ABSTRACT
ObjectiveTo observe the dynamic changes of blood perfusion and hypoxic status by CT perfusion imaging and hypoxia imaging in patients with non-small cell lung cancer (NSCLC) after treatment with recombinant human endostatin (RHES). MethodsA total 15 patients with NSCLC were randomly divided into treatment group (n = 10) and control group (n = 5). The patients in treatment group continuouly received the treatment with RHES (7.5 mg/m2) by intravenous infusion for ten days, and CT perfusion imaging and hypoxia imaging were performed at day 1, 5 and 10,respectively. The time window' was observed with the blood perfusion status and hypoxic changes.ResultsIn the treatment group, capillary permeability surface (PS) and tumor to normal tissue (T/N) were firstly decreased, and then increased. Their lowest points occurred at about the fifth day. PS showed statistical significance compared with the first day (q1.5 = 12.05, P<0.01 ) and no significance compared with the tenth day(q10.5 = 2.79, P=0.69), while T/N showed a significant difference between above time points (q1.5 = 73.81, q10.5 = 20.6, P = 0.00).Blood flow (BF) was firstly increased, and then decreased.Its highest point appeared at about the fifth day with statistical significance compared with the first and tenth day (q1.5 = 12.29, q10.5 = 10.48, P<0.01 ). All the PS,BF and T/N between the fifth day in treatment group and the control group showed statistically significance (all P < 0.01 ).Conclusions The time window of recombinant human endostatin improving blood perfusion and hypoxic status in non-small cell lung cancer is within about one week after administration.
