研究概览
简要总结
The purpose of this study is to measure certain specific chemicals in your blood, produced by the body in response to a stress, such as having pancreatic cancer. These chemicals are called "cytokines" and the researchers doing this study want to look at the role they may play in developing depression.
详细描述
Pancreatic cancer is the 5th leading cause of cancer mortality in the United States, with a 5 year mortality rate of over 95%. With limited treatments available for cure or prolongation of survival, quality of life issues, such as the optimal treatment and understanding of depression, become an important focus of care in this population. Clinical Depression (Major Depressive Syndrome) occurs in up to 50% of patients with pancreatic cancer, and is significantly more common than in other cancers. Accumulating evidence suggests a potential role for endogenous cytokines, specifically interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in the development of depression in the medically ill, including cancer patients. These same cytokines have been noted to be elevated in pancreas cancer patients. The main goal of this pilot study is to examine the role of specific endogenous cytokines (IL-1, IL-6, TNF-alpha, as well as IL-10, Il-15 and IFN-gamma) in the development of Major Depressive Syndrome (MDS) in patients with pancreatic cancer. To achieve our goal, we will examine the relationships between serum cytokines (IL-1, IL-6, TNF-alpha, as well as IL-10, Il-15 and IFN-gamma) and clinical depression (i.e. MDS) utilizing a cross sectional design in 4 samples of patients: a) Pancreas cancer patients with a DSM-IV diagnosis of MDS (N=25); b) Pancreas cancer patients without a DSM-IV diagnosis of MDS (N=25); c) Healthy Controls with a DSM-IV diagnosis of MDS (N=25); and d) Healthy Controls without a DSM-IV diagnosis of MDS (N=25). Measures will include a structural clinical interview for DSM-IV diagnosis (SCID) of Major Depressive Syndrome, as well as measures of depressive symptom severity, fatigue severity, concentration and attention, and cognitive function. Plasma concentrations of endogenous cytokines ((IL-1, IL-6, TNF-alpha, as well as IL-10, Il-15 and IFN-gamma) will be measured utilizing standard assays. Our specific aims are: 1) To preliminarily examine the relationships between plasma concentrations of endogenous cytokines (IL-1, Il-6, TNF-alpha, as well as IL-10, Il-15 and IFNgamma) and a DSM-IV diagnosis of Major Depressive Syndrome in patients with pancreas cancer and healthy controls; 2) To explore the relationships between plasma concentrations of endogenous cytokines (Il-1, Il-6, TNF-alpha, as well as IL-10, Il-15 and IFN-gamma) and the phenomenology and severity of depressive symptoms, presence and severity of fatigue, and degree of impairment in attention, concentration and cognition, in depressed patients with pancreas cancer and healthy depressed controls. The results of this pilot study will be utilized to seek NIH funding for larger, longitudinal, multi-institutional, studies examining the role of endogenous cytokines in pancreas cancer patients, as well as clinical intervention trials for the treatment of clinical depression in pancreas cancer patients that utilize specific cytokine antagonists as adjuncts to antidepressant drug therapies.

入选标准
- •40 years of age or older at the time of recruitment.
- •Unresectable/inoperable pancreatic adenocarcinoma (stage III or IV), receiving Gemcitabine or Gemcitabine-based combination therapy.
- •If in the "depressed" sample, patients with pancreatic cancer must meet DSM-IV criteria for a major depressive syndrome (based on the SCID) AND have an HDRS score of 18 or greater.
- •If in the "non-depressed" sample, patients with pancreatic cancer must not meet DSM-IV criteria for a major depressive syndrome (based on the SCID) AND must have a HDRS score of 17 or less.
排除标准
- •A. Patient has reported experiencing or medical record indicates a serious medical event (i.e.,medical hospitalization (excluding hospitalization related to cancer diagnosis/treatment),myocardial infarction, stroke) within the year preceding study participation.
- •B. Patient has reported the presence of or medical record indicates:
- •Type 1 Diabetes, unrelated to cancer diagnosis
- •renal failure requiring dialysis
- •inflammatory bowel disease
- •Patient has reported the presence of or medical record indicates an active secondary cancer diagnosis, however patients who have been treated for a past cancer and are 2 years disease free from that cancer can participate.
- •Presence of a medical/surgical condition obtained through self-report associated with elevated cytokine levels, such as:
- •Auto-immune diseases such as SLE, Multiple Sclerosis, Rheumatoid Arthritis, Polymyalgia Rheumatica, Temporal Arteritis, Chronic Fatigue Syndrome, severe allergies
- •Congestive Heart Failure
- •Recent stroke
- •Alzheimer's Disease
- •Active infection;
- •Acute pancreatitis
- •Acute pericarditis
- •Acute hepatitis including Hepatitis C
- •Recent vaccination for viral disease
- •Major surgery within the past 6 weeks
- •Patient Reports Receiving treatment (within two weeks) with:
- •Interleukin
- •Interferon
- •Thalidomide
- •Cox-2 inhibitors
- •Cancer vaccine therapies
- •Self-reported diagnosis with a major psychiatric disorder other than depression (e.g. psychosis secondary to Bipolar Disorder, Schizophrenia, Schizo-affective illness, substance abuse) so severe that, in the opinion of the study staff, would interfere with a patient's ability to give informed consent for research.
- •Cognitive impairment so severe that, in the opinion of the study staff, would interfere with a patient's ability to give informed consent or complete study measures for research.
