Effectiveness of tomotherapy vs linear sccelerator image-guided intensity-modulated radiotherapy for localized pharyngeal cancer treated with definitive concurrent chemoradiotherapy: a Taiwanese population-based propensity score-matched analysis.
This study used a population-based propensity score (PS)-matched analysis to compare the effectiveness of tomotherapy-based image-guided intensity-modulated radiotherapy (referred to as T-IMRT) with that of linear accelerator based (referred to as L-IMRT) for clinically localized pharyngeal cancer (LPC, divided into nasopharyngeal cancer and non-nasopharyngeal cancer) with definitive concurrent chemoradiotherapy (CCRT).
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 ...
To assess the feasibility and efficacy of intensity-modulated radiation implemented with helical tomotherapy image-guided with daily megavoltage computed tomography for head and neck cancer.
To assess the extents of pelvic floor descent both during the maximal straining phase and the defecation phase in healthy volunteers and in patients with pelvic floor disorders, studied with MR defecography (MRD), and to define specific threshold values for pelvic floor descent during the defecation phase.
Patient immobilization systems are used to establish a reproducible patient position relative to the couch. In this study, the impact of conventional lok-bars for CT-simulation (CIVCO-bar) and treatment (iBEAM-bar) were compared with a novel lok-bar (mHM-bar) in tomotherapy.
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.
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 ...
A prospective clinical trial was conducted for patients undergoing cardiac sparing (CS) whole lung irradiation (WLI) using IMRT. The 3 trial aims were: 1) To demonstrate the feasibility of CS IMRT with real time central quality control; 2) To determine the dosimetric advantages of WLI using IMRT compared to standard antero-posterior (AP) techniques; and 3) To determine acute tolerance and short-term efficacy after a protocol mandated minimum 2 year follow up for all patients.
Pelvic angiography with transcatheter arterial embolization (TAE) is an established intervention for management of pelvic arterial hemorrhage. This study analyzes complication rates after angiography among patients with pelvic trauma treated in the context of a multidisciplinary institutional pelvic fracture protocol.
Dislocated pelvic fractures which require surgical repair are usually operated on via open surgery. Approach-related morbidity is reported with a frequency of up to 30%. The aim of this anatomical study was to prove the feasibility of endoscopic visualisation of the relevant anatomical structures in pelvic surgery and to perform completely endoscopic plate osteosynthesis of the acetabulum with available standard laparoscopic instruments.
Cardiac sparing whole lung (WL IMRT) has been shown to improve cardiac protection and lung volume dose coverage compared to standard anteroposterior techniques. This dosimetry study had 2 aims: 1). To determine the dosimetric advantages of a modified WL IMRT (M-WL IMRT) technique designed to reduce radiation exposure to the thyroid gland and breast tissues compared to the standard WL IMRT (S-WL IMRT) and 2). To determine the dosimetric advantages of M-WL IMRT and dosimetrically matched abdomen/flank RT fiel...
The objective of this study was to evaluate the outcomes of vaginal pessaries in managing symptomatic pelvic organ prolapse (POP) in a low-income setting.
Determine the feasibility of oophorectomy at the time of vaginal hysterectomy in patients with pelvic organ prolapse and define prognostic factors and perioperative morbidity associated with the procedure.
Over the past 20 years, feasibility of laparoscopic approaches has been validated in gynecologic surgery. This procedure has specific challenges due its longer learning curve and the limits imposed by the technique. For the surgical treatment of recurrent pelvic cancers or locally advanced tumors, open surgery remains the gold standard for most surgical teams. Robotic assistance could be an interesting alternative. The aim of this study is to present our department's robotic surgical procedures in this spec...
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...
To examine the feasibility of implementing a standardized, clinically relevant genitourinary examination for both men and women and to identify physical examination findings characteristic of urological chronic pelvic pain syndromes (UCPPS).
About 5- 15 % of patients with concussion experience persistent post-concussion symptoms (PCS) longer than 3 months post-injury.
Pelvic exenteration (PE) for locally advanced pelvic malignancy requires a multi-disciplinary approach and is associated with significant morbidity. Urinary reconstruction forms a major component of this procedure. The aim of the study is to review the urological outcomes following PE in a newly established pelvic oncology unit, to compare with those following radical cystectomy (RC) for bladder cancer.
Conventional techniques (3D-CRT) for craniospinal irradiation (CSI) are still widely used. Modern techniques (IMRT, VMAT, TomoTherapy, proton pencil beam scanning [PBS]) are applied in a limited number of centers. For a 14-year-old patient, we aimed to compare dose distributions of five CSI techniques applied across Europe and generated according to the participating institute protocols, therefore representing daily practice.
To compare dynamic magnetic resonance imaging (dMRI) defecography phase findings with physical examination (PE) grading in the evaluation of pelvic organ prolapse (POP).
The aim of this study was to investigate knowledge and demographic factors associated with a lack of knowledge proficiency about urinary incontinence (UI) and pelvic organ prolapse (POP) among pregnant and postpartum women.
Women often develop pelvic floor dysfunction due to damage to the pelvic musculature during childbirth; however, the effect on pelvic floor nerves function is less understood. This study used adult rabbits to evaluate the electrophysiological and histological characteristics of the bulbospongiosus (Bsn) and pubococcygeus nerves (Pcn) in multiparity.
To assess the feasibility of using an integrated multimodal data collection strategy to characterize the post-intensive care syndrome (PICS).
The aim of study was to investigate opportunities of local phlebectomy in the elimination of isolated pelvic-perineal reflux (PPR), as well as to determine feasibility of endovascular embolization of the tributaries of internal iliac veins in PPR. Clinical trial no. NCT01598051.
Advances in technology have expanded the use of intensity-modulated radiotherapy (IMRT). The goal of this study was to investigate trends in the utilization of IMRT for rectal cancer (RC) in USA.
