- Registration Number
- NCT04611997
- Lead Sponsor
- Fujian Medical University
- Brief Summary
Patients with locally advanced gastric adenocarcinoma (cT2-4a N-/+ M0) were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in guiding laparoscopic D2 lymph node dissection for gastric cancer after neoadjuvant chemotherapy by comparing injection ICG group and non-injection ICG group

- Primary Outcome Measures
Name Time Method 3-year disease free survival rate 3 years Disease-free survival is calculated from the day of surgery to the day of recurrence (When the specific date of recurrence of the tumor is unknown, the ending point is the date of death due to tumor causes). In the event that neither death nor recurrence of the tumor are observed, the end point is the final date that a patient is confirmed as relapse-free.
- Secondary Outcome Measures
Name Time Method Total number of retrieved lymph nodes 30 days Total number of retrieved lymph nodes
