Progression-free survival for SS patients diagnosed from 1980 to 2009 by levels of FGFR3 and FGFR4 expression in the tumor. Ten-year PFS curves for 47 SS patients based on high and low FGFR3 (A and B) and FGFR4 (C and D) expression. PFS was also examined after exclusion of tumors with prior exposure to radiation or chemotherapy (B and D).
