RESUMEN

BACKGROUND/AIM: Wilms' tumors are pediatric renal tumors that generally have a good prognosis and outcomes. Viral illnesses have been linked to development of neoplasms and should be considered as a factor that could modulate overall survival. MATERIALS AND METHODS: We considered recently developed adaptive immune receptor, genomics and bioinformatics approaches to assess the potential impact of cytomegalovirus (CMV) infections in Wilms' tumor. RESULTS: T-cell receptor (TCR) complementarity determining region-3 (CDR3) amino acid sequences from Wilms' tumor specimens represented by the Therapeutically Applicable Research to Generate Effective Treatments dataset were compared with known anti-CMV TCR CDR3s, indicating that cases representing the anti-CMV TCR CDR3s had worse outcomes. Then, a chemical complementarity scoring approach for the Wilms' tumor, TCR CDR3s and a series of CMV antigens further indicated that cases representing a higher chemical complementarity to the CMV antigens had worse outcomes. CONCLUSION: Overall, we present a potentially novel method to assess CMV infections and identify patients who could benefit from therapies that address such infections.

RESUMEN

BACKGROUND: Over the past decade, several studies have shown that potential of artificial intelligence (AI) in dermatology. However, there has yet to be a systematic review evaluating the usage of AI specifically within the field of Mohs micrographic surgery (MMS). OBJECTIVE: In this review, we aimed to comprehensively evaluate the current state, efficacy, and future implications of AI when applied to MMS for the treatment of nonmelanoma skin cancers (NMSC). MATERIALS AND METHODS: A systematic review and meta-analysis was conducted following PRISMA guidelines across several databases, including PubMed/MEDLINE, Embase, and Cochrane libraries. A predefined protocol was registered in PROSPERO, with literature search involving specific keywords related to AI and Mohs surgery for NMSC. RESULTS: From 23 studies evaluated, our results find that AI shows promise as a prediction tool for precisely identifying NMSC in tissue sections during MMS. Furthermore, high AUC and concordance values were also found across the various usages of AI in MMS, including margin control, surgical recommendations, similarity metrics, and in the prediction of stage and construction complexity. CONCLUSION: The findings of this review suggest promising potential for AI to enhance the accuracy and efficiency of Mohs surgery, particularly for NMSC.

RESUMEN

The rise in cancer rates in Sub-Saharan Africa (SSA), combined with limited access to Western pharmaceuticals, has sparked growing adoption of traditional and complementary medicine (T&CM) for cancer treatment in the region. However, many challenges exist, including the lack of reliable evidence-based research on these products, scarcity of standardized documentation as part of cancer registries, limited physician expertise, and negative effects on mortality. Nonetheless, herbal medicines also present opportunities for further research, development, and stakeholder education, potentially benefiting the regional healthcare systems in SSA countries and global health as whole. Recent trends highlight the willingness of patients to use mobile-based applications that provide accurate information on herbal therapeutics, reflecting the increasing adoption of internet and smart/mobile phone services in SSA. To maximize the potential benefits of traditional and complementary medicine, it is necessary to bridge the trust gap between the public, local practitioners, and Western healthcare providers. Sustained funding and policy support are needed to complement these initiatives. Our preliminary survey hopes to inspire the community and policymakers to embrace innovative solutions, fostering a forward-looking approach to cancer care in SSA.

RESUMEN

BACKGROUND/AIM: Due to still unresolved questions regarding viruses as either a primary cause or a comorbidity in cancer, we examined a potential immune response to cytomegalovirus (CMV) in the renal cell carcinoma (RCC) setting using genomics and bioinformatics approaches. MATERIALS AND METHODS: Specifically, we assessed chemical complementarity scores (CSs) for solid tissue normal resident, T-cell receptor (TCR) complementarity determining region 3 (CDR3s) and CMV antigens and determined whether higher or lower CS groups were associated with a higher or lower survival probability. RESULTS: This was indeed the case, with all such analyses consistently indicating a lower overall and progression-free survival for the cases representing the higher TCR CDR3-CMV antigen chemical CSs. This basic result was obtained for two separate RCC datasets and multiple CMV antigens. CONCLUSION: The results raise the question, to what extent a systemic CMV infection may represent an important co-morbidity for RCC.
