Abstract

The aim of the current study was to develop and validate a nomogram based on a large population to estimate the 3‑ and 5‑year survival rates of patients with malignant melanoma (MM). Patients were selected from the Surveillance, Epidemiology and End Results database and randomly divided into the training and validation cohorts. A nomogram was developed, and was used to assess the accuracy of the model. Independent prognostic factors associated with overall survival (OS) rate were identified through multivariate analysis, and were included in the internal validation of the nomogram. The nomogram provided high C‑indexes for the training cohort [area under the time‑dependent receiver operating characteristic curve (AUC) of 0.877 for 3‑year OS rate and 0.872 for 5‑year OS rate] and the validation cohort (AUC of 0.880 for 3‑year OS rate and 0.874 for 5‑year OS rate), indicating that the model had good discrimination ability. Calibration plots showed that the predicted 3‑ and 5‑year OS rates probabilities for the training and validation groups were almost identical to the actual observations. The 3‑ and 5‑year decision curves indicated net benefits for both the training and validation cohorts. The nomogram may aid clinicians to provide more accurate prognosis prediction in patient consultations and more personalized postoperative management plans.
