Cervical cancer risk and screening among women seeking assistance with basic needs

Socioeconomic inequalities in cervical cancer mortality in Canada, 1990 and 2019: a trend analysis

OBJECTIVE

It is increasingly recognized that those of lower socioeconomic status (SES) are disproportionately affected by cancer mortality. The association between cervical cancer mortality and SES have been reported; however, it remains poorly understood in the Canadian population. Thus, this study investigates trends in income and education inequalities in cervical cancer mortality in Canada over the last three decades.

STUDY DESIGN

Trend analysis.

METHODS

A dataset constructed at the census division level (n = 280), comprising the Canadian Vital Statistics Death Database, the Canadian Census of Population, and the National Household Survey was used to measure cervical cancer mortality in Canada. Income and education inequalities in cervical cancer mortality were measured using age-standardized Concentration index (C).

RESULTS

Crude cervical cancer mortality rates decreased significantly during the study period. Age-standardized C values were negative for the majority of years for income and education inequalities, reaching significance in some years. Trend analyses indicated an increasing concentration of cervical cancer mortality amongst those with lower education levels.

CONCLUSION

Despite recent decreases in cervical cancer mortality rates, socioeconomic inequalities in cervical cancer mortality in Canada are persistent. Notably, those of lower income and education levels are disproportionately affected, underscoring an opportunity to improve clinical outcomes by addressing these inequalities.

An Intervention-Based Approach to Achieve Racial Equity in Gynecologic Oncology

Racial inequities within gynecologic oncology exist at every step of the cancer continuum. Although the disparities have been well described, there is a significant gap in the literature focused on eliminating inequities in gynecologic cancer outcomes. The goal of this narrative review is to highlight successful, evidence-based interventions from within and outside of gynecologic oncology that alleviate disparity, providing a call to action for further research and implementation efforts within the field. These solutions are organized in the socioecologic framework, where multiple levels of influence-societal, community, organizational, interpersonal, and individual-affect health outcomes.

Social determinants of health and US cancer screening interventions: A systematic review

There remains a need to synthesize linkages between social determinants of health (SDOH) and cancer screening to reduce persistent inequities contributing to the US cancer burden. The authors conducted a systematic review of US-based breast, cervical, colorectal, and lung cancer screening intervention studies to summarize how SDOH have been considered in interventions and relationships between SDOH and screening. Five databases were searched for peer-reviewed research articles published in English between 2010 and 2021. The Covidence software platform was used to screen articles and extract data using a standardized template. Data items included study and intervention characteristics, SDOH intervention components and measures, and screening outcomes. The findings were summarized using descriptive statistics and narratives. The review included 144 studies among diverse population groups. SDOH interventions increased screening rates overall by a median of 8.4 percentage points (interquartile interval, 1.8-18.8 percentage points). The objective of most interventions was to increase community demand (90.3%) and access (84.0%) to screening. SDOH interventions related to health care access and quality were most prevalent (227 unique intervention components). Other SDOH, including educational, social/community, environmental, and economic factors, were less common (90, 52, 21, and zero intervention components, respectively). Studies that included analyses of health policy, access to care, and lower costs yielded the largest proportions of favorable associations with screening outcomes. SDOH were predominantly measured at the individual level. This review describes how SDOH have been considered in the design and evaluation of cancer screening interventions and effect sizes for SDOH interventions. Findings may guide future intervention and implementation research aiming to reduce US screening inequities.

Value of T lymphocyte subset detection in cervical intraepithelial neoplasia

OBJECTIVE

This study aimed to explore the value of T lymphocyte subset detection in cervical intraepithelial neoplasia (CIN).

METHODS

In this retrospective analysis, T lymphocyte subsets in 186 CIN patients were detected. Venous blood T lymphocyte subsets were analyzed in patients with different CIN grades, and Spearman correlation analysis was conducted between CIN grade and T lymphocyte subsets.

RESULTS

(1) There were significant differences in the CD3+, CD4+, CD8+, and CD4+/CD8+ levels before and 1, 2, and 3 months after treatment (P<0.05). Furthermore, significant differences were found in CD3+, CD4+, CD8+, and CD4+/CD8+ between every pair of time points (P<0.05). (2) Comparison of human papillomavirus distribution in patients with different CIN grades showed P<0.05. (3) The level of T lymphocyte subsets in the venous blood of patients with different CIN grades was compared, and significant differences were found, P<0.05. Higher CIN grade was associated with lower levels of CD3+, CD4+ and CD4+/CD8+, as well as higher level of CD8+. (4) Spearman analysis showed that CIN grade was negatively correlated with the levels of CD3+, CD4+, and CD4+/CD8+ (P<0.05) and positively correlated with the level of CD8+ (P<0.05).

CONCLUSION

The levels of T lymphocyte subsets were found to be closely associated with the severity of CIN. Therefore, the detection of T lymphocyte subsets in venous blood could be a valuable clinical tool for predicting the presence and degree of CIN.

Combined incentive actions, focusing on primary care professionals, to improve cervical cancer screening in women living in socioeconomically disadvantaged geographical areas: a study protocol of a hybrid cluster randomised effectiveness and implementation trial- RESISTE

INTRODUCTION

Cervical cancer (CC) causes thousands of deaths each year. Nearly 100% of cases are caused by oncogenic strains of human papillomavirus (HPV). In most industrialised countries, CC screening (CCS) is based on the detection of HPV infections. For many reasons including lower adherence to CCS, underserved women are more likely to develop CC, and die from it. We aim to demonstrate that the use of incentives could improve screening rates among this population.

METHODS AND ANALYSIS

Our cluster randomised, controlled trial will include 10 000 women aged 30-65 years eligible for CCS, living in deprived areas in four French departments, two mainlands and two overseas, and who did not perform physician-based HPV testing within the framework of the nationally organised screening programme. HPV self-sampling kit (HPVss) will be mailed to them. Two interventions are combined in a factorial analysis design ending in four arms: the possibility to receive or not a financial incentive of €20 and to send back the self-sampling by mail or to give it to a health professional, family doctor, gynaecologist, midwife or pharmacist. The main outcome is the proportion of women returning the HPVss, or doing a physician-based HPV or pap-smear test the year after receiving the HPVss. 12-month follow-up data will be collected through the French National Health Insurance database. We expect to increase the return rate of HPV self-samples by at least 10% (from 20% to 30%) compared with the postal return without economic incentive.

ETHICS AND DISSEMINATION

Ethics approval was first obtained on 2 April 2020, then on July 29 2022. The ethics committee classified the study as interventional with low risk, thus no formal consent is required for inclusion. The use of health insurance data was approved by the Commission Nationale Informatique et Libertés on 14 September 2021 (ref No 920276). An independent data security and monitoring committee was established. The main trial results will be submitted for publication in a peer-reviewed journal.

Effectiveness and feasibility of self-sampling for human papillomavirus testing for internet-based cervical cancer screening

Objectives

Worldwide, around 18.2% of cervical cancer occurred in China, mainly because of lower screening coverage and screening quality in regional disparities. To assess self-sampling for human papillomavirus (HPV) testing, combined with the internet, as a primary cervical cancer screening (CCS) method in low-resource settings, and to establish an internet-based self-sampling CCS-management model.

Methods

The women who participated registered on a CCS website. We recruited 20,136 women, aged 30-59 years, from 13 provinces in China, to perform vaginal self-sampling for HPV testing as a primary CCS, based on the internet. A questionnaire was subsequently used to investigate the acceptability of self-sampling.

Results

Of the 20,103 women with qualified samples, 35.80% lived in remote areas, 37.69% had never undergone CCS, 59.96% were under-screened, and the overall prevalence of a high-risk of HPV was 13.86%. Of 8,136 respondents, 95.97% of women felt that self-sampling was easy to perform, 84.61% had no discomfort when using a self-sampling brush, 62.37% women were more likely to choose self-sampling for CCS in future, and 92.53% were willing to introduce the concept to others around them. The reliability and ease of self-sampling were independent factors influencing selection of self-sampling (p < 0.05).

Conclusions

The Internet-facilitated self-sampling for HPV testing and management model for cervical cancer prevention is feasible and effective. It can be used as a supplement to the conventional screening, particularly in outlying areas with few medical resources, to improve the coverage of CCS.

Evaluation of Implementation Effect of Cervical Cancer Comprehensive Treatment Patients With Whole-Course High-Quality Care Combined With Network Continuation Care

Purpose

Discuss the implementation effect of cervical cancer comprehensive treatment patients applying whole-course high-quality care combined with network continuation care.

Methods

From August 2020 to August 2021, 120 patients who met the inclusion criteria for comprehensive treatment of cervical cancer were divided into the regular group (n = 60) who received conventional care and the joint group (n = 60) who received whole-course high-quality care combined with network continuation care, according to the method of care. The comprehensive treatment cognition level, comprehensive treatment compliance, adverse reaction rate, quality of life questionnaire (QLQ-C30) score, self-rating anxiety/depression scale (SAS/SDS) score, and nursing satisfaction were compared between the two groups.

Results

After care, the comprehensive treatment cognition score and comprehensive treatment compliance score were higher in the joint group than in the regular group (P < 0.05). After care, the incidence of radiation cystitis and radiation proctitis was lower in the joint group than that in the regular group (P < 0.05). After care, QLQ-C30 scores on symptom domains, functional domains, and single questions were higher in both groups than before care, and were higher in the joint group than in the regular group (P < 0.05). After care, SAS and SDS scores were lower in both groups than before care, and were lower in the joint group than in the regular group (P < 0.05). After care, the joint group was more satisfied with care than the regular group (P < 0.05).

Conclusion

The implementation of cervical cancer comprehensive treatment patients with whole-course high-quality care combined with network continuation care has an ideal implementation effect, which can significantly increase the patient's cognition and compliance with treatment, the incidence of adverse reactions is less, the quality of life and emotional state have also improved significantly, and care satisfaction has also increased accordingly.
