The prevalence and clinical significance of postgastrectomy anemia in patients with early-stage gastric cancer: A retrospective cohort study

Anemia was common among gastric cancer patients after gastrectomy. Total gastrectomy and advanced T stage were identified as independent risk factors for postgastrectomy anemia. In addition, anemia might be associated with nutritional problems and a poor prognosis. Thus, regular monitoring and appropriate management of postgastrectomy anemia are important for early-stage gastric cancer patients with a long life expectancy.
