Not Applicable

Completed

• Conditions: Quality of Tissue Obtained; Quantity of Tissue Obtained; Ease of Use of 22-gauge ProCore EBUS Needles and the Standard 22-gauge Needles
• Interventions: Other: 22-gauge ProCore Needle; Other: 22-gauge Standard Needle

• Registration Number: NCT02154698
• Lead Sponsor: Medical University of South Carolina

Brief Summary

The purpose of this study is to compare the usefulness of two needles (used for obtaining a lung tissue sample : (1) standard 22-gauge, and (2) ProCore 22-gauge) for endobronchial ultrasound

Detailed Description

The purpose of this study is to compare the usefulness of two needles used for obtaining a lung tissue sample: (1) standard 22-gauge, and (2) ProCore 22-gauge. Both of these needles are used to get biopsies (samples) of lung tissue. The standard needle has one bevel (angled side of the needle formed when it is sharpened to make a point), while the ProCore needle has 2 bevels. The standard needle is more commonly used and we are doing this study to see if the ProCore needle would be more useful.

The investigator in charge of this study is Dr. Nichole T. Tanner. This study is being done at four sites and will involve approximately 200 volunteers.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 200

Inclusion Criteria

1. Subjects with known or suspected lung cancer with mediastinal adenopathy as defined by a mediastinal lymph node >1 cm in short axis or a normal sized lymph node with uptake on FDG-PET scan that is higher than background PET activity.
2. Participants must be at least 18 years old or older, lack bleeding disorders, and be able to provide informed consent. The latter two criteria will be assessed from the patient's history and the consenting interview.

Exclusion Criteria

1. Subjects who refuse to participate, or demonstrate inability to give informed consent
2. Subjects who are less than 18 years of age
3. Subjects who lack fitness for flexible bronchoscopy as determined by the physician performing the bronchoscopy before the procedure
4. Subjects with suspected sarcoidosis, lymphoma, or metastatic cancer from other sites (i.e. those without a known or suspected lung primary)
5. Subjects on anticoagulation (other than Aspirin) whom cannot have their anticoagulation held for the procedure due to other clinical reasons (i.e. recent cardiac stent placement).

Arm && Interventions

Group	Intervention	Description
22-gauge ProCore Needle	22-gauge ProCore Needle	Participants will have each node sampled starting with the ProCore 22G on the first pass followed by the standard 22G needle on the second pass (for a total of 8 passes)
22-gauge Standard Needle	22-gauge Standard Needle	Participants will have each node sampled starting with the standard 22G needle on the first pass followed by the ProCore 22G needle on the second pass (for a total of 8 passes)
