Stereotactic Pelvic Adjuvant Radiation TherApy in Cancers of the UteruS

Official Title

Stereotactic Pelvic Adjuvant Radiation TherApy in Cancers of the UteruS): A Phase I/II Study (SPARTACUS)

Summary:

Advanced technology has enabled radiation oncologists to more accurately and precisely target radiation to areas at risk while maximally sparing healthy tissue. A secondary result of these technologic advances has been the increased utilization of hypofractionationed treatment protocols, since the combined ability to better visualize and precisely deliver radiation to target volumes has allowed radiation oncologists to leverage the therapeutic ratio toward higher target doses whilst maintaining safe doses to the pertinent organs-at-risk. The spectrum of hypofractionation ranges from what are considered moderate (ie. 2- 5 Gy / fraction) into the realm of what is more commonly referred to as stereotactic body (SBRT), generally >5 Gy / fraction. There is growing evidence demonstrating both safety and efficacy for SBRT. The investigators propose that these advantages are translatable to the adjuvant treatment of endometrial cancer. The investigators submit that a prescription dose of 30 Gy in 5 fractions. Through precision delivery and careful dosimetry the treatment should be safe and well tolerated with minimal impact on patient quality of life.
