Official title
Localization of Preoperative Endoscopic Tattooing Using Indocyanine Green(ICG)-Hyaluronic Acid Mixture (Luminomark) for Colorectal Cancer Surgery
Overview
Early-stage lesions are difficult to identify intraoperatively during colorectal cancer surgery. Therefore, preoperative lesion marking using a colonoscopic approach is crucial to confirm the location and extent of resection during surgery. Preoperative lesion location can help determine the optimal extent of resection, thereby increasing the accuracy of colorectal surgery. This is particularly true for cases requiring surgery after early-stage colorectal cancer or endoscopic tumor resection. Therefore, preoperative marking with indocyanine green (IDG) allows for laparoscopic identification of the lesion. This is crucial because it allows for precise lesion location, thereby enhancing surgical accuracy and preventing the need for unnecessary additional resections.
Detailed description
The recently developed indocyanine green (ICG)-hyaluronic acid mixture (LuminoMark™, Hanlim Pharm Co., Seoul, Republic of Korea) is a surgical marker combining indocyanine green with macroaggregated albumin (MAA). Its non-diffusing properties allow for precise lesion targeting. It addresses unmet needs of existing surgical markers, such as skin pigmentation and surgical site contamination. It effectively adsorbs onto cancerous lesions, enabling precise lesion location. Real-time tracking of the pigment allows for clear identification of the lesion's extent of removal, enhancing convenience and usability during surgery. It has already demonstrated superiority over existing labeling methods in a phase 3 clinical trial for breast lesions, receiving approval from the Ministry of Food and Drug Safety. Clinical trials are underway for various cancer types, including gastric and colon cancer, but it remains an over-approved drug.
Therefore, this study aimed to determine the accuracy of endoscopic labeling using a novel luminomarker for preoperative colon cancer lesion marking.
Interventions
- Drug LuminoMark inj. 0.2mL
* Endoscopic tattooing with Luminomark on submucosal layer of bowel * Location of injection : total 4 sites 1. Left lateral side of the tumor 2. Right lateral side of the tumor 3. opposite side of the tumor 4. distal side of the tumor * Dosage of injection: -at least 0.5cc per a site, total 2ml
Primary outcome measures
- Distance between endoscopic lesion markings and lesion location markings using luminomarkers for accuracy of tattooing [Time frame: Perioperative/Periprocedural]
Secondary outcome measures (1)
- post-procedure related complication [Time frame: through postoperative 4 days]
