PURPOSE In this study, we retrospectively investigated the prevalence of arterioportal (AP) shunts in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) and evaluated the changes in AP shunts after chemoembolization followed by external beam radiation therapy (EBRT). MATERIALS AND METHODS We analyzed 54 HCC patients with PVTT who were treated with chemoembolizati...
OBJECTIVE To characterize complications of prostate cancer therapy and operative management in patients referred to our institution for surgical intervention. MATERIALS AND METHODS Data was abstracted from a retrospectively collected single surgeon database at a large tertiary care referral-based medical center. Variables included age, prostate cancer therapy, complication(s) and their manage...
Introduction The effects of ionising radiation on cells are complex and include cell apoptosis, cell swelling and cell lysis, all of which affect the cellular density. The aim of this study was to investigate if the apparent diffusion coefficient (ADC) changed before and after external beam radiotherapy (EBRT) in response to these effects using similar acquisition techniques to studies that hav...
AIM The aim of the present study was to evaluate changes in thyroid function in patients with head and neck cancer treated with external beam radiotherapy (EBRT). MATERIALS AND METHODS This prospective study was conducted on ninety patients with non-thyroid head and neck cancer who were referred to the department of radiotherapy. Thyroid function tests were conducted before, midway during and...
PURPOSE To report our experience treating soft tissue sarcoma (STS) with high dose rate brachytherapy alone (HBRT) or in combination with external beam radiotherapy (EBRT) in pediatric patients. METHODS AND MATERIALS Eighteen patients, median age 11 years (range 2 - 16 years) with grade 2-3 STS were treated with HBRT using Ir-192 in a interstitial (n = 14) or intracavitary implant (n = 4). Ei...
PURPOSE Stereotactic body radiotherapy (SBRT) is commonly used to treat unresectable lung nodules. Given its relative safety and effective local control, SBRT has also been used to treat recurrent lung nodules after high-dose external beam radiation (EBRT) to the lung. The toxicity of such treatment is unknown. METHODS AND MATERIALS Between 2006 and 2012, 18 subjects at the Mayo Clinic with 2...
Our goal was to determine the clinical treatment response following radiation administered with or without chemotherapy for locally advanced cervical cancers in Honduras. This is a retrospective study of patients treated with either concurrent chemoradiation (CCRT) or external beam radiation therapy (EBRT) alone at a hospital in Tegucigalpa, Honduras. 70 Gy of EBRT to the pelvis was given in al...
The purpose of this study was to report the outcomes of high-dose-rate (HDR) brachytherapy and hypofractionated external beam radiotherapy (EBRT) combined with long-term androgen deprivation therapy (ADT) for National Comprehensive Cancer Network (NCCN) criteria-defined high-risk (HR) and very high-risk (VHR) prostate cancer. Data from 178 HR (n = 96, 54%) and VHR (n = 82, 46%) prostate cancer ...
Normal tissue toxicity is an important consideration in the continued development of more effective external beam radiotherapy (EBRT) regimens for head and neck tumors. The ability to detect EBRT-induced changes in mandibular bone vascularity represents a crucial step in decreasing potential toxicity. To date, no imaging modality has been shown to detect changes in bone vascularity in real time...
The maintenance of satisfactory quality of life is major concern in majority of patients who elect treatment for localized prostate cancer. We conducted a cross-sectional study to determine sexual function after radical prostatectomy (RP) and external beam radiotherapy (EBRT). Study population consisted of series of 57 patients with early-stage adenocarcinoma of the prostate, treated in our ins...
