[Relation between blood coagulability and prognosis in patients with ovarian cancer]

In 13 patients with ovarian cancer who had been treated with remission induction chemotherapy, we measured the levels of platelet PT, APTT, Hepa T, ATIII, alpha 2PI and FDP, and we also measured such molecular markers as fibrinopeptide A(FPA), fibrinopeptide B beta 1-42(FPB beta 1-42), and fibrinopeptide B beta 15-42 (FPB beta 15-42) before and after chemotherapy. Then the relation between the post chemotherapeutic trends of these substances and the prognosis for patient with ovarian cancer were investigated. 1) After chemotherapy, the levels of fibrinogen were increased, ATIII was decreased significantly in cases in the NC.PD group compared with the PR.CR group (p less than 0.05). The alpha 2PI concentrations were also slightly low, and the levels of FDP were within the normal range in cases in the PR.CR group, but in many cases in the NC.PD group were increased. 2) After chemotherapy, the concentrations of molecular markers (FPA, FPB beta 1-42 and FPB beta 15-42) were increased significantly in cases in the NC.PD group compared with the PR.CR group (p less than 0.05). 3) In cases in the recurrent group, the levels of ATIII and alpha 2PI were decreased significantly compared with the after therapy group, FDP, FPB beta 1-42 and FPB beta 15-42 were increased. Accordingly, the recovery of hemostatic balance with effective chemotherapy is related to the prognosis for patients with ovarian cancer, and the levels of fibrinogen, PT, alpha 2PI, ATIII, FDP, FPA, FPB beta 1-42 and FPB beta 15-42 may be able to be used in the prognosis for patients after chemotherapy.
