Fluorescent Navigation Technology in Radical Resection of Pancreatic Cancer

This study intends to design the prospective, exploratory, single center clinical study, using targeted EGFR fluorescence imaging agent (anti-EGFR-IR800CW) and fluorescent navigation technology, in its lymph node tracing, intraoperative tumor localization, accurate determination of resection margin, and explore its clinical significance in radical surgical resection of pancreatic cancer.

The overall prognosis of pancreatic cancer is poor. For resectable patients, adjuvant chemotherapy is performed after surgery, which has become the standard and standard treatment recommended by various guidelines. Preoperative neoadjuvant therapy is proved to improve the R0 resection rate and reduce the lymph node metastasis rate, thus prolonging the postoperative recurrence-free survival time and increasing the survival benefit of patients. But despite adequate preoperative and postoperative treatment, the patient benefit remains limited. In pancreatic cancer surgery, improving the R0 resection rate, increasing the positive lymph node resection rate, and accurately identifying small metastases to accurately stage, can improve the prognosis of patients to a certain extent. Therefore, this study intends to design the prospective, exploratory, single center clinical study, using targeted EGFR fluorescence imaging agent (anti-EGFR-IR800CW) and fluorescent navigation technology, in its lymph node tracing, intraoperative tumor localization, accurate determination of resection margin, and explore its clinical significance in radical surgical resection of pancreatic cancer.
