Adjuvant chemotherapy refers to additional treatment, usually given after surgery where all detectable disease has been removed, but where there remains a statistical risk of relapse due to occult disease.

North American and Australian tumor samples were evaluated for presence of MCPyV and a higher incidence in North American samples were positive for MCPyV when compared to Australia, suggesting a possible strain variant.
- Feng H, Shuda M, Chang Y, Moore P. Clonal Integration of a Polyomavirus in Human Merkel Cell Carcinoma. Science 2008; 319:1096-1100.
A technique called digital transcriptome subtraction (DTS) was used to identify a new virus, which is a previously unknown polyomavirus that we call Merkel cell polyomavirus (MCV or MCPyV). MCPyV sequences were detected in 8 of 10 (80%) MCC tumors (lower incidence in non-MCC tumors).

Merkel cell polyomavirus (MCPyV) has been detected in approximately 75% of patients with the rare skin cancer Merkel cell carcinoma. We investigated the prevalence of antibodies against MCPyV in the general population and the association between these antibodies and Merkel cell carcinoma.
