Is routine frozen section analysis necessary in patients with non-endometrioid cancer or grade 3 endometrioid cancer?
Article in International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo explore the accuracy related to type and subtype between frozen section (FS) results and final pathology results in patients with endometrial cancer and to suggest whether it should be routinely performed.
methodsRetrospective data were collected from 184 patients with endometrial cancer who underwent surgery at a single center (January 2014-December 2018). FS results were compared with the final pathology results with respect to histotype, tumor grade, and depth of invasion to define the accuracy of FS analysis.
resultsFrozen section analysis was performed in 141 (76.6%) patients. The accuracy rates and κ values between the FS and final pathology results with respect to histotype, tumor grade, and depth of invasion were 87.23%, 81.15%, and 98.2% and 0.41, 0.7, and 0.9, respectively (P < 0.001). Among the 18 patients with preoperative non-endometrioid cancer (non-EC), six underwent FS analysis, and final pathology confirmed EC in three, of whom 75% were detected by FS analysis. Eight of 19 patients with preoperative grade 3 EC underwent FS analysis and the accuracy rate was 87.5%.
conclusionIntraoperative FS analysis is a reliable method that can help intraoperative decision making. It should be performed routinely in patients with non-EC and grade 3 EC.
