Liu Y, Medlege HB, Kang Y, Wu L, Yang W, Zhang Y, Tian Y. Clinical efficacy of a new therapeutic option for lower genital tract lesions: 5-ALA photodynamic therapy. Lasers Med Sci 2024; 39:172. [PMID: 38965092 DOI: 10.1007/s10103-024-04129-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 06/26/2024] [Indexed: 07/06/2024]
Abstract
The study utilized 5-ALA-PDT to treat patients with CIN or VaIN and assessed their clinical response, HPV clearance, and influencing factors after photodynamic therapy (PDT). This study involved 56 patients who received 5-ALA-PDT in a single center from May 2020 to March 2022, including 12 patients with CIN, 30 patients with VaIN, and 14 patients with both CIN and VaIN. Follow-up were conducted within 6 and 12 months after treatment to evaluate the clinical effectiveness of PDT. The assessment criteria included histological response (ER, elimination rate, RR, regression rate) and HPV clearance. Additionally, factors that could potentially influence the outcomes were analyzed. After PDT, the histological response showed an ER of 48.2% (27/56) and a RR of 80.4% (45/56) within 6 months of follow-up. The elimination rate increased to 69.6% (39/56) within 12 months, along with a regression rate of 82.1% (46/56). The rates of HPV clearance were observed to be 37.5% (21/56) and 44.6% (25/56) within 6 and 12 months, respectively. The study also revealed that HPV clearance significantly influenced histologic elimination within 6 months (p < 0.001) and histologic regression within 12 months (p < 0.01). Furthermore, premenopausal women exhibited a higher HPV clearance rate compared to postmenopausal women (61.5% vs. 30.0%, p = 0.036). 5-ALA PDT can be considered as an available option for the treatment of lower genital squamous intraepithelial lesions. The efficacy of its histologic response depends on HPV clearance. Additionally, it has been found that premenopausal women may benefit more from this treatment.

Abstract
BACKGROUND Prevention of high-risk HPV (HR-HPV) infection and effective medical intervention of persistent HPV infection and precancerous lesions are critical for the prevention of cervical cancer. AIMS The aim of this retrospective comparative study was to evaluate the outcomes of ALA PDT and observation only in the management of low-grade squamous intraepithelial lesions (LSIL). METHODS In PDT Group (n = 138), ALA PDT was applied to patients with colposcopic biopsy confirmed cervical LSIL accompanied with HR-HPV infection longer than 1 year or HPV 16/18 subtype infection. Cervical LSIL only patients received 3 times of ALA PDT and those with concurrent cervical canal or vaginal lesions received 6 times ALA PDT. Control Group (n = 69) received observation only. Colposcopy, TCT and HPV typing were performed before and after treatment. Patients were followed up for up to two years. RESULT The observation group showed 26.1%, 34.8% and 53.6% HR-HPV negative conversion at 3-6, 12 and 24 months, respectively. LSIL regression rate of the observation group was 33.33%, 36.23% and 65.22% at 3-6, 12 and 24 months, respectively. There was 62.32%, 80.56% and 89.22% patients achieved HPV clearance at 3-6, 12 and 24 months after PDT treatment, respectively. The LSIL remission rate was 89.86%, 94.40% and 96.08% at 3-6, 12 and 24 months after ALA PDT, respectively. The abnormal TCT (≧ ASCUS) was reduced from 92% to 10.1%, 4.6% and 3.9% at 3-6, 12 and 24 months after ALA PDT, respectively. The patient age was not a factor affecting the clearance of HPV infection and the LSIL regression rate of PDT treatment. CONCLUSIONS This study demonstrates that the application of multiple ALA PDT treatments has added value in achieving both short-term and long-term HPV and lesion clearance.

Abstract
Persistent HPV infections may cause cervical and vaginal intraepithelial neoplasia (CIN and VaIN). Traditional methods might destroy the structure and function of the cervix. 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a non-invasive targeted therapy. This study aims to evaluate the efficacy and safety of ALA-PDT for CIN and VaIN and the clearance of HPV. A retrospective study of 303 patients who confirmed CIN or VaIN and received ALA-PDT was conducted. All the patients were followed up at six and twelve months after treatment and then annually thereafter. The effect was evaluated through HPV genotyping, a cytology test, and colposcopy-directed biopsy if necessary. After ALA-PDT, the remission rates for CIN 2, CIN 3, VaIN 2, and VaIN 3 were 90.6%, 88.5%, 87.3%, and 77.8%. For CIN 1, the remission rate at the six-month follow-up was 93.1%. The total HPV clearance rates were 72.5% at the six-month follow-up and 85.7% at the 12-month follow-up. The most common adverse event was vaginal discharge. No severe adverse effect was observed. ALA-PDT is an effective and safe treatment for all grades of CIN and VaIN and is helpful in clearing HPV with minimal side effects. This treatment may not influence fertility and delivery.

Abstract
Background Cervical cancer poses a considerable worldwide health issue, where infection with the human papillomavirus (HPV) plays a vital role as a risk factor. Photodynamic therapy (PDT) is a minimally invasive treatment for HPV-related cervical lesions, which uses photosensitizers and light to selectively destroy abnormal cells. Objectives Our objective is to present a comprehensive overview of the different types of molecules employed in PDT to reduce the occurrence and fatality rates associated with cervical cancer. Design Scoping review and bibliometric analysis. Methods The article explores clinical trials investigating the efficacy of PDT in treating low-grade squamous intraepithelial lesion and high-grade squamous intraepithelial lesion, as well as preclinical approaches utilizing various molecules for PDT in cervical cancer. Furthermore, the article sheds light on potential molecules for PDT enhancement, examining their properties through computer modeling simulations, molecular docking, and assessing their advantages and disadvantages. Results Our findings demonstrate that PDT holds promise as a therapeutic approach for treating cervical lesions associated with HPV and cervical cancer. Additionally, we observe that the utilization of diverse dye classes enhances the anticancer effects of PDT. Conclusion Among the various molecules employed in PDT, functionalized fullerene exhibits a notable inclination toward overexpressed receptors in cervical cancer cells, making it a potential candidate for intensified use in PDT. However, further research is needed to evaluate its long-term effectiveness and safety.

Abstract
Objective To determine the effectiveness and safety of 5-aminolevulinic acid mediated photodynamic therapy (5-ALA PDT) in HR-HPV infected patients with cervical low-grade squamous intraepithelial lesions (LSIL) and to explore possible factors affecting treatment outcomes. Methods This retrospective study included 96 patients with histologically confirmed cervical LSIL and high-risk human papillomavirus (HR-HPV) infection. They received 5-ALA PDT treatment once a week for a total of 3 courses. All patients were evaluated by cytology tests, HPV DNA assay, colposcopy, and biopsy at 2 weeks, 3 months, and 6 months checkpoint. The chi-square test were used to evaluate the differences in various clinical data, and a p value <0.05 was considered statistically significant. Results At 2 weeks, 3 months, and 6 months checkpoint, colposcopies showed that the cervical iodine-unstained area under VILI (visual inspection with Lugol's iodine) significantly reduced (p < 0.01) with no structure changes. At 3 months and 6 months checkpoint, the pathological regression rate reached 87.5% (84/96) and 94.79% (91/96), while the HR-HPV clearance rates reached 80.21% (77/96) and 93.75% (90/96) respectively. We also examined the efficacy in the HPV 16/18-related group and non-HPV 16/18-related group. The HR-HPV clearance rate in the HPV16/18 group [94.87% (37/39)] was significantly higher than that of the non-HPV 16/18 group [70.17% (40/57)]. However, at 6 months after treatment, the clearance rate of the HPV 16/18 group [94.87% (37/39)] showed no statistical difference from the non-HPV 16/18 group [92.30% (53/57)]. Conclusion Topical 5-ALA PDT can effectively eliminate HR-HPV infection and treat low-grade cervical squamous intraepithelial lesions, it offers an alternative treatment option for patients with LSIL, especially for those with fertility requirements and who wish to preserve cervical structure or function.

Abstract
BACKGROUND AND AIMS Low-grade squamous intraepithelial lesion (LSIL) is one of two categories of cervical intraepithelial lesions. Given that controversy exists regarding its management, this comparative study aimed to evaluate the effect of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in treating LSIL of the high-risk human papillomavirus (HR-HPV)-infected cervix. METHODS A total of 218 patients (25-45 years old) with cervical LSIL associated with HR-HPV who underwent ALA-PDT, loop electrosurgical excision procedure (LEEP), or observation only were included. The clearance rates of cervical LSIL and HR-HPV between the ALA-PDT, LEEP, and observation groups were compared at 6 and 12 months follow-up. Adverse reactions were also compared. The factors affecting the clearance on ALA-PDT of cervical LSIL were evaluated. RESULTS There were no statistically significant differences in lesion and HR-HPV clearance rates between the ALA-PDT and LEEP groups at 6 and 12 months. However, the lesion and HR-HPV clearance rates were significantly higher in the ALA-PDT group than that in the observation group. The adverse reaction rate was significantly lower in the ALA-PDT group than in the LEEP group. CONCLUSION For patients with cervical LSIL, the lesion and HR-HPV clearance rates after ALA-PDT were close to those after LEEP and significantly higher than in the observation group. Moreover, the adverse reaction rate for ALA-PDT was much lower than that for LEEP. Therefore, ALA-PDT provides a new option for the minimally invasive treatment of cervical LSIL.

Abstract
BACKGROUND Vulvar squamous intraepithelial lesion (SIL) is a precursor lesion of vulvar squamous cell carcinoma. The current clinical treatments for vulvar SIL cause damage to the vulvar structure, chronic pain and psychological distress. Topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a novel, non-invasive therapy for intraepithelial lesions. The objective of this study was to compare the clinical efficacy and safety of ALA-PDT with local surgical resection for vulvar SIL. METHODS A total of 56 patients with vulvar SIL were enrolled in this retrospective study. Among them, 16 patients received local resection and 40 patients received ALA-PDT. HPV genotyping and ThinPrep cytologic test (TCT) were used to evaluate treatment efficacy. In addition, colposcopy-directed biopsy was performed in all patients at 3-month follow-up and in patients with positive high-risk human papillomavirus (HR-HPV) and/or abnormal TCT results during the follow-up. RESULTS At 3-month follow-up and in HSIL group the complete remission (CR) rate of the ALA-PDT group and surgery group was 90.6% (29/32) and 87.5% (14/16) (P = 1.000), respectively. The HPV clearance rate of the ALA-PDT group and surgery group was 45.2% (14/31) and 43.8% (7/16) (P = 0.927), respectively. The average numbers of ALA-PDT treatments were 5.34 for HSIL patients and 4.88 for LSIL patients, respectively. The CR rate of HSIL patients and LSIL patients was 90.6% (29/32) and 75.0% (6/8) (P = 0.550), respectively. The HPV clearance rate of HSIL patients and LSIL patients was 45.2% (14/31) and 37.5% (3/8) (P = 1.000), respectively. The ALA-PDT group showed similar clinical efficacy and milder adverse effects compared with the surgical group. CONCLUSION ALA-PDT showed similar clinical efficacy as surgery in the treatment of vulvar SIL, but with milder adverse effects and maintaining the integrity of the vulvar structure.

Abstract
High-risk human papillomaviruses (HR-HPVs) cause various malignancies in the anogenital and oropharyngeal regions. About 70% of cervical and oropharyngeal cancers are caused by HPV types 16 and 18. Notably, some viruses including herpes simplex virus, Epstein-Barr virus, and human immunodeficiency virus along with various bacteria often interact with HPV, potentially impacting its replication, persistence, and cancer progression. Thus, HPV infection can be significantly influenced by co-infecting agents that influence infection dynamics and disease progression. Bacterial co-infections (e.g., Chlamydia trachomatis) along with bacterial vaginosis-related species also interact with HPV in genital tract leading to viral persistence and disease outcomes. Co-infections involving HPV and diverse infectious agents have significant implications for disease transmission and clinical progression. This review explores multiple facets of HPV infection encompassing the co-infection dynamics with other pathogens, interaction with the human microbiome, and its role in disease development.

Abstract
Cervical carcinoma (CC) is the second cause of cancer death in Mexican women. It starts with premalignant lesions known as Intraepithelial Cervical Neoplasia (CIN) that can develop due to infection by Human Papillomavirus (HPV) and other microorganisms. Current CIN therapy involves invasive methods that affect cervix integrity and fertility; we propose the use of photodynamic therapy (PDT) as a strategy with few side effects. In this work, the effectiveness of PDT for CIN I, HPV and pathogenic vaginal microbiota elimination in 29 women of Mexico City with CIN I, CIN I + HPV and HPV diagnosis was determined. After 6 months of PDT application, HPV infection was eliminated in 100% of the patients (P < 0.01), CIN I + HPV in 64.3% (P < 0.01) and CIN I in 57.2% (P > 0.05). PDT also eliminated pathogenic microorganisms: Chlamydia trachomatis in 81% of the women (P < 0.001) and Candida albicans in 80% (P < 0.05), without affecting normal microbiota since Lactobacillus iners was eliminated only in 5.8% of patients and the opportunistic Gardnerella vaginalis in 20%. These results show that PDT was highly effective in eradicating HPV and pathogenic microorganisms, suggesting that PDT is a promising therapy for cervical infections.

Abstract
Objective To evaluate and elucidate the effects and mechanism of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) on the local immune response of women with cervical intraepithelial neoplasia grade 2 (CIN2). Materials and methods Immunofluorescence staining was used to compare immune cells infiltration before and after ALA-PDT in 23 patients with CIN2. The infiltration of immune cells into the cervical tissues of patients with different outcomes was also compared at the 6-month follow-up period. Immune cell counts in samples collected before and after treatment were compared. Results We found an increased number of CD8+ T cell infiltration, an increased proportion of CD8+ T cells expressing Granzyme B (GrB), Chemokine receptor 3 (CXCR3), and CD8+ tissue-resident memory T (TRM) cells, and a decreased proportion of CD8+ T cells expressing PD-1 in patients with CIN2 compared to that before ALA-PDT. Moreover, at the 6-month follow-up, there was higher infiltration of CD8+ T and CD8+ TRM cells, higher expression of GrB and CXCR3, and lower expression of PD-1 on CD8+ T cells in the HPV clearance and CIN2 disappearance groups than in the HPV-positive and CIN2 regression groups. However, no significant difference was observed in the number of CD8+ TSCM following ALA-PDT. Conclusion ALA-PDT could activate CD8+ T cell responses by modulating the expression of CXCR3 and PD-1 in CD8+ T cells and increasing the infiltration of CD8+ TRM cells. And the infiltration of CD8+ T cells is correlated with the prognosis of CIN2.

Abstract
Cervical cancer is the fourth most common type of cancer for women in 2020, and many more women have cervical precancerous lesion-squamous intraepithelial lesion (SIL). Early treatment of cervical SIL to reverse or delay its progression is an important approach to reduce the incidence of cervical cancer. The efficacy and safety of adenovirus-based vectors expressing the thymidine kinase gene (AdV-tk) in the treatment of multiple types of cancers shows promise for its use in gynecology. We aim to provide relevant clinical efficacy and safety data after introducing AdV-tk for the treatment of cervical SIL for the first time through this prospective study. We conducted a maximum of 6 sessions to administer AdV-tk gene therapy to 23 patients (mean age: 35 years old) with cervical low-/high-grade SIL (LSIL/HSIL) who were enrolled from August 2015 to April 2018 and analyzed the clinical characteristics and follow-up outcomes (mean follow-up period: 7.3 months). The present study consisted of 17 patients (73.9%) with cervical HSIL and 6 patients with LSIL confirmed by colposcopy-directed biopsy. We observed an overall histological remission and regression rate of 87.0% (20/23, 95% confidence interval [95% CI]: 73.2-100, p < 0.001) after AdV-tk gene therapy. Eight patients (34.8%) were detected with human papillomavirus (HPV) 16/18 subtypes and 13 patients were found to be positive with at least one of the other 13 high-risk HPV (HR-HPV) subtypes, while 2 patients did not have any of the 15 HR-HPV subtypes. The overall clearance rate of HR-HPV was 76.2% (16/21, 95% CI: 58.0-94.4, p = 0.016) after AdV-tk gene therapy. For safety evaluation, no severe complications were reported in any of the 23 patients. The most commonly reported symptom was fever in 52.2% (12/23) of patients and all symptoms were fully resolved after symptomatic treatment. Our data indicate that AdV-tk gene therapy has high efficacy and safety in the treatment of cervical SIL among gynecological patients. Our findings provide clinical evidence on the potential promotion and application of AdV-tk in the treatment of cervical SIL, and potentially for cervical cancer, among gynecological patients.

Photodiagnosis Photodyn Ther 2023; 43:103721. [PMID: 37506746 DOI: 10.1016/j.pdpdt.2023.103721] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 07/09/2023] [Accepted: 07/21/2023] [Indexed: 07/30/2023]
Abstract
OBJECTIVE To evaluate the effect of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) combined with CO2 laser pretreatment (Laser+ALA-PDT) on patients with cervical high-grade squamous intraepithelial lesions (HSILs). METHODS A total of 114 patients treated by ALA-PDT or Laser+ALA-PDT at 3 centers were retrospectively reviewed. The effective rate, cure rate of lesions as well as high-risk human papillomavirus (HR-HPV) regression rate and persistent infection rate in the 2 groups were compared according to 3-6 month and 9-12 months follow-ups. The characteristics and risk factors for ineffective cases were evaluated by regression analysis. RESULTS At the 3-6month follow-up, the effective rate was significantly higher in the Laser+ALA-PDT group than in the ALA-PDT group (96.6% vs. 81.3%, p = 0.048). A total of 79.3% of the laser+ALA-PDT patients achieved cure rate compared with 61.3% of the ALA-PDT patients (p = 0.082). In the Laser+ALA-PDT group, the HR-HPV-negative rate was significantly higher (72.4% vs. 50.7%, p = 0.045), while the persistence rate was significantly lower (20.7% vs. 42.7%, p = 0.037). At the 9-12month follow-up, the cure rate was 83% in the ALA-PDT group, 17% lower than that in the Laser+ALA-PDT group (p = 0.055). A total of 20.8% of patients in the ALA-PDT group and 5.3% in the Laser+ALA-PDT group showed persistent HR-HPV infection (p = 0.120). Pretreatment HR-HPV type, multiple infections and treatment modality were relevant factors for PDT outcome. CONCLUSIONS For patients with cervical HSIL, laser+ALA-PDT shows better efficiency and HPV regression compared with ALA-PDT. HPV16/18 and multi-infection may be risk factors for ineffective treatment with ALA-PDT.

Abstract
Objective The aim of this study was to evaluate the prognostic value of Butyrophilin-like protein 8 (BTNL8) expression in high-risk HPV (hrHPV) infection treated with photodynamic therapy. Methods A total of 93 patients with hrHPV infection were enrolled as research study subjects, along with 69 healthy women who served as controls. Serum samples were obtained from each participant, and BTNL8 levels were quantified. The patients were divided into high- and low-expression groups (n = 45 and n = 48, respectively), and both groups underwent photodynamic therapy. We recorded the following data: BTNL8 expression pre-treatment and at 3/6 months post-treatment, HPV negative conversion ratio, regression rate of low-grade squamous intraepithelial lesions (LSIL), incidence of adverse reactions, complication rate, serum inflammatory factors, persistence of HPV positivity, LSIL residue or recurrence, and incidence of high-grade cervical intraepithelial lesions (HCIL). Results Patients with HPV infection exhibited higher BTNL8 expression than healthy individuals. Compared to the low-expression group, the high-expression group showed increased HPV negative conversion ratios, LSIL regression rates, and levels of IL-17 and IL-23. This group also demonstrated decreased total complication rate, HPV positivity persistence, LSIL residue or recurrence, and IL-10 levels. Additionally, there was no significant difference between the two groups in terms of the number of adverse reactions and cases with LSIL residue/recurrence. Conclusion Serum BTNL8 expression may serve as a valuable tool for early screening and prognosis monitoring of patients with hrHPV infection.

Abstract
Biofilms have become one of the fundamental issues for chronic infections, while traditional therapies are often ineffective in removing quiescent (persister) cells from biofilms, resulting in a variety of implant-related or nosocomial infections. Recently, bacteriophage (phage) therapy has reflourished in research and clinical trials. However, phage therapy alone manifested many intrinsic defects, including poor biofilm penetration, incomplete clearance of quiescent cells, etc. In this study, a phage-Chlorin e6 (Ce6)-manganese dioxide nanocomposite (PCM) was constructed by mild biomineralization. The results demonstrated that PCM contained both the vigorous activities of host bacterial targeting and efficient delivery of Ce6 to penetrate the biofilm. Assisted with NIR irradiation, robust reactive oxygen species (ROS) was triggered within the biofilm. In the weak acidic and GSH-rich infection niche, PCM was degraded into ultra-small nanosheets, endowing PCM with moderate photothermal therapy (PTT) effects and considerable Mn2+ release, thus exerting strong chemodynamic therapy (CDT) effects in situ. In vivo application demonstrated that the combination of PCM application and NIR irradiation strikingly reduced the pathogen loading, activated innate and adaptive immunity, promoted neocollagen rearrangement, and attenuated cicatricial tissue formation. Our research may pave a new way for bacterial treatment, biofilm-related infections, and other diseases caused by bacteria.

Abstract
BACKGROUND Patients after hysterectomy are at higher risk for developing VaIN. However, there are no standard treatments for HPV infection and VaIN after hysterectomy and relative studies are limited. Thus we aim to evaluate the feasibility of 5-aminolevulinic acid photodynamic therapy (5-ALA-PDT) for the treatment of persistent vaginal infection with high-risk HPV (HR-HPV) in post-hysterectomy patients. METHODS Thirty-eight patients aged 43-70 years old with persistent vaginal stump HR-HPV infection with or without histological vaginal intraepithelial neoplasia (VaIN1) during follow-up after hysterectomy were recruited. Twenty patients received three times of ALA-PDT (PDT Group). Eighteen patients did not receive any treatments (Control Group). HPV testing, cytology, and colposcopy were performed in all patients 4-6 months and 12 months after treatment. RESULTS HR-HPV remission rates of the PDT Group were 40% (8/20) and 66.67% (12/18) at the 4-6 month and 12-month follow-up, respectively, both were significantly higher than that of the Control Group (11.11% (2/18) and 6.23% (1/16), respectively; P < 0.05). For the PDT Group, the regression rate of VaIN1 was 100% (7/7) at 4-6 months, while VaIN1 recurred in two cases (28.6%) at the 12-month due to persistent HR-HPV infection. No persistence or progression of VaIN1 was noted. For the Control group, the spontaneous regression rate of VaIN1 was 50% (3/6) at 4-6 months and one patient progressed into VaIN2. At the 12-month follow-up point, one patient reccurred and the disease regression, persistence and recurrence rates were 40% (2/5), 40% (2/5) and 20% (1/5), respectively. Adverse reactions were mild after PDT treatment. CONCLUSION 5-ALA-PDT is a safe, non-invasive, and effective option for post-hysterectomy patients who have persistent HR-HPV infection.

The effect of local photodynamic therapy with 5-aminolevulinic acid in treating different grades of cervical intraepithelial neoplasia. Photodiagnosis Photodyn Ther 2022; 40:103196.

Abstract
BACKGROUND Cervical intraepithelial neoplasia (CIN) is a precursor lesion of cervical cancer. Traditional treatments for CIN might have negative effects on cervical anatomical structure and physiological function. Topical 5-aminolevulinic acid photodynamic therapy (5-ALA PDT) is a novel, non-invasive targeted therapy for intraepithelial lesions. This study aims to evaluate and compare the efficacy and safety of 5-ALA PDT for different grades of CIN. METHODS A retrospective study of 183 patients aged 19-50 with histologically confirmed CIN and receiving ALA-PDT was conducted. ALA-PDT was performed with 20% ALA thermosensitive gel and irradiation at a wavelength of 635 nm and density of 80-100 J/cm2. ALA-PDT was conducted every 7-10 days for 4-6 times. Patients were followed up three, six, nine, and twelve months after treatment. The effect was evaluated through HPV genotyping, ThinPrep cytology test (TCT), and colposcopy-directed biopsy. RESULTS The HPV clearance rate was 71.0% (130/183) at the six-month follow-up and 84.5% (147/174) at the 12-month follow-up. The complete lesion remission (CR) rate was 90.2% (165/183). No statistically significant differences concerning the CR rate (P>0.05) or HPV clearance rates (P>0.05) were observed in CIN I, CIN II, and CIN III. In women with CIN III, gland involvement was revealed to be associated with a significantly lower HPV clearance rate (63.16% vs. 92.60%, P= 0.036) at the 12-month follow-up. Our study showed that the atypical vessels seemed to be a risk factor for HPV clearance rate in the CIN II group at six-month follow-up, although the difference was not statistically significant (P= 0.089). During the follow-up, 13 cases had persistent lesions (7.1%), four cases recurred (2.3%), and none of the patients progressed. The study also showed that the efficacy of PDT in the treatment of patients with CIN III involving glands was comparable to that of CKC (P>0.05). CONCLUSIONS ALA-PDT is an effective andsafe treatment for CIN, and responseis unaffected by the grade of lesions. However, for patients with atypical vessels and glandular involvement, the effect of PDT seems to be poorer.

Abstract
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. The above patients were followed up 6 months and 12 months after PDT, and the follow-up contents included Roche Cobas HPV classification test, cytology, colposcopy, and pathological examinations. HPV negative conversion rate is an index to evaluate the efficacy of PDT. In addition, we also assessed the safety of PDT. RESULTS Six months after PDT, the overall HPV clearance rate was 59.21% (45/76). The HPV negative conversion rates in patients ≤ 50 years old group and > 50 years old group were 68.52% (37/54) and 36.36% (8/22), respectively (P=0.009). But there was no significant difference in HPV clearance rate between the HPV16/18 infection group and other hr-HPV infection group (P=0.3326). 12 months after PDT, 1 case underwent hysterectomy because of progression to HSIL, and 7 cases lost follow-up. The overall HPV clearance rate was 88.24% (60/68). The negative conversion rates of HPV16/18 and other hr-HPV infection groups were 76.00% (19/25) and 95.35% (41/43), respectively (P=0.0458). However, the HPV negative conversion rate was not correlated with the patient's age (P=0.2383). The adverse reactions after PDT were mild, mainly manifested as increased vaginal secretions or burning/tingling. CONCLUSIONS Photodynamic therapy could be an effective treatment for patients with hr-HPV persistent infection after cervical conization and it could promote the negative conversion of hr-HPV and prevent the recurrence progression of cervical intraepithelial neoplasia (CIN) after LEEP/CKC.

Abstract
OBJECTIVES To assess the efficacy and safety of focused ultrasound (FU) for high-risk human papillomavirus (HR-HPV) infection-related cervical low-grade squamous intraepithelial lesions (LSIL). METHODS Of 185 patients who met the inclusion criteria for this prospective study from October 2020 to November 2021, 95 received FU and 90 were followed up only. At the six-month follow-up, the HR-HPV clearance and LSIL regression rates of the groups were compared and factors affecting HR-HPV clearance were analyzed. The safety and side effects of FU were evaluated. RESULTS No significant difference was found in the baseline clinical data between the two groups (p > 0.05). At the six-month follow-up, the HR-HPV clearance rates were 75.6% in the FU group and 25.6% in the observation group (p = 0.000). The LSIL regression rates were 89.5% in the FU group and 56.4% in the observation group (p = 0.000). Multivariate logistic regression analysis showed that the HR-HPV clearance rate in the FU group was 9.03 times higher than that in the observation group (95% confidence interval [CI], 3.75-21.73, p = 0.000), and the clearance rate of single-type HR-HPV infections was 5.28 times higher than that of multi-type infections (95% CI, 1.83-15.23, p = 0.002). The mean intraoperative bleeding was 1.8 ± 0.6 (1-3) mL; the mean intraoperative pain score was 2.6 ± 1.0 (1-6). CONCLUSIONS For patients with HR-HPV infection-related histological LSIL, FU can eliminate HR-HPV infection and cause lesions to regress in a short time, with few adverse effects and good tolerance.

Comparative study of topical 5-aminolevulinic acid photodynamic therapy (5-ALA-PDT) and surgery for the treatment of high-grade vaginal intraepithelial neoplasia. Photodiagnosis Photodyn Ther 2022; 39:102958. [PMID: 35718105 DOI: 10.1016/j.pdpdt.2022.102958] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 05/24/2022] [Accepted: 06/07/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To compare the clinical efficacy and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) and local surgical excision in the treatment of high-grade vaginal intraepithelial neoplasia (VAIN). METHODS This was a retrospective study of a single center. Patients with biopsy-proven high-grade VAIN were counseled on the option of excision or ALA-PDT. After treatment patients were followed up at 3, 6 and 12 months and every 6 months afterwards. Clinical data of two groups were analyzed. RESULTS Sixty patients were treated with ALA-PDT and 40 patients underwent excision surgery. The clinical characteristics of patients in the two groups were similar. The mean ages of patients treated with ALA-PDT and local surgical excision were 41.93+13.08 (18-70) and 43.25+11.64 (22-61) years old, respectively. The treatment times of PDT for patients in the ALA-PDT group were 5.48±1.41 (2-8) times. At 3-6 months after treatment, the overall complete remission (CR) rate was 93.33% (56/60) in PDT group and 82.5% (33/40) in local surgical excision group. In PDT group, a 12- and 24-month follow-up, the total HPV clearance rate was 68.97% and 77.55%, respectively. At 12-month and 2-year follow-up after local surgical excision, the total HPV clearance rate was 60% and 64.52%, respectively. Further analysis showed that the clinical efficacy was comparable between the two treatments. Patients over 45 years old exhibited a lower HPV clearance rate (P<0.05) than those under 45 years old. It was also observed that persistent HPV infection is a major risk factor for persistent disease. Further comparative analyses showed no significant difference in the CR rate and treatment times between VAINII and VAINIII in ALA-PDT group. Moreover, 4 patients (11.36%) developed recurrent lesions during follow-up after ALA-PDT, whereas 3 patients (8.33%) in the local excision group developed recurrent lesions. In addition, there was no significant difference in the recurrent rate between two groups. CONCLUSIONS ALA-PDT shows similar efficacy and less side effects compared to local surgical excision.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the clinical efficacy and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in the treatment of patients with positive margin in comparison to regular follow-up, and a repeat cervical conization. MATERIALS AND METHODS A retrospective analysis was conducted using 83 patients with pathologically confirmed high-grade cervical intraepithelial neoplasia (CIN) with a positive margin after conization. The management methods and patient prognosis were analyzed and compared. RESULTS Thirty-five, 33, and 15 patients were treated for regular follow-up, ALA-PDT, and a repeat cervical conization, respectively. About 33.3% (5/15) patients had residual lesions of low-grade CIN and above after recognization. The clinical characteristics of patients in the three groups were similar. The residual lesion rates of patients selected for follow-up, ALA-PDT, and recognization were 34.3% (12/35), 9.1% (3/33), and 0% (0/15), respectively, at 6-month follow-up (p = 0.004). The HPV clearance rates were 31.3%, 66.7%, and 84.6%, respectively (p = 0.01). Further analysis showed that a positive margin in the inscribed margin of the cervical canal (p = 0.022) and persistent HR-HPV positive tests after initial conization (p = 0.003) significantly increased the risk of residual disease. At 2-year follow-up, the recurrence rates of lesions were 3.3% and 26.1% in the ALA-PDT and follow-up groups, respectively (p = 0.021). Notably, the recurrence rates were not significantly different between the ALA-PDT and recognization groups (3.3% vs. 6.7%) (p = 0.561). CONCLUSION ALA-PDT is an effective treatment for patients with a positive margin after cervical conization for high-grade CIN. Compared with regular follow-up, ALA-PDT can reduce residual and recurrence rate. Moreover, there was no significant difference in the efficacy between AlA-PDT and recognization.

Photodiagnosis Photodyn Ther 2022; 39:103009. [PMID: 35830950 DOI: 10.1016/j.pdpdt.2022.103009] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/21/2022] [Accepted: 07/08/2022] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To analyze the efficacy and safety of photodynamic therapy (PDT) on postmenopausal women with persistent human papillomavirus (HPV) infection with or without low-grade cervical and vaginal intraepithelial neoplasia (CIN1 and VaIN1). MATERIALS AND METHODS The clinicopathological and follow-up data of 86 postmenopausal women with HPV infection (35 cases with chronic cervicitis and 51 cases with CIN1/VaIN1) were collected. All the women in this group met these criteria: menopausal time ≥ 1 year, HPV infection time ≥ 2 years, colposcopy and pathological diagnosis of biopsy ≤ CIN1/VaIN1 before PDT treatment, and 5-aminolaevulinic acid (5-ALA) as photosensitizer treating for 6 times with a week interval. The above patients were followed up 6 months and 12 months after PDT treatment, and the follow-up contents included HPV typing, cytology, colposcopy and pathological examinations. HPV negative conversion rate and lesion remission rate are the evaluation indicators of treatment efficacy. In addition, we also assessed the safety of PDT treatment. RESULTS At 12-month follow-up, the overall HPV clearance rate was 60% (45/75), of which the negative conversion rate of 16/18 HPV was 41.38% (12/29), and non-16/18 HPV was 71.74% (33/46) (p = 0.009). In patients without lesions, the HPV clearance rate was 51.72% (15/29), while in patients with CIN1/VaIN1 (n = 46), the HPV complete remission rate and lesion regression rate were 65.22% (30/46) and 89.13% (41/46), respectively. In addition, the clearance rate of HPV in lesion regression group was significantly higher than that in lesion persistence/progression group (0.00% vs. 73.17%, p = 0.003). The adverse reactions after PDT treatment were mild, mainly manifested as increased vaginal secretions or burning/tingling. CONCLUSIONS Photodynamic therapy can significantly enhance the elimination rate of persistent HPV infection in postmenopausal women and reduce the progression of CIN1/VaIN1. It could be an effective conservative treatment for persistent HPV infection and CIN1/VaIN1 in postmenopausal women.

The effect of high-risk HPV E6/E7 mRNA on the efficacy of topical photodynamic therapy with 5-aminolevulinic acid for cervical high-grade squamous intraepithelial lesions. Photodiagnosis Photodyn Ther 2022; 39:102974. [PMID: 35724936 DOI: 10.1016/j.pdpdt.2022.102974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 06/16/2022] [Accepted: 06/16/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND E6 and E7 high-risk human papillomavirus (HR-HPV) oncoproteins are closely associated with the initiation and progression of cervical cancer (CC) and pre-cancerous lesions. Cervical high-grade squamous intraepithelial lesions (HSIL), as pre-cancerous lesions, have a 5% chance of progressing to invasive cancer. Topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a novel non-invasive targeted therapy for intraepithelial lesions. Herein, we analyzed the effect of HR-HPV E6/E7 mRNA on ALA-PDT for cervical HSIL. METHODS A retrospective analysis of 148 HR-HPV-positive patients diagnosed with cervical HSIL and receiving ALA-PDT was carried out. ALA-PDT was performed with 20% ALA thermosensitive gel, and irradiation at wavelength of 635 nm and density of 80-100 J/cm2 for 20-30 min. The therapeutic instruments of LED and semiconductor laser were applied for cervical lesions and lesions in endocervical canal, respectively. All patients were tested for HPV E6/E7 mRNA before and after PDT, and then followed up at 3, 6, and 12 months after treatment, and every six months thereafter. RESULTS At the 6-month follow up, the complete remission (CR) rate of patients' lesions was 86.5% (128/148), whereas the total HPV clearance rate was 72.3% (107/148). It was evident that positive E6/E7 mRNA before treatment had a significant effect on HPV clearance rate (66.3% VS 81.4%, P=0.045) and CR rate (80.9% VS 94.9%, P=0.015). The E6/E7 mRNA associated with HPV16/18 and HPV16/18 combined with other HR-HPV (HPV16/18 and other HR-HPV) affected HPV clearance (P=0.035) and lesions CR (P=0.039), respectively. Moreover, persistently positive E6/E7 mRNA after treatment was closely associated with poor efficacy (HPV clearance rate: P=0.000, CR rate: P=0.000). Throughout the follow up period, two cases recurred but none of the patients progressed. CONCLUSIONS This study has shown that ALA-PDT is an effective, safe, and alternative treatment for cervical HSIL, especially for the patients of childbearing age. However, its efficacy is relatively poor in patients with persistently positive E6/E7 mRNA before and after treatment, who are insensitive to ALA-PDT.

Abstract
BACKGROUND Lesions in both the cervix and vagina require an efficacious non-invasive treatment therapy such as 5-Aminolevulinic acid photodynamic therapy(5-ALA-PDT). In this study, we evaluate clinical efficacy and safety of 5-ALA PDT for cervical intraepithelial neoplasia with vaginal intraepithelial neoplasia (CIN & VAIN). METHODS A retrospective analysis was performed on 48 patients diagnosed with CIN & VAIN and receiving 5-ALA PDT. All patients were first followed up at 3, 6 and 12 months after treatment, then every 6 months thereafter. RESULTS Out of 1051 patients referred for CIN (4.56%), 48 were diagnosed with CIN&VAIIN. The patients had statistically significant average vaginal and cervical lesion areas of 1.22 and 0.41 cm2 respectively. 4 patients were lost during follow-up. The patients' complete remission (CR) rate was 88.64% (39/44) at 3-6 months after treatment, while the total HPV clearance rate was 46.34 and 60.98% at 3- and 12-months follow-up,respectively. HPV16/18 combined with other high-risk human papillomaviruses (hrHPV) (HPV16/18 and other hrHPV) infection exhibited a lower HPV clearance rate (P = 0.006). The treatment time in high-grade intraepithelial neoplasia (HSIL) was higher than that of low-grade intraepithelial neoplasia (LSIL). Notably, atypical vessels and endocervical canal lesions involvement significantly affected 5-ALA PDT. Moreover, 5 patients had residual lesions (11.36%) during follow-up, one patient presented recurrence (2.56%), while 4 had successful pregnancy. CONCLUSIONS 5-ALA-PDT is a non-invasive, effective, and safe therapy for treating CIN & VAIN and can maintain the structural and functional integrity of target organs. However, its efficacy is relatively poor in patients with endocervical canal lesions involvement, atypical vessels, and HPV16/18 and other hrHPV infection.

The Effect of Local Photodynamic Therapy with 5-aminolevulinic acid in the Treatment of Vaginal Intraepithelial Lesions with High-Risk HPV Infection. Photodiagnosis Photodyn Ther 2022; 37:102728. [PMID: 35045350 DOI: 10.1016/j.pdpdt.2022.102728] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 12/20/2021] [Accepted: 01/14/2022] [Indexed: 01/10/2023]
Abstract
BACKGROUND Recent data has shown increased rate of vaginal intraepithelial neoplasia (VAIN) in younger individuals. Traditional VAIN treatments exert adverse effects on the anatomy and functions of the vaginas. Topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a novel, non-invasive targeted therapy for intraepithelial lesions. Here, we aimed to investigate the efficacy and safety of ALA-PDT in VAIN with high-risk HPV (HR-HPV) infection. METHODS This study enrolled a total of 82 HR-HPV-positive women diagnosed with VAIN, who were receiving ALA-PDT. The effect of ALA-PDT was evaluated using HPV genotyping and Thinprep cytologic test (TCT). Besides, colposcopy directed biopsies were performed in all patients at 3-month follow-up, and in patients with positive HR-HPV and/or abnormal TCT results during the follow-up period. RESULTS Our data showed that the HPV clearance rate was 53.7% (44/82) at 6-month follow-up and 67.1% (55/82) at 12-month follow-up. Patients with HPV16/18 combined with other HR-HPV (HPV16/18 & other HR-HPV) infection, those with a history of hysterectomy and/or older age were had significantly lower HPV clearance rate. Besides, the lesion complete remission (CR) rate was 90.2% (74/82). These results show that HPV16/18 & other HR-HPV infection was associated with significantly lower CR rates. Throughout the follow-up, 2 cases had persistent lesions (2.4%), 6 cases had partial remission (7.3%), 2 cases recurred (2.7%) but none of the patients had disease progression. CONCLUSIONS Taken together, our data showed that ALA-PDT is an effective, safe, and alternative treatment for VAIN patients with HR-HPV infection. However, the ALA-PDT efficacy was relatively poor in patients with older age, HPV16/18 & other HR-HPV infection and/or those with a history of hysterectomy.

Abstract
OBJECTIVE To evaluate the histologic response rate of high-grade squamous intraepithelial lesion (HSIL)/cervical intraepithelial neoplasia 2 (CIN2) of the cervix after photodynamic therapy (PDT) treatment in women with fertility requirements. MATERIALS AND METHODS A retrospective study was carried out comprising 31 female patients aged 20-38 years with histologically confirmed HSIL/CIN2 with high-risk human papillomavirus (hrHPV) infection. Patients were treated with three sessions of 20% 5-aminolevulinic acid (5-ALA) PDT at intervals of 7-14 days. All patients had a follow-up including cytology, HPV testing and colposcopy-directed biopsy after PDT treatment at the 6-month and 12-month follow-up points. The main outcome measure was efficacy, defined as complete histologic remission 12 months after PDT. Secondary outcomes were the remission of HPV infection and the adverse effects of PDT treatment. RESULTS At the 12-month follow-up, 21 out of 27 patients (77.78%) and 4 out of 27 patients (14.81%) showed histologic disappearance and histologic regression, respectively. Only 7.41% (2/27) patients persisted with HSIL/CIN2. In addition, no patients progressed to CIN3 or carcinoma. The total baseline HPV remission rate was 62.96% (17/27). The remission rate of HPV16/18 was statistically significant compared to the other hrHPV (57.14% vs. 100%, p = 0.016) in the group with HISL/CIN2 disappearance. Adverse events were mild, with increased vaginal secretion and abdominal pain being the most common complaints. There was no report of adverse events such as vaginal bleeding, colporrhagia, ulcer, or abdominal pain after PDT treatment. CONCLUSIONS 5-ALA-PDT shows a favorable efficacy and safety profile and represents a promising alternative to observation and surgical procedures in patients with HSIL/CIN2 who have fertility requirements.
