[PMID: 37705533 PMCID: PMC10495918 DOI: 10.1177/17588359221148541] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 12/14/2022] [Indexed: 09/15/2023] Open
Abstract
Background Atezolizumab plus bevacizumab (Ate/Bev) demonstrated promising efficacy and safety in patients with advanced hepatocellular carcinoma (HCC) in the phase III IMbrave150 trial. However, patients with Child-Pugh B HCC were excluded in the abovementioned prospective trial. Therefore, we aimed to investigate the efficacy and safety of Ate/Bev in patients with Child-Pugh B HCC. Methods This multicenter retrospective study included 36 patients with Child-Pugh B advanced HCC who received Ate/Bev at four cancer referral centers between May 2020 and August 2021. Comparative analyses were performed with an independent cohort of patients with Child-Pugh A HCC from the same registry (n = 133). Results All patients received Ate/Bev as first-line systemic treatment for advanced HCC. The objective response and disease control rates of patients in the Child-Pugh groups B and A were 11.1% and 58.3% and 34.6% and 76.7%, respectively. The median progression-free survival (PFS) and overall survival (OS) were 3.0 months [95% confidence interval (CI), 1.7-4.3) and 7.7 months (95% CI, 4.8-10.6) in the Child-Pugh B group, whereas the median PFS and OS were 9.6 months (95% CI, 5.1-14.2) and not reached (95% CI, not available) in the Child-Pugh A group, respectively. Compared to the Child-Pugh A group, grade 3-4 adverse events (AEs) were more common in the Child-Pugh B group (44.4% versus 15.8, p < 0.001), with the most frequent grade 3-4 AEs being gastrointestinal bleeding (n = 6, 16.7%), neutropenia (n = 5, 13.9%), and thrombocytopenia (n = 4, 11.1%). Conclusions In the Child-Pugh B subgroup of patients with advanced HCC, Ate/Bev treatment showed modest clinical activity. However, due to the increased frequency of serious AEs, careful evaluation of treatment response and AE management is required in this subgroup of patients.

Trastuzumab plus FOLFOX for HER2-positive biliary tract cancer refractory to gemcitabine and cisplatin: a multi-institutional phase 2 trial of the Korean Cancer Study Group (KCSG-HB19-14). Lancet Gastroenterol Hepatol 2023; 8:56-65. [PMID: 36328033 DOI: 10.1016/s2468-1253(22)00335-1] [Citation(s) in RCA: 24] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 09/26/2022] [Accepted: 09/26/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND HER2 overexpression or amplification, which is present in 15% of all cases of biliary tract cancer, has been identified as a druggable molecular target by genomic profiling. In the phase 3 ABC-06 trial, the folinic acid, fluorouracil, and oxaliplatin (FOLFOX) regimen showed a survival benefit compared with active symptom control as second-line therapy for biliary tract cancer. We aimed to evaluate the clinical activity of FOLFOX plus anti-HER2 antibody trastuzumab as a second-line or third-line treatment for HER2-positive biliary tract cancer. METHODS This study was an investigator-initiated, open-label, non-randomised, single-arm, multi institutional, phase 2 trial in participants aged 19 years or older with HER2-positive (defined as immunohistochemistry 3+ or immunohistochemistry 2+ and in-situ hybridisation positive or ERBB2 gene copy number ≥6·0 by next-generation sequencing) biliary tract cancer (intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder cancer) who progressed on chemotherapy containing gemcitabine and cisplatin (with one or two previous chemotherapy lines permitted). In cycle one, patients received intravenous trastuzumab-pkrb at 6 mg/kg on day 1, and FOLFOX (consisting of intravenous oxaliplatin [85 mg/m2], intravenous leucovorin [200 mg/m2], and fluorouracil [400 mg/m2 bolus] all on day 1, and fluorouracil [2400 mg/m2 infusion] on days 1-2. In cycle two onwards, participants were administered intravenous trastuzumab-pkrb at 4 mg/kg and FOLFOX, every 2 weeks, until unacceptable toxic effects or disease progression. The primary endpoint of the study was objective response rate based on RECIST version 1.1, assessed in the participants who completed at least one study cycle. The response rate threshold for a positive objective response rate was 25%. This trial is registered with ClinicalTrials.gov (NCT04722133) and is ongoing. FINDINGS 34 participants were enrolled between June 26, 2020, and Sept 1, 2021. At the time of data cutoff on May 1, 2022, median follow-up was 13·0 months (IQR 11·0-16·9), with three participants remaining on treatment. Ten patients had a partial response and 17 had stable disease; the overall response rate was 29·4% (95% CI 16·7-46·3) and the disease control rate was 79·4% (95% CI 62·9-89·9). Median progression-free survival was 5·1 months (95% CI 3·6-6·7); median overall survival was 10·7 (95%CI 7·9-not reached). The most common treatment-related grade 3 or 4 adverse events were neutropenia (ten [29%] participants with grade 3 and nine [26%] with grade 4), grade 3 anaemia (five [15%] participants), and grade 3 peripheral sensory neuropathy (four [12%] participants). There were no treatment-related cardiac toxic effects or deaths. The overall health assessment (EuroQoL-VAS) score did not change significantly throughout the treatment. Sensory and motor neuropathy symptoms as assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy twenty-item scale questionnaire did not change significantly over time. INTERPRETATION For HER2-positive biliary tract cancer, second-line or third-line trastuzumab biosimilar plus FOLFOX exhibited promising activity with acceptable toxicity, warranting further investigation.

Abstract
Immune checkpoint inhibitor (ICI) became a standard treatment for advanced renal cell carcinoma (RCC). However, clinically valid biomarkers of therapeutic outcome are lacking. We investigated the role of interleukin-10 (IL-10) as a predictive biomarker for first-line ICI therapy in patients with advanced RCC. Baseline serum samples were prospectively collected and analyzed using a cytometric bead assay. Patients were divided into two groups according to their serum IL-10 levels using maximally selected rank statistics. A fraction (13.0%) of patients had high levels of serum IL-10 at baseline. High serum IL-10 levels (> 4.3 ng/mL) were associated with a significantly shorter progression-free (median: 5.2 months vs. not reached, P = 0.007) and overall survival (median: 13.9 months vs. not reached, P < 0.001). Multivariate Cox regression analysis confirmed the independent association between high serum IL-10 levels and poor survival outcomes. Effector cytokine production and the proliferative response of CD8+ T cells were significantly lower in patients with high serum IL-10 levels, who also had a shorter duration of response to first-line ICI therapy (4.6 months vs. not reached, P < 0.001). In conclusion, elevated serum IL-10 levels at baseline were associated with reduced clinical benefit from first-line ICI therapy in patients with advanced RCC.

Abstract
Sinapic acid (SA), a hydroxycinnamic acid, is known to confer protection against oxidative stress, inflammation, diabetes, and liver disease. However, the effectiveness of SA in improving obesity remains obscure. Therefore, this study evaluated anti-obesity efficacy of SA and to elucidate its mechanism of action. Male mice were maintained for 16 weeks on high-fat diet (HFD) alone or with SA (0.004%, w/w) and bodyweight, fat mass, adipocyte size, food intake, and biochemical and molecular markers were evaluated. SA-supplemented mice demonstrated markedly decreased fat mass and adipocyte size compared to unsupplemented group, without any changes in bodyweight and food intake between the two groups. Plasma adipocytokines levels including leptin, resistin, monocyte chemoattractant protein (MCP)-1 and interleukin-6 were also markedly reduced by SA supplementation. SA tended to lower plasma insulin level and improved homeostatic index of insulin resistance and intraperitoneal glucose tolerance test in HFD-induced obese mice. The anti-adiposity effect of SA was maybe owing to down-regulation of the mRNA expression of lipogenic genes, including acetyl coenzyme A (CoA) carboxylase, fatty acid synthesis, stearoyl-CoA desaturase 1, and phosphatidate phosphatase, and peroxisome proliferator-activated receptor γ, a transcription factor responsible for governing lipid metabolism, in adipose tissues. SA significantly down-regulated pro-inflammatory nuclear factor kappa B, MCP-1, tumor necrosis factor-α, and Toll-like receptor 4 mRNA expression in adipose tissue. Thus, SA could be beneficial for the development of functional foods or herbal medications to combat obesity.

Abstract
Importance Administration of atezolizumab could be immunogenic and induce undesirable antidrug antibody (ADA) responses. This may interfere with atezolizumab-mediated actions, affecting drug clearance and serum concentration or inducing antibody neutralization. Objective To determine the clinical and immunological associations of highly elevated ADA levels with clinical outcomes after atezolizumab/bevacizumab (Atezo/Bev) treatment in patients with advanced hepatocellular carcinoma (HCC). Design, Setting, and Participants This cohort study prospectively enrolled 174 patients with advanced HCC treated with first-line Atezo/Bev (discovery cohort: 61 patients from 1 center; validation cohort: 113 patients from 4 centers). Exposures Serum ADA levels at pretreatment and 3 weeks (cycle 2 day 1 [C2D1]) were analyzed using competitive enzyme-linked immunosorbent assays. In addition, samples were subjected to serological and flow cytometric analyses. Main Outcomes and Measures Overall, ADA positivity was associated with treatment outcomes and T-cell functions. Results After excluding patients with inadequate samples, follow-up loss, or consent withdrawal, 132 patients (discovery cohort: 50 patients; 41 [82.0%] men; median age [IQR], 61 [55-70] years; validation cohort: 82 patients; 70 [85.4%] men; median age [IQR], 61 [53-68] years) were analyzed, and robust ADA (≥1000 ng/mL) responses at C2D1 were identified in 23 (17.4%) of the patients. Patients with progressive disease exhibited higher ADA levels (median [IQR], 65.2 [0-520.4] ng/mL) at C2D1 than in responders (median [IQR], 0 [0-117.5] ng/mL). In both discovery and validation cohorts, patients with high ADA levels at C2D1 were associated with a reduced response rate (discovery cohort: 34% vs 11%; validation cohort: 29% vs. 7%) and worse progression-free survival (discovery cohort: hazard ratio [HR], 2.84; 95% CI, 1.31-6.13; P = .005; validation cohort: HR, 2.52; 95% CI, 1.27-5.01; P = .006) and overall survival (discovery cohort: HR, 3.30; 95% CI, 1.43-7.64; P = .003; validation cohort: HR, 5.81, 95% CI, 2.70-12.50; P = .001) with Atezo/Bev compared with those with low ADA levels. In multivariable Cox regression, the clinical implication of high ADA levels persisted even after adjusting for various confounding factors and was most significant at 1000 ng/mL or greater. Compared with patients with low ADA levels, patients with high ADA levels exhibited reduced serum atezolizumab concentrations, impaired CD8-positive T-cell proliferation, and had decreased interferon-γ and tumor necrosis factor-α from CD8-positive T cells compared with patients with low ADA levels. Conclusions and Relevance This cohort study found that highly elevated ADA levels at C2D1 may be associated with poor clinical outcomes in patients with advanced HCC treated with Atezo/Bev. High ADA levels may reduce atezolizumab exposure and attenuate the anticancer efficacy of the drug.

Abstract
In this multi-center phase II trial, we evaluated the efficacy and safety of a quadruplet regimen (pembrolizumab, trastuzumab, and doublet chemotherapy) as first-line therapy for unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer (AGC) (NCT02901301). The primary endpoints were recommended phase 2 dose (RP2D) for phase Ib and objective response rate (ORR) for phase II. The secondary endpoints included progression-free survival (PFS), overall survival (OS), duration of response, time to response and safety. Without dose-limiting or unexpected toxicities, the starting dose in the phase Ib trial was selected as RP2D. In 43 patients, the primary endpoint was achieved: the objective response rate was 76.7% (95% confidence interval [CI]: 61.4-88.2), with complete and partial responses in 14% and 62.8% of patients, respectively. The median progression-free survival, overall survival, and duration of response were 8.6 months, 19.3 months, and 10.8 months, respectively. No patients discontinued pembrolizumab because of immune-related adverse events. Programmed death ligand-1 status was not related to survival. Post hoc analyses of pretreatment tumor specimens via targeted sequencing indicated that ERBB2 amplification, RTK/RAS pathway alterations, and high neoantigen load corrected by HLA-B were positively related to survival. The current quadruplet regimen shows durable efficacy and safety for patients with HER2-positive AGC.

Abstract
BACKGROUND A growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy. MATERIALS AND METHODS We carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population. RESULTS One hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed. CONCLUSIONS The present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Abstract
BACKGROUND We aimed to compare the performance of established inflammation and nutrition-based prognostic indices with a relatively novel index 'mid-upper arm circumference (MUAC)' in outpatients with advanced cancer. METHODS This study was a secondary analysis of a prospective cohort study that enrolled 200 outpatients with advanced cancer visiting a medical oncology clinic at a tertiary hospital. All patients were followed until death, and the Glasgow Prognostic Score (GPS), modified GPS (mGPS), Prognostic Nutritional Index (PNI), neutrophil/lymphocyte ratio (NLR), C-reactive protein/albumin ratio (CAR), and MUAC were compared by calculating the area under the receiver operating characteristic curves (AUROCs). RESULTS The mean age of the patients was 64.4 years, 64.0% were male, and the median overall survival was 32.4 weeks [95% confidence interval (CI): 5.6-142.7]. Overall, all indices showed similarly high AUROCs for estimating 12-week (0.68 to 0.75) and 24-week survival (0.67 to 0.74). When confined to the GPS, mGPS, and MUAC, the AUROCs for 12-week survival were 0.75 (95% CI: 0.66-0.82), 0.74 (95% CI: 0.65-0.82), and 0.72 (95% CI: 0.64-0.79), respectively. For 24-week survival, the AUROCs were 0.70 (95% CI: 0.62-0.76), 0.67 (95% CI: 0.60-0.74), and 0.72 (95% CI: 0.64-0.79), respectively. MUAC had the highest specificity for estimating 12-week survival (86.0%), while GPS showed the highest sensitivity for estimating 12-week survival (81.1%). CONCLUSIONS Inflammation and nutrition-based prognostic indices showed similar acceptable accuracies in estimating the 12- and 24-week survival of oncology outpatients. Notably, a simple and non-invasive index MUAC, showed comparable performance with established indices including GPS and mGPS.

Abstract
OBJECTIVE Mid-upper arm circumference (MUAC) has been used to assess malnutrition and health status across various disease groups. However, it is unclear whether MUAC is associated with quality of life (QOL) of patients with advanced cancer. Our goal was to investigate the relationship between MUAC and QOL in ambulatory out-patients with advanced cancer. METHOD This was a cross-sectional study conducted in a tertiary cancer center in South Korea. A total of 200 patients with advanced cancer at oncology clinics of Seoul National University Bundang Hospital from March 2016 to January 2019 were enrolled. Out-patients with advanced cancer whose survival was expected to be less than one year by their oncologists were enrolled. QOL of patients was evaluated using the European Organization for Research and Treatment of Cancer quality of life questionnaire core 30 (EORTC QLQ-C30). Associations of QOL with MUAC and nutritional parameters were examined with generalized linear models. RESULTS The most common cancer sites were the lung, colon or rectum, and genitourinary tract. In univariate analyses, significant factors associated with higher summary score of EORTC QLQ-C30 were higher MUAC (≥ 26.5 cm, p < 0.001), higher body mass index (BMI) (≥ 22 kg/m2, p < 0.001), higher serum albumin (≥ 3.7 g/dL, p < 0.01), higher creatinine (≥ 0.8 mg/dL, p = 0.023), and higher uric acid (≥ 5 mg/dL, p < 0.01). In multivariate analysis, higher serum albumin (≥ 3.7 g/dL, p < 0.01) and higher MUAC (≥ 26.5 cm, p = 0.03) were independently associated with better summary score of EORTC QLQ-C-30. CONCLUSION MUAC was highly associated with QOL in terms of summary score and overall health status. Thus, MUAC, with its simplicity, can be a useful tool to reflect QOL in patients with advanced cancer.

Abstract
PURPOSE: Acute palliative care units (APCUs) are inpatient services in tertiary hospitals that provide intensive symptom management and assist in hospital discharge for transitions to hospice care. We aimed to analyze the clinical outcomes of operating an APCU at a comprehensive cancer center. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 1,440 consecutive patients admitted to the APCU and analyzed demographic and clinical information, discharge outcomes, symptom assessments using the Edmonton Symptom Assessment System, spiritual distress, and financial distress. RESULTS: The median age of patients was 67.0 (range, 23-97) years, and 41% were female. The most common primary cancer types were lung (21.9%), hepatopancreatobiliary (14.1%), and colorectal cancers (12.9%). The median length of stay was 8.0 days (range, 1-60 days), and 31.0% of patients died in the APCU. Death in the APCU showed a significant decrease over time, and overall inpatient death in oncology wards did not increase after APCU opening. In total, 44.7% of patients were discharged to government-certified hospice centers. The proportion of patients discharged to certified hospice centers increased from 32.2% in 2015 to 62.4% in 2018. Among 715 patients with a follow-up evaluation 1 week after admission, Edmonton Symptom Assessment System symptom scores, spiritual distress, and financial distress showed statistically significant improvements compared with the baseline symptom scores ( P < .001). This improvement was limited to patients who did not die in the APCU. CONCLUSION: Patients with advanced cancer admitted to the APCU may experience significant improvements in distressing symptoms. The majority of patients requiring transition to hospice were successfully transferred to certified hospice centers. The percentage discharged alive improved over time.

Predictive biomarkers of survival in patients with advanced hepatocellular carcinoma receiving atezolizumab plus bevacizumab treatment. Cancer Med 2022; 12:2731-2738. [PMID: 35997637 PMCID: PMC9939088 DOI: 10.1002/cam4.5161] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 07/28/2022] [Accepted: 08/11/2022] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND Since atezolizumab plus bevacizumab (ATE+BEV) regimen for patients with unresectable hepatocellular carcinoma (HCC) was released quite recently, real-world data are lacking. We evaluated efficacy, safety, and predictive biomarkers for survival in patients receiving ATE+BEV. METHODS Between 2020 and 2021, HCC patients receiving ATE+BEV at academic teaching hospitals were recruited. Treatment response was assessed using the Response Evaluation Criteria in Solid Tumors (version 1.1.). RESULTS Among 121 patients enrolled, the median age was 63 years, with male predominance (82.6%). Complete response, partial response, stable disease, and progressive disease were identified in 2.5%, 26.4%, 54.5%, and 16.6%, respectively. Patients with alpha-fetoprotein and des-gamma-carboxy prothrombin (DCP) response, defined as ≥30% and ≥50% decreases, respectively, at the first response evaluation relative to baseline, and those with neutrophil-to-lymphocyte ratio (NLR) <2.5, had significantly higher objective response rates (42.6% vs. 21.5%, 50.0% vs. 26.2%, and 39.0% vs. 19.4%, respectively; all p < 0.05). During follow-up, the median overall survival (OS) was not reached, and the median progression-free survival (PFS) was 5.7 months. Multivariable analyses showed that macrovascular invasion (adjusted hazard ratio [aHR] 2.541; p = 0.017), DCP ≥186 mAU/ml (aHR 5.102; p < 0.001), NLR ≥2.5 (aHR 3.584; p = 0.001), and an NLR decrease ≥10% at the first response (aHR 0.305; p = 0.002) were independent predictors of OS, and DCP ≥186 mAU (aHR 2.311; p = 0.002) and NLR ≥2.5 (aHR 1.938; p = 0.012) were independent predictors of PFS. Grade ≥3 treatment-related adverse events (AEs) occurred in 33 (27.3%) patients. CONCLUSION ATE+BEV showed favorable efficacy and safety. Baseline high DCP and NLR may be useful prognostic predictors for OS and PFS.

Abstract
Background Delirium is a neuropsychiatric condition strongly associated with poor clinical outcomes such as high mortality and long hospitalization. In the patients with Coronavirus disease 2019 (COVID-19), delirium is common and it is considered as one of the risk factors for mortality. For those admitted to negative-pressure isolation units, a reliable, validated and contact-free delirium screening tool is required. Materials and methods We prospectively recruited eligible patients from multiple medical centers in South Korea. Delirium was evaluated using the Confusion Assessment Method (CAM) and 4'A's Test (4AT). The attentional component of the 4AT was modified such that respondents are required to count days, rather than months, backward in Korean. Blinded medical staff evaluated all patients and determined whether their symptoms met the delirium criteria of the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). An independent population of COVID-19 patients was used to validate the 4AT as a remote delirium screening tool. We calculated the area under the receiver operating characteristic curve (AUC). Results Out of 286 general inpatients, 28 (9.8%) inpatients had delirium. In this population, the patients with delirium were significantly older (p = 0.018) than the patients without delirium, and higher proportion of males were included in the delirium group (p < 0.001). The AUC of the 4AT was 0.992 [95% confidence interval (CI) 0.983-1.000] and the optimal cutoff was at 3. Of the independent COVID-19 patients, 13 of 108 (12.0%) had delirium. Demographically, the COVID-19 patients who had delirium only differed in employment status (p = 0.047) from the COVID-19 patients who did not have delirium. The AUC for remote screening using the 4AT was 0.996 (0.989-1.000). The optimal cutoff of this population was also at 3. Conclusion The modified K-4AT had acceptable reliability and validity when used to screen inpatients for delirium. More importantly, the 4AT efficiently screened for delirium during remote evaluations of COVID-19 patients, and the optimal cutoff was 3. The protocol presented herein can be used for remote screening of delirium using the 4AT.

Abstract
Purpose: Inter-tumoral heterogeneity at the differential lesion level raises the possibility of distinct organ-specific responses to immune checkpoint inhibitors (ICIs). We aimed to comprehensively examine the clinicopathological factors to predict and assess the efficacy of nivolumab, programmed cell death protein 1 (PD-1) blockade at an individual tumor site-specific level in patients with advanced hepatocellular carcinoma (aHCC). Patients and Methods: We enrolled 261 aHCC patients treated with nivolumab between 2012 and 2018. Eighty-one clinicopathological factors were comprehensively collected and analyzed. The association between all variables and survival outcomes was evaluated. According to tumor site, the organ-specific responses were assessed based on the Response Evaluation Criteria in Solid Tumors, version 1.1. Results: The liver was the most commonly involved organ (75.1%), followed by the lungs (37.5%) and lymph nodes (LNs, 11.5%). The liver of nonresponders was more frequently the organ of progression, while the lungs of responders were more frequently the organs of response. Among the 455 individual lesions (liver, n = 248; lung, n = 124; LN, n = 35; others including bone or soft tissues, n = 48), intrahepatic tumors showed the least response (10.1%), followed by lung (24.2%) and LN tumors (37.1%), indicating the presence of distinct organ-specific responses to nivolumab. In intrahepatic tumors, the organ-specific response rate decreased as the size increased (13% for ⩽50 mm, 8.1% for 50–100 mm, and 5.5% for >100 mm). In the subgroup analysis according to tumor location, patients with lung only metastasis (⩾30 mm) showed the best progression-free survival (PFS) and overall survival (OS). In contrast, primary HCC (⩾100 mm) without lung metastasis had the worst PFS and OS. Comprehensive analyses also revealed that liver function and systemic inflammatory indices, such as neutrophil-to-lymphocyte ratio (NLR), were significantly associated with PFS and OS. Conclusion: The presence and size of liver tumors, liver function, and NLR are key factors determining the response to nivolumab in aHCC. These clinical factors should be considered when treating patients with advanced HCC with PD-1 blockade.

Abstract
Abstract
Introduction: Tumor vasculature plays an important role in promoting tumor progression and immune evasion. Previously, we developed PB101, a novel glycosylated decoy receptor that can neutralize VEGF-A, VEGF-B, and PlGF, and demonstrated that it potently inhibits tumor angiogenesis, thereby retarding tumor growth and metastasis. However, its impact on tumor microenvironment (TME), especially anti-cancer immunity, has not been fully elucidated. Here, we investigated distinct modes of immune modulation by PB101 compared with other anti-angiogenic agents, and evaluated its immunotherapeutic potential when combined with immune checkpoint inhibitors (ICIs).
Methods: MC38 colon or Hepa-V liver cancer-bearing mice were treated with PB101 or other anti-angiogenic agents with or without various ICIs. The TME was evaluated by histologic, flow cytometric, and Nanostring immune profiling analyses.
Results: PB101 markedly suppressed MC38 colon and Hepa-V liver cancer growth in vivo. It simultaneously inhibited both VEGF and PlGF signaling within the TME, thus suppressing tumor angiogenesis. PB101 also induced extensive immune remodeling of the TME. PB101 enhanced intratumoral dendritic cells, but reduced M2-like tumor-associated macrophages. Moreover, PB101 resulted in high influx of activated CD8+, but not CD4+, T cells into the TME. PB101 exhibited the most prominent immune-modulating effect compared with other vascular targeting agents. When combined with various ICIs, PB101 had the greatest synergism with anti-PD-L1 antibody, inducing complete tumor regression and long-term survival. Furthermore, PB101-based combination immunotherapy induced a durable and protective immunity against subcutaneous tumor re-challenge and hematogenous lung metastasis.
Conclusion: PB101 elicited strong anti-tumor immunity more effectively than other anti-angiogenic agents. PB101 can strengthen the immunotherapeutic efficacy of PD-L1 inhibitor by establishing a potent and durable immune memory. The combination of PB101 and PD-LI needs to be further validated in clinical trials.

Abstract
4105 Background: Systemic administration of humanized monoclonal antibodies can be immunogenic and trigger unwanted anti-drug antibody (ADA) responses. In the IMbrave 150 study, 29.6% of advanced hepatocellular carcinoma (HCC) patients developed atezolizumab ADAs after atezolizumab and bevacizumab (atezo/bev) treatment. ADAs could impair the action of the therapeutic antibody by reduction of serum concentration or neutralization. We determined the clinical and immunological implications of high ADA levels in advanced HCC patients after atezo/bev treatment. Methods: Advanced HCC patients (n = 132) treated with first-line atezo/bev were prospectively enrolled (discovery cohort: 50 from an institute; validation cohort: 82 from four institutes). Serum levels of atezolizumab ADA at baseline and three weeks (C2D1) and atezolizumab concentrations at C2D1 were measured by competitive ELISA. The effects of ADA on T cell immunity were examined by multiplex flow cytometry. Results: Strong ADA (≥ 1000 ng/ml) responses at C2D1 were observed in 17.4% of advanced HCC patients. ADA elevation after atezo/bev at C2D1 was evident in non-responders but not significant in responders. In the discovery cohort, patients with high ADA at C2D1 showed a decreased response rate (ADA-high: 11% and ADA-low: 34%) and shorter progression-free survival (PFS) and overall survival (OS) with atezo/bev compared to those with low ADA levels ( P = 0.004 for PFS; P = 0.009 for OS). In the validation cohort, patients with high ADA at C2D1 showed reduced response rate than those with low ADA (ADA-high: 7% and ADA-low: 29%). PFS and OS were worse in ADA-high group than in ADA-low group ( P = 0.001 for PFS; P < 0.001 for OS). In multivariate Cox regression analysis, the clinical significance of high ADA levels was independently associated with shorter PFS and OS after adjustment for age, sex, ECOG performance status, Child-Pugh score, AFP, macroscopic vascular invasion, extrahepatic spread, and neutrophil-to-lymphocyte ratio (PFS: HR 2.27, P = 0.006; OS: HR 3.04, P = 0.006). The atezolizumab serum concentrations were 29.8% lower in patients with high ADA levels than in ADA-negative patients. Atezolizumab concentration at C2D1 was inversely correlated with ADA levels. Moreover, patients with high ADA lacked CD8+ T cell proliferative responses to atezo/bev treatment. Furthermore, patients with high ADA had decreased secretion of effector cytokines such as IFN-γ and TNF-α from CD8+ T cells compared to those with low ADA. Conclusions: Highly elevated ADA at C2D1 is associated with unfavorable clinical outcomes in advanced HCC patients treated with atezo/bev. High ADA levels were associated with reduced atezolizumab exposure and could limit the drug’s anti-cancer efficacy.

Abstract
4076 Background: Anti-PD-1 monotherapy elicits various organ-specific immune responses. Although advanced hepatocellular carcinoma (aHCC) showed 20–40% objective response rates (ORR) for cases of extrahepatic lesions in sites such as the lungs or lymph nodes (LNs), only 10% of intrahepatic lesions responded to the monotherapy. The organ-specific responses were due to tumor heterogeneity and differential microenvironments, and may have contributed to the failure of the phase III trials of anti-PD-1 monotherapy for aHCC. Recently, the combination of atezolizumab and bevacizumab (Ate/Bev) as first-line systemic treatment has resulted in survival benefits for patients with aHCC. However, the organ-specific response for this treatment has not been explored. We aimed to evaluate the organ-specific response to Ate/Bev combination therapy in patients with aHCC. Methods: We enrolled patients who received first-line Ate/Bev treatment for aHCC. Eligible patients included those with Child-Pugh A liver function, measurable tumor lesions, and serial image studies available for response evaluation. An independent radiologist reviewed the tumors located in the liver, lungs, LNs, and other sites. Organ-specific response criteria, adapted from RECIST 1.1 and immune-related RECIST, were used. Results: Between May 2020 and June 2021, 124 patients from two Korean cancer referral institutions received first-line Ate/Bev treatment for aHCC. The patient baseline characteristics included: hepatitis B (n = 85, 68.5%), hepatitis C (n = 6, 4.8%), non-viral (n = 33, 26.7%); BCLC stage A/B/C (n = 2, 1.6%/n = 19, 15.3%/n = 103, 83.1%); macrovascular invasion (n = 39, 31.5%); extrahepatic metastasis (n = 75, 60.5%); and AFP >400 ng/ml (n = 39, 31.5%). The median age was 62 years (range: 34–90). With median follow-up duration of 10.1 months, median progression-free survival was 6.8 months (95% CI, 3.6–10.0) and median overall survival was 16.9 months (95% CI, range not available). The ORR was 29.8%. For 260 individual tumor lesions, the liver was the most commonly involved organ (n = 152, 58.5%), followed by the LNs (n = 42, 16.2%) and lungs (n = 24, 9.2%). Ate/Bev treatment induced potent tumor shrinkage in both intrahepatic and extrahepatic lesions: ORR for hepatic lesions was 28.3%; LN lesions, 40.5%; lung lesions, 29.1%; and other metastatic lesions, 19.0%. Further, the organ-specific response rate for intrahepatic tumors decreased as the tumor size increased (36.7%: ≤50 mm, 13.0%: >50 mm). Conclusions: Unlike anti-PD-1 monotherapy, Ate/Bev combination therapy showed favorable responses even in intrahepatic lesions, which are comparable to those in extrahepatic lesions. As such, Ate/Bev may overcome an immune-tolerant hepatic microenvironment in patients with aHCC. (NCT04862949).

Abstract
Background: Cabozantinib, a multiple kinase inhibitor, was recently approved for patients with previously treated unresectable hepatocellular carcinoma (uHCC). We investigated the real-world safety and efficacy profiles of cabozantinib. Methods: This multicenter retrospective study included 110 patients with uHCC who received cabozantinib after progression on other systemic treatments between October 2019 and May 2021. Results: The median age was 58 (range, 20–77) years, and 98 (89.1%) were male. Prior to cabozantinib, all patients were treated with other systemic therapies: sorafenib (n = 104, 94.5%) and regorafenib (n = 91, 82.7%) were the most commonly used agents. Immune checkpoint inhibitors were previously used in 93 patients (84.5%). Cabozantinib was used beyond the third-line of therapy in most patients (n = 90, 81.8%). With a median follow-up duration of 11.9 months [95% confidence interval (CI), 10.8–17.2], the median progression-free survival (PFS) was 3.7 months (95% CI, 3.1–4.9), and the median overall survival (OS) was 7.5 months (95% CI, 5.5–9.5). The disease control rate and overall response rate (ORR) were 66.3% and 3.6%, respectively. In the Child–Pugh A cohort (n = 88), the ORR was 4.5%, and the median PFS and OS were 4.3 months (95% CI, 3.6–5.8) and 9.0 months (95% CI, 7.5–11.7), respectively. Conclusion: Cabozantinib showed consistent efficacy outcomes with a prior phase III trial, although in this study, it was used as later-line therapy for patients who were refractory to multiple systemic treatments, including immune checkpoint inhibitors.

Abstract
Background
We aimed to investigate the performance of clinician prediction of survival (CPS) and the association between CPS and the prognostic confidence of clinicians in ambulatory medical oncology outpatients.
Methods
Eight medical oncologists estimated the expected survival of their patients in a prospective cohort study. They were asked to provide a temporal type of CPS in weeks, together with their level of confidence for each prediction (0–100%). We analyzed the accuracy of CPS, the association between CPS and the prognostic confidence, and the characteristics of patients showing inaccurate CPS.
Results
A total of 200 advanced cancer patients were enrolled and the median overall survival was 7.6 months. CPS was accurate in 67 (33.5%) patients, underestimated in 87 (43.5%), and overestimated in 46 (23.0%). The overall accuracy of CPS for 12-week, 24-week, 36-week, and 48-week survival was 83.0%, 72.0%, 75.5%, and 74.0%, respectively. The specificity was highest for 12-week survival (90.2%) and the sensitivity was highest for 48-week survival (96.1%). The sensitivity of 12-week CPS was 51.4% and the area under the receiver operating characteristic (AUROC) curve was 0.79 (95% confidence interval [CI] 0.71–0.87). The prognostic confidence of clinicians was not significantly associated with the accuracy of prediction (P = 0.359). Patients with overestimated survival had significantly poorer global health status and physical/role/emotional functioning in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Additionally, they showed significantly higher levels of fatigue, nausea/vomiting, pain, dyspnea, and loss of appetite.
Conclusion
The overall accuracy of CPS in predicting 12-week to 48-week survival was high in medical oncology outpatients. However the sensitivity of 12-week CPS was low and prognostic confidence was not associated with the accuracy of CPS. Patients with overestimated CPS showed poorer quality of life and higher symptom burden.

Abstract
Lenvatinib (LENV) and atezolizumab/bevacizumab (ATE/BEV) have been approved as first-line regimens for the treatment of unresectable hepatocellular carcinoma (HCC). We aimed to compare their clinical efficacy and safety. Patients receiving ATE/BEV (n = 86) or LENV (n = 146) as first-line treatment were recruited from three academic hospitals in Korea. Overall survival (OS), progression-free survival (PFS), and radiological response were assessed according to the Response Evaluation Criteria in Solid Tumors. Clinical features of the two groups were balanced through propensity score (PS) matching with a 1:1 ratio and inverse probability of treatment weighting (IPTW) analyses. The median age was 62 years, with male predominance (83.6%). There was no significant difference in the objective response rate between the ATE/BEV and LENV groups (32.6% vs. 31.5%; p = 0.868). Neither median OS (not reached vs. 12.8 months; p = 0.357) nor PFS (5.7 vs. 6.0 months; p = 0.738) was different between ATE/BEV and LENV groups. PS-matched and IPTW analyses yielded comparable results in terms of OS and PFS (all p > 0.05). Grade ≥ 3 adverse events occurred in 42.8% and 21.9% of patients in the ATE/BEV and LENV groups, respectively (p = 0.141). The two first-line therapy regimens for unresectable HCC had comparable clinical efficacy and safety in real-world practice settings. Further studies with a larger sample size and longer follow-up are needed to validate these results.

The Qilianyu cluster of the Xisha (Paracel) Islands has one of the few remaining green turtle Chelonia mydas rookeries in the China region. Genetic samples were obtained from dead green turtle embryos and hatchlings salvaged from post-hatched nests at Middle Island (n = 3), North Island (n = 9) and South Sand (n = 1) of the Qilianyu cluster in 2017-2019. The ~800 bp mitochondrial DNA control region was sequenced from the samples, and 5 haplotypes were identified belonging to 2 documented clades (clades III and VIII), including 2 new haplotypes (CmP243.1 and CmP244.1) and 3 previously reported haplotypes (CmP18.1, CmP19.1, CmP20.1). These results were combined with previously published mtDNA data for the Qilianyu cluster and nearby (~93 km) Yongle Islands indicating a lack of differentiation based on truncated 384 bp control region sequences (exact test, p = 0.0997; FST = 0.015, p = 0.2760), to represent a single Xisha Islands rookery. The rookery at the Xisha Islands was significantly differentiated (p < 0.01) from all 19 management units (MUs) documented in the Indo-Pacific and Japan regions, supporting recognition of the Xisha Islands rookery as a new independent MU. The results will help inform national and international conservation action plans by China and the countries around the South China Sea to protect green turtles in the West Pacific Ocean.

Abstract
TPS490 Background: In biliary tract cancer (BTC), there was a positive association of overall survival (OS) with high levels of tumor-infiltrating CD4+, CD8+, and Foxp3+ T lymphocytes, whereas increases in PD-1+/CD8+ tumor-infiltrating lymphocytes had a negative association with OS (Tariq NU et al. 2018). Therefore, immune-modulating treatment can be promising option to overcome a dismal prognosis in BTC patients. However, immune checkpoint inhibitor (ICI) monotherapy, including tislelizumab (anti-PD-1 monoclonal antibody), has a modest effect in advanced BTC (Desai J et al. 2020). Thus, several combination strategies to improve the anti-tumor effect of ICI are being conducted. Anti-angiogenic agent in combination with ICI is one of the promising strategies in which anti-angiogenic agent induced improved anti-tumor immune responses by increasing tumor antigen presentation and promoting lymphocyte infiltration and migration (Song Y et al. 2020). However, this combination have not been widely tested in BTC patients. Sitravatinib is a potent inhibitor of multiple receptor tyrosine kinases including Axl, MER, MET, KIT, FLT3, RET, VEGFR1-3, PDGFRα, which targets are expressed in a number of immune cell types and promote an immunosuppressive tumor microenvironment. This study aim to evaluate the efficacy of the combination strategy of sitravatinib with tislelizumab in advanced BTC and to reveal the immune-modulation through the combination of ICI and antiangiogenic agents. Methods: This study is an open-label, phase 2 study to evaluate the efficacy of sitravatinib and tislelizumab combination treatment in advanced BTC patients who have failed to first-line chemotherapy. Eligible patients have histologically proven BTC (including intrahepatic cholangiocarcinoma, extrahepatic bile duct cancer, gallbladder cancer, and ampulla of Vater cancer) and have failed one prior systemic chemotherapy. Patients who have previously received ICI can be enrolled. However, patients who have experienced unacceptable toxicity during prior ICI treatment are excluded. All patients will receive sitravatinib 120mg orally once daily in combination with tislelizumab 200mg intravenously once every 3 weeks until disease progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint is disease control rate, with key secondary endpoints including overall response rate, progression-free survival, overall survival, and safety. For evaluating metabolic response, 18F-FDG PET-CT scan will be performed before treatment and at the first response evaluation. Tissue biopsies will be conducted three times in total: screening, the first response evaluation, and disease progression. Blood samples are being collected every cycles for translational biomarker studies. Clinical trial information: NCT04727996.

Abstract
415 Background: The immunomodulatory effect of regorafenib may enhance the anti-tumor activity of nivolumab in patients with uHCC. We report results from a phase 2 study of regorafenib plus nivolumab as first-line therapy in patients with uHCC. Methods: In this open-label, multi-center, single-arm study, patients with >19 years, ECOG PS 0 or 1, BCLC stage B or C, and no prior systemic therapy were eligible. Patients received intravenous nivolumab 480 mg, every 4 weeks, and oral regorafenib 80 mg daily, 3 weeks on/1 week off, every 4 weeks. Tumor response was evaluated per RECIST v1.1, every 8 weeks (fixed schedule). Primary endpoint was overall response rates (ORR) per RECIST v1.1. Secondary endpoints were progression-free survival (PFS), overall survival (OS), ORR per mRECIST, and safety profile per NCI-CTCAE v5. Results: A total of 42 patients were enrolled between JUL-2020 and JAN-2021. Median age was 61 years (range, 40-79), and 31 patients (73.8%) were male. Most patients had BCLC C stage (n=38, 90.5%) and hepatitis B virus infection (n=30, 71.4%). Extrahepatic metastasis was noted in 36 patients (85.7%) and baseline serum AFP levels were >400 ng/mL in 17 patients (40.5%). With median follow-up duration of 9.2 months (95% CI, 8.5-9.9 months), 21 patients were ongoing in this study. ORR per RECIST v1.1 was 31.0% (CR 1 [2.4%] and PR 12 [28.6%]), and ORR per mRECIST was 35.7% (CR 4 [9.5%] and PR 11 [26.2%]). Median PFS was 5.5 months (95% CI, 1.8-9.1 months) and median OS was not reached. The 6-months PFS and OS were 49.9% and 90.4%. Most common adverse events were hand-foot skin reaction (n=14, 33.3%), skin rash (12, 28.5%), and alopecia (10, 23.8%). Conclusions: Regorafenib plus nivolumab shows promising efficacy outcomes in uHCC. There was no unexpected safety signals and most of toxicities were manageable. Clinical trial information: NCT04310709.
