The albumin-bilirubin grade uncovers the prognostic relationship between hepatic reserve and immune dysfunction in HIV-associated hepatocellular carcinoma

Albumin‑bilirubin grade is an independent prognostic factor for small lung cell cancer

Albumin-bilirubin (ALBI) grade was first described in 2015 as an indicator of liver dysfunction in patients with hepatocellular carcinoma. ALBI grade has been reported to have prognostic value in several malignancies including non-small cell lung cancer (NSCLC). The present study aimed to explore the prognostic impact of ALBI grade in patients with small cell lung cancer (SCLC). It retrospectively analyzed 135 patients with SCLC treated at Hebei General Hospital between April 2015 and August 2021. Patients were divided into two groups according to the cutoff point of ALBI grade determined by the receiver operating characteristic (ROC) curve: Group 1 with pre-treatment ALBI grade ≤-2.55 for an improved hepatic reserve and group 2 with ALBI grade >-2.55. Kaplan-Meier and Cox regression analysis were performed to assess the potential prognostic factors associated with progression free survival (PFS) and overall survival (OS). Propensity score matching (PSM) was applied to eliminate the influence of confounding factors. PFS and OS (P<0.001) were significantly improved in group 1 compared with in group 2. Multivariate analysis revealed that sex (P=0.024), surgery (P=0.050), lactate dehydrogenase (LDH; P=0.038), chemotherapy (P=0.038) and ALBI grade (P=0.028) are independent risk factors for PFS and that surgery (P=0.013), LDH (P=0.039), chemotherapy (P=0.009) and ALBI grade (P=0.013) are independent risk factors for OS. After PSM, ALBI grade is an independent prognostic factor of PFS (P=0.039) and OS (P=0.007). It was concluded that ALBI grade was an independent prognostic factor in SCLC.

Evaluation of Multiple Liver Cancer Scoring Systems

Liver cancer is one of the most common malignant tumors in the world, and its incidence and mortality are increasing year by year. The prognosis of liver cancer depends on the stage of liver cancer, the treatment method, the liver function, and individual differences. The prognosis of liver cancer mainly worsens with the progression of the stage. The prediction and staging system of liver cancer prognosis plays a very important role in the outcome of liver cancer prognosis, providing some guidance for clinical practice and bringing benefits for patients. This article reports on the prediction models and staging systems that have been applied in the field of liver cancer in the past 5 years, objectively analyzes the advantages and disadvantages, applicable population of each model and staging system, and searches for other patient and clinical characteristics that need to be considered for successfully establishing a prediction model, aiming to improve the specificity, sensitivity, and accuracy of liver cancer prediction and increase the overall survival rate of liver cancer.

Assessment of the albumin-bilirubin score in breast cancer patients with liver metastasis after surgery

Objective

This study aims to investigate the potential prognostic value of albumin-bilirubin (ALBI) score in breast cancer patients with liver metastasis after surgery.

Methods

This was a retrospective study of 178 breast cancer patients with liver metastasis after surgery. ALBI score was calculated by the following formula: (log10 bilirubin × 0.66) - (albumin × 0.085). The optimal cutoff value of ALBI score was assessed by X-tile. The clinical influence of ALBI score on survival outcomes using Kaplan-Meier method, Log-rank test, Cox proportional hazards regression model. The calibration curves, decision curve analysis and time-dependent ROC curve were used to assess the predictive performance of the nomogram's models.

Results

The classifications of 178 breast cancer patients with liver metastasis after surgery were as follows: low ALBI score group (＜-3.36) vs. high ALBI score group (≥-3.36). The Cox proportional hazards regression model indicated that ALBI score was a potential predictor. Kaplan-Meier survival curve performed that the median disease free survival (p = 0.0029) and overall survival (p＜0.0001) in low ALBI score group were longer than in high ALBI score group. The ALBI-based nomograms had good predictive performance.

Conclusions

The ALBI score has high prognostic ability for survival time in breast cancer with liver metastasis after surgery. These models will be valuable in discriminating patients at high risks of liver metastasis.

Integrated phenotyping of the anti-cancer immune response in HIV-associated hepatocellular carcinoma

Background & Aims

HIV-seropositivity shortens survival in patients with hepatocellular carcinoma (HCC). Although risk factors for HCC including HCV infection can influence T cell phenotype, it is unknown whether HIV can influence functional characteristics of the T cell infiltrate.

Methods

From the Liver Cancer in HIV biorepository, we derived 129 samples of transplanted (76%) or resected (20%) HCC in eight European and North American centres. We profiled intra- and peritumoural tissue to evaluate regulatory CD4+/FOXP3+ and immune-exhausted CD8+/PD1+ T cells in HIV+ (n = 66) and HIV- (n = 63) samples. We performed targeted transcriptomics and T-cell receptor sequencing in a restricted subset of samples evaluated in relationship with HIV status. We correlated immunopathologic features with patients' characteristics including markers of HIV infection.

Results

Of the 66 HIV+ patients, 83% were HCV coinfected with an undetectable HIV viral load (51%) and a median blood CD4+ cell count of 430 cells/mm³ (range 15-908). Patients who were HIV+ were compared with HIV- controls with similar staging characteristics including Barcelona Clinic Liver Cancer (BCLC) stage A-B (86% vs. 83%, p = 0.16), <3 nodules (90% vs. 83%, p = 0.3) and median alpha-foetoprotein values (10.9 vs. 12.8 ng/ml, p = 0.72). HIV+ samples had higher PD-L1 expression rates in tumour tissue (51% vs. 8% p <0.0001) and displayed denser intratumoural CD4+/FOXP3+ (p <0.0001), CD8+/PD1+ (p <0.0001), with lower total peritumoural CD4+ (p <0.0001) and higher peritumoural CD8+/PD1+ (p <0.0001). Gene set analysis revealed HIV+ cases to have evidence of dysregulated adaptive and innate immunity. Tumour-infiltrating lymphocyte clonality was not influenced by HIV status.

Conclusions

HIV-associated HCC harbours a profoundly immune-exhausted tumour microenvironment, warranting prospective testing of immunotherapy in this treatment-deprived patient population.

Impact and Implications

Hepatocellular carcinoma is a non-AIDS defining malignancy characterised by poor survival. The programmed cell death (PD-1) pathway governs antiviral and anticancer immune exhaustion and is a therapeutic target in HCC. This study highlights how HIV infection is associated with significantly higher PD-L1 expression in HCC cells and in the surrounding microenvironment, leading to changes in cytotoxic and regulatory T cell function and dysregulation of proinflammatory pathways. Taken together, our results suggest dysfunctional T cell immunity as a mechanism of worse outcome in these patients and suggest clinical testing of checkpoint inhibitors in HIV-associated HCC.

Survival in People Living with HIV with or without Recurrence of Hepatocellular Carcinoma after Invasive Therapy

Background and Aims: To address the overall survival (OS) and recurrence (RE) in people living with HIV (PLWH) treated with invasive therapy (IT) for hepatocellular carcinoma (HCC). Methods: This is a retrospective cohort study on 41 PLWH with HCC receiving IT, defined as liver resection (LR), orthotopic liver transplantation (OLT), radiofrequency thermo-ablation (RFTA) trans arterial chemo, or radioembolization (CRE). OS and RE were investigated by Kaplan–Meier curves. The Cox proportional hazard regression model was used for multivariate analyses. Results: Recurrence occurred in 46.3% PLWH; in 36.7% of participants at 2 years and in 52% at 5 years from HCC diagnosis; it was less frequent in males, p = 0.036. Overall, 2- and 5-year survival after HCC diagnosis was 72% and 48%, respectively. Two-and five-year survival was 100% and 90.9%, respectively, in PLWH receiving OLT, compared to other IT (60.9% and 30.6%, respectively) log-rank p = 0.0006. Two- and five-year survival in participants with no-RE was 70.5% and 54.6%, respectively, and 73.7% and 42.1% among RE, respectively, log-rank p = 0.7772. By multivariate analysis, AFP at values < 28.8 ng/mL, at HCC diagnosis, was the only factor predicting survival. Conclusions: Fifty percent of PLWH survived five years after HCC diagnosis; 90.9% among OLT patients. Recurrence after IT was observed in 46% of HCC/PLWH. AFP cut-off levels of 28.8 ng/mL were the only independent variable associated with survival.

A simple CD4+ T cells to FIB-4 ratio for evaluating prognosis of BCLC-B hepatocellular carcinoma: a retrospective cohort study

Introduction

Immunotherapy has become a new therapy for advanced hepatocellular carcinoma (HCC); however, its treatment results are considerably different. CD4+ T cells (CD4+) are the key to immunotherapy, but patients with HCC that have low CD4+ are rarely observed for clinical evidence. Hepatitis B virus-related HCC is often accompanied by cirrhosis and portal hypertension; therefore, CD4+ tend to be relatively low in number. TACE is the standard treatment for Barcelona Clinic Liver Cancer (BCLC)-B HCC, which may further reduce the number of CD4 + .

Methods

This retrospective cohort study further reduced CD4+ by including patients with human immunodeficiency virus (HIV) to observe the relationship between CD4+ and Chronic hepatitis B virus (CHB) induced HCC. A total of 170 BCLC-B HCC patients (42 HIV+) were included. Univariate and multivariate analyses, and artificial neural networks (ANNs) were used to evaluate the independent risk factors for the two-year survival.

Results

The statistical analysis of the two-year survival rate showed that the main factors influencing survival were liver function and immune indices, including CD4+, platelet, alanine aminotransferase, aspartate aminotransferase, aspartate aminotransferase-to-platelet ratio index, and fibrosis-4 (FIB-4) (P < 0.05). Compared with that in other indices, in logistic and ANN multivariate analysis, CD4 + -to-FIB-4 ratio (CD4+/FIB-4) had the highest importance with 0.716 C-statistic and 145.93 cut-off value. In terms of overall survival rate, HIV infection was not a risk factor (P = 0.589); however, CD4+/FIB-4 ≤ 145.93 significantly affected patient prognosis (P = 0.002).

Conclusion

HIV infection does not affect the prognosis of BCLC-B HCC, but CD4+ have a significant predictive value. CD4+ played a vital role in HCC and this deserves the attention from physicians. Further, the CD4+/FIB-4 is a clinically valuable effective prognostic indicator for these patients.

Outcome of TACE treatment in HIV infected patients with hepatocellular carcinoma

The surgical treatment and transcatheter arterial chemoembolization (TACE) rate of human immunodeficiency virus (HIV)-infected hepatocellular carcinoma (HCC) patients is relatively low in West China. For various reasons, most patients do not receive timely surgical treatment. Upon transfer to an infectious disease centralized hospital, they were already classified in the Barcelona Clinic Liver Cancer (BCLC)-B stage. A total of 2249 BCLC-B HCC patients were analyzed. The eligible population was divided into three groups for analysis of survival and prognostic factors; These were 21 HIV infected (HIV+) HCC patients treated with TACE (TACE+), 1293 non-HIV-infected (HIV−) HCC patients treated with TACE, and 150 HIV− HCC patients who only receive medication (TACE−) as a second control group. After 1:2 matching, 1- and 2-year survival of HIV+ TACE+ and HIV− TACE+ groups was 64.3% and 76.5% (P = 0.453) and 45.5% vs. 50.0% (P = 0.790) respectively. We also compared one and two-year survival between HIV+ TACE+ and HIV− TACE−. One-year overall survival was 64.3% vs. 45.7% (P = 0.097) and 2-year survival was 45.5% vs. 7.1% (P = 0.004). Multivariate analysis showed that the most important prognostic factors for survival were serum alpha-fetoprotein (AFP) and Child–Pugh score and tumor size, while HIV status had no significant effect on prognosis statistically. CD4 levels below 200 may increase the risk of opportunistic infection after surgery, but after anti-infection and systematic supportive therapy, it has no effect on survival. HIV+ patients should have the same treatment opportunities as HIV− patients. If the patient's immune status permits, we suggest that early TACE treatment should be administered to BCLC-B HCC patients, regardless of HIV infection.

The impact of HIV on hepatocellular cancer survival in Nigeria

BACKGROUND

Hepatocellular carcinoma (HCC) is an increasing cause of mortality in HIV-infected individuals. We compared host and tumour characteristics between HIV-infected and HIV-uninfected Nigerians with HCC and examined the impact of HIV on survival.

METHODS

This prospective observational study was conducted at Jos University Teaching Hospital in Jos, Nigeria, among adults (>18 years) with HCC enrolled between September 2015 and September 2017 and followed until April 2019. Demographics, tumour characteristics and survival were compared between HCC subjects with and without HIV.

RESULTS

101 (10 HIV-infected and 91 HIV-uninfected) subjects were enrolled [male 72%; median age 48 (IQR 35-60)]. 60% HIV-infected subjects were receiving ART; 90% had CD4 counts ≥ 200/mm³ at HCC diagnosis, and 20% had HIV RNA levels < 20 copies/mL. 57.4% were infected with chronic HBV (HBsAg+). The duration of symptoms was shorter in HIV-infected vs. HIV-uninfected subjects [93 (IQR 54-132) vs. 155 (93-248] days; p = 0.02]. At the end of follow-up, 99 of 101 (98.0%) subjects were confirmed to have died: 9 of 10 (90.0%) HIV-infected and 90 of 91 (98.9%) HIV-uninfected. The probability of survival at three months was 22% and 47% in HIV-infected and HIV-uninfected subjects, respectively (P = 0.02). Median time to death was significantly shorter in HIV-infected vs. HIV-uninfected subjects [24 days (IQR 16-88) vs. 85 days (IQR 34-178), respectively (P = 0.03)].

CONCLUSIONS

High early mortality was observed in this cohort of Nigerian adults with HCC. HIV infection was associated with a faster clinical presentation and shorter survival. More aggressive HCC surveillance may be warranted in HIV-infected subjects, particularly if they are co-infected with chronic HBV.

Assessment of the Outcomes of Intrahepatic Cholangiocarcinoma After Ultrasound-Guided Percutaneous Microwave Ablation Based on Albumin-Bilirubin Grade

OBJECTIVE

To determine whether albumin-bilirubin (ALBI) grade could be used to predict the outcomes of patients with intrahepatic cholangiocarcinoma (ICC) who underwent ultrasound-guided percutaneous microwave ablation (MWA).

MATERIALS AND METHODS

This retrospective study was approved by the institutional review board, and the requirement for informed consent was waived. We studied 52 treatment-naïve patients with 74 ICC lesions according to the Milan criteria who subsequently underwent MWA from April 2011 to March 2018. Overall survival (OS) and recurrence-free survival (RFS) were compared in groups classified by Child-Pugh score and ALBI grade, which were statistically analyzed with the log-rank test. Cox proportional hazard regression analyses were used to determine the prognostic factors for survival in patients with ICC.

RESULTS

The median follow-up time was 21.2 months (3.2-78.7 months). Seventeen patients died during this period. After MWA, the cumulative 1-, 3-, and 5-year OS rates were 87.4%, 51.4%, and 35.2%, respectively, and the cumulative 1-, 3-, and 5-year RFS rates were 68.9%, 56.9%, and 56.9%, respectively. The major complication rate was 3.8% (2/52). Stratified according to ALBI grade, the cumulative 1-, 3-, and 5-year OS rates were 95.5%, 72.4%, and 72.4% for patients with ALBI grade 1 and 62.5%, 40.6%, and 36.3% for patients with ALBI grade 2, respectively, showing a significant difference (P = 0.006). Multivariate analysis results showed that older age (hazard ratio [HR]: 1.67, 95% confidence interval [CI]: 1.11-2.82; P = 0.002), tumor size ≥ 3 cm in diameter (HR: 11.33, CI: 2.24-34.52; P = 0.021) and ALBI grade (HR: 8.23, CI: 1.58-58.00; P = 0.004) may be predictors of poor OS.

CONCLUSION

ALBI grade was validated as a significant biomarker for predicting survival in ICC patients within the Milan criteria who underwent MWA.

Neutrophil to lymphocyte ratio and albumin bilirubin grade in hepatocellular carcinoma: A systematic review

BACKGROUND

Hepatocellular carcinoma (HCC) is a frequent cause of cancer related death globally. Neutrophil to lymphocyte ratio (NLR) and albumin bilirubin (ALBI) grade are emerging prognostic indicators in HCC.

AIM

To study published literature of NLR and ALBI over the last five years, and to validate NLR and ALBI locally in our centre as indicators of HCC survival.

METHODS

A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years. The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses. Additionally, we also investigated HCC cases between December 2013 and December 2018 in our centre.

RESULTS

There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years. Our local cohort of patients showed NLR to have a significant negative relationship to survival (P = 0.011). There was also significant inverse relationship between the size of the largest HCC nodule and survival (P = 0.009). Median survival with alpha fetoprotein (AFP) < 10 KU/L was 20 mo and with AFP > 10 KU/L was 5 mo. We found that AFP was inversely related to survival, this relationship was not statically significant (P = 0.132). Mean survival for ALBI grade 1 was 37.7 mo, ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5 mo. ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.

CONCLUSION

NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein. ALBI grade performs better than Child Turcotte Pugh score. These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein, these markers could give a better understanding of the patient disease progression. NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.

Predictive value of the albumin-bilirubin grade on long-term outcomes of CT-guided percutaneous microwave ablation in intrahepatic cholangiocarcinoma

PURPOSE

To assess the efficacy of the albumin-bilirubin (ALBI) grade on assessing long-term outcomes of computed tomography (CT)-guided percutaneous microwave ablation (CT-PMWA) in the treatment of patients with intrahepatic cholangiocarcinoma (ICC).

METHODS

Between April 2011 and March 2018, 78 patients who underwent CT-PMWA were enrolled in this study. Overall survival (OS) and recurrence-free survival (RFS) were compared in the groups stratified by the ALBI grade and Child-Pugh score. Cox proportional hazard regression analyses were performed to determine independent predictors of OS and RFS.

RESULTS

After a median follow-up of 22.7 months (range 1-86.7 months), 67 patients had died. The cumulative 1-, 3-, and 5-year OS rates were 89.5%, 52.2%, and 35.0%, respectively. Stratified by the ALBI grade, the cumulative 1-, 3-, and 5-year OS rates were 100%, 69.2%, and 25.6% for patients with the grade 1, respectively. For patients with the ALBI grade 2, the cumulative 1-, 3-, and 5-year OS rates were 41.0%, 10.3%, and 10.3%, respectively. Patients with a hepatic function of the ALBI grade 1 had significantly higher OS rates than patients with the ALBI grade 2 (p < .001). The multivariate analysis showed tumor size (Hazard Ratio[HR] 95% Confidence Interval[CI]:9.03[1.01-80.52], p = .049) and the ALBI grade (HR[95%CI]:9.56[1.58-58.00], p = .014) were associated with OS, and tumor size (HR: 2.03[0.69-8.04], p = .049) was associated with RFS.

CONCLUSIONS

The preliminary data of this study showed the ALBI grade was effective to predict long-term outcomes of CT-PMWA in ICCs. Further study is necessary to validate our results by a large, multi-center patient cohort.

Prognostic value of pretreatment albumin to bilirubin ratio in patients with hepatocellular cancer: A meta-analysis

BACKGROUND

Hepatic function is closely associated with prognosis in patients with hepatocellular cancer (HCC). In this study, a meta-analysis of the published studies was performed to assess the prognostic value of ALBI grade in HCC patients.

METHODS

Databases, including PubMed, EMbase, Web of Science, and Cochrane Library were retrieved up to August 2018. The primary outcome was OS and secondary outcome was DFS, the prognostic impact of which was assessed by using hazard ratio (HRs) with corresponding 95% confidence intervals (CIs). The enrolled studies were analyzed by using STATA version 12.0 software.

RESULTS

A total of 22,911 patients with HCC in 32 studies were included. Our results demonstrated that high pretreatment ALBI is associated with poor OS (HR = 1.719, 95%CI: 1.666-1.771, P = .000, univariate results; HR = 1.602, 95%CI: 1.470-1.735, P = .000, multivariate results) and poor DFS (HR = 1.411, 95%CI: 1.262-1.561, P = .000, univariate results; HR = 1.264, 95%CI: 1.042-1.485, P = .000, multivariate results). Meanwhile, when the analysis was stratified into subgroups, such as treatment methods, sample size, geographic area, and ALBI grade, the significant correlation in ALBI and poor long-term survival was not altered.

CONCLUSION

High pretreatment ALBI is closely associated with poor prognosis in HCC, and High ALBI should be treated as an ideal predictor during hepatocellular therapy.

Influence of HIV Infection on the Natural History of Hepatocellular Carcinoma: Results From a Global Multicohort Study

PURPOSE

Conflicting evidence indicates that HIV seropositivity may influence the outcome of patients with hepatocellular carcinoma (HCC), a leading cause of mortality in people with HIV. We aimed to verify whether HIV affected the overall survival (OS) of patients with HCC, independent of treatment and geographic origin.

PATIENTS AND METHODS

We designed an international multicohort study of patients with HCC accrued from four continents who did not receive any anticancer treatment. We estimated the effect of HIV seropositivity on patients' OS while accounting for common prognostic factors and demographic characteristics in uni- and multivariable models.

RESULTS

A total of 1,588 patients were recruited, 132 of whom were HIV positive. Most patients clustered within Barcelona Clinic Liver Cancer (BCLC) C or D criteria (n = 1,168 [74%]) and Child-Turcotte-Pugh (CTP) class B (median score, 7; interquartile range [IQR], 3). At HCC diagnosis, the majority of patients who were HIV-positive (n = 65 [64%]) had been on antiretrovirals for a median duration of 8.3 years (IQR, 8.59 years) and had median CD4⁺ cell counts of 256 (IQR, 284) with undetectable HIV RNA (n = 68 [52%]). OS decreased significantly throughout BCLC stages 0 to D (16, 12, 7.5, 3.1, and 3 months, respectively; P < .001). Median OS of patients who were HIV-positive was one half that of their HIV-uninfected counterparts (2.2 months [bootstrap 95% CI, 1.2 to 3.1 months] v 4.1 months [95% CI, 3.6 to 4.4 months]). In adjusted analyses, HIV seropositivity increased the hazard of death by 24% ( P = .0333) independent of BCLC ( P < .0001), CTP ( P < .0001), α-fetoprotein ( P < .0001), geographical origin ( P < .0001), and male sex ( P = .0016). Predictors of worse OS in patients who were HIV-positive included CTP ( P = .0071) and α-fetoprotein ( P < .0001).

CONCLUSION

Despite adequate antiretroviral treatment, HIV seropositivity is associated with decreased survival in HCC, independent of stage, anticancer treatment, and geographical origin. Mechanistic studies investigating the immunobiology of HIV-associated HCC are urgently required.
