About

All patients undergoing video-assisted thoracoscopic (VATS) resection of lung cancer will receive standard therapy including lobectomy or sub-lobar resection and mediastinal lymph node dissection. After completion of the standard of care, intraoperative ultrasound will be used to evaluate lymph node stations for the presence of any missed lymph nodes with particular focus on lymph nodes which may appear pathologic on ultrasound evaluation. Data will be reviewed for rates of pathologic upstaging, and sensitivity and specificity of ultrasound as an additional diagnostic tool in the operating room will be evaluated. It is hypothesized that Intra-operative thoracoscopic ultrasound following standard video-assisted thoracoscopic (VATS) dissection will increase the rate of pathologically staged in N2 nodes in non-small cell lung cancer patients undergoing definitive surgical resection.

Exclusion criteria

Patients with known brain metastases

Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. (Patients with HIV are not excluded from this study)

Ultrasound

Experimental group

Description:

Participants in this study have elected to have surgical resection of non-small cell lung cancer tumors as part of their standard of care. During that surgical procedure, participants will also receive laparoscopic intraoperative ultrasound to assess the thoracic wall lymph nodes as part of the experimental procedure. The ultrasound procedure will add about 15 minutes to the total surgical time. Because it is laparoscopic and utilizes non-ionizing radiation, the risk to the participant is minimal.

Treatment:

Device: Intraoperative ultrasound
