Evaluation of BEBIG HDR (60)Co system for non-invasive image-guided breast brachytherapy.
Article in Journal of contemporary brachytherapy, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeHDR (60)Co system has recently been developed and utilized for brachytherapy in many countries outside of the U.S. as an alternative to (192)Ir. In addition, the AccuBoost(®) technique has been demonstrated to be a successful non-invasive image-guided breast brachytherapy treatment option. The goal of this project is to evaluate the possibility of utilizing the BEBIG HDR (60)Co system for AccuBoost treatment. These evaluations are performed with Monte Carlo (MC) simulation technique. MATERIAL AND
methodsIn this project, the MC calculated dose distributions from HDR (60)Co for various breast sizes have been compared with the simulated data using an HDR (192)Ir source. These calculations were performed using the MCNP5 code. The initial calculations were made with the same applicator dimensions as the ones used with the HDR (192)Ir system (referred here after as standard applicator). The activity of the (60)Co source was selected such that the dose at the center of the breast would be the same as the values from the (192)Ir source. Then, the applicator wall-thickness for the HDR (60)Co system was increased to diminish skin dose to levels received when using the HDR (192)Ir system. With this geometry, dose values to the chest wall and the skin were evaluated. Finally, the impact of a conical attenuator with the modified applicator for the HDR (60)Co system was analyzed.
resultsThese investigations demonstrated that loading the (60)Co sources inside the thick-walled applicators created similar dose distributions to those of the (192)Ir source in the standard applicators. However, dose to the chest wall and breast skin with (60)Co source was reduced using the thick-walled applicators relative to the standard applicators. The applicators with conical attenuator reduced the skin dose for both source types.
conclusionsThe AccuBoost treatment can be performed with the (60)Co source and thick-wall applicators instead of (192)Ir with standard applicators.
