External validation of the MSKCC nomogram to estimate five-year overall survival after sur

39,805 patient records from the Netherlands Cancer Registry were used to externally validate the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram for predicting five-year overall survival after colon cancer surgery. The data covers patients diagnosed between 2010 and 2016, with a median follow-up of 5.6 years. The validation study was conducted by researchers including Marinde J. G. Bond from Utrecht University.

Use Cases

• Validate a clinical prediction model based on patient age, sex, and tumor characteristics mentioned in the description.
• Assess model calibration and discrimination for survival probability estimates in a European population.
• Study the potential improvement of a prognostic model by adding factors like primary tumour location.
• Support clinical decision-making by providing personalized survival estimates to inform patients.

Strengths

• Includes 39,805 patient records, providing a substantial sample for validation.
• Reports specific performance metrics: a C-index of 0.75 and a Brier score of 0.10.
• Data is population-based, sourced from a national cancer registry (Netherlands Cancer Registry).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific Dutch cohort from 2010-2016.
