Gastric Cancer, Lymph Node Metastases
Conditions
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

Intervention model description
Group A (Study Group): Laparoscopic gastrectomy group with the use of near-infrared imaging (ICG group) Group B (Control Group): Laparoscopic gastrectomy group without the use of near-infrared imaging (Non-ICG group)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| Total number of retrieved lymph nodes | 30 days | Total number of retrieved lymph nodes |
