Abstract
OBJECTIVE To explore the clinical diagnostic value of DNA image cytometry (DNA-ICM) ploidy analysis in malignant pleural effusion cancer screening, this study analyzed the effect of exfoliated cell smears (ECSs), cell blocks (CBs), and immunochemistry. METHOD A total of 830 cases of pleural effusion were considered for the DNA-ICM ploidy analysis. The ECSs were centrifuged, the CBs were formed, and the DNA-ICM ploidy analysis was carried out in the diagnosis of malignant pleural effusion. Immunochemistry and biopsy was applied to differentiate between benign and malignant pleural effusion and to determine the source of the latter. The sensitivity and specificity differences between the three methods alone and in combination were compared. RESULTS The sensitivity of the DNA-ICM, ECS, and CB methods was 96.28%, 94.93%, and 95.95%, respectively, and the specificity of each method was 86.52%, 87.08%, and 86.14%, respectively. The sensitivity and specificity of the combined diagnosis method were 99.32% and 75.09%, respectively. Among the 22 cases diagnosed as positive in the DNA-ICM ploidy analysis but negative in the ECS and CB analyses, four cases were diagnosed as positive by comprehensive clinical diagnosis. CONCLUSION The sensitivity and specificity of DNA-ICM ploidy analysis are high; the positive detection rate of pleural fluid cytology is effectively increased, and the missed detection rate of cell pathologies is effectively reduced. The combination of the three methods significantly improves the specificity and sensitivity of the diagnosis of malignant pleural effusion, and immunochemistry with CBs can be used to accurately analyze the primary tumor site.

Abstract
In France, recent advances in cervical cancer screening include an organized cervical cancer-screening program and the introduction of HPV testing as a first-line test for women aged 30-65 years. The HPV test, performed on a cervical smear taken by a health professional, could also be performed on a vaginal self-sample in certain indications. The detection kits used to test for HPV should target high-risk HPV, be validated for screening and meet the performance requirements for this indication. Although no longer used as a first-line test in women aged 30-65 years, cytological examination of cervical cells remains important, particularly in the triage of HPV positive women. The interest of other biological techniques, such as HPV genotyping, viral load, cellular expression of p16/Ki-67 proteins and the methylation of cellular or viral genes, still needs to be clarified, but they could help to refine the triage strategy of HPV-positive women and limit the need for colposcopy and unnecessary stress for patients.

Abstract
Polydatin or 3-O-β-d-resveratrol-glucopyranoside (PD), a stilbenoid component of Polygonum cuspicadum (Polygonaceae), has a variety of biological roles. In traditional Chinese medicine, P. cuspicadum extracts are used for the treatment of infections, inflammation, and cardiovascular disorders. Polydatin possesses a broad range of biological activities including antioxidant, anti-inflammatory, anticancer, and hepatoprotective, neuroprotective, and immunostimulatory effects. Currently, a major proportion of the population is victimized with cervical lung cancer, ovarian cancer and breast cancer. PD has been recognized as a potent anticancer agent. PD could effectively inhibit the migration and proliferation of ovarian cancer cells, as well as the expression of the PI3K protein. The malignancy of lung cancer cells was reduced after PD treatments via targeting caspase 3, arresting cancer cells at the S phase and inhibiting NLRP3 inflammasome by downregulation of the NF-κB pathway. This ceases cell cycle, inhibits VEGF, and counteracts ROS in breast cancer. It also prevents cervical cancer by regulating epithelial-to-mesenchymal transition (EMT), apoptosis, and the C-Myc gene. The objective of this review is thus to unveil the polydatin anticancer potential for the treatment of various tumors, as well as to examine the mechanisms of action of this compound.

Abstract
OBJECTIVE The purpose of this study was to provide an updated estimate of the prevalences of different types of human papillomavirus (HPV) in females in Chaoshan District and to establish an internal quality control (IQC) method for excluding false-positive results in HPV detection by using the Levey-Jennings control chart. METHOD HPV types were detected in 23,762 cervical samples by using PCR membrane hybridization. The means and standard deviations (SDs) of the positive rates were calculated, the Levey-Jennings chart was plotted, and the rules for "out of control" and "warning" were established. A set of standardized IQC for HPV DNA tests was developed based on the values and Levey-Jennings charts. RESULT In 466 batches, the positive rate exceeded the 1 + 2SD rule 24 times, but there was no consecutive exceedance, which was considered "in control". When the positive rate exceeded the 1 + 3SD rule 8 times with consecutive exceedance, it was considered "out of control". Further examination revealed that detections showing "out of control" had an undesirable random error, indicating that contamination may occur due to improper operation. CONCLUSION This unique Levey-Jennings control chart is a practical method for eliminating false-positive results in HPV DNA detection and should be widely applicable in molecular diagnostic laboratories.

Abstract
Infection by high-risk human papillomavirus (HPV) causes genetic alterations in host cervical cells with consequent changes in gene expression affecting downstream molecular pathways, leading to the development of cervical cancer. In this exploratory study, we aimed to identify the perturbed cellular pathways during the various stages of cervical carcinogenesis. Total RNA was extracted from three formalin-fixed paraffin-embedded (FFPE) samples each of normal cervix, HPV-infected low-grade squamous intraepithelial lesion (LSIL), high-grade SIL (HSIL) and squamous cell carcinoma (SCC). Gene expression profiling was performed using the 770-gene panel from NanoString nCounter® PanCancer Pathways Panel to identify differentially expressed genes (DEGs) and significantly associated pathways in each stage of cervical cancer development. We identified 121 DEGs involved in cervical carcinogenesis. In the transformation from normal cells to LSIL, the MAPK, transcriptional misregulation and JAK-STAT pathways are implicated, while IL1B may promote inflammation and indirectly activates MMP9, resulting in collagen breakdown and cell migration. The cell cycle - apoptosis pathway with upregulation of E2F1 and MCM2, and DNA repair genes BRCA2-BRIP1 and FANCA are crucial during the progression from LSIL to HSIL. In the final stage of progression to SCC, the cell cycle and signaling pathways, as well as upregulation of c-MYC appear essential. In conclusion, archived FFPE-derived tissue samples are a valuable resource for gene expression profiling. The postulated dysregulated pathways and genes provide a guide of the molecular mechanisms that may be involved in the development of HPV-associated cervical cancer, for further investigation and validation studies.

Abstract
Background: Chinese square dance has become well known worldwide in recent years, and most participants are women who dance with a group in their communities. In particular, middle-aged women may have physical and mental health problems, and participating in square dance may increase women's positive subjective well-being and decrease their negative emotions, which may improve their health over the long term. In addition, participating in square dance can promote group cohesion. Our study aimed to examine the relationship between the subjective exercise experience of participating in square dance and group cohesion and whether some variables (e.g., age, education, duration, income level, and work) play a role as mediators in the association with subjective exercise experience and group cohesion. Methods: In total, 1,468 Chinese women from 31 provinces and 82 cities participated in this study by completing an online questionnaire. The questionnaire consisted of a subjective exercise experience questionnaire and a group environment questionnaire. We analyzed the collected data and built a statistical model. Results: (a) Square dance satisfied women's physical and psychological needs partly; (b) positive well-being (PWB) was positively correlated with group cohesion, and fatigue was negatively correlated with group cohesion; and (c) the income level was a partial mediator of the relationship between group cohesion and subjective exercise experience. Conclusion: Chinese women have different motivations for participating in square dance. Because this activity can help meet women's physical and psychological needs, an increasing number of individuals worldwide participate in square dance. As women's subjective well-being increases, group cohesion increases, and vice versa. Moreover, the subjective exercise experience remains a significant predictor of group cohesion after including income level as a mediator, suggesting that the model indicates partial mediation.

Abstract
Cervical cancer remains a concern worldwide, and cervical cancer screening plays an important role in reducing the burden of this disease. Although cytology is still the main strategy for cervical cancer screening, it has gradually changed to human papillomavirus testing. The specificity of human papillomavirus testing is lower than that of cytology, which leads to an increased rate of colposcopy after positive results. To decrease colposcopic examinations, an efficient triage method is needed for human papillomavirus screening. New biomarkers have been developed and evaluated for primary screening and triage of abnormal cytology or human papillomavirus-positive results. Their sensitivity and specificity were estimated and compared with those of cytology. In the present study, the following new techniques were examined: p16/Ki67 dual staining, DNA methylation, micro-ribonucleic acid, chromosomal abnormalities, Claudins and DNA ploidy. Evaluation studies of p16/Ki67 dual staining and DNA methylation were more advanced than those of other options. When p16/Ki67 dual staining was used for triage for human papillomavirus testing, the sensitivity of 2 or greater cervical intraepithelial neoplasia (CIN2+) detection was higher than that of cytology without decreased specificity. Although there are several types of DNA methylation, sensitivity and specificity were moderate for detecting CIN2+. S5 classifier is a commercialized product that consists of viral methylation, and high sensitivity with decreased specificity has been reported. Considering its combination with self-sampling, DNA methylation is a highly anticipated technique along with human papillomavirus testing for the next generation of cervical cancer screening. However, the backgrounds for cervical cancer screening differ among countries and further study is needed to identify the best available method.

Abstract
Polydatin, an active ingredient from the roots of Polygonum cuspidatum, is considered to have protective effects on the cardiovascular system and liver. In this study, we demonstrated that polydatin has antitumor activity against human cervical cancer. Polydatin efficiently inhibited cervical cancer cell proliferation by regulating cell cycle-related proteins including p21, p27, CDK2, CDK4, Cyclin D1, and Cyclin E1. Furthermore, polydatin suppressed cell invasion and migration by regulating epithelial-mesenchymal transition (EMT) markers, including E-cadherin, N-cadherin, Snail and Slug. The c-Myc, as a proto-oncogene, is considered to be closely associated with the proliferation and metastasis of tumor cells. After polydatin treatment, the protein expression of c-Myc showed a significant decrease. Based on these data, we overexpressed c-Myc in cervical cancer cells and observed that the overexpression of c-Myc rescued the inhibitory effect of polydatin on cell proliferation and metastasis. These results indicated that polydatin can inhibit cell proliferation and metastasis through suppressing the c-Myc expression in human cervical cancer.

Abstract
Cervical cancer is a serious global health problem. The objective of this study was to provide a suitable cytology-based cervical screening method in women of different ages in primary hospitals.This study was a retrospective cohort study that included 9765 women who underwent primary cytology-based cervical screening and were grouped by age (35-44, 45-54, and 55-64 years old). Patients with abnormal cytology on the primary cervical thin-prep cytologic test (TCT) were advised to undergo triage human papillomavirus (HPV) test. Furthermore, patients with positive outcomes of the 2 indices underwent cervical tissue biopsy. The positive rate of TCT and HPV was compared among the 3 defined age groups. The sensitivity, specificity, and positive predictive value of TCT and HPV were assessed.In total, 2.5% (241/9765) of women had atypical squamous cells of undetermined significance or worse by TCT. High-risk (HR)-HPV infection was found in 70 triage participants. Neoplastic changes were confirmed in 95 patients (95/437, 21.7%) by biopsies. Among the different age groups, the positive rate of abnormal cytology was significantly different (P = .003), and the positive rate of HR-HPV was similar (P = .299). The sensitivity of initial TCT testing to detect intraepithelial neoplasia was higher than that of triage HPV testing, whereas the specificity, the positive predictive value of triage HPV testing was higher than that of TCT. The Youden index of HPV testing was higher than that of TCT detection in the 3 age groups, namely 0.582 versus 0.432, 0.553 versus 0.228, and 0.416 versus 0.332, respectively.The results of this study indicate that TCT testing is suitable as a cervical cancer screening method for women ≥35 years old in primary hospitals. Triage testing for women with HR-HPV has a high negative predictive value, reduces the rate of misdiagnosis, seems to be an excellent triage method for repeat atypical squamous cells of undetermined significance, and reduces the number of referral colposcopies preventing unnecessary overtreatment. The results of this study provide a crucial foundation for a unified guideline cervical cancer screening for primary health care institutions.

[PMID: 32308477 PMCID: PMC7132552 DOI: 10.2147/cmar.s237490] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 03/13/2020] [Indexed: 02/01/2023] Open
Abstract
Objective To assess the clinical value of the PCR-reverse dot blot human papillomavirus genotyping test during follow-up of patients with CIN grade 2 or worse (CIN 2+). Methods Four hundred patients with CIN 2+ receiving treatment from January 2008 to January 2017 were included in our study. Postoperative follow-up procedures comprised HPV examination and cervical cytology every 3–6 months for the first 2 years and then followed up every 6–12 months. A pathology examination was performed when there was a positive funding for HPV 16/18 or an abnormal ThinPrep cytology test (TCT) with or without positive for HR-HPV according to the American Society for Coloscopy and Cervical Pathology (ASCCP) guidelines. Results The median follow-up period was 27.10±12.47 months (ranging from 3 to 50 months). During follow-up, 12.00% (48/400) of the women developed residual/recurrent disease. The highest risk in CIN 2+ and CIN 3+ residual/recurrence was HPV-16/-18 (hazard ratio (HR)=12.898, 95% CI= 6.849–24.289; HR= 20.726, 95% CI= 9.64–44.562, respectively). Among the different follow-up methods, type-specific (TP) HR-HPV persistent infection showed the highest cumulative incidence risk (CIR) (84.62%, 95% CI=73.29–95.94) and HR (5.38, 95% CI= 2.596–11.149) during the 4-year follow-up period. At the CIN 2+ and CIN 3+ endpoints, TP-HPV testing had relatively high sensitivity (84.62%, 95% CI=73.29–95.94 and 89.28%, 95% CI= 77.83–100.00, respectively) and specificity (78.07%, 95% CI= 72.70–83.44 and 75.73%, 95% CI= 70.30–81.17, respectively). However, at the CIN 2+/CIN 3+ endpoint, TCT follow-up had a sensitivity of 60.42%/62.16% (95% CI=46.58–72.25/46.54–77.79) and specificity of 90.18%/88.72% (95% CI=86.95–93.41/85.35–92.10). Conclusion TP HR-HPV follow-up can provide a reliable and sensitive clinical reference for CIN 2+ postoperative patients.

J Gynecol Oncol 2019; 30:e29. [PMID: 30887754 PMCID: PMC6424850 DOI: 10.3802/jgo.2019.30.e29] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 10/24/2018] [Accepted: 11/13/2018] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVE To evaluate the polymerase chain reaction (PCR)-reverse-dot-blot (RDB) human papillomavirus (HPV) genotyping test as a feasible assay for the cervical cancer primary screening. METHODS In a hospital-based cohort, a total of 21,568 women were voluntarily enrolled from March 2009 to November 2016 for evaluating the 3 current cervical cancer screening strategies: co-test, cytology primary and high-risk HPV (HR-HPV) primary by using PCR-RDB HPV genotyping and liquid-based cytology (thinprep cytologic test [TCT]). Women with HR-HPV infection and/or abnormal cytology were referred for colposcopy, and the biopsy or conization was performed according to the American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines. RESULTS Overall, 18.20% (3,935/21,568) of the women were detected as HR-HPV-positive, 5.04% (1,088/21,568) were diagnosed with cervical intraepithelial neoplasia 2 or higher (CIN2+), and 3.43% (739/21,568) with CIN3+. The cumulative incidence rates for CIN2+/CIN3+ in patients with HPV-16/18-positive were 48.28%/37.20%, while they were 0.86%/0.38%, 0.30%/0.15% and 0.18%/0.09% in cytology-negative, HR-HPV-negative and co-test-negative population, respectively. Using CIN2+ and CIN3+ as the observed endpoints, the sensitivity and negative predictive value (NPV) of HR-HPV genotyping as a primary screening tool were 90.99%/99.49% and 91.57%/99.80%. Moreover, using HR-HPV genotyping primary screening could detect the same more CIN2+/CIN3+ cases in baseline-detection as co-testing (990/700 vs. 991/701) and far more than cytology primary screening (903/656, p<0.05). It also achieved the lowest misdiagnosis rate (8.01%/5.02%). Although HPV genotyping primary screening required an increased number of colposcopies (2.75/3.89 per CIN2+/CIN3+ case), it yielded an acceptable rate. CONCLUSIONS The PCR-RDB HPV genotyping test is a cost-effective and beneficial cervical cancer primary screening for hospital-based opportunistic screening.

Abstract
Cervical cancer is one of the most prevalent female cancer types in developing countries. ThinPrep cytological test (TCT) and human papillomavirus (HPV) detection are canonical screening methods for cervical cancer currently. However, there are limitations to these techniques. The aim of the present study was to identify efficient and practical methods for the screening of cervical intraepithelial neoplasia (CIN) and carcinoma. Residual PreservCyt specimens were obtained from 1,000 women who were admitted between August 2013 and December 2015. TCT, human telomerase RNA component (h-TERC) fluorescent in situ hybridization (FISH), MYC-specific FISH and surface plasmon resonance (SPR)-HPV genotyping were performed, followed by histopathology for those patients with positive results in any of the four tests. As a result, 106, 64, 56 and 112 patients were positive in the TCT, h-TERC, c-MYC and SPR-HPV tests, respectively, resulting in 213 being scheduled for histopathology; inflammation was identified in 159 patients, CIN I in 31, CIN II in 14, CIN III in seven and invasive cervical cancer in two patients. Using histopathology as the gold standard, TCT exhibited the highest sensitivity (87.04%), while h-TERC analysis had the highest specificity (81.76%). Parallel tests demonstrated that the Youden's index of TCT + h-TERC was the highest (0.49), while the serial analysis reported that TCT + HPV had the highest Youden's index (0.53) compared with any of the biomarkers alone (TCT, 0.50; HPV, 0.29; h-TERC, 0.47). In conclusion, dual positive TCT and HPV may be an efficient approach for basic screening of cervical lesions. h-TERC amplification may serve as an auxiliary test to improve the specificity.

Abstract
PURPOSE This study assessed the clinical significance of c-myc gene copy number gain detected by fluorescence in situ hybridization (FISH) in the prediction of cervical intraepithelial neoplasia (CIN) progression. METHODS We retrospectively investigated 140 Thinprep cytologic test (TCT) specimens that were histopathologically diagnosed with various stages of cervical neoplasia or malignancy. The specimens were subjected to TCT, human papillomavirus (HPV) testing, and FISH analysis with a c-myc-specific probe. The diagnostic reliability of these methods in determining progression was assessed according to sensitivity, specificity, and κ coefficients. RESULTS The gene copy number gain of c-myc was significantly higher in the cervical lesion of advanced histologic grade (p < 0.001). For CIN2+ lesions, the sensitivities of TCT, HPV DNA testing, and FISH analysis were 72.3, 92.1, and 64.5%, respectively; the specificities were 81.3, 57.8, and 93.8%, respectively (p < 0.001). The κ coefficients between the c-myc gene test and either the TCT or the HPV DNA test were 0.538 and 0.399, respectively (p < 0.001). CONCLUSIONS FISH analysis of the c-myc oncogene could be a useful adjunct screening method for the early diagnosis of high-grade cervical lesions. Moreover, c-myc may be a new molecular biomarker for the early diagnosis of cervical lesion progression.
