説明
Inclusion Criteria:
- Age 18 years or older, any sex. Primary pulmonary nodule has been surgically resected, with residual multiple pulmonary nodules or a need for pulmonary nodule-related routine postoperative follow-up.
Planned routine postoperative follow-up at a participating center and able to provide a research blood sample together with routine blood draw when clinically available.
Able to understand the study and willing to provide written informed consent before research blood sample collection.
Exclusion Criteria:
- Investigator judges that the participant is unsuitable for additional small-volume blood collection, such as severe anemia, obvious coagulation abnormality, recent severe bleeding, or high risk of severe vasovagal reaction.
Acute severe infection, acute major organ dysfunction, or other condition that may substantially affect peripheral immune status and makes study participation unsuitable.
Current strong immunosuppressive therapy that may substantially affect peripheral immune status and cannot be adequately recorded or adjusted for in analysis.
Unable to complete informed consent or explicitly refuses use of research blood samples and related data for this study.
Any other condition that, in the investigator's judgment, makes participation inappropriate.

Change from baseline in percentage of peripheral blood CD8+ CD57+ T cells measured by CyTOF
時間枠:Baseline and routine follow-up blood collections through 24 months
|
CyTOF mass cytometry will measure percentages of CD4+ T cells, CD8+ T cells, B cells, NK cells, Naive/TCM/TEM/TEMRA subsets, CD57-positive cells, HLA-DR/CD38-positive cells, and PD-1/CTLA-4/TIM-3/TIGIT-positive cells.
The outcome is the change from baseline in each prespecified percentage or marker-positive frequency.
