NCT06064682

Brief Summary

The purpose of this study is to examine if we can predict sensitivity of osteosarcoma to different chemotherapy agents using tissue cultures in the laboratory. We know that different chemotherapy agents can be used in the treatment, but not every sarcoma responds to them equally. It is important to understand if testing of the tissue obtained during a routine biopsy or surgery may be useful in selecting appropriate treatments. In addition, additional testing of the tumor, including genetic testing, will help us to understand osteosarcoma better.

Outcome Measures

Primary Outcomes (1)

  • organoids from initial biopsy

    To assess the feasibility of establishing organoids from initial biopsy and from postsurgical sample in patients with osteosarcoma, both in patients with localized disease and metastatic disease

    two years

Secondary Outcomes (3)

  • drug sensitivity of organoids

    two years

  • degree of necrosis in the tumor

    two years

  • clinical benefit

    two years

Study Arms (2)

Group 1: local tumor

patients with localized osteosarcoma who are scheduled to undergo diagnostic biopsy and are planned for surgical excision of the primary tumor

Other: standard of care biopsy

Group 2: metastatic disease

patients with metastatic osteosarcoma who are scheduled to undergo either biopsy or surgery of metastatic disease

Other: standard of care biopsy

Interventions

Image-guided or surgical biopsy of the lesion that is suspected to be osteosarcoma in a patient with localized disease (Group 1)

Group 1: local tumor

Study Population

Osteosarcoma is the most common primary bone malignancy of childhood and adolescence with a bimodal age distribution and a secondary peak in the 6th and 7th decades of life. The standard of care for localized disease is neoadjuvant cytotoxic chemotherapy followed by primary resection and adjuvant cytotoxic chemotherapy. Introduction of chemotherapy in the treatment of patients with osteosarcoma resulted in a significant improvement in the overall survival, but further improvement is needed. Currently, 5-year survival rate is 65 - 70%; for de novo metastatic disease or recurrent disease, 5-year survival rate is \<30%. Recurrent or metastatic osteosarcomas are usually resistant to standard of care, and treatment options for refractory osteosarcomas are extremely limited.

You may not qualify if:

  • \- Patients without diagnosis of osteosarcoma and whose imaging studies are suggestive of osteosarcoma and who are planned to undergo biopsy or surgery for diagnostic purposes
  • \- Patients whose imaging studies are suggestive of metastatic osteosarcoma and who are planned to undergo biopsy or surgery for diagnostic purposes
