Development of Innovative Preclinical Ex Vivo Models for the Study of Sarcomas and Metastases From Solid Tumors

This study is creating laboratory models from actual patient tumor tissue (sarcomas and bone/lung metastases from solid tumors) to better study how these cancers behave and respond to treatments outside the body. These 'ex vivo' models can help researchers develop better therapies without testing on patients directly. **You may be eligible if...** - You are between 0 and 85 years old - You have been diagnosed with a sarcoma (a type of connective tissue cancer) or have bone or lung metastases from another solid tumor cancer - Sufficient tumor tissue or blood samples can be collected during your planned procedure - You have signed the required informed consent for tissue/blood use in research and biobanking **You may NOT be eligible if...** - Your diagnosis is not a sarcoma or metastases from a solid tumor - You have not signed the required consent forms Talk to your doctor to see if this trial is right for you.
