Abstract:

Objective To investigate the role of an elevated D-dimer(DD) cut-off value for the prognosis of lung cancer. Methods The clinical and laboratory data of 153 patients with lung cancer were studied retrospectively. Carcinoembryonic antigen(CEA),cytokeratin-19 fragment(CYFRA21-1),lactate dehydrogenase(LDH),squamous cell carcinoma antigen(SCC-Ag) and DD were determined before chemotherapy or surgery,and the results were analyzed statistically. Results There was no statistical significance for overall survival rate between different sex,age,CEA,CYFRA21-1,LDH and DD(P>0.05). The overall survival rate in high DD(≥981 ng/mL) group was lower than that in normal DD(<981 ng/mL) group(P<0.05). Conclusions The elevated DD cut-off value to 981 ng/mL is beneficial to prognosis prediction in lung cancer.
