PRETREATMENT PLASMA-LEVELS OF FIBRINOPEPTIDE-A (FPA), D-DIMER (DD), AND VON-WILLEBRAND FACTOR (VWF) IN PATIENTS WITH OPERABLE CERVICAL-CANCER - INFLUENCE OF SURGICAL PATHOLOGICAL STAGE, TUMOR SIZE, HISTOLOGIC TYPE, AND LYMPH-NODE STATUS

The preoperative plasma levels of fibrinopeptide A (FPA), D-dimer (DD), and von Willebrand Factor (vWF) were measured in 38 patients with cervical cancer undergoing radical hysterectomy with pelvic lymphadenectomy. The surgical-pathological stage of disease was Ib in 17 patients, IIa in 9 patients, and IIb in 12 patients. The tumor size was ≤4 cm in 20 patients and >4 cm in 18 patients. The histologic type was squamous cell carcinoma in 32 patients and adenocarcinoma in 6 patients. Positive pelvic lymph nodes were found in 10 patients. When compared to controls, FPA, DD, and vWF levels were significantly raised in patients with surgical-pathological stage IIb disease but not in patients with stage Ib or IIa disease. The values of FPA, DD, and vWF were related to surgical-pathological stage (stage IIb vs stage Ib-IIa: P < 0.005, P < 0.001, and P < 0.001, respectively) and tumor size (>4 cm vs ≤4 ≤cm: P < 0.05, P < 0.005, and P < 0.02, respectively), but not to histologic type. vWF values were also related to lymph node status (positive vs negative lymph nodes: P < 0.02). FPA and DD levels were higher in patients with positive lymph nodes than in patients with negative lymph nodes, but the difference did not reach the statistical significance even due to the small number of patients involved. In conclusion, increased fibrin production and degradation seem to occur in patients with stage IIb cervical cancer. The biological meaning of this hemostasis activation deserves further investigation. © 1993 Academic Press. All rights reserved.
