Abstract

Salah satu cara pengobatankanker servik adalah dengan kemoradioterapi melalui pemberian radioterapi dan kemoterapisecara bersamaan pada kanker servik stadium lanjut lokal. Respons kemoradioterapidipengaruhi oleh faktor biologis yaitu kinetika sel yang terdiri dari proliferasi dan kematian sel.Pada penelitian ini dipelajari korelasi antara biomarker proliferasi sel kanker, yaitu AgNOR, MIB-1, dan ekspresi apoptosis jalur caspase-3 dengan respons kemoradioterapi pada kanker servik.Dua puluh satu sediaan mikroskopik jaringan kanker servik yang diambil dari biopsi pasiensebelum menerima tindakan kemoradioterapi diberi pewarnaan AgNOR, sedangkan deteksiMIB-1 dan apoptosis caspase-3 dilakukan dengan teknik immunohistokimia. Setelah selesaimenerima kemoradioterapi dilakukan pengamatan respons klinik dengan cara pelvic control.Hasil penelitian menunjukkan bahwa sebelum kemoradioterapi tidak ditemukan korelasi nilaiAgNOR, MIB-1 dengan apoptosis (p>0,05). Proliferasi sel yang diamati dengan AgNOR danMIB-1 sebelum kemoradioterapi tidak menunjukkan adanya korelasi dengan respons jaringankanker setelah kemoradioterapi, namun ekspresi apoptosis menunjukkan korelasi positifdengan respons kemoradioterapi. Indeks apoptosis caspase-3 yang diperoleh dapat dijadikanbahan pertimbangan pada penjadwalan kemoradioterapi kanker servik.

Abstract

Akt is a protein that is associated with cell proliferation and is expressed at high levels in cancer cells. Some research indicates it may play a role in increasing the resistance of cancer cells to chemotherapy treatment. P53 is a tumor suppressor protein that influences the cell cycle and apoptosis. The purpose of this study was to examine the relationship between the expression of Akt and p53 in cancerous tissue before chemoradiation treatment, and the clinical response to treatment of cervical cancer patients. Twenty microscopic tissue samples were taken from cervical cancer biopsies obtained from patients before cancer treatment. The tissue samples were stained with p53 and Akt antibodies via immunohistochemistry technique, to measure expression of both proteins. After completion of chemoradiotherapy, patients’ clinical response to treatment was determined using the pelvic control method. Our results revealed no correlation between expression of Akt and p53 index (P = 0.74) as well as between p53 Index and chemoradiotherapy clinical response (P=0.29). There was significant correlation between expression of Akt and cervical cancer chemoradiotherapy response (P = 0.03). There was no correlation found between p53 index and chemoradiotherapy clinical response (P = 0.29). High expression of Akt may related with high cell proliferation and resistance to chemoradiotherapy.

Abstract

Proses penentuan nilai dosis radiasi pengion berdasarkan indikator biologis atau biodosimetri umumnya dilakukan berdasarkan analisis kromosom disentrik. Proses biodosimetri berdasarkan analisis kromosom disentrik yang tidak boleh melibatkan kromosom disentrik dalam sel rogue karena nilai dosis yang diperoleh lebih tinggi dari nilai sebenarnya. Sel rogue adalah sel dalam tahap metafase yang berasal dari kultur sel limfosit darah tepi dan memiliki jumlah aberasi kromosom sangat tinggi meskipun sampel darah tidak terpapar oleh radiasi pengion. Hingga kini belum diketahui secara pasti penyebab timbulnya sel rogue dalam sel limfosit darah tepi. Terdapat Didugaan bahwa infeksi virus atau bakteri penyebab terbentuknya sel rogue. Dugaan lainnya menyatakan bahwa paparan radiasi dengan Linear Energy Transfer (LET) tinggi adalah penyebab timbulnya sel rogue. Tujuan penelitian adalah mendeteksi keberadaan sel rogue pada pasien kanker serviks sebelum dan sesudah dilakukan proses kemoradioterapi. Prediksi nilai dosis radioterapi dilakukan berdasarkan jumlah kromosom disentrik dengan atau tanpa melibatkan kromosom disentrik dalam sel rogue. Sebanyak 20 ml sampel limfosit darah tepi dari lima pasien kanker serviks paska radioterapi dikultur, dibuat preparatnya dan diamati. Hasil penelitian menunjukkan adanya satu sel rogue pada salah satu pasien kanker serviks paska kemoradioterap. yang diakibatkan oleh paparan radiasi. Prediksi dosis menunjukkan bahwa nilai prediksi dosis dengan melibatkan kromosom disentrik dalam sel rogue menyebabkan nilai dosis yang diperoleh lebih tinggi dari nilai sebenarnya. Berdasarkan hasil penelitian yang dilakukan dapat disimpulkan bahwa paparan radiasi pengion dapat mengakibatkan terbentuknya sel rogue pada individu dengan tingkat radiosensitivitas tinggi. Dengan demikian proses biodosimetri berdasarkan analisis kromosom disentrik tidak dapat dilakukan dengan melibatkan kromosom disentrik dalam sel rogue. The process of determining the ionizing radiation dose based on biological indicator or biodosimetry is generally carried out using the analysis of dicentric chromosome. Biodosimetry process based on the analysis of dicentric chromosome should not involving the dicentric in a rogue cell that may cause the radiation prediction doses value more higher than the true doses value. Rogue cells is cells in metaphase derived from the peripheral blood lymphocytes culture and contain a high number of chromosome aberration even though the blood sample were not exposed to ionizing radiation. Until now it was not clear what factor that can induce the rogue cells in peripheral blood lymphocytes. There was suggestion that infection of virus or bacteria and radiation exposure of high linear energy transfer (LET) can induce rogue cells. Aim of this research was to detect the presence of rogue cells in cervical cancer patients before and after radio chemotherapy process. The prediction of radiotherapy doses was carried out with and without involving the dicentric chromosomes in the rogue cells. Twenty milliliter of blood samples from five cervical cancer patients obtained before and after radiotherapy was cultured, harvested and analyzed. The experimental result showed that there was a presence of one rogue cell in one cervical cancer patient after radio chemotherapy process. A radiotherapy prediction doses showed that predictive dose value dose involving dicentric chromosomes in rogue cell was higher compared to the real radiation dose value. Based on the research result it can be concluded that exposure to ionizing radiation can induced the presence of the rogue cells in high radiosensitivity person. It means that in the biodosimetry process based on the analysis of dicentric chromosome should not involve the dicentric chromosome in the rogue cell.

Abstract

Kanker servik merupakan penyakit kanker yang umum dijumpai pada wanita yang disebabkan oleh virus HPV (Human Papilova Virus). Tujuan penelitian ini adalah untuk mengetahui hubungan ekspresi protein MNK (Mitogen Activated Protein Kinase) pada penderita kanker serviks sebelum tindakan pengobatan terhadap respon kemoradioterapi. Sampel uji yang digunakan adalah sediaan mikroskopis hasil biopsi jaringan kanker dari penderita kanker serviks stadium lanjut (IIB-IIIB) sebanyak 20 sampel. Metode yang digunakan adalah metode imunohistokimia dengan menggunakan biomarker MNK pada biopsi jaringan kanker serviks. Ekspresi protein MNK yang positif ditandai dengan warna coklat tua yang terdapat pada inti sel. Respon kemoradioterapi diperoleh dari RSUPN Dr. Cipto Mangunkusumo Jakarta dan RS Hasan Sadikin Bandung. Hasil penelitian menunjukkan nilai IRS (Imuno Reaktif Score) protein MNK pada grup respon kemoradioterapi baik lebih tinggi dibandingkan grup respon kemoradioterapi buruk dan tidak ditemukan adanya hubungan IRS protein MNK dengan respon kemoradioterapi. Sedangkan hubungan ekspresi MNK terhadap respon kemoradioterapi menunjukkan adanya korelasi perbedaan grup respon kemoradioterapi antara ekspresi protein MNK negatif dan ekspresi protein MNK positifCervical cancer is a cancer that common in women caused by HPV (Human Papilova Virus).

Sample used was the preparation of microscopic cancer tissue biopsies from patients with advanced cervical cancer (IIB-IIIB) is 20 samples. The method used is immunohistochemistry using MNK biomarkers in cervical cancer tissue biopsies. MNK positive protein expression marked with dark brown color that is contained in the cell nucleus. Chemoradiotherapy response obtained from RSUPN Dr. Cipto Mangunkusumo and Hasan Sadikin Hospital in Bandung. The results show the value of the IRS (Immuno Reactive Score) MNK protein in response to chemoradiotherapy group either higher than the response to chemoradiotherapy group was bad and did not find any relationship IRS MNK protein with chemoradiotherapy response. While the relationship MNK expression responses show a correlation chemoradiotherapy group differences in chemoradiotherapy response between MNK expression negative and MNK expression positive.
