In terms of pathological types, most LCs are non-small cell LC (NSCLC), responsible for an estimated 85%[2]. The World Health Business offers classified NSCLC into 3 major classes, including adenocarcinoma, squamous cell carcinoma, and large cell.[3C5] Stages of the disease determine the treatment options for NSCLC.[6] Therefore, stage I-II NSCLC is primarily treated surgically, and advanced NSCLC is treated using platinum-containing doublet chemotherapy as the first line of treatment.[7] Nevertheless, resistance to platinum-based chemotherapy is an essential element affecting the therapeutic effect.[8] With the advent of Immune Checkpoint Inhibitors (ICIs), specially programmed death-1 (PD-1) inhibitors (Pembrolizumab, Nivolumab), and programmed death-ligand 1 (PD-L1) inhibitors (Durvalumab, Avelumab, and atezolizumab), the therapeutic scenery of immunotherapy has been changed in NSCLC.[9] PD-1/PD-L1 inhibitors have revealed a remarkable effect in overall survival relative to chemotherapy in NSCLC.[10,11] PD-1 is usually expressed in varied immunity cells, a modulator of T cells, consisting of T cells and B cells. [12] PD-L1 and PD-L2, the ligands of PD-1, are indicated in the immune cells, as well as SMND-309 with the tumor cells[13]. The immune system and Treg up-regulation are inhibited when PD-1 binds to PD-L1/PD-L2 in the tumor microenvironment; hence, the immune monitoring system cannot fully play its part in removing malignant tumor cells.[14] Immune evasion occurs when tumor cells overexpress PD-L1.[15,16] ICIs repress the binding of PD-1 as well as PD-L1, and reactivate cytotoxic T cells to get rid of malignancy cells.[17] However, the immune balance is usually disrupted when the immune system is activated, and normal cells are over-attacked. Consequently, recent studies possess focused on immune-related adverse events, including cutaneous, pneumonitis, gastrointestinal, and endocrine effects.[18] The findings of a study in mice indicated the inhibition of the PD-1 leads to dilated cardiomyopathy.[19] Study evidence demonstrates ICI is associated with cardiotoxicity of NSCLC, including myocarditis, cardiac conduction abnormalities, and pericardial tamponade.[20C22] PD-1, as well as PD-L1, are synthesized in human being cardiomyocytes, and PD-L1 expression was detected in damaged cardiomyocytes of patients with adverse cardiac events.[23] Most adverse cardiac events are managed using high doses of glucocorticoids.[24] Unlike additional adverse events, cardiotoxicity is life-threatening. Consequently, the tradeoff between security and effectiveness and the potential risk of toxicity to the heart should be considered. In the most recent meta-analysis, the findings showed no designated variations in cardiotoxicity between immunotherapy and chemotherapy.[25] SMND-309 This is because individual adverse cardiac events were not analyzed, and only 3 clinical trials were included with the retrieval date set for February 2017. In recent years, several clinical tests have been carried out and results published in peer-reviewed journals. This meta-analysis will address the cardiac-related adverse events induced by PD-1/PD-L1 inhibitors, and compare PD-1/PD-L1 inhibitors with chemotherapy. Here, more medical randomized controlled tests will become added, and individual cardiac-related adverse events will become detailed. 2.?Methods 2.1. Study indexing This meta-analysis method has been indexed on Prospero (CRD42020156397). We will perform this review as per the Preferred Reporting Item for Systematic Review and meta-analysis statement recommendations.[26]. 2.2. Criteria for including randomized controlled trails (RCTs) 2.2.1. Types of studies This review will consist of all randomized RCTs using.Evaluation of risk of bias in added RCTs The risk of bias of each RCT added will be conducted singly by 2 reviewers (HLL and DTH) based on tool of Cochrane collaboration for examining the risk of bias. added study. The data analysis will become analyzed using Stata15.0 software. Specific adverse cardiac events will become recognized, with particular attention on atrial fibrillation, cardiac arrest, cardiac failure, and pericarditis. This review will become performed as per the Preferred Reporting Item for Systematic Review and meta-analysis statement recommendations. Ethics and dissemination: This study will provide support for the cardiotoxicity linked to the treatment of NSCLC using PD-1/PD-L1 inhibitors. The data in the meta-analysis will become retrieved from completed and published medical trials; therefore, honest review and patient informed consent will not be required.
