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.
N2007-02:Bevacizumab,Cyclophosphamide,& Zoledronic Acid in Patients W/ Recurrent or Refractory High-Risk Neuroblastoma
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Zoledronic acid may stop the growth of tumor cells in bone. Giving bevacizumab together with cyclophosphamide and zoledronic acid may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects of giving bevacizumab together with cyclophosphamide and zoledronic acid in treating patients with recurrent or refractory high-risk neuroblastoma.
Stanford is currently not accepting patients for this trial.
Stanford Investigator(s):
Intervention(s):
- drug: Bevacizumab
- drug: cyclophosphamide
- drug: zoledronic acid
Eligibility
Inclusion Criteria:
- Patients must be no more 30 years of age when enrolled on study.
- Patients must have relapsed neuroblastoma, refractory neuroblastoma that had less than
a partial response to standard treatment or persistent neuroblastoma that had at least
a partial response to standard treatment.
- Patients who have at least a partial response to standard treatment who still have
neuroblastoma that can be seen on CT/MRI or MIBG scans must have a surgical biopsy
done of the tumor to confirm that it is neuroblastoma. Patients with relapsed or
refractory neuroblastoma do not need to have a biopsy done to enter on study.
- Patients must have adequate heart, kidney, liver blood clotting and bone marrow
function. Patients who have bone marrow disease must meet the bone marrow function
criteria to enter the study.
- Patients must have recovered from all prior chemotherapy and surgical procedures
Exclusion Criteria:
- They are known to be sensitive to Bevacizumab.
- They have a history of very high blood pressure which required intensive intervention
- They are pregnant or breastfeeding
- Neuroblastoma is present in the brain on a CT or MRI scan done at study entry.
Patients with neuroblastoma found in the bones of the skull are eligible if there is
no tumor mass associated with them pressing on the brain.
- They have a history non healing wounds
