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

The aim of this study was to investigate the associations between secondary mutations of c-KIT/PDGFRα and acquired imatinib resistance or efficacy of sunitinib in Chinese patients with gastrointestinal stromal tumors (GISTs). Mutations of c-KIT (exons 9, 11, 13, 14, 17, and 18) and PDGFRα (exons 12 and 18) in tumor samples of 50 patients were analyzed by direct sequencing. A total of 50 samples before imatinib and 52 samples after imatinib were collected. Among 52 samples after imatinib, 38 samples were imatinib resistant and 14 samples were imatinib sensitive. All patients before imatinib treatment had primary mutations of c-KIT exon 11 (n = 45) or exon 9 (n = 5), and no PDGFRα mutations were found in these patients. After imatinib treatment, 25 of 38 (65.8 %) resistant tumors had secondary mutations in c-KIT exon 13 (n = 10), exon 14 (n = 1), exon 17 (n = 12) and exon 18 (n = 2), while no secondary mutations of c-KIT were found in 14 sensitive tumors (P < 0.001), indicating the close association of c-KIT secondary mutations with imatinib-acquired resistance. In our study, 19 patients received sunitinib treatment after the failure of imatinib, and it seemed that the median progression-free survival (7 vs. 19 months, P = 0.244) in patients with secondary mutations (n = 13) was lower than that in patients without secondary mutations (n = 6). Secondary mutations of c-KIT were significantly associated with acquired resistance to imatinib in Chinese GIST patients, and whether secondary mutations of c-KIT could influence the efficacy of sunitinib needed to be further investigated.
