BACKGROUND Cervical cancer is a gynecological malignancy common in middle-aged and older patients,with a high mortality rate.Spondin-2 is an extracellular matrix protein that involved in innate and acquired immune responses.Herein,we investigated the relationship between serum Spondin-2 expression,tumor invasion and infiltration,and immune response in patients with cervical cancer and provided a theoretical basis for clinical practice.AIM To investigate the relationship between serum Spondin-2 expression and cervical cancer-related indicators.METHODS Overall,147 patients with cervical cancer who were admitted to our institution between January 2019 and August 2019 were assigned to the cervical cancer group,and 92 patients with benign uterine lesions and 86 healthy individuals were assigned to the benign and control groups,respectively.In each group,serum Spondin-2 expression was measured,and the receiver operating characteristic(ROC)curve was determined.Patients with cervical cancer were classified into high or low Spondin-2 groups depending on the Spondin-2 threshold value used for diagnosing cervical cancer.Patient’s clinical data were collected to compare the clinicopathologic characteristics,immune cytokine levels,and prognosis of patients with varying Spondin-2 expression levels.RESULTS The expression level of serum Spondin-2 was significantly higher in the cervical cancer group than in the benign and control groups(P<0.05).According to the ROC curve,the cutoff value of Spondin-2 used in the diagnosis of cervical carcinoma was 25.68±7.11μg/L.The proportion of patients with Federation of Gynecology and Obstetrics stage III,nerve invasion,vascular invasion,and lymph node metastasis was higher in the high Spondin-2 group than in the low Spondin-2 group(P<0.05).Interleukin-5(IL-5)and IL-4 Levels were higher in the high Spondin-2 group than in the low Spondin-2 group.In contrast,IL-2 and tumor necrosis factor-αlevels were lower in the high Spondin-2 group than in the low Spondin-2 group(P<0.05).After 3 years
