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

backgroundLeukapheresis is often performed in cancer patients to harvest stem cells, manufacture therapeutic vaccines, or follow immunologic response to therapy. We have recently described the minimal impact of leukapheresis on normal donors. Here we provide additional immunologic data from patients with advanced cancer who underwent leukapheresis.

methodsUsing data from cancer patients on clinical trials who had leukapheresis (n = 64) or peripheral blood draws only (n = 90) as controls for immune analysis, we evaluated the impact of leukapheresis on number and function of lymphocytes.

resultsIn the leukapheresis group, median age was 63.5 (range 38-82); 87.5 % were male. Comparing pre- and post-leukapheresis values within the groups, with each patient as its own control, there was no significant difference in enzyme-linked immunosorbent spot (ELISPOT), antivector humoral response, absolute lymphocyte count (ALC), or T cell number. Twelve patients completed three leukaphereses with subsequent ELISPOT analysis; seven had increased responses to flu (1.1- to 2.3-fold) with an even distribution around no change. Nineteen patients had matched ALC values after completing three leukaphereses with no significant change from baseline.

conclusionsThese data provide evidence that leukapheresis has no detectable effects on a cancer patient's immune system in terms of number or function. These results contribute to a growing body of evidence refuting the hypothesis that a patient's immune competence is meaningfully affected by the procedure. Limitations include a restriction to 2-L leukapheresis procedure and small sample size.
