Abstract
Aim
This study aimed to investigate the utility of C-reactive protein (CRP) and alpha-fetoprotein (AFP) in immunotherapy (CRAFITY) score in hepatocellular carcinoma (HCC) patients receiving atezolizumab and bevacizumab (Atez/Bev).
Methods
This retrospective cohort study included a total of 297 patients receiving Atez/Bev from September 2020 to November 2021 at 21 different institutions and hospital groups in Japan. Patients with AFP ≥ 100 ng/mL and those with CRP ≥ 1 mg/dL were assigned a CRAFITY score of 1 point.
Results
The patients were assigned CRAFITY scores of 0 points (n = 147 [49.5%]), 1 point (n = 111 [37.4%]), and 2 points (n = 39 [13.1%]). AFP ≥ 100 ng/mL and CRP ≥ 1.0 mg/dL were significantly associated with progression-free survival (PFS) and overall survival (OS). The median PFS in the CRAFITY score 0, 1, and 2 groups was 11.8 months (95% confidence interval [CI] 6.4-not applicable [NA]), 6.5 months (95% CI 4.6–8.0), and 3.2 months (95% CI 1.9–5.0), respectively (p < 0.001). The median OS in patients with CRAFITY score 0, 1 and 2 was not reached, 14.3 months (95% CI 10.5-NA), and 11.6 months (95% CI 4.9-NA), respectively. The percentage of patients with grade ≥ 3 liver injury, any grade of decreased appetite, any grade of proteinuria, any grade of fever, and any grade of fatigue was lowest in patients with a CRAFITY score of 0, followed by patients with CRAFITY scores of 1 and 2.
Conclusions
The CRAFITY score is simple and could be useful for predicting therapeutic outcomes and treatment-related adverse events.

(a) The correlation between CRP and the ALBI score (r=0.44, p<0.001). (b) Receiver operating curve analysis. The cutoff value of the ALBI score for CRP ≥1 mg/dL was -2.348; the area under the receiver operating curve was 0.736 (95% CI 0.670-0.803; specificity, 0.648; sensitivity, 0.746). The present cutoff value was close to that of mALBI grade 2a and 2b (i.e., -2.27) (TIF 750 KB)

(a) PFS in patients with BCLC early and intermediate stage according to the CRAFITY score. The median PFS in the patients with CRAFITY scores of 0, 1, and 2 points was 11.8 months (95% CI 7.0-NA), 7.8 months (95% CI 6.5-12.5), and 3.2 months (95% CI 0.8-9.7), respectively. The PFS was significantly longer in the patients with a CRAFITY score of 0, followed by those with a CRAFITY score of 1, and those with a CRAFITY score of 2 points (p<0.001). (b) The PFS in patients with BCLC advanced and terminal stage according to CRAFITY score. The median PFS in the patients with CRAFITY scores of 0, 1, and 2 points was 6.8 months (95% CI 5.1-NA), 5.3 months (95% CI 3.5-7.6), and 3.0 months (95% CI 1.8-4.6), respectively, which amounted to a statistically significant difference (p=0.011). (c) The PFS in patients receiving Atez/Bev as front-line treatment according to CRAFITY score.

The median OS in patients with CRAFITY score 0 was not reached and it was 14.3 months (95% CI 10.0-NA) in patients with CRAFITY score 1 and 11.9 months (95% CI 1.57-NA) in patients with CRAFITY score 2, which amounted to a statistically significant difference (p=0.030). The 6-month and 12-month OS rates were 96.3% (95% CI 85.8-99.1) and 89.9% (95% CI 74.3-96.2), respectively, in patients with CRAFITY score 0, 92.3% (95% CI 78.1-97.5) and 58.6% (95% CI 35.7-75.8) in patients with CRAFITY score 1, and 78.7% (95% CI 38.1-94.3) and 39.4% (95% CI 5.9-73.6) in patients with CRAFITY score 2.

The median OS was not reached in patients with CRAFITY scores of 0 and 1, while it was 7.6 months (95% CI 4.4-NA) in patients with CRAFITY score of 2; this difference was statistically significant (p<0.001). The 6-month and 12-month OS rates were 92.9% (95% CI 82.1-97.3) and 74.3% (95% CI 51.4-87.6), respectively, in patients with CRAFITY score of 0, 93.3% (95% CI 83.2-97.4) and 67.6% (95% CI 46.8-81.7) in patients with CRAFITY score of 1, and 57.7% (95% CI 35.1-74.9) and 46.6% (95% CI 24.7-65.9) in patients with CRAFITY score of 2.
