Abstract:
Objective To observe the sensitivity ofastrocytoma to chemotherapeutic drugs, in order to explore the drug selection using chemosensitivity testing in vitro on astrocytoma. Comparing different WHO grade astrocytoma to chemotherapeutic drugs sensitivity differences,providing the basis data for clinical treatment. Methods The astrocytoma cells were seperated and cultured in vitro from 142 tumor tissues by glioma resection, including 55 cases of low-grade astrocytoma (WHO grade Ⅰ , Ⅱ) and 87 cases of high-grade astrocytoma (WHO grade Ⅲ, Ⅳ). The proliferation inhibition and chemosensitivity of tumor cells to 11 drugs were investigated by using MTT method. Results There were 54.93% (78/142) patients recommended chemotherapeutic drug in 142 cases. The percentage was 41.82%(23/55) in the low-grade astrocytoma, and 63.22% (55/87) in the high-grade astrocytoma respectively. Teniposide,carboplatin,vincristine as the sensitive drugs were similar in different WHO grade astrocytoma. Conclusions The chemosensitivity testing could be used to filtrate sensitive drugs to clinical chemotherapy. The action is more prominent in high-grade astrocytoma than in low-grade astrocytoma. There is no difference in the choice of sensible drugs among different WHO grade astrocytoma.
