"Kanker nasofaring (KNF) merupakan kanker leher kepala terbanyak di Indonesia (28,4%) dan sebagian besar terdiagnosis pada stadium lanjut. Modalitas pengobatan pada kasus KNF stadium lanjut adalah kemoterapi dan radioterapi. Namun, pada stadium sama, respon terhadap pengobatan memiliki hasil berbeda dikarenakan adanya perbedaan karakteristik biologi molekular. Cyclin D1 adalah protein yang berperan dalam siklus sel. Peningkatan ekspresi cyclin D1 akan mempercepat proliferasi. Penelitian ini ingin mengetaui tingkat ekspresi cyclin D1 terhadap respons kemoterapi. Hal tersebut berdasarkan perbedaan hasil penelitian terdahulu. Data ekspresi cyclin D1 pada KNF di Indonesia belum ada, sehingga perlu penelitian ekspresi cyclin D1 pada KNF serta hubungannya berdasarkan respons pengobatan. Metode: Penelitian ini menggunakan studi kohort retrospektif dengan subjek merupakan pasien KNF yang berobat di RSCM pada kurun waktu 2015-2018. Gambaran radiologi sebelum dan sesudah pengobatan ditinjau ulang berdasarkan kriteria RECIST. Pewarnaan imunohistokimmia cyclin D1 menggunakan antibodi monoklonal cyclin D1 NovocastraTM dengan teknik pengambilan antigen suhu tinggi dan intensitasnya dinilai dengan H-skor menurut kriteria Allred. Hasil: Terdapat 16 subjek (51,6%) dengan ekspresi cyclin D1 positif dan 15 subjek (48,4%) dengan ekspresi negatif. Peneliti menemukan bahwa ekspresi cyclin memiliki perbedaan rerata yang bermakna antara kelompok subjek yang respons (rerata 116,24 ± 57,80) dan tidak respons (rerata 77,97 ± 45,27) terhadap pengobatan (p = 0,048). Simpulan: Penelitian ini menunjukkan ekspresi cyclin D1 yang kuat pada kelompok dengan respons pengobatan yang baik.

Nasopharyngeal cancer (NPC) is the most type of head and neck cancer in Indonesia (28.4%) and mostly diagnosed at advanced stage. Treatment of this stage is chemotherapy and radiotherapy. However, patients with the same stage of disease had different treatment response probably due to different characteristics of molecular biology. Cyclin D1 is a protein involved in cell cycle, which the overexpression of it will fasten proliferation. Studies regarding the association of cyclin D1 expression and chemotherapy response have shown a different result. In Indonesia, data of cyclin D1 expression of NPC do not yet exist. This study aimed to examine the proportion of cyclin D1 in NPC and its association with treatment response. Methods: A retrospective cohort study was conducted using subjects of NPC patients at Cipto Mangunkusumo Hospital from 2015 until 2018. The response of treatment was reviewed based on RECIST criteria. The technique used for cyclin D1 immunohistochemistry staining was antigen retrieval methods, using cyclin D1 NovocastraTM monoclonal antibody and the intensity was assessed based on Allred criteria. Results: Sixteen subjects (51.6%) had positive expression of cyclin D1 and 15 subjects (48.4%) had negative expression. The researchers found that cyclin D1 expression had significant mean differences between groups of subjects who responded (mean ± SD = 116.24 ± 57.80) and did not respond (mean ± SD = 77.97 ± 45.27) to treatment (p = 0.048). Conclusion: This study suggests that higher expression of cyclin D1 is associated with a good treatment response in NPC patients."

"Latar Belakang: Leukemia Granulositik Kronik (LGK) fase kronik merupakan salah satu penyakit keganasan hematologi yang diagnosis definitifnya ditegakkan menggunakan pemeriksaan baku emas sitogenetika untuk mendeteksi Kromosom Philadelphia dan/ atau Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) BCR-ABL untuk mendeteksi transkrip gen BCR-ABL. Berdasarkan pengamatan, pasien-pasien LGK fase kronik di Poliklinik Hematologi-Onkologi Medik Departemen Ilmu Penyakit Dalam RSUPN dr. Cipto Mangunkusumo yang telah menjalani pemeriksaan sitogenetika dan/ atau RT-PCR BCR-ABL akan menunjukkan: LGK Ph (+)/ BCR-ABL (+) dan LGK bentuk kelainan Ph/ BCR-ABL lainnya. Tujuan: Mengetahui gambaran klinis dan laboratorium hematologis LGK fase kronik, proporsi LGK Ph(+)/BCR-ABL(+), serta bagaimana perbandingan dan hubungan gambaran klinis dan laboratorium hematologis antara LGK Ph (+)/ BCR-ABL (+) dengan LGK bentuk kelainan Ph/ BCR-ABL lainnya. Metode: Studi potong lintang. Sampel penelitian diambil dengan metode consecutive. Analisis menggunakan uji Chi-square dan regresi logistik. Hubungan antar variabel dinyatakan bermakna apabila nilai p<0,05. Hasil: Dari 80 subjek LGK fase kronik: rerata usia 39,4 ± 13,1 tahun. Perbandingan pria : wanita = 1 : 1. Keluhan subjek yang simtomatik : asimtomatik = 83,8% : 16,2%. Keluhan yang simtomatik adalah: perut bengkak, lemas, begah, keringat malam, dan benjolan di perut. Pemeriksaan fisik splenomegali : limpa tidak teraba = 83,8% : 16,2%. Pemeriksaan laboratorium hematologis menunjukkan: rerata kadar Hb adalah 10,6 ± 1,7 g/dL, median jumlah leukosit adalah 125.710 /uL, dan median jumlah trombosit adalah 470.000/uL. Proporsi LGK Ph (+)/ BCR-ABL (+) mencapai 90%. Perbandingan gambaran klinis dan laboratorium hematologis antara LGK Ph (+)/ BCR-ABL (+) dan LGK bentuk kelainan Ph/ BCR-ABL lainnya adalah sebagai berikut: keluhan yang simtomatik 80,6% : 100 %, Splenomegali 82% : 92,3%, Median Hb 10,3 g/dL : 10,3 g/dL, Median leukosit 124.620 : 127.050, Median Trombosit 455.000 : 487.000. Hasil analisis bivariat dan multivariat menunjukkan tidak ada variabel gambaran klinis dan laboratorium hematologis yang berhubungan bermakna antara LGK Ph (+)/ BCR-ABL (+) dengan LGK bentuk kelainan Ph/ BCR-ABL lainnya. Kesimpulan: Tidak ada variabel gambaran klinis dan laboratorium hematologis yang berhubungan bermakna antara LGK Ph(+)/ BCR-ABL(+) dengan LGK bentuk kelainan Ph/ BCR-ABL lainnya.

Background: Chronic myeloid leukemia (CML) is one of hematological malignancy in which the gold standard of definitive diagnosis is established by cytogenetic to detect Philadelphia chromosome and Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) to detect the BCR-ABL gene transcript. Based on observation, patients with chronic phase CML at policlinic Hematology-Medical Oncology Department of Internal Medicine dr. Cipto Mangunkusumo National Hospital who have been performed cytogenetic and RT-PCR BCR-ABL examination showed: Ph (+)/ BCR-ABL (+) CML and other type of Ph/ BCR-ABL CML.

Aims: To recognize the clinical features and hematological laboratories of chronic phase CML, the proportion of Ph (+)/ BCR-ABL (+) CML, and comparison & association of clinical features and hematological laboratories between Ph (+)/ BCR-ABL (+) CML and other type of Ph/ BCR-ABL CML.

Method: This is a cross-sectional study. The samples were taken by consecutive method. We used Chi-square test and logistic regression analysis. Association between variables considered significant when p value < 0.05.

Result: There were 80 subjects with chronic phase CML. Mean of age was: 39,4 ± 13,1 years. Ratio male : female = 1 : 1. Ratio symptomatic : asymptomatic = 83,8% : 16,2%. The symptoms of chronic phase CML were: abdominal swelling, fatigue, abdominal bloating, night sweat, and abdominal lump. The vast majority of subjects with chronic phase CML revealed splenomegaly (83,8%). Hematological laboratory showed: mean of Hb level was 10,6 ± 1,7 g/dL, median of white blood cell count was 125.710 /uL, and median of platelet count was 470.000/uL. The proportion of Ph (+)/ BCR-ABL (+) CML was up to 90%. The comparison of clinical features and hematological laboratories between Ph (+)/ BCR-ABL (+) CML and other type of Ph/ BCR-ABL CML were: Simptomatic features 80,6% : 100%, Splenomegaly 82% : 92,3%, Median of Hb 10,3 g/dL : 10,3 g/dL, Median of white blood cell 124.620 : 127.050, Median of thrombocyte 455.000 : 487.000. Bivariate and multivariate analysis showed no significant variables both clinical features and hematological laboratories between Ph (+)/ BCR-ABL (+) CML and other type of Ph/ BCR-ABL CML.

Conclusion: There were no variables both clinical features and hematological laboratories have a significant relationship between Ph (+)/ BCR-ABL (+) CML and other type of Ph/ BCR-ABL CML."
