Aim: To investigate the efficacy and toxicity of hypofractionated stereotactic radiotherapy for treatment patients presenting with hepatocellular carcinoma (HCC) in a single institutional setting. Methods: Sixteen who presented solitary HCC, including two tumor thrombus portal veins, were treated or without transarterial chemoembolization. The criteria existence technical difficulties other ablation therapies, inoperable disease refusal to undergo surgery, staged as Grade A B according...
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...
This study aimed to assess the imaging appearances of focal liver reactions following stereotactic body radiotherapy (SBRT) for small hepatocellular carcinoma (HCC) and examine relationships between appearance baseline function. We retrospectively studied 50 lesions in 47 patients treated with SBRT (30-40 Gy 5 fractions) HCC, who were followed up more than 6 months. After SBRT, all underwent regular follow-ups blood tests dynamic CT scans. At a median follow-up 18.1 months (range 6.2-43.7...
To prospectively use long-scan-time computed tomography (CT) to visualize the trajectory of tumor movements or internal target volume.The study was approved by institutional review board. Written informed consent obtained from participants after and role procedures were explained fully. During planning stereotactic radiation therapy for 10 patients (nine men, one woman; mean age, 77 years; range, 69-89 years) with small lung tumors (mean volume, 9.0 cm3; 3.6-24.9 cm3), fluoroscopic imaging,...
