Abstract

Objective

To evaluate the efficacy of photodynamic therapy (PDT) for vaginal intraepithelial neoplasia grade 1 (VaIN1) related to high-risk (Hr)-human papillomavirus (HPV).

Methods

Participants aged 25–65 years treated for VaIN1 between March 2022 and September 2022 were retrospectively analyzed into three groups. The PDT and follow-up groups were matched 1:1 for gravidity, HPV type, and quadrants involved. The PDT and CO₂ laser groups were compared without matching. Patients were followed up at 6, 12, and 24 months.

Results

After matched, the lesion and Hr-HPV clearance rates of the PDT group (89.5%, 89.5%, 92.1%, and 81.6%, 84.2%, 89.5%) were significantly higher than those of the follow-up group (31.6%, 50.0%, 63.2%, and 21.1%, 26.3%, 31.6%, P < 0.05) at 6, 12, and 24 months. But the lesion clearance rates did not differ significantly between the PDT (68.9%, 82.2%, and 91.1%) and CO₂ laser groups (68.7%, 78.3%, and 85.5%, P > 0.05) at 6, 12, and 24 months, and so did Hr-HPV clearance rates (PDT as 62.2% and 77.8%, and CO₂ laser 54.2% and 61.4%, respectively, P > 0.05) at 6 and 12 months. However, at 24 months, the Hr-HPV clearance rate was higher in the PDT group than in the CO₂ laser group (86.7% vs 71.1%, P = 0.047). In the PDT group, none of the lesions progressed.

Conclusions

Compared with CO₂ laser, PDT resulted in a higher Hr-HPV clearance, as well as a low risk of complications and disease progression. PDT is an effective and noninvasive treatment for VaIN1.

光动力疗法对阴道上皮内瘤变1级的影响：一项回顾性队列研究。

目的：评价光动力疗法（PDT）治疗高危（Hr）人乳头瘤病毒（HPV）相关阴道上皮内瘤变1级（VaIN1）的疗效。方法：回顾性分析2022年3月至2022年9月期间接受VaIN1治疗的25-65岁参与者，分为三组。PDT组和随访组在妊娠、HPV类型和涉及的象限方面按1:1匹配。PDT组与CO2激光组进行不匹配比较。随访时间分别为6、12、24个月。结果：配对后，PDT组6、12、24个月病变清除率和Hr-HPV清除率（89.5%、89.5%、92.1%、81.6%、84.2%、89.5%）显著高于随访组（31.6%、50.0%、63.2%、21.1%、26.3%、31.6%），P2激光组（68.7%、78.3%、85.5%，P>0.05）， 6、12个月Hr-HPV清除率（PDT组62.2%、77.8%，CO2激光组54.2%、61.4%，P>0.05）显著高于PDT组（P >0.05）。然而，在24个月时，PDT组的Hr-HPV清除率高于CO2激光组（86.7% vs 71.1%， P=0.047）。在PDT组中，没有任何病变进展。结论：与CO2激光相比，PDT导致更高的Hr-HPV清除率，并发症和疾病进展的风险较低。PDT是一种有效的无创治疗VaIN1的方法。
