Summary

This 2020 Nature Medicine study, as suggested by its title, investigated IL-8 as a potential predictive biomarker for immunotherapy efficacy. The authors appear to have found that both systemic and tumour-microenvironment IL-8 levels associate inversely with clinical benefit from PD-L1 checkpoint inhibitor therapy, potentially identifying a mechanistic basis for treatment resistance in a subset of cancer patients.

UK applicability

Findings would be directly applicable to UK oncology practice and NHS immunotherapy provision, informing patient stratification and treatment selection strategies. However, UK applicability depends on whether the study population and tumour types reflect UK patient demographics and disease burden.

Key measures

Systemic IL-8 concentration, tumour-associated IL-8 expression, clinical benefit from PD-L1 blockade (response rates, progression-free survival)

Outcomes reported

The study examined associations between systemic and tumour-associated interleukin-8 (IL-8) levels and clinical benefit from PD-L1 checkpoint inhibitor blockade in cancer patients. As suggested by the title, elevated IL-8 correlated with reduced response to immunotherapy.
