MASCC Score for Febrile Neutropenia

For febrile neutropenia: a score of 21 or more means a low risk of serious complications.

Scoring

Seven variables with a maximum score of 26; 21 or more means low risk. In the original study its positive predictive value for no serious complication was 91% [1]. “Burden of illness” is a clinical judgement: none or mild 5, moderate 3, severe 0 [1].

Outpatient treatment: conditions

The ASCO/IDSA guideline suggests outpatient treatment for low-risk patients who [2]:

  • are clinically stable without a focal infection, pneumonia, catheter infection or need for intravenous therapy;
  • can take oral drugs, have a caregiver and can reach the hospital within about one hour;
  • are observed for some hours and receive the first antibiotic dose there.

Usual regimen: a fluoroquinolone (ciprofloxacin or levofloxacin) plus amoxicillin-clavulanate; clindamycin instead in penicillin allergy [2]. If the patient was on fluoroquinolone prophylaxis, oral outpatient treatment is not appropriate [2].

Limitation

MASCC is less valid in haematological malignancies with prolonged neutropenia (e.g., acute leukaemia induction or allogeneic transplant); these patients are usually admitted [3].
