title: [Heterozygote beta-thalassemia and neoplastic pathology].
abstract: To evaluate the possible correlation between heterozygote beta thalassemia (BTE) and neoplastic disease, a 5-year personal experience of clinically followed patients at Comacchio Hospital Internal Medicine and Surgery divisions is presented. The hemoglobin A2 was assayed in all patients whose medial corpuscular volume was lower than 80 fl. 589 consecutive neoplastic patients were evaluated; of these 73 were BTE. In the BTE patients the prevalence of neoplastic disease was 12.39% higher than in healthy people (8.8%, chi 2 = 8.79 and p = 0.03). In thalassaemic carriers the titres of medial annual incidence to 10,000 for neoplastic diseases were proved to be ever higher (46.08 versus 31.49/10,000). The incidence of gastric cancer was found to be greater in BTE than in non-trait carrier population (13 in 63 patients, with a 20.63% prevalence, chi 2 = 9.52 and p = 0.02). A higher prevalence of thalassaemic carriers was observed among subjects with cancer in different organs: larynx, oesophagus, gallbladder and bile ducts, pancreas, breast and kidney, but these differences were not statistically significant. As for various sites of cancer: lung, liver, uterus and ovary, bladder, prostate, skin, lymphomas, leukaemias and gammopathies, no difference in BTE prevalence was found. We conclude that a greater predisposition to neoplastic disease can be present in BTE than in healthy population.
