About

This study aims to investigate the value of 68Ga-grazytracer in predicting the efficacy of immunotherapy for advanced soft tissue sarcomas.

Full description

The investigators will number all participants, create a medical record file, and record their basic information (gender, age) as well as contact information and medical history information. All participants will undergo a 68Ga-grazytracer PET/CT after 3 cycles of immunotherapy to evaluate response. The imaging response measurements will be compared with the histopathological or clinical assessment results as gold standard.

Enrollment: 40 estimated patients

Sex: All

Ages: 6 to 80 years old

Volunteers: No Healthy Volunteers
