ABSTRACT
Context We previously reported a novel tumour associated antigen (TTA) with molecular weight around 48 kDa and identified the novel TTA as a fragment derived from human DNA-topoiomerase I (TOP1). We termed the novel TAA as TOPO48 and termed autoantibody against the TAA as anti-TOPO48 autoantibody.Objective:
To explore the clinical significance of anti-TOPO48 autoantibody in patients with colorectal carcinoma (CRC).Materials andmethods:
Serum levels of the autoantibody in patients with CRC or benign tumours and healthy volunteers were measured with a specific ELISA.Results:
CRC patients at early stage had higher frequency of positive levels of the autoantibody and CRC patients with positive autoantibody levels had higher overall survival rate than those with negative autoantibody levels.Conclusion:
The autoantibody is a potential biomarker for early diagnosis and favourable prognosis of CRC.Palavras-chave
