Non-metastatic muscle-invasive bladder cancer: the role of age in receiving treatment with curative intent.

On average, one in five patients with non-metastatic MIBC remained untreated. Untreated patients were generally older and had a more unfavourable prognostic profile. Untreated patients had significantly worse overall survival, regardless of age. Age alone should therefore not affect treatment decision-making. Considering the large interhospital variation, a proportion of untreated patients might be wrongfully denied life-prolonging treatment.
