How this service works
Yang 2011 REACH-B 17-point HCC risk (non-cirrhotic REVEAL-HBV). Sex female 0, male 2; age 30-65 (30-34 0 through 60-65 6); ALT U/L <15 0, 15-44 1, >=45 2; HBeAg positive 2; HBV DNA copies/mL <10000 0, 10000-99999 3, 100000-999999 5, >=1000000 4. Returns score 0-17 and published 3/5/10-year percents. Not a diagnosis, not a biopsy, not for cirrhosis. magent does not assay ALT or HBV DNA.
Output
Returns the computed REACH-B integer score (0–17) derived from the five weighted Yang 2011 inputs, along with the published 3-year, 5-year, and 10-year HCC incidence percentages corresponding to that score. Does not provide a diagnosis and is not applicable to patients with cirrhosis.
Example use cases
Hepatology clinic HCC risk stratification
“I have a 55-year-old female chronic HBV patient, no cirrhosis, ALT is 30 U/L, HBeAg negative, HBV DNA 85,000 copies/mL — can you compute her REACH-B score and tell me her 5- and 10-year HCC risk?”
Research cohort HCC risk scoring
“For a research dataset entry: male, age 62, ALT 18 U/L, HBeAg negative, HBV DNA 500 copies/mL — what is his Yang 2011 REACH-B score and the published 3-year HCC probability?”
Patient counseling HCC risk estimate
“My hepatitis B patient is a 38-year-old male, ALT 60 U/L, HBeAg positive, HBV DNA 1,200,000 copies/mL, no cirrhosis — run the REACH-B calculator so I can discuss his 10-year liver cancer risk with him.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/reach_bWhen to prefer
Use this endpoint when you need to compute the validated Yang 2011 REACH-B score specifically for non-cirrhotic chronic hepatitis B patients aged 30–65 and want the published 3/5/10-year HCC risk percentages. Prefer this over generic risk tools when the patient profile matches the REVEAL-HBV derivation cohort and you have caller-supplied ALT and HBV DNA in copies/mL (not IU/mL). Do not use for cirrhotic patients, patients outside the 30–65 age range, or when you need a biopsy-based fibrosis assessment.
Side effects
- Age outside 30–65 is rejected — the model does not score ages below 30 or above 65
- Invalid or out-of-range ALT (must be 1–10,000 U/L) returns an error
- HBV DNA outside 0–10,000,000,000 copies/mL returns an error
- Invalid sex enum value (not 'male' or 'female') returns a validation error
- Missing required query parameters return a 400-level error
- Payment failure (x402) if USDC funds are insufficient
