Actinium-225 targeted alpha particle therapy for prostate cancer.

Targeted alpha particle therapy (TAT) has emerged as a promising strategy for the treatment of prostate cancer (PCa). Actinium-225 (225Ac), a potent alpha-emitting radionuclide, may be incorporated into targeting vectors, causing robust and in some cases sustained antitumor responses. The development of radiolabeling techniques involving EDTA, DOTA, DOTPA, and Macropa chelators has laid the groundwork for advancements in this field. At the forefront of clinical trials with 225Ac in PCa are PSMA-targeted TAT agents, notably [225Ac]Ac-PSMA-617, [225Ac]Ac-PSMA-I&T and [225Ac]Ac-J591. Ongoing inve

Reactive Oxygen Species Bridge the Gap between Chronic Inflammation and Tumor Development.

According to numerous animal studies, adverse environmental stimuli, including physical, chemical, and biological factors, can cause low-grade chronic inflammation and subsequent tumor development. Human epidemiological evidence has confirmed the close relationship between chronic inflammation and tumorigenesis. However, the mechanisms driving the development of persistent inflammation toward tumorigenesis remain unclear. In this study, we assess the potential role of reactive oxygen species (ROS) and associated mechanisms in modulating inflammation-induced tumorigenesis. Recent reports have e

Primary and Acquired Resistance to Immunotherapy in Lung Cancer: Unveiling the Mechanisms Underlying of Immune Checkpoint Blockade Therapy.

After several decades without maintained responses or long-term survival of patients with lung cancer, novel therapies have emerged as a hopeful milestone in this research field. The appearance of immunotherapy, especially immune checkpoint inhibitors, has improved both the overall survival and quality of life of patients, many of whom are diagnosed late when classical treatments are ineffective. Despite these unprecedented results, a high percentage of patients do not respond initially to treatment or relapse after a period of response. This is due to resistance mechanisms, which require unde

A Comprehensive Review of Modern Cancer Therapies Utilizing Oncolytic Viruses.

Oncolytic viruses (OVs) are gaining traction as advanced tools in cancer therapy. They are distinguished by their ability to destroy malignant cells while sparing normal tissue specifically. In addition to their direct tumor-lysing properties, an essential benefit of oncolytic virus therapy is its capacity to activate both the innate and adaptive immune systems. To enhance these therapeutic actions, many OVs have been genetically engineered to encode immune-modulating factors that reestablish or strengthen antitumor immune responses. Recent studies show that combining OVs with other forms of i

Hedgehog signaling in tissue homeostasis, cancers, and targeted therapies.

The past decade has seen significant advances in our understanding of Hedgehog (HH) signaling pathway in various biological events. HH signaling pathway exerts its biological effects through a complex signaling cascade involved with primary cilium.

Background: In the last decade, a surge of advancements in and approvals of immunotherapies has revolutionized the treatment of non-small-cell lung cancer (NSCLC). Even as an increasing number of immune checkpoint inhibitors and antibody-drug conjugates gained FDA approval for the remarkable response and durable remission they imparted to some patients, persistent challenges of primary and acquired resistance, imperfect predictive biomarkers, and toxicity remain. Methods: This review identifies and summarizes the most significant emerging clinical data being reported for immunotherapies in NSC

Rare Diseases of the Orbit.

This article provides an overview of rare orbital diseases. Congenital malformations, inflammatory diseases, benign and malignant neoplasias are described. Although it represents a relatively small area of the body the orbit contains multiple different tissues. Therefore, a great variety of diseases can be found within the orbital space. That is the reason, why both the completeness and the level of detail in the description of particular diseases must be somewhat limited. Nevertheless, clinical manifestations, important aspects of diagnosis, treatment strategies, and, when specific data are a

Circulating Tumour Cells (CTCs) in NSCLC: From Prognosis to Therapy Design.

Designing optimal (neo)adjuvant therapy is a crucial aspect of the treatment of non-small-cell lung carcinoma (NSCLC). Standard methods of chemotherapy, radiotherapy, and immunotherapy represent effective strategies for treatment. However, in some cases with high metastatic activity and high levels of circulating tumour cells (CTCs), the efficacy of standard treatment methods is insufficient and results in treatment failure and reduced patient survival. CTCs are seen not only as an isolated phenomenon but also a key inherent part of the formation of metastasis and a key factor in cancer death.

Landscape of T-cell engagers in solid tumors.

T-cell engagers (TCEs) are a diverse class of bispecific and multispecific molecules that co-bind CD3 on T cells and tumor-associated antigens to form an immune synapse and induce targeted T-cell-mediated cytotoxicity. While TCEs have demonstrated remarkable efficacy in hematologic malignancies, translation into solid tumors has been more challenging. Recent advances seen with tebentafusp in metastatic uveal melanoma and tarlatamab in small-cell lung cancer have validated the approach and driven a rapidly expanding pipeline targeting other tumor associated antigens such as STEAP1, MUC16, and P

Antibody-Drug Conjugates in Contemporary Oncology: A Clinical Perspective on Dose Optimization, Sequencing, and Combination Strategies.

Antibody-drug conjugates (ADCs) have matured from a technically challenging concept into an established therapeutic platform across hematologic and solid malignancies. By linking a monoclonal antibody to a potent cytotoxic payload, ADCs seek to increase tumor-directed drug delivery while limiting systemic exposure; however, clinical performance depends on much more than target expression. Target accessibility, antigen density and heterogeneity, internalization, intracellular trafficking, linker stability, payload properties, drug-to-antibody ratio, bystander effect, tumor penetration, and host
