RESUMO
BACKGROUND: Immuno-oncology (IO) drugs are essential for treating various cancer types; however, safety concerns persist in older patients. Although the incidence of immune-related adverse events (irAEs) is similar among age groups, higher rates of hospitalization or discontinuation of IO therapy have been reported in older patients. Limited research exists on IO drug safety and risk factors in older adults. Our investigation aimed to assess the incidence of irAEs and identify the potential risk factors associated with their development. METHODS: This retrospective analysis reviewed the clinical data extracted from the medical records of patients aged > 80 years who underwent IO treatment at our institution. Univariate and multivariate analyses were performed to assess the incidence of irAEs. RESULTS: Our study included 181 patients (median age: 82 years, range: 80-94), mostly men (73%), with a performance status of 0-1 in 87% of the cases; 64% received IO monotherapy. irAEs occurred in 35% of patients, contributing to IO therapy discontinuation in 19%. Our analysis highlighted increased body mass index, eosinophil counts, and albumin levels in patients with irAEs. Eosinophil count emerged as a significant risk factor for any grade irAEs, particularly Grade 3 or higher, with a cutoff of 118 (/µL). The group with eosinophil counts > 118 had a higher frequency of irAEs, and Grade 3 or higher events than the group with counts ≤ 118. CONCLUSION: IO therapy is a safe treatment option for patients > 80 years old. Furthermore, patients with elevated eosinophil counts at treatment initiation should be cautiously managed.

BACKGROUND & AIMS: The study goal was to compare the outcomes of patients with intermediate-stage (Barcelona Clinic Liver Cancer [BCLC]-B) hepatocellular carcinoma (HCC) who received atezolizumab plus bevacizumab (Atezo/Bev) or lenvatinib (LEN) as first-line systemic therapy. METHODS: A total of 358 patients with BCLC-B HCC treated with Atezo/Bev (n = 177) or LEN (n = 181) as first-line systemic therapy were included. RESULTS: The median progression-free survival (PFS) times in the Atezo/Bev and LEN groups were 10.8 months (95% confidence interval [CI], 7.8-12.6) and 7.3 months (95% CI, 6.3-8.5), respectively (p = .019). In the propensity score-matched cohort, the median PFS times in the Atezo/Bev (n = 151) and LEN (n = 151) groups were 10.2 months (95% CI, 7.0-12.3) and 6.9 months (95% CI, 5.9-8.1), respectively (p = .020). Restricted mean survival times of PFS were significantly higher in the Atezo/Bev group than in the LEN group at landmarks of 12 and 18 months (p = .031 and .012, respectively). In a subgroup analysis of patients with HCC beyond the up-to-seven criteria, the median PFS times in the Atezo/Bev (n = 134) and LEN (n = 117) groups were 10.5 months (95% CI, 7.0-11.8) and 6.3 months (95% CI, 5.5-7.3), respectively (p = .044). CONCLUSIONS: The use of Atezo/Bev as first-line systemic therapy in patients with BCLC-B HCC is expected to result in good PFS.

AIM: Elderly patients are believed to have a reduced immune capacity, which may make immunotherapy less effective. The aim of this study was to compare the therapeutic outcome of atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib (LEN) for advanced hepatocellular carcinoma (HCC) in patients aged 80 years and older. METHODS: From March 2018 to July 2022, 170 and 92 elderly patients who received LEN and Atez/Bev as first-line treatment, respectively, were retrospectively analyzed. RESULTS: The median ages of the Atez/Bev and LEN groups were 83.0 (8.01-86.0) and 83.0 (82.0-86.0) years (p = 0.3), respectively. Men accounted for approximately 70% of the patients in both groups. The objective response rate was 35.9% in the LEN group and 33.7% in the Atez/Bev group (p = 0.8), whereas the disease control rates in the LEN and Atez/Bev groups were 62.9% and 63.0%, respectively (p = 1.0). The median progression-free survival (PFS) in the LEN and Atez/Bev groups was 6.3 and 7.2 months, respectively, which were not significantly different (p = 0.2). The median overall survival (OS) was 17.9 months in the LEN group and 14.0 months in the Atez/Bev group. This difference was not statistically significant (p = 0.7). In multivariate analyses, the choice of treatment (LEN vs. Atez/Bev) showed no association with PFS or OS. The Atez/Bev group had a significantly higher rate of postprogression treatment (59.0% vs. 35.7%, p = 0.01) and a lower rate of discontinuation due to adverse events (69 [40.6%] vs. 19 [20.7%], p < 0.001) compared to the LEN group. CONCLUSIONS: Atezolizumab plus bevacizumab showed comparable effectiveness to LEN in HCC patients aged 80 years and older. Given the results of postprogression treatment and discontinuation due to adverse events, Atez/Bev could serve as a first-line treatment even for elderly HCC patients.
RESUMO
BACKGROUND: Liver resection offers substantial advantages over open liver resection (OLR) for patients with hepatocellular carcinoma (HCC) in terms of reduced intraoperative blood loss and morbidity. However, there is limited evidence comparing the indications and perioperative outcomes with the open versus laparoscopic approach for resection. This study aimed to compare postoperative outcomes between patients undergoing laparoscopic liver resection (LLR) and OLR for HCC with clinically significant portal hypertension (CSPH). METHODS: A total of 316 HCC patients with CSPH (the presence of gastroesophageal varices or platelet count < 100,000/ml and spleen diameter > 12 cm) undergoing minor liver resection at eight centers were included in this study. To adjust for confounding factors between the LLR and OLR groups, an inverse probability weighting method analysis was performed. RESULTS: Overall, 193 patients underwent LLR and 123 underwent OLR. After weighting, LLR was associated with a lower volume of intraoperative blood loss and the incidence of postoperative complications (including pulmonary complications, incisional surgical site infection, and paralytic ileus) compared to the OLR group. The 3-, 5-, and 7-year postoperative recurrence-free survival rates were 39%, 26%, and 22% in the LLR group and 49%, 18%, and 18% in the OLR group, respectively (p = 0.18). And, the 3-, 5-, and 7-year postoperative overall survival rates were 71%, 56%, and 44% in the LLR group and 76%, 51%, 44% in the OLR group, respectively (p = 0.87). CONCLUSIONS: LLR for HCC patients with CSPH is clinically advantageous by lowering the volume of intraoperative blood loss and incidence of postoperative complications, thereby offering feasible long-term survival.

PURPOSE AND BACKGROUND: For the past decade, there have been few chemotherapy options for unresectable biliary tract cancer (BTC). Recently, however, combination therapy with gemcitabine and cisplatin plus S-1 (GCS) has been identified as a promising strategy. This retrospective study analyzes the clinical results of GCS therapy and subsequent conversion surgery (CS). METHOD: We analyzed the clinical data of 60 consecutive patients who received GCS therapy for unresectable upper BTC at our university hospital during the 5 years between September, 2018 and December, 2022. RESULTS: All patients received GCS therapy as first-line chemotherapy. The response rate was 33.9% and subsequent CS was performed in 35.0%. Of the patients who underwent CS, 81% required more than bisectionectomy of the liver with extrahepatic bile duct resection. The median overall survival of the patients who received GCS therapy and underwent subsequent CS was significantly longer than that of the patients who received GCS therapy alone (28.0 months vs. 12.4 months, respectively; p < 0.001). A decrease in the CA19-9 level 1 month after chemotherapy and RECIST PR were independent positive predictors of CS, whereas unresectable gallbladder cancer and pretreatment ALBI grade 3 were negative predictors of CS. CONCLUSION: GCS therapy and subsequent CS may contribute to the longer term survival of patients with unresectable upper BTC.
RESUMO
BACKGROUND: Complex hepatocellular carcinoma (HCC) prognostic biomarkers have been reported in various studies. We aimed to establish biomarkers that could predict prognosis, and formulate a simple classification using non-invasive preoperative blood test data. METHODS: We retrospectively identified 305 patients for a discovery cohort who had undergone HCC-related hepatectomy at four Japanese university hospitals between January 1, 2011 and December 31, 2013. Preoperative blood test parameter optimal cut-off values were determined using receiver operating characteristic curve analysis. Cox uni- and multivariate analyses were used to determine independent prognostic factors. Risk classifications were established using classification and regression tree (CART) analysis. Validation was performed with 267 patients from three other hospitals. RESULTS: In multivariate analysis, α-fetoprotein (AFP, p < 0.001), protein induced by vitamin K absence or antagonist-II (PIVKA-II, p = 0.006), and C-reactive protein (CRP, p < 0.001) were independent prognostic factors for overall survival (OS). AFP (p = 0.007), total bilirubin (p = 0.001), and CRP (p = 0.003) were independent recurrent risk factors for recurrence-free survival (RFS). CART analysis results formed OS (CRP, AFP, and albumin) and RFS (PIVKA-II, CRP, and total bilirubin) decision trees, based on machine learning using preoperative serum markers, with three risk classifications. Five-year OS (low risk, 80.0%; moderate risk, 56.3%; high risk, 25.2%; p < 0.001) and RFS (low risk, 43.4%; moderate risk, 30.8%; high risk, 16.6%; p < 0.001) risks differed significantly. These classifications also stratified OS and RFS risk in the validation cohort. CONCLUSION: Three simple risk classifications using preoperative non-invasive prognostic factors could predict prognosis.

INTRODUCTION: Atezolizumab plus bevacizumab (ATZ+BV) treatment has become the first-line regimen for unresectable hepatocellular carcinoma (u-HCC). Prediction of response to it might be clinically beneficial. Using peripheral blood parameters, we aimed to construct a prediction model for ATZ+BV treatment. METHODS: Clinical records of 119 patients with u-HCC treated by ATZ+BV were retrospectively analyzed. The primary outcome measurement was defined as any-size reduction at the initial image evaluation. Using baseline values of peripheral blood parameters, a prediction model was constructed by univariate and multivariate logistic regression analysis. Validation was performed internally by bootstrap method. RESULTS: The primary outcome was achieved in 46 patients. Univariate analysis showed that C-reactive protein (CRP), alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were possible predictors. CRP and DCP, and NLR and PLR had correlation (correlation coefficient >0.3), so we used CRP and NLR as representative factors, respectively. Multivariate analysis constructed the following prediction model: Logit = 1.62-0.61×[CRP] -0.38×[Log10AFP] -0.37×[NLR]. Bootstrapped median (95% confidence interval) of coefficients of CRP, Log10AFP, NLR were -0.64 (-1.46 â¼ -0.11), -0.40 (-0.82 â¼ -0.03), and -0.38 (-0.74 â¼ -0.05), respectively. The area under the receiver operating characteristic curve (95% confidence interval) was 0.73 (0.60-0.80). Median overall survival of the favorably and unfavorably predicted groups were 17.0 and 11.0 months (p = 0.03), respectively. DISCUSSION: In patients with u-HCC treated by ATZ+BEV, a prediction model constructed using baseline values of CRP, AFP, and NLR had impact on any-size reduction at the initial image evaluation and on prognosis.

INTRODUCTION: This study investigated the relationship between nutritional status, as determined by the prognostic nutritional index (PNI), and outcomes in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atez/bev). METHODS: The study analyzed 485 HCC patients treated with Atez/bev. RESULTS: There were 342 patients with a low PNI (<47) and 143 patients with a high PNI (≥47). The median follow-up duration was 9.4 (6.0-14.3) months. Multivariate Cox hazards analysis showed that an α-fetoprotein level ≥100 ng/mL (hazard ratio (HR), 2.217; 95% confidence interval (CI), 1.588-3.095; p < 0.001), and PNI ≥47 (HR, 0.333; 95% CI, 0.212-0.525; p < 0.001) were independently associated with overall survival. Multivariate analysis showed that an α-fetoprotein level ≥100 ng/mL (HR, 1.690; 95% CI, 1.316-2.170; p < 0.001) and PNI ≥47 (HR, 0.696; 95% CI, 0.528-0.918; p = 0.010) were independently associated with progression-free survival. Cumulative overall and progression-free survival rates differed significantly by PNI (p < 0.001 and p < 0.002, respectively). In a subgroup analysis using inverse probability weighting adjustment in patients with albumin-bilirubin grade 1 (n = 173), univariate Cox hazards analysis showed that a PNI ≥47 (HR, 0.502; 95% CI, 0.260-0.991; p = 0.047) was significantly associated with overall survival. Spline curve analysis revealed that a PNI of approximately 34-48 is an appropriate cutoff for predicting good overall and progression-free survival. CONCLUSION: The PNI, a biomarker of nutritional status, can predict prognosis in patients with HCC treated with Atez/bev, even those who are considered to have a good prognosis due to good liver function.

INTRODUCTION: Systemic treatment is generally recommended for Child-Pugh (CP) A status patients with an unresectable hepatocellular carcinoma (uHCC). This study aimed to elucidate differences regarding therapeutic efficacy between lenvatinib (LEN), a multi-molecular target agent, and atezolizumab plus bevacizumab (Atez/Bev), a newly developed immune-combined therapeutic regimen for CP-B patients affected by uHCC. METHODS: From April 2018 to July 2022, 128 patients with uHCC treated with Atez/Bev (n = 29) or LEN (n = 99) as the initial systemic treatment were enrolled (median age 71 years; males 97; CP score 7:8:9 = 94:28:6; median albumin-bilirubin score -1.71). Therapeutic response was evaluated using RECIST, version 1.1. Clinical features and prognosis were retrospectively examined. RESULTS: There were no significant differences between the Atez/Bev and LEN groups in regard to best response (CR:PR:SD:PD = 0:5:12:7 vs. 5:22:25:20, p = 0.415), progression-free survival (PFS) (median 5.0 [95% CI: 2.4-7] vs. 5.5 [95% CI: 3.4-7.9] months, p = 0.332), or overall survival (OS) (5.8 [95% CI: 4.3-11] vs. 8.8 [95% CI: 6.1-12.9] months, p = 0.178). Adverse events (any grade/≥ grade 3) were observed in 72.4%/17.2% (n = 21/5) of patients treated with Atez/Bev and 78.8%/25.3% (n = 78/25) of those treated with LEN (p = 0.46/0.46). DISCUSSION: This retrospective study found no significant differences regarding PFS or OS between CP-B patients given Atez/Bev or LEN as initial systemic treatment for uHCC.

INTRODUCTION: Lack of an established methodology for post-progression systemic treatment following atezolizumab plus bevacizumab (Atez/Bev) administration is an important clinical issue. The present study aimed to elucidate the potential of lenvatinib as a second-line treatment option after Atez/Bev failure. METHODS: From 2020 to 2022, 101 patients who received lenvatinib as second-line treatment were enrolled (median 72 years, males 77, Child-Pugh A 82, BCLC-A:B:C:D = 1:35:61:4), while 29 treated with another molecular targeting agent (MTA) during the period as second-line treatment were enrolled as controls. The therapeutic efficacy of lenvatinib given as second-line treatment was retrospectively evaluated. RESULTS: Median progression-free survival/median overall survival for all patients was 4.4/15.7 months and for those with Child-Pugh A was 4.7 months/not-reached. When prognosis was compared with patients who received another MTA, there was no significant difference for PFS (3.5 months, p = 0.557) or OS (13.6 months, p = 0.992), and also no significant differences regarding clinical background factors. mRECIST findings showed that objective response and disease control rates in patients treated with lenvatinib were 23.9% and 70.4%, respectively (CR:PR:SD:PD = 3:14:33:21), while those shown by RECIST, ver. 1.1, were 15.4% and 66.2%, respectively (CR:PR:SD:PD = 1:10:36:24). Adverse events (any grade ≥10%) were appetite loss (26.7%) (grade 1:2:3 = 2:15:10), general fatigue (21.8%) (grade 1:2:3 = 3:13:6), protein in urine (16.8%) (grade 1:2:3 = 0:4:13), and hypertension (13.9%) (grade 1:2:3 = 1:8:5). CONCLUSION: Although lenvatinib treatment might not provide a pseudo-combination immunotherapy effect following Atez/Bev failure, lenvatinib when used as second-line treatment after Atez/Bev failure might be expected to be comparable as compared to its use as first-line treatment.

AIM: Coronavirus disease 2019 emerged in December 2019 and spread worldwide. This study aimed to clarify the impact of the coronavirus disease 2019 pandemic on the diagnosis and treatment of hepatocellular carcinoma (HCC) in Japan. METHODS: First, we collected the monthly numbers of HCC-related general medical practices from January 2019 to December 2021 at liver disease-specific medical institutions in Japan. Next, we collected individual clinical information from patients with newly diagnosed HCC during this period. RESULTS: There was a decrease in the number of HCC-related medical practices, including referrals, enhanced abdominal ultrasonography and radiofrequency ablation, in Japan's first state of emergency (SOE; April-May 2020) compared with 2019. Fewer patients were diagnosed with new HCC during the first SOE than before or after it. There was no difference in tumor diameter, number of tumors or Barcelona Clinic Liver Cancer stage between patients diagnosed before the first SOE and those diagnosed during or after the first SOE. The median waiting times for treatment of patients diagnosed during and after the first SOE were 31 and 37 days, which were significantly shorter and not longer than that of patients diagnosed before the first SOE (36 days), respectively. CONCLUSION: The number of HCC-related general medical practices decreased during the first SOE. However, the coronavirus disease 2019 pandemic did not lead to HCC progression by diagnostic delays or cause HCC treatment delays in Japan.
RESUMO
The fifth version of the Clinical Practice Guidelines for Hepatocellular Carcinoma was revised by the Japan Society of Hepatology, according to the methodology of evidence-based medicine and partly to the Grading of Recommendations Assessment, Development and Evaluation system, which was published in October 2021 in Japanese. In addition to surveillance-diagnostic and treatment algorithms, a new algorithm for systemic therapy has been created, as multiple drugs for hepatocellular carcinoma can be currently selected. Here, new or revised algorithms and evidence on which the recommendations are based are described.
RESUMO
AIM: The present study focused on Geriatric Nutritional Risk Index (GNRI), which is based on bodyweight and serum albumin, and known as an easy-to-use nutritional assessment tool in clinical settings, to elucidate the prognostic predictive ability of GNRI in patients treated with atezolizumab plus bevacizumab (Atez/Bev) for hepatocellular carcinoma (HCC). METHODS: A total of 525 HCC patients treated with Atez/Bev, based on their classification of unsuitable status for curative treatments and/or transarterial catheter chemoembolization, were enrolled (Child-Pugh A:B:C = 484:40:1, Barcelona Clinic Liver Cancer stage 0:A:B:C:D = 7:25:192:283:18). Prognosis was evaluated retrospectively using GNRI. RESULTS: Atez/Bev was used in 338 of the present cohort as first-line systemic chemotherapy (64.4%). Median progression-free survival based on GNRI indicating normal, mild decline, moderate decline, and severe decline was 8.3, 6.7, 5.3, and 2.4 months, respectively, whereas median overall survival was 21.4, 17.0, 11.5. and 7.3 months, respectively (both p < 0.001). The concordance index (c-index) values of GNRI for predicting prognosis (progression-free survival/overall survival) were superior to those of Child-Pugh class and albumin-bilirubin grade (0.574/0.632 vs. 0.527/0.570 vs. 0.565/0.629). As a subanalysis, muscle volume loss was observed in 37.5% of 256 patients with computed tomography data available. Along with GNRI decline, frequency of muscle volume loss became progressively larger (normal vs. mild vs. moderate vs. severe = 17.6% vs. 29.2% vs. 41.2% vs. 57.9%, p < 0.001), and a GNRI value of 97.8 was predictive of its occurrence (AUC 0.715, 95% CI 0.649-0.781; specificity/sensitivity = 0.644/0.688). CONCLUSION: These findings indicate that GNRI is an effective nutritional prognostic tool for predicting prognosis and muscle volume loss complication in HCC patients treated with Atez/Bev.
RESUMO
AIM: This retrospective study aimed to investigate the impact of proton pump inhibitor treatment (PPI) and antibiotic treatment on the therapeutic outcomes of hepatocellular carcinoma (HCC) patients receiving atezolizumab and bevacizumab (Atez/Bev). METHODS: The present study included a total of 441 HCC patients who were treated with Atez/Bev in 20 Japanese institutions from September 2020 to April 2022. We adopted the inverse probability of treatment weight to adjust for imbalance in the baseline characteristics of patients with and without PPI treatment as well as patients with and without antibiotic treatment. RESULTS: The progression-free survival (PFS) and overall survival (OS) of patients with and without PPI treatment did not differ to a statistically significant extent. In the weighted cohort, the difference in PFS and OS between the patients with and without PPI did not reach statistical significance (median PFS, 7.0 vs. 6.5 months, p = 0.07; 1-year survival rate 66.3% and 73.8%, p = 0.9). The PFS and OS in patients with antibiotic treatment were worse in comparison to patients without antibiotic treatment (median PFS, 3.8 vs. 7.0 months, p = 0.007; 1-year survival rate 58.8% and 70.3%, p = 0.01). In the weighted cohort, the PFS and OS of the two groups did not differ to a statistically significant extent (median PFS, 3.8 vs. 6.7 months, p = 0.2; 1-year survival rate, 61.8% and 71.0%, p = 0.6). CONCLUSIONS: The therapeutic outcomes of Atez/Bev in HCC patients did not differ between patients with and without PPI treatment or between patients with and without antibiotic treatment.
RESUMO
BACKGROUND AND AIM: The study goal was to compare the outcomes of patients with unresectable hepatocellular carcinoma (HCC) who received atezolizumab plus bevacizumab (Atezo/Bev) as either first- or later-line systemic therapy. METHODS: A total of 430 patients with HCC treated with Atezo/Bev at 22 institutions in Japan were included. Patients treated with Atezo/Bev as first-line therapy for HCC were defined as the first-line group (n = 268) while those treated with Atezo/Bev as second- or later-line therapy were defined as the later-line group (n = 162). RESULTS: The median progression-free survival times in the first- and later-line groups were 7.7 months (95% confidence interval [CI], 6.7-9.2) and 6.2 months (95% CI, 5.0-7.7) (P = 0.021). Regarding treatment-related adverse events, hypertension of any grade was more common in the first-line group than in the later-line group (P = 0.025). Analysis adjusted by inverse probability weighting, including patient and HCC characteristics, showed that the later-line group (hazard ratio, 1.304; 95% CI, 1.006-1.690; P = 0.045) was significantly associated with progression-free survival. In patients with Barcelona Clinic Liver Cancer stage B, the median progression-free survival times in the first- and later-line groups were 10.5 months (95% CI, 6.8-13.8) and 6.8 months (95% CI, 5.0-9.4) (P = 0.021). Among patients with a history of lenvatinib therapy, the median progression-free survival times in the first- and later-line groups were 7.7 months (95% CI, 6.3-9.2) and 6.2 months (95% CI, 5.0-7.7) (P = 0.022). CONCLUSION: The use of Atezo/Bev as first-line systemic therapy in patients with HCC is expected to prolong survival.

PURPOSE: Candida spp. cause opportunistic infections in conditions of immunodeficiency. Here, we investigated the relationship between colonization of the gastric juice by Candida spp. and surgical site infection (SSI) in hepatectomy. METHODS: Consecutive hepatectomy cases between November 2019 and April 2021 were enrolled. Gastric juice samples (collected intraoperatively through a nasogastric tube) were cultured. We compared factors related to patient background, blood test findings, surgical findings, and postoperative complications between the Candida + group (positive for colonization of the gastric juice by Candida spp.) and the Candida - group (negative). In addition, we identified the factors that contribute to SSI. RESULTS: There were 29 and 71 patients in the Candida + and Candida - groups, respectively. The Candida + group was significantly older (average age: Candida + 74 years vs. Candida - 69 years; p = 0.02) and contained more patients negative for the hepatitis B and C virus (Candida + 93% vs. Candida - 69%; p = 0.02). SSI was significantly more common in the Candida + group (Candida + 31% vs. Candida - 9%; p = 0.01). Postoperative bile leakage and colonization of the gastric juice by Candida spp. were independent predictors of SSI. CONCLUSION: Colonization of the gastric juice by Candida spp. is a risk factor for SSI after hepatectomy.

The aim of the current study was to investigate the efficacy and safety of sorafenib and intermittent hepatic arterial infusion chemotherapy with cisplatin for unresectable hepatocellular carcinoma (HCC) with severe portal vein invasion. The antitumor effect was a complete response in 1 of 38 patients, a partial response in 12 patients, stable disease in 16 patients, and progressive disease in 9 patients, for a 34.2% response rate and a 76.3% disease control rate. This regimen had favorable efficacy and acceptable safety and may be feasible for unresectable HCC with severe portal vein invasion.

INTRODUCTION: Adverse events (AEs) of urinary protein from monoclonal antibodies against vascular endothelial growth factor are factors that often inhibit systemic therapy for unresectable hepatocellular carcinoma (uHCC). This study aimed to elucidate risk factors of urinary protein in the early period (<12 weeks) of atezolizumab plus bevacizumab treatment (Atez/Bev). METHODS: From 2020 to June 2022, 193 uHCC patients treated with Atez/Bev at our affiliated hospitals were enrolled (median 73 years, 158 males, 183 Child-Pugh A, BCLC-0:A:B:C = 1:7:73:112). AEs related to urinary protein (≥G2) within 12 weeks were defined as significant, and related clinical features were analyzed retrospectively. RESULTS: In analyses of risk factors of urinary protein-related AEs during the first 12 weeks after starting Atez/Bev using a logistic regression method, univariate analysis showed positive for hypertension (odds ratio [OR] 3.54, 95% CI: 1.28-9.80, p = 0.015) and baseline urinary protein and urine creatinine ratio (UPC: ≥0.16) (OR: 2.52, 95% CI: 1.09-5.83, p = 0.031) as pretreatment clinical factors, while elevation of urinary protein in the early period (baseline to 3 weeks) with delta UPC per 3 weeks (ΔUPC/3W) (≥0.23) (OR: 15.80, 95% CI: 6.15-40.50, p < 0.001) was a clinical factor after starting treatment. Multivariate analysis of only baseline clinical factors revealed positive for history of hypertension as the only predictive factor (OR: 3.20, 95% CI: 1.14-8.95, p = 0.027), while only ΔUPC/3W (≥0.23) (OR: 14.40, 95% CI: 4.91-42.00, p < 0.001) were noted in multivariate analysis including ΔUPC/3W. Predictive factors for ΔUPC/3W (≥0.23) were hypertension (OR: 3.50, 95% CI: 1.23-99.90, p = 0.019) and UPC (≥0.16) (OR: 6.12, 95% CI: 2.61-14.30, p < 0.001) in multiple analysis. DISCUSSION/CONCLUSION: Urinary protein-related AEs are frequently observed during Atez/Bev treatment in uHCC patients with elevated ΔUPC/3W (≥0.23), and ΔUPC/3W (≥0.23) is often seen in patients with hypertension and/or UPC (≥0.16).

Roxadustat and other hypoxia-inducible factor-prolyl hydroxylase inhibitors (HIF-PHIs) have recently been approved for the treatment of chronic renal anemia. In macrophages and monocytes, the activation of HIF-1 by pro-inflammatory cytokines induces iNOS expression and activity through the NF-κB pathway to produce nitric oxide (NO), which causes liver injury when excessively produced. Few studies have reported a relationship between HIF activity and iNOS induction in hepatocytes. We investigated the effect of drug- and hypoxia-induced HIF activations on NO production in primary cultured rat hepatocytes. Roxadustat treatment and hypoxic conditions activated HIF. Contrary to expectations, HIF-PHI treatment and hypoxia inhibited IL-1ß-induced NO production. RNA-Seq analysis of mRNA expression in rat hepatocytes showed that roxadustat treatment decreased the expression of genes related to inflammation, and genes in the NF-κB signaling pathway were induced by IL-1ß. Moreover, roxadustat suppressed IL-1ß-activated signaling pathways in an HIF-dependent manner. GalN/LPS-treated rats were used as in vivo models of hepatic injury, and roxadustat treatment showed a tendency to suppress the death of rats. Therefore, exogenous HIF-1 activation, including HIF-PHI and hypoxia exposures, suppressed IL-1ß-induced iNOS mRNA expression and subsequent NO production in hepatocytes, by suppressing the NF-κB signaling pathway. Roxadustat treatment suppresses the expression of pro-inflammatory genes by activating HIF, and thus may exhibit hepatoprotective effects.

BACKGROUND: Postoperative adhesions are a potentially life-threatening complication of abdominal surgery. We previously showed that substance P (SP), acting through the neurokinin-1 receptor (NK-1R), is an important early mediator of adhesiogenesis through its regulation of the tissue plasminogen activator/plasminogen activator inhibitor-1 (PAI-1) fibrinolytic system. SP also mediates neurogenic inflammation by recruiting inflammatory leukocytes, such as neutrophils and macrophages. Our objective was to determine the role of SP-dependent chemotactic recruitment of these inflammatory cells through the CXCR2 in postsurgical adhesion formation. MATERIALS AND METHODS: A mouse cecal cauterization model was used to generate intra-abdominal adhesions. Protein and mRNA levels of the chemokines CXCL1 and CXCL2 and their receptor CXCR2 were measured at 3 h and 6 h after surgery in peritoneal tissue and in peritoneal lavages in response to antagonists for the SP receptor and CXCR2, and in IFN-γ knockout mice. RESULTS: Postsurgical adhesion formation was inhibited by both an antagonist to NK-1R and an antagonist to CXCR2. Expression levels of neutrophil chemokines and CXCR2 in peritoneal tissue peaked 3-6 h after surgery and partially depended on SP and IFN-γ, one of its downstream mediators. An NK-1R antagonist inhibited SP-mediated increases in the expression of the PAI-1 inhibitory component of the fibrinolytic system, but the CXCR2 antagonist had no effect. CONCLUSIONS: Postsurgical adhesiogenesis involves upregulation of chemokine signaling that is partially SP- and IFN-γ-dependent. However, the adhesiogenic properties of chemokine signaling are not mediated through the inhibition of fibrinolysis with PAI-1, as was previously shown for SP.
