Recurrence in Cervical High-Grade Squamous Intraepithelial Lesion: The Role of the Excised Endocervical Canal Length-Analysis of 2,427 Patients.

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.

Therapeutic Assessment of Vulvar Squamous Intraepithelial Lesions with CO2 Laser Vaporization in Immunosuppressed Patients.

OBJECTIVE: A vulvar squamous intraepithelial lesion is deemed to be a preceding lesion to vulvar cancer, especially in women aged under 40 years, holders of an acquired or idiopathic immunosuppression. Several treatments have been used to treat these lesions. One of the aesthetically acceptable therapeutic methods is the CO2 laser vaporization. METHODS: In a transversal study, 46 records of immunosuppressed women bearing a vulvar low grade and/or high grade squamous intraepithelial lesion were selected out of the retrospective analysis, computing age, date of record, date of vulvar lesion treatment with CO2 laser, the time elapsed between the first and the last visit (in months), the number of visits, the presence or absence of condylomatous lesions in other female lower genital tract sites and whether or not recurrences and persistence of intraepithelial lesions have been noticed during the follow-up. RESULTS: Patients bearing vulvar high-grade squamous intraepithelial lesion and immunosuppressed (serum positive for human immunodeficiency virus [HIV] or with solid organs transplantation) have shown a higher level of persistence of lesions and a higher chance of having other areas of the female lower genital tract involved. CONCLUSION: While the CO2 laser vaporization is the most conservative method for the treatment of vulvar high-grade intraepithelial lesions, it is far from being the ideal method, due to the intrinsic infection features considered. The possibility of persistence, recurrences and spontaneous limited regression indicates that a closer surveillance in the long-term treated cases should be considered, in special for immunosuppressed patients.

OBJETIVO: A lesão intraepitelial escamosa da vulva é considerada uma lesão precursora do câncer vulvar, em especial em mulheres com idade inferior a 40 anos, portadoras de imunossupressão adquirida ou idiopática. Vários tratamentos têm sido utilizados para tratar esse tipo de lesão. Um dos métodos terapêuticos esteticamente aceitáveis é a vaporização a laser CO2. MéTODOS: Em um estudo transversal, foram selecionados da análise retrospectiva de prontuários arquivados no setor de patologia do trato genital inferior 46 prontuários de mulheres com imunossupressão e portadoras de lesão intraepitelial escamosa de baixo grau e/ou alto grau computando-se: idade, data de registro, data do tratamento da lesão vulvar com laser CO2, tempo entre a primeira e a última consulta (em meses), número de consultas, presença ou ausência de lesões condilomatosas em outros locais do aparelho reprodutor feminino e a ocorrência ou não de recidivas e persistência de lesões intraepiteliais durante o período de acompanhamento. RESULTADOS: Pacientes com lesão intraepitelial de alto grau vulvar e imunocomprometidas (soropositivas para HIV ou com transplante de órgãos sólidos) mostraram maior índice de persistência das lesões e maior chance de ter outras áreas do órgão genital feminino comprometidas. CONCLUSãO: Embora a vaporização a laser CO2 seja o método mais conservador para o tratamento das lesões intraepiteliais vulvares de alto grau, está longe de ser o método ideal pelas características intrínsecas da afecção em foco. A possibilidade de persistência, recidivas e regressão espontânea limitada recomenda maior vigilância para os casos tratados a longo prazo, em especial para as pacientes com imunossupressão.

Predictors of Positive Margins at Time of Loop Electrosurgical Excision Procedure.

OBJECTIVE: The aim of the study was to identify factors associated with the presence of high-grade squamous intraepithelial lesion (HSIL) at surgical margins of loop electrosurgical excision procedure (LEEP) pathology specimens. MATERIALS AND METHODS: All women evaluated for lower genital tract disease at a single academic institution were prospectively entered into a database. The database was queried for all women who had a LEEP performed for indications within contemporary American Society of Colposcopy and Cervical Pathology guidelines between April 1, 2013, and April 30, 2015. Factors extracted from the database included demographics, contraception, weight, tobacco use, provider volume, resident participation, history of cervical procedure, and pathology features including preceding Pap test category. A positive margin was defined as HSIL on either the endocervical or ectocervical margin of the LEEP specimen or in endocervical curettage specimen after LEEP. We performed univariable statistics to identify factors associated with positive margins and then logistic regression modeling on significant factors for the outcome of positive margins. RESULTS: Two hundred sixty-nine women were identified. Seventy five (27.8%) of these women had positive margins. Only tobacco use, gravity, parity, and preceding Pap category were significant on univariable analysis. After multivariable analysis, smokers remained more likely to have positive margins (odds ratio = 2.01; CI = 1.12-3.6; p < .01) as did those with preceding HSIL Pap tests (odds ratio = 1.96; CI = 1.13-3.41; p < .01). CONCLUSIONS: In our population, of all the factors assessed, only tobacco use and preceding high-grade Pap tests were associated with positive margins at time of LEEP. This information may be helpful in preprocedural planning to optimize treatment.

Multivariate analysis of risk factors for the persistence of high-grade squamous intraepithelial lesions following loop electrosurgical excision procedure.

OBJECTIVE: To evaluate risk factors related to the persistence of high-grade squamous intraepithelial lesions (HSILs) following loop electrosurgical excision procedure (LEEP). METHODS: The present prospective, observational study evaluated a convenience sample of participants with HSILs who were treated using LEEP between January 7, 2003 and December 30, 2011. Participants were evaluated 6months and 1year after treatment. Potential risk factors included in multivariate analyses were HIV co-infection, involved margins, multicentric lesions, smoking, and use of hormonal contraception. RESULTS: The present study enrolled 307 participants. At 1year, 250 (81.4%) participants were free from lesions, 30 (9.8%) had low-grade squamous intraepithelial lesions, 26 (8.5%) had persistent HSILs, and 1 (0.3%) had developed invasive carcinoma. The risk of lesions persisting at 1year after LEEP was increased by HIV infection (P=0.003), involved margins (P=0.05), and smoking (P=0.02). The presence of multicentric lesions (P=0.73) and the use of hormonal contraception (P=0.99) did not increase the risk of lesion persistence. The risk of HSIL persistence was increased by the presence of involved margins (relative risk 3.25; 95% confidence interval 1.55-6.80; P=0.001). CONCLUSIONS: The presence of involved margins was the only variable that increased the risk of HSIL persistence after LEEP, increasing the risk of patients requiring further treatment.

30 years of preventive studies of uterine cervical cancer 1982-2012.

The studies for the prevention of uterine cervical cancer in Panama City began in a private institute, impelled by the high incidence of cancer. The preventive programs were initiated with the support of the Obstetrics and Gynecology Institute of the University of Padua in Italy. In these studies, we applied the methodological diagnostics of this Institute with certain modifications adapted to our needs. The diagnosis, treatment, and follow-up were carried out under the protocol of the University of Padua. We achieved a diagnosis of oncogenic risk (OR) in 6,411 patients which corresponded to 5,498 cases of human papillomavirus (HPV), 1,150 cases of dysplasia, 210 cases of cancer, and 794 cases of OR. From 2011, polymerase chain reaction (PCR) was also applied with the aim to improve the accuracy of the diagnosis. With this method the prevalence of pathologies were HPV infections both in healthy patients or in patients cured from HPV. Patients were treated by means of local destructive treatments (LDT), basically with cryotherapy and cauterization. We can consider these results as successful prevention and suggest to extend a preventive program to all the population.
