【摘要】：目的：探讨孤立性肺结节空间分布特征及伴随恶性征象二者间的关系。方法：收集188例孤立性肺结节，根据结节所处位置与支气管的关系，由肺门向胸膜侧将肺野分为内侧带、中间带及外侧带；然后再由肺尖向肺底，依据肺叶分布区域分为上野、中野及下野；最后再将所有结节伴随的恶性征象与分布区域进行相应的统计分析。结果：在188例孤立性肺结节中，位于内侧带、中间带、外侧带的结节数，分别为7例、57例、124例，相应具有恶性征象的结节数分别为1例、34例、107例，经过数据分析软件进行数据统计及分析得到总体2=29.75，组间2值分别为5.18,16.10和23.73，P值均＜0.05，总体及组间均存在明显差异性；而位于上野、中野、下野的结节数，依次为84例、18例、86例，相应具有的恶性征象的结节数分别为69例、10例、63例，经过统计分析得到总体2=6.11，P＜0.05，而组间2值分别为6.00，2.23和1.93，，后两组P＞0.05，组间不存在差异性。结论：孤立性肺结节所具有的恶性征象与分布区域在横向空间具有差异性，在纵向空间不具有差异性。
[Abstract]:Objective: to investigate the spatial distribution of solitary pulmonary nodules and the relationship between them. Methods: 188 cases of solitary pulmonary nodules were collected and divided into medial zone, intermediate zone and lateral zone from hilar to pleural side according to the relationship between the location of the nodules and the bronchi, and then from the tip of the lung to the lung bottom, and then to the upper field according to the distribution region of the lobes. Finally, the malignant signs and distribution of all the nodules were statistically analyzed. Results: in 188 solitary pulmonary nodules, the number of nodules located in medial zone, intermediate zone and lateral zone was 124 cases in 57 cases and 107 cases in 34 cases with malignant signs, respectively. The data statistics and analysis of data analysis software showed that the total value was 20.75, the values of 2 were 5.180.10 and 23.73 P < 0.05, respectively, and there were significant differences between the two groups, while the number of nodules in the upper, middle and lower fields were 84 cases, 18 cases and 86 cases, respectively, and there were significant differences between the two groups in the number of nodules in the upper field, the middle field and the lower field, respectively, in which 86 cases were found in the upper field, middle field and lower field. The number of malignant nodules in 69 cases and 10 cases were 63 cases respectively. Statistical analysis showed that the total number of malignant nodules was 26.11 (P < 0.05), while the value of 2 was 6.002.23 and 1.93 between the two groups respectively, and there was no difference between the two groups (P > 0.05). Conclusion: the malignant signs and distribution of solitary pulmonary nodules are different in transverse space and not in longitudinal space.
