Background: E-cadherin is a cell adhesion molecule, its downregulation is associated with poorly differentiated tumors in many organs, and its loss is associated with adverse behavior of many tumors. Objectives: This study aims to find a correlation between E-cadherin status, the Grade Group, and the modified Gleason score in core biopsies obtained from prostatic carcinoma. Materials and Methods: This study is a retrospective and prospective cross-sectional study that was conducted on (50) paraffin blocks obtained from core biopsies of prostatic carcinoma. E-cadherin status was correlated with the Grade Group and the modified Gleason score. The E-cadherin staining pattern was also examined for its correlation with perineural invasion. Chi-square was used to determine the correlation between E-cadherin staining pattern on the one hand and the modified Gleason score, Grade Group, and perineural invasion on the other hand and P < 0.5% was considered as significant. Results: Only six patients (12%) fall in Grade Group 1 and according to the modified Gleason score, most patients had high scores. Regarding E-cadherin expression, 24 cases (48%) had aberrant E-cadherin expression, while the rest 26 cases (52%) had a complete strong membranous expression. Statistically, there was a significant correlation between aberrant E-cadherin expression and increasing grade according to the modified Gleason score and Grade Group with P values of 0.032% and 0.022%, respectively. In 24 patients (48%), perineural invasion was detected half of them had aberrant E-cadherin expression which was statistically notsignificant when both the parameters (perineural invasion and aberrant E-cadherin expression) are tested against the modified Gleason score and the Grade Group (P = 0.71%). Conclusion: Aberrant E-cadherin expression is associated with increasing modified Gleason score and Grade Group but has no significant correlation with perineural invasion.
