Prognostic factors, pattern of recurrence and survival in a Danish bladder cancer cohort treated with radical cystectomy.

A cohort of 248 consecutive patients with bladder cancer undergoing radical cystectomy between 1992 and 98 was retrospectively followed from diagnosis until death. Prognostic factors, pattern of recurrence and survival were analysed. Pathological T and N, angiolymphatic and perineural invasion had an independent prognostic influence on survival. Patients without muscle-invasive tumour (Ta, T1) had a good prognosis, whereas patients with primarily superficial tumour progressing to muscle-invasive tumour had a significantly poorer outcome. Forty-six percent of these patients developed recurrences in the follow-up period, with a median time from recurrence to death of 5 months. The 5-year disease-specific survival for all 248 patients was 57%. Patients with pT4b or N + all died within 3 years. Patients with positive lymph nodes or T4b were not curable with cystectomy alone. Patients with advanced T or with perineural/vessel invasion are in need of improved treatment options. Patients with superficial tumours at high risk of progression should be offered early cystectomy.
