Annual Report to the Nation on the Status of Cancer, 1975-2011, Featuring Incidence of Breast Cancer Subtypes by Race/Ethnicity, Poverty, and State

Background: The American Cancer Society (ACS), Centers for Disease Control and Prevention (CDC), National Cancer Institute (NCI), and North American Association of Central Cancer Registries (NAACCR) collaborate annually to produce updated, national cancer statistics. This Annual Report includes a focus on breast cancer incidence by subtype using new, national-level data. Methods: Population-based cancer trends and breast cancer incidence by molecular subtype were calculated. Breast cancer subtypes were classified using tumor biomarkers for hormone receptor (HR) and human growth factor-neu receptor (HER2) expression. Results: Overall cancer incidence decreased for men by 1.8% annually from 2007 to 2011. Rates for women were stable from 1998 to 2011. Within these trends there was racial/ethnic variation, and some sites have increasing rates. Among children, incidence rates continued to increase by 0.8% per year over the past decade while, like adults, mortality declined. Overall mortality has been declining for both men and women since the early 1990’s and for children since the 1970’s. HR+/HER2- breast cancers, the subtype with the best prognosis, were the most common for all races/ethnicities with highest rates among non-Hispanic white women, local stage cases, and low poverty areas (92.7, 63.51, and 98.69 per 100000 non-Hispanic white women, respectively). HR+/HER2- breast cancer incidence rates were strongly, positively correlated with mammography use, particularly for non-Hispanic white women (Pearson 0.57, two-sided P < .001). Triple-negative breast cancers, the subtype with the worst prognosis, were highest among non-Hispanic black women (27.2 per 100000 non-Hispanic black women), which is reflected in high rates in southeastern states. Conclusions: Progress continues in reducing the burden of cancer in the United States. There are unique racial/ethnic-specific incidence patterns for breast cancer subtypes; likely because of both biologic and social risk factors, including variation in mammography use. Breast cancer subtype analysis confirms the capacity of cancer registries to adjust national collection standards to produce clinically relevant data based on evolving medical knowledge.

Annual Report to the Nation on the Status of Cancer,1975-2012, Featuring the Increasing Incidence of Liver Cancer

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.

Burden of Potentially Human Papillomavirus- associated Cancers of the Oropharynx and Oral Cavity in the US, 1998-2003

As human papillomavirus (HPV) vaccination becomes widely available in the US for cervical cancer prevention, it may also affect the rates of other cancers potentially associated with HPV. The objective of the current study was to describe the incidence rates of oropharyngeal and oral cavity cancers in the US with a focus on anatomic sites potentially associated with HPV infection.

Annual Report to the Nation on the Status of Cancer, 1975–2014, Featuring Survival

Abstract Background: 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) collaborate to provide annual updates on cancer occurrence and trends in the United States. This Annual Report highlights survival rates. Methods: Data were from the CDC- and NCI-funded population-based cancer registry programs and compiled by NAACCR. Trends in age-standardized incidence and death rates for all cancers combined and for the leading cancer types by sex were estimated by joinpoint analysis and expressed as annual percent change. We used relative survival ratios and adjusted relative risk of death after a diagnosis of cancer (hazard ratios [HRs]) using Cox regression model to examine changes or differences in survival over time and by sociodemographic factors. Results: Overall cancer death rates from 2010 to 2014 decreased by 1.8% (95% confidence interval [CI] = –1.8 to –1.8) per year in men, by 1.4% (95% CI = –1.4 to –1.3) per year in women, and by 1.6% (95% CI = –2.0 to –1.3) per year in children. Death rates decreased for 11 of the 16 most common cancer types in men and for 13 of the 18 most common cancer types in women, including lung, colorectal, female breast, and prostate, whereas death rates increased for liver (men and women), pancreas (men), brain (men), and uterine cancers. In contrast, overall incidence rates from 2009 to 2013 decreased by 2.3% (95% CI = –3.1 to –1.4) per year in men but stabilized in women. For several but not all cancer types, survival statistically significantly improved over time for both early and late-stage diseases. Between 1975 and 1977, and 2006 and 2012, for example, five-year relative survival for distant-stage disease statistically significantly increased from 18.7% (95% CI = 16.9% to 20.6%) to 33.6% (95% CI = 32.2% to 35.0%) for female breast cancer but not for liver cancer (from 1.1%, 95% CI = 0.3% to 2.9%, to 2.3%, 95% CI = 1.6% to 3.2%). Survival varied by race/ethnicity and state. For example, the adjusted relative risk of death for all cancers combined was 33% (HR = 1.33, 95% CI = 1.32 to 1.34) higher in non-Hispanic blacks and 51% (HR = 1.51, 95% CI = 1.46 to 1.56) higher in non-Hispanic American Indian/Alaska Native compared with non-Hispanic whites. Conclusions: Cancer death rates continue to decrease in the United States. However, progress in reducing death rates and improving survival is limited for several cancer types, underscoring the need for intensified efforts to discover new strategies for prevention, early detection, and treatment and to apply proven preventive measures broadly and equitably.

Recent trends in U.S. mammography use from 2000-2006 : A population-based analysis

OBJECTIVE We previously reported a decrease in regular mammogram use from 2000 through 2005. To determine whether a downward trend continued in 2006 we re-examined mammography utilization reported in Behavioral Risk Factor Surveillance System data from 2000 through 2006. METHODS Age-adjusted percentages of women who reported having had a mammogram in the past 2 years were estimated by demographic and socioeconomic characteristics. Logistic regression was used to assess the linear time trends. RESULTS The total age-adjusted proportion of all women aged > or =40 years who reported having had a mammogram within the 2 preceding years did not change when comparing data from 2000 (76.5% [95% CI: 75.9-77.0]) to 2006 (76.1% [75.7-76.6]). However, among those with health care coverage, a statistically significant decline in utilization occurred among women age 40 through 59 years, and non-Hispanic white women. CONCLUSIONS A substantial proportion of women are not being screened by mammography as recommended. Recent data suggest that patterns of utilization have leveled off or declined among certain subgroups of women. These data underscore the need to more effectively address current barriers to the utilization of mammography.

Symptoms, diagnoses, and time to key diagnostic procedures among older U.S. women with ovarian cancer.

OBJECTIVE: To examine the types of symptoms and diagnostic procedures reported in Medicare claims 12 months before diagnosis for women with ovarian cancer by stage, and to assess the association between types of symptoms and time to key diagnostic procedures. METHODS: Medicare claims linked to records in the Surveillance, Epidemiology, and End Results (SEER) cancer registries were used to examine diagnosis and procedure codes in 3,250 women aged 65 years and older before a diagnosis of ovarian cancer. RESULTS: Over 81% of women with ovarian cancer had at least one target sign or symptom before diagnosis. Gastrointestinal symptoms such as nausea and vomiting (adjusted odds ratio [aOR] 2.04, 95% confidence interval [CI] 1.40–2.98), and constipation, diarrhea, or other digestive disorders (aOR 2.01, 95% CI 1.58–2.56) were associated with later-stage cancer. In contrast, gynecologic symptoms such as abnormal bleeding (aOR 0.44, 95% CI 0.34–0.58) and genital organ pain (aOR 0.66, 95% CI 0.53–0.80) were associated with earlier disease. Among those with at least one symptom, the rate at which women with gynecologic symptoms went to surgery was higher (hazard ratio 5.5, 95% CI 5.1–6.0) than the rate for women with other nongastrointestinal ovarian cancer–related symptoms. CONCLUSION: Women with ovarian cancer presenting with gastrointestinal symptoms were more likely to have later-stage disease and longer time to key diagnostic tests than those with gynecologic symptoms. Clinicians should be aware of the potential for unresolved gastrointestinal symptoms to be indicators for ovarian cancer. LEVEL OF EVIDENCE: III

Care of long-term cancer survivors: physicians seen by Medicare enrollees surviving longer than 5 years.

Studies have shown that follow‐up care for cancer patients differs by physician specialty, and that coordination between specialists and generalists results in better care. Little is known, however, regarding which specialties of physicians provide care to long‐term cancer survivors.

Mammography Use from 2000 to 2006: State-Level Trends with Corresponding Breast Cancer Incidence Rates

OBJECTIVE Although breast cancer incidence and mortality rates have declined, a significant number of women are affected by this disease each year. Mammography is currently the most effective way to detect breast cancer at an early stage when it is most treatable, but there have been reports of decreasing or stagnant mammography use in the United States. For this study, we investigated the trend in mammography use for each state in comparison with the corresponding breast cancer incidence trend. MATERIALS AND METHODS We used data from the Behavioral Risk Factor Surveillance System for 2000, 2002, 2004, and 2006 to assess the percentage of women >or= 40 years old who reported undergoing mammography within the past 2 years and data from the National Program of Cancer Registries and the Surveillance, Epidemiology, and End Results Program to assess breast cancer incidence rates from 2000 through 2004, the latest year for which data were available at the time of the study. RESULTS The majority of states had a decreasing tendency in mammography use from 2000 to 2006. Only one state had a statistically significant increase in reported mammography use, whereas two states had significant decreases. There was a correlation between breast cancer incidence rates and mammography use by states (r = 0.6), but no correlation between the time trends in breast cancer incidence rates and mammography use was observed. CONCLUSION There was little statistically significant change in self-reported mammography use from 2000 to 2006. Continued monitoring of breast cancer screening practices and breast cancer incidence trends is important for targeting at-risk populations with effective interventions to improve breast cancer prevention and early detection.

Clinical outcomes from the CDC's Colorectal Cancer Screening Demonstration Program

Colorectal cancer remains the second leading cause of cancer‐related deaths among US men and women. Screening rates have been slow to increase, and disparities in screening remain.

Racial and ethnic differences in mammography use among U.S. women younger than age 40

Objective Evidence-based recommendations for routine breast cancer screening suggest that women begin mammography at age 40, although some women receive a mammogram before that age. Little is known about mammography use among younger women, especially with respect to race and ethnicity. Methods We used data from the 2005 National Health Interview Survey to examine racial/ethnic differences in mammography use among U.S. women ages 30–39. We examined descriptive characteristics of women who reported ever having a mammogram, and used logistic regression to estimate associations between race/ethnicity and mammography use among women at average risk for breast cancer. Results Our sample comprised 3,098 women (18% Hispanic, 13% non-Hispanic [NH] black, 69% NH white), of whom 29% reported having ever had a mammogram. NH black women were more likely than NH white women to report ever having a mammogram and receiving multiple mammograms before age 40 among women of average risk. Patterns of mammography use for Hispanic women compared to NH white women varied. Conclusion Findings suggest differential utilization of mammograms by race/ethnicity among women outside current recommendations and of average risk. Future studies should examine the role of practice patterns and patient–provider communication.
