Table 1.

The distribution of samples according to the primary tumors pathologic pT-stage and FGFR3 mutation status among either N0 or N+ cases in the radical cystectomy cohort

	pTa, pT1, pTis	pT2	pT3	pT4	Total
N0
Wild type	47	93	118	48	306
Mutated	23	11	14	6	54
N+
Wild type	5	46	127	63	241
Mutated	0	0	6	7	13
Total	75	150	265	124	614

FGFR3 mutations were associated with lower pT-stage (P < 0.001) and pN0 (P < 0.001) at radical cystectomy.
