Abstract
A total of 538 patients with transitional cell carcinoma of the bladder with a mean follow up period of 5.8 years (range 1–25) were retrospectively analysed to see if there were any associations between blood group and grade, stage, or prognosis of the tumour. In contrast to previous findings among European and Americans, there were no significant differences among blood groups for stage, histological grade, or survival rate.
