PDPN and non-small cell lung carcinoma: These findings include but are not limited to FAP expression in CAFs being related to reduced survival time in non-small cell lung cancer (NSCLC; Liao et al., 2013), podoplanin expression in CAFs related to reduced recurrence-free survival in NSCLC (Ito et al., 2012; Ono et al., 2013), PDGFRβ expression in CAFs related to reduced cancer-specific survival in breast cancer patients (Paulsson et al., 2009).
