Abstract As the representative targeted anticancer drug for colon cancer patients, cetuximab is the EGFR targeted therapeutic antibody and used for treatment of KRAS wild type cancers. Even some patient with KRAS wt gene did not respond cetuximab. However, there is no treatment available for cetuximab-resistant patient group, which is almost 50% of KRAS WT gene holders. Recently, our team identified cetuximab primary resistant related proteins named as mtRTK (mutant receptor tyrosine kinase) by array analysis based cetuximab responder or non-responder colon cancer patient tissues. We investigated mtRTK’s oncogenic potential as a novel anti-cancer target. A large proportion of colon cancer patients (36.2% Caucasian, 56.9% Korean) expressed the mtRTK was identified, using the sequencing analysis of patient samples. Based on these results, our efforts have led to the discovery of WM-S1, mtRTK inhibitor, which is the first mtRTK inhibitor in clinical development. The potent enzyme inhibitor showed a high anticancer activity confirmed in Patient-Derived Cells (PDC) and Patient-Derived Xenograft (PDX) animal models expressing the mutation. In preclinical studies demonstrate that WM-S1 is well tolerated in rats and dogs. Furthermore, WM-S1 has potent anticancer activities for various solid tumor (NSCLC, cholangiocarcinoma, etc.) including activated mtKRAS colon cancer expressing the mtRTK. Currently we are investigating WM-S1 in a phase 1a trial in AUS, which is the first mtRTK inhibitor in clinical development. Meanwhile, the mtRTK inhibitor WM-S1 drives antitumor immunity (with anti-PD-L1) in NSCLC. Combinational approaches with immunotherapy showed that synergistic effect of WM-S1 and anti-PD1 monoclonal antibody, suppressing tumor growth by 75% in anti-PD1 resistance NSCLC-derived humanized mouse model. A phase 1b trial is expected to develop WM-S1 through not only indication expansion but also combination therapy with immuno-checkpoint inhibitors in the USA, AUS and KOR from Q2 2022. In conclusion, mtRTK is a potential oncogenic driver mutation in various solid tumor. A first-in-class anticancer agent WM-S1 targeting mtRTK can be promising therapeutic agents for cetuximab-resistant colon cancer patients regardless of KRAS mutation status and other cancers.

History of Goryeo Dynasty is one of the official histories of Korea and included Goryeo Dynasty’s politic, economy, social culture and biography of public figures which is most important fundamental source for our current studying the ancient history of that time. Therefore, many research studies has been made on the History of Goryeo Dynasty in perspective of manuscript study, literature study and culture study in apart from of history, at present in Korea. This source is written right after establishment of Joseon Dynasty as chronicle of the Goryeo Dynasty’s late period, whereas Korean scholars cannot eject view that political justification view point reflected on establishment of Joseon Dynasty. However, the Goryeo Dynasty’s all time king’s Joseon wangjo sillok (실록. 實錄Veritable Records of the Joseon Dynasty) was used as the main source of creating the History of Goryeo Dynasty and the people present at that time such as “Comprehensive records arranged by year (편년통록. 編年通錄)” by Kim Kwan-ui (김관의. 金寬毅), “Comprehensive records of Gangmo (편년강목. 編年綱目)” by Min Ji (민지. 閔漬), “Records of reflection from Mirror (금경록. 金鏡錄)” by Yi Saek (이색. 李穡)and Yi Yinbok (이인복. 李仁復), “Sikmok pyeonsurok (식목편수록. 拭目編修錄)” and “Prescribed Ritual Text of the Past and Present (고금상정례. 古今詳定禮)” by Choe Yun-ui(최윤의. 崔允儀), “Ikjae-nango(익재난고. 益齋亂藁)” and “Scribbles of Old Man Oak (역옹패설. 櫟翁稗說)” by Yi Jehyeon (이제현. 李齊賢), and “Jugwanyukik (주관육익. 周官六翼)” by Kim, Goo-Yong(김구용. 金九容) are used as reference. Thus, researchers conclude that it describe assure true history of that period and one can say it elevate the value of the source.

Abstract Purpose: Triple-negative breast cancer (TNBC) still relies on non-selective cytotoxic anticancer agents due to the absence of established molecular targets for the phenotype. The heat shock protein 90 (HSP90) is a promising therapeutic target because it affects the overall progression of cancer, including cell proliferation, angiogenesis and metastasis. A variety of N-terminal HSP90 inhibitors have been tried several times in clinical trials, but none have been approved for clinical use to date due to issues including heat shock response (HSR) induction, undesirable effects, and clinical toxicity. In this study, we sought to investigate whether a novel C-terminal HSP90 inhibitor SL-145 could resolve metastasis in TNBC through inhibition of cancer stem-like properties. Experimental Design: The effects of SL-145 on TNBC cell lines in vitro were evaluated in terms of cell proliferation, apoptosis, caspase-3 activity, breast cancer stem cell (BCSC)-like properties and heat shock response. An orthotopic allograft model with 4T1 mammospheres was used to examine the effect of SL-145 on tumor growth and metastasis in vivo. Results: SL-145 induces apoptosis without triggering the HSR and simultaneously inhibits several oncogenic signaling pathways including AKT, MEK/ERK and JAK2/STAT3. SL-145 effectively targets BCSC-like properties with significant reductions in CD44, CD49f and ALDH1 expression as well as impairment of mammosphere-forming ability. To confirm the physiological relevance of our in vitro observations, we investigated the effects of SL-145 on tumor growth, angiogenesis and metastasis in mammosphere-derived allograft tumors with self-renewal capacity. SL-145 administration reduced tumor burden and angiogenesis, which were enriched in BCSCs, and it resulted in significant reductions in lung and liver metastases. In addition, no toxic effects of inhibitors on markers of liver or renal function were observed. Conclusion: Our findings suggest that SL-145 may represent an effective therapeutic approach for targeting cancer stem cells and simultaneous inhibition of the HSP90 client oncoprotein to treat TNBC with a heterogeneous and aggressive nature.

Abstract Background: Previous study have indicated an association of microbial dysbiosis with stages of colorectal cancer (CRC). Meanwhile, higher microbial stochasticity has been introduced as the Anna Karenina principle (AKP) effect, which originates from the opening line of Leo Tolstoy and is translated in the microbiome as “all healthy microbiomes are similar; each dysbiotic microbiome is dysbiotic in its own way”. Here, we aim to elucidate the effect of modifiable factors on microbiome stochasticity related to dysbiosis in CRC. Methods: Fecal samples from 331 CRC patients, were collected prior to their surgery at Seoul National University Hospital. Bacteria that were enriched in early- and late-stage CRC groups were identified by linear discrimination analysis effect size (LEfSE) method, which was then used to calculate microbial dysbiosis index (MDI). The association of dietary choices with microbiome variability was addressed using the LEfSE analysis. The difference of intra-sample similarity index among lifestyle factors and metabolic diseases was tested to examine the AKP effect. A tree-based analysis of food choices was constructed. We then applied Procrustes framework to analyze the shape of dietary diversity and microbiome. Results: The LEfSE identified Leuconostoc, Oxalobacter, Acidaminococcus, and Methanobrevibacter were enriched in early-stage CRC, whereas Bacteroides, Fusobacterium, Lachnoanaerobaculum, Clostridium, and Granulicatella were enriched in late-stage CRC patients. The MDI derived from these bacteria had 64.2% predictive ability for CRC stages, with sensitivity and specificity of 61% and 69%, respectively. The AKP effect was found for history of smoking, alcohol consumption, and diabetes, whereas obesity and hypertension showed anti-AKP effect. For dietary choices, the hierarchical tree of foods and nutrients did not shape the microbial between-sample diversity. Additionally, high MDI was related with a high intake of pizza/hamburger, poultry, and light-vegetable combination. Conclusion: Our study contributed to current evidence of the microbiome structure and dysbiosis at different stages of CRC. Furthermore, history of smoking, alcohol consumption, and diabetes showed AKP effect in CRC patients. Non-significant association between dietary choices and microbiome diversity supported a small variation of microbiome profiles explained by dietary intake at the population level.

Abstract A patient-derived organoid (PDO) is an in vitro three-dimensional model which shows similar features in phenotypic and genetic aspects with primary tissue from patients. PDOs are useful for preclinical studies including drug sensitivity tests of tumors from individual patients as well as development of novel targeted agents. Collectively, PDOs are recently introduced as an emerging platform for personalized medicine. We obtained a total of 100 surgical specimens from 100 patients with breast cancer at the Yonsei Cancer Center, Severance Hospital, Seoul, Korea. One of the tissue specimens was acquired from a breast cancer patient-derived xenograft model. We dissociated the tissues and isolated breast cancer primary tumor cells from the samples, and then the cells were cultured in basement membrane-like matrix in 3D manner with growth medium with supplements. We defined successful establishment of PDOs as continuous growth after 3 passaging. Among all 100 cases, 32 cases failed to culture or passage, however, 41 cases were successfully cultured over 3 passages. In addition, the remaining 27 cases are still in progress of establishment. Success rate of PDO was 68% (68/100). Subtypes of primary tumors of the PDO were 33.8% (23/68) of luminal A, 26.5% (18/68) of luminal B, 26.5% (18/68) of triple-negative, 5.9% (4/68) of triple-positive and 7.4% (5/68) of HER2-enriched. Success rates of each subtype were 69.7% (23/33) of luminal A, 72.0% (18/25) of luminal B, 66.7% (18/27) of triple-negative, 66.7% (4/6) of triple-positive and 55.6% (5/9) of HER2-enriched. Pathologic evaluation using immunohistochemistry revealed that PDOs showed similar morphologic and immunohistochemical features with primary tumors. The selective sensitivity of PARP inhibitor, olaparib, was confirmed in PDOs harboring mutant BRCA1/2 compared with BRCA1/2 wild-type PDOs. Overall, PDOs can be used as a real-time platform for drug sensitivity and screening analyses, and a robust tool for preclinical studies in breast cancer.

Abstract Triple-negative breast cancer (TNBC) harbors a higher cancer stem cell (CSC)-like population and exhibits a more aggressive metastatic phenotype. Due to the limitations of currently available targeted therapies, there remains a significant unmet need for the development of new targeted therapies for TNBC. Molecular chaperone heat shock protein 90 (HSP90) is attracting attention as an ideal therapeutic target due to it regulates essential biological functions such as cell proliferation, angiogenesis and metastasis. Although N-terminal HSP90 inhibitors have had little clinical success to date, C-terminal HSP90 inhibitors have received relatively little attention. We sought to investigate the effects of a new rationally designed NCT-547 on apoptosis, breast cancer stem cell (BCSC)-like properties, migration ability and heat shock response (HSR) in vitro and tumor growth and metastasis in CSC-enriched allograft model in vivo. NCT-547 inhibits TNBC cell proliferation by simultaneously inactivating several survival factors including AKT, MEK, and STAT3. In addition, NCT-547 effectively targets BCSC-like properties with impairment of ALDH1 activity, CD44+/CD24- phenotype, and 3D mammosphere-forming ability. The expression of HSF-1 target genes such as Hsp90, Hsp70, Hsp27, Hsp40 and Hsp65 is highly overexpressed in TNBC patients. The mRNA abundances of target genes were significantly decreased after NCT-547 challenge. NCT-547 effectively targets both the proliferating TNBC tumor cells and CSCs, markedly reducing tumor growth, coinciding with decreased Ki-67 proliferation index and enhanced apoptosis. Anti-tumor effect of NCT-457 was independent of heat shock response as evidenced by significant downregulation of HSF1 phosphorylation and expression of downstream targets HSPs members. It is noteworthy that NCT-547 did not affect markers of hepatic and renal acute toxicity and was not cytotoxic in non-malignant cells. NCT-547 may therefore have potential to address current limitations in the treatment of TNBC.

Abstract Background: Clinical diabetic traits have been reported to be associated with increased colorectal cancer risk (CRC) in observational studies. Using the Mendelian randomization (MR) analysis method, we examined the causal association between glycemic traits, such as fasting glucose (FG), fasting insulin (FI), and glycosylated hemoglobin A1c (HbA1c), and survival in a cohort of CRC patients. Methods: We conducted a two-sample MR analysis among a cohort of patients with locally advanced CRC at Seoul National University Hospital. Single-nucleotide polymorphisms robustly associated (P<5 × 10−8) with the three glycemic traits were obtained from the Meta-Analyses of Glucose and Insulin-related traits Consortium, Asian Genetic Epidemiology Network, and Korea Biobank Array. Three-year and five-year overall survival (OS) and progression-free survival (PFS) were used as outcomes. Survival analysis was conducted using subgroup analysis by cancer stage and subsite in a multivariate Cox proportional hazards model adjusted for age and sex to examine whether glycemic traits affected survival. Results: A total of 509 patients were included in our final analysis. MR analysis showed that HbA1c levels were associated with poor three-year OS (β=4.20, P=0.02). Sensitivity analyses did not show evidence of any violations of the MR assumptions. In the cancer subgroup analysis of the Cox proportional hazards model, pooled hazard ratios for FG were significantly associated with poor three-year OS and PFS regardless of cancer stage. FI was not significantly associated with any three-year survival endpoints. Among stage III patients, three glycemic traits were significantly associated with both five-year OS and PFS. Location-specific subgroup analysis showed a significant association between three glycemic traits and five-year PFS in patients with left-sided colon cancer. FG was associated with poor three-year survival for colon cancer but not rectal cancer. Conclusions: Our results suggest that FG and HbA1c could be used to predict prognosis in CRC patients. Lifestyle and/or pharmacological interventions targeting glycemic traits could help improve survival for CRC patients.

Abstract Background. Sentinel lymph node biopsy (SLNB) is currently the standard axillary staging procedure for clinically node-negative breast cancer. According to the ACOSOG Z0011 trial, axillary lymph node dissection (ALND) is now often omitted for clinically node-negative cT1-2 breast cancer patients undergoing breast-conserving surgery even if 1 or 2 metastatic lymph nodes (LN) are identified. It was shown that radiotherapy contributes to regional control of the axilla non-inferior to ALND even in the presence of metastatic LNs. Furthermore, LN metastasis has a limited role in planning adjuvant systemic therapy for hormone receptor-negative breast cancers, and also for hormone receptor-positive, HER2-negative breast cancer with increased use of genomic assays. SLNB is not without complications and omitting axillary staging operation could improve quality of life. Trial Design. In this multicenter, phase III randomized controlled trial including 9 study sites in South Korea, we plan to 1:1 randomize 1734 patients to either omit SLNB (Arm 1) or receive SLNB (Arm 2). Additional ALND can be performed according to the discretion of the surgeon according to the SLNB results. All patients must receive whole-breast irradiation ± tumor bed boost. The recommended upper margin of the radiation field is within 2cm of the humeral head. ClinicalTrials.gov identifier: NCT04303715. Eligibility. Inclusion criteria: women ≥19 years; cT1-2N0M0 unilateral invasive breast carcinoma; all molecular subtypes; clinically and radiologically tumor size ≤ 5cm; clinically- and ultrasonogram-negative axillary lymph nodes, or no tumor on core needle biopsy or fine needle aspiration cytology in case of suspicious lymph nodes; candidate for breast-conserving surgery with no restriction to radiotherapy and adequate systemic therapy. Exclusion criteria: history of any malignancy within 5 years (exception: thyroid cancer and well-treated skin cancer except melanoma); bilateral breast cancer; neoadjuvant chemotherapy; candidate for total mastectomy; male breast cancer. Specific Aims. Primary objective is to test the hypothesis that omitting SLNB for breast cancer is non-inferior to axillary staging operation in terms of 5-year disease-free survival. Secondary objectives are to compare overall survival, distant metastasis-free survival, locoregional recurrence, quality of life assessment, and DFS and axillary recurrence according to molecular subtypes. Statistical Methods. With an expected 5-year DFS of 86% for Arm 2, Arm 1(SLNB omission) will be assessed with a non-inferiority limit of 5% and hazard ratio of 1.4, power 80%, and significance level of 5%, where 224 events are required. The calculated sample size is 780 per study arm, resulting in a total of 1,734 patients assuming a 10% drop-out rate. Present Accrual and Target Accrual. The first patient was randomized on September 15, 2020. As of July 9, 2021, 480 patients have been randomized. Target accrual of 1734 patients is expected to be complete by April 2023, with the primary endpoint analysis expected in 2028.
