Purpose: The purpose of this study was to evaluate the feasibility and specimen quality of lymph node biopsies prepared through a novel automated system for automated fixation, drying and staining compared to standard slide preparation method. Methods: We performed a prospective, single-center study of patients undergoing endobronchial ultrasound. Samples were split into conventional standard of care (SOC) slide preparation and preparation using the device (ASP). Pathologists compared the SOC slides to the slides prepared by the automated system and assessed the following metrics: nuclear and cytoplasmic quality, presence of debris/artifact, staining quality, creation of a monolayer, and ease of adequacy/diagnosis assessment. A score between 1 (lowest quality) and 3 (highest quality) was assigned to the above metrics. Results: 60 patients were recruited. One to three lymph nodes were sampled for each patient with a total of 73 samples collected. The mean scores of each assessment category showed no statistical difference between the two preparation techniques except for improved monolayer creation in the ASP samples. All samples showed diagnostic equivalency between the automated slides and conventional slides except for one which was reported to be suspicious on the ASP sample and atypical on the SOC. Conclusion: Study results suggest that slides prepared by the automated system are of adequate quality for adequacy assessment with diagnostic concordance when compared to SOC slides. |
