title: [Neuraminic acid (NANA) in the serum as an indicator in breast cancer].
abstract: The serum concentration of neuraminic acid and the carcino-embryonic antigen (CEA) were measured in 178 patients with diagnosed mammary carcinoma and 114 control patients. Among these 178 patients, 16 showed a local recurrence, 68 were tumor-free, and 94 had distant metastases. Only 42 out of these 94 patients kept the check-up appointments. During six months, they were regularly examined and treated with cytostatic drugs. The neuraminic acid levels corresponded mostly to the clinical state and the response to chemotherapy of these patients. All of the 94 patients with generalized mammary carcinoma had a significantly increased neuraminic acid concentration in the serum (p less than 0.001). The serum levels were not modified in 16 patients with local recurrences and in 68 tumor-free patients. The CEA values did not correspond to the serum neuraminic acid levels and the clinical state of the patients. The increase of the neuraminic acid concentration in the serum of these 42 patients with metastatic mammary carcinomas show that this parameter is a valuable indicator for the progression of this disease.
