Clinical and dynamic circulating cytokines profile features of long-term progression-free survival benefit to immune checkpoint inhibitors in advanced non-small cell lung cancer.

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
backgroundImmune checkpoint inhibitors (ICIs) offer durable progression-free survival (PFS) benefit in a subset of patients with advanced non-small cell lung cancer (NSCLC). However, the predictors of long-term PFS (LTPFS) remain unclear.
methodsAdvanced NSCLC patients receiving first-line ICIs monotherapy at Guangdong Lung Cancer Institute between December 2017 and August 2022 were identified. Predictive value of different characteristics was evaluated in LTPFS (PFS ≥ 24 months) compared with short-term PFS (STPFS, PFS ≤ 3 months). Circulating cytokine levels were evaluated in paired peripheral blood samples collected before and after ICIs treatment.
resultsAmong 202 patients identified and 171 included (median follow-up: 41.0 months), 44 (25.7%) experienced LTPFS, associated with a 5-year overall survival (OS) rate of 81.2%. Squamous NSCLC, intermediate or poor lung immune prognostic index (LIPI) score, and liver metastases, were negatively associated with LTPFS. High tumor mutational burden (TMB, ≥ 10 mutations/megabase) was enriched in LTPFS compared to STPFS (P = 0.002). Patients with both high TMB and PD-L1 demonstrated the greatest survival benefit from first-line ICIs monotherapy (median PFS: 24.5 months, median OS: 67.0 months). Thirty-eight peripheral blood samples were collected before and after ICIs treatment from 10 patients with LTPFS and 9 with STPFS, which revealed increased CCL11 (P = 0.013) and decreased IL1RA (P = 0.001) and IL17A (P = 0.003) levels in LTPFS after ICIs treatment.
conclusionDistinct clinical characteristics, including TMB, PD-L1, pathologic subtypes, LIPI score, number of organs involved, metastatic sites, and dynamic circulating cytokines profile features, can distinguish NSCLC patients achieving LTPFS from those with STPFS following first-line ICIs monotherapy.
