CTSV and neoplasm: In contrast, analysis of Her2-enriched (N = 251) (HR = 0.5256, log-rank p = 0.0010) and basal tumours (N = 618) (HR = 0.7392, log-rank p = 0.00238) revealed that elevated CTSV expression was associated with a more favourable outcome, in agreement with that observed when ER-negative patients were analysed collectively (Fig. 1f, g).
