Only limited data on the prevalence of iron deficiency (ID) and its correlation with clinical parameters are available in cancer. ID frequently contributes to the pathogenesis of anemia in patients with cancer and may lead to several symptoms such as impaired physical function, weakness and fatigue.Parameters of iron status and clinical parameters were evaluated in 1528 patients with cancer who presented consecutively within a four-month period at our center. One thousand fifty-three patients had solid tumors and 475 hematological malignancies.ID [transferrin saturation (TSAT) < 20%] was noted in 645 (42.6%) of the 1513 patients with TSAT tests available and 500 (33.0%) were anemic. ID rates were highest in pancreatic (63.2%), colorectal (51.9%) and lung cancers (50.7%). Of the 409 iron-deficient patients in whom serum ferritin levels were available additionally to TSAT, 335 (81.9%) presented with functional ID (FID) (TSAT < 20%, serum ferritin ≥30 ng/ml) and 74 (18.1%) with absolute ID. In patients with solid tumors, prevalence of ID correlated with cancer stage at diagnosis (P= 0.001), disease status (P = 0.001) and ECOG performance status (P = 0.005).ID was frequently noted in cancer and was associated with advanced disease, close proximity to cancer therapy, and poor performance status in patients with solid tumors.
