Preoperative treatment for soft tissue sarcoma using radiation and Fluzoparib

Preoperative Moderately Fractionated Intensity-modulated Radiotherapy (IMRT) With/Without Concurrent Fluzoparil for Locally Extremity or Trunk Sarcoma

Phase 2 Interventional Cancer Institute and Hospital, Chinese Academy of Medical Sciences · NCT05938374

This study is testing if a combination of radiation therapy and a new drug called Fluzoparib can help improve treatment outcomes and quality of life for people with soft tissue sarcoma before surgery.

What this trial studies

This study investigates the safety and efficacy of preoperative moderately fractionated intensity-modulated radiation therapy (IMRT) combined with Fluzoparib Hydrochloride for patients with primary truncal or extremity soft tissue sarcoma. The trial aims to evaluate the quality of life and extremity function following this combination treatment, as well as to explore the mechanisms by which Fluzoparib enhances the effects of radiation. Additionally, the study will assess the correlation between MRI imaging, pathological findings, and local control of the disease.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with histologically confirmed soft tissue sarcoma of the trunk or extremities who are suitable for preoperative radiotherapy and conservative surgery.

Not a fit: Patients with contraindications to Fluzoparib or those with specific types of sarcoma like dermatofibrosarcoma protuberans may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and quality of life for patients with soft tissue sarcoma.

How similar studies have performed: While the combination of radiotherapy and PARP inhibitors is being explored, this specific approach is novel and has not been extensively tested in prior studies.
