Abstract:

Objective: To explore the correlation between ProMisE molecular typing and lymph node metastasis and other clinical features in endometrial cancer. Methods: 74 patients with endometrial cancer who underwent surgical treatment at Cancer Hospital Affiliated of Dalian University of Technology from December 2014 to December 2018 were selected. Clinical data were collected and molecular typing was performed using the ProMisE method. The clinical characteristics of patients with different subtypes were compared, and the influencing factors of lymph node metastasis in endometrial cancer were analyzed. Results: Among 74 patients with endometrial carcinoma, 20 patients (27.0%) were mismatch repair defective, 2 patients (2.7%) were POLE mutant, 34 patients (46.0%) were p53 wild-type, and 18 patients (24.3%) were p53 mutated. There were statistically significant differences in lymph node metastasis (P=0.004), clinical stage (P=0.018), and pathological grading (P=0.036) among the four molecular subtypes of patients. Binary Logistic regression analysis revealed that p53 mutated (OR=27.669, 95%CI: 3.224-237.480, P=0.002) and muscle infiltration≥1/2 (OR=22.046,95%CI:4.185-116.146,P<0.001) as risk factors for lymph node metastasis. Conclusions: Molecular typing can provide an important reference for preoperative decision-making, that is, ProMisE molecular typing is performed on preoperative diagnostic uterine curettage specimens. If p53 mutant is found, the risk of lymph node metastasis is high and may need to be expanded intraoperatively.
