1 · What the graph read from 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.

2 · The registry

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

backgroundSecondary Central Nervous Lymphoma (SCNSL) is an aggressive lymphoma with poor outcomes. Consensus regarding consolidation with thiotepa-based autologous transplant (ASCT) for SCNSL is lacking.

methodsOur retrospective Singapore study examined survival outcomes post ASCT in 27 patients (median age 57 years) with SCNSL in two tertiary cancer centres from 2013 to 2024.

resultsFive (18.5%) patients had de novo SCNSL, 14 (51.9%) patients had isolated CNS relapsed SCNSL and 8 (29.6%) patients had synchronous relapsed SCNSL. At the time of ASCT, 16 (59.3%), 7 (25.9%) and 4 (14.8%) patients were in CR, PR and SD/PD respectively. Median follow up for the 22 relapsed SCNSL patients was 63 (5-109) months with a median PFS and OS of 11.5 and 30 months, respectively, and 4-year PFS and OS rates of 35.0% and 48.0%, respectively. In our analysis, females demonstrated superior median and 4-year PFS and OS compared to males, likely related to difference in age and performance status. On multivariate analysis, CR/PR at time of ASCT trended toward an improved OS (HR 7.86, p = 0.06) although this was not statistically significant.

conclusionOur data suggests that in secondary CNSL, chemo-sensitivity would likely confer good outcomes with thiotepa-based consolidation ASCT. Conversely, patients responding poorly to salvage chemotherapy may consider alternatives including CAR-T cell therapy.
