Proteomic alterations in ovarian cancer-Predicting residual disease status using artificial intelligence and SHAP-based biomarker interpretation.

IntroductionHigh-grade serous ovarian cancer (HGSOC) is the most aggressive and prevalent subtype of ovarian Treatment outcomes are significantly influenced by residual disease status following neoadjuvant chemotherapy (NACT). Predicting residual disease before surgery can improve patient stratification and personalized treatment strategies.MethodsThis study analyzed pre-NACT proteomic data from 20 HGSOC patients treated with NACT. Patients were categorized into two groups based on surgical outcomes: no residual disease (R0, n = 14) and suboptimal residual disease (R1, n = 6). From an initial

Reframing small cell lung cancer: therapeutic lessons from hematologic malignancies.

Small cell lung cancer (SCLC) remains one of the most aggressive malignancies, characterized by rapid proliferation, early metastatic dissemination, and poor long-term survival despite initial sensitivity to therapy. SCLC shares several biologic and therapeutic principles with hematologic malignancies, including lineage state dependence, adaptive resistance through non-genetic plasticity, and emerging susceptibility to antigen-directed immune therapies. Reframing SCLC through this lens provides a conceptual framework for understanding treatment failure and identifying new therapeutic strategie

Clinical outcomes of chemotherapy in cancer patients with different ethnicities.

BackgroundChoosing the most effective chemotherapeutic agent with safest side effect profile is a common challenge in cancer treatment. Although there are standardized chemotherapy protocols in place, protocol changes made after extensive clinical trials demonstrate significant improvement in the efficacy and tolerability of certain drugs. The pharmacokinetics, pharmacodynamics, and tolerance of anti-cancer medications are all highly individualized. A driving force behind these differences lies within a person's genetic makeup.Recent findingsPharmacogenomics, the study of how an individual's g

Unveiling the Synergistic Potential: Bispecific Antibodies in Conjunction with Chemotherapy for Advanced Non-Small-Cell Lung Cancer Treatment.

Despite advancements in targeted therapies and immunotherapies, many patients still rely on chemotherapy, highlighting the need for innovative treatment strategies. Bispecific antibodies (bsAbs), which feature two distinct binding sites capable of targeting different antigens, have emerged as a promising therapeutic approach, particularly in combination with chemotherapy. This review explores the scientific evolution and clinical applica

The anti-PD-1 era of cervical cancer: achievement, opportunity, and challenge.

Cervical cancer is one of the three major female gynecological malignancies, becoming a major global health challenge. Although about 90% of early-stage patients can be cured by surgery, advanced-stage patients still need new treatment methods to improve their efficacy, especially for those with recurrence and metastasis tumors. Anti-PD-1 is currently the most widely used immune checkpoint inhibitor, which has revolutionized cancer therapy for different types of cancer. Pembrolizumab has been approved for second-line treatment of R/M CC but has a modest overall response rate of about 15%. Ther

The functional role of long noncoding RNA in resistance to anticancer treatment.

Chemotherapy is one of the fundamental methods of cancer treatment. However, drug resistance remains the main cause of clinical treatment failure. We comprehensively review the newly identified roles of long noncoding RNAs (lncRNAs) in oncobiology that are associated with drug resistance. The expression of lncRNAs is tissue-specific and often dysregulated in human cancers. Accumulating evidence suggests that lncRNAs are involved in chemoresistance of cancer cells. The main lncRNA-driven mechanisms of chemoresistance include regulation of drug efflux, DNA damage repair, cell cycle, apoptosis, e

An overview of antibody-drug conjugates in oncological practice.

Antibody-drug conjugates (ADCs) are designed to manipulate the toxic efficacy of specific chemotherapeutic compounds, employing the high affinity of antibody-mediated delivery so as to drive them selectively to target cancer cells. These immunoconjugates encompass the general tendency towards precision medicine and avert the systemic toxicities of conventional chemotherapy, accomplishing an improved therapeutic index. Cumulative experience acquired from first-generation ADCs offers new perspectives to these promising therapeutic modalities for various hematological and solid cancers and propel

Mechanisms of spinal glial activation in chemotherapy-induced peripheral neuropathy: Focus on microglia and astrocytes.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication in patients with malignant tumors during chemotherapy. The pathological mechanisms of CIPN remain unclear, and effective preventive and therapeutic strategies are still lacking, posing a major challenge in clinical practice. Aberrant activation of spinal glial cells, particularly microglia and astrocytes, is a key pathological hallmark of CIPN. Evidence from multiple animal models supports a causal link between glial activation and CIPN, suggesting that glial cells may serve as potential therapeutic targets. However, ow

Adverse events of antibody-drug conjugates on the ocular surface in cancer therapy.

Antibody-drug conjugates consist of a monoclonal antibody attached to a cytotoxic therapeutic molecule by a connector. This association allows a highly specific therapy, which increases their effectiveness and decreases their potential toxicity. This new therapy emerged approximately 20 years ago; since then, numerous combinations have appeared in the field of treatment-related neoplasms as an alternative for patients who do not achieve good results with conventional treatment options. Adverse effects of these drugs on the ocular surface are frequent and varied. Their prevalence ranges from 20

Mitochondrial Genetic and Epigenetic Regulations in Cancer: Therapeutic Potential.

Mitochondria are dynamic organelles managing crucial processes of cellular metabolism and bioenergetics. Enabling rapid cellular adaptation to altered endogenous and exogenous environments, mitochondria play an important role in many pathophysiological states, including cancer. Being under the control of mitochondrial and nuclear DNA (mtDNA and nDNA), mitochondria adjust their activity and biogenesis to cell demands. In cancer, numerous mutations in mtDNA have been detected, which do not inactivate mitochondrial functions but rather alter energy metabolism to support cancer cell growth. Increa

Новое применение XPO1 для лечения миэлофиброза.

Myelofibrosis (MF) — новообразование, характеризующееся конституционными симптомами, прогрессивными цитопентиями и селеногамели. В основе патобологии MF лежит активация мутации на пути JAK/STAT и регулирование цитокинового костного мозга. Хотя многие ингибиторы JAK в настоящее время официально утверждены и обеспечивают значительное улучшение симптомов, эти агенты не имеют курса на изменение потенциала. Кроме того, результаты являются неудовлетворительными для пациентов, которые не справляются с ингибиторами JAK, что подчеркивает необходимость применения новых методов лечения, основанных на исп

Epigenetics-targeted drugs: current paradigms and future challenges.

Epigenetics governs a chromatin state regulatory system through five key mechanisms: DNA modification, histone modification, RNA modification, chromatin remodeling, and non-coding RNA regulation. These mechanisms and their associated enzymes convey genetic information independently of DNA base sequences, playing essential roles in organismal development and homeostasis. Conversely, disruptions in epigenetic landscapes critically influence the pathogenesis of various human diseases. This understanding has laid a robust theoretical groundwork for developing drugs that target epigenetics-modifyin

Nuclear-Cytoplasmic Axis in Cancer: From Protein Mislocalization to Anticancer Drug Resistance.

Nucleocytoplasmic transport (NCT) regulates the spatial distribution of proteins and RNA between the nucleus and cytoplasm. NCT dysregulation can mislocalize tumor suppressors, DNA-repair factors, transcription factors, and drug targets in cancer. In this review, we conceptualize NCT-dependent protein mislocalization as a spatial regulatory framework for anticancer drug resistance, rather than as a catalogue of transport components. We systematically discuss how nuclear pore complex (NPC) remodeling, transport-receptor imbalance, post-translational modification (PTM)-regulated cargo routing, s

Restoring the Immunity in the Tumor Microenvironment: Insights into Immunogenic Cell Death in Onco-Therapies.

Immunogenic cell death (ICD) elicited by cancer therapy reshapes the tumor immune microenvironment. A long-term adaptative immune response can be initiated by modulating cell death by therapeutic approaches. Here, the major hallmarks of ICD, endoplasmic reticulum (ER) stress, and damage-associated molecular patterns (DAMPs) are correlated with ICD inducers used in clinical practice to enhance antitumoral activity by suppressing tumor immune evasion. Approaches to monitoring the ICD triggered by antitumoral therapeutics in the tumor microenvironment (TME) and novel perspective in this immune sy

PD-1 Pathway Inhibitors: Immuno-Oncology Agents for Restoring Antitumor Immune Responses.

Immune checkpoint inhibitors are designed to restore a patient's own antitumor immune response that has been suppressed during tumor development. The first monoclonal antibodies against the immune checkpoint programmed death 1 (PD-1) receptor, nivolumab and pembrolizumab, are now approved for clinical use. Both agents are indicated for the treatment of advanced melanoma, as well as for the treatment of metastatic non-small cell lung cancer (NSCLC). Nivolumab is also approved for the treatment of advanced renal cell carcinoma. In patients with melanoma, these agents result in objective response
