First-line Treatment of Metastatic Disease. Cisplatin-ineligible Patients.

More than 50% of patients with advanced urothelial carcinoma are not eligible for the standard treatment with cisplatin-based chemotherapy. In general, cisplatin-ineligible patients with metastatic urothelial cancer experience poor outcomes with standard treatment, although substantial heterogeneity exists. Baseline variables associated with poor prognosis include borderline performance status, presence of visceral metastases, liver metastases, and low hemoglobin. Although no standard treatment has been defined for cisplatin-ineligible patients, recommendations regarding carboplatin-based combination chemotherapy versus single-agent chemotherapy versus best supportive care are typically based on performance status and renal function. The clinical development of novel agents is of considerable interest.
