Unexpected high serum level of CA 125 in male patient suffering from metastatic papillary carcinoma: a case report
Abstract
This report describes a case of male patient with metastatic papillary carcinoma of unknown primary origin with unusual high levels of CA 125. Laboratory tests in serum and plasma (urea, creatinine, uric acid, sodium, potassium, total bilirubin, ALT, AST, GMT, ALP, C-reactive protein, and glucose) were normal except C-reactive protein (57.6 mg/l).
Computer tomography scan showed tumorous formations situated in the area of both kidneys. According to the literature we performed more detailed laboratory investigation (CEA, CA 125, CA 15-3, CA 19-9, AFP) and we found only serum level of CA 125 significantly elevated (> 600 kU/l).
The results of recent studies suggest that CA 125 might be useful as a serum tumor marker also in patients with other carcinomas apart ovarian cancer.
