ABSTRACT
AIMS:
The newer 1998 WHO/ISUP grading system for bladder transitional cell carcinoma combined grade 3 (G3) and high grade tumour subset of grade 2 (G2) of the older 1973 WHO grading system into one homogenous high grade group. We evaluated for possible differences in survival and progression between these 2 grades in pT1 bladder tumours.METHODS:
From Jan 1(st) 1991-Dec 31(st) 2003, 105 (61 G2 and 44 G3) pT1 bladder tumours fulfilled the 1998 WHO/ISUP high grade criteria. Survival and progression of these tumours were assessed.RESULTS:
Of the 44 patients with G3 tumours, 20 are alive versus 22 of the 61 patients with high grade tumour subset of G2 (P=0.04). Of the 44 patients with G3 tumours, 13 progressed versus 12 of the 61 patients with high grade tumour subset of G2 (P=0.02). In multivariate analysis, G3 was a significant predictor of tumour progression (P=0.05) and marginally non-significant predictor of poor patient survival (P=0.056).CONCLUSIONS:
A notable difference in survival and progression between high grade tumour subset of G2 and G3 is observed.
