Healthcare Expenditure Burden Among Non-elderly Cancer Survivors, 2008–2012

Introduction: There is increasing concern regarding the financial burden of cancer on patients and their families. This study presents nationally representative estimates of annual out-of-pocket (OOP) burden among non-elderly cancer survivors and assesses the association between high OOP burden and access to care and preventive service utilization. Methods: Using the 2008–2012 Medical Expenditure Panel Survey, 4,271 cancer survivors and 96,780 individuals without a history of cancer were identified, all aged 18–64 years. High annual OOP burden was defined as spending > 20% of annual family income on OOP healthcare costs. Associations between high OOP burden and access to care were evaluated with multivariable logistic regression. Analyses were conducted in 2015. Results: Compared with individuals without a cancer history, cancer survivors were more likely to report a high OOP burden (4.3% vs 3.4%, p=0.009) in adjusted analyses. High OOP burden was more common among cancer survivors who were poor (18.4%), with either public insurance (7.9%) or uninsured (5.7%), and not working (10.2%). Among cancer survivors, high OOP burden was associated with being unable to obtain necessary medical care (19.2% vs 12.5%, p=0.002), delaying necessary medical care (21.6% vs 13.8%, p=0.002), and lower breast cancer screening rates among age-appropriate women (63.2% vs 75.9%, p=0.02). Conclusions: High OOP burden is more common among adults with a cancer history than those without a cancer history. High OOP burden was associated with being unable to obtain necessary medical care, delaying necessary medical care, and lower breast cancer screening rates among women.

Breast Cancer Knowledge and Early Detection among Hispanic Women with a Family History of Breast Cancer along the U.S.-Mexico Border

Background. Breast cancer is the leading cause of cancer-related death among U.S. Hispanic women. Hispanics are less likely than non-Hispanic White women to be diagnosed at an early stage and survive breast cancer. Methods. For this cross-sectional study, we assessed differences in breast cancer knowledge, attitudes, and screening practices between Hispanic women with (FH+) and without (FH-) a family history of breast cancer in three U.S.-Mexico border counties. Results. Among 137 Hispanic women age 40 and older, FH+ women had levels of knowledge and attitudes about breast cancer similar to those of FH- women. FH+ participants were more likely to have ever performed breast self-examinations, although levels of compliance with screening guidelines did not significantly differ between FH+ and FH- groups. Conclusion. U.S. Hispanic women with a family history of breast cancer constitute an at-risk group for which adhering to preventive screening guidelines could substantially reduce breast cancer mortality.

Breast Cancer Knowledge, Attitudes, and Early Detection Practices in United States-Mexico Border Latinas

INTRODUCTION Evidence suggests Latinas residing along the United States-Mexico border face higher breast cancer mortality rates compared to Latinas in the interior of either country. The purpose of this study was to investigate breast cancer knowledge, attitudes, and use of breast cancer preventive screening among U.S. Latina and Mexican women residing along the U.S.-Mexico border. METHODS For this binational cross-sectional study, 265 participants completed an interviewer-administered questionnaire that obtained information on sociodemographic characteristics, knowledge, attitudes, family history, and screening practices. Differences between Mexican (n=128) and U.S. Latina (n=137) participants were assessed by Pearsons chi-square, Fischers exact test, t tests, and multivariate regression analyses. RESULTS U.S. Latinas had significantly increased odds of having ever received a mammogram/breast ultrasound (adjusted odds ratio [OR]=2.95) and clinical breast examination (OR=2.67) compared to Mexican participants. A significantly greater proportion of Mexican women had high knowledge levels (54.8%) compared to U.S. Latinas (45.2%, p<0.05). Age, education, and insurance status were significantly associated with breast cancer screening use. CONCLUSIONS Despite having higher levels of breast cancer knowledge than U.S. Latinas, Mexican women along the U.S.-Mexico border are not receiving the recommended breast cancer screening procedures. Although U.S. border Latinas had higher breast cancer screening levels than their Mexican counterparts, these levels are lower than those seen among the general U.S. Latina population. Our findings underscore the lack of access to breast cancer prevention screening services and emphasize the need to ensure that existing breast cancer screening programs are effective in reaching women along the U.S.-Mexico border.

Do cancer survivors change their prescription drug use for financial reasons? Findings from a nationally representative sample in the United States

There is limited evidence from nationally representative samples about changes in prescription drug use for financial reasons among cancer survivors in the United States.

Toward greater adoption of minimally invasive and nephron-sparing surgical techniques for renal cell cancer in the United States ☆ ☆☆

PURPOSE To examine national, population-based utilization trends of nephron-sparing and minimally invasive techniques for the surgical management of patients with adult renal cell cancer (RCC) in the United States. METHODS Linked data from the National Cancer Institute׳s Patterns of Care studies and the Area Health Resource File were used to evaluate trends of nephron-sparing and minimally invasive techniques in a sample of 1,110 patients newly diagnosed with American Joint Committee on Cancer stages I-II RCC, in 2004 and 2009, who underwent surgery. Descriptive statistics were used to assess patterns of surgery between 2004 and 2009. Multivariable logistic regression analyses were used to evaluate the associations between demographic, clinical, hospital, and area-level health care characteristics with surgery utilization, stratified by the subset of patients who were potentially eligible for partial nephrectomy (PN) vs. radical nephrectomy (RN) and laparoscopic RN (LRN) vs. open RN, respectively. RESULTS Between 2004 and 2009, PN use among stage I patients with tumors≤7cm increased from 29% to 41%, respectively (P = 0.22). Among patients with stage I tumors≤4cm, use of PN significantly increased from 43% in 2004 to 55% in 2009 (P≤0.05). Among patients with stage I tumors>4 to 7cm, laparoscopic partial nephrectomy increased from 8% to 15%, whereas LRN increased from 38% to 69%, between 2004 and 2009 (P = 0.07). Significant increases in LRN use were observed for both stage I (from 43% in 2004 to 58% in 2009; P≤0.05) and stage II patients (from 16% in 2004 to 47% in 2009; P≤0.01). Patients diagnosed at an older age, with larger tumors, non-clear cell RCC and who did not receive treatment in a hospital with residency training were significantly less likely to receive PN vs. RN; whereas, those diagnosed in 2009 with stage I disease were significantly more likely to receive LRN vs. open RN. CONCLUSIONS This study highlights a significant shift toward increased use of nephron-sparing and minimally invasive surgical techniques to treat patients with RCC in the United States. Our findings are among the first population-based reports in which most eligible patients with RCC received PN over RN. In light of the long-standing evidence on the improved patient outcomes, future investigation is warranted to identify the barriers to increased adoption of these nephron-sparing and minimally invasive approaches.

The risk of developing invasive breast cancer in Hispanic women

Current evidence on breast cancer among US Hispanic women indicates a significant public health threat, although few studies have assessed the heterogeneity in breast cancer risk among Hispanics of different origin.

The Impact of Family History of Breast Cancer on Knowledge, Attitudes, and Early Detection Practices of Mexican Women Along the Mexico-US Border

Rates of breast cancer (BC) have increased in Mexico, with the highest incidence and mortality rates observed in the northern Mexican states. This study aimed to describe the BC knowledge, attitudes and screening practices among Mexican women with and without a family history of BC residing along the Mexico-US border, and identify factors associated with screening behaviors. One hundred and twenty eight Mexican women aged 40 and older completed an interviewer-administered questionnaire on sociodemographic characteristics, knowledge, family history, and screening practices. There were no significant differences between Mexican women with and without a family history. Over 60% of women in both groups had never had a mammogram/breast ultrasound, and more than 50% had never obtained a clinical breast exam. Age, marital status, insurance, and breast cancer knowledge significantly influenced BC screening behaviors among Mexican women. Further research is needed to examine other key factors associated with screening utilization, in effort of improving BC rates.

Perceived and Objective Breast Cancer Risk Assessment in Chilean Women Living in an Underserved Area

Background: Breast cancer is the most frequently diagnosed malignancy among Chilean women and an increasingly significant public health threat. This study assessed the accuracy of breast cancer risk perception among underserved, Chilean women. Methods: Women aged 50 to 70 years, with no mammogram during the last 2 years, were randomly selected from a community clinic registry in Santiago, Chile (n = 500). Perceived risk was measured using three methods: absolute risk, comparative risk, and numerical risk. Risk comprehension was measured by comparing womens perceived and objective risk estimates. Multivariate logistic regression was used to assess overestimation of perceived risk. Results: Women at high risk of breast cancer were more likely than average risk women to perceive themselves at high or higher risk, using absolute and comparative risk approaches (P < 0.001). The majority of participants (67%) overestimated their breast cancer risk, on the basis of risk comprehension; although, participants achieved higher accuracy with comparative risk (40%) and absolute risk (31.6%) methods. [Age, breast cancer knowledge and Breast Cancer Risk Assessment Tool (BCRAT) 5-year risk were significantly associated (P < 0.01) with accuracy of perceived risk]. Conclusion: Chilean women residing in an underserved community may not accurately assess their breast cancer risk, although risk perception and level of accuracy differed between perceived risk measures. Comparative and absolute risk methods may better reflect womens interpretation and accuracy of risk perception. Impact: Improving our understanding of Chilean womens perceptions of developing breast cancer may lead to the development of culturally relevant efforts to reduce the breast cancer burden in this population.

Trends in Radiation Therapy among Cancer Survivors in the United States, 2000–2030

Background: Although the number of cancer survivors has increased substantially over the past several decades, the composition of survivors treated with radiotherapy is not well defined. Radiotherapy carries unique long-term toxicity risks for cancer survivors. This study describes the current estimates and future projections of the epidemiology of 5-year cancer survivors who receive radiation therapy. Methods: We used cancer incidence and survival data from the Surveillance, Epidemiology, and End-Results (SEER) database linked to U.S. Census data to estimate the number of 5-year cancer survivors treated with radiation between 2000 and 2030. Future projections assumed continuing incidence and survival trends based on historical rates. Results: In 2016, there were an estimated 3.05 million cancer survivors treated with radiation, accounting for 29% of all cancer survivors. The number of radiation-treated cancer survivors is projected to reach 3.38 million by 2020 and 4.17 million by 2030. In 2016, breast (40%) and prostate cancer (23%) composed the majority of radiation-treated survivors, followed by head and neck cancer (5.8%), lymphoma (5.6%), uterine (3.9%), and rectal cancer (3.8%). The percentage of 70 years or older radiation-treated survivors steadily increased between 2000 and 2030. Conclusions: The next several years are projected to see a large increase in the number of cancer survivors treated with radiation. Impact: This group of cancer survivors has unique needs given the long-term risks of radiation, and increased research and awareness are required to optimize health of this growing population.
