Objective:To investigate the association between the mutation of the encoding gene of class Ⅰ?茁-tubulin (TUBB) and the drug resistance of docetaxel in the treatment of non-small cell lung cancer(NSCLC). Methods:Polymerase chain reaction(PCR) and nucleotide sequencing were used to test whether mutation existed in 90 advanced NSCLC patients. Results:A mutation at the fourth ex-on of TUBB encoding sequence which encoding the 147th amino acid was found in 36 patients,but it was not significantly associated with the chemotherapy effect of decetaxel treatment for NSCLC. Conclusions:Mutation at the fourth exon of TUBB gene is not asso-ciated with the resistance of decetaxel treatment for NSCLC patients. Further investigation should be done to verify whether the struc-ture and function of tubulin would be affected by this mutation.
