Real‐world prevalence of PD‐L1 positivity in early‐stage/metastatic triple‐negative breast cancer: primary results and pathology insights from the global retrospective observational VANESSA study

open access: yesHistopathology, EarlyView.
In the real‐world VANESSA study in triple‐negative breast cancer, PD‐L1‐positive prevalence was 38% in early‐stage and 20% in metastatic tumours, lower than in prospective trials. The lower prevalence in smaller versus larger tissue samples and by local versus central assessment underlines the importance of robust PD‐L1 testing to determine eligibility

Combining δ2H and δ34S stable isotopes identifies diverse moult strategies in a short‐distance migratory bird

open access: yesIbis, EarlyView.
Moult strategies in birds can vary considerably even within a single species, particularly in terms of where moulting takes place. Yet, the factors underlying this variation and its consistency across years and individuals remain poorly understood. One such strategy, moult migration, involves individuals moving to a specific moulting location amid ...
