Brief summary

The prognosis and safety of patients with locally advanced esophageal squamous cell carcinoma were compared with different neoadjuvant therapy modes in multi-cancer centers in China

Detailed description

Neoadjuvant chemoradiotherapy or neoadjuvant chemotherapy combined with surgery are the main treatment methods for patients with locally advanced esophageal squamous cell carcinoma, but some patients still have local recurrence or distant metastasis after surgery. In the era of immunotherapy, immune checkpoint inhibitor monotherapy or combined chemotherapy has become the first-line and second-line standard treatment for recurrent or metastatic esophageal cancer and has been recommended by NCCN guidelines. However, relevant studies on immunotherapy's participation in neoadjuvant therapy have shown good results, but it is still in its initial stage, and its efficacy needs further research and discussion.Thus, we compared the prognosis and safety of patients with locally advanced esophageal squamous cell carcinoma who received different neoadjuvant therapy before surgery, including neoadjuvant chemoradiotherapy, neoadjuvant chemotherapy, neoadjuvant chemotherapy combined with immunotherapy, and neoadjuvant chemoradiotherapy combined with immunotherapy in several cancer centers in China.

Design outcomes

Primary

MeasureTime frameDescription
Comparison of pathological complete response rate (pCR) after surgical resection in patients with locally advanced esophageal squamous cell carcinoma receiving different neoadjuvant therapy2015.1.1-2023.12.31Pathological complete response (pCR) is defined as the absence of residual tumor cells after evaluation of removed tumor tissue and regional lymph nodes.
Comparison of major pathological response (MPR) after surgical resection in patients with locally advanced esophageal squamous cell carcinoma receiving different neoadjuvant therapy2015.1.1-2023.12.31Major pathological response (MPR) is defined as a tumor that has significantly shrunk or decreased in the pathological evaluation, but still has a small number of residual tumor cells.

Secondary

MeasureTime frameDescription
Comparison of the overall survival (OS) after surgical resection in patients with locally advanced esophageal squamous cell carcinoma receiving different neoadjuvant therapy2015.1.1-2025.12.31OS is defined as the time from the start of enrollment to death from any cause
Comparison of the disease-free survival (DFS) after surgical resection in patients with locally advanced esophageal squamous cell carcinoma receiving different neoadjuvant therapy2015.1.1-2025.12.31DFS difined as the time between the start of the enrollment and the recurrence of disease, or death from any cause.

Other

MeasureTime frameDescription
Comparison of incidence of treatment-related adverse evants after surgical resection in patients with locally advanced esophageal squamous cell carcinoma receiving different neoadjuvant therapy2015.1.1-2025.12.31Adverse events are observed during the course of the study and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE V5.0).
