Preoperative restrictive pulmonary dysfunction influences the survival after gastrectomy for elderly patients with gastric carcinoma

We aimed to evaluate the prognostic impact of pulmonary dysfunctions and their relationships with other possible prognostic factors, especially sarcopenia, in elderly patients with gastric carcinoma (GC). In total, 402 elderly GC patients (≥ 75 years) who underwent radical gastrectomy were retrospectively reviewed. Restrictive and obstructive pulmonary dysfunction were defined as %VC
