This study proposes NalexNet, a hybrid deep-learning classifier, to enhance classification accuracy and computational efficiency. The research methodology involves Vahadane stain normalization for preprocessing and Watershed segmentation for accurate tissue separation. The Teamwork Optimization Algorithm (TOA) is employed for optimal feature selection to reduce redundancy and improve classification performance. Furthermore, the NalexNet model is structured with convolutional layers and normal and reduction cells, ensuring efficient feature representation and high classification accuracy. Experimental results demonstrate that the proposed model achieves a precision of 99.9% and an accuracy of 99.5%, significantly outperforming existing models. This study contributes to the development of an automated and computationally efficient CC classification system, which has the potential for real-world clinical implementation, aiding pathologists in early and accurate diagnosis.","PeriodicalId":9463,"journal":{"name":"Cancer Investigation","volume":" ","pages":"1-19"},"PeriodicalIF":1.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143771398","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}

Despite advancements, radiation dermatitis remains a challenge, disrupting treatment schedules and compromising patients' quality of life. Exploring herbal compounds, particularly Curcumin, has shown promise in addressing radiation-induced dermatitis, with its non-toxic and anti-inflammatory properties offering the potential for clinical trials to prevent these reactions.Methods: This phase II randomized, double-blinded, placebo-controlled trial focused on adult females undergoing conventional fractionated RT. The main objective was to assess the efficacy of topical Curcumin in reducing the severity of radiation dermatitis.Results: During a five-month study, 52 breast cancer patients completed the research. Participants were divided into Curcumin and placebo groups. In the first week, a significant difference in redness (P-value = 0.001) and irritation (P-value = 0.017) was observed, with the Curcumin group showing lower percentages. This trend continued in the second, third, and fourth weeks (P-value = 0.001). No statistical difference was found in itching (P-value = 0.446), and the occurrence of dryness (P-value = 1.000) remained constant in both groups throughout the four weeks. In pain the differences were significant in the second, third, and fourth weeks (P-value = 0.001).Conclusion: The study highlights the success of a 2% Curcumin gel in reducing skin side effects during breast cancer radiation therapy, suggesting its potential to enhance patients' quality of life.Trial registration: IRCT20181208041882N3, 06/11/2020 (https://en.irct.ir/trial/49228).","PeriodicalId":9463,"journal":{"name":"Cancer Investigation","volume":" ","pages":"1-10"},"PeriodicalIF":1.8,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143718110","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}

At present, genomic testing is mainly confined to research settings, with samples sent to biopharmaceutical companies for analysis. The ever-expanding catalogue approved of targeted therapies has created an urgent unmet need for local genomic testing facilities, to enable upscaling of testing. Here, we compare the outcomes of local (IonTorrent™) and commercial (Foundation Medicine) genomic testing collected from 30 cancer patients in from plasma and tissue samples. Overall concordance was high in both tissue (98%) and plasma (94.2%). Variants identified by both platforms had a strong correlation in variant allele frequencies (VAF%): plasma: r = 0.99 p < 0.0001, tissue: r = 0.91 p < 0.0001. However, numerous low VAF% variants resulted in low positive percentage agreement (tissue 78.8% plasma 16.1%) and positive predictive values (tissue 56.3% plasma 71.4%). Local sequencing demonstrated higher fidelity in detecting fusions but low fidelity in detecting indels. Overall, this study supports the use of local genomic testing for routine molecular diagnostics but highlights outstanding issues before widespread implementation. Processing of variants detected at low VAF% and the limit of detection of assays needs to be addressed. Construction of gene panels requires careful consideration, including incorporation of markers of genomic instability.","PeriodicalId":9463,"journal":{"name":"Cancer Investigation","volume":" ","pages":"119-140"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482356","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}

Despite this, people living with HIV (PLWH) are often excluded from clinical trials. Here we analyze the change in clinical trial exclusion among PLWH resulting from multilateral advocacy efforts since 2017.Methods: We identified all US-based clinical trials with the keyword \"lymphoma\" with start dates between January 01, 2014 and January 04, 2025 using the publicly available NIH Clinical Trial Database (https://www.clinicaltrials.gov/). All studies with aggressive B-cell NHL subtypes were included. Regression models were performed to analyze descriptive factors.Results: 1,973 US-based clinical trials were captured, of which 945 met criteria for further analysis. PLWH were excluded from 59% pre-2018 versus 48% post-2018. After multivariate adjustment, NIH-funded trials (24% exclusion rate, p < 0.001), other funders (64% exclusion rate), and studies initiated post-2018 (48% exclusion rate, p < 0.001) were associated with inclusion, while CAR-T-related studies (62% exclusion rate, p < 0.05) were associated with exclusion.Conclusions: Likely partly due to advocacy from ASCO, NCI, and NCCN, there was a significant decrease in exclusion among PLWH in US-based NHL clinical trials. Future research should analyze the safety and efficacy of immunotherapy in PLWH to foster inclusion and reduce stigma among physicians and researchers.","PeriodicalId":9463,"journal":{"name":"Cancer Investigation","volume":" ","pages":"141-148"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143373845","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}

This study aims to identify and analyze the search for healthcare related to the prevention of breast/gynecological cancer among Brazilian lesbian cisgender women who have not had the disease. Seven lesbian women participated in this qualitative study. Semi-structured interviews were conducted and subsequently transcribed and analyzed following the reflexive thematic analysis approach and the theoretical framework of gender studies. Two thematic axes were constructed: gynecological appointments, which includes the subthemes follow-ups, types of exams, and struggles with the healthcare system, and meeting health professionals, which includes relationships with professionals, searching for professionals, discussing sexual orientation, and (un)preparedness. The participants in this study reported visiting a gynecologist at least once and doing preventive exams, although the frequency of these appointments varied for each woman.

In low-resource settings, where healthcare disparities are exacerbated by limited resources, cost-effective and efficient diagnostic methods are essential for bridging these gaps and ensuring better outcomes. Among the diagnostic tools evaluated among 23 patients sample, RT-PCR demonstrated superior sensitivity (100%) and the shortest turnaround time (7 days), significantly outperforming FISH and karyotyping in both accuracy and timeliness. This capability of RT-PCR to provide reliable and rapid results enables earlier treatment initiation, which is critical in managing these aggressive leukemias. Simplified statistical reporting underscores RT-PCR's unmatched sensitivity, while FISH and karyotyping, though useful, showed moderate performance with longer delays. By adopting RT-PCR as the primary diagnostic tool in LMICs, healthcare systems can make faster and more accurate treatment decisions, reduce overall treatment costs by avoiding diagnostic delays, and ultimately improve survival rates in pediatric leukemia patients.","PeriodicalId":9463,"journal":{"name":"Cancer Investigation","volume":" ","pages":"161-171"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027994","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}

Additionally, the review explains the tumor microenvironment's influence on apoptosis and its implications for cancer therapy resistance. Understanding the complex interplay between apoptotic signaling and cellular responses is crucial for developing targeted therapies that can effectively manage diseases associated with apoptosis dysregulation. The effects of conventional therapeutics and alternative substances with natural sources such as herbal compounds, alongside vitamins, minerals, and trace elements on cellular homeostasis and disease pathogenesis have been thoroughly investigated. Moreover, recent advances in therapeutic strategies aimed at modulating apoptosis are discussed, with a focus on novel interventions such as nutrition bio shield dietary supplement. These emerging approaches offer potential benefits beyond conventional treatments by selectively targeting apoptotic pathways to inhibit cancer progression and metastasis.
