Abstract

Merkel cell carcinoma (MCC) is a rare skin tumour of neuroendocrine origin with aggressive behaviour. The aims of this study were to investigate the association of p63 + MCC with clinicopathological features and to estimate survival through a systematic review and meta-analysis. A comprehensive search of PubMed, Embase, Scopus and Virtual Health Library following the PRISMA guidelines was conducted on September 2017. DerSimonian and Lard random-effects models were used to calculate survival-weighted means and their corresponding 95% confidence intervals (CI) among studies. Five studies met our inclusion criteria after screening 77 citations and 36 full-text articles. The included studies enrolled 413 patients with MCC. We observed that p63 + MCC was significantly associated with mortality with OR 2.92 (95% CI [1.66–5.13]). The summary hazard ratio of multivariate analysis was 1.99 (95% CI [1.32–3.01]). The only clinicopathological feature associated with p63 + MCC with statistical significance was the Merkel cell polyomavirus (MCPyV) status. The presence of MCPyV was associated as a protective factor for the expression of p63 (OR 0.25, 95% CI [0.08–0.73]). These results support that p63 + MCC evaluated by immunohistochemistry has a poor outcome. Therefore, we suggest p63 to be performed when staging MCC.
