Overview
Brief Summary
The goal of this clinical trial is to verify the safety and clinical benefit of pulsed electric field(PEF) treatment of metastatic non-small cell lung cancer(NSCLC) patients with acquired resistance to anti programmed cell death protein 1(PD-1) monoclonal antibody therapy.
The main questions it aims to answer are:
- Safety of PEF treatment of metastatic NSCLC patients.
- Control of ablated and other targeted lesions.
- Local and peripheral immunoregulation effect. PEF energy will be delivered to preselected lesions of participants, then anti PD-1 will be routinely administrated if no adverse event(AE)/serious adverse event(SAE) which need medical intervention occurs.
Detailed Description
Eligible patients will will be enrolled to experimental arm and receive standard of care combining with PEF treatment on Day 1, followed by anti PD-1 on Day 7 and then routinely. All kinds of adverse events will be recorded and analyzed to evaluate the safety of the treatment. At the same time, the local control rate of treated lesions, PFS and OS after PEF will be analyzed to evaluate the clinical value of the treatment.

Eligibility Criteria
Inclusion Criteria
- •Patients over 22 years old with pathologically confirmed non-small cell lung cancer stage III-IV.

- •Lesions to be ablated must be ≤ 3cm in longest diameter(LD).
- •\* The leison to be ablated can be ≤ 5cm in LD, if evaluated as possible with multiple energy delivery in a single session.
- •More than one measurable lesion according to RECIST 1.1 except PEF targeted lesions.
- •Eastern Cooperative Oncology Group(ECOG) performance status 0-1
- •Life expectancy ≥3 months
