Trends in cancer risk among people with AIDS in the United States 1980-2002.

Abstract: BACKGROUND People with AIDS have heightened cancer risk from immunosuppression. HAART has been available since 1996 and has reduced AIDS-related mortality, but there are few large-scale studies on cancer trends. METHODS AIDS and cancer registries in 11 US regions (1980-2002) were used to identify cancers in 375 933 people with AIDS. Cancer risk relative to the general population was measured using the standardized incidence ratio (SIR), focusing on the 2 years after AIDS onset for those with AIDS in 1990-1995 and 1996-2002 (HAART era). Time trends were assessed with Poisson regression. RESULTS Between 1990-1995 and 1996-2002, risk declined for the two major AIDS-defining cancers: Kaposi sarcoma [(KS) n = 5131; SIR, 22 100 and 3640, respectively; P < 0.0001] and non-Hodgkin lymphoma [(NHL) n = 3412; SIR, 53.2 and 22.6, respectively; P < 0.0001]. Declines began in the 1980s, but risk fell sharply in 1996 and was stable thereafter. Risk of cervical cancer did not change (n = 64; SIR, 4.2 and 5.3, respectively; P = 0.33). Among non-AIDS malignancies, lung cancer was most common, but risk declined between 1990-1995 and 1996-2002 (n = 344; SIR, 3.3 and 2.6, respectively; P = 0.02). Risk of Hodgkin lymphoma increased substantially over the 1990-2002 period (n = 149; SIR, 8.1 and 13.6, respectively; P = 0.003). CONCLUSIONS Dramatic declines in KS and NHL were temporally related to improving therapies, especially introduction of HAART, but those with AIDS remain at marked risk. Among non-AIDS-related cancers, a recent increase in Hodgkin lymphoma was observed.

Cancer risk in people infected with human immunodeficiency virus in the United States

Abstract: Data are limited regarding cancer risk in human immunodeficiency virus (HIV)-infected persons with modest immunosuppression, before the onset of acquired immunodeficiency syndrome (AIDS). For some cancers, risk may be affected by highly active antiretroviral therapy (HAART) widely available since 1996. We linked HIV/AIDS and cancer registries in Colorado, Florida and New Jersey. Standardized incidence ratios (SIRs) compared cancer risk in HIV-infected persons (initially AIDS-free) during the 5-year period after registration with the general population. Poisson regression was used to compare incidence across subgroups, adjusting for demographic factors. Among 57,350 HIV-infected persons registered during 1991-2002 (median CD4 count 491 cells/mm(3)), 871 cancers occurred during follow-up. Risk was elevated for Kaposi sarcoma (KS, SIR 1,300 [n = 173 cases]), non-Hodgkin lymphoma (NHL, 7.3 [n = 203]), cervical cancer (2.9 [n = 28]) and several non-AIDS-defining malignancies, including Hodgkin lymphoma (5.6 [n = 36]) and cancers of the lung (2.6 [n = 109]) and liver (2.7 [n = 14]). KS and NHL incidence declined over time but nonetheless remained elevated in 1996-2002. Incidence increased in 1996-2002 compared to 1991-1995 for Hodgkin lymphoma (relative risk 2.7, 95%CI 1.0-7.1) and liver cancer (relative risk infinite, one-sided 95%CI 1.1-infinity). Non-AIDS-defining cancers comprised 31.4% of cancers in 1991-1995, versus 58.0% in 1996-2002. For KS and NHL, risk was inversely related to CD4 count, but these associations attenuated after 1996. We conclude that KS and NHL incidence declined markedly in recent years, likely reflecting HAART-related improvements in immunity, while incidence of some non-AIDS-defining cancers increased. These trends have led to a shift in the spectrum of cancer among HIV-infected persons.

Health Behaviors of Cancer Survivors: Examining Opportunities for Cancer Control Intervention

Abstract: Purpose A population-based investigation was conducted to examine the prevalence of health behaviors (smoking, alcohol use, physical activity, and cancer screening) of cancer survivors by age, time since diagnosis, and cancer site. Understanding health behaviors of survivors is imperative, as many survivors are living longer and are at risk for cancer recurrence, second cancers, and complications from treatment. Methods Using the National Health Interview Survey, this study examined the prevalence of smoking and alcohol use as well as whether cancer survivors (n = 7,384) are meeting current recommendations for physical activity and cancer screening compared with noncancer controls (n = 121,347). Results Cancer survivors are similar to controls with respect to smoking status and alcohol consumption after adjusting for group differences. However, younger survivors (18 to 40 years) are at greater risk for continued smoking than controls. Survivors are 9% more likely to meet physical activity recommendations ...

Comparison of SEER Treatment Data With Medicare Claims

Abstract: Background: The population-based Surveillance, Epidemiology, and End Results (SEER) registries collect information on first-course treatment, including surgery, chemotherapy, radiation therapy, and hormone therapy. However, the SEER program does not release data on chemotherapy or hormone therapy due to uncertainties regarding data completeness. Activities are ongoing to investigate the opportunity to supplement SEER treatment data with other data sources.

Financial Hardship Associated With Cancer in the United States: Findings From a Population-Based Sample of Adult Cancer Survivors

Abstract: PurposeTo estimate the prevalence of financial hardship associated with cancer in the United States and identify characteristics of cancer survivors associated with financial hardship.MethodsWe identified 1,202 adult cancer survivors diagnosed or treated at ≥ 18 years of age from the 2011 Medical Expenditure Panel Survey Experiences With Cancer questionnaire. Material financial hardship was measured by ever (1) borrowing money or going into debt, (2) filing for bankruptcy, (3) being unable to cover one’s share of medical care costs, or (4) making other financial sacrifices because of cancer, its treatment, and lasting effects of treatment. Psychological financial hardship was measured as ever worrying about paying large medical bills. We examined factors associated with any material or psychological financial hardship using separate multivariable logistic regression models stratified by age group (18 to 64 and ≥ 65 years).ResultsMaterial financial hardship was more common in cancer survivors age 18 to 64 ...

Cancer statistics, 2017

Abstract: Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths that will occur in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival. Incidence data were collected by the Surveillance, Epidemiology, and End Results Program; the National Program of Cancer Registries; and the North American Association of Central Cancer Registries. Mortality data were collected by the National Center for Health Statistics. In 2017, 1,688,780 new cancer cases and 600,920 cancer deaths are projected to occur in the United States. For all sites combined, the cancer incidence rate is 20% higher in men than in women, while the cancer death rate is 40% higher. However, sex disparities vary by cancer type. For example, thyroid cancer incidence rates are 3-fold higher in women than in men (21 vs 7 per 100,000 population), despite equivalent death rates (0.5 per 100,000 population), largely reflecting sex differences in the "epidemic of diagnosis." Over the past decade of available data, the overall cancer incidence rate (2004-2013) was stable in women and declined by approximately 2% annually in men, while the cancer death rate (2005-2014) declined by about 1.5% annually in both men and women. From 1991 to 2014, the overall cancer death rate dropped 25%, translating to approximately 2,143,200 fewer cancer deaths than would have been expected if death rates had remained at their peak. Although the cancer death rate was 15% higher in blacks than in whites in 2014, increasing access to care as a result of the Patient Protection and Affordable Care Act may expedite the narrowing racial gap; from 2010 to 2015, the proportion of blacks who were uninsured halved, from 21% to 11%, as it did for Hispanics (31% to 16%). Gains in coverage for traditionally underserved Americans will facilitate the broader application of existing cancer control knowledge across every segment of the population.

Global Patterns of Cancer Incidence and Mortality Rates and Trends

Abstract: While incidence and mortality rates for most cancers (including lung, colorectum, female breast, and prostate) are decreasing in the United States and many other western countries, they are increasing in several less developed and economically transitioning countries because of adoption of unhealthy western lifestyles such as smoking and physical inactivity and consumption of calorie-dense food. Indeed, the rates for lung and colon cancers in a few of these countries have already surpassed those in the United States and other western countries. Most developing countries also continue to be disproportionately affected by cancers related to infectious agents, such as cervix, liver, and stomach cancers. The proportion of new cancer cases diagnosed in less developed countries is projected to increase from about 56% of the world total in 2008 to more than 60% in 2030 because of the increasing trends in cancer rates and expected increases in life expectancy and growth of the population. In this review, we describe these changing global incidence and mortality patterns for select common cancers and the opportunities for cancer prevention in developing countries.
