    Abstract
    Background : Breast cancer is a malignant tumor derived from breast epithelial cells (American Cancer Society , 2013) . Over expression of Ki - 67 (a protein found in the nucleus of cells associated with the process of cell proliferation) in breast cancer has been demonstrated good results in patients undergoing chemotherapy and in patients treated with anti- hormonal therapy. Objective : The purpose of this study to determine the degree of correlation between histopathological grading with Ki - 67 expression in breast cancer patients Haji Adam Malik Hospital. Methods : This study uses cross-sectional analytical study is carried out on all breast cancer patients who come in the Division of Surgical Oncology Department of Surgery Haji Adam Malik from 1 January 2011 up to September 2014 were already done histopathological grading examination and Ki - 67 expression by immunohistochemistry. Result : Of the 58 samples studied, the results obtained by the frequency of the highest histopathologic grading 29 grade II ( 50 % ), with low expression of the Ki- 67 protein by 31 patients ( 53.4 % ) and over- expression of the Ki- 67 protein by 27 people ( 46.6 % ). And of the chi square test analysis found samples with over expression of Ki - 67 mostly with histopathological grading Grade II breast cancer as much as 16/29 samples. While samples with low expression of Ki - 67 are mostly located in the histopathological grading of breast cancer Grade I as much as 15/18 samples. Conclusion : conclusion of this study is found a significant correlation between histopathological grading and the expression of Ki - 67 breast cancer.
     
    Latar Belakang : Kanker payudara adalah tumor ganas yang berasal dari sel-sel epitel payudara (American Cancer Society, 2013). Over ekspresi Ki-67 (protein yang ditemukan di dalam inti sel yang berhubungan dengan proses proliferasi sel) pada kanker payudara telah dibuktikan memberikan hasil yang baik pada pasien yang menjalani kemoterapi dan pada pasien yang diobati dengan terapi anti hormonal. Objektif : Tujuan penelitian ini untuk mengetahui tingkat hubungan antara grading histopatologi dengan ekspresi Ki-67 penderita kanker payudara di RSUP Haji Adam Malik. Metode : Penelitian ini menggunakan metode penelitian analitik secara crossectional yang dilakukan pada semua pasien kanker payudara yang datang di Divisi Bedah Onkologi Departemen Ilmu Bedah RSUP Haji Adam Malik dari 1 Januari 2011 sampai dengan September 2014 yang sudah dilakukan pemeriksaan grading histopatologi dan ekspresi Ki-67 dengan imunohistokimia. Hasil : Dari 58 sampel yang diteliti, diperoleh hasil berdasarkan frekuensi grading histopatologi terbanyak 29 orang grade II (50%), dengan low-expression terhadap protein Ki-67 sebanyak 31 pasien (53.4%) dan over-expression terhadap protein Ki-67 sebanyak 27 orang (46.6%). Dan dari uji analisis chi square ditemukan sampel dengan over ekspresi Ki-67 kebanyakan dengan grading histopatologi kanker payudara Grade II sebanyak 16 / 29 sampel. Sedangkan sampel dengan low ekspresi dari Ki-67 kebanyakan berada pada grading histopatologi kanker payudara Grade I sebanyak 15 / 18 sampel. Kesimpulan : Penelitian ini adalah ditemukan terdapat hubungan yang signifikan antara grading histopatologi dan ekspresi Ki-67 kanker payudara.
