Ovarian Cancers

ObjectiveOvarian cancer in Black women is common in many West African countries but is relatively rare in North America. Black women have worse survival outcomes when compared to White women. Ovarian cancer histotype, diagnosis, and age at presentation are known prognostic factors for outcome. We sought to conduct a preliminary comparative assessment of these factors across the African diaspora.MethodsPatients diagnosed with ovarian cancer (all histologies) between June 2016-December 2019 in Departments of Pathology at 25 participating sites in Nigeria were identified. Comparative population-based data, inclusive of Caribbean-born Blacks (CBB) and US-born Blacks (USB), were additionally captured from the International Agency for Research on Cancer and Florida Cancer Data Systems. Histology, country of birth, and age at diagnosis data were collected and evaluated across the three subgroups: USB, CBB and Nigerians. Statistical analyses were done using chi-square and student’s t-test with significance set at p<0.05.ResultsNigerians had the highest proportion of germ cell tumor (GCT, 11.5%) and sex-cord stromal (SCST, 16.2%) ovarian cancers relative to CBB and USB (p=0.001). CBB (79.4%) and USB (77.3%) women were diagnosed with a larger proportion of serous ovarian cancer than Nigerians (60.4%) (p<0.0001). Nigerians were diagnosed with epithelial ovarian cancers at the youngest age (51.7± 12.8 years) relative to USB (58.9 ± 15.0) and CBB (59.0± 13.0,p<0.001). Black women [CBB (25.2 ± 15.0), Nigerians (29.5 ± 15.1), and USB (33.9 ± 17.9)] were diagnosed with GCT younger than White women (35.4 ± 20.5, p=0.011). Black women [Nigerians (47.5 ± 15.9), USB (50.9 ± 18.3) and CBB (50.9 ± 18.3)] were also diagnosed with SCST younger than White women (55.6 ± 16.5, p<0.01).ConclusionThere is significant variation in age of diagnosis and distribution of ovarian cancer histotype/diagnosis across the African diaspora. The etiology of these findings requires further investigation.

Background: Self-poisoning (overdose) is the commonest form of self-harm cases presenting to acute secondary care services in the UK, where there has been limited investigation of self-harm in black and minority ethnic communities. London has the UK’s most ethnically diverse areas but presents challenges in resident-based data collection due to the large number of hospitals. Aims: To investigate the rates and characteristics of self-poisoning presentations in two central London boroughs. Method: All incident cases of self-poisoning presentations of residents of Lambeth and Southwark were identified over a 12-month period through comprehensive acute and mental health trust data collection systems at multiple hospitals. Analysis was done using STATA 12.1. Results: A rate of 121.4/100,000 was recorded across a population of more than half a million residents. Women exceeded men in all measured ethnic groups. Black women presented 1.5 times more than white women. Gender ratios within ethnicities were marked. Among those aged younger than 24 years, black women were almost 7 times more likely to present than black men were. Conclusion: Self-poisoning is the commonest form of self-harm presentation to UK hospitals but population-based rates are rare. These results have implications for formulating and managing risk in clinical services for both minority ethnic women and men.

AbstractBackgroundSex- and race-specific pooled cohort equations (PCE) are recommended for estimating the 10-year risk of cardiovascular disease (CVD), with an absolute risk >7.5% indicating a clinical decision threshold.MethodsWe generated in silico 30,565 risk profiles in men and 29,515 in women by combining numerical (age, total and high-density lipoprotein cholesterol, systolic blood pressure) and binary risk factors (smoking, diabetes, antihypertensive treatment). We compared PCE-estimated 10-year CVD risk in Black versus white individuals with identical risk profiles. We performed similar comparisons in participants in the Framingham Third Generation cohort and the National Health and Nutrition Examination Survey 2017-2018.ResultsThere were 6357 risk profiles associated with 10-year CVD risk >7.5% for Black but not for white men (median risk difference [RD] 6.25%, range 0.15-22.8%; median relative risk [RR] 2.40, range 1.02-12.6). There were 391 profiles with 10-year CVD risk >7.5% for white but not for Black men (median RD 2.68%, range 0.07-16.9%; median RR 1.42, range 1.01-3.57). There were 6543 risk profiles associated with 10-year estimated CVD risk >7.5% for Black but not for white women (median RD 6.14%, range 0.35-26.8%; median RR 2.29, range 1.05-12.6). There were 318 profiles with 10-year CVD risk >7.5% for white but not for Black women (median RD 3.71%, range 0.22-20.1%; median RR 1.66, range 1.03-5.46). The population-based samples demonstrated similar risk differences.ConclusionsThe PCE may generate substantially divergent CVD risk estimates for Black versus white individuals with identical risk profiles, which could introduce race-related variations in clinical recommendations for CVD prevention.

Long Term Survivors

Breast cancer is one of the most common diseases among women worldwide with about 25% of new cases each year. In Brazil, 59,700 new cases of breast cancer were expected in 2019, according to the Brazilian National Cancer Institute (INCA). Survival analysis has been an useful tool for the identifying the risk and prognostic factors for cancer patients. This work aims to characterize the prognostic value of demographic, clinical and pathological variables in relation to the survival time of 2,092 patients diagnosed with breast cancer in Parana State, Brazil, from 2004 to 2016. In this sense, we propose a Bayesian analysis of survival data with long-term survivors by using Weibull regression models through integrated nested Laplace approximations (INLA). The results point to a proportion of long-term survivors around 57:6% in the population under study. In regard to potential risk factors, we namely concluded that 40-50 year age group has superior survival than younger and older age groups, white women have higher breast cancer risk than other races, and marital status decreases that risk. Caution on the general use of these results is nevertheless advised, since we have analyzed population-based breast cancer data without proper monitoring by a healthprofessional.

0022 Inflammatory cytokines enhance the spontaneous beating rate of cardiac myocytes. We hypothesize that higher levels of interleukin-6 (IL-6) may be associated with a higher resting heart rate in a population-based sample. IL-6 (mean±SEM 2.39±0.5 ng/ml, range 0.21-15.96 ng/ml, n=2824) was measured in Health ABC, a cohort study of 3075 well functioning older adults living in Memphis, TN, and Pittsburgh, PA (age 73.6±0.3 years, 51.5% women, 41.7% African American). Heart rate was calculated from electrocardiogram strips recorded at the baseline clinic visit after 15 min resting in supine position. Participants with arrhythmias or conduction anomalies were excluded. After adjustment for demographics, body-mass index, smoking, history of cardiovascular disease, and use of digoxin, beta-blockers, calcium antagonists, anti-inflammatory drugs and antiarrhythmic drugs, higher log (IL-6) was significantly correlated with a higher heart rate (β=.17, p<0.001, n=2377). Such an association was significant in all race and gender strata (white men β=0.17, p<0.001; white women β=0.13, p=0.001; black men β=0.18, p<0.001; black women β=0.18, p<0.001). The overall il-6/heart rate association was even more evident when the analyses were restricted to the participants who had no history of cardiovascular disease and were not using any these cardiovascular drugs (β=0.21, p<0.001, n=1196). The table shows heart rate according to IL-6 quintiles. Circulating IL-6 was strongly and independently correlated with resting heart rate. Circulating IL-6 is a possible biological mediator that may contribute to explain the increased mortality associated with high heart rate. Table 1.

Race Disparities

Abstract Background In Brazil, inequalities in access may interfere with cancer care. This study aimed to evaluate the influence of race on breast cancer mortality in the state of São Paulo, from 2000 to 2017, contextualizing with other causes of death. Methods A population-based retrospective study using mortality rates, age and race as variables. Information on deaths was collected from the Ministry of Health Information System. Only white and black categories were used. Mortality rates were age-adjusted by the standard method. For statistical analysis, linear regression was carried out. Results There were 60,940 deaths registered as breast cancer deaths, 46,365 in white and 10,588 in black women. The mortality rates for 100,000 women in 2017 were 16.46 in white and 9.57 in black women, a trend to reduction in white (p = 0.002), and to increase in black women (p = 0.010). This effect was more significant for white women (p < 0.001). The trend to reduction was consistent in all age groups in white women, and the trend to increase was observed only in the 40–49 years group in black women. For ‘all-cancer causes’, the trend was to a reduction in white (p = 0.031) and to increase in black women (p < 0.001). For ‘ill-defined causes’ and ‘external causes’, the trend was to reduce both races (p < 0.001). Conclusion The declared race influenced mortality rates due to breast cancer in São Paulo. The divergences observed between white and black women also were evident in all cancer causes of death, which may indicate inequities in access to highly complex health care in our setting.

Racial Inequalities

The aim of this population-based cross-sectional study was to investigate access by 20 to 60 year-old women - both black and white - to early detection (pap-smear) exams for breast and cervical cancer in two towns - São Leopoldo and Pelotas - in Rio Grande do Sul State, southern Brazil. Estimates of the association between race/color and access to pap-smear and breast exams were adjusted for income, education, economic class and age. Of the 2,030 women interviewed, 16.1% were black and 83.9%, white. Black women were significantly less likely to have had a pap-smear and/or breast exam than white women. Racial inequalities in access to cancer early detection exams persisted after controlling for age and other socioeconomic factors. Racial differentials in access to early detection (pap-smear) exams for breast and cervical cancers might result from racial and socioeconomic inequalities experienced by black women in access to reproductive health care services and programs.

We estimated changes in the prevalence of chronic hypertension among pregnant women and evaluated the extent to which changes in obesity and smoking were associated with these trends. We designed a population-based cross-sectional analysis of over 151 million women with delivery-related hospitalizations in the United States, 1970 to 2010. Maternal age, year of delivery (period), and maternal year of birth (birth cohort), as well as race, were examined as risk factors for chronic hypertension. Prevalence rates and rate ratios with 95% CIs of chronic hypertension in relation to age, period, and birth cohort were derived through age-period-cohort models. We also examined how changes in obesity and smoking rates influenced age-period-cohort effects. The overall prevalence of chronic hypertension was 0.63%, with black women (1.24%) having more than a 2-fold higher rate than white women (0.53%; rate ratio, 2.31; 95% CI, 2.30–2.32). In the age-period-cohort analysis, the rate of chronic hypertension increased sharply with advancing age and period from 0.11% in 1970 to 1.52% in 2010 (rate ratio, 13.41; 95% CI, 13.22–13.61). The rate of hypertension increased, on average, by 6% (95% CI, 5–6) per year, with the increase being slightly higher among white (7%; 95% CI, 6%–7%) than black (4%; 95% CI, 3%–4%) women. Adjustments for changes in rates of obesity and smoking were not associated with age and period effects. We observed a substantial increase in chronic hypertension rates by age and period and an over 2-fold race disparity in chronic hypertension rates.

Never Smokers

This observational epidemiological study investigates sex/gender and racial differences in prevalence of COPD among never-smokers. Data were derived from the 2012 Center for Disease Control’s Behavioral Risk Factor Surveillance System. The sample consisted of 129,535 non-Hispanic whites and blacks 50 years of age and older who had never smoked. Descriptive and multivariable analyses were conducted, with the latter using a series of logistic regression models predicting COPD status by sex/gender and race, adjusting for age, height, socioeconomic position (SEP), number of household members, marital status, and health insurance coverage. Black women have the highest prevalence of COPD (7.0%), followed by white women (5.2%), white men (2.9%), and black men (2.4%). Women have significantly higher odds of COPD than men. When adjusting for SEP, black and white women have comparably higher odds of COPD than white men (black women OR = 1.66; 99% CI = 1.46, 1.88; white women OR = 1.49; 99% CI = 1.37, 1.63), while black men have significantly lower odds (OR = 0.62; 99% CI = 0.49, 0.79). This research provides evidence that racial inequalities in COPD (or lack thereof) may be related to SEP.
