Abstract
INTRODUCTION California is home to the largest population of Armenians in the United States. The historical categorization of Armenians as 'White' or 'Some Other Race' in population databases has likely masked cancer incidence patterns in this population. This is the first study considering cancer incidence among Armenians in California. METHODS We used the Armenian Surname List and birthplace information in the California Cancer Registry to identify Armenians with cancer diagnosed during 1988-2019. We calculated proportional incidence ratios (PIR) among Armenians compared with non-Hispanic Whites (NHWs). As an exploratory analysis, we calculated incidence rate ratios (IRR) during 2006-2015 using Armenian population denominators from the American Community Survey (ACS). We selected PIR as our primary method given uncertainty regarding the use of ACS population estimates for rate calculations. RESULTS There were 27,212 cancer diagnoses among Armenians in California, 13,754 among males and 13,458 among females. Armenian males had notably higher proportions of stomach (PIR = 2.39), thyroid (PIR = 1.45), and tobacco-related cancers including bladder (PIR = 1.53), colorectal (PIR = 1.29), and lung (PIR = 1.16) cancers. Higher proportional incidence of cancers including stomach (PIR = 3.24), thyroid (PIR = 1.47), and colorectal (PIR = 1.29) were observed among Armenian females. Exploratory IRR analyses showed higher stomach (IRR = 1.78), bladder (IRR = 1.13), and colorectal (IRR = 1.12) cancers among Armenian males and higher stomach (IRR = 2.54) cancer among Armenian females. CONCLUSION We observed higher stomach, colorectal and thyroid cancer incidence among males and females, and tobacco-related cancers among males. Further research is needed to refine Armenian population estimates and understand and address risk factors associated with specific cancers among Armenians in California.

Abstract
BACKGROUND There are an estimated 460,000 Armenians in the United States, and more than half live in California. Armenian-Americans are generally represented within the 'White' or 'Some Other Race' race categories in population-based research studies. While Armenians have been included in studies focused on Middle-Eastern populations, there are no studies focused exclusively on Armenians due to a lack of standardized collection of Armenian ethnicity in the United States or an Armenian surname list. To fill this research gap, we sought to construct and evaluate an Armenian Surname List (ASL) for use as an identification tool in public health and epidemiological research studies focused on Armenian populations. METHODS Data sources for the ASL included the California Public Use Death Files (CPUDF) and the Middle Eastern Surname List (MESL). For evaluation of the ASL, the California Cancer Registry (CCR) database was queried for surnames with birthplace in Armenia and identified by the MESL. RESULTS There are a total of 3,428 surnames in the ASL. Nearly half (1,678) of surnames in the ASL were not identified by the MESL. The ASL captured 310 additional Armenian surnames in the CCR than the MESL. CONCLUSIONS The ASL is the first surname list for identifying Armenians in major databases for epidemiological research.

Abstract
BACKGROUND The authors compared proportions and associations of depression screening, major depression, and follow-up care of Arab Americans compared to non-Hispanic whites, non-Hispanic blacks, Asians, and Hispanics. METHODS Administrative data was electronically abstracted from a large health system in metropolitan Detroit among 97,918 adult patients in 2014 and 2015. A valid and reliable surname list was used to identify Arab Americans. Using chi-squares, we examined the relationship between race/ethnicity and depression screening, major depression, and follow-up care. We calculated odds ratios (OR) and 95% confidence intervals (CI) to examine the relationship between the main independent variable of race/ethnicity and the dependent variables of depression screening and major depression while controlling for confounders. RESULTS Arab American women were 23% less likely to be screened for depression compared to non-Hispanic white women (OR = 0.77; 95% CI = 0.70, 0.86). The age- and sex-adjusted proportions of major depression were 5.5% for Arab Americans compared to 7.0% for Hispanics, 6.0% for non-Hispanic blacks, 5.9% for non-Hispanic whites, and 1.5% for Asians. Arab Americans with major depression were less likely to follow up with a behavioral specialist and more likely to follow up with a primary care physician compared to other racial and ethnic groups. CONCLUSIONS Our study adds to the discourse on depression care among Arab Americans by highlighting the existing disparities related to adequate screening and appropriate management of depression. Future studies should include information about the influences of acculturation, culture, stigma, family, and religion on depression care.

Abstract
The objectives of this study were to estimate and compare the prevalence of heart disease, cancer, chronic lower respiratory disease, stroke, Alzheimer's, diabetes, nephrosis, flu/pneumonia, hypertension, and atherosclerosis between Arab Americans and whites attending a large, metropolitan hospital system. The sample included 68,047 patients, 18 years of age or older, who visited the hospital during 2012. Demographic and disease variables were electronically abstracted. Demographic characteristics were compared between Arab Americans and whites using Chi square tests. Sex specific, age-adjusted prevalence ratios (PR) and 95 % confidence intervals were estimated for these two groups using a log-binomial regression model. Compared to white men, Arab American men had a higher prevalence of diabetes (PR 1.40, 95 % CI 1.29-1.52) and hypertension (PR 1.07, 95 % CI 1.04-1.10), and a lower prevalence of chronic lower respiratory disease (PR 0.74, 95 % CI 0.66-0.83). Compared to white women, Arab American women had a higher prevalence of chronic lower respiratory disease (PR 1.12, 95 % CI 1.01-1.25), diabetes (PR 1.49, 95 % CI 1.38-1.60), influenza/pneumonia (PR 1.26, 95 % CI 1.05-1.51) and hypertension (PR 1.04, 95 % CI 1.01-1.08). This study supports previous findings that health disparities exist for Arab Americans, who are classified as "white" in health statistics. Standard inclusion of Arab American as a separate ethnicity category will aid researchers in assessing the health care needs of this growing minority community.

Abstract
OBJECTIVES We calculated cancer incidence for Arab Americans in California; Detroit, Michigan; and New Jersey, and compared rates with non-Hispanic, non-Arab Whites (NHNAWs); Blacks; and Hispanics. METHODS We conducted a study using population-based data. We linked new cancers diagnosed in 2000 from the Surveillance, Epidemiology, and End Results Program (SEER) to an Arab surname database. We used standard SEER definitions and methodology for calculating rates. Population estimates were extracted from the 2000 US Census. We calculated incidence and rate ratios. RESULTS Arab American men and women had similar incidence rates across the 3 geographic regions, and the rates were comparable to NHNAWs. However, the thyroid cancer rate was elevated among Arab American women compared with NHNAWs, Hispanics, and Blacks. For all sites combined, for prostate and lung cancer, Arab American men had a lower incidence than Blacks and higher incidence than Hispanics in all 3 geographic regions. Arab American male bladder cancer incidence was higher than that in Hispanics and Blacks in these regions. CONCLUSIONS Our results suggested that further research would benefit from the federal recognition of Arab Americans as a specified ethnicity to estimate and address the cancer burden in this growing segment of the population.

Abstract
PURPOSE Migrant studies often provide clues for cancer etiology. We estimated the cancer burden among Arab Americans (ArA) by immigrant status in the metropolitan Detroit area, home to one of the highest concentrations of ArA in USA. METHODS A validated name algorithm was used to identify ArA cancer cases diagnosed 1990-2009 in the Detroit SEER database. Recorded birthplace was supplemented with imputation of nativity using birthdate and social security number. Age-adjusted, gender-specific proportional incidence ratios and 95 % confidence intervals were calculated comparing all ArA, foreign-born ArA, and US-born ArA, to non-Hispanic Whites (NHW). RESULTS Foreign-born ArA males had higher proportions of multiple myeloma, leukemia, kidney, liver, stomach, and bladder cancer than NHW, while bladder cancer and leukemia were higher among US-born ArA males. For ArA women, gall bladder and thyroid cancers were proportionally higher among both foreign- and US-born compared with NHW. Stomach cancer was proportionally higher only among foreign-born women. CONCLUSIONS Cancer proportional incidence patterns among ArA show some similarity to other migrant groups, with higher proportional incidences of stomach and liver cancers among foreign-born than US-born. Other patterns, such as tobacco-related cancers among ArA men and gall bladder and thyroid cancers among ArA women, will require more investigation of genetic, epigenetic, and environmental factors.

Abstract
The objectives of this study were to: (1) calculate age-specific and age-adjusted cause-specific mortality rates for Arab Americans; and (2) compare these rates with those for blacks and whites. Mortality rates were estimated using Michigan death certificate data, an Arab surname and first name list, and 2000 U.S. Census data. Age-specific rates, age-adjusted all-cause and cause-specific rates were calculated. Arab Americans (75+) had higher mortality rates than whites and blacks. Among men, all-cause and cause-specific mortality rates for Arab Americans were in the range of whites and blacks. However, Arab American men had lower mortality rates from cancer and chronic lower respiratory disease compared to both whites and blacks. Among women, Arab Americans had lower mortality rates from heart disease, cancer, stroke, and diabetes than whites and blacks. Arab Americans are growing in number. Future study should focus on designing rigorous separate analyses for this population.

Abstract
Arab American (ArA) women may be at greater risk for thyroid cancer (TC) than White women. This case-case comparison explored differences in known and proposed risk factors of TC among ArA and non-Hispanic White (NHW) female TC cases in metropolitan Detroit. Cases of invasive TC identified from a population-based registry responded to a telephone survey regarding potential TC risk factors. Thirty ArA women (response rate 52%) and 70 NHW women (67%) participated. NHW women reported significantly more prior thyroid disease (TD), family history of TD, hormone use, cumulative years of hormone use, cigarette and alcohol consumption. In adjusted logistic regression analysis, ArA women had significantly higher odds of exposure to dental x-rays (OR = 3.48, CI 1.01-12.00) and medical radiation (OR = 13.58, CI 1.49-124.04) than NHW women. Risk factors for TC may differ among ArA women and their NHW counterparts.

Abstract
BACKGROUND Increases in thyroid papillary carcinoma incidence rates have largely been attributed to heightened medical surveillance and improved diagnostics. We examined papillary carcinoma incidence in an equal-access health care system by demographics that are related to incidence. METHODS Incidence rates during 1990-2004 among white and black individuals aged 20 to 49 years in the military, and the general U.S. population were compared using data from the Department of Defense's Automated Central Tumor Registry and the National Cancer Institute's Surveillance Epidemiology and End Results (SEER-9) program. RESULTS Incidence was significantly higher in the military than in the general population among white women [incidence rate ratio (IRR) = 1.42; 95% confidence interval (CI), 1.25-1.61], black women (IRR = 2.31; 95% CI, 1.70-2.99), and black men (IRR = 1.69, 95% CI, 1.10-2.50). Among whites, differences between the two populations were confined to rates of localized tumors (women: IRR = 1.73, 95% CI, 1.47-2.00; men: IRR = 1.51, 95% CI, 1.30-1.75), which may partially be due to variation in staging classification. Among white women, rates were significantly higher in the military regardless of tumor size and rates rose significantly over time both for tumors ≤ 2 cm (military: IRR = 1.64, 95% CI, 1.18-2.28; general population: IRR = 1.55, 95% CI, 1.45-1.66) and > 2 cm (military: IRR = 1.74, 95% CI, 1.07-2.81; general population: IRR = 1.48, 95% CI, 1.27-1.72). Among white men, rates increased significantly only in the general population. Incidence also varied by military service branch. CONCLUSIONS Heightened medical surveillance does not appear to fully explain the differences between the two populations or the temporal increases in either population. IMPACT These findings suggest the importance of future research into thyroid cancer etiology.

Abstract
AbstractObjective:This study aimed to determine the age at which various ethnic groups present with thyroid cancer.Method:Retrospective, observational study based at three district general hospitals in the West Midlands, serving a widely diverse ethnic population. We assessed all patients undergoing an operative or core biopsy procedure for a thyroid nodule from 1 January 1998 to 31 December 2009. Only patients diagnosed with thyroid cancer were included. Variables examined included the patient's ethnic origin, sex and age at presentation.Result:We identified 263 patients diagnosed with thyroid cancer. Papillary carcinoma predominated. Ethnicity was categorised as Caucasian, Asian, black or other. Thyroid cancer was predominantly seen in women, in all ethnic groups. The mean age of thyroid cancer presentation was 50 years in Asians and 56 years in Caucasians, for both sexes combined. The mean presentation age of Asian women was significantly younger (46 years) than that of Caucasian women (56 years) (p = 0.01).Conclusion:In this population, Asian women presented with thyroid cancer at a significantly younger mean age than Caucasian women.

Abstract
Previous studies have indicated that ionizing radiation, particularly during childhood, is the main established risk factor for thyroid cancer. History of benign nodules/adenoma, goiter, iodine deficiency or high-iodine intake might be other associated factors. We wanted to define the histology-specific thyroid cancer risk in the first-generation immigrants to Sweden. We used the 2010 update of the nation-wide Swedish Family-Cancer Database (>12 million individuals; 1.8 million immigrants; histology code in force since 1958) to calculate standardized incidence ratios (SIRs) for histology-specific thyroid cancer among immigrants compared to the native Swedes. The patient series covered 2,604 male and 6,406 female Swedes, and 247 and 863 immigrants. The median age at immigration was 29 years, and the median age at thyroid cancer diagnosis was 46 years. Increased risks for female papillary carcinoma were observed for Finns (SIR = 1.63), former Yugoslavians (2.36), Russians (2.34), other East Europeans (2.14), Turks (3.16), Iranians (2.68), Iraqis (2.77), East and Southeast Asians (2.92), other Asians (1.69) and South Americans (2.23). Male Iranians (2.85), East and Southeast Asians (3.57) and other Asians (2.26) had an increased risk for papillary carcinoma. Only male East and Southeast Asians (2.93) had an increased risk for follicular carcinoma. The data might suggest that immigrant populations in Sweden from areas of low or high-iodine intake are at risk of papillary carcinoma, implicating iodine imbalance as a contributing factor to our findings. The increased risk of thyroid cancer among Asian immigrants may confirm the role of childhood-ionizing radiation on thyroid cancer risk.

Abstract
Thyroid cancer incidence has been rising in the United States, and this trend has often been attributed to heightened medical surveillance and the use of improved diagnostics. Thyroid cancer incidence varies by sex and race/ethnicity, and these factors also influence access to and utilization of healthcare. We therefore examined thyroid cancer incidence rates by demographic and tumor characteristics based on 48,403 thyroid cancer patients diagnosed during 1980-2005 from the Surveillance, Epidemiology and End Results program of the National Cancer Institute. The rates varied by histologic type, sex, and race/ethnicity. Papillary carcinoma was the only histologic type for which incidence rates increased consistently among all racial/ethnic groups. Subsequent analyses focused on the 39,706 papillary thyroid cancers diagnosed during this period. Papillary carcinoma rates increased most rapidly among females. Between 1992-1995 and 2003-2005, they increased nearly 100% among White non-Hispanics and Black females but only 20% to 50% among White Hispanics, Asian/Pacific Islanders, and Black males. The increases were most rapid for localized stage and small tumors; however, rates also increased for large tumors and tumors of regional and distant stage. Since 1992-1995, half the overall increase in papillary carcinoma rates was due to increasing rates of very small (<or=1.0 cm) cancers, 30% to cancers 1.1 to 2 cm, and 20% to cancers>2 cm. Among White females, the rate of increase for cancers>5 cm almost equaled that for the smallest cancers. Medical surveillance and more sensitive diagnostic procedures cannot completely explain the observed increases in papillary thyroid cancer rates. Thus, other possible explanations should be explored.

Abstract
BACKGROUND The fast growing Middle Eastern (ME) population has rarely been studied in the U.S.. The purpose of this study was to compare the epidemiology of primary brain tumors in this ethnic population with the non-Hispanic, non-Middle Eastern White (NHNMW) in California. METHODS ME cases were identified by surname in the California cancer registry and ME population estimates were based on ancestry. Data for 683 cases of primary brain tumors (429 benign, 238 malignant, 16 uncertain) in the ME and 15,589 cases (8352 benign, 6812 malignant, 425 uncertain) in the NHNMW were available for this study. RESULTS ME patients were significantly (p < 0.05) younger and their age-adjusted incidence rates per 100,000 for benign tumors of 10.0 in men and 17.6 in women were higher than similar rates of 7.3 and 10.6 in the NHNMW group (p < 0.05). Rates for malignant tumors were similar. Meningioma was the main histology responsible for the observed increase in patients over 40 years of age. Also increased were benign tumors of the pituitary and pineal glands. The overall mortality in patients with benign tumors was significantly lower than malignant tumors. CONCLUSIONS This study presents a significantly high incidence of benign meningioma in the ME population in California. This may be due to higher susceptibility or exposure of this ethnic group to the risk factor(s) for this neoplasm. Considering the reported causal association of benign meningioma with childhood radiation exposure from Israel, exposure to this risk factor in this ethnic group needs to be evaluated in future studies.
