The clinical impacts of lymphocyte-to-C-reactive protein ratio for esophageal cancer patients who receive curative treatment.

Abstract

We investigated the impact of the lymphocyte-to-C-reactive protein ratio (LCR) on esophageal cancer survival and recurrence after curative treatment. This study included 89 patients who underwent curative surgery followed by adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. LCR of 12,177 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rates. The OS rates at 3 and 5 years after surgery were 33.2% and 29.9% in the LCR low group, respectively, and 74.0% and 60.9% in the LCR high group, which amounted to a statistically significant difference (P = 0.001). The RFS rates at 3 and 5 years after surgery were 25.3% and 21.7% in the LCR low group, respectively, and 52.1% and 47.4% in the LCR high group, which amounted to a statistically significant difference (P = 0.001). A multivariate analysis demonstrated that the LCR was a significant independent risk factor for both the OS and RFS. LCR was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the LCR.
