Histological and Molecular Study of HOXA11 Gene in Endometrial Carcinoma.

Background & Objective: Endometrial carcinoma (EC) is one of the most common cancers and the fourth most common cancer affecting females, mostly affecting postmenopausal women. EC originates from the endometrium and is further subdivided into two types that are estrogen dependent; type 1 and type 2 with different gene expression patterns. Materials & Methods: This research was carried out between December 2021 and August 2022 in the Laboratories of the College of Science/Department of Biology and the other local lab and PCR was employed to establish HOXA11 presence. The aims of the study were to reveal the histological alterations in malignant and benign tumors and normal endometrium and to examine the relationship between HOXA11 levels and clinicopathological parameters including stage, grade, muscle and lymph node invasion, and histological type. Results: The mean HOXA11 expression values were compared in cancer, benign, and control endometrial patients' groups. The mean HOXA11 expression level was the lowest in endometrial cancer patients; they had a mean of 0. 24±0. 03, those with benign endometrial tumors had the second lowest with a mean of 0. 94±0. 06, while the control patients had the highest mean expression with 1. 00±0. 07. The comparison of the HOXA11 expression between the endometrial cancer patients and the control group showed a statistically significant difference (P-value >0. 001), thus underlining its diagnostic value. Also, there was a significant difference in the HOXA11 expression means between patients with benign tumors and control patients (P-value = 0. 021). As for HOXA11, the mean expression was relatively lower in the patients with benign endometrial tumors, 0. 94±0. 06 as compared to the control group 1. 00±0. 07. In addition, the mean HOXA11 expression in endometrial cancer patients was 0. 24±0. 03 which was significantly (P-value >0. 001) less than that in benign endometrial tumor patients. Conclusion: These results stress the importance of HOXA11 expression as a diagnostic marker and its possible application in differential diagnosis between endometrial cancer and benign neoplasms and normal tissues.
