t (11;18)(q21;q21) chromosome translocation (A1446-M1150) of MALT lymphoma in buccal mucosa.
Article in Journal of cancer research and clinical oncology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe t(11;18)(q21;q21) chromosome translocation is frequent in gastric MALT lymphoma, but the t(11;18)(q21;q21) chromosome translocation is very rare in other sites of MALT lymphomas. We investigated the possibility that MALT lymphoma occurred in the right buccal mucosa of a 66-year-old Japanese woman who had the t(11;18)(q21;q21) chromosome translocation.
methodsTumor specimens were examined by light microscopy and immunohistochemistry. To investigate where the present case has API-MALT1 fusion, we used the nested PCR and FISH analysis.
resultsSome colonized lymphoid follicles with mantle zone were observed on low-power field, and centrocyte-like cells and monocytoid B cells were observed on high-power field. Immunohistochemical staining of the tumor was positive for bcl-2, CD20, CD79a, CD43, Lambda, Kappa and was negative for CD10, IgG, IgG4, IgM, cyclin D1, bcl-6, CK (AE1/3), Helicobacter pylori. Using the nested PCR and FISH analysis, present case had the t(11;18)(q21;q21) chromosome translocation (A1446-M1150).
conclusionWe report that MALT lymphoma in buccal mucosa has the t(11;18)(q21;q21) chromosome translocation (A1446-M1150) by using the nested PCR and FISH analysis. This is the first report of the t(11;18)(q21;q21) chromosome translocation (A1446-M1150) of MALT lymphoma in the oral cavity.
