Abstract:
Objective To explore the correlation between 18F-FLT SUVmax and intratumoral microvessel density (MVD) in NSCLC patients.Methods From January 2008 to December 2010,68 patients (48males and 20 females; age ranging from 36 to 84 years) with NSCLC underwent 18F-FLT PET/CT followed by surgery within two weeks.Tumor proliferation was evaluated in terms of Ki67 labeling index (LI) with SP.MVD was determined using anti-CD31 mAb (CD31-MVD),anti-CD34 mAb (CD34-MVD) and anti-CD105 mAb (CD105-MVD) for each resected tumor.Linear correlation analysis was used to analyze data.Results The mean values of CD31-MVD,CD34-MVD and CD105-MVD were 159.6,166.1,and 38.0 per view field,respectively.Tumor SUVmax was 4.1±2.9,and Ki67 LI was (37.0± 14.5) %,both of which had significantly correlations with CD105-MVD (r=0.550,0.633 ; both P<0.05),but there was no significant relationship between SUVmax and CD31-MVD,CD34-MVD (r=0.228,0.235; both P>0.05).Conclusion 18F-FLT PET/CT imaging has a positive relationship with CD105-MVD of NSCLC,and it could reflect the ability of tumor angiogenesis.
