[Prognostic of older age for patients with invasive-muscle-bladder cancer and treated by radical cystectomy]

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.

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.

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.

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.
