Prognostic Value of Serum Procalcitonin Levels in Patients With Febrile Neutropenia Presenting to the Emergency Department.

Background: Various risk-stratification scores have been developed to identify low-risk febrile neutropenia (FN). The Multinational Association of Supportive Care in Cancer (MASCC) score is a commonly used validated scoring system, although its performance varies due to its subjectivity. Biomarkers like procalcitonin (PCT) are being used in patients with FN to detect bacteremia and additional complications.
