Methods This retrospective study included 333 patients with histopathologically confirmed breast lesions, randomly split into training (N=266) and testing (N=67) datasets. Eight models, including four deep learning models (ORResNet101, ORMobileNet_v2, SRResNet101, SRMobileNet_v2) and four machine learning models (OR_LR, OR_SVM, SR_LR, SR_SVM), were developed based on original and super-resolution images. The best performing model was SRMobileNet_v2, which was used to construct a nomogram integrating clinical factors. The performance of nomogram was evaluated using receiver operating characteristic (ROC) analysis, decision curve analysis (DCA), and calibration curves. Results SRMobileNet_v2, MobileNet_V2 based on super-resolution ultrasound images, had the best predictive performance in four traditional machine learning models and four deep learning models, with AUC improvements of 0.089 and 0.031 in the training and testing sets, relative to the ORMobileNet_v2 model based on original ultrasound images. The deep-learning nomogram was constructed using the SRMobileNet_v2 model score, tumor size, and patient age, resulting in superior predictive efficacy compared to the nomogram without the SRMobileNet_v2 model score. Furthermore, it demonstrated favorable calibration, discrimination, and clinical utility in both cohorts. Conclusion The diagnostic prediction model utilizing super-resolution reconstructed ultrasound images outperforms the model based on original images in distinguishing between benign and malignant breast lesions. The nomogram based on super-resolution ultrasound images has the potential to serve as a reliable auxiliary diagnostic tool for clinicians, exhibiting superior predictive performance in distinguishing between benign and malignant breast lesions.","PeriodicalId":9106,"journal":{"name":"Breast Cancer : Targets and Therapy","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138615519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods This is a prospective observational study conducted in two general hospitals in West Java, Indonesia. The research subjects in this study were early-stage breast cancer patients with no lymph node metastasis (N0) who had undergone a biopsy. There were 83 study subjects included in this study. The sentinel lymph node biopsy was taken after injection of methylene blue into the peritumoral area. Blue nodes in the axilla were marked as positive lymph node biopsy results and sent for histopathology examination.

Chemical compounds of various types have been identified in the Red Sea marine sponge Xestospongia testudinaria, including sterol esters, sterols, indole alkaloids, and brominated polyunsaturated fatty acids. These compounds have demonstrated promising biological features, which in cludes anti-inflammatory, cancer preventive, and antioxidant capacities. Methods The cytotoxic potential of Xestospongia testudinaria was assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and morphological alterations in MCF-7 cell line. Furthermore, the flow cytometry was also utilized to assess apoptosis and identify changes in the cell cycle; besides, cell migration was assessed by scratch wound-healing assay. Results A significant dose-dependent decrease in the percentage of MCF-7 cell viability was observed with IC50 39.8 ug/mL. Functional studies were performed on MCF-7 to show that Xestospongia testudinaria raises apoptotic cell death and induces growth arrest at the G1/G0 while inhibiting cell migration in scratch assay. Conclusion These results demonstrated that Xestospongia testudinaria extract has an inhibitory effect on breast cancer cells proliferation, migration and induce apoptosis. Thus, it holds great promise as a potential treatment for breast cancer.","PeriodicalId":9106,"journal":{"name":"Breast Cancer : Targets and Therapy","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138610101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
