Primary and secondary prevention of colorectal cancer.

Colorectal cancer is the third leading cause of cancer deaths in the United States. Because of the nature and the progression of the disease, it is highly preventable and suitable for screening. Yet the American Cancer Society estimates included over 100,000 cases of new occurrence of colorectal cancer and over 50,000 deaths in the year 2002. The continued high colorectal cancer mortality rate is due to the under utilization of screening tests.This review will explore the barriers to low screening test use. Implications for healthcare professionals on how to increase the general populations' awareness of colorectal cancer and ways to increase adherence to screening by integrating theories of the Health Belief Model will be discussed. The current research and literature about primary prevention focused on modifiable risk factors and chemoprevention will be examined. Secondary prevention, however, will be the key to help reduce the mortality and morbidity of colorectal cancer. The current screening guidelines will be reviewed as well. It is possible to increase screening rate by modifying and influencing patients' perceived cancer risk, and by educating and training healthcare providers.     

Enhancing knowledge of colorectal cancer among African Americans: why are we waiting until age 50?

Because of low rates of colorectal cancer screening among African Americans, it may be beneficial to begin educating persons about this disease before age 50. Using the Patient/Provider/System Theoretical Model for cancer screening, this study compared knowledge of colorectal cancer, sources of information, and awareness of programs among participants of age 20-29, 30-49, and 50-75 years. The majority (n = 354) were women and African American (mean age = 37 years, mean education = 12th grade). Younger participants tended to know less about the disease, but there were few differences in knowledge between the two older groups. Persons in the 40-49-year age group were more likely to be familiar with the role diet plays in the risk of colorectal cancer. Participants associated the need for screening with the presence of symptoms. Television and radio were listed as the most frequent source of information about cancer. The Internet was the least used. The majority were not familiar with selected national programs and services focused on increasing awareness of cancer. Findings suggest that colorectal cancer-related information should be targeted toward this population before age 50, using multiple sources such as TV/radio, providers, magazines, and cancer-related organizations. An estimated 104,950 colon and 40,340 rectal cancer cases will be diagnosed in 2005 with an estimated 56,290 deaths from the disease (American Cancer Society [ACS], 2005). Despite a stabilization of colorectal cancer (CRC) incidence rates since the 1980s, African American males and females have higher incidence and mortality rates associated with this disease compared to Whites. The 5-year survival rate for CRC among African Americans improved to 54% during the years 1995-2000, but lagged well behind the 64% survival rate for Whites during the same time period. Screening and early detection of CRC followed by effective treatment is crucial to reducing these mortality rates.     

Colorectal cancer screening: an overview of available methods and current recommendations

BACKGROUND: Screening asymptomatic persons for colorectal cancer may decrease the incidence and mortality of this disease. METHODS: The MEDLINE database was used to identify articles addressing the rationale for colorectal cancer screening, methods used and their effectiveness, and current recommendations. RESULTS: Methods of screening for colorectal cancer include flexible sigmoidoscopy, fecal occult blood tests, barium enema, and colonoscopy. The method used and the frequency of screening are determined by assessing an individual's risk of having colorectal cancer. CONCLUSIONS: Colorectal cancer is a common malignancy in the United States, is curable when detected at an early stage, and is potentially preventable. The acceptance of colorectal cancer screening by patients and physicians has been suboptimal. while there remains little debate about the potential for screening to reduce mortality from colorectal cancer, debate continues about the cost-effectiveness of colorectal cancer screening when applied to the general population.     

The decreasing burden of gastric cancer in Japan

Gastric cancer in Japan, previously the top killer cancer, has recently shown decreased incidence and mortality rates. Epidemiological studies have demonstrated that environmental factors are closely associated with stomach oncogenesis, as evident from the geographical differences seen throughout Japan in both incidence and mortality. Moreover, Japanese immigrant populations gradually exhibit the lower incidence and mortality rates of gastric cancer in their chosen country. Likewise, younger generations in Japan have lower mortality rates than older generations at the same age, which may be accounted by the dramatic lifestyle changes in Japan after World War II. In addition to exploring and learning from the impact of these environmental factors, deliberate strategies to further lower the incidence and mortality rates of gastric cancer must include aggressive eradication programs for Helicobacter pylori and dietary education in both school curricula and for the general adult population to lower the intake of causative agents such as salt and increase the intake of beneficial agents such as fruits, vegetables and seaweeds. The dietary education should be coupled with better motivation for the general population to undergo regular screening with improved techniques. In the future, changes in these environmental factors and progresses in the diagnosis of and therapeutic strategies for gastric cancer will lead to further decrease in the incidence and mortality rates of this disease in Japan.     

Screening of patients at average risk for colon cancer

Both the incidence and the mortality from colorectal cancer can be substantially reduced by primary and secondary prevention. There are many screening tests for colorectal cancer, and any test should result in a reduction in colorectal cancer incidence and mortality. If the age-eligible population undergoes these screening tests, the burden of colorectal cancer should be substantially reduced. The scientific evidence related to secondary prevention, specifically screening of individuals at average risk for colorectal cancer, is presently reviewed.     

Influence of patient-provider communication on colorectal cancer screening

BACKGROUND: Screening reduces incidence and mortality from colorectal cancer (CRC). Despite improved access, screening is suboptimal and disparate among minority groups. Quality of patient-provider communication may impact CRC screening. OBJECTIVES: We examined the relationship between patient-provider communication and socioeconomic variables on the receipt of CRC screening using data from the Medical Expenditure Panel Survey. SUBJECTS: All persons age 50 years or older (N = 8488). MEASURES: Dependent measures were receipt of CRC screening, fecal occult blood testing, and colonoscopy or sigmoidoscopy. Independent variables included demographic characteristics, patient language, and patient-provider communication measures from the Consumer Assessment of Health Plan survey. RESULTS: Patients who felt they had sufficient time with their healthcare provider were more likely to be screened for CRC. Receiving adequate explanation of healthcare needs from provider was a significant predictor of fecal occult blood testing screening. In addition, persons with less than a high school education, the uninsured, or those with low income were associated with reduced likelihood of receiving CRC screening. Asians and Hispanics had a significantly reduced likelihood of receiving screening in comparison with whites; however, after adjusting for language, no significant differences for race or ethnicity were observed. CONCLUSIONS: Adequate time with a healthcare provider and receiving sufficient explanation of the healthcare processes by providers may improve screening rates. Patient-provider communication may be improved by addressing language needs of non-English speaking patients. Overall improved communication may increase CRC screening rates in underserved populations.     

Colorectal cancer knowledge, perceptions, and behaviors in African Americans

Disparities in healthcare among racial and ethnic minorities are associated with poor outcomes. African Americans have the highest incidence of colorectal cancer (CRC) among all racial groups. Using a nonrandom sample of 100 African American men and women, 50 years of age and older, the authors explored CRC knowledge, perceptions, and screening behaviors of African American men and women who resided or worked in an urban low-income housing residence. The extent to which screening may be attributed to demographic, sociopsychological, and structural variables was also investigated. Respondents demonstrated inadequate knowledge of CRC, with a significant difference in mean scores between males and females. Self-report of participation in CRC screening was above the national average, with almost half of the sample reporting fecal occult blood home kit use and more than half of the sample reporting completion of sigmoid and colonoscopy exams and double contrast barium enema exam. A majority perceived CRC as a threat. A very high percentage perceived numerous benefits to CRC screening in preventing CRC susceptibility. Perceived barriers of nearly half of the sample included screening may be painful and afraid to find out something is wrong if I have CRC screening, while more than half did not know how to schedule screening. Barriers and threat were correlated with grade school education. Barriers were negatively correlated with secondary education and post-secondary education and moderately correlated with threat. Predictor variables found in the Health Belief Model accounted for a significant amount of the variance in screening behavior, barriers, and threat. Older African American men and women need more information about CRC in order to increase their awareness of CRC and the importance of screening. There is a need to educate healthcare professionals about the causes, prevention, and detection of CRC and the importance of screening.     

Colon cancer screening in African American women.

African American women are more likely to die of colorectal cancer than are women of any other racial or ethic group. Early diagnosis depends on routine examination and screening. However, studies have shown that African American women are not utilizing available screening tools. African American women age fifty or older were questioned about their risk factors and frequency of CRC screening. The conceptual framework used was the Health Belief Model. Women who perceived fewer barriers, more benefits, higher perceived susceptibility, and increased confidence in the accuracy of screening, were likely to undergo screening. Implications for nursing practice are discussed especially focused on the role of advanced practice nurses as primary care providers. Utilization of a faith-based approach to reaching this population was also suggested.     

Challenges in providing breast and cervical cancer screening services to Vietnamese Canadian women: the healthcare providers' perspective

Breast cancer and cervical cancer are major contributors to morbidity and mortality among Vietnamese Canadian women. Vietnamese women are at risk because of their low participation rate in cancer-preventative screening programmes. Drawing from the results of a larger qualitative study, this paper reports factors that influence Vietnamese women's participation in breast and cervical cancer screening from the healthcare providers' perspectives. The women participants' perspective was reported elsewhere.
Semistructured interviews were conducted with six healthcare providers. Analysis of these interviews reveals several challenges which healthcare providers encountered in their clinical practice. These include the physicians' cultural awareness about the private body, patient's low socioeconomic status, the healthcare provider–patient relationship, and limited institutional support.
This is the first Canadian study to identify the healthcare providers' perspective on giving breast and cervical cancer preventive care to the Vietnamese immigrant women. The insight gained from these healthcare providers' experiences are valuable and might be helpful to healthcare professionals caring for immigrant women of similar ethno-cultural backgrounds. Recommendations for the promotion of breast cancer and cervical cancer screening among Vietnamese women include: (i) effort should be made to recruit Vietnamese-speaking female healthcare professionals for breast and cervical health-promotion programmes; (ii) reduce woman–physicians hierarchical relationship and foster effective doctor–patient communication; (iii) healthcare providers must be aware of their own cultural beliefs, values and attitudes that they bring to their practice; and (iv) more institutional support and resources should be given to both Vietnamese Canadian women and their healthcare providers.     

Older African American women's beliefs, attitudes, and behaviors about breast cancer

Breast cancer poses a greater risk for African American than Caucasian women due to persistent health disparities. To reduce mortality risk, culturally specific knowledge is needed to support and encourage regular breast cancer screening and risk-reduction behaviors in older African American women. The specific aims of this study were to identify social, cultural, and behavioral factors associated with regular participation in breast cancer screening and risk-reduction behaviors; examine health beliefs that may influence regular participation in breast cancer screening and risk-reduction behaviors; and identify perceived facilitators and barriers to regular breast cancer screening and risk-reduction behaviors. African American women older than 65 (N = 57) participated in six focus groups. Analysis of focus group data revealed six major themes: Being Blessed, Cancer as a Death Sentence, Fear/Fear of Disfigurement, Avoiding Finding Out, Beliefs About Breast Cancer, and Tending to One's Family. These themes could be used by health care providers to develop culturally relevant educational initiatives to promote breast health practices and risk-reduction behaviors in this vulnerable population, thus helping reduce breast cancer disparities.

Religion and spirituality: influence on health/risk behavior and cancer screening behavior of African Americans.

In spite of the diversity in the principles, expression and practice, it is believed that significant improvements can occur in the health status of African Americans if health education and outreach efforts are presented and promoted through religious, spiritual and faith-based venues. Several reports published in the peer-reviewed literature address issues related to religion, spirituality and cancer control among African Americans. This growing body of literature describes outcomes of several cancer prevention and control programs designed for and conducted within the African American faith community. However, few efforts have been undertaken to examine the influence of religion and spirituality on health/risk behavior and cancer screening practices of African Americans within the faith community. This report presents the outcomes of an exploratory study undertaken to examine the influence of religion and spirituality on the health/risk behavior and cancer screening practices of African American congregants. Data suggest a need for tailored and targeted health education, outreach and programming among the targeted group of congregants focused specifically on tobacco control, diet and nutrition, exercise and physical activity, weight management, and cancer screening. The same appears to be the case relative to the need for education, outreach and programming focused on communication with primary care providers.     

Lung cancer disparities and African‐Americans

African‐Americans, as historically disadvantaged minorities, have more advanced stages of cancer when diagnosed, lower survival rates, and lower rates of accessing timely care than do Caucasians. Lung cancer incidence and mortality, in particular, are high among African‐Americans. The U.S. Preventive Services Task Force recently released an evidence‐based lung cancer screening technology called low‐dose computerized tomography. High‐risk African‐Americans might benefit greatly from such screening but not many are aware of this technology. Public health nurses can play a key role in increasing awareness of the technology among African‐American communities and encouraging qualified African‐Americans to obtain screening. This study discusses issues with lung cancer and smoking among African‐Americans, a recently released evidence‐based lung cancer screening technology, and implications for public health nurses to enhance uptake of the new screening technology among high‐risk African‐Americans.     

How do rural health care providers and patients view barriers to colorectal cancer screening? Insights from appalachian kentucky

This article reports findings from a qualitative study that explored the attitudes and beliefs concerning colorectal cancer (CRC) screening among patients and health care providers in Appalachian Kentucky. Results from 5 focus groups are discussed here: 3 with primary care providers and 2 with patients. Although there are some areas of agreement, there are marked differences between the perceptions of Appalachian health care providers and participants regarding CRC screening. This article compares and contrasts those perceptions and provides suggestions for culturally competent practice and culturally relevant research to improve CRC screening in this vulnerable population.     

An evaluation of standardized patients in improving clinical breast examinations for military women

There is a need to improve the quality of clinical breast examination (CBE) and breast cancer screening for women. The purpose of this study was to determine whether instructions from a standardized patient to military healthcare providers would increase the quality of CBE and breast cancer screening for military women. The study used a 2-group pretest and posttest experimental design with random assignment by study site. Before and after the intervention, the providers completed a 13-item survey to assess their current breast cancer screening practices and the standardized patient used an investigator-developed checklist to assess the providers' breast cancer screening performance. The survey of breast cancer screening practice scores and the interview and CBE performance scores were analyzed using analysis of covariance with the pretest scores as covariates. Results showed the experimental group made significantly more improvement than did the control group in their total scores on the observational checklist of interview and CBE skills (F = 19.18, P < .001, observed power = 0.99). In conclusion, this method of continuing education was effective with military healthcare providers.     

Prostate cancer screening in African American and Caribbean males: detriment in delay.

Men of the African diaspora are diagnosed with prostate cancer much later than Caucasians and the mortality rate is significantly higher in these groups than among Caucasians. This study investigates health beliefs surrounding prostate health in a sample of African American and Caribbean men and identifies reasons men have for delaying or avoiding prostate screenings. One hundred African American and Caribbean men recruited from three churches, aged 37-89, were surveyed about their health seeking behaviors and knowledge of prostate cancer. Forty-five of these men also attended a seminar on the importance of early detection. Eighty percent of the men revealed they were embarrassed to have digital rectal examinations. Sixty percent feared impotence and incontinence after treatment if diagnosed with cancer. Findings reveal that attention to cultural realities may assist healthcare professionals in planning culturally sensitive educational interventions in the community that may narrow the health disparities gap in this population.     

Screening, surveillance, and prevention of colorectal cancer

Colon cancer screening can be effective, but only with a high-quality program that assures adherence to all elements of the program. There is evidence in the United States of greater acceptance of screening and decreased incidence and mortality of colorectal cancer. Patient education is a key element of any effective screening program. It is hoped that future screening will develop better risk-stratification tools and enable targeting of screening to high-risk individuals.
