Taking patients with locally advanced gastric adenocarcinoma (cT2-4a, N-/+, M0) as the research subjects, to evaluate whether the clinical efficacy of laparoscopic beyond D2 regional lymph node dissection for gastric cancer with indocyanine green tracer is better or not.
None
None
Age from 18 to 75 years Primary gastric adenocarcinoma (papillary, tubular, mucinous, signet ring cell, or poorly differentiated) confirmed pathologically by endoscopic biopsy cT2-4a, N-/+, M0 at preoperative evaluation according to the AJCC Cancer Staging Manual, 8th Edition
Cohort
Prospective
beyond D2 regional lymph node dissection
Procedure/Surgerydissect the lymph nodes outside the extent of D2 LN region.
3-year disease free survival rate
Disease-free survival is calculated from the day of surgery to the day of recurrence or death
Total number of retrieved lymph nodes
Total number of retrieved lymph nodes
Noncompliance rate of lymph node dissection
The LN dissection rate was determined by the number of patients in whom a LN station was harvested divided by the total number of patients who required retrieval at the corresponding LN station. Within the scope of D2 dissection, LN noncompliance was defined as the absence of LNs that should have been resected from \> 1 LN station.
Relationship between fluorescent lymph nodes in group A and total number of lymph nodes in group A
Relationship between the number of fluorescent lymph nodes in group A and total number of lymph nodes in group A
Relationship between fluorescent lymph nodes in Group A and positive lymph nodes in Group A (positive rate)
The number of positive lymph nodes in fluorescent lymph nodes is divided by the number of total fluorescent lymph nodes in Group A (True positive rate).
