How this service works
Motzer 1999 MSKCC: KPS <80, LDH >1.5×ULN, hemoglobin <LLN, corrected calcium >10 mg/dL, no prior nephrectomy; 1 point each, max 5. Favorable 0, intermediate 1–2, poor ≥3. Deterministic published score with citation; not an RCC diagnosis or treatment recommendation; not IMDC; not Motzer 2002/2004. magent does not assign KPS or assay LDH, hemoglobin, or calcium.
Output
Returns the total Motzer 1999 MSKCC score (0–5, one point per positive risk factor) and the corresponding risk group: favorable (0 points), intermediate (1–2 points), or poor (≥3 points), along with a citation to the original Motzer 1999 publication. Does not return a diagnosis, treatment recommendation, or IMDC classification.
Example use cases
Stratifying newly diagnosed metastatic RCC
“My patient has newly diagnosed metastatic kidney cancer. Their KPS is less than 80, LDH is elevated above 1.5 times ULN, hemoglobin is below normal, corrected calcium is 11 mg/dL, and they haven't had a nephrectomy — what's their Motzer 1999 MSKCC risk group?”
Favorable-risk RCC confirmation
“I have an RCC patient with normal KPS, normal LDH, normal hemoglobin, corrected calcium of 9 mg/dL, and they had a prior nephrectomy — can you run the Motzer 1999 score and tell me if they fall in the favorable risk category?”
Embedding Motzer score in oncology workflow
“For our clinical trial eligibility pipeline, calculate the 1999 Motzer MSKCC score for a patient flagged as: KPS ≥80, LDH normal, hemoglobin normal, corrected calcium normal, prior nephrectomy done — give me the numeric score and risk group.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/motzerWhen to prefer
Use this endpoint when you need the original cytokine-era Motzer 1999 MSKCC five-factor prognostic model specifically (KPS, LDH, hemoglobin, corrected calcium, nephrectomy status). Prefer this over the IMDC/Heng 2009 endpoint when the clinical context calls for the historical Motzer 1999 criteria — e.g., cytokine-era trial comparisons or when the ordering clinician specifies the 1999 MSKCC model. Do not use this for IMDC risk stratification used in contemporary immunotherapy trials.
Side effects
- Missing any of the five required boolean parameters returns a validation error
- Passing non-boolean values for the risk factor fields causes a schema rejection
- Confusing this with the IMDC (Heng 2009) model may yield incorrect risk stratification for immunotherapy-era patients
- Confusing with Motzer 2002 or 2004 variants may cause misclassification if criteria differ
