Participants who had clinical symptoms of central nervous system metastases (such as brain edema, require hormonal intervention, or progress of brain metastases).

Imaging (CT or MRI) showed that the tumor invades or demarcates large blood vessels. 6. Imaging (CT or MRI) showed obvious hollow or necrotic tumors in the lungs; those with marginal adenocarcinoma with cavities can be considered after discussion with the clinician. 7. Participants who had high blood pressure and cannot be well controlled with antihypertensive medication (systolic blood pressure ≥140mmHg or diastolic blood pressure ≥90 mmHg). 8. Participants who had poorly controlled clinical symptoms or diseases of the heart, such as: (1) heart failure above NYHA 2 (2) unstable angina pectoris (3) myocardial infarction within 1 year (4) clinically significant supraventricular Sexual arrhythmias require treatment or intervention. 9.
