Volume 2, Issue 2 Spring/Summer 2017

Dear Friends and Colleagues,

It has been an eventful year for Radiation Oncology. There have been recent changes,

beginning with the appointment of Dr. Steve Lee as our new interim Residency Program Director effective September. Dr. Lee previously served as Program Director for UCLA Radiation Oncology residency and Medical Director of Long Beach VA Radiation Oncology. He brings tremendous vision and resources that will help maximize our Department’s potential.

We recently bid farewell to Dr. Hanako Farol, who relocated to Kaiser Permanente LA, as well as our graduates Drs. Daniel Bourgeois, Randy Wei, Samir Laoui, and Mr. Alfredo Banda. We welcome our new residents, Drs. Pericles Ioannides (PGY-2) and Wenbo Wei (physics).

Our faculty remain active in scholarly activity. Dr. Varun Sehgal served as an ABR Medical Physics oral examiner in Louisville, KY, in July. As President of the Radiation Research Society, Dr. Charles Limoli will be the first to bring their annual meeting to Latin America in October, where Dr. Munjal

Acharya will also be presenting. And once again, our department will be well-represented at the American Society for Radiation Oncology (ASTRO) meeting in September and the Radiosurgical Society Meeting in November.

Faculty and residents from all teaching sites (UCI, LB Memorial, LBVA) convened at another successful Biennial Meeting at LBVA in May. These meetings allow us to align our goals and objectives in the best interests of our residency. We look forward to our next meeting in Fall, which will be hosted right here at UCI.

We hope you enjoy reading this newsletter and we welcome your comments. We thank our patients, colleagues, and alumni for supporting us in our long term goal of providing Orange County and Southern California with the most advanced radiation therapy technology and world class care.

Sincerely, Nilam S. Ramsinghani, M.D. Chair and Clinical Professor Department of Radiation Oncology

Robert Sanford, Ph.D., MBA Chief of Physics—Radiation Oncology University Medical Center, New Orleans

After completing my residency in 2001 and working as a junior faculty at UCI, I made the difficult decision to move to Tulane University Cancer Center in New Orleans to initiate the first IMRT

program in the region. Since UCI was one of the first centers in the U.S. to offer IMRT, my residency provided me great training in what was then a cutting-edge treatment modality. Along with Tulane clinical duties, I was simultaneously providing physics services at the nearby state-owned Charity Hospital and working on the clinical implementation of an early Monte Carlo radiation dose calculation algorithm.

Everything came to a crashing halt in 2005 when Hurricane Katrina slammed into the Gulf Coast and the New Orleans levee system failed. Like much of the city, Tulane and Charity hospitals flooded. The ground floor of Tulane Cancer Center took on 1 to 2 feet of water, while Charity’s department - housed in the basement - was completely submerged.

Tulane relocated its cancer services to an abandoned radiation therapy facility about 40 miles north of New Orleans. Trailers were brought in and furnished with chemotherapy chairs, and I led the effort to revive the abandoned radiation equipment. Then all efforts concentrated on redesigning and refurbishing the downtown campus. About 1 year after flooding, Tulane Cancer Center reopened in its original New Orleans location.

A new $1.1 billion University Medical Center (UMC) New Orleans facility now replaces the former Charity Hospital. Until June of this year, I served as Chief of Physics at both UMC and Tulane, when I moved to UMC fulltime. The new facility is keeping me quite busy with research and planning of a recently announced $70 million proton center addition.

I cannot overstate the value of my physics residency at UCI. My training and experience there continue to serve me well to this day, and I always think very fondly of the people and my time there.


Achieving Precision Radiotherapy with DIBH

Varun Sehgal, Ph.D. Clinical Professor

The Department of Radiation

Oncology employs the Deep

Inspiration Breath Hold (DIBH)

technique for delivering external beam

radiation therapy to patients with left-

sided breast cancers. The underlying

rationale for this approach is that by

taking a deep breath, the heart is

pushed away from the left breast.

Thus, delivering the radiation while

the patient is maintaining a deep

inspiration breath hold leads to

reduced radiation dose to the heart,

potentially resulting in fewer long-

term cardiac complications. At UC

Irvine Radiation Oncology, this is

accomplished using the Align-RT

system (Fig. 1).

Align-RT employs three cameras to

perform real-time 3D tracking of the

patient’s surface. The cameras

monitor thousands of points on the

patient’s skin, and can detect any

motion as the patient holds their

breath, with sub-millimeter accuracy.

The system will automatically detect if

the patient moves out of position or

the patient is unable to hold their

breath, and the radiation is turned off

instantly. A preliminary review of our

patient data has shown

a significant decrease

in both the mean heart

radiation dose as well

as the maximum heart

radiation dose. This

novel data was

presented by our

residents and faculty at

our annual ASTRO

meeting (D. Bourgeois,

P. Daroui et al.,

“Dosimetric Comparison

of Deep Inspiration Breath Hold and

Free Breathing Treatment Techniques

for Left-sided Breast Cancer using 3D

Surface Tracking” Presentation at The

Annual Meeting of American Society

of Radiation Oncology (ASTRO), Sept.

2016, Boston, MA), and is in the

process of publication. Patient

compliance has been good and

treatment delivery times have also

been clinically acceptable.

With additional contribution by M. Al-Ghazi,

PhD and P. Daroui, MD PhD.

Muthana Al-Ghazi, Ph.D. Clinical Professor & Director of Medical Physics

Earlier this year we

said good bye to

our former physics

resident, Dr. Samir

Laoui. He

completed the

program and

obtained a position in Missouri in

private practice with a group headed

by Carlos Perez’ daughter. Shortly

thereafter, we welcomed Dr. Wenbo

Wei to fill the vacancy left by Samir.

Wenbo comes to us from Ohio State

University where he had been a

postdoctoral fellow in MRI imaging

research.

The physics residency program is

coming up for its 10th year

accreditation cycle. Hard to believe!

The application was submitted in a

timely fashion thanks to the help of

Dr. Varun Sehgal and Michelle Leung.

We are looking forward to the site

visit later this year.

The medical dosimetry program

gained provisional accreditation by

the Joint Review Committee on

Education in Radiologic Technology

(JRCERT). Dr. Eduardo Roa led this

effort. We intend to build upon this

success and make the accreditation

final early next year by addressing

the JRCERT recommendations. Our

dosimetry student, Alfredo Banda,

successfully completed the program

and returned to his former

institution, Torrance Memorial

Hospital.

William (Bill) Braggins, a senior

dosimetrist for over a decade,

decided to start enjoying a well-

earned retirement in April. We

welcomed Maxim (Max) Baldytchev

as a locum dosimetrist for the

summer months and Robert

Levesque who filled the Department

manager position.

In the era of digital imaging, no one

seems to remember film. However,

on August 21st everyone appeared to

have re-embraced this obsolete

technology. I saw some of us

scrambling to obtain a few pieces,

cut them to size and stack them for

viewing the partial eclipse. It was

spectacular. It is living proof that the

laws of physics are alive and well and

faithfully obeyed throughout the

universe; whether we are examining

the depths of the nucleus, the human

body, the solar system or the far

reaches of the universe. I admit my

bias. I am not the only one who holds

this opinion. Shakespeare said it best

over four centuries ago in Macbeth

II:iii:55, “We delight in physics”.

I hope all of you and your loved ones

have had a good summer. We look

forward to welcoming all of you to

the Alumni reception that is being

organized by Dr. Randy Wei, a former

resident, who is now practicing at

Long Beach Memorial Medical

Center. It is being held in San Diego

on Saturday September 23rd, 2017

the evening prior to the start of the

ASTRO meeting. I am sure Randy has

e-mailed the details to all of you. He

is a great organizer and will put on a

most enjoyable gathering.

Until then, all the best to all of you

and your respective families.
