Abstract:

Objective To investigate the clinical value of the plasma D-dimer detection in patients with non-small cell lung cancer(NSCLC). Methods The plasma D-dimer levels of 47 NSCLC patients and 66 healthy subjects were detected by immuno-nephelometry. The relationships between plasma D-dimer level and the clinical stage, pathological type and lymph node metastasis of NSCLC patients were analyzed.The D-dimer levels of NSCLC patients before and after chemotherapy were compared. The relationship between the D-dimer and the efficacy of chemotherapy was analyzed. Results The levels of plasma D-dimer were significantly higher in NSCLC patients[0.96(0.63~1.35)mg/L] than in the healthy subjects[0.34(0.17~0.39)mg/L,P<0.01]. The levels of plasma D-dimer in different clinical stage groups and pathological type groups were statistically significant(P<0.05);and it had relationship with lymph node metastasis(r=0.609, P<0.05). After chemotherapy, the levels of D-dimer in effective groups(contain complete response group and partial response group)were significantly decreased(P<0.05). There were no significant changes in stability group(P>0.05)and significant higher in progress group(P<0.05). Conclusions The plasma D-dimer has clinical significance in the clinical stage, pathological type and lymph node metastasis in NSCLC patients, and can be used as an effective indicator to evaluate the efficacy of chemotherapy.
