Cancer surgery demands the utmost precision, where accurate identification of tumor margins and understanding lymphatic pathways are paramount for successful treatment and patient recovery. In this critical domain, Indocyanine Green (ICG) dye has emerged as an indispensable tool, offering surgeons enhanced visualization capabilities that were previously unattainable. Its unique fluorescent properties, activated by near-infrared light, allow for real-time imaging of delicate structures, significantly improving the precision of oncological procedures.

One of the most impactful applications of ICG dye in cancer surgery is its ability to clearly delineate tumor margins. During operations for various cancers, including breast and colorectal cancers, ICG is administered to highlight the extent of cancerous tissue. This visualization helps surgeons to confidently resect the tumor while preserving as much healthy surrounding tissue as possible, thereby minimizing morbidity and improving aesthetic and functional outcomes. For instance, in breast cancer lumpectomies, the precise visualization afforded by ICG can lead to lower rates of re-excision.

Furthermore, ICG plays a pivotal role in sentinel lymph node (SLN) mapping, a crucial step in staging many types of cancer, such as breast cancer and melanoma. By injecting ICG near the tumor site, surgeons can visualize the lymphatic channels and identify the first lymph nodes to which cancer cells are likely to spread. This targeted approach allows for accurate staging and helps surgeons avoid unnecessary extensive lymph node dissections, which can lead to complications like lymphedema. The high sensitivity and safety profile of ICG make it a preferred agent for this procedure, offering a reliable alternative to radioactive tracers or blue dyes.

The integration of ICG with minimally invasive surgical techniques, including laparoscopy and robotic surgery, further amplifies its benefits. These advanced platforms, coupled with ICG fluorescence imaging, provide surgeons with magnified, three-dimensional views of the surgical field. This enhanced visual feedback is critical for navigating complex anatomical structures and executing delicate maneuvers with greater accuracy. For example, in robotic colorectal surgery, ICG aids in assessing bowel perfusion and identifying optimal transection lines, thereby reducing the risk of anastomotic leaks.

Beyond its direct role in visualization during surgery, ICG is also utilized for assessing organ perfusion, particularly in procedures involving the gastrointestinal tract and liver. Ensuring adequate blood supply to reconstructed tissues, such as gastric tubes during esophagectomy or bowel segments during colectomies, is vital for preventing complications. ICG fluorescence angiography provides real-time feedback on tissue vascularity, allowing surgeons to make informed decisions that promote successful healing and reduce the incidence of postoperative issues.

As the field of surgical oncology continues to evolve, the applications of ICG are expanding. Ongoing research into nanoparticle formulations and targeted delivery systems promises to further enhance its specificity and efficacy.
