Interpretive Data:
Elevated levels of human chorionic gonadotropin in spinal fluid
indicate the probable presence of central nervous system metastases or
recurrence of tumor in patients with germ cell tumors, including
patients with testicular cancer or choriocarcinoma.
Comments:
Cautions:
Slight elevations of human chorionic gonadotropin (hCG) in spinal fluid may occur in non neoplastic diseases.
Measurement of hCG in spinal fluid should not be relied upon exclusively to determine the presence of central nervous system metastases in patients with germ cell tumors.
Useful For:
Facilitating diagnosis of brain metastases of testicular cancer or extragonadal intracerebral germ cell tumors.
