TL;DR: Evaluated data suggest that MPDL3280A is most effective in patients in which pre-existing immunity is suppressed by PD-L1, and is re-invigorated on antibody treatment, as well as across multiple cancer types.

TL;DR: Tumours from a large cohort of patients with metastatic urothelial cancer who were treated with an anti-PD-L1 agent were examined and major determinants of clinical outcome were identified and suggested that TGFβ shapes the tumour microenvironment to restrain anti-tumour immunity by restricting T-cell infiltration.

TL;DR: It is demonstrated that tumours expressing PD-L1-positive tumour-infiltrating immune cells had particularly high response rates, and patients with UBC, who are often older and have a higher incidence of renal impairment, may be better able to tolerate MPDL3280A versus chemotherapy.

TL;DR: Atezolizumab showed encouraging durable response rates, survival, and tolerability, supporting its therapeutic use in untreated metastatic urothelial cancer.

TL;DR: Atezolizumab was not associated with significantly longer overall survival than chemotherapy in patients with platinum-refractory metastatic urothelial carcinoma overexpressing PD-L1, thus precluding further formal statistical analysis.
