Metastatic Leiomyosarcoma Biomarker Protocol

June 23, 2026 updated by: University of Michigan Rogel Cancer Center

Observational Study of Biomarkers of Disease-related Outcomes in Patients With Metastatic Leiomyosarcoma Receiving Chemotherapy

Leiomyosarcoma (LMS) is one of the most prevalent soft tissue sarcomas (STS) and can occur in various sites including soft tissue, uterus and retroperitoneal large vessels. Metastatic disease occurs in approximately 50% of patients diagnosed with leiomyosarcoma and prognosis is poor in setting of metastatic disease. A minority of patients benefit from treatment with chemotherapy and early biomarkers of benefit from treatment are lacking. A biomarker of tumor response and patient survival benefit from chemotherapy early in the course of chemotherapy would be of significant impact in treatment planning. Circulating tumor DNA (ctDNA) is present in blood of patients with advanced/metastatic cancer and may serve as biomarker of tumor response to chemotherapy. Blood samples will be collected prior to and during and chemotherapy, and analyzed for ctDNA and for mutations in genes that are associated with increased risk of developing sarcoma. Tumor tissue will be collected and analyzed for changes in genes. Digital images of the sarcoma from CT or MRI scans obtained during treatment will be obtained for advanced radiomic analysis. Study participants will be asked to complete a questionnaire on attitudes and understanding of genetics and genetic testing.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in ctDNA with RECIST
Time Frame: 4 years from study start
To examine the correlation of change in ctDNA with objective tumor response per RECIST. Analysis will occur at each subsequent early time-point (pre-cycle 1 and pre-cycle 2).
4 years from study start
Change in ctDNA with progression free survival (PFS)
Time Frame: 54 months from study start
To examine the correlation of change in ctDNA with progression free survival (PFS). Analysis of ctDNA will occur at each subsequent early time-point (pre-cycle 1 and pre-cycle 2). A Cox regression model will determine whether the baseline ctDNA levels are associated with PFS.
54 months from study start

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequency of ctDNA in patients with unresectable or metastatic leiomyosarcoma.
Time Frame: 4 years from study start
Plasma collections for ctDNA analysis will be collected at each subsequent early time-point (pre-cycle 1 and pre-cycle 2).
4 years from study start
