 (submitted: October 9, 2018)
Detection of Occult Pathologic N2 Lymph Nodes [ Time Frame: At time of surgery ]
Participants undergoing resection of lung tumors will have laparoscopic thoracic wall ultrasound in an attempt to identify pathologic N2 lymph nodes. Data will be presented as the ratio of lymph nodes identified as cancerous to the total number of lymph nodes investigated with the ultrasound technique.

Descriptive Information
Brief Title  ICMJE Thoracoscopic Lung Cancer Staging With the Use of Intraoperative Ultrasound
Official Title  ICMJE A Single-arm, Phase II Study of Thoracoscopic Lung Cancer Staging With the Use of Intraoperative Ultrasound at the Time of Definitive Resection
Brief Summary 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.

Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Lung Cancer
Intervention  ICMJE Device: Intraoperative ultrasound
Intraoperative ultrasound will be performed at the completion of the standard lung cancer resection with mediastinal lymph node dissection. This evaluation will be performed by a different surgeon from the primary surgeon performing the operation to minimize operator variability with the ultrasound system and help control for bias. Additional lymph nodes identified will be resected and sent for pathologic evaluation. It is anticipated that this additional evaluation and treatment should take no more than 30 minutes and as such a time limit of 30 minutes from introduction of the ultrasound probe into the surgical field will be set.
Other Name: B-K Medical/Analogic 8666-Radio Frequency laparoscopic ultrasound transducer and the bedside flex Focus 1202 imaging system
Study Arms  ICMJE Experimental: Ultrasound
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.
Intervention: Device: Intraoperative ultrasound
