Bladder cancer.

PURPOSE OF REVIEW: This article will review the diagnosis and management of bladder cancer at each stage, from superficial to metastatic disease with an emphasis on recent developments over the last year. RECENT FINDINGS: Bacille Calmette-Guerin is the most effective therapy for carcinoma in situ. All patients who receive intravesical therapy with bacille Calmette-Guerin should be considered for ongoing maintenance therapy. The management of muscle invasive disease in the United States centers on radical cystectomy with bilateral pelvic lymphadenectomy. Areas of research include the optimal role for bladder preservation therapy, a growing experience in centers with laparoscopy, the effect of urinary diversion on quality of life, and the optimal standard for pelvic lymphadenectomy at surgery. The role of combination chemotherapy for advanced bladder cancer continues to evolve. Many questions remain unanswered including the relative value of neoadjuvant versus adjuvant chemotherapy for locally advanced disease and optimal chemotherapy regimen. SUMMARY: The detection of bladder cancer continues to rely on direct visualization with cystoscopy. Efforts are underway to improve the utility of urinary markers and cystoscopy through fluorescence endoscopy. The management of superficial bladder cancer is based on transurethral resection of the tumor with perioperative intravesical instillation of chemotherapy strongly suggested for most patients. Risk stratifying patients with high-risk superficial bladder cancer remain a challenge and area of future research.

Inflammatory myofibroblastic tumor associated with renal cell carcinoma.

A 46-year-old man was referred for evaluation of a 13-cm renal mass. Right radical nephrectomy was performed. Pathologic evaluation revealed inflammatory myofibroblastic tumor (IMT) and renal cell carcinoma. To our knowledge, only 28 cases of IMT associated with the kidney have been reported in published studies. This is the first reported case of IMT associated with malignancy in the urogenital tract. Some investigators have suggested that biopsy-proven IMT can be managed conservatively, but the findings of this report have demonstrated the need for radical nephrectomy in this patient population to rule out associated malignancy.

Recent advances in the treatment of bladder cancer.

Bladder cancer continues to provide urologists and researchers with a clinical and scientific challenge. Several urinary markers used in the detection and screening of patients with bladder cancer are currently under investigation. Improvements in intravesical therapy are proving to help decrease both tumor recurrence and progression in patients with high-risk disease. In patients with organ-confined, node-negative bladder cancer, radical cystectomy provides excellent local control and long-term disease-free survival. The use of an extended lymphadenectomy at the time of cystectomy may yield improved prognostic information as well as a potential survival benefit. Neoadjuvant chemotherapy and less toxic combination chemotherapy regimens are offering potential improvements in patients with extravesical or nodal extension. The current methods of detection, as well as available therapeutic treatment options are reviewed.
