MASCC Risk Index (febrile neutropenia)
MASCC risk index (Klastersky 2000) for febrile neutropenia.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Burden of febrile-neutropenia illness
- No or mild symptoms (5)
- No hypotension
- Yes
- No chronic obstructive pulmonary disease
- Yes
- Solid tumor / no prior fungal infection
- Yes
- No dehydration requiring fluids
- Yes
- Outpatient at fever onset
- Yes
- Age < 60 years
- Yes
Result: MASCC 26: LOW risk for serious complications (>= 21) -- a candidate for outpatient/oral management per the source.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Score (max 26)
- burden of illness (no/mild 5, moderate 3) + no hypotension 5 + no COPD 4 + solid tumor/no fungal 4 + no dehydration 3 + outpatient 3 + age < 60 2.
- Risk
- >= 21 identifies a low-risk febrile-neutropenic patient -- a candidate for outpatient/oral management. Reports the index only.
What you enter
- Burden of febrile-neutropenia illness
- No hypotension (SBP > 90)
- No chronic obstructive pulmonary disease
- Solid tumor / no prior fungal infection
- No dehydration requiring fluids
- Outpatient at fever onset
- Age < 60 years
