Colorectal Cancer: A Collaborative Approach to Improve Education and Screening in a Rural Population

Cancer screening educational interventions in rural and farmworker communities: a systematic literature review

OBJECTIVES

Men and women living in rural communities of the United States (US) are less likely than those in urban or suburban communities to be up to date with cancer screenings. Delayed screening contributes to later stage at diagnosis and higher cancer mortality for individuals living in rural areas. These effects may be compounded in some rural subpopulations (e.g. migrant and seasonal farmworkers). This systematic review examines educational interventions aimed at increasing colorectal, breast, prostate, oral, and/or cervical cancer screening in the rural US, with special consideration for the farmworker subpopulation.

DESIGN

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, our systematic literature review employed the following databases: Ovid MEDLINE, CINAHL Complete, Embase, and Web of Science. Search terms included, but were not limited to 'rural,' 'cancer screening,' 'farmworker,' and 'cancer prevention.' Eligible studies featured an educational intervention implemented in agricultural or rural US settings with a cancer screening behavioral outcome, male and/or female participants, and were published in English between 2002 and 2020. Article screening and data extraction were conducted by two independent reviewers.

RESULTS

Twenty-six articles were eligible. Of the six studies focused on the farmworker population (n=2,732), 61.75% of participants reported Hispanic ethnicity. Of the sixteen studies on unspecified rural communities reporting participant race/ethnicity (n=10,442), 39.29% reported Black/African American race. Efficacious interventions included culturally-targeted educational materials, lay health advisors (LHAs), and components that addressed practical barriers (e.g. financial or logistical).

CONCLUSION

Results demonstrate the value of LHAs and targeted education to increase screening for multiple cancer types in rural communities. Prospective research should incorporate and facilitate access to screening and provider-level and/or organizational-level interventions to increase overall impact.

Assessing the use of constructs from the consolidated framework for implementation research in U.S. rural cancer screening promotion programs: a systematic search and scoping review

BACKGROUND

Cancer screening is suboptimal in rural areas, and interventions are needed to improve uptake. The Consolidated Framework for Implementation Research (CFIR) is a widely-used implementation science framework to optimize planning and delivery of evidence-based interventions, which may be particularly useful for screening promotion in rural areas. We examined the discussion of CFIR-defined domains and constructs in programs to improve cancer screening in rural areas.

METHODS

We conducted a systematic search of research databases (e.g., Medline, CINAHL) to identify studies (published through November 2022) of cancer screening promotion programs delivered in rural areas in the United States. We identified 166 records, and 15 studies were included. Next, two reviewers used a standardized abstraction tool to conduct a critical scoping review of CFIR constructs in rural cancer screening promotion programs.

RESULTS

Each study reported at least some CFIR domains and constructs, but studies varied in how they were reported. Broadly, constructs from the domains of Process, Intervention, and Outer setting were commonly reported, but constructs from the domains of Inner setting and Individuals were less commonly reported. The most common constructs were planning (100% of studies reporting), followed by adaptability, cosmopolitanism, and reflecting and evaluating (86.7% for each). No studies reported tension for change, self-efficacy, or opinion leader.

CONCLUSIONS

Leveraging CFIR in the planning and delivery of cancer screening promotion programs in rural areas can improve program implementation. Additional studies are needed to evaluate the impact of underutilized CFIR domains, i.e., Inner setting and Individuals, on cancer screening programs.

Rural-Urban Differences in Esophagectomy for Cancer

Introduction

Patients who are disadvantaged socioeconomically or live in rural areas may not pursue surgery at high-volume centers where outcomes are better for some complex procedures. The objective of this study was to compare rural and urban patient differences directly by location of residence and outcomes after undergoing esophagectomy for cancer.

Methods

An analysis of the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) database was performed, capturing adult patients with esophageal cancer who underwent esophagectomy. Patients were stratified into rural or urban groups by the National Center for Health Statistics Urban-Rural Classification Scheme. Demographics, hospital variables, and outcomes were compared.

Results

A total of 2,877 patients undergoing esophagectomy for esophageal cancer were captured by the database, with 228 (7.92%) rural and 2,575 (89.50%) urban patients. The rural and urban groups had no differences in age, race, and insurance status, and shared many common comorbidities. Major outcomes of mortality (3.95% versus 4.27%, p = 0.815) and length of stay (15.75 ± 13.22 vs. 15.55 ± 14.91 days, p = 0.828) were similar for both rural and urban patients. There was a trend for rural patients to more likely be discharged home (35.96% vs. 29.79%, OR 0.667 [95% CI 0.479 – 0.929]; p = 0.0167).

Conclusions

This retrospective administrative database study indicated that rural and urban patients received equivalent postoperative care after undergoing esophagectomy. The findings were reassuring as there did not appear to be a disparity in major outcomes depending on the location of residence, but further studies are necessary to assure equitable treatment for rural patients.

Advocacy and Collaboration: Advancing Cancer Prevention and Screening

BACKGROUND

Cancer prevention and screening is a significant part of the cancer care continuum. Nurses are trusted professionals who can bring stakeholders together and serve diverse groups.

OBJECTIVES

This article describes how nurses can advance cancer prevention and screening initiatives in industry, education, legislative advocacy, research, survivorship, and program development and support.

METHODS

An online search and collaborative knowledge revealed examples of nurses leading the way in cancer prevention and screening efforts.

FINDINGS

Nurse-driven cancer prevention and screening collaborations advance care farther and faster. By creating maximum impact and mobilizing individual passion for a project, any nurse can find collaborative niche opportunities in clinical practice.

LncRNA SNHG6 inhibits cell proliferation and metastasis by targeting ETS1 via the PI3K/AKT/mTOR pathway in colorectal cancer

The term ‘long non-coding RNAs’ (lncRNAs) refers to all non-protein coding transcripts >200 nucleotides in length. Dysregulation of lncRNAs has been identified in colorectal cancer, which is one of the more serious types of cancer worldwide, third place in the mortality rates, and is associated with poor prognoses. Novel evidence suggests that lncRNAs serve an important role in regulating the development and progression of colorectal cancer. In the present study, it was demonstrated that SNHG6 expression was downregulated in colorectal cancer tissues by reverse transcription quantitative polymerase chain reaction assays; however, ETS1 expression levels were upregulated. Overexpression of SNHG6 not only inhibited the proliferation of colon cancer cells in vitro by inducing apoptosis, but also inhibited cell proliferation, invasion and migration. The overexpression of SNHG6 inhibited colon cell viability and proliferation by targeting ETS1 through the phosphoinositide 3-kinase/protein kinase B/mechanistic target of rapamycin signaling pathway. These results suggested that SNHG6 may directly suppress ETS1, which may be one of potential mechanisms through which it inhibits the viability and proliferation of colorectal cancer cells, and it provides novel insight into the carcinogenesis of colorectal cancer. In addition, it may assist in the development of a treatment approach for ETS1-activated colorectal cancer.
