Palliative embolization of renal tumors

Abstract

Our results are consistent with data in the literature. Survival in patients without metastases was longer than in those with metastases, as confirmed by the 14 of the patients from the study. An additional therapeutic safety in the treatment of small cancers is provided with a combination therapy of embolization and radiofrequency thermoablation.

Embolización de la arteria renal: Serie de casos y revisión de la literatura

“…Otros estudios que incluían pacientes con otras indicaciones, además de hematuria, de embolización de arteria renal, también mostraron su efectividad y su baja tasa de complicaciones 1,4,[32][33][34][35][36] . Por otro lado, los resultados de los análisis retrospectivos son a veces inconsistentes y no hay ensayos prospectivos aleatorizados que comparen los parámetros quirúrgicos entre los subgrupos que se embolizan y los que no 1 .…”

“…Desde la descripción de la embolización percutánea de arterias renales en animales en 1969 por Lalli et al 3 , y la primera descrita en humanos en 1973 por Almgard et al 4,5 , se han descrito múltiples indicaciones, siendo la hematuria y el manejo paliativo en cáncer renal metastásico las más clásicas. Sin embargo, existen otras indicaciones: terapia adyuvante en cáncer renal (citorreducción), contraindicación anestésica o rechazo por el paciente de nefrectomía quirúrgica, tratamiento de angiomiolipomas, malformaciones arteriovenosas, fístulas arteriovenosas, enfermedad renal médica, trauma, complicaciones postrasplante, entre otras 1,2,6 .…”

Renal Arteries Embolization in Unresectable Clear Cell Renal Carcinoma: First Time Experience at Haji Adam Malik Hospital

“…In the literature, for kidney cancer cases, there is no specific agent recommended to have a better effectivity than others. In our institution, we use polyvinyl alcohol as embolant agent [ 12 ] [ 13 ]. Foam forms of PVA were first used in the 1970’s [ 14 ].…”

Effect of renal embolization in patients with synchronous metastatic renal cell carcinoma: A retrospective comparison of cytoreductive nephrectomy and systemic medical therapy

“…RE can be used to treat patients with large unresectable smRCC, intravenocaval thrombosis or extensive lymphadenopathy, with outcomes expected to be comparable to those obtained with CN [7,9]. The RE procedure can be performed either preoperatively to facilitate surgery or as palliative treatment to control symptoms, such as pain and hematuria [6,10]. RE is also indicated for patients with a short life expectancy, due to major comorbidities or poor general condition, and for those unsuitable for general anesthesia [11,12].…”

“…However, in the absence of randomized clinical trials, controversy persists regarding the prognostic benefits of CN in the era of TT. Renal arterial embolization (RE) provides an alternative treatment option for high risk patients who have symptomatic unresectable mRCC or who are unsuitable for surgery due to multiple comorbidities and poor functional status [6,7]. However, the efficacy of RE compared to that of CN in improving survival has yet to be evaluated.…”
