Advances in the Management of Superficial Bladder Cancer

Abstract

Given its high tendency to recur, coupled with an ever-present possibility to progress to potentially life-threatening muscle-invasive disease, superficial bladder cancer remains a challenging clinical problem. Optimal management begins with early detection and accurate risk assessment through careful attention to clinical features, aided by an emerging array of urinary markers and molecular characterizations. Prevention of recurrence requires the sequential application of tools to completely remove all visible disease, avert reimplantation during surgical resection, ablate microscopic foci, and prevent the emergence of new primary tumors amidst a field of carcinogen-exposed urothelium. Previously standard adjunctive intravesical chemo- and immunotherapies are enjoying new vitality as optimization strategies, new drugs, and rational drug combinations provide the potential for improved efficacy with reduced toxicity. New technological advances such as fluorescence-aided cystoscopy, microwave chemothermotherapy, and electromotive chemotherapeutic drug delivery offer further hope for better outcomes even for disease previously refractory to conservative measures. Yet despite these advances, aggressive surgical management involving bladder removal continues to be an indispensable life-saving maneuver that must be considered in all high-risk cases that fail to promptly respond to other measures.
