Abstract:
Objective:To explore the prognostic factors of patients with cervical cancer and establish a nomogram to predict overall survival of patients with cervical cancer.
Methods:The information of age, pathological features, radiotherapy and chemotherapy of 513 patients with cervical cancer were collected. The Log-rank test and Cox regression models were used for analyzing overall survival of patients with cervical cancer. A nomogram was established based on the results of multivariate analysis. The C-index, calibration plots and receiver operating characteristic curves were used to evaluate the predictive ability and accuracy of the nomogram.
Results:A total of 456 patients were followed up in this study, 57 cases were lost to follow-up, the loss rate was 11.11%. As the results of univariate and multivariate analysis showed that the adenocarcinoma, poor differentiation, tumor size ≥4 cm, advanced stage, and no radiotherapy were independent risk factors for overall survival of cervical cancer. A nomogram for overall survival of cervical cancer was established based on multivariate analysis, and after validated, the C-index of the nomogram was 0.83. Meanwhile, the 1-, 3-, 5-year calibration plots of the nomogram matched the 45-degree line well. In addition, the 1-, 3-, 5-year AUC values of the nomogram were 0.836, 0.847 and 0.824, respectively.
Conclusion:Based on the results of multivariate analysis, the five prognostic factors of cervical cancer, including histological type, cell differentiation, tumor size, stage, and radiotherapy were used to establish a nomogram with good predictive ability and accuracy. The establishment of the overall survival nomogram of cervical cancer was useful for gynecological oncologists to make a more accurate assessment of the prognosis of patients with cervical cancer and guide the clinical individualized treatment.
