Association of Genomic Polymorphisms With Cancer Cachexia in Subjects With Pancreatic Adenocarcinoma
Wake Forest University Health Sciences
Summary
A major complication of pancreatic adenocarcinoma (PDAC) is cancer cachexia (CC) which is a complex syndrome characterized by skeletal muscle mass loss (with or without loss of fat mass) and progressive functional impairment not reversible by conventional nutritional support. It is estimated to occur in over 75% of patients with advanced PDAC, the highest incidence of all solid tumors, and contributes significantly to poor outcomes and mortality. Though there is overlap amongst the pathophysiologic studies evaluating CC in murine models of different tumor types, the high prevalence of CC within gastrointestinal (GI) malignancies and specifically PDAC suggest that dedicated studies evaluating polymorphisms in candidate genes specific to PDAC warrant further evaluation. The collection and analysis of specimens under this study will facilitate the identification and characterization of genomic polymorphisms associated with CC in PDAC patients. Subsequently, this data may help contribute towards diagnostic and therapeutic treatments that may improve patient outcomes.
Description
This pilot study consists of a cohort of 100 locally advanced unresectable or metastatic PDAC subjects with a prospective analysis of biomarkers that may be associated with CC, a major negative prognostic factor in outcomes. The study protocol-directed assessments consist of four experimental measures (gene single nucleotide polymorphisms and available clinical information including weights, imaging review of sarcopenia, and select labs) used to determine factors that potentially contribute to CC in subjects with PDAC. Main confounding factors to be evaluated include stage of disease, receipt…
