Breast Cancer Fatalism: The Role Of Women's Perceptions Of The Health Care System, Allyson G. Hall, Amal J. Khoury, Ellen D.S. Lopez, Nedra Lisovicz, Amanda Avis-Williams, Amal K. Mitra

Faculty Publications

Cancer fatalism, which can be understood as the belief that cancer is a death sentence, has been found to be a deterrent to preventive cancer screening participation. This study examines factors associated with breast cancer fatalism among women. We analyzed data from a 2003 survey of women 40 years of age. The survey collected information about respondents' knowledge and attitudes regarding breast health. Analyses compared the characteristics of women who reported and those who did not report a fatalistic attitude. Women with a fatalistic attitude were more likely to be African American, to have a family history of breast cancer, …

Explaining The Race Difference In Prostate Cancer Stage At Diagnosis, Beth A. Jones, Wen-Liang Liu, Andre B. Araujo, Stanislav V. Kasl, Stephanie A. Navarro Silvera, Hosanna Soler-Vila, Mary G.M. Curnen, Robert Dubrow

Department of Public Health Scholarship and Creative Works

Prostate cancer is the most frequently diagnosed cancer in males in the United States, accounting for an estimated 186,320 new cases in 2008. There are striking racial or ethnic differences in prostate cancer incidence and mortality rates in the United States, with Black males 1.6 times more likely to be diagnosed and 2.4 times more likely to die with prostate cancer than Whites. The stage at diagnosis is a key prognostic factor for prostate cancer survival, with African-Americans generally diagnosed at a more advanced stage. To identify factors that explain the race-stage disparity in prostate cancer, we conducted a population-based …

Cancer In American Indian And Alaska Native Young Adults (Ages 20–44 Years): Us, 1999–2004, Hannah K. Weir, Melissa Jim, Loraine D. Marrett, Temeika L. Fairley

Public Health Resources

BACKGROUND. An examination of cancer incidence patterns in American Indians and Alaska Native (AI/AN) young adults may provide insight into their present and future cancer burden.

METHODS. To reduce racial misclassification, incidence data were linked with the Indian Health Service (IHS) patient services database. Age-adjusted cancer incidence rates per 100,000 (AAR) and corresponding rate ratios (RR) for young adults (ages 20-44 years) were compared across IHS regions and for selected cancers within Contract Health Service Delivery Area counties by race (AI/AN vs non-Hispanic whites [NHW]) and sex.

RESULTS. The all-sites cancer incidence rate was lower for AI/ANs …

Incidence Of Cancers Of The Oral Cavity And Pharynx Among American Indians And Alaska Natives, 1999–2004, Marsha E. Reichman, Janet J. Kelly, Carol L. Kosary, Steven S. Coughlin, Melissa Jim, Anne P. Lanier

Public Health Resources

BACKGROUND. Previous studies identified disparities in incidence rates of cancers of the oral cavity and pharynx between American Indians/Alaska Natives (AI/AN) and non-Hispanic whites (NHW) and differences between various AI/AN populations. Reporting among AI/AN has been hampered by: 1) heterogeneity among various anatomic sites of oral cavity and pharyngeal cancers obscuring unique patterns of individual anatomic sites; 2) race misclassification and under-reporting of AI/AN; and 3) sparseness of data needed to identify regional variations.

METHODS. To improve race classification of AI/AN, data from US central cancer registries were linked with Indian Health Service (IHS) records. AI/AN incidence data …

Gastric Cancer Among American Indians And Alaska Natives In The United States, 1999–2004, Charles Wiggins, David G. Perdue, Jeffrey A. Henderson, Michael G. Bruce, Anne P. Lanier, Janet J. Kelly, Brenda F. Seals, David K. Espey

Public Health Resources

BACKGROUND. Gastric cancer incidence rates for American Indians and Alaska Natives (AI/ANs) historically have exceeded those for non-Hispanic whites (NHWs). Previous reports may have underestimated the true burden of gastric cancer in AI/AN populations because of misclassification of AI/AN race in cancer registries.

METHODS. Population-based cancer registry data from 1999 through 2004 were used to describe gastric cancer incidence in AI/ANs and NHWs in the US. To address misclassification of race, registry data were linked with Indian Health Service administrative records, and analyses were restricted to residents of Contract Health Service Delivery Areas (CHSDA). Disease patterns were assessed …

Acute Exercise Protects Against Doxorubucin Cardiotoxicity, Karen Y. Wonders, David S. Hydock, Carole M. Schneider, Reid Hayward

School of Sport & Exercise Science Faculty Publications

Numerous methods have been used to minimize the cardiotoxic effects of the chemotherapeutic agent doxorubicin (DOX), and most have had limited success. Chronic endurance exercise has been shown to protect against DOX cardiotoxicity, but little is known regarding the effects of acute exercise on DOX-induced cardiac dysfunction. Purpose. The purpose of this study was to determine the effects of a single bout of acute endurance exercise on the cardiac dysfunction associated with DOX treatment. Methods. Male Sprague-Dawley rats either performed an acute exercise bout on a motorized treadmill for 60 minutes at a maximal speed of 25 m/min with a …

Treg Depletion Inhibits Efficacy Of Cancer Immunotherapy: Implications For Clinical Trials., James Curtin, Marianela Candolfi, Tamer Fakhouri, Chunyan Liu, Anderson Alden, Matthew Edwards, Pedro Lowenstein, Maria Castro

Articles

BACKGROUND: Regulatory T lymphocytes (Treg) infiltrate human glioblastoma (GBM); are involved in tumor progression and correlate with tumor grade. Transient elimination of Tregs using CD25 depleting antibodies (PC61) has been found to mediate GBM regression in preclinical models of brain tumors. Clinical trials that combine Treg depletion with tumor vaccination are underway to determine whether transient Treg depletion can enhance anti-tumor immune responses and improve long term survival in cancer patients. FINDINGS: Using a syngeneic intracrabial glioblastoma (GBM) mouse model we show that systemic depletion of Tregs 15 days after tumor implantation using PC61 resulted in a decrease in Tregs …

Management Of Oral Mucositis In Patients With Cancer, Rajesh V. Lalla, Douglas E. Peterson

UCHC Articles - Research

Oral mucositis refers to erythematous and ulcerative lesions of the oral mucosa observed in patients with cancer being treated with chemotherapy, and/or with radiation therapy to fields involving the oral cavity. Lesions of oral mucositis are often very painful and compromise nutrition and oral hygiene as well as increase risk for local and systemic infection. Mucositis can also involve other areas of the alimentary tract; for example, gastrointestinal (GI) mucositis can manifest as diarrhea. Thus, mucositis is a highly significant and sometimes dose-limiting complication of cancer therapy.

Impaired Clearance Of Methotrexate In Organic Anion Transporter 3 (Slc22a8) Knockout Mice: A Gender Specific Impact Of Reduced Folates, Adam L. Vanwert, Douglas H. Sweet

Pharmaceutics Publications

Purpose

To elucidate the role of the renal basolateral transporter, Oat3, in the disposition of methotrexate.

Materials and Methods

Chinese hamster ovary cells expressing mouse Oat3 were used to determine kinetics and specificity of inhibition of methotrexate transport. Methotrexate clearance was then examined in vivo in wildtype and Oat3 knockout mice.

Results

NSAIDs, ß-lactams, and uremic toxins inhibited mOat3-mediated methotrexate uptake by 70–100%, while folate, leucovorin, and 5-methyltetrahydrofolate inhibited transport by 25–50%. A Km of 60.6±9.3 μM for methotrexate transport was determined. Oat3 knockout mice exhibited reduced methotrexate-to-inulin clearance ratios versus wildtype. Male wildtype mice, but not knockouts or …

Polysaccharopeptide Enhances The Anticancer Activity Of Doxorubicin And Etoposide On Human Breast Cancer Cells Zr-75-30, Jennifer Man-Fan Wan, Wai Hung Sit, Jimmy Chun Yu Louie

Faculty of Health and Behavioural Sciences - Papers (Archive)

In search of natural bioactive microbial compounds with adjuvant properties, we have previously showed that the polysaccharopeptide (PSP), isolated from Chinese medicinal mushroom Coriolus versicolor, was able to enhance the cytotoxicity of certain S-phase targeted-drugs on human leukemic HL-60 cells via some cell-cycle and apoptotic-dependent pathways. The present study aimed to investigate whether the synergism of mechanisms of PSP with certain chemotherapeutic drugs also applies to human breast cancer. PSP treatment enhanced the cytotoxicity of doxorubicin (Doxo), etoposide (VP-16) but not cytarabine (Ara-C). Bivariate bromodeoxyuridine (BrdUrd)/DNA flow cytometry analysis estimated a longer DNA synthesis time (Ts) for the PSP treated …

Lung Cancer Incidence Among American Indians And Alaska Natives In The United States, 1999–2004, Anne Bliss, Nathaniel Cobb, Teshia Solomon, Kym Cravatt, Melissa A. Jim, Latisha Marshall, Janis Campbell

Public Health Resources

BACKGROUND. Lung cancer incidence rates among American Indians and Alaska Natives (AI/ANs) in the United States have not been described well, primarily because of race misclassification and, until the 1990s, incomplete coverage of their population by cancer registries. Smoking, the predominant cause of lung cancer, is particularly prevalent among this population.

METHODS. Data from the National Program of Cancer Registries and the Surveillance, Epidemiology, and End Results Program were combined to estimate age adjusted incidence rates of lung cancer during 1999 through 2004. Cases were linked to Indian Health Service (IHS) registration databases to identify AI/ANs whose race …

Methods For Improving Cancer Surveillance Data In American Indian And Alaska Native Populations, David K. Espey, Charles Wiggins, Melissa A. Jim, Barry A. Miller, Christopher J. Johnson, Tom M. Becker

Public Health Resources

BACKGROUND. The misclassification of race decreases the accuracy of cancer incidence data for American Indians and Alaska Natives (AI/ANs) in some central cancer registries. This article describes the data sources and methods that were used to address this misclassification and to produce the cancer statistics used by most of the articles in this supplement.

METHODS. Records from United States cancer registries were linked with Indian Health Service (IHS) records to identify AI/AN cases that were misclassified as non-AI/AN. Data were available from 47 registries that linked their data with IHS, met quality criteria, and agreed to participate. Analyses …

Prostate Cancer Incidence Among American Indian And Alaska Native Men, Us, 1999–2004, Jeffrey A. Henderson, David K. Espey, Melissa Jim, Robert R. German, Kate M. Shaw, Richard M. Hoffman

Public Health Resources

BACKGROUND. American Indian and Alaska Native (AI/AN) men experience lower incidence of prostate cancer than other race/ethnic populations in the US, but racial misclassification of AI/AN men threatens the validity of these estimates. To the authors’ knowledge, little is known concerning prostate-specific antigen (PSA) testing in AI/AN men.

METHODS. The authors linked cancer registry data with Indian Health Service enrollment records to improve race classification. Analyses comparing cancer incidence rates and stage at diagnosis for AI/AN and non-Hispanic white (NHW) men for 6 geographic regions focused on counties known to have less race misclassification. The authors also used …

Using Population-Based Cancer Registry Data To Assess The Burden Of Human Papillomavirus-Associated Cancers In The United States: Overview Of Methods, Meg Watson, Mona Saraiya, Faruque Ahmed, Cheryll J. Cardinez, Marsha E. Reichman, Hannah K. Weir, Thomas B. Richards

Public Health Resources

Increased attention to human papillomavirus (HPV)-associated cancers in light of the recent release of an HPV vaccine, as well as increased availability of cancer registry data that now include reporting from a large proportion of the US population, prompted the current assessment of HPV-associated cancers. This article describes methods used to assess the burden of HPV-associated cervical, vulvar, vaginal, penile, anal, and oral cavity/oropharyngeal cancers in the United States during 1998 through 2003 using cancer registry data, and it provides a brief overview of the epidemiology of these cancers.

Persistent infection with the human papillomavirus (HPV) is considered to be …

Cancer Among American Indians And Alaska Natives In The United States, 1999–2004, Charles Wiggins, David K. Espey, Phyllis A. Wingo, Judith S. Kaur, Robin Taylor Wilson, Judith Swan, Barry A. Miller, Melissa Jim, Janet J. Kelly, Anne P. Lanier

Public Health Resources

BACKGROUND. Cancer incidence rates vary among American Indian and Alaska Native (AI/AN) populations and often differ from rates among non-Hispanic whites (NHWs). However, the misclassification of race for AI/AN cancer cases in central cancer registries may have led to underestimates of the AI/AN cancer burden in previous reports.

METHODS. Cases diagnosed during 1999 through 2004 were identified from population- based cancer registries in the United States. Age-adjusted rates were calculated for the 25 most common sites for AI/ANs and NHWs. To minimize the misclassification of race, cancer registry records were linked with patient registration files from the Indian …

Chlorothalonil Exposure And Cancer Incidence Among Pesticideapplicator Participants In The Agricultural Health Study, Alicia M. Mozzachio, Jennifer A. Rusiecki, Jane A. Hoppin, Rajeev Mahajan, Rahulkumar Patel, Laura Beane-Freeman, Michael Cr Alavanja

Uniformed Services University of the Health Sciences

Background: Chlorothalonil is a broad spectrum, non-systemic fungicide widely used to control diseases affecting over 50 fruit, vegetable, and agricultural crops. Despite its extensive use for over 30 years, little is known about the potential human carcinogenicity associated with the routine application of chlorothalonil. Rodent studies have shown evidence of renal tubular carcinomas and adenomas. We explored cancer incidence with chlorothalonil exposure using data from the Agricultural Health Study, a prospective cohort of licensed pesticide applicators in Iowa and North Carolina.
Methods: Licensed private and commercial pesticide applicators were recruited into this study from 1993 to 1997. Detailed information regarding …

The Efficacy Of Complementary Therapies In Reducing Cancer-Related Pain, Sarah A. Hocking

Student Works

Pain is a persistent and troubling condition for patients with cancer. Because medications often provide incomplete management of cancer-related pain, adjunct treatment may be necessary to provide more complete pain management. Complementary and alternative therapies are becoming increasingly prevalent in cancer pain management. However, lack of knowledge regarding the efficacy of complementary therapies may prevent patients and nurses from implementing them. The purpose of this article is to provide a review of literature on the efficacy of various complementary and alternative therapies for managing cancer-related pain, including massage, aromatherapy, hypnosis, and music therapy. Eighteen recent research articles related to this …

Living Past Your Expiration Date: A Phenomenological Study Of Living With Stage Iv Cancer Longer Than Expected, Cynthia Levine

Antioch University Full-Text Dissertations & Theses

More treatment options exist today for persons diagnosed with terminal cancerextending lives longer than expected though there is little known about the psychosocial needs or resources for these individuals. This study describes the experience of living past the expiration date and still living with Stage IV cancer. A transcendental phenomenological approach was used to elucidate vivid expressions of this experience in a sample population of five Caucasian women. The women survived beyond their prognoses of an earlier expiration are not close to imminent death and are still living with incurable breast cancer metastases. The aim of this phenomenological inquiry is …
