Abstract
OBJECTIVES to evaluate whether the colposcopic lesion size , age, kind of surgery, the status of the surgical margins and the expression of the p16 and Ki-67 immunomarkers are risk factors for persistence or recurrence of the lesion. METHODS a cross-sectional, observational, retrospective study of patients submitted to cold knife conization (CKC) or the loop electrosurgical excision procedure for cervical intraepithelial neoplasia 2 or 3. The colposcopic lesion size, age, surgical method, involvement of the surgical margins, and p16/Ki-67 immunomarker expression were analyzed in relation to lesion persistence and recurrence. RESULTS seventy-one women were treated with cold knife conization and 200 were treated with loop electrosurgical excision. Of these, 95 had cervical intraepithelial neoplasia 2, 173 had cervical intraepithelial neoplasia 3, 183 had free surgical margins, 76 had compromised margins, and 12 showed damage by processing artifact or fragments. Among the 76 cases with positive margins, 55, 11, and 10 showed endocervical margin involvement, ectocervical margin involvement, and both endocervial and ectocervical margin involvement, respectively. Of the 264 followed-up patients, 38 had persistent or recurrent disease. A multiple logistic regression indicated that positive endocervical margins are the only independent risk factor for the persistence/recurrence of cervical intraepithelial neoplasia. No significant association was identified between the colposcopic lesion size, age, surgery type, or p16/Ki-67 immunomarker expression and lesion persistence or recurrence.

P16 expression and recurrent cervical intraepithelial neoplasia after cryotherapy among women living with HIV. Front Med (Lausanne) 2023; 10:1277480.

Abstract
Background The expression of p16 protein, a surrogate marker for high-risk human papillomavirus (hrHPV), is associated with cervical dysplasia. We evaluated correlates of p16 expression at treatment for high-grade cervical lesions and its utility in predicting the recurrence of cervical intraepithelial lesions grade 2 or higher (CIN2+) following cryotherapy among women with HIV. Methods This is a subgroup analysis of women with HIV in Kenya with baseline cervical biopsy-confirmed CIN2+ who were randomized to receive cryotherapy and followed every six-months for two-years for biopsy-confirmed recurrence of CIN2+. P16 immunohistochemistry was performed on the baseline cervical biopsy with a positive result defined as strong abnormal nuclear expression in a continuous block segment of cells (at least 10-20 cells). Results Among the 200 women with CIN2+ randomized to cryotherapy, 160 (80%) had a baseline cervical biopsy specimen available, of whom 94 (59%) were p16-positive. p16 expression at baseline was associated with presence of any one of 14 hrHPV genotypes [Odds Ratio (OR) = 3.2; 95% Confidence Interval (CI), 1.03-9.78], multiple lifetime sexual partners (OR = 1.6; 95% CI, 1.03-2.54) and detectable plasma HIV viral load (>1,000 copies/mL; OR = 1.43; 95% CI, 1.01-2.03). Longer antiretroviral therapy duration (≥2 years) at baseline had lower odds of p16 expression (OR = 0.46; 95% CI, 0.24-0.87) than <2 years of antiretroviral therapy. Fifty-one women had CIN2+ recurrence over 2-years, of whom 33 (65%) were p16-positive at baseline. p16 was not associated with CIN2+ recurrence (Hazard Ratio = 1.35; 95% CI, 0.76-2.40). Conclusion In this population of women with HIV and CIN2+, 41% of lesions were p16 negative and baseline p16 expression did not predict recurrence of cervical neoplasia during two-year follow up.

Recurrence in Cervical High-Grade Squamous Intraepithelial Lesion: The Role of the Excised Endocervical Canal Length-Analysis of 2,427 Patients. J Low Genit Tract Dis 2022; 27:1-6.

Abstract
OBJECTIVE This study aimed to evaluate the influence of the excised canal length on relapse rates of cervical high-grade squamous intraepithelial lesion (HSIL) treated by loop electrosurgical excision procedure and to find a cut-off point, above which lower recurrence rates could be observed, with low probability of compromising future obstetric outcome, and the relationship with other individual factors related to HSIL recurrence. METHOD This was a retrospective cohort study of 2,427 women diagnosed with cervical intraepithelial neoplasia CIN2+ who underwent cervical conization using the high-frequency loop electrosurgical excision procedure surgery technique, to analyze the role of endocervical canal length associated with individual factors in the recurrent disease after CIN2+ treatment and determine a cut-off point for the excised canal length needed to decrease the risk of disease relapse. RESULTS In 2,427 cases, the relapse rate of HSIL treated was 12%. Compromised margins of conization, HIV+, and endocervical canal length were related directly to relapses (p < .001). The cut-off point, by receiver operating characteristic curve, to calculate the endocervical canal length related to relapses was 1.25 cm of canal excised. Canal length of less than 1.25 cm increased the recurrence rate 2.5 times. Compromised margins and HIV+ increased recurrence rates by more than 5 times. CONCLUSION Cervical HSIL recurrence was directly related to the endocervical canal length: excised canal length of 1.25 cm or more decreases recurrence rate; HIV and compromised margins increase the chance of recurrence by more than 5 times.

[PMID: 34111875 DOI: 10.1159/000515894] [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: 07/08/2020] [Accepted: 03/14/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Our main objective was to assess the association between the markers p16 and Ki-67 and recurrence of disease in patients previously treated for cervical high-grade squamous intraepithelial lesion (HSIL). DESIGN This is a case-control study at the National Cancer Institute conducted between 2005 and 2015. Of the patients with a pathologically confirmed diagnosis of HSIL, 107 cases were selected. They were divided into 2 groups: 28 cases with recurrence after treatment and a control group of 79 patients without recurrence. We identified clinical, pathological, and treatment variables. METHODS Two experienced pathologists performed immunohistochemical analysis of biomarkers; they agreed on their interpretation, and we calculated the odds ratios (ORs) associated with recurrence. For group comparisons, we used the Wilcoxon signed-rank, χ2, or Fisher's exact test, depending on the type of variable. We conducted logistic regression models to estimate ORs and determine the factors associated with recurrence. The recurrence-free period was defined as the time frame between conization and either recurrence of disease or the last date the patient was seen. We used Kaplan-Meier plots to visualize survival curves and log-rank tests to compare the curves. We established a p value <0.05 as statistically significant. RESULTS After pathologists performed immunohistochemical analysis, they achieved an agreement level of 83.7% for p16 and 60% for Ki-67. We did not find an association between recurrence and either p16 expression (p = 0.69) or the percentage of Ki-67 expression (p = 0.71). The recurrence-free period analysis did not reveal a difference in p16 expression (p = 0.57) nor in the percentage of Ki-67 expression in the 3-tiered scale (p = 0.56). LIMITATIONS Our main limitation was a reduced sample size. CONCLUSION We found no association between p16 and Ki-67 positivity and the risk of recurrence in previously treated HSIL.

Abstract
Objective to study the association between the histological grading of cervical intraepithelial neoplasia (CIN I, CIN II and CIN III) and the immunohistochemical expression for p16ink4a, hTert and Ki67, as well as to evaluate the relationship of these markers with the risk of recurrence after surgical treatment. Methods we studied a historical cohort of 94 women with intraepithelial lesions CIN I (low grade), CIN II and CIN III (high grades) submitted to conization or electrosurgical excision of the transformation zone. We evaluated all surgical specimens for immunohistochemical expression of p16ink4a, hTert and Ki67. Results the mean age was 38.2 years; p16ink4a was absent in most CIN I cases. In patients with CIN II or I/II (association of low and high-grade lesions), we observed p16ink4a ≤10%. In patients with CIN III, we found a higher expression frequency of p16ink4a >50%. In CIN I, the majority had Ki67≤10% and low frequency of Ki67>50%. In the CIN III category, there were fewer patients with Ki67≤10%, and Ki67 was absent in most patients of CIN II and III groups. There was no association between hTert expression and histologic grade. There were no statistically significant differences between the expression of the markers in patients with and without recurrence. Conclusion there was a statistically significant association of p16ink4a and Ki67 with histological grade. The markers' expression, as for disease recurrence, was not statistically significant in the period evaluated.
