Age and sex do not affect first year recurrence in patients with non-muscle invasive bladder cancer
Introduction: Although demographic heterogeneity in the management of patients with non-muscle invasive bladder tumor (NMIBT) is an important factor, there are only minimal evidence-based recommendations that adjust for patient age and gender.

| description | Introduction: Although demographic heterogeneity in the management of patients with non-muscle invasive bladder tumor (NMIBT) is an important factor, there are only minimal evidence-based recommendations that adjust for patient age and gender. The relationship and impact of age and gender on the recurrence in NBIMT is poorly investigated and understood.Aim: The aim of the study was to evaluate the impact of age and sex on the recurrence of non-muscle invasive bladder cancer.Materials and methods: Patients treated with transurethral resection (TUR) of primary NMIBT were included in the study. Risk calculation was made according to the European Organization for Research and Treatment of Cancer (EORTC) risk tables. Prognostic factors for predicting tumor recurrence up to 5 years including age and sex were analyzed. The Mann-Whitney U test was used for comparison of non-parametric variables in independent groups. Kaplan-Meier method, with log rank (Mantel-Cox) analyses applied for comparison of mean duration of remission by sex and age, was used to calculate mean duration of remission. Results: A total of 81 patients, 68 males (mean age 59.03 years) and 13 females (mean age 58.13 years) were eligible for final analysis. Mean survival time of patients <60 years old and older was 17.3±2.1 months (13.2–21.3) and 17.9±2.8 months (12.4–23.4), respectively (p=0.6). Mean survival time was 17.3±2.1 months for females and 15.4±2.1 months for males (p=0.08). However, 1-year tumor-free rate of female patients (53.8%) was not much different from that of males (31%) (p=0.11). Although considerable difference was observed between recurrence rates of patients according to sex, it failed to reach statistical significance.Conclusions: The results of the present study suggest that the recurrence of NMIBT is not associated with age or gender.  |
