Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.

Objective To investigate the clinical significance and diagnostic value of plasma D-dimer measurement in response evaluation of female patients with tumor. Methods 149 female cancer patients were enrolled, in which there were 58 post-operative early staged cases(post-operative group), 91 metastatic cases(metastatic group). D-dimer levels before chemotherapy (D1) and after the last cycle of chemotherapy (D2) were assessed and analyzed to examine whether they are correlated to response of therapy. D-dimer levels were presented as median(25^th percentile,75^th percentile) and compared using Wilcoxon signed-rank test(for paired samples) and Mann-Whitney U test(for independent samples). Spearman rank tests were conducted to show the correlation of two variables. Results In post-operative group,D2 was lower than D1(ΔD=-184.8,P<0.0001),and both of D1 and D2 were positively correlated with age(r²= 0.356,0.389,respectively,P<0.01). In metastatic group, after chemotherapy,33 cases had progressive diseases(PD group), while 58 cases gained response or stable diseases(non-PD group). Baseline D-dimer level of PD group was higher than that of non-PD group(1586 vs 754.2,P<0.01),and after chemotherapy the case was similar(2511 vs 525.8,P<0.01). After chemotherapy, D-dimer level increased in PD group(ΔD=1124,P<0.0001), and decreased in non-PD group(ΔD=-153.3,P=0.0045).We compared the abilities of the ΔD(ΔD=D2-D1), D1and D2 to discriminate between responders and non-responders using receiver operating characteristic curves(ROC). The areas under the curve (AUC) of the ΔD, D1and D2, were 0.8603(95%CI:0.7685-0.9520)、0.6740(95%CI:0.5582-0.7597)、0.8956(95%CI:0.8291-0.9621), respectively. The appropriate cut-off values with biggest Youden index of D-dimer for non-responders were as follows: ΔD＜-145.4 ng/mL,D1>1375ng/mL,D2>1033ng/mL. Conclusion Plasma D-dimer level is strongly associated with tumor burden. D-dimer could be used to predict prognosis and treatment response in female patients with tumor.
