Diagnosis and Management of Cervical Squamous Intraepithelial Lesions in Pregnancy and Postpartum.

Perinatal care provides important health care opportunities for many individuals at risk for cervical cancer. Pregnancy does not alter cervical cancer screening regimens. ASCCP risk-based management has a colposcopy threshold of a 4% immediate risk of cervical intraepithelial neoplasia (CIN) 3 or cancer, but the actual risk can be considerably higher based on current and past screening results. Improving cervical cancer outcomes with diagnosis during pregnancy rather than postpartum and facilitating further evaluation and treatment postpartum for lesser lesions are the perinatal management goals. Although colposcopy indications are unchanged in pregnancy, some individuals with lower risk of CIN 2-3 and reliable access to postpartum evaluation may defer colposcopy until after delivery. Cervical intraepithelial neoplasia diagnosed in pregnancy tends to be stable, with frequent regression postpartum, though this is not universal. Colposcopic inspection during pregnancy can be challenging. Although biopsies in pregnancy are subjectively associated with increased bleeding, they do not increase complications. Endocervical curettage and expedited treatment are unacceptable. Treatment of CIN 2-3 in pregnancy is not recommended. Excisional biopsies in pregnancy are reserved for suspicion of malignancy that cannot be confirmed by colposcopic biopsy and when excisional biopsy results would alter oncologic or pregnancy care. Surveillance of high-grade lesions in pregnancy uses human papillomavirus-based testing, cytology, and colposcopy, with biopsy of worsening lesions every 12-24 weeks from diagnosis until postpartum evaluation. Mode of delivery does not definitively affect persistence of CIN postpartum. Postpartum care may involve a full colposcopic evaluation or expedited excisional procedure if indicated.

Therapeutic DNA Vaccines against HPV-Related Malignancies: Promising Leads from Clinical Trials.

In 2014 and 2021, two nucleic-acid vaccine candidates named MAV E2 and VGX-3100 completed phase III clinical trials in Mexico and U.S., respectively, for patients with human papillomavirus (HPV)-related, high-grade squamous intraepithelial lesions (HSIL). These well-tolerated but still unlicensed vaccines encode distinct HPV antigens (E2 versus E6+E7) to elicit cell-mediated immune responses; their clinical efficacy, as measured by HSIL regression or cure, was modest when compared with placebo or surgery (conization), but both proved highly effective in clearing HPV infection, which should help further optimize strategies for enhancing vaccine immunogenicity, toward an ultimate goal of preventing malignancies in millions of patients who are living with persistent, oncogenic HPV infection but are not expected to benefit from current, prophylactic vaccines. The major roadblocks to a highly efficacious and practical product remain challenging and can be classified into five categories: (i) getting the vaccines into the right cells for efficient expression and presentation of HPV antigens (fusion proteins or epitopes); (ii) having adequate coverage of oncogenic HPV types, beyond the current focus on HPV-16 and -18; (iii) directing immune protection to various epithelial niches, especially anogenital mucosa and upper aerodigestive tract where HPV-transformed cells wreak havoc; (iv) establishing the time window and vaccination regimen, including dosage, interval and even combination therapy, for achieving maximum efficacy; and (v) validating therapeutic efficacy in patients with poor prognosis because of advanced, recurrent or non-resectable malignancies. Overall, the room for improvements is still large enough that continuing efforts for research and development will very likely extend into the next decade.

Safety and efficacy of mucosal immunotherapy using human papillomavirus (HPV) type 16 E7-expressing Lactobacillus-based vaccine for the treatment of high-grade squamous intraepithelial lesion (HSIL): the study protocol of a randomized placebo-controlled clinical trial (MILACLE study).

We developed an HPV16 E7-expressing Lactobacillus-based therapeutic vaccine, IGMKK16E7, to elicit mucosal E7-specific TH1 cellular immune responses. This study aims to examine the safety and clinical efficacy of IGMKK16E7 on HPV16-positive high-grade squamous intraepithelial lesion (HSIL). This is a multicenter, placebo-controlled, double-blind randomized phase I/II trial to test the safety and efficacy of IGMKK16E7 against HPV16-positive HSIL. The groups will include placebo, low-dose (0.5 g/day), middle-dose (1 g/day), and high-dose (1.5 g/day) IGMKK16E7. The target sample size will be 41 patients per group, and our data on our former agent, GLBL101c, were used to calculate sample size for 70% power and an α level = 0.05. The primary endpoint is IGMKK16E7 safety and pathological regression at week 16, and the secondary endpoints are cytological regression and HPV16 E7 immunological response. This study protocol has been approved by the Japanese Pharmaceuticals and Medical Devices Agency. Patient enrollment will begin in May 2019.

[Discussion on the diagnosis and treatment of high-grade squamous intraepithelial lesions in post-menopausal women].

Objective: To analyze the performance of colposcopy and investigate the diagnosis and treatment characteristics of high-grade squamous intraepithelial lesion (HSIL) diagnosed by cervical tissue sampling in post-menopausal women. Methods: A retrospective study was performed on 1 449 patients with HSIL diagnosed by cervical tissue sampling under colposcopy and treated by loop electrosurgical excision procedure (LEEP) or extrafascial hysterectomy as the primary therapy at the First Affiliated Hospital of Nanjing Medical University, from November 2015 to October 2017. In order to investigate the diagnosis and treatment of HSIL in post-menopausal women, a case-control study was conducted to compare the difference in performance of colposcopy and treatment modality between 213 post-menopausal patients (14.7%, 213/1 449) and 1 236 pre-menopausal patients (85.3%, 1 236/1 449). Results: (1)The proportion of cases pathologically upgraded to cervical cancer was significantly greater in post-menopausal patients (9.4%, 20/213) compared with pre-menopausal patients (3.8%, 47/1 236; P<0.05). (2) The proportion of ≥HSIL diagnosed by colposcopy showed no significant difference between post-menopausal patients (76.1%, 162/213) and pre-menopausal patients (78.2%, 967/1 236; P=0.479). The proportion of type Ⅲ transformation zone (TZ) was significantly greater in post-menopausal patients (91.1%, 194/213) compared with pre-menopausal patients (59.1%, 731/1 236; P<0.05). The rate of missed diagnosis of cervical cancer was significantly higher in type Ⅲ TZ (6.4%, 59/925) compared with type Ⅰ and(or) Ⅱ TZ (1.5%, 8/524; P<0.05). The proportion of HSIL detected by endocervical curettage alone was greater in post-menopausal patients (9.9%, 21/213) compared with pre-menopausal patients (2.6%, 32/1 236; P<0.05). (3)Initial treatment with LEEP: the positive rate of endocervical margin was significantly greater in post-menopausal patients (20.5%, 36/176) compared with pre-menopausal patients (10.5%, 130/1 236;P<0.05); in patients who were diagnosed as HSIL after LEEP, the positive rate of endocervical margin and the residual rate were both greater in post-menopausal patients compared with pre-menopausal patients [15.4% (25/162) versus 8.8% (105/1 189), P=0.008; 52.0% (13/25) versus 26.7% (28/105), P=0.014]. (4)Thirty-seven post-menopausal patients were treated by extrafascial hysterectomy as the primary therapy, 5 cases (13.5%, 5/37) were diagnosed as cervical cancer (stage Ⅰa1) after the surgery. Conclusions: (1) The lesions of HSIL in post-menopausal patients still have definite features under colposcopy as same as pre-menopausal patients. Endocervical curettage could help detect more HSIL in post-menopausal patients. Compared with pre-menopausal patients, post-menopausal HSIL patients have an increased risk of cervical cancer and are more likely missed by cervical tissue sampling. (2) LEEP has the dual effects of diagnosis and treatment, and is still the recommended treatment for post-menopausal HSIL patients. However, the increase in positive rate of endocervical margin and residual rate requires further active intervention. (3) Considering those post-menopausal HSIL patients who cannot accept conization as the initial treatment, the selection of hysterectomy type requires more thorough study.

Impact of Patient-Directed Cytology Results Correspondence Program on Follow-Up of High-Grade Pap Tests.

OBJECTIVE: Proper follow-up of high-grade (HG) Pap tests is critical to the prevention of cervical cancer. This study evaluated the impact of a patient-directed cytology results correspondence program on follow-up of HG Pap tests among at-risk women aged 21 to 69 in Ontario. METHODS: A cohort study with a historical control was used to investigate the impact of a result letter on adherence to follow-up after an HG Pap test. Analyses were conducted on an intention-to-treat basis. The intervention group was defined as women with an HG Pap test in 2014-2016, and the control group included women with an HG Pap test in 2010-2012. Follow-up was defined as a colposcopy or related treatments within 6 months of an HG Pap test. Factors that could influence adherence to follow-up were included as covariates in a multivariable logistic regression model (Canadian Task Force Classification II-2). RESULTS: The study population comprised 7088 women in the intervention group and 6887 women in the non-intervention group. The follow-up rate in the intervention group was 86.2% compared with 81.0% in the non-intervention group. Controlling for covariates, women in the intervention group were more likely to have a follow-up (adjusted odds ratio 1.5; 95% confidence interval 1.3-1.6). Other significant factors included being registered to a family physician and the physician's gender. CONCLUSIONS: A patient-directed correspondence program that provides Pap test results directly to the woman may reduce loss to follow-up for an HG abnormality, with an increased likelihood that these women will seek and complete a colposcopy and related treatment.

Reliability and between-group stability of a health-related quality of life symptom index for persons with anal high-grade squamous intraepithelial lesions: an AIDS Malignancy Consortium Study (AMC-A03).

PURPOSE: The Anal Cancer HSIL Outcomes Research (ANCHOR) trial aims to determine whether treating precancerous anal high-grade squamous intraepithelial lesions (HSIL), versus active surveillance, is effective in reducing anal cancer incidence in HIV-infected individuals. We evaluated the reliability (i.e., internal consistency, test-retest) and between-group stability of a 25-item ANCHOR Health-Related Symptom Index (A-HRSI). METHODS: ANCHOR participants at least 1-month post-randomization to treatment or active surveillance completed the A-HRSI via telephone. Participants were contacted 7-10 days later to complete the A-HRSI and a participant global impression of change (PGIC) item. RESULTS: Participants (n = 100) were enrolled (mean age = 51.4, 79% cisgender-male, 73% African American, 9% Hispanic) from five ANCHOR sites. Cronbach's α was good for the physical symptoms (0.82) domain and fair for the physical impacts (0.79) and psychological symptoms (0.73) domains. Intraclass correlation coefficients were good for each of respective domains (i.e., 0.80, 0.85, and 0.82). There were no significant differences in PGIC between the treatment (n = 56) and active surveillance (n = 44) groups (F(1,98) = 2.03, p = 0.16). CONCLUSIONS: The A-HRSI is able to reliably assess participant-reported symptoms and impacts of anal HSIL across a 7-10 days of timeframe. Future work will involve the establishment of construct and discriminant validity prior to inclusion in the full ANCHOR trial.

Human papillomavirus-related malignancies in HIV infection: anal and oropharyngeal cancers.

Human papillomavirus (HPV)-related cancers, including anal cancer and oropharyngeal cancer, occur more frequently in individuals living with HIV infection than in the general population. Strategies for prevention among individuals with HIV infection include HPV vaccination, anal cancer screening programs, and early initiation of antiretroviral therapy (ART). HPV vaccination is not yet optimally used; a stronger and more persistent effort is needed to increase vaccination rates. Although anal cancer screening is not recommended by all authorities, there is a least some evidence that screening and treatment of anal high-grade squamous intraepithelial lesions may prevent progression to cancer. However, more definitive evidence is needed. Early initiation of ART reduces the risk of infection-related cancers, with some evidence of benefit in preventing HPV-associated cancer in individuals with HIV infection. This article summarizes a presentation by Timothy J. Wilkin, MD, MPH, at the IAS-USA continuing education program held in Los Angeles, California in April 2018.

Brief Report: Effectiveness of Trichloroacetic Acid vs. Electrocautery Ablation for the Treatment of Anal High-Grade Squamous Intraepithelial Lesion in HIV-Infected Patients.

BACKGROUND: Trichloroacetic acid (TCA) and electrocautery ablation (ECA) are 2 of the main treatment options for anal high-grade squamous intraepithelial lesion (HSIL). Our aim was to compare the efficacy and tolerance of TCA vs. ECA for HSIL. METHODS: Retrospective uncontrolled study of HIV-infected men who have sex with men who had an anal HSIL treated with TCA or ECA. On-treatment effectiveness was evaluated at 6-8 weeks after treatment. A complete response was defined as resolution of HSIL, a partial response as regression to low-grade lesion, and recurrence as biopsy-proven HSIL during follow-up. A propensity-score analysis was used to adjust efficacy to potential confounding. RESULTS: From May 2009 to March 2018, 182 and 56 cases of anal HSIL were treated with ECA and TCA, respectively. Comparing ECA with TCA, a complete response was observed in 33.5% (95% confidence interval: 25.8 to 41.6) vs. 60.7% (50.0 to 74.8) and a partial response in 28.0% (20.3 to 36.0) vs. 23.2% (12.5 to 37.3), respectively (P < 0.001). These differences were maintained in the propensity-score analyses. Side effects were common in both treatment, but tolerance was reported as good in 80.6% (74.2 to 89.2) and 82.6% (73.9 to 93.9) of cases treated with ECA and TCA, respectively, and no serious events were described. Recurrence cumulative incidence for the first 12 months was 14.6% (9.1 to 23.1) for ECA episodes and 27.6% (11.5 to 57.7) for TCA (P = 0.183). CONCLUSIONS: Our study showed a higher efficacy of TCA than ECA with similar rates of side effects. In our opinion, considering the benefits of TCA, it should be considered as a first-line therapy for most anal HSIL management.

Outcomes of Conservative Management of High Grade Squamous Intraepithelial Lesions in Young Women.

OBJECTIVE: The aim of the study was to determine regression rates of cervical intraepithelial neoplasia (CIN) 2 and 3 in women younger than 24 years, followed conservatively for up to 24 months. MATERIALS AND METHODS: This is a retrospective chart review of colposcopy patients in clinic database based on the following: (1) younger than 24 years at first visit; (2) first visit January 1, 2010, to May 31, 2013, and at least 1 follow-up visit after diagnosis; (3) histologic diagnosis of CIN2+; and (4) optimal conservative management (observation for up to 24 months or to 24 years, whichever occurred first). Patient information and clinical/pathologic data were extracted from charts to examine patient characteristics and treatment outcomes, CIN2+ regression rates, median times to regression for CIN2 versus CIN3 (Kaplan-Meier survival analysis), and predictors of regression (multivariate logistic regression analysis). RESULTS: A total of 154 women met criteria. The most severe histological diagnoses were CIN2 in 99 (64.3%), CIN3 in 51 (33.1%), and adenocarcinoma in situ in 4 (2.6%). Adenocarcinoma in situ was immediately treated. In follow-up, CIN2 regressed to CIN1 or negative in 74 women (74.7%)-median time to regression, 10.8 months. Cervical intraepithelial neoplasia 3 regressed in 11 women (21.6%)-median time to regression not reached (last follow-up censored at 52.7 months). Cervical intraepithelial neoplasia 2 on biopsy, low grade referral Pap, and younger age predicted regression. Overall, 49 women (31.8%) were treated. CONCLUSIONS: Conservative management should continue to be recommended to young women with CIN2. Rigorous retention mechanisms are required to ensure that these women return for follow-up.

Natural History of Squamous Intraepithelial Lesions in Pregnancy and Mode of Delivery.

BACKGROUND: Numerous studies have addressed the impact of mode of delivery on the natural history of squamous intraepithelial lesions (SIL) in pregnant women. However, the literature is still contradictory. PATIENTS AND METHODS: In the course of a retrospective analysis, data of 63 pregnant women with abnormal cervical smears who were referred to our Outpatient Department for pre-invasive lesions of the cervix were analyzed. The study was conducted at the General Hospital in Vienna, Austria, between 2010 and 2015. Data collection included demographics, delivery route and diagnostic results of cervical lesions by cytology, colposcopy, human papilloma virus (HPV) testing, histological report of punch biopsy and, if applicable, cone biopsy. RESULTS: Among 63 women who met the inclusion criteria, 40 (63%) delivered vaginally and 23 (37%) underwent caesarean section. Postpartum regression of cervical dysplasia was documented in 15 women delivering vaginally and in 10 who had a caesarean section (p=0.641). Among those women who delivered vaginally, three had progression and in 22 women the lesions persisted postpartum. In the group of women with caesarean section, one had progression and the lesions of 12 women persisted after delivery. No woman had progression to invasive disease. CONCLUSION: The mode of delivery does not significantly influence the natural history of cervical dysplastic lesions in pregnant women. The numbers of spontaneous regressions to normal cervical cytology during pregnancy were similar in both groups.

Argon plasma coagulation treatment of anal high-grade squamous intraepithelial lesions in men who have sex with men living with HIV: results of a 2-year prospective pilot study.

OBJECTIVES: Men who have sex with men (MSM) living with HIV are at high risk for anal high-grade squamous intraepithelial lesions (HSILs) and cancer. The best management of anal HSIL remains unclear. Our objective was to assess whether argon plasma coagulation (APC) could be safe, well tolerated and efficient to treat anal HSILs in MSM living with HIV. METHODS: A prospective phase II, open-label, pilot study was conducted to evaluate APC to treat anal HSILs in 20 HIV-positive MSM. Participants were followed for 2 years after their first treatment. RESULTS: Twenty men with persistent HSILs completed the 2-year study. Their baseline median CD4 count was 490 cells/µL and 85% had undetectable HIV viral loads. Overall, 65% (13/20) of participants were clear of HSILs at their 24-month visit. The initial response rates after the first, second and third APC treatments were 45%, 44% and 67%, respectively, but recurrences were common. The main side effect was pain during and within 1 week after the treatments. There were no long-term side effects, nor serious adverse events related to the procedure. Cost is a drawback. CONCLUSIONS: APC can be used to treat anal HSILs in HIV-seropositive MSM, and requires repeated treatment because of a high recurrence rate. As successful treatment of human papillomavirus (HPV) infection or eradication of the anal transitional zone remains impossible, HSIL treatment is challenging and requires long-term follow-up.

Clinical management and risk reduction in women with low-grade squamous intraepithelial lesion cytology: A population-based cohort study.

We analyzed the management and risk of subsequent cervical intraepithelial neoplasm 3 (CIN3) and invasive cervical cancer in women with low-grade squamous intraepithelial lesion (LSIL) cytology. A total of 53,293 women with a new diagnosis of cytologic LSIL were identified in Taiwan's national cervical screening registration database. Based on the retrieved clinical management data, the incidence of subsequent CIN3+ lesions was determined, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. The average follow-up was 5.02 years. A total of 988 women developed CIN3+ lesions during this period, with an overall incidence of 369.3 women per 100,000 person-years. Cryotherapy and conization/loop electrosurgical excision procedure (LEEP) decreased the subsequent risk of CIN3+ lesions in women younger than 50 years (HR 0.49, 95% confidence interval [CI] 0.37-0.64, p<0.0001 for cryotherapy; HR 0.39, 95% CI 0.27-0.55, p<0.0001 for LEEP). Cryotherapy and conization/LEEP were two significant protective factors for developing CIN3+ lesions, especially in women with biopsy-proven CIN1 (HR 0.55, 95% CI 0.37-0.82, p = 0.003 for cryotherapy; HR 0.43, 95% CI 0.24-0.77, p = 0.005 for LEEP). These results suggest that when women are first screened LSIL and lack prior abnormal cervical cytology, cryotherapy should be one of the treatment options. Younger women with a histological biopsy diagnosis of CIN1 were most likely to benefit from cryotherapy.

Diagnostic and Treatment Reproducibility of Cervical Intraepithelial Neoplasia / Squamous Intraepithelial Lesion and Factors Affecting the Diagnosis.

OBJECTIVE: Inter-observer differences in the diagnosis of HPV related cervical lesions are problematic and response of gynecologists to these diagnostic entities is non-standardized. This study evaluated the diagnostic reproducibility of "cervical intraepithelial neoplasia" (CIN) and "squamous intraepithelial lesion" (SIL) diagnoses. MATERIAL AND METHOD: 19 pathologists evaluated 66 cases once using H&E slides and once with immunohistochemical studies (p16, Ki-67 and Pro-ExC). Management response to diagnoses was evaluated amongst 12 gynecologists. Pathologists and gynecologists were also given a questionnaire about how additional information like smear results and age modify diagnosis and management. RESULTS: We show moderate interobserver diagnostic reproducibility amongst pathologists. The overall kappa value was 0.50 and 0.59 using the CIN and SIL classifications respectively. Impact of immunohistochemical evaluation on interpretation of cases differed and there was lack of statistically significant improvement of interobserver diagnostic reproducibility with the addition of immunohistochemistry. We saw that choice of treatment methods amongst gynecologists varied and overall concordance was only fair to moderate. The CIN2 diagnostic category was seen to have the lowest percentage agreement amongst both pathologists and gynecologists. We showed that pathologists had diagnostic "styles" and gynecologists had management "styles". CONCLUSION: In summary each pathologist had different diagnostic tendencies which were affected not only by histopathology and marker studies, but also by the patient management tendencies of the gynecologist that the pathologist worked with. The two-tiered modified Bethesda system improved diagnostic agreement. We concluded that immunohistochemistry should be used only to resolve problems in select cases and not for every case.

The effect of video information on anxiety levels in women attending colposcopy: a randomized controlled trial.

OBJECTIVE: The aim was to investigate whether additional information, in video form, reduces anxiety, depression and pain levels in women referred for colposcopy. MATERIAL AND METHODS: Between September 2012 and March 2015, 136 patients referred for colposcopy were randomized into two study arms. Group A received video information in addition to the regular information leaflet, and group B (control group) received only the regular information leaflet. The patients were requested to complete standardized online questionnaires. The first online questionnaire (T1) was pre-randomization, and was completed at home, 5 days prior to the appointment. The second online questionnaire (T2) was completed directly before the colposcopy appointment, and the last online questionnaire (T3) was completed directly following colposcopy at the out-patient clinic. The questionnaires included the Spielberger State-Trait Anxiety Inventory (STAI), the Hospital Anxiety and Depression Scale (HADS), and the Numeric Rating Scale (NRS) to assess pain. RESULTS: The STAI state anxiety score was high (44.6), but there was no significant difference in STAI, HADS and NRS between the two groups at the three measuring points. A post hoc analysis showed that women with a generally higher baseline anxiety trait had significantly lower HADS anxiety levels following video information. CONCLUSIONS: Additional information (video) before colposcopy did not significantly reduce anxiety, depression, and expected or experienced pain, as measured by the STAI, HADS and NRS in patients attending their first colposcopy appointment. However, most patients positively appreciated the video information, which may reduce the anxiety of extremely anxious patients.

Triaging Atypical Squamous Cells-Cannot Exclude High-Grade Squamous Intraepithelial Lesion With p16/Ki67 Dual Stain.

OBJECTIVES: The management of women with Pap cytology results categorized as "atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion" (ASC-H) can often be challenging. We assessed the performance of p16/Ki67 dual-stained cytology as a potential triage tool for the detection of biopsy-confirmed high-grade squamous intraepithelial lesions (HSILs) in women with ASC-H. MATERIALS AND METHODS: Women with ASC-H were followed for a period of 36 months by repeat cytology and colposcopy. p16/Ki67 dual staining was performed retrospectively on the initial Pap cytology slide with ASC-H interpretation. Results were compared with the final histological diagnosis and/or cytological follow-up for at least 1 year. All outcomes were defined as clinically significant at the threshold of HSIL (cervical intraepithelial neoplasia grade 2 or worse). RESULTS: One hundred sixty-nine cases fulfilled all conditions to be included in the study group. The rate of histologically confirmed HSIL was 57.4%, low-grade squamous intraepithelial lesion was diagnosed in 17.7% of the patients and normal histology or follow-up in 24.9% of the patients. Overall sensitivity and specificity of p16/Ki67 dual stain were 95% and 72%, respectively. Overall positive likelihood ratio of p16/Ki67 in detection of HSIL was 3.41, considerably increasing pretest probability from 57% to posttest probability of 82%. CONCLUSIONS: A substantial subset of patients with ASC-H interpretations is associated with an appreciable risk of clinically significant cervical disease. p16/Ki67 dual stain can provide additional valuable information that may lead to higher-quality management of women with ASC-H, especially when initial colposcopy or biopsy results do not show HSIL lesions.

Follow-up of women with cervical cytological abnormalities showing atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion: a nationwide cohort study.

BACKGROUND: Atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion in abnormal cervical cytology among young women in cervical cancer screening is an increasing health burden, and comparative effectiveness studies of different management options for such diagnoses are needed. OBJECTIVE: The objective of the study was to compare the incidence of invasive cervical cancer, following different management options pursued after an atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion index smear. STUDY DESIGN: In this nationwide cohort study, we included all women aged 22-50 years and resident in Sweden 1989-2011 and with at least 1 cervical smear registered during the study period (n = 2,466,671). Follow-up of a first atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion cytological diagnosis within 25 months was classified as repeat cytology, colposcopy/biopsy, or without further assessment. Incidence rate ratios and 95% confidence intervals of subsequent cervical cancer within 6.5 years following atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion were estimated using Poisson regression by age group and management strategy. RESULTS: Women managed with repeat cytology within 6 months after atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion cytology had a similar risk of cervical cancer compared with colposcopy/biopsy (incidence rate ratio, 1.1, 95% confidence interval, 0.5-2.5, and incidence rate ratio, 2.0, 95% confidence interval, 0.6-6.5, respectively) among women aged 22-27 years. For women aged 28 years and older, women managed with repeat cytology had a higher risk for cervical cancer than women managed with colposcopy/biopsy. CONCLUSION: Our findings suggest that women with a first cytological diagnosis of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion up to age 27 years may indeed be safely followed up with repeat cytology within 6 months. A large amount of colposcopies that are currently performed in this group, therefore, could safely be discontinued.

[Analysis of histological type and staging of cervical cancer as prognostic factors among women treated in the Department of Gynecology and Oncology, Jagiellonian University in the years 2001-2014].

Introduction: Cervical cancer (CC) is the fourth most common, in terms of incidence of new cases, cancer in women and the third leading cause of cancer deaths in women worldwide. Survival of patients with CC depends on many factors, including the type of cancer, grading, FIGO staging and treatment. Material and Methods: Analysis of survival of 524 patients diagnosed with invasive and non-invasive CC depending on histopathologic diagnosis, clinical staging, tumor grading and combination of therapy. Results: The 2-fold increase in the risk of death at diagnosis in order of HSIL> ca planoepitheliale> adenocarcinoma> sarcoma was noted. Grading 2 and 3 significantly reduces the average survival in patients diagnosed with CC. The higher staging, the shorter the average survival. Each pass by one FIGO stage was shown to increase the risk of death by 46%. The risk of death increases by 4% with every year of woman's life. The longest average survival, 72 months, characterized a group of women undergoing curettage, followed by radical hysterectomy/ trachelectomy and lymphadenectomy without adiuvant radio-/ chemotherapy. The shortest survival, 26.9 months, was observed in the group treated with curettage followed by chemoradiation. Conclusions: Histopathology, clinical staging, grading, age and combination of treatment proved to be significant factors affecting survival in women with CC.

Conservative management of biopsy confirmed high-grade squamous intraepithelial lesions.

OBJECTIVES: Follow-up of women with biopsy-confirmed CIN2+ who were either treated immediately with LLETZ or managed conservatively to determine the rates of patients back on routine screening programme after a median of three years in two groups. METHODS: In this retrospective study, 310 patients were involved who had undergone biopsy with result of CIN2+ between January 2011 and December 2014. Depending on the management, i.e. based on whether cytology and colposcopy follow-up or immediate treatment were performed, they were divided in two groups. Then the number of patients back on routine screening up to 15/2/2016 as well as the results of last cytology were compared within both groups. RESULTS: A total of 310 women at average age of 30 years met the inclusion criteria. Of them, 230 (74 %) had immediate treatment whereas 80 (26 %) were managed conservatively. There were no statistically significant demographic differences between the two groups. The mean time of follow up was 1.091 days (2.98 years). The patients managed conservatively required more follow-up visits at colposcopy clinic (p<0.001). The last documented cytology in the immediate treatment group was negative in 93 % and low-grade/borderline in 7 % of patients, while in the conservative management group, it was negative in 84 %, low-grade/borderline in 15 % and high-grade in 1 % of patients (p = 0.015). Overall, the proportions of patients who are back on routine screening recall are 96 % and 87.5 % for the immediate treatment and conservatively managed groups, respectively (p=0.022). CONCLUSION: The conservative management of high-grade CIN with cytology and colposcopic follow up is an OPTION in selected group of patients, but it cannot be routinely recommended (Tab. 2, Ref. 20).
