Since 2005, we have treated hepatocellular carcinoma (HCC) with stereotactic body radiotherapy (SBRT) uniformly at two dose levels, according to baseline liver function and normal dose. We retrospectively examined the outcomes for these patients.Between 2005 2012, 221 HCC patients were SBRT. Eligibility criteria SBRT included a single (either solitary or recurrent) lesion; unfeasible, difficult refusal undergo other surgery percutaneous ablative therapies; Child-Pugh Classification (CPC) A...
Abstract Aim To prospectively evaluate the efficacy and safety of stereotactic body radiotherapy (SBRT) for patients with previously untreated solitary primary hepatocellular carcinoma (HCC). Methods The main eligibility criteria included following: (1) HCC; (2) no prior treatment (3) Child–Turcotte–Pugh score seven or less; (4) unsuitability refusal surgery radiofrequency ablation (RFA). prescribed dose SBRT was 40 Gy in five fractions. endpoint 3‐year overall survival (OS); secondary...
The purpose of this study was to investigate swallowing function older adults with lowered hyoid bone position. A total 60 (23 males and 37 females, mean age: 70.1 years) no diagnosed dysphagia participated in the study. Participants were divided into two groups (High Low group) based on anterior point (H) respect line connecting most inferior corpus third cervical vertebra (C3) Menton (Me). Swallowing measured using Repetitive Saliva Swallow Test (RSST), Eating Assessment Tool (EAT-10),...
The aim of this study was to investigate significant clinical, tumour-related and dosimetric factors among patients with grade 0-1, 2 3 radiation pneumonitis (RP) after stereotactic body radiotherapy (SBRT) for lung tumours.Patients (n=128) a total 133 tumours treated SBRT 50 Gy in 5 fractions were analysed. RP graded according the Common Terminology Criteria Adverse Events v.3.0. Significant identified by univariate multivariate analyses. Threshold dose-volume histograms (DVHs) constructed...
To better define clinically relevant non-classic radiation-induced liver disease (RILD) following stereotactic body radiotherapy (SBRT) in patients with small hepatocellular carcinoma (HCC).We retrospectively evaluated the influence of acute toxicities on fatal hepatic failure HCC treated SBRT. Between April 2006 and February 2012, 194 were Among them, followed up for more than 6 months eligible. Laboratory results Child-Pugh (CP) scores obtained before treatment at monthly follow-up visits....
We previously reported that the local control of pulmonary metastases from colorectal cancer (CRC) following stereotactic body radiotherapy (SBRT) with moderate prescription dose was relatively worse. investigated treatment outcomes and toxicities patients oligometastases CRC treated by SBRT using risk-adapted, very high- convergent-dose regimens. Among referred for August 2011 to January 2015, those were extracted who had liver or CRC, they a total 50-60 Gy in five fractions prescribed 60%...
Abstract Purpose In patient‐specific quality assurance (QA) for static beam intensity‐modulated radiation therapy (IMRT), machine‐learning‐based dose analysis methods have been developed to identify the cause of an error as alternative gamma analysis. Although these new revealed that can be identified by analyzing distribution obtained from two‐dimensional detector, they not extended volumetric‐modulated arc (VMAT) QA. this study, we propose a deep learning approach detect various types...
The purpose of this study is to evaluate the CT appearances tumor responses following hypofractionated stereotactic ablative body radiotherapy for small hypervascular hepatocellular carcinomas (HCCs) and assess relationship between local control.Among 277 HCC tumors treated with (35 or 40 Gy per five fractions), we selected enhanced lesions on arterial phase performed before radiotherapy. Radiographic findings after were evaluated during a 2-year follow-up period modified Response Evaluation...
