The first three drugs classified by 5 types were traditional Chinese drugs (TCM, 28.50%), other therapy (24.91%), and etiological treatment (22.23%). c) For etiological treatment, tyrosine kinase inhibitors (TKI) accounted for 59.96%, and the first three drugs were gefitinib, recombinant human endostatin, and erlotinib. d) For symptomatic treatment, analgesic drugs accounted for 43.65%; and the first three drugs were tramadol hydrochloride sustained-release tablets, sodium zoledronic oxycodone, and acetaminophen. e) For ADR therapy, liver drugs accounted for 40.97%; and the first three drugs were palonosetron hydrochloride, licorice, and diammonium pantoprazole. f) Other treatment involved immunopotentiating drugs and hematopoietic growth factors, the ratios were 62.65% and 37.35%, and the first three drugs were thymalfasin, thymopentin, and recombinant interleukin-11. g) Huisheng, Banao capsule and Bailing capsule were at the first three usage in TCM, the ratios of which were 51.06%, 15.37%, and 13.91%. h) The top ten drugs were Huisheng oral liquid, gefitinib and thymus AFP, thymopentin recombinant interleukin-11, chelating compound spot capsules, recombinant human endostatin, tramadol hydrochloride extended release tablets, sodium, zoledronic, and Bailing capsule.CONCLUSION: The antitumor therapies were mainly TKI single drug regimen for over-60-year outpatients with lung cancer in the West China hospital of Sichuan University in 2011. The most frequently used adjuvant therapies are antalgic, antitussive and skeletal related events prevention drugs. Besides, Chinese patent medicines are in common use as well.
