Detection of IGF1R, along with other receptors, including EGFR and human epidermal growth factor receptor 2 (HER2), on extracellular vesicles has been recently confirmed using an immuno-PCR assay on samples from non-small-cell lung cancer patients, suggesting the feasibility of monitoring these tumor-associated membrane receptors in liquid biopsy [97]. The gene discussed is ERBB2; the disease is non-small cell lung carcinoma.
