Résumé

ABSTRACT Purpose: In this study we aimed to review urological soft tissue sarcomas of genitourinary tract that were diagnosed in our institution and their prognostic factors for survival. Materials and Methods: The clinical and pathological records of 31 patients who had diagnosis of soft tissue sarcomas primarily originating from the genitourinary tract between 2005-2011 were reviewed. Results: The most common site was kidney (17 cases, 54.8%), and most common diagnosis was leiomyosarcoma (11 cases, 35.4%). A total of 24 patients (77.4%) had surgical excision. The surgical margins were positive in 7 patients who presented with local recurrence after primary resection. Twelve patients developed metastatic disease. During follow-up (range 9-70 month), 26 of the 31 patients (88.9%) were alive. Significant survival differences were found according to histological type (p: 0.001), with lower survival rates for malignant fibrous histiocytoma. The tumor size, the presence of metastasis at the time of diagnosis and tumor localization were not statistically significant for overall survival. Conclusions: In our series, prostate sarcomas, paratesticular rhabdomyosarcoma and malignant fibrous histiocytoma had poor prognosis, especially in patients presenting with metastatic disease.

Résumé

Abstract Aim Amyloid A amyloidosis is a rare complication of chronic inflammatory conditions. Most patients with amyloid A amyloidosis present with nephropathy and it leads to renal failure and death. We studied clinical characteristics and survival in patients with amyloid A amyloidosis. Methods: A total of 81 patients (51 males, 30 females) with renal biopsy proven amyloid A amyloidosis were analyzed retrospectively. The patients were divided into good and poor outcomes groups according to survival results. Results: Most of the patients (55.6%) had nephrotic range proteinuria at diagnosis. Most frequent underlying disorders were familial Mediterranean fever (21.2%) and rheumatoid arthritis (10.6%) in the good outcome group and malignancy (20%) in the poor outcome group. Only diastolic blood pressure in the good outcome group and phosphorus level in the poor outcome group was higher. Serum creatinine levels increased after treatment in both groups, while proteinuria in the good outcome group decreased. Increase in serum creatinine and decrease in estimated glomerular filtration rate of the poor outcome group were more significant in the good outcome group. At the time of diagnosis 18.5% and 27.2% of all patients had advanced chronic kidney disease (stage 4 and 5, respectively). Median duration of renal survival was 65 ± 3.54 months. Among all patients, 27.1% were started dialysis treatment during the follow-up period and 7.4% of all patients underwent kidney transplantation. Higher levels of systolic blood pressure [hazard ratios 1.03, 95% confidence interval: 1-1.06, p = 0.036], serum creatinine (hazard ratios 1.25, 95% confidence interval: 1.07-1.46, p = 0.006) and urinary protein excretion (hazard ratios 1.08, 95% confidence interval: 1.01-1.16, p = 0.027) were predictors of end-stage renal disease. Median survival of patients with organ involvement was 50.3 ± 16 months. Conclusion Our study indicated that familial Mediterranean fever constituted a large proportion of cases and increased number of patients with idiopathic amyloid A amyloidosis. Additionally, it was observed that patient survival was not affected by different etiological causes in amyloid A amyloidosis.


Resumo Objetivo: A amiloidose AA é uma complicação rara de condições inflamatórias crônicas. A maior parte dos pacientes com amiloidose AA apresenta nefropatia, que leva à insuficiência renal e à morte. Estudaram-se as características clínicas e a sobrevida em pacientes com amiloidose AA. Métodos: Analisaram-se retrospectivamente 81 pacientes (51 homens, 30 mulheres) com amiloidose AA comprovada por biópsia renal. Os pacientes foram divididos em grupos de desfecho bom e ruim de acordo com os resultados de sobrevida. Resultados: A maior parte dos pacientes (55,6%) tinha proteinúria na faixa nefrótica no momento do diagnóstico. Os distúrbios subjacentes mais frequentes foram a febre familiar do Mediterrâneo (FFM, 21,2%) e a artrite reumatoide (10,6%) no grupo de desfecho bom e a malignidade (20%) no grupo de desfecho ruim. Somente a pressão arterial diastólica no grupo de desfecho bom e o nível de fósforo no grupo de desfecho ruim foram mais elevados. Os níveis séricos de creatinina aumentaram após o tratamento em ambos os grupos, enquanto a proteinúria diminuiu no grupo de desfecho bom. O aumento na creatinina sérica e a diminuição na TFGe do grupo de desfecho ruim foram mais significativos no grupo de desfecho bom. No momento do diagnóstico, 18,5% e 27,2% de todos os pacientes tinham doença renal crônica avançada (estágios 4 e 5, respectivamente). A duração média da sobrevida renal foi de 65 ± 3,54 meses. Entre todos os pacientes, 27,1% iniciaram tratamento de diálise durante o período de seguimento e 7,4% de todos os pacientes foram submetidos a transplante renal. Níveis elevados de pressão arterial sistólica [taxas de risco (HR) 1,03, intervalo de confiança (IC) de 95%: 1 a 1,06, p = 0,036], creatinina sérica (HR 1,25, IC 95%: 1,07 a 1,46, p = 0,006) e excreção urinária de proteínas (HR 1,08, IC 95%: 1,01 a 1,16, p = 0,027) foram preditores de doença renal terminal. A mediana da sobrevida de pacientes com comprometimento de órgãos foi de 50,3 ± 16 meses. Conclusão: O presente estudo indicou que a FFM constituiu uma grande proporção de casos e crescente quantidade de pacientes com amiloidose AA idiopática. Adicionalmente, observou-se que a sobrevida do paciente não foi afetada pelas diferentes causas etiológicas na amiloidose AA.
