Phase I/II Trial of Pre-Operative Image Guided Intensity Modulated Proton Radiation Therapy (IMPT) or Photon (IMRT) With Simultaneously Integrated Boost to the High Risk Margin for Retroperitoneal Sarcomas
This research study is a Phase I clinical trial. Phase I clinical trials test the safety of
an investigational intervention. Phase I studies also try to define the appropriate dose of
the investigational therapy to use for further studies. "Investigational" means that the
intervention is still being studied and that research doctors are trying to find out more
about it.
Retroperitoneal sarcomas are soft tissue tumors located at the far back of the abdomen.
Typically, patients with retroperitoneal sarcomas either have surgery for the removal of
their tumors alone, or have their tumors removed, followed by standard radiation therapy, or
have pre-operative radiation followed by surgery. When conventional radiation therapy is
delivered after surgery, it can damage normal tissue. In this study, you will undergo proton
beam radiation therapy or IMRT before undergoing surgery for the removal of your tumor.
Proton radiation and IMRT are FDA approved radiation delivery systems. Protons are tiny
particles with positive charge that can be controlled to travel a certain distance and stop
inside the body. In theory, this allows better control of where the radiation dose is
delivered as compared to photons. Since proton radiation is more targeted, it may help to
reduce unwanted side effects from radiation.
In this study, a standard dose of radiation will be given to the majority of the tumor, while
a simultaneously integrated boost of additional radiation will be given to certain areas of
the tumor identified as higher risk. This means that a higher radiation dose will be given to
the higher risk areas of the tumor.
The purpose of this study is to determine the highest dose of radiation therapy with protons
or IMRT that can be delivered safely in patients with retroperitoneal sarcomas and the
effectiveness of proton beam radiation therapy as an intervention for patients with
retroperitoneal sarcomas.

While being screened to determine eligibility for this study you may choose to participate in
an additional blood sample for circulating DNA and a genomic DNA sample.
Since we are looking for the highest dose of Radiation Therapy that can be administered
safely without severe or unmanageable side effects in participants that have retroperitoneal
sarcomas, not everyone who participates in this research study will receive the same dose of
study therapy. The dose you get will depend on the number of participants who have been
enrolled in the study before you and how well they have tolerated their doses. Your study
doctor will tell you which dose you will get.
Radiation planning is standard of care for all patients undergoing radiation therapy. Before
you begin radiation therapy you will have a radiation planning CT scan of the tumor site.
This scan will be in addition to the scans done in order to confirm your eligibility for this
study. Doctors will use teh images from this scan to plan your radiation treatment.
You will receive radiation therapy every day Monday through Friday for about six weeks. You
will receive study therapy as an outpatient. During radiation therapy, you will be seen by
the study doctor once a week. Each visit will take about 15 minutes, and the following
assessments will be completed: medical history, vital signs, body weight and assessments for
any side effects you may be experiencing.
After the final dose of radiation therapy you will be assessed for side effects of radiation
following your last dose and before surgery. The following assessments will be completed
before your surgery at this visit: Chest CT, CT/MRI of the abdomen/pelvis and routine blood
tests to check for overall health.
You will be seen for a follow-up visit within one month of discharge following surgery and
again four months after the surgery. At the first follow-up visit, the following assessment
will be completed: medical history, vital signs and body weight, questions about side effects
and routine blood tests to check for overall health. At the four month follow up visit the
following assessment will be completed: medical history, vital signs and body weight, chest
CT and abdominal/pelvic CT.
After your four month follow-up visit, you will be seen twice yearly following radiation for
the first five years and then once a year for the rest of your life.
