Polymorphism of TS 3'-UTR predicts survival of Chinese advanced gastric cancer patients receiving first-line capecitabine plus paclitaxel.
Article in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
purposeCapecitabine-containing chemotherapy was widely used in clinic medication. We investigated the association of the thymidylate synthase (TS), methylenetetrahydrofolate reductase (MTHFR), and dihydropyrimidine dehydrogenase (DPD) polymorphisms with the clinical outcome of Chinese advanced gastric cancer patients receiving first-line capecitabine plus paclitaxel.
methodsBlood samples were collected prior to treatment from 125 patients with advanced gastric cancer and the TS (two or three repeats of a 28 bp sequence in 5'-untranslated region and 6 bp insertion or deletion in 3'-untranslated region), MTHFR (C677T) and DPD (IVS14+1G > A) polymorphisms were determined using PCR amplification and Sanger sequencing.
resultsThe median age of 125 patients was 58 years (range, 23-76) with female 42 and male 83, and the response rate, median progression-free survival and overall survival (OS) were 43.2 %, 5.2 and 11.0 months. The median OS in patients with TS ins6/ins6 genotype (6.8 months) was significantly shorter than those in patients with ins6/del6 (11.0 months, P = 0.016) and del6/del6 (11.5 months, P = 0.039) genotypes. Cox multivariate analysis also showed that TS ins6/ins6 genotype was the independent poor OS predictor (P = 0.001, HR = 3.182). No significant associations were found between the polymorphisms of TS 5'-UTR/MTHFR and clinical outcome, and no IVS14+1G > A polymorphism of DPD was found in this study.
conclusionsWe first reported that TS 3'-UTR ins6/ins6 genotype could predict the poor survival of advanced gastric cancer patients treated with capecitabine plus paclitaxel, which would be further verified in a large multicenter study.
