Serum HGF in 14 patients evaluated at diagnosis, at the completion of chemotherapy, and during the follow-up.

(A) Twelve patients showing normal HGF values (mean ± SEM) after chemotherapy were in continuing complete remission at a median follow-up of 16 months (range, 8-52 months). On the contrary, 2 patients with high levels of HGF after chemotherapy, despite achievement of clinical remission, relapsed 3 (B) and 5 (C) months later. The shadowed area indicates HGF values (mean ± SD) in healthy individuals.
