NCT04597346

Brief Summary

The study is designed as a multicenter prospective trial of BTPNA for the diagnosis of peripheral pulmonary lesions in the real world. The purpose of the study is to evaluate the safety and effectiveness of BTPNA and to explore the factors of diagnosis rate.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic yield

    Diagnostic yield is defined as the proportion of lesions diagnosed by BTPNA in all lesions undergoing bronchoscopy biopsy by BTPNA.

    Six months

Secondary Outcomes (8)

  • The success rate of navigation

    Immediately after bronchoscopic biopsy

  • The success rate of biopsy

    Immediately after bronchoscopic biopsy

  • The operation time of the bronchoscope

    Immediately after bronchoscopic biopsy

  • The total time of lesion access

    Immediately after bronchoscopic biopsy

  • The intraoperative fluoroscopy time

    Immediately after bronchoscopic biopsy

  • +3 more secondary outcomes

Interventions

Bronchoscopic Transparenchymal Nodule Access (BTPNA) is locating the lesion in the lung tissue guided by the bronchoscope navigation system (LungPro) in the natural lumen (bronchus), and automatically calculates the best point of entry (POE) and the best route to avoid blood vessels. An opening is made from the POE under the endoscope, and is extended with a balloon dilator. Combined with X-ray fluoroscopy, a sheath with a blunt-tip core is used in the lung parenchyma to reach the lesion site, and then biopsy diagnosis or treatment.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Newly diagnosed patients whose chest CT showed suspect malignant peripheral lung lesion and are scheduled to receive non-surgical biopsies with lesion access via BTPNA.

You may qualify if:

  • Patients older than 18 years old.
  • Newly diagnosed patients whose chest CT shows peripheral pulmonary lesions that have bronchus signs but are difficult to reach through the intrabronchial path, or are adjacent to the airway, or have no bronchus sign, and are suspected of malignancy which need non-surgical biopsies.
  • The diameter of the lesions is greater than or equal to 0.8cm and less than 5cm
  • The location of lesions results in the following situations where transthoracic needle aspiration (TTNA) is difficult to obtain a diagnosis or the operation is relatively risky, or have not been diagnosed by TTNA and other non-surgical biopsies in the past.
  • Lesions can be accessed by BTPNA technology in preoperative assessment.
  • Understand the research and sign the informed consent form.

You may not qualify if:

  • Contraindications for bronchoscopy.
  • The lesions are adjacent to the target trachea or bronchus of points of entry(POE).
  • Severe cardiopulmonary dysfunction and other diseases that may significantly increase the risk of surgery.
  • Routine bronchoscopy showed visible lesions in the lumen.
