简要总结
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.
详细描述
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.
