[Application of multi-tumor markers in ovarian carcinoma]

To improve the specificity and sensitivity of diagnosis and to strengthen postoperative monitoring for patients with ovarian cancer.

Sera obtained from patients-ovarian epithelial carcinoma (67 cases), benign ovarian tumor (33 cases) and from donor (38 cases) as control. Serologic examination of 5 tumor markers--SA, LSA, CA125, CP2, and 6B11Ab2 was performed.

The sensitivity and specificity in diagnosis of ovarian cancer were 83.6% and 85.9% respectively for CA125 alone (> 35 kU/L) whereas 86.6% and 94.4% respectively for multi-tumor markers combined in which 3 or more indices showed positive. In addition, serial measurements of multi-tumor markers have been done for 1 year after operation in 24 cases of ovarian epithelial carcinoma. The correlations between the levels of multi-tumor markers either and the results of second look operation or and clinical manifestation of recurrence were analyzed.

Multi-tumor markers examination could improve the diagnosis of ovarian cancer and early detection of recurrence.
