ABSTRACT
Objective To evaluate the effectiveness of cervical intraepitheliar neoplasia grade Ⅰ (CIN Ⅰ) after treated by high intensity focused ultrasound (HIFU) Ⅰ.Methods 155 CIN Ⅰ cases in treatment group started following after HIFU method,548 cases in control group started following after cervical biopsy under the colposcope.The following intermissions were 6 months,12 months,24 months,36 months,Liquid based cytological test (LCT) and hybrid captured-Ⅱ for high rate-humanpapilomavirus (HR-HPV)test were used in every following test,and if the LCT result was atypical squamous cells (ASC-US) and HR-HPV positive,or the LCT result was greater than or equal,cervical biopsy was undergone by the colposcope to make sure the CIN Ⅰ diagnosis.Results (1) The lost rates of treatment group and control group in 36 months were 18.66% and 10.22%.(2) The inversion rates in 6 months,12 months,24 months and 36 months were 77.51 %,80.38 %,86.12 % and 88.28 %,inversion cases were rose up by the treatment gradually,succession rates were 33.01 %,22.97%,9.33% and 1.44%,and descended down gradually.(3)The inversion rates in treatment group and control group increased with observation time,there were significant differences during the 6 months,12 months,24 months and 36 months (P < 0.05) ; the succession rates in treatment group and control group descended with observation time,there were significant differences during the 6 months,12 months and 24 months (P < 0.05),and there were not significant differences in the 36 months,but significant differences between treatment group's and control group s progressive rate.Conclusions No solid scar,improving lesions inversion,reducing succession rate,guarding against the canceration were the advantages of HIFU in treatment for CIN I.
