How this service works
Frank 2002 SSIGN (stage, size, grade, necrosis) for clear cell RCC after radical nephrectomy. 1997 TNM: pT1 0, pT2 1, pT3 2, pT4 0; N0/Nx 0, N1/N2 2; M0 0, M1 4; size ≥5 cm 2; nuclear grade 1–2 0, 3 1, 4 3; coagulative necrosis 2; max 15. Returns the published CSS row. Not 2002/2010 TNM. magent does not stage or read pathology. Not a diagnosis. Not a medical device.
Output
Returns the computed total SSIGN score (0–15) along with the published cancer-specific survival (CSS) row from Frank 2002, corresponding to the input parameters. Does not perform staging, pathology reading, or diagnosis.
Example use cases
Post-nephrectomy RCC prognosis estimation
“I have a patient with clear cell RCC who just had a radical nephrectomy. Pathology shows 1997 T2, N0, M0, tumor size 4.8 cm, Fuhrman grade 2, no coagulative necrosis. What is their SSIGN score?”
High-grade RCC risk stratification
“Can you compute the SSIGN score for a clear cell RCC case: 1997 T3b, N1, M0, maximum tumor size 8.5 cm, Fuhrman grade 4, coagulative necrosis present?”
Metastatic RCC prognosis lookup
“What is the Frank 2002 SSIGN score for a clear cell RCC patient staged as 1997 T2, N0, M1, tumor size 7.0 cm, Fuhrman grade 3, and no tumor necrosis?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ssignWhen to prefer
Use this endpoint when you need to compute the Frank 2002 SSIGN score specifically for clear cell RCC after radical nephrectomy using 1997 TNM staging. Prefer this over generic oncology risk tools when the caller has already assigned 1997 pathologic T, N, M stages, Fuhrman nuclear grade, tumor size in cm, and necrosis status. Not appropriate for 2002 or 2010 TNM staging, non-clear-cell subtypes, or partial nephrectomy cases.
Side effects
- Missing required query parameters (t_1997, n_1997, m_1997, tumor_size_cm, fuhrman, necrosis) returns a validation error
- Fuhrman grade outside integer range 1–4 (e.g. 0, 5, or a decimal) is rejected
- Tumor size outside clamped range 0.1–40 cm may be rejected or clamped
- Invalid enum values for T/N/M (e.g. 2002 or 2010 TNM staging like T1a/T1b) are not accepted
- Payment failure or insufficient USDC balance returns 402
