title: [Study on urinary levels of interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha in patients with renal cell carcinoma].
abstract: We examined the preoperative and postoperative, urinary levels of the cytokines, interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) in 14 patients with renal cell carcinoma (RCC), and 9 patients who underwent nephrectomy as donors (controls). Although urinary IL-1 beta was measurable in every subject, both IL-6 and TNF-alpha were undetectable in 12 of the 14 patients. None of the urinary cytokines showed levels significantly different from the controls preoperatively. Urinary levels of IL-1 beta showed no correlation with clinical stage or histological grade. Only urinary IL-1 beta was significantly elevated after nephrectomy, when compared with the controls (P < 0.05). However, urinary IL-1 beta showed no correlation with operative blood loss or postoperative infection. These findings suggest that measurement of urinary cytokines is not useful for diagnosis or monitoring of therapy in RCC patients.
