Study Details

Study Description

Brief Summary

Neoadjuvant chemoradiotherapy treatment represents the standard approach for resectable locally advanced esophageal squamous cell carcinoma. The incidence of pulmonary infection and other perioperative complications were higher in patients who received esophagectomy and neoadjuvant chemoradiotherapy than those without neoadjuvant treatment and surgery patients. However, reliable clinical data can quantify the damage degree of immunologic function caused by chemotherapy and radiotherapy is still unknown. This project regards the level of lymphocyte and immunocyte in peripheral blood as a quantitative index to reflect the dynamic change of the immunologic function of patients with locally advanced esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy treatment. Meanwhile, the investigators will also investigate the relationship between the level of lymphocyte and immunocyte in peripheral blood and the response rate of neoadjuvant therapy.

Condition or Disease	Intervention/Treatment	Phase
Esophageal Squamous Cell Carcinoma Neoadjuvant Therapy Surgery

Detailed Description

Peripheral blood will be collected from patients who will undergo esophagectomy and/or neoadjuvant therapy. The setting time is before chemoradiotherapy, finishing chemoradiotherapy, pre-operation, postoperative day 1, day 3, day 5, and day 7. These blood samples will be used for detection and analysis in lymphocyte and immunocyte by flow cytometry.
