Germline Pathogenic Variant Prevalence Among Latin American and US Hispanic Individuals Undergoing Testing for Hereditary Breast and Ovarian Cancer: A Cross-Sectional Study.

Purpose: To report on pathogenic germline variants detected among individuals undergoing genetic testing for hereditary breast and/or ovarian cancer (HBOC) from Latin America and compare them with self-reported Hispanic individuals from the United States.

Methods: In this cross-sectional study, unrelated individuals with a personal/family history suggestive of HBOC who received clinician-ordered germline multigene sequencing were grouped according to the location of the ordering physician: group A, Mexico, Central America, and the Caribbean; group B, South America; and group C, United States with individuals who self-reported Hispanic ethnicity. Relatives who underwent cascade testing were analyzed separately.

Breast Implant-associated Anaplastic Large Cell Lymphoma in Colombia: Report of a Multidisciplinary National Registry.

Unlabelled: An estimated 43,390 breast augmentation surgeries (86,780 implants) and 1486 breast implant reconstructions are performed annually in Colombia, representing the second-most breast surgery destination in South America, the fourth in the western hemisphere, and the fifth country worldwide. No previous reports have evaluated the incidence of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) epidemiology or outcomes in a Hispanic population. Published data on the incidence of this disease in Colombia are unknown; therefore, a National Joint Multidisciplinary Committee was developed between the Colombian scientific societies of Mastology, Plastic Surgery, Hemato-Oncology, and the Invima (The National Food and Drug Surveillance Institute) to track national cases of BIA-ALCL.

[Association between delayed diagnosis and breast cancer in advanced clinical stage at the time of consultation in four oncology centers in Medellin- Colombia, 2017. Cross-sectional study].

Objective: To determine the association between delayed diagnosis and advanced clinical stage breast cancer, and to explore the factors that influence this delay.

Methods: Cross-sectional study of women over 18 years of age with breast cancer who attended 4 oncology centers in Medellín, Colombia, in 2017. The "Breast Cancer Delay Questionnaire" which includes sociodemographic and clinical variables as well as time intervals was used.

[Survival difference due to types of health coverage in breast cancer patients treated at a specialized cancer center in Medellín, Colombia].

The study aimed to estimate the effect of health insurance on overall survival and disease-free survival in breast cancer patients undergoing surgery at the Las Américas Oncology Institute in Medellín, Colombia, with data from the institutional registry. The variables were compared between subsidized coverage and contributive coverage with chi-squared test (χ2) or Student t test, Kaplan-Meier, and log-rank test. The target variable was adjusted with Cox regression.
