[RA-03] Lobolar neoplasm: how to define and diagnose?
The term "lobolar neoplasia (LN)" is defined by the WHO Classification of Breast Tumour, 5th edition, 2019 as the entire spectrum of atypical epithelial lesions originating in the terminal duct lobolar unit and characterised by a proliferation of generally small, non-cohesive monomorphic cells, with or without pagetoid involvement of terminal ducts. Atypical lobolar neoplasia (ALH) and lobolar carcinoma in situ (LCIS) are separated by the extension of the disease. ...
[OA-27] A study of tumour-infiltrating lymphocyte in distal cholangiocarcinoma
Cholangiocarcinoma (CCA) is one of major cancer in Northeast Thailand. Studies reveal tumours can induce immune response due to their altered protein products recognised as foreign bodies by the immune system. Tumour-infiltrating lymphocytes (TILs) can be assessed to represent the mentioned immune response. Recently, TILs are a potential predictive factor of prognosis in many solid tumours; still, data researched in CCA are limited. This study aimed to assess TILs in distal cholangiocarcinoma according to The International TILs Working Group (ITWG) guideline and to correlate it with...
