[Early detection of prostate cancer: Towards a new paradigm?] / Détection précoce du cancer de la prostate : vers un nouveau paradigme ?

Prostate cancer (PCa) is a public health issue. The diagnostic strategy for PCa is well codified and assessed by digital rectal examination, PSA testing and multiparametric MRI, which may or may not lead to prostate biopsies. The formal benefit of organized PCa screening, studied more than 10 years ago at an international scale and for all incomers, is not demonstrated. However, diagnostic and therapeutic modalities have evolved since the pivotal studies. The contribution of MRI and targeted biopsies, the widespread use of active surveillance for unsignificant PCa, the improvement of surgical techniques and radiotherapy… have allowed a better selection of patients and strengthened the interest for an individualized approach, reducing the risk of overtreatment. Aiming to enhance coverage and access to screening for the population, the European Commission recently promoted the evaluation of an organized PCa screening strategy, including MRI. The lack of screening programs has become detrimental to the population and must shift towards an early detection policy adapted to the risk of each individual.

Mid-term oncologic outcomes of radical prostatectomy in lymph node metastatic prostate cancer patients.

OBJECTIVES: Lymph node invasion (LNI) has been reported in 10-15% of pelvic lymph node dissection during radical prostatectomy (RP). The objective of this study was to describe the mid-term oncological outcomes in prostate cancer (PCa) patients with metastatic lymph node. METHODS: We conducted a retrospective study at two French referral centers including consecutive cN0 PCa patients who underwent RP and extended pelvic lymph node dissection and had lymph node metastases on final pathological analysis (pN1) between January 2000 and May 2020. Follow-up was per institution, which generally included a PSA level measurement every 3 to 12 months for 5 years and annually thereafter. RESULTS: A total of 123 patients were included: two (1.6%) low-risk, 64 (52%) intermediate-risk and 57 (46.4%) high-risk PCa according to the D'Amico risk classification. The median number of nodes removed and metastatic nodes per patient was 15 (IQR 11-22) and 1 (IQR 1-2), respectively. Adverse pathological features, i.e., ≥pT3a stage, ISUP grade ≥3, and positive surgical margins were reported in 113 (91.9%), 103 (83.7%), and 73 (59%) of cases, respectively. Postoperative treatment was administered in 104 patients, including radiotherapy alone (n=6), androgen deprivation therapy alone (n=27) or combination with androgen deprivation therapy and radiotherapy (n=71). The mean follow-up was 42.7 months. The estimated 3-year biochemical-free survival, clinical recurrence-free survival, and cancer-specific survival was 66% and 85% and 98.8%, respectively. In Cox regression analysis, the number of metastatic nodes was associated with clinical recurrence (P=0.04) and a persistently elevated PSA with biochemical recurrence (P<0.001). CONCLUSION: The management of lymph node metastatic PCa patients is challenging. Risk stratification of node-positive patients, based on postoperative PSA levels and pathologic features being identified, should help physicians determine which patient would best benefit from multimodal treatment.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Diagnosis and management of localised disease.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the diagnosis and management of prostate cancer (PC). METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the diagnosis and therapeutic management of localised PC, while evaluating the references and their levels of evidence. RESULTS: The recommendations specify the genetics, epidemiology and means of diagnosing prostate cancer, as well as the notions of screening and early detection. MRI, the gold standard imaging examination for localised cancer, is recommended before prostate biopsies are performed. The transperineal approach reduces the risks of infection. The therapeutic methods are described and recommended according to the clinical context. Active surveillance is the gold standard of treatment for tumours with a low risk for progression. Early salvage radiotherapy is recommended in case of biochemical recurrence after radical prostatectomy. Imaging, particularly molecular imaging, helps to guide the decision-making in the event of biochemical recurrence after local treatment, but should not delay early salvage radiotherapy in the event of biological recurrence after radical prostatectomy. CONCLUSION: This update of the French recommendations should help to improve the management of patients with PC.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Management of metastatic disease and castration resistance.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the management of prostate cancer. METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the elements of therapeutic management of metastatic and castration-resistant prostate cancer (PC), while evaluating the references and their levels of evidence. RESULTS: Androgen deprivation therapy (ADT) remains the standard treatment for metastatic prostate cancer. ADT intensification is now a standard of care in the management of metastatic prostate cancer. This intensification is discussed in relation to the patient and the characteristics of the disease. For all metastatic hormone-sensitive PC (synchronous and metachronous), the overall survival benefit associated with good tolerability makes the combination of ADT and novel hormonal agents (NHA) a standard. For patients with high-volume/high-risk de novo metastatic disease, treatment with docetaxel in addition to ADT + NHA can be discussed for eligible patients. In patients with castration-resistant prostate cancer (CRPC), the contribution of new therapies that have become available in recent years, as well as the advent of precision medicine, help to improve the control of tumour progression and survival, and highlight the value of testing for alterations in DNA repair genes within the tumour tissue or constitutionally. CONCLUSION: This update of the French recommendations should help to improve the management of patients with prostate cancer.

[Recent advances in the management of localized high-risk prostate cancer: An update by the Prostate Cancer Committee of the French Association of Urology]. / Avancées récentes dans la prise en charge du cancer de la prostate localisé à haut risque : mise au point par le Comité Prostate de l'Association française d'urologie.

INTRODUCTION: The risk of recurrence is increased in localized high-risk prostate cancer (PCa). The implementation of an appropriate diagnostic and therapeutic strategy is essential. The objective of this update by the Prostate Committee of the French Association of Urology was to report the most recent data in the management of localized high-risk PCa. MATERIAL AND METHODS: This update is based on the data available in the literature on localized high-risk PCa. A PubMed search and narrative review of the recent data were performed in March 2022. RESULTS: Compared with conventional imaging, PET-PSMA is more effective for the diagnosis of lymph nodes and distant metastases. Two recent randomized clinical trials have failed to prove the oncologic benefit of extended pelvic lymph node dissection during radical prostatectomy (RP). Postoperatively, early salvage radiotherapy is the standard of care, with adjuvant radiotherapy becoming an option in case of unfavorable pathological criteria (ISUP 4-5, pT3±positive margins) in young patients. Although promising, perioperative systemic therapies (chemotherapy, second-generation hormonotherapy) cannot be recommended at this time when the patient is treated by RP. Regarding radiotherapy, prophylactic lymph node irradiation during prostatic irradiation was associated with improved biochemical and metastasis-free survival in a recent randomized trial but it is still controversial. Since the publication of the results of the STAMPEDE trial, the addition of abiraterone acetate to radiation-hormone therapy should be considered the new standard of care for patients with localized (very) high-risk PCa, according to the inclusion criteria of the study. CONCLUSION: The most recent data of the literature regarding the management of high-risk localized PCa redefine the diagnostic performance of molecular imaging, the timing of postoperative radiotherapy, the oncologic benefit of pelvic lymph node treatment, and the intensification of systemic therapies.

Renal tumor biopsy does not increase the risk of surgical complications of minimally invasive partial nephrectomy.

BACKGROUND: For patients with cT1 renal lesions, Partial Nephrectomy (PN) is the gold standard treatment. However, 20% of small renal masses are benign, situation in which the PN is an overtreatment. The percutaneous Renal Tumor Biopsy (RTB) may lower the risk of overtreatment as there is a 90% concordance rate on histotype between the RTB and the final pathology. It has been suggested that the RTB could increase the difficulty of the PN and increase the risk of surgical complications. OBJECTIVE: To compare surgical outcomes and complications of PN with or without previous RTB. DESIGN, SETTING, AND PARTICIPANTS: monocentric retrospective review of patients who underwent laparoscopic or robotic-assisted PN between January 2012 and December 2019. MEASUREMENTS: perioperative complications were recorded using Clavien-Dindo classification, peroperative data included operative time, clamping time and blood loss, and histological outcomes of RTB and PN. RESULTS AND LIMITATIONS: In total, 163 patients were included in our study. There were significantly less benign lesions in PN with prior RTB: 7% (4/56) vs. 20% (22/107) without prior RTB (P=0.03). There were no significant differences regarding Clavien-Dindo>2 perioperative complications with respectively 7% (4/56) vs. 10% (11/107) (P=0.57). Same goes for peroperative data such as duration of surgery (P=0.81), warm ischemia (P=0.07) and blood loss (P=0.13). CONCLUSIONS: RTB does not increase the risk of surgical complications of PN and may reduce the risk of small renal masses overtreatment.

[DNA repair gene alterations testing in prostate cancer : A practical update by the prostate cancer committee of the french association of urology]. / Recherche d'altérations des gènes de réparation de l'ADN dans le cancer de la prostate : mise au point pratique du Comité de cancérologie de l'association française d'urologie.

INTRODUCTION: Current therapeutic developments in prostate cancer (PCa) tend to increasingly personalize the treatment strategy, in particular as a function of tumor genomics. Recently, poly ADP-ribose polymerase (PARPi) inhibitors have shown their efficacy at the stage of castration resistance, in case of alteration of DNA repair genes in tumor tissue. MATERIAL AND METHODS: A narrative review was carried out on recent data in the literature since 2000. A consensus among the members of the Committee was obtained in order to synthesize the current data, with a particular focus on the practical considerations regarding indications and developments of molecular testing circuits concerning DNA repair genes, for theranostics purpose. RESULTS: The establishment of an efficient molecular testing network is based on the multidisciplinary organization of the various actors and the coordination of all material resources. Its goal is the routine search for somatic mutations (in tumor tissue) of BRCA1/2 genes in patients who may benefit from PARPi. The current indications are for BRCA1 or 2 mutated castration-resistant metastatic PCa after next-generation hormone therapy failure. The demand for molecular testing must be decided in the tumor board, giving priority to archived tissue less than 10 years old. In case of unsuccess, biopsies of the primary or metastases, or even analysis of circulating tumor DNA, may be necessary. Any demand for a genetic test on tumor tissue must be accompanied by detailed information for the patient on the possible familial consequences, in case of associated germline mutation. CONCLUSION: This article aims to guide the practical implementation of molecular testing circuits for DNA repair genes alterations, in order to guide the therapeutic management of patients with advanced PCa.

[Rectourethral fistula treatment using the modified York Mason technique: Failure factors assessment]. / Cure de fistule recto-urétrale par la technique modifiée de York Mason : évaluation des facteurs d'échec.

OBJECTIVES: To assess surgical outcomes and failure factors in the management of rectourethral fistulas treated surgically with the modified York Mason technique based on our center's 25 years of experience. METHODS: From 1997 to 2021, in a single center study, a total of 35 consecutive patients, underwent rectourethral fistula cure, using the modified York Mason technique. Preoperative patient data, surgical outcomes and failure factors were assessed. RESULTS: Of the 35 patients, 28 were successfully managed without the need of further intervention (80%). Median age was 67 years (IQR 62-72) and median follow-up time was 71 months (IQR 30-123). There was no significant difference between the patients that had recurrence or not after the first York Mason. CONCLUSIONS: The modified York Mason technique offers a high success rate for the cure of iatrogenic rectourethral fistulas. No predictive factor of failure, after a first cure of recto-uretral fistula by modified York-Mason technique was reported. LEVEL OF EVIDENCE: 3.

Narrative review of PET/CT performances at biochemical recurrence in prostate cancer after radical prostatectomy and impact on patient disease management: Revue narrative à propos des performances de la TEP/TDM en cas de récidive biochimique après prostatectomie radicale dans le cancer de la prostate et impact sur la prise en charge des patients.

Patients treated by radical prostatectomy (RP) for localized prostate cancer (PCa) may experience biochemical recurrence (BCR) in approximately 30% of cases. Recently, advances in imaging modalities and in particular Positron-Emission Tomography with computed tomography (PET/CT) imaging allow for better detection and characterization of lesions outside the prostatic bed at recurrence. Thus, treatment at BCR can be significantly improved by a tailored strategy based on new generation imaging. A more precise and accurate staging of the disease at recurrence paves the way to more appropriate treatment, potentially translating into better survival outcomes of these patients. This review therefore highlights the interest of PET/CT at the time of BCR, its superiority over standard imaging in terms of staging, and its impact on guiding the different therapeutic possibilities depending on the site, number, and volumes of recurrence. Indeed, we will discuss below about different strategies and their indications: salvage radiotherapy of the prostate bed, systemic therapies, stereotactic body radiotherapy and others therapeutical strategies. The various innovative approaches based on PET/CT implementation are partly underway within protocol trials to prove their benefits on clinically meaningful endpoints. © 2022 Elsevier Masson SAS.

How PET-CT is Changing the Management of Non-metastatic Castration-resistant Prostate Cancer?: Comment la TEP-TDM Peut Modifier la Prise en Charge du Cancer de la Prostate Non Métastatique Résistant à la Castration ?

INTRODUCTION: The aim of this narrative review conducted by the Prostate Cancer Committee of the French Association of Urology (CC-AFU) was to provide an update on the current evidence for the impact of PET/CT in the management of men with non-metastatic castration-resistant prostate cancer (nmCRPC). MATERIAL AND METHODS: This review is based on data available in the literature on PET/CT imaging for staging nmCRPC patients. A PubMed search and narrative review of the data were performed in March 2022. Only articles in French or English were considered. RESULTS: Current guidelines recommend bone scan and CT scan as standard imaging modalities for staging and follow-up of patients with nmCRPC. Nearly one-third of asymptomatic patients with presumed nmCRPC ultimately have metastatic disease on conventional imaging. Increasing reports have shown that conventional imaging has limited accuracy in detecting metastatic disease in nmCRPC patients, leading to the development of next-generation imaging techniques. In a retrospective study, 18F-choline PET/CT detected distant metastases in 27/58 high-risk nmCRPC patients with prior negative conventional imaging. The implementation of radiolabeled ligands of the prostate-specific membrane antigen (PSMA) PET/CT in staging strategy has resulted in metastasis detection in 45% to 98% of patients with presumptive nmCRPC on conventional imaging. Such an early diagnosis of metastatic CRPC may allow patients to be referred for metastasis-directed therapies (i.e. stereotactic body radiotherapy), aimed at prolonging the efficacy of systemic therapies and improving clinical outcomes. However, current data are not strong enough to recommend this strategy, which must be properly evaluated in clinical trials. Indeed, the use of molecular imaging may lead to inappropriate undertreatment if the second-generation androgen receptor inhibitors (darolutamide, enzalutamide, apalutamide), which prolong life, are not used in the subgroup of patients with high PSA velocity (PSA doubling time <10 months). CONCLUSION: Implementation of PSMA-PET/CT in the staging strategy would result in a migration of disease stage to extra-pelvic, M1 disease in at least half of presumed nmCRPC patients. The unprecedented accuracy of PSMA-PET/CT may pave the way for a more personalized treatment strategy. However, no data yet support this strategy for all nmCRPC patients as no oncologic benefit of early detection of M1 disease or MDT has been demonstrated. © 2022 Elsevier Masson SAS.

Papel de la resonancia magnética multiparamétrica en la selección y el seguimiento de pacientes en vigilancia activa por cáncer de próstata. Revisión del grupo de Uro-Tecnología (ESUT) de la EAU / The role of multiparametric magnetic resonance imaging in the selection and follow-up of patients undergoing active surveillance for prostate cancer. An European Section of Uro-Technology (ESUT) review

Introducción: En los últimos años, la vigilancia activa (VA) ha ganado popularidad como una opción segura y razonable para los pacientes con cáncer de próstata de bajo riesgo clínicamente localizado.ObjetivoResumir la información más reciente sobre el uso de resonancia magnética multiparamétrica (RMmp) en el contexto de la vigilancia activa (VA) para el tratamiento del cáncer de próstata (CaP).Adquisición de la evidenciaSe realizó una búsqueda en la literatura en inglés mediante PubMed hasta febrero de 2020. Se seleccionaron los artículos originales, metaanálisis, y revisiones sistemáticas más relevantes.Síntesis de la evidenciaLa gran importancia de la RMmp de la próstata en el contexto del diagnóstico del CaP es su capacidad de detectar lesiones cancerosas de alto grado que pueden haber sido omitidas en biopsias sistemáticas. Diversos estudios han demostrado que la RMmp tiene un rendimiento superior con respecto a los modelos basados en la clínica para identificar aquellos candidatos que se beneficiarán más de la VA. Aunque hay poca información sobre la RMmp de próstata durante el seguimiento de hombres en VA, existe la posibilidad de que ésta pueda mejorar significativamente los programas de VA, gracias a una selección más rigurosa de candidatos óptimos, una identificación más precisa de la progresión de la enfermedad, y una reducción en el número de biopsias. El objetivo de la reevaluación de los pacientes sometidos a VA es encontrar el momento en el que cambiar la estrategia hacia el tratamiento activo sea lo más efectivo.ConclusiónEl valor de la RMmp ha sido reconocido debido a su alto valor predictivo negativo (VPN) en la detección de lesiones de mayor grado en pacientes con CaP de bajo riesgo. Un mejor sistema de detección en las pruebas de imagen y un diagnóstico más exacto con RMmp podría reducir las clasificaciones erróneas en el diagnóstico inicial y durante el seguimiento, reduciendo así el número de biopsias.

Introduction: In recent years, active surveillance (AS) has gained popularity as a safe and reasonable option for patients with low-risk, clinically localized prostate cancer.ObjectiveTo summarize the latest information regarding the use of mpMRI in the setting of active surveillance (AS) for the management of prostate cancer (PCa).Evidence acquisitionA PubMed-based, English literature search was conducted through February 2020. We selected the most relevant original articles, meta-analyses and systematic reviews that could provide important information.Evidence synthesisThe great importance of mpMRI of the prostate in the setting of PCa diagnosis is its ability to visualize primarily high-grade cancerous lesions potentially missed on systematic biopsies. In several studies, mpMRI has shown an improved performance over clinically based models for identifying candidates which will benefit the most from AS. Although data on prostate mpMRI during follow-up of men under AS is sparse, it holds the probability to improve significantly AS programs by a more precise selection of optimal candidates, a more accurate identification of disease progression and a reduction in number of biopsies. The goal of reassessment of patients undergoing AS is to find the most effective moment to change attitude to active treatment.ConclusionThe value of mpMRI has been recognized due to its high negative predictive value (NPV) for lesion upgrading in low-risk PCa patients. The improvement in imaging detection, and precise diagnosis with mpMRI could reduce misclassifications at initial diagnosis and during follow-up, reducing the number of biopsies. (AU)

La resonancia magnética como herramienta para el diagnóstico del cáncer de próstata: nuevas evidencias y posicionamiento de la ESUT (EAU Section of Uro-Technology) / Magnetic resonance as imaging diagnostic tool in prostate cancer: New evidences-The EAU Section of Uro-Technology position

El cáncer de próstata (CP) es la segunda causa principal de mortalidad por cáncer y la enfermedad diagnosticada con mayor frecuencia en la población masculina. El CP se manifiesta de diversas maneras: desde enfermedad indolente a altamente agresiva. A esto se debe la complejidad de su diagnóstico y de la elección del tratamiento adecuado. El enfoque utilizado actualmente, con pruebas de PSA y examen rectal digital seguido de biopsia transrectal ecodirigida, carece de sensibilidad y especificidad en la detección de CP y ofrece información limitada sobre la agresividad y el estadio del cáncer. La evidencia científica respalda el creciente uso de la resonancia magnética multiparamétrica como la herramienta de imagen más sensible y específica para la detección, la caracterización de lesiones y la estadificación del CP. El presente estudio hace una revisión actualizada del rol de la resonancia magnética en el diagnóstico de CP, revisando los últimos artículos publicados en PubMed

Prostate cancer (PCa) is the second leading cause of cancer-related mortality and the most frequently diagnosed male malignant disease among men. The manifestation of PCa ranges from indolent to highly aggressive disease and due to this high variation in PCa progression, the diagnosis and subsequent treatment planning can be challenging. The current diagnostic approach with PSA testing and digital rectal examination followed by transrectal ultrasound biopsies lack in both sensitivity and specificity in PCa detection and offers limited information about the aggressiveness and stage of the cancer. Scientific work supports the rapidly growing use of multiparametric magnetic resonance imaging as the most sensitive and specific imaging tool for detection, lesion characterization and staging of PCa. Therefore, we carried out an updated review of magnetic resonance imaging in the diagnostic PCa reviewing the latest papers published in PubMed

Prostatectomía inmediata versus demorada en pacientes que progresan a una enfermedad de mayor riesgo en vigilancia activa / Immediate versus delayed prostatectomy and the fate of patients who progress to a higher risk disease on active surveillance

Introducción: Se debaten los resultados oncológicos de la prostatectomía radical (PR) en pacientes que progresan en vigilancia activa (VA). Comparamos los resultados de los pacientes elegibles para VA sometidos a PR inmediatamente después del diagnóstico con aquellos que lo hacían después de un retraso o progresión de la enfermedad en VA. Métodos: Entre 2000 y 2014, 961 pacientes fueron elegibles para VA según los criterios de la EAU. Se comparó la PR a los 6 meses del diagnóstico (PRI) o más allá (PRT), PR sin VA (PRTa) y pacientes en VA que progresan a PR (PRTb). Se registró PSA inicial, características clínicas y de biopsia. Los resultados oncológicos incluyeron patología adversa (PA) en la muestra de PR y recurrencia bioquímica (RBQ). Se realizó un análisis de pares emparejados entre los pacientes con PRTb y GS7 sometidos a PR inmediata (GS7PRI). Resultados: PRI, PRT, PRTa y PRTb tuvieron 820 (85%), 141 (15%), 118 (12,24%) y 23 (2,7%) pacientes respectivamente. PRI, PRTa y PRTb se sometieron a PR a una mediana de 3, 9 y 19 meses después del diagnóstico, respectivamente. Las características basales fueron comparables. PRT vs. PRI tuvieron una mediana de tiempo más temprana (31 vs. 43 meses; p < 0,001) y una mayor tasa de progresión a RBQ (7,6 vs. 3,9%; p = 0,045). PRTb mostró RBQ más alta (19 frente a 5%; p = 0,021) con una mediana de tiempo más temprana a RBQ, en comparación con PRI y PRTa (p = 0,038). No hubo diferencias en las tasas de PA y RBQ, pero el tiempo hasta RBQ fue significativamente menor en PRTb (49 frente a 6 meses; p<0,001), en comparación con GS7PRI. Conclusiones: Los pacientes que progresaron en VA tuvieron los peores resultados oncológicos. PR para progresión de GS7 y par coincidente de pacientes con GS7 tuvieron resultados similares. Peores resultados oncológicos en los progresores de VA no pueden explicarse por una mera demora en PR

Introduction: Oncological outcomes of radical prostatectomy (RP) in patients progressing on active surveillance (AS) are debated. We compared outcomes of AS eligible patients undergoing RP immediately after diagnosis with those doing so after delay or disease progression on AS. Methods: Between 2000 and 2014, 961 patients were AS eligible as per EAU criteria. RP within 6 months of diagnosis (IRP) or beyond (DRP), RP without AS (DRPa) and AS patients progressing to RP (DRPb) were compared. Baseline PSA, clinical and biopsy characteristics were noted. Oncological outcomes included adverse pathology in RP specimen and biochemical recurrence (BCR). Matched pair analysis was done between DRPb and GS7 patients undergoing immediate RP (GS7IRP). Results: IRP, DRP, DRPa and DRPb had 820 (85%), 141 (15%), 118 (12.24%) and 23 (2.7%) patients respectively. IRP, DRPa and DRPb underwent RP at a median of 3, 9 and 19 months after diagnosis respectively. Baseline characteristics were comparable. DRP vs. IRP had earlier median time (31 vs. 43 months; p < 0.001) and higher rate of progression to BCR (7.6 vs. 3.9%; p = 0.045). DRPb showed higher BCR (19 vs. 5%; p = 0.021) with earlier median time to BCR, compared to IRP and DRPa (p = 0.038). There was no difference in adverse pathology and BCR rates, but time to BCR was significantly lesser in DRPb (49 vs. 6 months; p < 0.001), compared to GS7IRP. Conclusions: Patients progressing on AS had worst oncological outcomes. RP for GS7 progression and matched pair of GS7 patients had similar outcomes. Worse oncological outcomes in AS progressors cannot be explained by a mere delay in RP

Resultados oncológicos y características patológicas de la sobrestadificación de cT1 a carcinoma de células renales pT3a en comparación con los tumores pT3a de novo / Oncological outcomes and pathological characteristics of cT1 upstaging to pT3a renal cell carcinoma compared with de novo pT3a tumors

Introducción: La importancia de la sobrestadificación de tumores renales cT1 a pT3a no está clara. Evaluamos la incidencia de la sobrestadificación, identificamos factores predictivos y analizamos los resultados oncológicos de estos pacientes frente a aquellos que no sobrestadificaron. También comparamos los resultados oncológicos de la sobrestadificación de cT1 a pT3a con tumores renales pT3a de novo. Métodos: De una base de datos de 1.021 tumores renales con datos de seguimiento completos disponibles, 517 pacientes tenían cT1. Los pacientes que sobrestadificaron a pT3a se compararon con aquellos que no lo hicieron. Se analizaron los resultados de las características clínicas, perioperatorias, histopatológicas y oncológicas iniciales. Resultados: De 517 pacientes con cT1, 105 (20,3%) sobrestadificaron a pT3a y 412 (79,7%) no lo hicieron. La proporción de pacientes en cada grupo tratados mediante nefrectomía parcial y radical, el tamaño del tumor postoperatorio, la histología, el estado de los márgenes, y la afectación de ganglios linfáticos fueron similares. Entre los que sobrestadificaron, 9 pacientes (8,6%) desarrollaron la primera recurrencia en comparación con solo 3 (0,7%) en aquellos que no sobrestadificaron (p < 0,001). La mediana del tiempo hasta la recurrencia (57 frente a 107 meses; p < 0,001) fue menor en los tumores renales pT3a de novo. Conclusiones: La sobrestadificación patológica de cT1 a pT3a y la necrosis en la histopatología se asociaron con la recurrencia. La edad avanzada, el tabaquismo, la necrosis en la histopatología, la histología de células claras y grados más altos de Fuhrman contribuyeron a la sobrestadificación patológica de los tumores cT1. El CCR pT3a de novo tuvo una supervivencia peor cuando se comparó con los pacientes con cT1 que sobrestadificaron a CCR pT3a

Introduction: The significance of upstaging of cT1 renal tumors to pT3a is not clear. We evaluate the incidence of upstaging, identify predictors and analyze oncological outcomes of these patients versus those who did not upstage. We also compared the oncological outcomes of cT1 upstaging to pT3a with de novo pT3a renal tumors. Methods: From a database of 1021 renal tumors with complete available follow-up data, 517 patients had cT1. Patients upstaging to pT3a were compared to those who did not. Baseline clinical, perioperative, histopathologic features and oncological outcomes were analysed. Results: Out of 517 cT1 patients, 105 (20.3%) upstaged to pT3a and 412 (79.7%) did not. Proportion of patients in each group undergoing partial and radical nephrectomy, postoperative tumor size, histology, margin status and lymph node involvement were similar. Among upstaged, 9 patients (8.6%) developed first recurrence as compared to only 3 (0.7%) in those not upstaging (P < 0.001). The median time to recurrence (57 vs. 107 months; P < 0.001) was lesser in de novo pT3a renal tumors. Conclusions: Pathological upstaging from cT1 to pT3a and necrosis on histopathology were associated with recurrence. Advanced age, smoking, necrosis on histopathology, clear cell histology and higher Fuhrman grades contributed to pathological upstaging of cT1 tumors. De novo pT3a RCC had worse survival when compared to cT1 patients upstaging to pT3a RCC

DRP vs. IRP had earlier median time (31 vs. 43 months; p<.001) and higher rate of progression to BCR (7.6 vs. 3.9%;p=.045). DRPb showed higher BCR (19 vs. 5%;p=.021) with earlier median time to BCR, compared to IRP and DRPa (p=.038). There was no difference in adverse pathology and BCR rates, but time to BCR was significantly lesser in DRPb (49 vs. 6 months;p<.001), compared to GS7IRP. CONCLUSIONS: Patients progressing on AS had worst oncological outcomes. RP for GS7 progression and matched pair of GS7 patients had similar outcomes. Worse oncological outcomes in AS progressors cannot be explained by a mere delay in RP.

Oncological outcomes and pathological characteristics of cT1 upstaging to pT3a renal cell carcinoma compared with de novo pT3a tumors. / Resultados oncológicos y características patológicas de la sobrestadificación de cT1 a carcinoma de células renales pT3a en comparación con los tumores pT3a de novo.

INTRODUCTION: The significance of upstaging of cT1 renal tumors to pT3a is not clear. We evaluate the incidence of upstaging, identify predictors and analyze oncological outcomes of these patients versus those who did not upstage. We also compared the oncological outcomes of cT1 upstaging to pT3a with de novo pT3a renal tumors. METHODS: From a database of 1021 renal tumors with complete available follow-up data, 517 patients had cT1. Patients upstaging to pT3a were compared to those who did not. Baseline clinical, perioperative, histopathologic features and oncological outcomes were analysed. RESULTS: Out of 517 cT1 patients, 105 (20.3%) upstaged to pT3a and 412 (79.7%) did not. Proportion of patients in each group undergoing partial and radical nephrectomy, postoperative tumor size, histology, margin status and lymph node involvement were similar. Among upstaged, 9 patients (8.6%) developed first recurrence as compared to only 3 (0.7%) in those not upstaging (P <0.001). The median time to recurrence (57 vs. 107 months; P <0.001) was lesser in de novo pT3a renal tumors. CONCLUSIONS: Pathological upstaging from cT1 to pT3a and necrosis on histopathology were associated with recurrence. Advanced age, smoking, necrosis on histopathology, clear cell histology and higher Fuhrman grades contributed to pathological upstaging of cT1 tumors. De novo pT3a RCC had worse survival when compared to cT1 patients upstaging to pT3a RCC.

Focal laser ablation as clinical treatment of prostate cancer: report from a Delphi consensus project.

PURPOSE: To define the role of focal laser ablation (FLA) as clinical treatment of prostate cancer (PCa) using the Delphi consensus method. METHODS: A panel of international experts in the field of focal therapy (FT) in PCa conducted a collaborative consensus project using the Delphi method. Experts were invited to online questionnaires focusing on patient selection and treatment of PCa with FLA during four subsequent rounds. After each round, outcomes were displayed, and questionnaires were modified based on the comments provided by panelists. Results were finalized and discussed during face-to-face meetings. RESULTS: Thirty-seven experts agreed to participate, and consensus was achieved on 39/43 topics. Clinically significant PCa (csPCa) was defined as any volume Grade Group 2 [Gleason score (GS) 3+4]. Focal therapy was specified as treatment of all csPCa and can be considered primary treatment as an alternative to radical treatment in carefully selected patients. In patients with intermediate-risk PCa (GS 3+4) as well as patients with MRI-visible and biopsy-confirmed local recurrence, FLA is optimal for targeted ablation of a specific magnetic resonance imaging (MRI)-visible focus. However, FLA should not be applied to candidates for active surveillance and close follow-up is required. Suitability for FLA is based on tumor volume, location to vital structures, GS, MRI-visibility, and biopsy confirmation. CONCLUSION: Focal laser ablation is a promising technique for treatment of clinically localized PCa and should ideally be performed within approved clinical trials. So far, only few studies have reported on FLA and further validation with longer follow-up is mandatory before widespread clinical implementation is justified.

Medium-term Follow-up of Vascular-targeted Photodynamic Therapy of Localized Prostate Cancer Using TOOKAD Soluble WST-11 (Phase II Trials).

BACKGROUND AND OBJECTIVE: To assess the medium-term tumor control in patients with localized prostate cancer (PCa) treated with vascular-targeted photodynamic (VTP) therapy with TOOKAD Soluble WST11 (VTP) and to assess the medium-term tolerability of the treatment. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTION: During the clinical phase II studies, 68 patients were treated with VTP under optimal treatment conditions (WST11 at 4mg/kg, light energy at 200J/cm, and a light density index ≥1) and have been included in a 3.5-yr follow-up. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Post-interventional visits were scheduled every 6 mo and conducted as per local standard practice in each study center. Cancer-free status was assessed by means of prostate-specific antigen kinetics, multiparametric magnetic resonance imaging and/or prostate biopsies. RESULTS AND LIMITATIONS: At the end of the 3.5-yr follow-up, overall successful focal ablation was achieved for 51 patients (75%). Cancer was identified in the untreated lobe in 17 patients (25%). In total, 34 patients (50%) were cancer-free in both the prostate lobes. In case of recurrent/persistent malignancy, the Gleason score remained consistent or changed at the maximum by one point (upgrading by 1 Gleason point to 3+4 for eight patients and 4+3 for two patients). There were 64 related adverse events (AEs): 48% were Clavien grade I, 47% were grade II, and 5% were grade III. There were no Clavien grade IV and V AEs. Limitations included small sample size and heterogeneity in the follow-up for some centers. CONCLUSIONS: VTP is a safe and efficient treatment and represents an alternative option for localized low-risk PCa management over the medium term. Precise diagnostic methods and imaging tools are thereby essential requirements to ensure safe and complete targeted therapy. PATIENT SUMMARY: In this report, we looked at the medium-term outcomes of focal photodynamic therapy for early-stage prostate cancer. We found that this form of treatment is efficient and might have the potential to become a therapeutic option for low-risk cancer. Effectiveness depends on precise diagnostic methods, such as magnetic resonance imaging and accurate biopsy.
