[A peculiar form of anemia in patients operated on for cancer of the oral cavity].
The authors related about a peculiar form of anemia found in some patients operated on oral cancer; these patients had an almost normal hematic situation before their operation. 63 patients, operated in the course of a year for oral cancer, have been studied by the authors; they have found in 14 cases (22.2%) a light anemia which regressed after a self blood transfusion, during the first week after the operation; in other 8 cases (12.7%) the anemia, which was more serious, persisted beyond the 7th day after the operation. Those 8 patients, suffering from more serious and persistent anemia, were treated from 7th to 21st day after the operation with iron, vitamin B12 and folic acid without any improvement. The hematic situation improved about 10 days after the end of treatment, probably as a result of spontaneous renewal of medullar haemopoietic activity. This anemia, is characterized by normochromia, normocytosis, reduced response of reticulocytes, sideropenia and hyperferritinaemia. The authors think that the pathogenesis of anemia after operation in neoplastic patients is caused by medullary insufficiency existing before the operation, connected with reduced erythropoietin production and emphasized by an operation that sometimes cause bleeding. Consequently the authors hypothesis the use of erythropoietin in the therapy of most severe anemia in neoplastic operated patients.
