[OA-25] Diagnostic concordance of low-grade endometrial carcinoma between preoperative endometrial biopsy compared to hysterectomy specimen

The discordant histologic grade and subtype of endometrial carcinoma (EC) between the diagnosis of endometrial biopsy and hysterectomy specimen has an impact on patient management. This study aimed to compare the diagnosis of endometrial biopsy with hysterectomy specimen and to determine the histologic factors leading to the discordant grade and subtype. A retrospective study was conducted in 187 cases ...

[OA-09] Assessment of different cut-offs of equivocal HER2 IHC in breast cancer for HER2 ISH to reach appropriate sensitivity, AUC and reduction of ISH assay

The equivocal range of HER2 immunohistochemistry (IHC) is complete weak to moderate staining > 10% of breast cancer cells. This range has increased the numbers of HER2 in situ hybridisation (ISH) testing compared to the previous recommendations. ...
