The significance of serum lipid-bound sialic acid in bladder tumours.
Tumour markers with high sensitivity and specificity for bladder cancer are still lacking and several markers have been investigated up to now. Serum lipid-bound sialic acid (LSA) was claimed to be a tumour marker by some investigators and this study tried to assess the value of LSA as a tumour marker in patients with bladder cancer. The results obtained from 27 patients and 30 controls showed that serum LSA levels remained within the suggested normal limits of the method used but they were significantly higher than in the controls. The value of serum LSA is questionable as an initial tumour marker for bladder cancer, but variations from the basal level may indeed be helpful in monitoring the efficacy of the therapy and in detecting relapses during follow-ups.
