Study of IL-2 receptor expression after chemoimmunotherapy in patients treated for metastatic malignant melanoma.

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
Using flow cytometry, cellular IL-2 receptors were studied before and following chemoimmunotherapy combination in 20 patients with metastatic malignant melanoma (MMM). Patients received cisplatin (100 mg/m2) at days 1 and 28, recombinant IL-2 by continuous infusion from days 3 to 6, 17 to 21, 31 to 34, and 45 to 49. Interferon-alpha (IFN-alpha) was given subcutaneously three times weekly. In terms of clinical response, we observed 55% objective response (complete: 15%). When pretreatment blood samples were compared with those of healthy donors, we did not observe any change in low (alpha chain) and high affinity receptor (alpha + beta) expression. In contrast, intermediate affinity p75 (beta chain) expression was decreased significantly (P < or = 0.0001) in MMM patients. During treatment, we found a dramatic increase of beta chain as well as high affinity (alpha + beta) expression in responding patients, as soon as IL-2 therapy began. Furthermore, the increase of beta chain expression was limited to natural killer (NK) cells (CD56+). In non-responding patients, on the other hand, increase of both receptors was seen only at day 31. These data suggest the involvement of beta chain expression in the mechanism of cell activation after chemoimmunotherapy. Moreover, this early beta chain expression is correlated with the clinical response to chemoimmunotherapy.
