Background: Neutropenic sepsis is a life-threatening oncologic emergency and a major cause of morbidity and mortality among cancer patients receiving cytotoxic chemotherapy, hematopoietic stem cell transplantation, or intensive immunosuppressive therapy. Profound neutropenia impairs host defense mechanisms, resulting in rapid progression from localized infection to severe sepsis and septic shock. Timely recognition and prompt initiation of evidence-based management are crucial for improving outcomes.

Objective: To review the epidemiology, risk factors, diagnostic challenges, and contemporary management strategies for neutropenic sepsis in critically ill cancer patients.

Methods: A narrative review of current literature, international guidelines, and recent advances in the management of neutropenic sepsis was conducted. Emphasis was placed on early diagnosis, antimicrobial stewardship, hemodynamic support, organ support strategies, and multidisciplinary critical care approaches.

Results: Febrile neutropenia remains the most common clinical presentation, with bacterial pathogens predominating in the early phase, although fungal and viral infections contribute significantly in prolonged neutropenia. Risk stratification using validated scoring systems facilitates appropriate triage and treatment decisions. Early administration of broad-spectrum empirical antibiotics within the first hour of recognition remains the cornerstone of therapy. Hemodynamic optimization, source control, timely escalation of antimicrobial therapy, and organ support interventions are critical in patients developing septic shock or multi – organ dysfunction. Emerging diagnostic modalities, including rapid molecular diagnostics and biomarkers, may enhance pathogen identification and antimicrobial targeting. Despite advances in supportive care, mortality remains substantial in patients requiring intensive care admission.

Conclusion: Neutropenic sepsis continues to represent a critical challenge in oncologic and intensive care practice. Early recognition, prompt empirical antimicrobial therapy, aggressive resuscitation, and coordinated multidisciplinary management are essential to improve survival. Ongoing advances in diagnostics, antimicrobial strategies, and critical care delivery offer opportunities to further optimize outcomes in this vulnerable patient population.
