ABSTRACT
PURPOSE:
To investigate the safety, efficacy, and the immune responses of focused ultrasound in cervical intraepithelial neoplasia (CIN).METHODS:
Patients with biopsy-confirmed CIN were recruited for focused ultrasound treatment and asked to return during 3-6 and 6-12 months post-treatment to receive cervical cytology, high-risk human papilloma virus (HPV) detection, and colposcopy. The effective rate was evaluated within 3-6 months, whereas the recurrence rate was evaluated within 6-12 months. Cervicovaginal lavage and cervical tissue were sampled before and 3-6 months after treatment. The expression of interferon gamma (IFN-γ), endoplasmic reticulum aminopeptidase 1 (ERAP1), human leucocyte antigen I (HLA-I), cluster of differentiation 4 (CD4), and cluster of differentiation 8 (CD8) in the cervical tissue were observed by immunohistochemistry. Immunoglobulin A (IgA) and interleukin 10 (IL-10) levels in the cervicovaginal lavage were detected by enzyme-linked immunosorbent assay. Comparisons were made in immune analyte levels before and after treatment.RESULTS:
We analyzed the results of 154 patients. The effective rate at 3-6 months was 96.8%. The recurrence rate at 6-12 months was 2.0%. The eradication rate of HPV was 72.4% at 3-6 months and 81.0% at 6-12 months. No serious adverse reactions and complications were observed. After treatment, a higher expression of ERAP1 was observed (p < 0.05). Significant down-regulation of IgA and IL-10 were detected (each p < 0.05). However, the expression of CD4, CD8, HLA-I, as well as the release of IFN-γ, did not reach statistical significance (each p > 0.05).CONCLUSIONS:
Focused ultrasound is an effective and safe therapy for treating CIN, which could improve the local immune milieu of the cervix to some extent.Key words
