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

backgroundMaffucci syndrome is characterized by the sporadic occurrence of multiple enchondromas together with multiple hemangiomas. Patients with Maffucci syndrome are at increased risk of developing different kinds of malignant tumors. CASE PRESENTATION: We report on a 39-year-old woman who was diagnosed with Maffucci syndrome together with intrahepatic cholangiocarcinoma (IHCC). Heterozygous somatic mutations in the isocitrate dehydrogenase 1 and 2 (IDH1/IDH2) genes are associated with a number of different tumor types (e.g. IHCC) and also with Maffucci syndrome. For IHCC, mutations in IDH1/IDH2 are associated with higher survival rates. IHCC tissue as well as normal liver tissue and peripheral blood were analyzed for IDH1/IDH2-mutations in our patient. In the tumor sample, we identified a recurrent somatic IDH1-mutation affecting Arg132, while in normal liver tissue and peripheral blood, no variants were detected, as expected.

conclusionThis case report presents the second patient in the literature exhibiting the features of Maffucci syndrome along with cholangiocarcinoma. This supports the hypothesis that IDH1/2-mutations, which can be present in different types of tumor tissue simultaneously, arise during embryonic development in a mosaic pattern; as a result, a more aggressive follow-up is proposed in patients with Maffucci syndrome to exclude neoplasms.
