PRESTO Trial Summary

This trial is investigating whether a shorter, more intensive course of radiation therapy before surgery is as effective as the standard course of radiation therapy for people with soft tissue sarcomas.

Who is the study for?
This trial is for adults over 18 with a specific type of cancer called soft tissue sarcoma, located above the knee or in the trunk. Candidates must have a tumor that can be surgically removed, no prior radiation therapy, and an ECOG score of 0-2 indicating they are relatively active. They cannot participate if they have other cancers (except certain skin cancers), lymph node involvement by cancer, previous radiation in the area to be treated, or major illnesses.Check my eligibility
What is being tested?
The study is testing hypofractionated radiotherapy as pre-operative treatment for soft tissue sarcomas. This approach uses larger doses of radiation per session but fewer sessions overall compared to traditional methods. The goal is to deliver a higher effective dose more quickly and potentially reduce delays before surgery and wound complications.See study design
What are the potential side effects?
Potential side effects from hypofractionated radiotherapy may include skin irritation at the treatment site, fatigue due to high doses of radiation, swelling or pain around the affected area, and possibly delayed wound healing post-surgery.

I am 18 years old or older.
My doctors agree I should have radiation and surgery before other treatments.
I am available for treatment and follow-up appointments.
My cancer is either new or has come back in the same area, and I haven't had an accidental removal of it.

PRESTO Trial Design

1Treatment groups
Experimental Treatment
Group I: Experimental : Short Course Pre-operative RadiothErapyExperimental Treatment1 Intervention
As part of the planning process, you need to undergo a CT Simulation.It is special type of CT scan used to measure and design the radiation fields to precisely target the tumor.It is done at the Radiation Oncology Department at the MUHC. Some patients may be asked to also undergo an MRI Simulation, and the CT simulation. You may asked to provide a blood sample to ensure good kidney function prior to the CT and MRI scans. Both CT and MRI simulations are considered standard of care. Once the simulation studies are done, there is about a 2 week waiting period for radiation planning prior to starting the radiation treatments. The hypofractionation technique will be delivering five fractions (one fraction delivered every 2nd day) of 7 Gy daily of external beam radiotherapy (EBRT) over a period of one and half weeks for a total of 35 Gy. The treatment should last approximately 30 minutes. Once treatments are done, there is a 4 to 6 week wait for surgery.
