NCT06945718

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 3-year disease free survival rate

    Disease-free survival is calculated from the day of surgery to the day of recurrence or death

    3 years

Secondary Outcomes (21)

  • Total number of retrieved lymph nodes

    30 days

  • Noncompliance rate of lymph node dissection

    30 days

  • Relationship between fluorescent lymph nodes in group A and total number of lymph nodes in group A

    30 days

  • Relationship between fluorescent lymph nodes in Group A and positive lymph nodes in Group A (positive rate)

    30 days

  • Relationship between fluorescent lymph nodes in Group A and negative lymph nodes in Group A (false positive rate)

    30 days

  • +16 more secondary outcomes
