Abstract
Background Ferroptosis is a non-apoptotic iron-dependent form of cell death implicated in various cancer pathologies. However, its precise role in tumor growth and progression of cervical cancer (CC) remains unclear. Transferrin receptor protein 1 (TFRC), a key molecule associated with ferroptosis, has been identified as influencing a broad range of pathological processes in different cancers. However, the prognostic significance of TFRC in CC remains unclear. The present study utilized bioinformatics to explore the significance of the ferroptosis-related gene TFRC in the progression and prognosis of CC. Methods We obtained RNA sequencing data and corresponding clinical information on patients with CC from The Cancer Genome Atlas (TCGA), Genotype Tissue Expression (GTEx) and Gene Expression Omnibus (GEO) databases. Using least absolute shrinkage and selection operator (LASSO) Cox regression, we then generated a multigene signature of five ferroptosis-related genes (FRGs) for the prognostic prediction of CC. We investigated the relationship between TFRC gene expression and immune cell infiltration by employing single-sample GSEA (ssGSEA) analysis. The potential functional role of the TFRC gene was evaluated through gene set enrichment analysis (GSEA). Immunohistochemistry and qPCR was employed to assess TFRC mRNA and protein expression in 33 cases of cervical cancer. Furthermore, the relationship between TFRC mRNA expression and overall survival (OS) was investigated in patients. Results CC samples had significantly higher TFRC gene expression levels than normal tissue samples. Higher TFRC gene expression levels were strongly associated with higher cancer T stages and OS events. The findings of multivariate analyses illustrated that the OS in CC patients with high TFRC expression is shorter than in patients with low TFRC expression. Significant increases were observed in the levels of TFRC mRNA and protein expression in patients diagnosed with CC. Conclusion Increased TFRC expression in CC was associated with disease progression, an unfavorable prognosis, and dysregulated immune cell infiltration. In addition, it highlights ferroptosis as a promising therapeutic target for CC.

Estimation of economic burden throughout course of cervical squamous intraepithelial lesion and cervical cancer in China: A nationwide multicenter cross-sectional study. Chin J Cancer Res 2023; 35:675-685. [PMID: 38204443 PMCID: PMC10774142 DOI: 10.21147/j.issn.1000-9604.2023.06.11] [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: 09/24/2023] [Accepted: 11/15/2023] [Indexed: 01/12/2024] Open
Abstract
Objective Cervical squamous intraepithelial lesion (SIL) and cervical cancer are major threats to females' health and life in China, and we aimed to estimate the economic burden associated with their diagnosis and treatment. Methods A nationwide multicenter, cross-sectional, hospital-based survey was conducted in 26 qualified hospitals across seven administrative regions of China. We investigated females who had been pathologically diagnosed with SIL and cervical cancer, and included five disease courses ("diagnosis", "initial treatment", "chemoradiotherapy", "follow-up" and "recurrence/progression/metastasis") to estimate the total costs. The median and interquartile range (IQR) of total costs (including direct medical, direct non-medical, and indirect costs), reimbursement rate by medical insurance, and catastrophic health expenditures in every clinical stage were calculated. Results A total of 3,471 patients in different clinical stages were analyzed, including low-grade SIL (LSIL) (n=549), high-grade SIL (HSIL) (n=803), cervical cancer stage IA (n=226), IB (n=610), IIA (n=487), IIB (n=282), III (n=452) and IV (n=62). In urban areas, the estimated total costs of LSIL and HSIL were [Formula: see text]1,637.7 (IQR: [Formula: see text]956.4-[Formula: see text]2,669.2) and [Formula: see text]2,467.1 (IQR: [Formula: see text]1,579.1-[Formula: see text]3,762.3), while in rural areas the costs were [Formula: see text]459.0 (IQR: [Formula: see text]167.7-[Formula: see text]1,330.3) and [Formula: see text]1,230.5 (IQR: [Formula: see text]560.6-[Formula: see text]2,104.5), respectively. For patients with cervical cancer stage IA, IB, IIA, IIB, and III-IV, the total costs were [Formula: see text]15,034.9 (IQR: [Formula: see text]11,083.4-[Formula: see text]21,632.4), [Formula: see text]19,438.6 (IQR: [Formula: see text]14,060.0-[Formula: see text]26,505.9), [Formula: see text]22,968.8 (IQR: [Formula: see text]16,068.8-[Formula: see text]34,615.9), [Formula: see text]26,936.0 (IQR: [Formula: see text]18,176.6-[Formula: see text]41,386.0) and [Formula: see text]27,332.6 (IQR: [Formula: see text]17,538.7-[Formula: see text]44,897.0), respectively. Medical insurance covered 43%-55% of direct medical costs for cervical cancer patients, while the coverage for SIL patients was 19%-43%. For most cervical cancer patients, the expense was catastrophic, and the extent of catastrophic health expenditure was about twice large for rural patients than that for urban patients in each stage. Conclusions The economic burden of SIL and cervical cancer in China is substantial, with a significant proportion of the costs being avoidable for patients with LSIL. Even for those with medical insurance, catastrophic health expenditures are also a major concern for patients with cervical cancer, particularly for those living in rural areas.

Cost-effectiveness of the screen-and-treat strategies using HPV test linked to thermal ablation for cervical cancer prevention in China: a modeling study. BMC Med 2023; 21:149. [PMID: 37069602 PMCID: PMC10111823 DOI: 10.1186/s12916-023-02840-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 03/20/2023] [Indexed: 04/19/2023] Open
Abstract
BACKGROUND Self-sampling HPV test and thermal ablation are effective tools to increase screening coverage and treatment compliance for accelerating cervical cancer elimination. We assessed the cost-effectiveness of their combined strategies to inform accessible, affordable, and acceptable cervical cancer prevention strategies. METHODS We developed a hybrid model to evaluate costs, health outcomes, and incremental cost-effectiveness ratios (ICER) of six screen-and-treat strategies combining HPV testing (self-sampling or physician-sampling), triage modalities (HPV genotyping, colposcopy or none) and thermal ablation, from a societal perspective. A designated initial cohort of 100,000 females born in 2015 was considered. Strategies with an ICER less than the Chinese gross domestic product (GDP) per capita ($10,350) were considered highly cost-effective. RESULTS Compared with current strategies in China (physician-HPV with genotype or cytology triage), all screen-and-treat strategies are cost-effective and self-HPV without triage is optimal with the most incremental quality-adjusted life-years (QALYs) gained (220 to 440) in rural and urban China. Each screen-and-treat strategy based on self-collected samples is cost-saving compared with current strategies (-$818,430 to -$3540) whereas more costs are incurred using physician-collected samples compared with current physician-HPV with genotype triage (+$20,840 to +$182,840). For screen-and-treat strategies without triage, more costs (+$9404 to +$380,217) would be invested in the screening and treatment of precancerous lesions rather than the cancer treatment compared with the current screening strategies. Notably, however, more than 81.6% of HPV-positive women would be overtreated. If triaged with HPV 7 types or HPV16/18 genotypes, 79.1% or 67.2% (respectively) of HPV-positive women would be overtreated with fewer cancer cases avoided (19 cases or 69 cases). CONCLUSIONS Screen-and-treat strategy using self-sampling HPV test linked to thermal ablation could be the most cost-effective for cervical cancer prevention in China. Additional triage with quality-assured performance could reduce overtreatment and remains highly cost-effective compared with current strategies.

Abstract
Objective To evaluate the clinical value of different combination strategies of high-risk HPV (hr-HPV) testing and Thinprep cytology test (TCT), a cervical cytology test, for cervical cancer screening, especially for high or higher-grade squamous intraepithelial lesion (HSIL+) in Shuangliu District, Chengdu City. Methods The study is a population-based randomized clinical trial. Women aged 35 to 65 years meeting the inclusion criteria were enrolled for the study. At the baseline screening conducted in the first year, the participants were randomly assigned to either cytology test or hr-HPV testing at a ratio of 1∶2. If the paticipants had positive results for the baseline hr-HPV test, they would then undergo either cytology test or colposcopy by random assignment. After 24 months, all participants were called back, and combined screening of cytology test and hr-HPV test were performed. Women who had negative results at baseline screening and who entered and completed the third-year follow-up were selected as the subjects of the study. Based on the aforementioned testing findings, the related data were extracted and four different screening protocols were simulated: 1) combined TCT and hr-HPV screening, with referral for colposcopy when there was positive results for either one of the two; 2) combined TCT and hr-HPV screening, with referral for colposcopy when both tests had positive results at the same time; 3) TCT was done for preliminary screening and those who were found to be positive would then undergo hr-HPV test for triage purpose, with subsequent referral made for colposcopy if the hr-HPV results were positive; 4) hr-HPV was done for preliminary screening and those who were found to be positive would then undergo TCT, with subsequent referral made for colposcopy if TCT results were positive. With the detection of HSIL+ on histological examination as the endpoint event, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under curve ( AUC) of different combination screening models were calculated. Results A total of 3102 women were screened, and 2967 women were included in the statistical analysis in this study. Among the 2967 women, 979 were randomized to cytology and 1988 to hr-HPV genotyping. For prescreening, the positive rate of the cytology group was 5.6% (55/979), with of HSIL+ positive rate being 0.2% (2/979), while the positive rate of the hr-HPV group was 7.5% (149/1988), with HSIL+ positive rate being 0.9% (18/1988). After 24 months, 2456 women were called back and were given cervical cytology test and hr-HPV test at the same time. Among them, the positive rate of the cytology group was 3.2% (78/2456), while the positive rate of hr-HPV group was 8.7% (215/2456). The overall positive rate of HSIL+ was 0.69%(17/2456). Women with a negative baseline hr-HPV had a lower incidence of HSIL+ lesions in the long term. The strategy of cervical cytology screening combined with hr-HPV test for triage purpose is the best method, with a sensitivity of 88.9%, a specificity of 58.3%, a PPV of 44.4%, a NPV of 93.3%, and an AUC of 0.736, P=0.039 (95% CI: 0.555-0.917). Conclusion This randomized clinical trial from Shuangliu District, Chengdu City shows that the sensitivity of hr-HPV testing is better than that of cytology test, and the prevalence of HSIL+ in women with negative baseline hr-HPV results is lower than that of women with negative baseline cytology results. The screening program of TCT for prescreening plus subsequent hr-HPV test for triage purpose shows better value for the detection of HSIL+.

Abstract
OBJECTIVE The aims of this systematic review were to (1) identify primary- and model-based economic evaluations of cervical cancer screening methods and to (2) provide a contextual summary of valuation outcomes associated with three types of cervical cancer screening tests: visual inspection with acetic acid, human papillomavirus deoxyribonucleic acid, and Papanicolaou smear. INTRODUCTION Cervical cancer screening is an important public health priority with the potential to improve the detection of precancerous lesions in high-risk females for early intervention and disease prevention. Test performance and cost-effectiveness differ based on the specific screening method used across different platforms. There is a need to appraise existing economic evaluations of cervical cancer screening methods. METHODS This review considered primary-based and model-based full economic evaluations of cervical cancer screening methods. The evaluation methods of interest included cost-effectiveness analysis, cost-utility analysis, cost-minimization analysis, cost-benefit analysis, and cost-consequence analysis. We searched Scopus, PubMed, National Health Economic Evaluation Database (NH EED), Cochrane, and the Health Economic Evaluation Database for full economic evaluations of cancer screening methods. No formal date restrictions were applied. Model-based and primary-based full economic evaluations were included. A critical appraisal of included studies was performed by the main investigator, while a second independent reviewer assessed critical appraisal findings for any inconsistencies. Data were extracted using a standardised data extraction tool for economic evaluations. The ultimate outcomes of costs, effectiveness, benefits, and utilities of cervical cancer screening modalities were extracted from included studies, analysed, and summarised. RESULTS From a total of 671 screened studies, 44 studies met the study inclusion criteria. Forty-three studies were cost-effectiveness analyses, one study reported both cost-utility and cost-effectiveness outcomes, and another study reported cost utilities of cervical cancer screening methods only. Human papillomavirus (HPV) DNA testing was reported as a dominant stand-alone screening test by 14 studies, while five studies reported visual inspection with acetic acid (VIA) as a dominant stand-alone screening test. Primary HPV screening strategies were dominant in 21 studies, while three studies reported cytology-based screening strategies as the dominant screening method. CONCLUSIONS Existing evidence indicates that HPV-based and VIA testing strategies are cost-effective, but this is dependent on setting. Our review suggests the limited cost-effectiveness of cytology-based testing, which may be due in part to the need for specific infrastructures and human resources.

Abstract
OBJECTIVE To describe the trends of incidence and mortality of cervical cancer in different age groups and regions from 1990 to 2019. DESIGN An international comparative study based on the Global Burden of Disease (GBD) study estimates. PARTICIPANTS Data were publicly available and individuals were not involved. METHODS We collected detailed information on cervical cancer from the GBD study between 1990 and 2019. Average annual percentage changes (AAPCs) of age-standardised incidence and mortality rate (ASIR and ASMR) in cervical cancer, by age group and region, were calculated to quantify the temporal trends. RESULTS Globally, the absolute numbers of incident cases and deaths were increasing, with the most cervical cancer cases and deaths being reported in China, India and Brazil. Although the ASIR and ASMR have declined overall from 1990 to 2019, an increasing or stable trend was also observed in East Asia and Southern sub-Saharan Africa. Particularly, we found that the age-specific AAPC of incidence showed an increasing trend in the age group of 15-49 years globally, and the high Sociodemographic Index region increased the most. CONCLUSIONS Cervical cancer remains a concerning disease that affects women all over the world, although the ASIR and ASMR are decreasing. Efforts to control the younger trend and to reduce the disparity between regions are imminent.

Abstract
OBJECTIVES To estimate the lifetime treatment costs of patients with human papillomavirus (HPV) infection-related diseases in China and to provide cost estimates for the economic evaluation of HPV intervention strategies. METHODS We extracted real-world hospital data from 2012 to 2019 and screened for subjects who met the criteria of clinical diagnosis of HPV-related diseases to obtain country-specific inputs into a Markov decision model. The model simulated lifetime treatment costs for HPV from the perspective of a national payer. A 5% discount rate was applied. Costs were converted and inflated to 2020 US dollars (USD). RESULTS Using 2021 as the base year, the lifetime costs per patient for carcinoma in situ, local metastasis, and distant metastasis cervical cancer are $24,208 (95%CI: 18,793-30,897), $19,562 (95%CI: 14,456-25,567), and $17,599 (95%CI: 10,604-25,807), respectively. For carcinoma in situ, local metastasis, and distant metastasis vaginal cancer, the lifetime costs are $17,593 (95%CI: 14,962-23,596), $17,120 (95%CI: 13,215-22,417), and $22,411 (95%CI: 12,172-22,249), respectively. The base-case lifetime cost per patient for different stages of vulvar cancer/penile cancer/anal cancer/oral cancer/oropharyngeal cancer/laryngeal cancer falls within $17,120-$58,236. CONCLUSIONS Using real-world data, we calculated lifetime treatment costs of HPV-related cancer in China and found that the lifetime cost for patients exceeded $17,000 for various stages of disease. The national burden of HPV-related disease could be significantly reduced by eliminating HPV infection.

Effectiveness and cost-effectiveness of eliminating cervical cancer through a tailored optimal pathway: a modeling study. BMC Med 2021; 19:62.

Abstract
BACKGROUND The World Health Assembly has adopted a global strategy to eliminate cervical cancer. However, neither the optimal pathway nor the corresponding economic and health benefits have been evaluated. We take China as an example to assess the optimal pathway towards elimination and the cost-effectiveness of tailored actions. METHODS A validated hybrid model was used to assess the costs and benefits of alternative strategies combining human papillomavirus vaccination, cervical screening, and treatment of pre-invasive lesions and invasive cancer for females with different immunization history. All Chinese females living or projected to be born during 2015-2100, under projected trends in aging, urbanization, and sexual activity, were considered. Optimal strategies were determined by cost-effectiveness efficiency frontiers. Primary outcomes were cervical cancer cases and deaths averted and incremental cost-effectiveness ratios (ICERs). We employed a lifetime horizon from a societal perspective. One-way and probabilistic sensitivity analyses evaluate model uncertainty. RESULTS The optimal pathway represents an integration of multiple tailored strategies from females with different immunization history. If China adopts the optimal pathway, the age-standardized incidence of cervical cancer is predicted to decrease to fewer than four new cases per 100,000 women (i.e., elimination) by 2047 (95% confidence interval 2043 to 2050). Compared to the status quo, the optimal pathway would avert a total of 7,509,192 (6,922,744 to 8,359,074) cervical cancer cases and 2,529,873 (2,366,826 to 2,802,604) cervical cancer deaths in 2021-2100, with the discounted ICER being $- 339 (- 687 to - 79) per quality-adjusted life-year. CONCLUSIONS By adopting an optimal pathway from 2021 (namely, the year of the first Chinese Centennial Goals) onwards, cervical cancer could be eliminated by the late 2040s (namely, ahead of the second Chinese Centennial Goals) while saving net economic costs in China.

Abstract
Question Does integration of high-risk human papillomavirus (hrHPV) testing into China’s national screening program lead to better outcomes than current primary screening approaches? Findings In this randomized clinical trial that included 60 732 women, hrHPV testing as primary screening provided a 2.0-fold to 2.7-fold yield for cervical intraepithelial neoplasia grade 2 or worse and grade 3 or worse compared with cytology or visual inspection with acetic acid and Lugol iodine at baseline. It also resulted in a significantly lower risk of cervical intraepithelial neoplasia grade 2 or worse and grade 3 or worse for baseline-negative women under routine conditions in primary health care settings in rural areas across China. Meaning It is reasonable to incorporate hrHPV testing (polymerase chain reaction–based testing for urban areas, hybrid capture–based testing for rural areas) as a primary screening method into China’s current national screening program. Importance Evidence is needed regarding the introduction of high-risk human papillomavirus (hrHPV) testing into China’s national cervical cancer screening program. Objective To evaluate hrHPV testing as a new screening modality for the national program. Design, Setting, and Participants This population-based, multicenter, open-label, randomized clinical trial took place across 20 primary health care centers in urban and rural areas across China. At least 3000 women aged 35 to 64 years per site were invited to participate, for a total of 60 732 women evaluated. Interventions At baseline, women were randomly assigned to cytology, hrHPV testing, or visual inspection with acetic acid and Lugol iodine (VIA/VILI) (rural only). Women who tested positive for hrHPV were randomized into cytology-triage, VIA/VILI-triage (rural only), or direct colposcopy arms. Regarding primary or triaging tests, women with cytological abnormalities or who tested positive with VIA/VILI were referred to colposcopy. After 24 months, combined screening of cytology, hrHPV testing, and VIA/VILI was performed, and all women with positive results were referred to colposcopy. Main Outcomes and Measures The primary outcomes were cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and CIN3+ yields. The secondary outcome was colposcopy referral rate. Results A total of 60 732 women were included in this study, with median (interquartile range) age of 47 (41-52) years. Among urban women, 8955 were randomized to cytology and 18 176 to hrHPV genotyping; among rural women, 11 136 were randomized to VIA/VILI, 7080 to cytology, and 15 385 to hrHPV testing. Participants who tested positive for hrHPV with direct colposcopy had higher risk ratios for disease yields at baseline (urban hrHPV vs cytology, CIN2+ 2.2 [95% CI, 1.6-3.2] and CIN3+ 2.0 [95% CI, 1.2-3.3]; rural hrHPV vs cytology, 2.6 [95% CI, 1.9-4.0] and 2.7 [95% CI, 2.0-3.6]; rural hrHPV vs VIA/VILI, 2.0 [95% CI, 1.6-2.3] and 2.3 [95% CI, 1.8-3.1]). At 24 months, baseline-negative women in the hrHPV arm had significantly lower risk ratios than those with cytology, or VIA/VILI for CIN2+ (0.3 [95% CI, 0.2-0.5], 0.3 [95% CI, 0.2-0.6]) and CIN3+ (0.3 [95% CI, 0.1-0.6], 0.4 [95% CI, 0.2-0.8]) in rural sites. The colposcopy referral rate for hrHPV-positive rural women was reduced to 2.8% by cytology triage, with significantly higher CIN2+ yields than cytology (2.1 [95% CI, 1.3-2.6]) or VIA/VILI arm (1.6 [95% CI, 1.03-2.1]). Genotyping for hrHPV with cytology triage significantly reduced the colposcopy referral rate compared with cytology (0.8 [95% CI, 0.7-0.9]) for urban women. Conclusions and Relevance In this randomized clinical trial, testing for hrHPV was an effective primary screening method in primary health care centers. Incorporating hrHPV testing (polymerase chain reaction–based for urban areas, hybrid capture-based for rural areas) into China’s national screening program is reasonable.

Health economic evaluation of primary human papillomavirus screening in urban populations in China. Cancer Epidemiol 2020; 70:101861. [PMID: 33310688 DOI: 10.1016/j.canep.2020.101861] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 10/02/2020] [Accepted: 11/15/2020] [Indexed: 01/29/2023]
Abstract
BACKGROUND On Nov 17, 2020, WHO launched a global initiative to accelerate the elimination of cervical cancer through the implementation of HPV vaccination, cervical cancer screening and treatment for precancer and cancer. China has the largest burden of cervical cancer in the world, but only has a national cervical cancer screening program in rural areas since 2009. Here, we aimed to evaluate the effectiveness and cost-effectiveness of cervical cancer screening in urban China, using Shenzhen City as an example. METHODS We use an extensively validated platform ('Policy1-Cervix'), calibrated to data from Shenzhen city and Guandong Province. We evaluated a range of strategies that have previously been implemented as pilot studies in China, or recommended as guidelines within China and globally, spanning primary HPV, cytology and co-testing strategies. We additionally considered alternate triaging methods, age ranges and screening intervals, resulting in 19 algorithms in total. RESULTS Of the 19 strategies considered, the most effective approach involved primary HPV testing. At 3- to 10-yearly intervals, primary HPV testing reduced the age-standardized cancer mortality rate by 37-71 %. The most cost-effective strategy was 5-yearly primary HPV testing with partial genotyping triage for ages 25-65, discharging to 10-yearly screening for low-risk women (ICER = US$7191/QALYS using 2018 costs; willingness-to-pay threshold<1xGDP [US$9771]). This strategy gave an incidence and mortality reduction of 56 % and 63 %, respectively. This remained the most cost-effective strategy under most conditions in sensitivity analysis. CONCLUSION Primary HPV testing would be cost-effective in Shenzhen and could more than halve cervical cancer incidence rates to 6 per 100,000 over the long term. In order to achieve rates below 4 per 100,000, the elimination threshold set by the World Health Organization, vaccination will likely also be necessary.
