Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
High upgrading rates of Gleason score 6 to 7 carcinomas between biopsy and radical prostatectomy specimens may be produced by change of fused glands of pattern 3 to pattern 4. Therefore, inter-observer reproducibility of fused and non-fused glands in biopsy specimens was analysed. Images of H&E stained slides of glands of carcinomas with Gleason score 6 and 7 (3+4) with and without glandular fusions with different lens magnification were analysed by 4 specialized genitourinary pathologists and 3 non-specialized pathologists. The definition of glandular fusion was a complete lack of any stromal fibres between a minimum of two glands and only one line of nuclei within the area of fusion. Overall agreement and interobserver reproducibility of fused versus non-fused glands of non- and uro-pathologically specialized pathologists were lower in lens magnification of 50× in contrast to 200×. The inter-observer reproducibility of fused glands by specialized observer was higher than that of nonspecialized pathologists. The results support the importance of strict but practicable criteria for the diagnosis of fused tumor glands in order to decrease the interobserver variability of Gleason scores, particularly in nonspecialised pathologists. © Arányi Lajos Foundation 2011.
