Abstract
Background: The comprehensive treatment mode of combining concurrent chemoradiotherapy (CCRT) with adjuvant chemotherapy (AC) is a commonly used mainstream model in the clinical practice of locally advanced cervical cancer (LACC). However, the necessity for AC after CCRT lacks sufficient evidence-based medical support. This study constructs a predictive model for the survival time dependence of CCRT ± AC for LACC based on the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging with internal validation, the prognosis was assessed with intensity-modulated radiotherapy (IMRT) and concurrent cisplatin, and provides guidance for future stratified treatment. Materials and Methods: The retrospective analysis included 482 patients with LACC who CCRT from January 2016 to January 2023. Patients who used the 2009 FIGO staging were all standardized for the 2018 FIGO staging. The 482 patients with LACC were divided into a training set (n = 290) and a validation set (n = 192) at a ratio of 6:4. COX multivariate regression model and LASSO regression were used to screen for independent prognostic factors affecting progression-free survival (PFS) and overall survival (OS), and a nomogram clinical prediction model was constructed based on these factors. Evaluate the effectiveness of the model through the receiver operating characteristic curve, calibration curve, decision curve, risk heat map, and survival curves for risk stratification. Results: The PFS and OS independent prognostic risk factors affecting the 2018 FIGO staging of LACC during CCRT were validated to be similar to the 2009 FIGO staging prediction model reported in previous literature. In the training cohort, area under the curve (AUC) values at 1, 3, and 5 years were 0.941, 0.882, and 0.885 for PFS, and 0.946, 0.946, and 0.969 for OS, respectively. When applied to a test cohort, the model also showed accurate prediction result (AUC at 1, 3, and 5 years were 0.869, 0.891, and 0.899 for PFS, and 0.891, 0.941 and 0.878 for OS, respectively). Subgroup analysis suggests that patients with LACC, adenocarcinoma, stage IVA, pelvic lymph node metastasis, pretreatment hemoglobin ≤100 g/l and residual tumor diameter >2 cm, who received CCRT in the 2018 FIGO stage, may benefit more from adjuvant chemtherapy. Conclusions: Based on the 2018 FIGO staging, a nomogram prediction model for PFS and OS in patients with LACC undergoing CCRT was developed. The model, established by combining weighted clinical and pathological factors, can provide more personalized treatment predictions in clinical practice. For patients with high-risk factors such as residual tumor diameter > 2 cm after CCRT for LACC, AC may bring benefits.

Abstract
Cervical cancer (CC) is the second most common type of cancer in women, and presents a serious threat to public health. We aimed to investigate the regulatory impacts of CDGSH iron-sulfur domain-containing protein 2 (CISD2) in CC and to discuss its relationship with E2F transcription factor 7 (E2F7). With the employment of real-time reverse transcriptase-polymerase chain reaction (RT-qPCR) and western blot, the expression of CISD2 and E2F7 in SiHa cells before or after transfection was estimated. Cell counting kit-8 (CCK-8) assay, Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) assay, wound healing and transwell were used to detect the proliferation, apoptosis, migration and invasion of SiHa cells. The activity of CISD2 was detected using luciferase report assay and chromatin immunoprecipitation (ChIP) assay was used to confirm the binding of E2F7 and CISD2 promoter. The contents of proliferation- and apoptosis-related proteins were detected using western blot. Results revealed that CISD2 expression was greatly enhanced in CC cell lines. CISD2 depletion inhibited the proliferation, migration and invasion of SiHa cells but promoted the cell apoptosis. It was also found that E2F7 was remarkably elevated in SiHa cells. According to JASPAR database, the binding sites of E2F7 and CISD2 were predicted and ChIP confirmed the binding of E2F7 and CISD2 promoter. Results obtained from luciferase report assay indicated that E2F7 overexpression increased the activity of CISD2 promoter region. Furthermore, further functional experiments demonstrated that the impacts of E2F7 interference on the proliferation, migration, invasion and apoptosis of SiHa cells were reversed by CISD2 overexpression. In summary, CISD2 silence could alleviate the malignant progression of CC and could be transcribed by E2F7.

Abstract
One of the major causes of death on the globe is cancer. The fourth most frequent malignancy in women worldwide is cervical cancer. Several cancer patients are remaining incurable due to the emergence of medication resistance, despite notable advances in cancer research over the previous few decades. The importance of natural sources as possible therapeutic candidates may be significant. Anthraquinones are one of the many chemical families of natural products, and they stand out for their wide range of structural variations, notable biological activity, and low toxicity. A natural substance called emodin, an anthraquinone derivative, is present in the roots and rhizomes of several plants. This substance has demonstrated antineoplastic, anti-inflammatory, antiangiogenic, and antiproliferative properties. It is also capable of preventing cancer spread and can reverse cancer cells' multidrug resistance. Emodin, a broad-spectrum inhibitor of cancer cells, have anticancer properties in many different types of biological pathways. These molecular mechanisms in cancer cells include the suppression of cell growth and proliferation, deterioration of the cell cycle arrest, the start of apoptosis, antimetastasis, and antiangiogenic impact. Therefore, the aim of the present review summarised the antiproliferative and anticarcinogenic qualities of cervical cancer of emodin.

Abstract
The participation of circular RNAs (circRNAs) in carcinogenesis is widely established. Numerous circRNAs with aberrant expression in cervical cancer (CC) are identified by RNA sequencing, whereas the function of these circRNAs remains unclear. We thus aimed to unveil the effects and mechanisms of circ_0042986 in CC. Circ_0042986 with aberrant downregulation in CC was obtained from GSE10286 dataset. qPCR and western blotting were employed for the detection of circ_0042986, miR-582-3p, and paternally expressed 3 (PEG3) expressions. EdU assay, colony formation assay, wound healing assay, transwell assay, tube formation assay, and flow cytometry assay were applied for functional analyses. The potential binding site was ensured by dual-luciferase reporter analysis, and their binding relationship was verified by pull-down assay. The transplanted tumor models were constructed for in vivo function verification of circ_0042986. Our findings exposed that the downregulation of circ_0042986 was verified in clinical CC samples. Circ_0042986 overexpression largely attenuated CC cell growth, invasiveness, angiogenesis, and survival. MiR-582-3p was targeted by circ_0042986, and the inhibitory roles of circ_0042986 presence were partly abolished by miR-582-3p enrichment. MiR-582-3p combined with PEG3, and circ_0042986 increased PEG3 expression via decoying miR-582-3p. The interaction between miR-582-3p and PEG3 on CC cell functions was confirmed, evidenced by the reversal effects of PEG3 knockdown on miR-582-3p deficiency-inhibited cancer cell malignant behaviors. Circ_0042986 overexpression also limited tumorigenesis of CC in animal models. In summary, circ_0042986 overexpression decoyed miR-582-3p to increase PEG3 expression, thereby blocking the malignant progression of CC.

Abstract
Human papillomavirus (HPV) infections are the primary cause of almost all cervical cancers, anal cancers, and a variable proportion of other anogenital tumors, as well as head and neck cancers. Circulating HPV DNA (cHPV-DNA) is emerging as a biomarker with extensive potential in the management of HPV-driven malignancies. There has been a rapid advancement in the development of techniques for analyzing cHPV-DNA for the detection, characterization, and monitoring of HPV-associated cancers. As clinical evidence accumulates, it is becoming evident that cHPV-DNA can be used as a diagnostic tool. By conducting clinical trials assessing the clinical utility of cHPV-DNA, the full potential of cHPV-DNA for the screening, diagnosis, and treatment of HPV-related malignancies can be corroborated. In this review, we examine the current landscape of applications for cHPV-DNA liquid biopsies throughout the cancer care continuum, highlighting future opportunities for research and integration into clinical practice.

Abstract
OBJECTIVE We aimed to analyze the diagnostic test accuracy of positron emission tomography and a magnetic resonance imaging scan (PET-MRI) fusion in evaluating tumor response after radiochemotherapy in patients with locally advanced cervical cancer. METHODS Patients treated at two institutes between January 2008 and December 2016 were studied retrospectively. Re-evaluation by positron emission tomography (PET) and magnetic resonance imaging (MRI) was performed in a non-concurrent way 4-8 weeks after treatment. A nuclear medicine doctor and a radiologist (subsequently referred as "radiologists"), both experts in gynecological oncology, re-examined the post-treatment MRI and positron emission tomography-computed tomography (PET-CT) separately, and then performed a fusion of these examinations. In this study we describe this "a posteriori fusion methodology", with two levels, enabling limitation of anatomical shifts. The gold standard was anatomical pathology analysis of the surgical specimen, since all patients underwent surgery following this radiological re-evaluation. The radiologists' degree of certainty in their diagnoses, and the impact of fusion on their diagnostic confidence were assessed by the radiologists, using two Likert judgment scales. They also adjudicated on possible changes of interpretation after the fusion. RESULTS Thirty-one patients were included. The PET-MRI fusion has a sensitivity of 79% and a specificity of 90%. The positive predictive value (PPV) was 94%, and the negative predictive value (NPV) was 69%. In 45% of cases (n=13), radiologists reported an improvement in their degree of certainty in their diagnosis using a Likert judgment scale, due to inspecting the PET and MRI fused. A change in interpretation of tumor response was observed using a Likert judgment scale in 31% of cases. CONCLUSION PET-MRI fusion improves the radiologist's own diagnostic confidence in assessing response to concurrent radiochemotherapy in locally advanced cervical cancer. More studies using a latest generation hybrid system will be necessary to further compare to MRI and PET-CT.

High DHCR7 Expression Predicts Poor Prognosis for Cervical Cancer. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:8383885.

Abstract
DHCR7 is a rate-limiting enzyme in cholesterol synthesis. The expression pattern and prognostic value of DHCR7 in cervical cancer are unknown. We investigated the relationship between DHCR7 expression and clinicopathological features of cervical cancer patients. The dataset was acquired from TCGA database. The Wilcoxon rank sum test was used to explore DHCR7 expression level in cervical cancer. The Kruskal-Wallis test and the logistic regression were performed to estimate the association between the DHCR7 and clinical features. The Kaplan-Meier and Cox regression analyses were used to evaluate factors that affect cervical cancer prognosis. GSEA was used to screen the DHCR7-related pathways. We found that DHCR7 was increased in cervical cancer samples and increased DHCR7 was correlated with advanced T stage, lymph node invasion, and clinical stage (P < 0.05). Patients with elevated DHCR7 levels had poorer overall survival (P = 0.021), progression-free interval (P = 0.002), and disease-specific survival (P = 0.005). Cox analysis revealed that DHCR7 was an independent prognostic factor in cervical cancer (P = 0.005). WNT activated receptor activity, G2/M checkpoint, mTORC1 signaling, KRAS signaling, regulation of cholesterol biosynthetic, FGF signaling, T-cell receptor signaling, JAK/STAT signaling cascade T cell activation, and macrophage migration were enriched in high DHCR7 phenotype. Our data also showed that DHCR7 moderately correlates with T-cell infiltration, including CD8+ T-cells. Conclusion. Increased DHCR7 expression is associated with poor survival in cervical cancer.

Abstract
Hypoxia regulates fibroblast function by changing intracellular signaling and secretion factors, that influence the states of nearby cells. In this work, we investigated how medium (CM) from human adult dermal fibroblasts (HDFs) cultured in normoxic and hypoxic conditions affected cervical cancer (HeLa) cells. The HeLa cells showed decreased cell viability, increased apoptosis, and cell cycle arrest in response to CM from hypoxic-cultured HDFs (H-CM) compared with CM from normoxic-cultured HDFs (N-CM). Among the proteins up-regulated (>2-fold) in H-CM compared with N-CM, lymphotoxin-beta receptor (LTBR) decreased the viability of HeLa cells. Among the intracellular proteins down-regulated (>2-fold) in HeLa cells treated with H-CM compared with N-CM, the most enriched biological process GO term and KEGG pathway were protein deubiquitination and hsa05166:HTLV-I infection, respectively. In the protein−protein interaction network of intracellular proteins with altered expression (>2-fold), 1 up-regulated (TNF) and 8 down-regulated (ESR1, MCL1, TBP, CD19, LCK, PCNA, CHEK1, and POLA1) hub proteins were defined. Among the down-regulated hub proteins, the most enriched biological process GO term and KEGG pathway were leading strand elongation and hsa05166:HTLV-I infection, respectively. This study reveals that H-CM had stronger anti-cancer effects on cervical cancer cells than N-CM and induced intracellular signaling patterns related to those enhanced anti-cancer effects.

Abstract
Cervical cancer (CC) is the 4th most prevalent malignancy in females. This study explored the mechanism of everolimus (RAD001) combined with programmed death-1 (PD-1) blockade on radiosensitivity by phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway and autophagy in CC cells. Low-radiosensitive CaSki cells were selected as study objects. After RAD001 treatment, PI3K/AKT/mTOR pathway activation, autophagy, migration and invasion abilities, autophagy-related proteins (LC3-I, LC3-II, and p62), and PD-L1 expression in CC cells were detected. After triple treatment of radiotherapy (RT), RAD001, and PD-1 blockade to the CC mouse models, tumor weight and volume were recorded. Ki67 expression, the number of CD8 + T cells, and the ability to produce IFN-γ and TNF-α in tumor tissues were determined. RAD001 promoted autophagy by repressing PI3K/AKT/mTOR pathway, augmented RT-induced apoptosis, and weakened migration and invasion, thereby increasing CC cell radiosensitivity. RAD001 elevated RT-induced PD-L1 level. RT combined with RAD001 and PD-1 blockade intensified the inhibitory effect of RT on tumor growth, reduced the amount of Ki67-positive cells, enhanced radiosensitivity of CC mice, and increased the quantity and killing ability of CD8 + T cells. Briefly, RAD001 combined with PD-1 blockade increases radiosensitivity of CC by impeding the PI3K/AKT/mTOR pathway and potentiating cell autophagy.

Abstract
The aim of this study is to identify potential biomarkers for early diagnosis of gynecologic cancer in order to improve survival. Cervical cancer (CC) and endometrial cancer (EC) are the most common malignant tumors of gynecologic cancer among women in the world. As the underlying molecular mechanisms in both cervical and endometrial cancer remain unclear, a comprehensive and systematic bioinformatics analysis is required. In our study, gene expression profiles of GSE9750, GES7803, GES63514, GES17025, GES115810, and GES36389 downloaded from Gene Expression Omnibus (GEO) were utilized to analyze differential gene expression between cancer and normal tissues. A total of 78 differentially expressed genes (DEGs) common to CC and EC were identified to perform the functional enrichment analyses, including gene ontology and pathway analysis. KEGG pathway analysis of 78 DEGs indicated that three main types of pathway participate in the mechanism of gynecologic cancer such as drug metabolism, signal transduction, and tumorigenesis and development. Furthermore, 20 diagnostic signatures were confirmed using the least absolute shrink and selection operator (LASSO) regression with 10-fold cross validation. Finally, we used the GEPIA2 online tool to verify the expression of 20 genes selected by the LASSO regression model. Among them, the expression of PAMR1 and SLC24A3 in tumor tissues was downregulated significantly compared to the normal tissue, and found to be statistically significant in survival rates between the CC and EC of patients (p < 0.05). The two genes have their function: (1.) PAMR1 is a tumor suppressor gene, and many studies have proven that overexpression of the gene markedly suppresses cell growth, especially in breast cancer and polycystic ovary syndrome; (2.) SLC24A3 is a sodium–calcium regulator of cells, and high SLC24A3 levels are associated with poor prognosis. In our study, the gene signatures can be used to predict CC and EC prognosis, which could provide novel clinical evidence to serve as a potential biomarker for future diagnosis and treatment.

Liu T, Yao Y, Xing X, Chu D. Effects of Continuous Catheterization on Reducing Postoperative Urinary Tract Infection in Cervical Cancer Patients with Double J Stent Placement. JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:9299001. [PMID: 34795888 PMCID: PMC8594985 DOI: 10.1155/2021/9299001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 10/01/2021] [Accepted: 10/22/2021] [Indexed: 11/18/2022]
Abstract
This study aims at exploring the effect of continuous catheterization on reducing postoperative urinary tract infection in cervical cancer patients with double J tube placement. To be specific, a retrospective analysis was performed on 120 cases of cervical cancer patients who underwent laparoscopic or open radical hysterectomy in Shengjing Hospital of China Medical University from January to December 2019. They were divided into a persistent group (n = 70) and a short-term group (n = 50) according to indwelling catheter time. The incidence of postoperative complications and the positive rate of bacterial culture in bladder urine and double J tube bacterial culture were compared between the two groups. As a result, it was found that the incidence of postoperative fever and urinary tract infection in the short-term group was significantly higher than that in the persistent group (P < 0.05). There was no significant difference in the incidence of postoperative hematuria, bladder stimulation, and urinary system injury between the two groups. The positive rate of double J tube bacterial culture in both groups was also proved to be higher than that in bladder culture, and the difference was statistically significant (P < 0.05). And in the short-term group (P < 0.05), the difference in the positive rate of bladder culture between the two groups was not statistically significant. To conclude, we found that continuous catheterization can reduce the incidence of postoperative urinary tract infection in cervical cancer patients with double J tube placement, which might be helpful for the treatment of cervical cancer.

Abstract
PURPOSE Almost all cervical cancers are caused by human papillomavirus (HPV) and patients with advanced stage are at high risk for relapse. Circulating HPV DNA (HPV ctDNA) may serve as a residual tumor marker at the end of chemoradiation or to predict relapse during the follow-up period. EXPERIMENTAL DESIGN We analyzed serum samples from 94 HPV16- or HPV18-related CCs from the BioRAIDs prospective cohort. Samples were collected before and after treatment and during an 18-month follow-up period. Using digital droplet PCR (ddPCR), we assessed the relevance of circulating HPV E7 gene as a marker for residual disease compared to HPV integration site and PIK3CA mutations. Finally, the prognostic impact of circulating HPV E7 gene was assessed with its prediction value of relapse. RESULTS HPV E7 gene was the most sensitive tumor marker, superior to both HPV integration sites and PIK3CA mutations in serum. Circulating HPV DNA (HPV ctDNA) was detected in 63% (59/94) of patients, before treatment. HPV ctDNA detection in serum sample was associated with high FIGO stage (P = 0.02) and para-aortic lymph node involvement (P = 0.01). The level of HPV ctDNA was positively correlated with HPV copy number in the tumor (R = 0.39, P < 0.001). Complete clearance of HPV ctDNA by the end of treatment was significantly associated with a longer PFS (P < 0.0001). Patients with persistent HPV ctDNA in serum relapsed with a median time of 10 months (range, 2-15) from HPV ctDNA detection. CONCLUSIONS HPV ctDNA detection is a useful marker to predict relapse in cervical cancer.See related commentary by Wentzensen and Clarke, p. 5733.

Abstract
Background Immune checkpoint inhibitors have aroused great expectation of tumor eradication. However, the effect of anti-PD-L1 treatment for cervical cancer is unsatisfactory and the underlying antagonist to anti-PD-L1 efficacy is remained to be studied. Here, we investigated the anti-tumor effect of anti-PD-L1 treatment in cervical tumor model and identified the antagonist to the therapeutic efficacy of anti-PD-L1 treatment. Results We found that PD-L1 exhibited a moderate expression in both cervical tumor cell lines and clinical samples compared to other tumor types and the para-tumor tissue respectively. Interestingly, our results showed that the anti-PD-L1 treated mice were dichotomously divided into responsive and unresponsive group after five cycles of anti-PD-L1 treatment although all the mice had the same genome background. In addition, the unresponsive tumors showed less tumor necrosis area and higher immunosuppression activity induced by regulatory T cells (Tregs) population than the responsive ones. Furthermore, we found that anti-PD-L1 treatment autonomously upregulated Tregs proliferation and frequency in multiple immune organs, and, most importantly, Tregs depletion significantly depressed the tumor growth rate and tumor weight compared with either anti-PD-L1 or anti-CD25 treatment alone. Finally, we observed that the upregulating effector CD8+ T cell is associated with the better therapeutic effect of anti-PD-L1 therapy post Tregs depletion. Conclusions Anti-PD-L1 treatment upregulates Tregs frequency and proliferation in tumor model, and the depletion of Tregs may be a useful adjuvant strategy for anti-PD-L1 therapy of cervical cancer.

Postreatment squamous cell carcinoma antigen as a survival prognostic factor in patients with locally advanced cervical cancer. A Spanish multicenter study. The SEGO Spain-GOG group. Gynecol Oncol 2021; 162:407-412. [PMID: 34119366 DOI: 10.1016/j.ygyno.2021.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 06/07/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To evaluate the clinical value of postreatment plasmatic levels of the squamous cell carcinoma antigen (SCC-Ag) as a survival independent prognostic factor in patients with LACC. METHODS Retrospective, multicenter study including LACC patients (FIGO 2009 stages IB2, IIA2-IVA) managed at the Gynecology Oncological Units corresponding to eight reference hospitals in Spain between 2000 and 2016. Receiver operating characteristic (ROC) curve analysis was used to determine the cut-off values of postreatment SCC-Ag levels in prediction of survival. Survival curves were calculated by using the Kaplan-Meier method and were compared with the log-rank test. Cox models were used to analyze different factors in terms of their prognosis predictive value. RESULTS The study included 447 patients with a median follow-up time of 53 months (IQR 26-101) and median pre- and postreatment SCC-Ag levels of 3.4 ng/ml (IQR 1.2-11) and 0.8 ng/ml (IQR 0.5-1.2), respectively. The cut-off level of pretreatment SCC-Ag was 11.75 ng/ml (sensibility 37.5%; specificity 80.5%) and that of postreatment SCC-Ag was 1.24 ng/ml (sensibility 34.6%; specificity 83.1%). In a multivariate Cox regression analysis, factors that were independent predictors of OS were: FIGO stage (HR 2.12; 95%CI 1.18-3.8; p = 0.011), paraaortic lymph node involvement (HR 3.56; 95%CI 2.04-6.2; p < 0.0001), postreatment SCC-Ag level ≥ 1.2 ng/ml (HR 1.95; 95%CI 1.11-3.44; p = 0.02) and incomplete response to treatment (HR 4.5; 95%CI 2.5-8.11; p < 0.0001). CONCLUSION Postreatment plasmatic SCC-Ag level ≥ 1.2 ng/ml was an independent risk factor for the survival of patients with LACC. Further factors influencing survival included: paraaortic lymph node involvement, advanced disease and poor response to concomitant chemoradiotherapy.

HPV ctDNA detection of high-risk HPV types during chemoradiotherapy for locally advanced cervical cancer. ESMO Open 2021; 6:100154.

Abstract
BACKGROUND Chemoradiotherapy (CRT) is the standard of care for patients diagnosed with locally advanced cervical cancer (LACC), a human papillomavirus (HPV)-related cancer that relapses in 30%-60% of patients. This study aimed to (i) design HPV droplet digital PCR (ddPCR) assays for blood detection (including rare genotypes) and (ii) monitor blood HPV circulating tumor DNA (HPV ctDNA) levels during CRT in patients with LACC. METHODS We analyzed blood and tumor samples from 55 patients with HPV-positive LACC treated by CRT in a retrospective cohort (n = 41) and a prospective cohort (n = 14). HPV-ctDNA detection was carried out by genotype-specific ddPCR. RESULTS HPV ctDNA was successfully detected in 69% of patients (n = 38/55) before CRT for LACC, including nine patients with a rare genotype. HPV-ctDNA level was correlated with HPV copy number in the tumor (r = 0.41, P < 0.001). HPV-ctDNA positivity for HPV18 (20%, n = 2/10) was significantly lower than for HPV16 (77%, n = 27/35) or other types (90%, n = 9/10, P = 0.002). HPV-ctDNA detection (positive versus negative) before CRT was associated with tumor stage (P = 0.037) and lymph node status (P = 0.02). Taking into account all samples from the end of CRT and during follow-up in the prospective cohort, positive HPV-ctDNA detection was associated with lower disease-free survival (DFS) (P = 0.048) and overall survival (OS) (P = 0.0013). CONCLUSION This is one of the largest studies to report HPV-ctDNA detection before CRT and showed clearance of HPV ctDNA at the end of treatment in most patients. Residual HPV ctDNA at the end of CRT or during follow-up could help to identify patients more likely to experience subsequent relapse.

[PMID: 32959937 DOI: 10.1002/jcb.29846] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 08/14/2020] [Accepted: 08/20/2020] [Indexed: 12/15/2022]
Abstract
Long noncoding RNAs (lncRNAs) have drawn growing attention due to their regulatory roles in various diseases, including tumors. Recently, lncRNA FOXD3 antisense RNA 1 (FOXD3-AS1) was shown to be overexpressed in colon adenocarcinoma and glioma, exerting oncogenic functions. However, its expression and effects in cervical cancer (CC) remained unknown. In this research, our group first reported that the levels of FOXD3-AS1 were distinctly elevated in CC samples and cell lines. The distinct upregulation of FOXD3-AS1 was associated with lymphatic invasion, distant metastasis, and International Federation of Gynecology and Obstetrics stage, and also predicted poor clinical results of CC patients. Next, transcription factor SP1 was demonstrated to resulting in the upregulation of FOXD3-AS1 in CC. Functional assays indicated that knockdown of FOXD3-AS1 distinctly suppressed CC progression via affecting cell proliferation, cell apoptosis, and metastasis. Moreover, mechanistic studies suggested that FOXD3-AS1 acted as an endogenous sponge by directly binding miR-296-5p, resulting in the suppression of miR-296-5p. In addition, we also reported that high mobility group A, a direct target of miR-296-5p, could mediate the tumor-promotive effects that FOXD3-AS1 displayed. Overall, our present study might help to lead a better understanding of the pathogenesis of CC, provide a novel possible tumor biomarker, and probe the feasibility of lncRNA-directed treatments for CC.

Abstract
Cervical cancer is the fourth most common cancer among women worldwide. Though several natural products have been reported regarding their efficacies against cervical cancer, there has been no review article that categorized them according to their anti-cancer mechanisms. In this study, anti-cancerous natural products against cervical cancer were collected using Pubmed (including Medline) and google scholar, published within three years. Their mechanisms were categorized as induction of apoptosis, inhibition of angiogenesis, inhibition of metastasis, reduction of resistance, and regulation of miRNAs. A total of 64 natural products suppressed cervical cancer. Among them, Penicillium sclerotiorum extracts from Cassia fistula L., ethanol extracts from Bauhinia variegate candida, thymoquinone obtained from Nigella sativa, lipid-soluble extracts of Pinellia pedatisecta Schott., and 1'S-1'-acetoxychavicol extracted from Alpinia conchigera have been shown to have multi-effects against cervical cancer. In conclusion, natural products could be attractive candidates for novel anti-cancer drugs.

Abstract
BACKGROUND Nowadays, the potential therapeutic role of various bioflavonoids including Curcumin, Luteolin and Resveratrol has currently been well-documented in a vast range of fatal complications including synaptic failure and cancers. These bioflavonoids are widely being implemented for the treatment of various cancers as they possess anti-cancerous, anti-oxidant and anti-inflammatory properties. Moreover, they are also used as a better alternative to conventional therapies since; these are non-toxic to cells and having no or least side effects. Notably, the pertinent therapeutic role of Rutin in cervical cancer is still unsettled however, its anti-cancerous role has already been reported in other cancers including prostate and colon cancer. Rutin (Vitamin P or Rutoside) is a polyphenolics flavonoid exhibiting multi-beneficial roles against several carcinomas. OBJECTIVE Despite the evidence for its several biological activities, the anticancer effects of Rutin on human cervical cancer (C33A) cells remain to be explored. In this study, the anticancer potential of Rutin was investigated by employing the key biomarkers such as nuclear condensation reactive oxygen species (ROS), apoptosis, and changes in mitochondrial membrane potential (MMP). RESULTS Our findings showed that Rutin treatment reduced the cell viability, induced significant increase in ROS production and nuclear condensation in dose-dependent manner. Moreover, Rutin provoked apoptosis by inducing decrease in MMP and activation of caspase-3. Cell cycle analysis further confirmed the efficacy of Rutin by showing cell cycle arrest at G0/G1 phase. CONCLUSION Thus, our study is envisaged to open up interests for elucidating Rutin as an anticancerous agent against cervical cancer.

Prognostic value of post-treatment ¹⁸F-fluorodeoxyglucose positron emission tomography in uterine cervical cancer patients treated with radiotherapy: a systematic review and meta-analysis. J Gynecol Oncol 2020; 30:e66. [PMID: 31328452 PMCID: PMC6658597 DOI: 10.3802/jgo.2019.30.e66] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 02/01/2019] [Accepted: 02/09/2019] [Indexed: 01/31/2023] Open
Abstract
Objectives To perform a systematic review and meta-analysis of the prognostic value of post-treatment 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in uterine cervical cancer patients treated with radiotherapy (RT) with or without chemotherapy. Methods PubMed and Embase databases were searched up to July 22, 2018, for studies which evaluated the response outcomes of 18F-FDG PET following RT, and their prognostic significance in uterine cervical cancer was assessed with overall survival (OS) or progression-free survival (PFS) as endpoints. Hazard ratios (HRs) were meta-analytically pooled using the random-effects model. Results Eleven studies with 12 patient cohorts including 1,104 patients were included. For a quantitative synthesis of OS, 7 cohorts were included. Two cohorts which reported disease-specific survival instead of OS were also included with flexibility. Pooled HR of complete metabolic response (CMR) compared to partial metabolic response (PMR) was 0.19 (95% confidence interval [CI]=0.11–0.31). Pooled HR of CMR compared to progressive metabolic disease (PMD) was more evident at 0.07 (95% CI=0.04–0.12), and that of CMR compared to both PMR and PMD was 0.20 (95% CI=0.12–0.34). Quantitative synthesis for PFS was performed with a total of 8 cohorts. Pooled HR of CMR was 0.17 (95% CI=0.10–0.29) compared to PMR, 0.02 (95% CI=0.01–0.06) compared to PMD and 0.12 (95% CI=0.07–0.19) compared to both PMR and PMD. Conclusion Response results of post-RT 18F-FDG PET were significant prognostic factors in patients with uterine cervical cancer, and 18F-FDG PET could be a reasonable follow-up imaging modality.

Abstract
Cancer cells undergo metabolic changes that support their malignant growth. These changes are often associated with increased expression of the rate-limiting glycolytic enzyme hexokinase 2. Hexokinase 2 is an enzyme that catalyzes the conversion of glucose to glucose-6-phosphate. In this study, we utilized Gene Expression Profiling Interactive Analysis (GEPIA) database analysis and clinical sample analysis to find that hexokinase 2 was highly expressed in cervical cancer. Furthermore, we found that high hexokinase 2 expression in cervical cancer demonstrated a positive correlation with tumor size (P = .009696), pathological grade (P = .028551), and prognosis (P = .00069) but not with age (P = .956201) or lymph node metastasis (P = .131379). At the cellular level, we knocked down the expression of hexokinase 2 in the human cervical cancer cell line SiHa. The results demonstrated that knockdown of hexokinase 2 inhibited the proliferation and migration of SiHa cells and promoted cell apoptosis. During this process, knockdown of hexokinase 2 inhibited phosphorylation of AKT and mammalian target of rapamycin and promoted p53 expression. At the same time, overexpression of human papillomavirus 18 oncogenes E6 and E7 significantly promoted the expression of hexokinase 2. Most importantly, we discovered a novel upstream regulatory microRNA for hexokinase 2: miR-9-5p. Luciferase reporter assays and Western blot assays demonstrated that hexokinase 2 expression was inhibited by miR-9-5p by directly binding its 3′-untranslated region in SiHa cells. Next, we determined that miR-9-5p could suppress the proliferation and migration of SiHa cells and induce apoptosis. In conclusion, we found that hexokinase 2 serves a carcinogenic role in cervical cancer through the miR-9-5p/hexokinase 2/AKT pathway, which serves as the basis for potential therapeutic targets and prognostic indicators.

Abstract
At present, the standard treatment approach for locally advanced cervical cancer is concurrent chemoradiotherapy (CCRT). An elevated pretreatment squamous cell carcinoma antigen (SCC Ag) level is associated with extensive tumors and poor survival for patients with cervical cancer treated with definitive CCRT. SCC Ag levels can be used to help physicians make decisions regarding surgery, avoiding the complications of double treatment modalities. Elevated SCC Ag is associated with radiotherapy resistance, and the rate of SCC Ag reduction during CCRT can predict tumor response after treatment. Moreover, the failure of SCC Ag levels to normalize posttreatment can predict tumor relapse, with a specificity higher than 70%, and adjuvant therapies should be considered for these patients. SCC Ag also plays an important role in the early detection of tumor relapse in patients with cervical cancer during follow-up after CCRT, with high sensitivity and good cost-effectiveness.

Abstract
Cervical cancer remains one of the main factors leading to tumor-related death worldwide. Many strategies of cancer treatment such as chemotherapy are developed and used nowadays. However, for the cancer chemotherapy resistance, reduction of the limitation of cancer chemotherapy efficacy is one of the aims of several oncology teams. Moreover, the cyclin-dependent kinase 4/6-cyclin D-retinoblastoma protein-E2F pathway is an important mechanism for cell cycle control and its dysregulation is one of the key factors for cancers development including cervical cancer. Ribociclib is one of the selective CDK4/6 inhibitors and is a new therapeutic approach showing promise as a good strategy of therapy in many human cancers. However, there are not the studies regarding the investigation of effects of Ribociclib in cervical cancer yet. In the present study, by western blotting and immunofluorescence assay, we found respectively that CDK4, CDK6 and cyclin D1 are highly expressed and are mostly localized in the nucleus with some localized in the cytoplasm of cervical cancer cell lines. Moreover, Ribociclib induced cell cycle arrest in G0-G1 phase and cell apoptosis, and inhibited C33A cell proliferation in dose - dependent manner following by decreased expression of certain related genes such as CDK4, CDK6, E2F1, P-Rb, and increased Bax expression. In C33A xenografts, Ribociclib inhibited tumor growth associated with decreased expressions of CDK4, CDK6, cyclin D1, Rb and Ki-67, and also significantly increased tumor cell apoptosis. However, we didn't find side effect of Ribociclib concerning heart, liver and kidney perturbation and any Ribociclib anti-tumor effects on HeLa in vitro and in vivo which may be due to Hela cell infection by HPV. Based on our findings, the Rb-E2F pathway can be considered as an important factor in human cervical cancer pathogenesis and as a mechanism of Ribociclib, a potential strategy of treatment for the improvement of new therapeutic measures for the treatment of HPV-negative cervical cancer which application for HPV-positive cervical cancer is desired in further study.

Abstract
Cervical cancer is one of the malignant tumors with high incidence and high mortality among women in developing countries. The main factors affecting the prognosis of cervical cancer are the late recurrence and metastasis and the effective adjuvant treatment, which is radiation and chemotherapy or combination therapy. Galectins, a family containing many carbohydrate binding proteins, are closely involved in the occurrence and development of tumor. They are involved in tumor cells transformation, angiogenesis, metastasis, immune escape, and sensitivity against radiation and chemotherapy. Therefore, galectins are deemed as the targets of multifunctional cancer treatment. In this review, we mainly focus on the role of galectins, especially galectin-1, galectin-3, galectin-7, and galectin-9 in cervical cancer, and provide theoretical basis for potential targeted treatment of cervical cancer.

Abstract
Objective Few data exist regarding adjuvant hysterectomy (AH) in locally advanced cervical cancer (LACC) patients treated with chemoradiotherapy. We investigated the effect of AH on prognosis in LACC patients, through meta-analysis. Methods EMBASE and MEDLINE databases and the Cochrane Library were searched for published studies comparing LACC patients who received AH after chemoradiotherapy with those who did not, through April 2016. Endpoints were mortality and recurrence rates. For pooled estimates of the effect of AH on mortality/recurrence, random- or fixed-effects meta-analytical models were used. Results Two randomized trials and six observational studies (AH following chemoradiotherapy, 630 patients; chemoradiotherapy, 585 patients) met our search criteria. Fixed-effects model-based meta-analysis indicated no significant difference in mortality between the groups (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.58–1.78; p=0.968) with low cross-study heterogeneity (p=0.73 and I2=0.0). This pattern was observed in subgroup analysis for study design, radiation type, response after chemoradiotherapy, and hysterectomy type. The pooled OR for AH and recurrence was 0.59 (95% CI=0.44–0.79; p<0.05) with low cross-study heterogeneity (p=0.29 and I2=17.8), favoring the AH group. However, this pattern was not observed in the subgroup analysis for the randomized trials. There was no evidence of publication bias. Conclusion In this meta-analysis, AH following chemoradiotherapy did not improve survival in patients with LACC, although it seemed to reduce the risk of recurrence. Concerning the significant morbidity of AH after chemoradiotherapy, routine use of AH should be avoided.

Positron emission tomography-magnetic resonance imaging (PET-MRI) for response assessment after radiation therapy of cervical carcinoma: a pilot study. EJNMMI Res 2018; 8:1. [PMID: 29292485 PMCID: PMC5748389 DOI: 10.1186/s13550-017-0352-6] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2017] [Accepted: 12/14/2017] [Indexed: 01/05/2023] Open
Abstract
Background Advanced stage cervical cancer is primarily treated by radiotherapy. Local tumor control is a prerequisite for cure. Imaging after treatment is controversial. Positron emission tomography (PET) combined with computer tomography (PET-CT) shows great promise for detecting metastases. On the other hand, magnetic resonance imaging (MRI) is superior in depicting anatomical details. The combination of PET-MRI could result in more accurate evaluation of cervical cancer treatment outcome. The aim of this pilot study is to share our initial experience with PET-MRI in the evaluation of treatment response in cervical cancer after radiation treatment. Methods Ten patients with cervical carcinoma (FIGO ≥IB2) were prospectively evaluated. Eleven weeks (median; range 8–15 weeks) after radiation therapy, treatment response was evaluated by PET-MRI. The PET, MRI, and combined PET-MRI images were evaluated for the presence of local residual tumor and metastasis. Diagnostic performance was assessed by area under the receiver operator characteristic (ROC) curve for evaluation of local residual tumor. The readers were blinded for outcome data. Local residual disease, metastasis, diagnostic confidence, and change of opinion were scored on a 5-point Likert scale. The reference standard consisted of pathology and/or follow-up according to the clinical guidelines. Results Three out of ten patients had local residual abnormalities suggestive for tumor residue after radiation treatment. The availability of both PET and MRI resulted in an increase in diagnostic confidence in 80–90% of all patients. Change of opinion was observed in 70% and change of policy in 50%, especially in the group with residual tumor. The diagnostic accuracy increased significantly for the radiologist if PET-MRI was combined (AUC .54 versus .83). Conclusions PET-MRI shows promise for evaluation of treatment response after radiation for cervical cancer, especially increasing diagnostic confidence, while potentially increasing diagnostic performance.
