Clinical Significance of Serum Soluble T Cell Regulatory Molecules in Clear Cell Renal Cell Carcinoma

Figure 1

Cause-specific overall survival of 70 patients with clear cell renal cell carcinoma (CCRCC) stratified by the mean serum level of soluble interleukin-2 receptor (sIL-2R). Patients were divided into two groups (high and low) based upon whether the serum level of sIL-2R was above or below the mean value in all 70 patients. Cause-specific survival curves were drawn by the Kaplan-Meier method and differences of survival were examined by the log-rank test.
