GC Genome enables the prognosis prediction and targeted treatment in breast cancer patients

GC Genome Corporation, a leading genomic diagnostics company, announced the publication of a new study in Journal of the National Cancer Institute (JNCI), shedding light on the remarkable potential of utilizing circulating tumor DNA (ctDNA) copy number aberration (CNA) for prognosis prediction and molecular profiling in cancer patients in collaboration with the team of Dr. Joohyuk Sohn, MD, professor at Severance Hospital.

''We can gain vital insights into patient prognosis and make informed decisions regarding the most effective treatment strategies through ctDNA CNA analysis for breast cancer patients, ultimately improving patients' outcomes," said Dr. Chang-Seok Ki, MD, CEO at GC Genome.

The study includes Low-pass whole-genome sequencing (LP-WGS)-based ctDNA data from 207 metastatic breast cancer (MBC) patients to investigate the prognostic value of ctDNA CNA burden, which was subsequently validated in 465 stage II-III triple-negative breast cancer (TNBC) patients who received neoadjuvant chemotherapy in phase III trial (NCT02441933).

High baseline ctDNA CNA burden was correlated with poor overall survival (OS) and progression-free survival (PFS) of MBC patients and poor disease-free survival was also observed independently of pathologic complete response (pCR), thereby emphasizing the robust prognostic significance of ctDNA CNA burden. PFS and OS are critical indicators of therapeutic efficacy in cancer patients.

''These results will indeed set a solid foundation in paving the way for the integrating of ctDNA CNA analysis into routine clinical practice, offering personalized and targeted treatment options,'' said Dr. Eun-Hae Cho, MD, Chief Technical Officer at GC Genome. "Our dedication to further research aims to ensure that our technology can make valuable contributions to more individuals who are battling against cancer over the world.''

GC Genome’s New Study Reveals Link Between Gut Microbiome and High Blood Pressure

- A large Korean population study provides scientific evidence that altering the gut microbiome composition through dietary habit change can help prevent and manage the hypertension

GC Genome Corporation, a leading genomic diagnostics company, announced the publication of a study in Frontiers in Microbiomes. This study demonstrates the association between gut microbiome and Hypertension, underscoring the importance of the gut microbiome in relation to hypertension in collaboration with the research team at Kangbuk Samsung Hospital. It suggests that modifying dietary habits to alter enterotypes could serve as effective practical approach for managing and preventing hypertension. These findings carry potential implications for individuals seeking to improve their cardiovascular health.

"Hypertension is a complex condition influenced by both genetic and environmental factors. And recent studies suggest that gut bacteria play a role in regulating blood pressure," said Ju Sun Song, MD, Senior director of the research institute at GC Genome. "This research provides the scientific evidence in the large Korean population for the first time that modifying dietary habits, such as consuming fruits, vegetables, and following a traditional Korean diet, can aid in the prevention and management of hypertension."

Hypertension, commonly known as high blood pressure, is a global health concern affecting an estimated 1.13 billion individuals worldwide, as reported by the World Health Organization (WHO). It increases the risk of cardiovascular diseases, including heart disease and stroke, and poses a tremendous public health burden. South Korea, in particular, has witnessed a high prevalence of hypertension due to an aging population and the adoption of a westernized lifestyle. The number of hypertension patients surpassed 12 million in 2018 and continues to rise steadily.

In this study, researchers recruited over 600 Korean patients who underwent medical checkups, and their gut microbiomes were analyzed using Next-Generation Sequencing (NGS) technology. The team compared four enterotypes based on dietary habits: Prevotella, Bacteroides1, Bacteroides2, and Ruminococcaceae. The results indicated that the Bacteroides2 enterotype, characterized by high animal fat consumption and low microbial diversity, strongest associated with hypertension. Conversely, the Ruminococcaceae-dominant enterotype, linked to a higher intake of vegetables and fruits, displayed the lowest association with hypertension. Notably, these findings align with the recommendations in the 2017 hypertension clinical guidelines, which suggest increasing the consumption of vegetables, fresh fruits, fish, nuts, and unsaturated fatty acids while reducing the intake of red meat.

In addition, it was also confirmed that hypertension occurring in the Bacteroides 2 enterotype had a significantly lower ratio of Faecalibacterium rather than other enterotypes. Faecalibacterium ferments dietary fiber that has reached the large intestine without being digested or absorbed, thereby producing short chain fatty acids (SCFAs) having anti-inflammatory effects and is promising beneficial bacterium that is in the spotlight as a next-generation probiotics. Therefore, the study also emphasizes the importance of considering enterotypes in clinical studies exploring hypertension interventions, such as short-chain fatty acids (SCFAs) or Faecalibacterium. Further investigation is needed to fully understand the interaction of gut microbiome with the food we eat and our health.

GC Genome-KAIST team Announces Publication of a Groundbreaking AI-Based Liquid Biopsy Technology for Multi-Cancer Early Detection and Localization in Nature Communications

GC Genome-KAIST team Announces Publication of a Groundbreaking AI-Based Liquid Biopsy Technology for Multi-Cancer Early Detection and Localization in Nature Communications

GC Genome Corporation, a leading genomic diagnostics company, today announced the publication of a new study in Nature Communications, showcasing the company's novel AI-based liquid biopsy technology. The study highlights the unprecedented accuracy of the technology for cancer early detection and tissue-of-origin localization utilizing advanced AI algorithms to analyze mutation density and patterns of cell-free DNA (cfDNA) and epigenomes in collaboration with the Korea Advanced Institute of Science and Technology (KAIST).

Noninvasive screening by cfDNA holds great promise for multi-cancer early detection. The cancer early detection of various types is an important part of cancer treatment since cancer has a better prognosis and survival rate when diagnosed and treated earlier[1].[2]. However, de novo detection of cancer, especially at early stages, remains challenging and the solution for this urgent need is being actively pursued by using cfDNA-based noninvasive cancer screening for Multi-Cancer Early Detection (MCED) and localization of cancer[3]. 

"Since cancer screening technologies are limited or premature, diagnostic tests are usually performed after symptoms arise, and early intervention opportunities are often missed, leaving few treatment options," said Dr. Jung Kyoon Choi, Department of Bio and Brain Engineering, KAIST. "We hope that our methods leveraging large-scale tumor genomes and epigenomes as reference data lay the groundwork for accurate cfDNA-based cancer diagnosis at early stages."

The Nature Communication study includes a total of 2,543 cancer patient samples and 1,241 normal control samples and describes an ensemble algorithm that incorporates genomic and epigenomic profiles of tumor tissues into a deep learning model. This model analyzes mutation distribution and chromatin organization in reference tumor tissues and uses them as model features to detect the existence of cancer and determine the type of cancer in cfDNA samples. 

The technology has demonstrated promising results in detecting multiple types of cancer at an early stage. The technology has shown exceptional sensitivity, achieving a 91.1% performance rate based on a 95% specificity and a high level of accuracy, with an 81.7% success rate in predicting both the presence and type of cancer. 

"These results suggest that the GC Genome AI-based cancer early detection technology could help reduce cancer deaths by offering a convenient, high-performing test to people," said Dr. Eun-Hae Cho, MD, Chief Technical Officer at GC Genome. "We will continue our research to improve accuracy and sensitivity and look forward to making our technology accessible to all cancer patients worldwide."

GC Genome Announces Publication Demonstrating Feasibility of Liquid Biopsy Technology to Predict Radiation Therapy Response in Solid Tumors

GC Genome Corporation, a leading genomic diagnostics company, announced the publication of a new study in Radiation Oncology Journal, which demonstrates the feasibility of cell-free DNA(cfDNA) monitoring to predict treatment response and detect minimal residual disease after radiation therapy(RT) in solid tumor patients using I-score, a tool for calculating genomic instabilities developed by GC Genome. The research was in collaboration with the Samsung Medical Center, Sungkyunkwan University School of Medicine. This study adds to the previous studies of prognostic effects of the I-score in various solid tumors, including hepatocellular carcinoma, esophageal cancer, and pancreatic adenocarcinoma1.2.3.

The study analyzed 23 plasma samples from cancer patients across a range of lung, esophageal, and head and neck cancer, and plasma samples from 358 healthy people were used as negative controls. Test performance was evaluated at serial cfDNA monitoring points: before RT, 1 week after RT, and 1 month after completion of RT using I-score, which represents chromosomal alterations across the genome(CIN) of cfDNA from Low-coverage whole genome sequencing(LC-WGS) data.

The result showed that pretreatment I-scores tended to be higher in larger tumors, and there was a significant positive correlation between the gross tumor volume and the baseline I-score. Another interesting finding is that minimal residual disease following RT was detected earlier by cfDNA than by imaging studies. And the serial monitoring of the I-score in the post-treatment 4 months case demonstrated that the change in I-score was observed before the progression of the disease was detectable through imaging studies. 

"The findings of this study may have significant implications for the field of oncology, particularly for patients with lung, esophageal, and head and neck cancer," said Dr. Chang-Seok Ki, MD, CEO at GC Genome. "Further additional studies are ongoing to optimize the measurement and analysis of I-scores to predict radiation response accurately. The potential of cfDNA I-score as a monitoring tool in cancer treatment deserves continued investigation and attention."
