Like cervical cancer, anal cancer is often caused by a human papillomavirus and has a premalignant stage called high-grade squamous intraepithelial lesion or anal intraepithelial neoplasia. A randomized trial showed that treating HSIL led to a 57% reduction in progression to anal cancer as compared with active surveillance.

Background Each year, 45,000 women worldwide develop vulvar cancer, often occurred from vulvar high-grade squamous intraepithelial lesions (vHSIL), a precancerous stage associated with high- risk human papillomavirus (HPV). Recurrent vHSIL, experienced by over 30% of patients despite treatment, conducting in significant physical and psychosocial challenges. With no established method to reduce recurrence, our study investigates the potential of adjuvant HPV vaccination during treatment. We aim to determine whether nonavalent HPV vaccination can effectively prevent vHSIL recurrence in women treated for vulvar HSIL. Methods This is a randomized, double-blind, placebo-controlled study protocol involving 498 women diagnosed with vHSIL. Participants will be randomized to receive either the nonavalent HPV vaccine or a placebo in addition to standard treatment. The primary outcome is the recurrence of vHSIL within 24 months following treatment. Secondary endpoints are treatment effectiveness, immune response, cost-effectiveness, and quality of life. Long-term follow-up examines vaccine effect after 5 and 10 years, along with the occurrence of vulvar malignancies. Relative risk between vaccinated and placebo groups will be evaluated, employing intention-to-treat principles. Discussion This study is designed to investigate the potential benefits of HPV vaccination in managing vHSIL. Results from the trial will provide evidence on the vaccine’s impact on recurrence rates, treatment outcomes, and long-term prevention of vulvar malignancies. Trial registration ClinicalTrials.gov.

Purpose To determine whether treatment of anal high-grade squamous intraepithelial lesions (HSIL), vs active monitoring, is effective in reducing incidence of anal cancer in persons living with HIV, the US National Cancer Institute funded the Phase III ANal Cancer/HSIL Outcomes Research (ANCHOR) clinical trial. As no established patient-reported outcomes (PRO) tool exists for persons with anal HSIL, we sought to estimate the construct validity and responsiveness of the ANCHOR Health-Related Symptom Index (A-HRSI). Methods The construct validity phase enrolled ANCHOR participants who were within two weeks of randomization to complete A-HRSI and legacy PRO questionnaires at a single time point. The responsiveness phase enrolled a separate cohort of ANCHOR participants who were not yet randomized to complete A-HRSI at three time points: prior to randomization (T1), 14–70 (T2), and 71–112 (T3) days following randomization. Results Confirmatory factor analysis techniques established a three-factor model (i.e., physical symptoms, impact on physical functioning, impact on psychological functioning), with moderate evidence of convergent validity and strong evidence of discriminant validity in the construct validity phase ( n  = 303). We observed a significant moderate effect for changes in A-HRSI impact on physical functioning (standardized response mean = 0.52) and psychological symptoms (standardized response mean = 0.60) from T2 ( n  = 86) to T3 ( n  = 92), providing evidence of responsiveness. Conclusion A-HRSI is a brief PRO index that captures health-related symptoms and impacts related to anal HSIL. This instrument may have broad applicability in other contexts assessing individuals with anal HSIL, which may ultimately help improve clinical care and assist providers and patients with medical decision-making.

Imiquimod is a standard therapy option for vulvar high-grade squamous intraepithelial lesions (vHSIL). In a retrospective study, the pre-existing composition of the immune cell infiltrate was associated with clinical outcome after imiquimod treatment. To validate these findings, an in-depth analysis of the tumor microenvironment was performed on a vHSIL cohort treated with imiquimod in the prospective PITVIN randomized controlled trial (ClinicalTrials.gov identifier: NCT01861535). Pretreatment biopsies of per-protocol patients participating in the PITVIN trial allocated to the imiquimod arm were included (n=38). These were analyzed by multispectral immunofluorescence using two seven-color staining panels for T cell and myeloid cell composition. Samples were scanned with the Vectra imaging microscope. Cell phenotyping was conducted using semi-supervised machine learning. Quick complete response (qCR) (n=27) was defined as absence of clinical lesions at 16 weeks; slow complete response (n=4) as delayed clearance requiring treatment up to 6 months; and non-response (n=7) as persistent histological vHSIL after 6 months, necessitating extended treatment or surgery. Analysis of the tumor immune microenvironment revealed interpatient variability in immune cell infiltration. Immune infiltrate composition in primary and recurrent vHSIL was comparable and this was also reflected by their clinical responsiveness to imiquimod. Higher numbers of intraepithelial CD3+CD8-(CD4+) T helper cells CD4+FoxP3+ regulatory T cells and CD14+ inflammatory myeloid cells and lower numbers of intraepithelial CD33+ immature cells were detected in qCR when compared with other response groups. Importantly, the lesions of complete responders displayed a positive correlation between the numbers of CD4+, CD8+ T cells and CD14+ inflammatory myeloid cells infiltrating the stroma and epithelium, indicative of a coordinated immune response. Slow complete responders displayed increased intraepithelial infiltration of recently activated CD4+PD1+ T cells (p<0.05), but displayed a lower CD14+ and CD68+ myeloid cell infiltration when compared with qCR. The presence of a pre-existing coordinated infiltration of vHSIL lesions with CD4+ T cells, CD8+ T cells and CD14+ inflammatory myeloid cells in patients displaying a CR after imiquimod treatment confirms our previous findings and suggests their use as biomarkers to predict responsiveness, but may also function as biomarkers to reduce or extend treatment duration of imiquimod.

Objective To assess the clinical value of DNA methylation measurement in exfoliated cervical cells for distinguishing high-grade squamous intraepithelial lesions (HSIL) from other cervical abnormalities. Methods A total of 276 patients were enrolled, and general clinical information was collected. Exfoliated cervical cells were obtained to assess human papillomavirus (HPV) infection, conduct ThinPrep cytology tests (TCT), and measure methylation levels of JAM3 (△CtJ) and PAX1 (△CtP). Logistic regression was performed to identify factors significantly associated with HSIL diagnosis. A conditional inference tree model and the area under the curve (AUC) were employed to evaluate the efficacy of JAM3 and PAX1 methylation in detecting HSIL. Results Independent risk factors for HSIL diagnosis included △CtJ, △CtP, atypical squamous cells of undetermined significance (ASCUS), and HPV16 infection. The conditional inference tree indicated that 96.4% of patients were non-HSIL when △CtJ > 11.66, and 99.1% were non-HSIL when △CtP > 10.97. The diagnostic performance of △CtJ/△CtP surpassed that of TCT/HPV alone. Among six methods, the combination of △CtP, TCT, and high-risk HPV (hr-HPV) testing achieved the highest sensitivity (91.2%), positive predictive value (50.0%), negative predictive value (98.6%), and AUC (0.932). Conclusion In women with hr-HPV infection, DNA methylation analysis of cervical cytology outperformed traditional TCT or HPV testing. The combination of △CtP with TCT and HPV may offer the most accurate screening approach for HSIL.

Cervical cancer (CC) was considered to be the most common gynaecological cancer, with an estimated 342,000 deaths worldwide each year, as the majority of patients were diagnosed at an advanced stage of the disease. The purpose of this study was to evaluate the predictive value of multi-locus methylation assay for the early detection of CC. The cervical exfoliated cell samples from 492 HPV-positive females with cervical lesions were collected and subjected to methylation detection of gene FAM19A4, EPB41L3 and PAX1 after bisulfite conversion. The levels of gene methylation in patients with different severity of cervical lesions were evaluated and compared. The receiver-operating characteristic (ROC) curve was established and efficacy indexes such as sensitivity, specificity and area under the curve (AUC) were calculated to assess the diagnostic value of DNA methylation detection at multiple gene loci for CC. The methylation levels of FAM19A4, EPB41L3 and PAX1 were significantly increased with the grade of cervical squamous intraepithelial lesions. The sensitivities of FAM19A4, EPB41L3 and PAX1 alone for high-grade squamous intraepithelial lesion (HSIL) and CC diagnosis were 84.6%, 86.3% and 88.0%, respectively; when three markers were combined by a logistic regression model, the sensitivity was 88.0%, with a high specificity of 97.7% and AUC of 0.957 (95% CI 0.937–0.977). Methylation status of FAM19A4, EPB41L3 and PAX1 were highly specific and effective for monitoring the progression of cervical lesions and the tri-gene methylation assay could be used as a triage tool for CC early screening.

To synthesize the results of cost-effectiveness studies of different triage tests in comparison to repeat cytology for women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL) results. Electronic databases (Medline/PubMed, Lilacs, Embase, The Cochrane Library, Scopus, Web of Science, Scielo, The NHS Economic Evaluation Database, Econlit, and CEA Registry) were searched for cost-effectiveness or cost-utility publications. Per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent reviewers selected eligible publications based on the selection criteria and performed data extraction. Methodological quality was assessed using the Quality of Health Economic Studies tool. Five cost-effectiveness analyses were included comparing HPV testing, immediate colposcopy, and liquid-based cytology with HPV testing reflex to repeat cytology. The main outcome adopted was cervical intraepithelial neoplasia level 2 or higher (CIN2+) cases detected. In pairwise comparisons, HPV testing was more frequently observed as the most cost-effective strategy. Incremental cost-effectiveness ratios were very sensitive to costs of test kit variation and accuracy estimates with some sensitivity analysis scenarios showing immediate colposcopy more cost-effective than HPV testing depending on the tests' unitary costs and effectiveness. This systematic review of economic evidence corroborates clinical evidence showing cytology is the least effective, although less costly, triage strategy. Cytology-based triage programs need to be updated to offer timely treatment to women diagnosed with ASC-US/LSIL and better resource allocation.

Pleomorphic high-grade squamous intraepithelial lesions (PHSILs) of the uterine cervix are characterized by strikingly pleomorphic and enlarged nuclei with brisk mitotic activity. The aim of this study was to analyze the clinical outcomes of patients with PHSIL. Clinical data were collected from the electronic medical records of 44 patients with PHSIL. The patients' mean age was 52.1 years. The initial cytological diagnosis was HSIL in 43.2% of patients. High-risk human papillomavirus was detected in 89.5% of patients. The human papillomavirus type was not predominated by one specific type. The patients were treated with conization alone or with conization with subsequent hysterectomy. Two cases of squamous cell carcinoma coexisting with PHSIL, and one case of adenoid basal carcinoma were detected among the surgical specimens. Follow-up cytology revealed negative results for intraepithelial lesions in all patients, except for one patient who experienced recurrent PHSIL 41 months after hysterectomy and underwent laser ablation. The incidence rates of concurrent squamous cell carcinoma (4.5%) and recurrence (2.3%) in our PHSIL cohort were lower than those previously reported in patients with conventional HSIL. Our findings suggest that pleomorphic nuclear change alone in PHSIL was not associated with worse clinical outcomes than conventional HSIL and support the notion that PHSIL does not require more aggressive clinical management than conventional HSIL. However, close follow-up with cytological examination may be necessary to determine the potential risk of recurrence.

Objective To evaluate the feasibility of intraoperative human papillomavirus (IOP-HPV) testing for the prediction of postoperative treatment failure in patients with high-grade squamous intraepithelial lesion (HSIL) undergoing loop electrosurgical excisional procedure (LEEP). Methods A total of 114 women diagnosed with HSIL by biopsy and/or endocervical curettage who underwent LEEP were included in a prospective cohort study. IOP-HPV testing was performed immediately after the procedure. Patients were followed up for 24 months. Logistic regression was used to analyse the factors influencing the residual or recurrent lesions. Further stratified analyses were performed to investigate the differences in prognosis of IOP-HPV positivity in patients of different age and menopausal status. Results 1. Of the 114 patients, 6 (5.26%) were pathologically upgraded to cervical cancer, and 21 (18.42%) were lost to follow-up. Recurrence or residual HSIL lesions occurred in 9.20% (8/87) of cases. Of the 8 women who developed post-treatment HSIL, 7 (26.92%) were positive for IOP-HPV, and only 1 (1.64%) was negative for IOP-HPV (< 0.01). 2. Transformation zones of type 2 ( P  = 0.0306) or type 3 ( P  = 0.0446), diagnosed as LSIL/negative by cervical biopsy ( P  = 0.0396), margin involvement ( P  = 0.0233), positive endocervical curettage after conisation ( P  = 0.0028), intraoperative HPV-positive ( P  < 0.01), cytological abnormalities ( P  = 0.0038), DNA ploidy positivity ( P  = 0.0172), postoperative HPV ( P  < 0.01) and DNA ploidy ( P  = 0.0078) positivity at 6 months were associated with higher risk of residual or recurrent lesions.  3. The results of the multivariate regression analysis showed that IOP-HPV positivity was the independent risk factor for residual or recurrent lesions (OR=10.69 , 95% CI:3.41, 33.51, P<0.01). IOP-HPV positivity was strongly associated with the occurrence of residual/recurrent LSIL (OR=6.42 , 95% CI:1.74, 23.70, P =0.0053) and HSIL (OR=32.08 , 95% CI:3.60, 285.64, P =0.0019). 4. Stratified analyses showed that IOP-HPV positive in patients younger than 50 years or premenopausal patients was associated with a significantly higher risk of recurrence or residual lesions ( p <0.05). Conclusions IOP-HPV positivity is an independent risk factor for residual or recurrent HSIL lesions. In addition, IOP-HPV positivity was more associated with residual or recurrent lesions in those younger than 50 years or premenopausal. IOP-HPV testing may be of critical clinical value in providing the early and accurate prediction of residual or recurrent lesions.

The objective of this study was to delineate the profile of peripheral blood lymphocytic indices in patients afflicted with high-grade squamous intraepithelial lesions (HSIL) and cervical neoplasms, and to elucidate the correlation of these hematologic markers with the clinicopathological spectra in individuals diagnosed with cervical carcinoma. We adopted a retrospective case-control modality for this investigation. An aggregate of 39 HSIL patients and 42 cervical carcinoma patients, who were treated in our facility from July 2020 to September 2023, were meticulously selected. Each case of cervical malignancy was confirmed through rigorous histopathological scrutiny. Concomitantly, 31 healthy female individuals, who underwent prophylactic health evaluations during the corresponding timeframe, were enlisted as the baseline control group. We systematically gathered and analyzed clinical demographics, as well as the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), from peripheral blood samples. Pearson's correlation coefficient was deployed to dissect the interrelation between peripheral NLR and PLR concentrations and the clinicopathological features in the cervical cancer group. Inter-group comparative analysis unveiled statistically substantial variances in the PLR and NLR values among the tripartite clusters (  = 36.941, 14.998,  < 0.001, respectively). Although discrepancy in NLR (  = 0.061) and PLR (  = 0.759) measures between the groups of cervical carcinoma and HSIL was not statistically appreciable, these indices were markedly elevated in the cervical carcinoma faction as juxtaposed with the normative control group (  = 5.094, 5.927;  < 0.001 for both parameters). A discernible gradation in peripheral blood PLR and NLR concentrations was noted when stratified by clinical stage and the profundity of myometrial invasion in cervical cancer subjects (  < 0.001). The correlation matrix demonstrated a positive liaison between peripheral blood PLR and the clinical gradation, as well as the invasiveness of the neoplastic cells into the muscularis propria (  < 0.05); a similar trend was observed with the NLR values (  < 0.05). Augmented NLR and PLR levels in peripheral blood specimens are indicative of HSIL and cervical malignancy. These hematological parameters exhibit a pronounced interconnection with clinical staging and muscular wall penetration depth, serving as potential discriminative biomarkers for the diagnosis and prognosis of cervical cancer.
