Summary
Brief summary
The purpose of this study is to assess whether there is a role of non-anaemic iron deficiency in colorectal cancer.

Who is it for?

You may be eligible for this study if you are an adult who has been diagnosed with colorectal cancer, and are also scheduled to undergo surgery for colorectal cancer.

Study details

Participants will continue with their current cancer treatment plan, and answer questionnaires in regards to their health over a 3-month period following their surgery.

The results of certain blood tests will also be used. These blood tests are taken as part of routine care. You will not be required to have additional blood tests if you are participating in this study.

The results of participants with iron deficiency prior to their surgery will be compared to those without iron deficiency.

We hope that this study will show that iron replete patients have improved recovery after surgery for colorectal cancer, and enable more widespread research into the role of iron treatments prior to this sort of surgery.
