Abstract
Previous studies show that glycogen synthase kinase 3β (GSK3B) plays an important role in tumorigenesis. However, its role in cervical cancer is unclear. The present study silenced GSK3B with siRNAs and/or chemical inhibitors to determine its role in HeLa cervical cancer cell proliferation and migration as well as in xenograft tumor growth. Cell Counting Kit (CCK)-8 and 5-ethynyl-2'-deoxyuridine (EdU) assays were used to determine cell survival and proliferation. Scratch and Transwell® assays were used to evaluate cell migration. Xenograft tumors were used to evaluate the effect of GSK3B on tumor growth. Transcriptomic sequencing was used to clarify the mechanisms underlying the foregoing processes. Public databases and clinical specimens showed that GSK3B was upregulated in cervical cancer tissues and correlated with poor prognosis. In vitro experiments indicated that GSK3B inhibition reduced cell viability, proliferation, and migration. In vivo experiments demonstrated that GSK3B inhibition slowed xenograft tumor growth. Transcriptomic sequencing revealed that GSK3B inhibition modulated the phosphatidylinositol 3-carboxykinase (PI3K)/protein kinase B (Akt) and extracellular matrix (ECM)-receptor interaction signaling pathways. GSK3B inhibition decreased the protein levels of phosphorylated PI3K and Akt and the levels of mesenchymal markers but increased those of epithelial markers. An activator of the PI3K/Akt signaling pathway counteracted the suppressive effects of GSK3B inhibition on HeLa cell viability and proliferation and on PI3K/Akt signaling. Our data suggested that GSK3B regulated cervical cancer cell proliferation and migration by modulating the PI3K/Akt signaling pathway and epithelial-to-mesenchymal transition (EMT).

Development and validation of a radiomics-based nomogram for the prediction of postoperative malnutrition in stage IB1-IIA2 cervical carcinoma. Front Nutr 2023; 10:1113588. [PMID: 36819703 PMCID: PMC9936189 DOI: 10.3389/fnut.2023.1113588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 01/12/2023] [Indexed: 02/05/2023] Open
Abstract
Objective In individuals with stage IB1-IIA2 cervical cancer (CC) who received postoperative radiotherapy ± chemotherapy (PORT/CRT), the interaction between sarcopenia and malnutrition remains elusive, let alone employing a nomogram model based on radiomic features of psoas extracted at the level of the third lumbar vertebra (L3). This study was set to develop a radiomics-based nomogram model to predict malnutrition as per the Patient-Generated Subjective Global Assessment (PG-SGA) for individuals with CC. Methods In total, 120 individuals with CC underwent computed tomography (CT) scans before PORT/CRT. The radiomic features of psoas at L3 were obtained from non-enhanced CT images. Identification of the optimal features and construction of the rad-score formula were conducted utilizing the least absolute shrinkage and selection operator (LASSO) logistic regression to predict malnutrition in the training dataset (radiomic model). Identification of the major clinical factors in the clinical model was performed by means of binary logistic regression analysis. The radiomics-based nomogram was further developed by integrating radiomic signatures and clinical risk factors (combined model). The receiver operating characteristic (ROC) curves and decision curves analysis (DCA) were employed for the evaluation and comparison of the three models in terms of their predictive performance. Results Twelve radiomic features in total were chosen, and the rad-score was determined with the help of the non-zero coefficient from LASSO regression. Multivariate analysis revealed that besides rad-score, age and Eastern Cooperative Oncology Group performance status could independently predict malnutrition. As per the data of this analysis, a nomogram prediction model was constructed. The area under the ROC curves (AUC) values of the radiomic and clinical models were 0.778 and 0.847 for the training and 0.776 and 0.776 for the validation sets, respectively. An increase in the AUC was observed up to 0.972 and 0.805 in the training and validation sets, respectively, in the combined model. DCA also confirmed the clinical benefit of the combined model. Conclusion This radiomics-based nomogram model depicted potential for use as a marker for predicting malnutrition in stage IB1-IIA2 CC patients who underwent PORT/CRT and required further investigation with a large sample size.

Abstract
Circular RNAs (circRNAs), a new class of non-coding RNAs, have been recently confirmed to regulate cell development, functions and certain types of pathological responses. In addition, it has been proved that circ_0000190 can serve as a tumor suppressor in several cancers. However, the underlying mechanism and biological functions of it in cervical cancer (CC) remain to be revealed. In our study, relative expression of indicated molecules was detected by RT-qPCR analysis. Loss-of-function and gain-of-function experiments were conducted to detect cell functions. Mechanism experiments including RIP assay, luciferase reporter assay and pull down assay were applied to verify the interaction among the indicated molecules. Overexpressed circ_0000190 attenuated CC progression in vitro and in vivo. Circ_0000190 functioned through the modulation of miR-1252-5p/EIF4EBP2 axis. Rescue experiments found that miR-1252-5p overexpression or EIF4EBP2 knockdown could reverse the influence on CC cells caused by circ_0000190 overexpression. Interestingly, it was found that EIF4EBP2 could bind to proto-oncogene eIF4E and prevent eIF4E from forming into complex and functioning. Circ_0000190 served as a tumor suppressor in CC and down-regulated circ_0000190 expression could weaken the binding ability of EIF4EBP2 to eIF4E thus leading to CC tumorigenesis. In our investigation, a novel tumor suppressive gene circ_0000190 was recognized, which could be treated as a promising biomarker for the diagnosis of CC.

Abstract
Background Increasing evidence suggests that tumour necrosis factor (TNF) family genes play important roles in cervical cancer (CC). However, whether TNF family genes can be used as prognostic biomarkers of CC and the molecular mechanisms of TNF family genes remain unclear. Methods A total of 306 CC and 13 normal samples were obtained from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases. We identified differentially expressed TNF family genes between CC and normal samples and subjected them to univariate Cox regression analysis for selecting prognostic TNF family genes. Least absolute shrinkage and selection operator (LASSO) regression and multivariate Cox regression analyses were performed to screen genes to establish a TNF family gene signature. Gene set enrichment analysis (GSEA) was performed to investigate the biological functions of the TNF family gene signature. Finally, methylation and copy number variation data of CC were used to analyse the potential molecular mechanisms of TNF family genes. Results A total of 26 differentially expressed TNF family genes were identified between the CC and normal samples. Next, a TNF family gene signature, including CD27, EDA, TNF, TNFRSF12A, TNFRSF13C, and TNFRSF9 was constructed based on univariate Cox, LASSO, and multivariate Cox regression analyses. The TNF family gene signature was related to age, pathological stages M and N, and could predict patient survival independently of clinical factors. Moreover, KEGG enrichment analysis suggested that the TNF family gene signature was mainly involved in the TGF-β signaling pathway, and the TNF family gene signature could affect the immunotherapy response. Finally, we confirmed that the mRNA expressions of CD27, TNF, TNFRSF12A, TNFRSF13C, and TNFRSF9 were upregulated in CC, while that of EDA was downregulated. The mRNA expressions of CD27, EDA, TNF, TNFRSF12A, TNFRSF13C, and TNFRSF9 might be influenced by gene methylation and copy number variation. Conclusion Our study is the first to demonstrate that CD27, EDA, TNF, TNFRSF12A, TNFRSF13C, and TNFRSF9 might be used as prognostic biomarkers of CC and are associated with the immunotherapy response of CC.

Abstract
BACKGROUND It has been demonstrated by studies globally that RNA binding proteins (RBPs) took part in the development of cervical cancer (CC). Few studies concentrated on the correlation between RBPs and overall survival of CC patients. We retrieved significant DEGs (differently expressed genes, RNA binding proteins) correlated to the process of cervical cancer development. METHODS Expressions level of genes in cervical cancer and normal tissue samples were obtained from GTEx and TCGA database. Differently expressed RNA binding proteins (DEGs) were retrieved by Wilcoxon sum-rank test. ClusterProfiler package worked in R software was used to perform GO and KEGG enrichment analyses. Univariate proportional hazard cox regression and multivariate proportional hazard cox regressions were applied to identify DEGs equipped with prognostic value and other clinical independent risk factors. ROC curve was drawn for comparing the survival predict feasibility of risk score with other risk factors in CC patients. Nomogram was drawn to exhibit the prediction model and validated by C-index and calibration curve. Correlations between differentially expressed RNA binding proteins (DEGs) and other clinical features were investigated by t test or Cruskal Wallis analysis. Correlation between Immune and DEGs in cervical cancer was investigated by ssGSEA. RESULTS 347 differentially expressed RBPs (DEGs) were retrieved from cervical cancer tissue and normal tissue samples. GO enrichment analysis showed that these DEGs involved in RNA splicing, catabolic process and metabolism. Cox regression model showed that there were ten DEGs significantly associated with overall survival of cervical cancer patients. WDR43 (HR = 0.423, P = 0.008), RBM38 (HR = 0.533, P < 0.001), RNASEH2A (HR = 0.474, P = 0.002) and HENMT1 (HR = 0.720, P = 0.071) played protective roles in survival among these ten genes. Stage (Stage IV vs Stage I HR = 3.434, P < 0.001) and risk score (HR = 1.214, P < 0.001) were sorted as independent prognostic risk factors based on multivariate cox regression. ROC curve validated that risk score was preferable to predict survival of CC patients than other risk factors. Additionally, we found some of these ten predictor DEGs were correlated significantly in statistic with tumor grade or stage, clinical T stage, clinical N stage, pathology or risk score (all P < 0.05). Part of immune cells and immune functions showed a lower activity in high risk group than low risk group which is stratified by median risk score. CONCLUSION Our discovery showed that many RNA binding proteins involved in the progress of cervical cancer, which could probably serve as prognostic biomarkers and accelerate the discovery of treatment targets for CC patients.

Abstract
Cervical cancer (CC) is a common gynaecological malignant tumour with a high mortality rate. Circular RNAs (circRNAs) play a critical role in tumour occurrence and development. This study aimed to investigate the function and molecular basis of hsa_circ_0009189 (circSAMD11) in CC development. RNA levels were determined by qRT-PCR, and protein expression was measured by western blot. Cell proliferation, migration, invasion and apoptosis were detected by Cell Counting Kit-8 (CCK-8), colony formation, Transwell and flow cytometry assays. The relationship between miR-503 and circSAMD11/SOX4 was validated via dual-luciferase reporter assay, RIP or RNA pull-down assay. Xenograft assay was conducted to test tumour growth in vivo. CircSAMD11 and SOX4 levels were elevated, while miR-503 level was reduced in CC tissues and cells. Knockdown of circSAMD11 suppressed CC cell proliferation, migration and invasion and accelerated apoptosis. CircSAMD11 was localised in cytoplasm and directly targeted miR-503. Also, circSAMD11 sponged miR-503 to modulate SOX4 expression. Additionally, circSAMD11 regulated CC progression via absorbing miR-503 or modulating SOX4. Besides, depletion of circSAMD11 hindered tumorigenesis in vivo. CircSAMD11 contributed to CC progression by regulating miR-503/SOX4 signalling and activating Wnt/β-catenin pathway, which provides a promising therapeutic target for cervical cancer.

Abstract
Background: Autophagy plays an important role in the development of cancer. However, the prognostic value of autophagy-related genes (ARGs) in cervical cancer (CC) is unclear. The purpose of this study is to construct a survival model for predicting the prognosis of CC patients based on ARG signature. Methods: ARGs were obtained from the Human Autophagy Database and Molecular Signatures Database. The expression profiles of ARGs and clinical data were downloaded from the TCGA database. Differential expression analysis of CC tissues and normal tissues was performed using R software to screen out ARGs with an aberrant expression. Univariate Cox, Lasso, and multivariate Cox regression analyses were used to construct a prognostic model which was validated by using the test set and the entire set. We also performed an independent prognostic analysis of risk score and some clinicopathological factors of CC. Finally, a clinical practical nomogram was established to predict individual survival probability. Results: Compared with normal tissues, there were 63 ARGs with an aberrant expression in CC tissues. A risk model based on 3 ARGs was finally obtained by Lasso and Cox regression analysis. Patients with high risk had significantly shorter overall survival (OS) than low-risk patients in both train set and validation set. The ROC curve validated its good performance in survival prediction, suggesting that this model has a certain extent sensitivity and specificity. Multivariate Cox analysis showed that the risk score was an independent prognostic factor. Finally, we mapped a nomogram to predict 1-, 3-, and 5-year survival for CC patients. The calibration curves indicated that the model was reliable. Conclusion: A risk prediction model based on CHMP4C, FOXO1, and RRAGB was successfully constructed, which could effectively predict the prognosis of CC patients. This model can provide a reference for CC patients to make precise treatment strategy.

Abstract
BACKGROUND Cervical cancer is a major health hazard to Indian women. Human papillomavirus (HPV) infection is an established risk factor for cervical carcinogenesis. However, understanding the cervical cancer biology beyond HPV infection is very crucial to predict aggressive behavior, prognosis, treatment response and survival. In the present study, we explored the role of vascular endothelial growth factor A (VEGFA) isoforms, VEGFC and VEGFD in cervical cancer progression and its association with HPV 16 and 18 infections. MATERIAL AND METHODS A total of 110 cervical cancer tissues and 50 normal cervical tissues were collected for the study. Reverse transcription-polymerase chain reaction was employed to analyze tissue VEGFA isoforms, VEGFC and VEGFD expression. RESULTS VEGF165 was significantly higher, whereas VEGFC and VEGFD were significantly lower in malignant cervical carcinoma tissues as compared to normal cervix tissues. Expression levels of VEGF121 and VEGFC were significantly associated with type of tumor growth while VEGF165 was significantly associated with lymph node metastasis. VEGF165 transcript levels were significantly higher in patients with squamous cell carcinoma (SCC) and developed recurrence. Most strikingly, higher VEGF165 expression was significantly associated with worst disease-free survival (DFS) specifically in patients with SCC. CONCLUSION Association of VEGF165 with lymph node metastasis, disease recurrence and worst DFS indicated that VEGF165 is an important prognostic factor in cervical carcinogenesis.

Abstract
Cervical cancer is an aggressive cutaneous malignancy, illuminating the molecular mechanisms of tumorigenesis and discovering novel therapeutic targets are urgently needed. KMT2A is a transcriptional co-activator regulating gene expression during early development and hematopoiesis, but the role of KMT2A in cervical cancer remains unknown. Here, we demonstrated that KMT2A regulated cervical cancer growth via targeting VADC1. Knockdown of KMT2A significantly suppressed cell proliferation and migration and induced apoptosis in cervical cancer cells, accompanying with activation of PARP/caspase pathway and inhibition of VADC1. Overexpression of VDAC1 reversed the KMT2A knockdown-mediated regulation of cell proliferation, migration and apoptosis. The in vivo results from a cervical cancer xenograft mouse model also validated that KMT2A knockdown suppressed tumor growth by inhibiting VDAC1, whereas KMT2A overexpression promoted cervical cancer growth. Moreover, analyses of Biewenga cervix database and clinical samples showed that both KMT2A and VDAC1 were upregulated in cervix squamous cell carcinoma compared with cervix uteri tissues, and their expression was negatively correlated with the differentiation grade of cervical cancer. Our results therefore indicated that the KMT2A/VDAC1 signaling axis may be a potential new mechanism of cervical carcinogenesis.

Abstract
Objective Cervical carcinoma (CC) is a serious threat to women’s health and few effective therapeutic methods have been discovered. The purpose of this study is to explore the underlying mechanism of miR-145-5p in CC. Methods Bioinformatics methods were employed to analyze the gene expression data of CC from TCGA database. qRT-PCR was used to detect the expression of miR-145-5p and KLF5 in CC cells, and Western blot was employed for the examination of KLF5 protein level. The targeted relationship between miR-145-5p and KLF5 was verified by a dual-luciferase reporter assay. Moreover, CCK-8, wound healing assay and transwell invasion assay were used to analyze the effects of miR-145-5p overexpression or KLF5 silencing on the proliferation, migration and invasion of CC cells. Results miR-145-5p was shown to be down-regulated in CC tissues and cells, while KLF5 was up-regulated. miR-145-5p could bind to the complementary sequence within the wild type KLF5 3ʹUTR rather than the mutant one. In addition, miR-145-5p could effectively down-regulate KLF5, in turn inhibiting the proliferation, migration and invasion of CC cells. Conclusion miR-145-5p regulates the proliferation, migration and invasion of CC cells by targeting KLF5.

Abstract
Background Cervical cancer is a major threat to female health worldwide. This study was performed to study the anticancer potential of sclareol and as a chemo-sensitizing agent against human cervical cancer cells along with evaluating its effects on apoptosis, cell cycle arrest, and MAPK/ERK signaling pathway. Material/Methods MTT assay was performed to check cell viability, morphological changes were observed through phase-contrast microscopy, DAPI (4′,6-diamidino-2-phenylindole) staining and TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labelling) assays were performed to evaluate apoptotic effects; MMP (matrix metalloproteinase) and cell cycle analysis were examined through flow cytometry. Western blotting analysis was performed to check the protein expressions of MAPK/ERK signaling pathway and apoptosis proteins. Results Results depicted that both sclareol and cisplatin induced cytotoxic effects individually but when used in combination, it led to much more pronounced cytotoxic effects indicating a synergistic effect of sclareol on cisplatin. Sclareol treatment led to significant decrease in the levels of p-MEK and p-ERK. Significant morphological changes (including chromatin condensation, nuclear fragmentation) in cervical cancer cells were seen after treatment. Western blot showed significant alterations including increase in BAX and decrease in BCL-2 levels. An increase in the S-phase cells, indicating cell cycle arrest at S-phase was seen along with modulating the expressions of CDK-1and Cdc25C, and increase in the levels of p-CDK-1, cyclin-B1, cyclin-A, and p-Cdc25C. Conclusions Sclareol not only induced cytotoxic effects but also enhanced chemosensitivity of human cervical cancer cells towards cisplatin and these effects are mediated via MAPK/ERK signaling pathway, stimulation of apoptosis and S-phase cell cycle arrest.

Abstract
The phosphorylation of EGFRThr654 is required for nuclear EGFR importing, and our previous study has shown that pEGFRThr654 is an independent prognostic factor for the low survival rate of patients with cervical squamous carcinoma. Now, we aim to examine the role of pEGFRThr654 in the activation of DNA-PK and radio resistance. Either CaSki or HeLa cells were exposed to a dose of 4 Gy with a 6 MV X-ray in the presence or absence of Cetuximab or Gefitinib, then EGFR, pEGFRThr654, DNA-PKcs and pDNA-PKThr2609 levels were determined using a western blot. DNA damage was quantified with γH2AX foci analysis and the response of CaSki and HeLa cells to irradiation was determined using a colony formation assay. In CaSki and HeLa cells, irradiation induced nuclear EGFR accumulation, and pEGFRThr654 and pDNA-PKThr2609 levels were both significantly increased. Cetuximab pre-treatment significantly reduced the expression of pEGFRThr654 and pDNA-PKThr2609 and enhanced the γH2AX foci per cell and sensitivity enhancement ratio in CaSki cells. Gefitinib pre-treatment had a similar but weaker effect. In HeLa cells, similar effects of Cetuximab and Gefitinib on pEGFRThr654 and pDNA-PKThr2609 were observed, and no significant difference was found. We found that Cetuximab had a better effect than Gefitinib on attenuating the radio resistance in cervical squamous carcinoma cells via inhibiting pEGFRThr654-mediated nuclear EGFR transport and related DNA-PKT2609-mediated DNA repair. However, in adenocarcinoma cells, both EGFR-targeted drugs had no remarkable effects on the radio sensitivity. Taken together, radiotherapy combined with Cetuximab may be a promising strategy to improve the therapeutic gain for cervical squamous carcinoma patients. The phosphorylation of EGFRThr654 is required for nuclear EGFR importing, and our previous study has shown that pEGFRThr654 is an independent prognostic factor for the low survival rate of patients with cervical squamous carcinoma.![]()

MicroRNA-367-3p overexpression represses the proliferation and invasion of cervical cancer cells through downregulation of SPAG5-mediated Wnt/β-catenin signalling. Clin Exp Pharmacol Physiol 2019; 47:687-695. [PMID: 31792998 DOI: 10.1111/1440-1681.13222] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 10/30/2019] [Accepted: 11/29/2019] [Indexed: 12/16/2022]
Abstract
MicroRNA-367-3p (miR-367-3p) has been previously reported as a cancer-related miRNA that is dysregulated in various cancer types and functions either as an oncogenic or as tumour suppressive miRNA. However, whether miR-367-3p is dysregulated in cervical cancer and, further, whether it contributes to the development and progression of the disease remains unknown. Here, our results demonstrated that miR-367-3p expression was markedly decreased in both cervical cancer tissues and cell lines compared with corresponding controls. In vitro experiments revealed that miR-367-3p overexpression repressed the proliferation and invasion of cervical cancer cells. Notably, sperm-associated antigen 5 (SPAG5) was identified as a target gene of miR-367-3p. Moreover, decreased expression of miR-367-3p was correlated with high expression of SPAG5 in cervical cancer tissue specimens. SPAG5 inhibition or miR-367-3p overexpression significantly downregulated Wnt/β-catenin signalling in cervical cancer cells. However, the antitumour effect mediated by miR-367-3p overexpression was partially reversed by SPAG5 overexpression. Overall, these findings demonstrate that miR-367-3p overexpression restricts the proliferation and invasion of cervical cancer cells through targeting SPAG5 to downregulate Wnt/β-catenin signalling, suggesting a mechanism for the tumour suppressive function of miR-367-3p in cervical cancer. Our study highlights the involvement of miR-367-3p/SPAG5/Wnt/β-catenin signalling axis in regulating the malignant progression of cervical cancer.

Abstract
BACKGROUND Cervical cancer is the most common gynecological malignancy, ranking first in female reproductive malignancies with more than 500000 new cases and 275000 deaths each year. Traditionally, open radical hysterectomy is considered the standard surgical procedure for the treatment of resectable cervical cancer. The latest guidelines from the National Comprehensive Cancer Network and the European Society of Gynecological Oncology suggest that open surgery and laparoscopic surgery (using traditional laparoscopic or robotic techniques) are the main surgical approaches for radical hysterectomy for patients with stage IA2-IIA cervical cancer. Robotic surgery has been increasingly used in abdominal surgery and has shown more beneficial effects.
AIM To analyse the perioperative conditions, complications, and short-term and long-term effects in patients undergoing robotic radical hysterectomy (RRH) and laparoscopic radical hysterectomy (LRH) to compare their clinical efficacy, safety, and feasibility.
METHODS The perioperative data of patients undergoing RRH and LRH were extracted and collected from the database of surgical treatments for cervical cancer for statistical analysis.
RESULTS Of the patients, 342 underwent LRH for cervical cancer, and 216 underwent RRH. The total complication rate was 9.65% (20 patients) in the RRH group and 17.59% (60 patients) in the LRH group. The complication rate was significantly lower in the RRH group than in the LRH group. There was no significant difference in the follow-up period (P = 0.658). The total recurrence rates were 15.7% and 12% in the RRH and LRH groups, respectively. The progression-free survival time was 28.91 ± 15.68 mo and 28.34 ± 15.13 mo in the RRH and LRH groups, respectively (P = 0.669). The overall survival (OS) rates were 92.13% and 94.45% in the RRH and LRH groups, respectively (P = 0.292). The OS time was 29.87 ± 15.92 mo and 29.41 ± 15.14 mo in the RRH and LRH groups, respectively (P = 0.732). The survival curves and the progression-free survival curves were not statistically significantly different between the two groups (P = 0.407 and 0.28, respectively).
CONCLUSION RRH is associated with significantly less operative time and blood loss than LRH. The two procedures have similar complication rates, OS, and progression-free survival time.

Abstract
Background/aims Radioresistance remains a significant obstacle in the therapy of cervical cancer, and the mechanism of it is still unclear. We aimed to investigate the role of specificity protein 1 (Sp1) in radioresistance of cervical cancer. Methods Sp1 was examined immunohistochemically on tissues from 36 human cervical cancer patients. We used RT-qPCR and Western blot to examine the expression of Sp1 in irradiated cervical cancer cell lines SiHa and HeLa. The role of Sp1 in radioresistance of cervical cancer cells was assessed by colony-formation assay and cell cycle analysis. Dual-luciferase reporter assay was performed to detect the downstream of Sp1. Results High Sp1 expression was positively correlated with advanced International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis, and lymphovascular space invasion (LVSI) of cervical cancer. The expression of Sp1 was dose-dependently increased in irradiated cervical cancer cell lines at both mRNA and protein levels. Colony-formation assay showed that alteration of Sp1 expression affected the survival of cervical cancer cells with radiotherapy (RT) treatment. Knockdown of Sp1 significantly strengthened the cellular response to radiation by inducing G2/M arrest in cervical cancer cells. Overexpression of Sp1 significantly decreased G2/M arrest in cervical cancer cells, which was related to upregulation of CDK1 expression. Dual-luciferase reporter assay showed the direct effect of Sp1 on the transcriptional activation of CDK1. Conclusion Sp1 may contribute to radioresistance through inhibiting G2/M phase arrest by targeting CDK1, and be considered as a potential therapeutic target to promote the effect of RT for patients with cervical cancer.

Abstract
Background It has been reported that miRNA-125b is associated with carcinogenesis and development of several different kinds of cancers. Nevertheless, there is no clarity regarding the significance and mechanism of action of miR-125b in clinical practice for cervical cancer (CC). Materials and methods In the current investigation, the expression of miR-125b in cervical clinical specimens and CC cell lines was analyzed via real-time quantitative PCR, and the relationship of miR-125b with the chromatin-associated protein high mobility group A (HMGA1) expression and clinicopathological parameters of CC patients was explored. Results The results indicated that miR-125b expression was remarkably upregulated in CC cell lines as well as in the tissues of humans. miR-125b overexpression was significantly related to a decrease in HMGA1 expression, progression-free survival, overall survival, and prognosis as well. Besides, knockdown of miR-125b inhibited proliferation and colony formation in SW756 and C4-1 cells, where the 3'-UTR of HMGA1 mRNA was directly targeted. Moreover, PI3K/Akt pathway was regulated by miR-125b through suppression of HMGA1. Conclusion These findings illustrated that a new regulatory role of HMGA1 is involved in the progression of CC. Our data demonstrated that miR-125b could play a critical role in the carcinogenesis and progression of CC, revealing that miR-125b might serve as a potential new target for treating CC.

Abstract
OBJECTIVE To assess the prognostic value of human papillomavirus (HPV) viral load in locally advanced cervical carcinoma treated with radical concurrent chemoradiotherapy. METHODS From January 2012 to October 2013, a total of 246 locally advanced cervical carcinoma patients were included in this retrospective study. HPV DNA status was tested by Hybrid Capture 2 assay. Tumor size was measured on T2WI. All the patients in the study received concurrent cisplatin-based chemoradiotherapy with intensity-modulated radiotherapy and three-dimensional brachytherapy. Survival rate was calculated by the Kaplan-Meier method, and a log-rank test was used to compare the survival. Multivariate analysis employed the Cox regression model. RESULTS The median follow-up time was 52 months. The median value of HPV DNA was 163.13 relative light unit/cut-off (RLU/CO) (range 1.65-2162.62 RLU/CO). The 5-year overall survival, distant metastasis-free survival of patients in the low HPV DNA group (HPV DNA ≤ 163.13 RLU/CO) and the high HPV DNA group (HPV DNA > 163.13 RLU/CO) were 46.3 % vs 58.5 % (p = 0.009) and 65.9 % vs 75.6% (p = 0.003), respectively. Multivariate analysis showed that the HPV DNA, tumor size, and International Federation of Gynecology and Obstetrics (FIGO) stage were independent prognostic factors for overall survival and distant metastasis-free survival. We choose the tumor size and HPV DNA as the risk stratification factors to build a new prediction marker which can better predict overall survival for locally advanced cervical cancer than can the FIGO stage. CONCLUSIONS HPV DNA may be a useful biomarker for locally advanced cervical cancer. Low HPV load predicts a worse survival. The new marker based on risk stratification by combining HPV DNA and tumor size is better associated with overall survival of locally advanced cervical cancer treated with concurrent chemoradiotherapy.

Abstract
Objective: To describe variation in incidence and mortality rates of cervical cancer (CC), between 4 Southern European countries that share similar cultural characteristics. Methods: Data on CC incidence and mortality reported in Portugal, Spain, Italy, and Greece for the year 2012 were obtained through the International Agency of Research on Cancer. Expected numbers of incident cases and deaths were obtained based on age-specific rates in European region. Standardized incidence rate (SIR) and standardized mortality rate (SMR) and respective 95% confidence interval (95% CI) were computed for each country by age group (15–39, 40–54, 55–64, and ≥65 years old). Results: The number of incident cases of and deaths due to CC observed in Greece, Italy, and Spain were significantly lower than expected, whichever the age group. In Portugal such pattern was, however, only found for incident cases among women aged up to 54 years. The number of incident cases observed in Portugal did not differ from that expected among women aged 55 to 64 (SIR = 90.8; 95% CI: 76.8–106.7) and aged 65 or more years (SIR = 110.0; 95% CI: 95.9–125.0). Also, the number of deaths observed in Portugal did not differ from that expected among women aged 15 to 39 (SMR = 70.0; 95% CI: 43.3–100.8), 40 to 54 (SMR = 93.6; 95% CI: 74.9–115.4), and 55 to 64 years (SMR = 93.6; 95% CI: 73.4–117.7) but was significantly higher than that expected among women aged 65 or more years (SMR = 126.7; 95% CI: 110.1–144.4). Conclusions: There is variability in CC incidence and mortality between 4 South European countries. To understand the reasons underlying such variability could improve approach to preventive care.

Comparative testing of HPV L1 protein monoclonal antibody panel for the detection of HPV in cervical exfoliated cells. J Virol Methods 2018; 257:33-41. [PMID: 29614248 DOI: 10.1016/j.jviromet.2018.03.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Revised: 03/26/2018] [Accepted: 03/31/2018] [Indexed: 12/13/2022]
Abstract
AIMS To determine the value of a monoclonal antibody panel against a C-terminal conserved sequence polypeptide of human papillomavirus (HPV) L1 (a major capsid protein) for the detection of HPV in cervical exfoliated cells, as well as the potential of this antibody panel to be developed into an assay kit for the clinical screening of cervical cancer. METHODS Cervical exfoliated cells were collected at a gynecology clinic. One part of each sample was sent to the Department of Pathology for HPV genotyping, and the other part was sent to the Department of Pathology for cytologic testing and then to the laboratory for immunological histological chemistry (IHC) assay in which an HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was used to detect HPV L1. RESULTS Cervical cell samples were collected from 514 patients at the gynecology clinic; of these, 339 samples were sent for HPV genotyping, and 220 were HPV positive (64.90%, 220/339). Moreover, the duplicate samples from these 339 patients were sent for IHC assay, and 229 samples were positive (67.55%, 229/339). The IHC result was concordant with that obtained by HPV genotyping (Kappa = 0.743, p < 0.001). CONCLUSION This study showed that use of the HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was of great value for the detection of HPV in cervical cells; the resulting detection rate was comparable to that obtained using the commercial HPV genotyping kit that is currently in use in clinical practice.

Abstract
OBJECTIVE This study aimed to evaluate the clinical efficacy of different target volumes in pelvic radiotherapy in postoperative treatment of cervical cancer based on the Sedlis criteria. METHODS Patients who admitted to our department for post-operative radiotherapy of cervical cancer from December 2001 to December 2011 and met the Sedlis criteria were retrospectively analysed. The incidences of acute and late radiation injuries, and overall, disease-free and tumour-specific survival with reduced-volume pelvic and whole-pelvis radiotherapy were evaluated and compared. RESULTS A total of 371 patients were included in the study, including 239 receiving whole-pelvis radiotherapy and 132 receiving reduced-volume pelvic radiotherapy. The volume of contours for mean PTV volumes, bilateral femoral heads and small intestine volumes in reduced-volume pelvic radiotherapy were lower than whole-pelvis radiotherapy; the results were similar to the V10, V20, V30, V40 and V45 for pelvic bone marrow and small intestine dose volume (both p < 0.05). The acute radiation injury observed in the two groups was mainly haematologic toxicity and upper and lower gastrointestinal symptoms. The incidences of acute radiation injury, and late radiation injury of gastrointestinal and urinary tracts were both significantly lower with reduced-volume pelvic radiotherapy than with whole-pelvis radiotherapy (both p < 0.05). Moreover, there was no significant difference in the incidence of lower extremity oedema, or 2-year or 5-year overall, disease-free or tumour-specific survival between groups (all p > 0.05). CONCLUSION Reduced-volume pelvic radiotherapy could relieve acute and late radiation injuries, especially myelosuppression, and did not affect long-term survival. Advanced in knowledge: Our study shows that reduced-volume base on National Comprehensive Cancer Network 2016 is more fit for cervical cancer than others.

Lancet 2017; 390:1654-1663. [PMID: 28756902 PMCID: PMC5714293 DOI: 10.1016/s0140-6736(17)31607-0] [Citation(s) in RCA: 362] [Impact Index Per Article: 51.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2017] [Revised: 05/15/2017] [Accepted: 05/18/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND On Aug 14, 2014, the US Food and Drug Administration approved the antiangiogenesis drug bevacizumab for women with advanced cervical cancer on the basis of improved overall survival (OS) after the second interim analysis (in 2012) of 271 deaths in the Gynecologic Oncology Group (GOG) 240 trial. In this study, we report the prespecified final analysis of the primary objectives, OS and adverse events. METHODS In this randomised, controlled, open-label, phase 3 trial, we recruited patients with metastatic, persistent, or recurrent cervical carcinoma from 81 centres in the USA, Canada, and Spain. Inclusion criteria included a GOG performance status score of 0 or 1; adequate renal, hepatic, and bone marrow function; adequately anticoagulated thromboembolism; a urine protein to creatinine ratio of less than 1; and measurable disease. Patients who had received chemotherapy for recurrence and those with non-healing wounds or active bleeding conditions were ineligible. We randomly allocated patients 1:1:1:1 (blocking used; block size of four) to intravenous chemotherapy of either cisplatin (50 mg/m2 on day 1 or 2) plus paclitaxel (135 mg/m2 or 175 mg/m2 on day 1) or topotecan (0·75 mg/m2 on days 1-3) plus paclitaxel (175 mg/m2 on day 1) with or without intravenous bevacizumab (15 mg/kg on day 1) in 21 day cycles until disease progression, unacceptable toxic effects, voluntary withdrawal by the patient, or complete response. We stratified randomisation by GOG performance status (0 vs 1), previous radiosensitising platinum-based chemotherapy, and disease status (recurrent or persistent vs metastatic). We gave treatment open label. Primary outcomes were OS (analysed in the intention-to-treat population) and adverse events (analysed in all patients who received treatment and submitted adverse event information), assessed at the second interim and final analysis by the masked Data and Safety Monitoring Board. The cutoff for final analysis was 450 patients with 346 deaths. This trial is registered with ClinicalTrials.gov, number NCT00803062. FINDINGS Between April 6, 2009, and Jan 3, 2012, we enrolled 452 patients (225 [50%] in the two chemotherapy-alone groups and 227 [50%] in the two chemotherapy plus bevacizumab groups). By March 7, 2014, 348 deaths had occurred, meeting the prespecified cutoff for final analysis. The chemotherapy plus bevacizumab groups continued to show significant improvement in OS compared with the chemotherapy-alone groups: 16·8 months in the chemotherapy plus bevacizumab groups versus 13·3 months in the chemotherapy-alone groups (hazard ratio 0·77 [95% CI 0·62-0·95]; p=0·007). Final OS among patients not receiving previous pelvic radiotherapy was 24·5 months versus 16·8 months (0·64 [0·37-1·10]; p=0·11). Postprogression OS was not significantly different between the chemotherapy plus bevacizumab groups (8·4 months) and chemotherapy-alone groups (7·1 months; 0·83 [0·66-1·05]; p=0·06). Fistula (any grade) occurred in 32 (15%) of 220 patients in the chemotherapy plus bevacizumab groups (all previously irradiated) versus three (1%) of 220 in the chemotherapy-alone groups (all previously irradiated). Grade 3 fistula developed in 13 (6%) versus one (<1%). No fistulas resulted in surgical emergencies, sepsis, or death. INTERPRETATION The benefit conferred by incorporation of bevacizumab is sustained with extended follow-up as evidenced by the overall survival curves remaining separated. After progression while receiving bevacizumab, we did not observe a negative rebound effect (ie, shorter survival after bevacizumab is stopped than after chemotherapy alone is stopped). These findings represent proof-of-concept of the efficacy and tolerability of antiangiogenesis therapy in advanced cervical cancer. FUNDING National Cancer Institute.

Abstract
Background Invasive cervical cancer (ICC) is the third most common malignant neoplasm affecting Brazilian women. Little is known about the impact of specific HPV genotypes in the prognosis of ICC. We hypothesized that HPV genotype would impact ICC clinical presentation and survival. Methods Women diagnosed with ICC at the Instituto do Câncer do Estado de São Paulo (ICESP) between May 2008 and June 2012 were included in the study and were followed until December 2015. HPV genotype was detected from formalin-fixed paraffin-embedded (FFPE) tumor tissue samples using Onclarity™ system (BD Viper™ LT automated system). Results 292 patients aged 50±14 years were analyzed. HPVDNA was detected in 84% of patients. The HPV genotypes studied were: HPV16 (64%), HPV18 (10%), HPV33-58 (7%), HPV45 (5%), HPV31 (4%) and other high-risk HPV genotypes (11%). HPV genotypes showed different distributions regarding histological type and clinical stage. Patients were followed for 35±21 months. The overall survival at 5 years after diagnosis of cervical cancer was 54%. Age, clinical staging, histological type and multiple HPV genotypes infection detected in the same tumor specimen were associated with poorer overall survival on multivariate Cox proportional hazard analysis (p<0.05). No specific HPV genotype affected survival. Conclusion Multiple HPV genotype infection was associated with poorer ICC survival in our study, compared with single genotype infection. HPV genotyping from FFPE tumor tissue using an automated assay such as the Onclarity BD™ assay provides a simpler alternative for routine clinical use. Impact This is the largest study employing an automated HPV genotyping assay using FFPE of ICC. Multiple HPV genotype infection adversely influenced survival.

TGF-β1-induced CK17 enhances cancer stem cell-like properties rather than EMT in promoting cervical cancer metastasis via the ERK1/2-MZF1 signaling pathway. FEBS J 2017; 284:3000-3017.

Abstract
Tumor metastasis remains a major obstacle for improving overall cancer survival in cervical cancer (CC), which may be due to the existence of tumor microenvironment-related cancer stem cells (CSCs) and epithelial-mesenchymal transition (EMT). The mechanism underlying these processes needs to be further elucidated. Here, we report that TGF-β1, one of the key microenvironmental stimuli, can enhance CSC characteristics, facilitate the EMT, and induce CK17. Silencing CK17 expression attenuated CSC-like properties without affecting the EMT markers induced by TGF-β1, whereas forced overexpression of CK17 promoted lymphatic metastasis in vivo even without EMT inducement. Inhibitors of ERK1/2 signaling drastically decreased the induction of CK17 mediated by TGF-β1. By combined computational and experimental approaches, we identified and validated that MZF1 was a key transcription factor binding to the promoter of CK17. Taken together, these results demonstrate that CK17 induced by the TGF-β1-ERK1/2-MZF1 signaling pathway facilitates metastasis by promoting the acquisition of CSC properties rather than by inducing the EMT process in CC, suggesting that this CK17-related signaling pathway might be a suitable target for the development of therapy for CC metastasis.

Abstract
Cervical cancer is the second most common type of cancer in women accounting for 12% of all human cancers in the world. Mounting evidence demonstrates that microRNAs play important roles in the carcinogenesis and progression of cervical cancer. The aim of this study was to investigate the expression, roles and molecular mechanism of microRNA-362 (miR-362) in cervical cancer. According to the results, we found that expression level of miR-362 was significantly reduced in cervical cancer tissues and cell lines. Low miR-362 expression was correlated with FIGO stage, lymph node metastasis and vascular invasion in cervical cancer. Functional assays showed that restoration of miR-362 repressed cell proliferation, migration and invasion in cervical cancer. We also provided direct evidence that sineoculis homeobox homolog 1 (SIX1) was a direct target of miR-362 in cervical cancer, which was confirmed by bioinformatics analysis, luciferase reporter assay, qRT-PCR and western blot analysis. SIX1 was upregulated in cervical cancer and inversely correlated with miR‑362 expression in cervical cancer. In addition, SIX1 knockdown could simulate the roles of miR-362 overexpression on cell proliferation, migration and invasion of cervical cancer. Moreover, rescue experiments indicated that restoration of SIX1 was sufficient to abolish proliferation, migration and invasion induced by miR-362 overexpression in cervical cancer cells. The newly identified miR-362/SIX1 pathway provides insight into cervical cancer progression, and may represent a novel therapeutic target.

Abstract
OBJECTIVE The aim of this study was to compare the efficacy and toxicity of different concurrent chemoradiotherapy (CCRT) regimens in the treatment of advanced cervical cancer (CC) by adopting a network meta-analysis. METHODS We searched PubMed and Cochrane Library from the inception of these databases to September 2016, and all cohort studies (CSs) related to different CCRT regimens in the treatment of CC were included. A network analysis was adopted to compare the combination of direct and indirect evidence, to analyze the odds ratio (OR), and to draw a surface under the cumulative ranking curve of the efficacy and toxicity of different CCRT regimens for CC. Cluster analyses were used to group each category based on similar treatment regimens. RESULTS Nineteen CSs were enrolled in this network meta-analysis, including 12 CCRT regimens (radiotherapy [RT], CCRT [cisplatin], CCRT [vinorelbine], CCRT [paclitaxel], CCRT [hydroxyurea], CCRT [cisplatin + FU], CCRT [cisplatin + gemcitabine], CCRT [cisplatin + docetaxel], CCRT [cisplatin + paclitaxel], CCRT [cisplatin + amifostine], CCRT [cisplatin + FU + hydroxyurea], and CCRT [cisplatin + vincristine + bleomycin]). The results of the network meta-analysis showed that regarding efficacy, the overall response rate of CCRT (cisplatin + docetaxel) was higher than RT, and the 5-year overall survival (OS) rate of CCRT (cisplatin + FU + hydroxyurea) was relatively higher than CCRT (hydroxyurea). As for toxicity, CCRT (cisplatin) had a lower incidence of leukopenia than CCRT (hydroxyurea), CCRT (cisplatin + FU) and CCRT (cisplatin + paclitaxel), and the incidences of diarrhea and vomiting in CCRT (cisplatin) were lower than those in CCRT (cisplatin + gemcitabine). Additionally, the cluster analysis showed that CCRT (cisplatin) had relatively lower incidences of both hematotoxicity and gastrointestinal toxicity, and CCRT (paclitaxel) had lower gastrointestinal toxicity than other regimens. CONCLUSION Our study demonstrated that CCRT (cisplatin + docetaxel) might be the best choice of CCRT regimens in the treatment of CC, and the 5-year OS rate of CCRT (cisplatin + FU + hydroxyurea) might be the highest among these different regimens. CCRT (cisplatin) might have the lowest toxicity among all the CCRT regimens.

Abstract
Aberrant activation of the canonical Wnt pathway plays a significant role in cervical cancer (CC). However, limited data show the correlation between the cancer clinicopathological characteristics and the key molecules such as β-catenin and Wnt inhibitory factor 1 (WIF1). In this study, β-catenin and WIF1 expression were analyzed by immunohistochemistry for 196 patients with CC, 39 with cervical intraepithelial neoplasia (CIN), and 41 with normal cervical epithelium (NCE). Significant overexpression of β-catenin was detected in CC (67.9%) when compared to CIN (43.6%) or NCE (34.1%), p < 0.01, while low WIF1 expression was detected in CC (24.0%) when compared to CIN (59.0%) or NCE (58.5%), p < 0.001. Negative correlation was shown between β-catenin and WIF1 expression (r = −0.637, p < 0.001). In addition, multivariate analysis revealed that both lymph node metastasis and β-catenin expression were the independent prognostic factors not only for disease-free survival (HR = 5.029, p < 0.001; HR = 2.588, p = 0.035, resp.), but also for overall survival (HR = 5.058, p < 0.001; HR = 2.873, p = 0.031, resp.). Our findings indicate that, besides lymph node metastasis, β-catenin expression may also be a poor prognostic factor for CC while WIF1 could be a potential drug target for treatment of advanced CC.

Abstract
OBJECTIVE This study aims to assess treatment compliance among women undergoing definitive chemoradiation with weekly cisplatin for cervical cancer within a safety net health system and to quantify the impact of chemotherapy compliance on outcomes. MATERIALS AND METHODS All women who were treated for International Federation of Gynecology and Obstetrics stage IB2 to stage IVA cervical cancer between April 2008 and May 2014 were identified. Treatment delays were attributed to toxicity, comorbid conditions, or system issues, or categorized as patient-initiated. Disease-free survival and overall survival of women who received fewer than 6 versus 6 or more doses of weekly cisplatin 40 mg/m were compared using Kaplan-Meier analyses. RESULTS One hundred nineteen women (mean [SD] age, 48.5 [11.8] years) were identified. Most women (n = 112; 94.1%) completed definitive radiotherapy, requiring a mean (SD) of 56.5 (20.1) days. Sixty-four women (57.1%) completed definitive radiotherapy in 56 days or less. Only 44 women (36.4%) received 6 or more cycles of cisplatin. Of 122 delayed cycles, reasons for delay were as follows: grade 2 or higher toxicity (n = 70; 57.4%), medical comorbidity (n = 12; 9.8%), system issues (n = 9; 7.4%), and patient-initiated (n = 14; 11.5%). Multiple issues complicated treatment for 3 doses (2.5%). Reasons for delay were not documented in 14 doses (11.5%). Among patients who received 6 or more cycles, disease-free survival improved by 17.4 months (mean [SD], 61.1 [3.7] vs 43.7 [4.3] months, P = 0.002) and overall survival improved by 8.6 months (mean [SD], 68.7 [2.3] vs 60.1 [3.7] months, P = 0.011). CONCLUSIONS Higher rates of toxicity and psychosocial barriers to chemotherapy compliance adversely impact survival among women who seek care in low-resource settings. In our population, administration of all 6 cycles of cisplatin was necessary for optimal survival benefit. Future efforts to improve cervical cancer outcomes should address preventable reasons for treatment delays among underinsured or uninsured individuals.

Abstract
Cervical cancer is the most common gynecological cancer in Brazil. Among women, it is the second most frequent, second only to breast cancer. It is the fourth leading cause of cancer death in the country, with estimated 15,590 new cases (2014) and 5,430 deaths (2013). In order to update information to improve outcomes, reduce morbidity and optimize the treatment of this cancer, this article will address the advancement of knowledge on cervical cancer. The topics covered include the role of surgery in different stages, treatment of locally advanced carcinomas, fertility preservation, the role of the sentinel lymph node technique, indications and techniques of radiotherapy and chemotherapy, and some special situations.

Abstract
Virtually all cases of invasive cervical cancer are associated with infection by high-risk strains of human papilloma virus. Effective primary and secondary prevention programs, as well as effective treatment for early-stage invasive cancer have dramatically reduced the burden of cervical cancer in high-income countries; 85% of the mortality from cervical cancer now occurs in low- and middle-income countries. This article provides an overview of challenges to cervical cancer care in sub-Saharan Africa (SSA) and identifies areas for programmatic development to meet the global development goal to reduce cancer-related mortality. Advanced stage at presentation and gaps in prevention, screening, diagnostic, and treatment capacities contribute to reduced cervical cancer survival. Cost-effective cervical cancer screening strategies implemented in low resource settings can reduce cervical cancer mortality. Patient- and system-based barriers need to be addressed as part of any cervical cancer control program. Limited human capacity and infrastructure in SSA are major barriers to comprehensive cervical cancer care. Management of early-stage, locally advanced or metastatic cervical cancer involves multispecialty care, including gynecology oncology, medical oncology, radiology, pathology, radiation oncology, and palliative care. Investment in cervical cancer care programs in low- and middle-income countries will need to include effective recruitment programs to engage women in the community to access cancer screening and diagnosis services. Though cervical cancer is a preventable and treatable cancer, the challenges to cervical control in SSA are great and will require a broadly integrated and sustained effort by multiple stakeholders before meaningful progress can be achieved.

Abstract
Cervical cancer is one of the most common gynecological cancers worldwide. Aberrant expression of E3 ubiquitin ligase isolated by differential display (EDD) has been detected in various types of tumor and has been demonstrated to have an important role in carcinogenesis, tumor growth and drug resistance. However, the role of EDD in cervical cancer and its underlying molecular mechanisms remains unknown. The present study aimed to investigate the role of EDD in the tumorigenicity of cervical cancer. EDD expression levels were measured using reverse transcription-quantitative polymerase chain reaction and western blotting in SiHa, HeLa, CaSki, c-41 and c-33A cervical cancer cell lines and cervical cancer tissue specimens. A functional study was performed using cell proliferation, colony formation, cell apoptosis assays in vitro and tumor growth assays in vivo with EDD either overexpressed or silenced. In the present study, EDD expression levels were significantly upregulated in cervical cancer cell lines and tissue samples. EDD knockdown significantly inhibited colony formation, cell proliferation and tumor growth and accelerated cell apoptosis in the cervical cancer cell lines and tissue samples. Furthermore, microRNA (miR)-143 expression levels were low in cervical cancer tissue samples and were negatively correlated with EDD expression. miR-143 silencing eliminated the effect of EDD on cell proliferation, colony formation and cell apoptosis in the cervical cancer cells, which suggested that miR-143 is critical for EDD-mediated regulation of cervical cancer cell growth. The results of the present study indicated that EDD may promote cervical cancer growth in vivo and in vitro by targeting miR-143. In conclusion, EDD may have an oncogenic role in cervical cancer and may serve as a potential therapeutic target for the treatment of patients with cervical cancer.

Abstract
Despite the declining incidence of cervical cancer as a result of the introduction of screening programs, globally it remains a leading cause of cancer-related death in women. Outcomes for patients who are diagnosed with anything but early-stage disease remain poor. Here we examine emerging strategies to improve the treatment of locally advanced disease. We discuss emerging biologic data, which are informing our investigation of new therapeutic interventions in persistent, recurrent, and metastatic cervical cancer. We recognize the importance of interventions to improve quality of life and to prevent long-term sequelae in women undergoing treatment. Finally, and perhaps most importantly, we recognize the need for global collaboration and advocacy to improve the outcome for all women at risk of and diagnosed with this disease.

Abstract
BACKGROUND Systemic therapy options are needed for women with recurrent, metastatic, or persistent cervical cancer. This systematic review and clinical practice guideline were developed to address that need, and to update a 2007 guideline from Cancer Care Ontario's Program in Evidence-Based Care. METHODS The literature between 2006 and April 2014 in the medline and embase databases, the Cochrane Database of Systematic Reviews (Issue 4, 2014), the Cochrane Central Register of Controlled Trials (Issue 3, 2014), relevant guideline databases, and conference proceedings of the American Society of Clinical Oncology (2007-2013) was searched. A working group developed draft guidelines and incorporated comments and feedback from internal and external reviewers. RESULTS Four phase iii randomized controlled trials met the inclusion criteria for the review and provided the basis for draft recommendations. Feedback was obtained from Ontario practitioners and others abroad, which led to modifications to the draft recommendations. Three key recommendations were developed. CONCLUSIONS The working group concluded that all patients should be offered the opportunity to participate in appropriate randomized clinical trials. Cisplatin-paclitaxel, cisplatin-vinorelbine, cisplatin-gemcitabine, and cisplatin-topotecan are recommended combinations for this patient population. The substitution of carboplatin for cisplatin in the foregoing combinations can also be recommended because carboplatin is associated with fewer adverse effects and greater ease of administration. Selection of combination chemotherapy will depend on the toxicity profile, patient preference, and other factors. Finally, bevacizumab in combination with cisplatin-paclitaxel or carboplatin-paclitaxel is recommended for a specific subset of the target population as outlined in Gynecologic Oncology Group study 0240.
