Targeted radioligand therapy (TRT) is an emerging theranostic modality in oncology. While well established in neuroendocrine and prostate cancers, its role in small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) remains investigational. This systematic review summarizes current evidence evaluating TRT in lung cancer. A Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA)-guided systematic review of PubMed, Embase, and Scopus (2000-November 2025) was conducted. Original studies evaluating TRT in SCLC or NSCLC were included. Primary outcomes were tumor response, disease-control rate, and treatment-related toxicity. Secondary outcomes included progression-free survival, overall survival, and dosimetry. Risk of bias was assessed using the Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) tool. From 2,453 records, 15 studies were included, reporting 358 lung cancer patients, of whom 105 received TRT. Disease-control rates reached up to 78% in mixed NSCLC/SCLC cohorts. In SCLC, somatostatin receptor-targeted peptide receptor radionuclide therapy demonstrated heterogeneous disease control (0-50%), with [177Lu]Lu-labeled agents showing more favorable outcomes than [90Y]Y-based therapy. The most favorable outcomes were a median progression-free survival of 11.9 months and an overall survival of 16 months in responders. In NSCLC, fibroblast activation protein (FAP)-targeted agents such as [177Lu]Lu-FAP-2286 demonstrated partial metabolic responses, including a 44.4% response rate and 78% disease control in a mixed cohort. Severe toxicities were infrequent. TRT is a promising but experimental option for advanced lung cancer. Early efficacy signals exist for strong somatostatin receptor (SSTR)-targeted therapy in SCLC and FAP-targeted therapy in NSCLC, but evidence remains limited. Prospective trials with standardized protocols and dosimetry are needed to define TRT's role in lung cancer treatment.

Microsatellite-stable metastatic colorectal cancer (MSS mCRC) is currently treated with chemotherapy and targeted agents based on RAS and BRAF mutational status. Although these therapies offer initial benefit, most patients rapidly develop resistance, with fewer than 20% remaining progression-free at two years. This review aims to synthesize emerging evidence on the metabolic mechanisms driving treatment resistance in MSS mCRC, with a particular focus on the immune-metabolic signature (IMMETCOLS) classification. We conducted a comprehensive review of preclinical models, transcriptomic datasets, and clinical trial results addressing metabolic adaptations to chemotherapy and targeted therapies in MSS mCRC. The IMMETCOLS framework defines three metabolic subtypes-IMC1, IMC2, and IMC3-each associated with distinct resistance mechanisms. IMC1 exhibits glycolysis and transforming growth factor-β (TGF-β)-dependent signaling enriched in inflammatory fibroblasts, conferring resistance to chemotherapy. IMC2 relies on oxidative phosphorylation and glutamine metabolism, supporting antioxidant defenses and resistance to both cytotoxic agents and anti-EGFR therapies. IMC3 demonstrates lactate-fueled respiration and pentose phosphate pathway activation, contributing to redox balance, DNA repair, and resistance to targeted therapies such as anti-BRAF or KRAS inhibitors. All subtypes display metabolic plasticity under therapeutic pressure. Emerging clinical data support tailoring targeted therapy combinations based on IMMETCOLS subtype, particularly in BRAF- and HER2-positive populations. Understanding subtype-specific metabolic rewiring in MSS mCRC offers novel opportunities to overcome drug resistance. Targeting the metabolic vulnerabilities defined by the IMMETCOLS signature may improve response durability and inform precision treatment strategies.

Cancer is the second leading cause of death globally and in the United States, second only to cardiovascular disease. Unlike many cardiovascular conditions, cancer is often less preventable, manageable, and curable-even with ongoing technological advancements in medicine. The adverse effects of cancer treatments on cancer patients remain profound due to shared cellular characteristics between cancerous and normal cells; one of the primary adverse effects is treatment-induced inflammation. These inflammatory responses aim to eliminate cancerous cells but often damage normal tissues. Notably, inflammatory side effects vary considerably across the growing diversity of therapeutic approaches. This study reviewed studies between 2007 and 2024, comparing the inflammatory profiles associated with five major radiation therapies (RTs): Three-Dimensional Conformal Radiation Therapy (3D-CRT), Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), Stereotactic Body Radiation Therapy (SBRT), and Proton Beam Therapy (PBT)-each characterized by distinct mechanistic and therapeutic features. In addition to each radiation modality eliciting distinct inflammatory responses, tissue-specific variability further complicates clinical outcomes. Accordingly, this review also undertakes a cross-tissue comparison of radiation-induced inflammation, with a focus on the gastrointestinal (GI) system, central nervous system (CNS), and skin. However, the variation in treatment modalities and organ-specific inflammatory biomarkers greatly hinders direct comparison across studies. Finally, this review highlights potential inflammatory mitigations, including ambroxol, that may be employed synergistically with RTs, minimizing side effects and enhancing patient outcomes. Taken together, while all modalities offer therapeutic value alongside certain limitations, proton-based therapy demonstrates the greatest potential for minimizing toxicity though its broader adoption remains limited by cost-effectiveness concerns.

The convergence of DNA nanotechnology with nanofluidics has catalyzed a transformative shift in precision drug delivery. DNA origami, a self-assembled nanoscale architecture constructed via programmable base pairing, offers atomically precise control over size, shape, and function-making it an ideal scaffold for site-specific therapeutic cargo loading and release. When integrated into nanofluidic systems, these origami nanostructures form intelligent platforms capable of navigating biological barriers, sensing intracellular cues, and delivering payloads in a spatially and temporally controlled manner. This review explores the fabrication principles, design strategies, and intracellular trafficking mechanisms that underpin the efficacy of these smart nanofluidic DNA origami systems. We highlight key stimuli-responsive features such as pH-triggered unfolding, enzyme-cleavable hinges, redox-sensitive disassembly, and light-mediated gate release. Case studies from preclinical models demonstrate their superiority in overcoming drug resistance, enhancing tumor selectivity, and minimizing systemic toxicity compared to conventional nanocarriers. We also evaluate methods for surface modification, channel integration, and stimulus modulation using electron-beam lithography and soft lithography techniques. Additional biosafety and scalability challenges are discussed, alongside regulatory and immunogenicity considerations. The review concludes by outlining future directions involving AI-assisted DNA origami design, microfluidic diagnostics, and digital therapeutics. The synthesis of programmable nanocarriers with smart fluidic control represents a new frontier in targeted therapy, combining modularity, precision, and adaptability. As such, nanofluidic DNA origami systems hold immense promise for next-generation therapeutics in oncology, gene therapy, and personalized medicine, paving the way for dynamic and autonomous intracellular delivery platforms with real-world translational potential.

During radiation treatment, reactive oxygen species (ROS) and nitrogen species (RNS) are produced and, by extension, DNA adducts known as 8-hydroxy-2'-deoxyguanosine (8-OHdG) and 8-nitroguanine (8-NG), respectively. However, one of the most common side effects induced by radiotherapy is skin toxicity, which affects patients' quality of life. In the present study, we aimed to investigate the potential predictive value of 8-OHdG and 8-NG by exploring the correlations between the alterations in the concentration levels of the two lesions and radiation-induced tissue injury upon exposure to external beam radiotherapy. For the purpose of this work, we collected blood serum samples from 33 breast cancer patients who received adjuvant radiotherapy. To conduct statistical analysis, we used: (1) linear adjustment to correlate the percent changes of 8-OHdG and 8-NG with the degree of toxicity; and (2) polynomial adaptation and exponential fitting to correlate the percent changes of 8-OHdG and 8-NG with the correlation coefficient r for the development of radiation dermatitis, respectively. According to our findings, there is a statistically significant correlation between the alterations in the 8-OHdG and 8-NG levels and skin grade toxicity across time and varying radiation doses (p < 0.05). Both DNA lesions seem to possess a promising predictive role in radiation dermatitis, while the severity and exact grade of radiation-induced skin toxicity can be determined.

This commentary discusses the FDA's drug approvals in 2025, with a particular focus on cancer therapies and the role of companion diagnostics (CDx). Cancer has emerged as the leading therapeutic area, accounting for 35% of all new drug approvals, largely driven by targeted therapies, with kinase inhibitors representing nearly half of these drugs. Many of the drugs have received orphan drug designations and/or have utilized the Accelerated Approval Program. A key finding was the widespread adoption of the drug-diagnostic co-development model, in which a CDx assay is developed along with the drug and used for patient selection in clinical trials. However, a significant challenge is the frequent lack of concurrent drug and CDx assay approvals. The absence of an analytically and clinically validated CDx assay may pose a challenge for healthcare providers in accurately identifying eligible patients, potentially delaying access to appropriate therapy. The FDA's cancer drug approvals for 2025 highlight an ongoing commitment to precision medicine, with several new targeted treatments, such as antibody-drug conjugates and kinase inhibitors, where CDx assays play an important role in identifying the appropriate patient population.

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 escape mechanisms. To overcome these limitations, bispecific antibodies (bsAbs) represent an innovative class of therapeutic agents that have shown promising results across various medical fields. They have been developed to engage two distinct targets simultaneously, such as tumor antigens, immune effectors, or immunomodulatory checkpoints, thereby enhancing anti-tumor activity and reducing the risk of resistance. There are 17 bsAbs approved for clinical use in various countries, with numerous others currently in active development and over 600 bsAbs undergoing clinical trials worldwide. Among these, 11 have received FDA approval for the treatment of hematologic malignancies as well as solid tumors, including uveal melanoma, metastatic non-small cell lung cancer, small cell lung cancer, and biliary tract cancers. Although some studies have explored bsAbs in gynecological cancers, this area remains underdeveloped compared to other oncology fields. Most ongoing studies in this area are still in their early phases (phase I or phase II), and there is a need for optimization in terms of antibody design, efficacy, and safety profiles. Therefore, the purpose of this review is to present a comprehensive summary of the current research on bsAbs in gynecological cancers, with a focus on endometrial, cervical, and ovarian cancers. We will highlight ongoing clinical trials, discuss the mechanisms of action of these agents, and explore their potential benefits in enhancing treatment outcomes.

The realization that the composition and functionality of gut microbiota have an impact on the outcome of immune checkpoint inhibition (ICI) therapy of cancer has initiated research into the potential of microbiota management as adjunctive therapy. Fecal microbiota transplantation can improve the outcome of ICI, but for optimal donor selection, safety, and large-scale implementation, there remain bottlenecks. Alternative strategies, such as the use of selected bacterial species, require fundamental knowledge of the underlying mechanisms governing the interaction between (intestinal) microbiota and the immune system. Gut microbiota also appears to be able to colonize the tumor microenvironment. Some bacterial species directly or indirectly promote tumor growth. Other defined species have tumoricidal properties. These findings and insights are now being used to further optimize the functionality of the immune system and shape the tumor microenvironment in order to improve the outcome of ICI.

Chemotherapy has profoundly shaped modern oncology, evolving from early cytotoxic approaches to biologically informed strategies. In glioblastoma (GBM), the highly aggressive primary brain tumor, precision medicine does not rely on the identification of a single crucial oncogenic driver but integrates biologically informed stratification strategies to predict treatment response, resistance, and therapy-induced adaptation. This review recapitulates the historical milestones of chemotherapeutic development in neuro-oncology, with particular emphasis on GBM. As the main chemotherapeutic agent currently used in GBM, temozolomide (TMZ) initially represented a major therapeutic breakthrough; however, its clinical use has progressively unveiled the biological and clinical limitations of conventional cytotoxic paradigms. While TMZ exerts antitumor activity through DNA damage-induced apoptosis, accumulating experimental evidence indicates that it may also elicit adaptive responses, ultimately supporting tumor progression and therapy resistance. By integrating historical milestones with recent molecular understanding, this review highlights how improved knowledge of therapy-induced adaptations may inform emerging precision medicine strategies in GBM, underscoring the need for tailored treatments to overcome tumor heterogeneity and adaptive responses.

The aim was to determine the transcriptomic features of tumor and stromal cells in direct contact within tumor nodules in luminal and triple-negative breast cancer. Spatial transcriptomic profiling was performed using the Visium 10x platform on FFPE tumor tissue sections from 10 patients with luminal breast cancer and 9 patients with triple-negative breast cancer. Manual morphological annotation of spots and evaluation of differentially expressed genes (DEGs) in identified spot clusters were performed using Loupe Browser v8.0.0 (10X Genomics, USA). Activated biological processes were assessed using the Enrichr online resource and the GO Biological Process 2025 database. Ligand-receptor pairs were identified using the CellChat package (v2.0) in R (v4.4.2). In luminal breast cancer, mixed cluster (tumor cells colocalized with stromal cells) was characterized by overexpression of genes encoding S100A family Ca2+-binding proteins (S100A4, S100A8, S100A9), matrix metalloproteinases (MMP2, MMP7, MMP14), cytokeratins (KRT5, KRT7, KRT15, KRT23, KRT81), the mesenchymal marker VIM, and epithelial-mesenchymal transition (EMT)-associated genes (ICAM1, PRRX1) compared to tumor-only cluster. In triple-negative breast cancer, mixed cluster showed overexpression of S100A2, S100A8, S100A9, the epithelial gene KRT6B, the cancer stem cell marker CD44, and NOTCH2, which is associated with negative regulation of EMT. In both breast cancer subtypes, mixed cluster showed transcriptomic enrichment of gene sets associated with regulation of the ERK/MAPK cascade, apoptosis, and cell adhesion and migration. Ligand-receptor pairs associated with cell-cell contact, EMT, and immune response were also detected in colocalized cells, with a broader spectrum of these pairs observed in luminal breast cancer. This study assessed the transcriptomic characteristics of directly contacting tumor and stromal cells and identified the spectrum of ligand-receptor pairs mediating their interactions. Characterizing the properties of cells at the tumor-stroma interface helps unravel mechanisms of breast cancer progression and identify novel diagnostic markers and therapeutic targets.

Liquid biopsy (LB) is a complex of procedures aimed at the detection of tumor-derived fragments (nucleic acids, proteins, cells, etc.) persisting in the blood or other body fluids. It can be utilized for early cancer diagnosis, analysis of biomarkers of tumor drug sensitivity and prognosis, monitoring of minimal residual disease (MRD), etc. Circulating tumor DNA (ctDNA) is an accessible and reliable LB analyte as it may contain tumor-specific mutations and is amenable to efficient detection by next-generation sequencing (NGS) or droplet digital PCR (ddPCR). High level of ctDNA is typically associated with increased tumor burden and poor prognosis, whereas treatment-related ctDNA clearance increases the probability of a favorable disease outcome. Major efforts have been invested in enhancing the analytical performance of ctDNA detection. Stimulation of apoptosis of tumor cells by irradiation of cancer lumps has been shown to result in a transient but modest increase in ctDNA concentration. There are several sophisticated modifications of ultra-deep NGS protocols, which discriminate between "true" low-copy mutation-specific signals and sequencing artifacts. Slowing physiological ctDNA decay by interfering with liver macrophages and circulating nucleases has shown promise in animal experiments. Reproducibility of ctDNA-based LB assays remains insufficient for samples with ultra-low content of ctDNA; hence, interlaboratory harmonization of ctDNA testing procedures is of paramount importance.

Lung cancer remains the leading cause of cancer mortality worldwide, with progress limited by tumor heterogeneity, drug resistance, and conventional therapy limitations. Nanotechnology-enabled drug delivery offers a transformative approach, enabling the precise engineering of nanocarriers for selective targeting, controlled release, and reduced toxicity. Recent innovations include inhalable systems that achieve localized pulmonary deposition, stimuli-responsive nanocarriers that release drugs in response to tumor microenvironment cues, and nano-immunotherapies that synergize with immune checkpoint blockade. Exosome-based vesicles further offer biomimetic advantages of low immunogenicity and natural tissue tropism. In parallel, theranostic platforms integrate treatment with imaging to enable real-time monitoring of drug delivery and tumor response. This review synthesizes mechanistic advances and translational developments in lung cancer nanomedicine, with emphasis on strategies that overcome biological barriers such as hypoxia, extracellular matrix density, and efflux pump activity. Clinical progress between 2020 and 2025 highlights next-generation antibody-drug conjugates, nanoparticle vaccines, and gene-loaded systems, several of which have reached regulatory approval or advanced trial stages. Together, these advances highlight the potential of nanocarriers to transform lung cancer therapy into more precise, personalized, and less toxic interventions.

Glioblastoma (GBM) is a complex condition with a poorly understood pathophysiology and no effective treatment to date. The present article highlights the role of canonical and non-canonical signal transducer and activator of transcription 3 (STAT3) interactions with nuclear factor kappa-light-chain-enhancer of activated B cells (NF-&#x3ba;B) in the modulation of the mitochondrial melatonergic pathway in GBM microenvironment pathophysiology. The capacity of STAT3 and NF-&#x3ba;B to interact to upregulate the mitochondrial melatonergic pathway is suppressed systemically over the course of aging, thereby attenuating the capacity to achieve inflammation resolution. The suppressed capacity to induce the mitochondrial melatonergic pathway systemically is partly driven by the dramatic 10-fold decrease in pineal melatonin over aging. The attenuation of pineal melatonin in the first half of sleep over aging and aging-accelerating conditions disinhibits the effects of cortisol in the second half of sleep. This decrease in the melatonin/cortisol ratio alters the nature of night-time dampening and resetting in preparation for the coming day by altering cellular and intercellular homeostatic interactions. Aging and aging-accelerating conditions, by impacting the night-time melatonin/cortisol ratio, also suppress the capacity of the vagal nerve to resolve inflammation. This further contributes to systemic changes that influence GBM pathoetiology and ongoing pathophysiology. Aging-associated changes in night-time dampening and resetting provide a novel framework on which many previously disparate bodies of data on GBM pathophysiology can be collated. This has numerous future research, prevention, and treatment implications.

The aim of this multicenter study was to assess patient characteristics and short-term survival outcomes of first-line (1L) enfortumab vedotin plus pembrolizumab (EVP) as compared with conventional chemotherapy in locally advanced or metastatic urothelial carcinoma (la/mUC). The database included 642 patients with la/mUC diagnosed between January 2008 and December 2025 at 12 collaborating hospitals. Baseline characteristics and follow-up data, including overall and organ-specific objective tumor response according to the RECIST v1.1, progression-free survival, and duration of response, were compared among the 1L regimens. Treatment-related adverse events (TRAEs) were graded according to the CTCAE v5.0 in patients treated with 1L EVP. The objective response and disease control rate were higher with 1L EVP than with chemotherapy (66% vs. 42% and 83% vs. 68%, respectively). The organ-specific response rate for liver metastatic lesions was 85%. Median progression-free survival (95% confidence interval) for 1L EVP, gemcitabine plus cisplatin, and gemcitabine plus carboplatin was 14.5 months (10.5-not determined), 10.5 months (8.4-13.3), and 9.2 months (6.7-14.2), respectively. In the safety analysis set including 40 patients, all-grade TRAEs occurred in 36 (90%) patients, including grade 1-2 events in 30 (75%) and grade 3-4 toxicities in 6 (15%). Grade 3-4 TRAEs included skin toxicity (7.5%), anorexia (5.0%), anemia (5.0%), gastrointestinal disorders (2.5%), renal dysfunction (2.5%), and interstitial lung disease (2.5%). The median number of administered EV cycles was 4 (range, 1-13), 5 (2-13), and 10 (4-13) in the overall, responder, and complete-response populations, respectively. EV dose modifications and interruptions were frequent in the initial 2 months but rare thereafter. This multicenter study provides real-world evidence on short-term outcomes and safety with 1L EVP, highlighting its impact on the evolving treatment landscape for la/mUC.

Intravesical Bacillus Calmette-Gu&#xe9;rin (BCG) is the standard therapy for non-muscle invasive bladder cancer (NMIBC); however, many patients experience recurrence or progression. We examined how urinary immune signals and the urinary microbiome change across BCG and are related to outcomes. In this single-center prospective cohort study, adults with NMIBC underwent transurethral resection of bladder tumor (TURBT), followed by BCG induction. Urine was collected before TURBT, before BCG, after BCG induction, and three months later. Urine sediment mRNA (PD-L1, PD-L2, CD33, and CD204) was quantified using TaqMan &#x394;Ct. The urinary microbiome was profiled using 16S rRNA gene sequencing, and diversity, composition, and taxon balance were evaluated using nonparametric tests, PERMANOVA, repeated-measures correlations, and mixed-effects models. We analyzed the relationship between the urinary microbiome and prognosis. Twenty-three patients were analyzed; ten recurrences, eight progressions, and three deaths were observed. Relative to baseline, CD33 increased after BCG and after three months; PD-L2 increased immediately after BCG and returned to baseline by three months; PD-L1 and CD204 increased after BCG. Shannon alpha-diversity was unchanged, but total read count was higher at three months, with stable beta-diversity and dispersion. Higher PD-L1 expression was associated with lower Actinobacteria abundance in the bladder cancer microenvironment. A higher post-BCG Firmicutes/Bacteroidetes ratio was associated with worse prognosis, with the clearest signal for progression-free survival (PFS) observed in the univariate Cox models. Higher post-BCG Corynebacterium and Enterobacteriaceae abundance was associated with better PFS. BCG was associated with higher urinary PD-L1/PD-L2 and myeloid marker transcripts, while overall community structure remained stable. These exploratory data support that pre-BCG microbial features may be related to early response, and post-BCG profiles may reflect durability and survival. Urine immune-microbiome profiling could be a feasible, noninvasive adjunct for monitoring and risk stratification in NMIBC.

The green synthesis of silver nanoparticles (AgNPs) has recently gained prominence as a sustainable and eco-friendly alternative to conventional physical and chemical methods. Utilizing biological entities such as plant extracts, bacteria, fungi, and biomolecules, the method acts by both reducing and stabilizing mechanisms. It does not use any harmful chemical substances, thus proving to be eco-friendly. Green-synthesized AgNPs exhibit enhanced biocompatibility, stability, and targeted delivery of the drug due to the use of naturally derived surface capping agents. These unique characteristics allow selective interference with cancer cells. The mechanism involved is the generation of reactive oxygen species (ROS), the induction of apoptosis, DNA damage, and cell cycle arrest. Green AgNPs also possess broad-spectrum antimicrobial, catalytic, antiparasitic, and anti-inflammatory properties, supporting the fact that they can be utilised in biomedical fields such as drug delivery, bioimaging, biosensing, tissue engineering, and regenerative medicine. Recent advancements have focused on controlling NP size, shape, and surface functionality to maximize efficacy while simultaneously minimizing cytotoxicity. This review provides a comprehensive analysis of the latest green synthesis strategies, their characterizations, and the molecular mechanisms by which they exert anticancer effects. Recent patents highlight the clinical potential of AgNPs in cancer therapy. US Patent 12201650 (2025) describes green synthesis using Caralluma sinaica, while other patents (WO2007001453, US7462753) outline adaptable biomedical formulations. Studies on biogenic AgNPs also show significant tumor inhibition and selective cytotoxicity against cancer cells. Furthermore, the article discusses current biomedical applications and critically evaluates the limitations, such as reproducibility, toxicity concerns, and scalability for clinical translation. Addressing these challenges is essential for the integration of green AgNPs into mainstream cancer therapeutics. The convergence of nanotechnology and biologically derived synthesis opens promising avenues for the development of safe, effective, and environmentally sustainable medical innovations.

Immune checkpoint inhibitor (ICI) therapy has revolutionized metastatic melanoma treatment, yet only a subset of patients respond effectively, and the treatment can induce a variety of immune-related adverse events (irAEs), including colitis. The gut microbiome plays a critical role in determining patient responses to immunotherapy, prompting exploration of gut-modifying strategies such as prebiotics, probiotics, and fecal microbiota transplantation (FMT) to overcome both primary and acquired resistance and improve treatment outcomes. Prebiotics, defined as dietary substrates that selectively support the growth and/or activity of beneficial gut microorganisms, represent a feasible and safe strategy for microbiome reshaping. Plant-derived prebiotics like castalagin, inulin, fructooligosaccharides, galactooligosaccharides, mushroom extract, kale extract, and konjac glucomannan offer unique advantages over synthetic or animal-derived alternatives due to their natural fiber content alongside their ability to enhance gut microbial diversity. Prebiotics are known to achieve health benefits by selectively stimulating beneficial gut bacteria, producing short-chain fatty acids (SCFAs) that modulate the host immune system, suppressing pathogenic microbes, enhancing mucin production, and modulating systemic and gut-associated immune responses. SCFAs generated through prebiotic fermentation influence host innate and adaptive immunity and regulate metabolic activity via inhibition of histone deacetylases (HDACs), influencing mTOR/MAPK signaling and cytokine production. They also act as ligands for G-protein-coupled receptors (GPCRs), altering intracellular calcium and cAMP to modulate immune cell gene expression. However, the specific mechanisms by which individual prebiotics interact with host genetics, beneficial gut bacteria, and their metabolites are not very well understood. This is crucial to optimize their therapeutic potential in cancer immunotherapy. This review synthesizes current evidence on plant-derived prebiotics, highlighting the impact of beneficial gut bacteria and their metabolites. Given their established safety for human consumption, prebiotics represent a promising, low-risk option to improve gut microbiome composition and potentially enhance immunotherapy and clinical outcomes in cancer.

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms that typically arise from the pleura but may occur in various extrathoracic sites. Primary intraparenchymal pulmonary SFTs without pleural attachment are exceptionally uncommon and often pose diagnostic and therapeutic challenges. We report the case of a middle-aged female patient presenting with progressive dyspnea and a large mass in the left lower lobe on imaging. Computed tomography revealed a well-circumscribed, hypervascular mass occupying the left lower lobe. Bronchoscopic and percutaneous biopsies were nondiagnostic, and surgical resection was pursued. Intraoperatively, the tumor was found to arise from the lung parenchyma without pleural involvement. Histopathological examination demonstrated a spindle-cell neoplasm with the typical "patternless pattern," and immunohistochemistry confirmed nuclear STAT6 positivity, establishing the diagnosis of SFT. The postoperative course was uneventful apart from a transient pulmonary embolism, which was successfully treated. The patient was discharged in good condition and is under regular radiologic surveillance. SFTs of the lung are rare and often mimic more common pulmonary tumors radiologically. Histologic confirmation with STAT6 immunohistochemistry is crucial for accurate diagnosis. Complete surgical excision remains the mainstay of treatment. Given the risk of late recurrence-especially in large tumors-long-term imaging follow-up is mandatory. This case highlights the importance of considering SFT in the differential diagnosis of large pulmonary masses, the critical role of STAT6-based histopathologic confirmation, and the necessity for prolonged surveillance even after complete resection.

Breast cancer is a leading cause of cancer death in women worldwide. One of the major causes of death from breast cancer is metastatic disease, which results from the malignant cells invading and migrating through blood vessels to distant sites. Several studies have shown that metastasis is facilitated by haemostatic proteins. Breast cancer is characterized by a haemostatic imbalance, which is tilted more to a procoagulant state with resultant thrombotic complications. These elements that are involved in thrombosis also play key roles in different aspects of breast cancer growth, including cancer proliferation and progression, cancer survival, angiogenesis, and metastasis. Some of these elements include platelets, endothelial cells, coagulation factors, and fibrinolytic proteins. There is a close relationship between cancer and many of the haemostatic elements. They are usually increased in metastatic breast cancer and have found use as predictive and prognostic markers. Some have been validated in breast cancer. Due to their seemingly active roles in breast cancer progression, some of the haemostatic proteins are being developed as diagnostic tools in the management of breast cancer. They are equally seen as potential targets for the development of novel therapies in breast cancer or repurposing drugs in current use for the same gain. This review highlights the role haemostatic proteins play in breast cancer progression, and their diagnostic and therapeutic relevance.
