Brief Summary
The goal of this observational study is to learn about the survival benefit of local therapy combination with target therapy in lung cancer brain metastases with EGFR mutation. The main questions it aims to answer are:
- Is local therapy performed before or after target therapy would provide survival benefit ?
- What kind of local therapy combining with target therapy would provide survival benefit, neurosurgical resection or radiotherapy?

Outcome Measures
Primary Outcomes (1)
OS
Overall survival
From date of first follow-up until the date of documented death from any cause, assessed up to 120 months
Secondary Outcomes (1)
PFS
From date of first follow-up until the date of first documented progression, assessed up to 120 months
Study Arms (2)
target therapy + local therapy group vs target therapy alone group
local therapy before target therapy group vs local therapy after target therapy group
Interventions
Participants who underwent target therapy and surgery or radiotherapy were divided into target therapy + local therapy group. Participants who underwent target therapy alone were divided into target therapy alone group
Participants who underwent surgery or radiotherapy before target therapy were divided into local therapy before target therapy group. Participants who underwent surgery or radiotherapy after target therapy were divided into local therapy after target therapy group.
Eligibility Criteria
Hospital clients from Sun Yat-sen University Cancer Center, Guangxi Medical University Cancer Hospital, The People's Hospital Of Guangxi Zhuang Autonomous Region, and the First Affiliated Hospital of Guangxi Medical University will be selected.
You may qualify if:
- Evidence of pathological diagnosis of primary tumor.
- Brain metastases confirmed by enhanced magnetic resonance imaging.
- Gene test indicated that EGFR mutation.
- Complete clinical information.
You may not qualify if:
- If surgical treatment is accepted, the surgical treatment is not tumor resection, but ventricle puncture, biopsy and other non-tumor reducing surgery.
- Patients with 2 or more types of tumors.
- Incomplete clinical information.
