NPPB and neoplasm: Increasing NT-proBNP concentrations were associated with greater 5-year mortality risk in unadjusted analyses (HR = 1.985; 95%CI [1.400–2.814], p < 0.001) and after controlling for patient age, gender, history of cardiovascular disease, histological tumor diagnosis and adjuvant therapies (HR = 1.845; 95%CI [1.166–2.920], p = 0.009).
