OBJECTIVES/HYPOTHESIS To review toxicity and outcomes in patients with head and neck cancer treated with simultaneous integrated boost-intensity-modulated radiotherapy (SIB-IMRT). STUDY DESIGN Review of experience with the SIB-IMRT technique. METHODS Fifty patients were treated with the SIB-IMRT technique. Two possible schedules of radiation therapy (RT) were used: SIB 70 (70/60/54 in 33 fr...
PURPOSE The aim of this retrospective cohort study was to assess treatment outcome, and acute pulmonary and esophageal toxicity using intensity modulated (sequential/concurrent chemo)radiotherapy (IMRT) in locally advanced stage III non-small cell lung cancer (NSCLC). METHODS AND MATERIALS Eighty-six patients with advanced stage NSCLC, treated with either IMRT only (66 Gy) or combined with (s...
OBJECTIVE To investigate the feasibility of using intensity-modulated radiotherapy (IMRT) with reduced, high-dose target volumes for nasopharyngeal carcinoma (NPC). METHODS The first 57 patients (admitted from October 2005 to May 2008) were treated with large-target-volume IMRT (LV-IMRT). For the LV-IMRT group, the CTV at 70 Gy (CTV70) was delineated as the gross target volume (GTV) plus 7mm,...
Herein, we present a rare complication of radio-chemotherapy. A young man presented with loss of urine from the posterior perineum that showed a massive disappearance. He underwent Hartmann procedure for rectal neoplasia, afterwards treated with intensity-modulated radiotherapy (IMRT) (until 67 Gy) and chemotherapy with FOLFOX protocol (Leucoverin calcium, Fluorouracil, Oxaliplatin).
Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...
BACKGROUND To compare the dosimetric advantage of three different intensity-modulated radiation therapy (IMRT) plans to a three dimensional (3D) conventional radiation treatment for anal cancer with regards to organs-at-risk (OAR) avoidance, including iliac bone marrow. METHODS Five patients with T1-3 N0-1 anal cancer and five with T4 and/or N2-3 tumors were selected. Clinical tumor volume (C...
BACKGROUND While IMRT is widely used in treating complex oncological cases in adults, it is not commonly used in pediatric radiation oncology for a variety of reasons. This report evaluates our 9 year experience using stereotactic-guided, inverse planned intensity-modulated radiotherapy (IMRT) in children and adolescents in the context of the current literature. METHODS Between 1999 and 2008 ...
BACKGROUND/AIM The purpose of the present study was to compare intensity-modulated radiation therapy (IMRT) plan with (Bone Marrow Sparing (BMS) - IMRT) or without (normal-IMRT) an intention of avoiding bone marrow in order to minimize treatment-related toxicity. PATIENTS AND METHODS Computed tomography (CT) images of 10 consecutive postoperative cervical cancer patients were used. All patien...
BACKGROUND Image-guided (IG) intensity-modulated radiotherapy (IMRT) enables maximal tumor margin reduction for the sparing of organs at risk (OARs) when used to treat locally advanced non-small cell lung cancer (NSCLC) with definitive chemo-radiation. It also allows for the incorporation of stereotactic ablative radiotherapy (SABR) into the treatment regimen. Here, we describe our initial expe...
PURPOSE Standard treatment for early-stage endometrial cancer involves surgery (when possible) followed by brachytherapy or external-beam radiotherapy (EBRT) for high-risk tumors. EBRT is not without toxicity, meaning that it could be difficult to complete for elderly patients, who typically have decreased reserve and resistance to stressors. PATIENTS AND METHODS Patients aged 70 and over tre...
