x402
NCCN-IPI Calculator for DLBCL (Zhou 2014) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes the NCCN-IPI prognostic score for diffuse large B-cell lymphoma (DLBCL) using the Zhou 2014 refinement, returning a total score (0–8) and risk group classification.

How this service works
Zhou 2014 NCCN-IPI for DLBCL in the rituximab era: age (≤40 0, 41–60 1, 61–75 2, ≥76 3), LDH/ULN (≤1 0, >1–3 1, >3 2), Ann Arbor III or IV 1, major-organ extranodal (bone marrow, CNS, liver/GI tract, or lung) 1, ECOG ≥2 1; max 8. Low 0–1, low_intermediate 2–3, high_intermediate 4–5, high 6–8. Deterministic published score; not a DLBCL diagnosis or treatment choice; not Shipp IPI, not R-IPI, not CNS-IPI. magent does not assay LDH or stage lymphoma.
Output
Returns the computed NCCN-IPI total score (integer 0–8) and the corresponding risk group classification: low (0–1), low_intermediate (2–3), high_intermediate (4–5), or high (6–8), based on the Zhou 2014 rituximab-era refinement of the International Prognostic Index for DLBCL.
Example use cases
Oncology chart review risk stratification
“I'm reviewing a DLBCL patient who is 72 years old, has an LDH/ULN ratio of 1.8, ECOG status of 2, is stage III, and has no major-organ extranodal sites — can you calculate their NCCN-IPI score and tell me which risk group they fall into?”
Clinical trial eligibility screening
“We need the NCCN-IPI risk group for a 55-year-old DLBCL patient: LDH/ULN ratio 3.5, ECOG 0, Ann Arbor stage II, no major-organ extranodal involvement — run the Zhou 2014 NCCN-IPI calculation.”
Tumor board case presentation prep
“For our tumor board, can you compute the NCCN-IPI score for a 43-year-old patient with DLBCL, LDH/ULN ratio of 0.9, ECOG 1, Ann Arbor stage IV, and lung involvement as an extranodal major organ site?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/nccn_ipiWhen to prefer
Use this endpoint when you need a deterministic, published NCCN-IPI score (Zhou 2014 refinement) for a DLBCL patient in the rituximab era — particularly when you want the refined four-tier age scoring rather than the binary >60 cutoff in the original Shipp IPI. Prefer this over sibling endpoints (Shipp 1993 IPI, R-IPI, CNS-IPI) when the clinical question specifically concerns NCCN-IPI risk stratification as defined by Zhou 2014. This endpoint is pure computation — the caller must supply all pre-assessed clinical values (ECOG, stage, LDH/ULN, extranodal status); it does not interpret labs or imaging.
Side effects
- Missing required query parameters (age, ecog, ldh_uln_ratio, stage_iii_or_iv, extranodal_major) returns a validation error
- Age outside 18–120 range or LDH/ULN outside 0.1–20 range may trigger schema validation failure
- ECOG value outside 0–4 may be rejected
- Payment failure or insufficient USDC balance returns a 402 error
- Network timeout if the API is temporarily unavailable
