Abstract

Context Urothelial carcinoma in situ (CIS) has a high propensity for progression. It is usually reported within the heterogeneous context of non-muscle-invasive bladder cancer (NMIBC) but warrants special consideration. Objective To review the contemporary literature on the diagnosis and management of CIS. Evidence acquisition A systematic search using broad terms to capture the diagnosis and treatment of CIS was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria. Full-text original articles, reviews, and editorials from 1966 to 2014 in English were included. References from selected articles, relevant guidelines, and conference abstracts were searched. Abstracts were excluded. Evidence synthesis A total of 1887 articles were identified, of which 120 were used in this review. Most reports were retrospective and heterogeneous in caseload. There is a lack of standardised classification of CIS. Many studies consider CIS in the context of NMIBC without a clear separation of the subset with CIS. Recent prospective phase 2 and 3 studies have improved the evidence base. Conclusions We are beginning to understand that CIS has a spectrum of biologic potential. Bacillus Calmette-Guérin immunotherapy appears superior to other intravesical agents and may alter the natural history of CIS. New imaging modalities, agents, and treatment strategies have emerged in recent years with the aim of better identification of CIS, more bladder-preserving treatments, and prevention of surgical overtreatment. Patient summary Improvements in imaging techniques combined with new bladder-preserving treatments will continue to have an impact on the outcomes of bladder carcinoma in situ.
