Simple Scoring System for Predicting TACE Unsuitable among Intermediate-Stage Hepatocellular Carcinoma Patients in the Multiple Systemic Treatment Era

BACKGROUND/AIM

With the development of systemic treatment methods for unresectable hepatocellular carcinoma (uHCC), the concept of unsuitable for transcatheter arterial chemoembolization (TACE) has become important. This study aimed to establish a simple predictive scoring system for determining TACE unsuitable status.

MATERIALS/METHODS

From 1998 to 2015, 196 patients with intermediate-stage uHCC with Child-Pugh A (score 5:6 = 108:88) and given TACE as the initial treatment were enrolled. At the baseline, tumor burden (Milan criteria-out, up-to-7 in/out, and up-to-11 in/out: 0-2 points) and modified albumin-bilirubin grade 1/2a or 2b (0-1 point) were added to determine the score for TACE unsuitable (CITRUS-MICAN score; low <2 and high ≥2). In addition, a previously reported tumor marker (TM) score, in which alpha-fetoprotein (AFP) was ≥100 ng/mL, fucosylated AFP ≥10%, and des-gamma-carboxy prothrombin ≥100 mAU/mL (each 1 point) (total 0, 1, or ≥2 points), was used for additionally evaluating tumor malignancy potential. Prognosis was retrospectively evaluated based on those scores.

RESULTS

Median survival time (MST) was better for low compared to high CITRUS-MICAN score (42.0 vs. 26.4 months) (p = 0.002). A 2-step evaluation using the combination of CITRUS-MICAN and TM scores showed an MST of 43.2 months for low CITRUS-MICAN/TM score 0/1 (rank-A) and 39.6 months for low CITRUS-MICAN/TM score ≥2 (rank-B2), while it was 46.8 months for high CITRUS-MICAN/TM score 0 (rank-B1), 28.8 months for high CITRUS-MICAN/TM score 1 (rank-B2), and 22.8 months for high CITRUS-MICAN/TM score ≥2 (rank-C). For rank-A cases (n = 51), MST was 43.2 months, while it was 46.8 months for rank-B1 (n = 12), 31.2 months for rank-B2 (n = 82), and 22.8 months for rank-C (n = 51) (p = 0.001).

CONCLUSION

The results showed that rank-C indicates absolute TACE unsuitable status. For rank-A patients, good prognosis with TACE can be expected, while TACE refractoriness status during the clinical course should be carefully evaluated so as to anticipate the appropriate timing for switching to systemic treatment in rank-B1 and -B2 patients.

A case of conversion hepatectomy for huge ruptured hepatocellular carcinoma after transarterial embolization and lenvatinib therapy

We herein report a successfully treated case of huge ruptured hepatocellular carcinoma (HCC) by conversion hepatectomy after transarterial embolization (TAE) and lenvatinib therapy. A 33-year-old male patient with right hypochondralgia and liver tumor was referred to our hospital. He had a history of surgery for heart malformation. The tumor at the right lobe was 15 cm in diameter with bloody ascites. Right atrial thrombus 4.5 cm in diameter and marked cardiac dilatation were observed. TAE with ethanol suspended in lipiodol and gelatin sponge achieved hemostasis of the ruptured HCC. Although viable HCC remained after TAE, surgical treatment was abandoned because of abdominal wall invasion and his heart function. Lenvatinib and rivaroxaban were then initiated for HCC and atrial thrombus, respectively. Lenvatinib treatment resulted in a reduction in tumor marker levels and the tumor size. First, we planned conversion hepatectomy after 5 months of lenvatinib. However, recurrence of atrial thrombus prompted us to put off the surgery, and lenvatinib was re-administered. After improvement of atrial thrombus, we finally performed conversion hepatectomy 10 months after starting lenvatinib administration. The tumor was completely removed by combined resection of the diaphragm, and the patient has been doing well without any signs of recurrence.

An Autopsy Case of Multicentric Castleman Disease Presenting with Severe Jaundice

A 70-year-old man with multicentric Castleman disease (MCD) was admitted to our hospital with jaundice and ascites. Elevations in his bilirubin and interleukin-6 levels were noted, and computed tomography revealed hepatic atrophy and portal vein and bile duct disorders. Steroid therapy was started for MCD, but he died of hepatic failure. An autopsy revealed that the MCD activity was mild, but advanced fibrosis and cholestasis were observed in the liver. Mild infiltration of interleukin-6-positive plasma cells was noted in the highly fibrotic area of the liver. Although rare, liver and biliary tract damage may be also considered organ disorders of MCD.

Androgen receptor phosphorylated at Ser815: The expression and function in the prostate and tumor-derived cells

Androgen is beneficial for the prostate with normal functions but creates a risk for prostate cancer progression. How androgen receptor (AR) mediates these various androgen actions remains elusive. AR conserves a phosphorylation motif within its ligand-binding domain throughout species. Here, we have found AR phosphorylated at Ser815 (P-AR) is expressed in normal tissues of both human and mouse prostates. P-AR begins expression in association with prostatic development and castration decreases its expression levels in the mouse prostate. Functional analysis of AR in prostate cancer PC-3 cells showed ligand-induced AR nuclear translocation and transactivation were disturbed by its phosphorylation at Ser815. Moreover, P-AR suppressed oncogenic AKT signaling suggesting a suppressive function for prostate cancer development. In fact, AR phosphorylation levels progressively decrease in human prostates as cancer worsens. These findings showed androgen might utilize P-AR to self-antagonize oncogenic signals and cancer progression believed to be regulated by non-phosphorylated AR (NonP-AR). By differing its target genes and signal regulations from those of NonP-AR, P-AR co-expression with NonP-AR may be the molecular basis for androgen to balance its actions and to control disease developments.

Successful treatment of Japanese hemophilia patient co-infected with HIV and HCV genotype 4a by glecaprevir/pibrentasvir therapy

Although direct-acting antiviral (DAA)-based anti-hepatitis C virus (HCV) therapies are very effective for patients with genotypes 1 and 2, evidence of the efficacy of DAA-based therapy for the special population of patients with genotypes 3-6 is insufficient due to the relatively small number of these subjects in Japan. Human immunodeficiency virus (HIV)/HCV-co-infected patients are recommended to be treated as HCV-mono-infected patients by the latest version of the Japan Society of Hepatology guidelines. However, evidence of efficacy in patients with HIV/HCV genotype 3-6 co-infection is insufficient. Currently, HCV genotypes 3-6 can be treated with two DAA-based therapies, including glecaprevir (GLE)/pibrentasvir (PIB) therapy in Japan. We experienced a relatively rare case of a Japanese hemophilia patient co-infected with HIV/HCV genotype 4a. We evaluated resistance-associated substitutions (RASs) against GLE and PIB before GLE/PIB therapy and found that he had no RASs. He was treated with 12 weeks of GLE/PIB therapy and achieved a sustained virologic response at post-treatment weeks 24. Although the treatment was well tolerated, the patient developed hyper-low-density lipoproteinemia that was probably associated with HCV elimination during the therapy. Additional studies are needed to confirm the efficacy and safety of GLE/PIB therapy for this special population in Japan.

Effect of 48-week pemafibrate on non-alcoholic fatty liver disease with hypertriglyceridemia, as evaluated by the FibroScan-aspartate aminotransferase score

Background and Aim

This retrospective study investigated the effect of 48‐week pemafibrate therapy in non‐alcoholic fatty liver disease (NAFLD) with hypertriglyceridemia, as evaluated by the FibroScan‐aspartate aminotransferase (FAST) score.

Methods

A total of 31 NAFLD patients who were treated with pemafibrate in Gunma Saiseikai Maebashi Hospital and Kusunoki Hospital from September 2018 to April 2020 were included in the current study. We used the FAST score, which is a novel index of steatohepatitis that can be calculated based on the AST value, controlled attenuation parameter (CAP), and liver stiffness measurement (LSM), to evaluate the effect of pemafibrate treatment.

Results

The median age was 64.0 (interquartile range [IQR] 55.0–75.0) years and 14 patients (45.2%) were male. Median body mass index was 26.8 (IQR 23.8–28.8). Hypertension and diabetes mellitus were detected in 14 (45.2%) and five (16.1%) patients, respectively. Fasting triglyceride and high‐density lipoprotein cholesterol were significantly improved (P < 0.001 and 0.013, respectively) and the AST, alanine aminotransferase (ALT), alkaline phosphatase, and γ‐glutamyl transpeptidase values were significantly decreased during pemafibrate treatment (P = 0.041, <0.001, <0.001, and <0.001, respectively). While the LSM value and CAP value did not differ to a statistically significant extent (P = 0.19 and 0.140, respectively), the FAST score was significantly improved during pemafibrate treatment (P = 0.029). The delta FAST score was found to be correlated with the variations of ALT (r = 0.504, P = 0.005), which represents the effect of pemafibrate.

Conclusions

Pemafibrate improved the FAST score due to the hepatic anti‐inflammatory effect, indicating that pemafibrate may prevent disease progression in NAFLD patients with hypertriglyceridemia.

Lenvatinib for Hepatocellular Carcinoma Patients with Nonviral Infection Who Were Unlikely to Respond to Immunotherapy: A Retrospective, Comparative Study

AIM

Atezolizumab plus bevacizumab (atezo + bev) shows a good overall survival (OS) in advanced hepatocellular carcinoma (HCC) patients. However, the OS of patients with nonviral infection is quite worse than that in those with viral infection. The present study investigated the efficacy and safety of lenvatinib in patients with nonviral infection, who were unlikely to obtain benefit from atezo + bev.

METHODS

We conducted a multicenter retrospective study that included 139 advanced HCC patients treated with lenvatinib between March 2018 and September 2020.

RESULTS

The median age was 72 years, and 116 patients (83.5%) were male. Based on the etiology of liver disease, 84 (60.4%) and 55 patients (39.6%) were assigned to the viral infection and nonviral infection groups, respectively. The significant extents in patient characteristics were not observed in both groups. The objective response rate per mRECIST and progression-free survival (PFS) did not differ significantly between the viral infection and nonviral infection groups (36.0 vs. 33.0%, p = 0.85; and 7.6 vs. 7.5 months, p = 0.94, respectively). The 1-year survival rates were 68.7% (95% confidence interval [CI] 57.7-79.7%) in the viral infection group and 59.5% (95% CI 45.2-73.8%) in the nonviral infection group. The viral infection group was not a significant factor associated with the PFS or OS in a multivariate analysis.

CONCLUSIONS

Lenvatinib shows no significant difference in response between patients with and without viral infection. Treatment strategies based on the etiology of liver disease may lead to good clinical outcome.

Therapeutic efficacy of lenvatinib as third-line treatment after regorafenib for unresectable hepatocellular carcinoma progression

AIM

Multiple molecular agents have been developed for treating unresectable hepatocellular carcinoma. This study aimed to elucidate the clinical efficacy of sequential treatment with lenvatinib after regorafenib failure.

METHODS

From June 2017 to October 2020, 63 patients with Child-Pugh A and treated with regorafenib followed by sorafenib were enrolled (median age 71 years, 52 men, Barcelona Clinic Liver Cancer B:C = 23:40). They were divided into two groups, those treated with lenvatinib after regorafenib treatment (R-L group, n = 47) and those who did not receive lenvatinib after regorafenib (non-R-L group, n = 16). Prognostic factors were retrospectively analyzed after adjustment with inverse probability weighting.

RESULTS

Serum albumin level at the start of regorafenib and reasons for discontinuation of regorafenib were significantly different between the R-L and non-R-L groups, whereas the albumin-bilirubin score, Child-Pugh class, and tumor burden were not. Progression-free survival was also not significantly different (median 4.1 vs. 3.8 months, p = 0.586). As for overall survival, the R-L group showed better prognosis after introducing regorafenib and after introducing sorafenib, following inverse probability weighting adjustment (MST 19.7 vs. 10.3 months, 33.8 vs. 15.3 months, p < 0.001 and p = 0.022, respectively). Modified albumin-bilirubin grade 2b (score >-2.27) at the start of regorafenib (HR 2.074, p = 0.041) and the presence of lenvatinib treatment after regorafenib failure (HR 0.355, p = 0.004) were found to be significant prognostic factors in Cox proportional hazards multivariate analysis, after inverse probability weighting adjustment.

CONCLUSION

These results show that lenvatinib is a good sequential treatment option after progression under regorafenib therapy in unresectable hepatocellular carcinoma patients with better hepatic reserve function.

Impact of Pemafibrate in Patients with Hypertriglyceridemia and Metabolic Dysfunction-associated Fatty Liver Disease Pathologically Diagnosed with Non-alcoholic Steatohepatitis: A Retrospective, Single-arm Study

Objective The therapeutic effect of pemafibrate on metabolic dysfunction-associated fatty liver disease (MAFLD) remains unknown. This retrospective, single-arm study investigated the efficacy and safety of pemafibrate in MAFLD patients with hypertriglyceridemia. Methods A total of 10 patients who received pemafibrate (oral, 0.1 mg, twice a day) at Gunma Saiseikai Maebashi Hospital between September 2018 and September 2019 were included. All patients underwent a liver biopsy, and the disease grade and stage were pathologically assessed based on the FLIP algorithm. Results The median age was 66.0 (53.8-74.8) years old, and 5 patients (50.0%) were men. All patients were diagnosed with non-alcoholic steatohepatitis (NASH). The fasting and non-fasting triglyceride (TG) levels were 175 (149-247) mg/dL and 228 (169-335) mg/dL, respectively. The AST and ALT values at 6 months were significantly lower than at baseline [AST: 28.0 (22.0-33.8) U/L vs. 43.5 (24.0-55.0) U/L, p=0.008, ALT: 23.0 (14.8-26.5) U/L vs. 51.5 (23.0-65.3) U/L, p=0.005, respectively], especially in NASH patients with significant activity and advanced fibrosis (p=0.040 and 0.014, respectively). Fasting TG levels were significantly lower and HDL-C levels significantly higher at 6 months than at baseline (p=0.005 and 0.032, respectively). At six months, FIB-4, the aspartate aminotransferase-to-platelet ratio index, and the macrophage galactose-specific lectin-2 binding protein glycosylation isomer level were significantly improved compared with baseline (p=0.041, 0.005 and 0.005, respectively). Treatment-related adverse events were not observed. Conclusion Pemafibrate treatment may be safe and effective for MAFLD patients with hypertriglyceridemia.

Guillain-Barré syndrome after SARS-CoV-2 infection

We herein report a case of Guillain‐Barré syndrome (GBS) after SARS‐CoV‐2 infection. The patient was a close contact with a SARS‐CoV‐2 patient. Initially, she did not have any symptoms and quarantined at a hotel. Dysgeusia and olfactory abnormality appeared at day 6 after testing positive for infection and disappeared by day 9. Subsequently, the patient developed numbness of the arms and legs, difficulty walking, and dyspnea and was referred to our hospital. Her clinical examination showed generalized weakness and hyporeflexia. A cerebrospinal fluid analysis showed albuminocytological dissociation. Her nerve conduction studies were consistent with demyelinating polyneuropathy. Intravenous immunoglobulin was administered based on a diagnosis of GBS.

The first reported case of Noonan syndrome complicated with hepatocellular carcinoma

Noonan syndrome is a genetic multisystem disorder and is associated with mutation of genes encoding the proteins in the RAS-MAPK pathway. We reported the first case of Noonan syndrome complicated with hepatocellular carcinoma.

Impact of M2BPGi on the Hepatocarcinogenesis after the Combination Therapy with Daclatasvir and Asunaprevir for Hepatitis C

The clinical significance of mac-2 binding protein glycosylation isomer (M2BPGi) levels based on virological responses due to antiviral therapy has not been fully evaluated. We compared the change before and 24 weeks after the therapy with daclatasvir and asunaprevir (DCV+ASV) of M2BPGi levels with those of other fibrosis markers in 73 chronic hepatitis C cases. Moreover, we examined the association between M2BPGi levels and hepatocarcinogenesis in sustained virological response (SVR) and non-SVR cases. M2BPGi levels were significantly improved at post-treatment week 24 (PTW24) in SVR but not non-SVR cases, whereas the changes of other fibrosis markers showed the same tendency in both SVR and non-SVR cases. M2BPGi levels were well correlated with other fibrosis markers at baseline but not PTW24. The incidence of hepatocellular carcinoma (HCC) was significantly associated with M2BPGi levels at PTW24. The achievement of SVR significantly affected the improvement of M2BPGi levels that best reflected the effect of direct-acting antivirals among the fibrosis markers. Furthermore, M2BPGi levels at PTW24 were also associated with the incidence of HCC in only SVR cases. However, the rapid decrease of M2BPGi levels might reflect the amelioration of liver inflammation rather than the improvement of liver fibrosis, which should be further elucidated.

Successfully Treated Case of Cholangiolocellular Carcinoma with a Poor Hepatic Functional Reserve Reporting with Various Imaging Findings

Cholangiolocellular carcinoma (CoCC) is a rare primary liver cancer that is difficult diagnose due to a lack of specific imaging findings. We herein report a case of CoCC accompanied by severe alcoholic cirrhosis. Dynamic computed tomography showed a low-density tumor with a faint surrounding enhancement. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging revealed iso-intensity in the hepatobiliary phase and a maximum tumor diameter of 53 mm. ¹⁸F-fluoro-2-deoxyglucose position-emission tomography was moderately positive (maximum standardized uptake value: 4.3). CoCC was diagnosed based on the pathological findings, including immunohistochemistry. We discuss the diagnostic imaging findings and review previous reports.

Carbon ion radiotherapy for patients with hepatocellular carcinoma in the caudate lobe carbon ion radiotherapy for hepatocellular carcinoma in caudate lobe

AIM

The treatment of hepatocellular carcinoma in the caudate lobe (HCCCL) is technically challenging. We aimed to investigate the efficacy and toxicity of carbon ion radiotherapy (C-ion RT) for HCCCL.

METHODS

Patients with HCCCL treated with C-ion RT at our hospital between January 2011 and December 2018 were evaluated. The total dose was 52.8 or 60 Gy (relative biological effectiveness) in four or 12 fractions depending on the distance between the tumor and the gastrointestinal tract. The survival outcome, the presence or absence of recurrence (local recurrence, intrahepatic recurrence outside the irradiation field, or extrahepatic recurrence), and acute/late adverse events were evaluated.

RESULTS

Nine patients were included. The median tumor size was 3.4 cm, and the median follow-up duration was 18.3 months for all patients. No patient developed local recurrence during follow-up. Five patients subsequently developed intrahepatic recurrence outside the irradiation field and two had extrahepatic metastasis. Five patients died of hepatocellular carcinoma. No acute adverse events of grade ≥2 were observed. Two patients experienced grade 2 or 3 late adverse events, including obstructive jaundice, hepatic encephalopathy, ascites, and edema.

CONCLUSION

Carbon ion radiotherapy for HCCCL achieved excellent local control with acceptable adverse events and can thus be a curative treatment option for HCCCL.

Imatinib and nutritional support can make successful treatment for a case of huge liver metastasis of duodenal gastrointestinal stromal tumor that initially showed jaundice and cachexia

It is very difficult to treat patients with liver metastasis presenting with jaundice or cachexia. We herein report a successfully treated case of huge liver metastasis of gastrointestinal stromal tumor (GIST) that initially showed jaundice and cachexia. The patient was a woman in her early 40 s. She had a history of duodenal GIST 4 years before this admission. She was admitted to our hospital for abdominal fullness and anorexia. Abdominal computed tomography revealed huge liver metastasis of GIST. She showed jaundice and cancer cachexia with a modified Glasgow Prognostic Score of 2. After applying nutritional support, 400 mg of imatinib was administered. Although leg edema transiently worsened, the withdrawal of imatinib and administration of diuretics improved it. Imatinib was re-administered, and nutritional support was continued. The total bilirubin level decreased, and the serum albumin level increased. The tumor gradually decreased in size. Finally, she received surgical resection after 16 months of treatment with imatinib. Although adjuvant imatinib administration was continued after surgery, and no recurrence was observed as of 18 months after surgery.

Prognosis of late elderly patients with chronic hepatitis C after achieving a sustained viral response by direct-acting antivirals

Background and Aim

We investigated the prognosis of late elderly patients (≥75 years old) after the achievement of a sustained viral response (SVR) by direct‐acting antivirals (DAAs).

Methods

One hundred and four late elderly patients and 251 young patients (≤74 years old) who had achieved an SVR were included. We compared the cumulative hepatocellular carcinoma (HCC) incidence rates and survival rates after DAA administration. Furthermore, the factors associated with HCC incidence and the causes of death after DAA administration were also investigated.

Results

The cumulative HCC incidence rates for 1 and 3 years were 2.9% and 11.7% in the late elderly patients and 2.4% and 5.4% in the young patients, respectively. The cumulative survival rates for 1 and 3 years were 100% and 95.6% in the late elderly patients and 100% and 96.4% in the young patients, respectively, with no significant differences in those rates noted (P = 0.133, P = 0.322, respectively). In the late elderly patients, only a history of HCC was a significant factor associated with HCC incidence after DAA administration. Five late elderly patients died after achieving an SVR, and malignant liver tumor was the cause of death in three of those patients.

Conclusions

The prognosis did not differ markedly between late elderly patients and young patients. The factor most strongly influencing the prognosis of late elderly patients was likely liver disease, including HCC. DAAs should be introduced even in late elderly patients who can be expected to have a relative long‐term survival.

The influence of the long-term chemical activation of the nuclear receptor pregnane X receptor (PXR) on liver carcinogenesis in mice

Pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are nuclear receptors that are highly expressed in the liver and activated by numerous chemicals. While CAR activation by its activators, such as phenobarbital (PB), induces hepatocyte proliferation and liver carcinogenesis in rodents, it remains unclear whether PXR activation drives liver cancer. To investigate the influence of PXR activation on liver carcinogenesis, we treated mice with the PXR activator pregnenolone 16α-carbonitrile (PCN) with or without PB following tumor initiation with diethylnitrosamine (DEN). After 20 weeks of treatment, preneoplastic lesions detected by immunostaining with an anti-KRT8/18 antibody were observed in PB-treated but not PCN-treated mice, and PCN cotreatment augmented the formation of preneoplastic lesions by PB. After 35 weeks of treatment, macroscopic observations indicated that PB-treated and PB/PCN-cotreated mice had increased numbers of liver tumors compared to control and PCN-treated mice. In the pathological analyses of liver sections, all the mice in the PB and PB/PCN groups developed carcinoma and/or eosinophilic adenoma, but in the PB/PCN group, the multiplicity of carcinoma and eosinophilic adenoma was significantly reduced and the size of carcinoma showed a tendency to decrease. No mouse in the control or PCN-treated group developed such tumors. Differentially expressed gene (DEG) and gene set enrichment analyses in combination with RNA sequencing suggested the increased expression of genes related to epithelial-mesenchymal transition (EMT) in mice cotreated with PCN and PB compared to those treated with PB alone. Changes in the hepatic mRNA levels of epithelial marker genes supported the results of the transcriptome analyses. In conclusion, the present results suggest that PXR activation does not promote hepatocarcinogenesis in contrast to CAR and rather attenuates CAR-mediated liver cancer development by suppressing the EMT of liver cancer cells in rodents.

Real-world efficacy and safety of 12-week sofosbuvir/velpatasvir treatment for patients with decompensated liver cirrhosis caused by hepatitis C virus infection

AIM

This study aimed to evaluate the real-world efficacy and safety of 12-week sofosbuvir/velpatasvir (SOF/VEL) treatment for patients with decompensated liver cirrhosis caused by hepatitis C virus (HCV) infection.

METHODS

A total 72 of patients with Child-Pugh (CP) class B or C were enrolled. We evaluated the sustained virologic response at 12 weeks after the end of treatment (SVR12), adverse events (AEs), and changes in the liver function.

RESULTS

All participants had genotype 1 or 2 HCV infection. At baseline, the numbers of patients with CP class B and C were 59 and 13, respectively. The overall SVR12 rate was 95.8% (69/72); 94.9% (56/59) in CP class B and 100% (13/13) in CP class C. The serum albumin level, prothrombin time and ascites were significantly improved (P < 0.01); however, the serum bilirubin level and encephalopathy did not improve. Among patients who achieved SVR12, 75.0% showed an improvement in their CP score, while 5.9% showed a worsening. The presence of large portosystemic shunt (diameter ≥6 mm) and hyperbilirubinemia (≥2.0 mg/dL) were independent factors that interfered with the improvement in the CP score (P < 0.05). The most common AEs were encephalopathy (15.3%) and skin symptoms (7.9%). Two patients discontinued SOF/VEL due to AEs.

CONCLUSIONS

Treatment with SOF/VEL for 12 weeks was relatively safe and effective for patients with decompensated cirrhosis. An SVR provided an improvement of the liver function in the majority of patients. However, large portosystemic shunt and hyperbilirubinemia were independent factors that interfered with the improvement in the CP score.

Follow-up after Direct-acting Antiviral Treatment for Chronic Hepatitis C Virus Infection: Most Patients Are Followed Appropriately

Objective Chronic hepatitis C virus (HCV) infection carries a residual risk of hepatocarcinogenesis even after viral elimination, so appropriate follow-up is necessary. The present study investigated the current hospital visits and hepatocarcinogenesis status of patients who received daclatasvir plus asunaprevir treatment (DCV+ASV) to determine whether or not appropriate follow-up was being performed. Methods We retrospectively analyzed hepatocarcinogenesis, the overall survival, and the length of hospital visits in 442 patients who applied for the medical expense subsidy system for viral hepatitis and received DCV+ASV treatment in Gunma Prefecture between October 2014 and December 2015. This also included 61 patients who had a history of hepatocellular carcinoma (HCC). Results Among 442 patients, 388 achieved a sustained viral response (SVR) by DCV+ASV therapy (87.8%), and 95.9% achieved an SVR if additional treatment was included. HCC was found in 75 cases (17.0%). A history of HCC, the FIB-4 index and the treatment effect SVR were determined to be factors affecting the incidence of HCC. Regarding the follow-up rate, 89.9% of patients continued to regularly visit the hospital after 5 years of treatment. However, patients ≤60 years old had significantly lower persistence rates than older patients. The persistence rate of hospital visits to the same institution was 67.7% over a 5-year period, which was significantly better in small and medium-sized institutions than in large, specialized institutions (71.7% vs. 63.9%, p=0.039). Conclusion Patients with direct-acting antiviral treatment generally received adequate follow-up, but younger patients had a slightly higher rate of follow-up interruption and were considered to need support.

The Role of the Albumin-Bilirubin Score for Predicting the Outcomes in Japanese Patients with Advanced Hepatocellular Carcinoma Treated with Ramucirumab: A Real-World Study

AIM

The aim of this retrospective study was to investigate the efficacy and safety of ramucirumab treatment under real-world conditions and to clarify the role of albumin-bilirubin (ALBI) score in predicting outcomes.

METHODS

Between June 2019 and May 2020, a total of 16 patients with advanced hepatocellular carcinoma (HCC) treated with ramucirumab in Gunma Saiseikai Maebashi Hospital and its affiliated hospitals was included.

RESULTS

The median age was 71 (interquartile range [IQR] 65-74) years old, and 12 patients (75.0%) were male. The modified ALBI (mALBI) grade was 1, 2a, and 2b at baseline in 4 (25.0%), 3 (18.8%), and 9 patients (56.3%), respectively. The Barcelona Clinic Liver Cancer stage was intermediate and advanced stage in 1 (6.3%) and 15 patients (93.8%), respectively. The serum α-fetoprotein at baseline was 4,911 (IQR 2,091-17,377) ng/mL. The disease control rate in patients with mALBI grade1 + 2a was significantly higher than in those with mALBI grade 2b (100 vs. 28.6%, p = 0.028). The patients with mALBI grade 1 + 2a had a significantly better overall survival (OS) and longer progression-free survival (PFS) than those with mALBI grade 2b (median OS 6.7 vs. 3.0 months; p = 0.036, median PFS 7.5 vs. 1.4 months; p = 0.002). The number of cycles of ramucirumab treatment was significantly correlated with the ALBI score (r = -0.452, p = 0.030). The patients with mALBI grade 1 + 2a showed a low incidence of adverse events (AEs) and discontinuation due to AEs.

CONCLUSIONS

Advanced HCC patients with mALBI grade 1 + 2a may be a good indication for ramucirumab treatment.
