Abstract
TPS531 Background: Pembrolizumab leads to responses in ~20% of metastatic bladder cancer patients. Irradiation of bladder cancer cells in-vitro and in-vivo leads to upregulation of PD-L1, and in immunocompetent mouse models blockade of PD-L1 leads to delayed tumour growth following irradiation. Randomised data from PACIFIC trial in NSCLC shows the addition of PD-L1 inhibition to chemoradiation significantly prolongs PFS. A trial of chemoradiotherapy with pembrolizumab will assess safety and synergy of the combination in localised bladder cancer. Methods: This pilot study enrols patients with maximally resected non-metastatic muscle invasive bladder cancer, who either wish for bladder preser..
