Carcinoma urotelial sarcomatoide de vejiga en el adulto: histología, sintomatología, tratamientos y supervivencia / Sarcomatoid urothelial bladder carcinoma in adults: Histology, symptomatology, treatments and survival

Objetivo: El carcinoma urotelial sarcomatoide vesical representa el 0,3% de los tumores de vejiga y es considerado unos de los tumores más agresivos del tracto urinario. Nuestro objetivo es analizar las características del carcinoma urotelial sarcomatoide de vejiga en la edad adulta, tratamientos realizados y supervivencia. Método: Estudio retrospectivo entre el año 2000 y el 2017 de todos los pacientes con diagnóstico de carcinoma urotelial sarcomatoide de vejiga en un solo centro. Se analizan características anatomopatológicas, sintomatología en el momento del diagnóstico, tratamiento realizado y supervivencia según tratamiento llevado a cabo. Resultados: Dieciséis pacientes fueron diagnosticados de carcinoma sarcomatoide, 11 sin componente heterólogo, uno con componente rabdomiosarcoma, 2 con componente condrosarcoma y 2 con componente osteosarcoma. La edad media fue de 74 años (± 20) y el 88% eran fumadores. El síntoma principal fue la hematuria y el peor tolerado la disuria conjuntamente con el dolor hipogástrico. El 94% de los pacientes presentaron infiltración de la capa muscular y el 18% metástasis en el momento del diagnóstico. En el 37% de los pacientes se realizó tratamiento mediante cistectomía radical, en el 13% mediante cistectomía radical más quimioterapia adyuvante y en el 50% mediante resección transuretral de forma paliativa para conseguir el control de los síntomas. Se realizó una curva de supervivencia con los diferentes tratamientos realizados, presentando una supervivencia media global de 7 meses y sin observar diferencias estadísticamente significativas en cuanto a la supervivencia según el tratamiento realizado. Conclusiones: El carcinoma urotelial sarcomatoide es una enfermedad agresiva, de evolución rápida y tórpida que se produce en pacientes de edad avanzada y fumadores. No existen pautas de tratamiento establecidas y no parece que ningún tratamiento influya en un aumento de la supervivencia de los pacientes. Se debe de valorar la cistectomía como alternativa de tratamiento en aquellos pacientes de difícil control sintomatológico. Los diferentes componentes heterólogos no parecen influir en la evolución de la enfermedad ni en la supervivencia del paciente

Objective: Sarcomatoid urothelial bladder carcinoma comprises 3% of the tumours of the bladder and is considered one of the most aggressive tumours of the urinary tract. Our aim is to analyse the characteristics of sarcomatoid urothelial bladder carcinoma in adults, its treatments and survival. Method: A retrospective study performed between 2000 and 2017 of all the patients with a sarcomatoid urothelial bladder carcinoma in a single centre. We studied the anatomopathological characteristics, symptoms at time of diagnosis, treatment given and survival according to the treatment given. Results: Sixteen patients were diagnosed with sarcomatoid carcinoma, 11 with no heterologous component, one with rhabdomyosarcomatous components, 2 with chondrosarcomatous components and 2 with osteosarcomatous components. The mean age was 74 years (± 20) and 88% were smokers. The primary symptom was haematuria, and the least well-tolerated was dysuria together with hypogastric pain. Ninety-four percent of the patients had muscle layer infiltration and 18% had metastases at the time of diagnosis. Thirty-seven percent of the patients were treated by radical cystectomy, thirteen percent by radical cystectomy plus adjuvant chemotherapy, and 50% were treated by palliative transurethral resection to control their symptoms. A survival curve was made with the different treatments given, which showed a mean global survival of 7 months and no statistically significant differences in terms of survival according to the treatment given. Conclusions: Sarcomatoid urothelial carcinoma is an aggressive disease, of rapid and torpid onset which occurs in patients of advanced age and smokers. There are no established treatment guidelines, and it appears that no treatment influences increased survival. Cystectomy should be evaluated as a treatment alternative for patients whose symptoms are difficult to control. The various heterologous components do not appear to influence the progression of the disease or patient survival

[Polyarthritis secondary to intravesical BCG instillation, a case report]. / Poliartritis secundaria a instilaciones intravesicales de BCG, a propósito de un caso.

Immunotherapy with intravesical instillation of Bacillus Calmette is the best complementary after TUR treatment against T1 grade 2- 3 and CIS bladder cancer. However, this therapy is associated with several side- effects, incluiding joint symptoms. In this article we describe a case of polyarthritis associated with intravesical instillation, a rare complication. We review the clinical features, the pathogenic mechanisms and treatments described previously in the medical literature. Finally, we expose our brief experience and our final result.

La inmunoterapia endovesical con BCG es el mejor tratamiento complementario para tumores T1 G2-G3 y TiS. Sin embargo, esta terapia se ha asociado con diversos efectos secundarios, incluidos síntomas articulares. En este artículo, describimos un caso de poliartritis secundaria a instilaciones vesicales, una rara complicación. Realizamos una revisión de las manifestaciones clínicas, mecanismos de producción y tratamientos descritos con anterioridad en la literatura médica. Por último, exponemos nuestra breve experiencia y nuestro resultado final
