What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing if doing specific exercises can help people with soft tissue cancer in their arms or legs recover better and heal faster after surgery.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on high-dose steroid therapy or have had recent chemotherapy, you may not be eligible to participate.

Is pre-surgical exercise therapy safe for soft tissue sarcoma patients?

Moderate-intensity exercise (30-60 minutes a day) is generally safe after surgery for sarcoma patients, even when they are receiving additional treatments like chemotherapy or radiotherapy. However, the safety of exercise before surgery is not well understood, and more research is needed to determine its impact. ^{1 2 3 4 5}

How is Neoadjuvant Exercise Therapy different from other treatments for soft tissue sarcoma?

Neoadjuvant Exercise Therapy is unique because it involves physical activity before surgery to potentially improve outcomes, unlike standard treatments that typically focus on surgery, chemotherapy, and radiotherapy. This approach aims to enhance physical function and quality of life, which is not a primary focus of traditional treatments. ^{1 4 6 7 8}

I have blood flow problems in my limbs due to vascular disease.

I have had radiation or surgery on the tumor area before this study.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Neoadjuvant Radiation Therapy

Participants receive neoadjuvant radiation therapy (NRT) with or without an exercise regimen

10 weeks

Surgical Resection

Participants undergo surgical resection of the tumor

During surgery

Follow-up

Participants are monitored for wound complications and other outcomes post-surgery

24 weeks

What Are the Treatments Tested in This Trial?

Interventions

• Neoadjuvant Exercise Therapy

Trial Overview The trial is testing how pre-treatment exercise affects limb function and wound healing after surgery in patients with soft tissue sarcoma. Participants will engage in an exercise regimen before receiving standard care consisting of radiation therapy followed by surgical removal of the tumor.

How Is the Trial Designed?

Group I: Neoadjuvant Exercise Regimen Experimental Treatment 1 Intervention

Subjects will receive conventional NRT in conjunction with a prescribed exercise regimen during the usual 10-week duration of NRT treatment prior to tumor resection.

Group II: Control Active Control 1 Intervention

Standard of care: neoadjuvant radiation therapy (NRT).

Lower-extremities sarcoma patients should begin supportive rehabilitation and low-intensity physical activity after surgery to improve their quality of life, with a gradual increase in intensity during recovery.

Moderate-intensity resistance and endurance exercises (30-60 minutes per day) are safe for these patients post-surgery, even when undergoing adjuvant chemotherapy or radiotherapy, and a general goal of 150 minutes of combined exercise per week is achievable after 18-24 months of rehabilitation.

The Practice of Physical Activity in the Setting of Lower-Extremities Sarcomas: A First Step toward Clinical Optimization. Assi, M., Ropars, M., Rébillard, A.[2020]

In a study of 38 patients with soft tissue sarcoma, preoperative therapy, including neoadjuvant radiotherapy and chemotherapy, demonstrated effective local control with only 5.2% experiencing local recurrence after surgery.

The study showed that preoperative treatment was safe and feasible, with most patients undergoing limb-sparing surgeries, and the results suggest that lower limb involvement and marginal excision are associated with worse disease-free survival outcomes.

Neoadjuvant treatment of soft tissue sarcoma. Greto, D., Livi, L., Saieva, C., et al.[2021]

In a study of 66 patients with high-grade soft tissue sarcomas, those treated with neoadjuvant chemotherapy and preoperative radiotherapy showed promising long-term outcomes, with a 5-year overall survival rate of 71.2%.

Despite experiencing significant short-term toxicities (97% had grade 3 or higher), most of these resolved within a year, indicating that the treatment regimen, while harsh, can lead to favorable long-term results in high-risk cases.

The standard treatment for high-risk extremity soft tissue sarcomas (ESTS) typically involves a combination of surgery and radiation therapy, with chemotherapy sometimes added to improve outcomes.

This paper highlights the importance of chemotherapy and radiation therapy in reducing the risk of local or metastatic relapse in high-grade ESTs, suggesting that the pathological response to neoadjuvant treatment can provide valuable prognostic information.

What is the optimal (neo)adjuvant strategy of extremity high-risk soft tissue sarcomas (ESTS)? Kharmoum, S., Kharmoum, J., Chraibi, M., et al.[2023]

Preoperative chemotherapy has been shown to improve outcomes for certain pediatric sarcomas, leading to interest in applying similar strategies to adult soft tissue sarcomas, especially for tumors larger than 10 cm.

Despite the potential benefits of neoadjuvant chemotherapy in reducing the risk of recurrence and death, there is significant concern about the toxicity of these treatments and a lack of consensus on when they should be used in adult soft tissue sarcoma cases.

Chemotherapy: Does Neoadjuvant or Adjuvant Therapy Improve Outcomes? Canter, RJ.[2018]

In a study of 3422 patients with large high-grade soft tissue sarcoma, the addition of radiotherapy reduced the risk of death by 35% and chemotherapy by 24% compared to surgery alone, highlighting the importance of adjunctive therapies in improving survival rates.

Combining chemotherapy and radiotherapy resulted in a 5-year survival rate of 62.1%, significantly higher than the 51.4% survival rate for either treatment alone, indicating that these therapies work synergistically regardless of their sequencing or timing relative to surgery.

Preoperative radiotherapy (RT) significantly increases the rates of R0 resection (90.1%) in patients with extremity soft tissue sarcoma (STS) compared to postoperative RT (74.9%) and no RT (79.9%), based on a study of 27,969 patients.

Both achieving R0 resection and receiving RT (either pre- or post-operative) are linked to improved overall survival (OS), highlighting the importance of RT in surgical management of STS.

Neoadjuvant treatment significantly improves the integrity of the fibrous capsule surrounding soft-tissue sarcomas, with 76.9% of treated tumors showing intact capsules compared to only 35.1% of untreated tumors.

The study found that neoadjuvant therapies, especially combinations like chemotherapy and radiotherapy, not only enhance the capsular integrity but also increase the width of the fibrous capsule and reactive zone, suggesting a stabilizing effect on the tumor periphery that could influence surgical decisions.
