Abstract

We explored the associations between progression-free survival (PFS) after the initiation of PD-1 inhibitor therapy and the clinical parameters in patients with NSCLC. We reviewed the clinical data of patients with NSCLC treated with PD-1 inhibitor. Data of a total of 36 patients, including 16 patients with squamous cell NSCLC and 20 patients with non-squamous cell NSCLC were reviewed. Multivariate analyses identified EGFR status, C-reactive protein (CRP), and PFS following previous therapy as being significantly associated with the PFS after initiation of PD-1 inhibitor therapy in patients with NSCLC. In patients with squamous cell NSCLC, the blood neutrophil/lymphocyte ratio (NLR), serum lactate dehydrogenase (LDH), serum C-reactive protein (CRP), and PFS following previous therapy were identified as being significantly associated with the PFS after initiation of PD-1 inhibitor therapy. However, none of these associations, except for PFS following previous therapy, were found in patients with non-squamous cell NSCLC. NLR, LDH and CRP were associated with the PFS after initiation of PD-1 inhibitor therapy in patients with squamous cell NSCLC, and PFS following previous therapy was the common parameter associated with the PFS after initiation of PD-1 inhibitor therapy in both squamous-cell NSCLC and non-squamous-cell NSCLC patients.
