Abstract
Objectives
Some previous studies reported that the levels of a low-density lipoprotein receptor relative with 11 ligand-binding repeats (LR11) was a prognostic marker in some malignant tumors; however, whether LR11 is related to survival in patients with esophageal cancer remains unclear.
Methods
In this study, we measured LR11 in the preoperative serum of 46 patients of esophageal cancer who undergoing surgery using a sandwich enzyme-linked immunosorbent assay (ELISA) method with anti-LR11 monoclonal antibodies. We investigated the correlation between the level of LR11 and survival of patients with esophageal cancer. Clinicopathological data were retrospectively retrieved from our institution's database.
Results
The patients were divided into two groups (low LR11 and high LR11) based on the level of LR11. There was no statistical difference in clinicopathological factors between these two groups. The low LR11 group had a significantly longer overall survival than the high LR11 group.
Conclusions
LR11 can be measured with a relatively simple ELISA and is potentially a new prognostic marker for esophageal cancer.
