The efficacy and safety of immune combination therapy in patients with driver gene-negative non-small cell lung cancer with liver metastasis: a systematic review and network meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to systematically evaluate the efficacy and safety of combination therapies with immune checkpoint inhibitors (ICIs) in patients with driver gene-negative non-small cell lung cancer (NSCLC) and liver metastases. These patients typically have poor prognosis and limited responses to immunotherapy. This study synthesized existing literature by conducting a network meta-analysis to determine the most effective first-line ICI combination regimen to guide clinical treatment decisions.
methodsWe systematically searched the PubMed, Embase, Web of Science, and Cochrane Library databases for Phase III randomised controlled trials published up to 1 August 2024. Eligible studies underscored on patients with driver gene-negative NSCLC with liver metastases and reported progression-free survival (PFS), overall survival (OS), and treatment-related adverse events. Bayesian network meta-analysis was conducted using R (version 4.4.1) and STATA (version 17), with the results reported as hazard ratios (HRs) and 95% confidence intervals (CIs).
resultsFourteen studies including 1,291 patients and 11 ICIs combination regimens were included. Pembrolizumab plus chemotherapy remarkably improved OS (HR, 0.64; 95% CI, 0.41-0.98). For PFS, tislelizumab plus chemotherapy (HR, 0.44; 95% CI, 0.26-0.74) and pembrolizumab plus chemotherapy (HR, 0.59; 95% CI, 0.39-0.90) were superior to other treatments. PD-1 inhibitors, such as pembrolizumab, combined with chemotherapy have shown greater efficacy than PD-L1 inhibitors, particularly for non-squamous cell carcinoma. High-grade adverse events, including hepatotoxicity, were more frequent in patients with liver metastases.
conclusionICI-chemotherapy combinations offer a promising first-line treatment for driver gene-negative NSCLC with liver metastases. The pembrolizumab and tislelizumab combination demonstrated improved OS and PFS with distinct efficacy and safety profiles. Enhanced monitoring of liver function is recommended because of the risk of hepatotoxicity. Further studies are needed to confirm these findings and optimise individualised treatment strategies.
