Filter by:The World Health Organization 2016 bladder tumor classification reported that the diagnosis of variant histology has increased from 6% to 33% in the last 2 decades, and there is an increasing interest in investigating the effects on disease management, treatment options, and survival outcomes in bladder tumors with variant histology. In bladder tumors, variant histology is known to be more aggressive and has a worse prognosis than pure urothelial cancer, and most cases are muscle invasive at diagnosis. Neoadjuvant cisplatin-containing combination chemotherapy is known to improves overall survival in patients with urothelial cancers. However, it is unclear whether patients with non-pure urothelial cancer (variant) histology will also benefit from neoadjuvant chemotherapy. The investigators aimed to evaluate the role of Neoadjuvant cisplatin-containing combination chemotherapy in the final treatment plan and its impact on survival in patients with bladder cancer who were diagnosed with variant histology in the radical cystectomy specimen.
In this prospective randomized controlled study, the effects of obturator nerve block (ONB) on obturator reflex, incomplete resection, perforation, tumor recurrence and progression, presence of muscle tissue in the specimen, need for second transurethral resection of bladder tumours (TURBT) and postoperative complications were investigated in patients who underwent TURBT for intermediate and high risk lateral wall non-muscle invasive bladder tumours (NMIBC).
