BackgroundDuring minimally invasive pulmonary resection, both limited visualization and tactile feedback can make localization of pulmonary nodules and assessment for synchronous disease challenging. Intraoperative molecular imaging is an emerging technology that can enhance a surgeon’s ability to detect cancers at the time of resection.Case presentationIn this report, we describe the application of a folate receptor-targeted, near infrared optical contrast agent (OTL38) for the detection of an invasive pulmonary adenocarcinoma. During molecular imaging, an otherwise undetectable synchronous nodule was also identified. This finding resulted in intraoperative upstaging and operative plan modifications.ConclusionThis report marks the first successful utilization of a targeted, near infrared intraoperative molecular imaging probe useful for thoracic malignancies. This rapidly evolving technology may enhance the surgeon’s ability to perform a number of oncologic procedures including tumor localization, margin assessment and intraoperative staging.
