Spots Global Cancer Trial Database for CLI and FAR for Intraoperative Margin Assessment

Study Description

Brief Summary: This study is a prospective, single arm interventional study to evaluate the diagnostic accuracy of intraoperative Cerenkov luminescence imaging (CLI) plus flexible autoradiography (FAR) using the LightPath® Imaging System for intraoperative tumour margin assessment compared to post-operative standard-of-care histopathology in women undergoing breast-conserving surgery for breast cancer.

Detailed Description: The intraoperative LightPath images will be used to inform the operating surgeon about potentially detectable cancer at the margins of the excised specimen in an attempt to achieve better guided cancer surgery and complete tumour excision with clear resection margins. If a positive excision margin is detected on intraoperative LightPath® images, the operating surgeon will take a cavity shaving of the corresponding margin, provided more tissue can be taken. Subsequent LightPath® imaging of the cavity shaving will inform the operating surgeon on the margin status of the shaving. If a positive excision margin is detected on intraoperative LightPath® images, the operating surgeon will take a further cavity shave of the corresponding margin, provided more tissue can be taken. The resection margin status of the WLE specimen and cavity shavings (if any), as assessed by LightPath CLI + FAR imaging will be compared with final histopathology results. A positive margin on histology will be defined as * Invasive carcinoma: positive: \<1mm; negative ≥1mm * Ductal carcinoma in situ (DCIS) (if present): positive: \<2mm; negative ≥2mm.
