Vanderbilt-Ingram Cancer Center
This is a multi-center clinical trial evaluating the effect of transbronchial mediastinal cryobiopsy for its ability to improve the likelihood of obtaining tissue sufficient for molecular analysis. Patients in outpatient clinics or pre-operative holding areas planning to undergo a bronchoscopic biopsy of a suspected malignant lesion (peripheral or mediastinal) for initial diagnosis, staging, or tissue acquisition for molecular analysis will be considered for enrollment and consented. Patients will only be enrolled if intraoperative ROSE suggests malignancy. Patients will be randomized to continue with the operator's initial EBUS-TBNA needle or switch to a cryoprobe to perform a sampling.
Primary Objective: \- To evaluate the utility of transbronchial mediastinal cryobiopsy on its ability to improve the likelihood of acquiring tissue sufficient for next-generation sequencing (NGS). Safety Endpoints: * Pneumothorax within 7 days of procedure * Moderate bleeding defined as controlled with bronchoscope, saline, or epinephrine * Serious bleeding is defined as uncontrolled, leading to respiratory failure, need for transfusion, or cardiovascular instability * Respiratory failure is defined as a new oxygen requirement or escalation in oxygen delivery within 7 days of procedure * Un…
Inclusion Criteria: * Lesions on PET or CT concerning for primary or metastatic malignancy that are amenable to biopsy by linear EBUS * Malignant cells present on rapid on-site cytological evaluation (ROSE) Exclusion Criteria: * Patient is known to be less than 18 years old * Patient is known to be pregnant * Patient is known to be a prisoner * Operator deems lesion is not safe to biopsy
