| Abstract: | Objective To investigate cumulative results of chemosensitivity test using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl (MTT) assay in double-layer agarose. Methods A total of 2 491 patients with different kinds of cancers were enrolled in the study, in which 18 kinds of different anticancer drugs were used. A computer soft was used to get charts. ResultsThe total evaluability rate was 82.7% (2 060/2 491). Among all agents, the efficiency rates of 5-Fu, MMC, DDP, BLM and CBP were higher than the efficiency rates of others. The response rate range of different cancer in vitro sensitivity by using MTT assay in double layer agarose were from 9.2% (biliary duct) to 37.5% (malignant lymphoma). For colon and rectum cancer, 5-Fu, DDP, MMC and BLM were more sensitive than other anti-tumor agents. For breast carcinomas, ACTD and DDP were more sensitive. For gastric cancer, 5-Fu, DDP and BLM were more sensitive. For leukemia, VM-26 and HHRT were more sensitive. ACM was more sensitive to kidney and MXT and BLM were more sensitive to pancreas cancer. For Lung cancer, DDP and EPI were more sensitive. Mean true positive rate, mean true negative rate, mean sensitivity, mean specificity and mean accuracy were 44% , 92% , 72% , 77% , and 76% , respectively. Conclusion Chemosensitivity tesing using the MTT assay in a double layer agarose was a very useful reference to chem- therapy. |
