Local and Peripheral Immune Responsive Landscape Induced by Local Cryoablation in Patients With Lung Adenocarcinoma

NCT ID: NCT06104709

Last Updated: 2023-10-27

Basic Information

• Recruitment Status: UNKNOWN
• Total Enrollment: 10 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2023-12-01
• Study Completion Date: 2024-12-31

Brief Summary

The goal of this observational study is to learn about local and peripheral immune and metabolic changes in patients with lung adenocarcinoma undergoing cryoablation. The main question it aims to answer are:

• local and peripheral immune changes in patients with lung adenocarcinoma undergoing cryoablation.
• local and peripheral metabolic changes in patients with lung adenocarcinoma undergoing cryoablation.

Peripheral blood, biopsy tissues of patients will be collected at the baseline and after cryoablation. Single-cell sequencing, single-cell immune bank, metabolomics and spatial metabolomics will be used to explore the local and peripheral immune changes and metabolites changes in patients with lung adenocarcinoma before and after cryoablation.

Eligibility Criteria

Inclusion Criteria

2. Patients are not suitable for thoracotomy due to serious lung or systemic disease.

3. Peripheral lung cancer involves pleura and chest wall, which cannot be completely removed by surgical resection.

4. There are indications for surgical resection, but the patient refuses surgery.

5. Single tumor, maximum diameter ≤5cm; Or the number of tumors ≤3, the maximum diameter ≤3cm.

7. Patients with an expected survival of more than three months.

8. Patients have not participated in other clinical validation within 3 months.

9. Subjects voluntarily sign informed consent.

Exclusion Criteria

2. Severe pulmonary fibrosis, especially drug-induced pulmonary fibrosis.

3. Patients with previous severe pulmonary dysfunction, pulmonary ventilation disorder, and multiple pulmonary bulla.

4. A history of immunodeficiency, including a positive HIV test (enzyme-linked immunoassay and Western spot assay).

5. Patients treated with chemotherapy, radiotherapy, interventional therapy, ablative therapy or surgery within 30 days before surgical treatment.
