Abstract

Objectives

Given the current—and increasing—pressure to limit expenditure on health care provision in many countries, a better understanding of the cost burden of colorectal cancer is needed. Cost-of-illness studies and reviews thereof can be a useful tool for analysing and critically evaluating the cost-related development of colorectal cancer, and they highlight important cost drivers.

Methods

A systematic review was conducted from 2002 to 2012 to identify cost-of-illness studies related to colorectal cancer, searching the Medline, PubMed, Science Direct, Cochrane Library and the York CRD databases.

Results

Among the 10 studies (from France, the US, Ireland and Taiwan) included in the review, 6 studies reported prevalence-based estimates and 4 studies focussed on incidence-based data. In the studies included in the review, long-term costs for colorectal cancer of up to $50,175 per patient (2008 values) were estimated. Most of the studies in the review showed that the initial and terminal phases of colorectal cancer care are the most expensive, with continuing treatment being the least costly phase. One study also highlighted that stage I CRC disease was the least costly and stage III the most costly of all 4 stages, due to the high cost impact of biological agents.

Conclusions

This review has highlighted a trend for rising costs associated with CRC, which is linked to the increasing use of targeted biological therapies. COI studies in colorectal cancer can identify specific components and areas of care that are especially costly, thereby focussing attention on more cost-effective approaches, which is especially relevant to the increased use of biological agents in the field of personalised medicine. COI studies are an important tool for further health economic evaluations of personalised medicine.

Appendix

Appendix

The following criteria were used for study inclusion.

Study methods are described in adequate detail:

  • The study population is clearly described

  • There is a well-defined research question, posed in an answerable form

  • The disease differentiation is clearly laid out for colorectal cancer

  • The viewpoints of the analysis are clearly stated

There is enough economic detail in the study:

  • All costs are measured appropriately, i.e. monetary values for disease-specific attributed costs

  • The chosen time horizon is appropriate for the inclusion of relevant costs and consequences

  • Estimates of indirect and direct aspects of costs for colorectal cancer are given

  • The differentiation of cost aspects is made appropriately and in physical units

  • The different cost components are described in sufficient detail

  • For long-term costs of colorectal cancer, the estimates are based on a period of a minimum of 5 years of care following the onset of disease

The following exclusion criteria were used:

  • Cost-of-illness studies referring to colon cancer alone (excluding rectal cancer)

  • Studies focusing on co-morbidities like diarrhoea-related diseases as a result of chemotherapy

  • Studies referring to costs of colorectal screening interventions only

  • Studies comparing cost-effectiveness among different treatments for colorectal cancer

  • Cost-of-illness studies focusing on just one disease stage of colorectal cancer

  • Reviews of existing economic studies relating to colorectal cancer

  • Studies not reported in English or German
