Overexpression of IGF1R and EGFR Genes May Worsen Lung Cancer Prognosis

The roles of the genes IGF1R and EGFR in lung cancer were examined in patients with non-small cell lung cancer (NSCLC) who had their primary tumor surgically removed. Patients whose tumors had increased expression of both IGFR1R and EGFR were more likely to experience recurrence of the cancer after a shorter amount of time and had shorter survival times after surgery. This finding suggests that concurrent overexpression of IGF1R and EGFR is a negative prognosis factor in NSCLC and may indicate patients who are more likely to benefit from novel treatments with IGF1R inhibitors.
