Grand Rounds at Cedar Sinai Medical Center– January 19, 2017

Dr. Jabbari and XRO have been invited to hold Expert Speaker Grand Rounds on the Radiosurgery of the Spine at Cedar Sinai Medical Center in Los Angeles. This is scheduled for January 19th 2017 at 8:00 am.

John Wayne Cancer Center Grand Rounds – November 30, 2016

Grand Rounds on Spine Radiosurgery

The John Wayne Cancer Institute has invited Dr. Jabbari and XRO to give Grand Rounds on the new field of spine radiosurgery. This is an advanced and highly effective radiation technique for the treatment of difficult spine tumors, and not yet available at most institutions. Thanks to XRO's expertise, spine radiosurgery has been refined and available to our patients and referring physicians for the past several years. The Grand Rounds at John Wayne Cancer Institute is based on our recent academic publication on Spine Radiosurgery in the Cancer Journal, and will parallel Dr. Jabbari’s upcoming lecture at The Royal Australian and New Zealand College of Radiologists' 2016 Annual Scientific Meeting.

Global Grand Rounds – Save the Date and Program Details – September 29, 2016

Understanding The Need For MR-Conditional Cardiac Devices

Global Grand Rounds - Understanding The Need For MR-Conditional Cardiac DevicesDr. Jabbari has been asked to hold “Global Grand Rounds” on 9/29/16 for an international audience of primary care and subspecialty cardiac specialists on the topic of advanced imaging and therapy in oncology.

This is an important potential issue for patients requiring implantation of a cardiac device who have a subsequent cancer or other condition requiring MRI scans and/or advanced cancer therapy. This educational Grand Rounds will be via web-cast for the international audience. Click here for details.

XRO Co-Authors New Publication – July / August 2016

Stereotactic Body Radiotherapy for Spinal Metastases: Practice Guidelines, Outcomes and Risks

Stereotactic Body Radiotherapy for Spinal Metastases: Practice Guidelines, Outcomes, and RisksXRO has co-authored a new publication in press in The Cancer Journal on the complex and fast-advancing field of optimally treating cancers affecting the spine. This is a very common, difficult, and often debilitating condition affecting many thousands of cancer patients each year, with optimal care requiring highly sub-specialized expertise. Dr. Jabbari is the first author, in collaboration with other expert co-authors from major centers of excellence in the US and Canada. http://www.ncbi.nlm.nih.gov/pubmed/27441748

XRO Invited to Attend The Cancer Moonshot Summit in San Diego – June 29, 2016

Vice President Joe Biden is convening a Cancer Moonshot Summit, which will include conversations in communities across the United States. Dr. Jabbari will attend this summit on behalf of XRO and the Amtower institute.

Sanford Burnham Prebys Medical Discovery Institute (SBP), an NCI-designated Cancer Center, in La Jolla is one of 10 sites across the country chosen to co-host an official summit with the U.S. Department of Health and Human Services and The American Cancer Society Cancer Action Network.

These Summits are unique opportunities for researchers, advocates and survivors, and representatives from biotechnology and pharmaceutical companies to engage in the national charge to double the rate of progress toward a cure. Read the White House Fact Sheet.

Neuro-oncology Quarterly Report

Thanks to the tireless efforts of the radiation physics and therapy teams at Sharp Memorial / Amtower, cutting-edge and high-precision radiosurgery and radiation therapy technology is now fully commissioned and offered to neuro-oncology patients with complex malignancies of the brain and spinal column.

The Apex treatment systems allows for highly focused and conformal radiation therapy to complex tumors within the brain and spine, and within or near critical normal structures. The Hexapod system allows high-precision adjustments and accurate delivery of these highly focused beams to within ~ 1mm and ~1 rotational degree of spatial accuracy. The combination of these advanced technologies and the expertise of our team allow for highly effective treatment of such tumors, while minimizing risks, and advance the Laurel Amtower's xxxxxs anti-cancer armamentarium to new levels of excellence.

This international consortium of 4 centers of excellence will:

  1. Establish a multi-institutional consortium across high-volume linac-based Radiosurgery (SRS) centers.
  2. Generate a robust database of linac-based SRS.
  3. Conduct large-scale research focusing on projects that require a high volume of data gathered in a multi-institutional context.
  4. Validate best practices.
  5. Evaluate clinical outcomes that are relevant in the current era of cancer medicine.

Grant and Budget:

The grant and Statement of Work has been agreed between MGH and Elekta. Signatures of both parties are pending. The grant covers costs for 4 participating institutions to complete IRBs (up to $3,500 per site) and collect data (up to $5,000/ institution).

Proposed pre-database studies:

  1. Practice survey:
    1. Hypofractionation, single fractions, intact and cavities, single targets and multiple targets, timing of SRS post Surgery.
    2. Multiple centres: not just the consortium members.
