BackgroundCardiac damage is a significant risk of chemotherapy. Elevated circulating cardiac troponin I was suggested as a marker for early detection of cardiac damage.ObjectiveWe aim to assess the predictive value of cardiac troponin I for chemotherapy-induced cardiotoxicity in cancer patients.MethodsWe searched PubMed, Web of Science, Embase, and CNKI. Nine prospective studies involving 2033 cancer patients (pts) were included in the meta-analysis. Troponin I (TnI) levels in patients who underwent chemotherapy were categorized into cardiac troponin I (cTnI) positive and negative groups based on the cutoff concentrations described in the included studies. The cumulative effects of chemotherapy-induced cardiotoxicity between the cTnI-positive and cTnI-negative patients were represented as a summarized risk difference (RD) value with a 95% confidence interval. Subgroup analysis and sensitivity analysis were employed to address heterogeneities. Stata software (version 12.0) was utilized for the analysis.ResultscTnI-positive pts represented significant cardiotoxicity compared to cTnI-negative pts, as a decline in left ventricular ejection fraction (LVEF): RD = 0.279 [95% CI (0.248-0.311), p = 0.000, I2 = 81.3%, 8 trials], heart failure (HF): RD = 0.117, [95% CI (0.090-0.144), p = 0.000, I2 = 77.8%, 6 trials], arrhythmias: RD = 0.057 [95% CI (0.028-0.086), p = 0.000, I2 = 0.0%, 3 trials], and cumulative events: RD = 0.318 [95% CI (0.272-0.364), p = 0.000, I2 = 73.5%, 3 trials]. No statistically significant difference in cardiac death, acute pulmonary edema, and acute coronary syndromes between cTnI-positive pts and cTnI-negative pts was identified.ConclusionsAn increase in circulating troponin I serve as a potential biomarker that reflecting the high risk of early cardiotoxicity in cancer patients who have undergone chemotherapy. The presence of intrinsic unadjusted confounding factors in the reports suggests the need for further study to address this question.

Metastatic or recurrent bone sarcomas are often associated with an unfavorable prognosis, posing a formidable challenge in extending patients' survival. Currently, regorafenib has shown promise in treating metastatic and recurrent bone sarcomas. However, there is a lack of consensus on its efficacy and safety. This systematic review and meta-analysis aims to consolidate existing data to assess the efficacy and safety of regorafenib in bone sarcomas.

Ototoxicity is a known side effect of cisplatin chemotherapy. The efficacy of various medications used to prevent or reduce ototoxicity in adults receiving cisplatin has not been thoroughly described in the literature.

T-cell acute lymphoblastic leukemia (T-ALL) patients often have a poor 5-year event-free survival. The only T-ALL specific drug in clinical practice is nelarabine. A prodrug of the deoxyguanosine analog ara-G, nelarabine is a rationally designed agent selective for the treatment of T-cell malignancies. Originally approved for relapsed/refractory T-ALL, it is increasingly used in T-ALL therapy and is currently being evaluated in upfront treatment. Whilst the clinical use of nelarabine has been the topic of multiple review articles, a thorough overview of the preclinical data detailing the molecular underpinnings of its anti-leukemic activity is lacking, which is critical to inform mechanism-based use. Thus, in the present article we conducted a semi-systematic review of the literature and critically evaluated the preclinical knowledge on the molecular pharmacology of nelarabine. Whilst early studies identified ara-G triphosphate to be the principal active metabolite and nuclear DNA synthesis to be a key target, many fundamental questions remain that could inform upon future use of this therapy. These include the nature of nelarabine-induced DNA lesions and their repair, together with additional cellular targets of ara-G metabolites and their role in efficacy and toxicity. A critical avenue of research in need of development is investigation of nelarabine combination therapies, both in the context of current T-ALL chemotherapy regimens and with emerging anti-leukemic agents, and we highlight some areas to pursue. Altogether, we discuss what we can learn from the preclinical literature as a whole and present our view for future research regarding nelarabine treatment in T-ALL.

Macular telangiectasia (MacTel) is a rare retinal condition that can cause vision loss, and anti-vascular endothelial growth factor (anti-VEGF) agents have emerged as a potential treatment. This study aimed to evaluate the clinical outcomes of anti-VEGF therapy in patients with MacTel.

The combination of programmed cell death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors with chemotherapy (CT) is currently under evaluation as a first-line treatment for advanced or recurrent endometrial cancer (EC). This study sought to assess the efficacy and safety of this therapeutic combination in patients with advanced or recurrent EC.

Despite durable responses achieved with Immune Checkpoint Inhibitors (ICIs), data about optimal duration of treatment, especially in the context of adverse events, remain scarce.

Cannabinoids have potential efficacy as prophylaxis for chemotherapy-induced nausea and vomiting (CINV), but no recent meta-analysis has reported on their relative efficacy compared to other antiemetics. The aim of this meta-analysis is to examine the relative efficacy of cannabinoids for prophylaxis of CINV.

Targeted therapies are promising treatment options for fit patients with untreated chronic lymphocytic leukemia (CLL). However, there is a lack of data on their relative efficacy and safety. The aim of this systematic review was to assess the relative efficacy and safety of first-line targeted therapies (including venetoclax [VEN], obinutuzumab [OBI], ibrutinib [IBR], and other options) for physically fit patients with untreated CLL.

In recent years, immune checkpoint inhibitors (ICIs) have shown significant efficacy in treating various malignancies and have become a key therapeutic approach in cancer treatment. However, while ICIs activate the immune system, they can also induce immune-related adverse events (irAEs). Due to the variability in the frequency and severity of irAEs, clinical management faces a significant challenge in balancing antitumor efficacy with the risk of irAEs. Predicting and preventing irAEs during the early stages of treatment has become a critical research focus in cancer immunotherapy. This study aims to evaluate the predictive value of peripheral blood cell counts for irAEs.

Exercise can improve the symptoms of chemotherapy-induced peripheral neuropathy. Traditional pairwise meta-analyses of exercise interventions can only identify the difference in effect between an exercise intervention and usual care. It is necessary to conduct network meta-analyses to establish evidence on the comparative effectiveness of all relevant exercise intervention strategies.

Antibody-drug conjugates are novel effective therapies for metastatic breast cancer. Nevertheless, their toxicity profile can significantly affect patients' quality of life over time.

Neoadjuvant immunotherapy (NIT) has been endorsed by clinical guidelines for the management of DNA mismatch repair deficiency/microsatellite instability-high (dMMR/MSI-H) locally advanced rectal cancer (LARC). Nonetheless, the therapeutic efficacy of NIT in mismatch repair-proficient/microsatellite stable (pMMR/MSS) non-metastatic rectal cancer (RC) remain pending matters. Therefore, a meta-analysis was carried out to assess the efficacy and safety of NIT in patients with non-metastatic pMMR/MSS RC.

IntroductionThis study aims to evaluate the effect of bevacizumab treatment on the incidence of hypertension in patients with ovarian cancer.MethodsA comprehensive search of PubMed, Scopus, Embase, Cochrane, Web of Science, and Google Scholar databases was conducted until August 2024. We included only randomized clinical trials that compared ovarian cancer patients treated with Bevacizumab to those treated with other therapies. The primary outcome was the relative risk (RR) of developing hypertension, stratified by grade. Statistical analyses were performed using a random-effects model to account for heterogeneity between studies. Subgroup analyses were conducted based on hypertension severity (grade ≥2 and grade ≥3) and disease stage. Sensitivity analyses and publication bias assessments were also performed.ResultsA total of 11 randomized trials were included, comprising 5212 patients. The meta-analysis revealed that patients receiving Bevacizumab had a significantly higher risk of hypertension compared to controls (RR = 2.91, 95% CI: 1.65-5.16, P = 0.0002). Subgroup analysis showed that the risk of grade ≥2 hypertension was 1.68 times higher (95% CI: 0.92-3.07), and grade ≥3 hypertension was 5.10 times higher (95% CI: 2.46-10.55) in the Bevacizumab group. Sensitivity analysis confirmed the robustness of these findings, and no significant publication bias was detected.ConclusionBevacizumab treatment in ovarian cancer significantly increases the risk of hypertension, particularly severe hypertension (grade ≥3). These findings underscore the need for vigilant blood pressure monitoring and management in patients receiving Bevacizumab to mitigate cardiovascular complications and optimize treatment outcomes.

Cannabis is commonly used among patients with cancer for palliative benefit. As the use of immune checkpoint inhibitors (ICIs) for cancer therapy increases, there is concern about potential interactions between ICIs and cannabis. Preclinical studies suggest that cannabis leads to immunosuppression, which could impair the function of ICIs. However, only a few clinical studies have investigated this relationship. The goal of this review is to synthesize reported immunomodulatory effects of cannabis in patients with and without cancer in order to better understand whether these preclinical findings translate to the clinical space.

The clinical efficacy of anti-vascular endothelial growth factors (anti-VEGFs), corticosteroids, and their combined treatment for diabetic macular edema (DME) has been substantiated by numerous studies. However, it remains uncertain whether the therapeutic benefits of the combined treatment with corticosteroids and anti-VEGFs is superior to those of anti-VEGF monotherapy. Consequently, we conducted a meta-analysis to compare the efficacy and safety of combined treatment with dexamethasone or triamcinolone and anti-VEGF versus anti-VEGF monotherapy in DME treatment.

PD-1 inhibitors have shown promising efficacy in enhancing OS and AEs as second-line therapies for patients with advanced esophageal squamous cell carcinoma (ESCC). However, there remains no clear consensus on which PD-1 inhibitor provides the best balance between efficacy and safety. To address this key issue in the second-line treatment of ESCC, we conducted a network meta-analysis (NMA) with a focus on OS benefits, particularly in patients with different levels of PD-L1 expression.

Niraparib is approved as a maintenance treatment for ovarian cancer due to its potential to prolong progression-free survival.
