Trial summary

When treated with surgery alone, many soft-tissue sarcomas have a high chance of coming back. Radiation therapy is frequently used in addition to surgery to reduce the chances of the sarcoma coming back. Read more about this study

About this study

When treated with surgery alone, many soft-tissue sarcomas have a high chance of coming back. Radiation therapy is frequently used in addition to surgery to reduce the chances of the sarcoma coming back. However, radiation can have long-term side effects on the normal tissues surrounding the tumor, leading to problems such as swelling, scarring, and joint stiffness.

Recently, there have been advances in the way that radiation therapy can be given. Proton radiation therapy is one of those advances. With proton radiation, it is possible to give radiation over a smaller area surrounding the tumor, resulting in less radiation to the surrounding normal tissues.

The purpose of this study is to determine whether proton radiation decreases the long-term side effects of radiation on normal tissues and if smaller proton radiation fields reduce local recurrence compared to the larger radiation fields that have been used in prior studies.

Read the detailed description

Data support preoperative radiotherapy as one of the standard options in the management of large or high-grade extremity soft tissue sarcomas (STS). The advantages of preoperative radiotherapy are lower doses and smaller radiation volumes; these may be used to effect improvement of long-term side effects and extremity function. Another potential advantage is assisting surgery through tumor shrinkage and reduction of tumor cell seeding. The disadvantage of preoperative radiation is the higher likelihood of postoperative wound complications, but in a prospective phase III trial these complications were found to be generally temporary and without significant effect on long term function.

Combined conservative surgery and radiotherapy has shown to achieve excellent local control in sarcoma patients following margin-negative surgery, but late radiation morbidity and reduced quality of life may result from adjuvant radiation. The dosimetric advantage of proton radiotherapy may translate into reduced acute and late effects due to improved normal-tissue sparing in the treatment of extremity and truncal STS. However, these potential advantages need to be validated in clinical trials. The investigators propose a phase II study to evaluate the effect of preoperative proton radiotherapy on the reduction of late radiation morbidity, patterns of failure, and impact of late radiation morbidity on general quality of life (QOL).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • proton radiationRadiation

    Also called Proton radiotherapy, Proton treatment

    proton radiation: 2 GyE/Day to isocenter, one treatment per day, 5 days per week for 25 treatments (=50 GyE to isocenter/25 fractions)

  • surgery (wide local excision; limb preservation surgery)Procedure or surgery

    Also called wide local excision, limb preservation surgery

    In areas with ample soft tissue that can be removed without compromising future function or wound closure, wide margins is the goal of treatment; associated rates of local failure are low in such instances. Margins will be determined by the surgeon; the goal is to achieve at least a 2 mm negative margin resection. However, smaller margins can be acceptable if it allows for limb-sparing surgery with conserved functional outcomes. Every effort will be made to have limb preservation surgery unless there is documented evidence of tumor progression during or after the course of radiation that would require amputation for an appropriate margin resection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Late Radiation Toxicities at 2 Years From the Start of Radiation Treatment

    To report the number of participants with late radiation morbidity

    Late subcutaneous fibrosis and joint stiffness are assessed using the European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group (EORTC/RTOG) late toxicity scoring criteria below:

    Subcutaneous tissue: Grade 1(slight fibrosis; subcutaneous fat loss), Grade 2(moderate fibrosis: slight field contracture), Grade 3(severe fibrosis; field contracture >10%), Grade 4(necrosis), Grade 0 (none) Joint stiffness: Grade 1(mild stiffness; slight range of motion loss), Grade 2(Moderate stiffness, pain, range of motion loss), Grade 3(Severe stiffness, pain, range of motion loss), Grade 4(necrosis; complete fixation), Grade 0 (none) Lymphedema is measured according to the criteria of Stern: Score 0(none), Score 1(Mild but definite swelling), Score 2(Moderate), Score 3(Severe, considerable swelling), Grade 4(Very severe (skin shiny \& tight)

    Measured: at 2 years from the start of radiation treatment

Secondary outcomes (5)
  1. Grade 3-5 Adverse Events at 6 Months From the Start of Radiation Treatment.

    This study will utilize the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 for reporting of adverse events.

    Measured: 6 months

  2. Patterns of Failure at 6 Months From the Start of Radiation Treatment

    Prespecified patterns of failure, including local failure, regional failure, distant failure, and death without disease progression at 6 months from the start of radiation treatment measured by CT or MRI scan

    Measured: 6 months

  3. Patterns of Failure at 6 Months

    Patterns of failure including local failure, distant failure, distant-disease-free survival, disease-free survival, overall survival rates, and second primary tumor at 6 month from the start of radiation treatment on CT or MRI scan.

    Measured: 6 months

  4. Wound Complication Rates Infection, Dehiscence at 6 Months From the Start of Radiation Treatment.

    Wound complications - Major wound complications, such as secondary operations, re-admissions, and/or invasive procedures for wound complication (deep wound packing and/or prolonged dressing changes) due to Infection, dehiscence.

    Measured: 6 months

  5. Report of Late Radiation Morbidity at 2 Years

    To report the number of participants with late radiation morbidity using quality of life survey including physical, emotional, social/family and functional well-being.

    Measured: at 2 years
