- The use of antibiotic prophylaxis is an accepted and widely practiced feature of modern surgery. The prevention and control of infection is a priority in healthcare worldwide, and the emergence of antibiotic resistance is a global phenomenon. Hence, rational use of antibiotics is essential. We discuss the guidelines published with regard to endourologic procedures and review the limited evidence currently available. There should be subclassification of endourologic procedures based on infection risk to guide sensible use of antibiotics before surgery.

Primary seminal vesicle carcinoma detected at transurethral resection of prostate

- We present a case of primary seminal vesicle carcinoma detected at transurethral resection. The clinical presentation, radiologic findings, and pathologic features of these tumors are reviewed. Grossly, seminal vesicle carcinoma is poorly circumscribed and solid or solid/cystic and may be misinterpreted as an abscess or hemorrhage on radiologic examination. Although a definitive diagnosis often cannot be given until after complete resection, we describe the findings indicative of seminal vesicle origin, including papillary histologic architecture, sometimes with mucinous differentiation, and a characteristic immunophenotype positive for CA-125 and cytokeratin 7, but negative for prostate-specific antigen and cytokeratin 20.

- This report presents two cases of urachal signet-cell adenocarcinoma (USCA). Two men, aged 53 and 51 years, presented with haematuria. Cystoscopy showed tumours in the dome of the bladder and transurethral resection revealed signet ring cell carcinoma. They both underwent cystoprostatectomy but died of metastatic disease after 14 and 26 months. USCA is a very rare tumour with poor prognosis. Only 25 cases have been reported. The tumours have a specific gross and microscopic morphology but must be distinguished from metastases of signet ring cell originating from other sites. Immunohistochemistry is helpful for the determination of the primary site.

Should All Patients with Non-Muscle-Invasive Bladder Cancer Receive Early Intravesical Chemotherapy after Transurethral Resection? The Results of a Prospective Randomised Multicentre Study.
- 2009

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: To decrease recurrences in non-muscle-invasive bladder cancer (NMIBC), the European Association of Urology (EAU) guidelines recommend immediate, intravesical chemotherapy after transurethral resection (TUR) for all patients with Ta/T1 tumours. OBJECTIVE: To study the benefits of a single, early, intravesical instillation of epirubicin after TUR in patients with low- to intermediate-risk NMIBC. DESIGN, SETTING, AND PARTICIPANTS: In this prospective randomised multicentre trial, 305 patients with primary as well as recurrent low- to intermediate-risk (Ta/T1, G1/G2) tumours were enrolled between 1997 and 2004. Patients were randomly allocated to receive 80mg of epirubicin in 50ml of saline intravesically within 24h of TUR or no further treatment after TUR. MEASUREMENTS: The primary end point was time to first recurrence. RESULTS AND LIMITATIONS: A total of 219 patients remained for analysis after exclusions. The median follow-up time was 3.9 yr. During the study period, 62% (63 of 102) of the patients in the epirubicin group and 77% (90 of 117) in the control group experienced recurrence (p=0.016). In a multivariate model, the hazard ratio (HR) for recurrence was 0.56 (p=0.002) for early instillation of epirubicin versus no treatment. In a subgroup analysis, the treatment had a profound recurrence-reducing effect on patients with primary, solitary tumours, whereas it provided no benefits in patients with recurrent or multiple tumours. Furthermore, patients with a modified European Organisation for Research and Treatment of Cancer (EORTC) risk score of 0-2 with and without single instillation had recurrence rates of 41% and 69%, respectively (p=0.003), whereas the corresponding rates for those with a risk score of >/=3 were 81% and 85%, respectively (p=0.35). CONCLUSIONS: A single, early instillation of epirubicin after TUR for NMIBC reduces the likelihood of tumour recurrence; however, the benefit seems to be minimal in patients at intermediate or high risk of recurrence. Future trials will determine the value of early instillation in addition to serial instillations in NMIBC.

- OBJECTIVE: Patients with non-muscle-invasive bladder cancer are traditionally followed by repeat cystoscopy and urine cytology. A fluorescence in situ hybridisation technique called UroVysion((R)) (UV) is now available for clinical diagnosis of urothelial cancer cells. The aim of the present study was to compare UV analysis with routine follow-up methods. METHODS: We studied an unselected cohort of patients undergoing cystoscopy follow-ups at two Swedish centres in 2004-2005. All patients were investigated by cystoscopy, cytology, and UV assay. The UV assay was evaluated with regards to sensitivity, specificity, and positive predictive value for tumour recurrence. RESULTS: In all, 159 cases were analysed. UV had a 30% overall sensitivity for the 27 biopsy-proven recurrences and 70% sensitivity for high-risk tumours (pT1 and carcinoma in situ [CIS]). The specificity of UV was 95%. UV detected all six CIS cases in the study and was predictive in two additional patients who developed CIS within 1 yr of inclusion. Cytology was positive in four of those eight CIS cases and atypical in the other four. CONCLUSIONS: The UV assay cannot replace cystoscopy for surveillance of patients with non-muscle-invasive bladder cancer, but it may be valuable as a supplement to traditional measures for detecting CIS. Before any conclusions can be drawn regarding the efficacy of novel markers of bladder cancer, they must be studied in bladder cancer patients undergoing endoscopic surveillance.
