  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with ESCC undergoing nCRT at the Department of Thoracic Surgery, Zhongshan Hospital of Fudan University (training cohort), and the Department of Thoracic Surgery, Zhongshan Hospital Xiamen Branch (validation cohort), between January 2010 and February 2019 were reviewed. The inclusion criteria were (I) thoracic ESCC; (II) McKeown or Ivor-Lewis transthoracic approach; (III) locally advanced resectable tumor with cT3-4aNany staging treated with nCRT; (IV) no history of concomitant or prior malignancy.

Who may be able to join

Who cannot join

  • Patients receiving neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma without surgical resection

About this study

Official title: Primary Tumor Burden Score: A Novel Staging Parameter Superior to ypT-category for Esophageal Squamous Cell Carcinoma After Neoadjuvant Chemoradiotherapy

In this case-only study, the investigators try to define a novel staging parameter, the Primary Tumor Burden Score (PTBS).

Read the detailed description

In this case-only study, the investigators try to define a novel staging parameter, the Primary Tumor Burden Score (PTBS), which will combine the proportion of residual primary tumor cells and pre-treatment pathological T stage (prepT stage). The investigators will also try to improve ypTNM stage by results of PTBS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Five-year survival of patients

    The survival of the patients was recorded by follow-up for five years after surgery.

    Measured: From surgery to the end of follow-up(at least 5 years later)

Questions about this trial

What is this clinical trial studying?

An observational study of Neoplasm, Esophagus and Neoplasm, Squamous Cell, run by Fudan University.

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 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 3 May 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Five-year survival of patients (time frame: From surgery to the end of follow-up(at least 5 years later)). 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 NCT05839002, which also lists 1 linked publication.

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 3 May 2023.
