To explore the putative association of the Merkel cell polyomavirus (MCPyV) to the etiology of Non-small-cell lung-cancer.


A retrospective molecular case–control study was conducted in Non-small-cell lung-cancer patients and their relatives. During the screening program, 106 patient samples (including 77 serum biopsies and 29 parafin embedded tissues) and 90 non-cancer counterparts (50 serum biopsies and 40 parafin embedded tissues) were recruited for being analyzed by realtime-PCR and sequencing.


Our study is the first to demonstrate the presence of Merkel cell polyomavirus DNA in Vietnamese lung cancer with a prevalence of 20.6% cases and less than 1% of controls. This difference was statistically significant and consistent with previous studies.


This difference was statistically significant and consistent with previous studies, hence support a hypothesis that MCPyV is partly associated with the pathogenesis of NSCLC in a subset of Vietnamese patients.
