RESUMEN
Nearly 15% of individuals with localized prostate cancer are identified as high risk for recurrence and progression of the disease, which is why the correct staging is vital for the definition of correct treatment-also developing novel therapeutic strategies to find a balance between getting better outcomes without sacrificing the quality of life (QoL). In this narrative review, we introduced the current standards of staging and primary treatment of high-risk localized prostate cancer (PCa), based on international guidelines and arguments in the debate, under the light of the most recent literature. It brings essential tools such as PSMA PET/CT and different nomograms (Briganti. MSKCC, Gandaglia) for accurate staging and selecting wisely the definitive therapy. Even though there is a broad discussion over the best local treatment in curative-intent treatment, it looks more important to define which patient profile would adapt correctly to every different treatment, highlighting the benefits and superior outcomes with multimodal treatment.

Objective: Radical prostatectomy is the recommended treatment for localized prostate cancer; however, it is an invasive procedure that can leave serious morbidity. Robot-assisted radical prostatectomy was introduced with the aim of reducing postoperative morbidity and facilitating rapid recovery compared to the traditional Walsh's open radical retropubic prostatectomy. Therefore, a protocol was developed to perform an open prostatectomy comparable to that performed by robotics, but without involving novel instrumentation. Methods: A total of 220 patients diagnosed with localized prostate cancer underwent radical prostatectomy. They were divided into two groups: anterograde technique (115 patients) and the retrograde method (105 patients). The study outcomes were observed 3 months after surgery. Results: No differences were found in terms of surgical time, hospital stay, and suction drainage. However, reduced bleeding was observed in the anterograde technique (p=0.0003), with rapid anastomosis duration (p=0.005). Among the patients, 60.9% undergoing the anterograde technique were continent 3 months after surgery compared to 42.9% treated by the retrograde method (p=0.007). Additionally, fewer complications in terms of the number (p=0.007) and severity (p=0.0006) were observed in the anterograde technique. Conclusion: The anterograde method displayed increased efficiency in reducing complications, compared to the retrograde technique.
RESUMEN
BACKGROUND: According to pathologico-clinical features, patients diagnosed with localized prostate cancer (PCa) are stratified into distinct risk groups (low-risk, intermediate-risk or high-risk). Data have demonstrated that 68Gallium-prostate-specific membrane antigen positron emission tomography (68Ga-PSMA PET/CT) is superior to conventional radiological exams (CT or MRI and bone scintigraphy) in the primary staging of high-risk localized PCa. However, it is still unknown if in a population of high-risk PCa, there would be a subgroup of patients with a higher probability of identifying metastatic disease by the 68Ga-PSMA PET/CT. MATERIALS AND METHODS: Data from patients with localized PCa who underwent 68GA-PSMA PET/CT for primary staging from four institutions were retrospectively collected. We selected patients with at least one D'Amico classification risk factor (International Society of Urological Pathology ≥ IV and/or prostate-specific antigen > 20 ng/ml). To detect an association between extent of disease and number of risk factors as well as International Society of Urological Pathology prostate cancer grade, contingency tables were used, and Fisher Exact Test was performed. RESULTS: Between 2016 and 2020, 60 patients underwent a 68GA-PSMA PET/CT for primary staging of high-risk localized PCa. Regarding the number of risk factors, 37 patients (62%) had one risk factor, and 23 (38%) had two risk factors. In the subgroup of patients with metastatic disease (n = 22), those with two risk factors had higher incidence of metastatic disease, and it was statistically significant (p = 0.011). CONCLUSION: This retrospective analysis demonstrated that 68GA-PSMA PET/CT was able to identify advanced disease in more than one-third of patients with high-risk disease especially those with two adverse risk factors.
RESUMEN
Introducción: Las variables relevantes preoperatorias con que cuenta el urólogo para una toma de decisión frente a un cáncer prostático localizado son: la edad, el tacto rectal, el antígeno prostático específico (APE) e informe histológico de la biopsia por punción con el Gleason. Además se pueden incluir otras variables como el volumen prostático, número de muestras de biopsias positivas, porcentaje de la muestra comprometida, etc. Nosotros quisimos evaluar el grado de concordancia entre el diagnóstico clínico-patológico preoperatorio con el hallazgo histológico, posoperatorio en pacientes prostatectomizados, debido a la implicancia pronóstica y en la toma de decisión que pudiese tener. Material y Método: Se estudiaron retrospectivamente 119 prostatectomías radicales entre marzo de 2004 y junio de 2009. Se consideraron: edad, tacto, antígeno prostático específico (APE) y score de Gleason. Se excluyeron pacientes con tratamiento antiandrogénico u hormonal neoadjuvante. Resultados: En el preoperatorio la mediana de edad fue de 66 años (61-68), de APE 7,35 ng/ml (5,38-11,8) y de Gleason fue de 6 (5-7). El 87,4 por ciento de los pacientes tenía un APE >4,0 ng/ml. El 54 por ciento (n= 64) tenía un estadio clínico T1c y el 46 por ciento (n= 55) un estadio T2. En el posoperatorio 23,5 por ciento (n= 28) tuvo un estadio pT2 y el 74 por ciento (n= 88) un estadio pT3. En pacientes con estadio pT2 el APE preoperatorio fue de 5,9 ng/ml (4,4-9,4), en el estadio pT3 fue de 7,9 ng/ml (5,7-12,8). El score de Gleason en pT2 fue de 5 (5-6), en el pT3 fue de 6 (5-7). No encontramos diferencia de edad en los estadios pT2 (67 años) y pT3 (68 años). Conclusiones: En el estudio histopatológico posoperatorio de pacientes con estadio clínico T1c y T2, se confirmó un estadio pT2 sólo en 23,5 por ciento, el 74 por ciento tenían un estadio pT3 (a, b). En el cáncer prostático localizado, el tacto rectal no fue útil en su correlación con el estadio histológico...
Introduction: Relevant preoperative variables in patients with localized prostate cancer are: age, digital rectal examination (DRE), prostatic specific antigen (PSA) level and Gleason score in the transrectal biopsy. Other variables include prostate volume, number of positive biopsy samples, percentage of involvement in the biopsy, etc. We evaluated the agreement between the preoperative clinico pathologic diagnosis and the postoperative histology report in patients submitted to prostatectomy. Material and method: This is a retrospective review of 119 radical prostatectomies performed between March 2004 and June 2009. We recorded age, DRE, PSA level, and Gleason score. Patients receiving anti-androgenic treatment or neoadjuvant hormonal treatment were excluded. Results: Preoperative findings: median age was 66 years (61-68), median PSA level was 7.35 ng/ml(5.38-11.8) and median Gleason score was 6 (5-7). PSA level >4 ng/ml was found in 87.4 percent of the patients. Clinical stage T1c was found in 54 percent (n=64) of the cases whereas 46 percent (n=55) were stage T2. Postoperative findings: stage pT2 was found in 23.5 percent (n=28) of the patients whereas 74 percent (n =88)were pT3 stage. In pT2 patients, preoperative PSA was 5,9 ng/ml (4.4-9.4). In pT3 patients, PSA was7.9 ng/ml (5.7-12.8). Gleason score in pT2 was 5 (5-6); in pT3 patients, Gleason score was 6 (5-7). No age difference was found between pT2 stage (67 years) and pT3 stage (68 years).Conclusions: Postoperative histology in patients with T1c and T2 stages confirmed a pT2 stage only in 23.5 percent of the cases; 74 percent of the cases were pT3 (a,b) stage. In localized prostate cancer, DRE was not useful for the correlation with pathologic staging, especially for stage pT3 cases. Preoperative Gleason score was relatively useful; we found understaging 36.2 percent of the cases and overstaging 21.8 percent of the patients. These variables should be considered in the initial evaluation of...
