| 摘 要： | 小细胞肺癌具有易复发和转移的生物学特点，脑是小细胞肺癌肺外转移的好发部位。局限期小细胞肺癌患者行预防性脑照射(PCI)能够有效降低脑转移的发生率，延长总生存期。但是在PCI后仍有近1/3的患者发生脑转移。本文对PCI后脑转移的危险因素进行综述，目的在于判断何种局限期小细胞肺癌亚组患者能够从PCI中获益，从而为PCI的临...

| Abstract: | Small cell lung cancer (SCLC) has the biological characteristics of high recurrence and metastasis. The brain is the common site of SCLC extrapulmonary metastasis. Prophylactic cranial irradiation (PCI) can effectively reduce the incidence of brain metastasis and prolong the overall survival of patients with limited SCLC. Nevertheless, nearly one third of patients develop brain metastases after PCI. This article reviews the risk factors of brain metastasis after PCI, aiming to determine which subgroup of patients with limited SCLC can benefit from PCI and provide reference for the clinical application of PCI. |
