Introduction:
This study analyzed and discussed the characteristics of peripheral blood lymphocytes (PBLs) in patients with endometrial carcinoma (EC) to explore the PBLs' clinical application value.
Methods:
This single-center case‒control study analyzed the clinical data of patients with EC and uterine fibroids who underwent surgery at the First Affiliated Hospital of Chongqing Medical University between October 2018 and October 2023 retrospectively. The Center for Clinical Molecular Medical Detection of our hospital performed PBLs detection using flow cytometry, and recorded the detection results in the electronic medical records system. Between-group and subgroup comparisons of PBLs in patients with EC were analyzed using t-test or Mann-Whitney U test. The effect of surgery on PBLs in patients with EC was assessed using a paired t-test or the Wilcoxon signed rank test.
Results:
The immune function of patients with EC was significantly lower than that of healthy people (P < 0.05) and those with benign uterine diseases (P < 0.05) and was related to body mass index (BMI), hypertension, diabetes, and blood lipids (P < 0.05). In patients with EC, the PBLs counts decreased significantly after surgery (P < 0.05) and more kinds of lymphocytes were affected in the laparoscopic surgery group than in the open surgery group.
Conclusions:
With the decrease of PBLs counts, the immune status of patients with EC is impaired. Metabolic syndrome (Mets), including obesity, hypertension, diabetes, and high blood lipids, also affects the immune function of patients with EC. And for EC patients, the effect of laparoscopic surgery is greater than that of open surgery. PBLs has the potential to be one of indicator during the diagnosis and treatment of EC.
Trial Registration:
This study was retrospectively registered by the Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (approval number K2023-578).
