Antibody-drug conjugates in cancer therapy: mechanisms and clinical studies.

Antibody-drug conjugates (ADCs) consist of monoclonal antibodies that target tumor cells and cytotoxic drugs linked through linkers. By leveraging antibodies' targeting properties, ADCs deliver cytotoxic drugs into tumor cells via endocytosis after identifying the tumor antigen. This precise method aims to kill tumor cells selectively while minimizing harm to normal cells, offering safe and effective therapeutic benefits. Recent years have seen significant progress in antitumor treatment with ADC development, providing patients with new and potent treatment options. With over 300 ADCs explored

Chemotherapy for small cell lung cancer: a comprehensive review.

Combination chemotherapy is the current strategy of choice for treatment of small cell lung cancer (SCLC). Platinum containing combination regimens are superior to non-platinum regimens in limited stage-SCLC and possibly also in extensive stage-SCLC as first and second-line treatments. The addition of ifosfamide to platinum containing regimens may improve the outcome but at the price of increased toxicity. Suboptimal doses of chemotherapy result in inferior survival. Early intensified, accelerated and high-dose chemotherapy gave conflicting results and is not considered a standard option outsi

PurposeThis review provides an update on the current clinical, epidemiological and pathophysiological evidence alongside the diagnostic, prevention and treatment approach to chemotherapy-induced peripheral neuropathy (CIPN).FindingsThe incidence of cancer and long-term survival after treatment is increasing. CIPN affects sensory, motor and autonomic nerves and is one of the most common adverse events caused by chemotherapeutic agents, which in severe cases leads to dose reduction or treatment cessation, with increased mortality. The primary classes of chemotherapeutic agents associated with CI

Antitumoral Effects of Tricyclic Antidepressants: Beyond Neuropathic Pain Treatment.

Growing evidence shows that nerves play an active role in cancer development and progression by altering crucial molecular pathways and cell functions. Conversely, the use of neurotropic drugs, such as tricyclic antidepressants (TCAs), may modulate these molecular signals with a therapeutic purpose based on a direct antitumoral effect and beyond the TCA use to treat neuropathic pain in oncology patients. In this review, we discuss the TCAs' safety and their central effects against neuropathic pain in cancer, and the antitumoral effects of TCAs in in vitro and preclinical studies, as well as in

Looking for the Holy Grail-Drug Candidates for Glioblastoma Multiforme Chemotherapy.

Glioblastoma multiforme (GBM) is the deadliest and the most heterogeneous brain cancer. The median survival time of GBM patients is approximately 8 to 15 months after initial diagnosis. GBM development is determined by numerous signaling pathways and is considered one of the most challenging and complicated-to-treat cancer types. Standard GBM therapy consist of surgery followed by radiotherapy or chemotherapy, and combined treatment. Current standard of care (SOC) does not offer a significant chance for GBM patients to combat cancer, and the selection of available drugs is limited. For almost

Crosstalk of thioredoxin system and programmed cell death: from pathophysiology to novel therapy.

The thioredoxin (Trx) system, an integral component of cellular redox regulation, preserves protein dithiol-disulfide equilibrium through its conserved Cys-Gly-Pro-Cys active site and is involved in key cellular functions, including cell proliferation, apoptosis, and signal transduction. In cancer biology, the thioredoxin system plays dual roles: overexpression can suppress oxidative stress and promote tumor growth, whereas dysfunction can trigger programmed cell death (PCD). However, a critical area for future research is to delineate how Trx modulates the intricate networks of PCD, and to id

Stochasticity of anticancer mechanisms underlying clinical effectiveness of vorinostat.

The Food and Drug Administration (FDA) has approved vorinostat, also called Zolinza®, for its effectiveness in fighting cancer. This drug is a suberoyl-anilide hydroxamic acid belonging to the class of histone deacetylase inhibitors (HDACis). Its HDAC inhibitory potential allows it to accumulate acetylated histones. This, in turn, can restore normal gene expression in cancer cells and activate multiple signaling pathways. Experiments have proven that vorinostat induces histone acetylation and cytotoxicity in many cancer cell lines, increases the level of p21 cell cycle proteins, and enhances p

Serum neurofilament light chain (sNFL) as a predictive biomarker for Chemotherapy-induced peripheral neurotoxicity (CIPN): consideration of current evidence, validation steps, and barriers to CIPN biomarker implementation in clinical practice-a narrative review.

PurposeSeveral anticancer drugs can cause chemotherapy-induced peripheral neurotoxicity (CIPN) in approximately 70% of patients; of these, 30% continue to have chronic symptoms hampering quality of life. As more people live with and beyond cancer therapy, it is becoming increasingly important for clinicians to assess those at higher risk of CIPN and provide care for managing CIPN severity. Biomarkers could be appropriate in this regard. However, an initial step towards biomarker-informed care is to advance scientific knowledge regarding the potential of current biomarkers such as neurofilament

Molecular targeted therapy for anticancer treatment.

Since the initial clinical approval in the late 1990s and remarkable anticancer effects for certain types of cancer, molecular targeted therapy utilizing small molecule agents or therapeutic monoclonal antibodies acting as signal transduction inhibitors has served as a fundamental backbone in precision medicine for cancer treatment. These approaches are now used clinically as first-line therapy for various types of human cancers. Compared to conventional chemotherapy, targeted therapeutic agents have efficient anticancer effects with fewer side effects. However, the emergence of drug resistanc

Drug repurposing in KRAS G12C-mutant NSCLC: a focus on resistance mechanisms and clinical strategies.

KRAS G12C-mutant non-small cell lung cancer (NSCLC) has transitioned from a therapeutically problematic disease to a precision-targetable cancer, anchored by the landmark approvals of sotorasib and adagrasib. Yet despite these advances, responses remain limited in duration and multiple mechanisms of rapid adaptive resistance emerge under inhibitor pressure. These resistance mechanisms define a therapeutic vulnerability map that can be addressed by repurposing approved agents with established safety profiles. This review emphasises the current understanding of KRAS G12C biology, integrates upda

Therapies and nanotherapies for cervical cancer (Review).

Cervical cancer (CC) is a major global health concern, ranking fourth worldwide in mortality, due to its high death rate and strong link to persistent high-risk human papillomavirus infections, which drive cancer progression through cellular dysregulation. Conventional therapies used in the treatment of CC have significant disadvantages, such as adverse side effects that affect the quality of life of patients. These side effects may include nausea, vomiting, fatigue, hair loss, fertility problems, damage to nearby organs and systemic toxicity. To address these challenges, there has been an inc

Roles of circadian clocks in cancer pathogenesis and treatment.

Circadian clocks are ubiquitous timing mechanisms that generate approximately 24-h rhythms in cellular and bodily functions across nearly all living species. These internal clock systems enable living organisms to anticipate and respond to daily changes in their environment in a timely manner, optimizing temporal physiology and behaviors. Dysregulation of circadian rhythms by genetic and environmental risk factors increases susceptibility to multiple diseases, particularly cancers. A growing number of studies have revealed dynamic crosstalk between circadian clocks and cancer pathways, providi

Bispecific antibodies in the treatment of epithelial ovarian, endometrial, and cervical cancer: an overview of current applications, challenges, and emerging opportunities.

Gynecological cancer remains one of the leading causes of mortality worldwide. Recent advances in genomic and molecular sequencing have significantly enhanced our understanding of the biological pathways that drive tumor progression and resistance to therapy. Targeted therapies, including monoclonal antibodies (mAbs), have revolutionized cancer treatment by selectively interfering with oncogenic proteins expressed on cancer cells. However, the long-term clinical benefit is often limited due to the emergence of drug resistance, frequently mediated by compensatory signaling pathways or immune es

In vitro models of breast cancer bone metastasis: analyzing drug resistance through the lens of the microenvironment.

Even though breast cancers usually have a good outcome compared to other tumors, the cancer can progress and create metastases in different parts of the organism, the bone being a predilection locus. These metastases are usually the cause of death, as they are mostly resistant to treatments. This resistance can be caused by intrinsic properties of the tumor, such as its heterogeneity, but it can also be due to the protective role of the microenvironment. By activating signaling pathways protecting cancer cells when exposed to chemotherapy, contributing to their ability to reach dormancy, or ev

Managing treatment-related peripheral neuropathy in patients with multiple myeloma.

Peripheral neuropathy is one of the most important complications of multiple myeloma treatment. Neurological damage can be observed at the onset of the disease, due to the effect of monoclonal protein or radicular compression, but more often is treatment related. Vinca alkaloids in the past era, and more recently, thalidomide and bortezomib are mainly responsible. Degeneration of dorsal root ganglion is common, prevalently related to angiogenesis inhibition and cytokine modulation in the case of thalidomide and inhibition of the ubiquitin proteasome system in the case of bortezomib.
