    Abstract
    Latar belakang: TNBC merupakan kanker payudara yang heterogen. Dengan menggunakan pewarnaan imunohistokimia, TNBC dapat dibagi menjadi sub-tipe stem cell-like, basal, baso-luminal, luminal, IFN-αIIRich, dan IGF-1RHigh. Metode: Penelitian deskriptif dengan pendekatan cross sectional ini dilakukan di Laboratorium Patologi Anatomik Departemen Patologi Anatomik/RSUP Haji Adam Malik Medan dan Departemen Bedah Onkologi RSUP Haji Adam Malik Medan untuk mengklasifikasi sub-tipe TNBC dengan menggunakan pemeriksaan panel imunohistokimia dan menilai bagaimana distribusi sub-tipe TNBC berdasarkan histologic grading. Hasil: Pewarnaan menggunakan panel imunohistokimia CD44, CD24, Twist, Claudin-7, CK5, CK8/18, EMA, IFN-αII, IGF-1R, E-Cadherin, dan Ki67 terhadap 67 kasus TNBC menunjukan hasil yang sangat heterogen dan overlapping. Hasilnya diklasifikasikan menjadi sub-tipe stem cell-like 7 kasus (10,5%), pre-basal 2 kasus (3%), basal 1 kasus (1,5%), baso-luminal 22 kasus (33%), stemo-luminal 2 kasus (3%), dan luminal 21 kasus (31%). Sub-tipe stem cell-like terbagi atas SC-1Low (SC-1L) 2 kasus, SC-2Low (SC-2L) 3 kasus, serta SC-3Low (SC-3L) dan SC-3High (SC-3L) masing-masing 1 kasus. Kesimpulan: Identifikasi stem-cells pada TNBC menjadi perhatian khusus. Dalam mengklasifikasikan sub-tipe TNBC, sub-tipe stem cell-like dapat digunakan CD44, CD24, Twist, untuk basal dengan CK5, baso-luminal dengan CK5 dan CK8/18, dan CK8/18 untuk luminal.
     
    Background: TNBC is a heterogenous breast cancer. By using immunohistochemistry staining, TNBC can be differentiated into stem cell-like, basal, baso-luminal, luminal, IFN-αIIRich, and IGF-1RHigh subtypes. Method: This descriptive cross-sectional study was carried out in Haji Adam Malik Hospital/Department of Anatomical Pathology, Medical Faculty USU Medan and Department of Oncology/Surgical Haji Adam Malik Hospital Medan from March to October 2017 to classify subtypes of TNBC by immunohistochemistry stained and also to identify how the distribution of TNBC subtypes based on histologic grading. Results: By using an immunohistochemistry staining panel of CD44, CD24, Twist, Claudin-7, CK5, CK8/18, EMA, IFN-αII, IGF-1R, E-Cadherin, and Ki67, a total of 67 cases TNBC showed marked heterogenous and overlapping profiles.They was classified as 7 cases of stem cell-like sub-types (1.5%), 2 cases of pre-basal (3%), 1 case of basal (1.5%), 22 cases of baso-luminal (33%), 2 cases stemo-luminal (3%), and 21 cases of luminal(31&). Stem cell-like sub-types consisted of 2 cases SC-1Low (SC-1L), 3 cases SC-2Low (SC-2L), 1 case SC-3Low (SC-3L) and 1 case SC-3High (SC-3L).
