In patients with head and neck cancer (HNC), surgical removal of cancerous tissue presents the best overall survival rate. However, failure to obtain negative margins during resection has remained a steady concern over the past 3 decades. The need for improved tumor removal and margin assessment presents an ongoing concern for the field. While near-infrared agents have long been used in imaging, investigation of these agents for use in HNC imaging has dramatically expanded in the past decade. Targeted tracers for use in primary and metastatic lymph node detection are of particular interest, with panitumumab-IRDye800 as a major candidate in current studies. This review aims to provide an overview of intraoperative near-infrared fluorescence-guided surgery techniques used in the clinical detection of malignant tissue and sentinel lymph nodes in HNC, highlighting current applications, limitations, and future directions for use of this technology within the field.

Background: The liver cone unit (Tokyo 2020 terminology) of the peripheral portal vein territory represents the smallest anatomical and functional unit of the liver. While this unit enables anatomical, subsegmental resection, particularly in patients with cirrhosis, the tumor-bearing cone unit can be challenging to identify intraoperatively. PATIENTS AND METHODS: A 58-year-old man with hepatitis C-related cirrhosis (Child-Pugh B) was diagnosed with a subcapsular hepatocellular carcinoma (HCC) in segment 8.

Fluorescence-guided surgery enhances surgical precision by enabling real-time tumor visualization. Here, we developed a cathepsin B-activatable imaging probe conjugated to the EGFR-targeting antibody cetuximab (Cetux-CB probe) for fluorescence-guided resection of triple-negative breast cancer (TNBC). The probe consists of a cathepsin B-sensitive peptide linker, a near-infrared fluorophore (Flamma™ Fluors 749), and a quencher (qFlamma Black01), enabling enzymatic activation following tumor-specific accumulation.

Brain tumors are one of the most dangerous cancers with serious effects on human health. The primary treatment approach involves a combination of surgery, supplemented by postoperative radiotherapy. The growth pattern of malignant tumor is typically infiltrative, posing a challenge in visually distinguishing the tumor from the surrounding normal brain tissue during surgery.

Image-guided surgery plays a critical role in improving the cancer patient prognosis. However, current clinical probes are often single-modal with "always-on" signals, failing to provide complementary and precise guidance across all perioperative phases. To tackle this hurdle, we develop a biomarker-activatable, multimodal nanoprobe - - based on redox-mediated manganese valence switching for tumor-specific, perioperative image-guided surgery.

Introduction: Fluorescence-guided surgery employs a near-infrared emitting dye or light source to enhance intraoperative visualization. This study reports the first-in-human application of the Endolumik fluorescence-guided calibration tube (EGCT) during laparoscopic sleeve gastrectomy (SG) and gastric bypass (GB).
Methods: Under IRB approval (NCT05486325), two surgeons performed 21 laparoscopic SG and 10 GB procedures using EGCT.
