    Extensive efforts have been dedicated to exploring the impact of tumor heterogeneity on cancer treatment at both histological and genetic levels. To accurately measure intra-tumoral heterogeneity, a non-invasive imaging technique, known as habitat imaging, was developed. The technique quantifies intra-tumoral heterogeneity by dividing complex tumors into distinct sub- regions, called habitats. This article reviews the following aspects of habitat imaging in cancer treatment, with a focus on radiotherapy: (1) Habitat imaging biomarkers for assessing tumor physiology; (2) Methods for habitat generation; (3) Efforts to combine radiomics, another imaging quantification method, with habitat imaging; (4) Technical challenges and potential solutions related to habitat imaging; (5) Pathological validation of habitat imaging and how it can be utilized to evaluate cancer treatment by predicting treatment response including survival rate, recurrence, and pathological response as well as ongoing open clinical trials.

    批准的抗癌药物通常由于其狭窄的治疗窗口而面临挑战。主要是因为系统毒性高和对肿瘤的选择性有限。前药是最初无活性的药物分子,旨在进行特定的化学修饰。这些修饰使药物无活性,直到它们在体内遇到特定条件或生物标志物。在这一点上,它们被转化为活性药物分子。这种深思熟虑的设计通过增强肿瘤特异性和最小化脱靶效应显著提高了抗癌药物递送的功效。前药设计的最新进展集中于将这些策略与脂质体等递送系统整合,胶束,和聚合物小体,以进一步提高靶向性并减少副作用。这篇综述概述了设计刺激响应性小分子前药的策略,专注于癌症治疗。强调它们的化学结构和控制药物释放的机制。通过提供全面的概述,我们的目标是强调这些革新癌症治疗方法的潜力.
    Approved anticancer drugs typically face challenges due to their narrow therapeutic window, primarily because of high systemic toxicity and limited selectivity for tumors. Prodrugs are initially inactive drug molecules designed to undergo specific chemical modifications. These modifications render the drugs inactive until they encounter specific conditions or biomarkers in vivo, at which point they are converted into active drug molecules. This thoughtful design significantly improves the efficacy of anticancer drug delivery by enhancing tumor specificity and minimizing off-target effects. Recent advancements in prodrug design have focused on integrating these strategies with delivery systems like liposomes, micelles, and polymerosomes to further improve targeting and reduce side effects. This review outlines strategies for designing stimuli-responsive small molecule prodrugs focused on cancer treatment, emphasizing their chemical structures and the mechanisms controlling drug release. By providing a comprehensive overview, we aim to highlight the potential of these innovative approaches to revolutionize cancer therapy.

    方法:我们刮了GoFundMe.com和GiveSendGo.com众筹平台,以开展参考蒂华纳CAM癌症诊所的活动,始于2022年1月1日至2023年2月28日。作者创建了一个编码框架,以确定在蒂华纳寻求CAM治疗的理由。要补充市场活动元数据,我们编码了受益人的癌症阶段,type,年龄,寻求特定治疗,受益人是否死了,性别,和种族。
    结果:患者在蒂华纳寻求CAM癌症治疗,因为(1)治疗提供了最大的疗效(29.9%);(2)国内提供的治疗不是治愈的(23.2%);(3)诊所治疗整个人,并解决了人的精神层面(20.1%);(4)治疗是无毒的,自然,或侵入性较小(18.2%);(5)诊所提供最新技术(8.5%)。运动筹集了5,275,268.37美元,大多数运动受益者是妇女(69.7%)或白人(71.1%)。
    结论:这些运动传播了关于CAM治疗可能疗效的有问题的错误信息,向蒂华纳的CAM诊所提供资金和代言,让许多活动家缺乏支付CAM治疗所需的资金,同时花费受益人和他们所爱的人的时间,隐私,和尊严。这项研究证实了蒂华纳,墨西哥,是CAM癌症治疗的一个非常受欢迎的目的地。
    BACKGROUND: Complementary and alternative (CAM) cancer treatment is often expensive and not covered by insurance. As a result, many people turn to crowdfunding to access this treatment.
    OBJECTIVE: The aim of this study is to identify the rationales of patients with cancer seeking CAM treatment abroad by looking specifically at crowdfunding campaigns to support CAM cancer treatment in Tijuana, Mexico.
    METHODS: We scraped the GoFundMe.com and GiveSendGo.com crowdfunding platforms for campaigns referencing CAM cancer clinics in Tijuana, initiated between January 1, 2022, and February 28, 2023. The authors created a coding framework to identify rationales for seeking CAM treatment in Tijuana. To supplement campaign metadata, we coded the beneficiary\'s cancer stage, type, age, specific treatment sought, whether the beneficiary died, gender, and race.
    RESULTS: Patients sought CAM cancer treatment in Tijuana because the (1) treatment offers the greatest efficacy (29.9%); (2) treatment offered domestically was not curative (23.2%); (3) the clinic treats the whole person, and addresses the spiritual dimension of the person (20.1%); (4) treatments are nontoxic, natural, or less invasive (18.2%); and (5) clinic offers the newest technology (8.5%). Campaigns raised US $5,275,268.37 and most campaign beneficiaries were women (69.7%) or White individuals (71.1%).
    CONCLUSIONS: These campaigns spread problematic misinformation about the likely efficacy of CAM treatments, funnel money and endorsements to CAM clinics in Tijuana, and leave many campaigners short of the money needed to pay for CAM treatments while costing beneficiaries and their loved one\'s time, privacy, and dignity. This study affirms that Tijuana, Mexico, is a very popular destination for CAM cancer treatment.

    癌症是世界上死亡率的主要贡献者。作为治疗选择的常规疗法是化疗,放疗和手术。然而,这些治疗方法在大多数情况下几乎没有细胞特异性。如今,在癌症治疗之前,进行了广泛的研究和调查以开发细胞特异性方法。其中一些是光动力疗法,热疗,免疫疗法,干细胞移植和靶向治疗。本文将对肿瘤基因治疗的发展进行综述。基因治疗的目的是纠正导致癌症的细胞过度增殖的特定突变基因。在修饰基因的方法上有很多探索。这种疗法的实施在其成功中起着重要作用。如果插入的基因找不到目标,治疗被认为是失败的。因此,载体是必需的,常用的载体是病毒,非病毒或合成,基于聚合物和基于脂质的载体。基因治疗在癌症治疗中的进展将集中在世界三大癌症病例上,即乳腺癌,肺癌和结肠癌。在乳腺癌中,讨论的疗法是CRISPR/Cas9,siRNA和基因沉默,而在结肠癌miRNA和自杀基因治疗以及肺癌中,替换抑癌基因,CRISPR/Cas9和miRNA。
    Cancer is the main contributor for mortality in the world. Conventional therapy that available as the treatment options are chemotherapy, radiotherapy and surgery. However, these treatments are hardly cell-specific most of the time. Nowadays, extensive research and investigations are made to develop cell-specific approaches prior to cancer treatment. Some of them are photodynamic therapy, hyperthermia, immunotherapy, stem cell transplantation and targeted therapy. This review article will be focusing on the development of gene therapy in cancer. The objective of gene therapy is to correct specific mutant genes causing the excessive proliferation of the cell that leads to cancer. There are lots of explorations in the approach to modify the gene. The delivery of this therapy plays a big role in its success. If the inserted gene does not find its way to the target, the therapy is considered a failure. Hence, vectors are needed and the common vectors used are viral, non viral or synthetic, polymer based and lipid based vectors. The advancement of gene therapy in cancer treatment will be focussing on the top three cancer cases in the world which are breast, lung and colon cancer. In breast cancer, the discussed therapy are CRISPR/Cas9, siRNA and gene silencing whereas in colon cancer miRNA and suicide gene therapy and in lung cancer, replacement of tumor suppressor gene, CRISPR/Cas9 and miRNA.

    醛缩酶,特别是ALDOA,ALDOB,和ALDOC,在癌症的发展和进展中起着至关重要的作用。虽然醛缩酶家族主要以参与糖酵解途径而闻名,这些酶还通过不同的信号通路,如Wnt/β-catenin,EGFR/MAPK,Akt,和HIF-1α。近年来,这引起了越来越多的关注,并揭示了这种酶的其他方面。靶向醛缩酶的潜在治疗策略包括使用siRNA,抑制剂如萘酚AS-E磷酸酯和TX-2098,以及天然化合物如HDPS-4II和L-肌肽。此外,来自ALDOA的抗癌肽,像P04一样,可能会增加癌细胞对化疗的敏感性。醛缩酶还通过不同的方法影响癌症的耐药性,使它们成为良好的治疗目标。在这次审查中,我们广泛探索醛缩酶在各种癌症增殖中的作用,入侵,迁移,和耐药性;我们还显着探索考虑醛缩酶功能的可能治疗方法。
    Aldolase enzymes, particularly ALDOA, ALDOB, and ALDOC, play a crucial role in the development and progression of cancer. While the aldolase family is mainly known for its involvement in the glycolysis pathway, these enzymes also have various pathological and physiological functions through distinct signaling pathways such as Wnt/β-catenin, EGFR/MAPK, Akt, and HIF-1α. This has garnered increased attention in recent years and shed light on other sides of this enzyme. Potential therapeutic strategies targeting aldolases include using siRNA, inhibitors like naphthol AS-E phosphate and TX-2098, and natural compounds such as HDPS-4II and L-carnosine. Additionally, anticancer peptides derived from ALDOA, like P04, can potentially increase cancer cells\' sensitivity to chemotherapy. Aldolases also affect cancer drug resistance by different approaches, making them good therapeutic targets. In this review, we extensively explore the role of aldolase enzymes in various types of cancers in proliferation, invasion, migration, and drug resistance; we also significantly explore the possible treatment considering aldolase function.

    目前,由于生活质量低,癌症患者的数量一直在增加。出于这个原因,用于治疗癌症的疗法已经得到了专家的很多考虑。许多抗癌药物已被用于治疗癌症患者。然而,立即使用抗癌药物会导致患者不愉快的副作用,并且对应用这些治疗有许多限制。许多聚合物,如纤维素,壳聚糖,聚乙烯醇(PVA),聚丙烯腈(PAN),多肽和聚羟基链烷酸酯具有良好的治疗癌症的性能,但是通过同轴静电纺丝技术生产的基于纳米纤维的靶标和受控药物递送系统具有非凡的性能,例如良好的机械特性,一个很好的释放配置文件,高表面积,和高海绵状和无害的,生物可再生,生物友好,高度可降解,并且可以非常方便地以工业规模生产。因此,通过同轴静电纺丝生产的纳米纤维可以设计为靶向特定的癌细胞或组织。通过改变纳米纤维的组成和性能,研究人员可以控制治疗剂的释放动力学,并增强其在肿瘤部位的积累,同时将全身毒性降至最低。同轴电纺纳米纤维的核-壳结构允许治疗剂随时间的受控和持续释放。这种受控释放曲线可以通过在肿瘤微环境内维持治疗药物浓度延长的时间来提高癌症治疗的功效。
    Currently, the number of patients with cancer is expanding consistently because of a low quality of life. For this reason, the therapies used to treat cancer have received a lot of consideration from specialists. Numerous anticancer medications have been utilized to treat patients with cancer. However, the immediate utilization of anticancer medicines leads to unpleasant side effects for patients and there are many restrictions to applying these treatments. A number of polymers like cellulose, chitosan, Polyvinyl Alcohol (PVA), Polyacrylonitrile (PAN), peptides and Poly (hydroxy alkanoate) have good properties for the treatment of cancer, but the nanofibers-based target and controlled drug delivery system produced by the co-axial electrospinning technique have extraordinary properties like favorable mechanical characteristics, an excellent release profile, a high surface area, and a high sponginess and are harmless, bio-renewable, biofriendly, highly degradable, and can be produced very conveniently on an industrial scale. Thus, nanofibers produced through coaxial electrospinning can be designed to target specific cancer cells or tissues. By modifying the composition and properties of the nanofibers, researchers can control the release kinetics of the therapeutic agent and enhance its accumulation at the tumor site while minimizing systemic toxicity. The core-shell structure of coaxial electrospun nanofibers allows for a controlled and sustained release of therapeutic agents over time. This controlled release profile can improve the efficacy of cancer treatment by maintaining therapeutic drug concentrations within the tumor microenvironment for an extended period.
