Article Abstract
Objectives: This review aims to compare the effectiveness of photodynamic therapy (PDT) with conization, including loop electrosurgical excision procedure (LEEP) and cold-knife conization (CKC), in treating cervical high-grade squamous intraepithelial lesions (HSIL).
Methods: PubMed, Cochrane Library, Google Scholar, Embase, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched. The outcomes assessed were complete response (CR) rate, human papillomavirus (HPV) eradication rate, recurrence rate, and adverse events (AEs).
Results: 9 studies were included. A total of 312 patients received PDT, while 380 underwent conization (LEEP/CKC). There was no significant difference between PDT and conization in the CR rate at 3-6 months (OR: 1.64 [0.97, 2.76]; P = 0.06), 12-month CR (OR: 0.49 [0.13, 1.90]; P = 0.30), HPV eradication rate at 3-6 months (OR: 1.40 [0.95, 2.07]; P = 0.09), HPV eradication rate at 12 months (OR: 0.92[0.47, 1.82]; P = 0.81), or 12-month recurrence rate (OR: 2.97 [0.62, 14.25]; P = 0.17). However, the rate of AEs, including vaginal bleeding (OR: 0.10 [0.03, 0.33]; P = 0.0002), cervical canal adhesion (OR: 0.16 [0.03, 0.90]; P = 0.04), and cervical scar formation (OR: 0.04 [0.01, 0.30]; P = 0.002), was significantly lower with PDT than with conization. The degree of heterogeneity was not high.
Conclusion: Based on our systematic review and meta-analysis, it could be concluded that PDT may be a practical approach for cervical HSIL regression compared to conization (LEEP/CKC). However, further high-quality, controlled trials are needed to confirm these findings.

Article Synopsis
- Cervical cancer is a significant health issue among young women, prompting the need for better diagnosis and treatment methods, particularly focusing on photodynamic therapy (PDT) using chlorin e6 (Ce6).
- A clinical study with 94 women evaluated the effectiveness of PDT versus traditional conization treatments, finding that those who received PDT showed greater improvement in cytological outcomes and fewer cervical lesions.
- Results indicated that patients undergoing PDT had better reproductive outcomes, demonstrating its higher clinical efficacy and safety in treating cervical preinvasive conditions compared to standard surgical treatment.

Objective: The study aimed to compare the clinical efficacy and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) and surgery in treating recurrent cervical high-grade squamous intraepithelial lesions (HSIL) after surgery due to precancerous lesions.
Methods: A total of 41 patients with recurrent cervical HSIL after surgery for precancerous lesions were studied retrospectively. Patients underwent ALA-PDT or surgery and were followed up at 3, 6, 9 and 12 months and then every six months after that.

(1) Purpose: To investigate the efficacy and safety of using PDT in the treatment of severe intraepithelial squamous lesions of the cervix and preinvasive cervical cancer associated with HPV in women of reproductive age. (2) Methods: The examination and treatment of 45 patients aged 22-49 years with morphologically confirmed HPV-associated cervical intraepithelial neoplasia of a severe degree (17 patients) and preinvasive cervical cancer (28 patients) were performed. All patients underwent PDT of the cervix using a chlorin e6 photosensitizer; after which, the affected areas of the cervix were evaluated using video and spectral fluorescence diagnostics.

Objective: To evaluate the efficacy and safety of photodynamic therapy (PDT) in women with high-risk human papillomavirus (hr-HPV) persistent infection after cervical conization, including loop electrosurgical excision procedure (LEEP) and cold knife conization (CKC).
Materials And Methods: The clinicopathological and follow-up data of 76 women with hr-HPV persistent infection after cervical conization (54 cases with LEEP and 22 cases with CKC) were collected. All the women in this group met these criteria: postoperative pathological diagnosis of LEEP/CKC showed high grade squamous intraepithelial lesions (HSIL) with negative incisal margin, hr-HPV persistent infection after LEEP/CKC ≥ 1 year, colposcopy and histopathology showed no intraepithelial lesions before PDT, and 5-aminolaevulinic acid (5-ALA) as photosensitizer treating for 6 times with an interval of 7-10 days.
