IGF1R gene copy number was a highly negative prognostic marker for all NSCLC patients (p = 0.037), but was even more significant in males (p = 0.015) than in females (p = 0.021).Finally, a high IGF-1 expression showed a trend as a negative prognostic marker in males (p = 0.053) but not for the whole cohort population.
