[OA-28] The Milan system for reporting salivary gland cytopathology: a 7-year retrospective institutional study

Fine needle aspiration (FNA) cytology is efficient in guiding salivary gland lesions management. Lack of standardised reporting complicates communication between pathologists and clinicians. The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) has been proposed to improve reporting uniformity. This study aimed to reclassify salivary gland FNA and evaluate risk of malignancy (ROM) in each diagnostic category. All salivary gland FNA cytology in Srinagarind Hospital from January 2013 to December 2019...

[OA-23] Tropomyosin receptor kinase protein expression in Thai cholangiocarcinoma: clinicopathological correlation, pattern expression and prognosis

Tropomyosin receptor kinase (TRK) gene fusion has been found in associated with many tumours and coold be targeted treatment. Immunohistochemistry (IHC) expression of TRK is widely used to screening this alternation. The aim of this study was to investigate the expression of TRK protein detected by IHC in Thai cholangiocarcinoma (CCA) and to correlate with clinicopathological and survival data. Retrospective study of CCA patients who diagnosed from January 2011 to December 2015. ...
