Clinical and biological markers for risk-stratification of T1 high-grade non-muscle invasive bladder cancer

Purpose of review To summarize the prognostic and predictive role of current clinical and biological markers in patients with T1 high-grade (T1HG) nonmuscle invasive bladder cancer (NMIBC). Recent findings Classical clinico-pathologic markers such as age, tumor size, focality, and location as well as the presence of concomitant carcinoma in situ, lymphovascular invasion, and histological variants at the time of transurethral resection (TUR) should be used in the risk-stratification of T1HG to improve patients’ selection for early aggressive treatment. pathological T1 substaging has shown to predict disease progression and response to intravesical therapy, and should therefore be reported in the pathological assessment to improve clinical decision-making. Urinary inducible cytokines measured at different time points during Bacillus Calmette-Guerin therapy may be used to predict response to treatment, while urinary mRNA-based biomarkers may be of value to select patients for repeated TUR (reTUR). The advent of genomic classification in NMIBC and that of immune markers may improve current risk-stratification tools and pave the way toward personalized treatment. Summary The role of clinico-pathologic variables in the risk-stratification of T1HG NMIBC remains unaltered, despite insufficient. Urinary biomarkers and tissue-based immune markers hold the promise to revolutionize the paradigm of risk-stratification due to their potential role in predicting response ...
