Abstract

<b><i>Objective:</i></b> Atypical endometrial hyperplasia (AH) is the neoplastic precursor more often associated with endometrial cancer (EC). Nowadays, 25–50% of patients subjected to hysterectomy for preoperative AH are diagnosed with EC at the final pathological analysis. Furthermore, there is no consensus on which preoperative AH patients would benefit from sentinel lymph node mapping. This study aimed to evaluate nodal assessment and preoperative cancer risk factors in preoperative AH patients undergoing nodal surgical staging. <b><i>Methods:</i></b> Patients undergoing surgical treatment for AH were retrospectively included in the analysis. Patients were divided into two groups (AH and EC groups) based on the final surgical pathology. The ESGO/ESTRO/ESP risk classification was used for EC cases. <b><i>Design:</i></b> This was a retrospective study. <b><i>Results:</i></b> Of the 207 AH patients treated, 152 cases met the inclusion criteria. Among preoperative AH patients with final EC diagnosis, 39 patients were in the low-risk group (25.7%), 8 in the intermediate-risk group (5.3%), 4 in high-intermediate (2.6%), and 3 patients were allocated in the high-risk group (2.0%). Fifty-four total patients underwent nodal surgical staging. Only one nodal micrometastasis (0.7%) was found at ultrastaging. Multivariate analysis showed abnormal uterine bleeding (AUB) (<i>p</i> = 0.01), hypertension (<i>p</i> &#x3c; 0.01), and endometrial thickness ≥20 mm (<i>p</i> = 0.02) statistically more represented in patients with EC at final surgical analysis. EC risk was 2.9 (95% CI: 1.29–6.48) in AUB, 2.7 (95% CI: 1.06–6.92) in hypertension, and 3.1 (95% CI: 1.19–7.97) in endometrial thickness ≥20 mm cases. <b><i>Limitations:</i></b> The present study has limitations inherent in its retrospective nature. <b><i>Conclusion:</i></b> The overall risk of nodal metastases in preoperative AH patients was low. Conversely, 9.9% of the preoperative AH patients belonged to the intermediate or high-risk group for EC at the final histological examination. Preoperative cancer risk factors would identify AH patients for whom nodal staging could be suggested.
