Bone and Soft Tissue Tumors

The goal of this observational study is to learn whether tumors of bone and soft tissue can be sorted into groups by their genes. Today these tumors are named mainly by how they look under a microscope. There are more than 150 names in use. The same tumor can be given different names by different doctors. The study includes people of any age with a bone or soft tissue tumor. All of them had tissue sampled at Karolinska University Hospital in Stockholm, Sweden. The main questions it aims to answer are: Can tests of a tumor's genes sort these tumors into clearer groups than the names used today? How often does a tumor's gene group differ from the name it was given at diagnosis? Can a computer program tell these groups apart from scanned pictures of the tissue? Researchers will compare the groups found by the gene tests with the diagnoses given at the time. They will also look at how each group did over the years that followed. This shows which way of sorting tumors better matches what happened to participants. Participants will not have extra visits, tests, or treatment for this study. The study does not change anyone's care. Researchers will: Use tumor tissue that was already taken as part of regular care Read the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) in the tumor, which carry its genetic instructions Read the chemical marks on the tumor's DNA that switch genes on and off Scan the glass slides of the tissue into digital pictures Collect facts about treatment and health from medical records Participants who are newly diagnosed will also be asked for a blood sample. Blood shows which gene changes a person was born with and which ones started in the tumor. If the study finds a gene change that matters for a participant's care, the study team tells the treating doctors through normal hospital routines.

This is a single-center, open-label phase II study of QL1706 for the treatment of advanced bone and soft tissue sarcomas.The study includes screening period, treatment period and follow-up period. Subjects will receive QL1706 5mg/kg iv every 3 weeks until disease progression or intolerance. Efficacy should be evaluated and safety will be monitored throughout the study.

DEEPLY aims to improve sarcoma therapy by the development of an innovative nanophotonic delivery approach to be applied in the future as an integrated local therapy for patients with inoperable tumors or with oligometastases. The major aim of the project is the development of innovative nanocarriers loaded with chemotherapeutic agents, whose delivery will be improved by the use of an optic fiber (optoporation). After the synthesis, and characterization of NPs, a prototype will be produced and preclinically validated on patient-derived biological material. This wide comprehensive methodological approach will ensure the obtainment of robust data to be faster exploited toward clinical applications.

The goal of this observational study is to learn how tumor tissue and blood samples from patients with sarcomas or metastases can be used to create laboratory models that help researchers study cancer behavior and test new treatments. Participants diagnosed with sarcoma or with bone or lung metastases from solid tumors will donate leftover tumor tissue and blood collected during their regular medical care. These samples will be used in the lab to build 3D models of the tumor, test drugs, and identify genetic and molecular markers. No treatments or procedures will be given as part of the study.

It is planned to prospectively collect, collate and report real-world clinical data of BSTS patients treated in our hospital in the next ten years to evaluate the changes in clinical characteristics, treatment patterns and survival information of these patients, in order to provide reference for clinical treatment and research of this type of tumor.
