Increasing number of clinical studies have shown that laparoscopic distal gastrectomy (LDG) with D2 lymph node (LN) dissection is an effective method for the treatment of advanced gastric cancer (AGC). However, reports on the technical feasibility and oncology efficacy of laparoscopic total gastrectomy (LTG) in the treatment of AGC are rare.


A retrospective analysis of the clinicopathologic data of 1313 patients with clinical stage of cT2-4aN0-3M0 undergoing laparoscopic radical gastrectomy with D2 LN dissection from June 2007 to December 2013 was performed. Noncompliance was defined as patients with more than one LN station absence as described in the protocol for D2 lymphadenectomy in the Japanese Gastric Cancer Association (JGCA). According to the literature, it was subdivided into LN compliance group (all LN stations were detected), minor LN noncompliance group (1–2 LN stations were not detected), major LN noncompliance group (more than 2 LN stations were not detected). Based on the LN noncompliance, the surgical indications of LTG were analyzed with LDG as control.


Among the 1313 patients, 197 (39.20%) patients and 321(39.71%) patients in the LDG group and the LTG group had minor LN noncompliance, 59(11.70%) patients and 163(20.10%) patients had major LN noncompliance. The difference in the extent of LN noncompliance between the two groups was statistically significant (p < 0.001). COX proportional hazards regression analysis elucidated that the LN noncompliance was an independent prognostic factor for overall survival (OS). BMI ≥ 25 kg/m2 and the history of previous abdominal surgery (PAS) were independent risk factors for major LN noncompliance in LTG group (p < 0.05), with which patients were defined as a LN noncompliance high-risk group. With the exception of LN noncompliance high-risk group, the difference in the extent of LN noncompliance between LTG group and LDG group was still statistically significant (p = 0.008). Tumor diameter > 60 mm is a preoperative risk factor for station #5 LN noncompliance, and no preoperative risk factors for station #6 LN noncompliance were found, with which patients were defined as LN noncompliance middle-risk group.


LN noncompliance is an independent prognostic factor for poor prognosis in patients after LTG. Based on this finding, patients with BMI ≥ 25 kg/m2, history of PAS and tumor diameter > 60 mm in the advanced stage of upper-middle gastric cancer represent high/middle-risk groups with LN noncompliance in LTG surgery, which should be carefully selected.
