Effect of rurality and socioeconomic deprivation on presentation stage and long-term outcomes in patients undergoing surgery for colorectal cancer

Socioeconomic disadvantage and its impact on colorectal cancer in Australia: a scoping review

BACKGROUND

Social disparities in cancer survival have been demonstrated in Australia despite a universal healthcare insurance system. Colorectal cancer is common, and reasons for survival disparities related to socioeconomic status need to be investigated and addressed. The aim is to evaluate the current Australian literature concerning the impact of socioeconomic status on colorectal cancer survival and stage at presentation.

METHODS

A systematic search of PUBMED, EMBASE, SCOPUS and Clarivate Web of Science databases from January 2010 to March 2022 was performed. Studies investigating the impact of socioeconomic status on colorectal stage at presentation or survival in Australia were included. Data were extracted on author, year of publication, state or territory of origin, patient population, other exposure variables, outcomes and findings and adjustments made.

RESULTS

Of the 14 articles included, the patient populations examined varied in size from 207 to 100 000+ cases. Evidence that socioeconomic disadvantage was associated with poorer survival was demonstrated in eight of 12 studies. Evidence of effect on late stage at presentation was demonstrated in two of seven studies. Area-level measures were commonly used to assess socioeconomic status, with varying indices utilized.

CONCLUSION

There is limited evidence that socioeconomic status is associated with late-stage at presentation. More studies provide evidence of an association between socioeconomic disadvantage and poorer survival, especially larger studies utilizing less clinically-detailed cancer registry data. Further investigation is required to analyse why socioeconomic disadvantage may be associated with poorer survival.

Recovery of Health and Wellbeing in Rural Cancer Survivors Following Primary Treatment: Analysis of UK Qualitative Interview Data

Purpose: Rural cancer survivors have poorer experiences and health outcomes compared to their urban counterparts. There is limited research on the post-treatment experiences of UK cancer survivors residing in rural areas. This study aimed to provide an understanding of the specific challenges and opportunities faced by rural cancer survivors and to provide insight into how rurality influences experiences post-primary treatment, ultimately to inform service provision. Methods: A secondary analysis of in-depth interview transcripts (n = 16) from a wider study on self-management in cancer survivors was conducted. An adapted version of Foster and Fenlon’s recovery of health and wellbeing in cancer survivorship framework informed the data coding. Results: Health and wellbeing were interrupted by a variety of problem incidents, and the subsequent steps to recovery were influenced by pre-existing, personal, environmental, and healthcare factors. A prominent theme was support, both from local communities and family as well as from healthcare professionals, with many survivors feeling that their rural setting had a positive influence on their health and wellbeing. Close relationships with local GPs were seen as fundamental to supporting recovery. Access to healthcare was frequently mentioned as a challenge with an emphasis on lengthy travel times and limited bespoke support in rural areas. Conclusions: This study is novel in that it applied a well-established theoretical framework to a rich qualitative dataset on the lived experiences of rural cancer survivors. Rural residency influenced recovery from cancer both positively and negatively. Implications for Cancer Survivors: Future practitioners and policy makers should consider working with local communities to tailor interventions to the specific characteristics of the rural environment.

Influence of Race, Insurance, Rurality, and Socioeconomic Status on Equity of Lung and Colorectal Cancer Care

BACKGROUND

This study evaluated the influence that social determinants of health had on stage at diagnosis and receipt of cancer-directed surgery for patients with lung and colorectal cancer in the North Carolina Central Cancer Registry (2010-2015).

METHODS

This study examined non-Hispanic uninsured or privately-insured patients 18 to 64 years of age. Multivariable logistic regression models, including two-way interaction terms, assessed the influence of race, insurance status, rurality, and Social Deprivation Index on stage at diagnosis and receipt of surgery.

RESULTS

6574 lung cancer patients and 5355 colorectal cancer patients were included. Among the lung cancer patients, the uninsured patients had higher odds of having stage IV disease (odds ratio [OR] = 1.46; 95 % confidence interval [CI] = 1.22-1.76) and lower odds of receiving surgery (OR = 0.48; 95 % CI = 0.34-0.69) than the privately-insured patients. Among the colorectal cancer patients, uninsured status was associated with higher odds of stage IV disease (OR = 1.53; 95 % CI = 1.17-2.00) than privately-insured status. A significant insurance status and rurality interaction (p = 0.03) was found in the colorectal model for receipt of surgery. In the privately-insured group, non-Hispanic Black and rural patients had lower odds of receiving colorectal surgery (OR = 0.69; 95 % CI = 0.50-0.94 and OR = 0.68; 95 % CI = 0.52-0.89; respectively) than their non-Hispanic White and urban counterparts.

CONCLUSIONS

After controlling for confounding and evaluation of interactions between patient-, community-, and geographic-level factors, uninsured status remained the strongest driver of patients' presentation with late-stage lung and colorectal cancer. As policy and care delivery transformation targets uninsured and vulnerable populations, explicit recognition, and measurement of intersectionality should be considered.
