Bilateral Cancer in Prostate Biopsy Associates with the Presence of Extracapsular Disease and Positive Surgical Margins in Low Risk Patients: A Consideration for Bilateral Nerve Sparing Radical Prostatectomy Decision

Purpose: To evaluate the epidemiological, clinical and pathological parameters that may predictthe presence of positive surgical margins and extraprostatic disease in patients with low risk [prostatespecific antigen (PSA) < 10, and Gleason score ≤ 6, stage T1c)] prostate cancer.Materials and Methods: We retrospectively analyzed the medical records of patients who hadundergone radical prostatectomy from January 2005 until January 2011. The analysis comprisedpatients’ age, preoperative serum prostate specific antigen (PSA) level, prostate volume, PSA density,biopsy Gleason score, the presence of bilateral disease according to the results of biopsy coresanalysis, the percentage of cancer in biopsy material and the presence of high grade prostatic intraepithelialneoplasia.Results: A total of 117 patients were included in the study. Positive surgical margins were found in37 (31.6%) patients and 23 (19.7%) had advanced disease. The results of the multivariate analysisshowed that bilateral disease was the single significant predictor for advanced disease prediction(P = .04). Same results was obtained by the univariate analysis of the variables for prediction ofpositive surgical margins, where bilateral disease after biopsy cores analysis was the only factor tobe statistical significant (P = .018).Conclusion: Bilateral prostate cancer in prostate biopsy is significantly associated with positivesurgical margins and advanced disease in patients that are operated for prostate cancer of low risk.This observation may assist the selection of patients in whom a bilateral nerve sparing radical prostatectomyis planned to be performed

Percutaneous Nephrolithotomy in a Patient with Mainz Pouch II Urinary Diversion: A Case Report

Abstract: Mainz pouch II is a reliable and viable technique of continent urinary diversion. Patients are at increased risk of long-term complications including urolithiasis of the upper urinary tract and reservoir. We report the case of a 67-year-old male with prior Mainz pouch II due to invasive bladder cancer treated for a large renal calculus. Percutaneous nephrolithotomy (PCNL) was successfully performed. Stone management in these type of patients is of increased interest due to existed &quot;anatomical challenges&quot; concerning the access and safety during the procedure. To our knowledge this is the first case of PCNL in a patient with Mainz pouch II that has been reported in the literature

An 82-year-old Caucasian man with a ductal prostate adenocarcinoma with unusual cystoscopic appearance: a case report

<p>Abstract</p> <p>Introduction</p> <p>Ductal adenocarcinoma is a rare variety of the common acinar adenocarcinoma. It usually presents with refractory symptoms, and during cystoscopy, it is seen as an exophytic lesion at the area of the verumontanum.</p> <p>Case presentation</p> <p>An 82-year-old Caucasian man was diagnosed with ductal adenocarcinoma of the prostate after undergoing transurethral resection of the prostate for urinary retention. Immunohistochemistry confirmed the nature of the tumor. The patient was treated with triptorelin, 3.75 mg once/month, and bicalutamide, 50 mg 1 × 1. The serum prostate-specific antigen at three, six and 12 months after transurethral resection of the prostate was 0.1 ng/ml. The patient remains asymptomatic, and he entered a six-month follow-up protocol.</p> <p>Conclusion</p> <p>Ductal adenocarcinoma often involves the central ducts of the gland and may present as an exophytic papillary lesion in the prostatic urethra. This is why it usually presents with refractory symptoms. The outcome for men with prostatic ductal adenocarcinoma is, in most studies, worse than the outcome for men with prostatic acinar adenocarcinoma. Aggressive management is indicated, even with low-volume metastatic disease.</p

Metastasis to Sartorius Muscle from a Muscle Invasive Bladder Cancer

Bladder cancer constitutes the ninth most common cancer worldwide and approximately only 30% of cases are muscle invasive at initial diagnosis. Regional lymph nodes, bones, lung, and liver are the most common metastases from bladder cancer and generally from genitourinary malignancies. Muscles constitute a rare site of metastases from distant primary lesions even though they represent 50% of total body mass and receive a large blood flow. Skeletal muscles from urothelial carcinoma are very rare and up to date only few cases have been reported in the literature. We present a rare case of 51-year-old patient with metastases to sartorius muscle 8 months after the radical cystectomy performed for a muscle invasive bladder cancer

Clinical Study Early Continence Recovery after Preservation of Maximal Urethral Length until the Level of Verumontanum during Radical Prostatectomy: Primary Oncological and Functional Outcomes after 1 Year of Follow-Up

properly cited. Purpose. To investigate the effect of preventing maximal urethral length until the level of verumontanum during radical prostatectomy on both oncologic and functional outcomes. Patients and Methods. We recruited 329 patients, and they underwent an open radical prostatectomy by a single surgeon. The study cohort was randomized in 2 groups. A standard radical prostatectomy was performed in group A patients, while in group B the urethra was preserved until the level of verumontanum. Results. There was no statistically significant difference between the study groups in terms of positive surgical margins or biochemical relapse. Regarding the functional results, the incidence of incontinence, urgency, and nocturia at 1st month, statistically significant higher rates were seen in group A. In addition, there was a statistically significant difference in the number of pads/day in favor of group B at the 1st, 3rd, and 6th months after surgery. However, this difference was eliminated at 12 months postoperatively. Similar results were seen with the scores of the ICIQ-SF and IIQ-SF questionnaires. Conclusions. Without compromising the oncological outcome, our surgical modificated technique showed earlier recovery of continence in the first 6 months, having though the same rates of continence at 12 months

The impact of surgical modification in oncological and functional outcomes following radical prostatectomy

Purpose: To investigate the effect of a modified surgical technique of open retropubic radical prostatectomy, with preservation of maximal urethral length to the level of verumontanum, in postoperative oncological and functional outcomes.Patients and methods: In this study, 360 patients who underwent open retropubic radical prostatectomy from January 2008 until April 2012 were divided into two groups. Patients of group A underwent the classical procedure of radical prostatectomy as it has been described by Walsh and Donker, while patients of group B underwent the modified technique. The oncological outcomes were evaluated by monitoring PSA value for biochemical failure and by recording the incidence of positive surgical margins. Postoperative incontinence was evaluated by the number of pads/day and through ICIQ-SF and IIQ-SF questionnaires. Postoperative erectile dysfunction was assessed by completing IIEF and SEAR questionnaires. We also recorded and analyzed the effect of the surgical modification in postoperative irritative urinary symptoms.Results: Eighty five patients were excluded from the study. Of the 244 patients who fulfill the inclusion criteria, 115 (47.1%) and 129 (52.9%) patients were included in group A and B, respectively. There was no statistically significant difference in the incidence rates of positive surgical margins (p=0.562) and biochemical recurrence (p=0.321) between the groups. There were significantly higher rates of incontinence (p=0.026), urgency (p<0.001) and nocturia (p<0.001) in patients of group A within the first postoperative month. There was also statistically significant difference in the number of pads/day in favor of group B in 1st (p=0.037), 3rd (p=0.003) and 6th (p=0.032) month after the operation. However, this difference disappeared at 12 months postoperatively. Similar results were observed in the scores of ICIQ-SF and IIQ-SF questionnaires, demonstrating improved outcomes in patients of group B within the first 6 months. There were no differences in the incidence rates of postoperative erectile dysfunction and in the scores of IIEF and SEAR questionnaires, as well.Conclusions: We proposed a modified surgical technique with preservation of maximal urethral length until the anatomical landmark of verumontanum. This technique may reduce the time continence recovery in patients undergoing radical prostatectomy, without compromising the oncological outcome and disease prognosis.Σκοπός: Να διερευνηθεί η επίδρασης μίας τροποποιημένης τεχνικής ριζικής προστατεκτομής, με διατήρηση της ουρήθρας μέχρι το επίπεδο του σπερματικού λοφιδίου, στα μετεγχειρητικά ογκολογικά και λειτουργικά αποτελέσματα.Ασθενείς και μέθοδοι: Στην προοπτική αυτή μελέτη, 360 ασθενείς που υποβλήθηκαν σε ανοικτή οπισθοηβική ριζική προστατεκτομή από τον Ιανουάριο του 2008 μέχρι τον Απρίλιο του 2012 χωρίστηκαν σε δύο ομάδες. Στους ασθενείς της ομάδας Α πραγματοποιήθηκε η κλασσική ριζική προστατεκτομή ενώ οι ασθενείς της ομάδας Β υποβλήθηκαν στην τροποποιημένη χειρουργική επέμβαση. Τα ογκολογικά αποτελέσματα αξιολογήθηκαν με την παρακολούθηση του PSA και τον έλεγχο βιοχημικής υποτροπής καθώς και με την ύπαρξη θετικών χειρουργικών ορίων. Η μετεγχειρητική ακράτεια εκτιμήθηκε με τον αριθμό πανών/ημέρα καθώς και με τη συμπλήρωση των ερωτηματολογίων ICIQ-SF και IIQ-SF. Η μετεγχειρητική στυτική δυσλειτουργία εκτιμήθηκε με τη συμπλήρωση των ερωτηματολογίων IIEF και SEAR. Επίσης καταγράφηκε και αναλύθηκε η επίδραση της χειρουργικής τροποποίησης στην εμφάνιση μετεγχειρητικών συμπτωμάτων αποθήκευσης των ούρων.Αποτελέσματα: Ογδόντα πέντε ασθενείς εξαιρέθηκαν από τη μελέτη. Από τους 244 ασθενείς που πληρώσουν τα κριτήρια εισόδου, στην ομάδα Α και Β συμπεριλήφθηκαν 115 (47,1%) και 129 (52,9%) ασθενείς, αντίστοιχα. Δεν παρατηρήθηκαν στατιστικά σημαντικές διαφορές στα ποσοστά εμφάνισης θετικών χειρουργικών ορίων (p=0,562) και βιοχημικής υποτροπής (p=0,321). Παρατηρήθηκαν σημαντικά υψηλότερα ποσοστά ακράτειας (p=0,026), επιτακτικότητας (p<0,001) και νυκτουρίας (p<0,001) στους ασθενείς της ομάδας Α στον 1ο μήνα μετεγχειρητικά. Επίσης, υπήρξε στατιστικά σημαντική διαφορά στον αριθμό πανών/ημέρα υπέρ της ομάδας Β στον 1ο (p=0,037), 3ο (p=0,003) και 6ο (p=0,032) μήνα μετά το χειρουργείο. Η διαφορά αυτή, ωστόσο, εξαλείφθηκε στους 12 μήνες μετεγχειρητικά. Παρόμοια αποτελέσματα παρατηρήθηκαν με τις βαθμολογίες των ερωτηματολογίων ICIQ-SF και IIQ-SF, αναδεικνύοντας βελτιωμένα αποτελέσματα στους ασθενείς της ομάδας Β για τους πρώτους 6 μήνες. Δεν παρατηρήθηκαν διαφορές στα ποσοστά εμφάνισης μετεγχειρητικής στυτικής δυσλειτουργίας καθώς και στις βαθμολογίες των ερωτηματολογίων IIEF και SEAR.Συμπεράσματα: Η τροποποιημένη χειρουργική τεχνική με διατήρηση της ουρήθρας μέχρι το επίπεδο του σπερματικού λοφιδίου αποτελεί μία νέα τροποποίηση της κλασσικής τεχνικής, η οποία μπορεί να μειώσει το χρόνο ανάκτησης της εγκράτειας των ούρων σε ασθενείς που υποβάλλονται σε ριζική προστατεκτομή, χωρίς να μειώνει το ογκολογικό αποτέλεσμα και την πρόγνωση της νόσου

Clinical and Pathological Parameters Predicting Extracapsular Disease in Patients Undergoing a Radical Prostatectomy for Clinically Localized Prostate Cancer

To determine the epidemiological, clinical and pathological factors that can potentially predict extracapsular extension of prostate cancer in patients undergoing radical prostatectomy for clinically localized disease. We retrospectively analyzed the medical records of patients who undergone radical prostatectomy from January 2001 until November 2010. Patients age, prostate volume, PSA, PSA density, percent of cancer in prostate biopsy material, presence of cancer in biopsy cores of the right lobe or the left lobe or both lobes, Gleason summary, 1st Gleason pattern and 2nd Gleason pattern were analyzed for their predictive ability. From 187 studied patients, 44 of them (23.5%) had extracapsular disease. Multivariate analyses revealed that smaller prostate volumes and the presence of malignancy in both lobes after prostate biopsy were significant predictors for non-organ confined disease in the total population and in patients with Gleason score ≥7. Presence of malignancy in both lobes was the only significant predictive factor in patients with PSA ≤10 and in those with Gleason score ≤6. Prostate volume and positive cores for malignancy from both lobes after prostate biopsy are preoperative data that can be used for prediction of extracapsular disease. This information can be valuable in cases a nerve sparing radical prostatectomy is planned

Implication of High Grade Intraepithelial Neoplasia in Adverse Pathology after Radical Prostatectomy

The implication of high grade prostatic intraepithelial neoplasia (HGPIN) to prostate cancer aggressiveness and prognosis is conflicted. The aim of the present study was to evaluate the role of HGPIN in prediction of adverse pathology in patients undergoing a radical prostatectomy. We retrospectively analysed patients who underwent a radical prostatectomy between January 2005 and December 2010. The relationship between HGPIN and the presence of upgrade, positive surgical margins (PSM), extracapsular disease (ECD), seminal vesicle invasion (SVI) and lymph node invasion (LNI) was analysed. HGPIN predictive ability was estimated by using receiver operating characteristic curves. HGPIN was found in 160 (53.3%) specimens. A statistically significant correlation was found between HGPIN and preoperative prostate specific antigen (p=0.020) and patients’ age (p=0.025). No significant differences were found, regarding the presence of adverse pathological findings, between the patients with or without HGPIN, irrespective of the preoperative risk stratification. HGPIN did not reach significance for the prediction of upgrade, PSM, ECD, SVI and LNI. The presence of concomitant HGPIN and prostate cancer found not to be related with tumor aggressiveness in patients undergoing a radical prostatectomy and should not be considered as a parameter for the operative outcome prediction
