Brief Summary

With the advent of CT screening for lung cancer, an increasing number of NSCLCs are being detected at very early stages, and the demand for pulmonary segmentectomy is rising rapidly. As such, there is a need to develop new surgical techniques to facilitate minimally invasive pulmonary segmentectomy, as segmentectomy may provide a number of significant advantages over lobectomy for patients presenting with early-stage lung cancer, or for patients unable to undergo a full lobectomy due to existing comorbidities. This study will provide the first case series using preoperative 3D anatomical planning (Synapse 3D) added to ICG and NIF-guided robotic segmentectomy to date and will be the first reported use of Synapse 3D-guided targeted pulmonary segmental resection in Canada. As lung cancer is the most frequently fatal cancer in North America, many thousands of patients will be able to benefit from this operation every year.

Outcome Measures

Primary Outcomes (2)

Study Arms (1)

Synapse 3D Lung Modelling + IC-GREEN Segmentectomy

EXPERIMENTAL

Patients within this arm will undergo a high-resolution CT scan of the chest, which is required by Synapse 3D to create accurate 3D virtual model reconstructions. At the start of the operation, the 3D virtual model of the segmental pulmonary anatomy will be displayed on the da Vinci Robotic platform for operative planning. The model will be used as a guide to determine which vessels are involved in the segment and need to be removed. The surgeon will ligate the pulmonary vein and pulmonary artery of the broncho-pulmonary segment with the lung cancer nodule, isolating it from any blood supply, and mark the proposed segmental planes based on the 3D model. ICG will be prepared as a sterile solution (2.5 mg/10mL) for injection. After vascular ligation, an 8 mL bolus of ICG solution will be injected into the peripheral vein catheter, followed by a 10 mL saline solution bolus

Device: Synapse 3D Lung ModellingDrug: IC-Green (ICG)

Interventions

The 3D virtual models provided by Synapse 3D will be made by experts in medical image analysis using the high-resolution CT scans. Patients will have 3D virtual reconstructions of their pulmonary anatomy with the target lesion created pre-operatively.

Synapse 3D Lung Modelling + IC-GREEN Segmentectomy

ICG will be prepared as a sterile solution (2.5 mg/10mL) for injection. After vascular ligation, a 6 to 8mL bolus of ICG solution will be injected into the peripheral vein catheter, followed by a 10mL saline solution bolus. The Firefly camera will then be used for the NIF imaging. It is expected that the entire lung, except the segment which was previously isolated from blood supply, will fluoresce within 30-40 seconds, exhibiting a green hue. The surgeon will perform the pulmonary resection and the resected 'dark' lung segment will be immediately evaluated by a pathologist, depending on the pathologist findings the operation may be concluded or the patient will receive a pulmonary lobectomy.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Tumour size \<3 cm
  • Clinical Stage 1 Non-Small Cell Lung Cancer (NSCLC)
  • CT-imaging confirming that the tumour is confined to one broncho-pulmonary segment, rendering the patient a candidate for segmental resection.

You may not qualify if:

  • Hypersensitivity or allergy to ICG, sodium iodide, or iodine
  • Women who are currently pregnant or breastfeeding; or women of childbearing potential who are not currently taking adequate birth control.
  • Patients with clinical evidence of N1 or N2 disease on preoperative imaging
  • Pulmonary Function tests demonstrating Forced Expiratory Volume in 1s (FEV1) or diffusion capacity of the lung for carbon monoxide (DLCO) less than or equal to 30% of predicted.
