"ABSTRAK Latar belakang: Sarkoma Ewing merupakan suatu small round cell tumor yang ditandai dengan fusi gen EWSR1/FLI1 pada 85 kasus. Diagnosis akurat diperlukan karena memiliki respon baik terhadap protokol kemoterapi spesifik. Baku emas diagnosis sarkoma Ewing adalah deteksi translokasi spesifik dengan RT-PCR atau FISH, namun pemeriksaan tersebut belum tersedia di institusi kami, sehingga dilakukan upaya lain untuk mempertajam diagnosis. Secara morfologi, sarkoma Ewing sering overlapping dengan small round cell tumor lainnya. Pulasan CD99 merupakan penanda yang sangat sensitif untuk mendiagnosis sarkoma Ewing, namun juga sering overlapping dengan small round cell tumor lainnya. Beberapa penelitian mengemukakan FLI1 dapat digunakan sebagai penanda diagnosis sarkoma Ewing. Tujuan penelitian ini adalah menilai ekspresi FLI1 untuk membantu menegakkan diagnosis sarkoma Ewing pada small round cell tumor yang memberikan hasil positif terhadap CD99, terutama pada kasus biopsi.Bahan dan cara: Penelitian ini menggunakan desain potong lintang. Sampel terdiri atas 36 kasus sarkoma Ewing dan 18 kasus small round cell tumor yang sudah dilakukan pulasan imunohistokimia CD99 di RSCM dari Januari 2011 sampai Mei 2018. Dilakukan pulasan FLI1 dan penilaian menggunakan H-score.Hasil: Titik potong H-score pada ekspresi FLI1 didapatkan 226.1 75 dengan sensitivitas 81.6 dan spesifisitas 94.4 . Ekspresi FLI1 tinggi didapatkan pada 31 kasus sarkoma Ewing, sedangkan pada 18 kasus small round cell tumor umumnya memiliki ekspresi FLI1 yang rendah ABSTRACT Background: Ewing 39;s sarcoma is a small round cell tumor characterized by EWSR1 / FLI1 gene fusion in 85 of cases. Accurate diagnosis is necessary because it has a good response to a specific chemotherapy protocol. The gold standard of Ewing 39;s sarcoma diagnosis is the detection of specific translocation with RT-PCR or FISH, but the examination is not yet available at our institution, so another attempt is made to sharpen the diagnosis. Morphologically, Ewing 39;s sarcoma is often overlapping with other small round cell tumor. CD99 is a very sensitive marker for diagnosing Ewing 39;s sarcoma, but also often overlapping with other small round cell tumors. Several studies have suggested that FLI1 can be used as a marker of Ewing rsquo;s sarcoma. The purpose of this study was to assess the FLI1 expression to help establish the diagnosis of Ewing rsquo;s sarcoma in small round cell tumors that gave CD99 positive results, especially in the biopsy cases. Materials and methods: This was a cross-sectional study with 36 cases of Ewing rsquo;s sarcoma and 18 cases of other small round cell tumor that had been performed CD99 immunohistochemistry at RSCM from January 2011 to May 2018. All cases stained by FLI1 antibody and evaluated using H-score. Results: The H-score cut-off point on FLI1 expression was obtained at 226.1 75 with 81.6 sensitivity and 94.4 specificity. The high FLI1 expression was obtained in 31 cases of Ewing rsquo;s sarcoma, while in 18 cases of small round cell tumor were generally had low expression of FLI1 p"

"ABSTRACTSel tumor adalah sel yang terbentuk akibat kegagalan beberapa protein dalam mengatur siklus sel. Protein TP53 berperan penting dalam mengatur siklus sel, khususnya dalam menekan perkembangan sel tumor. Perubahan pada gen TP53 ditemukan dalam lebih dari setengah kasus tumor pada manusia. Protein lain yang berhubungan dengan protein TP53 juga ditemukan terlibat dalam proses pembentukan kanker. Analisis interaksi protein TP53 dengan melakukan clustering jaringan interaksi protein (PPI) TP53 adalah hal penting dalam membantu mengatasi sel tumor. Jaringan PPI dinyatakan sebagai graf dengan protein dan interaksinya masing-masing sebagai simpul dan busur pada graf. Spectral clustering adalah metode graph clustering yang menggunakan eigenvector dari matriks Laplacian.

ABSTRACTFuzzy random walk adalah metode fuzzy clustering yang menggunakan probabilitas transisi dari random walk pada data. Dua metode tersebut akan digabungkan dan diimplementasikan pada penelitian ini. Menggunakan data PPI protein TP53 dari STRING database, didapat gabungan kedua metode tersebut mampu menghasilkan cluster yang fuzzy dan robust di mana setiap cluster dapat menjelaskan bagian tertentu dari fungsi protein TP53. Tumor cell is formed as a result of malfunctioning of some proteins that regulates the cell cycle. TP53 protein plays an important role in managing cell cycle, especially in tumor cell suppression. An alteration of TP53 gene is found in more than half cases of human tumor. Moreover, TP53-related proteins are also found involved in the carcinogenesis process. Therefore, it is important to analyze the interactions of TP53 protein by clustering protein-protein interactions (PPI) network of TP53. PPI networks are usually represented as a graph network with proteins and interactions as vertices and edges respectively. Spectral Clustering is a graph clustering algorithm based on eigenvector of the graph Laplacian. Fuzzy Random Walk is a fuzzy clustering method based on transition probability from a random walk on a dataset. In this paper, we combine both Spectral Clustering and Fuzzy Random Walk. Using PPI datasets of TP53 obtained from the STRING database, we found the combined algorithm is proven to produce both robust and fuzzy clusters with each cluster explains one of TP53 proteins functionality."

"Pembentukan dan perkembangbiakan sel tumor terjadi jika protein khusus yang mengatur pembelahan sel mengalami perubahan fungsi, ekspresi gen atau hilang keduanya. Salah satu protein penekan tumor yang berperan dalam pengendalian siklus sel adalah protein TP53. Pada sebagian besar perubahan genetik dalam tumor, baik delesi atau mutasi pada lebih dari 50% kanker pada manusia, ditemukan mutan TP53 yang merupakan faktor beresiko tinggi terhadap kanker. Oleh karena itu, penting untuk melakukan studi tentang pengelompokan interaksi protein-protein TP53. Interaksi protein secara umum disajikan dalam jaringan graf (graph network) dengan protein sebagai simpul dan interaksinya sebagai busur. Algoritma Markov Clustering (MCL) adalah satu metode graph clustering yang dibuat berdasarkan simulasi dari flow stokastik pada suatu graf. Dalam skripsi ini, dibahas mengenai implementasi algoritma MCL pada data interaksi protein-protein TP53 dengan menggunakan bahasa pemrograman Python. Algoritma MCL terdiri dari tiga operasi utama yaitu ekspansi, penggelembungan, dan pemotongan. Selanjutnya, dilakukan analisis hasil clustering dari simulasi algoritma MCL dengan menggunakan parameter ekspansi, penggelembungan dan faktor pengali yang berbeda-beda. Berdasarkan analisis hasil clustering yang dilakukan, algoritma MCL terbukti menghasilkan robust cluster dengan protein TP53 sebagai pusat cluster untuk setiap hasil clustering.

The formation and proliferation of tumor cells occurs if a special protein that regulates cell division changing the function, gene expression or lost both. One of the tumor suppressor protein that plays a role in controlling the cell cycle is the TP53 protein. In most of the genetic changes in the tumor, either deletions or mutations in more than 50% of human cancers, it found that mutant of TP53 is a high risk factor for cancer. Therefore, it is important to conduct studies on protein-protein interactions clustering of TP53. Protein interactions are generally presented in the graph network with proteins as nodes and interactions as edges. Markov Clustering (MCL) algorithm is a graph clustering method which is based on a simulation of stochastic flow on a graph. This minithesis discussed about the implementation of the MCL process on protein-protein interaction of TP53 data using the Python programming language. MCL algorithm consists of three main operations: expansion, inflation, and prune. Furthermore, the clustering simulation is using the different parameter of expansion, inflation and the multiplier factor. Based on the analysis of the clustering results, MCL algorithm is proven to produce robust cluster with TP53 protein as a centroid for each clustering results."

Twenty percent of bone tumor surgery requires intraoperative blood tranfusion, mostly Packed Red Cell (PRC). Approximately 1200ml or 4-6 unit of PRC transfusion is given in a bone tumor surgery.^1,2Less accurate estimation of the need of transfusion caused excessively wasted blood requests and led to high expense loss. In January-July 2017 there were 7972 wasted bags of blood product, resulting in a loss of Rp. 5,381,100,000 in Cipto Mangunkusumo Hospital. This study aimed to develop a prediction model for the need of perioperative red blood cell transfusion in bone tumor surgery. This is a retrospective cohort study of adults patients underwent bone tumor surgery between 2015 to 2017. Data was retrieved from the medical records and 82 subjects were included. The bivariate analysis showed that tumor location, size, malignancy, preoperative hemoglobin level and ASA physical status were significantly correlated with perioperative needs of red blood cell transfusion. However, the linear regression showed that only tumor location and preoperative hemoglobin level were considered as significant predictors. Therefore we obtained an alternative model from logistic regression to determine the probability of the need for perioperative PRC transfusion and add additional factors in the analysis."

Background: As part of liquid biopsy, CTCs play a role in monitoring breast cancer patients undergoing therapy. The existence of CTCs is a sign of therapy resistance and affects patient prognosis. This study aims to examine whether there are changes in CTC values in patients with locally advanced or advanced breast cancer, who receive chemotherapy and are influenced by age, menopause status, subtype, metastasis, and grade.

Method: Of the 30 samples of locally advanced or advanced breast cancer patients receiving Anthracycline and Taxan-based chemotherapy were obtained. Pre-chemotherapy, peripheral blood, was drawn and CTCs were examined using flow cytometry with EpCAM antibody. Patients then undergo a complete chemotherapy cycle. After that, the patients were again taken peripheral blood and examined for post-chemotherapy CTC values.

Result: The study was conducted at Cipto Mangunkusumo Hospital, started from December 2022 to December 2023. Of the 30 samples with the mean age was 47,93+7,30. A total of 56,7 (n=17) were not menopause, 43,3% of tumor status with the T3 and T4, and the most common lymph node status with the N0 and N1 (43,3%). Only two patients were found to have metastasis. Then, 56,7% of patients had grade 3, and the most common subtype was luminal B (63,4%, n=19). There were 22 patients (73,3%) with ER positive, 14 patients (46,7%) with PR positive, 11 patients (36,7%) with Her2 positive, and 21 patients (70%) with Ki67 high proliferation. Pre-chemotherapy CTC results obtained a median value of 1460.50, Meanwhile, post-chemotherapy CTC obtained a median value of 415,50. Wilcoxon test was performed and the difference was significant with a value of p = 0,002. Multivariate linear regression analysis was correlated between the decrease in CTC values with age, menopause status, subtype, metastasis, and grading. The menopausal status has a significant association with decrease CTC values (p<0,05).

Conclusion: CTC in locally advanced and advanced breast cancer patients after chemotherapy was significantly lower than before chemotherapy. menopause status has a significant association with decreased CTC values after chemotherapy in locally advanced and advanced breast cancer."

"Kanker kolorektal menempati urutan kedua dengan jumlah kasus tertinggi di dunia. Kanker kolorektal dapat dideteksi dengan menggunakan kolonoskopi, namun metode tersebut bersifat invasif. Oleh karena itu, penggunaan liquid biopsy dapat digunakan sebagai metode alternatif karena tergolong semi-invasif. Metode liquid biopsy yang digunakan adalah menggunakan darah dari pembuluh perifer. Di dalam darah terdapat beragam komponen penyusun, salah satunya adalah Circulating Tumor Cells (CTC). Circulating Tumor Cells dapat dikarakterisasi dengan menggunakan penanda spesifik sitokeratin 20 (CK20) karena pendaran ekspresinya yang tinggi pada kanker kolorektal. Proses isolasi CTC dari sampel darah dapat dilakukan dengan bervariasi metode, salah satunya dengan red blood cells lysis (eritrolisis). Penelitian ini bertujuan untuk mengisolasi CTC dengan penanda CK20 dari sampel darah perifer serta mengetahui karakteristik dan jumlah CTC yang diperoleh dari subjek kanker kolorektal di RSUPN Dr. Cipto Mangunkusumo. Pada penelitian ini sampel darah diambil dari lima subjek kanker kolorektal. Untuk mengoptimalisasi hasil isolat CTC yang nantinya diperoleh maka dilakukan spike-in experiment dengan penambahan sel HT-29 ke dalam donor sehat. Hasil penelitian ini menunjukkan bahwa CTC ditemukan di seluruh subjek dengan rata-rata perolehan 6 CTC tunggal dan 1 CTC cluster dari 2 mL darah. Dengan demikian, immunofluorescence dapat digunakan untuk mengarakterisasi tipe morfologinya, yaitu CTC tunggal dan CTC cluster.

Colorectal cancer ranks second with the highest number of cases in the world. Colorectal cancer can be detected using colonoscopy, but this method is invasive. Therefore, liquid biopsy can be used as an alternative method because it is classified as semi-invasive. The liquid biopsy method used is using blood from peripheral vessels. In the blood there are various constituent components, one of which is Circulating Tumor Cells (CTCs). Circulating Tumor Cells can be characterized using the specific marker cytokeratin 20 (CK20) due to its high expression in colorectal cancer. The process of isolating CTCs from blood samples can be carried out using various methods, one of which is red blood cells lysis (erythrolysis). This study aims to isolate CTCs with the CK20 marker from peripheral blood samples and determine the characteristics and number of CTCs obtained from colorectal cancer subjects at RSUPN Dr. Cipto Mangunkusumo. In this study, blood samples were taken from five colorectal cancer subjects. To optimize the CTCs isolate results that will be obtained, a spike-in experiment was carried out by adding HT-29 cells to healthy donors. The results of this study showed that CTCs were found in all subjects with an average of 6 single CTCs and 1 cluster CTCs from 2 mL of blood. Thus, immunofluorescence can be used to characterize the morphological types, namely single CTCs and cluster CTCs."

"Kanker kolorektal merupakan jenis kanker dengan jumlah penderita terbanyak ketiga di dunia. Metode deteksi kanker kolorektal yang banyak digunakan yakni kolonoskopi, namun metode tersebut bersifat invasif dan mahal. Salah satu metode deteksi yang dapat digunakan sebagai alternatif adalah melalui deteksi penanda molekuler adalah CK20 pada Circulating Tumor Cells (CTC) yang terdapat dalam darah perifer. Permasalahan muncul akibat rendahnya jumlah CTC dalam darah. Deteksi gen CK20 pada serum darah berpotensi menjadi metode deteksi kanker kolorektal karena serum darah mengandung cell-free nucleic acid (cfNA) yang dilepaskan oleh sel tumor. Tujuan dari penelitian ini adalah untuk mendeteksi gen CK20 pada CTC dan serum darah dari penderita kanker kolorektal. Isolat RNA diisolasi dari sampel CTC dan serum darah yang berasal dari empat penderita kanker kolorektal RSUPN Cipto Mangunkusumo kemudian diamplifikasi melalui Quantitave RT-PCR dan dianalisis melalui metode Melt Curve Analysis (MCA). Hasil menunjukkan bahwa gen CK20 memiliki Tm ~81°C dan terdeteksi pada satu sampel serum dan dua sampel jaringan. Berdasarkan hasil yang diperoleh, dapat disimpulkan bahwa gen CK20 tidak terdeteksi pada CTC dan terdeteksi pada satu serum darah penderita kanker kolorektal.

Colorectal cancer occupies the third-highest number of cancer patients worldwide. The most widely used colorectal cancer detection method is colonoscopy. However, colonoscopy is invasive and expensive. One alternative detection method is the detection of molecular markers such as CK20 in circulating tumor cells (CTC) found in the peripheral blood. The problem arises due to the low number of CTCs in the blood. Detection of the CK20 gene in blood serum is potentially used as a colorectal cancer detection method because blood serum contains cell-free nucleic acid (cfNA) released by tumor cells. This study aimed to detect the CK20 gene in CTCs and blood serum from colorectal cancer patients. RNA isolates were isolated from CTC samples and blood serum from four colorectal cancer patients at Cipto Mangunkusumo Hospital and then amplified by quantitative RT-PCR and then analyzed using the Melt Curve Analysis method. The results showed that the CK20 gene had a melting temperature of an average of ~81°C and was detected in one blood serum sample and two cancer tissue samples. Based on the results obtained, it can be concluded that the CK20 gene was undetected in CTCs and detected in one blood serum of colorectal cancer patients."
