[Towards informed choice: design and results of projects on (cancer) screening funded by the Federal Ministry of Health]

There has been a gradual paradigm shift in the area of screening and early detection of diseases. For many years, the sole focus of public health policies was increasing the uptake rates in screening programs. However, today there is an increasing awareness of the importance of informed decision making -- particularly in the area of screening. The provision of high-quality, evidence-based, and comprehensive information on benefit and harm is an important approach in achieving this objective. The current paper presents a project that was funded by the Federal Ministry of Health. It examines whether existing information material is appropriate to support informed decision making. In the first phase of the project, different screening procedures were assessed systematically and compared using several indicators. Based on the results of an expert workshop, the subsequent research activities focused on colorectal cancer (CRC) screening as one example. Phase II included the systematic search and assessment of print media, e.g., flyers and brochures, while phase III applied the same methods to websites on CRC screening. The information material was analyzed with a mix of methods, involving both experts and users. Finally, the results were presented and discussed with the authors/providers of the information material. Based on the results of this project, the Federal Center for Health Education developed a module on CRC screening for an Internet platform on women's health that is currently being evaluated. In sum, this research project contributes to the development of evidence-based and balanced information as well as informed decision making.

Strategies to improve repeat fecal occult blood testing cancer screening

BACKGROUND

A comparative effectiveness intervention by this team improved initial fecal occult blood testing (FOBT) rates from 3% to 53% among community clinic patients. The purpose of this study was to evaluate the effectiveness and costs associated with a literacy-informed intervention on repeat FOBT testing.

METHODS

Between 2008 and 2011, a three-arm quasi-experiential comparative effectiveness evaluation was conducted in eight community clinics in Louisiana. Clinics were randomly assigned to receive: enhanced care, a screening recommendation, and FOBT kit annually; a brief educational intervention where patients additionally received a literacy appropriate pamphlet and simplified FOBT instructions; or nurse support where a nurse manager provided the education and followed up with phone support. In year 2, all materials were mailed. The study consisted of 461 patients, ages 50 to 85 years, with a negative initial FOBT.

RESULTS

Repeat FOBT rates were 38% enhanced care, 33% education, and 59% with nurse support (P = 0.017). After adjusting for age, race, gender, and literacy, patients receiving nurse support were 1.46 times more likely to complete repeat FOBT screening than those receiving education [95% confidence interval (CI), 1.14-1.06; P = 0.002] and 1.45 times more likely than those in enhanced care but this was not significant (95% CI, 0.93-2.26; P = 0.10). The incremental cost per additional person screened was $2,450 for nurse over enhanced care.

CONCLUSION

A mailed pamphlet and FOBT with simplified instructions did not improve annual screening.

IMPACT

Telephone outreach by a nurse manager was effective in improving rates of repeat FOBT, yet this may be too costly for community clinics.

Cancer mortality in Europe, 2005-2009, and an overview of trends since 1980

BACKGROUND

After a peak in the late 1980s, cancer mortality in Europe has declined by ~10% in both sexes up to the early 2000s. We provide an up-to-date picture of patterns and trends in mortality from major cancers in Europe.

METHODS

We analyzed cancer mortality data from the World Health Organization for 25 cancer sites and 34 European countries (plus the European Union, EU) in 2005-2009. We computed age-standardized rates (per 100,000 person-years) using the world standard population and provided an overview of trends since 1980 for major European countries, using joinpoint regression.

RESULTS

Cancer mortality in the EU steadily declined since the late 1980s, with reductions by 1.6% per year in 2002-2009 in men and 1% per year in 1993-2009 in women. In western Europe, rates steadily declined over the last two decades for stomach and colorectal cancer, Hodgkin lymphoma, and leukemias in both sexes, breast and (cervix) uterine cancer in women, and testicular cancer in men. In central/eastern Europe, mortality from major cancer sites has been increasing up to the late 1990s/early 2000s. In most Europe, rates have been increasing for lung cancer in women and for pancreatic cancer and soft tissue sarcomas in both sexes, while they have started to decline over recent years for multiple myeloma. In 2005-2009, there was still an over twofold difference between the highest male cancer mortality in Hungary (235.2/100,000) and the lowest one in Sweden (112.9/100,000), and a 1.7-fold one in women (from 124.4 in Denmark to 71.0/100,000 in Spain).

CONCLUSIONS

With the major exceptions of female lung cancer and pancreatic cancer in both sexes, in the last quinquennium, cancer mortality has moderately but steadily declined across Europe. However, substantial differences across countries persist, requiring targeted interventions on risk factor control, early diagnosis, and improved management and pharmacological treatment for selected cancer sites.

Contrasts in rural and urban barriers to colorectal cancer screening

OBJECTIVES

To contrast barriers to colon cancer (CRC) screening and Fecal Occult Blood Test (FOBT) completion between rural and urban safety-net patients.

METHODS

Interviews were administered to 972 patients who were not up-to-date with screening.

RESULTS

Rural patients were more likely to believe it was helpful to find CRC early (89.7% vs 66.1%, p < .0001), yet were less likely to have received a screening recommendation (36.4% vs. 45.8%, p = .03) or FOBT information (14.5% vs 32.3%, p < .0001) or to have completed an FOBT (22.0% vs 45.8%, p < .0001).

CONCLUSIONS

Interventions are needed to increase screening recommendation, education and completion, particularly in rural areas.

Meeting the global demands of epidemiologic transition - the indispensable role of cancer prevention

The number of new cancer cases each year is projected to rise worldwide by about 70% by 2030 due to demographic changes alone, with the largest increases in the lower-income countries. Wider adoption of specific aspects of westernized lifestyles would translate to still greater increases in certain cancer types. In many countries the burden of cancer and other non-communicable diseases will add to communicable diseases and malnutrition to impose a "double burden" on the poorest. These trends represent major challenges to health, poverty, sustainable development and equality. Prevention is, however, possible based on implementing existing knowledge about risk factors and the natural history of the disease. Both primary and secondary cancer prevention offer therefore many opportunities to combat the projected increases. Tobacco control, reductions in obesity and physical inactivity, reduced consumption of alcohol, vaccination against hepatitis B and human papilloma viruses, safe sex, avoidance of environmental and occupational carcinogens and excessive sun exposure as well as the early detection and screening for breast, cervix and colorectal cancers would all make significant contributions. At the same time, for a number of major cancers (e.g., colon, prostate, kidney, pancreas, brain, lympho-haematological malignancies) research is needed to identify as yet unknown risk factors whilst for existing prevention strategies additional work is needed on their implementation into health services. Finally, there is a remarkable opportunity for advances in understanding the molecular basis of carcinogenesis to provide new tools and insights into aetiology and prevention. It is only by complementing efforts to improve treatment with those aimed at prevention that the impending epidemic of this disease can be addressed.
