    Abstract:
    We compared the efficacy of endometrial cancer neoadjuvant treatment in 38 patients receiving nonsteroid (letrozol, anastrozol) or steroid (ekzemestan) aromatase inhibitors and 12 patients receiving metformin. The changes in glucose metabolism were revealed in 26.3% of patients treated with aromatase inhibitors and 16.7% of patients treated with metformin. However, comparison of endometrial thickness (M-echo signal) data, postoperative data on favorable differentiation grade changes rate and proliferative activity (Ki-67 expression) revealed the superiority of 2-4 weeks aromatase inhibitors course in comparison with 2-9 (average 5.3 +/- 0.7) weeks metformin treatment.
