Efficacy and safety of immune checkpoint inhibitors in post-TKI NSCLC patients harboring EGFR mutations.
Synthesis in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveImmune checkpoint inhibitors (ICIs) have been validated in epidermal growth factor receptor (EGFR) wild-type advanced non-small cell lung cancer (NSCLC) patients. However, there exists no evidence regarding NSCLC patients harboring EGFR mutations, experiencing EGFR-TKI (tyrosine kinase inhibitor) treatment failure. We collected clinical information from real world and conducted a time series-based meta-analysis to determine the efficacy and safety of ICIs in patients harboring EGFR mutations and experienced EGFR-TKIs resistance.
methodsTwenty-two NSCLC patients with EGFR mutations after TKI resistance were included from two hospitals. PubMed, Embase and Cochrane Library were searched for relevant literature published until December 31, 2021. Endpoint outcomes included mortality and progression-free survival (PFS) at different times of follow-up.
resultsIn total, 22 patients showed that the median PFS was 5.6 months (range 2.0-9.0 months). According to treatment strategies, the median PFS was 2.4 months (range 2.0-5.3 months) in the ICI monotherapy group and 5.9 months (range 2.8-9.0 months) in the ICI combined Chemotherapy group. Additionally, sixteen studies, including 5 trials, 10 controlled cohorts and 1 real-world study, were assessed, involving a total of ICI-treated NSCLC patients with EGFR mutation after TKI failure. The 6-month survival and PFS rate were 0.82 (95% CI 0.36-0.97) and 0.55 (95% CI 0.34-0.74), respectively. ICI combined chemotherapy showed the best survival outcome among these groups, as demonstrated by the 12-month survival rate and PFS. No new safety signals were identified with the combination therapy. The frequency of treatment-related adverse events was similar to that in previously reported studies of chemotherapy combined with checkpoint inhibitors.
conclusionsThe addition of ICIs plus chemotherapy may significantly improve progression-free survival among patients with locally advanced or metastatic non-squamous NSCLC who EGFR-TKIs resistance.
