5hmC-profiles in Puerto Rican Hispanic/Latino men with aggressive prostate cancer.

Puerto Rican (PR) Hispanic/Latino (H/L) men are an understudied population that has the highest prostate cancer (PCa) specific mortality among other Hispanic populations. Little information is known about the higher mortality in PR H/L men. It is thought that epigenetic changes in key genes may play a critical role in aggressive tumors.

Epigenome-wide association study of prostate cancer in African American men identified differentially methylated genes.

Introduction: Men with African ancestry have the highest incidence and mortality rates of prostate cancer (PCa) worldwide.

Methods: This study aimed to identify differentially methylated genes between tumor vs. adjacent normal and aggressive vs.

Spectrum of somatic mutational features of colorectal tumors in ancestrally diverse populations.

Unlabelled: Ancestrally diverse and admixed populations, including the Hispanic/Latino/a/x/e community, are underrepresented in cancer genetic and genomic studies. Leveraging the Latino Colorectal Cancer Consortium, we analyzed whole exome sequencing data on tumor/normal pairs from 718 individuals with colorectal cancer (128 Latino, 469 non-Latino) to map somatic mutational features by ethnicity and genetic ancestry. Global proportions of African, East Asian, European, and Native American ancestries were estimated using ADMIXTURE.

Piloting a Spanish-Language Web-Based Tool for Hereditary Cancer Genetic Testing.

The delivery of hereditary cancer pre-test education among Spanish-language patients is impeded by the dearth of Spanish-speaking genetic counselors. To address this gap, we evaluated a web-based genetic education tool delivered in Spanish to provide information typically discussed during an initial genetic counseling session. Spanish-speaking patients with a personal or family history of cancer were recruited at two centers in Puerto Rico and through social media.
