The efficacy and safety of radiotherapy and immunotherapy with or without anlotinib in driver gene-negative advanced non-small cell lung cancer.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Radiotherapy paired with immune checkpoint inhibitors (ICIs) has benefited patients with driver gene-negative NSCLC, although treatment resistance remains an obstacle. Anlotinib, a broad-spectrum tyrosine kinase inhibitor, has potential to reinforce immunotherapy by modifying the tumor environment. This study investigates whether incorporating anlotinib can amplify the efficacy of combined treatment protocols. Methods: A total of 203 individuals diagnosed with stage IIIB-IV NSCLC were retrospectively assessed. Treatment occurred at the First Affiliated Hospital of Bengbu Medical University between 2021 and 2023. Patients were grouped into those receiving radiotherapy and immunotherapy (n=123) and those receiving anlotinib in addition (n=80). Clinical outcomes assessed included PFS, OS, response metrics, and treatment-related side effects. Results: Over a median follow-up of 26 months, the group receiving anlotinib showed enhanced median PFS (10.0 months vs 6.0 months, P = 0.043 HR: 0.708, 95% CI: 0.496-1.009). However, there was no statistically significant difference in overall survival (OS) between the two groups (median OS: 20.0 vs. 18.0 months; P = 0.344, HR:0.848 95% CI:0.597-1.205). the RT+IO+A regimen demonstrated a 10% higher ORR than the RT+IO regimen (45.0% vs. 35.0%), while the DCR was similar between the two groups (88.8% vs. 91.1%). Toxic effects were manageable but more frequent in the triple-therapy group. Conclusion: The triple regimen improved disease stabilization but did not yield OS benefits. Due to the increased toxicity associated with the addition of anlotinib, Future research is required to weigh advantages against added toxicity.
