This study developed a multivariable disease-specific prognostic model for Merkel cell carcinoma incorporating clinical, pathologic, and demographic variables. The model provides individualized prognostic estimates that can guide treatment intensity and surveillance planning for MCC patients.

Take-Home Messages

  • A validated prognostic model for MCC can help individualize treatment intensity and surveillance based on patient-specific risk factors.
  • Integration of multiple clinical and pathologic variables improves prognostic accuracy beyond single-factor staging in MCC.

Abstract

Merkel cell carcinoma (MCC) is a highly aggressive cutaneous malignancy for which accurate prognostication is necessary to support clinical management. (1) To determine which survival endpoint-disease-specific death (DSD) or overall survival (OS)-was better stratified by MCC American Joint Cancer Committee eighth edition staging. (2) To develop a multivariable model for enhanced MCC survival predictions. A retrospective analysis of 10,958 histologically confirmed MCC patients between January ...
