[French ccAFU guidelines - update 2020-2022: management of kidney cancer]. / Recommandations françaises du Comité de cancérologie de l'AFU ­ actualisation 2020­2022 : prise en charge du cancer du rein.

OBJECTIVE: - To update the French guidelines on kidney cancer. METHODS: - A systematic review of the literature between 2015 and 2020 was performed. The most relevant articles regarding the diagnosis, the classification, surgical treatment, medical treatment and follow-up of kidney cancer were retrieved and included in the new guidelines. The guidelines were updated with corresponding levels of evidence. RESULTS: - Thoraco-abdominal CT scan with injection is the best radiological exam for the diagnosis of kidney cancer. MRI and contrast ultra-sound can be useful in some cases. Percutaneous biopsy is recommended when histological results will affect clinical decision. Renal tumours must be classified according to pTNM 2017 classification and ISUP grade. Metastatic kidney cancers must be classified according to IMDC criteria. Partial nephrectomy is the recommended treatment for T1a tumours and can be done through an open, laparoscopic or robotic access. T1b tumours can be treated by partial or total nephrectomy according to tumour complexity. Radical nephrectomy is the recommended treatment of advanced localized tumours. There is no recommended adjuvant treatment. In metastatic patients: cyto-reductive nephrectomy can be offered in case of good prognosis; medical treatment must be counseled first in case of intermediate or bad prognosis. Surgical or local treatment of metastases should be considered in case of solitary lesion or oligo-metastases. First line recommended drugs in metastatic patients include the associations axitinib/pembrolizumab and nivolumab/ipilimumab. Cystic tumours must be classified according to Bosniak Classification. Surgical excision should be offered to patients with Bosniak III and IV lesions. It is recommended to follow patients clinically and with imaging according to tumour aggressiveness. CONCLUSION: - These updated recommendations should assist French speaking urologists for their management of kidney cancers.

Long-term oncological outcomes of cystic renal cell carcinoma according to the Bosniak classification.

OBJECTIVES: To evaluate the prognostic role of the Bosniak classification on the long-term oncological outcomes of cystic renal cell carcinomas. MATERIAL AND METHOD: In a national multicentric retrospective study, we included patients treated surgically for localized cystic RCC from 2000 to 2010. Patients with a follow-up of less than 4 years, benign tumors, and ablative treatments were excluded. The primary outcome was disease-free survival. RESULTS: 152 patients met the inclusion criteria: Bosniak II (6%), III (53%), IV (41%), with a median follow-up of 61 (12-179) months. Characteristics of the population and the tumors were [median, (min-max)] age 57 (25-84) years old, tumor size 43 mm (20-280), RENAL score 7 (4-12), PADUA score 8 (5-14). Treatments were 55% partial nephrectomy, 45% radical nephrectomy, 74% open surgery, and 26% laparoscopy. In pathological report, cystic RCC were mainly of low grade (1-2, 77%) and low stage (pT1, 81%). The two main histological subtypes were conventional (56%) and papillary (23%) RCC. Staging at presentation and histological characteristics were similar between Bosniak III and IV, except for high grade which was more common in Bosniak IV (12 vs 36%, p < 0.01). The Bosniak classification was not predictive of the recurrence, as 5- and 10-year disease-free survival were similar in Bosniak III and IV (92% vs 92% and 84% vs 83%, p = 0.60). CONCLUSION: The Bosniak classification is predictive of the risk of malignancy but not of the oncological prognosis. Regardless of the initial Bosniak categories, almost all cystic RCCs were of low stage/grade and had low long-term recurrence rate.

[Salvage cryotherapy of prostate cancer after failed external radiotherapy and brachytherapy: Morbidity and mid-term oncological results]. / Cryothérapie prostatique de rattrapage après échec de radiothérapie externe ou curiethérapie : morbidité et résultats oncologiques à moyen terme.

OBJECTIVE: To study the oncologic and functional results of salvage cryotherapy after failure of external radiotherapy and brachytherapy. MATERIALS AND METHODS: Patients treated by total salvage cryotherapy (3rd generation) in 2 centers (Groupe Hospitalier Saint-Joseph in Paris and Clinique Jule-Verne Nantes) in between January 2008 and April 2016 were included. The biochemical recurrence-free survival (BRFS) was calculated using the Phoenix criteria (PSA>nadir+2ng/mL). The functional results were assessed clinically. RESULTS: Ninety-seven patients with an average follow up of 39.4months were evaluated retrospectively. The 5-year biochemical recurrence-free survival (5y-BRFS) among all patients was 58.1% (IC à 95% [45.9-68.5]). Low and intermediate risk patients (d'Amico classification) were less prone to biochemical recurrence than high risk (81.05% (IC à 95% [64.1-90.5]) 5y-BRFS as opposed to 35.09% (IC à 95% [20.1-50.4]) respectively) (P<0.0001). As were patients with a Gleason score≤7 75.35% (IC à 95% [59.7-85.6]) compared to 32.31% (IC à 95% [16.5-49.2]) for higher Gleason (>7 scores [P=0.0002]). A Gleason score>7 (OR=6.9; P=0.002), PSA nadir>1ng/mL (OR=25.8; P=0.0026) and peri-urethral invasion (OR=35.8; P<0.001) were major risk factors for local recurrence in univariate analysis. In multivariate analysis, only PSA nadir>1ng/mL (OR=12.9; P=0.042) and peri-urethral invasion (OR=21.6; P=0.0003) remain major risk factors for recurrence. About 13 (16.46%) patients were incontinent of which 3 (3.79%) required placement of an artificial urinary sphincter. Erectile dysfunction was present in 66 (83.5%) patients. Recto-urethral fistula was uncommon in 1 patient (1.27%). CONCLUSION: Salvage cryotherapy after failure of external radiotherapy and brachytherapy is a reliable and reproducible technique with promising oncological and functional results. Study of prognostic factors will help better select eligible patients in the future. LEVEL OF EVIDENCE: 4.

[Salvage cryotherapy for recurrent prostate cancer after radiotherapy failure: principles, indications, patient selection, oncological results and morbidity]. / Cryothérapie de rattrapage après radiothérapie prostatique : principes, indications, sélection des patients, résultats oncologiques et morbidité

Potentially curative salvage options for biochemical failure after primary prostatic radiotherapy include salvage radical prostatectomy, brachytherapy, high-intensity focused ultrasound and cryotherapy. Salvage cryoablation for recurrent prostate cancer after irradiation failure is currently a well-established therapeutic option, since technical improvements have permitted better oncologic outcomes and lower complications rates over the years. This article reviews surgical technique, oncologic and functional outcomes, as well as morbidity and complications of salvage cryotherapy for local recurrence after external beam radiotherapy or brachytherapy for prostate cancer.

[CCAFU Recommendations 2013: Renal cancer]. / Recommandations en onco-urologie 2013 du CCAFU: Cancer du rein.

INTRODUCTION: The renal sub Committee of the CCAFU established guidelines for diagnosis, treatment, evaluation and standard of care for renal cell carcinoma. METHODS: 2010 Guidelines were updated based on systematic literature search performed by the sub-Committee in Medline and PubMed databases to evaluate references, levels of evidence and grade of recommendation. RESULTS: Multiphasic CT is the standard imaging technique for renal tumors diagnosis. Percutaneous renal biopsies are increasingly important for the management of localized RCC. Partial Nephrectomy is the first option when technically feasible for cT1 tumours. Open surgery remains the standard approach for locally advanced RCCs. New drugs are available for the treatment of metastatic RCC while the role of nephrectomy needs to be established by the Carmena trial. CONCLUSIONS: Conservative and mini-invasive therapies are increasingly important for the management of localized RCC. Therapeutic armamentarium continues to increase in mRCC.

[Active surveillance for prostate cancer: usefulness of endorectal MR at 1.5 Tesla with pelvic phased array coil in detecting significant tumors]. / Cancer de la prostate localisé: l'IRM endorectale à 1,5 Tesla améliore-t-elle la sélection des patients en vue d'une surveillance active?

PURPOSE: To describe and assess MRI signs of significant tumor in a series of patients who all underwent radical prostatectomy and also fulfilled criteria to choose active surveillance according to French "SurAcaP" protocol. PATIENTS AND METHODS: The clinical reports of 681 consecutive patients operated on for prostate cancer between 2002 and 2007 were reviewed retrospectively. All patients had endorectal MR (1.5 Tesla) with pelvic phased array coil. (1.5 T erMR PPA). Sixty-one patients (8.9%) fulfilled "SurAcaP" protocol criteria. Preoperative data (MR+core biopsy) were assessed by comparison to whole-mount step section pathology. RESULTS: 85.3% of the 61 patients entering SurAcaP protocol had significant tumor at pathology. (Non Organ Confined Disease (Non OCD)=8.2%, Gleason sum score>6=39.2%). A new exclusion criterion has been assessed: T3MRI±NPS>1 as a predictor tool of significant tumor. ("T3MRI±NPS>1"=Non OCD at MR±number of positive sextants involved in tumor at MR and/or Core Biopsy > to 1). Sensitivity, specificity, PPV, NPV of the criterion "T3MRI±NPS>1" in predicting significant tumor were, respectively: 77%, 33%, 86%, 20%. Adding this criterion to other criteria of the "SurAcaP" protocol could allow the exclusion of all Non OCD, and a decrease in Gleason sum Score>6 rates (20%). CONCLUSION: Endorectal MR at 1.5 Tesla with pelvic-phased array coil should be considered when selecting patients for active surveillance in the management of prostate cancer. A criterion based upon MR and core biopsy findings, called "T3MR±NSP>1" may represent an exclusion citeria due to its ability to predict significant tumor.

[Current role of lymph node dissection in renal cell carcinoma: review of the literature by the Oncology Committee of the French Association of Urology (CCAFU)]. / Place du curage ganglionnaire dans la prise en charge des cancers du rein : revue de la littérature par le sous-comité rein du Comité de cancérologie de l'Association française d'urologie (CCAFU-rein).

Nowadays, most of renal cancers are incidental tumors less than 4 cm. Prevalence of lymph node involvement is low and does not require a systematic lymphadenectomy as described by Robson in the 1960s. Radiologic progress and particularly CT scan describe with high precision lymph node involvement in the initial work-up. In renal cancer with a high risk of recurrence, lymphadenectomy has a pronostic interest and therapeutic role in rare situations where lymph node involvement is isolated. In metastatic patients, the role of cytoreductive nephrectomy has to be assessed.

[Retroperitoneal laparoscopic treatment of symptomatic caliceal diverticular calculi]. / Traitement par laparoscopie rétropéritonéale d'un amas lithiasique intradiverticulaire caliciel symptomatique.

Treatment of urinary calculi in caliceal diverticular is indicated when they are symptomatic. Minimally invasive techniques, in particularly laparoscopic approach, occupy an increasingly important place in the urological therapeutic armamentarium and have changed from an open surgical approach to endoscopic treatment for the management of symptomatic caliceal diverticular calculi. Herein, we report the case of a woman with symptomatic calculi in an upper caliceal diverticular managed by retroperitoneal laparoscopic approach.

[Surgical complications in kidney transplantation]. / Complications chirurgicales de la transplantation rénale.

Kidney transplantation has become the treatment of choice for patients with end stage renal disease since it offers an excellent quality of life. Moreover, the economic impact is considerable, particularly beyond the first year. Indeed, the annual cost of a successful renal transplantation is ten fold lower than haemodialysis. But surgical complications remain one of our main concerns. Surgical complications are various. They may be non-specific as haematomas, incision-induced hernias and wound infections. They may also be directly related to the procedure as vascular thrombosis and urinary fistula in the early postoperative period or arterial stenosis and ureteral obstruction in the late post-operative period. The accurate diagnosis and the appropriate management of these complications are the most important tasks for the surgical team. This review is based upon our experience in kidney transplantation and upon the medical published data.

[De novo tumours of renal transplants]. / Tumeurs de novo du transplant rénal.

Kidney cancer occurs rarely and late in renal transplants. The lack of grafts and the increasing age of the cadaver donors are likely to result in an increasing number of such cancers. To date, the treatment of choice is the transplant removal. Nevertheless partial nephrectomy may be discussed in selected cases. Ultrasonographic screening should allow detection of low volume tumours suitable for partial nephrectomy. Alternative techniques (radiofrequency, cryoablation) are to be assessed in such patients.

[Should double J catheter be systematically considered in renal transplantation?]. / Faut-il mettre une sonde double J de façon systématique lors d'une transplantation rénale?

Protection of urinary anastomoses using a ureteral catheter is a frequent option in urology but such use in a systematic manner remains debated in renal transplantation. Some consider that systematic insertion of a double J sound decreases the incidence of ureteral complications (fistula and stenosis). Others who prefer a selective use in some situations with a related risk consider that the implementation of a double J catheter cannot compensate a technical defect. It is even responsible for specific complications (infections, incrustation, haemorrhages); it increases implantation costs and is useless in more than 90% of the cases. This article analyses the risks related to systematic implementation of a double J catheter in Lich-Gregoir ureterovesical anastomoses for renal transplantation, together with the related costs and the infectious risk. The benefits in terms of prevention of ureteral complications are evaluated.

Late ureteral stenosis following renal transplantation: risk factors and impact on patient and graft survival.

The aim of this retrospective study of a cohort of 1787 consecutive kidney transplantations was to analyze the risk factors associated with the occurrence of ureteral stenosis and the impact of ureteral stenosis on graft and patient survival. Between January 1990 and December 2002, 1787 renal transplantations were performed at our center. Only stenosis observed after the first month, were considered. Among the parameters studied were: donor age and serum creatinine before procurement; recipient age, cold ischemia time, delayed graft function (DGF), number of arteries and the presence of a double J stent. The follow-up parameters were the number and timing of acute rejection episodes, cytomegalovirus (CMV) infection, acute pyelonephritis, renal function and death. Ureteral stenosis occurred in 4.1% of patients and was correlated with donor age > 65 years (p = 0.001), kidneys with more than 2 arteries (p = 0.009) and DGF (p = 0.016). Ureteral stenosis did not affect 10-year patient and graft survival rates, which were respectively 90% and 64% for the stenosis group, 86% and 63% for the no-stenosis group (p = NS). These data suggest an important role for donor age, number of renal arteries and DGF for the occurrence of ureteral stenosis following renal transplantation.
