Treatment Philosophy
I chose to stay at Fox Chase as an attending physician for the love of the institutional environment and the great patients I am so privileged to treat. I love my work for the great team spirit cultivated among my colleagues, physicians and nurses. I am extremely grateful to the fact that patients are at the center of everybody’s attention. It is easy for me to do my job in such an atmosphere of concern and indefatigable compassion.
Fox Chase also offers me an opportunity to work both in the clinic and in the lab, where I am studying cancer biology with the goal to design better treatment options for the patients. In my field of gastrointestinal malignancies, I am convinced that the treatment choices for each individual cancer patient will soon be defined by the molecular makeup of their cancer cells. This knowledge can help us match the treatment strategies with the biology of individual patient’s tumors. I am interested to translate the knowledge about cancer available in the lab to the clinic by conducting hypothesis-driven clinical trials.
I am deeply convinced that the best way to help our patients is to push the boundaries by doing clinical and basic research.

Patient Stories
Barry Dixon
Neuroendocrine Tumors
Barry Dixon
Neuroendocrine Tumors
In September 2009, Barry Dixon was living and working in South Carolina with his fiancé and their son, Robert Phillip. As a maintenance technician for an apartment management firm, Barry performed a lot of physical labor. One day, while helping his cousin move, Barry thought he pulled something in his abdominal area. It caused more pain than he was used to. He went to the doctor on a Friday, who ordered further testing for the following Monday.

Research Interests
Cancer Metabolism and signaling
- The central role for sterol metabolism in regulation of cell growth and signaling
- Pancreatic cancer biology and "smart drugs" for treatment of pancreatic cancer
- Translating therapeutic concepts to the clinic using the platform of patient-derived avatar models and genetically engineered pancreatic cancer models
Lab Overview
My lab opened in 2009 endowed with the challenge to define the critical regulators of tumor cell response to drugs targeting EGFR (Astsaturov, Science Signaling, 2010). From this initial task which ultimately led to 2 clinical trials in patients with head and neck and lung cancers, 3 NIH grants and 6 papers, we define a previously overlooked step of C4-demethylation in the enzymatic cascade of cholesterol biosynthesis. Inactivation of SC4MOL or NSDHL involved in the oxidative demethylation at C4 leads to dramatic alteration in the vesicular trafficking of the endocytosed EGFR and sensitizes cancer cells to EGFR inhibitors (Sukhanova, Cancer Discovery, 2013).
Following this initial lead, Linara Gabitova took on the challenge to pinpoint the mechanism executing such a dramatic effect of accumulating C4-methylated sterols. She found that LXR alpha was the critical effector triggered by these sterol species, so that activation of LXR can be used to deregulate cholesterol turnover in cancer synergistically with EGFR antagonists in in the KRAS-driven tumors (Cell Reports, 2015).
Our current interests are focused on pancreatic cancer where KRAS is the causative oncogenic mutation. We are looking for metabolic vulnerabilities in the cholesterol pathway as well as developing innovative drug delivery tools to improve lives of the patient with this devastating and thus far recalcitrant cancer.
