Curated and Standardized Research Datasets

ICBI faculty conduct research using public and proprietary datasets to advance Precision Medicine. They are involved in developing and applying Bioinformatics and Medical informatics methods to derive actionable knowledge from genomics, electronic health records, registries, patient-reported, public health and other datasets. 

Below is a list of specialized datasets that were co-developed by ICBI investigators and collaborators. These datasets are currently managed by ICBI and available to GUMC investigators for research use. Please contact the ICBI investigators listed under each dataset to initiate a collaboration.

1. REMBRANDT (REpository for Molecular BRAin Neoplasia DaTa) Dataset 

ICBI Investigators – Yuriy Gusev, Krithika Bhuvaneshwar, Camelia Bencheqroun, Subha Madhavan

Description: The REMBRANDT dataset was originally created at the National Cancer Institute and funded by Glioma Molecular Diagnostic Initiative. The data was collected from 2004-2006. In 2015, the NCI transferred this dataset to Georgetown, and it is now physically located on the Georgetown Database of Cancer (G-DOC), a cancer data integration and sharing platform for hosting alongside other cancer studies. REMBRANDT includes genomic data from 261 samples of glioblastoma, 170 of astrocytoma, 86 tissues of oligodendroglioma, and a number that are mixed or of an unknown subclass. Outcomes data include more than 13,000 data points.

The dataset is accessible for conducting clinical translational research using the open access Georgetown Database of Cancer (G-DOC) platform. In addition, the raw and processed genomics and transcriptomics data have also been made available via the public NCBI GEO repository as a super series GSE108476 . Such combined datasets would provide researchers with a unique opportunity to conduct integrative analysis of gene expression and copy number changes in patients alongside clinical outcomes (overall survival) using this large brain cancer study

2. Georgetown Pediatric Cancer Outcomes Database

ICBI Investigators: Shruti Rao, Subha Madhavan

Collaborators: Aziza Shad, Kenneth Tercyak

Description: The Georgetown Pediatric Cancer Outcomes Database was co-developed by investigators at the Georgetown University Medical Center (GUMC) Lombardi Comprehensive Cancer Center (LCCC), the Pediatric Hematology Oncology and Bone Marrow Transplantation Program and ICBI. The 620 pediatric cancer patients (as of May 2015) in this database were diagnosed with various cancers at Lombardi Cancer Center’s Pediatric Oncology Program and were enrolled or treated as per Children’s Oncology Group (COG) protocols between 1990 and 2014. GUMC’s EMR systems – ARIA, AMALGA along with the paper charts were curated to obtain complete clinical information for these patients. Several retrospective research projects have been conducted on this pediatric cancer outcomes database such as – evaluation of secondary cancers in this patient cohort after therapy; assessment of risk factors associated with childhood cancer therapy and extracting predictor variables for late effects of childhood cancer treatments from clinical notes.

3. Georgetown Immuno Oncology Registry

ICBI Investigators: Anas Belouali, Subha Madhavan

Collaborators: Neil Shah, Michael Atkins

Description: Our multidisciplinary team of clinicians and informaticians built a centralized research data warehouse for ImmunoOncology that is enabling novel hypothesis generation and retrospective outcomes research at the 10 DC-Baltimore based MedStar Health network hospitals. Data sources include hospital medical records, Labs, pathology, radiology, and Cancer Registry data. Data was extracted from different hospital systems and integrated into REDCap to allow clinicians to capture additional data from patient charts. Our integrative approach helps assess outcomes in patients with different comorbidities across all hospitals, effects of treatment with steroids on immune toxicities and their outcomes, use of various drugs before and during ImmunoOncology treatment and their impact on outcomes and toxicities. Toxicities and adverse events data in EHRs is not comprehensive. Hence, in addition to data extracted using ICD codes from structured fields/tables, we are using our in house developed NLP methodologies to automatically identify toxicities in patient charts. The Immuno Oncology registry has 758 patients as of Jan 2020.

4. CARIS Molecular Diagnostic Dataset

ICBI Investigators: Kanchi Krishnamurthy

Collaborators: John Marshall

Description: Molecular profiling of any patient’s tumor identifies their disease biomarker pattern that then allows that patient’s medical team to select personalized treatment options that they may not have previously considered. ICBI investigators collaborated with the Ruesch center on a project that involves the molecular profiling of cancer patients seen at Georgetown. We obtained and analyzed test results of around 3900 patients (as of Jul 2019) from Caris Molecular Intelligence™ service with the ultimate goal of better informing treatment decisions. We are currently pursuing several projects centered around these datasets, including correlating survival with choice of standard vs personalized treatment, correlation of mutational burden and microsatellite instability in colorectal cancer, development of open-source visualization and analysis tools for molecular profiling, and comprehensive comparisons with public resources such as TCGA and AACR Genie.

5. Stage II Colorectal Cancer – Multi-omics Molecular Profiling Dataset 

ICBI Investigators: Yuiry Gusev, Krithika Bhuvaneshwar
Collaborators: Lou Weiner

Description: Colorectal cancer (CRC) patient biospecimens with extensive clinical and follow-up data were selected from the Indivumed GmbH biobank for 40 patients (20 relapse and 20 no-relapse). The patients consisted of 12 with late stage I, and 28 with stage II. Four patients (out of 12) with late stage I had experienced relapse (~33%), and it is important to note that 12 patients (out of 28) with stage II were relapse-free (~43%). Therefore, the relapse-free group of samples, and the group with relapse are both represented by a mixture of late stage I and stage II patients. Only nine stage II patients (out of 28) had rectal cancer; of these 6 had relapsed within 5 years. Of more than 180 clinical attributes, 64 were shortlisted based on relevance to clinical outcome and biomarker analysis. The molecular data included gene expression, DNA copy number, microRNA, serum and urine metabolites.

6. ICBI Molecular Simulation Datasets 

ICBI Investigators: Matthew McCoy

Description: Protein structure simulation results generated from the SNP2SIM workflow, and used to develop protein specific models of variant function. Contains metadata on simulation configuration/parameterization, and output from Nanoscale Molecular Dynamics (NAMD) and Autodock Vina. 

Data Formats: NAMD output binaries (MD simulation results) or text files stored in the SNP2SIM defined file structure.

7. OMOP-mapped Cancer Dataset (under-development)

ICBI Investigators: Shuo Wang, Kanchi Krishnamurthy, Adil Alaoui

Description: Our team is developing short and long-term strategies to map oncology-specific electronic health record data (EHR) hosted and managed in ARIA into the Observational Medical Outcomes Partnership common data model (OMOP CDM), which is one of the leading standard data models used in nationwide research and information sharing initiatives. OMOP was developed to be a shared analytics model and it has been adopted by the Observational Health Data Sciences and Informatics (OHDSI) Consortium. Our approach was to transform oncology EHR data and related databases into a common format as well as a common representation (terminologies, vocabularies, coding schemes), and then perform systematic analyses using a library of standard analytic routines that were developed and shared by the community based on the common data format.

8. Curated dataset for CDGnet

ICBI Investigators: Simina Boca

Collaborators: Hector Corrada Bravo
