Abstract
INTRODUCTION: Bladder tumor is a disease of older persons, but can also occur in young adults, because certainly an influence of environmental factors and a change of lifestyle. The aim of our retrospective analysis is to assess and evaluate the extent of the prognostic impact of age on the carcinological prognosis of invasive-muscle-bladder cancer treated by total cystotomy. METHODS: To evaluate the association of patient age with pathological characteristics and recurrence-free and disease survival, we retrospectively reviewed 345 patients with invasive bladder cancer between January 2000 and January 2015. RESULTS: We divided our patients into two groups: patients under 65 years of age=150 cases (group 1), patients aged 65 years and over=195 cases (group 2). The 3-year survival rates for patients according to the age groups were 88% and 64% respectively, end the recurrence-free survival 66% and 28%. When age was analysed as a categorical variable, was associated with hydronephrosis (P=0.001), advanced pathological stage (P=0.034), high grade (P=0.026), nodal involvement (P=0.011) and lymphovascular invasion (P=0.008). The multivariate Cox model analysis showed that hydronephrosis and pathological stage was prognostic factors of survival (P=0.012 and P=0.035, respectively). Higher age is significantly associated with the risk of pathologically advanced disease and poorer global survival. CONCLUSION: This work allowed us to assert that advanced chronological age is significantly associated with an advanced pathological stage of the disease (volume, pT, grade, lymph nodes) and a low overall survival rate. This could be useful for selecting subjects who would require adjuvant therapy, as well as for planning early complementary therapies. LEVEL OF EVIDENCE: 3.
