Prognostic Performance of a Chemogram in Patients With Bladder Cancer.

The aim of the study is to evaluate chemogram in patients with intermediate-grade superficial bladder cancer and patients with infiltrating bladder cancer, who are likely to be treated according to the standard procedure. This project is based on the premise that treatments - notably chemotherapy - are standard, but that each cancer is unique. It is therefore necessary to personalize the treatment for each patient, while at the same time proposing an approach that is economically bearable for the healthcare system. For both types of bladder tumor, chemotherapy is used either as an alternative to immunotherapy, or as an adjuvant to surgery. Its use is therefore based on its effectiveness in reducing post-treatment recurrence.
