surgery based on PET-CT/MRI staging
Eligibility Criteria
You may qualify if:
- Histologically confirmed adenocarcinoma or squamous cell carcinoma of the esophagus, including AEG I and AEG II tumors in the primary situation
- Planned surgical treatment of esophageal carcinoma
- Possible staging advantage through FAPI PET/CT diagnostics
- Patient information and written consent
- \> KI 60% or ECOG 0/1 (at least: self-sufficiency)
- Age ≥ 18 years
You may not qualify if:
- Previous radiation therapy in the tumor region
- Previous tumor disease with \< 5 years of remission
- Surgical therapy is not functionally or technically possible
- Distant metastasis
- Patient is not capable of giving consent
- Concurrent participation in another clinical trial that could affect the results of this trial or the other trial
- Illnesses that do not allow the person concerned to assess the nature and scope as well as possible consequences of the clinical study
- pregnant or breastfeeding women
- Signs that the person taking part is unlikely to comply with the therapy (e.g. unwillingness to cooperate)
