ABSTRACT: The objective of this Study is to collect, process, and transfer biologic samples such as blood and/or tissue biopsies to determine the concordance of detected alterations obtained through liquid biopsy analyses compared to next generation sequencing of time-matched or archival tissue specimens from individuals with advanced solid tumors. Examples of locally advanced and metastatic tumors include stage III and IV cancers (ex. lung, breast, all gastrointestinal malignancies, all gynecologic malignancies, prostate cancer, head and neck tumors, soft tissue cancers, and melanoma). These specimens will be analyzed for diagnostic purposes and research (either by Labcorp/OmniSeq or to a third-party recipient designated by Labcorp/OmniSeq). Labcorp/OmniSeq may transfer the specimens and data to its clients, including commercial, academic or non-profit research institutions; or alternatively, may retain the specimens in its repository for future research use at the sole discretion of Labcorp/OmniSeq and or assignees. Labcorp/OmniSeq will maintain all detailed clinical information including demographic data (de-identified), ethnicity, disease state, stage (radiological, pathological and clinical-whichever is relevant).

Project description:The emergence of omics technologies over the last decade has helped in advancement of research and our understanding of complex diseases like brain cancers. However, barring genomics, no other omics technology has been able to find utility in clinical settings. The recent advancements in mass spectrometry instrumentation have resulted in proteomics technologies becoming more sensitive and reliable. Targeted proteomics, a relatively new branch of mass spectrometry-based proteomics has shown immense potential in addressing the shortcomings of the standard molecular biology-based techniques like Western blotting and Immunohistochemistry. In this study we demonstrate the utility of Multiple reaction monitoring (MRM), a targeted proteomics approach, in quantifying peptides from proteins like Apolipoprotein A1 (APOA1), Apolipoprotein E (APOE), Prostaglandin H2 D-Isomerase (PTGDS), Vitronectin (VTN) and Complement C3 (C3) in cerebrospinal fluid (CSF) collected from Glioma and Meningioma patients. Additionally, we also report transitions for peptides from proteins – Vimentin (VIM), Cystatin-C (CST3) and Clusterin (CLU) in surgically resected Meningioma tissues; Annexin A1 (ANXA1), Superoxide dismutase (SOD2) and VIM in surgically resected Glioma tissues; and Microtubule associated protein-2 (MAP-2), Splicing factor 3B subunit 2 (SF3B2) and VIM in surgically resected Medulloblastoma tissues. To our knowledge this is the first study reporting proteins from three types of brain malignancies and two different bio-specimens. Future studies involving a large cohort of samples aimed at accurately detecting and quantifying peptides of proteins with roles in brain malignancies could potentially result in a panel of proteins showing ability to classify and grade tumors. Successful application of these techniques could ultimately offer alternative strategies with increased accuracy, sensitivity and lower turnaround time thus making them translatable to the clinics.
