Abstract
El cáncer de vejiga es el décimo tumor más frecuente en el mundo, con el 75% de los pacientes presentando enfermedad no músculo invasiva al diagnóstico. El cáncer de vejiga no músculo invasivo (CVNMI) de alto riesgo se trata habitualmente con resección transuretral e instilaciones intravesicales de BCG, un bacilo vivo atenuado que se ha utilizado para esta indicación desde hace décadas. Las tasas de recurrencia y progresión con este tratamiento son elevadas y es necesario buscar nuevas alternativas terapéuticas. A pesar de su relativamente elevada frecuencia, y que el tratamiento estándar es la inmunoterapia, el microambiente tumoral ha sido poco estudiado, especialmente en etapas tempranas de la enfermedad...
Bladder cancer is the tenth most common tumour worldwide, with 75% of patients presenting with non-muscle invasive disease at diagnosis. High-risk non-muscle invasive bladder cancer (NMIBC) is usually treated with transurethral resection and intravesical instillations of BCG, a live attenuated bacillus that has been used for this indication for decades. Recurrence and progression rates with this treatment are high, and new therapeutic alternatives need to be explored. Despite its relatively high frequency and the fact that the standard treatment is immunotherapy, the tumour microenvironment has been poorly studied, especially in the early stages of the disease...
