In the end, lung cancer left Jerome Grant voiceless, a breathing tube in his windpipe.

He could say nothing when his wife Dawn spoke her last words to him: “I love you, you know that?”

He gave her a thumbs up. Then he closed his eyes and was gone.

The 52-year-old Louisville man was one of about 10,000 Kentuckians a year taken by cancer in a state where the disease consistently kills at the highest rate in the nation. Experts say the biggest culprit is lung cancer, which strikes and kills Kentuckians at rates 50 percent higher than the national average. But Kentucky’s death rates also rank in the Top 10 nationally for breast, colorectal and cervical cancers.

“It’s really been driven by three major things: obesity, smoking and lack of screening,” said Louisville gastroenterologist Dr. Whitney Jones. “Our state is completely inundated with risk factors.”

Smoking, a stubborn vestige of the state’s tobacco legacy, is at the root of most lung cancers, although other environmental causes such as radon play a part as well. Obesity, a risk factor for several cancers, also hits Kentucky hard, afflicting more than three in 10 residents. Poverty, lack of education and doctor shortages mean residents are less likely to get screenings that can find cancer early – or effective treatment. …

Unfortunately, Kentucky has the highest overall cancer incidence and mortality rates in the country compared to all other U.S. states and the District of Columbia. Laura Ungar is a staff writer for the Louisville Courier Journal newspaper. In a recent article titled “Cancer Kills Kentuckians at the Highest Rate”, she makes a strong case that the unusually high cancer burden in Kentucky is related to the high rates of poverty and low educational attainment in the state. But, how are poverty and literacy implicated in the excessively high cancer burden in Kentucky? The answer to this question is not simple. For many years we have observed that cancer risk behaviors such as smoking or not being screened are closely tied to high rates of poverty and low educational attainment. Population-based measures of poverty and literacy are often operationalized as the proportion of the population living below the federal poverty level or the proportion of the population over age 25 with a high school degree. These two measures of socioeconomic destress are also highly correlated. In Kentucky, especially in the Appalachian area of the state, these measure are unusually high. In the U.S. only 14% of the population live below the federal poverty level. In one of the Kentucky Appalachian counties, more than 42% of the population are living below the federal poverty level. In the U.S. more than 85% of the population over age 25 have a high school degree. In some counties in the Appalachian region on Kentucky just over half of the population have a high school degree. Consistent with the association between these measures and increased risk behaviors, the Appalachian region of Kentucky has higher rates of smoking and extraordinarily high rates of lung cancer incidence and mortality.

Lung cancer is clearly the major contributor to the unusually high cancer incidence and mortality rates in Kentucky. In the U.S. lung cancer accounts for 14% of all the new cases occurring annually and 18% of all cancer deaths. In Kentucky, lung cancer accounts for 28% of all new cases occurring annually and well over one third (36%) of all cancer deaths annually. It would be easy to say that the unusually high rates of lung cancer incidence and mortality in Kentucky and especially in the Appalachian area of the state are all due to excessive smoking. However, there are several recent studies that provide strong evidence showing the high rates on lung cancer are not accounted for by smoking alone. To put this issue in context, if a person smokes their risk of lung cancer is 11 to 14 times that of a non-smoker. However, if a person smokes and is also exposed to asbestos, their risk of lung cancer can be 300 times that of a non-smoker. We believe that something like this is accounting for the excessively high lung cancer incidence rates in Appalachian Kentucky. Our own studies have shown that people living in the Appalachian area of Kentucky have elevated levels of arsenic and chromium. Both arsenic and chromium are known lung cancer carcinogens. Therefore, we believe that the excessively high lung cancer incidence rates may be due to the higher rates of smoking in combination with exposure to arsenic and chromium.

Reducing the cancer burden in populations marked by high rates of poverty and low educational attainment can be very challenging. The cancer surveillance program provides tools to identify areas and populations with a high cancer burden. However, to reduce this burden requires a clear understanding of cultural and social barriers, and it requires resources to implement culturally sensitive evidence based interventions programs. We are attempting to do this in Kentucky through our collaborative efforts with partners across the state. By focusing on the areas with the greatest need, we were able to reduce the incidence of colorectal cancer by 24% and the mortality rate by 30% in just seven years. No other state had such a dramatic change in such a short period of time. By continuing to implement culturally sensitive evidence based interventions programs we hope to reduce the cancer burden so it can no longer be said that “Cancer Kills Kentuckians at the Highest Rate”.

I’m pleased to announce the release of this year’s Report to the Nation, an annual collaborative effort by CDC, NCI, ACS, and NAACCR. This 18th “edition” has CDC as the lead agency; however, its success relies upon the tremendous expertise from senior researchers across all the collaborative organizations. Furthermore, no major cancer surveillance report would be possible without the continued dedication and contributions of the state and regional cancer registry staff collecting the data for analysis.

Despite successful reductions in the occurrence and mortality from the most common cancers, some cancers are showing unfavorable trends. Liver cancer, the special focus of the report, has death rates increasing at the highest rate of all cancer sites among men and women, and liver cancer incidence rates are rising at a rate second only to those of thyroid cancer.

Lower Your Chances

A major risk factor for liver cancer is hepatitis C virus (HCV) infection. About 22% of the most common histological type of liver cancer is attributed to HCV. Because rates of chronic HCV infection are most common among people born 1945-1965, CDC recommends one-time testing for HCV for people born during this time. Those who test positive should be referred for appropriate care and treatment. Other strategies for reducing the burden of liver cancer include promoting hepatitis B vaccination, establishing and implementing public health initiatives aimed at reducing unhealthy behaviors such as smoking and excessive alcohol use, and promoting health eating and physical activity to reduce obesity.

Moderate media interest in the topic helped bring attention to the report, including from U.S. News and World Report and multiple national and statewide media outlets. You can read the whole report here. Take a look at the graphics (free for reposting) at www.cdc.gov/cancer.


Abstract

Background: Annual updates on cancer occurrence and trends in the United States are provided through an ongoing collaboration among the American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR). This annual report highlights the increasing burden of liver and intrahepatic bile duct (liver) cancers.

Methods: Cancer incidence data were obtained from the CDC, NCI, and NAACCR; data about cancer deaths were obtained from the CDC’s National Center for Health Statistics (NCHS). Annual percent changes in incidence and death rates (age-adjusted to the 2000 US Standard Population) for all cancers combined and for the leading cancers among men and women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2012 and mortality for 1975-2012) and short-term trends (2008-2012). In-depth analysis of liver cancer incidence included an age-period-cohort analysis and an incidence-based estimation of person-years of life lost because of the disease. By using NCHS multiple causes of death data, hepatitis C virus (HCV) and liver cancer-associated death rates were examined from 1999 through 2013.

Results: Among men and women of all major racial and ethnic groups, death rates continued to decline for all cancers combined and for most cancer sites; the overall cancer death rate (for both sexes combined) decreased by 1.5% per year from 2003 to 2012. Overall, incidence rates decreased among men and remained stable among women from 2003 to 2012. Among both men and women, deaths from liver cancer increased at the highest rate of all cancer sites, and liver cancer incidence rates increased sharply, second only to thyroid cancer. Men had more than twice the incidence rate of liver cancer than women, and rates increased with age for both sexes. Among non-Hispanic (NH) white, NH black, and Hispanic men and women, liver cancer incidence rates were higher for persons born after the 1938 to 1947 birth cohort. In contrast, there was a minimal birth cohort effect for NH Asian and Pacific Islanders (APIs). NH black men and Hispanic men had the lowest median age at death (60 and 62 years, respectively) and the highest average person-years of life lost per death (21 and 20 years, respectively) from liver cancer. HCV and liver cancer-associated death rates were highest among decedents who were born during 1945 through 1965.

Conclusions: Overall, cancer incidence and mortality declined among men; and, although cancer incidence was stable among women, mortality declined. The burden of liver cancer is growing and is not equally distributed throughout the population. Efforts to vaccinate populations that are vulnerable to hepatitis B virus (HBV) infection and to identify and treat those living with HCV or HBV infection, metabolic conditions, alcoholic liver disease, or other causes of cirrhosis can be effective in reducing the incidence and mortality of liver cancer.
