Feasibility of personalized treatment concepts in gastrointestinal malignancies: Sub-group results of prospective clinical phase II trial EXACT.

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
objectiveAdvances in high-throughput genomic profiling and the development of new targeted therapies improve patient's survival. In gastrointestinal (GI) malignancies, the concept of personalized medicine (PM) was not investigated so far. The aim of this prospective study was to evaluate the efficacy of a personalized treatment in GI patients who failed standard treatment.
methodsOut of the original prospective clinical phase II EXACT trial, 21 (38%) GI cancer patients who had no further treatment options were identified. A molecular profile (MP) via a 50 gene next generation sequencing (NGS) panel in combination with immunohistochemistry (IHC) was conducted using real-time biopsy tumor material. Results were discussed by a multidisciplinary team (MDT) to translate the individual MP in an experimental treatment.
resultsOf the 55 patients originally included in the EXACT trial, 21 (38%) suffered from GI malignancies. The final analysis showed that 15 (71%) patients had experienced a longer progression-free survival (PFS) upon experimental targeted treatment (124 d, quartiles 70/193 d), when compared with the PFS achieved by the previous conventional therapy (62 d, quartiles 55/83 d) (P=0.014). Thirteen (62%) patients receiving targeted treatment experienced a disease control according to Response Evaluation Criteria in Solid Tumors (RECIST). Median overall survival (OS) from the start of experimental therapy to time of censoring or death was 193 d (quartiles 115/374 d).
conclusionsPM was not investigated in GI malignancies so far in a prospective trial. This study shows that treatment based on real-time molecular tumor profiling led to a superior clinical benefit, and survival as well as response was significantly improved when compared with previous standard medications.
