The effect of age on bladder cancer incidence, prognosis and therapy

Urothelial carcinoma in first histological diagnosis of patients over 80 years has distinctive histological features: a retrospective single-institution study of 185 patients

Few histological data are known about patients with a first diagnosis of bladder cancer (BC) at the age ≥80 years. We describe the largest series in this patient group and their distinctive histological features. This unicentric retrospective study included patients at the age ≥80 years with a first diagnosis of bladder cancer between 2005 and 2015. All diagnosis was made by one senior uropathologist according to the WHO 2016 classification, pTNM 7th edition 2009. We examined samples of 185 patients, sex ratio M:W = 2.49:1, with ≥80 years at the time of first diagnosis of BC. The mean age was 85.1 years (84.8 for men and 85.8 for women). One hundred sixteen patients were diagnosed with NMIBC (non-muscle invasive bladder cancer) (62.7%). Sixty-nine patients were detected with MIBC (muscle invasive bladder cancer) (37.3%). In the MIBC, 20 (29.0%) cases, a divergent differentiation was reported. No patient had primary carcinoma in situ (Cis) at time of diagnosis, and concomitant Cis was observed in 18.9% (35 cases). According to our results, the histopathological findings are different from those of other patients' groups. The study shows a higher number of MIBC and a high percentage of histological variants. We could show distinctive pathological features in this patient group.

Comparison of Complications from Radical Cystectomy between Old-Old versus Oldest-Old Patients

Introduction: The purpose of this study was to evaluate and compare complications after radical cystectomy in patients aged ≥75 years. Materials and Methods: 251 patients aged 75-95 years (median 79) underwent radical cystectomy between 2000 and 2012 at four institutions. The patients were divided into two groups: ≥75-84 years of age (group 1) versus ≥85 years of age (group 2). Comorbidities, body mass index, and complications were obtained retrospectively, except at the Central Hospital of Bolzano and Weill Cornell Medical Center, which collected data prospectively. Cancer-specific survival, overall mortality, hospital stay, clinical outcome and complications were assessed. Complications were categorized using the Clavien-Dindo classification reporting system. The mean follow-up was 21 months. Results: The median hospital stay was 17 (2-91) days. Perioperative Clavien-Dindo grade ≥III complications were seen in 24.1% (48/199) of group 1 patients and 19.2% (10/52) of group 2 patients (p = 0.045). 30- and 90-day mortality was 4.5 and 13.5% in group 1 and 6.5 and 32.3% in group 2, respectively. Only the 90-day mortality rate was statistically significant (p < 0.05) between the two groups. The 3-year overall survival was 40% in group 1 and 34% in group 2. The 3-year cancer-specific survival was 52% in group 1 and 50% in group 2. Conclusions: We evaluated a large series of elderly (≥75 years) patients undergoing radical cystectomy at four institutions. Comparing patients aged ≥75-84 and ≥85 years revealed no significant difference in complications, 30-day mortality, overall and cancer-specific survival rates. Only 90-day mortality rates were significantly higher in the ≥85-year-old patients.
