Efficacy and safety of first-line high-dose cytarabine in patients with primary CNS lymphoma ineligible for high-dose methotrexate: A case series.

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: Despite recent significant advances, the treatment of elderly patients with primary central nervous system lymphoma (PCNSL) is still challenging due to comorbidities, poor baseline performance status (PS), and drug toxicities. There are proposals to use high-dose cytarabine (HD-araC) in these patients. Methods: Our retrospective study aimed to assess the efficacy and toxicity of HD-araC as an upfront treatment for patients with PCNSL who are ineligible for high-dose methotrexate (HD-MTX). Results: We identified 12 consecutive patients with newly diagnosed PCNSL (out of a total of 68) who received first-line treatment with HD-araC, with or without rituximab (R). Most of them had poor PS and relevant comorbidities. Six patients received this treatment upfront, while the other six received it after discontinuing HD-MTX-(based) therapy. Treatment with HD-araC resulted in poor outcome, limited response, and severe hematological and infectious complications. Patients who had previously received at least one cycle of HD-MTX appeared to have slightly better outcomes, highlighting the importance of HD-MTX in the treatment of PCNSL. Conclusion: Our case series showed limited efficacy and substantial toxicity of (R)-HD-araC in patients with PCNSL ineligible for HD-MTX. This treatment should be omitted in elderly/frail patients to avoid further compromising their quality of life.
