The purpose of this study is to assess the prevalence of pre-treatment tumor tissue PD-L1 expression in patients diagnosed with advanced urothelial carcinoma.

Advanced urothelial carcinoma (UC) (locally advanced/unresectable or metastatic UC) is a fatal disease with 5-year survival rate of 5%. The most frequently studied diagnostic for advanced UC is the programmed death-ligand 1 (PD-L1) protein expression in tumor tissue. A better understanding of PD-L1 expression in a "real world" setting could help understand its clinical utility in the management and decision making in advanced UC and clinical trial design

Inclusion Criteria:

• Provision of written informed consent
• Age ≥18 years old
• Patient must have advanced UC confirmed by their HCP; histologically- confirmed diagnosis of UC an dHCP-confirmed advanced UC.
• Patient must be either currently receiving 1L systemic treatment for their advanced UC or will be starting 1L systemic treatment (i.e. "newly diagnosed" advanced UC; 1L therapy is defined as the first systemic therapy given for advanced UC).
• Patient remains eligible for the study if they received neoadjuvant or adjuvant platinum-based chemotherapy if their recurrence was more than 12 months after their last chemotherapy dose.
• Radio-sensitizing chemotherapy as part of chemoradiation is NOT counted as neoadjuvant or adjuvant chemotherapy; thus, the 12-month interval mention above does not apply, and the patient would be eligible
• Patients with available tumor tissue sample (fresh or archival - up to 3 years old) that was collected as part of SoC any time prior to 1L treatment for advanced UC with a target of 18 slides (7 minimum) available for biomarker testing (PD-L1 and tTMB). Already prepared slides must have been cut within 6 months prior to PD-L1 testing.

Exclusion Criteria:

• Patients concurrently enrolled in other clinical trials that prohibit their participation in a non-interventional study

• Patient has resectable localized UC and has refused surgery

• Patients with history of non-urothelial active malignancy that completed therapy within 2 years from study enrollment except:

  • Any resected in situ carcinoma or non-melanoma skin cancer
  • Localized (early stage) cancer treated with curative intent (without evidence of recurrence and intent for further therapy) and in which no systemic therapy was indicated
