  • biliary tract cancer incidence in the united states demographic and temporal variations by anatomic site
    International Journal of Cancer, 2013
    Co-Authors: Felipe A Castro, Jill Koshiol, Ann W Hsing, Susan S Devesa
    Abstract:

    We evaluated incidence patterns of biliary tract cancers (gallbladder, extrahepatic bile duct, ampulla of Vater, and not otherwise specified) to provide potential insight into the etiology of these cancers. Data were obtained from the population-based Surveillance, Epidemiology, and End Results (SEER) program. Rates for cases diagnosed during 1992–2009 were calculated by racial/ethnic, gender, and age groups. Temporal trends during 1974–2009 and annual percentage changes (APC) during 1992–2009 were estimated. Age-adjusted rates by site were higher among American Indian/Alaska Natives, Hispanics (white) and Asian/Pacific Islanders (Asian/PI) and lower among whites and blacks. Gallbladder cancer was more common among women in all ethnic groups (female-to-male incidence rate ratio [IRR] ranged from 1.24 to 2.86), but bile duct and ampulla of Vater cancers were more common among men (female-to-male IRR 0.57 to 0.82). Gallbladder cancer rates declined among all racial/ethnic and gender groups except blacks (APC −0.4% to −3.9%). In contrast, extrahepatic bile duct cancer rates rose significantly in most female racial/ethnic groups; the APCs among whites were 0.8 among females and 1.3 among males, both significant. Rates for ampulla of Vater cancer decreased among Asian/PI females (APC −2.7%) but remained stable for the other groups. In addition to confirming that biliary tract cancer incidence patterns differ by gender and site, and that the gallbladder cancer incidence rates have been declining, this study provides novel evidence that extrahepatic bile duct cancer rates are rising. These observations may help guide future etiologic studies.

  • cutaneous lymphoma incidence patterns in the united states a population based study of 3884 cases
    Blood, 2009
    Co-Authors: Porcia T Bradford, Susan S Devesa, William F Anderson, Jorge R Toro
    Abstract:

    There have been no prior large population-based studies focusing on cutaneous lymphomas (CL) in the United States. Using the Surveillance, Epidemiology and End Results (SEER) program data, we analyzed age-adjusted CL incidence rates (IRs) and survival rates by sex and race/ethnicity. There were 3884 CLs diagnosed during 2001-2005. Cutaneous T-cell lymphomas (CTCLs) accounted for 71% (age-adjusted incidence rate [IR] = 7.7/1 000 000 person-years), whereas cutaneous B-cell lymphomas(CBCLs) accounted for 29% (IR = 3.1/1 000 000 person-years). Males had a statistically significant higher IR of CL than females (14.0 vs 8.2/1 000 000 person-years, respectively; male-female IR ratio [M/F IRR] = 1.72; P < .001). CL IRs were highest among blacks and non-Hispanic whites (both 11.5/1 000 000 person-years), followed by Hispanic whites (7.9) and Asian/Pacific Islanders (7.1). The CTCL IR was highest among blacks (10.0/1 000 000 person-years), whereas the CBCL IR was highest among non-Hispanic whites (3.5). Over the past 25 years, the CL IR increased from 5.0/1 000 000 person-years during 1980-1982 to 14.3 during 2001-2003. During 2004-2005, the CL IR was 12.7. This recent apparent change could be incomplete case ascertainment or potential leveling off of IRs. CLs rates vary markedly by race and sex, supporting the notion that they represent distinct disease entities.

  • rising thyroid cancer incidence in the united states by demographic and tumor characteristics 1980 2005
    Cancer Epidemiology Biomarkers & Prevention, 2009
    Co-Authors: Lindsey Enewold, Kangmin Zhu, Elaine Ron, Aizen J Marrogi, Alexander Stojadinovic, George E Peoples, Susan S Devesa
    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 ( 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.

  • cutaneous soft tissue sarcoma incidence patterns in the u s an analysis of 12 114 cases
    Cancer, 2008
    Co-Authors: Panta Rouhani, Susan S Devesa, Christopher D M Fletcher, Jorge R Toro
    Abstract:

    BACKGROUND. Cutaneous soft tissue sarcomas (CSTS) are a heterogeneous group of mesenchymal neoplasms. To the authors' knowledge, no prior large, population-based study has focused on CSTS. METHODS. Surveillance, Epidemiology, and End Results (SEER) Program incidence and relative survival rates of CSTS were analyzed according to race, sex, and histologic type using the 2002 criteria of the World Health Organization classification. RESULTS. Among residents of the 13 SEER registries, 12,114 CSTS were diagnosed from 1992 through 2004. Overall age-adjusted CSTS incidence rates were highest among blacks (30.8 per 1,000,000 person-years) followed by whites (25 per 1,000,000 person-years), and American Indians/Alaska Natives (11.2 per 1,000,000 person-years) and were lowest among Asian/Pacific Islanders (7.7 per 1,000,000 person-years). Kaposi sarcoma (KS) accounted for 71.1% of cases, and the rates were similarly ranked. Dermatofibrosarcoma protuberans (DFSP) rates also were highest among blacks, whereas leiomyosarcoma (LS) and angiosarcoma (AS) rates were highest among whites. The rate ratio of men to women was 25.5 for KS, 4.7 for malignant fibrous histiocytoma (MFH), 3.7 for LS, 2.0 for AS, and 0.9 for DFSP. The 5-year relative survival rates were 99% for patients with DFSP, 89% for patients with MFH, 92% for patients with LS, and 45% for patients with AS. KS rates among men in the original 9 SEER registries increased more than 30-fold during the 1980s before they peaked around 1991 and subsequently declined rapidly because of human immunodeficiency virus-associated KS and highly active antiretroviral therapy. This KS pattern was evident not only among those ages 20 to 59 years but also among those ages 60 to 69 years. From 1978 through 2004, LS and AS rates among whites increased exponentially. CONCLUSIONS. CSTS rates varied markedly over time and by race, sex, and histologic type, supporting the notion that these histologic variants of CSTS areetiologically distinct.

  • relationships of sex hormone levels with leukocyte telomere length in black hispanic and Asian Pacific islander postmenopausal women
    Journal of Diabetes, 2018
    Co-Authors: Yiqing Song, Yan Song, Kathleen Brennan, Brian H Chen, Joann E Manson, Andrea L Hevener, Anthony W Butch
    Abstract:

    Background Sex hormones may play important roles in sex-specific biological aging. We specifically examined the associations between circulating concentrations of sex hormones and leukocyte telomere length (TL). Methods We conducted a cross-sectional study of 1124 black, 444 Hispanic, and 289 Asian/Pacific Islander women in the Women's Health Initiative Observational Cohort. Concentrations of estradiol and testosterone were measured using electrochemiluminescence immunoassays. TL was measured using quantitative PCR. Results Women included in the study were 50 to 79 years of age. Levels of estradiol were not significantly associated with TL in this sample of women. The associations between total and free testosterone and TL differed by race/ethnicity (P for interaction = 0.03 for total testosterone and 0.05 for free testosterone). Total and free testosterone concentrations were not associated with TL in black and Hispanic women, whereas in Asian/Pacific Islanders, their concentrations were inversely associated with TL (P-trend = 0.003 for both). These associations appeared robust in multiple subgroup analysis and multivariable models adjusted for potential confounding factors. In Asian/Pacific Islanders, doubling of serum free testosterone concentration was associated with 202 bp shorter TL (95% CI, 51 to 353 bp), and doubling of total testosterone concentration was associated with 203 bp shorter TL (95% CI, 50 to 355 bp). Conclusions Serum concentration of estradiol was not associated with leukocyte TL in this large sample of postmenopausal women. Total and free testosterone levels were inversely associated with TL in Asian/Pacific Islander women but not in black and Hispanic women, although future studies to replicate our observations are warranted particularly to address potential ethnicity-specific relations. The significant findings of the study This study elucidates the potential roles of sex hormones in biological aging, and identified that total and free testosterone levels were inversely associated with telomere length in Asian/Pacific Islander women but not in black and Hispanic women. The study adds The findings of this study suggest that Asian/Pacific Islander women may be susceptible to the potential detrimental effects of high testosterone level on biologic aging.

  • common genetic variation in calpain 10 gene capn10 and diabetes risk in a multi ethnic cohort of american postmenopausal women
    Human Molecular Genetics, 2007
    Co-Authors: Yiqing Song, Lesley F Tinker, Charles B. Eaton
    Abstract:

    Calpain-10 (CAPN10) protein may play a role in glucose metabolisms, pancreatic β-cell insulin secretion and thermogenesis. Emerging evidence has implicated a role of CAPN10 genetic variants in the risk of type 2 diabetes mellitus (T2DM). Previous association studies, however, have focussed only on several variants initially reported and provided inconsistent results. We conducted a large nested case-control study to comprehensively investigate the associations between common variations in CAPN10 gene and T2DM risk among postmenopausal women aged 50-79 years from the Women's Health Initiative Observational Study. After comprehensive screening in 244 randomly chosen control samples (n = 61 for each of four ethnic groups), we selected a total of 12 tagging single nucleotide polymorphisms (tSNPs) spanning 91 kb in CAPN10 and genotyped them in 1543 diabetes cases and 2132 matched controls (including 968 cases and 968 controls for whites, 366 and 732 for blacks, 152 and 303 for Hispanics and 98 and 195 for Asian/Pacific Islanders). There were no significant associations between any individual tSNP and T2DM, within either the full study sample or any specific ethnic group. Nor was there any evidence of association between common CAPN10 haplotypes and diabetes risk (global tests for differences in risk were P = 0.31 for overall common haplotypes, P = 0.44 for haplotypes in block 1 and P = 0.37 for haplotypes in block 2). In conclusion, we did not observe any significant associations of the common SNPs or haplotypes across the CAPN10 gene with diabetes risk in our large and ethnically diverse cohort of postmenopausal women.

  • biliary tract cancer incidence in the united states demographic and temporal variations by anatomic site
    International Journal of Cancer, 2013
    Co-Authors: Felipe A Castro, Jill Koshiol, Ann W Hsing, Susan S Devesa
    Abstract:

    We evaluated incidence patterns of biliary tract cancers (gallbladder, extrahepatic bile duct, ampulla of Vater, and not otherwise specified) to provide potential insight into the etiology of these cancers. Data were obtained from the population-based Surveillance, Epidemiology, and End Results (SEER) program. Rates for cases diagnosed during 1992–2009 were calculated by racial/ethnic, gender, and age groups. Temporal trends during 1974–2009 and annual percentage changes (APC) during 1992–2009 were estimated. Age-adjusted rates by site were higher among American Indian/Alaska Natives, Hispanics (white) and Asian/Pacific Islanders (Asian/PI) and lower among whites and blacks. Gallbladder cancer was more common among women in all ethnic groups (female-to-male incidence rate ratio [IRR] ranged from 1.24 to 2.86), but bile duct and ampulla of Vater cancers were more common among men (female-to-male IRR 0.57 to 0.82). Gallbladder cancer rates declined among all racial/ethnic and gender groups except blacks (APC −0.4% to −3.9%). In contrast, extrahepatic bile duct cancer rates rose significantly in most female racial/ethnic groups; the APCs among whites were 0.8 among females and 1.3 among males, both significant. Rates for ampulla of Vater cancer decreased among Asian/PI females (APC −2.7%) but remained stable for the other groups. In addition to confirming that biliary tract cancer incidence patterns differ by gender and site, and that the gallbladder cancer incidence rates have been declining, this study provides novel evidence that extrahepatic bile duct cancer rates are rising. These observations may help guide future etiologic studies.
