Estimation of economic burden throughout course of cervical squamous intraepithelial lesion and cervical cancer in China:A nationwide multicenter cross-sectional study

Objective: Cervical squamous intraepithelial lesion(SIL) and cervical cancer are major threats to females' health and life in China, and we aimed to estimate the economic burden associated with their diagnosis and treatment.Methods: A nationwide multicenter, cross-sectional, hospital-based survey was conducted in 26 qualified hospitals across seven administrative regions of China. We investigated females who had been pathologically diagnosed with SIL and cervical cancer, and included five disease courses(“diagnosis”, “initial treatment”,“chemoradiotherapy”, “follow-up” and “recurrence/progression/metastasis”) to estimate the total costs. The median and interquartile range(IQR) of total costs(including direct medical, direct non-medical, and indirect costs), reimbursement rate by medical insurance, and catastrophic health expenditures in every clinical stage were calculated.Results: A total of 3,471 patients in different clinical stages were analyzed, including low-grade SIL(LSIL)(n=549), high-grade SIL(HSIL)(n=803), cervical cancer stage ⅠA(n=226), ⅠB(n=610), ⅡA(n=487), ⅡB(n=282), Ⅲ(n=452) and Ⅳ(n=62). In urban areas, the estimated total costs of LSIL and HSIL were $1,637.7(IQR:$956.4-$2,669.2) and $2,467.1(IQR:$1,579.1-$3,762.3), while in rural areas the costs were $459.0(IQR:$167.7-$1,330.3) and $1,230.5(IQR:$560.6-$2,104.5), respectively. For patients with cervical cancer stage ⅠA,ⅠB, ⅡA, ⅡB, and Ⅲ-Ⅳ, the total costs were $15,034.9(IQR:$11,083.4-$21,632.4), $19,438.6(IQR:$14,060.0-$26,505.9), $22,968.8(IQR:$16,068.8-$34,615.9), $26,936.0(IQR:$18,176.6-$41,386.0) and $27,332.6(IQR:$17,538.7-$44,897.0), respectively. Medical insurance covered 43%-55% of direct medical costs for cervical cancer patients, while the coverage for SIL patients was 19%-43%. For most cervical cancer patients, the expense was catastrophic, and the extent of catastrophic health expenditure was about twice large for rural patients than that for urban patients in each stage.Conclusions: The economic burden of SIL and cervical cancer in China is substantial, with a significant proportion of the costs being avoidable for patients with LSIL. Even for those with medical insurance, catastrophic health expenditures are also a major concern for patients with cervical cancer, particularly for those living in rural areas.

Biomarkers Expression in Cervical Cancer and High Grade Squamous Intraepithelial Lesions

Objectives: The finding of new prognostic factors in human cervix cancer is necessary to improve present conventional treatments. The aim of the present study was to determine the expression and evaluate the prognostic value of hypoxia-inducible factor-1(HIF-1α), vascular endothelial growth factor (VEGF) and eritropoyetin receptor (EpoR) in cervix cancer stages IIA-IIB and in preinvasive high grade squamous intraepithelial lesions (HSIL) Methods: The study included 70 patients with cervix cancer, FIGO stages IIA-IIB, 28 patients with HSIL and normal cervix (n = 28). HIF-1α, VEGF and EpoR expression were analyzed in tissue samples by immunohistochemistry using commercial antibodies. Expression and overexpression of the tumor markers were quantified according to German Immunoreactive Score. Results: HIF-1α, EpoR and VEGF overexpression was detected in 30%, 37% and 51% of cancer patients respectively. Patients with HSIL showed enhanced expression only of EpoR and VEGF (39.2% and 71.4%) while VEGF was overexpressed in 21% of the specimen. No correlation was found between VEGF and EpoR with disease-free overall survival (OS), tumor recurrences or prognostic factors. Only overexpression of HIF-1 was associated with less median survival measured up to 24 months, unless it was not maintained a long time. Conclusion: Although any of the markers could be considered as independent prognostic factor for cervix cancer patients, our data showed a significant increase in their expression from the premalignant lesion up to the invasive stages of tumor progression.

Clinical significance of colposcopy on screening cervical intraepithelial neoplasia in cytological negative and smooth cervices

Objective： The aim of the study was to evaluate the clinical value of the video colposcopy in screening cervical intraepithelial neoplasia （CIN） in cytological negative and smooth cervices by optically gynecological examination. Methods： The 1050 women, whose cervices had been shown smooth and cytological negative by optical examine, were examined with electronic colposcopy in gynecological clinic, and biopsy was taken when the double abnormality of aceto-white epithelium and iodine negative, and other abnormal images were shown. A retrospective analysis of these cases was performed. Re. suits： （1） The 514 samples from 458 cases, including 458 samples of abnormal tissues under colposcopy and 56 samples of polyp or polypoid tumors by optically, were examined by biopsy. Among them, 68 samples were found to be CIN, including 11 cases of CINII/CINIII; （2） The 72 of 1050 cases showed the double-abnormality of aceto-white epithelium and iodine nega- tive. Among them, 64 cases were CIN determined by biopsy. And the positive predictive value of the double-abnormality of aceto-white epithelium and iodine negative under colposcopy was 88.9%, with a false negative rate of 3.3%; （3） Among 458 women examined by biopsy, only one of 350 samples from cervical polyp tissue was CIN （0.3%）, while 67 of 164 samples from the tissues with abnormal colposcopic images were found to be CIN （40.9%）, indicating the close relation between abnormal colposcopic findings and CIN; （4） The results of age-distribution analysis showed that, in the 164 cases with abnormal features under colposcopy, the incidence of double abnormality of aceto-white epithelium and iodine negative was higher in the age of sexual activity, just the same as the age distribution feature of CIN; while single abnormality of iodine negative appeared more in the age of over 50 years. Conclusion： Abnormal features displayed by colposcopy, especially the double abnormality of aceto-white epithelium and iodine negative, has an important significance for the screening of cervical precancerous lesions such as CIN. For this purpose, colposcopy examination is necessary even for the cases of cytological negative and smooth cervices.

The Relationship between p53 Expression and Human Papillomavirus in Premalignant and Malignant Uterine Cervical Lesions

Objective: We aimed to retrospectively examine a series of premalignant and malignant cervical tissues to study a high-risk HPV 16 infection that, among cervical tissue lesions, carries the greatest risk of conversion to cancer, and the presence of p53 protein immunoreactivity, a tumor suppressor gene product. Methods: Paraffin blocks were studied via immunohistochemical (IHC) method to explore the presence of HPV 16 in 59 premalignant and malignant cervical lesions as well as immunoreactivity of the p53 oncoprotein, the most common cellular tumor suppressor gene product in human cancers. Results: In our series, mutant p53 positivity rate was 35.3% for low-grade CIL, 40% for high-grade CIL, and 46.8% for invasive carcinoma cases. Immune staining for high-risk HPV 16 type yielded a positive staining rate of 47% in low-grade CIL, 80% in high-grade CIL, and 50% in invasive carcinoma. Conclusion: The results of our study indicate a progressive increase in p53 oncoprotein reactivity from cervical intraepithelial neoplasia to invasive carcinoma. This suggests the clinical importance of p53 immunoreactivity in dysplastic progression and neoplastic transformation. HPV is the most commonly encountered oncogenic type in cervical lesions, especially in high-grade CIL and invasive carcinomas. Results of the previous reports suggest that HPV-positive carcinomas release wild type p53 and HPV-negative ones release mutant type p53 were not confirmed by our results, which indicated a mutant type p53 reactivity in HPV- 16 positive carcinoma cases.

Triage for management of cervical high-grade squamous intraepithelial lesion patients with positive margin by conization： a retrospective analysis

The objective of this study is to guide a triage for the management of cervical high-grade squamous intraepithelial lesion （HSIL） patients with positive margin by conization. Clinico-pathological data of HSIL patients with positive margin by conization were retrospectively collected from January 2009 to December 2014. All patients underwent secondary conization or hysterectomy within 6 months. The rate of residual lesion was calculated, and the factors associated with residual lesion were analyzed by univariate and multivariate analyses. Among a total of 119 patients, 56 （47.06%） patients presented residual HSIL in their subsequent surgical specimens, including 4 cases of invasive cervical carcinoma （3 stage IA1 and 1 stage IA2 patients）. Univariate analysis showed that patient age 〉 35 years （P = 0.005）, menopausal period 〉 5 years （P = 0.0035）, and multiple- quadrant involvement （P=0.001） were significantly correlated with residual disease; however, multivariate analysis revealed that multiple-quadrant involvement （P=0.001; OR, 3.701; 95%CI, 1.496-9.154） was an independent risk factor for residua! disease. Nearly half of HSIL patients with positive margin by conization were disease-free in subsequent surgical specimens, and those with multiple positive margins may consider re- conization or re-assessment.

Large pelvic mass arising from the cervical stump: A case report

BACKGROUND A large cervical cyst with a cervical high-grade squamous intraepithelial lesion arising from the cervical stump is rare.After supracervical hysterectomy,there is a risk of various lesions occurring in the cervical stump.We review the types and characteristics of cervical stump lesions and compare total hysterectomy with subtotal hysterectomy.Gynecologists should choose the most suitable surgical method based on both the patient’s condition and wishes.If the cervix is retained,patients require a close follow-up.CASE SUMMARY A 57-year-old woman was admitted to the Gynecology Department for a large pelvic mass.Her chief complaint was abdominal distention for two months.She had undergone subtotal supracervical hysterectomy for leiomyoma 14 years prior.Abdominal ultrasonography detected a 9.1 cm×8.5 cm×8.4 cm anechoic mass with silvery fluid in the pelvic cavity and high-risk human papilloma virus 53(HPV53)was positive.The admission diagnosis we first considered was a pelvic mass mimicking carcinoma of the cervical stump.We performed a laparotomy and a rapid frozen biopsy was suggestive of a fibrous cyst wall coated with a high squamous intraepithelial lesion.The pelvic mass was removed,and a bilateral adnexectomy was implemented.Final pathology confirmed that the pelvic mass was a large inflammatory cyst with a cervical high-grade squamous intraepithelial lesion.After successful intervention,the patient was discharged one week after surgery and there was no recurrence of the vaginal stump at 43 mo.CONCLUSION When addressing benign uterine diseases,gynecologists should pay adequate attention to retaining the cervix.If the cervix is retained,patients require a close follow-up.

Prevalence of Cervical Human Pappillomavirus Infection in Awka, Nigeria

Prevalence of cervical Human Papillomavirus infection and type distribution vary with different environments. Knowledge of this will help in some cervical cancer interventions such as vaccine administration. This study aimed at determining the prevalence of cervical HPV infection among women attending a tertiary hospital in Awka, Nigeria. To evaluate cervical HPV Infections, cervical samples were collected over a period of 1 year from 405 consenting women. Multiplex PCR and cytology were used in the study. Semi-structured questionnaire was used to obtain the demographic characteristics of the participants. Statistical analysis was done using IBM SPSS statistics version 21. The findings showed that of the 405 women, 387 (94.4%) had normal cytology, and 18 (4.4%) had Low-grade Squamous Intraepithelial Lesion (LSIL). There was no High-grade Squamous Intraepithelial Lesion (HSIL). HPV prevalence of (79) 19.5% was obtained overall in the 405 women, (75 of 387) 19.4% with normal cytology, (4 of 18) 22.2% with LSIL. Age specific prevalence peaked at age group 30 - 39 and a second peak at 60 - 69. HPV types obtained were HPV 16 31 (7.7%), HPV 18 24 (5.9%), HPV 35 3 (0.7%), HPV 33 9 (2.2%), HPV 68 3 (0.7%) and multiple infections (9) 2.2%. HPV 16 was the only type found in LSIL. Regular HPV typing and screening of our women for HPV infection and Pap’s smear can go a long way in the reduction of cervical cancer.

Correlative analysis between abnormal cervical cytology and pathology of vaginoscopic biopsy or conization

Objectives: To evaluate the predictive value of cervical intraepithelial neoplasia (CIN)III/ carcinoma in situ (CIS) by correlating analysis between abnormal cervical cytologic findings and pathological diagnosis of vaginoscopic biopsies or conization.Methods: Routine cervical cytology screening was performed in 31,634 cases by fluid-based thin-layer method (ThinPrep cytology test, TCT), 948 patients had both abnormal squamous cell appearance by TCT and pathological diagnosis of vaginoscopic biopsies and /or cervical conization. The predictive value of CINIII/CIS were studied retrospectively by correlating analysis of different cytology abnormalities and pathology diagnosis.Results: Cytologically, 1,260 out of 31,634 TCT tests showed abnormal squamous cells appearance, including atypical squamous cell of undetermined significance (ASCUS) 675 cases(2.13%), low squamous intraepithelial lesion (L-SIL) 379 cases(1.20%), high squamous intraepithelial lesion (H-SIL)176 cases(0.56%),cancer 30 cases (0.09%). Among 948 patients with pathological diagnosis, there were CINII-III in 70 cases(7.38%) and CINIII/CIS in 56 cases.(5.91%). The relative risks (RR) of different precancerous TCT results in predicting CIN III/CIS validated by pathology are as follow: AUSCUS 14.7% (95% confidence interval (CI) 8.0-27.0), Lsil 13.9% (95% CI 6.3-30.9), Hsil 126.1 (95% CI 60.6-218.6). The RR of AUSCUS group is not significantly different from that of L-SIL group(P =0.951). However, the RR of CINⅢ/CIS morbidity between the H-SIL or cancer group and the ASCUS or L-SIL group are significantly different (all P value <0.01).Conclusion: Vaginoscopic biopsy could verify pathological CINⅡ-Ⅲ and CINⅢ/CIS from cases with abnormal TCT results. There is significantly greater risk of being CINⅢ/CIS validated by vaginoscopic biopsy in the H-SILpatients,while ASCUS and L-SIL group have the coequal risk.

Expression and clinical significance of Klotho and Beclin1 in cervical squamous carcinoma

Objective:To detect the expression of klotho and beclin1 protein in chronic cervicitis, low grade squamous intraepithelial lesion (LSIL) group, high grade squamous intraepithelial lesion (HSIL) group and cervical squamous cell carcinoma (SCC) group.Methods:Immunohistochemical technique (Envision) was used to detect the expression of Klotho and Beclin1 proteins in each study group. The correlation between the expression of the above two proteins and the pathological features of SCC and the expression of the two proteins in SCC were analyzed.Results: The positive expression rates of Klotho protein in chronic cervicitis group, LSIL group, HSIL group and SCC group were 95%, 92.86%, 65.38%, 27.90%, respectively. The positive rates of Beclin1 protein in chronic cervicitis group, LSIL group, HSIL group were 25.0%, 28.57%, 38.46% and 74.42%, respectively. The differences were statistically significant. The expression of Klotho and Beclin1 in SCC was correlated with the degree of tumor differentiation, but not with the age, figo stage, lymph node metastasis, tumor size, depth of invasion and vessel invasion, but not with the age of the patient, tumor figo stage, lymph node metastasis, tumor size, depth of invasion and vessel invasion. There was no correlation between the expression of klotho and beclin1 in SCC tissues.Conclusion: The abnormal expression of klotho and beclin1 may be related to the development, invasion and metastasis of cervical squamous cell carcinoma.
