In plain words

What the trial is, and whether it could suit you

* Leiomyosarcoma (LMS) is one of the more common soft tissue sarcomas (STS). * Patients presenting with large, high-grade, localized LMS are at significant risk of developing metastasis following curative surgery. * Clinical trials of neoadjuvant or adjuvant anthracycline and ifosfamide have suggested that patients with localized STS who are at high-risk of metastasis may benefit from chemotherapy, but the magnitude of benefit in unselected patient population is relatively small. * Currently, patient age, and tumor size and grade are used to assess risk of metastases and survival * Studies evaluating tumor response by imaging and histopathology have not established correlation between tumor characteristics as biomarkers for risk of metastasis or sarcoma recurrence. * Circulating tumor DNA (ctDNA) is present in blood of patients with advanced/metastatic LMS and may serve as biomarker of t
