BACKGROUND Metastatic breast cancer originating in the gastrointestinal tract is a rare occurrence. The limited number of cases has resulted in incomplete understanding of the disease, making it challenging to differentiate from primary breast cancer. While clinical history and immunohistochemical studies can aid in distinguishing between the two, the management principles and pathogenesis of gastrointestinal metastatic breast cancer remain controversial. The scarcity of data has hampered comprehensive knowledge. Our objective is to shed light on this rare disease through our case study. CASE SUMMARY Here, we report a case of breast metastasis from gastric cancer in a 43-year-old woman. This patient was admitted to our hospital with complaints of discomfort in the upper and middle abdomen persisting for two months, as well as black stools for over ten days. She underwent radical distal gastrectomy for gastric cancer, followed by postoperative chemotherapy. Three years later, the patient developed bilateral breast nodules. Imaging studies indicated a high probability of malignancy. She subsequently underwent a right modified radical mastectomy and excision of a left breast mass. Postoperative pathology revealed the right breast tumor was consistent with primary gastric cancer. CONCLUSION We present a case of breast metastasis from gastric cancer to contribute to the limited foundation of research into this rare disease.

BACKGROUND Little is known about disparities in diagnosis and treatment among colorectal cancer (CRC) patients with and without disabilities. AIM To investigate the patterns of diagnosis, treatment, and survival for people with and without disabilities who had CRC. METHODS We performed a retrospective analysis using the Korean National Health Insurance Service database, disability registration data, and Korean Central Cancer Registry data. The analysis included 21449 patients with disabilities who were diagnosed with CRC and 86492 control patients diagnosed with CRC. RESULTS The overall distribution of CRC stage was not affected by disability status. Subjects with disabilities were less likely than those without disabilities to undergo surgery [adjusted odds ratio (aOR): 0.85; 95% confidence interval (95%CI): 0.82-0.88], chemotherapy (aOR: 0.84; 95%CI: 0.81-0.87), or radiotherapy (aOR: 0.90; 95%CI: 0.84-0.95). The rate of no treatment was higher in patients with disabilities than in those without disabilities (aOR: 1.48; 95%CI: 1.41-1.55). The overall mortality rate was higher in patients with disabilities [adjusted hazard ratio (aHR): 1.24; 95%CI: 1.22-1.28], particularly severe disabilities (aHR: 1.57; 95%CI: 1.51-1.63), than in those without disabilities. CONCLUSION Patients with severe disabilities tended to have a late or unknown diagnosis. Patients with CRC and disabilities had lower rates of treatment with almost all modalities compared with those without disabilities. During the follow-up period, the mortality rate was higher in patients with disabilities than in those without disabilities. The diagnosis and treatment of CRC need improvement in patients with disabilities.

The publication by Qu et al provided a comprehensive discussion about the epidemiology, etiology, histopathology, early detection, and endoscopic treatment of esophageal carcinoma (EC) and summarized the progress in the advanced technologies for screening and endoscopic resection for EC. In this editorial, we will provide deeper insight into the challenges that hinder practical application of these advanced technologies along with the role of these technologies in upper endoscopy quality. More efforts need to be made to overcome the challenges and add the value of these technologies in upper endoscopy quality. Clinical outcomes of management strategies after noncurative endoscopic dissection for early EC patients need further investigation. The experiences with noncurative endoscopic resection of other organs may have certain implications for noncurative resection of early EC.

BACKGROUND Colorectal cancer (CRC) prognosis prediction is currently a major challenge. Epigenetic regulation has been widely reported for its role in cancer development. AIM To construct a robust prognostic signature, we used developed and validated across datasets. METHODS After constructing the signature, the prognostic value of the signature was evaluated in the TCGA cohort and six independent datasets (GSE17526, GSE17537, GSE33113, GSE37892, GSE39048 and GSE39582). The clinical, genomic and transcriptomic features related to the signature were identified. The correlations of the signature score with immune cell infiltration and cell-cell interactions were analyzed. The correlations between the signature score and the sensitivity to different drugs were also predicted. RESULTS In the TCGA cohort, patients in the low-risk group according to the signature score had longer survival than those in the high-risk group, and this finding was validated in the validation datasets. The signature was a prognostic factor independent of age and sex and was correlated with stage and PD-1 /PD-L1 expression. Area under the receiving operating characteristic curve was 0.72. Genomic association analyses revealed that samples from high-risk patients exhibited chromosomal instability. Transcriptomic analyses revealed that the signature score was significantly associated with multiple cellular pathways. Bulk RNA-seq and single-cell sequencing data revealed that the signature reflected differences in infiltrating immune cell-tumor cell interactions, especially for macrophages. The signature also predicted the putative drug sensitivity of CRC samples. CONCLUSION The signature is a valuable biomarker for predicting CRC prognosis and reflects multiple features of CRC, especially macrophage infiltration in the microenvironment.

BACKGROUND Esophageal carcinoma (EC) is one of the most prevalent cancers in human populations worldwide. Baitouweng decoction is one of the most important Chinese medicine formulas, with the potential to treat cancer. AIM To investigate the role and mechanism of Baitouweng decoction on EC cells. METHODS Differentially expressed genes (DEGs) in EC tissues and normal tissues were screened by the cDNA microarray technique and by bioinformatics methods. The target genes of microRNAs were predicted based on the TargetScan database and verified by dual luciferase gene reporter assay. We used Baitouweng decoction to intervene EC cells, and detected the activity of EC9706 and KYSE150 cells by the MTT method. Cell cycle and apoptosis were measured by flow cytometry. The expression of BUB1 mRNA and miR-495-3p was measured by qRT-PCR. The protein levels of BUB1, STAT3, p-STAT3, CCNB1, CDK1, Bax, Caspase3, and Caspase9 were measured by Western blot analysis. The migration and invasion abilities of the cells were measured by wound-healing assay and Transwell invasion assay, respectively. RESULTS DEGs identified are involved in biological processes, signaling pathways, and network construction, which are mainly related to mitosis. BUB1 was the key hub gene, and it is also a target gene of miR-495-3p. Baitouweng decoction could upregulate miR-495-3p and inhibit BUB1 expression. In vitro experiments showed that Baitouweng decoction significantly inhibited the migration and invasion of EC cells and induced apoptosis and G2/M phase arrest. After treatment with Baitouweng decoction, the expression of Bax, Caspase 3, and Caspase 9 in EC cells increased significantly, while the expression of BUB1, CCNB1, and CDK1 decreased significantly. Moreover, the STAT3 signaling pathway may play an important role in this process. CONCLUSION Baitouweng decoction has a significant inhibitory effect on EC cell growth. BUB1 is a potential therapeutic target for EC. Further analysis showed that Baitouweng decoction may inhibit the growth of EC cells by upregulating miR-495-3p targeting the BUB1-mediated STAT3 signal pathway.

BACKGROUND Adipocytes, especially adipocytes within tumor tissue known as cancer-associated adipocytes, have been increasingly recognized for their pivotal role in the tumor microenvironment of gastric cancer (GC). Their influence on tumor progression and patient prognosis has sparked significant interest in recent research. The main objectives of this study were to investigate adipocyte infiltration, assess its correlation with clinical pathological features, develop a prognostic prediction model based on independent prognostic factors, evaluate the impact of adipocytes on immune cell infiltration and tumor invasiveness in GC, and identify and validate genes associated with high adipocyte expression, exploring their potential diagnostic and prognostic value. AIM To explore the relationship between increased adipocytes within tumor tissue and prognosis in GC patients as well as the associated mechanisms and potential biomarkers, using public databases and clinical data. METHODS Using mRNA microarray datasets from the Gene Expression Omnibus database and clinical samples from Jiangsu Provincial Hospital, survival and regression analyses were conducted to determine the relevant prognostic factors in GC. Feature gene selection was performed using least absolute shrinkage and selection operator and support vector machine recursive feature elimination algorithms, followed by differential gene expression analysis, gene ontology, pathway analysis, and Gene Set Enrichment Analysis. Immune cell infiltration was analyzed using the CIBERSORT algorithm. RESULTS Tumor adipocyte infiltration correlated with poor prognosis in GC, leading to the development of a highly accurate and discriminative prognostic prediction model. Key genes, ADH1B , SFRP1 , PLAC9 , and FABP4 , were identified as associated with high adipocyte expression in GC. The diagnostic and prognostic potential of these identified genes was validated using independent datasets. Downregulation of immune cells was observed in GC with high adipocyte expression. CONCLUSION GC with high intratumoral adipocyte expression demonstrated aggressive tumor biology and a poorer prognosis. The genes ADH1B , SFRP1 , PLAC9 , and FABP4 have been identified as holding diagnostic and prognostic significance in GC. These findings strongly support the use of adipocyte expression as a valuable indicator of tumor invasiveness and anticipated patient outcomes in GC.

BACKGROUND The immune microenvironment (IME) in hepatocellular carcinoma (HCC) plays a pivotal role in determining patient outcomes and responses to treatment. This area is witnessing rapid growth in research interest. However, there is a lack of comprehensive bibliometric analyses that dissect trends and potential focal points in this field. AIM To explore the evolution of research on the IME in HCC from January 1, 2004, to December 31, 2023, using bibliometric methodologies. METHODS English articles and reviews concerning the IME of HCC were retrieved from the Web of Science Core Collection with a search date of December 31, 2023. The R package Bibliometrix was employed to compute basic bibliometric characteristics, illustrate collaborations among countries and authors, and create a three-field diagram illustrating the connections between authors, affiliations, and keywords. Analyses of country and institutional co-authorship, as well as keyword co-occurrence, were conducted using VOSviewer. Additionally, CiteSpace was utilized for the cite burst analysis of keywords and cited literature. RESULTS The study encompassed 3125 documents in the research areas related to HCC of IME, revealing a substantial and continuous increase in the annual publication trend over time. China and Fudan University emerged as leading contributors, with 2103 and 165 publications, respectively. Frontiers in immunology was the most prolific journal in this domain. Among the top ten researchers in the field, eight are based in China. Key research terms identified include tumour microenvironment, expression, immunotherapy, and prognosis. CONCLUSION The relationship between HCC and IME is receiving increasing attention, and related research is in a highly developed stage.

Macroautophagy (hereafter referred to as autophagy) is a prosurvival mechanism for the clearance of damaged cellular components, specifically related to exposure to various stressors such as starvation, excessive ethanol intake, and chemotherapy. This editorial reviews and comments on an article by Zhao et al , to be published in World J Gastrointestinal Oncology in 2024. Based on various molecular biology methodologies, they found that human β-defensin-1 reduced the proliferation of colon cancer cells, which was associated with the inhibition of the mammalian target of rapamycin, resulting in autophagy activation. The activation of autophagy is evidenced by increased levels of Beclin1 and LC3II/I proteins and mediated by the upregulation of long non-coding RNA TCONS_00014506. Our study discusses the impact of autophagy activation and mechanisms of autophagy, including autophagic flux, on cancer cells. Additionally, we emphasize the importance of describing the detailed methods for isolating long noncoding RNAs TCONS_00014506. Our review will benefit the scientific community and improve the overall clarity of the paper.

BACKGROUND Helicobacter pylori (H. pylori ) colonizes the human gastric mucosa and is implicated in the development of gastric cancer (GC). The tumor microenvironment is characterized by hypoxia, where hypoxia-inducible factor-1α (HIF-1α) plays a key role as a transcription factor, but the mechanisms underlying H. pylori -induced HIF-1α expression and carcinogenesis remain unclear. AIM To explore the underlying mechanism of H. pylori -induced HIF-1α expression in promoting the malignant biological behavior of gastric epithelial cells (GES-1). METHODS The study was conducted with human GES-1 cells in vitro . Relative protein levels of methyltransferase-like protein 14 (METTL14), HIF-1α, main proteins of the PI3K/AKT pathway, epithelial-mesenchymal transition (EMT) biomarkers, and invasion indicators were detected by Western blot. Relative mRNA levels of METTL14 and HIF-1α were detected by quantitative reverse transcription-polymerase chain reaction. mRNA stability was evaluated using actinomycin D, and the interaction between METTL14 and HIF-1α was confirmed by immunofluorescence staining. Cell proliferation and migration were evaluated by cell counting kit-8 assay and wound healing assay, respectively. RESULTS H. pylori promoted HIF-1α expression and activated the PI3K/AKT pathway. Notably, METTL14 was downregulated in H. pylori -infected gastric mucosal epithelial cells and positively regulated HIF-1α expression. Functional experiments showed that the overexpression of HIF-1α or knockdown of METTL14 enhanced the activity of the PI3K/AKT pathway, thereby driving a series of malignant transformation, such as EMT and cell proliferation, migration, and invasion. By contrast, the knockdown of HIF-1α or overexpression of METTL14 had an opposite effect. CONCLUSION H. pylori- induced underexpression of METTL14 promotes the translation of HIF-1α and accelerates tumor progression by activating the PI3K/AKT pathway. These results provide novel insights into the carcinogenesis of GC.
