Purpose
The efficiency of T cell based immunotherapies is affected by the insufficient migration and activity of tumor specific effector T cells in the tumor. Aim of this phase I/II clinical trial is to evaluate whether a neoadjuvant, low dose radiotherapy can improve T cell connected anti tumor immune response in colorectal liver metastases.
The primary endpoint is the number of tumor infiltrating T cells. Furthermore the T cell activity in situ, the number of regulatory T cells and the frequency of tumor reactive T cells in the blood and bone marrow will be examined.

| Official Title: | Randomised Controlled Phase I/II Trail to Evaluate the Effect of Neoadjuvant Radiation on Tumor Infiltrating T-cells by Low Dose Radiation Therapy in Resectable Colorectal Liver Metastases Patients |
- Purpose of the study is the determination of an active local external beam radiotherapy dose leading to a maximal number of tumor infiltrating T-cells. The total T-cell activity serves as primary surrogate parameters for anti- tumor activity [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- To determine local control and recurrence patterns of colorectal liver metastases in a CT [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- To determine the progression-free survival in patients treated with low dose photon beam radiation therapy [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- • To determine the surgical morbidity in patients undergoing liver resection who received this protocol treatment [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- • To determine 30-day post-operative mortality after liver resection in patients who received this protocol treatment [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- • To determine the T-cell activity in the resected liver tissue [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- • To determine quality of life according to the EORTC QoL questionnaire after 6 months. [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- To determine the number of regulatory T-cells in the resected liver tissue [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To determine the frequencies of tumor-reactive T-cells in the blood and bone marrow of the patients [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To determine quality of life according to the EORTC QoL questionnaire after 12 months. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- To determine the number of patients with adverse events as a measure of safety and tolerability according to CTCAE, Version 4.0 criteria [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
