The Kaplan-Meier survival analysis model indicated that the FAK expression profile (power = 1.000 for OS, power = 1.000 for MFS) and histological response to pre-operative chemotherapy (power = 0.883 for OS, power = 0.776 for MFS) were associated with both overall survival (Figure 2A–2B) and metastasis-free survival(Figure 2C–2D), however, no such association was found for gender, patient age, AJCC surgical stage, tumor location or surgical type (Table 2). Here, PTK2 is linked to neoplasm.
