[Cellular adhesion molecule (CD44) in ovarian tumors]
Objective:
To investigate a method of detecting adhesion molecule (CD44) contents in ovarian tumors and its clinical significance.
Methods:
In 106 patients with ovarian tumors (50 benign and 56 malignant), the adhesion molecule (CD44) contents in peripheral blood lymphocytes (PBL) and in neoplastic tissues were analysed (quantitatively by using flow cytometric-immunological method).
Result:
(1) The CD44 contents in the PBL of the patients with malignant tumor were obviously higher than those of patients with benign tumors (P<0.05) and than those of the control (P < 0.01); (2) Within the group of patients with malignant tumors, the CD44 contents in the neoplastic tissues were higher than those in the PBL (0.01 < P < 0.05); There was no significant difference in CD44 contents among the different histopathological types, whether benign or malignant; (4) The CD44 contents in the PBL decreased gradually after surgery.
Conclusion:
To analyse the CD44 contents in PBL and neoplastic tissues by flow cytometry may be an important method or parameter to differentiate benign ovarian tumors from malignant tumors and to discover recurrence of metastasis of malignant tumors in early stage.
