腫瘤科醫(yī)學論文-18F2FDG PET2CT標準攝取值與NSCLC臨床病理因素的關(guān)系
［摘要］ 目的 探討非小細胞肺癌（NSCLC)病人18氟脫氧葡萄糖（18F2FDG)PET2CT標準攝取值（SUV)與臨床病理因素的關(guān)系。方法 對80例確診為NSCLC的病人治療前行18F2FDG PET2CT檢查，測得SUV最大值（SUVmax)，分析 SUVmax與原發(fā)腫瘤大小、臨床分期、病理學類型及細胞分化程度之間關(guān)系。結(jié)果 腫瘤直徑>3 cm組和≤3 cm組的SUVmax差異有統(tǒng)計學意義（t=4.17,P<0.05),不同臨床分期（Ⅰ期與Ⅲa期、Ⅲb～Ⅳ期)SUVmax差異有統(tǒng)計學意義(F=7.05，P<0.01)。SUVmax與原發(fā)腫瘤大小及臨床分期呈正相關(guān)（r=0.658，P<0.01；r=0.286,P<0.05)。結(jié)論 18F2FDG PET2CT的SUV值隨著腫瘤大小和病期的增加呈升高的趨勢，而與細胞分化程度和病理學類型無關(guān)。

［ABSTRACT］ Objective To investigate the correlation between standard uptake value (SUV) of 18F2FDG PET2CT and clinical factors of non2small cell lung cancer (NSCLC). Methods Eighty patients with confirmed NSCLC underwent whole2body 18F2FDG PET2CT scan before treatment. The maximal SUV (SUVmax) was obtained and its association with primary tumor size, clinical staging, pathological type, and cell differentiation of NSCLC was analyzed. Results The differences of SUVmax were significant between tumor sizes of >3 cm and ≤3 cm (t=4.17,P<0.05), and among different clinical stages (stageⅠand stages Ⅲa and Ⅲb-Ⅳ) (F=7.05,P<0.01). SUVmax showed a positive correlation with the size of primary tumor and clinical staging (r=0.658,P<0.01;r=0.286,P<0.05). Conclusion The SUV of 18F2FDG PET2CT tends to rise with the increase of tumor size and stage, but it has nothing to do with cell differentiation and the type of pathology of NSCLC.
