The effect of socioeconomic deprivation on presentation stage and long-term outcomes in patients undergoing colorectal cancer resection in Western Sydney

Reduction in the diagnostic interval after the introduction of cancer patient pathways for colorectal cancer in northern Sweden

OBJECTIVE

To compare the diagnostic interval for patients with colorectal cancer before and after the introduction of cancer patient pathways in northern Sweden.

DESIGN

A retrospective study comparing two cohorts (2012 and 2018) of patients diagnosed with colorectal cancer before and after the introduction of cancer patient pathways in 2016.

SETTING

Three counties in northern Sweden with large sparsely populated areas and some cities (637143 residents ∼5.1 residents/km2).

SUBJECTS

Patients were included from the Swedish Cancer Register. Electronic health records reviews were performed and linked to socioeconomic data from Statistics Sweden.

MAIN OUTCOME MEASURES

Differences in the diagnostic intervals, the patient intervals and the characteristics associated with the longest diagnostic intervals and investigations starting at the emergency department.

RESULTS

The two cohorts included 411 patients in 2012 and 445 patients in 2018. The median diagnostic interval was reduced from 47 days (IQI 18-99) to 29 days (IQI 9-74) (p < 0.001) after the introduction of cancer patient pathways in general. Though for the cases of cancer in the right-side (ascended) colon, the reduction of the diagnostic interval was not observed and it remained associated with investigations starting at the emergency department.

CONCLUSION

Our results indicate that cancer patient pathways contributed to an improvement in the diagnostic interval for patients with colorectal cancer in general, yet not for patients with cancer in the right-side colon.

IMPLICATION

In general, cancer patient pathways seem to reduce the diagnostic interval for colorectal cancer but it is not a sufficient solution for all colorectal cancer localisations.

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.
