High pretreatment neutrophil–lymphocyte ratio predicts recurrence and poor prognosis for combined small cell lung cancer

摘要

Backgrounds Compared to pure small cell lung cancer (SCLC), combined small cell lung cancer (C-SCLC) has its own characteristics. High neutrophil to lymphocyte ratio (NLR) and platelet–lymphocyte ratio (PLR) have been shown to be related to poor prognosis in several types of tumors. The aim of this study was to explore the prognosis value of NLR and PLR in patients with C-SCLC.
