The correlation between the serum soluble interleukin-2 receptor (SIL-2R) levels and clinical stage is demonstrable in a variety of non-Hodgkin lymphomas. The prognostic significance of sIL-2R levels in the serum of patients with renal cell carcinoma (RCC) was investigated.
sIL-2R were measured in patients with RCC (n=39) and normal control (n=6) by the enzyme immunoassay technique. Cases of RCC were classified according to the clinical stage, pathological grade and growth type. The IL-2R expression of RCC was evaluated by RT-PCR.
The serum sIL-2R levels of patients with RCC showed significantly higher values than those of controls (p < 0.05). The serum sIL-2R levels in RCC were closely associated with the stage, grade and growth type of disease. The patients with high serum sIL-2R level (> = 1,000 U/L) exhibited a significantly poorer prognosis than those with low serum sIL-2R level (<1,000 U/L). The band of IL-R was detected only by using the template from the mRNA extracted from a resected tumor tissue of the RCC but not from the RCC cell lines.
It was suggested that the measurement of serum sIL-2R levels is useful for predicting the prognosis.
血清可溶性白细胞介素-2受体（SIL-2R）水平与临床分期之间的相关性在多种非霍奇金淋巴瘤中是可证实的。本研究调查了肾细胞癌（RCC）患者血清中sIL-2R水平的预后意义。
采用酶免疫测定技术检测39例RCC患者和6例正常对照者的sIL-2R。RCC病例根据临床分期、病理分级和生长类型进行分类。通过逆转录聚合酶链反应（RT-PCR）评估RCC的IL-2R表达。
RCC患者的血清sIL-2R水平显著高于对照组（p<0.05）。RCC患者的血清sIL-2R水平与疾病的分期、分级和生长类型密切相关。血清sIL-2R水平高（>=1000 U/L）的患者预后明显比血清sIL-2R水平低（<1000 U/L）的患者差。仅使用从RCC切除的肿瘤组织中提取的mRNA模板检测到了IL-R条带，而从RCC细胞系中未检测到。
提示检测血清sIL-2R水平有助于预测预后。
