About 40-60% of patients treated with post-operative radiotherapy for parotid cancer experience ipsilateral sensorineural hearing loss. Intensity-modulated radiotherapy (IMRT) can reduce radiation dose to the cochlea. COSTAR, a phase III trial, investigated the role of cochlear-sparing IMRT (CS-IMRT) in reducing hearing loss.
Randomized controlled study comparing simultaneous modulated accelerated radiotherapy versus simultaneous integrated boost intensity modulated radiotherapy in the treatment of locally advanced head and neck cancer.
Comparison of two fractionation schedules of intensity modulated radiotherapy (IMRT) for locally advanced head and neck cancer - simultaneous integrated boost (SIB-IMRT) and simultaneous modulated accelerated radiotherapy (SMART) boost in terms of toxicity and survival end-point measures.
Complete resection is the mainstay of treatment for thymoma. Even for advanced-stage thymoma with pleural dissemination, complete resection with extrapleural pneumonectomy may provide a favorable prognosis. Pleurectomy decortication, a lung-sparing surgery, has been preferably employed in recent years as an alternative surgical procedure for malignant pleural mesothelioma. However, little has been reported about pleurectomy decortication for other malignant tumors with pleural dissemination. Here, we presen...
Intensity modulated radiotherapy (IMRT) is used, where necessary, for bulky or complex-shaped, locally-advanced, non-small cell lung cancer (NSCLC). We evaluate our real-world experience with radical radiotherapy including concurrent chemoradiation (CCRT), and analyse the impact of IMRT on survival outcomes in patients with larger volume disease.
The purpose of this study was to present our comparison of the clinical outcome of patients with nasopharyngeal carcinoma (NPC) treated with whole-field intensity-modulated radiotherapy (whole-field-IMRT) or split-field-IMRT.
We evaluated postoperative mortality and complications after extrapleural pneumonectomy (EPP) and pleurectomy decortication (P/D) to better understand their effectiveness in malignant pleural mesothelioma (MPM).
Malignant pleural mesothelioma (MPM) is a rare disease and management of localized disease is controversial. Radiotherapy has been shown to be useful after extrapleural pneumonectomy (EPP), as well as with less aggressive surgery. As no reports of the treatment of this disease have ever been published from Israel, we report our experience with MPM and intensity-modulated radiotherapy (IMRT).
To evaluate the differences between conventional fractionated intensity-modulated radiotherapy (IMRT) and hypofractionated (HypoRT) volumetric modulated arc therapy (VMAT) in elderly women affected by early-stage breast cancer (BC) in terms of RT-related acute/late side effect.
For whole esophagus and T-shaped field radiotherapy using intensity modulated radiotherapy (IMRT) technique in advanced esophageal cancer, lower absorbed doses to lung and heart remains a challenge. The aim of this study was to investigate the dosimetric superiority in IMRT plans with jaw tracking technique for whole esophagus radiotherapy.
Radiotherapy (RT) is an effective treatment for breast cancer. The side effects of breast irradiation, including skin toxicity in the irradiation field, cause considerable discomfort. This study compared the severity of skin toxicity caused by image-guided RT (IGRT) and intensity-modulated RT (IMRT) combined with an electronic portal imaging device (EPID) in breast cancer. This study retrospectively analyzed 458 patients with breast cancer who had received RT. The patients were divided into two groups: 302 ...
Xerostomia is a debilitating side effect of radiotherapy for head and neck cancer. Combining surgical submandibular-gland transfer (SMGT) with intensity-modulated radiotherapy (IMRT) may provide greater protection of salivary function.
Systematic review and meta-analyses of intensity-modulated radiation therapy versus conventional two-dimensional and/or or three-dimensional radiotherapy in curative-intent management of head and neck squamous cell carcinoma.
Technological advancements in treatment planning and delivery have propelled the use of intensity-modulated radiation therapy (IMRT) in head and neck squamous cell carcinoma (HNSCC). This review compares IMRT with conventional two-dimensional (2D) and/or three-dimensional (3D) radiotherapy (RT) in curative-intent management of HNSCC.
Radiotherapy treatment planning of complex radiotherapy techniques, such as Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT), is a resource-intensive process requiring a high level of treatment planner intervention to ensure high plan quality. This can lead to variability in the quality of treatment plans and the efficiency in which plans are produced, depending on the skills and experience of the operator and available planning time. Within the last few years, there has b...
Chemoradiation with 5-fluorouracil and mitomycin remains the standard of care for squamous cell carcinoma (SCC) of the anal canal. A prolonged treatment time is associated with inferior disease-specific outcomes. Radiation Therapy Oncology Group trial 0529 demonstrated decreased toxicity and fewer treatment breaks with intensity-modulated radiotherapy (IMRT), but this has not been assessed in a randomized trial. Using data from the National Cancer Data Base (NCDB), this study evaluated the impact of IMRT on...
To analyze the long-term outcome and pattern of failure for patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT).
The flattening filter (FF) has traditionally been used to flatten beams or create uniform fields in conformal and intensity-modulated radiation therapy (IMRT) but reduces the dose rate. Many studies have confirmed improvement in delivery efficiency by removing the FF, also known as flattening filter free (FFF), especially for small field stereotactic body radiation therapy (SBRT); but it is unclear if large treatment fields still favor the FFF beam. We propose a novel, unified approach to quantify delivery ...
We present a particle swarm optimization (PSO)-based technique to create deliverable four-dimensional (4D=3D+time) intensity-modulated radiation therapy (IMRT) plans for lung stereotactic body radiotherapy (SBRT). The 4D planning concept uses respiratory motion as an additional degree of freedom to achieve further sparing of organs at risk (OARs). The 4D-IMRT plan involves the delivery of an order of magnitude more IMRT apertures (~15,000 - 20,000), with potentially large inter-aperture variations in the de...
The purpose of this study was to evaluate the dosimetric variation among six non-beam-matched Varian linacs using different techniques for the same plans. Six non-beam-matched Varian machines, comprising two Clinac iX, two 600 C/D (Unique), and two True Beam Tx photon 6 MV X-ray devices were acquired. Sixty patients with of head and neck (H&N; 30) and pelvic (30) treatment sites were chosen. For all 60 patients, three-dimensional conformal radiotherapy (3DCRT), intensity-modulated radiotherapy (IMRT), and ...
Motion and uncertainty in radiotherapy is traditionally handled via margins. The clinical target volume (CTV) is expanded to a larger planning target volume (PTV), which is irradiated to the prescribed dose. However, the PTV concept has several limitations, especially in proton therapy. Therefore, robust and probabilistic optimization methods have been developed that directly incorporate motion and uncertainty into treatment plan optimization for intensity modulated radiotherapy (IMRT) and intensity modulat...
Background The aim of the study was to evaluate and compare four different external beam radiotherapy techniques of accelerated partial breast irradiation (APBI) considering target coverage, dose to organs at risk and overall plan quality. The investigated techniques were three dimensional conformal radiotherapy (3D-CRT), "step and shoot" (SS) and "sliding window" (SW) intensity-modulated radiotherapy (IMRT), intensity-modulated arc therapy (RA). Patients and methods CT scans of 40 APBI patients were select...
Intensity-modulated radiotherapy (IMRT) is widely used in the treatment of Head and Neck Cancers (HNC). There is not enough evidence to suggest that some radiation oncologists (RO) are associated with better outcomes in HNC patients. We conducted a cross-sectional analysis to evaluate the effect of radiation oncologists' characteristics on outcomes in HNC patients treated with IMRT.
The standard of care trimodality therapy for resectable locally advanced esophageal adenocarcinoma is complex and necessitates multidisciplinary care and expertise. In this work, it is hypothesized that facility clinical volume and utilization of intensity-modulated radiotherapy (IMRT) may influence outcomes. The National Cancer Data Base was queried for patients with cT1-4-N0-3 M0 esophageal adenocarcinoma undergoing trimodality therapy from 2004 to 2013 (n = 2445). All patients received chemoradiation f...
The purpose of this study was to investigate whether the metabolic tumor volume (MTV) of head and neck primary tumors may be a significant prognostic factor for feeding tube (FT) use and FT dependence. Seventy-nine patients with evaluable primary tumors, pre-therapy FDG-PET scans, treated with definitive intensity-modulated radiotherapy (IMRT) (± concurrent chemotherapy) for head and neck mucosal cancers were included. MTV was quantified and recorded for the primary lesion using a minimum standardized up...
For patients who require postoperative radiotherapy after endoscopic resection of skull base tumors, proton therapy with pencil beam scanning (PBS) may allow sparing of normal tissue compared to intensity-modulated photon radiation (IMRT). We compared PBS and IMRT radiation plans in the preoperative and postoperative settings for two patients with advanced skull base tumors following endoscopic resection. The benefits of PBS over IMRT appear greater in the postoperative setting following endoscopic resectio...
