"Latar Belakang. Kesintasan 3 tahun pasien KNF stadium lokal lanjut di Indonesia lebih rendah dibandingkan luar negeri. Prediktor alternatif dari rasio hemoglobin-trombosit (RHT) lebih sederhana, murah, dan stabil nilainya dibanding rasio dari komponen sel leukosit, namun belum ada studi yang meneliti perannya dalam memrediksi mortalitas tiga tahun pasien KNF stadium ini.Tujuan. Mengetahui peran RHT sebelum terapi dalam memrediksi kesintasan tiga tahun pasien KNF stadium lokal lanjut.Metode. Studi kohort retrospektif yang meneliti 289 pasien KNF stadium lokal lanjut yang diterapi di Rumah Sakit Cipto Mangunkusumo (RSCM) dalam rentang waktu Januari 2012 - Oktober 2016. Nilai RHT optimal didapatkan menggunakan receiver operating curve (ROC). Subjek penelitian dibagi menjadi 2 kelompok, di bawah dan di atas titik potong. Kurva Kaplan-Meier digunakan untuk menilai kesintasan tiga tahun dan dilakukan uji regresi Cox sebagai uji multivariat terhadap variabel perancu (usia > 60 tahun, stadium, jenis kelamin, dan indeks massa tubuh) untuk mendapatkan nilai adjusted hazard ratio (HR).Hasil. Nilai titik potong RHT optimal adalah 0,362 (AUC 0,6228, interval kepercayaan (IK) 95% : 0,56-0,69, sensitivitas 61,27%, spesifisitas 60,34%). 48,44% pasien memiliki nilai RHT <0,362 dan memiliki mortalitas tiga tahun lebih besar dibandingkan kelompok lainnya (50%vs31,54%). RHT < 0,362 secara signifikan memrediksi kesintasan tiga tahun (p = 0,003; HR 1,75; IK 95% 1,2-2,55). Pada analisis multivariat, RHT < 0,362 sebelum terapi merupakan faktor independen dalam memrediksi kesintasan tiga tahun pada pasien KNF stadium lokal lanjut (adjusted HR 1,82; IK 95% 1,25-2,65).Simpulan. RHT < 0,362 sebelum terapi dapat memrediksi kesintasan tiga tahun pasien KNF stadium lokal lanjut

Background. The 3-year survival of locally advanced nasopharyngeal cancer (NPC) patients in Indonesia is lower than in foreign countries. Alternative predictors from the hemoglobin-platelet ratio (HPR) are easier, cheaper, and stable in value than the ratio of leukocyte cell components, but there are no study conducted to know its potential in predicting three-year survival in locally advanced

nasopharyngeal cancer.

Objective. To determine the role of pre-treatment hemoglobin to platelet ratio in predicting three-year survival of locally advanced nasopharyngeal cancer patients.

Method. Retrospective cohort study that examined 289 locally advanced NPC patients who underwent therapy at the National Government General Hospital-Cipto Mangunkusumo from January 2012 to October 2016. HPR cut-off was determined using ROC, and then subjects were divided into two groups according to its HPR value. The Kaplan-Meier curve was used to determine the three-year survival of the patients and cox regression test used as multivariate analysis with confounding variables in order to get adjusted hazard ratio (HR).

Results. The optimal cut-off for HPR was 0,362 (AUC 0,6228, 95% CI: 0,56-0,69, sensitivity 61,27%, specificity 60,34%). Patients with HPR < 0,362 occurred in 48, 44% and had higher three-year mortality (50% vs. 31, 54%). HPR <0.362 significantly predicted the three years of survival (p = 0,003; HR 1, 75; IK 95% 1, 2-2, 55). In multivariate analysis,

it was concluded that pre-treatment HPR < 0,362 was an independent factor in predicting three-year

survival in locally advanced NPC patients (adjusted HR 1, 82; IK 95% 1, 25-2, 65).

Conclusion. Pre-treatment HPR < 0, 362 could predict the three-year survival of locally advanced nasopharyngeal cancer patients."

"Latar Belakang: Karsinoma narofaring (KNF) termasuk kanker dengan prevalensi yang cukup tinggi di Indonesia dengan prognosis yang cukup. Dalam menentukan progresifitas suatu kanker, didapatkan peranan penting dari penurunan tumor supresor gen dan peningkatan proliferasi. Hal tersebut ditandai oleh marker p53 sebagai gen supresor yang menginduksi apoptosis dan Ki67 sebagai marker proliferasi sel. Hingga saat ini belum terdapat penelitian mengenai hubungan overekspresi p53 dan Ki67 terhadap respon kemoradiasi dan analisis kesintasan selama 3 tahun pada KNF stadium lokal lanjut. Tujuan: Mencari hubungan antara overekspresi p53 dan Ki67 terhadap respon kemoradiasi dan kesintasan 3 tahun pasien KNF stadium lokal lanjut. Metode: Penelitian ini merupakan penelitian analitik observasional dengan desain analisis kesintasan. Penelitian ini menggunakan desain penelitian kohort retrospektif, dengan pengambilan data dari rekam medis kemudian ditelusuri riwayat perjalanan penyakitnya. Sample penelitian berupa jaringan pada blok parafin pasien KNF stadium lokal lanjut yang diambil secara consecutive sampling dari populasi penelitian dari periode 2015–2017 di RSUPN Dr. Cipto Mangunkusumo sejumlah 82 orang. Hasil: Dari total 82 pasien KNF stadium local lanjut, terdapat 65 pasien kelamin laki – laki (79,3%) dan 17 pasien perempuan (20,7%), dengan usia paling banyak pada kelompok 41 – 50 tahun sebanyak 31,8%. Overekspresi p53 ditemukan pada 36 pasien (43,9%), sementara overekspresi Ki67 ditemukan pada 35 pasien (42,7%). Dari respon kemoradiasi, pasien dengan overekspresi p53 dan Ki67 berpeluang memberikan respon negatif yang lebih tinggi dibandingkan dengan low ekspresi (RR = 3,052 dengan IK95%: 1,777 – 5,242, p = 0,009; RR = 2,573 dengan IK95%: 1,547 – 4,297, p = 0,002 berturut-turut). Dinilai dari kesintasan 3 tahun, pasien dengan overekspresi p53 memiliki kesintasan 3 tahun yang lebih buruk dibandingkan dengan low ekspresi (HR = 19,827 dengan IK95%: 5,974 – 65,798, p = <0,001). Begitu juga dengan overekspresi Ki67 memiliki kesintasan 3 tahun yang lebih rendah.

Background: Naropharyngeal carcinoma (NPC) is a cancer with a fairly high prevalence in Indonesia with a fairly poor prognosis. Tumor supressor gene and cancer proliferation played an important roles in determining the progression of a cancer. This was indicated by the marker p53 as a suppressor gene that induces apoptosis and Ki67 as a marker of cell proliferation. There has been limited research on the relationship of p53 and Ki67 overexpression to the chemoradiation response and 3-year survival in locally advanced NPC. Objective: To determine the relationship between p53 and Ki67 overexpression with chemoradiation response to therapy and 3-year survival in locally advanced NPC patients. Methods: This research is an observational analytic study with a survival analysis design. This study used a retrospective cohort study design, by collecting data from medical records and then tracing the history of the disease. The research sample was tissue in the paraffin block of locally advanced NPC patients taken by consecutive sampling from the study population from period 2015–2017 at Dr. Cipto Mangunkusumo National Hospital with a total number of 82 patients.

Results: From a total of 82 patients with locally advanced NPC, there were 65 male patients (79.3%) and 17 female patients (20.7%), with the most age being in the 41-50 years group as many as 31.8 %. Overexpression of p53 was found in 36 patients (43.9%), while overexpression of Ki67 was found in 35 patients (42.7%). Based on therapy response, patients with overexpression of p53 and Ki67 had a higher chance of giving a negative response compared to those with low expression (RR = 3,052 with IK95%: 1,777 – 5,242, p = 0,009; RR = 2,573 with IK95%: 1,547 – 4,297, p = 0,002 respectively). Assessed by 3- year survival, patients with p53 overexpression were statistically significantly worse than those with low-expression (HR = 19,827 with IK95%: 5,974 – 65,798, p = <0,001). Likewise, Ki67 overexpression was statistically significant and had a lower 3-year survival compared to low Ki67 expression (HR = 14,634 with IK95%: 5,074 – 42,204, p = <0,001). Conclusion: Locally advanced NPC patients with p53 overexpression and Ki67 overexpression have a tendency to give a negative chemoradiation response and have a lower 3-year survival."
