RESUMO

ABSTRACT Background Radical prostatectomy (RP) has been used as the main primary treatment for prostate cancer (PCa) for many years with excellent oncologic results. However, approximately 20-40% of those patients has failed to RP and presented biochemical recurrence (BCR). Prostatic specific antigen (PSA) has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment. The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality (CSM). Review design A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Objective To provide an updated assessment of BCR definition, its meaning, PCa natural history after BCR and the weight of each clinical/pathological feature and risk group classifications in BCR, metastatic disease and CSM.

RESUMO

INTRODUCTION AND OBJECTIVE: Focal cryotherapy emerged as an efficient option to treat favorable and localized prostate cancer (PCa). The purpose of this video is to describe the procedure step by step. MATERIALS AND METHODS: We present the case of a 68 year-old man with localized PCa in the anterior aspect of the prostate. RESULTS: The procedure is performed under general anesthesia, with the patient in lithotomy position. Briefly, the equipament utilized includes the cryotherapy console coupled with an ultrasound system, argon and helium gas bottles, cryoprobes, temperature probes and an urethral warming catheter. The procedure starts with a real-time trans-rectal prostate ultrasound, which is used to outline the prostate, the urethra and the rectal wall. The cryoprobes are pretested and placed in to the prostate through the perineum, following a grid template, along with the temperature sensors under ultrasound guidance. A cystoscopy confirms the right positioning of the needles and the urethral warming catheter is installed. Thereafter, the freeze sequence with argon gas is started, achieving extremely low temperatures (-40ºC) to induce tumor cell lysis. Sequentially, the thawing cycle is performed using helium gas. This process is repeated one time. Results among several series showed a biochemical disease-free survival between 71-93% at 9-70 month- follow-up, incontinence rates between 0-3.6% and erectile dysfunction between 0-42% (1-5). CONCLUSIONS: Focal cryotherapy is a feasible procedure to treat anterior PCa that may offer minimal morbidity, allowing good cancer control and better functional outcomes when compared to whole-gland treatment.

RESUMO

PURPOSE: To evaluate whether patients with prostate cancer have worse functional urinary recovery with focal brachytherapy (FBT) at the base versus the apex of the prostate. METHODS AND MATERIALS: The functional outcomes of patients treated with FBT at the base of the prostate were compared with those of patients treated with FBT at the apex. Urinary symptoms, continence, and erectile dysfunction were measured using the International Prostate Symptom Score (IPSS), International Continence Score (ICS), and International Index of Erectile Function (IIEF-5) questionnaires, respectively, at baseline and at 6, 12, and 24 months after treatment. RESULTS: Twenty-eight and 13 patients were treated with FBT at the apex and the base, respectively, of the prostate. A significant difference between groups was found in the IPSS score at 6 months (mean IPSS: apex 6.4 ± 4.7, base 10.6 ± 5.7; p = 0.02), but not at baseline or at 12 and 24 months after treatment. On multivariate analysis, only FBT at the base of the prostate remained an independent predictor of worsening urinary symptoms (odds ratio, 5.8; p = 0.04). CONCLUSIONS: At 6 months after FBT, significantly less urinary toxicity was found in patients who underwent FBT at the apex versus the base of the prostate. Continence and sexual side effects were minimal in all patients.

RESUMO

PURPOSE: We assessed the impact of focal therapy on perioperative, oncologic and functional outcomes in men who underwent salvage robotic assisted radical prostatectomy compared to primary robotic assisted radical prostatectomy. MATERIALS AND METHODS: Focal therapy was performed in patients presenting with Gleason score 3 + 3 or 3 + 4, clinical stage cT2a or less, serum prostate specific antigen 15 ng/ml or less, unilateral positive biopsy, maximum length of any positive core less than 10 mm and life expectancy greater than 10 years. Focal therapy was defined as target ablation of the index lesion plus a 1 cm safety margin in the normal ipsilateral prostatic parenchyma. The salvage group included 22 men who underwent salvage prostatectomy after focal therapy failure. The primary group was defined using matched pair 1:2 selection of 44 of 2,750 patients treated with primary prostatectomy. The primary and secondary end points were the between group differences in functional and oncologic outcomes, respectively. RESULTS: Complication rates were comparable (p >0.05). Pad-free probability was comparable between the groups at 1 and 2 years (p = 0.8). Recovery of erectile function was significantly lower after salvage robotic assisted radical prostatectomy (p = 0.008), which also showed a significantly lower probability of cumulative biochemical recurrence-free survival compared to primary robotic assisted radical prostatectomy (56.3% vs 92.4% at 2 years, p = 0.001). Salvage prostatectomy demonstrated a significantly increased risk of biochemical recurrence (HR 4.8, 95% CI 1.67-13.76, p = 0.004). Study limitations included the retrospective nature, the lack of randomization and the short followup. CONCLUSIONS: Salvage robotic assisted radical prostatectomy after focal therapy failure is feasible with acceptable complication rates. However, patients assigned to primary focal therapy should be advised about a poorer prognosis in terms of oncologic control and lower erectile recovery rates in case of a future salvage surgery.

RESUMO

PURPOSE: To evaluate the long-term efficacy of prostate cancer control and complication rates, in the elderly, after focal therapy with high-intensity focused ultrasound (HIFU). MATERIALS AND METHODS: Between June 1997 and March 2000, patients with localized prostate cancer were included into a focal therapy protocol. Inclusion criteria were: PSA ≤ 10 ng/mL, ≤ 3 positive biopsies with only 1 lobe involved, clinical stage ≤ T2a, Gleason score ≤ 7 (3+4), negative CT scan and bone scan. Hemi-ablation of the prostate was performed with the Ablatherm® device. Survival, complication rates and urinary continence were evaluated. Control biopsies were performed at 1 year. Treatment failure was defined as a positive biopsy or need for salvage therapy. RESULTS: Twelve patients with a mean age 70 years were included. Median follow-up was 10 years. Control prostate biopsies were negative in 11/12 (91%) patients. Overall survival was 83% (10/12) and cancer specific survival was 100% at 10 years. Two patients died from other causes. Recurrence free survival was 90% (95% CI; 0.71-1) at 5 years, and 38% (95% CI; 0.04-0.73) at 10 years. Five patients had salvage therapy with repeat HIFU (n = 1) or hormonal therapy (n = 4) and all salvage patients were alive at 10 years. No patients developed lymph node or bone metastasis. No patients suffered from urinary incontinence. International Prostate Symptom Score was stable at 1 year. Complications included two urinary tract infections and one episode of acute urinary retention. CONCLUSIONS: Hemi-prostate ablation with HIFU can be safely performed in selected elderly patients with adequate long-term cancer control and low complication rates. Results from larger prospective studies using improved imaging techniques and extensive biopsy protocols are awaited.

RESUMO

Laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) represent novel approaches in urological surgery. To perform a review of the literature in order describe the current status of LESS and NOTES in Urology. References for this manuscript were obtained by performing a review of the available literature in PubMed from 01-01-02 to 15-05-09. Search terms included single port, single site, NOTES, LESS and single incision. A total of 412 manuscripts were initially identified. Out of these, 64 manuscripts were selected based in their urological content. The manuscript features subheadings for experimental and clinical studies, as NOTES-LESS is a new surgical technique and its future evolution will probably rely in initial verified feasibility. A subheading for reviews presents information regarding common language and consensus for the techniques. The issue of complications published in clinical series and the future needs of NOTES-LESS, are also presented.

RESUMO

PURPOSE: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view. MATERIALS AND METHODS: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP) and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy. RESULTS: LRP nuances were reassessed by surgical teams in order to verify possible weaknesses in their performance. Our basic approach was to carefully study the anatomy and pioneer open surgery descriptions in order to standardized and master a technique. The learning curve is presented in terms of an objective evaluation of outcomes for cancer control and functional results. In terms of technique-outcomes, there are several key elements in radical prostatectomy, such as dorsal vein control-apex exposure and nerve sparing with particular implications in oncological and functional results. Major variations among the surgical teams' performance and follow-up prevented objective comparisons in radical prostatectomy. The remarkable evolution of LRP needs to be supported by comprehensive results. CONCLUSIONS: Radical prostatectomy is a complex surgical operation with difficult objectives. Surgical technique should be standardized in order to allow an adequate and reliable performance in all settings, keeping in mind that cancer control remains the primary objective. Reassessing anatomy and a return to basics in surgical technique is the means to improve outcomes and overcome the difficult task of the learning curve, especially in minimally access urological surgery.

RESUMO

OBJECTIVE: To review the current modalities of treatment for localized renal cell carcinoma. MATERIALS AND METHODS: A literature search for keywords: renal cell carcinoma, radical nephrectomy, nephron sparing surgery, minimally invasive surgery, and cryoablation was performed for the years 2000 through 2008. The most relevant publications were examined. RESULTS: New epidemiologic data and current treatment of renal cancer were covered. Concerning the treatment of clinically localized disease, the literature supports the standardization of partial nephrectomy and laparoscopic approaches as therapeutic options with better functional results and oncologic success comparable to standard radical resection. Promising initial results are now available for minimally invasive therapies, such as cryotherapy and radiofrequency ablation. Active surveillance has been reported with acceptable results, including for those who are poor surgical candidates. CONCLUSIONS: This review covers current advances in radical and conservative treatments of localized kidney cancer. The current status of nephron-sparing surgery, ablative therapies, and active surveillance based on natural history has resulted in great progress in the management of localized renal cell carcinoma.

RESUMO

El tratamiento del cáncer vesical de células transicionales con invasión muscular sigue siendo difícil, debido a los múltiples patrones de comportamiento biológico que muestra esta enfermedad. Existe controversia en cuanto a la aplicación de tratamiento sistémico en cáncer invasor vesical y el tiempo ideal de indicación de la quimioterapia perioperatoria. Se presenta una visión general de la terapia sistémica en cáncer invasor vesical.


Defining adequate therapy in every patient with invasive transitional cell carcinoma remains difficult, because multiple biologic behavior patterns can be found in this disease. There is controversy regarding the use of systemic treatment in invasive bladder carcinoma and the momentum for chemotherapy deployment. We present an overview of current trends for systemic treatment in bladder carcinoma.
