Inclusion criteria

✓. At least 18 years of age (including 18 years of age, male or female) and voluntarily signed informed consent;
✓. Chest CT imaging showed at least 2 pulmonary nodules with a diameter of less than 3cm in ipsilateral lung, and imaging diagnosis of highly suspicious multiple primary lung cancer
✓. No surgical contraindication, surgical resection is feasible, and postoperative pathology is diagnosed as multiple primary lung cancer according to Martini and Melamed criteria and gene testing
✓. The amount of at least 2 or more tissues removed from multiple pulmonary nodules must meet the requirements of pathological diagnosis, molecular detection and microflora detection

Exclusion criteria

✕. under 18 years of age (excluding 18 years of age, male or female) or unwilling to sign informed consent;
✕. severe heart, liver, brain, kidney and other important organ diseases and bone marrow hematopoietic dysfunction;
✕. Preoperative examination of patients who cannot tolerate surgical resection
✕. Patients who received antibiotics within 1 week before surgery E) Resected multiple pulmonary nodules with pathologically proven lung cancer of less than 2 patients
✕. Multiple nodules resected were confirmed to be metastases, not primary lung cancer

What they're measuring

Microbial homology between upper gastrointestinal (UGI) microbiota and intratumoral microbiota

Timeframe: Sequencing and analysis will be completed within 6 months after sample collection.
