Официальное название

Cryobiopsy-centered Versus Forceps Biopsy-centered Sampling for the Diagnosis of Peripheral Pulmonary Lesions - a Multicenter Prospective Randomized Controlled Trial

Обзор

This multicenter clinical trial evaluates the diagnostic yields of cryobiopsy and forceps biopsy for peripheral lung nodules. In the cryobiopsy group, cryobiopsy is the primary method, supplemented by forceps biopsy. Conversely, in the forceps biopsy group, forceps biopsy is the primary method, supplemented by cryobiopsy. The study also explores the complementary relationship between the two methods and examines differences in diagnostic rates based on the order in which the procedures are performed.

Подробное описание

This is a multi center, clinical trial evaluating the diagnostic yields of cryobiopsy and forceps biopsy methods used for the biopsy of peripheral lung nodules. In the cryobiopsy group, cryobiopsy is the primary method, with forceps biopsy used as an auxiliary technique, while in the forceps biopsy group, forceps biopsy is the primary method, with cryobiopsy as the auxiliary technique. The study also investigates the complementary relationship between these biopsy methods and evaluates differences in diagnostic rates based on the sequence of the procedures.

Вмешательства

  • Диагностический тест Transbronchial lung biopsy with radial probe endobronchial ultrasound (Cryobiopsy centered)
    When the lung nodule is visualized by bronchoscope using RP-EBUS, cryobiopsy is performed, followed by forceps biopsy.
  • Диагностический тест Transbronchial lung biopsy with radial probe endobronchial ultrasound (Forceps biopsy centered)
    When the lung nodule is visualized by bronchoscope using RP-EBUS, forceps biopsy is performed, followed by cryobiopsy.

Критерии участия

Критерии включения

  • Age ≥ 18 years
  • Obtained written informed consent
  • Subjects having <30mm nodule on computed tomography
  • Subjects without contraindication to brochoscopy

Критерии исключения

  • Patients with central lesions that can be visually confirmed by bronchoscopy or those with suspicious findings of cancer metastasis in the mediastinal lymph nodes, who do not require radial bronchial endoscopic ultrasound (RP-EBUS).
  • Patients who cannot discontinue medications that increase bleeding risk, such as antiplatelet agents or anticoagulants.
  • Patients with bleeding disorders (e.g., platelet count < 100,000/mm³).
  • Patients with severe comorbidities (e.g., serious respiratory or cardiovascular diseases) that make bronchoscopy unsafe.
  • Patients with hypersensitivity or allergies to drugs commonly used in endoscopic procedures, including lidocaine, midazolam, fentanyl, or flumazenil.
  • Pregnant or breastfeeding patients.
  • Patients with confirmed lung cancer undergoing rebiopsy for genetic testing or other purposes.

Критерии приведены из реестра в оригинале (на английском). Окончательную оценку соответствия проводит исследовательский центр.
