5-Aminolevulinic acid-mediated photodynamic therapy (5-ALA-PDT) is a possible minimally-invasive treatment for high-grade cervical intraepithelial neoplasia (HSIL). The present study was carried out to assess the effect of 5-ALA-PDT and loop electrosurgical excision procedure (LEEP) in cervical squamous intraepithelial neoplasia (CIN2) combined with high-risk human papillomavirus (HR-HPV) infection.
In this study, 190 patients with CIN2 and HR-HPV infection were finally included. They were divided into the LEEP Group (n = 116) and PDT Group (n = 74) according to gynecologist's recommendation and patient's willingness. All patients were followed up at 4-6 months and 12 months after treatment, including HPV testing, cytology, and colposcopy examination.
(1) 4-6 months after treatment, the pathological regression rate was 97.30 % (72/74) in the PDT group and 98.28 % (114/116) in the LEEP group (P = 0.952). The HPV clearance rate was 81.08 % (60/74) in the PDT group and 80.17 % (93/116)in the LEEP group (P = 0.877). (2) 12 months after treatment, the pathological regression rate was 93.24 % (69/74) in the PDT group and 96.55 % (112/116) in the LEEP group (P = 0.486). The recurrence rate of CIN2 was 4.05 % (3/74) in the PDT group and 1.72 % (2/116) in the LEEP group (P = 0.608). The HPV clearance rate was 90.54 % (67/74) in the PDT group and 89.66 % (104/116)in the LEEP group (P = 0.843). The reinfection rate of HR-HPV was 5.41 % (4/74) in the PDT group and 1.72 % (2/116) in the LEEP group (P = 0.322). (3) The adverse reactions in the PDT Group were slightly lower than that in the LEEP Group (P = 0.4956), but the incidence of vaginal bleeding in the PDT group was lower than that in the LEEP group during follow-up.
The effectiveness of 5-ALA-PDT is similar to LEEP for CIN2 with less side effects. Therefore, 5-ALA-PDT, a non-invasive treatment, may be an effective method for CIN2 patients of childbearing age.
5-氨基酮戊酸介导的光动力疗法（5-ALA-PDT）是一种治疗高级别宫颈上皮内瘤变（HSIL）的微创治疗方法。本研究旨在评估5-ALA-PDT和环形电切术（LEEP）治疗宫颈鳞状上皮内瘤变（CIN2）合并高危型人乳头瘤病毒（HR-HPV）感染的效果。
本研究最终纳入190例CIN2合并HR-HPV感染患者。根据妇科医生的建议和患者意愿，将其分为LEEP组（n = 116）和PDT组（n = 74）。所有患者在治疗后4 - 6个月和12个月进行随访，包括HPV检测、细胞学检查和阴道镜检查。
（1）治疗后4 - 6个月，PDT组病理缓解率为97.30%（72/74），LEEP组为98.28%（114/116）（P = 0.952）。PDT组HPV清除率为81.08%（60/74），LEEP组为80.17%（93/116）（P = 0.877）。（2）治疗后12个月，PDT组病理缓解率为93.24%（69/74），LEEP组为96.55%（112/116）（P = 0.486）。PDT组CIN2复发率为4.05%（3/74），LEEP组为1.72%（2/116）（P = 0.608）。PDT组HPV清除率为90.54%（67/74），LEEP组为89.66%（104/116）（P = 0.843）。PDT组HR-HPV再感染率为5.41%（4/74），LEEP组为1.72%（2/116）（P = 0.322）。（3）PDT组不良反应略低于LEEP组（P = 0.4956），但随访期间PDT组阴道出血发生率低于LEEP组。
5-ALA-PDT治疗CIN2的疗效与LEEP相似，但副作用较少。因此，5-ALA-PDT这种非侵入性治疗方法可能是育龄期CIN2患者的有效治疗方法。
