The goal of this study is to assess a slimy substance that settles/deposits along blood vessel wall. This slimy substance is called plaque. Plaque could be made up of fat, calcium or both. Plaque deposition narrows the vessels. This leads to decreased blood flow to various parts of body. Blood vessels include vessels that supply to heart (coronary), vessels to brain (carotid), vessels to kidneys (renal) and vessels to legs (femoral). Decreased blood flow causes symptoms such as brain stroke, heart attack, leg pain. Similarly individuals at risk of cardiovascular disease can have certain markers elevated in their blood that can be measured by simple blood tests.
High or increased plaque deposition is seen in neck vessels of cancer patients who received radiation to chest or head and neck as part of their cancer treatment. Cancer survivors are at increased risk of plaque development and are therefore called high-risk population. Exercise +/- fat lowering medicine can potentially decrease plaque deposition and statins are one of the several fat lowering medications.

Cardiovascular disease (CVD) and cancer are the leading causes of suffering and death amongst the American population. While an ever-increasing number of cancer survivors have a favorable outcome due to advances in cancer treatment; cancer survivors remain at high risk of developing CVD at an early age. There is scant information available on the pathogenic process that contributes to cardiovascular threat amongst cancer survivors and little is known about the interventions, which may interrupt or decrease the risk of CVD in this population. Importantly, early-subclinical markers may substantially precede clinical markers.
The objective of this project is to accurately determine the constituents and characteristics of atherosclerotic plaques in carotid arteries by magnetic resonance imaging (MRI) techniques in cancer survivors; at different data intervals: before and after administration of treatment (medical and life style modification) and then correlate contrast agent dynamics with serum markers of inflammation and other tests of cardiac or vascular dysfunction, where available.
The proposed study involves 100 asymptomatic patients who received prior chest or head and neck radiation therapy (HNXRT) as part of cancer treatment. MRI data (direct assessment of atherosclerosis) would be correlated with indirect measures of atherosclerosis (blood surrogate markers & metabolomics).
The investigators intend to conduct an initial baseline MRI, blood tests (to correlate with surrogate markers of inflammation) and other tests whenever available of cardiac or vascular dysfunction. This cohort will be followed up with medication and/or life style modification regimen for a period of initially18 months and subsequently at 36 months. A repeat of all baseline studies (MRI and blood tests) would be performed as part of the 18 and 36-month follow-up. The plaque characteristics found at MRI will be correlated with results of blood tests (baseline, 18 and 36 months) and changes in one or both will be the expected end point of the study.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||9 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||The protocol originally specified randomizing participants to a study arm, but the protocol was amended to clarify that a participant's cardiologist could change the treatment regimens that participants were assigned to so that no participant was restricted from statin therapy.|

Active Comparator: Lifestyle modification
Lifestyle modification is tailored to each participant and includes a recommended exercise regimen, a healthy diet and decreasing alcohol intake.
Behavioral: Lifestyle modification
Lifestyle modification includes a recommended exercise regimen, a healthy diet and decreasing alcohol intake for 3 years.
Experimental: Statin therapy
Participants will receive statin medication along with instruction about regular exercise.
Drug: Statin therapy
Statin therapy includes rosuvastatin 20 mg administered orally, once a day, for the duration of the trial, which is 3 years. Participants may also receive a different type of statin as prescribed by their cardiologist based on clinical judgement.
Other Name: Crestor
- Plaque Volume of Carotid Arteries [ Time Frame: Baseline, 18 months, 36 months ]Plaque volume of carotid arteries were measured by MRI as a surrogate for progression of cardiovascular disease. Plaque volume varies with observed ranges from other studies ranging from 23.9 to 604.1mm^3. Plaque volume tends to increase with age. Increased plaque volume has an increased risk of vascular events.
