    Abstract
    Introduction : Breast cancer (BC) is a major problem in the developed countries and developing countries around the world. The incidence recorded a low and a high mortality occurs in developing countries. This is due to the limited health system and the low level of awareness that most women with breast cancer is diagnosed at late stage. Data from the World Health Organization estimated 1.67 million new cancer cases occurred in 2012 (25% of all cancers). Meanwhile, the figure of 522,000 deaths from BC and almost 62% of cases occur in developing countries. Material and Method : This study is a retrospective descriptive study to look at the pattern of expression of Ki-67 in luminal A and luminal B breast cancer patients. The research was conducted at the Division of Surgical Oncology FK USU H. Adam Malik Hospital and Anatomy Pathology Department of H. Adam Malik Hospital Medan. Result : Immunohistochemical picture type of luminal A and B breast cancer patients in the Haji Adam Malik Hospital shows that have HER2 expression as much as 16 (24.6%) and high expression of Ki-67 as much as 16 (24.6%). In BC patients type luminal A and B in this study found high expression of Ki-67 as many as 16 patients (24.6%), whereas 49 patients (75.4%) with a low expression of Ki-67. Conclusion : Dual positive hormonal receptor (ER + / PR +) is the largest with 33 patients (50.8%) followed by hormonal receptor ER + / PR - 21 cases (32.3%). BC in Patients with luminal A common expression of Ki-67 with a low total of 37 cases (56.9%), patients with luminal B BC Ki-67 expression was found higher by 16 cases (24.6%) and Ki-67 low expression 12 cases (18.5%). Her2 positive and high expression of Ki-67 only 4 cases, while patients with low expression of Her2 negative and Ki-67 as many as 37 cases.
     
    Pendahuluan: Kanker payudara (KPD) merupakan masalah utama pada negara maju maupun Negara berkembang di seluruh dunia. Angka kejadian yang tercatat rendah serta kematian yang tinggi terjadi pada negara-negara sedang berkembang. Hal ini disebabkan sistem kesehatan yang terbatas serta rendahnya kesadaran sehingga sebagian besar wanita dengan KPD didiagnosis pada stadium akhir. Data dari World Health Organization diperkirakan 1,67 juta kasus kanker baru terjadi pada tahun 2012 (25% dari seluruh kanker). Sedangkan angka kematian akibat KPD sebesar 522.000 kasus dan hampir 62% terjadi pada Negara-negara sedang berkembang. Material dan Metode : Penelitian ini merupakan penelitian retrospektif deskriptif untuk melihat pola ekspresi dari Ki- 67 pada pasien KPD luminal A dan luminal B. Penelitian ini dilakukan di divisi Bedah Onkologi FK USU RSUP H. Adam Malik dan bagian Patologi Anatomi RSUP H. Adam Malik Medan. Hasil: Gambaran imunohistokimia pasien kanker payudara tipe luminal A dan B di RSUP HAM menunjukkan yang memiliki ekspresi HER2 sebanyak 16 (24,6%) dan ekspresi tinggi Ki-67 sebanyak 16 (24,6%). Pada pasien KPD tipe luminal A dan B pada penelitian ini didapati ekspresi tinggi Ki-67 yaitu sebanyak 16 pasien (24,6%), sedangkan sebanyak 49 pasien (75,4%) dengan ekspresi rendah Ki-67. Kesimpulan: Reseptor hormonal positif ganda (ER+/PR+) merupakan yang terbanyak dengan 33 pasien (50,8%) diikuti dengan reseptor hormonal ER+/PR - 21 kasus (32,3%). Pada Pasien KPD luminal A dijumpai Ki-67 dengan ekspresi rendah sebanyak 37 kasus (56,9%), pasien KPD luminal B dijumpai Ki-67 ekspresi tinggi sebanyak 16 kasus (24,6%) dan Ki-67 ekperesi rendah sebanyak 12 kasus (18,5%). Her2 positif dan ekspresi tinggi Ki-67 hanya 4 kasus, sedangkan pasien dengan Her2 negatif dan ekspresi rendah Ki-67 sebanyak 37 kasus.
