Trial summary
The optimal interval between neoadjuvant chemradiotherapy and esophagectomy is still a question that needs to be explored for patients with esophageal squamous cell carcinoma.

About this study
Official title: Exploring the Optimal Timing of Minimally Invasive Surgery for Esophageal Squamous Cell Carcinoma After Neoadjuvant Chemoradiotherapy
The optimal interval between neoadjuvant chemradiotherapy and esophagectomy is still a question that needs to be explored for patients with esophageal squamous cell carcinoma. In this study, based on previous studies, the investigators divided patients into two groups with a cutoff value of 50 days. By comparing the overall survival and disease-free survival of the entire population and non PCR population, the investigators ultimately obtained the optimal surgical timing suitable for clinical use
Read the detailed description
background：Neoadjuvant chemoradiotherapy has gradually become a first-line treatment for esophageal squamous cell carcinoma patients. After the completion of neoadjuvant chemoradiotherapy, patients usually undergo minimally invasive surgery to ensure complete removal of the tumor and lymphatic tissue. However, the optimal interval between neoadjuvant chemoradiotherapy and minimally invasive surgery is still an unknown factor, and whether it affects postoperative disease-free survival (DFS) and overall survival (OS) of patients remains unknown. Therefore, the main purpose of this study is to explore the specific impact of the interval between neoadjuvant chemoradiotherapy and minimally invasive surgery on patients, and to find the optimal interval time.
methods：Patients who underwent neoadjuvant chemoradiotherapy and minimally invasive surgery from two institutions between October 2010 and September 2019 were included in this study. The time interval is defined as the days between the last time a patient receives neoadjuvant chemoradiotherapy and the execution of surgery. Based on past research, the interval between the two groups was determined to be 50 days. The main research result is the OS and DFS of different interval groups in the overall population and non-PCR population. A multivariate Cox regression model was established to determine the main factors affecting Patient's OS and DFS.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The optimal interval between neoadjuvant chemradiotherapy and esophagectomy is still a question that needs to be explored for patients with esophageal squamous cell carcinoma. In this study, based on previous studies, the investigators divided patients into two groups with a cutoff value of 50 days. By comparing the overall survival and disease-free survival of the entire population and non PCR population, the investigators ultimately obtained the optimal surgical timing suitable for clinical use

Questions about this trial
What is this clinical trial studying?
A study testing Neoadjuvant chemradiotherapy and Minimally invasive esophagectomy in people with Time, run by Shanghai Zhongshan Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The overall survival of the overall population (time frame: 5 years). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06364566, which also lists 24 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2024.
