Abstract:
Objective:To explore the clinical significance of serum squamous cell carcinoma antigen (SCC-Ag) in early cervical squamous cell carcinoma.
Methods:The clinicopathological data and follow-up information of 1435 patients with stage ⅠA2-ⅡA cervical squamous cell carcinoma were collected. The correlation between serum SCC-Ag level and clinicopathological feature and prognosis were analyzed. The best cut-off of serum SCC-Ag for predicting pelvic lymph node metastasis and survival of cervical squamous cell carcinoma patients were also identified.
Results:The result of univariate analysis showed that The International Federation of Gynecology and Obstetrics (FIGO) staging, tumor size, depth of cervical stromal invasion, lymphovascular space involvement, pelvic lymph node metastasis, common iliac lymph node metastasis and para-aortic lymph node metastasis were significantly related with serum SCC-Ag level (all P<0.05). The result of multivariate logistic regression analysis showed that tumor size, depth of cervical stromal invasion, pelvic lymph node metastasis and common iliac lymph node metastasis were the independent risk factors of preoperative serum SCC-Ag>2.65 ng/ml (all P<0.001). Multivariate Cox regression analysis showed that lymphovascular space involvement, SCC-Ag>3.15 ng/ml, common iliac lymph node metastasis and tumor size >4 cm were the independent prognostic risk factors (all P<0.05). The univariate analysis showed that, the tumor size, FIGO stage, depth of cervical stromal invasion and SCC-Ag level were significantly related with the recurrence of 1 096 patients without postoperative high risk factors (all P<0.05). Multivariate logistic regression analysis showed that FIGO stage (OR=1.671) and SCC-Ag>2.65 ng/ml (OR=4.490) were the independent risk factors for recurrence (both P<0.05). The best cut off of SCC-Ag for predicting early postoperative cervical lymph node metastasis of cervical squamous cell carcinoma was 2.65 ng/ml, the sensitivity was 60.8%, the specificity was 71.8%. The best cut off of SCC-Ag for predicting prognosis of cervical squamous cell carcinoma was 3.15 ng/ml, the sensitivity was 53.5%, the specificity was 71.1%.
Conclusions:Preoperative serum squamous cell carcinoma antigen is an independent prognostic risk factor of survival of patients with early cervical squamous cell carcinoma, and is significantly related with recurrence of patients without postoperative high-risk factors. It can be used as a reference factor for postoperative adjuvant radiotherapy.
