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.

[Association between diastolic stress test and H2FPEF score].

Objective: Heart failure with preserved ejection fraction is a highly prevalent disease; some advances for improving the diagnosis are the development of the H2FPEF score and the diastolic stress test for the evaluation of diastolic function. The objective is to describe the clinical and echocardiographic characteristics of patients referred for stress tests, and the association between the H2FPEF score and the results of the diastolic test.

Methods: This is an analytical, observational, retrospective study.

H NMR serum metabolomic profiling of patients at risk of cardiovascular diseases performing stress test.

Cardiovascular diseases are the leading cause of death worldwide. Changes in lifestyle and/or pharmacological treatment are able to reduce the burden of coronary artery diseases (CAD) and early diagnosis is crucial for the timely and optimal management of the disease. Stress testing is a good method to measure the burden of CAD but it is time consuming and pharmacological testing may not fully mimic exercise test.
