Surgical excision is still the most used treatment in the treatment of malignant tumors. Yet, the level of success of the treatment depends on extension of the excision beyond the margins of the tumor or establishing clear margins.
Decision on the clearance achieved can be made by intraoperative examination of the margin by the use of methods such as frozen sections and more recently imprint cytology.
The process however requires time that can extend up to an hour for the pathological evaluation of sections. During this time the surgical team has to stand by and the patient maintained under anesthesia. This delay further lengthens an often long surgical procedure and adds to the surgical risk. Additionally the finding of actual clearance is limited to the sites and number of sections taken.
A technique that can color code the tumor affected tissue and nerves healthy or otherwise has been developed and is under trial.
Watch the video to find out more about the same by the surgeon Queyn Nguyeninvolved in the development of the technique..
