【摘要】：目的探討肺浸潤性腺癌的能譜CT碘基物質(zhì)分析與Ki-67表達程度的相關性。方法回顧性分析經(jīng)病理證實的44例肺浸潤性腺癌患者資料,所有患者的免疫組織化學指標均包括Ki-67,并且于術前行能譜CT增強掃描,包括動脈期及靜脈期,分別延遲25 s、55 s。根據(jù)CT縱隔窗上腫瘤含實性成分的多少,分成實性結(jié)節(jié)組(18例)、m GGN組(19例)、p GGN組(7例)。采用Spearman相關法分析所有病例中Ki-67與動脈期及靜脈期腫瘤平均碘基值的相關性,及與腫瘤實性成分多少的相關性;分別分析實性結(jié)節(jié)組、m GGN組、p GGN組中Ki-67與動脈期及靜脈期腫瘤平均碘基值的相關性。結(jié)果所有病例中,Ki-67與動脈期及靜脈期腫瘤平均碘基值均呈負相關性(P0.05)。另外,Ki-67與肺癌結(jié)節(jié)中實性成分呈正相關(P=0.02,r=0.36)。實性結(jié)節(jié)組和m GGN組中,Ki-67與動脈期及靜脈期腫瘤平均碘基值均呈負相關性(P0.05)。p GGN組中,Ki-67與動脈期及靜脈期腫瘤平均碘基值均無相關性(P0.05)。Ki-67分組中動脈期及靜脈期平均碘基值均有明顯差異性(P0.05)。結(jié)論肺浸潤性腺癌的碘基值與Ki-67具有較好的負相關性,在評估腫瘤增殖能力上可以對Ki-67進行補充。
[Abstract]:Objective to investigate the correlation between the expression of Ki-67 and the level of Ki-67 expression in invasive lung adenocarcinoma. Methods 44 cases of lung invasive adenocarcinoma confirmed by pathology were retrospectively analyzed. Ki-67 was included in all patients, and enhanced EDS CT scan was performed before operation, including arterial phase and venous phase, with a delay of 25 s or 55 s. According to the solid composition of the tumor in the mediastinal window of CT, A total of 18 cases of solid nodules were divided into two groups: GGN group (n = 19) and GGN group (n = 7). Spearman correlation method was used to analyze the correlation between Ki-67 and the mean iodine base value of arterial and venous tumors, and the correlation between Ki-67 and tumor solid composition. The correlation between Ki-67 and the mean iodine base value of arterial and venous phase tumors in solid GGN group was analyzed respectively. Results in all cases, Ki-67 was negatively correlated with the mean iodine base value in arterial phase and venous phase. In addition, Ki-67 had a negative correlation with the mean iodine base value in arterial phase and venous phase. There was a positive correlation between Ki-67 and the mean iodine base value in arterial and venous phase in solid nodule group and m GGN group. There was no significant difference between Ki-67 value and average iodine base value in arterial phase and venous phase in P0.05 + p GGN group. There were significant differences in the average iodine base values in arterial and venous phases in P0.05. Ki-67 groups. Conclusion there is a good negative correlation between iodine base value and Ki-67 in pulmonary infiltrating adenocarcinoma. Ki-67 may be supplemented in evaluating tumor proliferation.
