Study Details

Study Description

Brief Summary

At present, there are relatively clear treatment guidelines for colorectal cancer with oligometastases, while the treatment mode for resectable esophageal cancer with oligometastases is not clear and there is a lack of research results in this field. The aim of this study is to provide evidence of the optimal therapy model for the local resectable esophageal cancer with oligometastases ESCC patients, by investigating whether 2-year OS of the patients could benefit from additional local consolidative esophagectomy.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Esophagectomy
N/A

Detailed Description

This study was designed as a multicenter, open-label, randomized controlled prospective clinical study. The experimental group (group A) received additional esophagectomy after 3-month systemic treatment, and the control group (group B) received only systemic treatment. 2-year OS, 3-year PFS and OS were observed in the two groups.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Additional Local Consolidative Esophagectomy Group

The patient in this arm will go on esophagectomy base on tracitional systemic therapy.

Procedure: Esophagectomy
Esophagectomy for esophageal cancer and regional lymph nodes dissection.

No Intervention: Traditional Systemic Therapy Group

The patients in this arm will receive traditional therapy, including chemotherapy, immunotherapy, radiotherapy, ect.
