Potential of non-Western medicines in chemoradiotherapy for cervical cancer

This editorial explores the potential integration of non-Western medicine into radiotherapy for cervical cancer.While radiotherapy remains a radical treatment for cervical cancer,its associated toxicity and decline in quality of life can significantly impact patients’lives.Currently,most treatments are supportive,with no specific treatment options available in Western medicine.Non-Western medicine,often less toxic and easier to administer,has shown promising results when used alongside radiotherapy for cervical cancer.Despite these potential benefits,challenges such as limited evidence and restricted application areas persist.While non-Western medicines may offer potential improvements in chemoradiotherapy outcomes for cervical cancer,further research is necessary to substantiate these benefits.

Knockdown of circular RNA (CircRNA)_001896 inhibits cervical cancer proliferation and stemness in vivo and in vitro

Objective:Previous studies indicated that aberrant circular RNA(circRNA)expression affects gene expression regulatory networks,leading to the aberrant activation of tumor pathways and promoting tumor cell growth.However,the expression,clinical significance,and effects on cell propagation,invasion,and dissemination of circRNA_001896 in cervical cancer(CC)tissues remain unclear.Methods:The Gene Expression Omnibus(GEO)datasets(GSE113696 and GSE102686)were used to examine differential circRNA expression in CC and adjacent tissues.The expression of circRNA_001896 was detected in 72 CC patients usingfluorescence quantitative PCR.Correlation analysis with clinical pathological features was performed through COX multivariate and univariate analysis.The effect of circRNA_001896 downregulation on CC cell propagation was examined using the cell counting kit-8(CCK-8)test,clonogenic,3D sphere formation,and in vivo tumorigenesis assays.Results:Intersection of the GSE113696 and GSE102686 datasets revealed an increased expression of four circRNAs,including circRNA_001896,in CC tissues.Fluorescence quantitative PCR confirmed circRNA_001896 as a circular RNA.High expression of circRNA_001896 was considerably associated with lymph node metastasis,International Federation of Gynecologists and Obstetricians(FIGO)stage,tumor diameter,and survival period in CC patients.Proportional hazards model(COX)univariate and multivariate analyses revealed that circRNA_001896 expressions are a distinct risk factor affecting CC patients’prognosis.Cellular functional experiments showed that downregulating circRNA_001896 substantially suppressed CC cell growth,colony formation,and 3D sphere-forming ability.In vivo,tumorigenesis analysis in nude mice demonstrated that downregulating circRNA_001896 remarkably reduced the in vivo proliferation capacity of CC cells.Conclusion:CircRNA_001896 is highly expressed in CC tissues and is substantially related to lymph node metastasis,FIGO stage,tumor size,and survival period in patients.Moreover,downregulating circRNA_001896 significantly inhibits both in vivo and in vitro propagation of CC cells.Therefore,circRNA_001896 might be used as a biomarker for targeted therapy in cervical cancer.

Subgroups of peripheral immune effector cells in cervical cancer patients are more sensitive to radiation therapy than chemotherapy

Background:CD8 positive T lymphocytes and natural killer(NK)cells in the peripheral blood of cervical cancer patients exhibit varying sensitivities to radiotherapy and chemotherapy.Methods:A total of 50 healthy peoples and 60 cervical cancer patients were recruited.The patients with cervical cancer were separated into two groups:radiation and chemotherapy,and blood sample were collected before and after treatment.Data on the proportion of CD8 positive T lymphocytes and NK cells were gathered for analytical evaluation.Results:Compared to healthy individuals,patients with cervical cancer exhibit a reduced proportion of CD8 positive T cells within their peripheral blood.And for patients with cervical cancer,radiation therapy has been found to be more effective than chemotherapy in increasing the proportion of CD8 positive T lymphocytes and NK cells.Conclusions:These results suggest that radiation therapy increases the levels of CD8 positive T lymphocytes and NK cells within the peripheral blood of patients with cervical cancer.The study hypothesis that the changes in the percentage of CD8 positive T lymphocytes may serve as a potential indicator for predicting treatment efficacy.

Artificial intelligence strengthens cervical cancer screening–present and future

Cervical cancer is a severe threat to women’s health.The majority of cervical cancer cases occur in developing countries.The WHO has proposed screening 70%of women with high-performance tests between 35 and 45 years of age by 2030 to accelerate the elimination of cervical cancer.Due to an inadequate health infrastructure and organized screening strategy,most low-and middle-income countries are still far from achieving this goal.As part of the efforts to increase performance of cervical cancer screening,it is necessary to investigate the most accurate,efficient,and effective methods and strategies.Artificial intelligence(AI)is rapidly expanding its application in cancer screening and diagnosis and deep learning algorithms have offered human-like interpretation capabilities on various medical images.AI will soon have a more significant role in improving the implementation of cervical cancer screening,management,and follow-up.This review aims to report the state of AI with respect to cervical cancer screening.We discuss the primary AI applications and development of AI technology for image recognition applied to detection of abnormal cytology and cervical neoplastic diseases,as well as the challenges that we anticipate in the future.

Effectiveness of Co-Testing in Cervical Cancer Screening Program in Macao SAR

Background: Cervical cancer remains a significant public health concern in Macao SAR despite the implementation of a cervical cancer screening program and HPV vaccination. To improve early detection, Macao SAR introduced HPV DNA testing alongside cytology (co-testing) as the primary screening method in 2019. This study evaluates the effectiveness of co-testing in identifying cervical precancerous lesions (CIN2+) compared to cytology alone. Methods: We conducted a retrospective analysis of women aged 30 - 65 years who participated in the routine cervical cancer screening program in Macao SAR Primary Healthcare Centers from 2019 to 2022. Data from over 70,000 women were analyzed, comparing the detection rates of CIN2+ through co-testing and cytology alone. Women with abnormal cytology or positive HPV results were referred for colposcopy. Results: The introduction of co-testing led to a significant increase in the detection of CIN2+, particularly in women with atypical squamous cells of undetermined significance (ASCUS) or negative for intraepithelial lesion or malignancy (NILM) cytology results. Between 2019 and 2022, the percentage of women with ASCUS/NILM and any high-risk HPV (hrHPV) positive who were diagnosed with CIN2+ after colposcopy were 24%, 13%, 10% and 7.5% respectively. This highlights the ability of co-testing to identify high-risk individuals who would have been missed by cytology alone. Discussion: Our findings demonstrate the effectiveness of co-testing in improving the sensitivity of cervical cancer screening in Macao SAR. The inclusion of HPV DNA testing allows for better risk stratification of women with ASCUS/NILM cytology, leading to more targeted referrals for colposcopy and timely detection of precancerous lesions. The initial high positive rate in 2019 (24%) might be attributed to the small sample size and potentially reflects a backlog of undiagnosed cases prior to co-testing implementation. Conclusion: The implementation of co-testing in Macao SAR’s cervical cancer screening program significantly improves the early detection of precancerous lesions, particularly in women with ambiguous cytology results. This proactive approach contributes to reducing cervical cancer morbidity and mortality and improving women’s health outcomes in Macao SAR.

Can we triumph over locally advanced cervical cancer with colossal para-aortic lymph nodes? A case report

BACKGROUND Para-aortic lymph nodes(PALNs)are common sites for the regional spread of cervical squamous cell carcinoma(SCC).CASE SUMMARY We report the case of a 36-year-old woman who presented with cervical SCC with multiple bulky PALNs,largest measured 4.5 cm×5 cm×10 cm.The patient was treated with radical intent with definitive chemoradiation using sequential doseescalated adaptive radiotherapy,followed by maintenance chemotherapy.The patient achieved a complete response;she has been doing well since the completion of treatment with no evidence of the disease for 2 years.CONCLUSION Regardless of the size of PALN metastases of cervical carcinoma origin,it is still treatable(with radical intent)via concurrent chemoradiation.Adaptive radiotherapy allows dose escalation with minimal toxicity.

LncRNA PCGEM1 facilitates cervical cancer progression via miR-642a-5p/KIF5B axis

At present,the role of many long non-coding RNAs(lncRNAs)as tumor suppressors in the formation and development of cervical cancer(CC)has been studied.However,lncRNA prostate cancer gene expression marker 1(PCGEM1),whose high expression not only aggravates ovarian cancer but also can induce tumorigenesis and endometrial cancer progression,has not been studied in CC.The objective of this study was to investigate the expression and the underlying role of PCGEM1 in CC.The relative expression of PCGEM1 in CC cells was detected by real-time PCR.After the suppression of PCGEM1 expression by shRNA,the changes in the proliferation,migration,and invasion capacities were detected via CCK-8 assay,EdU assay,and colony formation assay wound healing assay.Transwell assay and the changes in expressions of epithelial-to-mesenchymal transition(EMT)markers were determined by western blot and immunofluorescence.The interplay among PCGEM1,miR-642a-5p,and kinesin family member 5B(KIF5B)was confirmed by bioinformatics analyses and luciferase reporter assay.Results showed that PCGEM1 expressions were up-regulated within CC cells.Cell viabilities,migration,and invasion were remarkably reduced after the suppression of PCGEM1 expression by shRNA in Hela and SiHa cells.N-cadherin was silenced,but E-cadherin expression was elevated by sh-PCGEM1.Moreover,by sponging miR-642a-5p in CC,PCGEM1 was verified as a competitive endogenous RNA(ceRNA)that modulates KIF5B levels.MiR-642a-5p down-regulation partially rescued sh-PCGEM1’s inhibitory effects on cell proliferation,migration,invasion,and EMT process.In conclusion,the PCGEM1/miR-642a-5p/KIF5B signaling axis might be a novel therapeutic target in CC.This study provides a research basis and new direction for targeted therapy of CC.

Sarcopenia and Anemia Are Predictors of Poor Prognostic in Cervical Cancer Patients

Objective: Evaluate pretreatment sarcopenia and anemia as prognostic factors in women undergoing treatment for cervical cancer (CC) with concurrent chemoradiotherapy (CCRT). Methods: 151 women with CC were analysed in this cohort study. Pretreatment computed tomography (CT) images were analysed to assess skeletal muscle index (SMI). Hazard ratios (HR) and multivariate Cox proportional HR were used to analyse association between low SMI, age, body mass index (BMI), haemoglobin levels, histological type, and International Federation of Gynaecology and Obstetrics (FIGO) stage with PFS and OS. Results: A total of 151 patients were included, 53 (35.1%) presented pretreatment sarcopenia;51 (34%) stage I/II and 100 (66%) stage III/IV. Among those patients in advanced stage (III/IV) 37 (70%) (p = 0.28) were sarcopenic at the beginning of treatment. Sarcopenia was associated with worse progression-free survival (PFS) and overall survival (OS) in our cohort [HR 0.97 (p = 0.01)] [HR 0.73 (p = 0.001)], as well as anemia [HR 0.73 (p = 0.001)] [HR 0.78 (p = 0.001)]. Linear regression models indicated that despite showing no association with age, neutrophil or platelet counts, sarcopenia was associated with pretreatment anemia levels (p = 0.01). After a multivariate analysis, only haemoglobin (anemia) and complete CCRT remained associated with PFS and OS. Sarcopenia and anemia were associated with worse PFS and OS in FIGO stage I/II. Conclusion: Pretreatment sarcopenia was significantly associated with low haemoglobin levels. Anemia and incomplete CCRT were independently associated with poor prognosis in women with CC. Pretreatment sarcopenia, as low SMI, was a predictor of poor prognostic in early stages of CC.

Relationship between Stigma and Marital Satisfaction in Cervical Cancer Patients

Objective: To investigate the status quo of stigma and marital satisfaction of patients with cervical cancer, and analyze the correlation between them, to provide a reference for making intervention plans for patients with cervical cancer. Methods: 216 patients in a third-class first-class hospital in Zhengzhou were investigated by convenient sampling method, using a general information questionnaire, social impact scale, and Olson marriage quality questionnaire. Results: The total stigma score of cervical cancer patients was 73.00 (62.00, 76.00), which was high. The total marital satisfaction score is 36.00 (26.00, 38.00), in the middle level. There was a negative correlation between marital satisfaction and stigma (P Conclusion: The stigma of patients with cervical cancer is at a high level, and their marital satisfaction is at a medium level. Medical staff should give them health education through various channels, pay attention to low-income patients, improve marital satisfaction, and reduce stigma.

Radical Hysterectomy in Cervical Cancer: Patients’ Epidemiological and Clinical Profiles and Perioperative Outcome in Two Referral Hospitals in Cameroon

Background: Cervical cancer (CC) is one of the most frequent cancers and the leading cause of death from gynecological cancer in Low and middle income countries, Cameroon inclusive. Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that reported in the literature. Sensitization on screening and awareness of early symptoms can reverse the situation.

Status Quo of Acceptance of Illness among Reproductive Age Cervical Cancer Patients and Its Influencing Factors

Objective: To explore the status quo of acceptance of illness among reproductive-age cervical cancer patients and its influencing factors, to provide a theoretical basis for the implementation of targeted interventions. Methods: The convenience sampling method was used to investigate 256 reproductive-age cervical cancer patients using the general information questionnaire, Acceptance of Illness Scale, Reproductive Concerns After Cancer Scale, and Medical Coping Style Scale. Results: The total score of the acceptance of illness was (18.03 ± 3.24), and reproductive concerns were (57.02 ± 6.30), among reproductive-age cervical cancer patients. Multivariate analysis showed that age, number of children, income level, treatment method, level of reproductive concerns, and the yield and avoidance dimensions of medical coping style were the main influencing factors on patients’ level of illness acceptance (all P Conclusion: The acceptance of illness levels in reproductive-age cervical cancer patients was low to intermediate, and medical staff should timely identify high-risk groups and take preventive management measures based on influencing factors.

New cheaper human papilloma virus mass screening strategy reduces cervical cancer incidence in Changsha city:A clinical trial

BACKGROUND Cervical cancer is the second leading cause of death in women worldwide,second only to breast cancer.Around 80%of women have been infected with human papillomavirus(HPV)in their lifetime.Early screening and treatment are effective means of preventing cervical cancer,but due to economic reasons,many parts of the world do not have free screening programs to protect women’s health.AIM To increase HPV cervical cancer screening in Changsha and reduce the incidence of cervical cancer.METHODS Cervical cancer screening included gynecological examination,vaginal secretion examination and HPV high-risk typing testing.Cervical cytology examination(ThinPrep cytology test)was performed for individuals who test positive for HPV types other than 16 and 18.Vaginal colposcopy examination was performed for HPV16 and 18 positive individuals,as well as for those who were positive for ThinPrep cytology test.If the results of vaginal colposcopy examination were abnormal,histopathological examination was performed.We conducted a cost-benefit analysis after 4 years.RESULTS From 2019 to 2022,523437 women aged 35-64 years in Changsha city were screened and 73313 were positive,with a 14%positive rate.The detection rate of precancerous lesions of cervical cancer was 0.6%and the detection rate of cervical cancer was 0.037%.Among 311212 patients who underwent two cancers examinations,the incidence rate was reduced by more than half in the second examination.The average screening cost per woman was 120 RMB.The average cost of detecting early cases was 10619 RMB,with an early detection cost coefficient of 0.083.CONCLUSION Our screening strategy was effective and cost-effective,making it valuable for early diagnosis and treatment of cervical cancer.It is worth promoting in economically limited areas.

Economic Burden of Illness of the Cervical Cancer Treatment Protocol in Bangladesh

Background: Cervical cancer is a significant health concern in Bangladesh, with high mortality rates due to limited awareness and costly treatments. The disease stages influence treatment protocols, ranging from surgery and radiotherapy for early stages to chemotherapy and radiation for advanced stages, but survival rates decrease as the cancer progresses. Objective: The objective of this study is to determine the economic impact of the disease and recommend cost-efficient strategies for prevention and treatment. Methods: A population-based, cross-sectional study was conducted with a stratified sample of cervical cancer patients from selected healthcare facilities across Bangladesh. Data collection involved structured interviews and validated questionnaires. The study measured the economic impact, treatment costs, and other related expenses. Quantitative data analysis was performed using SPSS v22, MS-Excel, and R Programming, with Multivariate regression analysis and Post Hoc tests, including the chi-square test, applied to selected indicators. Results: All respondents in the study were female, aged 34 - 75, with 72.3% aged 40 - 50. Most were illiterate (38.6%) and housewives (95.0%). Additionally, 98% were married, 85.10% married before age 18, and 46.50% experienced their first menstruation before age 12. Families typically had a monthly income of 10,000 - 30,000 Taka, spending similar amounts on treatment. Significant relationships were found between educational qualifications, occupation, personal hygiene practices, history of oral contraceptive use, and age of marriage (p Conclusion: The article emphasizes the impact of monthly family income on cervical cancer treatment costs, stressing the need for comprehensive support services to address the financial and emotional burdens faced by patients. Improving access to quality care and implementing measures can enhance outcomes for cervical cancer patients in Bangladesh.

Health promotion and education proposal among Chinese female college students:eliminating cervical cancer is no longer a dream

Cervical cancer is a serious threat to women’s health.Persistent high-risk human papillomavirus(HPV)infection is a necessary factor for cervical cancer development and has become a serious public health threat to women.At present,young women have become a high-risk group for potential HPV infection.HPV vaccination is an effective method to prevent HPV infection and related diseases and is a primary preventive measure for HPV infection-related diseases.This study explores the influencing factors of female college students’willingness to receive HPV vaccination,their ability to understand college students’HPV awareness,their motivation for HPV vaccination,their behavioral skills related to HPV vaccination,their willingness to receive HPV vaccination and their vaccination rate.The aim of this study was to increase the HPV vaccination rate of Chinese female college students through health education programs and thus reduce the incidence of cervical cancer.

Study on the Knowledge of Mothers or Guardians of Girls Aged 9 - 14 from the Langue de Barbarie in Saint-Louis, Senegal about Cervical Cancer and Its Relationship to HPV Vaccination in 2024

Introduction: The relationship between knowledge of HPV and vaccination has been established. The aim of this study was to investigate the knowledge of mothers or guardians of girls aged 9 - 14 about cervical cancer and their attitudes to HPV vaccination. Methodology: This was a descriptive cross-sectional survey. The sample size was calculated using the Schwartz formula and distributed proportionally to the size of the neighbourhood population. Data was collected between 2nd to 19th January 2024 using anonymous questionnaires configured on tablets with Survey 123 software and analysed using R software. Results: A total of 799 people were interviewed. The average age of the respondents was 35.67 years, with a standard deviation of 7.08 and a range of 17 and 49 years. The information channels for cervical cancer were the media (82.8%), health facilities (47.7%) and community intermediaries (23.3%). Only 53.7% had information about the vaccine and 25.5% about the vaccination strategy. The main reason for accepting the vaccine was awareness of the seriousness of cervical cancer (55.1%). Conclusion: It is essential to take stock of knowledge about cervical cancer and attitudes to vaccination to assess the impact of interventions and redirect strategies to improve vaccination coverage. .

Risk assessment and triage strategy of cervical cancer primary screening on HPV integration status:5-year follow-up of a prospective cohort study

Objective:We investigated the relation between man papillomavirus(HPV)integration status and the immediate risk of cervical intraepithelial neoplasia(CIN),as well as the triage strategy based on HPV integration test.Methods:4086 women aged 20 to 65 years in China were enrolled in 2015 for a prospective,population-based,clinical observational study to evaluate the triage performance of HPV integration.Cervical exfoliated cells were collected for HPV testing and cytologic test.If high-risk HPV was positive,HPV integration test was performed at baseline,2-year and 5-year follow-up.Results:At baseline,HPV integration was positively correlated with the severity of cervical pathology,ranging from 5.0%(15/301)in normal diagnosis,6.9%(4/58)in CIN1,31.0%(9/29)in CIN2,70%(14/20)in CIN3,and 100%(2/2)in cervical cancer(P<0.001).Compared with cytology,HPV integration exhibits comparable sensitivity and negative predictive value for the diagnosis of CIN3+,higher specificity(92.8%[90.2%-95.4%]vs.75.5%[71.2%-79.8%],P<0.001)and higher positive predictive value(36.4%[22.1%-50.6%]vs.15.2%[8.5%-21.8%],P<0.001).HPV integration testing strategy yielded a significantly lower colposcopy referral rate than cytology strategy(10.7%[44/410]vs.27.3%[112/410],P<0.001).The HPV integration-negative group exhibited the lowest immediate risk for CIN3+(1.6%)and accounted for the largest proportion of the total population(89.3%),when compared with the normal cytology group(risk,1.7%;proportion,72.7%).Conclusion:As a key molecular basis for the development of cervical cancer,HPV integration might be a promising triage strategy for HPV-positive patients.

Concurrent chemoradiotherapy for cervical cancer： background including evidence-based data, pitfalls of the data, limitation of treatment in certain groups

Concurrent chemoradiotherapy （CCRT） is regarded as the standard treatment for locally advanced uterine cervical cancer （LACC）, including stage Ib2-IVa disease [International Federation of Gynecology and Obstetrics （FIGO） staging]. However, approximately a third of eligible patients in previous studies died of LACC despite receiving CCRT. The therapeutic significance of CCRT alone in stage Ⅲ-IVa disease has not yet been confirmed. Effective treatment of some LACC is beyond the scope of CCRT. The objective of the present review is to highlight some challenging work aimed at overcoming this seemingly intractable disease. CCRT with increased peak concentrations of cisplatin （CDDP）, surgery following CCRT, adjuvant chemotherapy （CT） following CCRT, and neoadjuvant CT followed by CCRT are strategies expected to enhance the therapeutic efficacy of CCRT. If patients with LACC were divided into those with low-risk or high-risk systemic disease or prognoses, novel strategies should be assessed in the group with high-risk disease.

Clinical study of paclitaxel plus cisplatin in the treatment of recurrent cervical cancer

Objective: To observe the efficacy and toxicities of paclitaxel plus cisplatin in the treatment of recurrent cervical cancer. Methods: Twenty-three patients with a diagnosis of recurrent cervical cancer were eligible. Three-weekly chemo- therapy regimen consisted of paclitaxel 135–150 mg/m2 infusion for 3 h on day 1, cisplatin 25 mg/m2 infusion on day 1 to 3. All patients received at least two cycles treatment. Results: The response rates was 47.8%, including CR 2 cases (8.7%), PR 9 cases (39.1%). The major toxicity included neutropenia, nausea vomiting, arthralgia, myalgia and alopecia. Conclusion: Paclitaxel combined with cisplatin is an effective therapy with acceptable adverse reactions for recurrent cervical cancer.

Assessing the Effectiveness of a Cervical Cancer Screening Program in a Hospital-based Study

This study compared HPV testing and liquid-based cytology （LCT） as performance indicators for cervical cancer screening in a hospital-based study. A total of 61,193 outpatients were screened initially by LCT. Samples with screening results showing atypical squamous cells of undetermined significance （ASC-US） or worse were referred for colposcopy, and some samples were tested for high-risk HPV types with the Hybrid Capture II system （HC II）. Data on LCT （n=61,193） and HC II （n=1056） results were analysed. Overall test positivity for LCT was 2.53% using an ASC-US threshold, 3.11% using a low-grade squamous intraepithelial lesion （LSIL） threshold, and 0.67% using a high-grade squamous intraepithelial lesion （HSIL） threshold. A total of 1839 women （84% of the 3893 patients with abnormal cytology） underwent colposcopy-directed biopsy. HPV was positive in 80.3% of women with cervical intraepithelial neoplasia 1 （CIN1）, 88.3% of those with CIN2, 79.2% of women with CIN3 and 50% （2 of 4） of women with invasive cancer. There was a significant increase in the detection of CIN2 or worse with adjunct HPV testing of women with ASC-US and LSIL However, there were detection of CIN2＋ cases no differences in the with adjunct HPV testing of women with HSlI.. The results indicate that HPV testing for HSlL triage should not be recommended in cervical cancer screening.
