ABSTRACT

Introdução: O câncer renal corresponde a 13ª neoplasia mais incidente no mundo, sendo o terceiro tipo de câncer geniturinário mais comum. A maioria dos pacientes é assintomática, ocorrendo o diagnóstico de maneira incidental durante a realização de exames de imagem. O tratamento padrão-ouro é o cirúrgico. Objetivo: Correlacionar os parâmetros clínicos e patológicos com a sobrevida livre de doença em pacientes com câncer renal submetidos à nefrectomia. Método: Estudo retrospectivo com 99 pacientes submetidos a tratamento cirúrgico do câncer renal no período de 2010 a 2020. Foram comparados os parâmetros clínicos e patológicos com o desfecho clínico oncológico após nefrectomia. Resultados: Os 99 pacientes tiveram seguimento pós-operatório médio de 26,9 meses, sendo a sobrevida livre de doença (média) de 61,9%. A análise univariada demonstrou que as variáveis tamanho de tumor >7 cm e graus de Fuhrman III e IV estiveram relacionadas à progressão de doença após a nefrectomia (p=0,046 e IC=1,017-7,083; p=0,005 e IC=1,725-23,004, respectivamente). Na análise multivariada, o tamanho do tumor >7 cm (p=0,014 e IC=1,290-9,326) e os graus de Fuhrman III e IV (p=0,028 e IC=1,174-16,616) foram identificados como fatores preditores à progressão. Conclusão: O tamanho tumoral >7 cm e/ou os graus III ou IV de Fuhrman são fatores de risco para recorrência tumoral após o tratamento cirúrgico do câncer renal


Introduction: Kidney cancer corresponds to the 13th most incident cancer in the world, and the third most common type of genitourinary cancer. Most patients are asymptomatic, and the diagnosis used to be incidental during routine imaging exams. Surgical treatment is the gold standard. Objective: To correlate clinical and pathological parameters with diseasefree survival in renal cancer patients submitted to nephrectomy. Method: Retrospective study with 99 patients who underwent surgical treatment of kidney cancer from 2010 to 2020. Clinical and pathological parameters were compared with the clinical oncologic outcome after surgery. Results: Ninety-nine patients were followed-up postoperatively for an average time of 26.9 months, and the mean disease-free survival was 61.9%. Univariate analysis showed that tumor size >7 cm and Fuhrman grades III and IV were risk factors related to disease progression after nephrectomy (p=0.046 and CI=1.017-7.083; p=0.005 and CI=1.725-23.004, respectively). In the multivariate analysis, tumor size > 7cm (p=0.014 and CI=1.290-9.326) and Fuhrman grades III and IV (p=0.028 and CI=1.174-16.616) were identified as predictors of progression. Conclusion: Tumor size >7 cm and/or Fuhrman grades III or IV are risk factors for tumor recurrence after surgical treatment of renal cancer


Introducción: El cáncer de riñón corresponde a la 13ª neoplasia más incidente en el mundo, siendo el tercer tipo de cáncer genitourinario más común. La mayoría de los pacientes son asintomáticos, realizándose el diagnóstico de forma incidental durante las pruebas de imagen. El tratamiento estándar de oro es el quirúrgico. Objetivo: Correlacionar parámetros clínicos y patológicos con la supervivencia libre de enfermedad en pacientes con cáncer renal sometidos a nefrectomía. Método: Estudio retrospectivo con 99 pacientes sometidos a tratamiento quirúrgico de cáncer renal desde 2010 hasta 2020. Se compararon los parámetros clínicos y patológicos con el resultado clínico oncológico tras la nefrectomía. Resultados: Los 99 pacientes tuvieron un seguimiento postoperatorio medio de 26,9 meses, siendo la supervivencia libre de enfermedad (mediana) de 61,9%. El análisis univariado demostró que las variables tamaño del tumor >7 cm y grados III y IV de Fuhrman fueron factores relacionados con la progresión de la enfermedad tras la nefrectomía (p=0,046 e IC=1,017-7,083; p=0,005 e IC=1,725-23,004, respectivamente). En el análisis multivariante, el tamaño del tumor >7 cm (p=0,014 e IC=1,290-9,326) y grados de Fuhrman III y IV (p=0,028 e IC=1,174-16,616) fueron identificados como predictores de progresión. Conclusión: El tamaño tumoral >7 cm y/o los grados III o IV de Fuhrman son factores de riesgo para la recidiva tumoral tras el tratamiento quirúrgico del cáncer renal

ABSTRACT

Introdução: O câncer de próstata é a neoplasia maligna mais incidente em homens, representando 29% dos diagnósticos da doença no Brasil, segundo o Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA). Esse câncer é suspeito em alterações do toque retal e/ ou do nível sérico do antígeno prostático específico (PSA) total, sendo o diagnóstico definitivo feito por estudo histopatológico. Objetivo: Verificar a associação entre parâmetros clínicos e anatomopatológicos após prostatectomia radical com recidiva bioquímica ao longo do seguimento. Método: Estudo retrospectivo observacional dos parâmetros clínicos (idade, PSA inicial, toque retal, classificação histopatológica da International Society of Urological Pathology (ISUP), escala de D'Amico e estádio clínico) e anatomopatológicos (grau ISUP da peça cirúrgica, margens cirúrgicas, extensão extracapsular tumoral e presença de linfonodos acometidos), de 177 pacientes submetidos à prostatectomia radical em serviço de uro-oncologia de junho/2010-maio/2018. Resultados: A recidiva bioquímica ocorreu em 44,1% dos casos no tempo de seguimento médio de 34,9 meses. A análise univariada demonstrou PSA inicial >9 ng/mL, toque retal alterado, classificação patológica ISUP 4 e 5, risco D'Amico alto e estágio clínico TNM T3 como fatores diretamente associados à recidiva bioquímica. As margens cirúrgicas foram positivas em 46,3%; em 47,7%, identificou-se extensão extraprostática tumoral. Linfonodos positivos em 10,9% e vesículas seminais comprometidas ocorreram em 21,8%. Conclusão: Fatores clínico-patológicos podem ser preditores de recidiva bioquímica. Nesses casos, foi identificado padrão clínico pré-tratamento supostamente mais agressivo em comparação à literatura em geral. Além disso, deve-se considerar a curva de aprendizado dos cirurgiões em formação no serviço, o que pode resultar em maiores taxas de margens cirúrgicas positivas


Introduction: Prostate cancer is the most common cancer in men representing 29% of diagnoses of the disease in Brazil according to the National Cancer Institute José Alencar Gomes da Silva (INCA). If digital rectal examination presents alterations and/or altered serum level of prostate-specific antigen (PSA) total is detected, there is suspicion of prostate cancer, but the definitive diagnosis occurs only with histopathological study. Objective: To correlate clinical and pathological parameters after radical prostatectomy with biochemical recurrence during follow-up. Method: Retrospective observational study of clinical parameters (age, initial PSA, digital rectal examination, histopathological classification of the International Society of Urological Pathology (ISUP), D'Amico scale and clinical stage) and pathological (ISUP degree of the surgical specimen, surgical margins, extracapsular tumor extension and presence of positive lymph nodes) of 177 patients who underwent radical prostatectomy in an uro-oncology service from June 2010 to May 2018. Results: Biochemical recurrence occurred in 44.1% of the cases within a mean follow-up time of 34.9 months. Univariate analysis showed that baseline PSA>9 ng/mL, altered rectal examination, pathological ISUP classification 4 and 5, high D'Amico risk, and clinical TNM stage T3 are risk factors for biochemical recurrence. Surgical margins were positive in 46.3%, and in 47.7% extracapsular extension was identified. Positive lymph nodes were detected in 10.9% and positive seminal vesicles occurred in 21.8%. Conclusion: Clinical and pathological factors can be predictors of biochemical recurrence. In these cases, it was identified a more aggressive clinical pattern than the literature in general. In addition, it should be considered the learning curve of surgeons in training at the service, which can result in higher rates of positive surgical margins


Introducción: El cáncer de próstata es lo más incidente en hombres representando 29% de los diagnósticos de enfermedades en Brasil según Instituto Nacional del Cáncer José Alencar Gomes da Silva (INCA), se sospecha en tacto rectal y/o en el nivel de análisis del antígeno prostático específico (PSA) total alterado, y el diagnóstico definitivo se realiza mediante el estudio histopatológico. Objetivo: Correlacionar los parámetros clínicos y patológicos después de la prostatectomía radical con la recurrencia bioquímica a lo largo del seguimiento. Método: Estudio observacional retrospectivo de parámetros clínicos (edad, PSA inicial, tacto rectal, clasificación histopatológica de la International Society of Urological Pathology (ISUP), escala D'Amico y estadio clínico) y patológicos (grado ISUP de la muestra quirúrgica, márgenes quirúrgicos, extensión capsular tumoral extra y ganglios linfáticos positivos) de 177 pacientes sometidos a prostatectomía radical en servicio de uro-oncología de junio/2010-mayo/2018. Resultados: La recurrencia bioquímica ocurrió en el 44,1% de los casos en un tiempo de seguimiento promedio de 34,9 meses. El análisis univariado demostró que el PSA inicial >9 ng/mL, alteración del tacto rectal, clasificación patológica ISUP 4 y 5, alto riesgo de D'Amico y estadificación TNM clínico T3 como factores de riesgo para recurrencia bioquímica. Los márgenes quirúrgicos fueron positivos en el 46,3%, y en el 47,7% se identificó una extensión extra capsular adicional. Los ganglios linfáticos positivos fueron detectados en 10,9% y las vesículas seminales positivas ocurrieron en el 21,8%. Conclusión: Los factores clínicos y patológicos pueden ser predictores de recurrencia bioquímica. En estos casos, fue identificado un patrón más agresivo que la literatura en general. Además, se debe considerar la curva de aprendizaje de los cirujanos en formación en el servicio, lo que puede resultar en mayores tasas de márgenes quirúrgicos positivos

ABSTRACT

PURPOSE:: To analyze the influence of chlorpromazine on renal histology of rats submitted to ischemia and reperfusion injury. METHODS:: Sixteen Wistar rats - split in two groups - have been used: control group, receiving 3 mg/kg isotonic saline solution through caudal vein, and, the chlorpromazine group, receiving 3 mg/kg-IV of such medication. The nephrectomy of the left kidney lower third was carried out; immediately, the test-drug was administrated. After 15 minutes of test-drug administration, the renal pedicle was clamped; in 60 minutes of ischemia it was released. After 24 hours of the renal reperfusion, the rats were, once more, anesthetized and submitted to total left nephrectomy, and, afterwards, to euthanasia. Histological findings regarding ischemia have been evaluated and compared between the groups. RESULTS:: There was no statistical difference related to inferior renal pole histological analysis. Regarding 60-minute renal ischemia, chlorpromazine has statistically reduced the accrual of leucocytes within the vasa recta renis (p=0.036) and the congestion of peritubular capillaries (p=0.041). When conducting joint analysis of histological patterns, the control group showed a median score of 11 and chlorpromazine group of 5.5 (p=0.036). CONCLUSION:: Chlorpromazine significantly reduced the occurrence of secondary damage to ischemia and reperfusion process in the overall histological analysis.
