This article is from BMC Urology, volume 14.AbstractBackground: We evaluated the clinical outcome of low grade Ta bladder cancer followed-up for a long period using the 2004 WHO grading system. Methods: We retrospectively reviewed 190 patients with primary, low grade Ta bladder cancer. We defined worsening progression WP as confirmed high grade Ta, all T1 or Tis-concomitant CIS of bladder recurrence, upper urinary tract recurrence UTR, or progression to equal to or more than T2. The associations between clinicopathological factors and tumor recurrence as well as WP pattern were analyzed. We also evaluated the late recurrence of 76 patients who were tumor-free for more than 5 years. Results: Tumor recurrence and WP occurred in 82 43.2% and 21 11.1% patients during follow-up median follow-up: 101.5 months, respectively. WP to high grade Ta, all T1 or Tis-concomitant CIS was seen in 17 patients, and UTR and progression to equal to or more than T2 were seen in 2 and 2 patients, respectively. Multivariate analyses demonstrated that multiple tumor p
