Abstract
El cáncer de mama (CM) es una enfermedad que se clasifica en distintos subtipos según la presencia de receptores hormonales (RH), principalmente estrógenos (RE), y la positividad del receptor 2 del factor de crecimiento epidérmico humano (HER2). El subtipo más frecuente es el CM luminal RH+ HER2-.Aunque en la mayoría de los casos se diagnostica en una etapa localizada, lo que permite un enfoque curativo, algunos pacientes desarrollan metástasis con el tiempo. En otros casos, la enfermedad se detecta directamente en fase metastásica. En este contexto, han surgido fármacos inhibidores de ciclinas 4/6 (iCDK4/6), como palbociclib o ribociclib, que han cambiado el paradigma de tratamiento de esta patología. Es interesante conocer la efectividad de estos fármacos en un entorno ajeno al de los ensayos clínicos, que permita analizar la influencia de las diferentes características basales tanto en la SLP como en la SG de las pacientes con CMM RH+HER2...
Breast cancer (BC) is a disease classified into distinct subtypes based on the presence of hormone receptors (HR), primarily estrogen receptors (ER), and the positivity of human epidermal growth factor receptor 2 (HER2). The most common subtype is luminal HR+ HER2- BC. Although most cases are diagnosed at a localized stage, allowing for a curative approach, some patients develop metastases over time. In other cases, the disease is directly detected at the metastatic stage.In this context, cyclin-dependent kinase 4/6 inhibitors (CDK4/6i), such as palbociclib and ribociclib, have emerged, revolutionizing the treatment paradigm for this condition. Itis of interest to evaluate the effectiveness of these drugs in real-world settings, outside clinical trials, to analyze the influence of baseline characteristics on progression-free survival (PFS) and overall survival (OS) in patients with HR+ HER2- metastatic breast cancer (MBC).In addition to...
