Fibrosarcoma

The ANTARES study is a phase II basket trial designed to evaluate the tissue-agnostic efficacy of the monoclonal anti-PD1 antibody, nivolumab, in patients with advanced or metastatic rare tumors. The study aims to treat rare malignancies with PD-L1 expression (CPS ≥ 10), regardless of the tumor's tissue type or location. Patients who have not responded to standard treatments will be included, and treatment will last for up to 12 months. The study will assess objective response, progression-free survival, and biomarkers such as PD-L1, ctDNA, and microvesicles, in a multicenter collaborative effort to provide innovative therapeutic options for this underrepresented population

This prospective, multi-center, randomized controlled study aims to assess the efficacy of utilizing 3D printed models in preoperative planning for the excision of tumors involving bony structures within the body. The study is expected to last approximately 12 months and involve up to 150 subjects across up to 5 sites. Subjects will be randomized in a 1:1 ratio into either the experimental arm, utilizing 3D printed models and imaging, or the active comparator arm, using only imaging. Primary endpoint: Operative time of surgical procedure. Secondary endpoints: Reduction of blood loss, proportion of postoperative adverse events, and negative tumor margins. Exploratory endpoints: Surgical planning ease, changes in surgical plan, and surgeon satisfaction.

This study will enroll patients with specific subtypes of unresectable or metastatic soft tissue sarcoma, and will combine tislelizumab with the standard chemotherapy of liposomal doxorubicin and ifosfamide to initially explore the efficacy and safety.

This study will evaluate the safety and efficacy of MASCT-I combined with Doxorubicin and Ifosfamide for first-line treatment in patients with advanced soft tissue sarcoma.

This phase III trial compares chest computed tomography (CT) to chest x-ray (CXR) for lung surveillance after curative-intent resection of high-risk truncal-extremity soft tissue sarcoma. Currently, complete oncologic resection (with or without radiation therapy) is the standard of care for most high-risk soft tissue sarcoma that has not spread to other parts of the body (localized). However, despite curative-intent resection, 20-40% of patients will develop cancer that has spread from where it first started (primary site) to other places in the body (distant metastases), with the lungs being the most common site. Thus, lung surveillance is important for detection of lung metastases in order to facilitate timely treatment. Although there is general agreement about the usefulness of postoperative surveillance, consensus is lacking regarding the optimal modality for lung surveillance after curative-intent resection for high-risk soft tissue sarcoma. Current National Comprehensive Cancer Network guidelines recommend chest imaging with CT or CXR every 3-6 months for 2-3 years, then every 6 months for the next two years, and then annually after that for high-risk tumors. Data from across the United States and internationally indicate that there is considerable variation in clinical practice with regards to the use of CXR versus CT chest for lung surveillance. The information gained from this trial may allow researchers to determine the effectiveness of varying imaging modalities needed for optimal surveillance for patients with extremity or truncal soft tissue sarcoma.
