AbstrakKanker payudara triple negative mempunyai prognosis paling buruk. Ki-67, derajat diferensiasi dan invasi limfovaskular (LVI) adalah parameter prognostik patomolekuler, dimana Ki-67 juga dipakai sebagai prediktor respon terapi. Penelitian ini bertujuan untuk mengetahui hubungan derajat diferensiasi dan LVI dengan ekspresi Ki-67 pada kanker payudara tripel negatif. Sembilan belas kasus kanker payudara tripel negatif dikumpulkan dan direview ulang derajat diferensiasi dan LVI. Hasil pemeriksaan Ki-67 dikelompokkan dimana ≤10 % sampai 29 % ekspresi rendah-sedang; dan >30% ekspresi tinggi. Hubungan antara ekspresi Ki-67 dengan derajat diferensiasi dan invasi limfovaskular dianalisis menggunakan Chi Square. Dari 19 kasus kanker payudara tripel negatif, 52,6 % kasus mempunyai derajat diferensiasi tinggi dan sisanya derajat diferensiasi rendah. Invasi limfovaskular ditemukan positif pada 68,4% kasus. Ekspresi Ki-67 yang tinggi hanya ditemukan pada 1 kasus. Uji statistik antara ekspresi Ki-67 dengan derajat diferensiasi maupun dengan invasi limfovaskular tidak ditemukan hubungan yang bermakna. Tidak ditemukan korelasi antara ekspresi Ki-67 dengan derajat diferensiasi dan invasi limfovaskular pada kanker payudara tripel negatif.AbstractTriple negative breast cancer is one of the breast cancer with poorest prognosis. Ki- 67, grade and lymphovascular invasion are the prognostic pathomolecular parameter, and also used as a predictor of response to therapy. The objective of this study was to identify the relationship between Ki-67 expression with grade and lymphovascular invasion in triple negative breast cancer. We found 19 cases of triple negative breast cancer,and performed slide review for grade and lymphovascular invasion. The results of Ki-67 expression were classifiy as low – intermediate ( 30%). We use Chi Square test to assest the relationship between variables. Of 19 triple negative breast cancer cases, 52,6 % of cases were found to have high histopathological grade. Positive lymphovascular invasion was seen in 68,4% cases. Only one case was found with high expression of Ki-67. There were no correlation between Ki-67 expression with histopathological grade and lymphovascular invasion on triple negative breast cancer. There were no significant relationship between Ki-67 expression with grade and lymphovascular invasion on triple negative breast cancer.
