BACKGROUND: Pulmonary segmentectomy with radical lymphadenopathy has been considered effective to manage small primary lung cancers [1, 2]. This procedure provides the advantages of minimal invasive surgery and is reported sufficient for safe margin. However, segmentectomy is more difficult to be performed than lobectomy because intersegmental plane cannot be detected easily. Several methods have been reported for identifying the actual intersegmental plane [3-7], but the sensitivity of these methods is limited to the lung conditions like patients with emphysematous lung and needed skilled surgeon to perform...

PURPOSES: Sentinel node identification using indocyanine green (ICG) is not only simpler, but also more cost-effective, than using radioisotope tracers. We herein examined the utility and pitfalls of sentinel node (SN) identification using ICG during segmentectomy in patients with cT1N0M0 non-small cell lung cancer (NSCLC). METHODS: ICG was injected around the tumor after thoracotomy, followed by segmentectomy and lymph node dissection, in 135 patients with cT1N0M0 NSCLC...

Surgery is the most effective method to cure patients with solid tumors. New techniques in near-infrared (NIR) cancer imaging are being used to identify surgical margins and residual tumor cells in the wound. Our goal was to determine the optimal time and dose for imaging solid tumors using Indocyanine Green. Syngeneic murine flank tumor models were used to test NIR imaging of ICG at various doses ranging from 0 to 10 mg/kg. Imaging was performed immediately after injection and up to 72 hours later. Biodistribution in the blood and murine organs were quantified by spectroscopy and fluorescence microscopy...

PURPOSE: In most general thoracic operations performed via standard posterolateral thoracotomy, such as for descending aortic aneurysms and lung cancer, the latissimus dorsi (LD) muscle is divided. However, division of the LD can hamper reconstructive surgery because the initial operation creates unstable blood flow to the divided LD. We conducted this study to assess blood flow in a divided distal LD muscle flap using intraoperative indocyanine green-fluorescence angiography (ICG-FA) with the Hyper Eye Medical System(®) (Mizuho Medical Co...

Nasopharyngeal carcinoma (NPC) is an EBV-associated epithelial malignancy prevalent in southern China. Presence of treatment-resistant cancer stem cells (CSC) may associate with tumor relapse and metastasis in NPC. ICG-001 is a specific CBP/β-catenin antagonist that can block CBP/β-catenin-mediated transcription of stem cell associated genes and enhance p300/β-catenin-mediated transcription, thereby reducing the CSC-like population via forced differentiation. In this study, we aimed to evaluate the effect of ICG-001 on the CSC-like population, and the combination effect of ICG-001 with cisplatin in the C666-1 EBV-positive NPC cells...

A hydrophobic gadolinium bis(naphthalocyanine) sandwich complex (GdSand) possessing several absorbances across visible and infrared wavelengths (up to 2500 nm) was solubilized in aqueous solution by uptake into a nascent mutant high-density lipoprotein (HDL) nanocarrier. The HDL nanocarrier was additionally functionalized with a trans-activator of transcription peptide sequence to promote efficient cell penetration of the drug delivery system (cpHDL). The dye-loaded nanocarrier (GdSand@cpHDL) exhibited photothermal heat generation properties upon irradiation with near-infrared (NIR) laser light, with controllable heat generation abilities as a function of the incident laser light power...

PURPOSE: Lymphatic spread of lung carcinoma to the mediastinum is a key determinant of prognosis. The lymph flow often carries metastases from the pulmonary segment directly into the mediastinal lymph nodes, without passing through the hilar nodes. This phenomenon is termed as "skip metastasis." This study investigated the subpleural lymphatic flow to the mediastinum using indocyanine green (ICG) with a near-infrared fluorescence imaging system. METHODS: Seventeen patients with lung cancer were enrolled in this study...
