ADIPOQ and renal cell carcinoma: There were no significant differences in the mean adiponectin levels in perinephric adipose tissue-conditioned medium from control individuals (living healthy donors) and patients with RCC (Table 5, S3 Table; p = 0.115), whereas mean total adiponectin in perinephric adipose tissue-conditioned medium tended to be lower in surgically-treated RCC patients with a high BMI (Table 5, S3 Table; p = 0.088, Jonckheere–Terpstra test).
