Treatment Planning Comparison of Gantry-based and Fixed Beams for the Treatment of Liver Tumors With Carbon Ion Therapy.

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/
aimThis study aimed to compare the use of a rotating gantry in liver tumor carbon-ion radiotherapy using of a fixed-port for treatment planning. MATERIALS AND
methodsThirty patients with liver tumors were analyzed. Three treatment plans were developed for each case: one with a rotating gantry with a 360° angle, one with fixed ports of 0° and 90° with a ±20° couch rolling setting, and one with fixed ports of 45° and 90° with a ±20° couch rolling setting. The dose-volume histogram parameters of the clinical target volume (CTV) and organs at risk (OARs) for each treatment plan were compared.
resultsSignificant differences in the volume of the liver-gross tumor volume (GTV) of normal liver irradiated with 5 Gy to 15 Gy were found between the gantry treatment plans and fixed-port treatment plans. There were no significant differences in the OARs, except for the CTV and liver GTV, between the gantry and fixed-port treatment plans.
conclusionThe study results support the potential of using a rotating gantry to reduce liver doses, especially in the low-to-medium dose range, while maintaining target and OAR doses except for the liver. A rotating gantry could be especially useful in cases in which the relationship between the tumor and OAR is complicated by location.
