Objective:. To establish the prognostic value of mean corpuscular volume (MCV) in patients with esophageal squamous cell carcinoma (ESCC) who have undergone esophagectomy. Background:. The MCV increases in patients with high alcohol and tobacco consumption. Such a lifestyle can be a risk factor for malnutrition, comorbidities related to those habits, and multiple primary malignancies, which may be associated with frequent postoperative morbidity and poor prognosis. Methods:. This study included 1673 patients with ESCC who underwent curative esophagectomy at eight institutes between April 2005 and November 2020. Patients were divided into normal and high MCV groups according to the standard value of their pretreatment MCV. Clinical background, short-term outcomes, and prognosis were retrospectively compared between the groups. Results:. Overall, 26.9% of patients had a high MCV, which was significantly associated with male sex, habitual smoking and drinking, multiple primary malignancies, and malnutrition, as estimated by the body mass index, hemoglobin and serum albumin values, and the Geriatric Nutritional Risk Index. Postoperative respiratory morbidity (P = 0.0075) frequently occurred in the high MCV group. A high MCV was an independent prognostic factor for worse overall survival (hazard ratio, 1.27; 95% confidence interval, 1.049–1.533; P = 0.014) and relapse-free survival (hazard ratio, 1.23; 95% confidence interval, 1.047–1.455; P = 0.012). Conclusions:. A high MCV correlates with habitual drinking and smoking, malnutrition, and multiple primary malignancies and could be a surrogate marker of worse short-term and long-term outcomes in patients with ESCC who undergo esophagectomy.
