| Outline of Final Research Achievements |
Fine-needle aspiration biopsy (FNAB), an important diagnostic tool given its simplicity, safety, and cost-effectiveness, is fast becoming a popular procedure in the diagnosis of thyroid tumors.
Liquid-based cytology (LBC), in which isolated cells are collected in a fixative solution or RNA extraction solution directly, is advantageous in that it facilitates the preparation of homogenous cytological specimens. However, LBC has not been applied to molecular diagnoses, such as RNA expression-based diagnosis, mainly because of difficulties in cell recovery and RNA isolation.
We performed this study to improve cell recovery and RNA extraction from thyroid tumor cell samples processed for LBC, by which the transcriptome analysis-based identification of pre-operative biomarkers is expected.
