E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the rate of recurrence and/or progression and time free until first event in patients with non-muscle-invasive bladder tumor receiving mitomycin C with EMDA (MMC+EMDA) prior to transurethral resection of the bladder (TUR-B) compared with instillation of MMC by passive diffusion after TUR-B. |
Evaluar la tasa de recidiva y/o progresión y el tiempo libre hasta el primer evento en los pacientes con tumor vesical no músculoinvasivo que reciben mitomicina C con EMDA (MMC+EMDA) antes de la resección transuretral vesical (RTU) en comparación con la instilación de MMC por difusión pasiva tras la RTU. |
|
E.2.2 | Secondary objectives of the trial |
− To analyze the rate of progression and progression-free-survival time in patients with electromotive drug administration (EMDA) before transurethral resection of the bladder (TUR-B) compared with passive diffusion of mitomycin C (MMC) instillation after TUR. − Evaluate the tolerance of treatment with preoperative MMC+EMDA. − Quantify the percentage of patients in each group who complete with the entire treatment. − To assess the impact of inflammatory markers (neutrophil/lymphocyte ratio and platelet/lymphocyte ratio) on the risk of recurrence and progression of non-muscle-invasive urothelial carcinoma. |
− Analizar la tasa de progresión y el tiempo libre hasta progresión en los pacientes con EMDA antes de la RTU en comparación con la instilación de MMC por difusión pasiva tras la RTU. − Evaluar la tolerancia del tratamiento con MMC+EMDA preoperatoria. − Cuantificar el porcentaje de pacientes en cada grupos que cumplen la totalidad del tratamiento. − Evaluar el impacto de los marcadores inflamatorios (ratio neutrófilo/linfocito y ratio plaqueta/linfocito) en el riesgo de recurrencia y de progresión del carcinoma urotelial no musculoinfiltrante. |

E.5 End points |
E.5.1 | Primary end point(s) |
Intravesical administration of EMDA-Mitomycin C pre-TURB is superior to standard intravesical administration of mitomycin C, by passive diffusion post-TURB, in terms of recurrence and progression rates. |
La administración intravesical de EMDA-Mitomicina C pre-RTU es superior a la administración intravesical estándar de mitomicina C, por difusión pasiva post-RTU, en términos de tasas de recidiva y progresión. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
An interim statistical analysis will be performed approximately 36 months after the start of the study with all the recruited patients. Subsequently, after completing the data collection and completing the 36-month follow-up of the sample, the definitive statistical analysis will be carried out and later the writing of the scientific work will begin. |
Se realizará un análisis estadístico intermedio aproximadamente a los 36 meses del inicio del estudio con la totalidad de los pacientes reclutados. Posteriormente, tras finalizar con la recogida de los datos y cumplimentado el seguimiento de 36 meses de la muestra, se realizará el análisis estadístico definitivo y posteriormente se iniciará la redacción del trabajo científico. |
|
E.5.2 | Secondary end point(s) |
Intravesical administration of EMDA-Mitomycin C pre-TURB is well tolerated by patients, and a very high percentage can finish the treatment. |
La administración de mitomicina C con EMDA de forma preoperatoria es bien tolerada por los pacientes, y se consigue un porcentaje de pacientes muy elevado que pueden finalizar con el tratamiento. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The rate of patients successfully completing treatment will be assessed. as well as the side effects that may arise during it periodically, issuing definitive results at the end of the follow-up of all patients. |
Se evaluará la tasa de pacientes que finalizan correctamente el tratamiento. así como los efectos secundarios que puedan surgir durante el mismo de forma periódica, emitiendo resultados definitivos al acabar el seguimiento de todos los pacientes. |
