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

Local interleukin 2 (IL-2) therapy is more effective against systemic tumours than systemic IL-2 therapy, but it remains unclear whether IL-2 should be injected intratumourally or peritumourally. To investigate this question, we treated DBA/2 mice bearing a large subcutaneous syngeneic SL2 lymphoma with either intra or peritumoural IL-2 therapy. Both applications enhanced survival, but intratumourally injected IL-2 was more effective than peritumourally injected IL-2. Tumours started to regress 4 days after IL-2 injection. Tumour cells died at the IL-2 injection site, although IL-2 is not directly cytotoxic for SL2 cells in vitro. Tumour cell death correlated well with oedema and extravascular erythrocytes, but less with leukocyte infiltrates. In mice bearing two s.c. tumours, intratumoural application therapy of IL-2 in one tumour caused decrease in size of both tumours in 4-9 days after therapy. However, the IL-2 treated tumours regressed more strongly than the untreated tumours. We conclude that vascular leakage and/or tissue destruction inside the tumour may contribute to the enhanced effect of intratumoural IL-2 therapy compared to peritumoural IL-2 therapy. Hence, we recommend applying of intratumoural rather than peritumoural IL-2 therapy.
