ABSTRACT
Objective To quantitatively detect circulating DNA levels in the plasma of patients withcervical lesion and to determine the value for diagnosis of cervical lesion and cervical cancer . Methods Preoperative blood samples were collected from 53 cases of low-grade lesions, 49 cases of high-grade lesions, 44 cases of cervical invasive cancer and 70 cases of healthy women. Plasma DNA was extracted by magnetic bead method (BILATEST DNA kit). The quantity of plasma DNA was determined by duplex real-time quantitative PCR. Results Median plasma DNA level of invasive cervical cancer patients was 61. 59 mg/L (32. 06 - 162. 16 mg/L) , which was significantly higher than that of healthy women [16. 35 mg/L(11. 98 -22.71 mg/L), P 0. 05). Median plasma DNA level of stage I patients was lower than that of stage Ⅱ- Ⅲ patients (46. 02 versus 71. 35 mg/L, P <0. 05). Conclusion Quantitatively detecting plasma circulating DNA may be with some application prospect in the diagnosis of cervical diseases.
