Background:
Because the incidence of early gastric cancers has been increasing in Asian countries, postoperative quality of life has received considerable attention in addition to oncological outcomes.
Methods:
Eighty-four patients with clinically early gastric cancers were enrolled in this retrospective study. Among them, 35 patients underwent total gastrectomy (TG) and 49 patients underwent limited proximal gastrectomy (PG). Blood chemistry, changes in body weight, and oncological outcomes were compared between the two groups.
Results:
Postoperative hemoglobin levels and body weights were significantly lower in the TG group than in the PG group, and there were no significant differences in the levels of other nutritional indicators such as serum total protein and total cholesterol. However, the overall survival rates of patients in the PG group were similar to those of patients in the TG group (5-year survival rates, 95 versus 97 %, respectively; p = 0.86).
Conclusions:
Limited proximal gastrectomy with regional lymph node dissection has possible positive effects on maintaining body weight and preventing postgastrectomy anemia with similar oncological outcomes to total gastrectomy in patients with early gastric cancers.
