Triple-negative breast cancer survival prediction using artificial intelligence through integrated analysis of tertiary lymphoid structures and tumor budding.

BACKGROUND: Triple-negative breast cancer (TNBC) is a highly heterogeneous and clinically aggressive disease. Accumulating evidence indicates that tertiary lymphoid structures (TLSs) and tumor budding (TB) are significantly correlated with the outcomes of patients who have TNBC, but no integrated TLS-TB profile has been established to predict their survival. The objective of this study was to investigate the relationship between the TLS/TB ratio and clinical outcomes of patients with TNBC using artificial intelligence (AI)-based analysis. METHODS: The infiltration levels of TLSs and TB were evaluated using hematoxylin and eosin staining, immunohistochemistry staining, and AI-based analysis. Various cellular subtypes within TLS were determined by multiplex immunofluorescence. Subsequently, the authors established a nomogram model, conducted calibration curve analyses, and performed decision curve analyses using R software. RESULTS: In both the training and validation cohorts, the antitumor/protumor model established by the authors demonstrated a positive correlation between the TLS/TB index and the overall survival (OS) and relapse-free survival (RFS) of patients with TNBC. Notably, patients who had a high percentage of CD8-positive T cells, CD45RO-positive T cells, or CD20-positive B cells within the TLSs experienced improved OS and RFS. Furthermore, the authors developed a comprehensive TLS-TB profile nomogram based on the TLS/TB index. This novel model outperformed the classical tumor-lymph node-metastasis staging system in predicting the OS and RFS of patients with TNBC. CONCLUSIONS: A novel strategy for predicting the prognosis of patients with TNBC was established through integrated AI-based analysis and a machine-learning workflow. The TLS/TB index was identified as an independent prognostic factor for TNBC. This nomogram-based TLS-TB profile would help improve the accuracy of predicting the prognosis of patients who have TNBC.

Transhepatectomy combined with arterial chemoembolization and transcatheter arterial chemoembolization in the treatment of hepatocellular carcinoma: a clinical prognostic analysis.

BACKGROUND: The prognosis of patients undergoing hepatectomy combined with transarterial chemoembolization (TACE) and TACE alone was examined in order to better understand the role of hepatectomy in the treatment of hepatocellular carcinoma (HCC). In this work, we also created a model and investigated the variables influencing overall survival (OS) in HCC patients. METHODS: Retrospective analysis of 1083 patients who received TACE alone as the control group and 188 patients who received TACE after surgery in a total of 1271 HCC patients treated with LR + TACE or TACE at three third-class hospitals in China. It was done using the Propensity Score Matching (PSM) technique. The differences in OS between the two groups were compared, and OS-influencing factors were looked at. The main endpoint is overall survival. In this study, the COX regression model was used to establish the nomogram. RESULTS: The median OS of the LR + TACE group was not attained after PSM. The median OS for the TACE group was 28.8 months (95% CI: 18.9-38.7). The median OS of the LR + TACE group was higher than that of the TACE group alone, indicating a significant difference between the two groups (χ2 = 16.75, P < 0.001). While it was not achieved in the LR + TACE group, the median OS for patients with lymph node metastases in the TACE group alone was 18.8 months. The two groups differed significantly from one another (χ2 = 4.105, P = 0.043). In patients with distant metastases, the median OS of the LR + TACE treatment group was not achieved, and the median OS of the TACE group alone was 12.0 months. The difference between the two groups was sizable (χ2 = 5.266, P = 0.022). The median OS for patients with PVTT following PSM was 30.1 months in the LR + TACE treatment group and 18.7 months in the TACE alone group, respectively. The two groups differed significantly from one another (χ2 = 5.178, P = 0.023); There was no discernible difference between the two groups in terms of median overall survival (OS), which was 30.1 months for patients with lymph node metastasis and 19.2 months for those without (P > 0.05); Regarding the median OS for patients with distant metastases, which was not achieved and 8.5 months, respectively, there was a significant difference between the two groups (χ2 = 5.759, P = 0.016). We created a new nomogram to predict 1-, 2-, and 3-year survival rates based on multiple independent predictors in COX multivariate analysis. The cohort's C-index is 0.705. The area under the curve (AUC value) for predicting 1-, 2-, and 3-year survival rates were shown by the subject operating characteristic (ROC) curve linked to the nomogram to be 0.730, 0.728, and 0.691, respectively. CONCLUSIONS: LR + TACE can increase OS, delay tumor recurrence, and improve prognosis in HCC patients when compared to TACE alone. Additionally, the nomogram we created does a good job of forecasting the 1-year survival rate of hepatocellular carcinoma.

Construction and validation of a nomogram for HBV-related hepatocellular carcinoma: A large, multicenter study.

INTRODUCTION AND OBJECTIVES: We initiated this multicenter study to integrate important risk factors to create a nomogram for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) for clinician decision-making. PATIENTS AND METHODS: Between April 2011 and March 2022, 2281 HCC patients with an HBV-related diagnosis were included. All patients were randomly divided into two groups in a ratio of 7:3 (training cohort, n = 1597; validation cohort, n = 684). The nomogram was built in the training cohort via Cox regression model and validated in the validation cohort. RESULTS: Multivariate Cox analyses revealed that the portal vein tumor thrombus, Child-Pugh class, tumor diameter, alanine aminotransferase level, tumor number, extrahepatic metastases, and therapy were independent predictive variables impacting overall survival. We constructed a new nomogram to predict 1-, 2-, and 3-year survival rates based on these factors. The nomogram-related receiver operating characteristics (ROC) curves indicated that the area under the curve (AUC) values were 0.809, 0.806, and 0.764 in predicting 1-, 2-, and 3-year survival rates, respectively. Furthermore, the calibration curves revealed good agreement between real measurements and nomogram predictions. The decision curve analyses (DCA) curves demonstrated excellent therapeutic application potential. In addition, stratified by risk scores, low-risk groups had longer median OS than medium-high-risk groups (p < 0.001). CONCLUSIONS: The nomogram we constructed showed good performance in predicting the 1-year survival rate for HBV- related HCC.

Discovery of a novel megakaryopoiesis enhancer, ingenol, promoting thrombopoiesis through PI3K-Akt signaling independent of thrombopoietin.

Thrombocytopenia, a most common complication of radiotherapy and chemotherapy, is an important cause of morbidity and mortality in cancer patients. However, there are still no approved agents for the treatment of radiation- and chemotherapy-induced thrombocytopenia (RIT and CIT, respectively). In this study, a drug screening model for predicting compounds with activity in promoting megakaryocyte (MK) differentiation and platelet production was established based on machine learning (ML), and a natural product ingenol was predicted as a potential active compound. Then, in vitro experiments showed that ingenol significantly promoted MK differentiation in K562 and HEL cells. Furthermore, a RIT mice model and c-MPL knock-out (c-MPL-/-) mice constructed by CRISPR/Cas9 technology were used to assess the therapeutic action of ingenol on thrombocytopenia. The results showed that ingenol accelerated megakaryopoiesis and thrombopoiesis both in RIT mice and c-MPL-/- mice. Next, RNA-sequencing (RNA-seq) was carried out to analyze the gene expression profile induced by ingenol during MK differentiation. Finally, through experimental verifications, we demonstrated that the activation of PI3K/Akt signaling pathway was involved in ingenol-induced MK differentiation. Blocking PI3K/Akt signaling pathway abolished the promotion of ingenol on MK differentiation. Nevertheless, inhibition of TPO/c-MPL signaling pathway could not suppress ingenol-induced MK differentiation. In conclusion, our study builds a drug screening model to discover active compounds against thrombocytopenia, reveals the critical roles of ingenol in promoting MK differentiation and platelet production, and provides a promising avenue for the treatment of RIT.

Clinical efficacy and safety of external radiotherapy combined with sorafenib in the treatment of hepatocellular carcinoma: a systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: Both external radiotherapy and sorafenib are promising treatments for hepatocellular carcinoma (HCC). Nevertheless, the combined treatment of external radiotherapy and sorafenib has not been widely applied clinically due to potentially adverse effects. This meta-analysis aimed to evaluate the clinical efficacy and safety of external radiotherapy combined with sorafenib in the treatment of HCC. METHODS: Pubmed, MEDLINE, EMBASE, Cochrane Library, and Web of Science databases were searched. The primary and secondary observation endpoints were the end of survival and incidence of adverse events, respectively. 11 studies involving 664 patients were included in this meta-analysis. RESULTS: The results demonstrated that median overall survival (mOS) and median progression-free survival (mPFS) of the external radiotherapy combined with sorafenib (RS) group were 19.45 months and 8.20 months. The one- and two-year survival rates were 0.65 (95%CI: 0.55-0.76) and 0.40 (95%CI: 0.24-0.56). The incidence of adverse events was 0.34 (95%CI: 0.25-0.44). CONCLUSIONS: The findings demonstrated that the survival of the RS group was significantly improved and few severe adverse events were observed. Hence, it can be concluded that external radiotherapy combined with sorafenib is a safe, effective, and promising therapeutic option for HCC.

Apatinib Combined With Radiotherapy Enhances Antitumor Effects in an In Vivo Nasopharyngeal Carcinoma Model.

Vascular endothelial growth factor (VEGF) and its receptor (VEGFR) are highly expressed in nasopharyngeal carcinoma; therefore, blocking the binding of VEGF and VEGFR may be a potential way to treat nasopharyngeal carcinoma. Apatinib inhibits tumor angiogenesis. Previous studies have suggested that treatment with apatinib has an antitumor effect on nasopharyngeal carcinoma. This study will investigate the effect of apatinib combined with radiotherapy. In this study, nude mice injected with CNE-2 nasopharyngeal carcinoma cells were randomly divided into 6 groups. Therapeutic effects were assessed by evaluating tumor inhibition rate, phosphorylation of VEGFR-2, CD31, partial oxygen pressure, and tumor metabolism. We found that the tumor inhibition of mice in the treated groups was better compared to that of the control group. In mice treated with apatinib alone, angiogenesis was prevented, and the tumor tissue partial oxygen pressure was reduced, thereby achieving an antitumor effect. Moreover, the tumor inhibitory effect of combined treatment was stronger than treatment with either apatinib or radiotherapy alone. Compared with monotherapy treatment, combined treatment better resisted angiogenesis. Apatinib combined with radiotherapy to treat nasopharyngeal carcinoma has synergistic effects, which may be related to enhanced antiangiogenesis.

Precise pathologic diagnosis and individualized treatment improve the outcomes of invasive micropapillary carcinoma of the breast: a 12-year prospective clinical study.

Invasive micropapillary carcinoma of the breast is a histologic subtype of breast cancer and associated with high incidence of lymphovascular invasion, lymph node metastasis and poor prognosis. The aim of this prospective study was to investigate the impact of precise pathologic diagnosis and individualized treatment on the outcomes of invasive micropapillary carcinoma of the breast. The study group included 2299 women with invasive micropapillary carcinoma diagnosed at Tianjin Medical University Cancer Institute and Hospital between January 2004 and December 2015. In the study group, specimens were examined with the method of whole-specimen orientation and serial sectioning, and patients received precise pathological diagnosis and individualized treatment. The control group of invasive micropapillary carcinoma consisted of 163 cases, identified through a retrospectively review of 9056 invasive carcinomas diagnosed at our institution between January 1989 and December 2003 using the standard pathology-evaluation method (i.e., not using the whole-specimen orientation and serial-sectioning method). The clinicopathological features, treatments and outcomes were compared between the two groups. The incidence of invasive micropapillary carcinoma in the study group was 6% (2299/39,714 cases), significantly higher than that of the control group (2%; 163/9056 cases). The 5-year disease-free survival in the study group was significantly higher than that in the control group (83.8 vs.45.4%; p < 0.05). The 5-year overall survival was significantly increased from 57.4% in the control group to 90.9% in the study group (p < 0.05). In the multivariate analysis, lymphovascular invasion, estrogen receptor status and lymph node metastasis were independent prognostic factors. Although invasive micropapillary carcinoma of the breast is associated with poor prognosis, precise pathologic diagnosis and individualized treatment improved the disease-free survival and overall survival of invasive micropapillary carcinoma patients. Precise pathological diagnosis is the premises for individualized treatments and for improving the outcomes of patients with invasive micropapillary carcinoma of the breast.

Enhanced antitumor and anti-angiogenic effects of metronomic Vinorelbine combined with Endostar on Lewis lung carcinoma.

BACKGROUND: Conventional chemotherapy is commonly used to treat non-small cell lung cancer (NSCLC) however it increases therapeutic resistance. In contrast, metronomic chemotherapy (MET) is based on frequent drug administration at lower doses, resulting in inhibition of neovascularization and induction of tumor dormancy. This study aims to evaluate the inhibitory effects, adverse events, and potential mechanisms of MET Vinorelbine (NVB) combined with an angiogenesis inhibitor (Endostar). METHODS: Circulating endothelial progenitor cells (CEPs), apoptosis rate, expression of CD31, vascular endothelial growth factor (VEGF), hypoxia inducible factor-1 (HIF-1α) were determined using flow cytometry, western blot analysis, immunofluorescence staining and Enzyme-linked immunosorbent assay (ELISA) analysis. And some animals were also observed using micro fluorine-18-deoxyglucose PET/computed tomography (18F-FDG PET/CT) to identify changes by comparing SUVmax values. In addition, white blood cell (WBC) counts and H&E-stained sections of liver, lungs, kidney, and heart were performed in order to monitor toxicity assessments. RESULTS: We found that treatment with MET NVB + Endo was most effective in inhibiting tumor growth, decreasing expression of CD31, VEGF, HIF-1α, and CEPs, and reducing side effects, inducing apoptosis, such as expression of Bcl-2, Bax and caspase-3. Administration with a maximum tolerated dose of NVB combined with Endostar (MTD NVB + Endo) demonstrated similar anti-tumor effects, including changes in glucose metabolism with micro fluorine-18-deoxyglucose PET/computed tomography (18F-FDG PET/CT) imaging, however angiogenesis was not inhibited. Compared with either agent alone, the combination of drugs resulted in better anti-tumor effects. CONCLUSION: These results indicated that MET NVB combined with Endo significantly enhanced anti-tumor and anti-angiogenic responses without overt toxicity in a xenograft model of human lung cancer.

MicroRNA-183 promotes migration and invasion of CD133(+)/CD326(+) lung adenocarcinoma initiating cells via PTPN4 inhibition.

Non-small cell lung cancer (NSCLC) is the most common cancer worldwide and is a leading cause of lung cancer mortality due to early stage metastases. Cancer stem-like cells (CSLCs) or tumor-initiating cells (TICs) are rare subpopulation cells that are responsible for maintaining tumor growth and invasion leading to recurrence and metastasis. Previous studies revealed that miR-183 can mediate the invasiveness and growth of NSCLC. However, the exact role of miR-183 in regulating the biological behavior of CSLCs in NSCLC remains unclear. In the present study, we explored the regulation of protein tyrosine phosphatase non-receptor type 4 (PTPN4) by miR-183 in vitro using luciferase reporter assays, and we further analyzed the effects of miR-183 on the invasiveness of CSLCs in vitro and in vivo using transwell and bioluminescence assays. Following our finding that miR-183 binds to PTPN4 messenger RNA (mRNA) to prevent its translation through the 3'-untranslated region (UTR), we found that overexpression of miR-183 in CSLCs decreased PTPN4 protein levels while inhibition of miR-183 increased PTPN4 protein levels. The suppression of PTPN4 levels in CSLCs by miR-183 paralleled with a significant promotion in their motility in vitro and in vivo, while anti-sense miR-183 increased PTPN4 levels in CSLCs, which paralleled with a significant decrease in their invasiveness. Furthermore, correlation analysis between miR-183 and PTPN4 in clinical samples demonstrated a statistically significant inverse correlation between PTPN4 mRNA levels and miR-183. In brief, our data indicate that miR-183 plays a pro-invasive role by inverse regulation of PTPN4, and this axis may be a new therapeutic target for suppressing the metastatic capability of CSLCs in NSCLC.

Clinicopathologic characteristics and prognosis of glycogen-rich clear cell carcinoma of the breast.

Glycogen-rich clear cell carcinoma (GRCC) of the breast is a rare type of breast carcinoma. Knowledge about the characteristics of this type is fragmentary, and the prognosis is on debate. In this study, we aimed to summarize the clinical, pathologic, and biologic characteristics of GRCC of the breast and analyze the survival. We reviewed the cases of breast cancer in our hospital between January 1999 and December 2009 and identified 28 patients as GRCC of the breast. The routine hematoxylin-eosin staining, periodic acid-Schiff (PAS) staining, and diastase PAS staining were performed on the tumor tissues. The expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2), Ki67 and P53 were evaluated by immunohistochemistry. Tumors with a HER-2 score of 2+ were confirmed by fluorescent in situ hybridization test. Each GRCC case, who had complete follow-up data, was compared with four cases of usual invasive ductal carcinomas as controls in the same database and matched with age, year of diagnosis, tumor size, nodal status, and immunophenotype. The chi-squared test and the Fisher's exact test were used to compare the characteristics of GRCC cases and controls. The univariate analysis was used to study the prognosis, and Kaplan-Meier method was used to compare the survival of two groups. The clinicopathologic and imaging features were analyzed in the GRCC cases. Tumor sizes ranged from 0.8 to 7.5 cm (mean, 3.2 cm). Thirteen cases (46.4%) had positive lymph nodes. The positivity of ER and PR was 61.5% (16 of 26). HER-2 was positive for three cases (12%). The positivity of Ki67 and P53 were 87.5% and 45.8%, respectively. Twenty-four cases were followed up from 19 to 158 months. The prognosis of GRCC of the breast was significantly related with the number of positive lymph nodes (p < 0.001), and patients with more than 10 positive lymph nodes were at high risk of recurrence or metastasis. There was no significant difference in overall survival (p = 0.547), and disease-free survival (p = 0.900) between GRCC of the breast and the usual invasive ductal carcinomas. GRCC of the breast may not have a worse survival.

Prognostic value of circulating tumor cells combined with neutrophil-lymphocyte ratio in patients with hepatocellular carcinoma.

BACKGROUND: Circulating tumor cell (CTC) count and neutrophil-to-lymphocyte ratio (NLR) are both closely associated with the prognosis of hepatocellular carcinoma (HCC). AIM: To investigate the prognostic value of combining these two indicators in HCC. METHODS: Clinical data were collected from patients with advanced HCC who received immune therapy combined with targeted therapy at the Department of Oncology, the Affiliated Hospital of Southwest Medical University, Sichuan, China, from 2021 to 2023. The optimal cutoff values for CTC programmed death-ligand 1 (PD-L1) (+) > 1 or CTC PD-L1 (+) ≤ 1 and NLR > 3.89 or NLR ≤ 3.89 were evaluated using X-Tile software. Patients were categorized into three groups based on CTC PD-L1 (+) counts and NLR: CTC-NLR (0), CTC-NLR (1), and CTC-NLR (2). The relationship between CTC-NLR and clinical variables as well as survival rates was assessed. RESULTS: Patients with high CTC PD-L1 (+) expression or NLR at baseline had shorter median progression-free survival (mPFS) and median overall survival (mOS) than those with low levels of CTC PD-L1 (+) or NLR (P < 0.001). Meanwhile, patients in the CTC-NLR (2) group showed a significant decrease in mPFS and mOS. Cox regression analysis revealed that alpha-fetoprotein (AFP), CTC PD-L1 (+), and CTC-NLR were independent predictors of OS. The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months (0.821) and 18 months (0.821) was superior to that of AFP and CTC PD-L1 (+). CONCLUSION: HCC patients with high CTC PD-L1 (+) or NLR expression tend to exhibit poor prognosis, and a high baseline CTC-NLR score may indicate low survival. CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy.

Lasso-Cox interpretable model of AFP-negative hepatocellular carcinoma.

BACKGROUND: In AFP-negative hepatocellular carcinoma patients, markers for predicting tumor progression or prognosis are limited. Therefore, our objective is to establish an optimal predicet model for this subset of patients, utilizing interpretable methods to enhance the accuracy of HCC prognosis prediction. METHODS: We recruited a total of 508 AFP-negative HCC patients in this study, modeling with randomly divided training set and validated with validation set. At the same time, 86 patients treated in different time periods were used as internal validation. After comparing the cox model with the random forest model based on Lasso regression, we have chosen the former to build our model. This model has been interpreted with SHAP values and validated using ROC, DCA. Additionally, we have reconfirmed the model's effectiveness by employing an internal validation set of independent periods. Subsequently, we have established a risk stratification system. RESULTS: The AUC values of the Lasso-Cox model at 1, 2, and 3 years were 0.807, 0.846, and 0.803, and the AUC values of the Lasso-RSF model at 1, 2, and 3 years were 0.783, 0.829, and 0.776. Lasso-Cox model was finally used to predict the prognosis of AFP-negative HCC patients in this study. And BCLC stage, gamma-glutamyl transferase (GGT), diameter of tumor, lung metastases (LM), albumin (ALB), alkaline phosphatase (ALP), and the number of tumors were included in the model. The validation set and the separate internal validation set both indicate that the model is stable and accurate. Using risk factors to establish risk stratification, we observed that the survival time of the low-risk group, the middle-risk group, and the high-risk group decreased gradually, with significant differences among the three groups. CONCLUSION: The Lasso-Cox model based on AFP-negative HCC showed good predictive performance for liver cancer. SHAP explained the model for further clinical application.

[Differences and clinical significance of receptor expression between primary and locally recurrent breast tumor tissues].

OBJECTIVE: To compare the difference of receptor expression between primary and locally recurrent breast tumor tissues, and analyze their impact on survival of the patients. METHODS: The expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) of primary and locally recurrent breast tumor tissues of 70 breast cancer patients were analyzed by immunohistochemistry or fluorescence in situ hybridization. The impact of the differences on overall survival (OS) and post-recurrence survival (PRS) of the patients was analyzed. RESULTS: The effective discrepancy rates between primary and locally recurrent breast cancer tissues were 26.1% (18/69) for ER, 50.0% (34/68) for PR, and 10.3%(4/39) for HER-2 expressions. In the 60 cases who had complete follow-up data, 23 patients (38.3%) died and the median overall survival was 107 months (11-288 months). The 3-, 5- and 10-year overall survival rates were 84.3%, 71.6% and 45.7%, respectively. Kaplan-Meier survival analysis showed that the changes of ER expression had significant impact on the OS (P = 0.001) and PRS (P < 0.001), but PR had no significant effect on OS (P = 0.416) and PRS (P = 0.056). However, the OS and PRS for patients with PR⁺ locally recurrent tumors were better than that of PR⁻ patients regardless of the primary tumor PR status. The expression of HER-2 had no significant effect on the OS (P = 0.840) and PRS (P = 0.544) of the patients. CONCLUSIONS: An expression discrepancy of ER, PR and HER-2 exists between primary and locally recurrent breast cancer tissues, it significantly affects the survival of the patients. Re-evaluation of the expressions of ER, PR and HER-2 receptor in locally recurrent breast tumor tissue is beneficial for their therapy and prognosis.

Study on the role and pharmacology of cuproptosis in gastric cancer.

Objective: Gastric cancer has a poor prognosis and high mortality. Cuproptosis, a novel programmed cell death, is rarely studied in gastric cancer. Studying the mechanism of cuproptosis in gastric cancer is conducive to the development of new drugs, improving the prognosis of patients and reducing the burden of disease. Methods: The TCGA database was used to obtain transcriptome data from gastric cancer tissues and adjacent tissues. GSE66229 was used for external verification. Overlapping genes were obtained by crossing the genes obtained by differential analysis with those related to copper death. Eight characteristic genes were obtained by three dimensionality reduction methods: lasso, SVM, and random forest. ROC and nomogram were used to estimate the diagnostic efficacy of characteristic genes. The CIBERSORT method was used to assess immune infiltration. ConsensusClusterPlus was used for subtype classification. Discovery Studio software conducts molecular docking between drugs and target proteins. Results: We have established the early diagnosis model of eight characteristic genes (ENTPD3, PDZD4, CNN1, GTPBP4, FPGS, UTP25, CENPW, and FAM111A) for gastric cancer. The results are validated by internal and external data, and the predictive power is good. The subtype classification and immune type analysis of gastric cancer samples were performed based on the consensus clustering method. We identified C2 as an immune subtype and C1 as a non-immune subtype. Small molecule drug targeting based on genes associated with cuproptosis predicts potential therapeutics for gastric cancer. Molecular docking revealed multiple forces between Dasatinib and CNN1. Conclusion: The candidate drug Dasatinib may be effective in treating gastric cancer by affecting the expression of the cuproptosis signature gene.

Effectiveness of c-TACE Combined With Sorafenib Versus c-TACE Monotherapy in Advanced Hepatocellular Carcinoma: A Retrospective Study.

Background: Hepatocellular carcinoma (HCC) has insidious onset. Most HCC patients are in advanced stage at the time of initial diagnosis, and the treatment response is poor. The purpose of this study was to compare the clinical effectiveness of conventional transcatheter arterial chemoembolization (c-TACE) combined with sorafenib versus c-TACE monotherapy in the treatment of advanced HCC. Methods: A retrospective analysis was performed on patients with advanced HCC (stage C based on the Barcelona Clinic Liver Cancer staging system) admitted to the Affiliated Hospital of Southwest Medical University from December 9, 2013, to February 25, 2021. After screening for inclusion and exclusion criteria, 120 patients were finally included, including 60 patients in the c-TACE group and 60 patients in c-TACE + sorafenib group. There were no statistically significant differences in general data between the 2 groups before treatment. Overall survival (OS) and progression-free survival (PFS) were compared between the 2 groups, and prognostic factors were assessed by Cox proportional risk model. Results: The study found that median PFS was 7.37 months in the c-TACE + sorafenib group and 5.97 months in c-TACE group, a statistically significant difference (χ2 = 5.239, P = .022 < .05). The median OS was 22.9 months in the combination group and 12.1 months in c-TACE monotherapy group, also a statistically significant difference (χ2 = 5.848, P = .016 < .05). The Cox proportional risk model found that c-TACE number and presence of ascites were common risk factors among patients in both groups (P < .05). Conclusion: c-TACE + sorafenib was superior to c-TACE alone in the treatment of advanced HCC and yielded significant improvements in PFS and OS in our study. The number of c-TACE and presence of ascites were common risk factors affecting the survival of patients in the 2 groups.

Comparison of the efficacy and safety of selective internal radiotherapy and sorafenib alone or combined for hepatocellular carcinoma: a systematic review and Bayesian network meta-analysis.

BACKGROUND: Selective internal radiation therapy (SIRT) is a developing technique and its efficacy and modality of application in hepatocellular carcinoma (HCC) are still controversial. This network meta-analysis aims to determine whether the efficacy and safety of SIRT alone and in combination are superior to that of sorafenib. METHODS: Four databases (PubMed, Embase, Cochrane Library, and Web of Science) were searched before August 2022. Cochrane Randomized Trial Risk of Bias Assessment Tool and the Newcastle-Ottawa scale were used to assess the quality. The outcomes of interest included overall survival (OS), progression-free survival (PFS), and adverse events (AEs). RESULTS: A total of 9 eligible trials involving 1954 patients were included, and SIRT ranked first among the three treatment modalities in terms of both OS (probability, 52.3%) and PFS (probability, 68.6%). The combination of SIRT and sorafenib did not improve OS or PFS in patients with HCC. Although the combination of SIRT and sorafenib did not raise the risk of grade 3 or higher AEs, it may have introduced more AEs than either alone. CONCLUSIONS: SIRT alone was found to be superior to sorafenib and the combination of the two in improving OS or PFS in patients with non-surgical HCC, especially in patients with combined portal vein tumor thrombus. The AEs induced by SIRT were different from those of sorafenib, but the overall toxicity was manageable, the combination of the two may cause an increase in the types of AEs that occur.

The ALDH2, IGSF9, and PRDM16 Proteins as Predictive Biomarkers for Prognosis in Breast Cancer.

INTRODUCTION: ALDH2, IGSF9, and PRDM16 play crucial roles in regulating diverse cellular pathophysiologic functions. The current study was to evaluate the effect of the 3 proteins on clinicopathologic features and prognosis of patients with breast cancer. MATERIALS AND METHODS: The formalin-fixed and paraffin-embedded tissue specimens were collected from breast cancer patients by immunohistochemistry (IHC) were analyzed. RESULTS: Of the 216 patients enrolled, ALDH2 high expression was significantly correlated with the age (p = .040), larger tumor size (p = .001), LVI (p < .001), LNM (p < .001), advanced TNM staging (p < .001), PR (p = .027), HER2 status (p = .002), and molecular subtype (p = .003). IGSF9 low expression was significantly correlated with the LV1 (p = .024), LNM (p = .024), advanced TNM staging (p = .001). The low expression of PRDM16 was significantly correlated with age (p = .023), and LNM (p = .014). The A+I-P- expression (13.4%) were markedly correlated with lymphatic vessel invasion (LVI) (p < .001), lymph node metastasis (LNM) (p < .001), advanced TNM staging (p < .001). Furthermore, patients with A+I-P- expression had significantly advanced-stage breast cancer [stage III (72.4%) vs. (23.0%)]. Univariate and multivariate analysis identified variables (ie, larger tumor size, lymph node involvement, and A+I-P- expression) as independent prognostic factors for survival. CONCLUSION: Our results reveal ALDH2 high expression, IGSF9 and PRDM16 low expression, A+I-P- expression was associated with advanced clinicopathological characteristics, and shorter OS and DFS in breast cancer patients. The 3 proteins may be potential prognosis markers and therapeutic targets for breast cancer patients.

Different types of fruit intake and colorectal cancer risk: A meta-analysis of observational studies.

BACKGROUND: Multiple studies investigating the relationship between intake of different types of fruit and colorectal cancer (CRC) risk have yielded inconsistent results. AIM: To perform a meta-analysis of existing studies to assess the association between the intake of different kinds of fruit and the incidence of CRC. METHODS: We searched online literature databases including PubMed, Embase, WOS, and Cochrane Library for relevant articles available up to August 2022. With data extracted from observational studies, odds ratios (ORs) with 95% confidence intervals (CIs) were assessed using random-effects models. A funnel plot and Egger's test were used to determine publication bias. Furthermore, subgroup analysis and dose-response analysis were performed. All analyses were conducted using R (version 4.1.3). RESULTS: Twenty-four eligible studies involving 1068158 participants were included in this review. The meta-analysis showed that compared to a low intake, a higher intake of citrus, apples, watermelon, and kiwi reduced the risk of CRC by 9% [OR (95%CI) = 0.91 (0.85-0.97)], 25% [OR (95%CI) = 0.75 (0.66-0.85)], 26% [OR (95%CI) = 0.74 (0.58-0.94)], 13% [OR (95%CI) = 0.87 (0.78-0.96)], respectively. No significant association was observed between the intake of other types of fruit and the risk of CRC. In the dose-response analysis, a nonlinear association was found [R (95%CI) = -0.0031 (-0.0047 to -0.0014)] between citrus intake and CRC risk (P < 0.001), with the risk minimized around 120 g/d (OR = 0.85), while no significant dose-response correlation was observed after continued increase in intake. CONCLUSION: We found that a higher intake of citrus, apples, watermelon, and kiwi was negatively associated with the risk of CRC, while the intake of other types of fruits were not significantly associated with CRC. Citrus intake showed a non-linear dose-response relationship with the risk of CRC. This meta-analysis provides further evidence that a higher intake of specific types of fruit is effective in preventing the occurrence of CRC.

A polyoxometalate-based heterojunction nanozyme with peroxidase-mimic catalytic activity for sensitive biomolecule detection.

Nanozymes are a class of nanomaterials that can specifically mimic the structures and catalytic activities as well as overcome limitations of natural enzymes and have hence been considered as a competitive alternative to natural enzymes. At present, plenty of nanozymes, especially those with peroxidase (POD)-like catalytic activity, have been extensively explored for biosensing. In this work, we proposed polyoxometalate-based heterojunction GdP5W30O110@WS2 nanoclusters (NCs) to exert intrinsic POD-like catalytic activity even under harsh catalytic conditions. Detailedly, GdP5W30O110@WS2 NCs possessing conducive POD-like catalytic activity can oxidize chromogenic substrates into colored substances in the presence of H2O2. On the strength of the POD-like catalytic activity of GdP5W30O110@WS2 NCs, a reliable analytical platform is then constructed after the optimization of catalytic conditions for the detection of H2O2, glutathione (GSH) and glucose via a simple TMB colorimetric strategy. This work advances the utilization of versatile polyoxometalate-based nanomaterials for biosensing, dramatically broadening the potential applications of other nanozyme-based biosensors.

Efficacy and safety of enhanced recovery after surgery protocol on minimally invasive bariatric surgery: a meta-analysis.

BACKGROUND: Enhanced recovery after surgery (ERAS), a multidisciplinary and multimodal perioperative care protocol, has been widely used in several surgical fields. However, the effect of this care protocol on patients receiving minimally invasive bariatric surgery remains unclear. This meta-analysis compared the clinical outcomes of the ERAS protocol and standard care (SC) in patients who underwent minimally invasive bariatric surgery. MATERIAL AND METHODS: PubMed, Web of Science, Cochrane Library, and Embase databases were systematically searched to identify literature reporting the effects of the ERAS protocol on clinical outcomes in patients undergoing minimally invasive bariatric surgery. All the articles published until 01 October 2022, were searched, followed by data extraction of the included literature and independent quality assessment. Then, pooled mean difference (MD) and odds ratio with a 95% CI were calculated by either a random-effects or fixed-effects model. RESULTS: Overall, 21 studies involving 10 764 patients were included in the final analysis. With the ERAS protocol, the length of hospitalization (MD: -1.02, 95% CI: -1.41 to -0.64, P <0.00001), hospitalization costs (MD: -678.50, 95% CI: -1196.39 to -160.60, P =0.01), and the incidence of 30-day readmission (odds ratio =0.78, 95% CI: 0.63-0.97, P =0.02) were significantly reduced. The incidences of overall complications, major complications (Clavien-Dindo grade ≥3), postoperative nausea and vomiting, intra-abdominal bleeding, anastomotic leak, incisional infection, reoperation, and mortality did not differ significantly between the ERAS and SC groups. CONCLUSIONS: The current meta-analysis indicated that the ERAS protocol could be safely and feasibly implemented in the perioperative management of patients receiving minimally invasive bariatric surgery. Compared with SC, this protocol leads to significantly shorter hospitalization lengths, lower 30-day readmission rate, and hospitalization costs. However, no differences were observed in postoperative complications and mortality.
