Recurrence-free survival according to protein expression of cortactin, FADD, and Chk1. Kaplan-Meier curves showing the effect of (a) cortactin, (b) FADD, (c,d) and Chk1 expression on recurrence-free survival in the subgroup of untreated control patients. Expression of cortactin or Chk1 did not influence the recurrence rate. However, over-expression of FADD was associated with shorter recurrence-free survival compared with lower expression. Chk1, checkpoint kinase 1; FADD, Fas-associated death domain.
