RESUMO
OBJECTIVE: To examine trends, characteristics, and outcomes of donor oocyte embryo transfer cycles by original oocyte and resultant embryo state and determine whether oocyte state (fresh or frozen) is differentially associated with clinical pregnancy, live birth, and term, healthy birthweight neonates among singleton live births. DESIGN: Retrospective cohort study. SETTING: National study. PATIENT(S): Patients undergoing donor oocyte embryo transfer cycles in the United States reporting to the National Assisted Reproductive Technology Surveillance System from 2013 to 2020. INTERVENTION(S): Original donor oocyte and resultant embryo state (fresh or frozen). MAIN OUTCOME MEASURE(S): Annual numbers and proportions of total donor oocyte embryo transfer cycles stratified by oocyte and embryo state and single embryo transfer cycles resulting in the live birth of term (≥37 weeks gestation), healthy birthweight (≥2,500 g) singletons during 2013-2020. Rates of live birth and term, healthy birthweight neonates among singleton live births for 2018-2020 are also reported. Relative risks examine associations between donor oocyte state and live birth and term, healthy birthweight neonates among singleton live births resulting from donor oocyte embryo transfer cycles. RESULT(S): From 2013 to 2020, there were 135,085 donor oocyte embryo transfer cycles, of which the proportions increased for frozen embryos (42.3%-76.6%), fresh embryos using frozen donor oocytes (19.9%-68.3%) and single embryo transfers (36.4%-85.5%). During 2018-2020, there were 48,679 donor oocyte embryo transfer cycles. Rates of live birth were lower with frozen compared with fresh donor oocytes for both fresh (46.2%, 55.9%; adjusted relative risk [aRR], 0.83; 95% confidence interval [CI], 0.79-0.87) and frozen (41.3%, 45.8%; aRR, 0.94; 95% CI, 0.91-0.98) embryo transfer cycles. Among singleton live births, rates of delivering a term, healthy birth weight neonate were similar for frozen compared with fresh donor oocyte transfer cycles among fresh (77.3, 77.2%; aRR, 1.01; 95% CI, 0.98-1.03) and frozen (75.6, 75.1%; aRR, 1.02; 95% CI, 0.99-1.04) embryos. CONCLUSION(S): In this national study of donor oocyte embryo transfer cycles, frozen embryo transfers, fresh embryo transfers using frozen oocytes, and single embryo transfers increased. Although frozen compared with fresh oocytes were associated with a slightly reduced rate of live birth, rates of term, healthy birthweight neonates among singleton live births were comparable between donor oocyte states.
RESUMO
OBJECTIVE: To describe characteristics, trends, and outcomes of international gestational surrogacy cycles in the United States (US). DESIGN: Retrospective cohort study. SETTING: All assisted reproductive technology cycles in the US reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting Systems that included an embryo transfer to a gestational carrier from 2014 to 2020. PATIENTS: International vs. US intended parents. MAIN OUTCOME MEASURES: Cycle characteristics, geographic distributions, and obstetrical outcomes. RESULTS: Of 40,177 embryo transfers to a gestational carrier from 2014 to 2020, 32% were for international intended parents. The number and percent of international intended parents' gestational carrier cycles increased each year from 2014 (n = 2758, 22.0%) to 2019 (n = 4905, 39.8%) with a decrease in 2020 (n = 4713, 31.8%). Compared with cycles for US intended parents, there was a larger decrease in gestational carrier cycles between 2019 and 2020 for international intended parents (3.9% vs. 32.2%). International intended parents were more likely to be male sex (41.3% vs. 19.6%), older than 42 years (33.9% vs. 26.2%) and identify as Asian race (65.6% vs. 16.5%). International intended parents were largely from China (41.7%), followed by France (9.2%) and Spain (8.5%). Gestational carriers for international intended parents were more commonly younger than 30 years (42.8% vs. 29.1%) and identified as Hispanic race (28.6% vs. 11.7%) compared with gestational carriers for US intended parents. Cycles with international intended parents were more likely to use donor eggs (67.1% vs. 43.5%), intracytoplasmic sperm injection (72.8% vs. 55.4%), and preimplantation genetic testing (79.0% vs. 55.8%). Cycles with international and US intended parents had similar obstetrical outcomes, including live birth (adjusted risk ratio 1.01, 95% confidence interval 1.00-1.03) and multiple pregnancy (adjusted risk ratio 1.00, 95% confidence interval 0.94-1.06) rates. CONCLUSION: An increasing number of international intended parents are utilizing gestational surrogacy in the US and more frequently using cost-enhancing specialized treatment techniques. This increase is potentially because of restrictive international commercial surrogacy laws and the increased availability of reproductive medical expertise. Given this growing demographic, continued examination of the volume of cross-border reproductive treatment, as well as the legal and ethical considerations, is warranted.

OBJECTIVE: To examine whether the (1) scope of state-mandated insurance coverage for assisted reproductive technology (ART) and (2) proportion of the population eligible for this coverage are associated with reductions in racial/ethnic inequities in ART utilization. DESIGN: National cross-sectional, ecologic study. SUBJECTS: We employed estimates from the US Census Bureau of all women 20-44 years of age living in the US in 2018. Data on the number of women who initiated an ART cycle during that year that were reported to the US Centers for Disease Control and Prevention were obtained from the National ART Surveillance System. EXPOSURE: State mandates were classified according to the scope of required coverage for fertility services: Comprehensive, Limited, and No Mandate. MAIN OUTCOME MEASURES: Race and ethnic-specific ART utilization rates, defined as the number of women undergoing ≥1 ART cycles per 10,000 women, were the primary outcomes. As state mandates do not apply to all insurance plans, Comprehensive Mandate utilization rates were recalculated using denominators corrected for the estimated proportions of populations eligible for coverage. RESULTS: Across all mandate categories, Non-Hispanic (NH) Asian and NH White populations had the highest ART utilization rates, whereas the lowest rates were among Hispanic, NH Black, and NH Other/Multiple Races populations. Compared with the NH Asian reference group, the NH Black population had smaller inequities in the Comprehensive Mandate group than the No Mandate group (rate ratio [RR 0.33 [0.28-0.38] vs. RR 0.23 [0.22-0.24]). Using the Comprehensive Mandate group for each race/ethnicity as the reference, the NH Black and NH Other/Multiple Races populations showed the largest relative differences in utilization between the No Mandate and Comprehensive Mandate groups (RR 0.39 [0.37-0.41] and 0.33 [0.28-0.38], respectively). Within the Comprehensive Mandate group, the disparities in the Hispanic and NH Black populations moved toward the null after correcting for state-mandated insurance eligibility. CONCLUSIONS: Racial/ethnic inequities in ART utilization were reduced in states with comprehensive infertility coverage mandates. Inequities were further attenuated after correcting for mandate eligibility. Mandates alone, however, were not sufficient to eliminate disparities. These findings can inform future strategies aimed at improving ART access under a social justice framework.

Background: Missing race/ethnicity data are common in many surveillance systems and registries, which may limit complete and accurate assessments of racial and ethnic disparities. Centers for Disease Control and Prevention's National Assisted Reproductive Technology (ART) Surveillance System (NASS) has a congressional mandate to collect data on all ART cycles performed by fertility clinics in the United States and provides valuable information on ART utilization and treatment outcomes. However, race/ethnicity data are missing for many ART cycles in NASS. Materials and Methods: We multiply imputed missing race/ethnicity data using variables from NASS and additional zip code-level race/ethnicity information in U.S. Census data. To evaluate imputed data quality, we generated training data by imposing missing values on known race/ethnicity under missing at random assumption, imputed, and examined the relationship between race/ethnicity and the rate of stillbirth per pregnancy. Results: The distribution of imputed race/ethnicity was comparable to the reported one with the largest difference of 0.53% for non-Hispanic Asian. Our imputation procedure was well calibrated and correctly identified that 89.91% (standard error = 0.18) of known race/ethnicity values on average in training data. Compared to complete-case analysis, using multiply imputed data reduced bias of parameter estimates (the range of bias for stillbirth per pregnancy across race/ethnicity groups is 0.02%-0.18% for imputed data analysis, versus 0.04%-0.66% for complete-case analysis) and yielded narrower confidence intervals. Conclusions: Our results underscore the importance of collecting complete race/ethnicity information for ART surveillance. However, when the missingness exists, multiply imputed race/ethnicity can improve the accuracy and precision of health outcomes estimated across racial/ethnic groups.

Objective: To estimate uptake of influenza, tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap), and COVID-19 vaccines during pregnancy and describe vaccine attitudes and beliefs among predominantly racial and ethnic minority individuals delivering at a publicly funded hospital. Methods: We collected survey and electronic medical record data for English-speaking postpartum individuals who delivered a live-born infant from July 7, 2022, through August 21, 2022, and agreed to participate in our study. The 58-item survey included questions about general vaccine attitudes and beliefs as well as vaccine-specific questions. We calculated rates of influenza, Tdap, and COVID-19 vaccinations and compared distributions of survey responses by number (no vaccines, one vaccine, or two or three of the recommended vaccines) and type of vaccines received during pregnancy. Results: Of the 231 eligible individuals, 125 (54.1%) agreed to participate. Rates of influenza, Tdap, and COVID-19 vaccination were 18.4%, 48.0%, and 5.6% respectively. A total of 61 (48.8%) did not receive any recommended vaccines during pregnancy, 40 (32.0%) received one vaccine, and 24 (19.0%) received two or three vaccines. Approximately 66.1% of the no vaccine group, 81.6% of the one vaccine group, and 87.5% of the two or three vaccine group strongly agreed or agreed that they trusted the vaccine information provided by their obstetrician or midwife. While most (>69.2%) agreed that the vaccine-preventable diseases were dangerous for pregnant women, only 24.0%, 29.3%, and 40.3% agreed that they were worried about getting influenza, whooping cough, or COVID-19, respectively, while pregnant. Discussion: Vaccine uptake in our population was low and may be due, in part, to low perceived susceptibility to vaccine-preventable diseases. Obstetricians and midwives were trusted sources of vaccine information, suggesting that enhanced communication strategies could be critical for addressing maternal vaccine hesitancy, particularly in communities of color justifiably affected by medical mistrust.
RESUMO
BACKGROUND: Insurance coverage for fertility services may reduce the financial burden of high-cost fertility care such as assisted reproductive technology and improve its utilization. Patients who exit care after failing to reach their reproductive goals report higher rates of mental health problems and a lower sense of well-being. It is important to understand the relationship between state-mandated insurance coverage for fertility services and assisted reproductive technology care discontinuation. OBJECTIVE: This study aimed to assess whether state-mandated insurance coverage for fertility services is associated with lower rates of care discontinuation after an initial assisted reproductive technology cycle that did not result in a live birth. STUDY DESIGN: This is a retrospective, population-based cohort study using data from United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2016 and 2018. Patients who began their first autologous assisted reproductive technology cycle during 2016 and 2017 and did not have a live birth were included. We describe the rate of assisted reproductive technology care discontinuation (no additional cycle within 12 months of the previous cycle's date of failure). Multivariable analyses were conducted to evaluate factors independently associated with care discontinuation, including the scope of fertility services included in state coverage mandate at assisted reproductive technology cycle initiation that were as follows: comprehensive (≥3 assisted reproductive technology cycles), limited (1, 2, or an unspecified number of assisted reproductive technology cycles), mandate not including assisted reproductive technology, and no mandate. RESULTS: Among 91,324 patients who underwent their first autologous assisted reproductive technology cycle that did not result in live birth, 24,072 (26.4%) discontinued care. Compared with patients who lived in states with mandates for comprehensive assisted reproductive technology coverage, those in states with mandates for fertility services coverage that did not include assisted reproductive technology or states with no mandate were 46% (adjusted relative risk, 1.46; 95% confidence interval, 1.31-1.63) and 26% (adjusted relative risk, 1.26; 95% confidence interval, 1.15-1.39) more likely to discontinue care, respectively, after controlling for patient and cycle characteristics. Increasing patient age, distance from clinic ≥50 miles, previous live birth, fewer oocytes retrieved, and not having embryos cryopreserved were also associated with higher rates of discontinuation. Non-Hispanic Black, non-Hispanic Asian, and Hispanic patients had higher rates of care discontinuation than non-Hispanic White patients regardless of the existence or scope of state-mandated assisted reproductive technology coverage. CONCLUSION: Comprehensive state-mandated insurance coverage for assisted reproductive technology is associated with lower rates of assisted reproductive technology care discontinuation.

BACKGROUND: In 2016, the US Food and Drug Administration amended existing regulations to increase access to donated embryos for reproductive use. Current information regarding the characteristics and outcomes of embryo donation cycles could benefit patients and providers during counseling and decision making. OBJECTIVE: This study aimed to examine the trends in the utilization of embryo donation, pregnancy rates, and live birth rates per transfer between 2004 and 2019 and to describe the recipients of donated embryos and outcomes of frozen donated embryo transfer cycles during the most recent time period, that is, 2016 to 2019. STUDY DESIGN: We conducted a retrospective, population-based cohort study of frozen donated embryo transfer cycles in United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2004 to 2019. The trends in the annual number and proportion of frozen donated embryo transfers, pregnancy rates, and live birth rates from 2004 to 2019 were described. During 2016 to 2019, the rates of cycle cancellation, pregnancy, miscarriage, live birth, singleton birth, and good perinatal outcome (delivery ≥37 weeks, birthweight ≥2500 g) of frozen donated embryo transfers were also calculated. Transfer and pregnancy outcomes stratified by oocyte source age at the time of oocyte retrieval were also described. RESULTS: From 2004 to 2019, there were 21,060 frozen donated embryo transfers in the United States, resulting in 8457 live births. During this period, the annual number and proportion of frozen donated embryo transfers with respect to all transfers increased, as did the pregnancy rate and live birth rate. Among all initiated cycles during 2016 to 2019, the cancellation rate was 8.2%. Among 8773 transfers with known outcomes, 4685 (53.4%) resulted in pregnancy and 3820 (43.5%) in live birth. Among all pregnancies, 814 (17.4%) resulted in miscarriage. Among all live births, 3223 (84.4%) delivered a singleton, of which 2474 (76.8%) had a good perinatal outcome. The clinical pregnancy rate and live birth rate per frozen donated embryo transfer decreased with increasing age of oocyte source. CONCLUSION: The outcomes of embryo donation cycles reported in this national cohort may aid patients and providers when considering the use of donated embryos.

Objective: To examine trends of frozen embryo transfer (FET) proportions and large-for-gestational-age (LGA) incidence and determine risk factors for LGA infants after FET. Design: Retrospective cohort study. Setting: Not applicable. Patients: Frozen embryo transfer cycles. Interventions: None. Main Outcome Measures: Singleton LGA infant. Results: The percentage of FETs increased from 20%-74% of transfers, whereas the rate of LGA among FET singleton births decreased from 18%-12% during 2004-2018. In a subanalysis of 127,525 FET-associated singleton live births during 2016-2018, patient factors associated with LGA were higher-than-normal maternal body mass index (body mass index [BMI], 25.0-29.9 kg/m2; adjusted relative risk [aRR], 1.31; 95% confidence interval [CI], 1.26-1.36; BMI, 30.0-34.9 kg/m2; aRR, 1.48; 95% CI, 1.41-1.55; and BMI, >35 Kg/m2; aRR, 1.68; 95% CI, 1.59-1.77) and ≥1 prior birth vs. none. Low maternal BMI (<18.5 vs. 18.5-24.9 kg/m2) and cycles involving patients who were non-Hispanic (NH) Asian/Native Hawaiian/Pacific Islander, NH Black, or Hispanic (compared with NH White) were at lower risk of LGA infants. Cycle factors associated with LGA included gestational carrier use (aRR, 1.25; 95% CI, 1.16-1.34) and donor sperm (aRR, 1.17; 95% CI, 1.10-1.25). Conclusions: Although the number and proportion of FET cycles increased from 2004-2018, the rate of LGA after FET decreased. Maternal BMI, parity, and race/ethnicity were the strongest risk factors for LGA infants after FET.
RESUMO
BACKGROUND: This study was aimed at examining the risks of subsequent primary cancers (SPCs) among breast cancer survivors by hormone receptor (HR) status and age at diagnosis. METHODS: Data from 12 Surveillance, Epidemiology, and End Results registries were used to identify 431,222 breast cancer survivors (at least 1 year) diagnosed between the ages of 20 and 84 years from 1992 to 2015. Risks of SPCs were measured as the standardized incidence ratio (SIR) and the excess absolute risk (EAR) per 10,000 person-years. Poisson regression was used to test the difference in SIRs by HR status. RESULTS: In comparison with the general population, the risk of new cancer diagnoses among survivors was 20% higher for those with HR-positive cancers (SIR, 1.20; 95% confidence interval [CI], 1.19-1.21; EAR, 23.3/10,000 person-years) and 44% higher for those with HR-negative cancers (SIR, 1.44; 95% CI, 1.41-1.47; EAR, 45.2/10,000 person-years), with the risk difference between HR statuses statistically significant. The higher risk after HR-negative cancer was driven by acute nonlymphocytic leukemia and breast, ovarian, peritoneal, and lung cancers. By age at diagnosis, the total EAR per 10,000 person-years ranged from 15.8 (95% CI, 14.1-17.5; SIR, 1.11) among late-onset (age, 50-84 years) HR-positive survivors to 69.4 (95% CI, 65.1-73.7; SIR, 2.24) among early-onset (age, 20-49 years) HR-negative survivors, with subsequent breast cancer representing 73% to 80% of the total EAR. After breast cancer, the greatest EARs were for ovarian cancer among early-onset HR-negative survivors, lung cancer among early- and late-onset HR-negative survivors, and uterine corpus cancer among late-onset HR-positive survivors. CONCLUSIONS: Risks of SPCs after breast cancer differ substantially by subtype and age. This suggests that more targeted approaches for cancer prevention and early-detection strategies are needed in survivorship care planning.

The American Cancer Society (ACS) recommends that individuals with a cervix initiate cervical cancer screening at age 25 years and undergo primary human papillomavirus (HPV) testing every 5 years through age 65 years (preferred); if primary HPV testing is not available, then individuals aged 25 to 65 years should be screened with cotesting (HPV testing in combination with cytology) every 5 years or cytology alone every 3 years (acceptable) (strong recommendation). The ACS recommends that individuals aged >65 years who have no history of cervical intraepithelial neoplasia grade 2 or more severe disease within the past 25 years, and who have documented adequate negative prior screening in the prior 10 years, discontinue all cervical cancer screening (qualified recommendation). These new screening recommendations differ in 4 important respects compared with the 2012 recommendations: 1) The preferred screening strategy is primary HPV testing every 5 years, with cotesting and cytology alone acceptable where access to US Food and Drug Administration-approved primary HPV testing is not yet available; 2) the recommended age to start screening is 25 years rather than 21 years; 3) primary HPV testing, as well as cotesting or cytology alone when primary testing is not available, is recommended starting at age 25 years rather than age 30 years; and 4) the guideline is transitional, ie, options for screening with cotesting or cytology alone are provided but should be phased out once full access to primary HPV testing for cervical cancer screening is available without barriers. Evidence related to other relevant issues was reviewed, and no changes were made to recommendations for screening intervals, age or criteria for screening cessation, screening based on vaccination status, or screening after hysterectomy. Follow-up for individuals who screen positive for HPV and/or cytology should be in accordance with the 2019 American Society for Colposcopy and Cervical Pathology risk-based management consensus guidelines for abnormal cervical cancer screening tests and cancer precursors.

Compared with white women, black women have higher incidence rates for triple-negative breast cancer but lower rates for hormone receptor (HR)-positive cancers in the United States. Whether similar racial difference occurs in male breast cancer is unclear. We examined racial differences in incidence rates of breast cancer subtypes defined by HR and human epidermal growth factor receptor 2 (HER2) by sex using nationwide data from 2010 to 2016. Among men, rates were higher in blacks than whites for all subtypes, with the black-to-white incidence rate ratios of 1.41 (95% confidence interval [CI ]= 1.32 to 1.50) for HR+/HER-, 1.65 (95% CI = 1.40 to 1.93) for HR+/HER2+, 2.62 (95% CI = 1.48 to 4.43) for HR-/HER2+, and 2.27 (95% CI = 1.67 to 3.03) for triple-negative subtype. Conversely, among women, rates in blacks were 21% lower for HR+/HER2- and comparable for HR+/HER2+ but 29% and 93% higher for HR-/HER2+ and triple-negative subtypes, respectively. Future studies are needed to identify contributing factors to the dissimilar racial patterns in breast cancer subtype incidence between men and women.
RESUMO
This article is the American Cancer Society's biennial update on female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Over the most recent 5-year period (2012-2016), the breast cancer incidence rate increased slightly by 0.3% per year, largely because of rising rates of local stage and hormone receptor-positive disease. In contrast, the breast cancer death rate continues to decline, dropping 40% from 1989 to 2017 and translating to 375,900 breast cancer deaths averted. Notably, the pace of the decline has slowed from an annual decrease of 1.9% during 1998 through 2011 to 1.3% during 2011 through 2017, largely driven by the trend in white women. Consequently, the black-white disparity in breast cancer mortality has remained stable since 2011 after widening over the past 3 decades. Nevertheless, the death rate remains 40% higher in blacks (28.4 vs 20.3 deaths per 100,000) despite a lower incidence rate (126.7 vs 130.8); this disparity is magnified among black women aged <50 years, who have a death rate double that of whites. In the most recent 5-year period (2013-2017), the death rate declined in Hispanics (2.1% per year), blacks (1.5%), whites (1.0%), and Asians/Pacific Islanders (0.8%) but was stable in American Indians/Alaska Natives. However, by state, breast cancer mortality rates are no longer declining in Nebraska overall; in Colorado and Wisconsin in black women; and in Nebraska, Texas, and Virginia in white women. Breast cancer was the leading cause of cancer death in women (surpassing lung cancer) in four Southern and two Midwestern states among blacks and in Utah among whites during 2016-2017. Declines in breast cancer mortality could be accelerated by expanding access to high-quality prevention, early detection, and treatment services to all women.

Adults aged 85 years and older, the "oldest old," are the fastest-growing age group in the United States, yet relatively little is known about their cancer burden. Combining data from the National Cancer Institute, the North American Association of Central Cancer Registries, and the National Center for Health Statistics, the authors provide comprehensive information on cancer occurrence in adults aged 85 years and older. In 2019, there will be approximately 140,690 cancer cases diagnosed and 103,250 cancer deaths among the oldest old in the United States. The most common cancers in these individuals (lung, breast, prostate, and colorectum) are the same as those in the general population. Overall cancer incidence rates peaked in the oldest men and women around 1990 and have subsequently declined, with the pace accelerating during the past decade. These trends largely reflect declines in cancers of the prostate and colorectum and, more recently, cancers of the lung among men and the breast among women. We note differences in trends for some cancers in the oldest age group (eg, lung cancer and melanoma) compared with adults aged 65 to 84 years, which reflect elevated risks in the oldest generations. In addition, cancers in the oldest old are often more advanced at diagnosis. For example, breast and colorectal cancers diagnosed in patients aged 85 years and older are about 10% less likely to be diagnosed at a local stage compared with those diagnosed in patients aged 65 to 84 years. Patients with cancer who are aged 85 years and older have the lowest relative survival of any age group, with the largest disparities noted when cancer is diagnosed at advanced stages. They are also less likely to receive surgical treatment for their cancers; only 65% of breast cancer patients aged 85 years and older received surgery compared with 89% of those aged 65 to 84 years. This difference may reflect the complexities of treating older patients, including the presence of multiple comorbidities, functional declines, and cognitive impairment, as well as competing mortality risks and undertreatment. More research on cancer in the oldest Americans is needed to improve outcomes and anticipate the complex health care needs of this rapidly growing population.

BACKGROUND: A previous study reported that Eastern-African-born black women in the United States had lower prevalence of estrogen receptor-negative breast cancer than those in US-born and Western-African-born black women, among whom the prevalence was similar. It is unknown whether the prevalence of triple-negative breast cancer (negative for estrogen receptor, progesterone receptor, and human epidermal growth factor 2 receptor) among black women in the United States differs similarly by birthplace. METHODS: In the National Program of Cancer Registries and US Cancer Statistics, the authors identified 65,211 non-Hispanic black women who were diagnosed with invasive breast cancer from 2010 through 2015 and were recorded as being born in the United States, East Africa, West Africa, or the Caribbean. The prevalence of triple-negative and hormone receptor-negative breast cancer (negative for estrogen receptor and progesterone receptor) among each group of foreign-born black women was compared with that among US-born black women and was expressed as the adjusted prevalence rate ratio, accounting for sociodemographic and tumor characteristics. Analyses were stratified by Census region, and region-specific estimates were summarized using random-effects meta-analyses. RESULTS: Compared with US-born black women, the prevalence rate ratio of triple-negative breast cancer was 0.92 (95% CI, 0.81-1.04) among Western-African-born, 0.87 (95% CI, 0.78-0.98) among Caribbean-born, and 0.53 (95% CI, 0.37-0.77) among Eastern-African-born black women. Patterns for hormone receptor-negative tumors were generally similar, although the differences between populations were attenuated. The test for heterogeneity by Census region was not significant in any of the comparisons (all P for heterogeneity >.05). CONCLUSIONS: The prevalence of triple-negative breast cancer among black women in the United States varied significantly by birthplace, particularly among Eastern-African-born black women. These findings underscore the importance of considering geographic origin in studies characterizing breast cancer among women of African descent in the United States and elsewhere.

In the United States, African American/black individuals bear a disproportionate share of the cancer burden, having the highest death rate and the lowest survival rate of any racial or ethnic group for most cancers. To monitor progress in reducing these inequalities, every 3 years the American Cancer Society provides the estimated number of new cancer cases and deaths for blacks in the United States and the most recent data on cancer incidence, mortality, survival, screening, and risk factors using data from the National Cancer Institute, the North American Association of Central Cancer Registries, and the National Center for Health Statistics. In 2019, approximately 202,260 new cases of cancer and 73,030 cancer deaths are expected to occur among blacks in the United States. During 2006 through 2015, the overall cancer incidence rate decreased faster in black men than in white men (2.4% vs 1.7% per year), largely due to the more rapid decline in lung cancer. In contrast, the overall cancer incidence rate was stable in black women (compared with a slight increase in white women), reflecting increasing rates for cancers of the breast, uterine corpus, and pancreas juxtaposed with declining trends for cancers of the lung and colorectum. Overall cancer death rates declined faster in blacks than whites among both males (2.6% vs 1.6% per year) and females (1.5% vs 1.3% per year), largely driven by greater declines for cancers of the lung, colorectum, and prostate. Consequently, the excess risk of overall cancer death in blacks compared with whites dropped from 47% in 1990 to 19% in 2016 in men and from 19% in 1990 to 13% in 2016 in women. Moreover, the black-white cancer disparity has been nearly eliminated in men <50 years and women ≥70 years. Twenty-five years of continuous declines in the cancer death rate among black individuals translates to more than 462,000 fewer cancer deaths. Continued progress in reducing disparities will require expanding access to high-quality prevention, early detection, and treatment for all Americans.

Survivorship statistics demonstrate that the incidence of cancer continues to rise worldwide, with a further 60% increase in diagnoses predicted by 2030 attributed to lifestyle risk factors, screening programmes resulting in earlier diagnosis but also the changing demographics of the population. More than a third of new cancer diagnoses and almost half of cancer survivors are now aged 70â¯years or older. Despite this increasing incidence, worldwide five-year cancer survival rates have improved significantly over the past two decades. After cancer, cardiovascular disease is the second most common cause of death in developed countries. With continued improvements in overall prognosis, patients with cancer have an increased exposure to cardiovascular risk factors resulting in higher cardiovascular morbidity and mortality, particularly in older patients. This relationship between cancer and cardiovascular disease is not surprising as they share the common risk factors of aging, smoking, obesity, and poor diet. In this review, we discuss the toxicity of cancer treatments on the cardiovascular system, particularly in older patients. We focus primarily on radiotherapy and anthracycline chemotherapy because of their chronic adverse effects and appraise approaches toward the detection and treatment of this toxicity to maximise survival and quality of life of older patients with cancer.

BACKGROUND & AIMS: There is limited information on contemporary incidence rates and trends, by race, ethnicity, and age, for major subtypes of esophageal and gastric cancer in the United States. We examined the most recent nationwide incidence data for esophageal squamous cell carcinoma, esophageal adenocarcinoma (EAC), gastric cardia adenocarcinoma (GCA), and gastric non-cardia adenocarcinoma (GNCA) by race, ethnicity, and age in the United States. METHODS: Average contemporary incidence rates (2010-2014) and annual percent changes in rates (from 1997 through 2014) by race, ethnicity, and age were calculated for each cancer subtype using nationwide data compiled by the North American Association of Central Cancer Registries. RESULTS: From 1997 through 2014, overall esophageal squamous cell carcinoma incidence rates continuously decreased in both sexes and all racial and ethnic groups, although rates remained stable among younger non-Hispanic white women. Overall, EAC incidence rates decreased or stabilized during the most recent time period (2006-2007 through 2014) in men and women, after increasing from 1997 through 2006 and 2007. However, EAC incidence rates continued to increase from 1997 through 2014 in several subpopulations, including non-Hispanic white men younger than 50 years, non-Hispanic white women younger than 70 years, and Asian/Pacific Islander men (all ages combined). Overall GCA incidence rates increased among non-Hispanic whites, but decreased among Hispanics (men only) and Asian/Pacific Islanders. Although overall GNCA rates decreased in both sexes and all racial and ethnic groups, rates increased in younger age groups among men (all races and ethnicities combined) and non-Hispanic white, non-Hispanic black, and Hispanic women. CONCLUSIONS: Using high-quality nationwide population-based data, we found increasing incidence trends for EAC, GCA, and GNCA in several subpopulations in the United States.
