AI Article Synopsis
- The study aimed to assess the survival outcomes and identify risk factors for patients with hepatocellular carcinoma (HCC) treated using stereotactic body radiotherapy (SBRT).
- A total of 73 patients were analyzed, revealing high local control rates and 1, 3, and 5-year survival rates of 94.5%, 63.9%, and 45.5%, respectively.
- Key factors affecting prognosis included baseline modified albumin-bilirubin grades and BCLC stages, indicating that patients with better mALBI grades had a more favorable prognosis.
Article Abstract
Background/aim: This study was conducted to determine the prognosis and risk factors for survival in patients treated with stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC).
Patients And Methods: This retrospective study analyzed 73 patients who underwent SBRT for HCC at Nagasaki University Hospital from December 2012 to July 2019 and examined the relationship between baseline information and prognosis. The Kaplan-Meier analysis and log-rank test were used to estimate the survival rate. Cox regression analysis was performed to determine the factors associated with overall survival (OS) after SBRT.
Results: The 1- and 2-year local control rates were 98.6% and 89.9%, respectively. Survival rates at 1, 3, and 5 years were 94.5%, 63.9%, and 45.5%, respectively. In the univariate analysis, baseline modified albumin-bilirubin grade (mALBI grade) [2b/3, hazard ratio (HR)=2.762, p=0.001], tumor size (≥2 cm, HR=2.479, p=0.003), and Barcelona Clinic Liver Cancer stage (BCLC) (B/C, HR=3.284, p<0.001) were significantly associated with poor prognosis. In multivariate analysis, baseline mALBI grade (2b/3, HR=2.283, p=0.009) and BCLC stage (B/C, HR=2.330, p=0.013) were significantly associated with poor prognosis. Only three patients (4.1%) developed grade 3 adverse events related to SBRT.
Conclusion: SBRT is effective and safe in patients with HCC. The baseline mALBI grade is useful for predicting patient prognosis after SBRT. Patients with an mALBI grade of 1/2a are expected to have a better prognosis than patients with an mALBI grade of 2b/3.

Background A minority of patients receiving stereotactic body radiation therapy (SBRT) for non-small cell lung cancer (NSCLC) are not good responders. Radiomic features can be used to generate predictive algorithms and biomarkers that can determine treatment outcomes and stratify patients to their therapeutic options. This study investigated and attempted to validate the radiomic and clinical features obtained from early-stage and oligometastatic NSCLC patients who underwent SBRT, to predict local response.

Purpose: Transcranial magnetic stimulation (TMS) has emerged as a promising treatment for various neuropsychiatric conditions, including depression, obsessive-compulsive disorder, and Parkinson's disease. Recent research has focused on evaluating its effectiveness in treating patients with anorexia nervosa (AN). This systematic review and meta-analysis examined the impact of TMS on patients with AN and evaluated any potential adverse effects.

This study aimed to evaluate the recent trends in single-fraction conventional radiotherapy (CRT) as palliative treatment in Japan, using data from the National Database published by the Ministry of Health, Labor, and Welfare. Data from fiscal year (FY) 2014 to FY2022, specifically related to the utilization of single-fraction CRT, were analyzed. Multi-fraction CRT, stereotactic body radiotherapy (SBRT), intensity-modulated radiotherapy (IMRT), and brachytherapy were excluded.
