    Abstract
    BACKGROUND: The histologically distinction between adenocarcinoma derived from the endometrium from the cervix may be difficult, especially on small biopsy or curettage specimens. Where the growth of tumors derived, whether from endometrial or endocervical, often become a problem, while in the therapeutic and prognostic aspects there is a difference between the origin of the cancer. Examination that allows to identify the origin of tissue is immunohistochemistry which immunohistochemical examination is more accurate compared with hematoxylin-eosin examination alone. OBJECTIVE: To determine the expression of vimentin in endometrial and cervical adenocarcinoma in the Department of Obstetrics and Gynecology, Faculty of Medicine USU. METHODS: The study of diagnostic test with examination of vimentin sensitivity and specificity outcome on paraffin tissue blocks endometrial adenocarcinoma and adenocarcinoma of the cervix after surgery (total hysterectomy or radical hysterectomy), curettage and biopsy in the Department of Obstetrics and Gynecology RSUP H. Adam Malik and RSUD dr. Pirngadi Medan. RESULTS: The expression of vimentin as a marker in endometrial adenocarcinoma has a value of 96.3% sensitivity and 81.8% specificity. From these data calculations were also found positive predictive value of 81.2% and negative predictive value of 96.4%. There is an inverse correlation with the weak force between assessment vimentin staining with endometrial adenocarcinoma differentiation with r = -0.394. CONCLUSION: Examination of vimentin expression specific to endometrial adenocarcinoma. The higher the value of vimentin staining, the better differentiated endometrial adenocarcinoma (p <0.05).
     
    LATAR BELAKANG : Pembedaan secara histologik antara adenokarsinoma yang berasal dari endometrium dengan yang berasal dari serviks mungkin sulit, terutama pada biopsi kecil atau spesimen kuretase. Darimana pertumbuhan tumor berasal, apakah dari endometrium atau endoserviks, sering menjadi permasalahan, sementara dalam aspek terapi dan prognostik terdapat perbedaan antara kedua asal kanker tersebut. Pemeriksaan yang memungkinkan mengidentifikasi asal jaringan tersebut adalah imunohistokimia dimana pemeriksaan imunohistokimia ini lebih akurat dibandingkan dengan pemeriksaan hematoksilin-eosin saja. TUJUAN: Mengetahui ekspresi vimentin pada adenokarsinoma endometrium dan serviks di Departemen Obstetri dan Ginekologi FK USU. METODE : Penelitian uji diagnostik dengan luaran sensitivitas dan spesifisitas pemeriksaan vimentin terhadap blok parafin jaringan adenokarsinoma endometrium dan adenokarsinoma serviks pasca pembedahan (histerektomi total ataupun radikal histerektomi), kuretase dan biopsi di Departemen Obstetri dan Ginekologi RSUP. H. Adam Malik Medan dan RSUD dr. Pirngadi Medan. HASIL : Ekspresi vimentin sebagai petanda pada adenokarsinoma endometrium memiliki nilai sensitivitas 96,3% dan spesifisitas 81,8%. Dari perhitungan data tersebut juga didapati nilai duga positif pemeriksaan vimentin sebesar 81,2% dan nilai duga negatif sebesar 96,4%. Terdapat korelasi terbalik dengan kekuatan yang lemah antara penilaian pewarnaan vimentin dengan diferensiasi adenokarsinoma endometrium dengan nilai r= -0,394. KESIMPULAN : Pemeriksaan ekspresi vimentin spesifik terhadap adenokarsinoma endometrium. Semakin tinggi nilai pewarnaan vimentin, maka semakin baik diferensiasi adenokarsinoma endometrium (p<0,05).
