Abstract
Los resultados de pacientes con cáncer colorrectal metastásico (CCRm) han mejorado gracias a la identificación de biomarcadores con utilidad pronóstica y predictiva. El presente análisis retrospectivo fue llevado a cabo para evaluar la utilidad de biomarcadores clave y parámetros clínicos en predecir los resultados de pacientes españoles con CCRm. Material y métodos: Se han analizado de manera retrospectiva muestras tumorales de una serie de pacientes mayores de 18 años con CCRm que fueron tratados en el Hospital General Universitario Gregorio Marañón (España). La reacción en cadena de la polimerasa en tiempo real fue empleada para detectar mutaciones en KRAS, NRAS, BRAF y PI3K. El resultado de mayor interés fue la supervivencia global. Las curvas de supervivencia, estimadas por el método de Kaplan-Meier, se han estratificado en base a las variables de mayor relevancia clínica. Las diferencias se han testado usando el test de log-rank...
Outcomes for patients with metastatic colorectal cancer (mCRC) have been improved by the identification of biomarkers predictive and prognostic of clinical outcome. The present retrospective analysis was undertaken to assess the utility of key biomarkers and clinical parameters in predicting outcomes in Spanish patients with mCRC. Methods: We retrospectively analyzed tumor samples from a series of patients aged >18 years withm CRC who were treated at the Hospital General Universitario Gregorio Marañón (Spain). Real-time polymerase chain reaction was used to detect KRAS, NRAS, BRAF, and PIK3CA mutations. The key outcome of interest was overall survival (OS). Survival curves were estimated using the Kaplan–Meier method and stratified by the variables of greatest clinical interest. Differences were tested using the log-rank test...
