Here, our research’s objective was to evaluate the prognostic significance of starting point obtained NLR (dNLR), MLR, PLR, and serum levels of albumin, lactate dehydrogenase (LDH), and C-reactive protein (CRP) in early-stage NSCLC patients administrated SBRT using a bigger sample size and a database with extensive follow-up. Here, CRP is linked to non-small cell lung carcinoma.
