Abstract

Latar belakangKarsinoma payudara invasif merupakan suatu keganasan epitelial payudara yang ditandai oleh invasi sel-selepitel ke dalam stroma. Secara global, insidensi karsinoma payudara invasif menduduki peringkat tertinggi danterus meningkat dari tahun ke tahun. Pada jaringan payudara normal, ekspresi CD-10 terlokalisir pada sel-selmioepitel dan tidak teridentifikasi pada stroma. Demikian juga, pada ductal carcinoma in situ (DCIS), CD-10tidak terekspresi pada stroma. Namun pada karsinoma payudara invasif CD-10 akan terekspresi pada stroma.CD-10 merupakan suatu cell-surface zinc-dependent metalloproteinase yang sering direkomendasikan sebagaimarker leukemia limfoblastik. Beberapa penelitian telah dilakukan untuk menilai hubungan antara ekspresi CD10 dan grading histopatologi karsinoma payudara invasif, namun sampai kini hasilnya masih kontroversi.Tujuan penelitian ini untuk menganalisis hubungan antara ekspresi imunohistokimia CD-10 dan gradinghistopatologi karsinoma payudara invasif.MetodePenelitian ini merupakan penelitian deskriptif analitik dengan pendekatan cross sectional. Sampel penelitianadalah blok parafin, berasal dari jaringan payudara yang didiagnosis secara histopatologi sebagai karsinomapayudara invasif. Sampel dipulas dengan teknik immunohistokimia menggunakan CD-10; dan kemudianekspresi CD-10 dianalisis dengan uji Kruskal-Wallis.HasilBerdasarkan analisa statistik Kruskal-Wallis terhadap 60 sampel kasus karsinoma payudara invasif mengujihubungan ekspresi imunohistokimia CD-10 dengan grading histopatologi karsinoma payudara invasif, diperolehp-value=0,0001 (p<0,05).KesimpulanEkspres

Abstract

BackgroundProstate cancer is the second most common cancer and fifth most common cancer cause of death in males. Tissue biopsy is a goldstandard examination to diagnose prostate cancer. One of the hallmarks of cancer is increased activity of cell proliferation. Thisactivity can be detected with Ki-67 and AgNOR (Argyrophilic nucleolar organizing region). The aim of this study is to analyzedcorrelation between AgNOR and Ki-67 expression in grading of prostated adenocarcinoma.MethodsThis analytic cross-sectional study was held in Laboratory of Anatomical Pathology of Medical Faculty of USU/ RSUP H. AdamMalik Medan. Thirty paraffin blocks diagnosed with prostate adenocarcinoma were stained with H&E and p63 immunohistochemistrythen evaluated based on Gleason’s histopathological grading and stained with Agnor and Ki 67.ResultsAgNOR expression yang diperoleh pada grading adenokarsinoma prostat group 1, 2, 3, 4, dan 5 berturut-turut adalah 43; 32,40(±14,54); 64,29 (±28,2); 59,5 (±28,32); 69,22 (±29,26). Ekspresi Ki-67 pada setiap grading adenokarsinoma prostat group 1, 2, 3, 4,dan 5 secara berurutan adalah 43; 32,4 (±14,53); 64,29 (±28,2), 59,5 (±28,31); 69,22 (±29,26). Statistical analyses showed thatthere was no significantly correlation between grading of prostate adenocarcinoma and AgNOR expression (p=0.065), and Ki-67expression (p=0.18). Nevertheless, a significantly correlation between KI-67 expression and grading of prostate adenocarcinomawas found (p=0.34).ConclusionKi-67 could be used as prognostic indicator for prostate adenocarcinoma.
