Bacillus Calmette-Guérin (BCG) is the standard adjuvant therapy for high-risk non-muscle-invasive bladder cancer (NMIBC); however, a substantial proportion of patients develop BCG-unresponsive disease with limited bladder-preserving options. The objective of this study was to determine whether combination immunotherapy provides superior clinical efficacy and safety compared with single-agent immunotherapy for patients with BCG-unresponsive NMIBC.

Extensive-stage small cell lung cancer (SCLC) carries a poor prognosis and has limited therapeutic options. The addition of immune-checkpoint inhibitors (ICIs) to platinum-etoposide (PE) chemotherapy has become an important first-line treatment strategy. However, the comparative benefits and harms of different first-line chemotherapy-based regimens, including ICI-containing combinations, remain unclear.

Combining immune checkpoint inhibitors (ICIs) with chemotherapy has become a major clinical research focus. Patients with extensive-stage small-cell lung cancer (ES-SCLC) have been treated with different first-line ICI combinations in randomized controlled trials (RCTs), but the optimal combination strategy has not yet been determined. Our aim was to evaluate this strategy through a systematic review and meta-analysis.

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, yet cancer-related fatigue (CRF) remains a frequent but poorly characterized adverse effect. We evaluated CRF incidence during ICI treatment in neoadjuvant and adjuvant settings.

This study aimed to systematically synthesize and separately quantify the pooled safety profiles of bispecific antibodies (BsAbs) targeting PD-1/CTLA-4 or PD-1/VEGF in patients with non-small cell lung cancer (NSCLC), and to descriptively summarize class-specific safety patterns.

Advanced gastric and gastroesophageal junction (G/GEJ) adenocarcinomas are characterized by an aggressive course and a very poor prognosis. Due to the limited benefit of immunotherapy in patients with HER2-negative tumors, new therapeutic targets are sought. Zolbetuximab is a chimeric monoclonal antibody targeting the CLDN18.2 protein, which is overexpressed in 50-80% of gastric cancers.

Immune checkpoint inhibitors (ICIs) activate antitumor immunity by targeting immune checkpoint molecules such as cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), programmed death receptor 1 (PD-1), and programmed death-ligand 1 (PD-L1). They have emerged as a key therapeutic modality for multiple malignancies. Nevertheless, excessive immune activation may trigger a spectrum of immune-related adverse events (irAEs). Though uncommon, uveitis is a sight-threatening irAEs that can result in permanent visual loss. The risk and prognostic outcomes of ICIs-associated uveitis remain poorly defined to date. Therefore, we performed this meta-analysis to systematically assess the correlation of ICIs therapy with uveitis risk and prognosis, with the goal of providing evidence-based recommendations for clinical identification and management of this ocular complication.

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, yet clinical responses remain highly variable, and microbiome-associated findings lack reproducibility across studies. Increasing evidence implicates the gut microbiome in modulating ICI efficacy; however, findings remain inconsistent at the taxonomic level, raising the possibility that functionally convergent immunological mechanisms may underlie this apparent variability. To address this, a critical synthesis was conducted, integrating bibliometric mapping of publications indexed in the Web of Science Core Collection (2013-2025; n = 2,195) with a secondary analysis of ClinicalTrials.gov to evaluate interventional activity. Bibliometric approaches assessed scientific production, thematic evolution, and co-citation structure, complemented by a cross-cohort functional integration of representative clinical and preclinical studies to evaluate whether microbiome-ICI interactions converge on shared immunological pathways despite divergent taxonomic signatures. Publication output increased steadily, with a marked translational surge following landmark clinical studies in 2018 and a peak in trial initiation in 2021. Thematic analyses revealed a shift from mechanistic and tumor-centered research toward clinically oriented and intervention-driven themes, including microbiome modulation, microbial metabolites, and the tumor microenvironment. Although individual response-associated taxa differed substantially across independent cohorts, qualitative functional integration supported a model of convergence in immunomodulatory pathways involving short-chain fatty acid production, dendritic cell activation, and CD8+ T-cell priming. Collectively, these findings suggest that apparent taxonomic inconsistencies across microbiome-ICI studies may reflect underlying functional convergence rather than biological contradiction, supporting a shift toward function-based frameworks for biomarker discovery and microbiome-directed immunomodulation.

Colorectal cancer stem cells (CRC-SCs) contribute to treatment resistance, tumor recurrence and disease progression. Despite therapeutic advances, CRC-SCs frequently evade eradication and sustain tumor propagation. Although multiple molecular pathways have been implicated in this resistance, current preclinical evidence remains fragmented. This systematic review aims to synthesize preclinical evidence on the molecular mechanisms underlying CRC-SC resistance to modern anticancer therapies. A systematic search of PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted to identify peer-reviewed original studies published between 2015 and 2025. Eligible studies investigated molecular mechanisms of CRC-SC resistance to chemotherapy, targeted therapy, immunotherapy, and other therapeutic modalities. Risk of bias was assessed using QUIN for in vitro studies and SYRCLE for in vivo studies. A total of 26 studies met the inclusion criteria. Synthesis of findings showed that CRC-SC resistance is driven by interconnected mechanisms, including adaptive signaling pathways, epigenetic reprogramming, enhanced DNA damage response, and protective interactions within the tumor microenvironment. Several studies reported that combination treatments targeting these mechanisms attenuated stemness characteristics and restored therapeutic sensitivity. Overall, CRC-SC resistance arises from multiple intrinsic and extrinsic mechanisms, supporting further preclinical and translational evaluation of combination strategies.

Chemotherapy-related fatigue, sleep disturbance, and psychological distress significantly impair quality of life (QoL) in cancer patients. Traditional Chinese medicine (TCM) non-pharmacological therapies are increasingly used as supportive care, yet their comparative effectiveness remains unclear. This study aimed to evaluate and compare five TCM-based interventions for improving QoL and emotional well-being in chemotherapy patients.

Chemotherapy resistance remains a major clinical challenge in the treatment of gastrointestinal (GI) cancers. Mitochondrial remodeling contributes to chemoresistance through several interconnected functional modules, including metabolic reprogramming, elevation of the apoptotic threshold, adjustment of the reactive oxygen species setpoint, and mitophagy-mediated mitochondrial quality control. Polysaccharides and polysaccharide-based systems may represent promising candidates for modulating mitochondria-associated dysfunctions because of their structural diversity, biological activity, and generally favorable biocompatibility in specific experimental settings.

Immune checkpoint inhibitor (ICI) therapy for colorectal cancer (CRC) can be accompanied by endocrine adverse events, yet the comparative risk across commonly used regimens remains unclear. We therefore conducted a network meta-analysis of randomized controlled trials in CRC published up to November 22, 2025, estimating risk ratios (RRs) with 95% confidence intervals (CIs) and assessing risk of bias. Six RCTs were included. Relative to conventional therapy, ICI-based regimens were associated with a higher thyroid-related toxicity burden. Pembrolizumab and ICI+tyrosine kinase inhibitor (TKI) significantly increased the risk of hypothyroidism, whereas hyperthyroidism was significantly higher with ICI+TKI and ICI plus chemotherapy plus an anti-angiogenic antibody (ICI+Chem+Antiangio-Ab). Grade 1-2 adverse events were consistently increased across ICI-based treatments. For thyroiditis, diabetes mellitus, adrenal insufficiency, and grade 3-4 adverse events, effect estimates were imprecise with wide 95% CIs; nevertheless, SUCRA rankings tended to place ICI+TKI toward the higher-risk end for thyroiditis and diabetes. These findings indicate that ICI-containing strategies in CRC increase risks of endocrine adverse events-particularly for thyroid dysfunction-supporting the need for proactive endocrine monitoring and standardized management, while highlighting the limited precision of current evidence for rarer endpoints and severe toxicity.

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. Immune checkpoint inhibitor (ICI) monotherapy has shown limited efficacy in PDAC, whereas the potential clinical value of first-line ICI-based combination regimens remains unclear. Through a systematic review and meta-analysis, this study aimed to evaluate the efficacy and safety of first-line ICI-based combination regimens in advanced PDAC.

Immune checkpoint inhibitors (ICIs) have transformed cancer therapeutics yet frequently induce renal injury and multi-organ immune-related adverse events (irAEs) that present substantial clinical management challenges. Critical evidence gaps persist regarding dynamic immune microenvironment interactions and optimal organ-protective strategies.

Sarcomas are rare, aggressive and unpredictable tumors that arise from mesenchymal tissues. Despite treatment, outcomes for advanced or metastatic cases remain poor. Anlotinib is a new oral tyrosine kinase inhibitor that blocks multiple angiogenic pathways and has shown encouraging results in solid tumors. This review aims to summarize and clarify the current evidence on anlotinib's role in treating sarcoma.

Esophageal squamous cell carcinoma (ESCC) remains one of the most aggressive and lethal cancers, with high incidence and mortality rates in East Asia. Neoadjuvant chemotherapy (NC) has traditionally been the standard approach for improving resectability in ESCC, but its limited efficacy in achieving complete pathological responses and enhancing survival has driven interest in combining it with immune checkpoint inhibitors (ICIs), resulting in neoadjuvant chemoimmunotherapy (NIC). Based on randomized controlled trials (RCTs), this meta-analysis compares the risks and clinical benefits of NIC versus NC in resectable ESCC patients.

Gastric cancer is a highly prevalent malignancy of the digestive tract in China. Conventional chemotherapeutic drugs and human epidermal growth factor receptor 2 (HER2)‑targeted agents such as trastuzumab remain limited by significant challenges in the treatment of GC, including high rates of drug resistance, significant toxicity and adverse effects, and suboptimal tolerability. The advent of antibody-drug conjugates (ADCs) has marked a paradigm shift in the therapeutic landscape. This review systematically summarises the structural design, mechanisms of action, and current clinical applications of ADCs in HER2-positive or HER2-low advanced gastric cancer.

Cancer is a leading cause of death worldwide, affecting individuals of reproductive age. Although conventional treatments are essential for cure and survival improvement, they adverse effects on male and female fertility. This systematic review, registered in PROSPERO (CRD42024538296) and conducted according to PRISMA guidelines, aimed to evaluate the impact of these treatments on the reproductive system of murine animal models. A literature search across PubMed, Scopus, Web of Science, and Embase yielded 30 included studies. Most studies used C57BL/6 J and Wistar rats. The most frequently drugs were cyclophosphamide, cisplatin, and doxorubicin, which were mainly administered intraperitoneally at varying doses. Assessed outcomes included sperm analysis, ovulation rate, reproductive efficiency, histological alterations, and gene expression. Alkylating agents caused significant testicular degeneration and follicular toxicity, severely impairing fertility. Antimetabolites and antineoplastic antibiotics induced severe reproductive damage in both sexes. Topoisomerase and microtubule inhibitors demonstrated relevant reproductive toxicity, although data are limited. In women, alterations in ovarian and uterine functions are observed, and in men, the effects range from dysfunctions of the hypothalamic-pituitary-gonadal axis to alterations in the structural and functional integrity of gametes. Both radiotherapy and chemotherapy target cellular DNA; however, they act through distinct mechanisms. Most studies are with males, and studies with females, when present, often lacked comprehensive evaluation. The methodological quality assessment shows a lack of blinding and allocation concealment. In general, the studies focused on doses, treatment regimens, and experimental protocols. Therefore, conventional treatments negatively affect fertility in murine models, highlighting need for fertility preservation strategies in cancer patients.

Olanzapine is an established antiemetic for the prevention of chemotherapy-induced nausea and vomiting (CINV), although the optimal dose for balancing efficacy and tolerability remains uncertain. We conducted a systematic review and network meta-analysis comparing olanzapine 2.5 mg, 5 mg, and 10 mg for CINV prophylaxis.

HER2-positive gastric and gastroesophageal junction (GEJ) cancers have poor prognosis despite standard trastuzumab-based chemotherapy. Immune checkpoint inhibitors (ICIs) may enhance therapeutic efficacy when combined with trastuzumab.
