Preoperative vs Postoperative IMRT for Extremity/Truncal STS

February 15, 2024 updated by: Mount Sinai Hospital, Canada

Phase III Study of Preoperative vs Postoperative Intensity Modulated Radiation Therapy For Truncal/Extremity Soft Tissue Sarcoma

This study is designed to determine if preoperative image guided radiation therapy (IGRT) delivered using intensity modulated radiation therapy (IMRT) followed by surgery results in similar short-term wound healing complications as surgery followed by postoperative IGRT in patients with extremity or truncal soft tissue sarcoma. Half of the patients will receive preoperative radiotherapy, half will receive postoperative radiotherapy.

Detailed Description

Perioperative RT in addition to surgery is widely accepted as standard management for soft tissue sarcoma (STS) of the extremity and trunk. However, controversy remains as to whether RT should be delivered preoperatively or postoperatively. While both confer similar rates of local control, preoperative RT leads to a decrease in late tissue morbidities such as fibrosis, limb edema, joint stiffness and fracture as compared to postoperative RT. The reasons for this are likely multifactorial, but are in part related to total dose delivered (50 Gray (GY) preoperatively and 60-66 Gy postoperatively) and, based on a previous National Cancer Institute (Canada) Phase III randomized controlled trial, the much larger volume treated in the postoperative setting compared to that in the preoperative setting. The optimal radiation dose used in the postoperative setting is unknown but has been developed empirically and doses of 60-66 Gy are generally employed.However, investigators in Norway/Sweden and France have found equivalent local control rates for patients with negative surgical margins treated with 50 GY postoperativelyThe main concern with preoperative RT has centered on the risk of an increased rate of delayed wound healing and major wound complications. Although some studies suggest it may be possible to reduce the incidence of acute wound healing complications associated with pre-operative radiation than previously seen in the 2D RT era, this has yet to be tested in the phase III setting. IG-IMRT allows a much higher degree of conformality and accurate delivery of dose to the tumour while sparing surrounding normal tissue. This may allow similar rates of acute wound healing complications for pre- and postoperative RT in the treatment of STS.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

  • Deep wound packing required at any time (deep packing defined as packing deep to dermis in an area of dehisced wound) to an area of the wound measuring at least 2 cm in length;
  • Prolonged dressing changes, including packing of the wound for greater than six weeks from wound breakdown;
  • Repeat surgery for revision of a split thickness skin graft or requirement for wet dressings for longer than four weeks. (It is permissible for a patient to protect a totally epithelialized skin graft with a dry dressing without declaring a major wound complication)
