A high level of circulating tumor DNA (ctDNA) has been linked to poor survival in patients with certain solid tumors. In spite of this, it is still unclear whether ctDNA is associated with poor survival in small cell lung cancer (SCLC). To investigate the above association, we conducted a systematic review and meta-analysis. WebEleven studies (sample size from 15 to 120) with 562 patients, basically located in East Asia, were published between 2002 and 2016. 23–33 All the included publications provided data on the correlation between circulating EBV DNA and prognosis in patients with ENKTL.
