About this study

Official title: CT Scan-Based Radiomics and Molecular Expression Predictive Model to Assess Tumor Regression Grade Following Perioperative Chemotherapy in Esophago-Gastric Junction and Gastric Cancer

The aim of this study is to develop a CT scan-based radiomics predictive model about tumor regression grade (TRG) in patients with esophago-gastric junction (EGJ) ang gastric cancer undergoing perioperative chemotherapy. The molecular expression of the neoplasms will be evaluated to assess its association with the TRG and the radiomic features.

Read the detailed description
  • To compare the radiomic features of the CT scans at the time of diagnosis (T0) and at the end of the preoperative chemotherapy (T1) in order to predict the TRG with the texture analysis on the first CT scan.

A non-good response (non-GR) has shown to be predictable with texture analysis on the pre-treatment CT scan.

Therefore, we hypothesize that texture analysis could let to identify the good response patients.

  • To find correlation between the molecular expression of the tumor and the radiomics features.

Texture analysis on the pre-chemotherapy CT scan founded that entropy and compactness were higher and uniformity lower in responders. Nonetheless the association between radiomics features and molecular expression has not been investigated yet.

Therefore, we hypothesize to add some others radiomics signatures to the analysis and to find an association with the molecular expression.

  • To find correlation between the molecular expression of the tumor and the TRG.

MSI gastric cancer has been shown to be less responsive to preoperative chemotherapy.

Therefore, we hypothesize to confirm this result.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CT scanDiagnostic test

    Also called FLOT chemotherapy, Radical Gastrectomy with D2 Lymphadenectomy, Radical Esophagogastrectomy with D2 Lymphadenectomy

    Patients undergoing CT scan staging for gastric and EJ junction cancer + perioperative chemotherapy (FLOT regimen) , CT scan re-staging and radical gastrectomy or esophagogastrectomy will be enrolled in the study

What is being measured

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

  1. Predictive performance of radiomics analysis on the pre-treatment CT scan.

    Comparing the radiomic features of the CT scans at the time of diagnosis (T0) and at the end of the preoperative chemotherapy (T1) in order to predict the TRG with the texture analysis on the first CT scan.

    Measured: 2 months

Secondary outcomes (3)
  1. Association of the radiomics features with the molecular expression of the tumor.

    Texture analysis on the pre-chemotherapy CT scan founded that entropy and compactness were higher and uniformity lower in responders. Nonetheless the association between radiomics features and molecular expression has not been investigated yet.

    Therefore, we hypothesize to add some others radiomics signatures to the analysis and to find an association with the molecular expression.

    Measured: 2 months

  2. Evaluation of the association between TRG and the molecular expression of the tumor.

    Investigate if the molecular expression of the tumor can influence the TRG

    Measured: 2 months

  3. Association between radiomics and molecular expression in regards to long-term outcomes

    Analysis of the 3 and 5y DFS and OS of patients with the radiomics and molecular expression profile

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Gastric Cancer and Adenocarcinoma of the Stomach, run by University of Roma La Sapienza at 5 sites in 2 countries.

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 6 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: under way, not looking for participants, as of the sponsor's last update on 9 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Italy, Netherlands. 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?

This study is still under way. Results are not available in the source record yet.

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?

Predictive performance of radiomics analysis on the pre-treatment CT scan. (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 May 2024.
