To evaluate the efficacy of chemotherapy, immunotherapy and targeted agents with the oncogram method in patients with bladder cancer and determine the most appropriate personalized treatment agent using immune markers. Bladder cancer tissues were obtained from each patient. After cultivation, cell cultures were divided into 12 groups for each patient and 11 drugs were administered. Cell viability and immunohistochemistry expression were examined. A good response rate was determined to be a 23% viability drop. The nivolumab good response rate was slightly better in PD-L1-positive patients and the ipilimumab good response rate was slightly better in tumoral CTLA-4-positive cases. Interestingly, the cetuximab response was worse in EGFR-positive cases. Although good responses of drug groups after their application by using oncogram were found to be higher than control group, this outcome differed on a per patient basis.
