The role of an immune checkpoint score in resected non-small cell lung cancer patients’ prognosis

Lung cancer is the leading cause of cancer related death in both sex and its incidence is still increasing. Non-small cell lung cancer (NSCLC) accounts for approximately 85% of all lung cancers (1). Despite many treatment options are available, most of NSCLC patients’ diagnoses are reached in advanced stages and their prognosis remains poor. Over the past few years, a variety of prognostic and predictive factors have been investigated in patients with NSCLC, and several prognostic models have been proposed to predict the outcome of patients with NSCLC (2).
