ObjectiveTo prospectively investigate whether any of the perfusion parameters would predict early tumor response to chemotherapy and/or radiotherapy and prognosis in non-small cell lung cancer (NSCLC). MethodsIn a prospective series, Perfusion CT were performed in 152 patients suspected lung cancer with 16-slice or 8-slice multislice CT. Contrast medium (50 ml) was injected at a rate of 4 ml/s with a power injector.The scanning delay was 10 seconds and the scanning time was 50 seconds.Among 152 patients,123 patients were proved lung cancer by pathology.With the perfusion 3.0 software, the parameters including blood flow (BF), blood volume (BV), mean transit time (MTT) and capillary permeability surface area product (PS) were calculated. The perfusion image quality was evaluated on a 4-1eveal scale. The treatment response after chemotherapy and(or) radiotherapy was assessed with Response Evaluation Criteria in Solid Tumors (RECIST) ,and then the relationship between perfusion parameters with early tumor response to chemotherapy and(or) radiotherapy was evaluated. Student t test and Kaplan-Meier estimates were used for data analysis. ResultsIn 84 patients (68.3%), the perfusion image quality was staged level 2 (moderate) and level 3 (good). Among them, 35 patients with NSCLC were assessed with RECIST after chemotherapy and (or) radiotherapy.In these 35 patients, The BF of responders and nonresponders was (81.0±33.6)and (56.3±23.1) ml·min~(-1)·100 g~(-1),respectively, which was significantly different(t=2.393, P=0.023). The median PFS of low-BF group (BF≤80 ml·min~(-1)· 100 g~(-1)) and high-BF group (BF>80 ml·min~(-1)·100 g~(-1)) was 11.8 and 8.0 months respectively (P>0.05), and the median PFS of low-BV group (BF≤6 ml/100 g~(-1)) and high-BV group (BF>6 ml/100 g~(-1)) was 9.2 and 8.0 months respectively(P>0.05), both of them were not significantly different.ConclusionNSCLC in high perfusion are relatively sensitive to chemotherapy and/or radiotherapy, and the response rate is relatively higher, but the progress time is relatively shorter.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.
