Plain English Summary
Background and study aims
Cancer in the esophagus (gullet) and the gastroesophageal junction (gullet-stomach junction) are serious diseases. Despite diagnostic and treatment progress in recent years, only around 1 in 5 (20%) of the patients who gets these diseases can be cured. The best treatment results are achieved with a combination of anticancer treatments (radiation and drug treatment) followed by surgery. This combination therapy is effective on a group level, but for the individual patient it is very hard to know if the radiation therapy and chemotherapy (medicines) will be effective. If this could be known for each patient, a better tailor-made treatment plan could achieved. We want to improve the ability to see who responds well to this treatment before surgery and promising results from MRI in other types of tumors gives us hope that we can do this for esophageal and gastroesophageal junctional cancer as well.
Who can participate?
Adults over the age of 17.
What does the study involve?
Participants are asked to join this study at the time of their diagnosis. The study involves one MRI scan before and one after the anticancer treatment that is given before surgery. The first scan is used instead of the routine method used today (PET-CT) and the second scan is added for the purpose of this study. The scan takes around 60-90 minutes and involves lying on your back in a small space.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part. In the future, we hope to be able to use the knowledge gained from this study to formulate new strategies to improve patient survival and quality of life.
Where is the study run from?
This study is run from the Department of Surgical Sciences at Uppsala University Hospital, Uppsala, Sweden.
When is the study starting and how long is it expected to run for?
September 2018 to 2025.
Who is funding the study?
The Swedish Cancer Society (Cancerfonden)

Study information
Scientific title
PET-MRI for prediction of treatment response to neoadjuvant treatment of cancer in the esophagus and the gastroesophageal junction
Acronym
PREciSE II (Pet magnetic RESonance of Esophagus II)
Study hypothesis
PET-MRI can combine data from PET with radiomic characteristics of the tumor in order to improve the prediction of complete pathological response to neoadjuvant treatment in esophageal cancer and cancer in the gastroesophageal junction.
Ethics approval
Regional ethics review board Uppsala, 10/07/2018, ref: 2018/226
Study design
We aim to evaluate PET-MRI in a cross-sectional cohort of patients planned for neaodjuvant treatment followed by resectional surgery for esophageal cancer and cancer of the gastroesophageal junction.

Condition
Esophageal cancer and cancer in the gastroesophageal junction.
Intervention
The recruited patient undergoes a PET-MRI at diagnosis and one before surgery. This is a 60- to 90-minute investigation. The surgical specimen is investigated according to clinical routine for TNM (tumour, node metastasis) staging and tumor regression grade according to Becker. The follow up is performed in accordance with clinical routine. After that the patient is followed in our national registries for registration of death and up to 5-year survival rates can be included in future analyses.

Primary outcome measure
The main outcome measure is specificity and sensitivity for prediction of complete pathological response to neoadjuvant treatment. The radiomic results will be calculated by an operated blinded for other clinical data and the score will be entered into a dataset. Other radiologic markers (SUV-max etc) will be entered as well. The pathological examination will also be entered into a blinded dataset and correlation analyses will be performed.
Secondary outcome measures
Tumor immune cell population composition in relation to pathological clinical response. Plasma and tumor samples before and after neoadjuvant therapy are frozen and saved for future analysis. In circulating plasma, biomarker assays will be preformed before, during and after neoadjuvant treatment along with appropriate bioinformatic statistical interpretation (Oling, Immunooncology panel). In addition to this, immunohistochemical analyses of tumour material (CD4, FoxP3, CD8/CD45RO andEn CD20), analyses for immunology gene-expression before and after neoadjuvant treatment (Nanostring, nCounter Immunology ans Inflammation panels) will be performed.
