The invention discloses application of an anti-PDCD4 (Programmed Cell Death 4) antibody in preparation of a detection reagent for predicting personalized medicine sensitivity of paclitaxel or a derivative drug of paclitaxel. The variation of protein abundance of whole cells in tumor cells treated by paclitaxel is analyzed by using a quantitative proteomics technology, the results shows that paclitaxel reduces the expression level of PDCD4 and the sensitivity of the tumor cells to paclitaxel is in positive correlation with the expression level of PDCD4 in cells.
