China-Japan Friendship Hospital530 enrolled

Overview

A prospective multicenter randomized controlled trial was conducted to evaluate the diagnostic efficacy and safety of NCLE-NB-Rebus-guided peripheral pulmonary nodule biopsy, and to compare the diagnostic efficacy and safety of biopsy forceps biopsy and needle aspiration biopsy in peripheral pulmonary nodule biopsy guided by nCLE-NB-rEBUS.

A prospective, multicenter, randomized controlled trial was conducted to evaluate the diagnostic efficacy and safety of nCLE-NB-rEBUS guided peripheral pulmonary nodule biopsy. Patients with peripheral pulmonary nodules suspected of lung cancer and pulmonary tuberculosis were enrolled to sign informed consent. Subjects were randomized to the nCLE-NB-rEBUS Group (Group A) or the NB-rEBUS Group (Group B) subgroup (1:1 ratio) according to the random number table, and subjects randomly assigned to Group A or Group B were again randomized to the biopsy forceps subgroup or biopsy needle subgroup by the random number table. The diagnostic efficacy and safety of the NCLE-NB-REbus group and the NB-rEBUS group were compared to evaluate whether nCLE could improve the diagnostic rate of NB-REbus-guided peripheral pulmonary nodule biopsy. The diagnostic efficacy and safety of using biopsy forceps and biopsy needle in peripheral pulmonary nodule biopsy guided by nCLE-NB-rEBUS were compared to determine the reasonable biopsy method.

Inclusion Criteria: * Patients with peripheral pulmonary nodules suspected of lung cancer by CT examination * Patients who intend to undergo a bronchoscopic lung biopsy to determine benign or malignant pulmonary nodules; * Age ≥18 years * Sign informed consent. Exclusion Criteria: * There is an uncorrectable coagulation disorder or anticoagulation therapy that cannot be stopped before surgery; * Tumors can be seen in the bronchus * Hemodynamic instability; * Refractory hypoxemia; * Patients with pregnant and lactating patients * Any illness or condition that interferes with the completion of the initial or subsequent assessment.

Outcomes

Primary Outcomes

Diagnostic rate of biopsy to obtain pathological diagnosis.

The biopsies obtained from the two groups were fixed in 10% formaldehyde and sent for pathological examination. The pathological diagnosis results were identified by two pathologists back to back, and the results were consistent, that is, confirmed. If the results are inconsistent, they will be identified by a third pathologist and finally determined by the three experts after discussion.

Time frame: 6 months

Secondary Outcomes

Occurrence of operation-related complications

7 days of follow-up data (including bleeding, infection, pain, fever, etc.). Patients who did not obtain a confirmed diagnosis were followed up to 6 months after surgery to evaluate their diagnosis.

Time frame: 6 months
