Stanford APBI Trial
Clinical Trial
Overview
Accelerated, partial breast irradiation (APBI) is a potentially important new way to incorporate radiotherapy in the treatment of women with breast cancer.
Currently, women with breast cancer who undergo a lumpectomy typically have 6 1/2 weeks of radiation to the entire affected breast after surgery. Accelerated, partial breast irradiation (APBI) changes this approach in two ways. It shortens the treatment time from 6 1/2 weeks to between 1 to 5 days, and reduces the treatment area from the entire breast to the area of the breast immediately around the lumpectomy site. This is the part of the breast where most cancers are likely to recur.
In many ways APBI is to current whole breast radiotherapy what a lumpectomy is to a mastectomy. The goal is to use a less invasive more focused treatment without compromising survival.
APBI has been used in limited trials in several hundred patients over the last 10 years. These trials show that in properly selected breast cancer patients APBI worked just as well as whole breast radiotherapy. In the initial studies, investigators relied on the placement of many catheters in the breast tissue (interstial brachytherapy). Newer techniques will hopefully provide the same good results but will deliver the radiation in faster and/or more convenient ways. This could increase interest in APBI and allow additional clinical trials that test the safety and effectiveness of the newer approaches. These newer approaches could increase quality of life for many women with breast cancer.
Investigators at Stanford University Medical Center are currently offering an IRB approved clinical trial that uses three new approaches for APBI. These three approaches are:
Intraoperative Radiotherapy (IORT) - 1 day
Intracavitary Brachytherapy (MammoSite) - 5 days
3-D Conformal/External Beam Radiotherapy - 5 days
The Stanford trial is led by Dr. Frederick Dirbas, Assistant Professor of Surgery, and by Dr. Donald Goffinet, Professor of Radiation Oncology. For further information about the trial please contact Janelle Maxwell or Triona Dolphin at (650) 498-7740.
COntrolled MyeloFibrosis Study With ORal JAK Inhibitor Treatment: The COMFORT-I Trial
This was a randomized, double-blind study comparing the efficacy and safety of ruxolitinib (INCB018424) tablets to matching placebo tablets in patients diagnosed with Myelofibrosis (either Primary Myelofibrosis (PMF) or Post-Polycythemia Vera Myelofibrosis (PPV-MF) or Post-Essential Thrombocythemia Myelofibrosis (PET-MF).
Stanford is currently not accepting patients for this trial.
