Inferential Statistics from Black Hispanic Breast Cancer Survival Data

Abstract

In this paper we test the statistical probability models for breast cancer survival data for race and ethnicity. Data was collected from breast cancer patients diagnosed in United States during the years 1973–2009. We selected a stratified random sample of Black Hispanic female patients from the Surveillance Epidemiology and End Results (SEER) database to derive the statistical probability models. We used three common model building criteria which include Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), and Deviance Information Criteria (DIC) to measure the goodness of fit tests and it was found that Black Hispanic female patients survival data better fit the exponentiated exponential probability model. A novel Bayesian method was used to derive the posterior density function for the model parameters as well as to derive the predictive inference for future response. We specifically focused on Black Hispanic race. Markov Chain Monte Carlo (MCMC) method was used for obtaining the summary results of posterior parameters. Additionally, we reported predictive intervals for future survival times. These findings would be of great significance in treatment planning and healthcare resource allocation.

Differences in breast cancer outcomes amongst Black US-born and Caribbean-born immigrants

“…There is conflicting data on Hispanic women's risk of breast cancer specific-mortality compared to NHW women. The scarce data available show worse outcomes to Hispanic Whites (HW) but lower or similar risk of breast cancer mortality to NHB, however, the reasons behind these findings have not yet been explored [26][27][28][29]. The majority of the Hispanic Black women in our cohort were born in Cuba and Dominican Republic.…”

Black Hispanic and Black Non-Hispanic Breast Cancer Survival Data Analysis with Half-normal Model Application

“…BNH women have a lower survival rate than other racial and ethnic groups in the United States and also have a low chance of recovery due to more aggressive tumors associated with late stage diagnosis (Siegel at al., 2012b(Siegel at al., , 2012aACS, 2013a). BNH women had a 1.5-2.5 increased risk of having stage IV breast cancer and are more likely to die of a cancer specific death compared to white nonHispanic women (Banegas and Li, 2012;Khan et al, 2014e).…”

“…Few research studies exist on cancer related health disparities among Hispanic women of different races (Black and White) (Banegas and Li, 2012;Khan et al, 2014). Hispanic women, of all races, are also more likely to die from breast cancer in comparison to white non-Hispanic women, even when diagnosed at the same stage and age (ACS, 2013a;Siegel at al., 2012b).…”
