BACKGROUND:The Ovarian-Adnexal Reporting and Data System (O-RADS) is essential for standardizing the risk stratification of ovarian lesions detected on ultrasound. However, manual assignment of O-RADS scores is time-consuming and can vary between observers. This study investigates an automated method for O-RADS scoring using a large language model (LLM) to analyze narrative ultrasound reports. METHODS:A two-stage pipeline was developed for automated O-RADS classification. Initially, the Lingshu LLM, specialized in medical language, extracted and embedded features from free-text descriptions of ovarian lesions. It identified key diagnostic features mentioned by sonologists. Subsequently, these features were used to train and evaluate several machine learning algorithms, including logistic regression (LR), support vector machines and random forests, to predict O-RADS scores (1-5). RESULTS:The proposed method was evaluated on a dataset of 513 cases using fivefold cross-validation. The pipeline using Lingshu model embeddings with LR achieved the highest accuracy of 0.803 [95% CI: 0.753, 0.853], a weighted-average F1-score of 0.819 [95% CI: 0.777, 0.861] and a macro-averaged AUROC of 0.948 [95% CI: 0.937, 0.959]. This outperformed the MedGemma model's pipeline, which had an accuracy of 0.760 [95% CI: 0.700, 0.820], F1-score of 0.787 [95% CI: 0.739, 0.835] and AUROC of 0.941 [95% CI: 0.911, 0.971]. CONCLUSION:This study introduces a novel approach to automate O-RADS scoring using LLMs for feature extraction and traditional machine learning for classification. The results indicate that this method can accurately stratify ovarian cancer risk, potentially improving clinical workflow efficiency and reducing diagnostic variability. This approach may support radiologists in making more consistent and timely assessments.

OBJECTIVES:To compare perioperative outcomes, complications, aesthetic results, and patient-reported satisfaction among breast-conserving surgery (BCS), endoscopic nipple-sparing (ENS) mastectomy with immediate implant-based reconstruction, and open nipple-sparing (ONS) mastectomy, and to identify factors independently associated with aesthetic outcome. METHODS:This retrospective study included 160 early-stage breast cancer patients (BCS=100, ENS=30, ONS=30). Perioperative outcomes, complications classified according to the Clavien-Dindo system, oncologic safety, aesthetic scores, and BREAST-Q domains were analyzed. Multivariable regression analysis was performed to identify predictors of aesthetic outcomes. A 1:1 propensity score-matched sensitivity analysis (30 pairs) was conducted, which confirmed significantly reduced blood loss in the ENS group (P<0.001), and showed a numerical but non-significant difference in aesthetic scores (P=0.088). RESULTS:The ENS group had the longest operative time (159.2 min), whereas the ONS group experienced the greatest intraoperative blood loss (72.5 ml). Patients in the BCS group had the shortest drainage and hospital stay (both P<0.001). The overall complication rates were 7.0% in BCS group, 20.0% in the ENS group, and 16.7% in the ONS group. Aesthetic scores were highest in the BCS group (84.9), followed by the ENS group (79.2) and the ONS group (75.8) (all P<0.001). BREAST-Q scores demonstrated a similar pattern. No significant differences were observed among groups regarding margin positivity or short-term recurrence. Multivariable analysis identified surgical approach, complications, and tumor location as independent predictors of aesthetic outcomes. CONCLUSION:BCS remains the preferred option for eligible patients with early-stage breast cancer. For patients unsuited to BCS, ENS is associated with significantly lower intraoperative blood loss than ONS. While aesthetic scores showed a favorable trend in the ENS group, this difference did not reach statistical significance in the propensity score-matched analysis.

Breast cancer is a leading cause of cancer-related death in women, and the development of effective treatments for advanced disease remains a critical challenge. Metastasis, the spread of cancer cells to distant sites, is the major cause of mortality in breast cancer. We identified a novel role for the G protein-coupled receptor 107 (GPR107) in promoting breast cancer invasion and metastasis. Furthermore, we found that GPR107 mediates a reduction in collagen Ⅳ (COL4), a key component of the extracellular matrix (ECM) that normally restricts tumor cell invasion. This reduction in COL4 levels was associated with GPR107 mediating the Clathrin-mediated endocytosis of COL4 from the ECM, an increase in matrix metalloproteinase 2 (MMP2) production to degrade COL4 in the ECM, and a decrease in COL4 production. Mechanistically, we identified GPR107 as a key mediator of the ERK/STAT3 pathway activation through β-arrestin, leading to increased expression of MMP2 and suppression of COL4 gene transcription, effectively promoting invasion and metastasis in breast cancer cells. These findings suggest that GPR107 could serve as a promising biomarker for predicting breast cancer malignancy and a potential therapeutic target for preventing and treating metastatic disease.

Background Reperfusion is the most effective strategy for myocardial infarct, but induces additional injury. WD repeat and SOCS box containing protein 1 (WSB1) plays a protective role in ischemic cells. This study aims to investigate the effects of WSB1 on myocardial ischemia–reperfusion (IR) injury. Methods The myocardial IR was induced by left anterior descending (LAD) ligation for 45 min and subsequent reperfusion. The overexpression of WSB1 was mediated by tail vein injection of AAV9 loaded with WSB1 encoding sequence two weeks before IR surgery. H9c2 myocardial cells underwent oxygen-sugar deprivation/reperfusion (OGD/R) to mimic IR, and transfected with WSB1 overexpression or silencing plasmid to alter the expression of WSB1. Results WSB1 was found highly expressed in penumbra of myocardial IR rats, and the WSB1 overexpression relieved IR-induced cardio dysfunction, myocardial infarct and pathological damage, and cardiomyocyte death in penumbra. The ectopic expression of WSB1 in H9c2 myocardial cells mitigated OGD/R-caused apoptosis, and silencing of WSB1 exacerbated the apoptosis. In addition, WSB1 activated β-catenin signaling, which was deactivated under the ischemic condition. The co-immunoprecipitation results revealed that WSB1 mediated ubiquitination and degradation of glycogen synthase kinase 3 beta (GSK3β) as an E3 ligase in myocardial cells. The effects of WSB1 on myocardial cells under ischemic conditions were abolished by an inhibitor of β-catenin signaling. Conclusion WSB1 activated β-catenin pathway by promoting the ubiquitination of GSK3β, and restrained IR-induced myocardial injury. These findings might provide novel insights for clinical treatment of myocardial ischemic patients.

Purpose:Elucidation of the oncogenic role of SLC35A2 in human tumors and the potential function and clinical significance in breast cancer.Methods:Pan-cancer analysis was performed via various bioinformatics tools to explain the pathogenic role of SLC35A2. A prognostic nomogram was also developed based on the SLC35A2 expression and clinicopathological characteristics in breast cancer patients. In addition, the role of SLC35A2 was validated in breast cancer by in vivo and in vitro experiments.Results:SLC35A2 expression is increased in 27 tumor types, and its high expression is substantially correlated with poor prognosis in patients with a variety of cancers. Receiver operating characteristic (ROC) curves showed that SLC35A2 expression levels could accurately distinguish most tumor tissues from normal tissues. High SLC35A2 expression was linked to increased immune infiltration in myeloid-derived suppressor cells (MDSC), as well as immune checkpoints, ferroptosis-related genes, tumor mutational burden (TMB), and microsatellite instability (MSI). SLC35A2 may be involved in tumorigenesis by regulating the glycosylation process. Furthermore, multivariate Cox analysis showed that SLC35A2 was an independent prognostic factor for breast cancer. And the nomogram model had good predictive accuracy for the prognosis of breast cancer patients. Meanwhile, cellular experiments demonstrated that knockdown of SLC35A2 could significantly inhibit the proliferation, migration and invasion of breast cancer cells, while increasing the protein level of E-cadherin and decreasing N-cadherin. A nude mouse xenograft model showed that inhibition of SLA35A2 expression could significantly inhibit tumor growth.Conclusion:SLC35A2 has good diagnostic and prognostic values in multiple cancers and is closely related to tumor immune infiltration. In addition, SLA35A2 as an oncogene in breast cancer may be involved in the progression of epithelial mesenchymal transition (EMT).

ObjectiveThis stydy aims to assess the value of monitoring of postoperative neutrophil-to-lymphocyte ratio (NLR), D-dimer, and carbohydrate antigen 153 (CA153) for diagnosis of breast cancer (BC) recurrence and metastasis. Materials/MethodsA cohort of 252 BC patients who underwent surgery at the First Affiliated Hospital of Anhui Medical University between August 2008 and August 2018 were enrolled in this retrospective study. All patients were examined during outpatient follow-ups every 3 months for 5 years postoperation and every 6 months thereafter. Recurrence or metastasis was recorded for 131 patients but not for the remaining 121. Retrospective analysis of hematological parameters and clinicopathological characteristics allowed comparison between the two groups and evaluation of these parameters for the recurrent and metastatic patients. ResultsLymph node metastasis, higher tumor node metastasis (TNM) staging, and higher histological grade correlated with BC recurrence and metastasis (p < 0.05). Statistical differences were found in absolute neutrophil count (ANC), absolute lymphocyte count (ALC), CEA, CA153, D-dimer, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) between the recurrent and metastatic and control groups (p < 0.05). Logistic regression analysis showed that CA153, D-dimer, NLR, and TNM staging were risk factors for BC recurrence and metastasis (p < 0.05). Combined values for the NLR, D-dimer, and CA153 had good diagnostic values, giving the highest area under the curve (AUC) of 0.913. High NLR, D-dimer, and CA153 values were significantly associated with recurrence and metastasis at multiple sites, lymph node metastasis, and higher TNM staging (p < 0.05). Patients with high CA153 were more likely to have bone metastases (p < 0.05), and those with high D-dimer were prone to lung metastasis (p < 0.05). With the increasing length of the postoperative period, the possibility of liver metastases gradually decreased, while that of chest wall recurrence gradually increased (p < 0.05). ConclusionMonitoring postoperative NLR, D-dimer, and CA153 is a convenient, practical method for diagnosing BC recurrence and metastasis. These metrics have good predictive value in terms of sites of recurrence and metastasis and the likelihood of multiple metastases.

IntroductionBreast cancer (BC) is now the most common type of cancer in women. Disulfidptosis is a new regulation of cell death (RCD). RCD dysregulation is causally linked to cancer. However, the comprehensive relationship between disulfidptosis and BC remains unknown. This study aimed to explore the predictive value of disulfidptosis-related genes (DRGs) in BC and their relationship with the TME.MethodsThis study obtained 11 disulfidptosis genes (DGs) from previous research by Gan et al. RNA sequencing data of BC were downloaded from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus database (GEO) databases. First, we examined the effect of DG gene mutations and copy number changes on the overall survival of breast cancer samples. We then used the expression profile data of 11 DGs and survival data for consensus clustering, and BC patients were divided into two clusters. Survival analysis, gene set variation analysis (GSVA) and ss GSEA were used to compare the differences between them. Subsequently, DRGs were identified between the clusters used to perform Cox regression and least absolute shrinkage and selection operator regression (LASSO) analyses to construct a prognosis model. Finally, the immune cell infiltration pattern, immunotherapy response, and drug sensitivity of the two subtypes were analyzed. CCK-8 and a colony assay obtained by knocking down genes and gene sequencing were used to validate the model.ResultTwo DG clusters were identified based on the expression of 11DGs. Then, 225 DRGs were identified between them. RS, composed of six genes, showed a significant relationship with survival, immune cell infiltration, clinical characteristics, immune checkpoints, immunotherapy response, and drug sensitivity. Low-RS shows a better prognosis and higher immunotherapy response than high-RS. A nomogram with perfect stability constructed using signature and clinical characteristics can predict the survival of each patient. CCK-8 and colony assay obtained by knocking down genes have demonstrated that the knockdown of high-risk genes in the RS model significantly inhibited cell proliferation.DiscussionThis study elucidates the potential relationship between disulfidptosis-related genes and breast cancer and provides new guidance for treating breast cancer.

Background Long non-coding RNAs (lncRNAs) play vital roles in tumorigenesis. Here, we explored how lncRNA HOXA11-AS functions in the progression of breast cancer (BC). Methods HOXA11-AS and miR-125a-5p levels were measured by a quantitative real-time polymerase chain reaction, whereas western blotting determined TMPRSS4 levels in BC tumor tissues, adjacent normal tissues and BC cell lines. The roles of HOXA11-AS, miR-125a-5p and TMPRSS4 in BC proliferation were investigated using cell counting kit-8, colony formation and flow cytometry assays, whereas scratch and transwell assays were used to measure metastasis. RNA pull-down assays and dual-luciferase assays assessed direct interactions between HOXA11-AS and miR-125a-5p. The effects of HOXA11-AS in vivo were investigated in a BC xenograft model. Results HOXA11-AS was upregulated in tumor tissues of 56 BC patients compared to adjacent non-tumor tissues, with high levels being associated with worse overall survival. Silencing of HOXA11-AS inhibited the proliferation and metastasis of BC cells, leading to cell cycle arrest in G0/G1 and induction of apoptosis. We identified miR-125a-5p as a target of HOXA11-AS, with miR-125a-5p inhibitors partially restoring the reduction of cell proliferation and metastasis induced by HOXA11-AS silencing. We also determined that miR-125a-5p targeted TMPRSS4 mRNA, with HOXA11-AS knockdown and miR-125a-5p mimics suppressing TMPRSS4. Overexpression of TMPRSS4 partially compensated for the reduction of cell proliferation and metastasis induced by HOXA11-AS silencing. Finally, we confirmed the mechanism of HOXA11-AS in the regulation of tumorigenesis in the mouse model. Conclusions HOXA11-AS regulates the tumorigenic ability of BC via the miR-125a-5p/TMPRSS4 axis. This provides insights for regulatory mechanisms involved in BC progression, and may enable new treatment strategies in the clinical setting.

Background Breast cancer (BC) accounts for a significant share of cancer-related deaths worldwide. Ongoing investigations have shown that long non-coding RNAs (lncRNAs) drive BC progression but their underlying mechanisms remain largely undescribed. LncRNA KCNQ1OT1 was previously identified in BC but its functional significance remained to be fully investigated. Methods KCNQ1OT1 and its downstream target genes were analyzed in breast cancer tissues and cell lines using methods including RT-qPCR, immunohistochemistry and Western blotting. The effects of KCNQ1OT1, miR-34a and Notch3 on BC cells were investigated using assays measuring proliferation (CCK-8, colony formation), apoptosis, and migration/invasion (scratch and Transwell assays). MS2-RIP and dual-luciferase reporter assays were used to study RNA interactions. Xenograft studies were employed to define the tumorigenic potential of KCNQ1OT1 in vivo. Results KCNQ1OT1 expression was up-regulated in BC tissues and high levels were associated with poorer prognosis. ShRNA inhibition of KCNQ1OT1 expression in BC cell lines retarded proliferation, migration and invasion in vitro and tumor growth in vivo. Up-regulation of KCNQ1OT1 was shown to inhibit miR-34a which was associated with blocking the inhibitory effect of miR-34a on BC cell proliferation, migration and invasion. Notch3 was found to be a downstream target of miR-34a with KCNQ1OT1 markedly inducing Notch3 expression in BC. Evidence for KCNQ1OT1/miR-34a/Notch3 axis was further established in clinical BC samples. Conclusion We identified a KCNQ1OT1/miR-34a/Notch3 axis which promotes BC progression through effects on cell proliferation and metastasis that was further associated with poor patient prognosis. These results propose targeting this axis as novel treatment approach for BC.

Breast cancer is the most common malignant tumor in the population, and the incidence of young breast cancer patients is gradually increasing. With the increasing requirements of patients for cosmetic effect after tumor resection, the traditional breast conserving surgery can no longer meet the treatment needs of patients. Breast-conserving plastic surgery for breast cancer has been proved to be safe in oncology, but there are still many deficiencies. Therefore, it is very important for surgeons and patients to develop unified and repeatable standard guidelines for breast-conserving plastic surgery of breast cancer.

BackgroundDiastolic wall shear stress (WSS), assessed by using vector flow mapping (VFM), is the result of the interaction between the blood flow and the ventricular wall. This study aimed to evaluate the trend of left ventricular (LV) WSS in normal subjects.Methods and resultsA total of 371 healthy volunteers were recruited and divided into four age groups (group I: 18–30 years; group II: 31–43 years; group III: 44–56 years; group IV: 57–70 years). LV WSS of different age groups was measured at each diastolic phase (P1: isovolumic diastolic period, P2: rapid filling period, P3: slow filling period, and P4:atrial contraction period) to evaluate the change trend of LV WSS. In each age group, LV WSS coincided with a trend of increasing-decreasing-increasing during P1–P4 (P < 0.05). Besides, among groups I, II, III, and IV, WSS of anterolateral, inferoseptal, and anteroseptal in P1 and WSS of inferolateral, inferoseptal, and anteroseptal in P4 all showed an increasing trend with age (P < 0.05). Regarding sex differences, women had greater diastolic WSS compared to men (P < 0.05).ConclusionLV WSS showed a regular variation and had specific age- and sex-related patterns in different diastolic phases.

BackgroundPathological complete response (pCR) is considered a surrogate for favorable survival in breast cancer (BC) patients treated with neoadjuvant chemotherapy (NACT), which is the goal of NACT. This study aimed to develop and validate a nomogram for predicting the pCR probability of BC patients after NACT based on the clinicopathological features. MethodsA retrospective analysis of 527 BC patients treated with NACT between January 2018 and December 2021 from two institutions was conducted. Univariate and multivariate logistic regression analyses were performed to select the most useful predictors from the training cohort (n = 225), and then a nomogram model was developed. The performance of the nomogram was evaluated with respect to its discrimination, calibration, and clinical usefulness. Internal validation and external validation were performed in an independent validation cohort of 96 and 205 consecutive BC patients, respectively. ResultsAmong the 18 clinicopathological features, five variables were selected to develop the prediction model, including age, American Joint Committee on Cancer (AJCC) T stage, Ki67 index before NACT, human epidermal growth factor receptor 2 (HER2), and hormone receptor (HR) status. The model showed good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.825 (95% CI, 0.772 to 0.878) in the training cohort, and 0.755 (95% CI, 0.658 to 0.851) and 0.79 (95% CI, 0.724 to 0.856) in the internal and external validation cohorts, respectively. The calibration curve presented good agreement between prediction by nomogram and actual observation, and decision curve analysis (DCA) indicated that the nomogram had good net benefits in clinical scenarios. ConclusionThis study constructed a validated nomogram based on age, AJCC T stage, Ki67 index before NACT, HER2, and HR status, which could be non-invasively applied to personalize the prediction of pCR in BC patients treated with NACT.

目的:探讨治疗早期乳腺癌患者采用保乳术与改良根治术的临床价值.方法:选取2018年6月到2021年6月期间我院收治的早期乳腺癌患者,共计60例,双色球分组法均分2组,对照组采取改良根治术治疗,研究组患者采取保乳术治疗,对比患者治疗效果和预后情况.结果:研究组患者各项手术指标均较对照组更优;研究组患者术后美容效果显著较对照组更优,P＜0.05.结论:对早期乳腺癌患者采取保乳术疗效确切且美容效果较好,建议推广应用.

乳腺癌乳房成形术是指在确保乳腺肿瘤安全切除的情况下,与肿瘤整形技术相结合从而达到最佳的美容效果.狭义的层面是指部分象限切除联合乳房局部组织或腺体的重排即保乳;广义层面上是指保乳或全乳切除术后乳房重建,而乳房重建又可分为自体皮瓣重建及植入物重建,同时还包括脂肪移植、生物材料等重建辅助技术.在国外,除少数晚期乳腺癌病人,70％以上的病人接受了乳房再造.2018 年,中国抗癌协会乳腺癌专业委员会、中国医师协会外科医师分会乳腺外科医师委员会发布一项关于2017 年全国乳腺癌年手术量大于200例的医院调研显示,约80％以上的医院开展了乳房重建术,但全乳术后接受乳房成形术仅10％左右[1].选择何种乳房成形策略是一个高度个性化的过程,需要考虑病人自身乳房特征、健康状况、乳癌的治疗方案和病人个人意愿.如何把握正确的乳房成形时机和方法需要医生与病人、肿瘤学专家和整形专家等多学科专家团队的良好沟通和合作.

Here, we report a 26-year-old Chinese woman diagnosed with breast cancer. The patient expressed her concern for possible impact on fertility, as well as the cosmetic outcomes of the surgery. Therefore, the patient was consulted for preserving fertility function by cryopreservation after ovariectomy, with sentinel lymph node biopsy and breast reconstruction surgery simultaneously. With the development of health care and the growth of economy, as well as the general awareness of full-round health, the need for reproductive preservation of young female breast cancer patients in developing countries is also increasing. Thus we recommend actively providing patent education for the reproductive protection operation on a regular basis, to reduce the cases of patients who suffer from a decline in fertility.

Background: Ischemia-reperfusion injury (IRI) seriously affects the prognosis of patients. We sought to use speckle tracking echocardiography (STE) to accurately evaluate the effect of drugs. Methods: In this study, STE was used to quantitatively evaluate the changes of myocardial function before and after reperfusion in myocardial ischemia rabbits with ischemia postconditioning (I-PostC) or ATP postconditioning. The variations of the left ventricular (LV) longitudinal, circumferential and radial myocardium were detected by STE technique. Meanwhile, a series of biochemical experiments were performed including myocardial enzymes assay, myocardial infarction size assay and TUNEL assay. Results: After ligation of coronary artery for 45 min, the strain and strain rate curves of left ventricular myocardium was disordered. The most STE parameters were significantly diminished and the time of reaching peak was delayed. After reperfusion for 120 min, the parameters (longitudinal, circumferential, radial strain and strain rate, as well as ventricular torsion function) were obvious recovery in I-PostC and ATP postconditioning groups. The sensitivity and specificity of global circumferential peak strain (GCSp), global longitudinal peak strain (GLSp), peak twist (Ptw) and peak twisting velocity (PTV) to diagnose myocardial infarction rabbits were 86.1% and 75%, 79.2% and 72.5%, 79.2% and 75%, 66.7% and 70.8%, respectively. The levels of aspartate aminotransferase (AST) and creatine phosphokinase isozyme (CKMB) were up-regulated in I/R group. AST and lactate dehydrogenase (LDH) values significantly reduced in the other three groups. The Bax expression was decreased, simultaneously, the Bcl-2 expression was increased after I-PostC and ATP postconditioning treatment. Conclusions: The application of STE in the assessment of IRI has high accuracy and reproducibility. Therefore, ATP has an important clinical value as a pharmacologic postconditioning drug.

Background: FAS cell surface death receptor (FAS) gene has 2 common single nucleotide polymorphisms (SNPs) in its promoter, FAS-1377> A (rs2234767) and FAS-670A > G (rs1800682). Several studies have investigated the role of these 2 polymorphisms in etiology of breast cancer in Asian population while the outcomes are inconsistent. To derive a more precise assessment of the association between breast cancer susceptibility with FAS gene promoter SNPs, a meta-analysis of published studies was performed. Material and methods: We systematically searched PubMed, Embase, Web of Science, and the Chinese biomedical database (CBM) for papers published until November 1, 2018. Odds ratio (OR) with 95% confidential interval (95%CI) was conducted to evaluate the associations. Statistical analysis was conducted using Stata 13.0 software. A total of 8 studies covering 2564 cases and 2633 controls were included. Results: The integrated results suggest the following: For the FAS-1377G/A polymorphism, we only found significant associations for allele G vs allele A (OR=1.100, 95%CI=1.004-1.206, P=.040). After stratification by ethnicity, a significant association was observed only for the AA+GA vs GG genotype in East Asian populations (OR=1.177, 95% CI=1.010-1.371, P=.037). The association was not found in West Asian populations. For the FAS -670A/G polymorphism, no association with cancer risk was found in any comparison model. Sensitivity analysis suggests that the meta-analysis results obtained after excluding any single study were similar to the original ones, suggesting that the meta-analysis results were not significantly affected by any single study. Conclusion: These results indicated that FAS-1377G/A polymorphism may contribute to the increased breast cancer susceptibility and could be a promising target for cancer risk prediction. Further studies are needed to determine if the FAS gene confers a risk of breast cancer in other ethnic groups, such as Africans and Latin Americans.
