Serum-soluble CD95 (sCD95) levels for 72 renal cell cancer patients were si
gnificantly higher than those of 17 healthy donors. Twenty-one of 72 patien
ts had elevated (defined as more than mean of healthy donors + 2 s.d.) sCD9
5. The disease-specific survival rate was significantly lower in the elevat
ed sCD95 group. Serum sCD95 level was shown to be an independent prognostic
factor by univariate and multivariate analysis, indicating a possible sign
ificant role in determining treatment strategies.
