Study information

Scientific title

The role of faecal occult blood testing in risk stratification for GI malignancy in subjects with iron deficiency anaemia

Acronym

IDIOM (3)

Study hypothesis

Screening patients with iron deficiency anaemia by means of faecal occult blood testing can identify sub-groups at high risk of underlying gastro-intestinal malignancy, over and above the stratification provided by established clinical criteria.

Condition

Iron deficiency anaemia caused by gastrointestinal malignancy

Intervention

All patients in the study will have a qualitative immunochemical stool test for occult blood prior to gastro-intestinal investigation of the cause of their anaemia.

All patients will be followed up until they have completed investigation of their iron deficiency anaemia, as clinically indicated. The study will assess whether faecal occult blood (FOB) testing at presentation can predict the likelihood of underlying gastrointestinal pathology in subjects with iron deficiency anaemia (IDA) and, in particular, cancer.

Intervention type

Other

Primary outcome measure

The predictive value of immunochemical faecal blood testing for gastrointestinal malignancy

Secondary outcome measures

The predictive value of immunochemical faecal blood testing for:
1. Colorectal cancer
2. Any bleeding lesion
