In this monocentric retrospective analysis of prospectively collected follow-up data, 157 patients were included after applying the exclusion criteria: Age below 18, primary bone marrow disease, hereditary forms of anemia, postoperative tumor recurrence and R1/R2 situation. 103 patients (=66%) belonged to the esophagectomy group and 54 patients (=34%) to the (sub)total gastrectomy group. Preoperatively and three, six, twelve, 18, and 24 months postoperatively the following laboratory parameters were collected and descriptively analyzed: Hemoglobin, MCV, MCH, serum iron, ferritin, transferrin, and vitamin B12.\u0000 Two years after the oncological resection 28% of patients with esophagectomy, EE, and 48% of patients with (sub)total gastric resection, (S)GE, show anemia. Normocytic anemia was the dominant type. The MCV distribution of anemic patients in the EE group was as follows: 3% microcytic, 77% normocytic, and 20% macrocytic. The anemic patients in the (S)GE group show the following MCV distribution: 16% microcytic, 81% normocytic, and 3% macrocytic.
