The Relationship of Race, Oncotype DX, and Ki67 in a Population Highly Screened For Breast Cancer.

Oncotype DX recurrence score (ODX) can predict risk of invasive breast cancer recurrence and benefit of chemotherapy. Literature is limited on the relationship of ODX and race in women with hormone receptor positive and node negative/positive disease. Our study examines the relationship between race and clinical characteristics within a population of highly screened women with newly diagnosed breast cancer. The institutional Breast Cancer Database was queried for patients with newly diagnosed breast cancer between January2010 and March2015. We analyzed clinical and tumor characteristics including ODX. Statistical analyses included Pearson's Chi-Square and Fisher's Exact Tests. There were 2,092 women in our study cohort. The majority had college-level education (84%), regular screening (78%), and clinical breast exams (88%). The majority had invasive ductal carcinoma (IDC) (62%), early stage (0, I, II) tumors (93%), ER+ (84%), PR+ (71%), Her2 negative (86%), and node negative disease (83%). There was a significantly higher proportion of later stage disease among African-Americans (p = 0.001) and Asians (p = 0.006) and more triple negative breast cancers among African-Americans (p < 0.0001). A majority of patients had a low ODX (56%). While ODX was not different among the race categories (p = 0.97), there were significant racial differences in Ki-67 (p < 0.0001). In a population of highly screened women, differences were found between races regarding tumor histology. No statistical difference between race and ODX was noted, but there were racial differences in Ki67. Therefore we recommend that further research be focused on refining management algorithms by ethnicity.

Demographic risk factors impacting timely radiation therapy completion after breast conserving surgery.

BACKGROUND: Radiotherapy completion (RTC) is critical to successful breast conserving treatment. Our aim was to identify patient groups at greatest risk of not achieving timely radiotherapy completion (TRTC) in an urban setting. METHODS: This observational cohort study used hospital registry data from 2004 to 2010 for female stage I and II breast conserving treatment patients to assess predictors of RTC and TRTC, defined as RTC of 35 to 49 days. RESULTS: Two hundred sixty-one patients were analyzed. There was no difference in mean days to RTC by ethnicity (black 46.8, white 46.4, Hispanic 48.1 days, P = .75) or total RTC (black 88.2%, white 97.9%, Hispanic 93.3%, P = .09). However, a substantial difference was seen in TRTC by ethnicity (black 51.8%, white 79.2%, Hispanic 57.8%, P = .03). Multivariate logistic regression analysis of failure to achieve TRTC found associations with black race (odds ratio [OR] 2.67), Medicare (OR 3.46), Medicaid (OR 2.19), and age less than 50 years (OR 4.13). CONCLUSIONS: This study demonstrates high overall percentage RTC but demonstrates disparities in TRTC. Those at greatest risk of unsuccessful TRTC were younger, Medicare or Medicaid insured, and black race.

The Maracaibo city metabolic syndrome prevalence study: design and scope.

The metabolic syndrome (MS) is a conglomerate of interrelated risk factors-including obesity, atherogenic dyslipidemia, arterial hypertension, and insulin resistance-which exponentially increase the risk of developing cardiovascular disease and type 2 diabetes mellitus. The purpose of this study was to determine the prevalence of MS according to the criteria published by the International Diabetes Federation, in individuals of both sexes over 18 years of age. This is a cross-sectional study based on MS prevalence in a representative sample from the Maracaibo district, Zulia State. The population of Maracaibo, according to the last census in 2001, was 1,219,927 habitants, with a 2007 population estimation of 1,428,043 habitants according to the National Institute of Statistics (NIS). Likewise, NIS projects that for the year 2009, 59.7% of the population of Venezuela will have individuals over 18 years of age. Using these data, the sample for Maracaibo District corresponds to 1986 individuals with or above 18 years of age. The data recollection was conducted by health professionals and medicine students, previously trained. The participants were subject to inquiry previous written consent and a medical examination, and qualitative variables such as smoking habit, socioeconomic status, physical activity, race, alcoholism, and nutritional habits, and quantitative ones like blood pressure, anthropometry, and blood works were determined. There is clear evidence that there is a lack of research and validated values to use as reference in our country and maybe in Latin America. Taking into account all that has been exposed here, this study will serve as a pilot for the numerous statistical determinations that will soon come afterward, providing first-hand accurate evidence on the behavior of the MS in the Latin American populace.

Epilepsy in The Alienist and Neurologist, 1880-1920.

PURPOSE: To study the history of epilepsy from 1880 to 1920. METHODS: We reviewed all 40 volumes of The Alienist and Neurologist and identified articles concerning primarily epilepsy. We analyzed three of these articles in greater detail. RESULTS: The Alienist and Neurologist published "Original Contributions,""Selections," (abstracts from other journals written by the editorial board), "Editorials," and (book) "Reviews." Of 258 epilepsy articles, there were 40 Original Contributions, 164 Selections, 39 Editorials, and 15 Reviews. These articles included 71 on therapy (41 medication, 13 surgery, and 17 other therapies); 66 general discussions; 46 on etiology or symptoms; 34 case studies; 28 social/legal articles; and 13 autopsy or pathology articles. CONCLUSIONS: Analysis of The Alienist and Neurologist provides a unique and valuable perspective on the clinical practice and academic world of epileptology during the decades around the turn of the twentieth century.
