# CISNE Febrile Neutropenia Risk Score Calculator

> CISNE Febrile Neutropenia Risk Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Carmona-Bayonas 2015 CISNE score for stable adult solid-tumor febrile neutropenia patients, returning a numeric score and risk category (low/intermediate/high).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cisne-febrile-neutropenia-risk-score-calculator-0ce99274
```

Example prompt: My patient is a solid-tumor adult with febrile neutropenia who looks clinically stable. They have ECOG ≥2, stress hyperglycemia, no COPD, no chronic cardiovascular disease, no mucositis grade ≥2, and monocytes are not below 200 — can you calculate their CISNE score and tell me what risk category they fall into?

## When to prefer this

Use this endpoint when you need a deterministic, citation-backed CISNE risk score for a seemingly stable adult solid-tumor febrile neutropenia patient and all six clinical flags have already been assessed by a clinician. Prefer CISNE over MASCC when the validated population (solid tumor, clinically stable) matches. Do not use for pediatric patients, hematologic malignancies, or unstable presentations.

## Known failure modes

- Missing required boolean parameter returns a validation error
- Passing numeric or non-boolean values for flag fields causes schema rejection
- Applying the score to pediatric patients, hematologic malignancies, or unstable patients is a clinical misuse outside the instrument's validated population
- Score does not incorporate clinical judgment — caller must independently verify each input flag before submission

## How this service works

Carmona-Bayonas 2015 CISNE: ECOG ≥2 (2), stress hyperglycemia (2), COPD (1), chronic cardiovascular disease (1), NCI CTC mucositis ≥2 (1), monocytes <200/µL (1). Max 8. Low 0, intermediate 1–2, high ≥3. Seemingly stable adult solid-tumor febrile neutropenia only. Deterministic published score with citation; not MASCC; not an outpatient-chemotherapy or discharge order. magent does not assign ECOG, assay glucose, diagnose COPD, read an echocardiogram, grade mucositis, or count monocytes.

## Output

Returns the numeric CISNE total score (0–8) and the associated risk category: low (0), intermediate (1–2), or high (≥3), based on the six caller-supplied boolean clinical flags weighted per the Carmona-Bayonas 2015 publication.
