Abstract

Objective: Visual disturbances that can heal after a complete resection of orbital meningiomas are only about 2.9%. Grading and expression of the progesterone receptor (PR) in orbital meningiomas, according to World Health Organization (WHO) is a useful predictive value of recurrence in the treatment management of orbital meningiomas. This study aims to determine the relationship of PR expression on the grading of orbital meningiomas as tumour prognostic factors. Methods: This cross-sectional observational analysis observed 44 orbital meningioma in Cicendo Eye Hospital Bandung and Hasan Sadikin Hospital between 2017-2020. We performed of mRNA PR with RT-qPCR technique and calculation with the 2∆∆Ct formula. Statistical analysis used the Kruskal-Wallis Test, followed by the Mann-Whitney post hoc test with p<0.005. Results: Relative expression of mRNA PR in meningioma orbita grade I to grade III decreased significantly the expression of relative mRNA PR at grade I, II, III of 21.69±44.35, 20.39±26.30 and 1.25±0.85, with Kruskal-Wallis test, p =0.007. Mann Whitney’s test results showed relative mRNA PR expression between grades I and II not different (p = 0.055), relative expression mRNA PR between grades I and III differed significantly (p = 0.024), and relative expression mRNA PR between grades I and III was not different (p = 0.638). Conclusion: mRNA PR expression is viable for prognostic value, predicting recurrence and implementing more effective management of subsequent therapy, it must be combined with other markers to determine the nature of the orbital meningioma.
