Treatment of Primary Tumor in Oligometastatic Prostate Cancer: An Observational Study of the Turkish Urooncology Association Prostate Diseases Working Group
Objective: To report the clinical results of patients who had metastatic prostate cancer (PC) at admission and underwent standard androgen deprivation therapy with radiotherapy (RT) and radical prostatectomy (RP) for the primary tumor. Materials and Methods: This study used the PC database from the Turkish Urooncology Association, to which participating institutions submit online data. The following clinical, radiological, and pathological findings were retrieved from the database: age, total prostate-specific antigen, clinical TNM stage, number of metastases, International Society of Urological Pathology grade group of biopsy, time to castration-resistant disease, type of local treatment, type of staging method, status of survival, type of systemic treatment, and follow-up time. Results: The median follow-up of the 18 included patients was 59.1 (19.9-180) months. RP and extended lymphadenectomy were performed in 12 patients. RT was performed in 6 patients. The median number of metastases was 2 (1-4) and 3 (1-4) in the RP and RT groups, respectively. In the RP group, 3 of 12 patients developed castration-resistant prostate cancer (CRPC) during the follow-up period. In the RT group, 2 of 6 patients developed CRPC in the follow-up period. The time to CRPC was 48.4 and 43.3 months, respectively. Conclusion: While primary tumor-directed RT is effective in selected patients, the results of prospective randomized controlled studies are required to demonstrate the effectiveness of RP
The value of perioperative mitomycin C instillation in improving subsequent bacillus calmette-guerin instillation efficacy in intermediate and high-risk patients with non-muscle invasıve bladder cancer: a prospective randomized study
PURPOSE: We evaluated the efficacy of perioperative mitomycin C (MMC) instillation to improve subsequent bacillus Calmette-Guérin (BCG) instillation efficacy in intermediate and high risk patients with non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: From November 2004 to May 2006, 51 patients with intermediate or high risk NMIBC were enrolled in this prospective randomized trial. In group A, patients were treated with perioperative MMC (40 mg MMC in 40 mL saline was administered within 6 hours of surgery) followed by delayed (at least 15 days from surgery) BCG instillations (once a week for 6 weeks, 5 x 108 colony-forming units in 50 mL saline). Patients in group B were treated with delayed BCG instillations alone. The primary end points were recurrence-free interval and recurrence rate. RESULTS: There were 25 and 26 patients in groups A and B, respectively. Median follow-up was 41.3 months (range 8 to 64) in group A and 40.9 months (range 6 to 68) in group B. Recurrence rate was 36% (9 of 25) and 19.3% (5 of 26) in group A and B, respectively (p = 0.052). Median time to the first recurrence was 8 months in group A and 7 months in group B (p = 0.12). CONCLUSIONS: The present study showed no statistically significant difference in terms of recurrence rate and median time to first recurrence between intermediate or high-risk patients with NMIBC who were treated with early single dose instillation of MMC plus delayed BCG and those who were treated with only BCG
Management of Patients with Urological Cancers in Turkey during the COVID-19 Pandemic: Recommendations of Uro-oncology Association
Coronavirus disease-19 (COVID-19) has been declared as a pandemic by the World Health Organization. The number of cases has increased over time in correlation with the increasing number of testing worldwide. In order to use the available resources for COVID-19 treatment, urological practice has been limited only to emergency procedures and certain uro-oncological surgeries. In this report, we aim to share our recommendations for the daily uro-oncology practice in light of local circumstances in Turkey
A survey of patient preparation and technique of ultrasound-guided prostate biopsy: A multicenter study of urooncological association
Ultrasonografî kılavuzluğunda yapılan prostat biyopsisi prostat kanseri tanısı için standart yöntemdir. Bu anketin amacı, Türkiye'deki üroloji uzmanları arasında ultrasonografî kılavuzluğunda yapılan prostat biyopsilerindeki hasta hazırlığı ve biyopsi teknikleriyle ilgili farklılıkların araştırılmasıdır. Temmuz 2004'te prostat biyopsi protokollerini sorgulamak amacıyla, Üroonkoloji Derneği Üyeleri'nin e-posta adresine bir anket formu gönderildi. Anket formundaki sorular çoktan seçmeli olup, prostat biyopsilerindeki hasta hazırlığı ve teknikleri sorguluyordu. Cevaplar yine aynı yolla toplandı ve değerlendirildi. Ankete 24 merkezden 32 üroloji uzmanı katıldı. Bu merkezlerde prostat biyopsileri sadece üroloji uzmanları (%54.16), üroloji ve radyoloji uzmanı beraber (%37.5) ve sadece radyoloji uzmanları (%8.33) tarafından yapılıyordu. Ultrasonografî kılavuzluğunda yapılan prostat biyopsileri büyük çoğunlukla transrektal yolla yapılıyordu. Merkezlerin %50'si biyopsi yapmak için PSA eşik değeri olarak 4 ng/ml'yi kullanıyordu. Biyopsi öncesi hazırlıkta bütün merkezler antibiyotik başlarken; yaklaşık yarısı bağırsak hazırlığı yapmaktaydı. Merkezlerin %37.5'i işlem sırasında analjezik kullanmazken; %29.1'i ağrıyı azaltmak için periprostatik sinir blokajı uyguluyordu. Üroloji uzmanlarının çoğu ilk biyopsilerde 10 veya 12 odaktan biyopsi alırken; %20.8'i rutin olarak transizyonel zon biyopsisi yapıyordu. Bu anket, Türkiye' deki üroloji uzmanları arasında ultrason kılavuzluğunda yapılan prostat biyopsilerinde hasta hazırlığı ve biyopsi teknikleriyle ilgili bir standardizasyon olmadığını ve bunun için bir kılavuz gerektiğini göstermektedir.Introduction: Ultrasound-guided prostate biopsy is the standard method for the diagnosis of prostate cancer. The aim of the present survey is to assess the variability in patient preparation and technique of ultrasound-guided prostate biopsy among Turkish Urologists. Materials and Methods: In July 2004, a questionnaire was sent out to e-mail addresses of the members of Urooncological Association, asking about the details of prostate biopsy protocol of the members. The survey consisted of multiple choice questions about the patient preparation and prostate biopsy technique. Responses were acquired via e-mail and analyzed in detail.Results: Thirty two urologists from 24 centers responded. The biopsy procedure was performed by the urologist only in 54.16% of the centers, both urologist and radiologist in 37.5%, and radiologist only in 8.33%. Transrectal route was the most common method for ultrasound-guided prostate biopsy. A half of the responders performed biopsy when PSA was greater than 4 ng/ml. All of the centers administered antibiotic and a half of them used enema before the procedure. Approximately 37% of responders did not administer any type of analgesia, but 29.1% of all responders administered a periprostatic nerve block for reducing painduring the procedure. Most urologists obtained 10 or 12 biopsy cores and only 20.8% of them obtained routine transitional zone biopsy during the initial biopsy session. Conclusion: This survey demonstrated that patient preparation and technique of ultrasound-guided prostate biopsy is not standardized among Turkish Urologists, and a guideline on prostate biopsy is needed
