LRIG1 is frequently down-regulated in human cancer, and high levels of LRIG1 in tumor tissue are associated with favorable clinical outcomes in several tumor types including non-small cell lung cancer (NSCLC).
LRIG1 in combination with other clinicopathological risk factors was a stronger prognostic model than clinicopathological risk factors alone.Thus, the LRIG1 expression potentially offered a significant clinical value in directing personal treatment for NSCLC patients.
LRIG1 and Fascin-1 were differently expressed in cancer and normal lung tissue in patients with NSCLC, which could be a biomarker for mediastinal lymph node metastasis in NSCLC patients.
