Clinical Trial Summary

This trial on biomarker validation investigates the use of innovative re-staging FDG-PET parameters to detect highly chemoradiation (CRT) sensitive squamous cell carcinomas of the esophagus (SCEC) at the end of preoperative or definitive CRT.

Description:

This trial on biomarker validation investigates the use of innovative re-staging FDG-PET parameters to detect highly chemoradiation (CRT) sensitive squamous cell carcinomas of the esophagus (SCEC) at the end of preoperative or definitive CRT. Successful validation of this biomarker could lead to a more individualized approach for patients, i.e. organ preservation in highly chemoradiosensitive patients. Since favorable response to CRT is associated with better outcome of patients, the primary endpoint of the study is an improved event-free-survival (EFS) in responders receiving definitive CRT compared to non-responders. Additional quality of life and other important endpoints (side effects, overall survival, local control, occurrence of distant metastases) will be assessed in both treatment groups.

The investigated PET parameters are Maximum standardized uptake ratio (SURmax) of the primary tumor at week four of chemoradiation and change of maximum standardized uptake value of the non tumor affected esophagus (DeltaNTO).

To improve the treatment in non-responders in future trials, the study has two additional scientific support programmes included: Genetic sequencing of tumor tissue to identify targetable mutations and correlate these with novel imaging biomarkers of none-response on the one hand (biology based treatment optimization). On the other hand the study will include an additional observational study arm. In this arm patients with adenocarcinoma of the esophagus can be included. Our biomarker has only been established in squamous cell carcinomas, therefore it is an interesting exploratory question, if the parameter can also be applied to patients with adenocarcinomas of the esophagus. An additional scientific support program will establish primary tumor cells for better mechanistical understanding of the imaging biomarkers and testing of treatment according to targetable mutations.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 48
• Est. completion date: January 31, 2029
• Est. primary completion date: January 31, 2029
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• patients with squamous cell, undifferentiated or adenocarcinoma of the esophagus, UICC stage II-IVA (maximum T4a)

• ECOG performace status 0-2

• Complete clinical staging, including, esophagogastroscopy, EUS, CT neck/thorax/abdomen and adequate pulmonary function.

• Adequate hematological, renal, hepatic and pulmonary functions defined as:

granulocytes = 1.5 x 109/l platelets = 100 x 109/l total bilirubin = 1.5 x upper normal limit creatinine = 120 µmol/L FEV1 = 1.5 L

• Written, voluntary informed consent

• Willingness to perform effective contraceptive practices during treatment for patients with childbearing potential

Exclusion Criteria:

• Evidence of distant metastases (cM1)

• Prior high-dose radiotherapy to the thorax or abdomen

• Primary tumor cT4b

• history or concurrent malignancy as judged by the treating physician. This is only an exclusion criterion if the other malignancy is considered the oncological potentially leading cause of death compared to the esophageal cancer.
