While oxaliplatin (L-OHP) is a potent chemotherapeutic agent that induces apoptosis in EC cells, its effectiveness is significantly hindered by the development of resistance.Materials and methods: The assessment of gene and protein expression was conducted through a combination of RT-qPCR, Western blot, and IHC staining. Cell viability was assessed using the CCK-8 assay. The interactions among ALYREF, TBL1XR1, KMT2E, and APOC1 were investigated through RIP, ChIP, ChIP-reChIP, RNA pulldown, and dual-luciferase assays. An in vivo mouse model of EC was established.Results: Expression levels of both APOC1 and ALYREF were elevated in L-OHP-resistant EC tissues and cell lines, and their silencing enhanced sensitivity to L-OHP. TBL1XR1 and KMT2E synergistically upregulated APOC1 expression. Moreover, ALYREF recognized the m5C sites on TBL1XR1 and KMT2E mRNAs, stabilizing these transcripts and promoting APOC1 expression. The regulatory role of these interactions was further validated in vivo.Conclusion: This study demonstrated that ALYREF interacted with the m5C sites on TBL1XR1 and KMT2E mRNAs, enhancing their stability and leading to increased transcription of APOC1, which in turn contributed to L-OHP resistance in EC. These findings suggest that targeting APOC1 could be a promising strategy for overcoming L-OHP resistance in EC.","PeriodicalId":49094,"journal":{"name":"Cancer Research and Treatment","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143123906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given a potential interaction between alcohol's insulin-sensitizing effect and hyperglycemia-related insulin resistance, we aimed to assess whether the dose-response association between alcohol intake and kidney cancer risk varies based on glycemic status.Materials and methods: This nationwide cohort study analyzed data from 9,492,331 adults who underwent a national health screening program in 2009 and were followed until 2018. Multivariable-adjusted Cox regression models were applied to estimate the hazard ratios (aHRs) and 95% confidence intervals (CIs).Results: Over a median follow-up period of 8.3 years, 12,381 participants were diagnosed with kidney cancer. A U-shaped relationship between alcohol consumption and kidney cancer risk was observed among individuals with normoglycemia (light-to-moderate; HR, 0.94; 95% CI, 0.89-0.99 and heavy; HR, 1.00; 95% CI, 0.91-1.09, respectively). In prediabetic individuals, alcohol consumption was not significantly associated with kidney cancer risk. In individuals with diabetes, a dose-dependent increase in kidney cancer risk was noted with higher alcohol consumption (light-to-moderate consumption: HR, 1.12; 95% CI, 1.03-1.22; heavy consumption: HR, 1.24; 95% CI, 1.09-1.42; P for trend <0.01).Conclusion: A modest U-shaped dose-response association between alcohol consumption and kidney cancer risk was observed exclusively in individuals with normoglycemia. Individuals with diabetes demonstrated a dose-dependent increased risk of kidney cancer with higher alcohol consumption. Tailored patient education and personalized risk assessments regarding alcohol consumption and kidney cancer risk should be emphasized over a generalized 'one-size-fits-all' approach.","PeriodicalId":49094,"journal":{"name":"Cancer Research and Treatment","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143123926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, we aimed to develop a risk assessment tool for breast cancer in Asian women using a nationwide, population-based mammographic screening cohort.Materials and methods: Women aged ≥40 years who underwent breast cancer screening and general health examination in 2009 were included. Age, body mass index (BMI), breast density, lifestyle and reproductive factors, and comorbidities were used to develop 5-year breast cancer risk-prediction models for premenopausal (n=771,856) and postmenopausal (n=1,108,047) women at baseline. The best-fit risk prediction model was constructed using backward stepwise selection in a Cox proportional hazards model and was transformed into a risk score nomogram. The performance was assessed by discrimination and calibration.Results: In premenopausal women, high BMI, low parity, short breastfeeding period, early age at menarche, high breast density, a history of benign breast masses, and family history of breast cancer contributed to the risk prediction of breast cancer. In postmenopausal women, age, diabetes mellitus, dyslipidemia, late-onset menopause, and hormone replacement therapy use were additional risk predictors of breast cancer. Our risk-prediction model showed a concordant statistic of 0.58 (0.57-0.59) for premenopausal women and 0.64 (0.63-0.65) for postmenopausal women. The calibration plot demonstrated good correlations for both models.Conclusion: Our breast cancer risk-prediction model demonstrated performance comparable to that of Western countries, especially among postmenopausal women.

This analysis focuses on the PIK3CAɑ inhibitor alpelisib (arm 1) in patients with phosphoinositide 3-kinase (PI3K) pathway alterations.Materials and methods: Patients with PI3K pathway altered tumors were enrolled in the alpelisib arm of the TRIUMPH study. We conducted a detailed analysis of the correlation between PI3K pathway mutations and treatment outcomes including disease control rate (DCR), overall survival (OS), and progression-free survival (PFS).Results: From Oct 2017 and Aug 2020, 203 were enrolled, with 42 treated with alpelisib. Response evaluation was possible for 33 patients. Genomic profiles revealed PIK3CA amplifications in 26.2%, and point mutations in E542K (26.2%), E545K (23.8%), and H1047R (9.5%). Neither PIK3CA amplification nor co-occurring TP53 mutations had a notable influence on alpelisib response or survival outcomes. Although the overall response rates were similar between helical domain mutations (E542, E545) and kinase domain mutations (H1047), patients with H1047 mutations exhibited significantly poorer PFS compared to those with non-H1047 PIK3CA alterations (1.6 vs. 7.3 months, p=0.017). OS in patients with H1047 kinase domain mutations showed a trend toward being shorter compared to others, though this difference did not reach statistical significance.Conclusion: Alpelisib showed differential efficacy based on PI3K pathway alterations in patients with R/M HNSCC and was well-tolerated. These findings suggest the usefulness of NGS testing-based decision-making when using the targeted agents in R/M HNSCC.

Our purpose was to investigate the effects of clinical and pathological factors on tumor recurrence, death, and prognosis across various metastasizing pathways.Materials and methods: Our study group included 335 patients with all demographic and pathologic data available who underwent surgical resection for lung adenocarcinoma for more than 10 years. The following states of disease were defined: initial state, operation (OP); three intermediate states of local recurrence (LR), metastasis (Meta), and concurrent LR with metastasis (LR+Meta); and a terminal state, death. We identified 8 transitions representing various pathways of tumor progression. We employed a multi-state model (MSM) to separate the impacts of multiple prognostic factors on the transitions following surgery.Results: After surgery, approximately half of patients experienced recurrence. Specifically, 142 (42.4%), 54 (16.1%), and 7 (2.1%) patients developed Meta, LR+Meta, and LR, respectively. Clinical and pathological factors associated with the transitions were different. Impact of pathological lymph node remained a risk factor for both OP to Meta (λ02, p-value=0.001) and OP to LR+Meta (λ03, p-value = 0.001).Conclusion: Lung adenocarcinoma displays a broad spectrum of clinical scenarios even after curative surgery. Incidence, risk factors, and prognosis varied across different pathways of recurrence in lung adenocarcinoma patients. The greatest implication of this MSM is its ability to predict the timing and type of clinical intervention that will have the greatest impact on survival.","PeriodicalId":49094,"journal":{"name":"Cancer Research and Treatment","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143123981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to develop a gene signature for the stratification of high-risk pediatric AML using publicly available AML datasets, with a focus on literature-based prognostic gene sets.Materials and methods: We identified 300 genes from 12 well-validated studies on AML-related gene signatures. Clinical and gene expression data were obtained from three datasets: TCGA-LAML, TARGET-AML, and BeatAML. Least absolute shrinkage and selection operator (LASSO)-Cox regression analysis was used to perform the initial gene selection and to construct a prognostic model using the TCGA database (n=132). The final gene signature was validated with two independent cohorts: BeatAML (n=411) and TARGET-AML (n=187).Results: We identified a six-gene signature (ETFB, ARL6IP5, PTP4A3, CSK, HS3ST3B1, PLA2G4A), referred to as the literature-based signature 6 (LBS6), that was significantly associated with lower overall survival rates across the TCGA (HR=4.2, 95% CI: 2.59-6.81, p<0.0001), BeatAML (HR=1.52, 95% CI: 1.17-1.96, p=0.0013), and TARGET (HR=2.05, 95% CI: 1.36-3.08, p<0.001) datasets. The high-LBS6 score group exhibited significantly poorer five-year event-free survival compared to the low-LBS6 score group (HR=2.09, 95% CI: 1.38-3.15, p<0.001). After adjusting for key risk factors, including gene mutations (WT1, FLT3, and NPM1), protocol-based risk group, WBC count, and age, the LBS6 score was independently associated with worse survival rates in validation cohorts.Conclusion: Our literature-driven approach identified a robust gene signature that stratifies AML patients into distinct risk groups.

In Asia, particularly in Korea, D2 gastrectomy followed by adjuvant chemotherapy has been established as the standard treatment for stage II/III gastric cancer based on landmark clinical trials. However, this \"one-size-fits-all\" approach requires refinement as emerging evidence suggests heterogeneous outcomes even within the same stage. This review discusses the evolving landscape of adjuvant treatment in gastric cancer, emphasizing the transition towards precision medicine. Recent molecular characterization of gastric cancer has revealed distinct subtypes with varying prognoses and chemotherapy responses, exemplified by the favorable outcomes of microsatellite instability-high tumors without adjuvant chemotherapy. Additionally, clinical factors including sub-stages within stage II/III, patient performance status, comorbidities, and personal preferences should be considered in treatment decisions. The integration of these molecular and clinical factors, along with shared decision-making between physicians and patients, represents a crucial step toward personalized treatment approaches. Looking ahead, the field is poised for further evolution with the emergence of immune checkpoint inhibitors, growing evidence for neoadjuvant chemotherapy in selected cases, and the potential of circulating tumor DNA as a biomarker for minimal residual disease. This comprehensive approach to treatment decision-making, considering both tumor biology and patient factors, will be essential for realizing precision medicine in gastric cancer care.","PeriodicalId":49094,"journal":{"name":"Cancer Research and Treatment","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143123980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Importantly, cell lines, clinical samples (52 patients in surgery cohort and 36 in immunotherapy cohort), animal models, RNA-seq, experiments in protein and mRNA levels were conducted for identifying and validating key biomarker in LUAD immunotherapy.Results: A prognostic signature comprising 33 LMRGs was developed and validated as an effective predictor of prognosis and TIME, with a C-index of 0.766 (95% CI: 0.729-0.804). Additionally, we identified Acyl-CoA Synthetase Long Chain Family Member 3 (ACSL3) as a potential biomarker for immunotherapy prognosis.

This study aimed to investigate the role of Ninj1 in colitis-associated colorectal cancer (CRC) by focusing on its interaction with 17β-estradiol (E2).Materials and methods: Using an azoxymethane (AOM)/dextran sodium sulfate (DSS) mouse model of colitis-associated CRC, wild-type (WT) and Ninj1 knockout (KO) male mice were treated with or without E2.Results: At week 2, Ninj1 KO mice exhibited attenuated colitis symptoms than WT mice following AOM/DSS treatment. E2 administration significantly alleviated these symptoms in both WT and Ninj1 KO mice, with reductions in the disease activity index (DAI), colon length shortening, and histopathological damage. The levels of pro-inflammatory mediators were reduced by E2 treatment in both groups, with the Ninj1 KO group showing a more pronounced response. At week 13, tumor development in Ninj1 KO mice was significantly lower than that in WT mice, particularly in the distal colon. E2 treatment inhibited tumor formation in WT mice and had a stronger inhibitory effect on distal colon tumorigenesis in Ninj1 KO mice. Immune cell populations, including the populations of macrophages and T cells, were also modulated by E2 in WT mice; however, these effects were diminished in Ninj1 KO mice.Conclusion: These findings suggest that Ninj1 plays a role in modulating colitis and CRC progression, with E2 exerting anti-inflammatory and anti-tumorigenic effects that are influenced by Ninj1 status.","PeriodicalId":49094,"journal":{"name":"Cancer Research and Treatment","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142985152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
