Efficacy of immune checkpoint inhibitor rechallenge in initial immunotherapy responders with advanced non-small cell lung cancer: A single-center retrospective study.
Article in Investigational new drugs, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundThe efficacy of immune rechallenge in patients with advanced non-small cell lung cancer (NSCLC) who responded well to initial immune checkpoint inhibitor (ICI) treatment is becoming a research hotspot. This study was aimed at describing the survival and clinical characteristics after immune rechallenge in initial immunotherapy responders. PATIENTS AND
methodsWe retrospectively identified 104 patients with advanced NSCLC who responded well in the first ICI and were rechallenged with immunotherapy to treat progression between January 2018 and June 2023 at Zhejiang Cancer Hospital. Progression-free survival (PFS) 2 and overall survival (OS) were defined as the time from the first day of the second ICI to the date of progression, death, or last follow-up.
resultsOf 104 enrolled patients, 33 received immune monotherapy, and 71 were rechallenged with combination therapy (34 combined with anti-angiogenesis therapy). Patients with an initial immunotherapy duration exceeding 12 months, compared with a duration within 12 months, achieved a significantly prolonged mPFS2 and mOS (PFS2: 9.2 vs. 3.4 months, P < 0.001; OS: 25.5 vs. 10.7 months, P = 0.006). Patients rechallenged with combination therapy had significantly longer PFS2 than those receiving monotherapy (5.8 vs. 2.5 months, P = 0.040), and showed a favorable OS trend (15.9 vs. 10.1 months, P = 0.301). A significant difference in PFS2, particularly for patients receiving combined treatment with anti-angiogenesis therapy (8.7 vs. 4.6 months, P = 0.011), and a tendency toward longer OS (25.3 vs. 13.7 months, P = 0.090), were observed. Multivariate analysis identified long-term treatment duration (P = 0.005) and combined treatment with anti-angiogenesis therapy (P = 0.030) as independent positive factors associated with PFS after rechallenge.
conclusionImmune rechallenge is recommend for responders with a prolonged initial immunotherapy duration. Combination therapy, particularly that including anti-angiogenic therapy, is an alternative effective approach to immune rechallenge.
