Serum tumor markers for detection of bone metastasis in breast cancer patients.

For the diagnosis of bone metastasis in breast cancer patients during systemic treatment serum tumor markers, including carbohydrate antigens 15-3 (CA 15-3) and 19-9 (CA 19-9), cancer antigen 125 (CA 125), alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), beta-2 microglobulin (BMG), ferritin, and tissue polypeptide antigen (determined by the M3 monoclonal antibody, TPS) were measured in 22 patients with known bone metastases and in 30 patients without documented metastases. The most useful single marker was CA 15-3. By stepwise discriminant analysis, it was found that 90% of the patients could be diagnosed truly by using the markers CA 15-3, BMG and ferritin. It is concluded that monitoring with combinations of tumor markers at regular intervals increases the diagnostic efficiency.

[Value of neuraminic acid as a clinical parameter in 42 patients with small-cell bronchial cancer].

The serum concentrations of neuraminic acid, CEA, gamma-Gt, 5-nucleotidase, haptoglobin, and alkaline phosphatase were determined before therapy and three and six months after the initiation of therapy in 42 patients with small cell bronchial carcinomas. Before therapy, a significantly increased serum concentration as compared to normal values was found for neuraminic acid in 97% of patients (43/44), for CEA in 54.7% (23/42), for gamma-Gt in 19% (8/42), for 5-nucleotidase in 11.9% (5/42), for haptoglobin in 36.3% (14/44), and for alkaline phosphatase in 9.5% of all patients (4/42). Three and six months later, these laboratory investigations did not give any valuable hint with respect to therapy results, with the exception of neuraminic acid (p less than 0.05). Prior to therapy, the concentrations of neuraminic acid were considerably increased in patients (mean = 3.16 +/- 0.47 mumol/ml) with regard to normal values (mean = 1.90 +/- 0.14 mumol/ml). Within the total group of 42 patients suffering from small cell bronchial carcinomas, there was no significant difference between the serum concentrations of neuraminic acid of eleven patients with localized tumors (mean = 3.12 +/- 0.53) and those of 31 advanced tumor patients (mean = 3.16 +/- 0.45) (p less than 0.05). During the six months' treatment period, the concentration of neuraminic acid was valuable as clinical parameter in 36 patients, i.e. 85% of all cases (0.001 less than p less than 0.01). It was shown that the serum concentration of neuraminic acid indicated a regression of the disease in 23 patients (p less than 0.001), a progression in 8 patients (0.02 less than p less than 0.05), and a regression with subsequent progression of the tumor in 5 patients (0.001 less than p less than 0.01).

Haptoglobin and transferrin types in Eti-Turks.

Haptoglobin and transferrin types were examined in Eti-Turks. The Hp1 frequency was 0.26. With the exception of two individuals with transferrin D, only the transferrin C was observed. The gene frequencies were in the range of most of the Asiatic populations including Turks.

Osteoarticular pains and changes in Wilson's disease: a radiological study in fourteen patients in nine Turkish families.

A series of 14 patients with Wilson's disease were evaluated in order to determine the characteristic bone changes found in this metabolic disorder. The following radiologic and clinical findings deserve to be summarized: (1) Osteoarticular pains as first manifestations of Wilson's disease were found in six patients. (2) In all but 2 of our patients, minor or moderate or even severe bone abnormalities characteristic for Wilson's disease were observed. (3) There were three groups of sibs. Among these sibs, the lesions were not only similar in type but were also acquired approximately at the same time, showing the influence of the different genes responsible for this metabolic disorder.
