Figure 5.

Kaplan-Meir survival curves in 27 patients with clear cell renal cell carcinomas according to: A) Cytoplasmic caspase-8 expression [green line indicates high expression (moderate/strong) while blue line low expression (weak)]. B) Fuhrman's grade [green line indicates high grade (3 and 4) while blue line low grade (1 and 2)]. According to the statistical analysis, Fuhrman's grading is more significant as a prognosticator than caspase-8 cytoplasmic expression. Cum survival: probability of being a patient alive. Time (months): months since diagnosis.
