[Tumor markers and creatine kinase in the differential diagnosis of tubal pregnancy].

In the present study we tried to evaluate the cancer marker CA 19-9, CA 12-5, CA 15-3 as well as the enzyme creatine-kinase (CK) whether they are of any diagnostic value in cases of tubal pregnancies. 15 patients with laporoscopically verified tubal pregnancy were compared with 15 patients with normal intrauterine pregnancies of the same age. Except one case of elevated CK in a patient with tubal pregnancy all other values were within the normal range. We concluded, that tumor markers and CK are inefficient for preoperative differential diagnosis in cases of tubal pregnancies.
