Previous studies have found that serum level of IL-10 was significantly elevated in urologic cancer, and it was closely correlated with tumor progression and metastasis (Stearns et al. 1999; Uwatoko et al. 2002; Dwivedi et al. 2015a, b), which suggested that IL-10 may play a vital role in the development of urologic cancer. Here, IL10 is linked to neoplasm.
