Is trimodal therapy the current standard for muscle-invasive bladder cancer?

OBJECTIVE: The aim of this review is to summarize the current evidence and future perspectives of bladder-sparing treatment for MIBC. METHODS: A non-systematic literature search in Medline/Pubmed was performed in October 2023 with the following keywords "bladder cancer", "bladder-sparing", "trimodal therapy", "chemoradiation", "biomarkers", "immunotherapy", "neoadjuvant chemotherapy", "radiotherapy". RESULTS: Urology guidelines recommend radical cystectomy as the standard curative treatment for muscle-invasive urothelial bladder cancer, reserving radiotherapy for patients who are unfit or who want to preserve their bladder. Given the morbidity and mortality of cystectomy and its impact on quality of life and bladder function, modern oncologic therapies are increasingly oriented toward organ preservation and maximizing functional outcomes while maintaining treatment efficacy. Trimodal therapy, which incorporates maximal transurethral resection followed by radiotherapy with concurrent radiosensitizing chemotherapy, is an effective regimen for bladder function preservation in well-selected patients. Despite the absence of comparative data from randomized trials, the two approaches seem to provide comparable oncologic outcomes. Studies are evaluating the expansion of eligibility criteria for trimodal therapy, the optimization of radiotherapy and immunotherapy delivery to further improve outcomes, and the validation of biomarkers to guide bladder preservation. CONCLUSIONS: Trimodal therapy has shown acceptable outcomes for bladder preservation; therefore, it provides a valid treatment option in well-selected patients.

Evaluation of the Spanish Urological Association quality care indicators in a kidney transplantation programme. / Evaluación de los indicadores de calidad asistencial de la Asociación Española de Urología en un programa de trasplante renal.

INTRODUCTION: Indicators show the presence of a phenomenon and its intensity. They assess the level of quality care and identify potential situations for improvement. Our objective is to assess the 2013 and 2014 quality care indicators of our department's kidney transplantation area. MATERIAL AND METHOD: For 2013 and 2014, we reviewed 88 and 106 kidney transplants and 47 and 66 extractions. We evaluated the quality care indicators developed by the Spanish Urological Association, analysing the results with the SPSS v 21.0 programme. RESULTS: The mean cold ischaemia time (CIT) was 14.96hours in 2013 and 18.07hours in 2014. The CIT was ≤18h in 53% and 56% of cadaveric donor kidneys in 2013 and 2014, respectively. The rate of relevant early onset urinary fistulae was 1.14% and 2.83% for each year. The rate of early transplantectomy due to a vascular complication was 3.41% and 2.83% for 2013 and 2014, respectively. Overall patient survival at 1 year was 100% for both periods, and graft survival at 1 year was 95% and 94.34% for 2013 and 2014, respectively. The rate of living-donor transplantation was 14.77% and 17.92%, and 92.31% and 68.42% of the living-donor extractions were laparoscopic for 2013 and 2014, respectively. Resident medical interns were the first surgeon in 6.67% and 12.64% of the transplantations and in 55.88% and 19.14% of the cadaveric extractions during 2013 and 2014, respectively. CONCLUSIONS: During the evaluated period, all quality care standards in kidney transplantation were met, except for CIT in both years and resident medical intern participation in kidney implantation in 2013. This analysis promotes improvements in quality care, highlighting weak spots that need work.

Tratamiento conservador del carcinoma renal de novo sobre injerto renal / Conservative treatment of de novo renal carcinoma on kidney graft

Introducción: El carcinoma renal de novo en el trasplante renal es una situación poco frecuente pero no excepcional, de mucha trascendencia por la potencial mortalidad del receptor o pérdida del injerto. El objetivo de nuestro trabajo es conocer el manejo y evolución de estos tumores en nuestra unidad de trasplante renal. Material y métodos: Analizamos los casos de tumor renal de novo entre los trasplantados de los últimos 17 años en nuestra unidad de trasplante renal, detectando 3 casos de carcinoma de células claras y uno de carcinoma papilar sobre el injerto. Se realizó seguimiento desde el punto de vista oncológico y de función renal, y se analizó la respuesta a cambios en la inmunosupresión. Resultados: En todos los casos se practicó tumorectomía, precisándose en el paciente con carcinoma papilar trasplantectomía posteriormente. En ningún caso hubo complicaciones quirúrgicas relevantes. Además, se realizó conversión a un inhibidor de señales de proliferación o inhibidor de la mTOR y retirada completa de anticalcineurínicos. Con un seguimiento medio de 43,5 meses (15-61) los 3 pacientes con carcinoma de células claras sobreviven con buena función del injerto y sin datos de recidiva tumoral. El paciente con carcinoma papilar realiza seguimiento en otro centro hospitalario. Conclusiones: La cirugía conservadora, junto con la conversión a un inhibidor de señales de proliferación, parecen ser una opción segura para el tratamiento de tumores primarios en injerto renal, ofreciendo buenos resultados oncológicos y en cuanto a función renal a corto y medio plazo

Background: De novo renal carcinoma in kidney transplants is an uncommon but not exceptional condition and is of significant importance due to the potential for recipient mortality and graft loss. The aim of our study was to determine the management and outcome of these tumors in our Kidney Transplantation Unit. Material and methods: We analyzed cases of de novo kidney tumors among patients who underwent transplantation in the last 17 years in our Kidney Transplantation Unit. We detected 3 cases of clear cell carcinoma and 1 case of papillary carcinoma on the graft. We conducted follow-up on the tumor and renal function and analyzed patient responses to changes in immunosuppression. Results: Tumorectomy was performed in all cases, and subsequent transplantectomy was required for patients with papillary carcinoma. None of the patients had relevant surgical complications. We also changed the patients’ regimen to a proliferation signal inhibitor or mTOR inhibitor and completely withdrew all anticalcineurin agents. With a mean follow-up of 43.5 months (15-61), the 3 patients with clear cell carcinoma survived with good graft function and with no evidence of tumor recurrence. The patient with papillary carcinoma underwent follow-up at another hospital center. Conclusions: Conservative surgery along with conversion to a proliferation signal inhibitor appears to be a safe option for treating primary tumors in kidney grafts and offers good oncological and renal function results in the short and medium term
