[Progress of individualized chemotherapy guided by chemosensitivity test].

In spite of receiving chemotherapy, the response of patients with cancer can be extremely variable. Chemosensitivity testing is being applied in institutes and some hospitals to improve the effects of chemotherapy. It would be useful for choosing the most effective drug and strategy for individual chemotherapy and to exclude the resistance of the tumor cells. In this way, the individualized chemotherapy can be established. Up to today, there are more than 10 approaches established for chemosensitivity testing assays, such as single cell culture assay (including MTT, MTS, ATP), nude mouse model sensitivity examination, collagen gel droplet embedded culture drug sensitivity test and histoculture drug response assay etc. This paper reviews some current methods, and their possibility for directing clinical chemotherapy.
