Brief Summary
This prospective phase II study is determined to explore the efficacy and safety of radiotherapy and bevacizumab maintenance therapy for oligometastatic lung adenocarcinoma with negative driver genes
Detailed Description
This prospective phase II study is determined to explore the efficacy and safety of radiotherapy and bevacizumab maintenance therapy for oligometastatic lung adenocarcinoma with negative driver genes. The patients receive SBRT radiotherapy for the primary (if any) and metastatic lesions or divided radiotherapy with or without concurrent chemotherapy.Bevacizumab maintenance therapy starts 1-2 months later after the chemotherapy.The recommended dose for intravenous infusion is 15mg/kg body weight, and the drug is given every 3 weeks until disease progression or intolerable toxicity occurs. Toxicities will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v. 4.0.

Eligibility Criteria
Inclusion Criteria
- •Pathological confirmation of lung adenocarcinoma with negative driver gene including EGFR and ALK.
- •Simultaneous oligometastasis, or oligometastasis which occurs after treatment of stage i-iii lung adenocarcinoma (1-5 metastases)
- •Oligometasis confirmed by CT, brain MR, bone ECT or PETCT within 30 days before enrollment.
Exclusion Criteria
- •≥18 years old
- •Eastern Cooperative Oncology Group (ECOG) performance status 0-
- •Organ and bone marrow functions are normal within the first 30 days of enrollment, including: • AST, ALT≤ 2.5\*ULN or ≤5\*ULN (with liver metastasis); • TBil ≤ 1.5 ULN • neutrophils absolute value ≥500 cells/mm3 • creatinine clearance ≥45 mL/min ;• platelets≥50,000 cells/mm
- •Negative pregnancy test 1 week before enrollment for women of childbearing age.
- •Patients with concurrent oligostasis should have received at least 4 courses of first-line chemotherapy, and SD or PR should be evaluated after chemotherapy;
- •Patients with stage i-iii lung adenocarcinoma with oligo-metastasis after treatment who have previously received systemic chemotherapy (such as concurrent radiotherapy chemotherapy or postoperative adjuvant chemotherapy) are admitted to the group;
- •Patients who have received brain radiation therapy due to brain metastasis are admitted to the group.
- •The baseline is the exsiting of measurable lesions, and the metastatic lesions are treated with local radiotherapy;The number of metastases defines as:
- •- A) two metastatic lesions are identified when bilateral adrenal glands have lesions;
- •- B) two consecutive vertebral lesions and paravertebral lesions within 6cm can be considered as one metastatic lesion, and the lesions of non-continuous vertebral body should be counted separately;
