Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

"Blood and Tissue Extraction for Immunological Examinations During Neoadjuvant Therapy of Soft Tissue Sarcoma" is a prospective study with additional translational research using preoperative and postoperative tissue, blood sampling and advanced imaging.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All patients (\> 18 Years) with histologically confirmed high-risk soft tissue sarcoma eligible for neoadjuvant multimodal therapy (including radiotherapy +/- concomitant and sequential chemotherapy +/- hyperthermia as well as surgery) are screened for the study. Neoadjuvant therapy consists of 50-50.4 Gy in 25-28 fractions. Additional concomitant or sequential chemotherapy may be applied in selected cases (young patients, high-grade tumors). Additional hyperthermia concomitant to neoadjuvant radiotherapy is applied in selected cases if not contraindicated.

Preoperative tissue sampling to generate primary tumor cell lines in additional translational research is performed in each patient with a lesion suspect for soft tissue sarcoma and eligible for multimodal therapy. Primary cell lines are analyzed biologically (growth pattern, radioresistance, migration, molecular markers RT-PCR, immunological properties such as immunogenic cell death, lysis by cellular immunotherapies such as CAR-NK cells. Postoperative tumor tissues are additionally analyzed for immune cell mapping using complex immunohistochemistry. Biopsy and resection should include proteome analysis and DNA sequencing (only of the tumor tissue, not normal tissue).

Additional immunological monitoring (including cellular immune status, serum marker e.g. cell free DNA, HMGB1) is performed using blood sampling with in total 4 blood controls (25 ml each, before neoadjuvant radiotherapy, during the second and last week of radiotherapy as well as before surgery). In patients treated with concomitant MR-guided hyperthermia, weekly MR-imagine is performed.

Follow-up is carried out as part of the oncological controls over 5 years. The overall study is planned over a period of 5 years (interventional part), additional 5 years follow-up period.
