概述

When cancer starts in one place in your body and spreads to another, it’s calledmetastasis。When lung cancer metastasizes to the brain, it means the primary lung cancer has created a secondary cancer in the brain.

关于 20 to 40 percent 非小细胞的成年人肺癌go on to develop brain metastases at some point during their illness. The most frequent metastatic sites are:

  • 肾上腺
  • brain and nervous system
  • bones
  • 肝
  • 其他肺或呼吸系统

有两种不同种类的肺癌：

Lung cancers most typically spread to other parts of the body through the lymph vessels and blood vessels.

虽然肺癌更容易通过淋巴管传播，但通常需要更长的时间才能延长次要转移性癌。有了血管，癌症通常很难进入。但是，一旦这样做，它将相对较快地传播。

一般而言，短期内通过血细胞的转移较差，从长远来看，通过淋巴细胞的转移较差。

如果您被诊断出患有肺癌, it’s especially important to pay attention to symptoms of brain metastasis, including:

If you have any of these symptoms, report them to your doctor immediately.

To screen for metastatic brain cancer, doctors commonly use radiology tests such as:

Occasionally, a doctor may take a biopsy to determine if there’s脑癌礼物。

While sex, ethnicity, and age can affect survival, the life expectancy after a diagnosis of brain metastases from lung cancer is generally poor. Without treatment, the average survival rate is under 6 months 。With treatment, that number can increase slightly.

通常，那些与诊断更远的脑转移的人的存活率比肺癌更早地转移到大脑的人的存活率略高。但是，差异通常很小。

When it comes to treatment of lung cancer brain metastases, the available options depend on several different factors, such as:

  • the type of primary cancer that was diagnosed
  • the number, size, and location of脑部肿瘤
  • 癌细胞的遗传行为
  • 年龄和健康
  • 其他尝试的治疗

Treatment for metastatic brain cancer is dependent on the original type of lung cancer. When lung cancer spreads to the brain, it’s still considered lung cancer, not brain cancer.

脑转移治疗的主要类型是：

手术

手术可能是防御脑转移的第一道：

  • 肿瘤不多
  • 该疾病受到控制
  • 你身体健康

Whole brain radiation

Your doctor may recommend whole brain radiation if there are several tumors present. It can also follow surgery in some cases.

立体定向放射外科手术

这个治疗is a high-dose radiation therapy that targets a specific part of the brain and is usually used in patients with fewer tumors.

免疫疗法和targeted therapies

较新的治疗方法，例如immunotherapyand targeted therapies that can cross the blood-brain barrier, may be recommended as complementary treatment options.

In the late stage of lung cancer that’s spread to brain, the most frequent complications include:

During the final states, palliative care professionals try to optimize quality of life with psychological, technological, medical, and sociological considerations.

肺癌是 leading cause 全球男性和女性的癌症死亡。如果肺癌已经扩散到大脑，预后可能令人不安。

如果您或您认识的人患有肺癌，那么对脑转移症状的了解和警惕很重要。如果您注意到这些症状，请与您的医生交谈，并讨论可以提供舒适或增加生活质量和生存机会的治疗选择。
