PURPOSE Proteomic profiling of patients undergoing intensity-modulated radiotherapy (IMRT) for prostate cancer can identify unique biomarkers that reflect acute toxicity in normal tissues. Our objectives were to measure inflammatory cytokine proteins during IMRT and assess the variability of individual proteomic signatures. EXPERIMENTAL DESIGN Forty-two patients with intermediate-risk prostat...

AIM This study was designed to evaluate the efficacy and toxicities of concomitant boost intensity-modulated radiation therapy (IMRT) along with capecitabine and oxaliplatin, followed by a cycle of Xelox, in neoadjuvant course for locally advanced rectal cancer. MATERIALS AND METHODS Patients with histologically confirmed, newly diagnosed, locally advanced rectal adenocarcinoma (cT3-T4 and/or...

PURPOSE To compare, in a national population-based study, severe genitourinary (GU) and gastrointestinal (GI) toxicity in patients with prostate cancer who were treated with radical intensity modulated radiation therapy (IMRT) or 3-dimensional conformal radiation therapy (3D-CRT). METHODS AND MATERIALS Patients treated with IMRT (n=6933) or 3D-CRT (n=16,289) between January 1, 2010 and Decemb...

OBJECTIVES/HYPOTHESIS To investigate the impact of treatment modality and radiation technique on oncologic outcomes and toxicity of patients with locally advanced oropharyngeal cancer (OPC). STUDY DESIGN Retrospective analysis of outcomes and toxicity. METHODS Between 2000 and 2011, 204 consecutive patients with locally advanced OPC were treated with definitive (chemo)radiotherapy using 3-d...

INTRODUCTION We evaluated single institution toxicity outcomes after post-prostatectomy radiotherapy (PPRT) via image-guided intensity-modulated radiation therapy (IG-IMRT) with implanted fiducial markers following national eviQ guidelines, for which late toxicity outcomes have not been published. METHODS Prospectively collected toxicity data were retrospectively reviewed for 293 men who unde...

Study Objective. To evaluate the space creation, maintenance and absorption of an absorbable hydrogel injected into the perirectal space of patients prior to undergoing prostate radiotherapy. Design. CT or MR imaging performed before hydrogel application (Baseline), one week after hydrogel application, following 8 weeks of IMRT (78Gy total) and then again 6 months following implantation. Settin...

BACKGROUND The aim of this study was to describe the effect of pretreatment prostate volume on urinary quality of life after intensity-modulated radiation therapy (IMRT) for clinically localized prostate cancer. METHODS A total of 368 men treated with prostate IMRT (77.4-81 Gy) were stratified into three gland volume groups, ie, <30 g (group 1), 30-60 g (group 2), and >60 g (group 3). Post-IM...

BACKGROUND Owing to highly conformed dose distribution, intensity modulated radiation therapy (IMRT) has the potential to improve treatment results of radiotherapy (RT). Postoperative RT is a standard adjuvant treatment in conservative treatment of breast cancer (BC). The aim of this review is to analyze available evidence from randomized controlled trials (RCTs) on IMRT in BC, particularly in ...

We compared treatment outcomes in patients with stage II nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT) or two-dimensional conventional radiotherapy (2D-CRT). Stage II (2010 UICC/AJCC staging system) NPC patients treated with IMRT (n = 178) or 2D-CRT (n = 73) between January 2007 and December 2014 were retrospectively analyzed. Patients were matched using th...

OBJECTIVES Long-term locoregional control following intensity-modulated radiotherapy (IMRT) for locally advanced squamous cell carcinoma of the head-and-neck (SCCHN) remains challenging. This study aimed to assess the efficacy and toxicity of IMRT with and without chemotherapy or surgery in locally advanced SCCHN. MATERIALS AND METHODS Between January 2007 and January 2011, 61 patients with l...
