查询词典 tumor

In the model of tumor cells metastases with cell line A673, 10〓 tumor cells can be detected after only one ampliation with outer primers, which means we can find 1 tumor cells in 10〓 normal PBMC, and enlarged again with inner primers, 10〓 tumor cells can be detected, which means we can find 1 tumor cell in 10〓 normal PBMC. In the simulative model of tumor cells metastases with RNA, 10〓 tumor cell can be detected that is to say we can find 1 tumor cell in about 10〓 normal PBMC. In all 15 samples of 11 patients, 2 patients'EWS/FLI1 expressions were negative, no evidence of metastases was found followed up by 8 months and 30 months respectively. Semi-quantitative study was used to detect the expression level of EWS/FLI1 mRNA in the other 9 positive patients, and metastases occurred in 6 high-level expression patients in 2-24 months after the operation, no evidence of metastases in the other 3 low-level expression patients up to now.

应用A673细胞系建立的肿瘤转移模型，单独应用外引物进行一次扩增，可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；而在此基础上再次应用内引物扩增，则可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；在用RNA模拟的肿瘤细胞转移模型中，两次扩增可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞。11例患者的15份标本中，2例没有检测到EWS/FLI1 mRNA的表达，分别随访8个月和30个月，没有发现临床转移的证据；对其余9例阳性表达的病例进行半定量的研究，6例EWS/FLI1 mRNA高表达的病例，分别在术后2-24个月发生转移，而3例EWS/FLI1 mRNA低表达的病例，则至今没有发现转移的证据。
