Nonmetastatic esophageal cancer can demonstrate a high local recurrence rate even under the standard treatment. We evaluated platelet counts before and after concurrent chemoradiotherapy (CCRT), neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio for predicting esophageal cancer prognosis under CCRT. Newly diagnosed patients with esophageal cancer (stages IA–IIIC) who underwent CCRT during January 2013–December 2017 were enrolled. The data were collected retrospectively. Overall survival (OS), time to progressive disease (TPD), and time to metastasis (TM) were recorded for indicating prognosis. Kaplan–Meier curves were plotted and univariate and multivariate analyses were performed. In total, 105 patients were enrolled. The stages of esophageal cancer and surgery were associated with prognosis (i.e., OS, TPD, and TM). Based on TPD and TM, women had better prognosis than men. In the univariate analysis, high pre- and post-CCRT platelet counts (>300,000/μL), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) as well as low lymphocyte percentage were significantly associated with poor prognosis. However, in the multivariate analysis, only post-CCRT high platelet count (>300,000/μL) remained significantly associated with poor prognosis (P = .041, .045, and .023 for OS, TPD, and TM, respectively). Poor prognosis was observed in patients with high platelet counts, PLR, NLR, and low lymphocyte percentage. Surgery was an independent factor predicting better prognosis. Our findings may have clinical significance with regard to therapeutic decision-making.

Background: Enteral feeding tubes used to manage the nutritional status of esophageal cancer were evaluated regarding their effectiveness in patients receiving neoadjuvant therapy. Patients and Methods: A retrospective study evaluating patients with esophageal squamous cell carcinoma undergoing neoadjuvant therapy between 2001 and 2014 was conducted at a medical center. Hospital patients' records for enteral access (EA) insertion and treatment outcomes were statistically analyzed. Results: Patients with EA at initial diagnosis had lower body mass index than the group without EA (p=0.012). Chemotherapy-related adverse events with grade 3-4 mucositis were significantly less frequent in the EA group (p=0.008), and grade 3-4 anemia was significantly more frequent (p=0.012). The 4-year mortality rate was 63.0% in the EA group and 67.7% in the group without EA (p noninferiority =0.035), which met the non-inferiority criterion with a non-inferiority margin of 10%. Conclusion: Patients with esophageal squamous cell carcinoma with malnutrition status undergoing neoadjuvant therapy with EA showed an improved outcome at maintaining nutritional status, reduced severity of mucositis and improved survival rate.
