Chemotherapy-induced nausea and vomiting (CINV) is a common and severe adverse effect of breast cancer (BC) treatment that compromises treatment adherence and quality of life. This meta-analysis aims to assess the prevalence and risk factors of CINV in BC patients, thereby providing clinical insights for its prevention and improvement. Patient/material and methods: Relevant literature was identified through an extensive search of electronic databases from their inception up to July 10, 2025: PubMed, Web of Science, Embase, Cochrane, CNKI, Wanfang, and VIP databases on prevalence rates, odds ratios (OR), and corresponding 95% confidence intervals (CI) were extracted for analysis.

The aim of the present study was to investigate the prevalence of oral manifestations among patients undergoing chemotherapy.

Immune checkpoint inhibitors (ICIs) combined with standard chemotherapy (CT) or chemoradiotherapy (CRT) have shown promising results in recent randomized controlled trials (RCTs) for advanced or recurrent cervical cancer (CC). However, comprehensive evidence is needed to evaluate their efficacy and safety, particularly in the context of patient subgroups and immune response mechanisms. This meta-analysis aimed to synthesize data from RCTs and apply trial sequential analysis (TSA) to validate findings.

To identify the impact of CT-defined emphysema on efficacy and immune checkpoint inhibitor-related pneumonitis (ICIP) risk among non-small cell lung cancer (NSCLC) patients who receive ICIs.

In proficient mismatch repair (pMMR) non metastatic rectal cancer, standard neoadjuvant chemoradiotherapy (nCRT) yields low pathological and clinical complete response rates. Early randomized trials suggest adding PD 1 inhibitors may increase response but randomized evidence has not been synthesized.

Hyponatremia is the most prevalent electrolyte imbalance in cancer patients. Symptoms potentially signaling hyponatremia include altered mental status, neurological condition, headache, nausea, dizziness, and balance loss. Its management is particularly challenging as it must account for prognosis, treatment-related factors, and quality of life, especially in individuals treated with immune checkpoint inhibitors (ICIs). This systematic review and meta-analysis assessed the incidence of hyponatremia in patients receiving ICIs or immune-based combinations compared with placebo or other anticancer treatments. The review was registered in PROSPERO (CRD420251137412). Eligible studies included randomized clinical trials, quasi-experimental, and observational studies reporting hyponatremia frequency in patients treated with ICIs. Risk of bias was assessed using the ROB 2 tool for randomized studies and ROBINS-I for observational studies. A meta-analysis for proportions was performed using generalized linear mixed models. Proportion was measured for any grade of hyponatremia, grade 1-2, and grade ≥ 3; and three separate subgroup meta-analyses were performed: one for any grade, one for grade 1 or 2, and one for grade ≥ 3. Thirteen studies were included in the quantitative analyses. Any-grade hyponatremia was reported in 7 studies (934 patients, 49 events), with a pooled prevalence of 5.0% (95% CI = [2.3%; 11.9%]; I2 = 81.8%). Grade 1-2 hyponatremia was assessed in 7 studies (314 patients, 36 events) with a pooled prevalence of 1.2% (95% CI = [0.03%; 37.8%]; I2 = 88.2%). Grade ≥ 3 hyponatremia was evaluated in 14 studies (652 patients, 35 events), yielding a pooled prevalence of 5.5% (95% CI = [3.1%; 9.6%]; I2 = 44.8%). No significant small-study effects were detected for grade ≥ 3 events (Egger's test P = 0.313). These findings support routine electrolyte surveillance in patients treated with ICIs and highlight the need for further studies to clarify mechanisms and risk factors and define optimal monitoring strategies to improve both safety and outcomes.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and is the leading cause of cancer-related deaths worldwide. The majority of patients with HCC are diagnosed at an advanced stage, resulting in limited treatment options. In recent years, numerous clinical trials have confirmed that immunotherapy, particularly anti-programmed cell death 1 (anti-PD-1)/programmed cell death ligand 1 (PD-L1), has emerged as a promising treatment for advanced HCC. However, in real-world practice, the clinical efficacy of adding immunotherapy to locoregional therapies remains unknown, representing a knowledge gap.

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy but are complicated by immune-related adverse events, including acute kidney injury (AKI). As clinical experience matures and treatment durations lengthen, initial estimates of ICI-AKI incidence and the perceived risks of resuming therapy may become outdated.

To investigate the association between pretreatment controlling nutritional status (CONUT) score and clinical outcomes for cancer patients treated with immune checkpoint inhibitors (ICIs).

Osimertinib, a third-generation epidermal growth factor receptor (EGFR) inhibitor, was developed to overcome resistance from EGFR-mutant non-small-cell lung cancer (NSCLC). While it offers significant therapeutic benefits, reports have linked Osimertinib to cardiotoxic effects. This study aims to clarify the direct cardiotoxicity of Osimertinib by reviewing clinical trials and cohort studies involving Osimertinib monotherapy compared to other EGFR inhibitors. A search was conducted in online databases. Measured outcomes included risk of heart failure (HF), myocardial infarction (MI), decline in left ventricular ejection fraction (LVEF), arrhythmias, and pericardial effusion. These outcomes were reported as risk ratio (RR) with a random effects model using 95% confidence intervals (CI). Five studies with 19,008 patients (age 68 ± 13, 65% female) were selected. Osimertinib therapy was associated with an increased risk of HF (RR = 1.45, 95% CI 1.19-1.76, p = 0.0002), decline in LVEF (RR = 3.10, 95% CI 1.72-5.59, p = 0.0002) and MI (RR = 1.40, 95% CI 1.09-1.79, p = 0.0078) compared to other EGFR inhibitors. There was no difference in the risk of arrhythmias and pericardial effusion. Osimertinib therapy is associated with an increased risk of HF and a decline in LVEF compared to other EGFR inhibitors, while associations with MI and arrhythmias were less consistent. Although these events are infrequent, their potential severity warrants proactive cardiac monitoring for patients receiving Osimertinib, particularly in patients with pre-existing risk factors.

Despite the significant survival benefit offered by immune checkpoint inhibitors (ICIs) in patients with hepatocellular carcinoma (HCC), a subset of patients still develop drug resistance. Recent evidence suggests that proton pump inhibitors (PPIs) may influence the therapeutic efficacy of ICIs, but the clinical relevance of this interaction remains unclear. This meta-analysis aims to systematically evaluate the association between concomitant PPIs use and clinical outcomes in HCC patients receiving ICIs therapy.

Bone metastases are a frequent and clinically consequential complication of advanced non-small cell lung cancer (NSCLC), associated with substantial morbidity and poor survival. Whether adding radiotherapy (RT) to immune checkpoint inhibitors (ICIs) improves outcomes remains uncertain.

The systematic review and meta-analysis aim to thoroughly assess the efficacy of manual interventions like massage therapy, reflexology, and acupressure techniques in relation to overall symptoms, pain, and quality of life (QOL) in patients suffering from CIPN.

Immune checkpoint inhibitors (ICIs) combined with chemotherapy have become an important area of clinical investigation in the gastric cancer (GC) and gastroesophageal junction cancer (GEJC). In recent years, bispecific antibody therapies have been increasingly explored, including cadonilimab, a programmed death-1/cytotoxic T-lymphocyte-associated antigen 4 (PD-1/CTLA-4) bispecific antibody. Several phase II studies have reported early signals of antitumor activity with cadonilimab, prompting clinical interest in this strategy. However, treatment outcomes vary across studies, and a systematic assessment of the efficacy and safety of cadonilimab plus chemotherapy remains limited. This study aimed to evaluate the efficacy and safety profile of cadonilimab in combination with chemotherapy for gastric adenocarcinoma and gastroesophageal junction adenocarcinoma (G/GEJ adenocarcinoma) through a single-arm meta-analysis.

Acute myeloid leukemia (AML) is the most common acute leukemia in adults. Approximately 30% of patients present alterations in the FMS-like receptor tyrosine kinase 3 (FLT3) gene, which are associated with poor prognosis. FLT3 inhibitors - midostaurin (first-generation), gilteritinib and quizartinib (second-generation) - have been developed to block FLT3 activation. Given the need of optimizing treatment in FLT3-mutated AML, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the safety profiles of FLT3 inhibitors. Following the PRISMA statement, we searched Embase, MEDLINE and Cochrane Library. The Cochrane Risk of Bias Tool for RCTs was used for quality assessment. Of 2132 references, seven RCTs, involving 2409 adult patients, met inclusion criteria: quizartinib and midostaurin in two trials each and gilteritinib in three. The most frequently reported adverse events (AEs) were classified under the System Organ Class (SOC) Blood and lymphatic system disorders (N = 5474, 58.4% of them related to FLT3 inhibitors). The most frequently observed non-hematological AEs were gastrointestinal disorders, pyrexia, elevated ALT/AST and headache. FLT3 inhibitors are not associated with a significant increase in the risk of AEs compared to standard treatments. No meaningful differences in AE risk were observed among the three drugs. The only exception was an higher risk of ALT increased with gilteritinib (RR = 2.40, 95% CI: 1.16-4.95). Future studies should stratify safety outcomes by demographic and clinical characteristics and incorporate long-term follow-up for a more comprehensive safety assessment in clinical practice.

Programmed cell death (PD) protein (ligand [L])-1 inhibitors are established treatments for metastatic non-small cell lung cancer (mNSCLC). In oncology, progression-free survival (PFS) and objective response rate (ORR) are often used as surrogates for overall survival (OS) to inform clinical development; however, there remains uncertainty in the concordance between these endpoints. This study evaluated the impact of a broad set of PD-(L)1 inhibitors on efficacy, explored the relationship between ORR and survival endpoints, and compared PD-1 and PD-L1 treatments for mNSCLC. A dataset of 114 studies was used to conduct a sequential two-stage model-based meta-analysis (MBMA). Firstly, an MBMA with mixed-effects logistic regression was applied to evaluate treatment-specific and clinical covariate effects on ORR. Secondly, MBMAs for OS and PFS were conducted with a mixed-effects semi-parametric proportional hazard approach using digitized Kaplan-Meier curves, with the treatment type, covariates, and ORR as inputs. ORR was demonstrated to be a significant predictor of OS and PFS. Simulations of head-to-head comparisons of treatment types were conducted using these models. Trends in predicted outcomes numerically favored PD-1 over PD-L1 treatments, but differences were not statistically significant. These findings support evidence-based decision-making for late-stage trial designs using ORR data from earlier phase trials, enabling benchmarking of emerging data by adjusting for explained and unexplained sources of variability in existing and emerging data.

Ultrasound (US)-activated nanotherapies represent a transformative frontier in oncology, leveraging the noninvasive deep penetration of acoustic energy for targeted tumor destruction. However, this field lacks a quantitative synthesis to guide the rational design of sono-sensitizing nanoparticles (NPs) and the optimization of therapeutic protocols. To address this issue, we performed a systematic review and meta-analysis of 144 recent research reports, establishing an evidence-based design hierarchy for nano-sonosensitizers. A meta-analysis of 86 in vitro studies revealed a profound synergistic reduction in cell viability when NPs were activated by US (pooled standard mean difference, SMD = -13.16, 95% CI [-14.67, -11.64], p < 0.001). NP size was the most influential design factor. Particles smaller than 50 nm showing the greatest effect in vitro (SMD = -13.32) and strongest tumor reduction in vivo (SMD = 5), a finding consistent with optimal exploitation of the enhanced permeability and retention (EPR) effect for tumor accumulation. Specific roles of materials were identified: polymeric NPs excelled in drug delivery (SMD = -19.36 versus US alone), while inorganic NPs served as direct sonocatalysts. This work provides a definitive quantitative framework to advance US-activated nanotherapy from exploratory discovery to clinical precision. To realize this potential, we recommend the adoption of standardized acoustic dosimetry and material characterization and inclusion of safety studies (ISO 10993. We hope that this review will accelerate the development of fundamental studies and therapeutic US applications for sonosensitizing NPs.

Intra-arterial chemotherapy (IAC), intravenous chemotherapy (IVC), and the combination of both (IVC + IAC) are among the most important treatment options for retinoblastoma, a rare form of childhood cancer. The outcomes of previous studies evaluating the success rates of these methods have been discrepant due to the varying quality of the research as well as the different study types, sample sizes, and definitions of outcomes.

We conducted an etiology-stratified network meta-analysis of first-line systemic therapies for advanced HCC to compare newer regimens beyond sorafenib-based RCT evidence (HBV, HCV, or non-viral).

Early studies indicate that neoadjuvant immune checkpoint inhibitors (ICIs) induce high rates of tumor regression in localized deficient mismatch repair (dMMR) and microsatellite instability-high (MSI-H) gastric and gastroesophageal junction (GEJ) cancers, raising interest in nonoperative management (NOM). Most available data, however, come from small, nonrandomized cohorts. A systematic synthesis was undertaken to better characterize efficacy and safety outcomes.
