Stanford APBI Trial

Clinical Trial

Overview

Intraoperative Radiotherapy (IORT) is one of three approaches used for accelerated, partial breast irradiation at Stanford.

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.

Efficacy of Oral Azacitidine Plus Best Supportive Care as Maintenance Therapy in Subjects With Acute Myeloid Leukemia (AML) in Complete Remission

This study enrolled 472 participants, aged 55 or older, with a diagnosis of de novo acute myeloid leukemia (AML) or AML secondary to prior myelodysplastic disease or chronic myelomonocytic leukemia (CMML), and who have achieved first complete remission (CR)/ complete remission with incomplete blood count recovery (CRi) following induction with or without consolidation chemotherapy.

The study is amended to include an extension phase (EP). The EP allows participants who are currently receiving oral azacitidine and who are demonstrating clinical benefit as assessed by the investigator, to continue receiving oral azacitidine after unblinding by sponsor until the participant meets the criteria for study discontinuation or until oral azacitidine becomes commercially available and reimbursed. In addition, all participants in the placebo arm and participants who had been discontinued from the treatment phase (irrespective of randomization arm) and continuing in the follow-up phase will be followed for survival in the EP.

Stanford is currently not accepting patients for this trial.

   study;

      - Participants randomized to oral azacitidine treatment arm and continuing in the
      treatment phase demonstrating clinical benefit as assessed by the investigator
      are eligible to receive oral azacitidine in the extension phase (EP);

      - Participants randomized into placebo arm of the study will not receive oral
      azacitidine in the EP, but will be followed for survival in the EP;

      - Participants currently in the follow-up phase will continue to be followed for
      survival in the EP;

   2. Participants who have signed the informed consent for the EP of the study;
