NPPB and urogenital neoplasm: Patients with urogenital neoplasms had the highest incidence of NT-proBNP levels above 600 ng/L, with 12 individuals (30.0%), although this was not significantly higher than patients with other localizations, such as the digestive system (13 patients, 32.5%, p=0.3771), lung (10 patients, 25.0%, p=0.3771), breast (2 patients, 5.0%, p=0.3771), or other locations (3 patients, 7.5%, p=0.3771).
