Erlotinib Efficacy in NSCLC Patients with High Polysomy of Chromosome 7 and EGFR/KRas Wild-Type Tumors

Conclusion: Among the EGFR wild-type population, when analyzed separately, high polysomy of chromosome 7 was the only molecular feature conferring clear signs of sensitivity to erlotinib. Therefore, the evaluation of high polysomy of chromosome 7 could become a helpful tool to predict for the benefit from epidermal growth factors tyrosine kinase inhibitors in selected cases.
