T. Yamada et al., A STUDY OF PROGNOSIS AND CLINICOPATHOLOGY OF BLADDER-CANCER TO BLOOD-GROUP TYPE OF HOST PATIENTS IN JAPAN, Scandinavian journal of urology and nephrology, 27(2), 1993, pp. 199-203
A total of 538 patients with transitional cell carcinoma of the bladde
r with a mean follow up period of 5.8 years (range 1-25) were retrospe
ctively analysed to see if there were any associations between blood g
roup and grade, stage, or prognosis of the tumour. In contrast to prev
ious findings among European and Americans, there were no significant
differences among blood groups for stage, histological grade, or survi
val rate.
