ABSTRACT
Introducción y objetivo: Los tumores vesicales no musculo-invasivos presentan una elevada tasa de recurrencias y una baja tasa de progresión. El objetivo del estudio es evaluar la efectividad, seguridad y factibilidad de la fulguración con láser Holmium en régimen ambulatorio en tumores seleccionados. Material y método: Estudio prospectivo, longitudinal, de cohortes (enero de 2009 hasta diciembre de 2016). Se realizaron 79 procedimientos de fulguración con láser Holmium + instilación posterior de MMC en régimen ambulatorio en 59 pacientes con historia de neoplasia vesical de bajo riesgo y recidivas papilares de pequeño tamaño. Se realiza un análisis descriptivo de los datos y se analiza el tiempo libre de recidiva mediante curvas de Kaplan-Meier. Resultados: Todos los procedimientos se completaron en el día y sólo un paciente precisó ingreso posterior por hematuria. El 87.2% de los pacientes presentó dolor con EVA ≤ 3. Se objetivó recidiva tras el 49.4% de los procedimientos (27.3% a los 12 meses). La mediana de seguimiento fue de 17 meses (rango 2-65). La aparición de recidiva fue significativamente más precoz tras la segunda fulguración que tras la primera (mediana: 10 meses vs 56 meses). Conclusiones: La fulguración con láser Holmium + instilación posterior de MMC en régimen ambulatorio es una alternativa segura y factible a la RTUv en pacientes con tumores seleccionados. Probablemente sea recomendable realizar una RTUv en los pacientes con recidiva tras fulguración, dado que posiblemente el riesgo de progresión en estos pacientes es superior
Background and Objective: Nonmuscle invasive bladder cancer has a high recurrence rate and a low progression rate. The aim of this study was to assess the effectiveness, safety and feasibility of Holmium laser fulguration in an outpatient regimen for selected tumours. Material and Method: A prospective, longitudinal cohort study was conducted between January 2009 and December 2016. Seventy-nine Holmium laser fulguration procedures with subsequent instillation of mitomycin C were performed in an outpatient regimen on 59 patients with a history of low-risk bladder cancer and recurrence of small papillary tumours. We performed a descriptive data analysis and analysed the relapse-free time using Kaplan-Meier curves. Results: All procedures were completed in one day, and only one patient required subsequent hospitalisation due to haematuria. Some 87.2% of the patients presented pain with a visual analogue score ≤3. Recurrence occurred after 49.4% of the procedures (27.3% at 12 months). The median follow-up time was 17 months (range, 2-65). The onset of recurrence was significantly earlier after the second fulguration than after the first (median, 10 months vs. 56 months). Conclusions: Holmium laser fulguration and subsequent mitomycin C instillation in an outpatient regimen is a safe and feasible alternative to transurethral resection of bladder tumours in selected patients. Transurethral resection of the bladder tumour is recommended for patients with recurrence after fulguration, given the possibly higher risk of progression in these patients
