Interestingly, renal pelvic tumors, compared with ureteral tumors, exhibited lower positive rates of five (out of seven) transcription factors, including AR (11.1% vs. 28.0%, P = 0.070) [14], ERβ (51.1% vs. 72.0%, P = 0.056) [14], GR (57.8% vs. 68.0%, P > 0.1) [14], GATA3 (35.6% vs. 66.0%, P = 0.004) [18], and ZKSCAN3 (26.7% vs. 54.0%, P = 0.012) [19]. This evidence concerns the gene GATA3 and ureter neoplasm.
