INTRODUCTION AND OBJECTIVES. The role of maintenance regimen following early intravesical chemotherapy after TUR of intermediate risk non-muscle invasive bladder cancer (NMI-BC) is still debated. Only few studies have been published on this topic, rarely dealing with patients receiving an early treatment. The aim of the present study is to evaluate the efficacy of one-year maintenance after a 6-week cycle of early intravesical chemotherapy.METHODS. Between May 2002 and August 2003, 482 patients with intermediate risk NMI-BC after TUR and early intravesical chemotherapy (epirubicin, 80mg/50mL) were randomized between 6-week induction cycle and induction plus maintenance with 10 monthly instillations. A written informed consent was obtained. All patients underwent cytology and cystoscopy 3-monthly for 2 years and 6-monthly thereafter.RESULTS. Treatment interruption for toxicity was required in 39 patients. Median follow-up was 48 months. Ten patients (2.5%) progressed and 117 patients (29.6%) recurred. The tumor characteristics were equally distributed between the two arms. No statistically significant difference in recurrence free survival (RFS) was detected between the two arms (p=0.43). An advantage in terms of recurrence free rate (RFR) in favor of the maintenance arm was evident only until 18 months after TUR (p=0.03). A trend for a higher benefit from maintenance in primary and multiple tumors was detected.CONCLUSIONS. The risk of tumor recurrence is significantly reduced by one-year maintenance only for 18 months after TUR in comparison with patients receiving a 6-week cycle of early intravesical chemotherapy. The disadvantages of prolonged intravesical chemotherapy should be taken into account.

As a preliminary approach to define the object of larger case-control studies, the distribution of potential risk factors coming from environmental pollution among patients affected by superficial bladder cancer (TCCB) has been analyzed. Material e Methods. The analysis included only patients affected by medium risk superficial TCCB. Forty Italian urological centres joined the study. Detailed information about age, sex, residency, employment, active and passive cigarette smoking, water resource, hair-dye use were centralized. All patients underwent TUR and early intravesical chemotherapy. The distribution of the above mentioned environmental factors was related to tumor characteristics such as multiplicity and previous natural history. Results. Until today 474 patients have been recruited, 182 (38.4%) with primary tumors and 293 (61.8%) with multiple lesions. Over 80% of the patients lived in urban areas, 20% were employed in industry at risk for bladder cancer and 8% used hair dye. Forty percent of the patients were smokers, with a median smoking period of 30 years. Bottled water was the only water resource in 42% of cases. At multivariate statistical analysis a significant correlation between tumor multiplicity and employment in industry (p<0.01) and between past natural history and period of cigarette smoking (p<0.05) was found. Preliminar/y, an interesting trend was detected for a correlation between water resource and bladder cancer in non-smoking patients. The municipal water system was the main water resource more frequently in non-smokers (75% vs 53%). This might imply a pathogenic role of water pollution and chlorination.

The diagnosis of prostate carcinoma has been monitored in Sicily and Calabria for one year. Material e Methods Twenty-seven urological centres of Sicily and Calabria joined the study. Detailed informations about age, familiarity, PSA, Gleason score and TNM stage at diagnosis were centralized between november 2001 and november 2002. Results 721 patients have been recruited. The median age was 73 years. More than 80% of the patients were older than 65 years. Median PSA was 14 ng/ml. The clinical stage at diagnosis was T1c in 33% of patients and 67% had an organ confined prostate cancer (T1-T2). Familiarity was detected in 8% of cases. Age and PSA at diagnosis in these patients were similar to those of the remaining population. However, only 18% of them had a T1 tumor, emphasizing the delay in diagnosis in these patients. Although only 10% of the patients shows at diagnosis a metastatic tumor, 29% only are fit for radical prostatectomy in according to age, PSA and stage.

BACKGROUND:Sexual function has been detected in a large sample of Italian patients affected by LUTS suggestive of BPH, by means of the ICS-Sex questionnaire. RESULTS:A number of 877 questionnaires were returned completely filled and were analyzed. Fifty percent of patients declared that their sexual life was significantly affected by their urinary symptoms. Difficulty in getting erections (58.2% of patients) and ejaculation problems (55.6%) were reported by the majority of patients, but the relevant bother was significantly different (48.3 and 33.4%, respectively). The ICS-Sex score was significantly associated with all the measures of symptoms and QoL employed in the study (IPSS and ICS-BPH). The urinary symptoms most frequently associated with sexual dysfunction were those related to incontinence. CONCLUSIONS:The QUIBUS study shows that sexual dysfunctions are commonly complained of by Italian men with LUTS and are significantly associated with urinary symptoms, in particular with urine loss. These findings support the recommendation by the 5th International Consultation on BPH to better evaluate both sexual function and incontinence symptoms in patients affected by LUTS suggestive of BPH.

Introduction: Pure squamous carcinoma (SCC) is a rare entity in western regions. The management of SCC still remains similar to that of transitional carcinoma, although it is a different entity. A retrospective review can be helpful in understanding the biological behavior of this uncommon vesical tumour.Material and Methods: Nineteen consecutive cases of pure SCC of the bladder, not related to bilharziasis or spinal cord injury, are herein reported. Fifteen patients were submitted to radical cystectomy, combined with emasculation in 1 case and unilateral nephroureterectomy in another. Partial cystectomy was performed in 1 patient and transurethral resection followed by radiotherapy in 3 more cases. Involvement of prostatic urethra and upper urinary tract was evident in 9 (47.3%) and 5 patients (26.3%), respectively. Four patients were submitted to neoadjuvant chemotherapy and 1 to presurgical radiotherapy without any objective response. Adjuvant chemotherapy was performed in 3 patients. At a mean follow-up of 52 months, 6 patients (31.5%) are alive without any evidence of disease. SCC antigen was monitored in 5 patients. The possible role of this marker in bladder SCC is discussed.Conclusions: Invasion of the upper urinary tract and prostatic urethra seems more common in SCC than in transitional cell carcinoma. Distant metastases are rare. Most patients die after attempts of locoregional control of the tumor have failed. Extensive surgery is recommended. Preoperative radiotherapy should be considered since pelvic recurrences are the leading cause of progression in squamous cell carcinoma. Copyright (C) 2000 S. Karger AG, Basel.

Objectives. To evaluate the nuclear matrix protein 22 (NMP22) test in the management of patients after transurethral resection (TUR) of recurrent transitional cell carcinoma of the bladder. Methods. The NMP22 test was performed in 137 patients: in 42 patients, a bladder recurrence was detected by cystoscopy and histologically confirmed; 95 patients were recurrence-free at cytology and cystoscopy performed at least 3 months after TUR. Results. In patients with tumoral recurrence, the mean NMP22 value was 54.8 U/mL. The false-negative rate was 28.5%. In recurrence-free patients, the mean NMP22 value was 22.8 U/mL. The specificity of the NMP22 test was 61%. Higher NMP22 mean values (29.6 versus 15.8 U/mL) were found in patients who underwent intravesical chemotherapy or immunotherapy. Conclusions. Despite its good sensitivity, the NMP22 test cannot be adopted as a routine tool in the surveillance after TUR of patients with superficial bladder cancer because of its low specificity.

Preliminary results are given of the topical endovesical use of idarubicin for superficial bladder urotheliomas. Its toxicity toward the urothelium is underlined; a fact which strongly compromises its endovesical chemotherapeutic use.

A case of unusual appendiceal pathology presenting as an advanced bladder cancer is reported. The difficulties in clinical and radiological diagnosis are emphasized. Correct diagnosis was possible only upon surgical exploration.
