Methods: Specimens of CA-DNA quantification from 94cases were examined by real time FQ-PCR technique and 32cases were compared with the same method after 10-daystreatment. Results: CA-DNA was found in all patients, with an averageof 4.0×10^6 copies/ul. After 10 days of treatment, the averagewas 2.1×10^5 copies/ul. There was a significant difference inthe average amount of CA-DNA before and after thetreatment. Conclusion: Real time FQ-PCR is a good method forexamining CA-DNA amount and it can direct the treatment of CA.展开更多
