MALIGNANCIES IN beta-THALASSEMIA PATIENTS: FIRST DESCRIPTION OF TWO CASES OF THYROID CANCER AND REVIEW OF THE LITERATURE

beta-Thalassemias are a group of hereditary blood disorders characterized by abnormalities in the synthesis of the beta hemoglobin (Hb) chains. This disease causes excessive storage of iron in all organs and endocrine glands. Treatment of beta-thalassemia major (beta-TM) consists of regular blood transfusions, iron chelation and management of secondary complications of iron overload. Endocrine abnormalities are frequently observed. In the last 25 years, the clinical picture of the disease has changed progressively thanks to improvement of treatments. Today, the majority of thalassemic patients reach adult age. The better prognosis and the longer lifespan of affected patients could be responsible for the susceptibility to other concomitant diseases which can manifest during their life. In this context, the possibility and recent literature reports about some cases of malignancy in thalassemic patients open new scenarios for oncoming years. We describe first reports of endocrine malignancies in thalassemic patients.
