Purpose
Several studies have evaluated the association between ABO blood group and the prognosis of various types of cancer; however, little is known about the relationship between ABO blood group and esophageal squamous cell carcinoma (SCC). We investigated how ABO blood group and clinicopathological characteristics are related to the survival of Japanese patients with esophageal SCC.
Methods
We reviewed the medical records of 181 patients who underwent surgery for esophageal SCC between June, 2004 and December, 2015 and analyzed the association between ABO blood group and clinicopathological factors. Clinicopathological factors were also evaluated by univariate and multivariate analyses for possible association with survival.
Results
The prevalence of each blood group was as follows: A, 35.5%; B, 22.4%; O, 32.8%; and AB, 8.2%. The 5-year overall survival of all patients was 37.1%. Patients with non-type B blood had significantly worse 5-year overall survival than those with type B blood (30.2 vs. 58.8%, P < 0.05).
Conclusions
ABO blood groups were associated with the survival of Japanese patients with esophageal SCC. Patients with non-B blood groups had significantly worse overall survival than those with the B blood group.
