e17000 Background: Bacillus Calmette–Guérin (BCG) instillation is a key therapy to manage non-muscle invasive bladder cancer (NMIBC). However, intravesical BCG therapy fails in approximately half of patients, leading to recurrence and progression. We aimed to reveal the genetic variations associated with treatment failure after intravesical BCG therapy for NMIBC. Methods: This study included 91 Japanese patients treated with BCG instillation for NMIBC. Genomic DNA was obtained from patient whole blood samples, and a genome-wide association study and genotyping for target regions were performed. The association between genetic variation and treatment failure was analyzed by genome-wide association in 44 patients as the discovery cohort. As a validation study, candidate single nucleotide polymorphisms (SNPs) were examined among 47 patients in the distinct cohort. Results: The genome-wide association study indicated 19 candidate SNPs associated with BCG failure. Consistent results were obtained in six of these SNPs in the validation cohort. Following the combinational use of validated SNPs, 2-gene (rs73520681 and rs61094339) and 4-gene (rs4250, rs11894207, rs73520681, and rs61094339) models successfully predicted treatment failure after intravesical BCG therapy. Conclusions: This study showed that several SNPs were associated with outcome after intravesical BCG therapy in a Japanese population with NMIBC. The combinational use of these SNPs may have value in clinical applications, although this should be confirmed in future studies.

Introduction: Current life expectancy in the United Kingdom is 79.2 years in men and 82.9 years in women. Average age at diagnosis of bladder cancer is 73 years, but incidence continues to rise with age. Elderly patients represent a unique cohort of patients; they often have multiple medical co-morbidities, and may have different wishes and treatment aims as opposed to younger patients. We describe our current bladder cancer practice in patients older than 85 years. Methods: A retrospective review was conducted of patients older than 85 years, first diagnosed with bladder cancer between December 2012 and June 2016. Results: A total of 102 patients were analysed from our database. Mean age at diagnosis was 88.34 years. Staging at diagnosis was: 75 non–muscle-invasive bladder cancer (NMIBC) (17 low, 13 intermediate, 45 high risk), 23 muscle-invasive bladder cancer (MIBC), and four metastatic disease. Of patients with NMIBC, 29/75 patients had a recurrence, 4/75 were upstaged, and 9/75 progressed to MIBC. Twenty-nine of 75 of the NMIBC patients declined treatment or ongoing surveillance. Overall, 53% (53/102) have died of any cause, with a mean of 2.0 years since diagnosis, 31 of bladder cancer. In NMIBC patients, 38.7% (29/102) have died of any cause since diagnosis, at a mean interval of 1.8 years following diagnosis. Conclusion: In our cohort of bladder cancer patients older than 85 years, there is a high all-cause mortality rate within a relatively short time period following diagnosis. These data should aid well-informed discussions with our elderly bladder cancer patients and their relatives when considering treatment and surveillance options. Level of evidence: Not applicable for this single centre audit.
