Efficacy and pregnancy outcomes of focused ultrasound for cervical high-grade squamous intraepithelial lesions

Int J Hyperthermia. 2023;40(1):2250936. doi: 10.1080/02656736.2023.2250936.


OBJECTIVE: To investigate the efficacy and adverse effects of focused ultrasound (FU) in the treatment of high-grade squamous intraepithelial lesions (HSIL) and follow up on pregnancy outcomes in patients.

METHODS: This retrospective study recruited 57 patients aged 20-40 years with cervical HSIL combined with HR-HPV infection who received FU treatment between September 2019 and April 2022. Clinical data of the patients were obtained from hospital records. HSIL cure rate and cumulative HR-HPV clearance rate were assessed after treatment. Patients were followed up on fertility and pregnancy outcomes after treatment by telephone interviews until April 1, 2023.

RESULTS: During a 6-month follow-up, the HSIL cure rate was 73.7%, and a statistical difference between CIN2 and CIN3 (75.6% vs. 66.7%, p = 0.713) was not present. HSIL -recurrence was not observed during the follow-up period, and the median follow-up duration was 12 months. The cumulative HR-HPV clearance rates at the 6- and 12-month follow-ups were 56.1% and 75.4%, respectively. The median clearance time of HR-HPV was 6 (95% confidence interval, 5.46-6.54) months. The clearance rate was higher in HPV16/18 than in non-HPV16/18 (86.7% vs. 62.9%, p = 0.038). After treatment, the successful pregnancy rate in patients with fertility intentions and spontaneous abortion rate were 73.9% and 5.9%, respectively. Preterm birth, preterm premature rupture of membranes, or low-birth-weight infants were not observed.

CONCLUSION: FU treatment can regress HSIL and accelerate HR-HPV clearance in young women of childbearing age with cervical HSIL associated with HR-HPV infection, and has no significant adverse effects on pregnancy outcomes.
