[Blood fibronectin changes in various neoplasms].
In 85 patients presenting with various cancers, changes in the frequencies of plasma fibronectin and of the carcino-embryonic antigen (CEA) were compared and the results were correlated with the degree of extension. Forty-six percent of patients with mammary adenocarcinoma had plasma fibronectin values higher than the age-related limit range, but only 18% had an increase in CEA. In patients with secondary metastases, the highest values were significantly different from those found in controls. In these cases, fibronectin was present in abnormal concentrations in more than 80% of the patients, and CEA in 50%. Positive fibronectin values were less frequent in other cancers, except those of the genital tract. Neither fibronectin nor CEA are organ-specific, yet these two tumoral markers differ in the frequency with which they appear, notably in patients with mammary carcinoma.
