Study summary

To verify the clinical effectiveness and safety of the airway tree navigation system constructed by artificial intelligence (AI) in the navigation diagnosis of peripheral pulmonary nodules (PPLs).

Read the detailed description

Early diagnosis and treatment of lung cancer is of great significance, in which navigated tracheoscopic biopsy is an important tool for confirming the diagnosis of early lung cancer. Conventional navigation software realizes airway reconstruction and guides biopsy by recognizing differences in HU values on computed tomography scans. It is difficult for conventional navigation software to recognize the reconstruction due to the special characteristics of small airways that are susceptible to interference and collapse. Therefore, an AI deep learning approach can realize accurate construction of small airways and guide accurate biopsy. This study intends to validate the clinical effectiveness and safety of the AI-constructed airway tree navigation system in the navigational diagnosis of peripheral pulmonary nodules (PPLs).

Inclusion criteria

  1. Aged 18 years or above.
  2. Patients with one or more peripheral lung nodules suspected to be lung cancer or poorly absorbing lesions on conventional anti-infective therapy.
  3. Patients with nodule diameters ≤30 mm (diameters mentioned in the text are the average of the maximum and minimum diameters).
  4. The nodules were pure ground glass nodules, partially solid nodules, or solid nodules.
  5. The nodule is surrounded by lung parenchyma and is not visible in the bronchial lumen above the segment.

Exclusion criteria

Exclusion Criteria:

  1. Preoperative judgment that it is difficult for the patient to benefit from bronchoscopic biopsy (e.g., high risk of bleeding due to perivascular encasement of the lesion, difficulty in reaching the airway adjacent to the lesion due to previous lung surgery, etc.).
  2. Those with incomplete clinical data.
  3. Those with missing visits after biopsy.

Study arms

  • Experimental
    New navigation system group

    The new AI-constructed airway tree navigation system (SARS-pro) was used for preoperative navigation path planning. The SARS-pro navigation system was independently developed by the research group based on a conventional augmented reality optical navigation system (LungPro; Bronchus Company).

    Diagnostic Test: Preoperative navigation path planning using the SARS-pro navigation system

  • Active comparator
    Old navigation system group

    Preoperative navigation path planning was performed using the old VBN system (LungPro; Bronchus Company).

    Diagnostic Test: Preoperative navigation path planning using the VBN navigation system

Interventions

  • Diagnostic testPreoperative navigation path planning using the SARS-pro navigation system

    The SARS-pro navigation system was used for preoperative navigation path planning for tracheoscopic biopsies in the new navigation system group (patients with suspected lung cancer).

  • Diagnostic testPreoperative navigation path planning using the VBN navigation system

    The VBN navigation system was used for preoperative navigation path planning for tracheoscopic biopsies in the old navigation system group (patients with suspected lung cancer).

What researchers measure

Primary outcomes

  1. Diagnostic positive yield

    After biopsy by navigational bronchoscopy, the biopsy tissue was tested for lung cancer pathology. A positive diagnosis was defined when the pathology report was a neoplastic lesion (benign or malignant tumor). A positive diagnosis was also made if the pathology report was a granulomatous lesion (with tuberculosis or fungus). If the pathology was reported as an inflammatory cell infiltration or other non-specific inflammation in the lungs, the subject underwent another pathology biopsy after at least 3 months of follow-up to rule out false-positive results due to a change in the site of the lesion.

    Time frame: One month after the patients were enrolled

Secondary outcomes

  1. Adverse events

    Patients underwent a follow-up period of 3 days after navigational tracheoscopic biopsy, and subjects were followed for adverse events such as hemoptysis, pneumothorax, and mediastinal emphysema.

    Time frame: 3 days after navigational tracheoscopic biopsy
