title: Clinical value of protein-bound fucose in patients with carcinoma and other diseases.
abstract: Protein-bound fucose content in sera from normal persons and patients with various malignant and non-malignant diseases was measured and statistically analyzed. Normal serum gave a mean value of 6.84 +/- 0.13 mg/100 ml, and rarely exceeded 9 mg/100 ml. Although no significant difference was found between sexes, there was a tendency of fucose content to decrease in older persons. It was noted that more than 90% of cancer-bearing patients have significantly higher level than critical value (9 mg/100 ml), while only 8.7% of patients with benign tumor showed positive result. These results were not limited to special organs but in common to all cases studied. The elevation of serum fucose content in malignant tumor was well correlated with its stages of progression, though the levels were less significant in early and in rather locally restricted breast and thyroid cancer. Serial postoperative follow-up study showed that the levels in serum fucose content was a useful parameter for judging the effectiveness of therapy and the prognosis of the patient. The fucose content in malignant tumor tissue and metastasized lymph node appeared to be significantly elevated than that in normal tissue. The practical usage and limitation of the fucose value in various diseases, together with a possible source of serum fucose were discussed.
