Tissue requirements in lung cancer diagnosis for tumor heterogeneity, mutational analysis and targeted therapies: initial experience with intra-operative Frozen Section Evaluation (FROSE) in bronchoscopic biopsies.

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
backgroundRecent advances in lung cancer treatment have changed the requirement for the amount and quality of biopsy specimens needed to characterize the tumor and select the best treatment. One adjunct to guide the bronchoscopist on the quality and quantity of specimens during bronchoscopic biopsies for the diagnosis of lung cancer is rapid on-site evaluation (ROSE) of cytological specimens. This technique has been shown to add to the diagnostic yield of bronchoscopy when obtaining adequate specimens for molecular profiling in lung cancer. ROSE is not available at all medical centers. We describe our initial experience using intra-procedural Frozen Section Evaluation (FROSE) of bronchoscopic biopsy specimens as an alternative to ROSE.
methodsA retrospective analysis of all interventional pulmonology cases using FROSE between February and July 2015 was performed. Results analyzed to evaluate the success in obtaining adequate specimens for molecular profiling.
resultsA total of 88 interventional pulmonology cases employing a frozen section in at least one site were identified. In 94.3% of cases, a definitive diagnosis of benign or malignant was made. The concordance of frozen section diagnoses of benign or malignant was 100% with final diagnoses. Thirteen of the eighty-eight cases were ultimately sent for molecular analysis. Of these, twelve of thirteen (92.3%) cases were adequate to perform all ordered molecular testing. In all cases there was sufficient tissue to perform EGFR and ALK testing.
conclusionsIn medical centers where ROSE may not be available, the use of FROSE by the local pathologist can be an effective technique to obtain adequate tissue and cytological samples for the diagnosis and molecular profiling of lung cancers. Further prospective study in bronchoscopic tissue sampling techniques to obtain the optimum quantity and quality of samples for molecular profiling of lung cancers for targeted treatments is needed.
