Consolidation therapy impact on survival outcomes in young patients with intracranial primary diffuse large B-cell lymphoma achieving complete remission: a propensity score matching analysis.

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
Objectives: Primary central nervous system lymphoma is an extremely aggressive type of non-Hodgkin lymphoma, and there is no consensus regarding the optimal management strategy for this disease. This study aimed to analyze the impact of consolidation therapy among young patients with intracranial primary diffuse large B-cell lymphoma (DLBCL). Methods: This retrospective study analyzed the clinical data of 55 young patients (age < 60 years) with intracranial primary DLBCL who achieved complete remission (CR) after high-dose methotrexate (HD-MTX)-based chemotherapy from March 2001 to October 2021. Among these patients, 33 patients received consolidation therapy, and 22 patients did not. Overall survival (OS) and disease-free survival (DFS) were compared between the two groups via Kaplan-Meier analysis, the multivariate Cox proportional hazards method, and propensity score matching (PSM). Results: The median follow-up time was 60.1 months. A total of 13 patients (23.6%) died, and 20 patients (36.4%) experienced recurrence. Patients who received consolidation therapy had higher 2-year OS (96.8% vs. 71.1%, Conclusions: Consolidation therapy improved DFS in young intracranial primary DLBCL patients achieving CR after HD-MTX-based chemotherapy. Autologous stem cell transplantation and radiotherapy showed comparable consolidation benefits. Good performance status correlated with favorable outcomes. Adding rituximab to induction chemotherapy may improve OS in patients without consolidation therapy, but it might be unnecessary for those eligible for consolidation. Further research involving a larger patient cohort is warranted to ascertain rituximab's efficacy.
