Epidermal growth factor receptor tyrosine kinase inhibitor（ EGFR-TKI） is a kind of targeted drug for the treatment of non-small cell lung cancer（ NSCLC）

but almost all patients develop EGFR-TKI resistance. In Chinese medicine

it is believed that Yang deficiency is the leading cause of tumor

which could end up with the internal formation of cancer toxin and promote the formation of tangible excess pathogens. Clinical and experimental studies have shown that the Chinese medicine treatment based on Yang-warming method can inhibit EGFR-TKI resistance and improve the therapeutic effect of EGFR-TKI. The mechanism may be related to the regulation of miRNA gene and estrogen receptor expression

being against tumor heterogeneity and the regulation of tumor microenvironment.Therefore

Yang deficiency is the key pathogenesis of the EGFR-TKI resistance in NSCLC

and the method reinforcing Yang and suppressing Yin is the basic therapeutic way in Chinese medicine to overcome EGFR-TKI resistance.
