The invention discloses an in-vitro individualized medicine test method for lung cancer and a culture medium, and belongs to the field of cell biology and pharmacology. The in-vitro individualized medicine test method and the culture medium have the advantages that the culture medium M can be applied to normal epithelial cells and primary tumor cells of human or mammals, accordingly, in-vitro culture systems for tumor cells and para-carcinoma cells of lung cancer patients can be established, and primary cells, with continuous passage and quick proliferation functions, of patient individuals can be obtained; the culture systems can be used for detecting the sensitivity and the safety of medicines or combination groups of the medicines, and accordingly stable, accurate and reliable lung cancer individualized treatment-medicine sensitivity test standard detection process systems can be established; individualized sensitive chemotherapy medicines or compositions screened by the aid of the lung cancer individualized treatment-medicine sensitivity test standard detection process systems can be combined with clinical medicine or relevant subjects, accordingly, clinical individualized treatment schemes can be formulated, and the in-vitro individualized medicine test method and the culture medium can ultimately serve for clinical application.
