Retrospective reevaluations have revealed errors in screening; moreover, advances in oncological therapy and a better understanding of the disease have raised doubts toward the efficacy of these procedures, which might also cause side effects alongside the risk of overdiagnosis and overtreatment. On the other hand, the lack of information or even misinformation might cause confusion among the potential beneficiaries of these procedures, particularly the patients. These procedures are constantly being recommended by institutions, but the possible risks accompanied by these procedures are often not explained. It is easy to promote mammography screening if the majority believe that it reduces the risk of breast cancer and saves lives. Unfortunately, this is not the case. Many critics of screening are now demanding clear and precise explanations of the procedure and emphasizing on the importance of physical examination. Women must make informed decisions before screening by discussing their own risk profile, the possible benefits, and the eventual risks and harms of mammogram with their physicians. Women should be classified into two groups: those who would gain potential benefits from the procedure and those whose risks outweigh the benefits. A screening program that clearly does not offer more benefits than risks cannot be implemented by public heath institutions. Providing complete and unbiased information, promoting appropriate care, as well as preventing overdiagnosis and overtreatment would be the best option.","PeriodicalId":94260,"journal":{"name":"Tumor discovery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90627111","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}

N6-methyladenosine (m6A) and long non-coding RNA (lncRNA) play important roles in the prognostic value and immunotherapy response of pancreatic adenocarcinoma (PAAD). Therefore, it is crucial to recognize m6A-related-lncRNAs in PAAD patients. In this study, m6A-related lncRNAs were obtained by coexpression analysis. Univariate, the Least Absolute Shrinkage, and Selection Operator (LASSO) and multivariate Cox regression analyses were performed to construct m6A-related lncRNA prognostic models. Kaplan–Meier analysis, principal component analysis, feature-rich annotation, and nomogram were used to analyze the accuracy of risk models. Potential drugs targeting this model are also discussed. A prognostic model based on m6A-related lncRNAs was constructed, potential drugs targeting this m6A-related lncRNAs feature were discovered, and the relationship with immunotherapy response was studied. Finally, a nomogram was established to predict survival in PAAD patients. This m6A-based lncRNAs risk prognostic model may be promising for clinical prediction of prognosis and immunotherapy response in PAAD patients.","PeriodicalId":94260,"journal":{"name":"Tumor discovery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80856349","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 root cause of the development of cervical lymphangioma is the congenital malformation of the developing lymphatic system. Cystic hygroma is benign in nature and the cause in adults is still unclear. The most common site of origin is in head and neck region, and cystic hygroma accounts for 75% of lymphatic malformations. The most common presentation of cystic hygroma is painless swelling with ill-defined lesion, most commonly located at the posterior triangle of the neck. The common age group is between birth and 2 years of age, with very rare presentation in adults. Hence, it is necessary to rule out all differential diagnosis of cervical lymphangioma, which is presented with cystic neck swelling.

Therefore, the use of lower TMX doses utilizing nano-enabled drug delivery systems offers multiple benefits to improving drug specified concentration, safety, and long-term release. In this study, we synthesized targeted magnetic nanoparticles (MNPs) containing folic acid (FA) and hyaluronic acid (HA) to improve drug delivery of TMX. After investigations utilizing Fourier-transform infrared spectroscopy and field emission scanning electron microscope, we found that the surface of MNPs was well modified with targeting agents, and the size of the Fe3O4-DPN-HA-FA NPs was determined at ∼153 (±3.3) nm. Furthermore, the release of 81% TMX after 120 h indicated that there was a controlled pattern of drug release from the modified MNPs. Besides that, the MTT assay revealed that the viability of MDA-MB-231 cell lines after 48 h and 72 h of treatment is dependent on the time and concentration of Fe3O4-DPN-HA-FA-TMX NPs. Finally, real-time polymerase chain reaction demonstrated that Fe3O4-DPN-HA-FA-TMX NPs could upregulate the expression of Bak1 genes and downregulated the expression of Bclx genes during 24 h treatment. All data confirmed that the presence of HA and FA on the surface of nanocarriers and the active targeting employing the nanocarriers can be a useful step to obliterate the breast cancer cells.","PeriodicalId":94260,"journal":{"name":"Tumor discovery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86914785","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}

Recently, several studies suggested that cancer patients may exhibit symptoms of cognitive impairment before, during and even many years after the completion of therapies, negatively impacting the quality of life and functional independence of cancer survivors. Clinically, the coexistence of cancer and cognitive impairment reminds scientists of paraneoplastic syndrome, especially limbic encephalitis. However, some cancer patients show symptoms of cognition deterioration after treatment, without any typical psychiatric symptoms, epileptic seizures or positive antineuronal antibodies, suggesting that the relationship between cancer and cognitive deficits is more common than previously anticipated. Most importantly, many aspects of the association between cancer and cognitive impairment remain uncertain. The definitive connection between systemic cancer and central nervous system is yet to be established. Therefore, this review summarizes the current evidence on the potential pathophysiology in these patients with cancer-related cognitive impairment, and reviews the knowledge gaps and the potential counteracting strategies.","PeriodicalId":94260,"journal":{"name":"Tumor discovery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85405629","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 findings imply that these receptors and their associated ligands play a significant role in the growth and spread of the tumor, hence impacting the prognosis and life expectancy of the affected individual. This comprehensive review uncovers promising evidence for the clinical use of these molecules, such as RAGEs, in prognostic considerations or as molecular targets for therapy.
