Predictor | RETREAT pointsb |
---|---|
AFP at LT, ng/mL | |
0–20 | 0 |
21–99 | 1 |
100–999 | 2 |
≥1000 | 3 |
Presence of microvascular invasion | 2 |
Explant largest viable tumor diameter + number of viable tumors | |
0a | 0 |
1–4.9 | 1 |
5–9.9 | 2 |
≥10 | 3 |
AFP, α-fetoprotein; HCC, hepatocellular carcinoma; LT, liver transplantation; Ref, reference.
Explant largest viable tumor diameter + number = 0 if no viable tumor is identified.
The RETREAT score is obtained by adding the total number of points scored in each of the 3 variables (range 0–8). RETREAT score = 0 if a patient has AFP 0–20 ng/mL at LT, no microvascular invasion, and no viable tumor in the explant.
