Highlights • Multi-centre UK study of 425 patients undergoing curative intent radiotherapy for NSCLC. • Higher pre-NLR, post-NLR and change in NLR plus lower post-ALC were all independent predictors of worse survival. • Pre-NLR > 2.5, post-NLR > 5.5, change in NLR > 3.6 and post-ALC < 0.8 optimally predicted poor survival. • Median OS high vs low-risk group: pre-NLR 770 vs 1009, post-NLR 596 vs 1287, change in NLR 553 vs 1214 and post-ALC 594 vs 1287 days.

Highlights • Two validated risk prediction models for disease recurrence and death are presented. • The performance of the scores are modest. • Rates of further curative intent treatment for disease recurrence were low (4%). • The majority with disease recurrence were managed with best supportive care (57%). • More advanced risk prediction tools and research into optimal follow-up is needed.

Background Few studies are available concerning prevalences of abnormalities in the Thoroughbred horse population. Objectives Determine the prevalence of commonly observed abnormalities in a National Hunt Thoroughbred population using results of pre‐purchase examinations conducted at Thoroughbred sales venues. Study design Retrospective cross‐sectional study.
