Background:
Eribulin is widely used for the treatment of breast cancer and soft-tissue sarcoma (STS). Previous studies identified the pre-treatment absolute lymphocyte count, baseline neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein concentration as potential prognostic markers in patients with breast cancer treated with eribulin. However, prognostic factors for eribulin treatment in patients with STS have not been identified.
Patients And Methods:
This was a retrospective analysis of data collected prospectively from 53 patients who were treated with eribulin for recurrent or metastatic STS between March 2016 and August 2019. Univariate and multivariate analyses were performed to determine the predictive factors of durable clinical benefit, progression-free survival, and overall survival.
Results:
L-Sarcoma histology [hazard ratio (HR)=28.20, 95% confidence intervaI (CI)=1.67-476.00; p=0.021] and pre-treatment NLR <3.0 (HR=9.96, 95% CI=1.28-77.7; p=0.028) were independent factors predictive of durable clinical benefit. In addition, pre-treatment NLR <3.0 (HR=0.34, 95% CI=0.16-0.74; p=0.0059) and male sex (HR=0.23, 95% CI=0.10-0.52; p<0.001) were independent factors predictive of better progression-free survival.
Conclusion:
This retrospective study found that baseline NLR predicts the efficacy of eribulin for STS.
