12/19/17 - Robin &
Rusthoven report remarkable radiosurgery results
Drs. Tyler Robin, PGY-4 resident in radiation oncology, and Chad Rusthoven, Assistant Professor of Radiation Oncology, have published a paper in the Journal of Thoracic Oncology demonstrating excellent survivorship in patients with four or more brain metastases from EGFR-mutated and ALK-rearranged lung cancer treated with radiosurgery alone. A median survival of 3.0 years (4.2 for ALK, 2.4 for EGFR) from the diagnosis of brain metastases was achieved, and survival was equivalent regardless of number of radiosurgery courses, number of tumors treated in total, or number of tumors treated in a single radiosurgery session.
“It used to be that once lung cancer metastasized to the brain, the prognosis was
poor. Whole brain radiation therapy decreases the risk of death from neurologic causes, but at a steep cost. This study suggests that for lung cancer patients on targeted therapies whose cancer has spread to the brain, the use of radiosurgery makes it rare to die of causes related to brain metastases,” says Tyler Robin, MD, PhD, the paper’s first author. Robin also measured dose to non-target structures such as the hippocampus and demonstrated that radiosurgery yielded substantially lower dose to this and other parts of normal brain than even the most sophisticated techniques of whole brain radiotherapy. Adds senior author Dr. Rusthoven, “The very low dose of radiation to the normal brain observed with radiosurgery compared to whole-brain radiation has the potential to dramatically lower the risk of cognitive side effects.”

He also served as Associate Program Director of the Radiation Oncology residency and Faculty Advisor of the medical student interest group. Outside of work, Dr. Nath enjoys playing soccer and spending time with his two young boys, Jack and Max, and his wife, Dr. Alison Sheridan, who is a radiologist also joining the faculty at the University of Colorado in the Body Radiology section.
4/24/17 - Karam awarded RSNA grant
Dr. Sana Karam and
her lab team have been awarded a grant from the Board of Trustees of the
Radiological Society of North America (RSNA). The project that will be
supported, entitled “
Combined Inhibition of EphB4 and EGFR Signaling
Enhances Radiosensitization in Head and Neck Cancers”, will focus on novel
mechanisms of interaction between radiation and the Eph family of ligands and receptors, an area in which Dr. Karam has become a
leading expert. “I am excited that we will have an opportunity to fill in a few
important gaps in our understanding of the best way to combine radiation and
certain new agents in head and neck cancer,” says Dr. Karam. “We are moving
very close to a point where we will be able to offer this type of combination
to patients in clinical trials, and I think there is reason to expect we can
improve tumor cure rates for certain groups of patients."
4/21/17 - Alexeev wins AAPM Junior Investigator Competition
Dr. Timur Alexeev, a
post-doctoral fellow of the Medical Physics section, has been selected as the
winner of the Junior Investigator Competition of the American Association of
Physicists in Medicine (AAPM) Annual Meeting for his abstract, “Development and
Evaluation of a Two Dimensional Antiscatter Grid for CBCT”. The work was
accomplished under the supervision of Dr. Cem Altunbas, who is principal
investigator of an NIH R21-funded project addressing the challenges of how to
improve cone-beam CT scanning (CBCT), an imaging technique relied upon heavily
for high precision image-guided radiation therapy (IGRT). “Dr. Alexeev’s
work has demonstrated important fundamental principles in this study and
established that our grid technique improves image quality,” notes Dr. Altunbas,
who adds, “and this work lays a foundation for implementing the new techniques
in the clinic in the near future."
2/15/17 - Robin’s Research
Cited in New York Times Article on Disparities
recent publication authored by Dr. Tyler Robin, PGY-3, Department of Radiation
Oncology, has received national attention. The article, “Disparities
in standard of care treatment and associated survival decrement in patients
with locally advanced cervical cancer”, was cited in a New
York Times article addressing disparities in cervical cancer treatment.
Christine Fisher commented, “Dr. Robin's study revealed a very important
and concerning point. Fewer than half of patients with locally advanced cervix
cancer receive appropriate standard therapy for their cancer, which should
include both external beam radiotherapy and brachytherapy. Patients were more
likely to receive substandard therapy if they had lower incomes, only Medicaid
insurance, or treatment outside of a comprehensive cancer center. We hope that
by illuminating the problem we can educate patients and providers outside of
major centers that referral to a comprehensive cancer center like ours is
important if the appropriate expertise and technology for proper treatment is
unavailable locally. Cervix cancer can be challenging to treat but is
potentially curable, and it is important that the oncology community rallies to
the support of the vulnerable populations of patients who need access to
standard care. Our ultimate hope is for elimination of cervical cancer
through vaccination and screening, but, until then, access to best care is
critically important for cervix cancer patients.
of the study included Dr. Arya Amini, PGY-5, Department of Radiation Oncology; Dr.
Tracey Schefter, Department of Radiation Oncology; and Dr. Kian Behbahkt,
Director of Gynecologic Oncology.
