Brief summary
Non-RCT clinical trial comparing 5-ALA photodynamic therapy and CO2 laser for persistent high-risk HPV-related low-grade cervical lesions.
Detailed description
This non-randomized controlled trial aims to compare the effectiveness of two treatments, 5-aminolevulinic acid (5-ALA) photodynamic therapy and CO2 laser, for women with persistent low-grade cervical lesions associated with high-risk HPV infection lasting more than one year. The study's primary objective is to assess which treatment option yields better results. Participants in both groups will undergo specific therapeutic procedures, including 5-ALA photodynamic therapy or CO2 laser treatment. The study will analyze and compare the effects of these therapies on the regression or elimination of cervical lesions, offering valuable insights into the management of persistent low-grade cervical lesions among high-risk HPV-infected women.
Interventions
PROCEDURECO2
CO2 laser treatment is a surgical procedure that employs a high-powered carbon dioxide laser beam to precisely ablate cervical lesions. The laser is applied with a depth of 7-10mm and a width of 3-5mm beyond the lesion area in a single session. This intervention aims to address persistent low-grade cervical lesions associated with high-risk HPV infection.
