Comparison of Intrafraction Variation of Dose-volume Parameters in Hybrid Brachytherapy for Carcinoma Cervix.

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
Purpose: The present study aimed to compare the dosimetric parameters for a fractional re-imaging approach using computed tomographic (CT) scans before the first and third fractions with hybrid brachytherapy for carcinoma cervix patients. Materials and Methods: Patients with cervical carcinoma who received radical chemoradiation and hybrid brachytherapy were prospectively included for the analysis. The first fraction was delivered on day 1 after applicator insertion and the second and third fractions were delivered on day 2, 6 h apart. Two plans were created for each patient using CT-based planning, one before the first fraction (Plan 1) and the other before the third fraction (Plan 2). The dose prescribed was 7 Gy per fraction to high-risk clinical target volume (HRCTV). The dosimetric parameters compared between the two plans were D90 HRCTV, D98 IRCTV, TRAK, D0.1cc, and D2cc to the bladder, rectum, sigmoid, and dose to the ICRU 89 radiation therapy (RV) point, respectively. Results: Fifteen patients were included for the analysis. The mean HRCTV volume was 31 cc. The mean D90 HRCTV was 87.86 Gy EQD2 for Plan 1 versus 84.64 Gy EQD2 for Plan 2, respectively ( Conclusion: In carcinoma cervix patients undergoing hybrid brachytherapy in a single application multiple fraction approach, there can be significant variations in rectum doses. These results indicate that fractional re-imaging is necessary to optimize the plan and spare organ-at-risk.
