Extensive-stage small cell lung cancer: Is prophylactic cranial irradiation necessary in the era of immunotherapy with MRI surveillance?
Article in Precision radiation oncology, 2023. 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
Objective: The role of prophylactic cranial irradiation (PCI) in treating extensive-stage small-cell lung cancer (ES-SCLC) has been controversial. This study aimed to comprehensively analyze the efficacy of PCI for the treatment of ES-SCLC under active brain magnetic resonance imaging (MRI) surveillance. Methods: Patients with ES-SCLC with no brain metastases (BM) confirmed by MRI at the time of diagnosis who responded well to first-line chemoimmunotherapy at three general hospitals were retrospectively included. Overall survival (OS), progression-free survival (PFS), and cumulative incidence of BM were compared between patients who underwent PCI and those who did not. Results: In total, 66 consecutive patients treated between March 2019 and December 2021 were included in our dataset. Seventeen patients underwent PCI (PCI group) and 49 patients did not (non-PCI group). In comparison with the non-PCI group, PCI did not provide OS (median OS: 18.53 Conclusion: Compared to active MRI surveillance, first-line chemoimmunotherapy followed by PCI did not improve the prognosis of patients with ES-SCLC. Further studies are warranted to evaluate the therapeutic effects of PCI following chemoimmunotherapy.
