RESUMO
PURPOSE: We report oncologic outcomes in patients treated with focal therapy for prostate cancer. MATERIALS AND METHODS: We retrospectively analyzed a single institution cohort of men with localized prostate cancer who received focal therapy using high intensity focused ultrasound or cryotherapy from 2009 to 2018. Focal therapy was offered for low or intermediate risk disease (prostate specific antigen less than 20 ng/ml, Gleason score 7 or less and clinical stage T2b or less). Patients with previous prostate cancer treatment or less than 6 months of followup were excluded from study. Failure was defined as local or systemic salvage treatment, a positive biopsy Gleason score of 7 or greater in-field or out-of-field in nontreated patients, prostate cancer metastasis or prostate cancer specific death. Cox regression analysis was done to identify independent predictors of failure after focal therapy. RESULTS: Of the 309 patients included in study 190 and 119 were treated with high intensity focused ultrasound and cryotherapy, respectively. Median followup was 45 months. At 1, 3 and 5 years the failure-free survival rate was 95%, 67% and 54%, and the radical treatment-free survival rate was 99%, 79% and 67%, respectively. The 5-year metastasis-free survival rate was 98% and no prostate cancer specific death was registered in this cohort. Before focal therapy a biopsy Gleason score of 7 (3 + 4) or greater (HR 2.4, p <0.001) and nadir prostate specific antigen (HR 2.2, p <0.001) were independently associated with failed focal therapy. In the salvage focal therapy setting in-field recurrence after primary focal therapy was associated with poorer failure-free survival (p=0.02). CONCLUSIONS: Almost half of the men were free of focal therapy failure 5 years after treatment. Still, a significant proportion experienced recurrence at the midterm followup. The preoperative biopsy Gleason score and nadir prostate specific antigen were significantly associated with treatment failure.

PURPOSE: To provide data of the incidence and management of common urological malignancies in renal transplant recipients. MATERIALS AND METHODS: We conducted a retrospective analysis of a prospective database from August 1967 to August 2015. A descriptive analysis of the sample was performed. RESULTS: Among 1256 consecutive RTR a total of 88 patients developed malignancies (7%). There were 18 genitourinary tumors in the 16 patients (20.45% of all malignant neoplasms), incidence of 1.27%. The most common neoplasm encounter was renal cancer (38.8%), followed by urothelial carcinoma (33.3%). Median follow up of transplantation was 197 months (R, 36-336). Mean time from RT to cancer diagnosis 89±70 months (R, 12-276). CsA and AZA was the most common immunosuppression regimen in 68.75%. Mean follow-up after diagnosis was 103±72 months (R 10-215). Recurrence free survival rate of 100%. Overall survival of 89.5% of the sample; there were two non-related cancer deaths during follow up. CONCLUSIONS: The incidence of neoplasms in RTR was lower than in other series, with favorable functional and oncologic results after treatment. This suggests that actions to reduce the risk of these malignancies as well as a strict follow-up are mandatory for an early detection and treatment.

OBJECTIVE: High-intensity focused ultrasound (HIFU) Focal therapy appears to have encouraging oncologic outcomes and urinary and erectile function. The control of the treated area can be done using contrast enhanced ultrasound with sulfur hexafluoride (Sonovue®) at the end of the procedure. We report oncological and functional outcomes in HIFU focal therapy (FT) for prostate cancer (PCa) management using sonovue. METHODS: A total of 274 HIFU procedures were found in our registry in the period between June 2014 and July 2018. Prospective data of 59 consecutive patients after focal high-intensity focused ultrasound (HIFU) using Sonovue were collected. FT failure was defined as positive biopsy Gleason score (GS) ≥ 7 in- or out-field, local or systemic salvage treatment, PCa-metastasis or PCa-specific death. RESULTS: A total of 59 patients submitted to HIFU with median follow-up of 18 months were included in the analysis. Median age was 66.7 yr (IQR 59.1-74.3). Median preoperative prostate-specific antigen (PSA) was 7.6 ng/ml (IQR 5-10.2) and preoperative biopsies GS 6, 7(3+4), 7(4+3) were found in 26 (44%), 30 (50.8%) and 3 (5%), respectively. Failure was found in 16 (27.1%) patients. Failure-free survival (FFS) in 2 and 4yr was 83% and 74% respectively (Figure 1). No PCa-specific death was registered in the period of study. Median nadir PSA after FT was 2.67 ng/ml. Sexual potency was achieved in 75% of previous potent patients and urinary continence in 93.4% of patients at 3 months. Fourteen (23%) patients presented with complications. Four (6.7%) patients have presented complications grade 1 and 10 (16.9%) patients have presented complications grade 2. Six (10.1%) patients have presented acute urinary retention. CONCLUSIONS: Our study shows that the use of Sonovue after HIFU FT was safe. Patients present a significant proportion of failure after HIFU FT but with good functional outcomes and without incidence of severe complications.
OBJETIVOS: La terapia focal con HIFU (High-intensity focused ultrasound) parece tener unos resultados oncológicos y de función urinaria y eréctil prometedores. El control del área tratada puede realizarse al final de la intervención utilizando Sonovue®, el contraste de ecografía con hexafluoruro de azufre. Presentamos los resultados oncológicos y funcionales de la terapia focal con HIFU en el tratamiento cáncer de próstata utilizando Sonovue.MÉTODOS: Se encontraron en nuestro registro un total de 274 intervenciones con HIFU entre Junio 2014 y Julio 2018. Se recogieron los datos prospectivamente en 59 pacientes consecutivos después de HIFU utilizando Sonovue. Se define fracaso de la terapia focal como biopsia positiva con puntuación de Gleason (GS) >7 dentro o fuera del campo, tratamiento de salvamento local o sistémico, metástasis del CaP o muerte cáncer específica por CaP. RESULTADOS: Se incluyeron en el análisis un total de 59 pacientes sometidos a HIFU con una mediana de seguimiento de 18 meses. La mediana de edad fue 66,7 años (Rango intercuartílico (RIC) 59,1-74,3). La mediana de PSA preoperatorio fue 7,6 ng/mL (RIC 5-10,2) y las biopsias fueron GS 6, 7 (3+4) y 7 (4+3) en 26 (44%), 30 (50,8%) y 3 (5%) casos, respectivamente. En 16 pacientes (27,1%) fracasó el tratamiento. La supervivencia libre de fracaso del tratamiento a 2 y 4 años fue 83% y 74% respectivamente (Figura 1). No se ha registrado ninguna muerte cáncer específica por el CaP en el periodo de estudio. La mediana del nadir de PSA después de la terapia focal fue 2,67 ng/ml. El 75% de los pacientes previamente potentes consiguieron mantener su potencia sexual y el 93,4% eran continentes a los 3 meses. Catorce pacientes (23%) presentaron complicaciones. Cuatro (6,7%) presentaron complicaciones grado 1 y 10 (16,9%) grado 2. Seis pacientes (10,1%) presentaron retención aguda de orina. CONCLUSIONES: Nuestro estudio muestra que el uso de Sonovue después de terapia focal con HIFU es seguro. Los pacientes presentan una proporción significativa de fracasos después de terapia focal con HIFU aunque tiene buenos resultados funcionales y sin incidencia de complicaciones graves.
