Effect of Cervical Paraesophageal Lymph Node Metastasis Versus Supraclavicular Lymph Node Metastasis on the Overall Survival of Patients With Thoracic Esophageal Squamous Cell Carcinoma: An Observational Study

Effect of Cervical Paraesophageal Lymph Node Metastasis Versus Supraclavicular Lymph Node Metastasis on the Overall Survival of Patients With Thoracic Esophageal Squamous Cell Carcinoma: An Observational Study

The goal of this observational study is to learn about in health conditions of ESCC. The main question[s] it aims to answer are:

•Lymph node metastasis(LNM) in cervical paraesophageal or supraclavicular which influence OS more.

Participants will describe the main status quo after surgery

Researchers will compare Lymph node metastasis(LNM) in cervical paraesophageal and supraclavicular to see if dead.

Demographic and pathologic data, including gender, age, pathological T stage, pathological N stage, 8th tumor-node-metastasis (TNM) stage, tumor location, tumor grade, lymphovascular invasion, perineural invasion, LNM, cervical paraesophageal LNM, supraclavicular LNM, and radical resection, were collected from the Sichuan Cancer Hospital and Institute Esophageal Cancer Case Management (SCH-ECCM) database.

The inclusion criteria were as follows:

• patients who had undergone esophagectomy and
• patients who exhibited LNM in the supraclavicular region.

The exclusion criteria:

• tumor location outside the thoracic region,
• pathological examination results confirming the presence of non-squamous cell carcinoma, - patients with both cervical paraesophageal LNM and supraclavicular LNM, or
• those with missing required data
