ABSTRACT

PURPOSE: We evaluated the role of several prognostic factors in predicting death and/or progressive disease in patients with renal cell carcinoma. MATERIALS AND METHODS: Between 2004 and 2010, 227 consecutive patients with renal cell carcinoma underwent radical nephrectomy at our Institute. All histological specimens were examined by the same pathologist. We considered certain histological parameters, including histological subtype, conventional Fuhrman grade, presence of sarcomatoid features, adrenal gland infiltration, invasion of the perinephric fat, vascular embolization, collecting system invasion, presence or absence of tumour necrosis (0%, 1% to 49%, or 50% or greater) and regional lymph node metastasis. RESULTS: Variables significantly associated with death and/or progressive disease on univariate analysis were histological subtype (p = 0.006), Fuhrman grade (p < 0.0001), tumor necrosis (p = 0.009), perinephric fat invasion (p = 0.002), vascular embolization (p = 0.0002), presence of lymph node involvement (p < 0.002), tumor size (p = 0.0006), TNM stage (p < 0.00001) and presence of metastasis (p < 0.00001). In the multivariable model histological subtype, tumor necrosis, lymph node involvement and presence of metastasis were independent risk factors for disease-free survival (p = 0.011, 0.042, 0.025 and p < 0.0001, respectively). CONCLUSION: Histological subtype, tumor necrosis, lymph node involvement and presence of metastasis proved to be independent prognostic factors for disease-free survival. Therefore, the presence and rate of tumor necrosis should always be informed by the pathologist and lymphadenectomy should be performed in all patients.

ABSTRACT

Melanomas do pênis são tumores malignos muito agressivos. Descrevemos o caso de um paciente com uma lesão confinada ao prepúcio e com linfonodos inguinais clinicamente negativos, tratados conservadoramente. O pacientesubmeteu-se à ressecção alargada da lesão para tratamento e diagnóstico. O tratamento das regiões inguinais em pacientes com melanoma de pênis permanece controvertido, uma vez que a incidência de doença metastática é significativamente mais baixa nos pacientes com estádios patológicos iniciais. Como nesse paciente o estádio patológico do melanoma de pênis era T2a (profundidade 1,9 mm, sem ulceração), decidimos usar linfocintigrafia pré-operatória, mapeamento intra-operatório dos linfonodos e biópsia do linfonodo sentinela para avaliar o comprometimento metastático inguinal. Cortes de congelação do linfonodo sentinela direito retirado foram negativos para malignidade e nenhum tratamento adjuvante foi realizado. A ressecção alargada da lesão permitiu efetivocontrole local do tumor peniano e o paciente é mantido em acompanhamento clínico pós-operatório.


Melanomas of the penis are highly aggressive malignant tumors. We report on a patient with a lesion confined tothe prepuce and with clinically negative inguinal lymph nodes, treated conservatively. The patient underwent wide local excision (WLE) for treatment and histological diagnosis. Treatment of the inguinal region in patients withpenile melanoma remains controversial, since the incidence of metastatic disease in those with early pathologicalstagedisease is significantly lower. Since our patient presented penile melanoma pathological stage T2a (depth 1.9mm, without ulceration), we chose to use pre-operative lymphoscintigraphy, intra-operative lymph node mapping,and sentinel node biopsy to evaluate inguinal metastatic involvement. Frozen sections in an excised right sentinelnode were negative, and no adjuvant treatment was performed. WLE provided effective local control of the peniletumor, and the patient remains under postoperative surveillance.

ABSTRACT

Um segmento de íleo e de cólon é utilizado para criar uma neobexiga, após cistectomia com uma anastomose ceco-uretal. Esta técnica cirúrgica denominada Mainz Pouch utiliza 15 cm de ceco e cólon ascendente e duas alças ileais do mesmo comprimento para a construçäo de um reservatório urinário. Esta neobexiga permite a continência urinária, um grande reservatório de baixa pressäo, o esvaziamento vesical voluntário e o reimplante uretral com técnica anti-refluxo. Quatro pacientes foram submetidos a este procedimento após a cistoprostatectomia, poupando-se, porém, a inervaçäo responsável pela ereçäo. O seguimento destes pacientes variou entre oito e 14 meses. Os quatro pacientes estäo continentes, durante os períodos diurno e noturno. Três esvaziam suas neobexigas espontaneamente, em intervalos normais. Um paciente tem ereçöes e relaçöes sexuais.
