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

aimsMolecular profiling is important for cancer diagnosis and treatment. For many advanced stage lung cancer patients, cytology specimens may be the only materials available for molecular testing. The aim of this study is to evaluate the utility of Next-Generation Sequencing (NGS) of cytology specimens for the molecular profiling of lung adenocarcinoma.

methodsNGS was performed on cell blocks of pleural effusions and fine-needle aspiration (FNA) samples of lung adenocarcinoma to determine the mutation status of EGFR, KRAS, PIK3CA, BRAF, ALK, PDGFRA, and DDR2. Then, quantitative Real-Time PCR (qPCR) was performed and the results were compared to those of NGS. Next, NGS was performed on available histological specimens from the same patients. Last, DNA Quality Index analysis was performed to further explore the applicability of using cytology samples as the source for NGS.

resultsNGS detected mutations in EGFR, PIK3CA, and KRAS. NGS and qPCR results showed high concordance. NGS exhibited advantages over qPCR in detecting non-hotspot mutations and providing accurate information for allele sequence and mutation frequency. NGS of cytological and histological samples from the same patients showed high concordance. DNA Quality Index analysis showed that DNA extracted from cell blocks of pleural fluid was of similar quality compared to FFPE tissue blocks.

conclusionsNGS can be successfully performed on both FNA and pleural fluid samples from lung adenocarcinomas. The high quality DNA of FFPE cell block of pleural effusion makes it the first choice for molecular profiling, especially when cytology specimens are the only available samples for molecular profiling.
