The safety and efficacy of tislelizumab, alone or in combination with chemotherapy, for the treatment of non-small cell lung cancer: a systematic review of clinical trials.

BACKGROUND: Tislelizumab is an anti-programmed death-1 (PD-1) monoclonal antibody with a construction that enables it to have a higher affinity to its target. We aimed to evaluate tislelizumab's safety and efficacy for treating non-small cell lung cancer (NSCLC). METHODS: Embase, Scopus, PubMed, Web of Science, and Google Scholar were searched up to December 20, 2022. The review only included randomized controlled trials (RCTs) that evaluated the safety or efficacy of tislelizumab for treating patients with lung cancer. The revised Cochrane risk-of-bias tool (RoB2) was utilized to evaluate study quality. RESULTS: There were four RCTs identified, which included 1565 patients with confirmed locally advanced or metastatic squamous and/or non-squamous types of NSCLC. Treatment with tislelizumab was associated with better progression-free survival (PFS) and objective response rate (ORR), particularly when used in combination with chemotherapy. Almost all patients in both arms reported at least one treatment-emergent adverse event (TEAE). Decreased hematologic indexes accounted for more than 20% of the grade ≥ 3 TEAEs in the tislelizumab plus chemotherapy group. The proportion of TEAE that led to death in the tislelizumab plus chemotherapy arms ranged from 3.2 to 4.2%. Hypothyroidism, pneumonitis, and hyperglycemia were the most frequently noted immune-mediated adverse events in the tislelizumab group. CONCLUSIONS: Tislelizumab, whether used alone or in combination with chemotherapy, seems to demonstrate both a safety and efficacy as a treatment for NSCLC.

Therapeutic Effect of Resveratrol and its Novel Formulations on Lung Cancer: Focus on Biological Aspects and Underlying Pathways.

Lung cancer is a leading cause of mortality and morbidity worldwide. Due to significant advances in therapeutic strategies, patients' survival and life quality have been improved, however there is still an urgent requirement for developing more effective therapeutic methods. Resveratrol, a natural polyphenol with numerous biological potentials, has been widely studied. It has shown therapeutic potetial in various diseases including neurodegenerative diseases, cardiovascular disorders, and cancers through the regulation of key cellular signaling such as apoptosis, as well as molecular pathways such as microRNA modulation. It has been reported that resveratrol acts as an anticancer agent against lung cancer in vivo and in vitro. Resveratrol could combat against lung cancer by modulating various molecular targets and signaling pathways involved in oxidative stress, inflammation, apoptosis and autoghagy and also microRNAs expression. Moreover, novel delivery systems and analogs have recently been introduced to promote the anticancer impacts of resveratrol. In this article, we review current evidence on the anticancer effects of resveratrol and its novel formulations in the treatment of lung cancer with a focus on underlying mechanisms.

Adverse Events of Cannabidiol Use in Patients With Epilepsy: A Systematic Review and Meta-analysis.

Importance: Epilepsy is one of the most common neurologic disorders globally. Cannabidiol (CBD) has been approved for the treatment of epilepsy, but its use has been associated with several different adverse events (AEs). Objective: To investigate the frequency and risk of AEs developing in patients with epilepsy who are using CBD. Data Sources: PubMed, Scopus, Web of Science, and Google Scholar were searched for relevant studies published from database inception up to August 4, 2022. The search strategy included a combination of the following keywords: (cannabidiol OR epidiolex) AND (epilepsy OR seizures). Study Selection: The review included all randomized clinical trials that investigated at least 1 AE from the use of CBD in patients with epilepsy. Data Extraction and Synthesis: Basic information about each study was extracted. I2 statistics were calculated using Q statistics to assess the statistical heterogeneity among the included studies. A random-effects model was used in cases of substantial heterogeneity, and a fixed-effects model was used if the I2 statistic for the AEs was lower than 40%. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Main Outcomes and Measures: Frequency of each AE and risk of developing each AE in patients with epilepsy using CBD. Results: Nine studies were included. Overall incidences of 9.7% in the CBD group and 4.0% in the control group were found for any grade AEs. The overall risk ratios (RRs) for any grade and severe grade AEs were 1.12 (95% CI, 1.02-1.23) and 3.39 (95% CI, 1.42-8.09), respectively, for the CBD group compared with the control group. Compared with the control group, the CBD group had a greater risk for incidence of serious AEs (RR, 2.67; 95% CI, 1.83-3.88), AEs resulting in discontinuation (RR, 3.95; 95% CI, 1.86-8.37), and AEs resulting in dose reduction (RR, 9.87; 95% CI, 5.34-14.40). Because most of the included studies had some risk of bias (3 raised some concerns and 3 were at high risk of bias), these findings should be interpreted with some caution. Conclusions and Relevance: In this systematic review and meta-analysis of clinical trials, the use of CBD to treat patients with epilepsy was associated with an increased risk of several AEs. Additional studies are needed to determine the safe and effective CBD dosage for treating epilepsy.
