Abstract:
Objective To investigate the change ofpermeability surfaces (PS) of CTperfusion(CT-p) before chemotherapy and early period treatment with chemotherapy (the first cycle of chemotherapy) in advanced non-small cell lung cancer and explore the correlation with the efficacy of chemotherapy.Methods Eighty patients with advanced non-small cell lung cancer which confirmed by pathology were taken standardized treatment by first-line drug.All patients performed with the CT-p technique before chemotherapy and one cycle after chemotherapy.The efficacy was evaluated by RECIST after 4 cycles of chemotherapy,the patients were divided into complete remission (CR) + partial response (PR),stable (SD),development (PD) according to the results and the change of PS was compared among these groups before chemotherapy and after 1 cycle of chemotherapy.Results Seventy-four patients' values of PS were useful.The remission rate and the stability rate was 32.4％ (24/74) and 78.4％ (58/74) respectively after 4 cycles of chemotherapy.PS after 1 cycle of chemotherapy in CR +PR (24 cases) and SD (34 cases) was lower than that before chemotherapy (12.38 ± 1.86 vs.18.13 ± 2.45,13.24 ± 1.97 vs.17.93 ± 2.38),and there was significant difference (P ＜0.05).There was no obvious change in PS before chemotherapy and after 1 cycle of chemotherapy in PD (16 cases),and there was no significant difference(P＞ 0.05).Conclusions The value of PS which reflects the change of perfusion in tumor vessel at early chemotherapy and the prognosis of the non-small cell lung cancer.Use the change of PS to predict the prognosis of patients with chemotherapy.It could be the norm of calculating the curative effect of chemotherapy in non-small cell lung cancer.
