Evaluación de la biopsia de fusión elástica vs. biopsia sistemática para la detección del cáncer de próstata: resultados de un estudio multicéntrico en 1.119 pacientes / Elastic fusion biopsy versus systematic biopsy for prostate cancer detection: Results of a multicentric study on 1.119 patients

Objetivos: Evaluar la precisión de las biopsias guiada y sistemática para la detección del cáncer de próstata (CP) y CP clínicamente significativo (CPCS) en la práctica diaria, analizando el requerimiento de biopsias sistemáticas adicionales en el momento de la biopsia guiada. Pacientes y métodos: De nuestra base de datos multicéntrica que incluye 2.115 pacientes sometidos a biopsia de fusión con el sistema Koelis(TM) entre 2010 y 2017, seleccionamos 1.119 pacientes que recibieron biopsias guiadas (una mediana de 3 por cada lesión), con posterior muestreo sistemático (12 a 14 núcleos). Se evaluó la tasa de detección de cáncer (TDC) global y clínicamente significativa de las biopsias de fusión de Koelis(TM), comparando la biopsia guiada con la sistemática. Como objetivo secundario, está la identificación de los predictores de detección de CP. Resultados: La TDC de la biopsia guiada fue del 48% para todos los tipos de cáncer y del 33% para el CPCS. El muestreo de próstata sistemático adicional mejoró la TDC global en un 15% y en un 12% para CPCS. Se detectó CP en el 35, 69 y 92% de los pacientes con lesiones calificadas como PI-RADS 3, 4 y 5, respectivamente. Una puntuación elevada de PI-RADS y un examen rectal digital positivo fueron factores predictores de CP, y la condición «biopsia naïve» se asoció con CPCS. Conclusión: En la práctica diaria, la biopsia guiada con Koelis(TM) logra una buena TDC para todos los CP y CPCS, y mejora significativamente con el muestreo sistemático posterior de la próstata. Los excelentes resultados de la biopsia por fusión se confirman también en pacientes naïve. La puntuación PI-RADS elevada y el examen rectal digital positivo están altamente asociados con la presencia de CP

Objectives: To assess the accuracy of targeted and systematic biopsies for the detection of prostate cancer (PCa) and clinically significant PCa (csPCa) in the everyday practice, evaluating the need for additional systematic biopsies at the time of targeted biopsy. Patients and methods: From our multicentric database gathering data on 2,115 patients who underwent fusion biopsy with Koelis(TM) system between 2010 and 2017, we selected 1,119 patients who received targeted biopsies (a median of 3 for each target), followed by systematic sampling of the prostate (12 to 14 cores). Overall and clinically significant cancer detection rate (CDR) of Koelis(TM) fusion biopsies were assessed, comparing target and systematic biopsies. Secondary endpoint was the identification of predictors of PCa detection. Results: The CDR of targeted biopsies only was 48% for all cancers and 33% for csPCa. The performance of additional, systematic prostate sampling improved the CDR of 15% for all cancers and of 12% for csPCa. PCa was detected in 35%, 69%, and 92% of patients with lesions scored as PI-RADS 3, 4 and 5, respectively. Elevated PI-RADS score and positive digital rectal examination were predictors of PCa, whereas biopsy-naïve status was associated with csPCa. Conclusion: In the everyday practice target biopsy with Koelis(TM) achieves a good CDR for all PCa and csPCa, which is significantly improved by subsequent systematic sampling of the prostate. The outstanding outcomes of fusion biopsy are confirmed also in biopsy-naïve patients. Elevated PI-RADS score and positive digital rectal examination are strongly associated with presence of PCa

A multicentric study on accurate grading of prostate cancer with systematic and MRI/US fusion targeted biopsies: comparison with final histopathology after radical prostatectomy.

OBJECTIVE: To evaluate the accuracy in histologic grading of MRI/US image fusion biopsy by comparing histopathology between systematic biopsies (SB), targeted biopsies (TB) and the combination of both (SB + TB) with the final histopathologic outcomes of radical prostatectomy specimens. MATERIALS AND METHODS: Retrospective, multicentric study of 443 patients who underwent SB and TB using MRI/US fusion technique (Urostation® and Trinity®) prior to radical prostatectomy between 2010 and 2017. Cochran's Q test and McNemar test were conducted as a post hoc test. Uni-multivariable analyses were performed on several clinic-pathological variables to analyze factors predicting histopathological concordance for targeted biopsies. RESULTS: Concordance in ISUP (International Society of Urological Pathology) grade between SB, TB and SB + TB with final histopathology was 49.4%, 51.2%, and 63.2% for overall prostate cancer and 41.2%, 48.3%, and 56.7% for significant prostate cancer (ISUP grade ≥ 2), respectively. Significant difference in terms of concordance, downgrading and upgrading was found between SB and TB (ISUP grade ≥ 2 only), SB and SB + TB, TB and SB + TB (overall ISUP grade and ISUP grade ≥ 2) (p < 0.001). Total number of cores and previous biopsies were significant independent predictive factors for concordance with TB technique. CONCLUSION: In this retrospective study, combination of SB and TB significantly increased concordance with final histopathology despite a limited additional number of cores needed.

[Laparoscopic radical cystectomy in elderly patients with bladder cancer: feasibility and evaluation of morbidity]. / Cystectomie radicale coelioscopique pour cancer de vessie, chez les sujets de plus de 70ans : faisabilité et étude de la morbidité

OBJECTIVES: To evaluate the feasibility and morbidity and mortality of laparoscopic radical cystectomy for bladder cancer in elderly patients. METHODS: Prospective study conducted between January 2003 and May 2009 in 22 patients, one woman and 21 men, who underwent laparoscopic radical cystectomy for bladder cancer. Mean patient age was 76.2+/-4.3 years. The median preoperative ASA score was 2 (1-3). The indication for surgery was an invasive muscle bladder tumour in 18 cases and noninvasive muscle bladder cancer refractory to conservative treatment (chemotherapy, immunotherapy) in four cases. Ileal conduit was carried out in 15 cases. An ileal neobladder was fashioned in six cases using Camey's technique. One bilateral cutaneous ureterostomy was performed. RESULTS: There was one conversion to open surgery. One intraoperative complication was noted (left obturator nerve injury). Mean blood loss was 377.5+/-341.2ml. No perioperative death was observed. Mean time to resumption of oral fluids was 2.4+/-1.6 days and mean time to resumption of solids was 4.5+/-1.6 days. Mean time to resumption of bowel movements was 3.9+/-1.9 days. Mean critical care unit was 4.2+/-1.4 days. Five patients (22.7 %) had postoperative complications. Postoperative narcotic analgesics were necessary in 60 % of cases. Mean hospital stay was 11.0+/-3.0 days. Mean patient follow-up was 46.4+/-20.8 months. CONCLUSIONS: Laparoscopic radical cystectomy for bladder cancer in elderly patients is associated with low morbidity, and a limited hospital stay.

[Pathological stage T3 prostate cancer after radical prostatectomy: a retrospective study of 246 cases]. / Cancer de la prostate de stade pT3 après prostatectomie totale : étude rétrospective de 246 cas.

OBJECTIVE: To determine the survival and prognosis criteria of pT3NxM0 prostate tumours (TNM 2002) after radical retropubic prostatectomy (RRP). MATERIAL AND METHODS: Between 1988 and 2000, 606 consecutive RRP were performed for T1-3 tumours, whose 246 (40.6%) specimens were classified pT3, followed in 53 cases by adjuvant radiotherapy and in 71 cases by salvage radiotherapy. Fifty-five patients received postoperative hormonotherapy at the time of biochemical recurrence. Biochemical recurrence was determined by two PSA values greater than 0.2 ng/ml. RESULTS: Mean age of this group was 65 years at surgery. Mean follow-up was 91.4 months. Mean preoperative PSA was 12.8 ng/ml. Distribution of cases was 170 pT3a (69.1%) and 76 (30,9%). At 10 years, the biochemical progression-free, metastasis-free, specific and overall survival was 54, 86, 92 and 75% respectively. Worse biochemical prognostic factors were lymph node extension, high Gleason score, high preoperative PSA, seminal vesicles involvement, positive surgical margins and adjuvant radiotherapy absence. CONCLUSION: This study shows that pT3 tumours treated with therapeutic associations including RRP presents an excellent specific survival at 10 years. The determination of biochemical recurrence prognostic factors could help to select patients who need complementary treatments after surgery.

[Benign urachus abnormalities: embryology, diagnosis and treatments]. / Pathologies bénignes de l'ouraque chez l'adulte : origine embryologique, présentation clinique et traitements.

Urachus pathologies are very rare but require to be known by urologists. Lack of appropriate treatment exposes the patients to the risks of symptoms recurrence, infectious complications or adenocarcinomatous degeneration. A partial or total defect of obliteration of the urachus channel after the fifth month of gestation can be at the origin of four benign pathologies. The ombilicovesical fistula (47.6%) is diagnosed at the native period. In the adult, the most frequent form is the cyst (30.7%) whereas the external (16.4%) and internal sinus (3.2%) are rarer. Diagnosis depends on the clinical examination and the association of sonography and TDM. The risk of complications must systematically result in proposing a surgical treatment for these benign pathologies. The umbilicus resection is not recommended, but the surgeon has to remove the urachus and its implantation base on the bladder. Laparoscopic surgery seems to be an interesting route for this intervention.
