Assessment of TOPO2A as a Biomarker for Sensitivity to Doxorubicin or Doxil in Patients with Soft Tissue Sarcoma

Inclusion Criteria

• Patients must consent to providing tumor tissue prior to initiation of therapy if sufficient archival tissue is not available. The use of archival tissue is permitted. If a biopsy is required, the treating physician should ensure that this can be done safely
• Patients with STS will be eligible for the trial if their next planned chemotherapy will include single agent doxorubicin or Doxil. Patients who will be receiving concomitant therapy with olaratumab will be allowed to participate
• Sarcoma subtypes of angiosarcoma, epithelioid sarcoma, leiomyosarcoma, fibrosarcoma, myxofibrosarcoma, synovial sarcoma, pleomorphic rhabdomyosarcoma, undifferentiated pleomorphic sarcoma, liposarcoma (excluding well-differentiated) and malignant peripheral nerve sheath tumor will be included. These are subtypes for which a targeted therapy is not standard of care. All other subtypes will be included on a case by case basis as determined by the principal investigator
• Ability to understand and willingness to sign a written informed consent and Health Insurance Portability and Accountability Act (HIPAA) document
• Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria (at least one target lesion outside of previous radiation fields or progressed within a previous radiation field)

Exclusion Criteria

• Patients may not be receiving any other investigational agents, chemotherapy, radiation therapy or hormonal therapy (i.e. aromatase inhibitors for leiomyosarcoma)
• Any concomitant medical issue that in the opinion of the treating physician would confound survival from sarcoma (e.g. other active cancer, symptomatic brain metastases, cardiac conditions)
