Abstract
Limited studies have been performed to associate abnormal phospholipid (PL) profile and disease activity in hematological malignancies, including non-Hodgkin lymphoma (NHL). The aim of his study was to evaluate the levels of plasma PL fractions in NHL patients, in response to chemotherapy. Forty non-treated patients with NHL and 25 healthy individuals were recruited. Blood samples from patients were taken before chemotherapy, after 3 cycles and after the end of the treatment, and PL fractions were resolved by one-dimensional thin-layer chromatography. To assess potential relationship between plasma PL profile and response to therapy, patients were divided according to clinical outcome in 3 groups: complete remission (CR), stable disease (SD) and progression (PG). Despite significant differences between NHL patients and healthy controls, no differences were found at baseline among patients divided according to clinical outcome. During and after chemotherapy important alterations in PL profile were observed. Levels of total PLs and all PL fractions decreased in patients with PG while in patients who responded to therapy (CR, SD) PLs significantly increased. Results of our study suggest that changes of total PLs and PL fractions during the therapy are associated with the effects of therapy and clinical outcome in patients with NHL.
