How this service works
Psallidas 2018 Table 2A clinical PROMISE for malignant pleural effusion: chemo 0/4, radiotherapy 0/2, haemoglobin g/dL 0-4, WBC 10^9/L 0/2/4/7/10, CRP mg/L 0/3/5/8/11, ECOG 0-1=0 or 2-4=7, cancer mesothelioma 0 / other 4 / lung 5. Groups A 0-20 <25%, B 21-27, C 28-35, D >35 >=75% 3-month mortality. Not TIMP1. Not a treatment order.
Output
Returns the computed PROMISE integer score (0–44 range based on weighted clinical inputs) and the corresponding risk group: Group A (0–20, <25% 3-month mortality), Group B (21–27), Group C (28–35), or Group D (>35, ≥75% 3-month mortality).
Example use cases
Oncology consult 3-month prognosis
“I have a patient with malignant pleural effusion from mesothelioma — no prior chemo, no radiotherapy, haemoglobin 12 g/dL, WBC 5.5 ×10⁹/L, CRP 7 mg/L, ECOG 0. Calculate their PROMISE score and tell me which risk group they fall into.”
High-risk MPE triage decision
“My patient has an ECOG of 3, WBC of 18 ×10⁹/L, CRP of 120 mg/L, haemoglobin of 8 g/dL, lung cancer with pleural effusion, previous chemotherapy but no radiotherapy — what does the PROMISE score come out to, and is this a high 3-month mortality risk?”
Documenting prognosis for MDT meeting
“For our multidisciplinary team meeting, I need the Psallidas PROMISE score for a patient: other cancer type, prior radiotherapy yes, no prior chemo, haemoglobin 9.5 g/dL, WBC 11 ×10⁹/L, CRP 28 mg/L, ECOG 2. What group and approximate 3-month mortality risk?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/promiseWhen to prefer
Use this endpoint when you need to compute the validated Psallidas 2018 PROMISE prognostic score specifically for malignant pleural effusion (MPE) patients. It is the correct tool for 3-month mortality risk stratification in MPE using the seven-variable Table 2A model. Do not use this for general cancer prognosis, TIMP-1-based scoring, or non-pleural effusion contexts.
Side effects
- Missing required query parameters (chemotherapy, radiotherapy, haemoglobin_g_dl, wbc, crp_mg_l, ecog, cancer_type) returns a 400 error
- Out-of-range numeric inputs (e.g. WBC outside 0.1–80, CRP outside 0–500) may return validation error
- Invalid enum value for cancer_type (must be mesothelioma, lung, or other) returns error
- ECOG grade 5 (dead) is not scored and should not be submitted
- Payment failure (x402) returns 402 if USDC payment header is missing or invalid
