Safety of Lung Cryobiopsy in People With Cancer

Safety of Transbronchial Cryobiopsy in a Cancer Population

Source: ClinicalTrials.gov · Last updated 1 Jul 2026

Brief summary (registry, in English)

The purpose of this study is to find out whether a biopsy technique called transbronchial cryobiopsy (TBCB) is a safe alternative to the standard biopsy procedure (transbronchial forceps biopsy; TBFB). The study researchers think that TBCB may provide better biopsy samples to help diagnose lung disease.

Prior treatment

  • Antiplatelet therapy that cannot be held for more than 5 days.

Other illness

  • Known pulmonary hypertension or echocardiographic pulmonary artery systolic pressure \>50mmHg

Lab values

  • Uncorrectable coagulopathy defined as:
    • Platelet count \<50,000 x 10\^9/L or
    • prothrombin time international normalized ratio \>1.5

Other

  • Patients with pulse oximetry less than 92% on oxygen delivery up to 2 L nasal cannula.
  • A secure diagnosis based on clinical and high-resolution CT scan data.
  • Any patient deemed unfit to undergo bronchoscopy by the proceduralist
  • Female patients with a positive pregnancy test within 30 days of the planned study procedure

Who the study is looking for

  • 18 years of age or greater
  • Patients with known or suspected diagnosis of cancer and indeterminant pulmonary nodules or diffuse parenchymal lung disease with non-diagnostic clinical profiles for whom a lung biopsy is deemed useful for diagnosis.
