Please note this is a comparison between Version 3 by Dean Liu and Version 2 by Dean Liu.

Hepatocellular carcinoma (HCC) is a leading cause of death worldwide. Selection of therapeutic modalities and the prognosis of affected patients are well known to be dependent not only on tumor burden, but also hepatic reserve function. Anti-viral treatments for chronic hepatitis related to a viral infection and an increase in cases of non-viral HCC associated with the aging of society have resulted in dramatic changes regarding the characteristics of HCC patients. With recent developments in therapeutic modalities for HCC, more detailed assessment of hepatic function has become an important need. Studies in which the relationship of albumin-bilirubin (ALBI) with prognosis of HCC patients was investigated were reviewed in order to evaluate the usefulness of newly developed ALBI and modified ALBI (mALBI) grades for HCC treatment, as those scoring methods are considered helpful for predicting prognosis and selecting therapeutic modalities based on expected prognosis.

1. Introduction

Hepatocellular carcinoma (HCC) is a leading cause of death worldwide[1][2]. In addition to liver transplantation, surgical resection, radiofrequency ablation (RFA), transarterial catheter chemoembolization (TACE), and tyrosine kinase inhibitors (TKIs) have been developed as standard treatments for each stage. It is well known that the prognosis of HCC patients is dependent not only on tumor burden but also hepatic reserve function[3][4][5].

The present review is conducted to focus on the useful predictive value of a newly developed assessment tool of hepatic function for prognosis with each modality for the treatment of patients with HCC.

1.1. Child–Pugh Classification as a Traditional Assessment Tool for Hepatic Function and Rapid Changes of Clinical Environment

Traditionally, the Child–Pugh classification has been used worldwide for a long period as a standard assessment tool for hepatic reserve function[6] because it is easy for clinicians to remember and calculate (Table 1).

Table 1. Comparisons of the Child–Pugh classification with ALBI and mALBI grades.

  Child-Pugh Classification ALBI/mALBI Grades
Total Bilirubin score 1: <2.0 mg/dL,

score 2: 2.0–3.0 mg/dL,

score 3: >3.0 mg/dL		 Used (µmol/L)
Albumin score 1: >3.5 g/dL,

score 2: 2.8–3.5 g/dL,

score 3: <2.8 g/dL		 Used (g/L)
Prothrombin time score 1: >70%,

score 2: 40–70%,

score 3: <40%		 No use
Ascites score 1: none,

score 2: mild/controlled,

score 3: moderate/refractory		 No use
Encephalopathy score 1: none,

score 2: minimal,

score 3: advanced		 No use
Calculation for score Sum up all scores and baseline score 5 log10 bilirubin (µmol/L) × 0.66) + (albumin (g/L) × –0.085
Classification A 5–6 score,

B 7–9 score,

C 10–15 score		 ALBI grade 1: ≤−2.60,

grade 2: >−2.60 to ≤−1.39, grade 3 >−1.39.mALBI grade 2a: >−2.60 to ≤−2.27.

grade 2b: >−2.27 to ≤−1.39.

ALBI grade: albumin-bilirubin grade; mALBI grade: modified ALBI grade.

The evidence-based clinical practice guideline for HCC of the Japan Society of Hepatology (JSH)[7] and Barcelona Clinic liver cancer staging system (BCLC) staging[8] therapeutic strategies for all HCC stages, and the subclassification for BCLC-B (intermediate) stage HCC for treatment guidance (Bolondi’s criteria[9] and Kindai criteria[10]) use Child–Pugh score/classification as an assessment method to evaluate the pretreatment hepatic reserve. In addition, clinical trends of HCC cases have shown dynamic changes. For example, the ability to treat the hepatic function of HCC patients affected by a hepatitis B virus (HBV) or hepatitis C virus (HCV) infection has shown improvement, because of the development of effective antiviral treatments (nucleotide analog for HBV, interferon therapy and direct acting antiviral agents for HCV). Moreover, there is an increasing number of HCC patients without HBV or HCV, which has become an important issue in association with the aging of society, as those often demonstrate good hepatic function[11][12]. As a result, in Japan, the percentage of HCC patients with Child–Pugh class A has increased from 52.1% in the 1990s to 84.8% in the late 2010s [13]. Moreover, some weak points of the Child–Pugh classification have been pointed out, including subjective factors (ascites, encephalopathy), interrelated factors (serum albumin level, ascites), semi-quantitative characteristics, and a lack of statistical evidence (Table 1).

1.2. A Development of New Assessment Tool for Hepatic Function: ALBI Grade

As noted above, the need for an objective and more detailed assessment tool, especially for patients with good hepatic function, has become an urgent issue. Recently, a simple and objective method for the evaluation of hepatic reserve function using only albumin and total-bilirubin measurements, termed albumin-bilirubin (ALBI) grade based on a formula (log10 bilirubin (µmol/L) × 0.66) + (albumin (g/L) × −0.085], has been proposed, with the values ≤−2.60, >−2.60 to ≤−1.39, and >−1.39 used to denote grades 1, 2, and 3, respectively [14]. Calculating only with two objective factors (bilirubin and albumin) is one of advantages because they are very common serum data and the frequency of a lack of data is low, especially in retrospective analyses. Following its development, it has been confirmed that ALBI grade can be used as an alternative assessment to the Child–Pugh classification, both in the evidence based clinical practice guideline for HCC of JSH (n = 3495)[15] and in the BCLC staging, with a weighted kappa value (which is a statistic for measuring the interevaluator reliability of qualitative items) of 0.917 noted with a multicenter cohort (n = 3696)[16]. As a result, ALBI grade has become recognized as a useful assessment tool for hepatic reserve function worldwide. However, a weak point of this grading system that has been pointed out is that grade 2 covers a wide range, similar to class B in the Child–Pugh classification. On the other hand, as opposed to the Child–Pugh score, which is a nominal variable, ALBI scoring has a great advantage as a continuous variable. To provide a more detailed assessment of hepatic reserve function, a modified ALBI (mALBI) grade has been proposed, with four grades including subgrades 2a and 2b, divided by the use of an ALBI score of −2.27 as the cutoff value for an indocyanine green retention rate at 15 min (ICG-R15) at 30%[17], because the ALBI score has been shown to have a correlation with ICG-R15 (r = 0.616, p < 0.001)[18]. The distribution of mALBI grades in comparison with Child–Pugh scores is shown in Figure 1 (1850 naïve HCC patients treated at Ehime Prefectural Central Hospital from 2000 to 2019). We consider that both ALBI and mALBI grades should be used for the assessment of hepatic function in patients, not only with early stage but also with intermediate and advanced stage HCC BCLC-B and -C, as they provide an opportunity to assess changes of hepatic function in detail during a clinical course (Figure 1).

2. Limitations of ALBI Grade

Although the ALBI score provides a good index for predicting complications following adult-to-adult living donor liver transplantation and has been shown to have a predictive ability similar to that of the Child–Pugh classification and MELD score, the weak points of the ALBI grade with regard to the prognostic predictive power of the decompensated cirrhosis status (especially with ascites) and ruptured HCC must be kept in mind. Many clinicians have a consensus that HCC patients with uncontrollable ascites are not eligible for aggressive treatments, except for liver transplantation. In a comparison of ALBI grade and MELD in patients undergoing transjugular intrahepatic portosystemic shunt (TIPS) creation due to portal hypertension complications (variceal bleeding 55%, ascites 35%, others 10%), Khabbaz et al. reported that only MELD was associated with a transplant-free survival, while it was also a better predictor of both 30-day and overall survival as compared to the ALBI grade (c-index: 0.74 vs. 0.64 and 0.63 vs. 0.59, respectively), while Kim et al. reported that the MELD-Na score could effectively identify hepatic function and prognosis in HCC patients with ascites when compared with ALBI, Child–Pugh and MELD scores]. Additionally, Wu et al. demonstrated that the Child–Pugh score could predict OS of patients with a ruptured HCC treated both with and without resection (all p < 0.0001), whereas the ALBI grade could not Needless to say, it is necessary to pay attention to the interpretation of the results in any assessment methods for hepatic reserve function in constitutional jaundice patients with an elevated bilirubin level including Gilbert’s syndrome.

3. Conclusions

ALBI and mALBI grades are worthy of clinical application for patients receiving treatments for HCC. With regards to predicting prognosis in those patients receiving curative as well as palliative treatments for u-HCC, a more detailed assessment of hepatic function provided by ALBI and mALBI grades can be used effectively in clinical situations. In the near future, the establishment of an HCC treatment algorithm using ALBI/mALBI grades is anticipated.
