Descrizione riassuntiva dello studio

In patients with superficial bladder cancer, tumor samples are cultured and the efficacy of 4 different chemotherapeutics is tested on these personalized cultures. The drug that shows the highest efficacy in the tumor model is selected. The bladder is then irrigated on an outpatient basis 6 times at weekly intervals with the drug after surgery to prevent recurrence.

(BASEC)

Intervento studiato

The four drugs are already in clinical use for this condition, they show different efficacy and are currently used according to the urologist's preference and availability in the hospital. We wanted to test whether we could use primary cultures from superficial bladder cancer to test these chemotherapeutics. The information obtained should then help in the clinic to make a personalized decision regarding the choice of the appropriate drug.
