The ratio of Bcl-2/Bim as a predictor of cisplatin response provides a rational combination of ABT-263 with cisplatin or radiation in small cell lung cancer.

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
backgroundCisplatin-based chemotherapy and radiotherapy are the most commonly used treatments for small cell lung cancer (SCLC). However, despise initially dramatic response, the response duration of SCLC patients is variable and resistance to chemo- and radio-therapy inevitably develops.
objectiveThe aim of the study is to investigate the role of Bcl-2 family proteins in predicting SCLC sensitivity to cisplatin treatment, and to identify the potential sensitizer of cisplatin or ratiation treatment in SCLC.
methodsWe collected cisplatin sensitivity data from public available database, and evaluated its possible association with mRNA or protein expression of Bcl-2 family members in SCLC cell lines.
resultsThe IC50 value of cisplatin was significantly correlated with the ratio of Bcl-2/Bim mRNA expression in 33 SCLC cell lines (P= 0.041) as well as the ratio of Bcl-2/Bim protein expression in 7 SCLC cell lines (P= 0.0252). Furthermore, a BH3-mimetic ABT-263 was found to be able to sensitize SCLC cells to cisplatin or radiation. The synergistic and additive antitumor activity of ABT-263 combined with cisplatin or radiation was associated with the enhanced apoptosis, which may be caused by the disruption of Bcl-2 binding to Bim by ABT-263.
conclusionsOur study indicates that the ratio of Bcl-2/Bim could be a SCLC response predictor to cisplatin, and ABT-263 addition could be an effective strategy to improve the activity of chemo- or radio-therapy in SCLC.
