Concordance between 21-gene recurrence score assay and clinicopathological predictive models in early-breast cancer patients cared for at a cancer center in Colombia.

Introduction: The genomic-based 21-gene recurrence score assay (21-GRSA) allows to determine the usefulness of adjuvant chemotherapy in patients with luminal-type early breast cancer (LTEBC). Additional predictive models have also been developed, such as Magee equations (ME), the Predict model (PM), and the Tennessee nomogram score (TNS).

Objective: To evaluate the concordance between 21-GRSA, ME, PM and TNS.

Real-world evidence of nivolumab for non-small-cell lung cancer in a developing country.

Nivolumab is a human programmed death receptor-1 blocking antibody, used as treatment option in patients with advanced non-small-cell lung cancer (NSCLC). We assessed the nivolumab efficacy in terms of survival and response to treatment as second-line (2L) or third-line (3L) therapy in patients with advanced NSCLC. This is a multicentric observational study.

Emergency Embolization of Pelvic Vessels in Patients With Locally Advanced Cervical Cancer and Massive Vaginal Bleeding: A Case Series in a Latin American Oncological Center.

Purpose: Locally advanced cervical cancer may present with uncontrollable vaginal bleeding in up to 70% of cases. Pelvic vessel embolization has been used as an urgent maneuver for achieving fast hemostatic control. This report describes outcomes of selective pelvic vessel embolization in patients with severe bleeding due to a locally advanced cervical cancer.

Epidemiology and genetic diversity of circulating dengue viruses in Medellin, Colombia: a fever surveillance study.

Background: Dengue fever is a major public health problem in Colombia. A fever surveillance study was conducted for evaluation of the clinical, epidemiological, and molecular patterns of dengue, prior to Chikungunya and Zika epidemics.

Methods: In November 2011-February 2014, a passive facility-based surveillance was implemented in Santa Cruz Hospital, Medellin, and enrolled eligible febrile patients between 1 and 65 years-of-age.

Dengue virus serological prevalence and seroconversion rates in children and adults in Medellin, Colombia: implications for vaccine introduction.

Background: Dengue is an important public health problem worldwide. A vaccine has recently been licensed in some countries of Latin America and Asia. Recommendations for dengue vaccine introduction include endemicity and a high serological prevalence of dengue in the territories considering its introduction.
