In the present study, we investigated whether there is a change in serum total and lipid bound sialic acid levels of patients with benign and non-melanom malignant skin tumors and, evaluated whether the measurement of sialic acid levels may be useful clinically in distinguishing patients with benign skin tumors from those with non-melanom malignant skin tumors. In this study, 27 patients with malignant skin tumors ( 16 men, age 50.78 +/- 12.46 years), 39 patients with benign skin tumors ( 17 men, age 48.59 +/- 16.23 years) were included. Serum total and lipid bound sialic acid determination was performed by the thiobarbituric acid method described by Warren and, the resorsinol method described by Katopodis, respectively. Student's T test and Z test were used to analyze the results. The mean serum total and lipid bound sialic acid levels were found to be 63.01 +/- 11.89 mg/dl and 15.77 +/- 2.44 mg/dl, respectively in patients with benign skin tumors; and 65.95 +/- 7.30 mg/dl and 16.70 +/- 3.80 mg/dl, respectively in patients with non-melanom malignant skin tumors. Serum total sialic acid and lipid bound sialic acid of patients with benign skin tumors were not different from those of patients with non-melanom malignant skin tumors. The percentage of lipid bound sialic acid was found to be 25.3 in patients with non-melanom malignant skin tumors, 25 in patients with benign skin tumors. There was no significant difference between the value of lipid bound sialic acid percentage in these groups. Our finding that there is no significant difference between serum total and lipid-bound sialic acid levels of patients with non melanom malignant skin tumors which are not able to metastase and patients with benign skin tumors supports the studies reporting that sialic acids play an important role in metastases.trinfo:eu-repo/semantics/closedAccessTotal Sialic AcidLipid Bound Sialic AcidNon Melanom Malignant Skin TumorBenign Skin TumorCell-Surface SialylationN-Acetylneuraminic AcidClinical-SignificanceCancerMelanomaGlycoproteinMetastasisRecurrenceCarcinomaDiseasesArticle3211721N/AWOS:000254852500003
