Chem Biol Interact 2024; 396:111058. [PMID: 38761877 DOI: 10.1016/j.cbi.2024.111058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 05/13/2024] [Accepted: 05/15/2024] [Indexed: 05/20/2024]
Abstract
Pterostilbene (PTE), a natural phenolic compound, has exhibited promising anticancer properties in the preclinical treatment of cervical cancer (CC). This study aims to comprehensively investigate the potential targets and mechanisms underlying PTE's anticancer effects in CC, thereby providing a theoretical foundation for its future clinical application and development. To accomplish this, we employed a range of methodologies, including network pharmacology, bioinformatics, and computer simulation, with specific techniques such as WGCNA, PPI network construction, ROC curve analysis, KM survival analysis, GO functional enrichment, KEGG pathway enrichment, molecular docking, MDS, and single-gene GSEA. Utilizing eight drug target prediction databases, we have identified a total of 532 potential targets for PTE. By combining CC-related genes from the GeneCards disease database with significant genes derived from WGCNA analysis of the GSE63514 dataset, we obtained 7915 unique CC-related genes. By analyzing the intersection of the 7915 CC-related genes and the 2810 genes that impact overall survival time in CC, we identified 690 genes as crucial for CC. Through the use of a Venn diagram, we discovered 36 overlapping targets shared by PTE and CC. We have constructed a PPI network and identified 9 core candidate targets. ROC and KM curve analyses subsequently revealed IL1B, EGFR, IL1A, JUN, MYC, MMP1, MMP3, and ANXA5 as the key targets modulated by PTE in CC. GO and KEGG pathway enrichment analyses indicated significant enrichment of these key targets, primarily in the MAPK and IL-17 signaling pathways. Molecular docking analysis verified the effective binding of PTE to all nine key targets. MDS results showed that the protein-ligand complex between MMP1 and PTE was the most stable among the nine targets. Additionally, GSEA enrichment analysis suggested a potential link between elevated MMP1 expression and the activation of the IL-17 signaling pathway. In conclusion, our study has identified key targets and uncovered the molecular mechanism behind PTE's anticancer activity in CC, establishing a firm theoretical basis for further exploration of PTE's pharmacological effects in CC therapy.

[PMID: 38703493 DOI: 10.1016/j.puhe.2024.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/25/2024] [Accepted: 04/03/2024] [Indexed: 05/06/2024]
Abstract
OBJECTIVES Cardiovascular diseases (CVDs) and neoplasms have been considered as public health concerns worldwide. This study aimed to estimate the epidemiological patterns of death burden on CVDs and neoplasms and its attributable risk factors in Western Europe from 1990 to 2019 to discuss the potential causes of the disparities. STUDY DESIGN AND METHODS We collected data on CVDs and neoplasms deaths in 24 Western European countries from the Global Burden of Disease Study. We analyzed patterns by age, sex, country, and associated risk factors. The results include percentages of total deaths, age-standardized death rates per 100,000 population, and uncertainty intervals (UIs). Time trends were assessed using annual percent change. RESULTS In 2019, CVDs and neoplasms accounted for 33.54% and 30.15% of Western Europe's total deaths, with age-standardized death rates of 128.05 (95% UI: 135.37, 113.02) and 137.51 (95% UI: 142.54, 128.01) per 100,000. Over 1990-2019, CVDs rates decreased by 54.97%, and neoplasms rates decreased by 19.54%. Top CVDs subtypes were ischemic heart disease and stroke; top cancers for neoplasms were lung and colorectal. Highest CVD death burdens were in Finland, Greece, Austria; neoplasm burdens in Monaco, San Marino, Andorra. The major risk factors were metabolic (CVDs) and behavioral (neoplasms). Gender differences revealed higher CVDs death burden in males, while neoplasms burden varied by risk factors and age groups. CONCLUSION In 2019, CVDs and neoplasms posed significant health risks in Western Europe, with variations in death burdens and risk factors across genders, age groups, and countries. Future interventions should target vulnerable groups to lessen the impact of CVDs and neoplasms in the region.

Impact of high-performance human papillomavirus testing to improve cervical cancer screening in China: a prospective population-based multicentre cohort study. Clin Microbiol Infect 2024:S1198-743X(24)00166-6.

Abstract
OBJECTIVES The aim of the study was to evaluate the clinical performance of HBRT-H14, a real-time PCR-based assay that separates human papillomavirus (HPV) 16 and HPV18 from 12 other high-risk (HR) HPV types, in population according to Chinese guideline. METHODS A total of 9829 eligible women aged 21-64 years from Henan, Shanxi, and Guangdong provinces were performed by HBRT-H14 testing and liquid-based cytology (LBC) screening at baseline and followed up for 3-year. The sensitivity, specificity, positive predictive value (absolute risk), and negative predictive value of LBC diagnosis and HPV testing were calculated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+) Lesions. RESULTS At baseline, 80 (0.81%) participants were diagnosed with CIN2+. HR-HPV with reflex LBC had a significantly higher sensitivity (78/80, 97.50% [95% CI, 91.34-99.31%] vs. 62/80, 77.50% [67.21-85.27%], McNemar's test p < 0.001), and a slightly lower specificity (8528/9749, 87.48% [86.80-88.12%] vs. 8900/9749, 91.29% [90.72-91.83%], McNemar's test p < 0.001) than LBC with reflex HR-HPV for CIN2+. 7832 (79.6%) participants completed 3-year follow-up and 172 (2.20%) participants were cumulatively diagnosed with CIN2+. Compared with LBC with reflex HR-HPV, HR-HPV with reflex LBC significantly increased the sensitivity (161/172, 93.60% [88.91-96.39%] vs. 87/172, 50.58% [43.18-57.96%], McNemar's test p < 0.001), but marginally decreased the specificity (6776/7660, 88.46% [87.72-89.16%] vs. 6933/7660, 90.51% [89.83-91.15], McNemar's test p < 0.001). In addition, the absolute 3-year risk of CIN2+ in HPV16/18-positive individuals was as high as 33% (80/238), whereas the risk in the HPV-negative population was only 0.16% (11/6787), much lower than those in the negative for intraepithelial lesion or malignancy population (1.21%, 85/7018). Moreover, similar results were found in women ≥30 years old. DISCUSSION The study has indicated that HBRT-14 has a reliable clinical performance for use in cervical screening. The validated HPV test would improve the quality of population screening.

Glutathione Depletion-Induced Versatile Nanomedicine for Potentiating the Ferroptosis to Overcome Solid Tumor Radioresistance and Enhance Immunotherapy. Adv Healthc Mater 2024; 13:e2303412.

Abstract
A high level of reduced glutathione is a major factor contributing to the radioresistance observed in solid tumors. To address this radioresistance associated with glutathione, a cinnamaldehyde (CA) polymer prodrug, referred to as PDPCA, is fabricated. This prodrug is created by synthesizing a pendent CA prodrug with acetal linkages in a hydrophobic block, forming a self-assembled into a core-shell nanoparticle in aqueous media. Additionally, it encapsulates all-trans retinoic acid (ATRA) for synchronous delivery, resulting in PDPCA@ATRA. The PDPCA@ATRA nanoparticles accumulate reactive oxygen species through both endogenous and exogenous pathways, enhancing ferroptosis by depleting glutathione. This approach demonstrates efficacy in overcoming tumor radioresistance in vivo and in vitro, promoting the ferroptosis, and enhancing the cytotoxic T lymphocyte (CTL) response for lung tumors to anti-PD-1 (αPD-1) immunotherapy. Furthermore, this study reveals that PDPCA@ATRA nanoparticles promote ferroptosis through the NRF2-GPX4 signaling pathway, suggesting the potential for further investigation into the combination of radiotherapy and αPD-1 immune checkpoint inhibitors in cancer treatment.

Cervical Cancer Screening via Visual Inspection With Acetic Acid and Lugol Iodine for Triage of HPV-Positive Women. JAMA Netw Open 2024; 7:e244090. [PMID: 38551562 PMCID: PMC10980959 DOI: 10.1001/jamanetworkopen.2024.4090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 02/01/2024] [Indexed: 04/01/2024] Open
Abstract
Importance Limited evidence supports the performance of human papillomavirus (HPV) DNA testing as a primary screening method, followed by triage with visual inspection with acetic acid, in areas with limited health care resources, as suggested by the 2021 World Health Organization guidelines. Objective To evaluate the performance of visual inspection with acetic acid and Lugol iodine as a triage method for detecting cervical precancerous lesions among HPV-positive women in 1 visit. Design, Setting, and Participants This cohort study examined the implementation of a government-led cervical cancer screening program conducted from January 1, 2016, to December 31, 2020, in Ordos City, China. Female residents, aged 35 to 64 years, who understood the screening procedures and voluntarily participated were included in the study. Women were excluded if they reported never having had sexual intercourse, were pregnant, had a hysterectomy, or had ever undergone treatment for cervical lesions. Statistical analysis was conducted from December 2022 to December 2023. Exposures The program used the careHPV DNA assay as the primary screening method, and immediate triage was performed by visual inspection if HPV screening results were positive, with a 5-year screening interval. A colposcopy was performed for the women who had suspected cancer on visual inspection results or who were HPV positive and had abnormal visual inspection results, all in 1 visit. Main Outcomes and Measures The rate of compliance with colposcopy and the detection rate of cervical intraepithelial neoplasia grade 2 or higher (CIN2+). Results The study included 187 863 women (median age, 46 years [IQR, 40-52 years]) who participated in the program and had valid HPV test results. The overall prevalence of HPV positivity was 12.8% (24 070 of 187 863), and the adherence to triage with visual inspection among HPV-positive women was 93.9% (22 592 of 24 070). Among HPV-positive women, the rate of compliance with colposcopy was 65.6% (2714 of 4137), and the CIN2+ detection rate was 2.8% (643 of 22 592). Conclusions and Relevance The findings of this cohort study suggest that the implementation of HPV testing, visual inspection, and colposcopy within 1 visit may mitigate losses to follow-up, detect precancerous lesions, and hold significant implications for screening in comparable areas with limited health care resources.

Development and validation of a 18F-FDG PET/CT radiomics nomogram for predicting progression free survival in locally advanced cervical cancer: a retrospective multicenter study. BMC Cancer 2024; 24:150. [PMID: 38291351 PMCID: PMC10826285 DOI: 10.1186/s12885-024-11917-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/24/2024] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND The existing staging system cannot meet the needs of accurate survival prediction. Accurate survival prediction for locally advanced cervical cancer (LACC) patients who have undergone concurrent radiochemotherapy (CCRT) can improve their treatment management. Thus, this present study aimed to develop and validate radiomics models based on pretreatment 18Fluorine-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)-computed tomography (CT) images to accurately predict the prognosis in patients. METHODS The data from 190 consecutive patients with LACC who underwent pretreatment 18F-FDG PET-CT and CCRT at two cancer hospitals were retrospectively analyzed; 176 patients from the same hospital were randomly divided into training (n = 117) and internal validation (n = 50) cohorts. Clinical features were selected from the training cohort using univariate and multivariate Cox proportional hazards models; radiomic features were extracted from PET and CT images and filtered using least absolute shrinkage and selection operator and Cox proportional hazard regression. Three prediction models and a nomogram were then constructed using the previously selected clinical, CT and PET radiomics features. The external validation cohort that was used to validate the models included 23 patients with LACC from another cancer hospital. The predictive performance of the constructed models was evaluated using receiver operator characteristic curves, Kaplan Meier curves, and a nomogram. RESULTS In total, one clinical, one PET radiomics, and three CT radiomics features were significantly associated with progression-free survival in the training cohort. Across all three cohorts, the combined model displayed better efficacy and clinical utility than any of these parameters alone in predicting 3-year progression-free survival (area under curve: 0.661, 0.718, and 0.775; C-index: 0.698, 0.724, and 0.705, respectively) and 5-year progression-free survival (area under curve: 0.661, 0.711, and 0.767; C-index, 0.698, 0.722, and 0.676, respectively). On subsequent construction of a nomogram, the calibration curve demonstrated good agreement between actually observed and nomogram-predicted values. CONCLUSIONS In this study, a clinico-radiomics prediction model was developed and successfully validated using an independent external validation cohort. The nomogram incorporating radiomics and clinical features could be a useful clinical tool for the early and accurate assessment of long-term prognosis in patients with LACC patients who undergo concurrent chemoradiotherapy.

Abstract
AIM Evidence showed self-efficacy was relevant to rural females' cervical cancer screening behaviour. However, little is known about sources of self-efficacy in cervical cancer screening among rural females. This study aimed to explore sources of self-efficacy in cervical cancer screening among rural females. DESIGN A qualitative descriptive study was conducted. Both users and providers of cervical cancer screening services in rural areas of China were recruited through maximum variation sampling. METHODS Individual semi-structured interviews through telephone calls were conducted. Data were analysed via six main stages of the framework method, with the social cognitive theory as a reference. RESULTS Four main sources were identified, including personal screening experience, hearing about other women's screening experiences, professional health education and consultation, and emotional status. Personal screening experience included enactive mastery of completing the screening behaviour and cognitive mastery of internalisation of the screening. Only the experience of completing cervical cancer screening behaviour was not strong enough to improve self-efficacy. Cognitive mastery showed more critical influence. CONCLUSION These four sources of rural females' cervical cancer screening self-efficacy matched with the major sources of self-efficacy of the social cognitive theory. Cognition was critical to influencing the screening self-efficacy. Intervention strategies aimed at enhancing rural females' cervical cancer screening self-efficacy can be developed from these four major sources. PUBLIC CONTRIBUTION A registered nurse with rich experience in cervical cancer-related research and qualitative study was the interviewer of this study. Rural females and cervical cancer screening services providers (healthcare professionals and village staff) were recruited as interviewees. The interview guides were developed by the research team and evaluated by an expert panel including two nurse leaders of gynaecological cancer, one doctor specialised in cervical cancer, and one medical director in a local rural hospital.

Abstract
OBJECTIVE Some studies have reported that the prognosis of total laparoscopic hysterectomy (TLH) for early-stage cervical cancer (CC) is worse than that of open surgery. And this was associated with the use of uterine manipulator or not. Therefore, this study retrospectively analyzes the efficacy and safety of TLH without uterine manipulator combined with pelvic lymphadenectomy for early-stage CC. METHODS Fifty-eight patients with CC (stage IB1-IIA1) who received radical hysterectomy from September 2019 to January 2020 were divided into no uterine manipulator (n = 26) and uterine manipulator group (n = 32). Then, clinical characteristics were collected and intraoperative/postoperative related indicators were compared. RESULTS Patients in the no uterine manipulator group had significantly higher operation time and blood loss than in the uterine manipulator group. Notably, there was no significant difference in hemoglobin change, blood transfusion rate, number of pelvic nodules, anal exhaust time, complications and recurrence rate between the two groups. Additionally, patients in the uterine manipulator group were prone to urinary retention (15.6%) and lymphocyst (12.5%), while the no uterine manipulator group exhibited high probability of bladder dysfunction (23.1%) and urinary retention (15.4%). Furthermore, the 1-year disease-free survival rate and the 1-year overall survival rate were not significantly different between the two groups. CONCLUSION There was no significant difference in the efficacy and safety of TLH with or without uterine manipulator combined with pelvic lymphadenectomy in the treatment of patients with early-stage CC. However, the latter requires consideration of the negative effects of high operation time and blood loss.

Abstract
This study aimed to investigate the expression and function of substance P in cervical squamous cell carcinoma. Cancer tissues and adjacent tissues of 20 patients with cervical squamous cell carcinoma in our hospital were collected. The expression of substance P was detected by immunohistochemistry and Western blot analysis. Cervical squamous cell carcinoma line SiHa was treated with different concentrations of substance P. The proliferation of SiHa cells was detected by EdU assay, and the invasion ability of SiHa cells was detected by transwell assay. The phosphorylation of ERK1/2 and the expression of MMP9 were detected by Western blot analysis. The results showed that substance P was expressed in the cytoplasm and some cell membranes of cervical squamous cell carcinoma cells. The expression of substance P in cervical cancer tissues was significantly higher than that in the adjacent tissues. Compared with the control group, substance P significantly promoted the proliferation and invasion of SiHa cells in a concentration dependent manner and activated the phosphorylation of ERK1/2 and upregulated the expression of MMP9 in SiHa cells. In conclusion, substance P is highly expressed in cervical squamous cell carcinoma and can promote cervical cancer cell proliferation and invasion. The mechanism is related to the activation of ERK1/2 pathway to upregulate MMP9.

Abstract
Triple-negative breast cancers (TNBC) represent a pathological subtype of breast cancer, which are characterized by strong invasiveness, high metastasis rate, low survival rate, and poor prognosis, especially in patients who have developed resistance to multiline treatments. Here, we present a female patient with advanced TNBC who progressed despite multiple lines of treatments; next-generation sequencing (NGS) was used to find drug mutation targets, which revealed a coiled-coil domain-containing protein 6 (CCDC6)-rearranged during transfection (RET) gene fusion mutation. The patient was then given pralsetinib, and after one treatment cycle, a CT scan revealed partial remission and adequate tolerance to therapy. Pralsetinib (BLU-667) is a RET-selective protein tyrosine kinase inhibitor that can inhibit the phosphorylation of RET and downstream molecules as well as the proliferation of cells expressing RET gene mutations. This is the first case in the literature of metastatic TNBC with CCDC6-RET fusion treated with pralsetinib, an RET-specific antagonist. This case demonstrates the potential efficacy of pralsetinib in cases of TNBC with RET fusion mutations and suggests that NGS may reveal new opportunities and bring new therapeutic interventions to patients with refractory TNBC.

Abstract
The SPF10-polymerase chain reaction (PCR)-based line probe assay (LiPA-25) with high analytical sensitivity and specificity for human papillomavirus (HPV) genotyping in clinical samples has been widely used in vaccine and epidemiologic studies. A real-time multiplex PCR assay using type-specific primers (Hybribio-23) with low workload and cost has been developed recently. The study aimed to compare the performance of LiPA-25 and Hybribio-23 in selected 1731 cervical swab and 117 tissue samples, with a focus on 20 common HPV types (14 high-risk: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68/73; 6 low-risk: 6, 11, 42, 43, 44, and 53). The level of agreement of two assays was determined using Cohen's Kappa (κ) statistics. A total of 1296 (74.9%) swab samples were identified as HPV-positive by Hybribio-23 or LiPA-25, of which 814 (62.8%) samples exhibited concordant, 358 (27.6%) showed additional or fewer types (compatible), and 124 (9.6%) were discordant. In addition, the two assays showed a perfect agreement for 20 HPV-combined detection (κ = 0.838) and 17 individual HPV types (all κ > 0.800), a good agreement for HPV31 (κ = 0.792) and 43 (κ = 0.696), and a moderate agreement for HPV42 (κ = 0.504). Hybribio-23 was significantly more sensitive for HPV58, 59, 68/73, 42, 43, and 44, and less sensitive for HPV35 and 66 than LiPA-25 (McNemar's test: all p < 0.05). For 117 HPV-positive tissue specimens, the identification of genotypes was 85.2% identical, 12.2% compatible, and only 2.6% discordant. The agreement for HPV31 (κ = 0.786), 68/73 (κ = 0.742), and HPV53 (κ = 0.742) was good, while for other types (all κ > 0.853) and 20 HPV-combined detection (κ = 0.936) was perfect (all p > 0.05). In conclusion, Hybribio-23 and LiPA-25 are comparable. Hybribio-23 could be used for the detection and genotyping of HPV in cervical samples for epidemiological and vaccine studies worldwide.

Abstract
The SPF10-PCR-based line probe assay (LiPA-25) for human papillomavirus (HPV) genotyping with high analytical sensitivity and specificity was widely used in HPV vaccine clinical trials and epidemiologic studies. In the study, we aimed to compare a novel GP5+/6+-PCR-based reverse dot blot hybridization assay (Yaneng-23) with LiPA-25. The performance of two assays was evaluated in 1735 cervical swab and 117 tissue samples, with a focus on 19 common HPV types (14 high-risk: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68/73; 5 low-risk: 6, 11, 42, 43, and 53). A total of 1197 (69.0%) swab samples were identified as HPV-positive by two assays. Of these, 878 (73.4%) samples displayed absolute agreement (concordant), 255 (21.3%) showed additional or fewer types (compatible), and the remaining 64 (5.3%) samples were discordant. Additionally, the two assays showed an excellent strength of agreement for 19 HPV-combined detection (κ = 0.886) and 17 individual HPV types (all κ > 0.800), and displayed a good agreement for HPV39 (κ = 0.780) and 42 (κ = 0.699). Yaneng-23 was more sensitive than LiPA-25 for HPV58, 59, 68/73, 42, 43 and 53 (McNemar's test: all p < 0.05), while LiPA-25 was more sensitive for HPV31, 39, 52, and 66 than Yaneng-23 (all p < 0.05). In 113 HPV-positive tissue specimens, the identification of genotypes was 82.3% identical and 17.7% compatible. The agreement between the tests for HPV45 (κ = 0.796) and 51 (κ = 0.742) was good, and for other types (all κ > 0.843) and 19 HPV-combined detection (κ = 0.929) was perfect (all p > 0.05).

Abstract
Radiotherapy suffers from its high-dose radiation-induced systemic toxicity and radioresistance caused by the immunosuppressive tumor microenvironment. Immunotherapy using checkpoint blocking in solid tumors shows limited anticancer efficacy due to insufficient T-cell infiltration and inadequate systemic immune responses. Activation and guiding of irradiation by X-ray (AGuIX) nanoparticles with sizes below 5 nm have entered a phase III clinical trial as efficient radiosensitizers. This study aimed to develop a unique synergistic strategy based on AGuIX-mediated radiotherapy and immune checkpoint blockade to further improve the efficiency for B16 tumor therapy. AGuIX exacerbated radiation-induced DNA damage, cell cycle arrest, and apoptosis on B16 cells. More importantly, it could efficiently induce the immunogenic cell death of irradiated B16 tumor cells, and consequently trigger the maturation of dendritic cells and activation of systemic T-cell responses. Combining AGuIX-mediated radiotherapy with programmed cell death protein 1 blockade demonstrated excellent synergistic therapeutic effects in both bilateral and metastatic B16 tumor models, as indicated by a significant increase in the infiltration of effector CD8+ T cells and effective alleviation of the immunosuppressive tumor microenvironment. Our findings indicate that the synergy between radiosensitization and immunomodulation provides a new and powerful therapy regimen to achieve durable antitumor T-cell responses, which is promising for cancer treatment.
