Sentinel lymph node positivity and overall survival in immunosuppressed patients with Merkel cell carcinoma: A national cohort study

Merkel cell carcinoma (MCC), a neuroendocrine cutaneous malignancy, may be especially aggressive in immunocompromised patients.(1,2) Factors associated with sentinel lymph node (SLN) involvement and overall survival (OS) have been described for the general population with clinically-localized MCC, but prognostic factors in immunosuppressed patients have not been well characterized.(3,4) The study objectives were to identify characteristics associated with SLN status and OS in this patient population.
