MSLN immunostaining was unrelated to overall survival in 227 bladder carcinomas (p = 0.3302; only pT ≥ 2), 593 invasive breast carcinomas of no special types (p = 0.0976), and 502 clear cell renal cell carcinomas (p = 0.3144, Figure 4). This evidence concerns the gene MSLN and clear cell renal carcinoma.
