作者的目的在於明確非小細胞肺癌(NSCLC)患者在確定接受手術前是否應該先進行腦部核磁共振(MR)檢查。回顧性分析結果顯示,在646例NSCLC患者中,6.3%發生腫瘤腦轉移,且大多發生在術後1年。腺瘤亞型和確診時已處於早期的NSCLC患者更容易發生轉移。據估算,使用術前MRI檢查,通過評估體積倍增時間,術前MR成像能夠發現大多數(71%)的腫瘤腦部轉移。

作者認為,所有NSCLC患者均應該行術前MRI檢查,以確定是否發生腦轉移。
TAKE-HOME MESSAGE
The authors of this paper aimed to establish whetherpreoperative brain imaging with magnetic resonance (MR) should be performedprior to definitive surgery for NSCLC. They retrospectively found that, in 646patients, 6.3% developed brain metastases postoperatively and that most ofthese occurred within 1 year of surgery. Patients with an adenocarcinomasubtype and those who were considered early stage at the time of diagnosis weremore likely to develop metastasis. It was estimated using volume doubling timesthat most of the brain metastases (71%) could have been detected withpreoperative MR imaging.
