Lee DK, Lee CK, Kim HS, Sym SJ, Zang DY, Kim KH, Lim JH, Kim HS, Lee KH, Gee HY, Rha SY, Kim H and Jung M
The nProfiler 1 Stomach Cancer Assay (nProfiler1), designed to predict responses to fluorouracil-based adjuvant chemotherapy, measures the expression of four gastric cancer target genes (GZMB, WARS, SFRP4, and CDX1). The randomized phase III POST trial aimed to compare the efficacies of two adjuvant S-1-based doublet chemotherapies: S-1 plus cisplatin (SP) and S-1 plus docetaxel (DS). This study aimed to validate the nProfiler1 assay using a distinct cohort from the POST trial.

Is Colonoscopy Alone Adequate for Surveillance in Stage I Colorectal Cancer?
Kim S, Shin JK, Park Y, Huh JW, Kim HC, Yun SH, Lee WY and Cho YB
While colonoscopy is the standard surveillance tool for stage I colorectal cancer according to NCCN guidelines, its effectiveness in detecting recurrence is debated. This study evaluates recurrence risk factors and patterns in stage I colorectal cancer to inform comprehensive surveillance strategies.

Higher Microbial Abundance and Diversity in Bronchus-Associated Lymphoid Tissue (BALT) Lymphomas than in Non-Cancerous Lung Tissues
Kim JH, Kim JS, Choi N, Koh J, Jeon YK, Chang JH, Hwang ES and Kim IH
It is well known that the majority of the extranodal marginal zone lymphomas of mucosa-associated lymphoid tissues (MALT lymphomas) are associated with microbiota, e.g., gastric MALT lymphoma with Helicobacter pylori. In general, they are very sensitive to low-dose radiotherapy and chemotherapeutic agents. The microbiota profile is not clearly elucidated in bronchus-associated lymphoid tissue (BALT) lymphoma, a rare type of MALT lymphoma in the lung. Thus, this study aimed to clarify the intratumor microbiome in BALT lymphoma using the third-generation NGS method.
