Application of dendritic cell extracellular vesicles as a valid nanoparticle platform for cancer therapies: a narrative review.

The prevalence of cancers has actually increased during the last few decades, affecting almost all human societies. Despite progress in therapeutic protocols, cancer is still the main cause of global human mortality. Although the advancement of modern immunotherapeutic approaches can increase the survival rate of cancer patients, new modalities are essential for improved therapeutic outcomes. Extracellular vesicles (EVs) are nanosized particles and are used for cell-free approaches instead of direct whole cell-based administration. It has been thought that EVs can reduce the risks and side eff

New clinical research strategies in thoracic oncology: clinical trial design, adaptive, basket and umbrella trials, new end-points and new evaluations of response.

In the genomics era, our main goal should be to identify large and meaningful differences in small, molecularly selected groups of patients. Classical phase I, II and III models for drug development require large resources, limiting the number of experimental agents that can be tested and making the evaluation of targeted agents inefficient. There is an urgent need to streamline the development of new compounds, with the aim of identifying "trials designed to learn", which could lead to subsequent "trials designed to conclude". Basket trials are often viewed as parallel phase II trials within

Predicting tumour response.

Response prediction is an important emerging concept in oncologic imaging, with tailored, individualized treatment regimens increasingly becoming the standard of care. This review aims to define tumour response and illustrate the ways in which imaging techniques can demonstrate tumour biological characteristics that provide information on the likely benefit to be received by treatment. Two imaging approaches are described: identification of therapeutic targets and depiction of the treatment-resistant phenotype. The former approach is exemplified by the use of radionuclide imaging to confirm ta

Long-term stabilization of metastatic melanoma with sodium dichloroacetate.

Sodium dichloroacetate (DCA) has been studied as a metabolic cancer therapy since 2007, based on a publication from Bonnet et al demonstrating that DCA can induce apoptosis (programmed cell death) in human breast, lung and brain cancer cells. Classically, the response of cancer to a medical therapy in human research is measured by Response Evaluation Criterial for Solid Tumours definitions, which define "response" by the degree of tumour reduction, or tumour disappearance on imaging, however disease stabilization is also a beneficial clinical outcome. It has been shown that DCA can function as

Navigating Stomatologic Complications Secondary to Antineoplastic Agents-A Comprehensive Review.

This review systematically examines the oral complications associated with conventional and novel anti-cancer therapies. It highlights that while molecularly targeted agents including monoclonal antibodies targeting the vascular endothelial growth factor and its receptor, the epidermal growth factor receptor, tyrosine kinase inhibitors, and immune checkpoint inhibitors tend to exhibit a lower overall toxicity profile compared to traditional cytotoxic chemotherapeutics, they are nonetheless linked to significant oral adverse events. These complications encompass inflammatory mucosal reactions k

Cancer Chemoprevention: A Strategic Approach Using Phytochemicals.

Cancer chemoprevention approaches are aimed at preventing, delaying, or suppressing tumor incidence using synthetic or natural bioactive agents. Mechanistically, chemopreventive agents also aid in mitigating cancer development, either by impeding DNA damage or by blocking the division of premalignant cells with DNA damage. Several pre-clinical studies have substantiated the benefits of using various dietary components as chemopreventives in cancer therapy. The incessant rise in the number of cancer cases globally is an issue of major concern. The excessive toxicity and chemoresistance associat

An Overview of Bortezomib-Induced Neurotoxicity.

The boronic acid dipeptide bortezomib, able to induce tumor cell death by degradation of key proteins, is the first proteasome inhibitor drug to enter clinical practice. It is employed as first-line treatment in relapsed or resistant multiple myeloma (MM) patients. However, bortezomib often induces a dose-limiting toxicity in the form of painful sensory neuropathy, which can mainly be reduced by subcutaneous administration or dose modification. In this review we focus on the current understanding of the pathophysiological mechanisms of bortezomib-induced neuropathy to allow further studies in

From Nanoparticles to Cancer Nanomedicine: Old Problems with New Solutions.

Anticancer nanomedicines have been studied over 30 years, but fewer than 10 formulations have been approved for clinical therapy today. Despite abundant options of anticancer drugs, it remains challenging to have agents specifically target cancer cells while reducing collateral toxicity to healthy tissue. Nanocompartments that can be selective toward points deeply within malignant tissues are a promising concept, but the heterogeneity of tumor tissue, inefficiency of cargo loading and releasing, and low uniformity of manufacture required from preclinical to commercialization are major obstacle

Effects of Physical Cues on Stem Cell-Derived Extracellular Vesicles toward Neuropathy Applications.

The peripheral nervous system undergoes sufficient stress when affected by diabetic conditions, chemotherapeutic drugs, and personal injury. Consequently, peripheral neuropathy arises as the most common complication, leading to debilitating symptoms that significantly alter the quality and way of life. The resulting chronic pain requires a treatment approach that does not simply mask the accompanying symptoms but provides the necessary external environment and neurotrophic factors that will effectively facilitate nerve regeneration. Under normal conditions, the peripheral nervous system self-r

Cancer of Unknown Primary: Challenges and Progress in Clinical Management.

Distant metastases are the main cause of cancer-related deaths in patients with advanced tumors. A standard diagnostic workup usually contains the identification of the tissue-of-origin of metastatic tumors, although under certain circumstances, it remains elusive. This disease setting is defined as cancer of unknown primary (CUP). Accounting for approximately 3-5% of all cancer diagnoses, CUPs are characterized by an aggressive clinical behavior and represent a real therapeutic challenge. The lack of determination of a tissue of origin precludes CUP patients from specific evidence-based thera

Targeting the JAK2/STAT3 Pathway-Can We Compare It to the Two Faces of the God Janus?

Muscle cachexia is one of the most critical unmet medical needs. Identifying the molecular background of cancer-induced muscle loss revealed a promising possibility of new therapeutic targets and new drug development. In this review, we will define the signal transducer and activator of transcription 3 (STAT3) protein's role in the tumor formation process and summarize the role of STAT3 in skeletal muscle cachexia. Finally, we will discuss a vast therapeutic potential for the STAT3-inhibiting single-agent treatment innovation that, as the desired outcome, could block tumor growth and generally

A year in pharmacology: new drugs approved by the US Food and Drug Administration in 2021.

The second year of the COVID-19 pandemic had no adverse effect on the number of new drug approvals by the US Food and Drug Administration (FDA). Quite the contrary, with a total of 50 new drugs, 2021 belongs to the most successful FDA years. We assign these new drugs to one of three levels of innovation: (1) first drug against a condition ("first-in-indication"), (2) first drug using a novel molecular mechanism ("first-in-class"), and (3) "next-in-class", i.e., a drug using an already exploited molecular mechanism. We identify 21 first-in-class, 28 next-in-class, and only one first-in-indicati

Anti-Cancer Potential of Cannabinoids, Terpenes, and Flavonoids Present in Cannabis.

In recent years, and even more since its legalization in several jurisdictions, cannabis and the endocannabinoid system have received an increasing amount of interest related to their potential exploitation in clinical settings. Cannabinoids have been suggested and shown to be effective in the treatment of various conditions. In cancer, the endocannabinoid system is altered in numerous types of tumours and can relate to cancer prognosis and disease outcome. Additionally, cannabinoids display anticancer effects in several models by suppressing the proliferation, migration and/or invasion of can

Exosomes in oncofertility: emerging roles in chemotherapy-induced reproductive damage and fertility preservation.

ABSTRACT: Oncofertility has emerged as a critical interdisciplinary field addressing the reproductive challenges faced by cancer patients, particularly those undergoing chemotherapy. While chemotherapeutic agents remain indispensable in cancer therapy, their gonadotoxic effects frequently result in diminished ovarian reserve, impaired spermatogenesis, and long-term infertility. Exosomes - small extracellular vesicles enriched with nucleic acids, proteins, and lipids - are increasingly recognized as key mediators of intercellular communication in both pathological and regenerative contexts.
