ABSTRACT
Objective:
To evaluate the association between pre-treatment neutrophil-to-lymphocyte ratio (NLR) and survival outcomes among patients with recurrent/metastatic cervical cancer treated with PD-1/PD-L1 inhibitors.Methods:
A retrospective analysis of patients with recurrent/metastatic cervical cancer treated with PD-1/PD-L1 inhibitors from 2016 to 2021 was conducted. Progression free survival (PFS) and overall survival (OS) outcomes were assessed for patients stratified by NLR (<8 vs ≥ 8) utilizing Kaplan-Meier method. Univariable analysis was performed to compare baseline characteristics between the two groups.Results:
A total of 49 patients were included in analysis. A majority of patients had squamous cell histology (57%), were PD-L1 positive (55%), received ≤ 1 prior lines of systemic therapy (57%), and had distant metastatic disease at the time of treatment (69%). The groups were well-balanced with respect to age, race, histology, smoking status, PD-L1 positivity, prior lines of treatment (≤1 vs > 1), prior radiation therapy, ECOG performance status, and disease distribution for patients with a NLR < 8 (n = 35) compared to those with a NLR ≥ 8 (n = 14). A pre-treatment NLR of < 8 was associated with improved survival (p < 0.01), with 57% (95% CI 41%, 78%) probability of survival at one year compared to 26% (95% CI 10%, 66%) for those with NLR ≥ 8. No statistically significant differences in probability of PFS at 1 year were seen between NLR < 8 compared to those with NLR ≥ 8 (p = 0.70).Conclusions:
Pre-treatment NLR may hold prognostic value for patients with metastatic/recurrent cervical cancer treated with PD-1/PD-L1 inhibitors, with NLR < 8 associated with improved survival.
