Abstract
OBJECTIVE To assess the role of histopathological and molecular features in predicting the risk of nodal metastases in apparent early-stage endometrial cancer patients undergoing sentinel node mapping. METHODS This is a prospective trial. Consecutive patients with apparent early-stage endometrial cancer, undergoing laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and sentinel node mapping, were enrolled. Histological and molecular features were used to predict the node positivity. RESULTS Charts of 223 apparent early-stage endometrial cancer patients were included in this study. Four (1.8%) patients were excluded from this study due to the lack of data about molecular features. Additionally, nine (4%) patients did not meet the inclusion criteria (due to the presence of peritoneal carcinomatosis or bulky nodes (the presence of p53 abnormality correlated with the presence of advanced stage disease (p<0.001)). The study population included 178 (84.8%) and 32 (15.2%) patients with endometrioid and non-endometrioid endometrial cancer, respectively. According to pathological uterine risk factors, 93 (44.3%), 45 (21.4%), 40 (19.1%), and 32 (15.2%) were classified as low, intermediate, intermediate-high, and high-risk, respectively. Using the surrogate molecular classification, 10 (4.8%), 42 (20%), 57 (27.1%), and 101 (48.1%) were included in the POLE mutated, p53 abnormal, MMRd/MSI-H, and NSMP, respectively. Overall, 41 (19.5%) patients were detected with positive nodes. Molecular features were not associated with the risk of having nodal metastases (OR 1.03, 95% CI 0.21 to 5.05, p=0.969 for POLE mutated; OR 0.788, 95% CI 0.32 to 1.98, p=0.602 for p53 abnormal; OR 1.14, 95% CI 0.53 to 2.42, p=0.733 for MMRd/MSI-H). At multivariable analysis, only deep myometrial invasion (OR 3.318, 95% CI 1.357 to 8.150, p=0.009) and lymphovascular space invasion (OR 6.584, 95% CI 2.663 to 16.279, p<0.001) correlated with the increased risk of positive nodes. CONCLUSION Our data suggest that molecular classification does not seem useful to tailor the need of nodal dissection in apparent early-stage endometrial cancer. p53 abnormality predicts the risk of having advanced disease at presentation. Further external validation is needed. CLINICAL TRIAL REGISTRATION NCT05793333.

Abstract
Endometrial cancer shows high histological and molecular heterogeneity. The POLE mutation is a significant molecular alteration in endometrial cancer, leading to the identification of a specific subtype known as POLE-mutated endometrial cancer. This subtype exhibits a high tumor mutation burden, abundant lymphocyte infiltration, and a favorable prognosis, making it a promising candidate for immune checkpoint inhibitor therapy. This paper presents a comprehensive review of the clinical and pathological characteristics, outcomes, treatment advancements, pathogenic POLE gene detection, and alternative testing methods for POLE-mutated endometrial cancer.

Abstract
BACKGROUND Endometrial cancers with more than one molecular feature-POLE mutations (POLEmut), mismatch repair protein deficiency (MMRd), p53 abnormality (p53abn)-are called 'multiple classifiers'. OBJECTIVE To describe our cohort of multiple classifiers and to report the results of a review on their incidence and the techniques used to identify them. METHODS Multiple classifiers identified at the European Institute of Oncology, Milan, between April 2019 and Decmber 2022, were included. Clinicopathological, molecular characteristics, and oncologic outcomes were summarized and compared between single and multiple classifiers sharing common features. Studies on molecular classification of endometrial cancer were searched in the PubMed Database to collect data on the incidence of multiple classifiers and the techniques used for classification. RESULTS Among 422 patients, 48 (11.4%) were multiple classifiers: 15 (3.6%) POLEmut-p53abn, 2 (0.5%) POLEmut-MMRd, 28 (6.6%) MMRd-p53abn, and 3 (0.7%) POLEmut-MMRd-p53abn. MMRd-p53abn and MMRd differed in histotype (non-endometrioid: 14.8% vs 2.0%, p=0.006), grade (high-grade: 55.6% vs 22.2%, p=0.001), and MMR proteins expression, whereas they differed from p53abn in histotype (non-endometrioid: 14.8% vs 50.0%, p=0.006). POLEmut-p53abn and POLEmut differed only in grade (high-grade: 66.7% vs 22.7%, p=0.008), while they differed from p53abn in age (56.1 vs 66.7 years, p=0.003), stage (advanced: 6.7% vs 53.4%, p=0.001), and histotype (non-endometrioid: 6.7% vs 50.0%, p=0.002). Two (7.1%) patients with MMRd-p53abn, 4 (4.0%) with MMRd, and 25 (34.3%) with p53abn had a recurrence. No recurrences were observed in POLEmut-p53abn and POLEmut. TP53 sequencing allowed the detection of additional 7 (18.9%) multiple classifiers with normal p53 immunostaining. The incidence of multiple classifiers ranged from 1.8% to 9.8% in 10 published studies including >100 patients. When only p53 immunohistochemistry was performed, the highest incidence was 3.9%. CONCLUSIONS The characteristics of POLEmut-p53abn resembled those of POLEmut, whereas MMRd-p53abn appeared to be intermediate between MMRd and p53abn. The high proportion of multiple classifiers may be related to the methods used for molecular classification, which included both p53 immunohistochemistry and TP53 sequencing.
