Figure 1. Overall survival (OS) comparison among colon cancer patients with and without iron deficiency anemia (IDA).
Among adult male and postmenopausal female colon cancer patients, median OS times were 4.6 and 5.7 years for patients with per-existing IDA and those without per-existing IDA, respectively. Patients with pre-existing IDA had inferior OS compared to those without pre-existing IDA (p = 0.002).
