Background:
The necessity of the standard D2 gastrectomy for elderly patients with advanced gastric cancer (GC) is controversial because only limited data are available to demonstrate its oncological benefit for them. Our aim was to compare the outcomes of D2 and Non-D2 and to evaluate the survival benefit of D2 laparoscopic gastrectomy (LG) in elderly patients.
Methods:
We retrospectively identified 865 patients with GC who underwent radical LG at our hospital between 2011 and 2017. Patients aged ≥75 years who were diagnosed with clinical T1N+ or clinical T2-4 were eligible. The primary outcome was the 3-year overall survival (OS) rate. The confounding factors were minimized using propensity score matching.
Results:
This study included 119 patients (63 D2 LG and 56 Non-D2 LG), and 52 patients (26 each for D2 LG and Non-D2 LG) were analyzed after matching. Although no significant difference was found in overall major complications (P=1.00), complications tended to occur in the D2 group (D2 vs. Non-D2 =3.9% vs. 0%). No differences in the 3-year OS were noted between the two groups (68.8% vs. 68.8%; HR 1.53, 95% CI: 0.56-3.19).
Conclusions:
This study demonstrated the possible association between D2 LG and increased complication rate and no survival benefit of D2 LG in elderly patients.
