Conventional chemotherapy regimens are often limited by their high toxicity, the cancer’s drug resistance, and the challenge of managing independently evolving multifocal spread. In this context, a repurposing strategy is particularly enticing. It allows for the introduction of a drug with a known safety profile, thus significantly reducing the costs and time necessary to introduce a new treatment. Nitroxoline (NIT), a drug with a well-established pharmacokinetic profile known for over 50 years and utilised in treating uncomplicated urinary tract infections, has recently garnered attention for its potential oncologic applications. Given the pharmacokinetic properties of NIT, our focus was specifically on urologic cancers in which its excretion profile is most advantageous. We examined all available studies, demonstrating significant effectiveness of NIT in inhibiting angiogenesis, tissue invasion, metastasis formation, and counteracting multidrug resistance. The efficacy and mechanism of action of NIT were found to vary across different cell lines. The findings to date are promising, suggesting that NIT or its derivatives could play a role in oncology, although further research is necessary to fully understand its potential and applicability in cancer treatment.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"115 23","pages":"1 - 8"},"PeriodicalIF":0.0,"publicationDate":"2024-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141124409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Illness frequently causes radical changes both in patients’ lives and in their closest family situation. It often threatens currently performed tasks or values pursued by patients and those who support them. The aim of the study was to determine the relationship between the health condition of people supporting leukaemia patients, strategies for coping with stress, and the level of subjective resources. Material and methods The research involved 100 people supporting leukaemia patients. The methods used in the research included a standardised interview, CISS SES, SOC-29 and ISCL-STAI questionnaires, as well as Bryant’s perceived control of life questionnaire. Results The results show that the health of people supporting leukaemia patients is largely conditioned by emotion-focused style (β= –0.276, p = 0.007) and avoidant attachment style linked to social anxiety (β = 0.444, p = 0.012). As regards the resources, a significant negative health predictor in people supporting leukaemia patients is the anxious personality type (β = –0.375, p = 0.001), whereas a positive health predictor is the sen-se of support provided by others (β = 0.281, p = 0.001). Conclusions People supporting leukaemia patients point to the key role of the subjective resources possessed by an individual. Concentration on negative emotions and deficient resources, in particular the anxious personality, are definitely detrimental to health.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":" 26","pages":"71 - 74"},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141128887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coffee is one of the most popular beverages that are globally consumed. It consists of several phytochemical constituents, such as polyphenols, caffeine, and chlorogenic acid (CGA). Those constituents account for the potential effects on several diseases, including cancer. It has been reported that coffee exerts significant cytotoxicity against OSCC via inhibition of epidermal growth factor receptor tyrosine kinase (EGFR-TK) and up-regulation of apoptotic proteins, such as caspase-3 and caspase-9. The current study aims to measure the concentration of caffeine and CGA in 3 different types of coffee extracts, unroasted green coffee (GC), medium-roasted coffee (MRC), and decaffeinated coffee. Material and methods The cytotoxic effect against OSCC-25 cell lines was evaluated and correlated with the concentration of constituents in each extract. The mechanisms of cytotoxicity were also studied by assessing the effect of each extract on caspase-3 and caspase-9 levels, in addition to the inhibitory effect on EGFR-TK. Results It was found that the caffeine concentration was higher in MRC than in GC because of the roasting process. However, the concentration of caspase-3 and -9 and the inhibitory effect on EGFR-TK were much higher in GC than MRC-treated cells because of the higher concentration of CGA. Conclusions Decaffeinated coffee exerts lower cytotoxic effects because it was totally deprived of caffeine and CGA during the decaffeination process.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":" 5","pages":"63 - 70"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is critical to identify potent therapeutic targets and prognostic markers to detect high-risk patients. Material and methods We assessed the immunohistochemical expression of protein disulphide isomerase A3 (PDIA3) and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in 50 cases of cervical carcinoma, and we investigated their association with clinicopathological characteristics. Results High PDIA3 was detected in 50% of cases, and statistical analysis revealed a positive correlation between high PDAI3 expression and tumour grade (p < 0.001) and large tumour size (p = 0.010), depth of stromal invasion (p = 0.017), lymph-vascular invasion (p = 0.005), parametrial invasion (p < 0.001), nodal metastasis (p < 0.001), and higher International Federation of Gynaecology and Obstetrics stages (p < 0.001). Positive nuclear expression of p-STAT3 was detected in 44% of cases and showed significant association with histological grade (p = 0.036), tumour stage (p = 0.021), nodal metastasis (p = 0.020), and parametrial invasion (p = 0.045); statistical analysis of the patient’s survival data revealed that shorter overall survival and disease-free survival, S, were associated with high PDIA3 expression and positive p-STAT3 immunoexpression. Conclusions The high expression of PDIA3 and p-STAT3 was related to highly aggressive cervical carcinoma with poor prognosis, and high risk of recurrence after the standardised protocol of treatment. Hence, both PDIA3 and p-STAT3 could be considered as novel biomarkers for tumour progression and promising targets in the management of cervical carcinoma patients.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":" 31","pages":"51 - 62"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the main cause of death due to non-melanoma skin cancer every year. Metastatic cutaneous SCC is associated with poor prognosis in patients and warrants a more effective and specific approach such as disruption of genes associated with cancer metastasis. Material and methods Matrix metalloproteinases (MMPs) are enzymes involved in cancer progression and are regarded as major oncotargets. Among others, MMP9 plays critical roles in tumour progression, angiogenesis, and invasion of cutaneous SCC. We aimed to determine whether the MMP9 gene is a suitable gene target for anti-cancer therapy for cutaneous SCC. We performed clustered regularly interspaced short palindromic repeat (CRISPR)-Cas9 transfection of guide RNA (gRNA) targeting the MMP9 gene into human cutaneous SCC cell line A431. Results Following CRISPR transfection treatment, the viability (p < 0.01) and migratory activities (p < 0.0001) of in vitro cutaneous SCC cells were found to be reduced significantly. The use of quantitative polymerase chain reaction (qPCR) also revealed downregulation of the mRNA expression levels of cancer-promoting genes TGF-β, FGF, PI3K, VEGF-A, and vimentin. Direct inhibition of the MMP9 gene was shown to decrease survivability and metastasis of cutaneous SCC cell line A431. Conclusions Our findings provided direct evidence that MMP9 is important in the viability, proliferation, and metastasis of cutaneous SCC cells. It serves as a positive foundation for future CRISPR-based targeted anti-cancer therapies in treating skin cancer and other forms of malignancies that involve MMPs as the key determinants.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"10 10","pages":"255 - 262"},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139958036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to assess the diagnostic and prognostic role of preoperative cfDNA concentration in the plasma samples of clear cell renal cell carcinoma (ccRCC) patients. Material and methods The preoperative plasma cfDNA concentration was assessed in ccRCC patients (n = 46) and healthy individuals (control group) (n = 17). The circulating free DNA concentration was reflected by the 90 bp DNA fragments determined by real-time polymerase chain reaction. Results The median cfDNA concentration was significantly higher in ccRCC patients (n = 46) compared to the control g roup (n = 17) (2588 ±2554 copies/ml vs. 960 ±490 copies/ml, p < 0.01). In multivariate analysis, the preoperative plasma cfDNA concentration was the significant factor increasing the probability of ccRCC detection (OR: 1.003; 95% CI: 1.001–1.005).

Material and methods Samples from 5 primary LR-MDS (67 exons of SF3B1, U2AF1, SRSF2, ZRSR2, TET2, ASXL1, DNMT3A, TP53, and RUNX1 genes) were subjected to NGS. Next, a genomic study was performed to test for the presence of identified DNA sequence variants on a larger group of LR-MDS patients (25 bone marrow [BM], 3 saliva [SAL], and one peripheral blood [PB] sample/s). Both SSeq (all selected DNA sequence variants) and pyrosequencing (9 selected DNA sequence variants) were performed.

Material and methods A dataset of 3264 MRI brain images consisting of 4 categories: unspecified glioma, meningioma, pituitary, and healthy brain, was used in this study. Twelve convolutional neural networks (GoogleNet, MobileNetV2, Xception, DesNet-BC, ResNet 50, SqueezeNet, ShuffleNet, VGG-16, AlexNet, Enet, EfficientB0, and MobileNetV2 with meta pseudo-labels) were used to classify gliomas, meningiomas, pituitary tumours, and healthy brains to find the most appropriate model. The experiments included image preprocessing and hyperparameter tuning. The performance of each neural network was evaluated based on accuracy, precision, recall, and F-measure for each type of brain tumour. Results The experimental results show that the MobileNetV2 convolutional neural network (CNN) model was able to diagnose brain tumours with 99% accuracy, 98% recall, and 99% F1 score. On the other hand, the validation data analysis shows that the CNN model GoogleNet has the highest accuracy (97%) among CNNs and seems to be the best choice for brain tumour classification. Conclusions The results of this work highlight the importance of artificial intelligence and machine learning for brain tumour prediction. Furthermore, this study achieved the highest accuracy in brain tumour classification to date, and it is also the only study to compare the performance of so many neural networks simultaneously.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"1 3","pages":"230 - 241"},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139964694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
