目的  探討血清瘦素水平與結(jié)直腸癌各種臨床病理改變的關(guān)系。方法  用雙抗體夾心ABC-ELISA法檢測30例無營養(yǎng)不良的結(jié)直腸癌患者（腫瘤組）和24例健康成年人（對照組）血清瘦素水平，分析結(jié)直腸癌不同臨床病理特征下血清瘦素水平的差異； 檢測腫瘤組患者的血清CEA及CA19-9水平，用RT-PCR方法測定腫瘤組腫瘤標本中K-ras、p53、腺瘤性結(jié)腸息肉?。ˋPC）基因及結(jié)直腸癌缺失基因（DCC)mRNA的表達水平。結(jié)果  腫瘤組血清瘦素水平〔（3.53±1.72） μg/L〕明顯高于對照組〔（2.27±1.01） μg/L〕，P＜0.05，且這種差異與性別無關(guān)。腫瘤組中不同腫瘤部位、不同TNM分期間的血清瘦素水平差異無統(tǒng)計學意義（P gt;0.05）； 但隨著腫瘤分化程度的降低，血清瘦素水平呈現(xiàn)下降趨勢，其中低分化者的血清瘦素水平明顯低于高分化者和中分化者（P＜0.05）。腫瘤學的相關(guān)性分析結(jié)果顯示，血清瘦素水平與結(jié)直腸癌患者的血清CEA和CA19-9水平，腫瘤組織的癌基因K-ras以及抑癌基因p53、APC和DCC的表達均無相關(guān)性（P gt;0.05）。結(jié)論  結(jié)直腸癌患者血清中的瘦素水平高于正常人； 腫瘤的分化程度影響了血清瘦素的表達，但結(jié)直腸癌的TNM分期、部位和血清腫瘤標志物的水平與血清瘦素水平無關(guān)，與結(jié)直腸癌發(fā)生、發(fā)展密切相關(guān)的各種基因的表達與血清瘦素水平也無關(guān)。
