Summary Fibrinopeptide A (FPA) was systematically investigated in 74 patients with acute leukaemia at different stages of the disease (50 with non-lymphocytic leukaemia, ANLL; 24 with lymphocytic leukaemia, ALL). At diagnosis, 75% of the cases had high FPA levels (86% in ANLL and 54% in ALL) with significantly higher levels in ANLL than in ALL (13.4 vs 4.4 ng/ml; p〈0.001). Patients with DIC (20 cases in ANLL and 1 case in ALL) had significantly higher levels (p〈0.001). FPA levels were neither correlated with fibrinogen or FDP levels nor with blast cell count. During chemotherapy, median FPA did not show significant changes whereas, at the end of therapy, a return toward normality was generally observed both in ALL and ANLL apart from the group of patients with acute promyelocytic leukaemia. Among the 24 patients who entered post-remission follow-up (13 ANLL and 11 ALL), 10 cases out of the 11 relapsing (6/6 with ANLL and 4/5 with ALL) had increased FPA 1 to 2 months before the ascertainment of the relapse. However, 16% and 9% of the samples obtained on different occasions, respectively from ANLL and ALL cases in maintained first remission, showed FPA above the normal limit. This study demonstrates that subclinical activation of blood coagulation, as indicated by high FPA level, is common both in lymphocytic and non-lymphocytic leukemia and suggests that this phenomenon is related to disease activity.
