Carcinoma in situ as a prognostic factor for G3pT1 bladder tumours.
G3pT1 bladder cancer has traditionally been regarded as a superficial tumour with a high risk of progression. We have studied 37 patients with initial G3pT1 bladder tumours treated between January 1981 and December 1985. They were divided into 2 groups according to the association with carcinoma in situ (Cis) at the time of diagnosis. Clinical behaviour was analysed at 5 years. The first group (without Cis) showed progression and recurrence rates similar to those of low grade, low stage bladder tumours. The second group (with Cis) had a similar rate of recurrence but their progression rate was 65%.
