Epstein-Barr virus in gastric cancer and association with 30 bp del-latent membrane protein 1 polymorphism.
This study aimed to determine the frequencies of Epstein-Barr virus, types 1 and 2 infection, and 30 bp del-latent membrane protein 1 viral polymorphism in gastric adenocarcinomas, as well as to investigate the association between Epstein-Barr virus infection and tumor location, type, and the patient's sex. ⋯ Epstein-Barr virus infection was found in 68.4% of tumors investigated in this study. To the best of our knowledge, this is the first article showing the coinfection of Epstein-Barr virus types 1 and 2 in gastric carcinoma in Brazil.

Observational StudyAncestry and self-reported race in Brazilian breast cancer women.
This study aimed to evaluate the association between self-reported race/color and ancestry in Brazilian patients with breast cancer. ⋯ Although we found many similarities between white European ancestry, black African ancestry, and yellow Asian ancestry, there is great miscegenation between patients. Although they can be labeled as having one race, they do present many ancestral genes that would allow their inclusion in another race group.
