ABSTRACT

BACKGROUND: Androgen deprivation therapy (ADT) is foundational in the management of advanced prostate cancer (PCa) and has benefitted from a recent explosion in scientific advances. These include approval of new therapies that suppress testosterone (T) levels or inactivate its function, improvements in diagnostic and assay technologies, identification of lower therapeutic targets for T, discovery of the relevance of germline genetic mutations and identification of the benefits of sequential and combination therapies. METHODS: This review discusses the clinical profiles of the most up-to-date options for ADT, best practices for managing patients with advanced PCa and future directions in therapy. RESULTS AND CONCLUSIONS: Modern assay technologies reveal that bilateral orchiectomy results in a serum T level of approximately 15 ng/dL as compared to the historical definition of castration of T < 50 ng/dL. Evidence shows that lowering T levels to <20 ng/dL improves patient survival and delays disease progression. Routine monitoring of T in addition to prostate-specific antigen throughout treatment is important to ensure continuing efficacy of T suppression. New drugs that inhibit androgen signaling in combination with traditional ADT suppress T activity to near zero and have significantly improved patient survival. When personalizing ADT regimens physicians should consider a number of factors including initiation and duration of ADT, monitoring of T levels and PSA, the possibility of switching monotherapies if a patient does not achieve adequate T suppression, and consideration of intermittent vs. continuous ADT according to patients' lifestyles, comorbidities, risk factors and tolerance to treatment.

ABSTRACT

OBJECTIVE: To evaluate the surgical morbidity and effectiveness in improving symptoms of benign prostatic hyperplasia (BPH), comparing 'button-type' bipolar plasma vaporisation (BTPV) vs transurethral resection of the prostate (TURP). METHODS: We conducted a literature search of published articles until November 2014. Only prospective and randomised studies with comparative data between BTPV and conventional TURP (mono- or bipolar) were included in this review. RESULTS: Six articles were selected for the analyses. In the 871 patients evaluated, 522 underwent TURP and 349 BTPV. There was a tendency for a higher transfusion rate in the TURP group, with two BTPV cases (0.006%) and 16 TURP cases (0.032%) requiring transfusions (P = 0.06). The number of complications was similar between the groups (odds ratio 0.33, 95% confidence interval [CI] 0.8-1.31; P = 0.12; I(2) = 86%). When subdivided by severity, 10.7% (14/131) and 14.6% (52/355) of complications were classified as severe (Clavien 3 or 4) in patients who underwent BTPV and TURP, respectively (P = 0.02). The average duration of indwelling catheterisation was significantly less in patients who underwent BTPV (standardised mean difference [SMD] -0.84; 95% CI -1.54 to 0.14; P = 0.02; I(2) = 81%). Both treatments significantly improved symptoms and the postoperative International Prostate Symptom Score was similar in both groups (SMD 0.09, 95% CI -1.56 to 1.73; P = 0.92). CONCLUSION: BTPV is an effective and safe treatment for BPH. The improvement of urinary symptoms and overall complications are comparable to conventional TURP. However, BTVP appears to be associated with a lower rate of major complications and duration of indwelling catheterisation.

ABSTRACT

Introduction Open inguinal lymphadenectomy is the gold standard for the treatment of inguinal metastasis in patients with penile cancer (PC). Recently the Video Endoscopic Inguinal Lymphadenectomy (VEIL) was proposed as an option to reduce the morbidity of the procedure in patients without palpable inguinal lymph nodes (PILN), however the oncological equivalency in patients with PILN remains poorly studied. The aims of this video are the demonstration of VEIL in patients with PILN and present the preliminary experience comparing patients with and without PILN. Materials and Methods The video illustrates the procedure performed in two cases that were previously underwent partial penectomy for PC with PILN. Data from the series of 15 patients (22 limbs operated) with PILN underwent VEIL were compared with our series of VEIL in 25 clinically N0 patients (35 limbs operated). Results The comparison between the groups with and without PILN found, respectively, these outcomes: age 52,45 × 53,2 years, operative time 126,8 × 95,5 minutes, hospital stay 5. × 3.1 days, drainage time 6.7 × 5.7 days, 9 resected lymph nodes on average in both groups, global complications 32% × 26%, cellulitis 4.5% × 0%, lymphocele 23% in both groups, skin necrosis 0% × 3%, myocutaneous necrosis 4.5% × 0%, pN+ 33% × 32%, cancer specific mortality 7% × 5% and mean follow-up 17.3 × 35.3 months. None of the variables presented p < 0.05. Conclusions VEIL is a safe complementary procedure for treatment of PC, even in patients with PILN. Oncological results in patients with PILN seem to be appropriate but are still very premature. Prospective multicenter studies with larger samples and long-term follow-up should be conducted to determine the oncological equivalence of VEIL compared with open surgery in patients with PILN. .

ABSTRACT

The aim of this study was to evaluate the diagnostic and potential prognostic value of cell-free plasma DNA (CF-pDNA) in patients with suspected or histologically proven prostate cancer (PCa). We included 133 men with a diagnosis of PCa and 33 controls. PCa patients had blood samples prospectively drawn every 3 months for 2 years. CF-pDNA was measured by spectrophotometry. Considering a cut-off value of 140 ng/mL of CF-pDNA the area under the curve was of 0.824(0.757-0.879 with a sensitivity = 66.2 % and a specificity = 87.9 %) and the positive and negative likelihood ratio were of 5.46 and 0.39, respectively. CF-pDNA tends to decrease slightly and return to baseline values in about a week after biopsy. There was no statistical significant correlation between CF-pDNA levels at study entry with PSA, Gleason score, stage and biochemical recurrence free survival (BRFS). However, with a mean follow-up of 13.5 months, we could observe a significant shorter BRFS for patients with at least one value above 140 ng/mL of CF-pDNA during follow-up (p = 0.048). CF-pDNA is a potentially valuable biomarker for PCa diagnosis and a potential tool for the follow-up of patients with PCa.

ABSTRACT

PURPOSE: The indication for surgery in locally advanced prostate cancer is growing considering and long-term follow-up shows that 60-80% of patients can be free of clinical recurrence. The aim of this video is demonstrate the modifications in traditional laparoscopic surgery that permit to observe the oncological principles reproducing open surgery. MATERIALS AND METHODS: A 55 years-old male presented with an initial PSA = 25ng/dL, the digital rectal examination found a prostate with hardened nodules bilaterally (clinical stage T2c). Prostate biopsy showed an adenocarcinoma Gleason 7, the patient's disease was classified as a localized high-risk prostate cancer. Surgery was offered as initial therapeutic option and the critical technical points were: transperitoneal approach to evaluate if separation of rectum from prostate and seminal vesicles was possible, extended pelvic lymphadenectomy, opening of endopelvic fascia lateral to the prostate, bladder neck section without preservation, pedicle control without neurovascular bundle preservation, meticulous dissection of apical region, reconstruction of posterior bladder neck before the anastomosis. RESULTS: The operative time was 240 minutes without conversion to open surgery and an estimated blood loss around 520 mL. Neither intraoperative nor postoperative complications occurred and the hospital stay was about 36 hours. Pathological report confirmed a prostate adenocarcinoma Gleason 4+4, negative margins and stage pT3a pN0 pMx. CONCLUSIONS: Laparoscopic surgery adopting oncological principles can be utilized with efficacy to selected patients with high risk localized and locally advanced prostate cancer maintaining the advantages of minimally invasive surgical approach.

ABSTRACT

INTRODUCTION: Pelvic organ prolapse is an ordinary disease with around 200.000 surgeries performed annually in the US to treat this condition. The surgical treatment for complete vaginal vault prolapse after hysterectomy involves abdominal or vaginal sacrocolpopexy. The purpose of this video is to demonstrate the steps of a laparoendoscopic single-site surgery (LESS) sacrocolpopexy performed by a simplified knotless technique. MATERIALS AND METHODS: A 52 year-old female submitted a total hysterectomy five years ago due to miomatosis who developed vault prolapse and urinary incontinence after surgery. She was treated by transumbilical LESS cutaneous retractor and a surgical glove attached to three trocars through a 3.5 cm umbilical incision. Patient was positioned in lithotomy, the Y-shape polypropylene mesh was passed through the trocar. Only conventional laparoscopic instruments were used for intrabdominal dissection of vagina and peritoneum. The mesh was fixed to the vaginal fornix using 3 continuous sutures held in extremities by polymeric clips. The last helical suture was fixed by polymeric clips to the sacral periosteum from the promontory to achieve good vaginal positioning without tension. The posterior peritoneum was closed over the mesh. RESULTS: The operative time was 150 minutes, blood loss of approximately 100 mL and the patient was discharged after 18 hours with no immediate complications and a 3 months follow-up free of vault prolapse and urinary incontinence until now. CONCLUSIONS: LESS sacrocolpopexy performed with conventional instruments is feasible and a safe procedure reproducing surgical steps of conventional laparoscopic or robotic surgery.

ABSTRACT

OBJECTIVE: To perform a systematic review and meta-analysis of all randomized controlled trials comparing the efficacy of Sipuleucel-T versus placebo for asymptomatic or minimally symptomatic metastatic castration-refractory prostate cancer (mCRPC). MATERIALS AND METHODS: Several databases were searched, including MEDLINE, EMBASE, LILACS, and CENTRAL. The endpoints were overall survival (OS), time to progression (TTP) and side effects. We performed a meta-analysis (MA) of the published data. The results are expressed as Hazard Ratio (HR) or Risk Ratio (RR), with their corresponding 95% confidence intervals (CI 95%). RESULTS: The final analysis included 3 trials comprising 737 patients. The TTP was similar in patients who received Sipuleucel-T or placebo (fixed effect: HR = 0.89; CI 95% = 0.75 to 1.05; p = 0.16), with no heterogeneity detected on this analysis (Chi2 = 2.14, df = 2 (P = 0.34); I2 = 6%). The results showed a higher overall survival in patients treated with Sipuleucel-T (fixed effect: HR = 0.74; CI 95% = 0.61 to 0.89; p = 0.001; NNT = 3). We found no heterogeneity on this analysis either (Chi2 = 1.46, df = 2 (P = 0.48); I2 = 0%). The incidence of adverse events (grade > 3) was the same in both groups. CONCLUSION: Sipuleucel-T prolongs overall survival in patients with asymptomatic or minimally symptomatic mCRPC.

ABSTRACT

PURPOSE: To compare the efficacy of three different formulations containing Betamethasone Valerate versus placebo in the topical treatment of phimosis. As a secondary goal, we compared the outcomes after 30 and 60 days of treatment. MATERIALS AND METHODS: Two hundred twenty boys aged 3 to 10 years old with clinical diagnosis of phimosis were enrolled. Patients were randomized to one of the following groups: Group 1: Betamethasone Valerate 0.2% plus Hyaluronidase; Group 2: Betamethasone Valerate 0.2%; Group 3: Betamethasone Valerate 0.1% or Group 4: placebo. Parents were instructed to apply the formula twice a day for 60 days and follow-up evaluations were scheduled at 30, 60 and 240 days after the first consultation. Success was defined as complete and easy foreskin retraction. RESULTS: One hundred ninety-five patients were included at our final analysis. Group 1 (N = 54), 2 (N = 51) and 3 (N = 52) had similar success and improvement rates, all treatment groups had higher success rates than placebo (N = 38). After 60 days of treatment, total and partial response rates for Groups 1, 2 and 3 were 54.8% and 40.1%, respectively, while placebo had a success rate of 29%. Success and improvement rates were significantly better in 60 days when compared to 30 days. CONCLUSIONS: Betamethasone Valerate 0.1%, 0.2% and 0.2% in combination with Hyaluronidase had equally higher results than placebo in the treatment of phimosis in boys from three to ten years-old. Patients initially with partial or no response can reach complete response after 60 days of treatment.

ABSTRACT

The aim of the study was to analyze the distribution of the methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR), and methionine synthase (MTR) polymorphisms in idiopathic infertile Brazilian men and fertile men. Case-control study comprising 133 idiopathic infertile Brazilian men with nonobstructive azoospermia ([NOA] n = 55) or severe oligozoospermia ([SO] n = 78) and 173 fertile men as controls. MTHFR C677T, A1298C, and G1793A; MTRR A66G; and MTR A2756G polymorphisms were studied by quantitative polymerase chain reaction (qPCR). The results were analyzed statistically and a P value <.05 was considered significant. Single-marker analysis revealed a significant association among MTHFR C677T polymorphism and both NOA group (P = .018) and SO group (P < .001). Considering the MTHFR A1298C, MTHFR G1793A, and MTRR A66G polymorphisms, no difference was found between NOA group and SO group. Regarding the MTR A2756G polymorphism, a significant difference was found between NOA and controls, P = .017. However, statistical analysis revealed no association between SO group and controls. Combined genotypes of 3 MTHFR polymorphisms did not identify a haplotype associated with idiopathic infertility. The combinatory analysis of the 3 polymorphisms MTHFR, MTRR, and MTR did not show difference between cases and controls. The findings suggest the MTHFR C677T and MTR A2756G polymorphisms could be an important genetic factor predisposing to idiopathic infertility in Brazilian men.

ABSTRACT

Techniques that attempt to further reduce the morbidity and improve cosmesis of laparoscopic surgery have particularly generated interest. Since its initial urologic description in 2007, there has been a surge of interest in laparoendoscopic single-site surgery, which is now an emerging technique within the field of minimally invasive urologic surgery. This report describes a preliminary experience with single-site video endoscopic inguinal lymphadenectomy (SSVEIL) compared with conventional video endoscopic inguinal lymphadenectomy (VEIL) on inguinal nodes management in a 45-year-old man with pT(2) grade 2 squamous cell penile carcinoma and impalpable inguinal nodes. VEIL with saphenous vein preservation in the left leg and SSVEIL on the other side presented no difference concerning operative time (100 vs 120 min), blood loss (50 mL), drainage volume, number of nodes retrieved (8), pain, and oncologic outcome. The patient had an uneventful postoperative course, was discharged 12 hours after the procedure, and preferred the aesthetic result of SSVEIL. Further refinements in technology will likely alleviate many of the persistent technical problems. Additional rigorous comparison studies are needed to evaluate the true benefits of the technique and the extent of its clinical application, mainly oncologic results, before the widespread adoption of SSVEIL. Ultimately, advance breakthroughs in fields of in-vivo instrumentation, robotics, and purpose-built robotic platforms will bring its potential to full clinical realization.

ABSTRACT

A comprehensive literature study was conducted to evaluate the levels of evidence (LEs) in publications on the diagnosis and staging of penile cancer. Recommendations from the available evidence were formulated and discussed by the full panel of the International Consultation on Penile Cancer in November 2008. The final grades of recommendation (GRs) were assigned according to the LEs of the relevant publications. The following consensus recommendations were accepted: physical examination of the primary penile lesion is mandatory, evaluating the morphologic and physical characteristics of the lesion (GR A). Evaluation of the primary lesion with ultrasonography is of limited value for local tumor staging (GR C); however, evaluation of the primary tumor with magnetic resonance (MRI) imaging during artificial erection induced by intracavernosal injection of prostaglandin might be more useful (GR B). Histologic or cytologic diagnosis of the primary lesion is mandatory (GR A). For accurate histologic grading and staging, a resected specimen is preferable to a biopsy specimen alone (GR B). Penile cancer should be staged according to the TNM system; however, the 1987/2002 TNM staging system requires revision using data from larger patient cohorts to validate the recently proposed modifications (GR B). The histopathology report should provide information on all prognostic parameters, including the tumor size, histologic type, grade, growth pattern, depth of invasion, tumor thickness, resection margins, and lymphovascular and perineural invasion (GR B). Physical examination of the inguinal and pelvic areas to assess the lymph nodes is mandatory (GR B). Ultrasound-guided fine needle aspiration cytology is indicated for both palpable and nonpalpable inguinal nodes. If the findings confirm lymph node metastasis (LNM), complete inguinal lymph node dissection is indicated (GR B). In patients with nonpalpable inguinal nodes, if the ultrasound-guided fine needle aspiration cytology findings are negative for tumor, dynamic sentinel node biopsy can be performed if the equipment and technical expertise are available (GR C). In patients at high risk of inguinal LNM according to the available guidelines and nomograms, surgical staging can be performed by complete, bilateral inguinal lymph node dissection, which might also be curative (GR B). In patients at intermediate risk of LNM, sentinel node biopsy or modified (limited) inguinal lymph node dissection might be performed (GR B). In patients with nonpalpable inguinal nodes, imaging with computed tomography (CT) or MRI is not indicated, because they are not useful in detecting small-volume LNM. Also, it is very unlikely that large-volume LNM (detectable by CT/MRI) would be present in the pelvic nodes (GR B). In patients with confirmed inguinal LNM, CT of the pelvis is indicated to detect iliac LNMs (GR B). Abdominal CT and chest radiography are advisable if the pelvic CT findings are positive (GR B).

ABSTRACT

PURPOSE: Penile carcinoma is a rare but mutilating malignancy. In this context, partial penectomy is the most commonly applied approach for best oncological results. We herein propose a simple modification of the classic technique of partial penectomy, for better cosmetic and functional results. TECHNIQUE: If partial penectomy is indicated, the present technique can bring additional benefits. Different from classical technique, the urethra is spatulated only ventrally. An inverted "V" skin flap with 0.5 cm of extension is sectioned ventrally. The suture is performed with vicryl 4-0 in a "parachute" fashion, beginning from the ventral portion of the urethra and the "V" flap, followed by the "V" flap angles and than by the dorsal portion of the penis. After completion of the suture, a Foley catheter and light dressing are placed for 24 hours. CONCLUSIONS: Several complex reconstructive techniques have been previously proposed, but normally require specific surgical abilities, adequate patient selection and staged procedures. We believe that these reconstructive techniques are very useful in some specific subsets of patients. However, the technique herein proposed is a simple alternative that can be applied to all men after a partial penectomy, and takes the same amount of time as that in the classic technique. In conclusion, the "parachute" technique for penile reconstruction after partial amputation not only improves the appearance of the penis, but also maintains an adequate function.

ABSTRACT

BACKGROUND: Osteoporosis could be associated with the hormone therapy for metastatic prostate carcinoma (PCa) and with PCa per se. The objective of this review is to determine the incidence of bone loss and osteoporosis in patients with PCa who are or are not treated with hormone therapy (ADT). METHODS: The Medline, Embase, Cancerlit, and American Society of Clinical Oncology Abstract databases were searched for published studies on prostate cancer and bone metabolism. The outcomes assessed were: fracture, osteoporosis and osteopenia. RESULTS: Thirty-two articles (116,911 participants) were included in the meta-analysis. PCa patients under ADT had a higher risk of osteoporosis (RR, 1.30; p < 0.00001) and a higher risk of fractures (RR, 1.17; p < 0.00001) as compared to patients not under ADT. The total bone mineral density was lower in patients under ADT when compared with patients not under ADT (p = 0.031) but it was similar to bone mineral density found in healthy controls (p = 0.895). The time of androgen deprivation therapy correlated negatively with lumbar spine and total hip bone mineral density (Spearman's rho = -0.490 and -0.773; p = 0.028 and 0.001, respectively) and with total hip t score (Spearman's rho = -0.900; p = 0.037). CONCLUSION: We found consistent evidence that the use of androgen deprivation therapy in patients with PCa reduces bone mineral density, increasing the risk of fractures in these patients.

PURPOSE: Penile carcinoma is a rare but mutilating malignancy. In this context, partial penectomy is the most commonly applied approach for best oncological results. We herein propose a simple modification of the classic technique of partial penectomy, for better cosmetic and functional results. TECHNIQUE: If partial penectomy is indicated, the present technique can bring additional benefits. Different from classical technique, the urethra is spatulated only ventrally. An inverted "V" skin flap with 0.5 cm of extension is sectioned ventrally. The suture is performed with vicryl 4-0 in a "parachute" fashion, beginning from the ventral portion of the urethra and the "V" flap, followed by the "V" flap angles and than by the dorsal portion of the penis. After completion of the suture, a Foley catheter and light dressing are placed for 24 hours. CONCLUSIONS: Several complex reconstructive techniques have been previously proposed, but normally require specific surgical abilities, adequate patient selection and staged procedures. We believe that these reconstructive techniques are very useful in some specific subsets of patients. However, the technique herein proposed is a simple alternative that can be applied to all men after a partial penectomy, and takes the same amount of time as that in the classic technique. In conclusion, the "parachute" technique for penile reconstruction after partial amputation not only improves the appearance of the penis, but also maintains an adequate function.

ABSTRACT

INTRODUCTION: Two positions have been reported for ureteroscopy (URS): dorsal lithotomy (DL) position and dorsal lithotomy position with same side leg slightly extended (DLEL). The aim of the present study was to compare the outcomes associated with URS performed with patients in DL vs. DLEL position. MATERIALS AND METHODS: A total of 98 patients treated for ureteral calculi were randomized to either DL or DLEL position during URS, and were prospectively followed. Patients, stone characteristics and operative outcomes were evaluated. RESULTS: Of the 98 patients included in the study, 56.1% were men and 43.9% women with a mean age of 42.6 +/- 16.8 years. Forty-eight patients underwent URS in DL position and 50 in DLEL position. Patients' age, mean stone size and location were similar between both groups. Operative time was longer for the DL vs. DLEL group (81.0 vs. 62.0 minutes, p = 0.045), mainly for men (95.2 vs. 63.9 minutes, p = 0.023). Mean fluoroscopy use, complications and success rates were similar between both groups. CONCLUSIONS: Most factors associated with operative outcomes during URS are inherent to patient's condition or devices available at each center, and therefore cannot be changed. However, leg position is a simple factor that can easily be changed, and directly affects operative time during URS. Even though success and complication rates are not related to position, placing the patient in dorsal lithotomy position with an extended leg seems to make the surgery easier and faster.
