Long-term oncological outcomes of bladder cancer: a population-based study with a 25-year follow-up.

ABSTRACT:

Objective

To describe the oncological outcomes for patients with newly diagnosed bladder cancer, as long-term oncological outcomes and natural history of different initial subtypes of diagnoses of bladder cancer are understudied.

Patients and methods

This was a prospective, multicentre population-based cohort study, where newly diagnosed patients with bladder cancer from 1995 to 1996 in Stockholm County, Sweden were followed. The primary outcome was cancer-specific mortality (CSM), separately analysed for low-grade non-muscle-invasive bladder cancer (NMIBC Low), high-grade non-muscle-invasive bladder cancer (NMIBC High), and muscle-invasive bladder cancer (MIBC). We used cumulative incidence with competing risk to assess survival outcomes.
