Journal ArticleDOI
Prognostic implications of tumor-infiltrating FoxP3+ regulatory T cells and CD8+ cytotoxic T cells in microsatellite-unstable gastric cancers.
Kyung Ju Kim,Kyu Sang Lee,Hwa Jin Cho,Young Hoon Kim,Han-Kwang Yang,Woo Ho Kim,Gyeong Hoon Kang +6 more
TL;DR: It is demonstrated that higher densities of both intratumoral CD8+ and FoxP3+ TILs are associated with good prognosis, suggesting a synergistic activity of these 2 subsets that can be used as an independent prognostic factor in MSI-high GCs.
Journal ArticleDOI
Epithelial-mesenchymal transition increases during the progression of in situ to invasive basal-like breast cancer
Y.M. Choi,Hee Jin Lee,Min Hye Jang,Jae Moon Gwak,Kyu Sang Lee,Eun-Joo Kim,Hyun Jeong Kim,Hee Eun Lee,So Yeon Park,So Yeon Park +9 more
TL;DR: This study confirmed that EMT is an intrinsic characteristic of basal-like subtype and is associated with CSC phenotype and showed higher expression of EMT markers in invasive carcinomas than in pure DCIS, especially in basal- like subtype, and in the invasive component of basal -like breast cancers, suggesting that E MT may be involved in the progression from in situ to invasive basal-Like breast cancers.
Journal ArticleDOI
Prognostic implication of CD274 (PD-L1) protein expression in tumor-infiltrating immune cells for microsatellite unstable and stable colorectal cancer.
Kyu Sang Lee,Yoonjin Kwak,Soyeon Ahn,Eun Shin,Heung Kwon Oh,Duck Woo Kim,Sung Bum Kang,Gheeyoung Choe,Gheeyoung Choe,Woo Ho Kim,Hye Seung Lee,Hye Seung Lee +11 more
TL;DR: CD274 expression in tumor-infiltrating immune cells was an independent factor for improved prognosis in CRC patients and a deeper understanding of CD274 status may yield improved responses to future CRC immunotherapies.
Journal ArticleDOI
Effect of Platinum-Based Chemotherapy on PD-L1 Expression on Tumor Cells in Non-small Cell Lung Cancer.
Junghoon Shin,Jin Haeng Chung,Se Hyun Kim,Kyu Sang Lee,Koung Jin Suh,Ji Yun Lee,Ji Won Kim,Jeong Ok Lee,Jin Won Kim,Yu Jung Kim,Keun Wook Lee,Jee Hyun Kim,Soo Mee Bang,Jong Seok Lee +13 more
TL;DR: Increase in tumor PD-L1 expression may predict poor clinical outcome after platinum-based NACT, and that pattern was consistent across clinically defined subgroups except for patients with partial response to NACT.
Journal ArticleDOI
c-MYC Copy-Number Gain Is an Independent Prognostic Factor in Patients with Colorectal Cancer.
Kyu Sang Lee,Yoonjin Kwak,Kyung Han Nam,Duck-Woo Kim,Sung Bum Kang,Gheeyoung Choe,Woo Ho Kim,Hye Seung Lee +7 more
TL;DR: In this article, the authors determined the incidence and clinicopathological significance of c-MYC gene copy-number (GCN) gain in patients with primary colorectal cancer (CRC).
