Abstract:
Objective To investigate the predictive value of the plasma D-dimer levels on stage and response to chemotherapy of the pancreatic cancer (PC).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 212 PC patients who were admitted to the Fudan University Shanghai Cancer Center between December 2016 and May 2017 were collected.Plasma D-dimer levels of 212 patients were measured,and relationship between plasma D-dimer levels and clinicopathological features or response to chemotherapy were analyzed.Observation indicators:(1) relationship between clinicopathological features and positive rate of plasma D-dimer before treatment;(2) relationship between response to chemotherapy and plasma D-dimer levels;(3) follow-up and survival situations.Follow-up using telephone interview was performed to detect survival of patients up to January 2018.Comparisons of count data were analyzed using chi-square test.Measurement data with skewed distribution were described as M (range).Results (1) Relationship between clinicopathological features and positive rate of plasma D-dimer before treatment:positive rate of plasma D-dimer before treatment was respectively 18.37％ (9/49),43.64％ (24/55),53.85％ (28/52),80.36％ (45/56) in patients with stage Ⅰ-Ⅱ A,ⅡB,Ⅲ and Ⅳ of TNM staging and 43.59％(17/39),24.62％(16/65) in patients with low-differentiated tumor and high-and moderate-differentiated tumor,with statistically significantly differences (x2 =41.454,4.051,P＜0.05).(2) Relationship between response to chemotherapy and plasma D-dimer levels:of 212 PC patients,108 received pathological diagnosis by endoscopic ultrasonography or liver puncture,and then underwent 4-6 cycles chemotherapy with gemcitabine.Of 108 patients,response to chemotherapy of 59 patients was partial remission or stable disease,plasma D-dimer level before treatment was increased in 39 patients (28 with reduced plasma D-dimer level after treatment) and normal in 20 patients;response to chemotherapy of 49 patients was progressive disease,plasma D-dimer level before treatment was increased in 34 patients (8 with reduced plasma D-dimer level after treatment) and normal in 15 patients.There was no statistically significant difference in proportion of patients with increased plasma D-dimer level before treatment (x2=0.132,P＞0.05),and there was a statistically significant difference in proportion of patients with reduced plasma D-dimer level after treatment (x2 =16.929,P＜0.05).(3) Follow-up and survival situations:212 patients were followed up for 3.5-12.0 months,with a median time of 7.5 months.During the follow-up,7 patients died and 205 had survival.Conclusion The plasma D-dimer level is significantly associated with TNM staging of the PC,tumor differentiation and response to chemotherapy.
