Abstract
Within the intricate milieu of colorectal cancer (CRC) tissues, cancer-associated fibroblasts (CAFs) act as pivotal orchestrators, wielding considerable influence over tumor progression. This review endeavors to dissect the multifaceted functions of CAFs within the realm of CRC, thereby highlighting their indispensability in fostering CRC malignant microenvironment and indicating the development of CAFs-targeted therapeutic interventions. Through a comprehensive synthesis of current knowledge, this review delineates insights into CAFs-mediated modulation of cancer cell proliferation, invasiveness, immune evasion, and neovascularization, elucidating the intricate web of interactions that sustain the pro-tumor metabolism and secretion of multiple factors. Additionally, recognizing the high level of heterogeneity within CAFs is crucial, as they encompass a range of subtypes, including myofibroblastic CAFs, inflammatory CAFs, antigen-presenting CAFs, and vessel-associated CAFs. Innovatively, the symbiotic relationship between CAFs and the intestinal microbiota is explored, shedding light on a novel dimension of CRC pathogenesis. Despite remarkable progress, the orchestrated dynamic functions of CAFs remain incompletely deciphered, underscoring the need for continued research endeavors for therapeutic advancements in CRC management.

Lv L, Song YH, Gao Y, Pu SQ, A ZX, Wu HF, Zhou J, Xie YC. Signet-ring cell carcinoma of the transverse colon in a 10-year-old girl: A case report. World J Gastrointest Oncol 2024; 16:4746-4752. [DOI: 10.4251/wjgo.v16.i12.4746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2024] [Revised: 09/29/2024] [Accepted: 10/18/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND Signet-ring cell carcinoma (SRCC) is a rare subtype of colorectal cancer. The incidence of primary colonic SRCC is relatively rare in pediatric patients, with a limited number of reported cases currently available. The prognosis for this specific tumor type is unfavorable, and the preoperative diagnosis presents challenges, potentially leading to misdiagnosis. This case report describes the diagnosis of primary SRCC in the colon of a 10-year-old girl.
CASE SUMMARY The patient was admitted to the hospital due to abdominal pain and vomiting. A computed tomography scan revealed an irregular mass with soft tissue density in her transverse colon, showing uneven density and multiple calcifications. The patient underwent surgical resection of the affected bowel and lymph node dissection, which was confirmed by pathological examination to be SRCC infiltrating both nerves and the entire intestinal wall. Additionally, tumor thrombus formation was observed in blood vessels and lymphatic vessels, multiple cancerous nodules were found in the omentum, and metastasis to 18 of 26 mesenteric lymph nodes examined. Immunohistochemistry for mismatch repair gene protein demonstrated microsatellite stability. No mutations in KRAS, NRAS, BRAF, or PIK3CA genes were detected through molecular pathology analysis. After surgery, she received standard chemotherapy for 8 cycles without tumor progression or other abnormalities during a 12-month follow-up period.
CONCLUSION Primary colonic SRCC is a rare malignant tumor with atypical clinical symptoms, and timely identification and intervention are crucial for improving the prognosis.

Abstract
Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare mixed tumors containing both neuroendocrine and non-neuroendocrine components that occupy at least 30% of the whole tumor. Biologically, both components appear to derive from an identical cellular precursor undergoing early dual differentiation or late transdifferentiation. While our understanding of MiNENs has improved in recent years, many areas of uncertainty remain. In this context, setting diagnostic criteria capable of capturing the continuum of disease biology while providing clinically meaningful information in terms of prognosis and response to treatments appears vital to advance the field and improve patients’ outcomes. Evidence is needed to generate robust classification schemes, and multi-institutional cooperation will likely play a crucial role in building adequately powered cohorts to address some of the most pressing questions discussed in this Editorial. What is the minimum representation for each component needed to define MiNENs? How can the epidemiology of MiNENs change according to different diagnostic definitions? How can we generate the clinical evidence needed to optimize the management of MiNENs?

Efficacy and safety of transhepatic arterial chemoembolization with drug-loaded microspheres in unresectable primary liver cancer. World J Gastrointest Oncol 2024; 16:4728-4737. [DOI: 10.4251/wjgo.v16.i12.4728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 08/11/2024] [Accepted: 08/20/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND Transhepatic arterial chemoembolization (TACE), as a local treatment, has been widely used in the treatment of unresectable liver cancer. The introduction of drug carrier microspheres has brought new hope for the therapeutic effect of TACE. Microspheres can realize the slow release and directional delivery of drugs, reduce systemic toxicity and improve local curative effect.
AIM To compare the effectiveness of traditional transcatheter arterial chemoembolization against microsphere-assisted transcatheter arterial chemoembolization in the treatment of hepatocellular carcinoma that is incurable.
METHODS We searched the PubMed, Embase, Cochrane Library, and CNKI databases for clinical trials of drug-luting beads TACE (DEB-TACE) vs conventional TACE (cTACE) for the treatment of unresectable liver cancer. We screened references based on inclusion and exclusion criteria and then selected valid data for meta-analysis using RevMan 53 software. The complete response (CR) rate, partial response (PR) rate, postoperative stable disease (SD) rate, and 6-month and 12-month survival rates were compared.
RESULTS A total of 12 articles were included, including 1177 patients, 519 of whom received DEB-TACE and 658 of whom received cTACE. The CR rate in the DEB-TACE group was much greater than that in the cTACE group [relative risk (RR) = 1.42, 95%CI: 1.18–1.72, P = 0.0002]. The 12-month survival rate significantly increased (RR = 1.09; 95%CI: 1.01- 1.17, P = 0.03); the PR rate (RR = 1.13; 95%CI: 0.97-1.30, P = 0.12); the SD rate (RR = 0.82; 95%CI: 0.64-1.05, P = 0.12); and the 6-month survival rate (RR = 1.05; 95%CI: 1.00-1.10, P = 0.07). There was no significant difference (P < 0.05).
CONCLUSION Compared with those of iodized oil TACE, the drug-loaded microspheres tended to have therapeutic advantages.

[DOI: 10.4251/wjgo.v16.i12.4738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 10/05/2024] [Accepted: 10/22/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND Pancreatic mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are rare malignancies affecting the pancreas. The World Health Organization defines MiNENs as neoplasms composed of morphologically recognizable neuroendocrine and non-neuroendocrine components, each constituting 30% or more of the tumor volume. Adenocarcinoma-neuroendocrine carcinoma is the most frequent MiNEN combination. A well-differentiated neuroendocrine tumor (NET) component is rarely reported in MiNENs.
CASE SUMMARY Here we report a rare case with intermingled components of ductal adenocarcinoma and grade 1 well-differentiated NET in the pancreas. The two tumors show distinct histology and significant differentiation discrepancy (poorly differentiated high grade adenocarcinoma and well-differentiated low grade NET), and also present as metastases in separate lymph nodes. Next generation sequencing of the two components demonstrates KRAS and TP53 mutations in the ductal adenocarcinoma, but no genetic alterations in the NET, suggesting divergent origins for these two components. Although tumors like this meet the diagnostic criteria for MiNEN, clinicians often find the diagnosis and staging confusing and impractical for clinical management.
CONCLUSION Mixed NET/non-NET tumors with distinct histology and molecular profiles might be better classified as collision tumors rather than MiNENs.

Prognostic utility of gamma-glutamyl transpeptidase to platelet ratio in patients with solitary hepatitis B virus-related hepatocellular carcinoma after hepatectomy. World J Gastrointest Oncol 2024; 16:4579-4596. [DOI: 10.4251/wjgo.v16.i12.4579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 09/12/2024] [Accepted: 09/29/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND The prognostic impact of preoperative gamma-glutamyl transpeptidase to platelet ratio (GPR) levels in patients with solitary hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) following radical resection has not been established.
AIM To examine the clinical utility of GPR for prognosis prediction in solitary HBV-related HCC patients.
METHODS A total of 1167 solitary HBV-related HCC patients were retrospectively analyzed. GPR levels were compared with 908 non-HCC individuals. Overall survival (OS) and recurrence-free survival (RFS) were evaluated, and cox proportional hazard model analyses were performed to identify independent risk factors. Differences in characteristics were adjusted by propensity score matching (PSM). Subgroup and stratified survival analyses for HCC risks were performed, and a linear trend of the hazard ratio (HR) according to GPR levels was constructed.
RESULTS GPR levels of patients with solitary HBV-related HCC were higher than those with hepatic hemangiomas, chronic hepatitis B and healthy control (adjusted P < 0.05). Variable bias was diminished after the PSM balance test. The low GPR group had improved OS (P < 0.001) and RFS (P < 0.001) in the PSM analysis and when combined with other variables. Multivariate cox analyses suggested that low GPR levels were associated with a better OS (HR = 0.5, 95%CI: 0.36-0.7, P < 0.001) and RFS (HR = 0.57, 95%CI: 0.44-0.73, P < 0.001). This same trend was confirmed in subgroup analyses. Prognostic nomograms were constructed and the calibration curves showed that GPR had good survival prediction. Moreover, stratified survival analyses found that GPR > 0.6 was associated with a worse OS and higher recurrence rate (P for trend < 0.001).
CONCLUSION Preoperative GPR can serve as a noninvasive indicator to predict the prognosis of patients with solitary HBV-related HCC.

World J Gastrointest Oncol 2024; 16:4700-4715. [DOI: 10.4251/wjgo.v16.i12.4700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2024] [Revised: 09/17/2024] [Accepted: 10/16/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND The 5-year survival rate of patients with colorectal cancer (CRC) in China is only 56.9%, highlighting the need for new therapeutic drugs. Previous studies have shown that matrine exhibits antitumor effects by inducing apoptosis. However, the mechanism by which matrine regulates antiapoptotic proteins in CRC remains unclear.
AIM To identify apoptotic proteins from proteomics and investigate the role of matrine in impeding CRC apoptosis by regulating these proteins.
METHODS Tumor and adjacent normal tissues were collected from 52 patients with CRC who underwent surgery between January and December 2021. Data-independent acquisition quantitative proteomic analysis was performed to identify differentially expressed apoptotic proteins. The selected apoptotic proteins were identified through their association with tumor-node-metastasis (TNM) stage and prognosis, then confirmed by immunohistochemical (IHC) staining in validation cohort. In vitro, the role of matrine or apoptotic proteins on cancer cells were analyzed.
RESULTS Compared to normal tissues, 88 anti-apoptotic proteins from proteomic results were selected. Among them, Shank-associated RH domain interactor (SHARPIN) was identified because of its relationship with TNM stage and overall survival in TCGA database. In the IHC-confirmed cohort, SHARPIN was highly expressed in CRC tissues and localized in the cytoplasm. Higher SHARPIN expression was associated with TNM stage, carbohydrate antigen 153 levels, and gross type compared to low expression. SHARPIN knockdown promoted apoptosis, significantly upregulated the expression of Bcl-2 associated agonist of cell death, Bcl-2 associated X protein, caspase 3, and caspase 8, and downregulated B-cell lymphoma-2 (P < 0.05). Importantly, matrine treatment promoted apoptosis and reversed the proliferation, invasion, and migration of CRC cells by repressing SHARPIN.
CONCLUSION SHARPIN was identified as an upregulated anti-apoptotic protein in CRC, and matrine exhibited anticancer effects by downregulating its expression. Thus, matrine appears to be a promising drug for CRC.

Abstract
Newer systemic therapies for hepatocellular carcinoma (HCC) have led to growing interest in combining hepatic arterial infusion chemotherapy (HAIC) with systemic treatments. To evaluate the effectiveness and safety of HAIC and combination therapies in treating advanced HCC, a network meta-analysis was conducted by Zhou et al. The study included data from 44 articles. HAIC was superior in overall survival (OS), progression-free survival (PFS), and response rates compared to transarterial chemoembolization and sorafenib. Moreover, combinations of HAIC with other treatments and single agents (e.g., lenvatinib, ablation, anti-programmed cell death 1 therapy, radiotherapy) provided better OS and PFS outcomes than HAIC alone. In this editorial, we will discuss the study findings, the strengths and weaknesses of the metanalysis, and future advances in the field of HAIC for advanced HCC.

Abstract
Colorectal cancer (CRC) ranks third in the number of cancers mainly because of the inability to diagnose it at an early stage. The pathogenesis of CRC is complicated, which is the result of the complex interaction of multiple genetic and environmental factors. Currently, one of the main treatments for CRC is chemotherapy. But the primary cause of CRC treatment failure is drug resistance. The expression of cyclin-dependent kinase 9 (CDK9) was correlated with elevated autophagy levels in colon cancer, and high expression of CDK9 indicates a poor prognosis in CRC. The incidence of autophagy and the expressions of Beclin 1 and ATP binding cassette transporter G2 are different in left and right colon cancer, and autophagy may be involved in the occurrence of chemotherapy resistance. In this article, the roles of CDK9, ATP binding cassette transporter G2 and Beclin 1 in CRC were elucidated, emphasizing the linkages among them and providing potential therapeutic targets of CRC.

Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. Major treatments include liver transplantation, resection, and chemotherapy, but the 5-year recurrence rate remains high. Late diagnosis often prevents surgical intervention, contributing to poor patient survival rates. Carcinogenesis in HCC involves genetic alterations that drive the transformation of normal cells into malignant ones. Enhancer of zeste homolog 2 (EZH2), a key regulator of cell cycle progression, is frequently upregulated in HCC and is associated with advanced stages and poor prognosis, making it a potential biomarker. Additionally, signal transducer and activator of transcription 3, which binds to EZH2, affects disease staging and outcomes. Targeting EZH2 presents a promising therapeutic strategy. On the other hand, abnormal lipid metabolism is a hallmark of HCC and impacts prognosis. Fatty acid binding protein 5 is highly expressed in HCC tissues and correlates with key oncogenes, suggesting its potential as a biomarker. Other genes such as guanine monophosphate synthase, cell division cycle associated 5, and epidermal growth factor receptor provide insights into the molecular mechanisms of HCC, offering potential as biomarkers and therapeutic targets.

Abstract
BACKGROUND Colorectal cancer (CRC) is characterized by high heterogeneity, aggressiveness, and high morbidity and mortality rates. With machine learning (ML) algorithms, patient, tumor, and treatment features can be used to develop and validate models for predicting survival. In addition, important variables can be screened and different applications can be provided that could serve as vital references when making clinical decisions and potentially improving patient outcomes in clinical settings.
AIM To construct prognostic prediction models and screen important variables for patients with stage I to III CRC.
METHODS More than 1000 postoperative CRC patients were grouped according to survival time (with cutoff values of 3 years and 5 years) and assigned to training and testing cohorts (7:3). For each 3-category survival time, predictions were made by 4 ML algorithms (all-variable and important variable-only datasets), each of which was validated via 5-fold cross-validation and bootstrap validation. Important variables were screened with multivariable regression methods. Model performance was evaluated and compared before and after variable screening with the area under the curve (AUC). SHapley Additive exPlanations (SHAP) further demonstrated the impact of important variables on model decision-making. Nomograms were constructed for practical model application.
RESULTS Our ML models performed well; the model performance before and after important parameter identification was consistent, and variable screening was effective. The highest pre- and postscreening model AUCs 95% confidence intervals in the testing set were 0.87 (0.81-0.92) and 0.89 (0.84-0.93) for overall survival, 0.75 (0.69-0.82) and 0.73 (0.64-0.81) for disease-free survival, 0.95 (0.88-1.00) and 0.88 (0.75-0.97) for recurrence-free survival, and 0.76 (0.47-0.95) and 0.80 (0.53-0.94) for distant metastasis-free survival. Repeated cross-validation and bootstrap validation were performed in both the training and testing datasets. The SHAP values of the important variables were consistent with the clinicopathological characteristics of patients with tumors. The nomograms were created.
CONCLUSION We constructed a comprehensive, high-accuracy, important variable-based ML architecture for predicting the 3-category survival times. This architecture could serve as a vital reference for managing CRC patients.

Abstract
BACKGROUND The development of tumor is closely linked to inflammation. Therefore, targeting molecules involved in inflammation may be effective in predicting cancer prognosis. Transarterial chemoembolization (TACE) holds significant therapeutic significance in addressing hepatocellular carcinoma (HCC). At present, no studies have evaluated the predictive value of γ-glutamyl transferase to albumin ratio (GAR) on the prognosis of HCC undergoing TACE.
AIM To explore the potential prognostic significance of the GAR in individuals undergoing TACE for HCC.
METHODS A total of 1231 patients from seven hospitals in China were randomized into a training cohort (n = 862) and a validation cohort (n = 369). To establish independent prognostic factors for overall survival (OS), we utilized multivariate and univariate Cox regression models. The best cut-off value of the GAR was determined with the X-tile software, with OS as the basis. Validations were performed using dual therapy cohort and triple therapy cohort.
RESULTS X-tile software revealed a GAR threshold of 4.75 as optimal. Both pre- and post-propensity score matching analyses demonstrated that the median OS in the low-GAR group (< 4.75) was notably longer compared to the high-GAR group (≥ 4.75), showing results of 26.9 vs 9.8 months (P < 0.001) initially, and 18.1 vs 11.3 months (P < 0.001) after match. Furthermore, multivariate analysis identified GAR ≥ 4.75 as an independent prognostic factor (P < 0.001). The receiver operating characteristic curves for the nomogram showed area under receiver operating characteristic curves of 0.741, 0.747, and 0.708 for predicting 1-, 2-, and 3-year survival, respectively. Consistent findings were reiterated in the two cohorts involving TACE in combination with targeted therapy and TACE in combination with targeted therapy and immunotherapy. Calibration curve and decision curve analyses substantiated the model’s relatively robust predictive capabilities.
CONCLUSION Our study validates the effective prognostic capacity of the GAR-based nomogram for HCC patients undergoing TACE or TACE in combination with systemic therapy.

Abstract
Hepatocellular carcinoma (HCC) is a lethal disease and unfortunately, most patients will be diagnosed with unresectable/advanced stages and the overall prognosis is poor. For patients with initially unresectable HCC (uHCC), transarterial chemoembolization (TACE) was the mainstream treatment. Lately, the incorporation of immune checkpoint inhibitors and antiangiogenics for the treatment of metastatic disease has paved the way for significant improvements in the treatment of initially uHCC. In this editorial we will discuss an article that evaluated ICI combinations with lenvatinib and TACE for the treatment of uHCC patients, and highlight future advances in the field.

World J Gastrointest Oncol 2024; 16:4559-4564. [DOI: 10.4251/wjgo.v16.i12.4559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2024] [Revised: 09/25/2024] [Accepted: 10/18/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
Mixed neuroendocrine non-neuroendocrine neoplasms constitute rare tumors that are located mainly in the gastrointestinal (GI) tract and have high degrees of malignancy, and the frequency of these tumors has been increasing. They consist of a neuroendocrine neoplastic component with another component of adenocarcinoma usually and have a dismal prognosis. The rare GI pure neuroendocrine carcinoma is highly aggressive and requires complex and extensive management since a genetic distinction exists between it and GI non-neuroendocrine neoplasms, which are generally slow-growing lesions. The most common GI-mixed neuroendocrine non-neuroendocrine neoplasms are colorectal, followed by gastric, mainly in the gastroesophageal junction. Current imaging modalities of nuclear medicine and radiology play important roles in the accuracy of diagnosis. Liquid biopsy may contribute to early detection and timely diagnosis. Ultrasonography, either endoscopic or abdominal, is a technique that contributes to a diagnosis; additionally, contrast-enhanced ultrasonography is very helpful in follow-up appointments. Histopathology establishes a definite diagnosis and stage by evaluating the cell differentiation grade and the cell proliferation index Ki67. The genetic profile can be valuable in diagnosis and gene therapy. Surgical resection with wide lymphadenectomy, whenever possible, and adjuvant chemotherapy constitute the main therapeutic management strategies. Targeted therapy and immunotherapy achieve encouraging results.

Abstract
Hepatocellular carcinoma (HCC) remains a major challenge in oncology, being a leading cause of cancer-related mortality worldwide. Early-stage HCC is typically treated with surgical resection, transplantation, or ablation, while advanced-stage HCC relies on systemic therapies like sorafenib and newer combinations such as atezolizumab-bevacizumab. Despite these advancements, there is still a need for effective treatments for unresectable HCC, especially in cases with macroscopic vascular invasion. Hepatic arterial infusion chemotherapy (HAIC) has demonstrated promising outcomes in Asia for the treatment of unresectable HCC, yet its application in Western countries has been relatively limited. This letter reviews the recent meta-analysis by Zhou et al published in the World Journal of Gastrointestinal Oncology, which demonstrates the efficacy and safety of HAIC vs sorafenib. The analysis includes 9 randomized controlled trials and 35 cohort studies, highlighting significant improvements in overall survival, progression-free survival, and objective response rates with HAIC and its combinations. The editorial explores the reasons behind the limited use of HAIC in Western countries. It underscores the potential of HAIC to enhance treatment outcomes for advanced HCC and calls for more research and broader adoption of HAIC in clinical practice globally.

Zhou DQ, Liu JY, Zhao F, Zhang J, Liu LL, Jia JR, Cao ZH. Risk factors for hepatocellular carcinoma in cirrhosis: A comprehensive analysis from a decade-long study. World J Gastrointest Oncol 2024; 16:4625-4635. [DOI: 10.4251/wjgo.v16.i12.4625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 08/28/2024] [Accepted: 10/09/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND Cirrhosis is a significant risk factor for the development of hepatocellular carcinoma (HCC). Variability in HCC risk among patients with cirrhosis is notable, particularly when considering the diverse etiologies of cirrhosis.
AIM To identify specific risk factors contributing to HCC development in patients with cirrhosis.
METHODS This retrospective study analyzed data from cirrhotic patients at Beijing Youan Hospital from January 1, 2012 to September 30, 2022 with at least 6 mo of follow-up. Patient demographics, medical histories, etiologies, and clinical characteristics were examined. Cox regression analysis was used to analyze correlations of the above parameters with hepatocarcinogenesis, while competing risk regression was used to estimate their adjusted hazard ratios accounting for death. The cumulative incidence was plotted over time.
RESULTS Overall, 5417 patients with cirrhosis (median age: 54 years; 65.8% males) were analyzed. Hepatitis B virus (HBV) was the most common etiology (23.3%), with 25% (n = 1352) developing HCC over a 2.9-year follow-up period. Patients with multiple etiologies had the HCC highest incidence (30.3%), followed by those with HBV-related cirrhosis (29.5%). Significant risk factors included male sex, advanced age, hepatitis C virus (HCV) infection, elevated blood ammonia, and low platelet count. Men had a higher 5-year HCC risk than women (37.0% vs 31.5%). HBV, HCV, and HBV/HCV co-infected patients had 5-year risks of HCC of 45.8%, 42.9%, and 48.1%, respectively, compared to 29.5% in nonviral hepatitis cases, highlighting the significant HCC risk from viral hepatitis, especially HBV, and underscores the importance of monitoring these high-risk groups.
CONCLUSION In conclusion, HBV-related cirrhosis strongly correlates with HCC, with male sex, older age, viral hepatitis, elevated blood ammonia, and lower albumin and platelet levels increasing the risk of HCC.

Abstract
Survival rates following radical surgery for gastric neuroendocrine neoplasms (g-NENs) are low, with high recurrence rates. This fact impacts patient prognosis and complicates postoperative management. Traditional prognostic models, including the Cox proportional hazards (CoxPH) model, have shown limited predictive power for postoperative survival in gastrointestinal neuroectodermal tumor patients. Machine learning methods offer a unique opportunity to analyze complex relationships within datasets, providing tools and methodologies to assess large volumes of high-dimensional, multimodal data generated by biological sciences. These methods show promise in predicting outcomes across various medical disciplines. In the context of g-NENs, utilizing machine learning to predict survival outcomes holds potential for personalized postoperative management strategies. This editorial reviews a study exploring the advantages and effectiveness of the random survival forest (RSF) model, using the lymph node ratio (LNR), in predicting disease-specific survival (DSS) in postoperative g-NEN patients stratified into low-risk and high-risk groups. The findings demonstrate that the RSF model, incorporating LNR, outperformed the CoxPH model in predicting DSS and constitutes an important step towards precision medicine.

Abstract
Gastric cancer (GC) remains a formidable global health concern with significant morbidity and mortality rates, despite the fact that numerous advances have been made to improve conventional therapies. Xiaojianzhong decoction (XJZ), a traditional Chinese medicine, has garnered academic attention as a multicomponent, multitarget approach to managing GC. The present editorial explores the potential of XJZ in the treatment of GC through a comprehensive analysis of network pharmacology and experimental validation. Network pharmacology was used to identify key molecular targets of XJZ, including interleukin 6, prostaglandin-endoperoxide synthase 2, and matrix metalloproteinase 9, and in vitro experiments were used to confirm the efficacy of XJZ in inhibiting cell proliferation, inducing apoptosis, and modulating gene expression associated with GC progression. This editorial highlights XJZ as a promising therapeutic strategy for GC and indicates a need for further clinical exploration and validation of its efficacy.

Abstract
Uterine artery pseudoaneurysm (UAP) is a rare but potentially life-threatening complication that can occur following hysteroscopic surgery for endometrial polyp resection. This article discusses the case study by Kakinuma et al, which highlights the successful diagnosis and treatment of UAP in a 48-year-old primiparous woman. Utilizing advanced imaging techniques such as ultrasound and computed tomography (CT), the medical team was able to promptly identify the UAP and subsequently perform a uterine artery embolization to treat the condition. The study underscores the critical need for rapid diagnosis and intervention to prevent severe outcomes and provides practical clinical recommendations for managing similar cases. This article aims to expand on the study’s findings, discuss the clinical implications, and suggest future research directions to optimize the management of UAP post-hysteroscopic surgery.

World J Gastrointest Oncol 2024; 16:4614-4624. [DOI: 10.4251/wjgo.v16.i12.4614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2024] [Revised: 08/13/2024] [Accepted: 09/05/2024] [Indexed: 11/12/2024] [Imported: 11/12/2024] Open
Abstract
BACKGROUND Rectal cancer has become one of the leading malignancies threatening people’s health. For locally advanced rectal cancer (LARC), the comprehensive strategy combining neoadjuvant chemoradiotherapy (NCRT), total mesorectal excision (TME), and adjuvant chemotherapy has emerged as a standard treatment regimen, leading to favorable local control and long-term survival. However, in recent years, an increasing attention has been paid on the exploration of organ preservation strategies, aiming to enhance quality of life while maintaining optimal oncological treatment outcomes. Local excision (LE), compared with low anterior resection (LAR) or abdominal-perineal resection (APR) was introduced dating back to 1970’s. LE has historically been linked to a heightened risk of recurrence compared to TME, potentially due to occult lymph node metastasis and intraluminal recurrence. Recent evidence has demonstrated that LE might be an alternative approach, instead of LAR or APR, in cases with favorable tumor regression after NCRT with potentially better quality of life. Therefore, a retrospective analysis of clinicopathological data from mid-low LARC patients who underwent LE after NCRT was conducted, aiming to evaluate the treatment's efficacy, safety, and oncologic prognosis.
AIM To explore the safety, efficacy, and long-term prognosis of LE in patients with mid-low rectal cancer who had a good response to NCRT.
METHODS Patients with LE between 2012 to 2021 were retrospectively collected from the rectal cancer database from Gastro-intestinal Ward III in Peking University Cancer Hospital. The clinicopathological features, postoperative complications, and long-term prognosis of these patients were analyzed. The Kaplan-Meier method was used to create cancer-specific survival curve, and the log-rank test was used to compare the differences regarding outcomes.
RESULTS A total of 33 patients were included in this study. The median interval between NCRT and surgery was 25.4 (range: 8.7-164.4) weeks. The median operation time was 57 (20.0-137.0) minutes. The initial clinical T staging (cT): 9 (27.3%) patients were cT2, 19 (57.6%) patients were cT3, and 5 (15.2%) patients were cT4; The initial N staging (cN): 8 patients (24.2%) were cN negative, 25 patients (75.8%) were cN positive; The initial M stage (cM): 2 patients (6.1%) had distant metastasis (ycM1), 31 (93.9%) patients had no distant metastasis (cM0). The pathological results: 18 (54.5%) patients were pathological T0 stage (ypT0), 6 (18.2%) patients were ypT1, 7 (21.2%) patients were ypT2, and 2 (6.1%) patients were ypT3. For 9 cT2 patients, 5 (5/9, 55.6%) had a postoperative pathological result of ypT0. For 19 cT3 patients, 11 (57.9%) patients were ypT0, and 2 (40%) were ypT0 in 5 cT4 patients. The most common complication was chronic perineal pain (71.4%, 5/7), followed by bleeding (43%, 3/7), stenosis (14.3%, 1/7), and fecal incontinence (14.3%, 1/7). The median follow-up time was 42.0 (4.0-93.5) months. For 31 patients with cM0, the 5-year disease-free survival (DFS) rate, 5-year local recurrence-free survival (LRFS) rate, and 5-year overall survival (OS) rate were 88.4%, 96.7%, and 92.9%, respectively. There were significant differences between the ycT groups concerning either DFS (P = 0.042) or OS (P = 0.002) in the Kaplan-Meier analysis. The LRFS curve of ycT ≤ T1 patients was better than that of ycT ≥ T2 patients, and the P value was very close to 0.05 (P = 0.070). The DFS curve of patients with ypT ≤ T1 was better than that of patients with ypT ≥ T2, but the P value was not statistically significant (P = 0.560). There was a significant difference between the ypT groups concerning OS (P = 0.014) in the Kaplan-Meier analysis. The LRFS curve of ypT ≤ T1 patients was better than that of ypT ≥ T2 patients, and the P value was very close to 0.05 (P = 0.070). Two patients with initial cM1 were alive at the last follow-up.
CONCLUSION LE for rectal cancer with significant tumor regression after NCRT can obtain better safety, efficiency, and oncological outcome. Minimally invasive or nonsurgical treatment with patient participation in decision-making can be performed for highly selected patients. Further investigation from multiple centers will bring better understanding of potential advantages regarding local resection.

Abstract
This manuscript used network pharmacology and experimental verification to analyze the anti-hepatocarcinoma mechanism of action of bezoars in traditional Chinese medicine (TCM), discovering that it can affect the immune cells within the tumor microenvironment and related pathways to produce inhibitory effects in liver cancer. In TCM, bezoars have a unique therapeutic advantage in the prevention and treatment of tumors. They play an anti-tumorigenic role by regulating the immune microenvironment through multi-component, multi-target and multi-pathway mechanisms. With the application of nanotechnology, bezoars and their compound preparations have been developed into anti-cancer drugs with unique therapeutic advantages, providing novel treatment options for tumor patients.

Abstract
BACKGROUND Colorectal cancer (CRC), the third most common cancer worldwide, has increasingly detrimental effects on human health. Radiotherapy resistance diminishes treatment efficacy. Studies suggest that spermine synthase (SMS) may serve as a potential target to enhance the radiosensitivity.
AIM To investigate the association between SMS and radiosensitivity in CRC cells, along with a detailed elucidation of the underlying mechanisms.
METHODS Western blot was adopted to assess SMS expression in normal colonic epithelial cells and CRC cell lines. HCT116 cells were transfected with control/SMS-specific shRNA or control/pcDNA3.1-SMS plasmids. Assessments included cell viability, colony formation, and apoptosis via MTT assays, colony formation assays, and flow cytometry. Radiosensitivity was studied in SMS-specific shRNA-transfected HCT116 cells post-4 Gy radiation, evaluating cell viability, colony formation, apoptosis, DNA damage (comet assays), autophagy (immunofluorescence), and mammalian target of rapamycin (mTOR) pathway protein expression (western blot).
RESULTS Significant up-regulation of SMS expression levels was observed in the CRC cell lines. Upon down-regulation of SMS expression, cellular viability and colony-forming ability were markedly suppressed, concomitant with a notable increase in apoptotic indices. Furthermore, attenuation of SMS expression significantly augmented the sensitivity of HCT116 cells to radiation therapy, evidenced by a pronounced elevation in levels of cellular DNA damage and autophagy. Importantly, down-regulation of SMS corresponded with a marked reduction in the expression levels of proteins associated with the mTOR signaling pathway.
CONCLUSION Knocking down SMS attenuates the mTOR signaling pathway, thereby promoting cellular autophagy and DNA damage to enhance the radiosensitivity of CRC cells.

Abstract
BACKGROUND Esophageal cancer (EC) often occurs in the elderly, with approximately 33% of patients aged ≥ 75 years at the time of diagnosis.
AIM To evaluate the prognostic factors for radiotherapy (RT) in elderly patients with unresectable EC.
METHODS We retrospectively analyzed the clinical characteristics, toxic reactions, and survival information of EC patients aged ≥ 75 years who underwent intensity-modulated RT at Lu’an Hospital of Anhui Medical University between January 2016 and September 2023. Kaplan-Meier analysis was used to draw the overall survival (OS) curves, and Cox regression analysis was employed to evaluate the influence of various clinical factors on the prognosis.
RESULTS A total of 139 patients were enrolled. The median follow-up time was 52.0 months. The median OS was 20.0 months. The 1-year, 2-year, 3-year, and 5-year OS rates were 69.8%, 38.7%, 28.2%, and 17.5%, respectively. Univariate analysis showed that age, radiation dose, and chemotherapy had no significant impact on prognosis. Multivariate analysis indicated that clinical stage [III-IVa vs I-II, hazard ratio (HR) = 2.421, 95% confidence interval (CI): 1.242-4.718, P = 0.009; IVb vs I-II, HR = 4.222, 95%CI: 1.888-9.438, P < 0.001), Charlson comorbidity index (CCI) (0 vs ≥ 1, HR = 1.539, 95%CI: 1.015-2.332, P = 0.042), and nutritional risk screening 2002 (NRS2002) (< 3 vs ≥ 3, HR = 2.491, 95%CI: 1.601-3.875, P < 0.001) were independent prognostic factors for OS.
CONCLUSION Our results suggest that CCI and NRS2002 were independent prognostic factors of OS for unresectable elderly EC patients undergoing RT. For elderly patients with EC, full attention should be given to biological age-related indicators, such as comorbidities and nutrition, when formulating treatment protocols. These factors should be considered in future clinical practice.

Abstract
BACKGROUND Gastrointestinal stromal tumors (GIST) are prevalent neoplasm originating from the gastrointestinal mesenchyme. Approximately 50% of GIST patients experience tumor recurrence within 5 years. Thus, there is a pressing need to accurately evaluate risk stratification preoperatively.
AIM To assess the application of a deep learning model (DLM) combined with computed tomography features for predicting risk stratification of GISTs.
METHODS Preoperative contrast-enhanced computed tomography (CECT) images of 551 GIST patients were retrospectively analyzed. All image features were independently analyzed by two radiologists. Quantitative parameters were statistically analyzed to identify significant predictors of high-risk malignancy. Patients were randomly assigned to the training (n = 386) and validation cohorts (n = 165). A DLM and a combined DLM were established for predicting the GIST risk stratification using convolutional neural network and subsequently evaluated in the validation cohort.
RESULTS Among the analyzed CECT image features, tumor size, ulceration, and enlarged feeding vessels were identified as significant risk predictors (P < 0.05). In DLM, the overall area under the receiver operating characteristic curve (AUROC) was 0.88, with the accuracy (ACC) and AUROCs for each stratification being 87% and 0.96 for low-risk, 79% and 0.74 for intermediate-risk, and 84% and 0.90 for high-risk, respectively. The overall ACC and AUROC were 84% and 0.94 in the combined model. The ACC and AUROCs for each risk stratification were 92% and 0.97 for low-risk, 87% and 0.83 for intermediate-risk, and 90% and 0.96 for high-risk, respectively. Differences in AUROCs for each risk stratification between the two models were significant (P < 0.05).
CONCLUSION A combined DLM with satisfactory performance for preoperatively predicting GIST stratifications was developed using routine computed tomography data, demonstrating superiority compared to DLM.
