas, and constitutes 3–10% of all sarcomas occurring in the head and neck region. It shows male predominance (3:2), and the mean age of presentation is 30 years.   Case Report: A 51-year-old gentleman presented with right-sided neck swelling which had been progressively increasing in size for the past 2 years. A computed ...

Efforts to improve the efficacy of treatment for SCCHN have led to the use of multimodality approaches with combinations of surgery, radiotherapy and chemotherapy. Conventional head and neck radiotherapy, a standard approach for locoregionally advanced disease, is associated with a variety of well-known acute and long-term toxicities. These chronic toxicities (i.e. xerostomia, dysphagia, fibros...

BACKGROUND Compared to static beam Intensity-Modulated Radiation Therapy (IMRT), the main advantage of Volumetric Modulated Arc Therapy (VMAT) is a shortened delivery time, which leads to improved patient comfort and possibly smaller intra-fraction movements. This study aims at a treatment planner-independent comparison of radiotherapy treatment planning of IMRT and VMAT for head-and-neck cance...

Purpose: Volumetric intensity-modulated arc therapy (RA) allows for rapid delivery of highly conformal dose distributions. In this study, planning and dosimetry of RAwere compared with conventional intensity-modulated radiation therapy (IMRT) plans of head-and-neck cancer patients. Materials and Methods: Computed tomography scans of 12 patients who had completed IMRT for advanced tumors of the ...

BACKGROUND.: Treatment planning for head and neck (H&N) cancer is complex due to the number of organs at risk (OAR) located near the planning treatment volume (PTV). Distant OAR must also be taken into consideration. Intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) are both common H&N treatment techniques with very different planning approaches. Alth...

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...

Background Treatment of patients with pelvic adenoid cystic carcinoma (ACC) remains a challenge owing to the rarity of the disease, the lack of data, and the relative radioresistance of these tumors. Case reports This case series presents the results of three patients with recurrent or inoperable pelvic ACC treated with intensity-modulated radiotherapy (IMRT) plus carbon ion (C12) boost. Pati...
