High-Risk Localized Soft Tissue Sarcoma
Conditions
Brief summary
This is a prospective, single-center, single-arm, phase Ib/II clinical trial. The study aims to evaluate the safety and efficacy of the treatment which combines radiotherapy, chemotherapy and immunotherapy in patients with high-risk localized soft tissue sarcoma. There will be 52 patients with high-risk localized extremity and trunk soft tissue sarcoma recruited. The trail is designed as a two-stage study. In safety lead-in phase (phase Ib), using 3+3 design, 4 cycles of Pegylated Liposomal Doxorubicin (37.5 mg/m2, 30 mg/m2, q3w) or doxorubicin hydrochloride (75mg/m2, q3w), Sintilimab (200mg, q3w) and radiotherapy (BED=50-60Gy (α/β=10)) will be applied. In phase II, Pegylated Liposomal Doxorubicin will be applied in the recommended phase 2 dose (RP2D) according to phase Ib. And 200mg sintilimab and radiotherapy will be applied as before. The dose-limiting toxicity (DLT) in phase Ib and objective response rate (ORR) in phase Ib+Phase II will be mainly analyzed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | The objective response rate (ORR) will be evaluated before surgery, which will be scheduled 5-12 weeks after the last fraction of radiotherapy. | The percentage of patients with objective response. Objective response is defined as complete response (CR) or partial response (PR) per response evaluation criteria (RECIST v1.1) before surgery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pathological Complete Response (pCR) and Near pCR Rate | The pathologic complete response (pCR) rate will be evaluated from surgical samples, immediately after surgery. | The proportion of subjects whose pathological response rate of tumor tissue in postoperative specimens is ≥90% after preoperative treatment. |
| Non-Perfused Volume (NPV) | The non-perfused volume (NPV) will be measured in four weeks before preoperative treatment and before surgery, which will be scheduled 5-12 weeks after the last fraction of radiotherapy. | The changes in tumour volume that are not enhanced in imaging images with contrast agent before and after treatment. |
| Acute Adverse Events | through study completion, an average of 6 months. | The toxic reactions are evaluated and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Edition 5 (NCI-CTCAE V. 5). |
| Wound Complications | Up to 120 days from the surgery. | Postoperative incision healing, with reference to the Canadian study for grading of wound complications. |
| Local Control Rate | Up to 5 years | The proportion of subjects who recurred within the radiotherapy exposure field from initiation of treatment to the imaging assessment of all evaluable subjects. |
| Progression-Free Survival (PFS) | Up to 5 years | The time from initiation of treatment to PD or death from any cause. |
| Overall Survival (OS) | Up to 5 years | The time from initiation of treatment to death from any cause. |
| Quality of Life (QoL) according to the Musculoskeletal Tumor Society (MSTS) | Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery. | The Musculoskeletal Tumor Society (MSTS) is a measure of physical function across 7 items, including pain, range of motion, strength, joint stability, joint deformity, emotional acceptance, and overall function. Each item is scored from 0(worst) to 5(best) with a maximum possible score of 35, which is converted to a scale from 0 to 100 points. |
| Quality of Life (QoL) according to the Toronto Extremity Salvage Score (TESS) | Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery. | The Toronto Extremity Salvage Score (TESS) is a self-administered questionnaire evaluating possible limitations in physical activity. A total of 30 questions are included in the TESS, and the degree of disability is rated from 0 (complete disability) to 5 (no functional impairment) in each item. |
| Quality of Life (QoL) according to the Short Form (SF)-36 questionnaires | Quality of Life (QoL) will be evaluated at least five times: before treatment, at 3, 6, 12 and 24 months respectively after surgery. | The Short Form (SF)-36 questionnaires is a 36-item health survey status which is composed of the following eight domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Each of these domains can be rated from 0 (worst) to 100 (best). The final SF-36 score is converted to a 0-100 points range scale. |
