Follow-up and statistical analysis
After hospital discharge, all patients were subjected to regular
follow-up examinations based on NCCN guidelines. Follow-up evaluation
comprised gynecological examination, cervical screening, computed
tomography scans of the chest and abdomen, and examination of tumor
markers. Distant metastasis data were recorded during follow-up. The
endpoint of the follow-up examination was the death of the patient, and
the alive patients were followed-up until July 28, 2022.
Enumeration data were expressed in case number and rates (%) and were
treated with χ 2 Test. Kaplan Meier method was used to draw the survival
curve, and the Cox Regression method was used for simple and
multivariate factor analysis. P<0.05 indicated statistically
significant differences. All statistical analyses were performed with
SPSS 23.0 software.
