How this service works
Swensen 1997 Mayo Clinic logistic probability of malignancy for a 4-30 mm radiologically indeterminate solitary pulmonary nodule. Inputs: age, current or former smoking, extrathoracic cancer diagnosed ≥5 years before the nodule, largest diameter in mm, caller-assigned spiculation, and caller-assigned upper-lobe location. Returns logit x and P = e^x / (1 + e^x). magent does not read the film. Not Gould 2007, not Brock, not a diagnosis, not a biopsy order, and not a medical device.
Output
Returns the logit linear predictor (x) and the derived malignancy probability P = e^x / (1 + e^x), both as numeric values, based on the Swensen 1997 Mayo Clinic logistic regression model for indeterminate solitary pulmonary nodules.
Example use cases
Pulmonary nodule triage in primary care
“My patient is a 72-year-old former smoker with a 22mm upper-lobe nodule that looks spiculated on CT — no history of extrathoracic cancer. Can you run the Swensen Mayo model and tell me the malignancy probability?”
Radiology report augmentation workflow
“For a 55-year-old never-smoker with a 10mm non-spiculated lower-lobe nodule and a colon cancer diagnosed 7 years ago, what does the Swensen 1997 calculator give for malignancy probability?”
Comparing risk before pulmonology referral
“I have two patients with incidental nodules. First: 61-year-old current smoker, 18mm upper-lobe nodule, spiculated, no prior cancer. Second: 48-year-old never-smoker, 8mm lower-lobe nodule, not spiculated, no cancer history. Can you compute the Mayo SPN malignancy probability for both?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/mayo_spnWhen to prefer
Use this endpoint when you need a validated, reference-model logistic probability for an adult patient with a 4–30 mm radiologically indeterminate solitary pulmonary nodule and you have the six Swensen 1997 input variables available. Prefer this over manual calculation to avoid arithmetic errors and to get a machine-readable logit + probability pair. Do not use for nodules outside the 4–30 mm derivation range, pediatric patients, nodules with a definitive radiological diagnosis, or when the Gould 2007 or Brock models are required by your clinical protocol.
Side effects
- Missing required query parameters (age, smoke, cancer, diameter_mm, spiculation, upper_lobe) → 400 Bad Request
- Age outside 18–120 range or diameter outside 4–30 mm range → validation error or clamped result
- Payment not provided or insufficient USDC → 402 Payment Required
- Non-boolean value passed for boolean fields → schema validation error
- Network timeout or server unavailability → 5xx error
