Abstract
Background: To investigate the clinical efficacy,safety and prognostic factors of the therapy that apatinib is used for maintenance treatment in patients with advanced esophageal squamous cell carcinoma. Methods: We select 46 patients with advanced esophageal squamous cell carcinoma treated with radiotherapy and chemotherapy in our hospital from January 2017 to February 2019, all of them were treatment with apatinib. Analysis the clinical efficacy, adverse reactions and prognostic factors. Meanwhile, the expression of patients’VEGFR-2、NF-kB was detected by immunohistochemical SABC method,and the microvessel density and microlymphatic tube density were counted.Analysis of the relationship between indicators and MVD, MLVD counts and the efficacy of apatinib.Results: We found that oral treatment of apatinib in VEGFR-2、NF-kB positive group was better than that in negative group. The partial remission rate of patients was 26.09%; the disease control rate was 67.39%.The main adverse reactions were hypertension (60.87%); hand and foot syndrome (34.77%); proteinuria (36.96%). The degree of adverse reactions was mainly grade 1~2. The median progression-free survival was 3.7 months and the median overall survival was 7.2 months. Log-Rank univariate analysis showed that the degree of adverse reactions and ECOG score were related to OS in patients with advanced esophageal squamous cell carcinoma.Cox multivariate regression analysis showed that the degree of adverse reactions and ECOG score were independent factors affecting OS in patients with advanced esophageal squamous cell carcinoma.Conclusion: Positive expression of VEGFR-2 and NF-kB can be used as a biological reference target for targeted treatment of oral apatinib. Apatinib has a certain clinical effect in the maintenance treatment of advanced esophageal squamous cell carcinoma patients after treatment, with mild adverse reactions and high safety.
