Utility of rapid on-site evaluation in rarely performed splenic tissue biopsies
1Department of Pathology, Roswell Park Comprehensive Cancer Center, Buffalo New York.
Introduction:
Diagnosing benign and malignant splenic lesions on cytology or small biopsies can be challenging due to limited tissue sampling, despite advancements in image modalities and biopsy techniques. This study aimed to assess the effectiveness of rapid on-site evaluation (ROSE) during splenic core needle biopsies (CNBs) in ensuring adequate tissue collection for accurate diagnosis.
Materials And Methods:
In this retrospective study, all cases of splenic CNBs with available ROSE were searched in the pathology database from 2012 to 2022. The interpretations of ROSE were compared to the final CNB diagnoses. Concordance and discordance rates were calculated accordingly.
Results:
A total of 50 cases were identified. At ROSE, 90% (45/50) of cases were deemed as adequate and 10% (5/50) as inadequate. The final CNB tissues were diagnostic in 94% (41/50) of cases and were nondiagnostic in 9% of cases. The concordance rate between ROSE and final CNB diagnoses was 80%.
Conclusions:
ROSE is a valuable tool for optimizing tissue sampling during splenic CNBs, thereby improving diagnostic accuracy with splenic lesions.
