目的:本研究的目的是要确定是否非小细胞肺癌原发肿瘤的大小可预测脑转移的存在。
方法:我们回顾性的重新查看了,在过去的两年中,35例(男16
,女19例,年龄41-95岁,
平均年龄67.4yrs)经胸部CT扫描被诊断为晚期非小细胞肺癌,而他们的脑部CT扫描均呈阴性反应的病人的肺部肿块的大小。然后,我们比较了35例(男16
,女19例,年龄41-91岁,平均年龄65.7岁)
,在胸部CT扫描,也确诊为肺癌,但CT扫描大脑中显示脑转移的病人肺部肿块的大小。
结果:患者无脑转移的肺部肿块较小(平均为3.311
± 1.668厘米;百分之九十五信赖区间为2.738-3.884 ),比那些脑转移(平均4.866 ± 2.612厘米;百分之九十五信赖区间为3.969-5.763
)。分界点是3.9厘米(取决于ROC曲线分析) ,脑转移瘤的概率比是13.96( P < 0.0001 ) 。
结论:非小细胞肺癌脑转移瘤与肺部肿块大小有直接关联。
临床意义:非小细胞肺癌肺部肿块>=3.9厘米预测脑转移瘤的存在。

PURPOSE: The aim of our study was to determine whether the size
of
a primary NSCLC predicts the presence of brain metastases.
METHODS: We retrospectively reviewed the size of lung mass by
CT
scan of the chest in 35 patients (16 males, 19 females, age
range
41-95 yrs; mean age 67.4yrs) who were diagnosed with NSCLC
during
the past two years whose CT scans of the brain were negative
for
brain metastases. We then compared it with the size of the
lung mass
in CT scan of the chest in 35 patients (16 males,
19 females, age
range 41-91 yrs; mean age 65.7 Yrs) who were
also diagnosed with
NSCLC but had CT scans of the brain that
showed brain metastases.
RESULTS: The size of lung mass in patients without brain metastases
was smaller (mean 3.311±1.668cm; 95%CI= 2.738-3.884)
than in
those with brain metastases (mean 4.866±2.612cm;
95%CI=3.969-5.763).
At a cut-off of 3.9cm (determined by ROC
curve analysis), the odds
ratio of brain metastases was 13.96
(P<0.0001).
CONCLUSION: There is direct correlation between the size of
the
lung mass and brain metastases in NSCLC.
CLINICAL IMPLICATIONS: Lung mass size 3.9cm in NSCLC predicts
the presence of brain metastases.
