Cancer incidence and mortality patterns among specific Asian and Pacific Islander populations in the U.S

Racial, Ethnic, and Gender Differences in the Timing of Initiating the HPV Vaccine in the United States: the Case of Southeast Asian Americans

Despite the availability of the human papillomavirus (HPV) vaccine, non-Latinx (NL) Southeast Asian Americans have the highest incidence of HPV-associated cervical cancer in the US. Little is known about NL-Southeast Asian Americans' HPV vaccination coverage due to being categorized under the "Asian American" monolith. Therefore, this study uses restricted data from the 2011-2018 National Health and Nutrition Examination Survey (NHANES) to disaggregate NL-Southeast Asian Americans and compare this population's age-specific probabilities of initiating HPV vaccinations to two Asian American subgroups (NL-East Asian and NL-South Asian Americans) and NL-White, NL-Black, and Latinx Americans. Multinomial logistic regression models examine the differences in the timing of initiating the HPV vaccine series, late (ages 13-26) or never, relative to on-time vaccination (by age 12). NL-Southeast Asian Americans are significantly more likely to never vaccinate and to vaccinate late than NL-White, NL-Black, and Latinx Americans, relative to on-time vaccination. NL-Southeast Asian American boys/men are significantly more likely to never initiate the HPV vaccine than Latinx boys/men, relative to on-time vaccination. NL-Southeast Asian American girls/women are significantly more likely to never vaccinate and vaccinate late than NL-White, NL-Black, and Latinx girls/women, relative to on-time vaccination. There are significant gender differences in uptake among all racial and ethnic groups, except among NL-Southeast and NL-East Asian Americans. Disaggregated data on NL-Southeast Asian Americans helps scholars and public health officials uncover health disparities and improve health interventions. Targeted HPV vaccine promotion and services for this population are needed to mitigate current and future health disparities and promote health equity.

Genomic profiles of Japanese patients with vulvar squamous cell carcinoma

The incidence of vulvar carcinoma varies by race; however, it is a rare disease, and its genomic profiles remain largely unknown. This study examined the characteristics of vulvar squamous cell carcinoma (VSCC) in Japanese patients, focusing on genomic profiles and potential racial disparities. The study included two Japanese groups: the National Cancer Center Hospital (NCCH) group comprised 19 patients diagnosed between 2015 and 2023, and the Center for Cancer Genomics and Advanced Therapeutics group comprised 29 patients diagnosed between 2019 and 2022. Somatic mutations were identified by targeted or panel sequencing, and TP53 was identified as the most common mutation (52-81%), followed by HRAS (7-26%), CDKN2A (21-24%), and PIK3CA (5-10%). The mutation frequencies, except for TP53, were similar to those of Caucasian cohorts. In the NCCH group, 16 patients of HPV-independent tumors were identified by immunohistochemistry and genotyping. Univariate analysis revealed that TP53-mutated patients were associated with a poor prognosis (log-rank test, P = 0.089). Japanese VSCC mutations resembled those of Caucasian vulvar carcinomas, and TP53 mutations predicted prognosis regardless of ethnicity. The present findings suggest potential molecular-targeted therapies for select VSCC patients.

Disaggregating the Asian-American Breast Cancer Population: Disparities in Reconstruction Rates

INTRODUCTION

Breast cancer (BC) incidence has been increasing among Asian-Americans (AsAms); recent data suggest these patients are less likely to undergo postmastectomy breast reconstruction (PMBR) compared to non-Asian women. Historically, AsAm BC patients are reported in aggregate, masking heterogeneity within this population. We aim to identify patterns of postmastectomy reconstruction among disaggregated AsAm BC patients at our institution.

METHODS

A retrospective chart review was performed for BC patients who underwent mastectomy between 2017 and 2021. Patient demographic and clinical information was collected including self-reported race/ethnicity and reconstruction at time of mastectomy. Self-identified Asian patients were disaggregated into East Asian, Southeast Asian, South Asian, and 'Asian Other.' We examined rates of reconstruction between the different races and the disaggregated Asian subgroups. Univariable and multivariable analysis was performed to examine patient factors associated with PMBR.

RESULTS

Six hundred and five patients met inclusion criteria. Forty seven percent of patients identified as Asian, 36% of which as East Asian. Forty four percent of all patients underwent PMBR. Southeast Asian and South Asian women were least likely to undergo reconstruction, while Hispanic and non-Hispanic Black women were most likely to pursue PMBR (P = 0.020). On multivariable analysis, Hispanic, non-Hispanic White, and non-Hispanic Black women were more likely to undergo reconstruction compared to Asian women. Other factors associated with reconstruction were coverage with private insurance and diagnosis of noninvasive disease.

CONCLUSIONS

Rates of PMBR are lower among AsAms than non-Asian patients and vary between Asian ethnic subgroups. Further investigation is needed to identify patterns of reconstruction among the disaggregated AsAm population to address disparities.

Reproductive risk factors for breast cancer and association with novel breast density measurements among Hispanic, Black, and White women

PURPOSE

There are differences in the distributions of breast cancer incidence and risk factors by race and ethnicity. Given the strong association between breast density and breast cancer, it is of interest describe racial and ethnic variation in the determinants of breast density.

METHODS

We characterized racial and ethnic variation in reproductive history and several measures of breast density for Hispanic (n = 286), non-Hispanic Black (n = 255), and non-Hispanic White (n = 1694) women imaged at a single hospital. We quantified associations between reproductive factors and percent volumetric density (PVD), dense volume (DV), non-dense volume (NDV), and a novel measure of pixel intensity variation (V) using multivariable-adjusted linear regression, and tested for statistical heterogeneity by race and ethnicity.

RESULTS

Reproductive factors most strongly associated with breast density were age at menarche, parity, and oral contraceptive use. Variation by race and ethnicity was most evident for the associations between reproductive factors and NDV (minimum p-heterogeneity:0.008) and V (minimum p-heterogeneity:0.004) and least evident for PVD (minimum p-heterogeneity:0.042) and DV (minimum p-heterogeneity:0.041).

CONCLUSION

Reproductive choices, particularly those related to childbearing and oral contraceptive use, may contribute to racial and ethnic variation in breast density.

Accuracy of patient race and ethnicity data in a central cancer registry

PURPOSE

Race and Hispanic ethnicity data can be challenging for central cancer registries to collect. We evaluated the accuracy of the race and Hispanic ethnicity variables collected by the Utah Cancer Registry compared to self-report.

METHODS

Participants were 3,162 cancer survivors who completed questionnaires administered in 2015-2022 by the Utah Cancer Registry. Each survey included separate questions collecting race and Hispanic ethnicity, respectively. Registry-collected race and Hispanic ethnicity were compared to self-reported values for the same individuals. We calculated sensitivity and specificity for each race category and Hispanic ethnicity separately.

RESULTS

Survey participants included 323 (10.2%) survivors identifying as Hispanic, a lower proportion Hispanic than the 12.1% in the registry Hispanic variable (sensitivity 88.2%, specificity 96.5%). For race, 43 participants (1.4%) self-identified as American Indian or Alaska Native (AIAN), 32 (1.0%) as Asian, 23 (0.7%) as Black or African American, 16 (0.5%) Pacific Islander (PI), and 2994 (94.7%) as White. The registry race variable classified a smaller proportion of survivors as members of each of these race groups except White. Sensitivity for classification of race as AIAN was 9.3%, Asian 40.6%, Black 60.9%, PI 25.0%, and specificity for each of these groups was > 99%. Sensitivity and specificity for White were 98.8% and 47.4%.

CONCLUSION

Cancer registry race and Hispanic ethnicity data often did not match the individual's self-identification. Of particular concern is the high proportion of AIAN individuals whose race is misclassified. Continued attention should be directed to the accurate capture of race and ethnicity data by hospitals.

An increase in SNHG5 expression is associated with poor cancer prognosis, according to a meta-analysis

BACKGROUND

He long noncoding RNA small nucleolar host RNA 5 (SNHG5) is highly expressed in many cancers, and there is a notable correlation between the elevated expression of SNHG5 and survival outcome in cancer patients. The objective of this study was to conduct a meta-analysis to evaluate the correlation between SNHG5 expression and the clinical outcome of cancer patients.

METHODS

Six relevant electronic databases were exhaustively searched, and, depending on the inclusion and exclusion criteria, appropriate literature was obtained. The Newcastle-Ottawa Scale (NOS) score was utilized to evaluate the quality of the research for every article included, and pertinent data from each study were carefully extracted. Hazard ratios (HRs), odds ratios (ORs) and 95% confidence intervals (CIs) were combined to explore the association of SNHG5 expression levels with cancer prognosis, and sensitivity analyses and assessments of publication bias were also conducted to investigate any possibility in the publication of the studies.

RESULTS

Eleven studies encompassing 721 patients were ultimately collected. When combined, the hazard ratios (HRs) revealed a substantial direct correlation between elevated SNHG5 expression and an unfavourable prognosis for cancer patients (HR = 1.90, 95% CI 0.87-4.15); however, the correlation did not reach statistical significance. Furthermore, high SNHG5 expression was predictive of advanced TNM stage (OR: 1.988, 95% CI 1.205-3.278) and larger tumour size (OR: 1.571, 95% CI 1.090-2.264); moreover, there were nonsignificant relationships between SNHG5 expression and DM (OR: 0.449, 95% CI 0.077-2.630), lymph node metastasis (OR: 1.443, 95% CI 0.709-2.939), histological grade (OR: 2.098, 95% CI 0.910-4.838), depth of invasion (OR: 1.106, 95% CI 0.376-3.248), age (OR: 0.946, 95% CI 0.718-1.247) and sex (OR: 0.762, 95% CI 0.521-1.115).

CONCLUSION

SNHG5 expression is typically increased in the majority of tumour tissues. Elevated SNHG5 expression may indicate poor prognosis in cancer patients. Therefore, SNHG5 is a promising potential therapeutic target for tumours and a reliable prognostic biomarker.

The adverse characteristics of hepatocellular carcinoma in the non-cirrhotic liver disproportionately disadvantage Black patients

BACKGROUND

Black patients have higher hepatocellular carcinoma (HCC)-related mortality than White patients and more often develop HCC in non-cirrhotic liver. HCC surveillance is primarily directed toward cirrhotic patients. We aimed to characterize HCC in non-cirrhotic patients and to identify factors associated with HCC beyond Milan criteria.

METHODS

Demographic, imaging, laboratory, and pathology data of HCC patients at our institution, 2003-2018, were reviewed, retrospectively. Race/ethnicity were self-reported. Cirrhosis was defined as a Fibrosis-4 score ≥3.25.

RESULTS

Compared to 1146 cirrhotic patients, 411 non-cirrhotic patients had larger tumors (median 4.7 cm vs. 3.1 cm, p < 0.01) and were less likely to be within Milan criteria (42.6% vs. 57.7%, p < 0.01). Among non-cirrhotic patients, Black patients had larger tumors (4.9 cm vs. 4.3 cm, p < 0.01) and a higher percentage of poorly differentiated tumors (39.4% vs. 23.1%, p = 0.02). Among cirrhotic patients, Black patients had larger tumors (3.3 cm vs. 3.0 cm, p = 0.03) and were less likely to be within Milan criteria (52.3% vs. 83.2%, p < 0.01). In multivariable analysis, lack of commercial insurance (OR 1.45 [CI 95% 1.19-1.83], p < 0.01), male sex (OR 1.34 [CI 95% 1.05-1.70], p < 0.01), absence of cirrhosis (OR 1.58 [CI 95% 1.27-1.98], p < 0.01) and Black race/ethnicity (OR 1.34 [CI 95% 1.09-1.66], p = 0.01) were associated with HCC beyond Milan criteria. Black patients had lower survival rates than other patients (p < 0.01).

CONCLUSIONS

Non-cirrhotic patients had more advanced HCC than cirrhotic patients. Black patients (with or without cirrhosis) had more advanced HCC than comparable non-Black patients and higher mortality rates. Improved access to healthcare (commercial insurance) may increase early diagnosis (within Milan criteria) and reduce disparities.

Risk of contralateral breast cancer among Asian/Pacific Islander women in the United States

PURPOSE

While breast cancer studies often aggregate Asian/Pacific Islander (API) women, as a single group or exclude them, this population is heterogeneous in terms of genetic background, environmental exposures, and health-related behaviors, potentially resulting in different cancer outcomes. Our purpose was to evaluate risks of contralateral breast cancer (CBC) among subgroups of API women with breast cancer.

METHODS

We conducted a retrospective cohort study of women ages 18 + years diagnosed with stage I-III breast cancer between 2000 and 2016 in the Surveillance, Epidemiology and End Results registries. API subgroups included Chinese, Japanese, Filipina, Native Hawaiian, Korean, Vietnamese, Indian/Pakistani, and other API women. Asynchronous CBC was defined as breast cancer diagnosed in the opposite breast 12 + months after first primary unilateral breast cancer. Multivariable-adjusted subdistribution hazard ratios (SHR) and 95% confidence intervals (CI) were estimated and stratified by API subgroups.

RESULTS

From a cohort of 44,362 API women with breast cancer, 25% were Filipina, 18% were Chinese, 14% were Japanese, and 8% were Indian/Pakistani. API women as an aggregate group had increased risk of CBC (SHR 1.15, 95% CI 1.08-1.22) compared to NHW women, among whom Chinese (SHR 1.23, 95% CI 1.08-1.40), Filipina (SHR 1.37, 95% CI 1.23-1.52), and Native Hawaiian (SHR 1.69, 95% CI 1.37-2.08) women had greater risks.

CONCLUSION

Aggregating or excluding API patients from breast cancer studies ignores their heterogeneous health outcomes. To advance cancer health equity among API women, future research should examine inequities within the API population to design interventions that can adequately address their unique differences.

Clinical profile of FTL3-ITD mutation in West Algerian population with acute myeloid leukemia

Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the abnormal and rapid growth of cells. The mutation of the Fms-like tyrosine kinase 3 ligand gene (FLT3-ITD) represents an important factor in the prognosis of AML. The objective of this study was to determine for the first time the prevalence of FLT3-ITD mutation in west Algerian AML patients. A total of 160 AML patients were genotyped for FLT3-ITD mutation by using polymerase chain reaction. FLT3-ITD mutation was detected in 13% of patients. Mutation rates show no significant difference in the distribution of sex and age. A positive association was found between this mutation and a higher leukocyte and blast cells counts. We also found that the M3 and M5 subtype were the commonest in the FLT3 mutated group. This preliminary study provides first-time prevalence estimates for FLT3-ITD mutation in acute myeloid leukemia patients from the West region of Algeria.

Barriers to Type 2 Diabetes Mellitus Management for Older Hmong Patients with Minimal English Language Skills: Accounts from Caregivers, Case Managers, and Clinicians

Type 2 diabetes mellitus prevalence rates for Hmong Americans in Wisconsin are more than double that of non-Hispanic Whites. The Hmong's history, lifestyle (dietary and behavioral patterns), and reliance on traditional medicine contribute to their increased risk of diabetes. This qualitative study aimed to better understand the barriers challenging older Hmong patients' ability to manage diabetes. Asian Americans have long been overlooked in health-related research, but recent disaggregated data of specific ethnic groups reveal significant health inequities. Among the different ethnic groups, there is a significant lack of research on the Hmong Americans. Three participant groups (Hmong American family caregivers, Hmong American case managers, and clinicians from different racial backgrounds who provide care for Hmong patients) were recruited from the community and interviewed to understand the barriers experienced by older Hmong patients with minimal English language skills in managing their diabetes. Directed content analysis of the data resulted in three major themes: adherence to culture, health inequity, and managing diabetes. Subthemes included Hmong herbs and shamans, lack of trust in Western medicine, the significance of rice, language barriers, lack of cultural sensitivity, health literacy, monitoring glucose, medicine compliance, and nutrition. Minimal English language skills and low literacy rates (health and education) contribute to their strong adherence to cultural practices which challenges Western medicine, creating difficulty for older Hmong patients to manage their diabetes. Recognizing cultural differences and barriers will enable healthcare providers to improve and cater the treatment options, bridging the gap between older Hmong patients and Western medicine.

The effectiveness of patient navigation services in reducing cancer screening disparities among Asian Americans

OBJECTIVES

Patient navigation has served as a useful intervention to reduce cancer disparities among diverse ethnic groups. Previous studies have consistently shown the effectiveness of patient navigation in reducing cancer disparities for ethnic minorities; however, few studies have been conducted for cancer screening behaviors focusing on the Asian population. This study aims to identify the overall effectiveness of patient navigation in cancer screening behaviors among Asian Americans through meta-analyses. In addition, this study examines the moderating effects of the type of cancers on cancer screening behaviors.

DESIGN

For data analyses, we selected 15 studies through a systematic review and meta-analyses, searching the databases of PubMed, Web of Science, Embase, Scopus, and Cochrane Library. Random-effects models were used for meta-analyses.

RESULTS

The results showed that Asian Americans who received patient navigation were more likely to participate in cancer screening behaviors than those who did not receive patient navigation regardless of the type of cancer. Publication bias was tested using a funnel plot, meta-regression, and Failsafe-N. No notable publication bias was found.

CONCLUSION

This study can provide comprehensive evidence regarding the overall effectiveness of patient navigation in cancer screening behaviors of Asian Americans.

Tips to Quit Smoking: Perspectives from Vietnamese Healthcare Providers, Community Leaders, and Past Tobacco Users in the United States

This study focuses on smoking-cessation strategies for United States (US) Vietnamese individuals, a group with high smoking rates, particularly those with limited English proficiency (LEP). The researchers conducted 16 in-depth interviews with a diverse group of participants, including healthcare professionals, community leaders, and former tobacco users. Data were analyzed using the Phase-Based Model of smoking cessation, resulting in several helpful strategies across the four phases: Motivation, Preparation, Cessation, and Maintenance. Prominent advice for the Motivation Phase included having a strong determination to quit and a reason why, such as protecting loved ones. For the Preparation and Cessation Phases, participants recommended healthy coping mechanisms, avoiding triggers, changing habits, and gradually reducing the number of cigarettes smoked. In the Maintenance Phase, strategies included regular exercise and setting boundaries with other people who smoke. Participants also stressed the importance of social support throughout all four phases. These findings have implications for healthcare providers working with US Vietnamese who smoke, especially those with LEP. By understanding the unique challenges this group faces in accessing smoking-cessation resources, providers can offer tailored support and guidance. Ultimately, this study provides useful strategies for helping US Vietnamese quit smoking, improving their health outcomes and quality of life.

Changes in Breast Cancer Risk and Risk Factor Profiles among U.S.-Born and Immigrant Asian American Women Residing in the San Francisco Bay Area

BACKGROUND

Breast cancer incidence rates in women of Asian descent have been increasing in the United States and Asia.

METHODS

In a case-control study of Asian American women from the San Francisco Bay Area, we assessed associations with birthplace and migration-related characteristics and compared risk factors between Asian American and non-Hispanic White women by birthplace and birth cohort.

RESULTS

Birthplace and migration-related characteristics were associated with breast cancer risk only among women in the younger birth cohort (1951-1984) that comprised 355 cases diagnosed at age ≤55 years and 276 sister and population controls. Breast cancer risk was marginally increased among foreign-born women [OR = 1.40; 95% confidence interval (CI), 0.97-2.03] and two-fold among foreign-born Chinese women (OR = 2.16; 95% CI, 1.21-3.88). Two-fold increased risks were associated with migration at age ≥40 years and longer U.S. residence (≥30 years or ≥75% of life). The education level was high among both cases and controls. Differences in the prevalence of risk factors by birthplace and birth cohort suggest temporal changes in reproductive and lifestyle-related factors. The prevalence in risk factors was similar between foreign-born and U.S.-born women in the younger birth cohort, and did not fully explain the observed associations with birthplace and other migration characteristics.

CONCLUSIONS

In contrast to studies from earlier decades, younger foreign-born Asian American women had a higher risk of breast cancer than U.S.-born Asian American women.

IMPACT

It is important and urgent to understand what factors drive the increasing burden of breast cancer in women of Asian descent and implement effective prevention programs.

Lung Cancer Incidence by Detailed Race-Ethnicity

Lung cancer (LC) incidence rates and tumor characteristics among (non-Hispanic) Black and Hispanic detailed groups, normally characterized in aggregate, have been overlooked in the US. We used LC data from the Florida state cancer registry, 2012-2018, to compute LC age-adjusted incidence rates (AAIR) for US-born Black, Caribbean-born Black, Mexican, Puerto Rican, Cuban, Dominican, and Central and South American populations. We analyzed 120,550 total LC cases. Among Hispanics, Cuban males had the highest AAIR (65.6 per 100,000; 95%CI: 63.6-67.6), only 8% [Incidence Rate Ratio (IRR): 0.92; 95%CI: 0.89-0.95] lower than Whites, but 2.7 (IRR 95%CI: 2.31-3.19) times higher than Central Americans. Among Blacks, the AAIR for US-born Black males was over three times that of those Caribbean-born (IRR: 3.12; 95%CI: 2.80-3.40) and 14% higher than White males (IRR: 1.14; 95%CI: 1.11-1.18). Among women, US-born Blacks (46.4 per 100,000) and foreign-born Mexicans (12.2 per 100,000) had the highest and lowest rates. Aggregation of non-Hispanic Blacks or Hispanics obscures inherent disparities within groups. Understanding the distinct LC rates in US populations is crucial for targeting public health measures for LC diagnosis, prevention, and treatment. Further LC research exploring detailed race-ethnicity regarding LC in never-smokers is necessary, particularly among females and considering pertinent environmental factors.

The Landmark Series: The Breast Cancer Burden of the Asian American Population and the Need for Disaggregated Data

The Asian American Pacific Islander (AAPI) population is a heterogeneous group of people from geographically and ethnically distinct regions of the world. Traditionally, these patients have been reported as one large aggregate in the breast cancer literature under the race category of "Asian." A detailed examination of this group shows compelling evidence that breast cancer manifests differently among Asian ethnic subgroups, resulting in overlooked health disparities when these races are grouped together. The AAPI community is the fastest growing ethnic group in the United States, and their incidence of breast cancer is increasing at rates greater than among their non-Asian counterparts. When these patients are disaggregated by race, they show wide variations in breast cancer screening, presentation, treatment, and outcomes. This population often faces additional unique challenges in the health care system due to cultural, social, health literacy, and language barriers, which can contribute to further disparity. Our landmark series aims to showcase the breadth of the breast cancer burden in the AAPI population and highlight the need for disaggregated ethnic data.

Lower human papillomavirus vaccine initiation and completion among Asian American adolescents compared to their peers: National Health and Nutritional Examination Survey 2011-2018

PURPOSE

To compare human papillomavirus (HPV) vaccination initiation and completion between Asian American adolescents and their peers.

METHODS

HPV vaccine initiation and completion of adolescents aged 9-17 years old were analyzed using the National Health and Nutritional Examination Survey data from 2011 to 2018. The outcomes were HPV vaccine initiation percentage among all adolescents and completion percentage among initiators. Odds ratios for initiation or completion among Hispanics, Blacks, and Asians (referred to as racial/ethnic minorities) versus Whites were compared using logistic regression, adjusted for adolescent's age, annual family income, parent education, and insurance coverage.

RESULTS

From 2011 to 2018, overall initiation was less than 40% among U.S. adolescents. The initiation increased among boys (from 10% in 2011-12 to over 30% in 2017-2018) but not among girls. Compared to White girls, Black and Hispanic girls were more likely, while Asian girls were less likely to initiate vaccination. Although not statistically significant, Asian girls had ORs ranging from 0.65 to 0.99 for initiation compared to White girls in each of the four survey cycles. Black and Hispanic boys were more likely to initiate vaccination compared to White boys. Initiation among Asian boys increased to 39% in the 2017-2018 survey cycle. Racial/ethnic minority girls were less likely to complete the series compared to White girls, while the opposite was seen in Black boys.

CONCLUSION

HPV vaccination status varies among racial/ethnic groups. Future efforts should be made to achieve the Healthy People 2020 goal of 80% vaccination among U.S. adolescents and address the gap among Asian American girls.

Genetic alterations in CREBRF influence prostate cancer survival and impact prostate tissue homeostasis in mice

BACKGROUND

Risk factors for prostate cancer include age, environment, race and ethnicity. Genetic variants in cyclic-adenosine-monophosphate-response-element-binding protein 3 regulatory factor (CREBRF) gene are frequently observed in Pacific Islanders, a population with elevated prostate cancer incidence. CREBRF has been shown to play a role in other cancers, however its function in prostate homeostasis and tumorigenesis has not been previously explored. We determined the incidence of CREBRF alterations in publicly available databases and examined the impact of CREBRF deletion on the murine prostate in order to determine whether CREBRF impacts prostate physiology or pathophysiology.

METHODS

Alterations in CREBRF were identified in prostate cancer patients via in silico analysis of several publicly available datasets through cBioPortal. Male Crebrf knockout and wild-type littermate mice were generated and examined for prostate defects at 4 months of age. Immunohistochemical staining of murine prostate sections was used to determine the impact of Crebrf knockout on proliferation, apoptosis, inflammation and blood vessel density in the prostate. Serum adipokine levels were measured using a Luminex Multiplex Assay.

RESULTS

CREBRF alterations were identified in up to 4.05% of prostate tumors and the mutations identified were categorized as likely damaging. Median survival of prostate cancer patients with genetic alterations in CREBRF was 41.23 months, compared to 131 months for patients without these changes. In the murine model, the prostates of Crebrf knockout mice had reduced epithelial proliferation and increased TUNEL⁺ apoptotic cells. Circulating adipokines PAI-1 and MCP-1 were also altered in Crebrf knockout mice compared to age-matched controls.

CONCLUSIONS

Prostate cancer patients with genetic alterations in CREBRF had a significantly decreased overall survival suggesting that wild type CREBRF may play a role in limiting prostate tumorigenesis and progression. The murine knockout model demonstrated that CREBRF could modulate proliferation and apoptosis and macrophage density in the prostate. Serum levels of adipokines PAI-1 and MCP-1 were also altered and may contribute to the phenotypic changes observed in the prostates of Crebrf knockout mice. Future studies focused on populations susceptible to CREBRF mutations and mechanistic studies will be required to fully elucidate the potential role of CREBRF in prostate tumorigenesis.

Advancing Health Disparities Research: The Need to Include Asian American Subgroup Populations

BACKGROUND

Despite recognition that the health outcomes of Asian American subgroups are heterogeneous, research has mainly focused on the six largest subgroups. There is limited knowledge of smaller subgroups and their health outcomes. This scoping review identifies trends in the health outcomes, reveals those which are under-researched, and provide recommendations on data collection with 24 Asian American subgroups.

METHODS

Our literature search of peer-reviewed English language primary source articles published between 1991 and 2018 was conducted across six databases (Embase, PubMed, Web of Sciences, CINAHL, PsychINFO, Academic Search Complete) and Google Scholar, yielding 3844 articles. After duplicate removal, we independently screened 3413 studies to determine whether they met inclusion criteria. Seventy-six studies were identified for inclusion in this review. Data were extracted on study characteristics, content, and findings.

FINDINGS

Seventy-six studies met the inclusion criteria. The most represented subgroups were Chinese (n = 74), Japanese (n = 60), and Filipino (n = 60), while Indonesian (n = 1), Malaysian (n = 1), and Burmese (n = 1) were included in only one or two studies. Several Asian American subgroups listed in the 2010 U.S. Census were not represented in any of the studies. Overall, the most studied health conditions were cancer (n = 29), diabetes (n = 13), maternal and infant health (n = 10), and cardiovascular disease (n = 9). Studies showed that health outcomes varied greatly across subgroups.

CONCLUSIONS

More research is required to focus on smaller-sized subgroup populations to obtain accurate results and address health disparities for all groups.

Transcriptome profiling of colorectal tumors from patients with sepsis reveals an ethnic basis for viral infection risk and sepsis progression

Mortality from cancer-associated sepsis varies by cancer site and host responses to sepsis are heterogenous. Native Hawaiians have the highest mortality risk from cancer-associated sepsis and colorectal cancer (CRC), even though they demonstrate lower CRC incidence compared to other ethnicities. We conducted a retrospective transcriptomic analysis of CRC tumors and adjacent non-tumor tissue from adult patients of Native Hawaiian and Japanese ethnicity who died from cancer-associated sepsis. We examined differential gene expression in relation to patient survival and sepsis disease etiology. Native Hawaiian CRC patients diagnosed with sepsis had a median survival of 5 (IQR 4-49) months, compared to 117 (IQR 30-146) months for Japanese patients. Transcriptomic analyses identified two distinct sepsis gene signatures classified as early response and late response sepsis genes that were significantly altered in the Native Hawaiian cohort. Analysis of canonical pathways revealed significant up and downregulation in mechanisms of viral exit from host cells (p = 4.52E-04) and epithelial junction remodeling (p = 4.01E-05). Key genes including elongation initiation factor pathway genes, GSK3B, and regulatory associated protein of mTOR (RPTOR) genes that protect cells from infection were significantly downregulated in Native Hawaiians. Genes promoting sepsis progression including CLOCK, PPBP and Rho family GTPASE 2 (RND2) were upregulated in Native Hawaiian patients. Our transcriptomic approach advances understanding of sepsis heterogeneity by revealing a role of genetic background and defining patient subgroups with altered early and late biological responses to sepsis. This study is the first to investigate differential gene expression in CRC-associated sepsis patients in relation to ethnicity. Our findings may lead to personalized approaches in stratifying patient mortality risk for sepsis and in the development of effective targeted therapies for sepsis.

Utilization and gender disparities of Deep Brain Stimulation surgery amongst Asian Americans, Native Hawaiians, and Other Pacific Islanders with Parkinson's disease in Hawai`i

INTRODUCTION

Despite its efficacy in Parkinson's disease (PD) management, Deep Brain Stimulation (DBS) is underutilized in sociodemographic minorities. Previous investigations of racial disparities in PD aggregated Asian American (AA) and Native Hawaiian or other Pacific Islander (NHPI) populations into a single category; however, these groups have significant health differences. We sought to characterize the PD population in Hawai`i and the use of DBS among AA subgroups and NHPI patients to elucidate potential sociodemographic and clinical disparities.

METHODS

Retrospective chart review of PD patients who received DBS from 2002 to 2021 was conducted at The Queen's Medical Center on Oahu, Hawai`i. Hawai`i PD admissions from 2016 to 2020 were collected from Laulima Data Alliance database. We compared the characteristics of DBS patients, total PD admissions, and Hawai`i census data. Alpha level of < 0.05 determined statistical significance. We did a subgroup analysis of white, AA and NHPI subgroups within the patients who underwent DBS.

RESULTS

Analysis included 4215 PD admissions and 74 DBS surgeries. Compared to census data, Whites (OR: 1.67; p < 0.0001) and AA (OR: 1.18; p < 0.0001) were overrepresented in total PD admissions; whereas NHPI (OR: 0.64; p < 0.0001) and Blacks (OR: 0.17; p < 0.0001) were underrepresented. Overall, males received DBS more than females. All NHPI patients who received DBS were male, despite 37.65 % of total NHPI PD admissions being female (p = 0.0049). Most DBS patients were AA (45.95 %), followed by Whites (43.24 %), and NHPI (10.81 %).

CONCLUSIONS

NHPI and Black PD patients were disproportionately underrepresented in the Hawai`i PD population. All NHPI receiving DBS were male. These racial and gender disparities must be explored in future studies to achieve health equity and improved quality of care in a culturally sensitive manner.

Awareness of and Support for HPV Vaccination Among Pacific Islander Women in Southern California

Pacific Islander (PI) women experience disproportionately high rates of cervical cancer and mortality and have lower rates of Pap testing. Since up to 70% of cervical cancers could be prevented by being vaccinated for human papilloma virus (HPV), this cross-sectional study explored the predictors of HPV and vaccine awareness, receipt of the vaccine, and attitudes toward vaccinating children among adult PI women in southern California, who historically have low rates of HPV vaccination and high rates of cervical cancer that could be prevented with HPV vaccination. Participants (n=148) consist a subsample of Chamorro, Samoan, and Tongan women, ages 21 to 65 years, who were in a larger randomized community study to promote Pap testing. Overall, younger age and higher American acculturation were significantly associated with ever hearing about HPV and the vaccine. However, American acculturation was also associated with negative attitudes toward vaccinating their children for HPV. This paper provides preliminary insights into barriers and facilitators to HPV vaccination among PIs in the USA and also informs the development of educational programs to reduce cervical cancer incidence and mortality in this underserved population.

Risk Score Using Demographic and Clinical Risk Factors Predicts Gastric Intestinal Metaplasia Risk in a U.S. Population

BACKGROUND/AIMS

Screening for gastric intestinal metaplasia (GIM) may lead to early gastric cancer detection. We developed and validated a pre-endoscopy risk prediction model for detection of GIM based on patient-level risk factors in a U.S.

POPULATION

METHODS

We used data from 423 GIM cases and 1796 controls from a cross-sectional study among primary care and endoscopy clinic patients at the Houston VA. We developed the model using backwards stepwise regression and assessed discrimination using area under the receiver operating characteristic (AUROC). The model was internally validated using cross-validation and bootstrapping. The final expanded model was compared to a model including H. pylori infection alone and a baseline model including remaining terms without H. pylori.

RESULTS

Male sex, older age, non-white race/ethnicity, smoking status, and H. pylori were associated with GIM risk. The expanded model including these terms had AUROC 0.73 (95%CI 0.71-0.76) for predicting GIM and AUROC 0.82 (95%CI 0.79-0.86) for extensive GIM. This model discriminated better than a model including only H. pylori (AUROC 0.66; 95%CI 0.63-0.68) and the baseline model (AUROC 0.67; 95%CI 0.64-0.70). The expanded model performed similarly among primary care (AUROC 0.75) and endoscopy (AUROC 0.73) patients. The expanded model showed sufficient internal validity (cross-validation AUROC 0.72) with little evidence of over-fitting.

CONCLUSIONS

We develop and validate a non-invasive risk model for GIM detection in a U.S. population that included terms for sex, age, race/ethnicity, smoking status, and H. pylori infection. Validated risk models would identify individuals with GIM who should be referred for endoscopic screening.

Thyroid Cancer Incidence, Clinical Presentation, and Survival Among Native Hawaiian and Other Pacific Islanders

OBJECTIVE

To assess the incidence, clinical presentation, and survival in Native Hawaiian and other Pacific Islander (NHPI) patients with well-differentiated thyroid cancer.

STUDY DESIGN

This population-based incidence analysis and retrospective cohort study utilized data from the Surveillance, Epidemiology, and End Results database.

SETTING

Incidence analysis included patients diagnosed between 1990 and 2014, while the cohort to study clinical presentation and survival comprised patients diagnosed between 2004 and 2015.

METHODS

Incidence rates and trends were compared among NHPI, Asian, and non-Hispanic White (NHW) populations. Clinical presentation was assessed via multivariable logistic regression. Survival was assessed per Cox regression.

RESULTS

Recent incidence trends (2009-2014) show that the rate of increase remained consistent among NHPI patients (annual percentage change, 3.67%; 95% CI, 2.66%-4.69%), while it slowed in the NHW population and plateaued among Asians as compared with previous years. NHPI patients were more likely to present with distant metastasis than NHW patients (odds ratio, 3.37; 95% CI, 1.97-5.36) and Asian patients (odds ratio, 1.82; 95% CI, 1.05-2.97). NHPI race was also associated with advanced T stage and nodal metastasis as compared with the NHW race. Survival outcomes were similar among NHPI, NHW, and Asian patients.

CONCLUSION

Well-differentiated thyroid cancer incidence has increased at a higher rate for the NHPI population as opposed to the NHW and Asian populations in recent years. NHPI patients are more likely to present with advanced disease when compared with NHW and Asian patients. These results highlight the importance of disaggregating the often-combined Asian/Pacific Islander group in epidemiologic studies.

Head and Neck Cancer Stage at Presentation and Survival Outcomes Among Native Hawaiian and Other Pacific Islander Patients Compared With Asian and White Patients

Importance

Research studies often group Native Hawaiian and Other Pacific Islander individuals together with Asian individuals despite being consistently identified as having worse health outcomes and higher rates of comorbidities and mortality. Native Hawaiian and Other Pacific Islander individuals also have high incidence rates of oral cavity and pharyngeal cancer compared with the general population; however, disparities in clinical presentation and survival outcomes of head and neck cancer squamous cell carcinoma (HNSCC) among this population have not been investigated nor compared with those of other races.

Objective

To determine the association of race with cancer stage at diagnosis and survival outcomes among Native Hawaiian and Other Pacific Islander patients with HNSCC compared with Asian and non-Hispanic White patients.

Design, Setting, and Participants

This was a retrospective population-based cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) 18 database. Asian, Native Hawaiian or Other Pacific Islander, and non-Hispanic White adult patients diagnosed in 1988 through 2015 with HNSCC of the oral cavity, oropharynx, nasopharynx, larynx, and hypopharynx were included; any patient whose record was missing data on disease or demographic information was excluded.

Main Outcomes and Measures

Cancer stage at presentation was compared among Asian, Native Hawaiian and Other Pacific Islander, and non-Hispanic White patients using a multivariable logistic regression model. Survival outcomes were compared among these racial groups using Cox regression models. Data analyses were performed from July 1, 2021, to March 20, 2022.

Results

The total study population comprised 76 473 patients: 4894 Asian (mean [SD] age at presentation, 60.7 [14.6] years), 469 Native Hawaiian and Other Pacific Islander (57.8 [12.3] years), and 71 110 non-Hispanic White (62.2 [12.1] years) individuals. Native Hawaiian and Other Pacific Islander patients were more likely to present with advanced-stage HNSCC (odds ratio [OR], 1.38; 95% CI, 1.12 -1.72) compared with non-Hispanic White patients. Asian patients presented with similar stage disease (OR, 1.04; 95% CI, 0.97-1.11) compared with non-Hispanic White patients. Native Hawaiian and Other Pacific Islander patients had worse disease-specific survival (HR, 1.18; 95% CI, 1.02-1.36) compared with non-Hispanic White patients after adjusting for clinical and demographic factors. In contrast, Asian patients had improved disease-specific survival (HR, 0.93; 95% CI, 0.88-0.98) compared with non-Hispanic White patients.

Conclusions and Relevance

This retrospective population-based cohort study suggests that Native Hawaiian and Other Pacific Islander race was associated with more advanced HNSCC, and worse disease-specific survival compared with non-Hispanic White race, while Asian race was associated with improved survival. This study highlights the importance of disaggregating Asian from Pacific Islander data when assessing health disparities, and the need for culturally sensitive interventions to promote earlier detection of head and neck cancer and improved survival among the Native Hawaiian and Other Pacific Islander population.

Charting a Path Towards Asian American Cancer Health Equity: A Way Forward

On July 29, 2021, the US Food and Drug Administration's Oncology Center of Excellence convened Conversations on Cancer. This Conversation, the first ever by the US Food and Drug Administration, focused on Asian Americans and served as the platform for this Commentary. Panelists elaborated on topics ranging from heterogeneity in Asian American demographics to racism through a path to health equity and supplemented this Commentary with literature citations. Asian Americans are the fastest-growing US race group, yet data aggregation obscures distinctions and cancer disparities within the more than 24 million Asians living in the United States with harmful impacts on communities and patients, as illustrated by breast cancer survivor Susan Shinagawa's patient-to-advocate journey. Bigotry against Asian Americans has been pervasive since the 19th century, but especially during the COVID-19 pandemic. Asian Americans are unique as the first US population to experience cancer as the leading cause of death. Asian Americans are disproportionately affected by cancers because of infectious origins and have the highest rates of lung cancer among never-smoking women. The infinitesimal proportion of the National Institutes of Health's budget compared with experiencing the highest percentage increases of any US racial population more than 3 decades highlights the dearth of focused research among Asian Americans. Recognizing the heterogeneity of Asian Americans and that disaggregated data are critical for accurately characterizing distinct ethnic groups, focusing on the impact of racism and COVID-19 on cancer disparities, and focusing and prioritizing funding resources are necessary steps forward for achieving health equity for Asian Americans.

Just data representation for Native Hawaiians and Pacific Islanders: A critical review of systemic Indigenous erasure in census and recommendations for psychologists

The decennial Census survey marks the emergence of federal classifications of race and ethnicity by which the U.S. government has historically conflated Native Hawaiians and Pacific Islanders (NHPI, hereafter) as "Asian or Pacific Islander." This conflation amplifies health injustices and inequities of NHPIs through multiple mechanisms because it masks the complex and heterogeneous experiences of NHPIs, whose positions and relations with the settler state are qualitatively and substantially distinct from Asian Americans. This critical review examines federal documents and research to examine how the panethnic categorizations are often sustained through scientific inquiry and methodologies. We found that self-determination and self-identification for NHPIs are impeded by settler-colonial relations between U.S. colonization of parts of Oceania (e.g., Hawai'i, Sāmoa, Fiji, and Guam) and the forcefully imposed categorization that continues to be in use to legitimize the domination of Indigenous Peoples through race misclassification. Specifically, Census data collection fails to capture accurate and reliable data due to serious methodological limitations. These implications for psychological research compel us to make several recommendations for psychologists: (1) engage with NHPI community partners in all research processes; (2) critically examine Census research design and consider oversampling NHPI households to ensure just data representation; (3) meaningfully engage when, whether and how to aggregate Asian Americans with NHPIs; and (4) use Indigeneity as a critical framework.

Elevated breast cancer mortality among highly educated Asian American women

Background

Postmenopausal breast cancer (PMBC) is the most commonly diagnosed and the second leading cause of cancer death among women in the US. Research examining the association between PMBC and education level has been inconsistent; no study in the US has examined how educational level impacts PMBC mortality in Asian American women, a largely immigrant population with above-average educational attainment.

Methods

California Vital Statistics data from 2012–2017 were analyzed to derive age-adjusted mortality rate ratios (MRRs) by education level (associates degree or above referred to as “higher education”, high school, less than high school) and race [Non-Hispanic White (NHW), Asian/Pacific Islander (Asian), and its two largest subpopulations: Chinese and Filipino] from negative binomial regression models.

Results

PMBC mortality for both NHWs and Asians was greater among women with higher education compared to those who did not complete high school: NHWs had 22% higher PMBC mortality (MRR 1.22; 95% CI: 1.14–1.31) and Asians had 2.6 times greater PMBC mortality (MRR 2.64; 95% CI: 2.32–3.00) than their counterparts who did not complete high school. Asians in the lowest education level had 70% lower mortality than NHWs (MRR 0.30; 95% CI: 0.27–0.34). This mortality advantage among Asians was greatly reduced to only 27% lower among the highest educated (MRR 0.73; 95% CI: 0.68–0.78). For higher educated Filipina women, no mortality advantage was evident compared to NHWs (MRR 0.96; 95% CI: 0.88–1.05).

Conclusion

PMBC mortality for higher educated Asian women is elevated in comparison to their counterparts with less education. Given that PMBC survival is greater among those with higher education, our findings strongly suggest an excess in the incidence of PMBC (more than double) among higher educated Asian women; this warrants more research into potentially modifiable causes of PMBC in this burgeoning population.

Race/Ethnicity and Birthplace as Risk Factors for Gastric Intestinal Metaplasia in a Multiethnic United States Population

INTRODUCTION

Several US subgroups have increased risk of gastric cancer and gastric intestinal metaplasia (GIM) and may benefit from targeted screening. We evaluated demographic and clinical risk factors for GIM and examined the interaction between race/ethnicity and birthplace on GIM risk.

METHODS

We identified patients who had undergone esophagogastroduodenoscopy with gastric biopsy from 3/2006-11/2016 using the pathology database at a safety net hospital in Houston, Texas. Cases had GIM on ≥1 gastric biopsy histopathology, whereas controls lacked GIM on any biopsy. We estimated odds ratios and 95% confidence intervals (CI) for associations with GIM risk using logistic regression and developed a risk prediction model of GIM risk. We additionally examined for associations using a composite variable combining race/ethnicity and birthplace.

RESULTS

Among 267 cases with GIM and 1,842 controls, older age (vs <40 years: 40-60 years adjusted odds ratios (adjORs) 2.02; 95% CI 1.17-3.29; >60 years adjOR 4.58; 95% CI 2.61-8.03), Black race (vs non-Hispanic White: adjOR 2.17; 95% CI 1.31-3.62), Asian race (adjOR 2.83; 95% CI 1.27-6.29), and current smoking status (adjOR 2.04; 95% CI 1.39-3.00) were independently associated with increased GIM risk. Although non-US-born Hispanics had higher risk of GIM (vs non-Hispanic White: adjOR 2.10; 95% CI 1.28-3.45), we found no elevated risk for US-born Hispanics (adjOR 1.13; 95% CI 0.57-2.23). The risk prediction model had area under the receiver operating characteristic of 0.673 (95% CI 0.636-0.710) for discriminating GIM.

DISCUSSION

We found that Hispanics born outside the United States were at increased risk of GIM, whereas Hispanics born in the United States were not, independent of Helicobacter pylori infection. Birthplace may be more informative than race/ethnicity when determining GIM risk among US populations.

Disparities in clinical and demographic characteristics among Asian/Pacific Islander and Non-Hispanic White newly diagnosed lung cancer patients

PURPOSE

Racial disparities persist among lung cancer patients but have not been adequately studied among Asian/Pacific Islander (API) subgroups, which are heterogeneous. This study compared clinical and demographic characteristics at diagnosis of API subgroups and NHW patients.

METHODS

NHW and API adults diagnosed with lung cancer were identified from the Surveillance, Epidemiology, and End Results database (1990-2015). API was divided into eight subgroups: Chinese, Japanese, Filipino, Hawaiian/Pacific Islander, Korean, Vietnamese, Asian Indian/Pakistani, and Other. Multivariable multinomial logistic regression models were used to assess adjusted associations of clinical and demographic factors with API/subgroups.

RESULTS

There were 522,702 (92.6%) NHW and 41,479 (7.4%) API lung cancer patients. API were less likely to be diagnosed at the age of ≥ 80 years (OR_adj 0.53, 95% CI 0.48-0.58 for ≥ 80 vs. ≤ 39 years) than NHW. However, Japanese patients were more often diagnosed at ≥ 80 years compared to other ethnic subgroups. API were less often female (OR_adj 0.85, 95% CI 0.83-0.86), and unmarried (OR_adj 0.71, 95% CI 0.68-0.74); however, among API, Japanese, Hawaiian/Pacific Islander, Korean, and Vietnamese were more often unmarried, compared to Chinese patients. API were more frequently diagnosed at stage IV, compared to stage I (OR_adj 1.31, 95% CI 1.27-1.35). API had significantly less squamous cell carcinoma (OR_adj 0.54, 95% CI 0.52-0.56, compared to adenocarcinoma); among API, Japanese, Filipino, Hawaiian/Pacific Islander, Korean, Asian Indian/Pakistani, and Other were more likely than Chinese patients to present with squamous cell histology (range: OR_adj[Other] 1.24, 95% CI 1.09-1.41; OR_adj[Hawaiian/Pacific Islander] 2.47, 95% CI 2.22-2.75).

CONCLUSION

At diagnosis, there are significant differences in demographic and clinical characteristics between NHW, API, and API subgroups. Treating API patients as a single population may overlook biological, environmental, and behavioral differences that might be beneficial in designing prevention strategies and treatment.

Incidence of breast cancer subtypes in immigrant and non-immigrant women in Norway

BACKGROUND

Breast cancer incidence differs between non-immigrants and immigrants from low- and middle-income countries. This study investigates whether immigrants also have different subtype-specific incidences.

METHODS

We used national health registries in Norway and calculated subtype-specific incidence rate ratios (IRRs) for invasive breast cancer among women aged 20-75 and 20-49 years between 2005 and 2015. Immigrant groups were classified by country of birth broadly defined based on WHO regional groupings. Subtype was defined using estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor 2 (HER2) status as luminal A-like (ER+ PR+ HER2-), luminal B-like/HER2- (ER+ PR- HER2-), luminal B-like/HER2+ (ER+ PR any HER2+), HER2+ (ER-PR-HER2+) and triple-negative breast cancer (TNBC) (ER-PR-HER2-).

RESULTS

Compared to non-immigrants, incidence of the luminal A-like subtype was lower in immigrants from Sub-Saharan Africa (IRR 0.43 95% CI 0.28-0.66), South East Asia (IRR 0.63 95% CI 0.51-0.79), South Asia (IRR 0.67 95% CI 0.52-0.86) and Eastern Europe (IRR 0.86 95% CI 0.76-0.99). Immigrants from South Asia had higher rates of HER2 + tumors (IRR 2.02 95% CI 1.26-3.23). The rates of TNBC tended to be similar regardless of region of birth, except that women from South East Asia had an IRR of 0.54 (95% CI 0.32-0.91).

CONCLUSIONS

Women from Eastern Europe, Sub-Saharan Africa and Asia had different subtype-specific incidences compared to women from high-income countries (including non-immigrants). These differences in tumor characteristics between immigrant groups should be taken into consideration when planning preventive or screening strategies.

Food insecurity and chronic diseases among Native Hawaiians and Pacific Islanders in the US: results of a population-based survey

Data from the 2014 Native Hawaiian and Pacific Islander (NHPI) National Health Interview Survey were used to examine associations between food security and individual chronic diseases, total number of chronic diseases, and general health status among 637 NHPI adults with income below 200 percent federal poverty level. Very low food security was associated with hypertension, diabetes, and asthma. Very low food security and marginal food security were associated with having any chronic disease and with having a higher number of chronic diseases. Risk for food insecurity increased as health status decreased. These associations had not previously been documented for NHPI.

Association of Race and Ethnicity With Prostate Cancer-Specific Mortality in Canada

This cohort study uses data from the Canadian Census Health and Environment Cohorts to assess the association of race and ethnicity with prostate cancer–specific mortality among men in Canada.

Thyroid cancer incidence disparities among ethnic Asian American populations, 1990-2014

PURPOSE

Asian/Pacific Islanders (APIs) are at high risk of thyroid cancer, hence we examined thyroid cancer's incidence among disaggregated API subgroups in the United States (U.S.) to identify potential ethnic-specific disparities.

METHODS

Data from 1990 to 2014 in the Surveillance, Epidemiology, and End Results Program (SEER) were used to compare age-adjusted incidence rates (AAIRs) of thyroid cancer for seven API ethnic subgroups to non-Hispanic whites (NHWs) using incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Sex, age, tumor histotype, and year of diagnosis were considered. Trends were evaluated using average annual percent change (AAPC) statistics.

RESULTS

The highest AAIRs (per 100,000 person-years) were among Filipinos (female AAIR=20.49, male AAIR=7.06) and the lowest among Japanese (female AAIR=8.36, male AAIR=3.20). However, Filipinos showed significantly lower incidence of medullary tumors when compared to NHWs (female IRR=0.60, 95% CI 0.40-0.87, male IRR=0.26, 95% CI 0.26-0.51). The largest increasing trends were among Asian Indian/Pakistanis for females (AAPC=5.19, 95% CI 3.81 to 6.58) and Koreans for males (AAPC=4.57, 95% CI 3.14 to 6.03).

CONCLUSIONS

There are clear differences in thyroid cancer incidence and trends when U.S. API ethnic subgroups are examined separately. Disaggregating APIs in research can provide critical information for understanding thyroid cancer risk.

Examining the relationship between self-reported lifetime cancer diagnosis and nativity: findings from the National Health and Nutrition Examination Survey (NHANES) 2011-2018

PURPOSE

Cancer incidence in the USA remains higher among certain groups, regions, and communities, and there are variations based on nativity. Research has primarily focused on specific groups and types of cancer. This study expands on previous studies to explore the relationship between country of birth (nativity) and all cancer site incidences among USA and foreign-born residents using a nationally representative sample.

METHODS

This is a cross-sectional study of (unweighted n = 22,554; weighted n = 231,175,933) participants between the ages of 20 and 80 from the National Health and Nutrition Examination Survey (NHANES) 2011-2018. Using weighted logistic regressions, we analyzed the impact of nativity on self-reported cancer diagnosis controlling for routine care, smoking status, overweight, race/ethnicity, age, and gender. We ran a partial model, adjusting only for age as a covariate, a full model with all other covariates, and stratified by race/ethnicity.

RESULTS

In the partial and full models, our findings indicate that US-born individuals were more likely to report a cancer diagnosis compared to their foreign-born counterparts (OR 2.34, 95% CI [1.93; 2.84], p < 0.01) and (OR 1. 39, 95% CI [1.05; 1.84], p < 0.05), respectively. This significance persisted only among non-Hispanic Blacks when stratified by race. Non-Hispanic Blacks who were US-born were more likely to report a cancer diagnosis compared to their foreign-born counterparts (OR 2.30, 95% [CI 1.31; 4.02], p < 0.05).

CONCLUSION

A variety of factors may reflect lower self-reported cancer diagnosis in foreign-born individuals in the USA other than a healthy immigrant advantage. Future studies should consider the factors behind the differences in cancer diagnoses based on nativity status, particularly among non-Hispanic Blacks.

Racial and Ethnic Disparities in Rates of Invasive Second Breast Cancer Among Women With Ductal Carcinoma In Situ in Hawai'i

Importance

Women with ductal carcinoma in situ (DCIS) may develop a subsequent invasive second breast cancer (SBC). Understanding the association of racial and ethnic factors with the development of invasive SBC may help reduce overtreatment and undertreatment of women from minority groups.

Objective

To evaluate risk factors associated with developing invasive ipsilateral SBC (iiSBC) and invasive contralateral SBC (icSBC) among women with an initial diagnosis of DCIS who are from racial and ethnic minority populations.

Design, Setting, and Participants

This retrospective cohort study used deidentified data from the Hawai'i Tumor Registry of 6221 female Hawai'i residents aged 20 years or older who received a diagnosis of DCIS between January 1, 1973, and December 31, 2017. The 5 most populous ethnic groups were compared (Chinese, Filipino, Japanese, Native Hawaiian, and White). Data analysis was performed from 2020 to 2021.

Exposures

Patient demographic and clinical characteristics and the first course of treatment.

Main Outcome and Measures

The a priori study outcome was the development of invasive SBC. Logistic regression was used to identify factors associated with invasive SBC. Factors that were significant on unadjusted analyses were included in the adjusted models (ie, age, race and ethnicity, diagnosis year, DCIS histologic characteristics, laterality, hormone status, and treatment).

Results

The racial and ethnic distribution of patients with DCIS across the state's most populous groups were 2270 Japanese women (37%), 1411 White women (23%), 840 Filipino women (14%), 821 Native Hawaiian women (13%), and 491 Chinese women (8%). Women of other minority race and ethnicity collectively comprised 6% of cases (n = 388). A total of 6221 women (age range, 20 to ≥80 years) were included in the study; 4817 (77%) were 50 years of age or older, 4452 (72%) received a diagnosis between 2000 and 2017, 2581 (42%) had well or moderately differentiated histologic characteristics, 2383 (38%) had noninfiltrating intraductal DCIS, and 2011 (32%) were treated with mastectomy only. Of these 6221 women, 444 (7%) developed invasive SBC; 190 developed iiSBC (median time to SBC diagnosis, 7.8 years [range, 0.5-30 years]) and 254 developed icSBC (median time to SBC diagnosis, 5.9 years [range, 0.5-28.8 years]). On adjusted analysis, women who developed iiSBC were more likely to be younger than 50 years (adjusted odds ratio [aOR], 1.49; 95% CI, 1.08-2.06), Native Hawaiian (aOR, 3.28; 95% CI, 2.01-5.35), Filipino (aOR, 1.94; 95% CI, 1.11-3.42), Japanese (aOR, 1.58; 95% CI, 1.01-2.48), and untreated (aOR, 2.29; 95% CI, 1.09-4.80). Compared with breast-conserving surgery (BCS) alone, there was a decreased likelihood of iiSBC among women receiving BCS and radiotherapy (aOR, 0.45; 95% CI, 0.27-0.75), BCS and systemic treatment with or without radiotherapy (aOR, 0.40; 95% CI, 0.23-0.69), mastectomy only (aOR, 0.23; 95% CI, 0.13-0.39), and mastectomy and systemic treatment (aOR, 0.57; 95% CI, 0.33-0.96). Women who developed an icSBC were more likely to be Native Hawaiian (aOR, 1.69; 95% CI, 1.10-2.61) or Filipino (aOR, 1.70; 95% CI, 1.10-2.63). Risk of both iiSBC and icSBC decreased in the later years of diagnosis (2000-2017) compared with the earlier years (1973-1999).

Conclusions and Relevance

This study suggests that Native Hawaiian and Filipino women who initially received a diagnosis of DCIS were more likely to subsequently develop both iiSBC and icSBC. Japanese women and younger women were more likely to develop iiSBC. Subpopulation disaggregation may help guide clinical treatment and screening decisions for at-risk subpopulations.

Impact of COVID-19 on cervical cancer screening: Challenges and opportunities to improving resilience and reduce disparities

The COVID-19 pandemic has a major impact on a wide range of health outcomes. Disruptions of elective health services related to cervical screening, management of abnormal screening test results, and treatment of precancers, may lead to increases in cervical cancer incidence and exacerbate existing health disparities. Modeling studies suggest that a short delay of cervical screening in subjects with previously negative HPV results has minor effects on cancer outcomes, while delay of management and treatment can lead to larger increases in cervical cancer. Several approaches can mitigate the effects of disruption of cervical screening and management. HPV-based screening has higher accuracy compared to cytology, and a negative HPV result provides longer reassurance against cervical cancer; further, HPV testing can be conducted from self-collected specimens. Self-collection expands the reach of screening to underserved populations who currently do not participate in screening. Self-collection and can also provide alternative screening approaches during the pandemic because testing can be supported by telehealth and specimens collected in the home, substantially reducing patient-provider contact and risk of COVID-19 exposure, and also expanding the reach of catch-up services to address backlogs of screening tests that accumulated during the pandemic. Risk-based management allows prioritizing management of patients at highest risk of cervical cancer while extending screening intervals for those at lowest risk. The pandemic provides important lessons for how to make cervical screening more resilient to disruptions and how to reduce cervical cancer disparities that may be exacerbated due to disruptions of health services.

Communication Among Southeast Asian Mothers and Daughters About Cervical Cancer Prevention

BACKGROUND

Southeast Asian women have high rates of cervical cancer and yet are among the least likely to be screened. There is sparse literature on communication patterns among Southeast Asian women, specifically related to cervical cancer and Pap test uptake. Little is known about the influence of Southeast Asian mothers and daughters on each other's cervical cancer beliefs and screening behaviors.

OBJECTIVES

We examined the perceptions of and barriers to cervical cancer screening among Cambodian and Lao mothers and daughters and explored how they converse about women's health issues, specifically cervical cancer and Pap testing.

METHODS

We conducted in-depth interviews with Cambodian and Lao mother-daughter dyads, aged 18 years and older, living in a large Midwestern city between February and September of 2015. Descriptive statistics were calculated to summarize the sample demographic characteristics. Bivariate tests (contingency table analyses, independent t-tests, and Pearson correlations) were conducted to test for differences between the mothers and daughters in demographic characteristics and measures of health status and beliefs. Qualitative data were analyzed using content analysis.

RESULTS

In-depth interviews were conducted with three Cambodian and eight Lao mother-daughter dyads. The daughters were significantly more acculturated to English, had greater education, and were mostly employed full time. The mothers and daughters evaluated their health status much the same, their medical mistrust equally, and all of the mothers and nine of the daughters were Buddhist. Themes in mother-daughter communication included what mothers and daughters do and do not talk about with regard to sexual health, refugee experiences, what hinders mother-daughter communication, and relationship dynamics. The mothers were embarrassed and uncomfortable discussing cervical cancer, Pap testing, and other women's health issues with their daughters. Although mothers did not influence women's health promotion or cervical cancer prevention with their daughters, daughters did influence their mothers' health and healthcare decisions. Daughters were critical in navigating healthcare systems, engaging with providers, and making medical decisions on behalf of their mothers.

DISCUSSION

By leveraging the unique and dynamic intergenerational bond that mothers and daughters who identify as Southeast Asian have, we can develop strategies to influence the cultural dialogue related to cervical cancer and early detection.

Survivorship Care Plan Preferences and Utilization Among Asian American Breast Cancer Survivors

PROBLEM IDENTIFICATION

The survivorship care plan (SCP) is an individualized document with cancer diagnosis, treatment, surveillance, and health promotion recommendations. This integrative review synthesizes the extant literature to understand preferences and utilization of SCPs among Asian American survivors.

LITERATURE SEARCH

The CINAHL®, Embase®, PsycINFO®, and PubMed® databases were searched for articles about Asian American women with breast or cervical cancer and SCPs.

DATA EVALUATION

Two independent reviewers evaluated 481 titles and abstracts according to inclusion and exclusion criteria. Of those 481 titles and abstracts, 14 articles were selected for inclusion.

SYNTHESIS

There was little evidence surrounding utilization of SCPs. Articles identified addressed only survivors of breast cancer, predominately of Southeast Asian descent. Asian American women with breast cancer reported preferences surrounding their survivorship needs. Barriers to delivery of the SCP were related to socioeconomic factors.

IMPLICATIONS FOR RESEARCH

There is a paucity of information guiding evidence-based delivery of SCPs in the vastly heterogenous population of Asian American survivors. More work is needed to provide high-quality care to these survivors.

Anti-Asian American Racism: A Wake-Up Call for Population-Based Cancer Research

Since the start of the COVID-19 pandemic, Asian Americans have been subjected to rising overt discrimination and violent hate crimes, highlighting the health implications of racism toward Asian Americans. As Asian Americans are the only group for whom cancer is the leading cause of death, these manifestations of anti-Asian racism provoke the question of the impact of racism across the cancer continuum for Asian Americans. In this Commentary, we describe how the myth of the "model minority" overlooks the diversity of Asian Americans. Ignoring such diversity in sociocultural trends, immigration patterns, socioeconomic status, health behaviors, and barriers to care masks disparities in cancer risk, access to care, and outcomes across Asian American populations. We recommend cancer epidemiologists, population science researchers, and oncology providers direct attention toward: (i) studying the impacts of structural and personally mediated racism on cancer risk and outcomes; (ii) ensuring studies reflect the uniqueness of individual ethnic groups, including intersectionality, and uncover underlying disparities; and (iii) applying a critical race theory approach that considers the unique lived experiences of each group. A more nuanced understanding of cancer health disparities, and how drivers of these disparities are associated with race and differ across Asian American ethnicities, may elucidate means through which these disparities can be alleviated.

HPV Vaccine Initiation and Completion Among Native Hawaiian and Pacific Islander Adults, United States, 2014

Native Hawaiian and Pacific Islander (NHPI) adults bear a disproportionate burden of certain human papillomavirus (HPV)-associated cancers. In 2015, data from the National Health Interview Survey (NHIS) showed vaccination coverage among adults by racial and ethnic groups; however, coverage data for NHPI adults were unavailable. In this study, we estimated the initiation and completion of HPV vaccination and assessed the factors associated with vaccination among NHPI adults aged 18 to 26 years in the United States. We analyzed public data files from the 2014 NHPI NHIS (n = 1204). We specified sampling design parameters and fitted weighted logistic regression models to calculate the odds of HPV vaccine initiation. We developed a directed acyclic graph to identify a minimally sufficient set for adjustment and adjusted for insurance coverage (for education and ethnicity) and doctor visit (for insurance coverage, earnings, ethnicity, and sex). Overall, 24.9% and 11.5% of NHPI adults had initiated and completed the HPV vaccination series, respectively. Weighted logistic regression models elucidated that the odds of HPV vaccine initiation were higher for females (weighted odds ratio = 5.4; 95% confidence interval = 2.8-10.4) compared with males. Low vaccination coverage found among NHPI adults provides an opportunity for targeted programs to reduce the burden of HPV-associated cancers.

Cancer Mortality Disparities among Asian American and Native Hawaiian/Pacific Islander Populations in California

BACKGROUND

Asian American and Native Hawaiian/Pacific Islanders (AANHPI) are the fastest growing minority in the United States. Cancer is the leading cause of death for AANHPIs, despite relatively lower cancer morbidity and mortality. Their recent demographic growth facilitates a detailed identification of AANHPI populations with higher cancer risk.

METHODS

Age-adjusted, sex-stratified, site-specific cancer mortality rates from California for 2012 to 2017 were computed for AANHPI groups: Chinese, Filipino, South Asian, Vietnamese, Korean, Japanese, Southeast Asian (i.e., Cambodian, Hmong, Laotian, Thai), and Native Hawaiian and Other Pacific Islander (NHOPI). Regression-derived mortality rate ratios (MRR) were used to compare each AANHPI group to non-Hispanic whites (NHW).

RESULTS

AANHPI men and women (total 40,740 deaths) had lower all-sites-combined cancer mortality rates (128.3 and 92.4 per 100,000, respectively) than NHWs (185.3 and 140.6) but higher mortality for nasopharynx, stomach, and liver cancers. Among AANHPIs, both NHOPIs and Southeast Asians had the highest overall rates including for colorectal, lung (men only), and cervical cancers; South Asians had the lowest. NHOPI women had 41% higher overall mortality than NHWs (MRR = 1.41; 95% CI, 1.25-1.58), including for breast (MRR = 1.33; 95% CI, 1.08-1.65) and markedly higher for endometrial cancer (MRR = 3.34; 95% CI, 2.53-4.42).

CONCLUSIONS

AANHPI populations present with considerable heterogeneous cancer mortality patterns. Heightened mortality for infection, obesity, and tobacco-related cancers in Southeast Asians and NHOPI populations highlight the need for differentiated priorities and public health interventions among specific AANHPI populations.

IMPACT

Not all AANHPIs have favorable cancer profiles. It is imperative to expand the focus on the currently understudied populations that bear a disproportionate cancer burden.

Current Gaps in Breast Cancer Screening Among Asian and Asian American Women in the United States

Over the past two decades, the US Asian population has increased 72%, representing the fastest growth rate of any major racial group. Currently, there are over 20 million Asian and Asian American women in the United States, who identify with at least 1 of 19 different origin groups. Although women of Asian ancestry have traditionally been considered low risk for experiencing adverse breast cancer-specific outcomes, aggregated data may mask health disparities seen among subgroups. In the United States, recent data demonstrate that the burden of breast cancer among Asian women has increased each year over the past decade. We aim to characterize challenges faced by Asian and Asian American women in the United States related to cultural stigma, socioeconomic status, and overall access to breast cancer care. An increased understanding of barriers to breast cancer prevention and treatment efforts is needed to develop more effective strategies aimed at reducing disparities in care among segments of this heterogenous population.

Regulation of TREM1-Mediated Inflammation in Hepatocellular Carcinoma Cells

Hepatocellular carcinoma (HCC), accounting for more than 90% of cases of primary liver cancer, is the third most common cause of cancer-related death worldwide. Chronic inflammation precedes the development of cirrhosis and HCC. TREM (triggering receptor expressed on myeloid cell)-1 is an inflammatory marker and amplifier of inflammation that signals through PI3K and ERK1/2 to activate transcription factors, resulting in increased secretion of pro-inflammatory cytokines, causing chronic inflammation and predisposing the liver to carcinogenesis. Thus, targeting TREM-1 in HCC might be a potential therapeutic target. A low level of vitamin D has been associated with chronic inflammation and poor prognosis in HCC. Thus, we evaluated the effect of vitamin D on TREM-1 expression in the HCC cell line. Additionally, the effects of high mobility group box-1, lipopolysaccharide, and transcription factor PU.1 on the expression of TREM-1 in normal liver cells and HCC cells have been investigated in the presence and absence of vitamin D. The results showed increased expression of TREM-1 in HCC cells and with IL-6, TNF-α, LPS, and rHMGB-1 and decreased expression with calcitriol. Calcitriol also attenuated the effect of IL-6, TNF-α, LPS, and rHMGB-1 on TREM-1. Calcitriol treatment attenuated the proliferation, migration, and invasion of HCC cells. These results (in vitro) provide molecular and biochemical evidence that calcitriol significantly attenuates the expression of mediators of inflammation, and thus might be used therapeutically together with conventional treatment to delay the progression of HCC. Additionally, the negative regulation of TREM-1 by PU.1 suggests PU.1 as a potential therapeutic target.

The Validity of MotionSense HRV in Estimating Sedentary Behavior and Physical Activity under Free-Living and Simulated Activity Settings

MotionSense HRV is a wrist-worn accelerometery-based sensor that is paired with a smartphone and is thus capable of measuring the intensity, duration, and frequency of physical activity (PA). However, little information is available on the validity of the MotionSense HRV. Therefore, the purpose of this study was to assess the concurrent validity of the MotionSense HRV in estimating sedentary behavior (SED) and PA. A total of 20 healthy adults (age: 32.5 ± 15.1 years) wore the MotionSense HRV and ActiGraph GT9X accelerometer (GT9X) on their non-dominant wrist for seven consecutive days during free-living conditions. Raw acceleration data from the devices were summarized into average time (min/day) spent in SED and moderate-to-vigorous PA (MVPA). Additionally, using the Cosemed K5 indirect calorimetry system (K5) as a criterion measure, the validity of the MotionSense HRV was examined in simulated free-living conditions. Pearson correlations, mean absolute percent errors (MAPE), Bland–Altman (BA) plots, and equivalence tests were used to examine the validity of the MotionSense HRV against criterion measures. The correlations between the MotionSense HRV and GT9X were high and the MAPE were low for both the SED (r = 0.99, MAPE = 2.4%) and MVPA (r = 0.97, MAPE = 9.1%) estimates under free-living conditions. BA plots illustrated that there was no systematic bias between the MotionSense HRV and criterion measures. The estimates of SED and MVPA from the MotionSense HRV were significantly equivalent to those from the GT9X; the equivalence zones were set at 16.5% for SED and 29% for MVPA. The estimates of SED and PA from the MotionSense HRV were less comparable when compared with those from the K5. The MotionSense HRV yielded comparable estimates for SED and PA when compared with the GT9X accelerometer under free-living conditions. We confirmed the promising application of the MotionSense HRV for monitoring PA patterns for practical and research purposes.

Implications of Withaferin-A for triple-negative breast cancer chemoprevention

Triple-negative breast cancer (TNBC) accounts for about 15 % of all breast cancer cases, and unlike other malignancies, it lacks definite prognostic markers. While improved survival responses have been documented with the ongoing therapeutic approaches, the development of tumor resistance mechanisms to these treatment options pose major challenges in the treatment of TNBC. Notably, naturally occurring medicinal compounds have been studied extensively for their anti-neoplastic activities in cancer models including breast cancer due to their safe and non-deleterious effects. Among various dietary compounds, Withaferin-A (WA), a phytochemical derived from an ayurvedic medicinal plant, Withania somnifera has been characterized to possess anti-inflammatory and anti-cancer properties. Importantly, multiple studies have shown that WA exhibits promising anti-tumoral activities against in-vitro and in-vivo experimental models of TNBC and that its combination has been documented to enhance chemotherapy efficacy. The current review highlights the mechanistic insights with recent updates including the pharmacokinetics parameters and implications of WA against breast cancer with major emphasis on TNBC.

Evaluation of access to care issues in patients with breast cancer

AIMS

System-level efforts have been deployed to improve oncology care and access while reducing utilization and costs. Understanding the nature of access to care from the perspective of patients themselves is an unmet need. This study examined access to care in a population of women with breast cancer and its relationship to overall patient satisfaction.

MATERIALS AND METHODS

Patients with breast cancer from six oncology clinics in five states completed a survey during routine office visits. Access to care (higher scores indicated increasing access barriers), overall patient satisfaction, and patient demographic/clinical characteristics were measured. The relationships between access (composite and factor scores) and satisfaction were assessed using multivariable analyses controlling for age (the only significant characteristic from bivariate analyses).

RESULTS

A total of 180 patients completed the survey. Factor analysis of access to care items revealed an 8-factor measure - Insurance, Health System, Emotional, Holistic Treatment, Family Support, Knowledge/Understanding, Information Quality, and Financial Support - with high reliability (Composite: Cronbach alpha = 0.93; Factors: Cronbach alpha range = 0.85-0.91). Access composite score was moderately low (mean = 1.90), indicating an overall low level of access barriers, and overall patient satisfaction was high (mean = 4.59). The composite score (p < .001) and the Health System and Knowledge/Understanding factors (p < .01) were significant and negative predictors of overall satisfaction.

LIMITATIONS

Study sites were high functioning clinics and all, but one, are Oncology Care Model practices. Thus, the scope of access to care issues for patients of under-resourced clinics might not be well addressed.

CONCLUSIONS

Access to care overall and by factor was significantly predictive of patient satisfaction with care. In addition, access to care factors varied across several demographic and clinical characteristics. Future strategies that address access to care challenges should consider these modifiable, patient-centric, and system-based issues.
