Abstract
This study focused on investigating the potential of Artificial Intelligent-powered Virtual Assistants (VAs) such as Amazon Alexa, Apple Siri, and Google Assistant as tools to help individuals seeking information about Nicotine Replacement Treatment (NRT) for smoking cessation. The researchers asked 40 NRT-related questions to each of the 3 VAs and evaluated the responses for voice recognition. The study used a cross-sectional mixed-method design with a total sample size of 360 responses. Inter-rater reliability and differences between VAs' responses were examined by SAS software, and qualitative assessments were conducted using NVivo software. Google Assistant achieved 100% voice recognition for NRT-related questions, followed by Apple Siri at 97.5%, and Amazon Alexa at 83.3%. Statistically significant differences were found between the responses of Amazon Alexa relative to both Google Assistant and Apple Siri. Researcher 1's ratings significantly differed from Researcher 2's (p = .001), but not from Researcher 3's (p = .11). Virtual Assistants occasionally struggled to understand the context or nuances of questions, lacked in-depth information in their responses, and provided generic or unrelated responses. Virtual Assistants have the potential to be incorporated into smoking cessation interventions and tobacco control initiatives, contingent upon improving their competencies.

Abstract
BACKGROUND Anxiety- and cancer-related neuropathy are two persistent effects related to treatment for cancer. Mindfulness meditation has been used with substantial impact as a nonpharmacologic intervention to mitigate side and late effects of treatment. Mobile apps are ubiquitous for most of the general population, yet have a particular relevance for cancer survivors, given that physical and geographic limitations can be present. OBJECTIVE This study aims to describe an ongoing trial of the Mindfulness Coach mobile app for cancer survivors. METHODS In this randomized waitlist controlled trial, cancer survivors experiencing anxiety- or cancer-related neuropathy (200 for neuropathy and 200 for anxiety) and who had finished primary cancer treatment were invited to participate. Data were collected at 3 time points regardless of randomization condition: baseline, 8 weeks, and 16 weeks. Both face-to-face and web-based recruitment strategies were used. The trial was opened for 2 separate primary outcomes (anxiety- or cancer-related neuropathy). The goal was not to compare these groups but to compare treatment and waitlist groups for each condition. In addition to evaluating the impact of mobile mindfulness on reported anxiety- or cancer-related neuropathy, other pain, fatigue, trauma, sleep, and satisfaction with the Mindfulness Coach app will also be assessed. RESULTS Outcomes of the study are expected in early 2024. CONCLUSIONS Mindfulness meditation has become widely practiced, and the use of mobile technology has become ubiquitous. Finding ways to deliver mindfulness meditation to people who have been treated for cancer allows for the intervention to be accessible to a larger number of survivors. The results of this intervention could have implications for further understanding the impact of mindfulness meditation on 2 persistent side and late effects of treatment of cancer, namely anxiety- and cancer-related neuropathy.

Abstract
Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formation and evolution remain poorly understood3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

Abstract
Mesothelioma is a cancer typically caused by asbestos. Mechanistically, asbestos carcinogenesis has been linked to the asbestos-induced release of HMGB1 from the nucleus to the cytoplasm, where HMGB1 promotes autophagy and cell survival, and to the extracellular space where HMGB1 promotes chronic inflammation and mesothelioma growth. Targeting HMGB1 inhibited asbestos carcinogenesis and the growth of mesothelioma. It is hoped that targeting HMGB1 will be a novel therapeutic strategy that benefits mesothelioma patients. Severe restrictions and/or a complete ban on the use of asbestos were introduced in the 80 and early 90s in the Western world. These measures have proven effective as the incidence of mesothelioma/per 100,000 persons is decreasing in these countries. However, the overall number of mesotheliomas in the Western world has not significantly decreased. There are several reasons for that which are discussed here: (1) the presence of asbestos in old constructions; (2) the development of rural areas containing asbestos or other carcinogenic mineral fibers in the terrain; (3) the discovery of an increasing fraction of mesotheliomas caused by germline genetic mutations of BAP1 and other tumor suppressor genes; (4) mesotheliomas caused by radiation therapy; (5) the overall increase in the population and of the fraction of older people who are much more susceptible to develop all types of cancers, including mesothelioma. In summary, the epidemiology of mesothelioma is changing, the ban on asbestos worked, there are opportunities to help mesothelioma patients especially those who develop in a background of germline mutations and there is the opportunity to prevent a mesothelioma epidemic in the developing world, where the use of asbestos is increasing exponentially. We hope that restrictive measures similar to those introduced in the Western world will soon be introduced in developing countries to prevent a mesothelioma epidemic.

Abstract
Background Physical activity improves health and psychosocial functioning for people who have been diagnosed with cancer. Native Hawaiians face disparities for some cancers, including breast cancer. Delivering culturally grounded interventions has the potential to improve enjoyment and adherence to the intervention. We sought to test the adherence and impact of a 6 month randomized wait-list controlled trial of hula. Methods In this randomized wait-list controlled design people who had been diagnosed with breast or gynecologic cancers were invited to participate with other cancer survivors in a group based setting. Participants were randomized to begin hula immediately or after six months. Attendance was collected and heart-rate measured three times per session. In addition, demographic data, self-report psychosocial data, and biological data (findings will be reported elsewhere) were collected at three time points: baseline, 6 months, and 12 months. The study included six months of hula, twice per week, 60 min each session. In addition, participants committed to practice 60 min per week at home. Results Participants in the study (n = 42) attended, on average, 72% of the sessions. Significant increase in moderate physical activity (d = 0.50, p = 0.03) was observed in the intervention versus control group. For the measures of intra-individual changes pre-and post-intervention, an increase in total physical activity were seen in the intervention group (d = 0.69, p = 0.003), daily caloric intake decreased (d = -0.62, p = 0.007), and a reduction in waist circumference (d = -0.89, p = 0.0002) that was sustained six months after completion of the intervention. Psychosocially, cognitive functioning significantly declined from baseline to 12 months (d = -0.50, p = 0.03), with role functioning improving (d = 0.55, p = 0.02), social constraints increasing (d = 0.49, p = 0.03), and financial difficulties improving (d = -0.55, p = 0.02). Conclusion Sustainable physical activity is crucial to improve both the survival and quality of life of cancer survivors. Culturally grounded interventions, such as hula have the potential to increase the maintenance of physical activity. In addition, they create a support group where the benefits of people who have all experienced cancer can gather and garner those benefits of social support, too. This study was registered as a clinical trial through the National Cancer Institute (NCT02351479). Clinical trial registration Clinicaltrails.gov, NCT02351479.

Abstract
Asbestos is the main cause of malignant mesothelioma. Previous studies have linked asbestos-induced mesothelioma to the release of HMGB1 from the nucleus to the cytoplasm, and from the cytoplasm to the extracellular space. In the cytoplasm, HMGB1 induces autophagy impairing asbestos-induced cell death. Extracellularly, HMGB1 stimulates the secretion of TNFα. Jointly, these two cytokines kick-start a chronic inflammatory process that over time promotes mesothelioma development. Whether the main source of extracellular HMGB1 were the mesothelial cells, the inflammatory cells, or both was unsolved. This information is critical to identify the targets and design preventive/therapeutic strategies to interfere with asbestos-induced mesothelioma. To address this issue, we developed the conditional mesothelial HMGB1-knockout (Hmgb1ΔpMeso) and the conditional myelomonocytic-lineage HMGB1-knockout (Hmgb1ΔMylc) mouse models. We establish here that HMGB1 is mainly produced and released by the mesothelial cells during the early phases of inflammation following asbestos exposure. The release of HMGB1 from mesothelial cells leads to atypical mesothelial hyperplasia, and in some animals, this evolves over the years into mesothelioma. We found that Hmgb1ΔpMeso, whose mesothelial cells cannot produce HMGB1, show a greatly reduced inflammatory response to asbestos, and their mesothelial cells express and secrete significantly reduced levels of TNFα. Moreover, the tissue microenvironment in areas of asbestos deposits displays an increased fraction of M1-polarized macrophages compared to M2 macrophages. Supporting the biological significance of these findings, Hmgb1ΔpMeso mice showed a delayed and reduced incidence of mesothelioma and an increased mesothelioma-specific survival. Altogether, our study provides a biological explanation for HMGB1 as a driver of asbestos-induced mesothelioma.

Abstract
OBJECTIVE The prevalence of asthma and chronic obstructive pulmonary disorder (COPD) is elevated for Native Hawaiians but the basis for this differential is not well understood. We analyze data on asthma and COPD in two samples including Native Hawaiians Pacific Islanders, and Filipinos to determine how ethnicity is related to respiratory disease outcomes. METHODS We analyzed the 2016 and 2018 Behavioral Risk Factor Surveillance Survey (BRFSS), a telephone survey of participants ages 18 and over in the State of Hawaii. Criterion variables were a diagnosis of asthma or COPD by a health professional. Structural equation modeling tested how five hypothesized risk factors (cigarette smoking, e-cigarette use, second-hand smoke exposure, obesity, and financial stress) mediated the ethnic differential in the likelihood of disease. Age, sex, and education were included as covariates. RESULTS Structural modeling with 2016 data showed that Native Hawaiian ethnicity was related to higher levels of the five risk factors and each risk factor was related to a higher likelihood of respiratory disease. Indirect effects were statistically significant in almost all cases, with direct effects to asthma and COPD also observed. Mediation effects through comparable pathways were also noted for Pacific Islanders and Filipinos. These findings were replicated with data from the 2018 survey. CONCLUSIONS Native Hawaiian and Pacific Islander ethnicity is associated with greater exposure to five risk factors and this accounts in part for the ethnic differential in respiratory disease outcomes. The results support a social-ecological model of health disparities in this population. Implications of the findings for preventive interventions are discussed.

Abstract
Knowledge about the respiratory health consequences of adolescents' use of tobacco products with cannabis remains limited. We studied whether e-cigarettes, combustible cigarettes, and cannabis were independently associated with asthma in a population-based sample of 150,634 public high school students (10th and 12th graders), drawn in a two-stage design to be representative of the state of California in 2019-2020. Measures were obtained for use of e-cigarettes, combustible cigarettes, and cannabis; motives for use (three substances); method of use (for cannabis); ever being diagnosed with asthma; and having an asthma attack in past 12 months. Cross-classification indicated Nonuse for 64% of the sample; 15% Dual E-cigarette/Cannabis Use; 10% Exclusive Cannabis Use; 5% Exclusive E-cigarette Use; and 5% Triple Use. Multinomial logistic regression with a three-level criterion variable, controlling for age, sex, parental education, race/ethnicity, and three types of household use showed that compared with Nonuse, odds of Lifetime Asthma (vs. Never Had) was elevated for Triple Use (AOR = 1.14, CI 1.06-1.24), Dual E-cigarette/Cannabis Use (1.17, 1.12-1.23), Exclusive Cannabis Use (1.17, 1.11-1.23), and Exclusive E-cigarette Use (1.10, 1.02-1.18). Similar results were noted for Recent Asthma. Among persons who had used cannabis, 88% of the Triple group and 74% of the Dual E-cigarette/Cannabis group reported both smoking and vaping cannabis. Thus, co-occurrence of e-cigarette and cannabis use was a common pattern among adolescents in this study, and subgroups of cannabis and e-cigarette use showed similar associations with asthma. Preventive approaches should highlight the health implications of exclusive or combined e-cigarette and cannabis use.

Abstract
PURPOSE Bladder cancer (BCa) is one of the most common cancer types worldwide and is characterized by a high rate of recurrence. In previous studies, we and others have described the functional influence of plasminogen activator inhibitor-1 (PAI1) in bladder cancer development. While polymorphisms in PAI1 have been associated with increased risk and worsened prognosis in some cancers, the mutational status of PAI1 in human bladder tumors has not been well defined. METHODS In this study, we evaluated the mutational status of PAI1 in a series of independent cohorts, comprised of a total of 660 subjects. RESULTS Sequencing analyses identified two clinically relevant 3' untranslated region (UTR) single nucleotide polymorphisms (SNPs) in PAI1 (rs7242; rs1050813). Somatic SNP rs7242 was present in human BCa cohorts (overall incidence of 72%; 62% in Caucasians and 72% in Asians). In contrast, the overall incidence of germline SNP rs1050813 was 18% (39% in Caucasians and 6% in Asians). Furthermore, Caucasian patients with at least one of the described SNPs had worse recurrence-free survival and overall survival (p = 0.03 and p = 0.03, respectively). In vitro functional studies demonstrated that SNP rs7242 increased the anti-apoptotic effect of PAI1, and SNP rs1050813 was related to a loss of contact inhibition associated with cellular proliferation when compared to wild type. CONCLUSION Further investigation of the prevalence and potential downstream influence of these SNPs in bladder cancer is warranted.

Abstract
Abstract
Background: Breast cancer survivors have an increased risk for comorbid conditions such as cardiovascular disease, diabetes, and hypertension. In addition, cancer related treatments negatively affect bone health, muscular strength, and quality of life. Exercise is an effective strategy to combat cancer related symptoms (fatigue, anxiety) and common comorbid conditions. MOTS-c is a Mitochondrial Derived Peptide (MDP) that has a number of beneficial effects on metabolism, insulin sensitivity, and exercise capacity. Previously published preclinical studies have shown that MOTS-c treatment improves physical performance in young, middle-age, and old mice. In humans, it has been implicated to promote metabolic homeostasis, stimulate glucose utilization, fat-oxidation, reduce inflammation, and protect against both cardiovascular and metabolic disease. We implemented a 12-week exercise program in breast cancer survivors. We evaluated changes in baseline and post12-week MOTS-c levels and corresponding body composition changes.
Methods: We evaluated 25 participant paired samples at baseline and post 12-weeks of exercise. Participants engaged in a 12-week exercise program, 3 times a week for 90 minutes/session. At baseline and post 12-weeks, participants underwent a DXA scan, body composition analysis, and a blood draw. The blood samples were analyzed using an in-house ELISA and compared to various clinical and body composition metrics.
Results: The median age was lowest for the high responders (56.7 years) compared to moderate responders (57 years) and reduced MOTS-c (61.5 years). We found 3 distinct groups: reduced MOTS-c with exercise (n=8), increased MOTS-c moderate responders (0-10pg/ml; n=2), and increased MOTS-c high responders (>10 pg/ml; n=15). MOTS-c had an inverse relationship with almost all tested metrics including: age, weight, BMI, waist to hip ratio, body composition—visceral (fat area, fat mass, fat volume), subcutaneous fat mass, whole body (body lean, body mass, body percent fat, bone mineral content (BMC), and bone mineral density (BMD). Although the majority of the metrics improved and had inverse relationships for MOTS-c, the reduced MOTS-c group had increased BMC and BMD. Interestingly, despite a higher MOTS-c value, there was an increase in visceral fat as well as an increase in whole body fat across all groups. Of the 25 participants, 22 were Asian, two were Caucasian, and one was Native Hawaiian/Pacific Islander. Given the small number of participants, there does not appear to be any correlation between MOTS-c and ethnicity in our study.
Summary: We found significant changes in MOTS-c according to clinical and body composition metrics after a 12-week exercise program. The findings in this study support previous findings on MOTS-c metrics including MOTS-c levels decreasing with age. However, there are few clinical trials evaluating MOTS-c in cancer survivors. MOTS-c is a potential biomarker related to exercise in cancer survivors. Our study was predominantly conducted in Asian women where there is limited data. This emphasizes the need for more clinical trials to be conducted with racially/ethnically diverse populations to better understand MOTS-c’s role in our varied cancer populations.

Abstract
Abstract
Background: Previous studies have demonstrated that breast cancer survivors commonly experience a decrease in quality of life including an increased risk of depression, insomnia, cancer-related fatigue, and negative body image. Several studies have shown that exercise interventions, such as yoga, Pilates, water aerobics, and strengthening exercises, can improve survivors’ quality of life. We implemented a 12-week exercise program in breast cancer survivors and evaluated body composition and quality of life changes. Here we discuss our findings evaluating 5 quality of life questionnaires.
Methods: We evaluated 22 participants who completed a baseline and post 12-week questionnaire assessments. All participants underwent a 12-week exercise program 3 times/week for 90 minutes/session. We calculated differences in baseline and post 12-week quality of life through 5 questionnaires: Functional Assessment of Cancer Therapy - General (FACT-G), Social Support, Insomnia Severity Index, Brief Fatigue Inventory, and Body Image after Breast Cancer (BIBCQ) and assessed the intervention’s efficacy by comparing the baseline and post 12-week scores using paired t-tests.
Results: The difference between baseline and post 12-week quality of life are presented in Table 1. 7/13 questionnaires showed statistical significance: FACT-G Emotional, FACT-G Functional, Insomnia Severity Index, BIBCQ Vulnerability Scale (VS), BIBCQ Body Stigma Scale (BSS), BIBCQ Limitation Scale (LS), and BIBCQ Body Concern Scale (BCS). Interestingly, 4/6 of the BIBCQ questionnaires showed statistical significance: BIBCQ VS, BIBCQ BSS, BIBCQ LS, and BIBCQ BCS.
Summary: Our study showed improvement in all metrics evaluated in breast cancer survivors who underwent the personalized exercise program. Specifically, multiple questionnaires including body image were improved with exercise which further exemplifies the impact of lifestyle changes on quality of life measures and is an important adjunct to future cancer survivorship studies.

Abstract
Planetary rings are observed not only around giant planets1, but also around small bodies such as the Centaur Chariklo2 and the dwarf planet Haumea3. Up to now, all known dense rings were located close enough to their parent bodies, being inside the Roche limit, where tidal forces prevent material with reasonable densities from aggregating into a satellite. Here we report observations of an inhomogeneous ring around the trans-Neptunian body (50000) Quaoar. This trans-Neptunian object has an estimated radius4 of 555 km and possesses a roughly 80-km satellite5 (Weywot) that orbits at 24 Quaoar radii6,7. The detected ring orbits at 7.4 radii from the central body, which is well outside Quaoar's classical Roche limit, thus indicating that this limit does not always determine where ring material can survive. Our local collisional simulations show that elastic collisions, based on laboratory experiments8, can maintain a ring far away from the body. Moreover, Quaoar's ring orbits close to the 1/3 spin-orbit resonance9 with Quaoar, a property shared by Chariklo's2,10,11 and Haumea's3 rings, suggesting that this resonance plays a key role in ring confinement for small bodies.

Abstract
BAP1 is a powerful tumor suppressor gene characterized by haplo insufficiency. Individuals carrying germline BAP1 mutations often develop mesothelioma, an aggressive malignancy of the serosal layers covering the lungs, pericardium, and abdominal cavity. Intriguingly, mesotheliomas developing in carriers of germline BAP1 mutations are less aggressive, and these patients have significantly improved survival. We investigated the apparent paradox of a tumor suppressor gene that, when mutated, causes less aggressive mesotheliomas. We discovered that mesothelioma biopsies with biallelic BAP1 mutations showed loss of nuclear HIF-1α staining. We demonstrated that during hypoxia, BAP1 binds, deubiquitylates, and stabilizes HIF-1α, the master regulator of the hypoxia response and tumor cell invasion. Moreover, primary cells from individuals carrying germline BAP1 mutations and primary cells in which BAP1 was silenced using siRNA had reduced HIF-1α protein levels in hypoxia. Computational modeling and co-immunoprecipitation experiments revealed that mutations of BAP1 residues I675, F678, I679, and L691 -encompassing the C-terminal domain-nuclear localization signal- to A, abolished the interaction with HIF-1α. We found that BAP1 binds to the N-terminal region of HIF-1α, where HIF-1α binds DNA and dimerizes with HIF-1β forming the heterodimeric transactivating complex HIF. Our data identify BAP1 as a key positive regulator of HIF-1α in hypoxia. We propose that the significant reduction of HIF-1α activity in mesothelioma cells carrying biallelic BAP1 mutations, accompanied by the significant reduction of HIF-1α activity in hypoxic tissues containing germline BAP1 mutations, contributes to the reduced aggressiveness and improved survival of mesotheliomas developing in carriers of germline BAP1 mutations.

Abstract
PURPOSE Tumor-infiltrating lymphocytes (TILs) have emerged as a predictor of breast cancer treatment response and patient outcomes. Current studies investigating racial/ethnic differences in TILs and immune profiles in breast cancer offer varying results. Our study provides some preliminary data in the breast cancer tumor microenvironment where there is a paucity of information, from Asian and Native Hawaiian/Pacific Islander (NHPI) racial/ethnic groups, not well represented in the literature. METHODS We reviewed 183 cases of women diagnosed with early stage breast cancer who received neoadjuvant treatment at 2 large health systems in Hawaii between 2008 and 2020. We evaluated clinical and demographic information including: age at diagnosis, self-reported race/ethnicity, tumor stage, tumor subtype according to ER, PR, and HER2 receptor status, the amount of TILs and pathologic complete response (pCR). RESULTS We found a significantly greater amount of TILs in Asians (37.7%, P = .01) and NHPI (37.2%, P = .02) patients compared to White patients on multivariate analysis. We found no significant differences in pCR among the different racial/ethnic groups. CONCLUSIONS Racial/ethnic differences in the amount of TILs in breast cancer tumors may suggest differences in the breast tumor microenvironment. This may in part contribute to known outcome disparities in these populations and should be further evaluated.

Abstract
INTRODUCTION Breast cancer is the most prevalent cancer and the second leading cause of cancer death among women in the United States. Liquid biopsy is becoming a more commonly accepted method in clinical practice. Thus, there is a need to investigate ways to utilize circulating-tumor DNA (ctDNA) in metastatic breast cancer (mBC). The primary objective of this study was to characterize the genomic landscape of ctDNA in a diverse patient population and across different subtypes of mBC. METHODS We analyzed the ctDNA profile in patients (n = 45) with mBC who received a Guardant360 liquid biopsy test. Patient demographics, age at diagnosis, race, subtype, and mutations were included in the analysis. RESULTS The majority of patients (n = 39, 86.7%) had at least one gene alteration detected in their liquid biopsy. We found no statistically significant differences in genomic landscape according to race. However, there were differences seen in tumor genomics according to age and subtype. Postmenopausal patients were more likely to have detectable disease on liquid biopsy compared to premenopausal patients (p = 0.001). Mutations in ESR1 (n = 10) and PIK3CA (n = 8) were more commonly seen in hormone positive (HR+) mBC, where known tailored treatment options are available (i.e., fulvestrant and alpelisib respectively). The most common alterations detected include TP53 (n = 22) followed by PIK3CA (n = 15), ESR1 (n = 11), CCND1 (n = 7), and ERBB2 (n = 7). CONCLUSION Liquid biopsies are effective tools that can reveal clinically relevant information including mutational status and therapeutic options.

Abstract
BACKGROUND Telehealth visits increase patients' access to care and are often rated as "just as good" as face-to-face visits by oncology patients. Telehealth visits have become increasingly more common in the care of patients with cancer since the advent of the COVID-19 pandemic. Asians and Pacific Islanders are two of the fastest growing racial groups in the United States, but there are few studies assessing patient satisfaction with telemedicine among these two racial groups. OBJECTIVE Our objective was to compare satisfaction with communication during telehealth visits versus face-to-face visits among oncology patients, with a specific focus on Asian patients and Native Hawaiian and other Pacific Islander (NHOPI) patients. METHODS We surveyed a racially diverse group of patients who were treated at community cancer centers in Hawaii and had recently experienced a face-to-face visit or telehealth visit. Questions for assessing satisfaction with patient-physician communication were adapted from a previously published study of cancer survivors. Variables that impact communication, including age, sex, household income, education level, and cancer type and stage, were captured. Multivariable logistic models for patient satisfaction were created, with adjustments for sociodemographic factors. RESULTS Participants who attended a face-to-face visit reported higher levels of satisfaction in all communication measures than those reported by participants who underwent a telehealth encounter. The univariate analysis revealed lower levels of satisfaction during telehealth visits among Asian participants and NHOPI participants compared to those among White participants for all measures of communication (eg, when asked to what degree "[y]our physician listened carefully to you"). Asian patients and NHOPI patients were significantly less likely than White patients to strongly agree with the statement (P<.004 and P<.007, respectively). Racial differences in satisfaction with communication persisted in the multivariate analysis even after adjusting for sociodemographic factors. There were no significant racial differences in communication during face-to-face visits. CONCLUSIONS Asian patients and NHOPI patients were significantly less content with patient-physician communication during telehealth visits when compared to White patients. This difference among racial groups was not seen in face-to-face visits. The observation that telehealth increases racial disparities in health care satisfaction should prompt further exploration.

Abstract
BACKGROUND Health literacy encompasses various levels of communication for an individual, provider, and an organization. Validated and reliable tools have been developed to assess health literacy; however, there is a paucity of tools available to assess health literacy in native languages for indigenous and racial/ethnic minority populations. OBJECTIVE This article shares the process taken to translate and evaluate validation and reliability of the Short Test of Functional Health Literacy in Adults for use with the Samoan population. METHODS Respondent-driven sampling was used to collect data from 1,543 adults age 45 years and older in American Samoa. A confirmatory factor analysis using a two-factor model for validation was conducted. KEY RESULTS The validation results indicated a "good fit" in multiple indices and Cronbach's alpha indicated high internal consistency in both the English and Samoan languages. CONCLUSIONS Developing culturally validated and reliable health literacy assessment tools is important to help health care professionals decrease health disparities and address inadequate health literacy in all cultures. [HLRP: Health Literacy Research and Practice. 2022;6(4):e247-e256.] Plain Language Summary: The INSPIRE project studied the Short Test of Functional Health Literacy in Adults (STOFHLA) tested on the American Samoan population age 50 years and older. The results would show if the STOFHLA is a valid tool to measure functional health literacy in American Samoa adults.

Abstract
Objectives: To examine the feasibility, acceptability, and preliminary efficacy of Mindfulness Coach, an mHealth Mindfulness Therapy intervention.Methods: We recruited 58 informal caregivers of older adults with cognitive impairment for this pilot feasibility trial. Participants completed measures of caregiver burden, stress, anxiety, and depression at baseline, 2 weeks, 4 weeks, and 8 weeks as well as acceptability and usability data at 8-weeks. The mobile app collected in-app use data including minutes spent using the app and number of unique visits to the app.Results: Users found the app acceptable to use and were satisfied with its design and usability. Over the course of the study period, depression, anxiety, caregiver burden and perceived stress improved. These outcome variables also improved more as caregivers spent more time using the Mindfulness Therapy mHealth intervention.Conclusions: Our results suggest that mHealth mindfulness therapy with caregivers of older adults with cognitive impairment is both feasible and acceptable to users, and that it successfully reduces psychological symptoms. Future work should focus on determining the appropriate doses of the mHealth therapy for particular outcomes and strategies to integrate it into routine care. Mindfulness Therapy delivered in an mHealth format may increase access to psychological treatment for caregivers.

Abstract
Associations of e-cigarette use with respiratory disorder have been demonstrated but it has been unclear whether these are confounded by current or previous cigarette smoking. We address this question through studying different time frames for e-cigarette use and respiratory disorders in 2020 BRFSS data (N = 214,945). E-cigarette use and combustible cigarette smoking were classified into four categories: Participant never used either (Nonuse); used e-cigarettes/cigarettes but not in the past 30 days (Former Use), used in past 30 days on some days (Nondaily Use), or used past 30 days on all days (Daily Use). Contrasts for e-cigarette status and cigarette status (with nonuse as reference group) were entered with covariates in logistic regression with asthma or COPD as criterion. Stratified analyses of e-cigarette use were also performed for smokers and nonsmokers. In the total sample, results showed independent positive associations with both lifetime and current asthma for Former, Nondaily, and Daily e-cigarette use (mostly p < .0001) and the three cigarette indices. Significant positive associations with COPD were found for the three e-cigarette indices (p < .0001) and all the cigarette indices. Stratified analyses showed significant associations of e-cigarette use with respiratory disorder among nonsmokers as well as among smokers. We conclude that independent associations for former e-cigarette use (controlling for current/former smoking) and significant associations of e-cigarette use with respiratory disorder among nonsmokers indicate these associations are not confounded with cigarette smoking and suggest reverse causation is implausible. Findings for former use are discussed with reference to possible mechanisms including sensitization effects.

Abstract
Bladder cancer is a biologically heterogeneous disease with variable clinical presentations, outcomes and responses to therapy. Thus, the clinical utility of single biomarkers for the detection and prediction of biological behavior of bladder cancer is limited. We have previously identified and validated a bladder cancer diagnostic signature composed of 10 biomarkers, which has been incorporated into a multiplex immunoassay bladder cancer test, Oncuria™. In this study, we evaluate whether these 10 biomarkers can assist in the prediction of bladder cancer clinical outcomes. Tumor gene expression and patient survival data from bladder cancer cases from The Cancer Genome Atlas (TCGA) were analyzed. Alignment between the mRNA expression of 10 biomarkers and the TCGA 2017 subtype classification was assessed. Kaplan-Meier analysis of multiple gene expression datasets indicated that high expression of the combined 10 biomarkers correlated with a significant reduction in overall survival. The analysis of three independent, publicly available gene expression datasets confirmed that multiplex prognostic models outperformed single biomarkers. In total, 8 of the 10 biomarkers from the Oncuria™ test were significantly associated with either luminal or basal molecular subtypes, and thus, the test has the potential to assist in the prediction of clinical outcome.

Abstract
PURPOSE Although effective care coordination (CC) is recognized as a vital component of a patient-centered, high-quality cancer care delivery system, CC experiences of patients who enroll and receive treatment through clinical trials (CTs) are relatively unknown. Using mixed methods, we examined perceptions of CC among patients enrolled onto therapeutic CTs through the Hawaii Minority/Underserved National Cancer Institute Community Oncology Research Program. METHODS The Care Coordination Instrument, a validated instrument, was used to measure patients' perceptions of CC among CT participants (n = 45) and matched controls (n = 45). Paired t-tests were used to compare overall and three CC domain scores (Communication, Navigation, and Operational) between the groups. Semistructured focus group interviews were conducted virtually with 14 CT participants in 2020/2021. RESULTS CT participants reported significantly higher total CC scores than non-CT participants (P = .0008). Similar trends were found for Navigation and Operational domain scores (P = .007 and .001, respectively). Twenty-nine percent of CT participants reported receiving high-intensity CC assistance from their clinical research professionals (CRPs). Content analysis of focus group discussions revealed that nearly half of the focus group discussions centered on CRPs (47%), including CC support provided by CRPs (26%). Other key themes included general CT experiences (22%) and CRP involvement as an additional benefit to CT participation (15%). CONCLUSION Our results show that patients on CTs in this study had a more positive CC experience. This may be attributable in part to CC support provided by CRPs. These findings highlight both the improved experience of treatment for patients participating in a trial and the generally unrecognized yet integral role of CRPs as part of a cancer CT care team.

Abstract
AIM To test whether intrapersonal growth in e-cigarette advertising exposure over time is associated with growth in e-cigarette use and/or cigarette smoking. DESIGN Longitudinal study using four waves of data were collected in 6-month intervals between 2018 and 2020. SETTING AND PARTICIPANTS Participants were 2327 young adults recruited from colleges in Hawaii, USA. MEASUREMENTS Data were collected on demographics, e-cigarette advertising exposure measured using the cued- recall method and recent (past 30-day) cigarette and e-cigarette use. FINDINGS The average trajectory for e-cigarette advertising exposure over time was significant and upward [M slope = 0.18 (0.14-0.22), P < 0.0001]. However, average trajectories for e-cigarette [M slope = -0.08 (-0.18 to 0.02), P = 0.09] and cigarette [M slope = -0.14 (-0.30 to 0.02), P = 0.07] use were not. There were significant differences in individual level trajectories across participants for advertising exposure [σ2 = 0.12 (0.10-0.14), P < 0.0001], e-cigarette use [σ2 = 0.22 (0.14-0.30), and cigarette smoking (σ2 = 0.17 [0.09-0.25], P < 0.0001). Individuals with an increasing rate of advertising exposure showed an increasing rate of e-cigarette use [B = 0.63 (0.36-0.90), P < 0.0001). Neither initial level of, nor rate of change in, advertising exposure was significantly associated with cigarette smoking growth factors (P > 0.05). Higher initial level of e-cigarette use was associated with higher initial level of cigarette smoking [B = 0.89 (0.69-1.09), P < 0.0001] but decreased rate of cigarette smoking over time [B = -0.12 (-0.20 to -0.04) P = 0.003]. Rate of change in e-cigarette use was not associated with the rate of change in cigarette smoking (P > 0.05). CONCLUSIONS Increased exposure to e-cigarette advertising appears to be associated with increased e-cigarette use but not with increased cigarette smoking. Higher initial level of e-cigarette use appears to be associated with higher initial level of cigarette smoking but may be associated with a decreasing rate of cigarette smoking over time.

Abstract
Oncuria™ is a validated quantitative multiplex immunoassay capable of detecting bladder cancer from a voided urine sample. Herein, we sought to determine whether Oncuria™ affects physicians' use of non-invasive and invasive diagnostic tests for microhematuria, gross hematuria, and bladder cancer surveillance. We conducted a survey-based study to assess physician management of nine clinical scenarios involving real-world data from patients with gross hematuria, microhematuria, and bladder cancer on surveillance. We randomly sampled 15 practicing urologists and generated data including 135 patient-by-urologist interactions and 2160 decision points. Urologists recommended a selection of diagnostic tests and procedures before and after Oncuria™ results were provided. We assessed changes in provider use of non-invasive and invasive diagnostic tests after Oncuria™ results were provided. Over 90% of all urologists changed their diagnostic behavior in at least one patient case with the addition of Oncuria™ results. The total number of diagnostic procedures was reduced by 31% following the disclosure of a negative Oncuria™ test and 27% following the disclosure of a positive Oncuria™ test. This is pilot study has the potential to shed light on the analysis of our four large multicenter international studies deploying OncuriaTM. The Oncuria™ urine-based test, a molecular diagnostic capable of ruling out the presence of bladder cancer, reduces both unnecessary invasive and non-invasive diagnostics and has the potential to reduce costs and improve patient outcomes.

Abstract
BACKGROUND Intravesical Bacillus Calmette-Guerin (BCG), a live attenuated tuberculosis vaccine that acts as a non-specific immune system stimulant, is the most effective adjuvant treatment for patients with intermediate or high-risk non-muscle-invasive bladder cancer (NMIBC). However, to date, there are no reliable tests that are predictive of BCG treatment response. In this study, we evaluated the performance of OncuriaTM, a bladder cancer detection test, to predict response to intravesical BCG. METHODS OncuriaTM data was evaluated in voided urine samples obtained from a prospectively collected cohort of 64 subjects with intermediate or high risk NMIBC prior to treatment with intravesical BCG. The OncuriaTM test, which measures 10 cancer-associated biomarkers was performed in an independent clinical laboratory. The ability of the test to identify those patients in whom BCG is ineffective against tumor recurrence was tested. Predictive models were derived using supervised learning and cross-validation analyses. Model performance was assessed using ROC curves. RESULTS Pre-treatment urinary concentrations of MMP9, VEGFA, CA9, SDC1, PAI1, APOE, A1AT, ANG and MMP10 were increased in patients who developed disease recurrence. A combinatorial predictive model of treatment outcome achieved an AUROC 0.89 [95% CI: 0.80-0.99], outperforming any single biomarker, with a test sensitivity of 81.8% and a specificity of 84.9%. Hazard ratio analysis revealed that patients with higher urinary levels of ANG, CA9 and MMP10 had a significantly higher risk of disease recurrence. CONCLUSIONS Monitoring the urinary levels of a cancer-associated biomarker panel enabled the discrimination of patients who did not respond to intravesical BCG therapy. With further study, the multiplex OncuriaTM test may be applicable for the clinical evaluation of bladder cancer patients considering intravesical BCG treatment.

Abstract
Exposure to e-cigarette content on social media may affect behavior in the real-time. Exposure to anti-e-cigarette content may have a lagged effect on behavior. Exposure to pro-e-cigarette content may have a more immediate effect on behavior.
This pilot ecological momentary assessment (EMA) study tested the associations between exposure to anti-e-cigarette content on social media and e-cigarette use behavior. For exposure to anti-e-cigarette posts, participants were asked to follow the study account on Instagram, on which anti-e-cigarette content were posted regularly. In addition, we assessed participants’ exposure to pro-e-cigarette content in their daily lives and examined the effects of such exposure on behavior. Participants were 29 diverse young adult current e-cigarette users (18–30 year olds; 54% women), who provided data 3 times daily, for 3 weeks via a mobile phone based EMA application. Relative to no exposure, exposure to anti-e-cigarette content was associated with decreased recent e-cigarette use frequency at the next assessment time-point (p < 0.05; 2-tailed). In addition, a statistically significant concurrent association was found between exposure to pro-e-cigarette content (relative to no exposure) and higher e-cigarette use (p < 0.05; 2-tailed). The current data are some of the first to show that exposure to anti-e-cigarette content on social media may have real time effects on decreased e-cigarette use among young adults as they go about their daily lives. Policies and efforts designed to regulate pro-e-cigarette and promote anti-e-cigarette content on social media may help reduce e-cigarette use among young people.

Abstract
OBJECTIVE The aim of this study was to investigate whether digitally re-posing three-dimensional optical (3DO) whole-body scans to a standardized pose would improve body composition accuracy and precision regardless of the initial pose. METHODS Healthy adults (n = 540), stratified by sex, BMI, and age, completed whole-body 3DO and dual-energy X-ray absorptiometry (DXA) scans in the Shape Up! Adults study. The 3DO mesh vertices were represented with standardized templates and a low-dimensional space by principal component analysis (stratified by sex). The total sample was split into a training (80%) and test (20%) set for both males and females. Stepwise linear regression was used to build prediction models for body composition and anthropometry outputs using 3DO principal components (PCs). RESULTS The analysis included 472 participants after exclusions. After re-posing, three PCs described 95% of the shape variance in the male and female training sets. 3DO body composition accuracy compared with DXA was as follows: fat mass R2 = 0.91 male, 0.94 female; fat-free mass R2 = 0.95 male, 0.92 female; visceral fat mass R2 = 0.77 male, 0.79 female. CONCLUSIONS Re-posed 3DO body shape PCs produced more accurate and precise body composition models that may be used in clinical or nonclinical settings when DXA is unavailable or when frequent ionizing radiation exposure is unwanted.

Abstract
109 Background: The COVID-19 pandemic has disrupted medical care in all areas of the US and had a profound impact on cancer screening, with a concern that this may lead to excess cancer-related deaths over the next decade. There are existing disparities in cancer mortality among rural US residents and Native Hawaiians (NHs) due to access issues, lower socioeconomic status and lack of a sufficient provider workforce. A reduction in cancer screening may therefore have an oversized impact on these populations. In this study, we examine the effects of the COVID-19 pandemic on cancer screening frequency among NHs and in urban and rural populations in Hawaii. Methods: De-identified data on the frequencies of breast cancer (BCS), cervical cancer (CCS) and colorectal cancer (CRCS) screenings for 2019 and 2020 were obtained for Hawaii residents from several sources, including Hawaii Medical Services Association, the largest private and Medicaid provider in Hawaii, and the two largest state-wide health systems, Queen’s Health Systems and Hawaii Pacific Health. Data was analyzed using Rural-Urban Continuum Codes (RUCC) and Rural-Urban Commuting Area (RUCA) codes to define rurality and, along with health system facility location, to ascertain whether there was a differential impact on cancer screening rates for rural populations due to the pandemic. Cancer screening data for NHs in comparison to other groups was analyzed separately. Results: Overall, reductions in cancer screening during the pandemic were seen, with the degree of reduction varying widely across regions of the state and among different ethnic populations. Annual reductions in BCS, CCS and CRCS ranged from 4.0-30.2%, 2.7-3.0% and 9.4-13.2%, respectively, depending on the data source. BCS reductions were greatest in rural areas (p = 0.09) and among NHs (p = 0.0005). The island of Kauai, which is rural but was minimally affected by COVID-19, saw no reduction in BCS. CCS reductions had a reverse urban vs. rural pattern, with reductions of 4.5% urban and 0.8% rural (p = 0.02). CRCS reductions were most profound in rural residents (17.1%; p = 0.0001); reductions in CRCS among NHs were 1.5x greater than other groups. The differential impact across urban and rural areas was consistent for both RUCC and RUCA analysis. The extent of reduction was most significant for CRCS and was directly proportional to the degree of rurality. Conclusions: BCS and CRCS were impacted more significantly by the COVID-19 pandemic than CCS. For BCS and CRCS, greater reductions were seen in rural compaed to urban populations and in NHs. The lack of correlation with rurality for CCS may be because this population is generally younger and screening is often provided as a component of primary care. The greater pandemic-related reduction in screening among rural residents and Native Hawaiians may exacerbate existing cancer mortality disparities in these vulnerable populations.

Abstract
OBJECTIVE Subgroups of adolescent single and dual e-cigarette and cigarette users have been identified, but usage patterns have changed in recent years, and there has been an increase in marijuana use. Research is needed with current data to identify subgroups of use including marijuana and determine their behavioral correlates. METHODS We cross classified ever and recent use of e-cigarettes, combustible cigarettes, and marijuana among US high school students in the 2019 Youth Risk Behavior Survey (YRBS), providing 8 different groups. Levels of 14 risk and protective factors were compared across groups in general linear models with demographic covariates using omnibus tests, pairwise comparisons, and planned contrasts. Replicability was tested through identical analyses for 2017 YRBS data. RESULTS The nonuser group was 43.9% of the sample. The most frequent user groups were triple users (ever-use proportion: 16.9%), dual (e-cigarette and marijuana) users (15.8%), and exclusive e-cigarette users (13.2%). For risk profiles on levels of psychosocial variables, the triple-user group was typically elevated above all other groups. Exclusive e-cigarette users were above nonusers in risk profile but below dual users (both cigarettes and marijuana). Results were similar for ever use and recent use. The patterning of results in 2019 YRBS data were closely replicated in 2017 YRBS data. CONCLUSIONS Co-occurrence of e-cigarette, cigarette, and marijuana use is currently substantial among adolescents and is associated with an elevated psychosocial risk profile. This has implications for both epidemiology and prevention studies. Further research is needed to study prevalence and identify pathways to triple use.

Abstract
168 Background: According to the Institute of Medicine, care coordination (CC) is a critical component of high-quality cancer care; however, many patients with cancer continue to experience fragmented care. CC experiences among cancer clinical trial (CT) participants are relatively unknown. Using mixed methods, we examined perceptions of CC among patients enrolled on therapeutic CTs conducted through the Hawaii Minority/Underserved NCI Community Oncology Research Program (NCORP). Methods: Forty-five CT participants completed the validated Care Coordination Instrument (CCI). The CCI assesses cancer patients’ perceptions of CC overall and across Communication, Navigation, and Operational domains. Data from 45 non-CT participants matched by age, gender, cancer type (breast, GI, other), and clinical stage from our prior studies served as a control group. Paired t-tests were used to compare the CCI scores between the two groups. Three semi-structured focus group interviews were conducted with 14 CT participants in 2020 and 2021. Results: The mean age of CT participants was 61.7 ( SD = 9.4), with the majority being female (67%) and Asian (56%). The most common cancer disease sites were breast (27%) and GI (16%). CT participants reported significantly higher total CC scores than non-participants ( p =.0008). Similar trends were found for Navigation ( p =.007) and Operational ( p =.001) domain scores. 56% of CT participants reported receiving moderate to high-intensity CC assistance from their clinical research professionals (CRPs). Content analysis of focus group discussions revealed that the majority of CT participants’ comments aligned with CC domains; 42% Communication, 30% Navigation, and 28% Operational. Nearly half of focus group discussions centered on CRPs (47%), including CC support provided by CRPs (26%). Other key themes that emerged from the focus groups included general CT experiences (22%) and CRP involvement as an additional benefit to CT participation (15%). Conclusions: Clinical trial participants perceive better CC than non-CT participants, partly attributed to CC support provided by CRPs. Our findings highlight a generally unrecognized yet integral role of CRPs as part of a cancer clinical trial care team. CRP involvement may be an additional benefit of CT participation and contribute to improved quality and value for patient-centered cancer care.

Abstract
The optimal treatment strategy for patients with early prostate cancer (PCa) is unknown. We explored the feasibility of administering noni supplementation to modify gene expression of a relevant clinical signature in the prostate of men on active surveillance for PCa. A total of 6 participants with low-risk (n=5) to very low-risk (n=1) PCa who were candidates for active surveillance received 6200 mg/day of noni in capsule form for 1 year; median age was 65.5 years (range, 58-75 years). Participants were tested for serum prostate-specific antigen (PSA) levels every 3 months. At 12 months, they underwent a repeat transrectal ultrasound-guided prostate biopsy. These biopsy samples were queried for expressing 12 key genes and rates of apoptosis, angiogenesis, and proliferation. The primary outcome was the change in expression of the 12 genes that comprise the Oncotype DX prostate cancer test from baseline to 12 months of noni supplementation. Noni was well tolerated, with only 1 participant reporting side effects of grade 2 diarrhea, requiring a drug holiday of 7 days. Median serum PSA slightly increased from 7.1 ng/mL (4.4-9.7 ng/ mL) prior to therapy to 7.9 ng/mL (5.7-10.2 ng/mL) on therapy. Changes were observed in the expression levels of several genes, including FAM13C, KLK2 (associated with the androgen pathway), and GSTM2 (associated with cellular organization) at 12 months. Noni supplementation was associated with favorable clinical parameters, including stable serum PSA among most patients and no evidence of tumor on repeat biopsy, and correlated with modulation of numerous genes and proteins.

Abstract
Background Combining an immune checkpoint inhibitor with a tumor vaccine may modulate the immune system to leverage complementary mechanisms of action that lead to sustained T-cell activation and a potent prolonged immunotherapeutic response in metastatic castration resistant prostate cancer (mCRPC). Methods Subjects with asymptomatic or minimally symptomatic mCRPC were randomly assigned in a 1:1 ratio to receive either atezolizumab followed by sipuleucel-T (Arm 1) or sipuleucel-T followed by atezolizumab (Arm 2). The primary endpoint was safety, while secondary endpoints included preliminary clinical activity such as objective tumor response and systemic immune responses that could identify key molecular and immunological changes associated with sequential administration of atezolizumab and sipuleucel-T. Results A total of 37 subjects were enrolled. The median age was 75.0 years, median prostate specific antigen (PSA) was 21.9 ng/mL, and subjects had a median number of three prior treatments. Most subjects (83.8%) had at least one treatment-related adverse event. There were no grade 4 or 5 toxicities attributed to either study drug. Immune-related adverse events and infusion reactions occurred in 13.5% of subjects, and all of which were grade 1 or 2. Of 23 subjects with Response Evaluation Criteria in Solid Tumors measurable disease, only one subject in Arm 2 had a partial response (PR) and four subjects overall had stable disease (SD) at 6 months reflecting an objective response rate of 4.3% and a disease control rate of 21.7%. T-cell receptor diversity was higher in subjects with a response, including SD. Immune response to three novel putative antigens (SIK3, KDM1A/LSD1, and PIK3R6) appeared to increase with treatment. Conclusions Overall, regardless of the order in which they were administered, the combination of atezolizumab with sipuleucel-T appears to be safe and well tolerated with a comparable safety profile to each agent administered as monotherapy. Correlative immune studies may suggest the combination to be beneficial; however, further studies are needed. Trial registration number NCT03024216.

Abstract
Aim: To assess the perception of telehealth visits among a multiracial cancer population during the coronavirus disease 2019 pandemic. Methods: This cross-sectional study was conducted at outpatient cancer clinics in Hawaii between March and August 2020. Patients were invited to participate in the survey either by phone or email. Results: Of the 212 survey respondents, 61.3% were Asian, 23.6% were White and 15.1% were Native Hawaiians or Pacific Islanders. Asians, Native Hawaiians and Pacific Islanders were less likely to desire future telehealth visits compared with Whites. Predictors with regard to preferring future telehealth visits included lower income and hematopoietic cancers. Conclusion: The authors found racial differences in preference for telehealth. Future studies aimed at overcoming these racial disparities are needed to provide equitable oncology care.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the few cancers that can be diagnosed based on imaging findings alone. The factors associated with the decision to perform a biopsy and the clinical impact have not been previously studied. METHODS We collected data of patients diagnosed with HCC between 2004 and 2015 from the National Cancer Database. We assessed associations between biopsy and survival with demographic and clinical factors. RESULTS We included 160,507 patients. The median age was 62 (40-90), 74.1% were male and 74.9% were white. Over the 12-year period, 47.7% (76,524/160,517) underwent a biopsy. Factors associated with a biopsy were black race, older age, presence of metastatic disease, larger tumor size, and treatment at a community cancer center. Factors associated with increased mortality were older age, higher comorbidity index, larger tumor size, presence of metastatic disease, higher AFP and elevated bilirubin. There was a significant decreased use of biopsy over successive years (2007-2015). After adjusting for prognostic factors, biopsy had no significant impact on survival HR 1.01 (95%CI 1.00-1.03. p = 0.07). CONCLUSIONS A significant number of patients underwent a biopsy. Performing a biopsy did not have a significant impact on survival.

BACKGROUND Breast cancer is the most common cancer in women, and postoperative breast pain has been reported to be anywhere from 25% to 60%. However, there is sparse data regarding racial/ethnic differences in breast pain among breast cancer patients. METHODS We performed a cross-sectional anonymous survey of breast cancer patients from the Hawaii Cancer Consortium over a 6-week period between 2019 and 2020. The 237 breast cancer participants were ages 29 to 98, 74% Asian, and mainly from outpatient oncology clinics. We evaluated the prevalence of breast pain in a diverse group of breast cancer patients and characterized the pain using a modified short-form McGill pain questionnaire (sfMPQ). RESULTS Eighty-fourrespondents(35.4%) reported breast pain. On univariable analysis, we found significant racial/ethnic differences in the amount of breast pain, where Chinese and Japanese participants reported significantly less pain compared to White participants on a 10-point pain scale. We found differences in breast pain according to age and endocrine therapy use as well as survey location, however, no differences were seen according to chemotherapy, radiation, or breast surgery. Based on the sfMPQ, the most common descriptors of breast pain were sensory (throbbing, shooting, and stabbing) compared to affective (tiring-exhausting, sickening, fearful, and punishing-cruel) characteristics. Although they were described as mild and intermittent, in women with breast pain, 33.4% reported the breast pain affected their sleep, 16.7% their work, and 15.4% their sexual activity. CONCLUSIONS Breast pain is a significant problem in our breast cancer community. This survey assessment has informed our understanding of breast pain in our diverse population. In turn, we are developing culturally appropriate pain management strategies to treat this challenging symptom common in breast cancer survivors.

Abstract
e12512 Background: Breast cancer incidence and mortality rate differ across racial/ethnic populations in the US, but little is known about the relationship between Oncotype DX scores and race/ethnicity. Oncotype DX scores are used in early stage, hormone positive breast cancers to estimate the likelihood of breast cancer recurrence and benefit from receiving chemotherapy. Most available literature assesses disparities between race and receipt of an Oncotype DX score, with only some assessing distribution of scores by race. Populations previously studied mainly focus on Black compared to White women, with very few including Asian and Native Hawaiian/Pacific Islander subpopulations. When included, they are often grouped together as Asian/Pacific Islander. Current studies suggest there is a similar distribution of scores among Black and White women, but some studies report that Black women may be more likely to have high-risk scores. Methods: We examined 476 unique breast cancer cases in the Hawaii Pacific Health system diagnosed in 2018-2020. We used univariable and multivariable analyses on all of those cases that received an Oncotype DX score to determine correlation to age and race. Results: In 328 breast cancer cases that received an Oncotype DX score, age of diagnosis ranged from 29 to 84 with race/ethnicity including Japanese (n = 90, 27%), White (n = 78, 24%), Filipino (n = 54, 17%), Native Hawaiian (n = 52, 16%), Chinese (n = 24, 7%), and other (n = 30, 9%) populations. Cases with age at diagnosis between 60-69 (n = 118, 36%) were found to have a mean Oncotype DX score of 13.91 (CI 12.19-15.62, p = 0.04) which was statistically lower than other ages groups on both univariable and multivariable analysis. We found no other significant relationships between Oncotype DX score and race or age at diagnosis on our analyses. Conclusions: These findings contribute more information about Oncotype DX scores within Asian and Native Hawaiian populations to the available literature.

Abstract
e13066 Background: Breast cancer is the most prevalent cancer and the second leading cause of cancer deaths among women in the United States. Once the primary breast cancer has metastasized to other parts of the body, despite treatment, patients have an incurable disease. Compared to the primary tumor, often the metastasized tumor sites have different mutational profiles that are not represented in the initial biopsy. Liquid biopsy is becoming a more commonly accepted method in clinical practice to determine the heterogeneity of metastatic tumors by analyzing cell-free DNA (cfDNA). Several studies have demonstrated that cfDNA can be utilized as an effective prognostic tool and can reveal multiple clinically targetable alterations in metastatic breast cancer (mBC). Methods: We characterized the genomic landscape of cfDNA in a diverse patient population and across different subtypes of mBC. We performed a retrospective chart review in patients (n = 41) with metastatic breast cancer from a medical oncology clinic within the Hawaii Pacific Health system. Patients who had at least one cfDNA testing by Guardant360 were evaluated. Patient demographics, age at diagnosis, race, subtype and mutations were reviewed along with treatment information. Results: We found no statistically significant differences in genomic landscape according to race, however there were differences seen in tumor genomics according to age and subtype. Older patients were less likely to have detectable disease on liquid biopsy compared to younger patients (age 70+ and 60-69 vs 30-39; xp 0.02). Consistent with subtype, mutations in ESR1 (n = 12) and PIK3CA (n = 14) were more commonly seen in hormone positive (HR+) mBC where known tailored treatment options are available (ie. fulvestrant and alpelisib respectively). Postmenopausal patients were more likely to have ESR1 mutations than premenopausal patients (50-59 and 70+ vs 30-39 and 40-49, xp 0.009). About half (n = 20) had TP53 mutations, followed by PIK3CA (n = 14), ESR1 (n = 12), CCND1 (n = 7) and MYC (n = 6). Conclusions: We evaluated 41 unique cases of mBC and correlated them with their genomic profiles. We plan to further investigate genomic changes according to treatment with subsequent repeat liquid biopsies. We hope to utilize these findings to help prognosticate and guide future treatment options.

Abstract
e13504 Background: Effective coordination of care (CC) is a critical component of high-quality cancer care; however, many patients with cancer continue to receive poorly coordinated care. CC experiences among therapeutic clinical trial (CT) participants are relatively unknown. We examined cancer patients’ perceptions of CC among CT participants using a validated Care Coordination Instrument (CCI). Methods: The study sample (N = 90) consisted of 45 CT participants and 45 matched non-participants from archival data from our prior CC studies. 171 patients who participated in therapeutic cancer clinical trials through the Hawaii Minority/Underserved NCI Community Oncology Research Program (NCORP) between 2015 and 2020 were contacted for study participation, and 26% completed the CCI. The CCI measures overall perceptions of CC and across 3 domains (Communication, Navigation, Operational). Paired t-tests were used to compare overall and domain scores between CT participants and non-participants. The two groups were matched by age, gender, cancer type (breast, GI, other), and clinical stage. Results: Among CT participants, the mean age was 61.7 ( SD = 9.4), and the majority were female (67%) and Asian (56%). The most common cancer types were breast (27%) and GI (16%), with 24% with stage III disease. CT participants reported significantly higher total CC scores than non-participants (62.5 vs. 55.8; p = .0008). Similar trends were found for Navigation ( p = .007) and Operational ( p = .001) domain scores. 29% of CT participants reported receiving high-intensity CC assistance from their clinical research associates (CRAs), and 27% indicated receiving moderate-level CC assistance. Responses to open-ended questions regarding CC revealed that CT participants received assistance with a variety of CC activities from their CRAs, including scheduling appointments and explaining test results and procedures. Conclusions: Patients who participate in therapeutic cancer clinical trials report more positive perceptions of CC compared to non-participants. Qualitative data suggest that significant care coordination support is provided by the clinical research associate. The results underscore the importance of CC support provided by CRAs who may be an unrecognized component of the healthcare delivery team. CC provided by CRAs may contribute to improved quality and value of cancer care for patients enrolled on therapeutic clinical trials.

Abstract
We report on the increase in the accelerated electron number and energy using compound parabolic concentrator (CPC) targets from a short-pulse (∼150 fs), high-intensity (>10^{18} W/cm^{2}), and high-contrast (∼10^{8}) laser-solid interaction. We report on experimental measurements using CPC targets where the hot-electron temperature is enhanced up to ∼9 times when compared to planar targets. The temperature measured from the CPC target is 〈T_{e}〉=4.4±1.3 MeV. Using hydrodynamic and particle in cell simulations, we identify the primary source of this temperature enhancement is the intensity increase caused by the CPC geometry that focuses the laser, reducing the focal spot and therefore increasing the intensity of the laser-solid interaction, which is also consistent with analytic expectations for the geometrical focusing.

Abstract
Health professionals have the potential to address the health threats posed by climate change in many ways. This study sought to understand the factors that influence health professionals' willingness to engage in climate advocacy. We hypothesized and tested a model with six antecedent factors predicting willingness to engage in advocacy for strengthening global commitments to the Paris Agreement. Using survey data from members of health professional associations in 12 nations (n = 3,977), we tested the hypothesized relationships with structural equation modeling. All of the hypothesized relationships were confirmed. Specifically, higher rates of perceived expert consensus about human-caused climate change predicted greater climate change belief certainty and belief in human causation. In turn, all three of these factors, including higher levels of perceived health harms from climate change, positively predicted affective involvement with the issue. Affective involvement positively predicted the feeling that health professionals have a responsibility to deal with climate change. Lastly, this sense that climate advocacy is a responsibility of health professionals strongly predicted willingness to advocate. As a unique study of predictors of health professionals' willingness to advocate for climate change, our findings provide unique insight into how an influential set of trusted voices might be activated to address what is arguably the world's most pressing public health threat. Limitations of the study and suggestions for future research are presented, and implications for message development are discussed.

Abstract
BACKGROUND Due to insufficient accuracy, urine-based assays currently have a limited role in the management of patients with bladder cancer. The identification of multiplex molecular signatures associated with disease has the potential to address this deficiency and to assist with accurate, non-invasive diagnosis and monitoring. METHODS To evaluate the performance of Oncuria™, a multiplex immunoassay for bladder detection in voided urine samples. The test was evaluated in a multi-institutional cohort of 362 prospectively collected subjects presenting for bladder cancer evaluation. The parallel measurement of 10 biomarkers (A1AT, APOE, ANG, CA9, IL8, MMP9, MMP10, PAI1, SDC1 and VEGFA) was performed in an independent clinical laboratory. The ability of the test to identify patients harboring bladder cancer was assessed. Bladder cancer status was confirmed by cystoscopy and tissue biopsy. The association of biomarkers and demographic factors was evaluated using linear discriminant analysis (LDA) and predictive models were derived using supervised learning and cross-validation analyses. Diagnostic performance was assessed using ROC curves. RESULTS The combination of the 10 biomarkers provided an AUROC 0.93 [95% CI 0.87-0.98], outperforming any single biomarker. The addition of demographic data (age, sex, and race) into a hybrid signature improved the diagnostic performance AUROC 0.95 [95% CI 0.90-1.00]. The hybrid signature achieved an overall sensitivity of 0.93, specificity of 0.93, PPV of 0.65 and NPV of 0.99 for bladder cancer classification. Sensitivity values of the diagnostic panel for high-grade bladder cancer, low-grade bladder cancer, MIBC and NMIBC were 0.94, 0.89, 0.97 and 0.93, respectively. CONCLUSIONS Urinary levels of a biomarker panel enabled the accurate discrimination of bladder cancer patients and controls. The multiplex Oncuria™ test can achieve the efficient and accurate detection and monitoring of bladder cancer in a non-invasive patient setting.

Abstract
Long non-coding RNAs (lncRNAs) have important biological functions, but their involvement in ovarian cancer remains elusive. We analyzed high-throughput data to identify lncRNAs associated with ovarian cancer outcomes. Our search led to the discovery of lncRNA TOPORS Antisense RNA 1 (TOPORS-AS1). Patients with high TOPORS-AS1 expression had favorable overall survival compared to low expression. This association was replicated in our study and confirmed by meta-analysis. In vitro experiments demonstrated that overexpressing TOPORS-AS1 in ovarian cancer cells suppressed cell proliferation and inhibited aggressive cell behaviors, including migration, invasion, and colony formation. Analysis of tumor cell transcriptomes indicated TOPORS-AS1′s influence on the Wnt/β-catenin signaling. Additional experiments revealed that TOPORS-AS1 increased the phosphorylation of β-catenin and suppressed the expression of CTNNB1, disrupting the Wnt/β-catenin pathway. Our experiments further discovered that vitamin D receptor (VDR) upregulated TOPORS-AS1 expression and that inhibition of β-catenin by TOPORS-AS1 required a RNA binding protein, hnRNPA2B1 (heterogeneous nuclear ribonucleoprotein A2B1). Taken together, these findings suggest that TOPORS-AS1 may behave like a tumor suppressor in ovarian cancer through interrupting the Wnt/β-catenin signaling and that VDR upregulates the expression of TOPORS-AS1. Assessing TOPORS-AS1 expression in ovarian cancer may help predict disease prognosis and develop treatment strategy

Abstract
Background The COVID-19 pandemic has significantly impacted mental health and well-being. Mobile mental health apps can be scalable and useful tools in large-scale disaster responses and are particularly promising for reaching vulnerable populations. COVID Coach is a free, evidence-informed mobile app designed specifically to provide tools and resources for addressing COVID-19–related stress. Objective The purpose of this study was to characterize the overall usage of COVID Coach, explore retention and return usage, and assess whether the app was reaching individuals who may benefit from mental health resources. Methods Anonymous usage data collected from COVID Coach between May 1, 2020, through October 31, 2020, were extracted and analyzed for this study. The sample included 49,287 unique user codes and 3,368,931 in-app events. Results Usage of interactive tools for coping and stress management comprised the majority of key app events (n=325,691, 70.4%), and the majority of app users tried a tool for managing stress (n=28,009, 58.8%). COVID Coach was utilized for ≤3 days by 80.9% (n=34,611) of the sample whose first day of app use occurred within the 6-month observation window. Usage of the key content in COVID Coach predicted returning to the app for a second day. Among those who tried at least one coping tool on their first day of app use, 57.2% (n=11,444) returned for a second visit; whereas only 46.3% (n=10,546) of those who did not try a tool returned (P<.001). Symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD) were prevalent among app users. For example, among app users who completed an anxiety assessment on their first day of app use (n=4870, 11.4% of users), 55.1% (n=2680) reported levels of anxiety that were moderate to severe, and 29.9% (n=1455) of scores fell into the severe symptom range. On average, those with moderate levels of depression on their first day of app use returned to the app for a greater number of days (mean 3.72 days) than those with minimal symptoms (mean 3.08 days; t1=3.01, P=.003). Individuals with significant PTSD symptoms on their first day of app use utilized the app for a significantly greater number of days (mean 3.79 days) than those with fewer symptoms (mean 3.13 days; t1=2.29, P=.02). Conclusions As the mental health impacts of the pandemic continue to be widespread and increasing, digital health resources, such as apps like COVID Coach, are a scalable way to provide evidence-informed tools and resources. Future research is needed to better understand for whom and under what conditions the app is most helpful and how to increase and sustain engagement.

Abstract
Abstract
Background:Breast cancer incidence and mortality rate differ across racial/ethnic population in the US, little is known about Asian and Pacific Island subpopulations. For the Asian subgroups (Japanese, Chinese, Korean, Filipino, Vietnamese, etc.) in the U.S., overall incidence has increased over recent decades. From 2012-2016 Hawai’i incidence rates were significantly higher than the US overall for breast cancer, although cancer mortality rates in Hawai’i were significantly lower than the US overall for breast cancer. Significant disparities in breast cancer incidence and mortality exist, with Native Hawaiian and Filipino women particularly affected. Native Hawaiian women have the highest incidence and also have a 50% higher risk of breast cancer mortality compared to White women. In addition, there are dramatic racial/ethnic differences in mortality rates in the state, with Native Hawaiians having the highest mortality rates compared to all other major racial/ethnic groups.
Methods:We examined unique breast cancer cases in a major health system in Hawai’i from 2013-2019 according to race/ethnicity. We found statically significant differences in breast cancer subtype according to race/ethnicity and menopausal status.
Results:In 561 premenopausal breast cancer cases, we found that Native Hawaiians were less likely to have triple negative breast cancer (OR 0.2, p=0.02) and Japanese were less likely to have triple positive breast cancer (OR 0.17, p=0.002) compared to other race/ethnicities. In 1,954 postmenopausal breast cancer cases, we found that Filipino women were more likely to have hormone negative/HER2 positive breast cancer (OR 2.38, p=0.006) compared to other race/ethnicities.

Table 2-Breast cancer subtype according to race/ethnicity in postmenopausal women
Summary:Although behavioral, environmental, social, economic, and biological factors have been shown to influence risk and survival for breast cancer, they do not entirely explain the differences observed across populations. These findings show the need to characterize the underlying differences in breast tumor biology of breast cancer patients from different racial/ethnic groups to better understand known health disparities. Our hypothesis is that molecular characteristics are key contributors to the disparities in disease outcome across the different racial/ethnic groups. We have previously shown the importance of the tumor microenvironment differences in racial/ethnic groups in our population.

Abstract
BACKGROUND As smartphones are now used by most Americans, it is increasingly possible for mental health mobile apps to be disseminated to the general public. However, little is known about how mobile mental health apps are used by the general population outside of a controlled research design. OBJECTIVE Our objective is to describe how the general population engages with Mindfulness Coach, an iOS- and Android-based app designed to deliver a mindfulness training course. METHODS Using anonymous download and analytics data, we characterized the reach, usage, retention, and impact of Mindfulness Coach. We included mobile analytics data from all unique downloads of Mindfulness Coach between August 1, 2018, and April 8, 2019 (N=104,067) as well as starred reviews from all Mindfulness Coach users who provided reviews of the app as of March 1, 2020. Mindfulness characteristics were measured by an in-app assessment using the Five-Facet Mindfulness Questionnaire-Short Form (FFMQ-SF). RESULTS Users engaged, on average, in 4.3 visits to the app (SD 8.8; median 2; 90th percentile 8) and associated with an average total of 49.2 interactions with the app (ie, clicks within the app) (SD 113.8; median 19; 90th percentile 105). Users spent an average of 16.2 minutes (SD 63.1) engaged with the app over the full study time period. There were strong linear effects of app engagement on total FFMQ-SF scores. For example, FFMQ-SF scores were associated with more time spent engaged with the app (R2=.23; P<.001). Mindfulness Coach has been reviewed in the Google Play Store 3415 times, with an average rating of 4.7 out of 5 stars, and over 2000 times in the Apple App Store, with an average rating of 4.8 out of 5 stars. CONCLUSIONS These findings suggest that Mindfulness Coach has achieved substantial and sustained reach in the general population; however, it was used less frequently by many downloaders than researchers and designers intended. There was a subpopulation of users who engaged in the app regularly over an extended period of time, and there was a clear relationship between app use and improvements in mindfulness. To strengthen Mindfulness Coach's public health impact, more research is needed to understand who is using the app and how, and to design strategies to increase user engagement in order for users to receive a larger dose of mindfulness treatment.

Abstract
PURPOSE Knowledge about the health consequences of e-cigarette use in adolescence remains limited. Available studies of asthma among adolescents are based on data collected five or more years ago, and evidence from more recent generations of e-cigarette products is needed. METHODS We analyzed data from the 2017 Youth Risk Behavior Survey, a cross-sectional study with a representative U.S. national sample of high school students. Multivariable analyses tested for associations of ever and 30-day e-cigarette use with asthma controlling for cigarette smoking, marijuana use, demographics, and obesity. RESULTS A significant association with asthma was found for ever use of e-cigarettes, adjusted odds ratio (AOR) = 1.15 (confidence interval [CI], 1.02-1.30; p = .02) and for currently using e-cigarettes, AOR = 1.30 (CI, 1.10-1.53; p = .002). Also related to asthma were current cigarette smoking, AOR = 1.24 (CI, 1.03-1.51; p = .03) and obesity, AOR = 1.48 (CI, 1.30-1.68; p < .0001). E-cigarettes had an additive effect for asthma beyond smoking (p = .03). Differentials in asthma prevalence by race/ethnicity were found, with lower prevalence of asthma for non-Hispanic Asian (p = .02) and Hispanic (p = .03) and higher prevalence for non-Hispanic black (p < .0001) and non-Hispanic multirace (p < .0001) relative to non-Hispanic white populations. CONCLUSIONS E-cigarette use was significantly associated with asthma in recent data on adolescents, controlling for several disease-relevant covariates. The results are consistent with studies based on previous generations of e-cigarettes and support the significance of e-cigarettes as a continuing public health concern.

Abstract
Background To communicate research to the public, the National Cancer Institute developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance, including the Behavioral Risk Factor Surveillance System, HINTS data are not sufficient to address unique demographic subpopulations such as US Pacific Islanders (PIs). National sampling methods do not adequately reach participants from small, medically underserved populations. Aim This study aims to document the cancer-relevant knowledge, attitudes, behaviors, and information-seeking practices of PIs in Hawaii (HI). Methods We conducted a cross-sectional survey during 2017-2018 of Native Hawaiians, Chuukese, and Marshallese in HI using Respondent Driven Sampling (RDS) to recruit these geographically diffuse groups. The modified HINTS survey included questions about cancer knowledge, attitudes and behaviors, health communications, and cultural practices. Results A total of 515 Native Hawaiians, 305 Chuukese, and 180 Marshallese completed the survey. Differences were found across a variety of cancer-related attitudes, knowledge, and behaviors. These groups also differed regarding acculturation, health locus of control, and trust in medical professionals. Native Hawaiians were significantly more acculturated (P=.0001) than Chuukese or Marshallese and more likely to smoke cigarettes (P=.0001). Among participants aged >50 years, we found no significant differences across ethnic groups (P=.30) for those completing a colon cancer screening (37%). However, only 27% were referred to screening by a physician. Conclusions Cancer prevention programs are greatly needed for PIs in HI. This study provides knowledge concerning the efficiency of RDS to recruit participants, and the role of culture in communications influencing cancer risk behaviors, which may be generalizable to migrant PIs in the United States.

Abstract
Among more than 200 BAP1-mutant families affected by the "BAP1 cancer syndrome," nearly all individuals inheriting a BAP1 mutant allele developed one or more malignancies during their lifetime, mostly uveal and cutaneous melanoma, mesothelioma, and clear-cell renal cell carcinoma. These cancer types are also those that, when they occur sporadically, are more likely to carry somatic biallelic BAP1 mutations. Mechanistic studies revealed that the tumor suppressor function of BAP1 is linked to its dual activity in the nucleus, where it is implicated in a variety of processes including DNA repair and transcription, and in the cytoplasm, where it regulates cell death and mitochondrial metabolism. BAP1 activity in tumor suppression is cell type- and context-dependent. BAP1 has emerged as a critical tumor suppressor across multiple cancer types, predisposing to tumor development when mutated in the germline as well as somatically. Moreover, BAP1 has emerged as a key regulator of gene-environment interaction.This article is highlighted in the In This Issue feature, p. 1079.

Abstract
BACKGROUND A 2012 World Health Organization report recognizes betel nut use as an urgent public health threat faced by the Western Pacific region. However, compared with other addictive substances, little is known about how betel nuts are depicted on social media platforms. In particular, image-based social media platforms can be powerful tools for health communication. Studying the content of substance use on visual social media may provide valuable insights into public health interventions. OBJECTIVE This study aimed to explore and document the ways that betel nut is portrayed on the photo-sharing site Instagram. The analysis focuses on the hashtag #pugua, which refers to the local term for betel nut in Guam and other parts of Micronesia. METHODS An exploratory content analysis of 242 Instagram posts tagged #pugua was conducted based on previous research on substance use and Instagram and betel nut practices in Micronesia. In addition, the study examined the social engagement of betel nut content on the image-based platform. RESULTS The study findings revealed content themes referencing the betel nut or betel nut tree, betel nut preparation practices, and the unique social and cultural context surrounding betel nut activity in Guam and Micronesia. In addition, certain practices and cultural themes encouraged social engagement on Instagram. CONCLUSIONS The findings from this study emphasize the cultural relevance of betel nut use in Micronesia. These findings provide a basis for empirically testing hypotheses related to the etiological roles of cultural identity and pride in shaping betel nut use behavior among Micronesians, particularly youths and young adults. Such research is likely to inform the development of culturally relevant betel nut prevention and cessation programs.

Abstract
e19026 Background: Cancer surgeries performed at high case volume centers (hCVCs) are associated with improved surgical and clinical outcomes. Resectable hepatocellular carcinoma (rHCC) is not common in the US and the impact of surgery at hCVCs has not been well assessed. We analyzed the impact of surgery at hCVCs on survival, and the potential racial and socioeconomic disparities associated with obtaining care at hCVCs. Methods: We collected demographic, diagnostic, treatment, and survival data of 96,215 patients with stage I-III HCC diagnosed between 2004 – 2015 from the National Cancer Database. To estimate the average surgical volume/year, number of reported cases were divided by the number of years the facility was represented in the database. Logistic regression was used to determine the associations between case volume, facility type and the demographic and clinical variables. We assessed demographic and clinical predictors of overall survival (OS) using Cox proportional hazards regression. Results: In total, 10,419 resected HCC patients were included in the analysis. The median age was 64 (18 – 90), 68.4% were male and 69.5% were white. Facilities were divided into quartiles by average number of surgical CV/year: 1st quartile (1Q) 0.08-1.60, 2Q 1.61 – 3.91, 3Q 3.92 – 8.34, and 4Q 8.35 – 45.34. In a multivariate model, improved OS was seen with each increase in quartiles with the highest CVCs (i.e 4Q) HR 0.70 (95% CI 0.63 – 0.77). Treatment at academic centers did not show an OS advantage (HR 0.93; 95% CI 0.86 – 1.01). Factors including black race (OR 0.83; 95% CI 0.75-0.93), age 65+ (OR 0.91; 95% CI 0.82 – 1.00), and living in a metro area with a population of 250,000 – 1 million people (OR 0.68; 95% CI 0.62 – 0.74) were less likely to be associated with treatment at hCVCs. Conversely, Asians/Pacific Islanders (OR 2.28; 95% CI 2.04 – 2.55) and those with private insurance (OR 1.33; 95% CI 1.18– 1.40) or Medicare (OR 1.21; 95% CI 1.05 – 1.38) were more likely to be treated at hCVCs. Conclusions: rHCC is not common in the US and having surgery at hCVCs improves OS. However, racial and socioeconomic disparities exist in receiving care at these hCVCs.
