Abstract
The objective of this study was to prospectively validate the Multinational Association of Supportive Care of Cancer (MASCC) risk-index score in an attempt to accurately predict on presentation with febrile neutropenia those cancer patients who are at low- or high-risk for development of serious medical complications during the episode. Patients who presented with febrile neutropenia during November 2000 and July 2002 were prospectively enrolled in the protocol. All patients were hospitalized until recovery or outcome of the event and were treated with broad-spectrum, empiric, intravenous antibiotic therapy. The MASCC risk-index score (based on seven independent factors present at onset of febrile neutropenia) was calculated in 64 patients with 80 febrile neutropenic episodes. Patients with a score of ≥21 were regarded as low risk; patients with a score of pp<0.001), six as a consequence of sepsis and two due to rapidly uncontrolled cancer. We correctly predicted 98.3% of low-risk patients and 86.3% of high-risk patients. This study had a positive predictive value of 98.3% and a negative predictive value of 86.4% with both a sensitivity and specificity of 95%. The MASCC risk-index score correctly identifies low- and high-risk patients at presentation with febrile neutropenia.
