Relationship Between Dose and Local Control in Five-fraction Stereotactic Body Radiotherapy for Hepatocellular Carcinoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
aimTo retrospectively analyze the relationship between local control (LC) and the minimum dose covering 95% of the planning target volume (PTV D95%) in patients with hepatocellular carcinoma (HCC) treated with stereotactic body radiotherapy (SBRT). PATIENTS AND
methodsBetween May 2020 and March 2024, 72 HCC tumors in 59 patients were evaluated at Yokohama City University Medical Center. The prescribed dose ranged from 30-50 Gy in five fractions in accordance with the RTOG 1112 trial. However, PTV D95% was used for evaluation because of dose reductions near organs at risk.
resultsThe median follow-up period was 20 months. During this period, 13 patients died, and nine local recurrences were observed. The median PTV D95% was 38.9 Gy (range=10.6-48.5 Gy). The 1- and 2-year LC rates were 93.7% and 82.3%, respectively. Both univariate and multivariate analyses identified PTV D95% as a significant prognostic factor for LC [univariate: hazard ratio (HR)=0.882, 95% confidence interval (CI)=0.797-0.977,
conclusionPTV D95% was a significant prognostic factor for LC in patients with HCC treated with five-fraction SBRT. These findings suggest that PTV D95% ≥40 Gy should be considered as a cut-off dose to prevent recurrence.
