Prognostic significance of PI-RADS 5 lesions in patients treated by radical prostatectomy.

PURPOSE: To analyse the pathological features and survival of patients with a PI-RADS 5 lesion on pre-biopsy MRI. METHODS: We extracted from a European multicentre prospectively gathered database the data of patients with a PI-RADS 5 lesion on pre-biopsy MRI, diagnosed using both systematic and targeted biopsies and subsequently treated by radical prostatectomy. The Kaplan-Meier model was used to assess the biochemical-free survival of the whole cohort and univariable and multivariable Cox models were set up to study factors associated with survival. RESULTS: Between 2013 and 2019, 539 consecutive patients with a PI-RADS 5 lesion on pre-biopsy MRI were treated by radical prostatectomy and included in the analysis. Follow-up data were available for 448 patients. Radical prostatectomy and lymph node dissection specimens showed non-organ confined disease in 297/539 (55%), (including 2 patients with a locally staged pT2 lesion and lymph node involvement (LNI)). With a median follow-up of 25 months (12-39), the median biochemical recurrence-free survival was 54% at 2 years (95% CI 45-61) and 28% at 5 years (95% CI 18-39). Among the factors studied, MRI T stage [T3a vs T2 HR 3.57 (95%CI 1.78-7.16); T3b vs T2 HR 6.17 (95% CI 2.99-12.72)] and PSA density (HR 4.47 95% CI 1.55-12.89) were significantly associated with a higher risk of biochemical recurrence in multivariable analysis. CONCLUSION: Patients with a PI-RADS 5 lesion on pre-biopsy MRI have a high risk of early biochemical recurrence after radical prostatectomy. MRI T stage and PSA density can be used to improve patient selection and counselling.

The proportion of potential candidates for focal therapy in localized prostate cancer in a real-life cohort and their final pathologic results.

OBJECTIVES: To determine the proportion of patients who would have been eligible for focal therapy (FT) in a population of patients who underwent prostatectomies; additionally, to assess the risk of having underestimated disease on the surgical specimen by using consensus selection criteria. METHOD: We retrospectively analyzed data from 446 patients who underwent radical prostatectomy between 2016 and 2018. Patients suitable for FT had unifocal significant prostate cancer on MRI, as well as on pathological data from targeted and systematic biopsies. Inclusion criteria were defined by the 2014 consensus conference, PSA<15ng/mL, tumor stage T1c-T2a and Gleason score 3+3 or 3+4 on biopsies. Disease was considered to be underestimated on postoperative data in the presence of extraprostatic invasion, a high Gleason score (≥4+4) and significant multifocality defined by secondary foci of Gleason 6 (3+3)>5mm or Gleason 7 (3+4). RESULTS: In our cohort of 446 patients, 97 patients met the inclusion criteria, and 27 patients (27.8%) were eligible for focal therapy. Among the eligible patients, 4 patients (14.8%) had pT3, and no patient had significant multifocality or a Gleason score of 8 (4+4) on the surgical specimen. CONCLUSION: In the era of pre-biopsy MRI, there could be a significant proportion of patients who could benefit from focal therapy among patients currently undergoing radical prostatectomy. The 2014 consensus conference eligibility criteria could effectively predict the presence of extraprostatic invasion and safely select patients for FT.

[Surgical and interventional management of benign prostatic obstruction: Guidelines from the Committee for Male Voiding Disorders of the French Urology Association]. / Traitement chirurgical et interventionnel de l'obstruction sous-vésicale liée à une hyperplasie bénigne de prostate : revue systématique de la littérature et recommandations de bonne pratique clinique du Comité des Troubles Mictionnels de l'Homme.

OBJECTIVE: The aim of the Male Lower Urinary Tract Symptoms Committee (CTMH) of the French Urology Association was to propose an update of the guidelines for surgical and interventional management of benign prostatic obstruction (BPO). METHODS: All available data published on PubMed® between 2018 and 2020 were systematically searched and reviewed. All papers assessing surgical and interventional management of adult patients with benign prostatic obstruction (BPO) were included for analysis. After studies critical analysis, conclusions with level of evidence and French guidelines were elaborated in order to answer the predefined clinical questions. RESULTS/GUIDELINES: Offer a trans-uretral incision of the prostate to treat patients with moderate to severe lower urinary tract symptoms (LUTS) with a prostate volume<30cm3, without a middle lobe. TUIP increases the chances of preserving ejaculation. Propose mono- or bipolar trans-urethral resection of the prostate (TURP) to treat patients with moderate to severe LUTS with a prostate volume between 30 and 80cm3. Vaporization by Greenlight™ or by bipolar energy can be offered as an alternative to TURP. Offer a Greenlight™ laser vaporization to patients at risk of bleeding. Offer endoscopic prostate enucleation to surgically treat patients with moderate to severe LUTS as an alternative to TURP and open prostatectomy (OP). Minimally invasive prostatectomy is an alternative to OP in centers without access to adequate endoscopic procedures. Embolization of the prostatic arteries may be offered in the event of a contraindication or refusal of surgery for prostates with a volume>80cm3. Prostatic uretral lift is an alternative in patients interested in preserving their ejaculatory function and with a prostate volume<70cm3 without a middle lobe. Aquablation and Rezum™ are under evaluation and should be offered in research protocols. CONCLUSION: Major changes in surgical management of BPO have occurred and aim at reducing morbidity and improving quality of life of patients.

[Prostatic urethral lift using Urolift® system for benign prostatic hyperplasia: 7years experience]. / Pose d'implants Urolift® intra-prostatique pour hyperplasie bénigne de la prostate : résultats après 7 ans d'expérience.

INTRODUCTION: Urolift® system is a mini-invasive technique, proposed as an alternative treatment for classic surgery of benign prostatic hyperplasia (BPH). Our objective was to report the results of Urolift® system in our center after 7years experience. PATIENTS AND METHODS: Urolift® implants were proposed between February 2012 and March 2019 for patients presenting symptomatic BPH in our center, as an alternative for classic surgery. The efficacy was evaluated with questionnaires about lower urinary tract symptoms (IPSS) and its impact on quality of life (IPSS-QdV). Tolerance was evaluated with questionnaires about erectile (IIEF5) and ejaculatory function (MSHQ-EjD) and complication rate. Survival without additional treatment was assessed using Kaplan-Meier method. RESULTS: Forty patients were treated during this period, with a median follow-up of 32months [12-67]. Three months after the procedure, IPSS and IPSS-QdV were significantly improved (respectively 8 [4-11] vs 20 [17-24]; P<0.0001 and 2 [1-2] vs 5 [4-6]; P<0.0001). MSHQ-EjD and IIEF5 were not modified (respectively 13 [11-14] vs 12 [9-13]; P=0.69 and 21 [18-23] vs 21 [18-23]; P=0.13). Two patients (5%) experienced a urinary retention and needed a bladder catheter. No complication with a Clavien-Dindo score>2 were reported. Survival without additional treatment at 5years was 63%. CONCLUSION: Urolift® implants improved significantly the lower urinary tract symptoms in our population, with a good tolerance profile. More than 60% of the patients did not need an additional treatment after 5years of follow-up. LEVEL OF EVIDENCE: 3.

[TMPRSS2-Erg/AR-V7: Prognostic value of tests in urine and biopsy rince material in prostate cancer]. / TMPRSS2-Erg/AR-V7 : valeur diagnostique des tests urinaires et sur liquides biopsiques dans le cancer prostatique.

INTRODUCTION: Nowadays, diagnostic biomarker research is oriented on a genomic characterisation of prostate cancer (PCa). This study evaluated diagnostic values of TMPRSS2-Erg fusion transcripts expression (TE) and androgen receptor variant 7 (AR-V7) on urine (tU) and biopsic rince material (tLRB) samples. MATERIALS AND METHODS: TE and AR-V7 have been tested by RT-PCR and RT-qPCR on urine and biopsies' rince liquid on 372 patients referred for prostate biopsies. RESULTS: Two hundred thirty-three patients (62%) were diagnosed with PCa. tU.AR-V7 was positive for 15 healthy patients (28%) and 30 patients diagnosed with PCa (37%). tLRB.AR-V7 was positive for 66 patients (42%) diagnosed with PCa. Concerning TE for patients diagnosed with PCa, tU was positive for 59 patients (54%) and tLRB for 132 (55%). TE and TE/AR-V7 combination were significantly associated with PCa (P<0.001), as tLRB.AR-V7 (P<0.001). Sensitivity and specificity for TE/AR-V7 combination for PCa were respectively: tU.TE/AR-V7 67% and 70%, tLRB.TE/AR-V7 68.8% and 71%, and, tUtLRB.TE/AR-V7 83% and 60%. There was no benefit for AR-V7 and TE association versus TE alone when comparing AUC. CONCLUSION: AR-V7 is not specific of PCa because of detection on healthy patients. This study did not managed to show a sufficient diagnostic value for TE/AR-V7 combination on urine and biospic rince material tests. LEVEL OF EVIDENCE: 3.

[Optical coherence tomography of bladder resection specimen]. / Tomographie par densité optique des pièces de résection des tumeurs de vessie.

INTRODUCTION: The diagnosis of bladder urothelial tumors is based on bladder resection and histological analysis of the specimen. The time to obtain the results of the histological analysis increases the treatment delay. Furthermore, the lack of muscle on the specimen forces the surgeon to practice on other procedure. Full field optical coherence tomography (FFOCT) is a recent imaging technique to analyze tissue. The aim of our study was to evaluate the feasibility and diagnostic accuracy of FFOCT to detect muscle and tumor in bladder resection specimen. PATIENTS AND METHODS: We analyzed with the FFOCT technique bladder resection specimen of 24 consecutives patients. Three readers did the blind analyze of the images, looking for the presence of muscle and tumor on each specimen. Their results were compared with histological analysis to calculate diagnostic accuracy for each reader. RESULTS: Mean sensibilities for the detection of muscle and tumor were respectively 75% and 81%. Mean specificities for the detection of muscle and tumor were respectively 78.3% and 55.3%. CONCLUSIONS: Our results suggest that the FFOCT is feasible to analyze bladder resection specimen. Sensibilities and specificities calculated are encouraging for the detection of muscle and tumor. The accuracy of this detection and early-staging tool should be validated by larger studies. LEVEL OF EVIDENCE: 3.

[Multidisciplinary and systematic preoperatory-assessment in geriatric urologic oncology surgery: Feasibility and results]. / Évaluation pluridisciplinaire préopératoire systématique en chirurgie cancérologique urologique gériatrique : faisabilité et résultats.

INTRODUCTION: The incidence of cancer increases with age, especially for urological cancers. The frailty of the elderly persons may expose them to more postoperative complications resulting in prolonged hospitalization, increased morbidity or even increased mortality, and delayed or impossible return to normal life. In such cases, the benefit of surgery and therefore its realization can be questioned. PATIENTS AND METHOD: This article reports the experience of a pre-operative risk assessment in a population of elderly patients treated for urologic cancer. This retrospective study aims to report the feasibility and the main results of this systematic preoperative multi-professional evaluation. RESULTS: Between April 2016 and February 2017, 31 elderly patients were evaluated. The evaluation revealed: moderate to severe malnutrition in 59 % of cases, a patient judged from a geriatric point of view fit, intermediate or fragile in respectively 25 %, 35 % and 40 % of cases. This evaluation led to propose a modification of an element of care for 66 % of patients and to propose therapeutic abstention for only 3 patients. CONCLUSION: An evaluation whose purpose is to adapt to the physiological age of patients and their overall state of health, surgical treatment and postoperative management is feasible and seems to help unmask elements of fragility usually not detected.

Study of the intra-prostatic arterial anatomy and implications for arterial embolization of benign prostatic hyperplasia.

INTRODUCTION: Prostatic arterial embolization (PAE) is an experimental therapy for benign prostatic hyperplasia. Its feasibility is based on the knowledge of the pelvic arterial anatomy, and more specifically the prostate. The aim of this study was to describe the prostatic arterial supply: origins, distribution and variability. MATERIAL AND METHODS: We reviewed retrospectively, with two radiologists, 40 arteriographies of patients who underwent PAE in our center. With these observations of 80 hemipelvics, we described the number of prostatic arteries, their origins, their distributions and eventually their anastomoses with other pelvic arteries. RESULTS: There was one prostatic artery in 70% of the cases. It came from a common trunk for the prostate and the bladder in 55% of the cases, from the obturator artery in 17.5% of the cases, from the pudendal artery in 25% of the cases, from the intern iliac artery in 1% of the cases, and from the superior gluteal artery in 1% of the cases. The prostatic artery splitted in two branches (medial and lateral), with no anastomoses in 37% of the cases. Anastomoses with penile and rectal arteries were observed in 29% of the cases. CONCLUSIONS: For our 40 patients, we observed many variations of arterial prostatic anatomy. We proposed a classification in order to increase security and efficacy of PAE, and it should be validated with more patients. LEVEL OF EVIDENCE: 2.

The HIV-1 viral synapse signals human foreskin keratinocytes to secrete thymic stromal lymphopoietin facilitating HIV-1 foreskin entry.

The complexity of signal transduction resulting from the contact of human immunodeficiency virus type 1 (HIV-1)-infected cells and mucosal cells has hampered our comprehension of HIV-1 mucosal entry. Such process is driven efficiently only by viral synapse contacts, whereas cell-free HIV-1 remains poorly infectious. Using CD4+ T-cells expressing only HIV-1 envelope inoculated on human adult foreskin tissues, we designed methodologies to identify the signals transduced in foreskin keratinocytes following HIV-1-envelope-dependent viral synapse formation. We find that the viral synapse activates the MyD88-independent TLR-4-nuclear factor (NfκB) signaling pathway in keratinocytes and the subsequent secretion of cytokines including thymic stromal lymphopoietin (TSLP), a cytokine linking innate and T-helper type 2-adaptive immune responses. Moreover, the viral synapse upregulates the non-coding microRNA miR-375, known to control TSLP, and transfection of keratinocytes with anti-miR-375 blocks significantly TSLP secretion. Thus, the secretion of TSLP by keratinocytes is induced by the viral synapse in a miR-375 controlled manner. At the tissue level, these signals translate into the epidermal redistribution of Langerhans cells and formation of conjugates with T-cells, recapitulating the initial events observed in human foreskin infection by HIV-1. These results open new possibilities for designing strategies to block mucosal HIV-1 transmission, the major pathway by which HIV-1 spreads worldwide.

[Pathological findings of visible and non-visible tumors on multiparametric magnetic resonance imaging (MRI) prior to radical prostatectomy]. / Caractéristiques anatomopathologiques des tumeurs apparentes et non apparentes en IRM multiparamétrique de la prostate avant prostatectomie totale.

INTRODUCTION: As urologists are questioned about the overtreatment of localized prostate cancer, multiparametric MRI can diagnose significant prostate cancer thanks to targeted biopsies. However, some tumors cannot be detected by MRI. What are the pathological characteristics of those tumors? MATERIALS AND METHODS: We have selected 144 consecutive patients treated with radical prostatectomy for clinically localized prostate cancer diagnosed on systematic and targeted biopsies (Koelis®) according to multiparametric MRI findings. On MRI, each suspicious area was graded according to the PI-RADS score v1.0. On radical prostatectomy specimen, tumor foci with a Gleason score greater than 3+3 and/or a tumor volume greater than 0,5cm3 were considered significant. The grade-four tumoral volume was calculated by multiplying the tumoral volume by grade 4 tumoral percentage. RESULTS: Two hundred and seventy seven tumors were identified. A hundred and thirty nine were non-visible on MRI. They had a significantly lower volume (0.15cm3 versus 1.45cm3, P<0.0001) and a Gleason score significantly lower (P<0.0001) than apparent tumors. 17.3% of non-apparent tumors were significant. Moreover, the grade-four tumoral volume of significant non-apparent tumors was significantly lower than that of significant apparent tumors (0.11cm3 versus 0.66cm3, P<0.0001). CONCLUSION: Non-apparent prostate tumors on multiparametric MRI have a Gleason score, a tumor volume - and consequently - a grade 4 tumor volume significantly lower than apparent tumors.

[Serious and unexpected complications of benign prostatic obstruction surgery: Results of the LUTS Committee survey from urologists of the French Urological Association]. / Complications graves et inattendues de la chirurgie de l'hyperplasie bénigne de prostate : résultats de l'enquête du CTMH auprès des urologues de l'AFU.

PURPOSE: Rare and severe complications of benign prostatic hyperplasia (BPH) surgery are poorly documented in the literature. Our purpose was to make an inventory of severe and unexpected complications of BPH faced by urologists of the French Association of Urology (AFU). MATERIAL AND METHODS: A declarative 13-question survey was sent by e-mail 2 months before the 108th French Congress of Urology to the urologist's members of the AFU. Complications were split in complications due to material and complications directly related to the surgery. RESULTS: Overall, 216 (16.2%) urologists surveyed but only 85 forms were usable. Complications related to the material was divided into: excessive temperature of the serum irrigation leading to urethral and bladder burns (n=5), material default leading to interruption of the procedure (n=1) or incomplete hemostasis (n=2) and endoscope rupture (n=1). Peroperative complications related to surgery were divided into surgical complications: haemorrhage (n=7), urethral wounds (n=6), perforation and/or explosion (n=16), rectal wounds (n=11), obstructive renal failure (n=1); and medical complications: TURP syndrome (n=2), cardiovascular (n=5) and septic shock (n=6). CONCLUSION: This is the first French declarative study having allowed the identification of severe and unexpected complications of BPH surgery. The recorded occurred complications were very eclectic and secondary to all types of techniques used.

[Are the UroLift(®) implants an alternative for the treatment of benign prostatic hyperplasia? Short-term results and predictive factors of failure]. / La pose d'implants intra-prostatiques UroLift(®) est-elle une alternative chez les patients ayant une hyperplasie bénigne de la prostate ? Résultats initiaux et facteurs prédictifs d'échec.

OBJECTIVE: To report the results of UroLift(®) implants after a 2-year experience in the technique. PATIENTS AND METHODS: The procedure was proposed between February 2012 and April 2014 in patients with symptomatic benign prostatic hyperplasia, as an alternative to standard endoscopic ablation techniques. Evaluation of BPH related symptoms relied on the IPSS and IPSS-QoL self-questionnaires, as well as on maximum uroflow (Qmax). Evaluation of erectile and ejaculatory functions relied on the IIEF5 and MSHQ-EjD self-questionnaires, respectively. RESULTS: A total of 23 patients were treated during this period. Median age was 66 years [53-78]. Median prostate volume was 38mL [20-80]. Preoperative IPSS and IPSS-QoL were 20 [9-29] and 5 [3-6], respectively. No severe adverse event was observed postoperatively. Median follow-up was 14 [5-31] months. At the end of follow-up, 19 (83%) patients reported sustained symptomatic improvement without any additional treatment. Median IPSS and IPSS-QoL were improved significantly (11 [1-27] and 2 [0-6], P<0.0001), with however no significant improvement in Qmax. Four patients needed additional treatment during the first postoperative year. Among them, 3 had a prostate volume>60mL. No patient reported retrograde ejaculation or worsened erectile function. CONCLUSIONS: UroLift(®) implants allowed symptomatic improvement in more than 80% of the patients after 1-year follow-up. A high prostate volume may potentially be predictive of symptomatic failure. LEVEL OF PROOF: 5.

[Guide dedicated to general practitioner for the management of lower urinary tract symptoms related to benign prostatic hyperplasia]. / Guide de prise en charge en médecine générale des symptômes du bas appareil urinaire de l'homme liés à une hyperplasie bénigne de la prostate.

OBJECTIVE: To establish a guide dedicated to general practitioner for the diagnosis, the follow-up, and the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH). METHOD: Guidelines already published for urologists were modified to make them relevant for general practitioners. The role of specialist's referral was defined. The whole content of the document was submitted to the formal consensus process in which urologists and general medicine teachers were involved. RESULTS: Initial assessment has several aims: making sure that LUTS are related to BPH, assessing bother related to LUTS, and checking for a possible complication. Initial assessment should include: medical history, physical examination with digital rectal examination, and urinalysis. Some other explorations such as frequency volume chart, serum PSA or creatinine, and ultrasonography of the urinary tract were found optional, meaning they are necessary only in specific situations. Referring to urologist is justified when LUTS might not be related to BPH (particularly when urgencies are predominant), or when a severe bladder outlet obstruction is suspected (severe symptoms, palpable bladder, post-voiding residual volume>100ml), or when a complication is assessed. Follow-up without treatment is justified for patients with no bothersome symptoms related to not complicated BPH. Several drugs are available for the treatment of bothersome symptoms related to BPH. Alpha-blockers and plants extracts might be offered as monotherapy. Five alpha reductase inhibitors might be offered to patients with LUTS related to a significant prostate hypertrophy (>40 ml) ; they might be given for a minimum duration of one year, alone or in association with alpha-blocker. The association of antimuscarinic and alpha-blocker might be used in patients with persistent storage LUTS in spite of alpha-blocker treatment. Phosphodiesterase 5 inhibitors might be offered to patients with erectile dysfunction associated with LUTS related to BPH. In case of complicated BPH, or when medical treatment is not efficacious or not tolerated, a surgical option should be discussed. CONCLUSION: The male lower urinary tract symptom committee of the French Urological Association and general practitioner present the first guide for the management of LUTS related to BPH dedicated to general practitioner. LEVEL OF EVIDENCE: 5.

Prostate cancer: review in 2014.

Recent advances need to be highlighted in the management of both localized and metastatic prostate cancer. New early detection and molecular characterization tools are being developed to improve differentiation of their progression profiles and reduce "overdetection" and "overtreatment" of clinically "insignificant" cancers. In addition, the development of multi-parametric MR has improved the characterization of localized cancer and introduced the new concept of focal treatment. Finally, several treatments for metastatic cancer which is resistant to castration have recently increased the therapeutic armamentarium.

[Full field optical coherence tomography of prostate biopsies: a step towards pre-histological diagnosis?]. / Tomographie par cohérence optique plein champ des biopsies de la prostate: un pas vers le diagnostic pré-histologique?

OBJECTIVES: To evaluate the value of full field optical coherence tomography (FFOCT) for cancer detection on prostate biopsies PATIENTS AND METHODS: Eight consecutive patients who underwent prostate biopsies for an elevated PSA or suspicious DRE findings were included in the study. For each patient, one to three biopsy cores were imaged with FFOCT immediately after sampling. Images obtained were analyzed by a pathologist blinded to the pathological results, and classified into three categories: non-cancerous tissue, suspicion of malignancy and prostate carcinoma. A pathological correlation analysis was further performed. RESULTS: Sixteen biopsy cores were analyzed. The median FFOCT procedure time was of 4 (3-5) minutes. No artifact was noted in subsequent pathological analysis. Six cores were involved with cancer and eight cores showed no evidence of cancer. On two cores, diagnosis was uncertain, and immuno-histochemical analysis confirmed cancer involvement in one of them. The agreement rate between standard histological analysis and FFOCT evaluation was of 81% (13/16). The three cases of disagreement were due to one false positive and two false negatives of FFOCT analysis. CONCLUSIONS: FFOCT of prostate biopsy cores seemed to be feasible and to allow concordant results with those of pathological analysis in the majority of the cases.
