Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with histology-confirmed primary truncal or extremity soft tissue sarcoma who are candidates for preoperative radiotherapy and limb-conserving surgery, have ECOG 0–3, and can tolerate anlotinib are appropriate.

Probably not a fit

Patients with excluded or benign histologies (for example DFSP or desmoid tumors), prior complete tumor resection, metastatic disease, or contraindications to anlotinib or severe organ dysfunction are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 2 interventional trial giving anlotinib hydrochloride concurrently with preoperative intensity-modulated radiotherapy (IMRT) for primary truncal or extremity soft tissue sarcoma. The protocol tracks safety, tumor response, local control, quality of life, and limb function after the combined treatment. Investigators will also explore whether anlotinib enhances radiosensitivity and correlate MRI imaging features with pathology and local control. The trial is conducted at the Cancer Hospital, Chinese Academy of Medical Sciences in Beijing and enrolls adult patients judged suitable for preoperative radiotherapy and limb-conserving surgery.

Why it matters

Potential benefit: If successful, the combination could shrink tumors before surgery, reduce local recurrence, and help preserve limb function.

How similar studies have gone: Combining anti-angiogenic TKIs with radiotherapy has shown activity in some sarcoma and other cancer settings, but preoperative IMRT plus anlotinib for extremity/trunk sarcoma is relatively novel and not yet widely validated.
