[ABSTRAK
Latar Belakang: Kanker kolorektal merupakan tumor ganas ketiga di dunia.Sembilan puluh lima persen kanker kolorektal merupakan adenokarsinoma yangberasal dari lesi prekursor adenoma. Dilaporkan 15%-20% kanker terkait denganinfeksi virus. Virus yang diduga berhubungan dengan kanker kolorektal adalahhuman papilloma virus (HPV) dan tipe tersering adalah 16 dan 18. Hubunganantara HPV dan kanker kolorektal masih menjadi perdebatan. Penelitian inibertujuan untuk mengetahui perbedaan prevalensi infeksi HPV pada adenoma danadenokarsinoma kolorektal di Departemen Patologi Anatomik FKUI/RSCMJakarta dengan menggunakan teknik polymerase chain reaction (PCR). Bahandan Metode: Pemeriksaaan DNA HPV pada 33 kasus adenoma dan 33 kasusadenokarsinoma kolorektal dengan teknik nested PCR MY/GP dan elektroforesis.Pada kasus dengan hasil HPV positif, dilanjutkan PCR menggunakan primerspesifik HPV 16 dan HPV 18. Subjek penelitian berasal dari Departemen PatologiAnatomik FKUI/RSCM. Hasil: Satu dari 33 kasus (3,0%) adenoma dan 3 dari 33kasus (9,1%) adenokarsinoma positif infeksi HPV. Satu kasus adenoma positifHPV bukan merupakan tipe 16 dan 18. Satu kasus adenokarsinoma denganpositif, HPV merupakan tipe 16, 2 kasus merupakan gabungan tipe 16 dan 18.Kesimpulan: Prevalensi infeksi HPV pada adenokarsinoma lebih tinggidibandingkan adenoma kolorektal. Tipe HPV pada kasus adenokarsinomakolorektal merupakan tipe 16 dan 18.

ABSTRACT
Background : Colorectal cancer is the third malignant tumor in the world.Ninety-five percent of colorectal cancers are adenocarcinomas derived fromprecursor lesions adenoma. There are 15% -20% of cancers associated with viralinfections. Virus are suspected associated with colorectal cancer is the humanpapilloma virus (HPV) and the most common types are 16 and 18. Therelationship between HPV and colorectal cancer is still being debated. This studypurpose to determine the prevalence differences of HPV infection in colorectaladenomas and adenocarcinomas in the Department of Anatomic Pathology,FKUI/RSCM Jakarta by using the polymerase chain reaction (PCR). Materialsand Methods : HPV DNA examination on 33 cases of adenoma and 33 cases ofcolorectal adenocarcinoma by nested MY/GP PCR technique and electrophoresis.In the cases with positive HPV results, continue by specific primers HPV 16 andHPV 18 PCR. The subject of the study came from the Department of AnatomicPathology, FKUI/RSCM. Result : One (3.0%) adenomas and 3 (9.1%)adenocarcinoma from 33 cases adenoma and adenocarcinoma are HPV positive.One case of HPV positive adenomas are not types 16 and 18. HPV positiveadenocarcinoma, 1 case was type 16, two cases are combination of types 16 and18. Conclusion : The HPV prevalence in adenocarcinoma was higher thancolorectal adenoma. HPV types on positive colorectal adenocarcinoma cases aretypes 16 and 18., Background : Colorectal cancer is the third malignant tumor in the world.Ninety-five percent of colorectal cancers are adenocarcinomas derived fromprecursor lesions adenoma.
