PTK2 and colorectal carcinoma: In few research performed in small cohorts, enhanced expression of FAK and p-FAK was noted in CRC (Yu et al., 2006; Garouniatis et al., 2013; Albasri et al., 2014), but the correlations between raised FAK expression and tumor stage, Ki-67 positivity or survival in CRC have been inconsistent in Theocharis’s study (Theocharis et al., 2003).
