Management of a patient with acute lymphoblastic leukaemia presenting with febrile neutropenia:

  • Immediate referral and assessment: Suspect neutropenic sepsis in patients undergoing anticancer treatment who become unwell and refer immediately for assessment in secondary or tertiary care as this is a medical emergency .
  • Initial clinical assessment: Conduct a thorough history and examination, and perform investigations including full blood count, kidney and liver function tests, C-reactive protein, lactate, and blood cultures .
  • Empiric antibiotic therapy: Start empiric intravenous antibiotic therapy immediately, preferably beta-lactam monotherapy with piperacillin with tazobactam unless contraindicated . Avoid aminoglycosides or glycopeptides initially unless specific indications exist .
  • Risk assessment: Assess the patient’s risk of septic complications within 24 hours using a validated risk scoring system by a healthcare professional competent in managing anticancer treatment complications .
  • Ongoing management: For high-risk patients, daily clinical review and reassessment of septic risk is required; do not switch empiric antibiotics unless clinical deterioration or microbiological indication occurs .
  • Antibiotic duration and discharge: Continue inpatient empiric antibiotics if fever persists without alternative cause; discontinue antibiotics once neutropenic sepsis responds irrespective of neutrophil count. Switch to oral antibiotics and consider discharge only after reassessment confirms low risk and social circumstances are appropriate .
  • Supportive care and facilities: Patients with acute lymphoblastic leukaemia at risk of prolonged neutropenia should be managed in facilities with appropriate isolation, rapid access to blood products, and emergency imaging .
  • Prevention: Consider prophylactic fluoroquinolone (ciprofloxacin) during expected neutropenia periods in adults, monitoring for resistance and side effects .
