"Latar Belakang: Diffuse Large B-cell Lymphoma (DLBCL) merupakan limfoma tersering di Indonesia. Kemoterapi R-CHOP mempunyai risiko moderat untuk terjadinya neutropenia / demam neutropenia. Limfosit dapat menggambarkan imunitas pejamu, sedangkan neutrofil dan monosit dapat menggambarkan respons inflamasi. Belum ada penelitian yang menilai hitung jenis leukosit sebagai prediktor neutropenia akut awitan pertama pascakemoterapi R-CHOP pada pasien DLBCL.Tujuan: Mengetahui hubungan parameter hitung jenis leukosit sebelum kemoterapi sebagai prediktor neutropenia akut awitan pertama pascakemoterapi R-CHOP pada pasien DLBCL.Metode: Kohort retrospektif di RSUPN. Cipto Mangunkusumo. Pasien DLBCL 18-60 tahun, ECOG 0-1, tanpa komorbid yang berhubungan dengan kemoterapi, yang dilakukan kemoterapi R-CHOP 3 siklus pertama tanpa profilaksis G-CSF.Hasil: Dari 95 pasien, neutropenia akut awitan pertama pascakemoterapi terjadi pada 83 (87,4%) subjek atau 83 (55,3%) siklus dari total 150 siklus kemoterapi. Demam neutropenia terjadi pada 50,6% dari awitan neutropenia. Neutropenia berat terjadi pada 34 (41,0%) siklus dari 83 episode neutropenia. Neutropenia akut awitan pertama paling sering terjadi pada 7-15 hari pascakemoterapi.Rasio neutrofil limfosit mempunyai AUROC 0,74 (IK 95% 0,6-0,82); sedangkan limfosit absolut, neutrofil absolut, monosit absolut, dan rasio limfosit monosit mempunyai AUROC <0,70. Rasio neutrofil limfosit > 4,1 dapat memprediksi neutropenia akut awitan pertama pascakemoterapi RCHOP pada pasien DLBCL (sensitivitas 71,1%; spesivisitas 64,2%; nilai duga positif 71,1%; dan nilai duga negatif 64,2%).

Background: Diffuse Large B-cell Lymphoma (DLBCL) is the most common lymphoma in Indonesia. R-CHOP chemotherapy has a moderate risk for neutropenia / febrile neutropenia. Lymphocytes can describe host immunity, while neutrophils and monocytes can describe the inflammatory response. No study has assessed differential count of leukocytes as a predictor of the first onset acute neutropenia after R-CHOP chemotherapy in DLBCL patients.

Objective: To determine the relationship between differential count of leukocytes before chemotherapy as a predictor of the first onset acute neutropenia after R-CHOP chemotherapy in DLBCL patients.

Methods: Retrospective cohort in RSUPN. Cipto Mangunkusumo. DLBCL patients 18-60 years old, ECOG 0-1, no comorbidity related to chemotherapy. Subjects were given with the first 3 cycles of R-CHOP chemotherapy without G-CSF prophylaxis.

Results: Of the 95 patients, first onset acute neutropenia after chemotherapy occurred in 83 (87.4%) subjects or 83 (55.3%) cycles of 150 chemotherapy cycles. Febrile neutropenia occurs in 50,6% of the onset of neutropenia. Severe neutropenia occurs in 34 (41.0%) cycles of 83 neutropenic episodes. The first onset of acute neutropenia is most common at 7-15 days after chemotherapy.

The neutrophil lymphocyte ratio has AUROC 0.74 (95% CI 0.65-0.82); while absolute lymphocytes, absolute neutrophils, absolute monocytes, and monocyte lymphocyte ratios have AUROC <0.70. The neutrophil lymphocyte ratio > 4.1 can predict the first onset of acute neutropenia after RCHOP chemotherapy in DLBCL patients (sensitivity 71.1%; specificity 64.2%; positive predictive value 71.1%; negative predictive value 64.2%).

Conclusion: The neutrophil lymphocyte ratio before chemotherapy > 4.1 has moderate performance in predicting the first onset of acute neutropenia post R-CHOP chemotherapy in DLBCL patients. Absolute lymphocytes count, monocytes count, neutrophils count, and monocyte lymphocyte ratio cannot be used as a predictor of the first onset acute neutropenia post R-CHOP chemotherapy in DLBCL patients."

"Latar belakang: Respon terapi diffuse large B-cell lymphoma (DLBCL) sangat heterogen. Skor IPI dan subtype DLBCL berdasarkan algoritma Hans masih banyak dipakai untuk menentukan prognosis. Jumlah monosit absolut (AMC) dan Tumor microenviroment (TME)  memiliki peranan penting dalam memprediksi  terjadinya event pada DLBCL. Beberapa TME yang telah dikaji adalah tumor associated macrophage (TAM), dan tumor infiltrating lymphocytes (TIL), namun masih terdapat hasil yang kontradiktif terhadap tingkat survival pasien DLBCL yang mendapatkan regimen terapi RCHOP dalam dua tahun.Tujuan penelitian: Mengetahui hubungan antara AMC,  TAM dan TIL terhadap event free survival 2 Tahun  pada  DLBCL yang mendapatkan terapi RCHOP.Metode penelitian: Penelitian ini adalah studi kohort retrospektif dengan mengambil data rekam medis pasien dari Rumah Sakit dr. Cipto Mangunkusumo (RSCM) yang terdaftar sejak Januari 2014-Maret 2021. Kami mengumpulkan data demografis, hasil pemeriksaan klinis,  laboratorium, termasuk AMC, pemeriksaan radiologi dan event selama 2 tahun. Pemeriksaan CD163 dan CD8 menggunakan pewarnaan imunohistokimia antibodi dari parafin blok biopsi jaringan. Kami menganalisis nilai cut off terbaik dari AMC, CD163, dan CD8 dalam menentukan survival dua tahun dan korelasi AMC terhadap CD163 dan CD8.Hasil: Kami menganalisis sebanyak 108 pasien (52% laki-laki, 33,3% usia lebih dari enam puluh tahun). Ditemukan nilai cut off terbaik AMC, CD163, dan CD8 berturut-turut adalah 631, 23, dan 27,5%. Terdapat hubungan yang bermakna berturut-turut antara AMC dan CD163 serta CD8 (r=0,577, p<0,001; r=-0,599, p<0,001). Kesimpulan dari penelitian ini ditemukan AMC, TAM M2 (CD163) dan TIL CD8 secara kuantitatif berhubungan dengan event free survival 2 tahun pada pasien DLBCL yang mendapatkan terapi RCHOP. Terdapat hubungan korelasi positif sedang antara AMC dengan TAM M2 (CD163),  dan hubungan korelasi negatif sedang antara AMC dengan  TIL CD8.

Background: Response to therapy of diffuse large B-cell lymphoma (DLBCL) is very heterogeneous. IPI scores and DLBCL subtypes based on Hans' algorithm are still widely used to determine prognosis. Absolute monocyte count (AMC) and tumor microenvironment (TME) are important in predicting events in DLBCL. Several TMEs studied are tumor-associated macrophages (TAM) and tumor-infiltrating lymphocytes (TIL). However, there are still contradictory results regarding the survival rate of DLBCL patients who receive RCHOP therapy regimens within two years.

Objective: This study aimed to determine the correlation between AMC, TAM, and TIL on 2-year event-free survival in DLBCL receiving RCHOP therapy.

Methods: This research is a retrospective cohort study by taking patient medical record data from Dr. Cipto Mangunkusumo Hospital (RSCM) registered from January 2014-March 2021. We collected demographic data, clinical and laboratory examinations, including AMC, radiological examinations, and events for 2 years. Examine CD163 and CD8 using antibody immunohistochemical staining of paraffin tissue biopsy blocks. We analyzed the best cut-off values ​​of AMC, CD163, and CD8 in determining two-year survival and the correlation of AMC to CD163 and CD8.

Results: We analyzed 108 patients (52% male, 33.3% over sixty). It was found that the best cut-off values ​​for AMC, CD163, and CD8 were 631, 23, and 27.5%, respectively. There was a significant relationship between AMC and CD163 and CD8, respectively (r=0.577, p<0.001; r=-0.599, p<0.001). This study concluded that AMC, TAM M2 (CD163), and TIL CD8 were quantitatively associated with 2-year event-free survival in DLBCL patients receiving RCHOP therapy. A moderate positive correlation exists between AMC and TAM M2 (CD163) and a moderate negative correlation between AMC and TIL CD8."

"Background: Diffuse large B-cell lymphoma (DLBCL) merupakan keganasan limfoid yang paling sering terjadi di dunia. DLBCL memiliki 2 subtipe yaitu germinal center B- cell-like (GCB) dan non-GCB. Programmed cell death-1 (PD-1) merupakan protein transmembran tipe 1 dari anggota imunoglobulin B7/CD28 sebagai reseptor imunomodulator yang memiliki peranan penting mencegah terjadinya kelainan autoimun. PD-1 di ekspresikan pada sel T, sel B dan sel natural killer. PD-1 memiliki ligan yaitu programmed cell death ligand-1 (PD-L1). PD-L1 banyak diekspresikan di beberapa jenis sel tumor dan di lingkungan mikro tumor. Salah satu karakteristik dari sel kanker adalah mampu menghindari destruksi dari sistem imun dengan cara mengaktivasi jalur PD-1/PD-L1. Peningkatan ekspresi PD-L1 memiliki asosiasi dengan prognosis yang buruk sedangkan peningkatan ekspresi PD-1 memiliki asosiasi dengan prognosis yang baik. Ekspresi PD-1 dan PD-L1 sudah diteliti pada kanker paru, namun jarang diteliti pada pasien DLBCL. Pada penelitian ini akan dievaluasi perbedaan antara ekspresi PD-1 dan PD-L1 pada pasien DLBCL subtipe GCB dan non-GCB. Metode: 20 kasus DLBCL subtipe GCB dan 20 kasus DLBCL subtipe non-GCB dalam sedian blok parafin (formalin-fixed paraffin-embedded tissue) dari Departemen Patologi Anatomik RSCM-FKUI pada periode tahun 2014 hingga 2017. Ekspresi PD-L1 dan PD-1 dievaluasi dengan teknik imunohistokimia. Ekspresi PD-L1 dievaluasi pada sel tumor, sedangkan ekspresi PD-1 dievaluasi di limfosit. Hasil: Terdapat perbedaan bermakna ekspresi PD-L1 pada sel tumor pasien DLBCL subtipe GCB dan non-GCB (P < 0,05), sedangkan ekspresi PD-1 tidak di diekspresikan pada limfosit pasien DLBCL subtipe GCB dan non-GCB. Kesimpulan: Terdapat peningkatan bermakna ekspresi protein PD-L1 yang diekspresikan pada sel tumor pasien DLBCL subtipe non-GCB dibandingkan subtipe GCB. Tidak terdapat ekspresi PD-1 pada limfosit pasien DLBCL subtipe GCB dan non-GCB.

Background: Diffuse large B-cell lymphoma (DLBCL) is one of the most common lymphoid malignancies in the world and has two major molecular subtypes, germinal center B-cell-like (GCB) and non-GCB. Program cell death-1 (PD-1) is a type 1 transmembrane protein from members of immunoglobulin B7/CD28 as immunomodulator receptor that has an important role in preventing autoimmune disorder. PD-1 is expressed in T cells, B cells and natural killer cells. Program cell death ligand-1(PD-L1) is ligand of PD-1. PD-L1 is expressed in several types of tumor cells and in tumor microenvironment. One of cancer cells characteristic is the ability to avoid destruction of the immune system by activating PD-1 /PD-L1 pathway. Increased of PD-L1 expression is associated with poor prognosis while increased of PD-1 expression is associated with good prognosis. Expressions of PD-1 and PD-L1 have been studied in lung cancer, but study in DLBCL patients is limited. In this research, we evaluated the difference between PD-1 and PD-L1 expression in GCB and non-GCB subtypes of DLBCL. Methods: 20 cases of GCB subtype of DLBCL and 20 cases of non-GCB subtype of DLBCL in formalin-fixed paraffin-embedded tissue (FFPE) were taken from the archive of the Anatomical Pathology Department of RSCM-FKUI during 2014 to 2017. The expression of PD-L1 and PD-1 were evaluated by immunohistochemical technique. Expression of PD-L1 was evaluated in tumor cells, whereas PD-1 expression was evaluated in lymphocyte. Result: There was significant differences between PD-L1 expression in tumor cells of GCB subtype of DLBCL as compared to non-GCB subtype (P <0.05). The expression of PD-1 was not found in lymphocytes of GCB and non-GCB subtypes of DLBCL. Conclusion: The expression of PD-L1 in tumor cells of non-GCB subtype of DLBCL increased significantly as compared to GCB subtype. The expression of PD-1 protein was not found in lymphocyte cell of GCB as well as non-GCB subtypes of DLBCL."

"Diffuse large B-cell lymphoma (DLBCL) merupakan limfoma jenis sel B tersering pada kasus limfoma non-Hodgkin dan bersifat agresif, sehingga dibutuhkan diagnosis dan terapi yang cepat dan tepat. Terdapat beberapa kriteria prognosis untuk pasien DLBCL salah satunya klasifikasi Hans. Berdasarkan klasifikasi Hans, DLBCL dibagi menjadi subtipe Germinal Center B-cell-like (GCB) dan Non-Germinal Center B-cell-like (non-GCB). Beberapa pasien tidak menunjukkan respons yang baik terhadap terapi kombinasi dengan rituximab (R-CHOP). Para peneliti sedang mencari pengobatan terbaru DLBCL yang sulit diobati atau sering kambuh. Salah satunya menggunakan imunoterapi anti-CTLA-4. Penelitian ini bertujuan untuk menilai ekspresi CTLA-4 pada DLBCL subtipe GCB dan non-GCB. Penelitian retrospektif analitik ini menggunakan 50 sampel blok parafin yang sebelumnya telah didiagnosis sebagai DLBCL subtipe GCB dan non-GCB yang tercatat di arsip Departeman Patologi Anatomik FKUI/RSCM. Rerata ekspresi CTLA-4 pada DLBCL ditemukan lebih banyak pada subtipe non-GCB (61,66 sel/lapang pandang besar) dibandingkan subtipe GCB (40,5 sel/lapang pandang besar) (p=0,076). Rerata ekspresi CTLA-4 lebih tinggi pada kelompok usia £ 60 tahun, perempuan, stadium penyakit III-IV, dan keterlibatan >1 lokasi ekstranodal. Rerata ekspresi CTLA-4 lebih tinggi pada kelompok skor IPI rendah (0-2) dibandingkan skor IPI tinggi (3-5). Tidak ditemukan perbedaan ekspresi CTLA-4 yang bermakna pada DLBCL subtipe GCB dan non-GCB, meskipun terdapat tren rerata ekspresi CTLA-4 yang lebih tinggi pada kelompok non-GCB.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of B-cell non-Hodgkin's lymphoma and is aggressive in nature, so prompt and appropriate diagnosis and treatment are needed. There are several prognostic criteria for DLBCL patients, one of which is the Hans classification. Based on Hans classification, DLBCL is divided into Germinal Center B-cell-like (GCB) and Non-Germinal Center B-cell-like (non-GCB) subtypes. Some patients do not respond well to combination therapy with rituximab (R-CHOP). Researchers are looking for new treatments for DLBCL that is difficult to treat or recurs frequently. One of them uses anti-CTLA-4 immunotherapy. This study aimed to assess the expression of CTLA-4 in GCB and non-GCB DLBCL subtypes. This analytic retrospective study used 50 samples of paraffin blocks previously diagnosed as GCB and non-GCB subtype DLBCL recorded in the archives of the Department of Anatomic Pathology FKUI/RSCM. The average CTLA-4 expression in DLBCL was found to be higher in the non-GCB subtype (61.66 cells/high power field) than the GCB subtype (40.5 cells/high power field) (p=0.076). The average CTLA-4 expression was higher in the age group 60 years, women, stage III-IV disease, and involvement of >1 extranodal site. The average CTLA-4 expression was higher in the low IPI score group (0-2) than in the high IPI score group (3-5). There was no significant difference in CTLA-4 expression in GCB and non-GCB DLBCL subtypes, although there was a trend of higher mean CTLA-4 expression in the non-GCB group.

"Latar Belakang: Respon DLBCL terhadap terapi sangatlah heterogen. Algoritme Hans (ekspresi protein CD10, BCl6, MUM1 dengan cut off 30%) tidak selalu konsisten dalam memprediksi prognosis. Peran Ki 67 sebagai petanda proliferasi sel tumor sebagai faktor prognostik pada DLBCL juga masih belum diketahui secara jelas. Tujuan: Mengetahui hubungan ekspresi protein CD10, BCL6, MUM1, dan Ki67 secara kuantitatif dalam memprediksi event- free survival 24 bulan pasien DLBCL yang mendapatkan terapi R-CHOP. Metode: Dilakukan analisis hubungan antara antara ekspresi protein CD10, BCL6, MUM1, dan Ki67 secara kuantitatif dengan event- free survival 24 bulan pada pasien DLBCL yang mendapatkan terapi R-CHOP di RSCM pada tahun 2014-2017. Analisis sekunder juga dilakukan terhadap skor IPI dan peningkatan kadar LDH. Penelitian ini merupakan studi kohort retrospektif, menggunakan analisis kesintasan dan regresi logistik. Hasil: Terdapat perbedaan kurva kesintasan yang bermakna pada ekspresi protein MUM1 dengan cut off optimal 70% pada 92 pasien. Juga didapatkan perbedaan kurva kesintasan yang bermakna pada pasien dengan kadar LDH lebih dari 3 kali nilai normal. Kombinasi peningkatan ekspresi protein MUM1 secara kuantitatif dan peningkatan kadar LDH lebih dari 3 kali nilai normal dapat memprediksi terjadinya event dalam 24 bulan pasien pada DLBCL yang mendapatkan terapi R-CHOP. Simpulan: Ekspresi protein MUM1 lebih dari atau sama dengan 70% dan kadar LDH serum lebih dari 3 kali nilai normal dapat membantu memprediksi event- free survival 24 bulan.

Background: Treatment response in DLBCL is heterogenous. Hans algorithm (CD10, BCL6, MUM1 protein expression, cut off 30%) is not always consistent in predicting prognosis. The significance of Ki67 protein expression as prognostic factor in DLBCL is still controversial. Objective: To analyze the correlation of quantitative protein expression CD10, BCL6, MUM1, and Ki67 in predicting event-free survival at 24 months in DLBCL patients receiving R-CHOP therapy. Methods: DLBCL patients receiving R-CHOP therapy in Cipto Mangunkusumo Hospital from 2014-2017 were analyzed for the correlation between quantitative protein expression CD10, BCL6, MUM1, and KI67 with event-free survival at 24 months. We also do the secondary analysis to the IPI score and the level of the lactate dehydrogenase serum. This is a retrospective study, using survival analysis and logistic regression. Results: There is significant survival difference between MUM1 expression cut-off more or equal to 70% in 92 DLBCL patients receiving R-CHOP therapy. There is also significant difference between LDH more than 3 times normal regarding survival curve. Combination of MUM1 expression and LDH serum can help predict event within 24 months. Conclusions: Quantitative protein expression MUM1 of more or equal to 70% and serum LDH more than 3 times normal can predict event-free survival at 24 months."

"Latar belakang: Primary mediastinal large B cell lymphoma (PMBCL) adalah limfoma sel B berasal dari sel B medulla timus yang memiliki sifat unik dan agresif. Jaringan tumor PMBCL paling sering didapat berupa jaringan core biopsy. Gambaran histopatologik PMBCL berupa spektrum dengan fenotip dan genetik mirip dengan limfoma Hodgkin klasik terutama subtipe nodular sklerosis. Hal-hal tersebut dapat menimbulkan kesulitan diagnosis sehingga diperlukan pemeriksaan imunohistokimia untuk penegakan diagnosis dan penentuan pengobatan. Beberapa penelitian menemukan MAL merupakan salah satu penanda PMBCL. Tujuan penelitian ini adalah mengetahui perbedaan ekspresi MAL pada PMBCL dan limfoma Hodgkin klasik mediastinum.Bahan dan cara: Penelitian ini menggunakan desain potong lintang. Sampel terdiri atas 15 kasus PMBCL dan 15 kasus limfoma Hodgkin klasik mediastinum yang sudah dilakukan pulasan imunohistokimia dari Januari 2011 sampai Mei 2018. Dilakukan pulasan MAL dan penilaian menggunakan perhitungan persentase >10% sel tumor. Hasil: Ekspresi MAL positif pada  2(13,3%) dari 15 kasus PMBCL dan limfoma Hodgkin klasik mediastinum sebanyak 8(53,3%) kasus dari 15 kasus dengan sensitivitas 20% dan spesifisitas 35%. Pada uji statistik chi-square didapatkan ekspresi MAL antara PMBCL dan limfoma Hodgkin klasik berbeda bermakna dengan nilai  p=0,020.Kesimpulan: Ditemukan ekspresi MAL antara PMBCL dengan limfoma Hodgkin klasik mediastinum berbeda bermakna.

Background: Primary mediastinal large B-cell lymphoma (PMBCL) is an aggressive and unique large B-cell lymphoma arising in mediastinum of putative thymic B-cell origin. Core biopsy is most commonly diagnostic procedure in PMBCL mass. Morphology of PMBCL has spectrum and similarities in phenotype and genetic with classical Hodgkin lymphoma especially nodular sclerosis variant. Hence specific immunohistochemistry is needed to diagnose PMBCL. Several studies found MAL is one of some markers for PMBCL. The aim of this study is to determine the differences of MAL expression in PMBCL and thymic classical Hodgkin lymphoma.Material and method: This was a cross-sectional study with 15 cases of PMBCL and 15 cases thymic classical Hodgkin lymphoma that had been performed immunohistochemistry at RSCM from January 2011 to May 2018. All cases stained by MAL antibody and evaluated using percentage > 10% cell tumors.Result: MAL positive expression can be found in  2 (13,3%) of 15 cases PMBCL and  8 (53,3%) of 15 cases classical Hodgkin lymphoma with 20% sensitivity dan 35% specificity. The chi-square test showed  significant difference between MAL expression in PMBCL and thymic classical Hodgkin lymphoma. (p=0,020). Conclusion: There was signification difference between MAL expression in PMBCL and thymic classical Hodgkin lymphoma."

"ABSTRAKLatar belakang: Kemoterapi pilihan untuk Diffuse Large B Cell Lymphoma (DLBCL) adalah regimen yang mengandung doksorubisin. Doksorubisin merupakan obat kemoterapi golongan antrasiklin yang bekerja sebagai anti Topoisomerase II (Top2). Penelitian sebelumnya terhadap galur sel tumor menunjukkan bahwa ekspresi Topoisomerase IIα (Top2A) yang tinggi berhubungan dengan sensitifitas terhadap antrasiklin yang tinggi pula. Tujuan penelitian ini adalah untuk mengetahui ekspresi protein Top2A pada DLBCL dan hubungannya dengan respon terapi.Bahan dan cara kerja: Dilakukan studi analitik potong lintang terhadap 38 kasus DLBCL dengan pulasan CD20 positif dan telah mendapatkan kemoterapi minimal 4 siklus. Dilakukan pulasan imunohistokimia terhadap protein Top2A dan dinilai menggunakan H-score.Hasil: Secara keseluruhan ekspresi Top2A ditemukan pada 37 dari 38 kasus (97,4%) dengan nilai H-score sangat bervariasi yaitu antara 101,5 sampai dengan 215,0 dan median 124,1. H-score Top2A digolongkan tinggi jika H-score lebih dari 124,1. Analisis statistik menunjukkan bahwa ekspresi Top2A pada DLBCL tidak berhubungan bermakna dengan respon terapi (p=0,670).Kesimpulan: Tidak ditemukan hubungan bermakna antara ekspresi Top2A dengan respon terapi. Ekspresi Top2A tidak dapat dijadikan faktor prediktor respon terapi pada DLBCL.

ABSTRACTBackground: Standard of chemotherapy for Diffuse Large B Cell Lymphoma (DLBCL) is a regimen containing doxorubicin. Doxorubicin is a component of anthracycline based chemotherapy that work as anti Topoisomerase II (Top2). Previous study on tumor cell lines showed that high expression of Topoisomerase IIα (Top2A) was related to higher sensitivity to anthracycline. The aim of this study is to know the expression of Top2A and its relation to treatment response. Material and methods: This is an analytic cross-sectional study on 38 CD20 positive DLBCL cases that have been treated with at least 4 cycles of chemotherapy. The immunohistochemical staining for Top2A protein was performed assesed using H-score.Result: Expression of Top2A protein were found in 37 of 38 (97,4%) cases (H-score range: 101.5-215.0 and median 124.1). Top2A was defined as high if H-score was higher than 124.1. Statistical analysis showed that Top2A expression in DLBCL was not significantly related to treatment response (p=0.670).Conclusion : There was no significant relation between Top2A expression to treatment response. Top2A expression in DLBCL cannot be used as a predictor of treatment response."

Background : Cytostatic chemotherapy is reported to increasecoagulation activity (increased D-dimer) and change the hypercoagulable stateinto hypercoagulation. Hypercoagulable state is a condition that has the potentialfor thrombosis (for example in cancer patients) characterized by changes in prethrombincoagulation activity (increase in prothrombin fragments 1-2 or TATcomplex) with normal D-dimers. Hypercoagulation is characterized by PT andaPTT shortening while fibrinogen and D-dimer are increasing. The incidence ofchemotherapy causes thrombus annually about 11%. The incidence of venousthromboembolism in hospitalized patients receiving chemotherapy in the highThai population, especially in the administration of therapy. To date there havebeen no reports of TEV incidence in lymphoma cancer patients undergoingchemotherapy in Indonesia.Objectives : Assess the activity of coagulation (D-dimers) andcoagulation systems (PT, aPTT, fibrinogen) in non-Hodgkins lymphoma patientsreceiving R-CHOP chemotherapyMethods : Pre and post prospective studies in non-Hodgkinslymphoma patients undergoing chemotherapy with the R-CHOP regimen byconsecutive sampling in the Inpatient Room of Building A RSCM and theInpatient Room of Dharmais Cancer Hospital. The study was conducted in April-June 2019. Patients were taken blood with parameters of coagulation activity (Ddimer)and coagulation system (PT, aPTT, fibrinogen). Data analysis to seechanges in mean pre and post chemotherapy was performed paired t test (normaldistribution) and Wilcoxon test (not normally distributed).Results: A total of 33 patients were included in this study. There was a significantincrease in D-dimer (p: 0.046), PT shortening (0.048) and aPTT (<0.001)significantly, accompanied by a decrease in fibrinogen levels but not statistically significantConclusion : D significantly increased dimer, accompanied bysignificant shortening of PT and aPTT, whereas fibrinogen decreased even thoughit was not statistically significant. This shows the tendency of patients toexperience hypercoagulable state"

"Latar belakang dan tujuan: Salah satu fungsi vitamin D adalah mengatur proliferasi dan maturasi sel darah. Beberapa penelitian membuktikan bahwa terdapat hubungan rendahnya kadar vitamin D dengan kejadian dan kesintasan pada pasien LMA. Data terbaru menunjukkan bahwa prevalensi insufisiensi vitamin D di Indonesia lebih dari 50%, meskipun Indonesia termasuk negara dengan paparan sinar matahari yang tinggi. Keadaan ini kemungkinan juga dialami oleh pasien LMA di Indonesia sehingga dapat memperburuk prognosis penyakitnya. Sampai saat ini belum diketahui secara pasti hubungan kadar vitamin D dengan prognosis pasien LMA di Indonesia. Selain vitamin D, beberapa sitokin yang dipengaruhi oleh vitamin D seperti IL-6 (sitokin proinflamasi) dan IL-10 (sitokin antiinflamasi) dapat mempengaruhi regulasi hematopoiesis normal dan keganasan pada pasien LMA. Penelitian ini bertujuan untuk Mengetahui hubungan antara kadar vitamin D, IL-6, IL-10, dan rasio IL-6/IL-10 dengan kesintasan 1 tahun pasien LMA.Metode: Penelitian dengan desain kohort retrospektif dilakukan pada 43 pasien LMA di RSCM dan RS Kanker Dharmais. Sebanyak 43 serum darah pasien LMA dianalisis dengan metode ELISA untuk memperoleh kadar vitamin D, IL-6 dan IL-10. Analisis kesintasan 1-tahun dilakukan dengan Kaplan Meier estimator.Hasil: Tidak terdapat hubungan antara kadar vitamin D (HR: 0.817 95%CI 0.352-1.901), IL-6 (HR: 1.057 95%CI 0.525-2.128), IL-10 (HR: 0.586 95%CI 0.294-1.168) dan rasio IL-6/IL-10 (HR: 0.823 95%CI 0.411-1.646) serum dengan kesintasan 1-tahun pasien LMA. Tidak ada korelasi antara vitamin D dengan kadar kadar IL-6, IL-10, dan rasio IL-6/IL-10.Kesimpulan: Tidak diperoleh hubungan bermakna antara kadar vitamin D, IL-6, IL-10, dan rasio IL-6/IL-10 dengan kesintasan 1-tahun, namun kami menyadari bahwa besar sampel yang digunakan masih jauh dari cukup. Hasil analisis menunjukkan ada tendensi vitamin D merupakan faktor proteksi pada kesintasan 1 tahun, sedangkan ratio IL-6/IL-10 merupakan faktor risiko pada kesintasan 1 tahun.

Background and aim: Vitamin D was known to the proliferation and maturation of blood cells. Several studies have shown that there is an association between low vitamin D levels with incidences and survivals of AML patients.Previous data had shown that about half of Indonesian have vitamin D insufficiency, even though Indonesia is a tropical country with high sun exposure. Vitamin D insufficiency might also worsen the condition and prognosis of AML patients in Indonesia. Up to date, the relationship between vitamin D levels and the prognosis of AML patients in Indonesia was not known. Several cytokines related to vitamin D, including IL-6 (pro-inflammatory cytokines) and IL-10 (anti-inflammatory cytokines) might also influence the regulation of hematopoiesis in normal and malignant conditions. Thisstudy was aimed to determine the association between vitamin D concentrations, serum IL-6, IL-10 and the ratio of IL-6/IL-10 with 1-year Survival Rate in Indonesian Acute Myeloblastic Leukemia Patients.

Method: This was a retrospective cohort study done in 43 AML patients in RSCM and RS Kanker Dharmais. We analyzed 43 serum samples for vitamin D, IL-6 and IL-10 concentrations using ELISA. Survival analysis was done using Kaplan Meier estimator.

Result: There was no correlation between the levels of vitamin D (HR: 0.817 95%CI 0.352-1.901), IL-6 (HR: 1.057 95%CI 0.525-2.128), IL-10 (HR: 0.586 95%CI 0.294-1.168) and ratio IL-6/IL-10 (HR: 0.823 95%CI 0.411-1.646) with 1 year survival of AML patients. There was no correlation between vitamin D and levels of IL-6, IL-10 and ratio IL-6/IL-10.

Conclusion: There is no correlation between vitamin D, IL-6, IL-10 and ratio IL-6/IL-10 with 1-year survival of AML patients. No association was found between vitamin D, IL-6, IL-10, ratio IL-6/IL-10. However, the study was done in a limited sample size. Analysis showed a tendency for vitamin D to be a protective factor at 1 year survival, while the ratio IL-6/IL-10 was a risk factor at 1 year survival."

"We report three rare cases of mucosal-associated lymphoid tissue (MALT) lymphoma. Two cases are of gastric MALT lymphoma and one is a case of transverse colon MALT lymphoma. The two cases of gastric MALT lymphoma were diagnosed by endoscopy which demonstrated an ulcer in the cardia and another in the corpus. The first case is in a 62-year-old male. The patients medical history revealed upper GI tract bleeding with melaena in 1993. At the time no diagnosis was made on endoscopy In August 2000, melaena recurred and endoscopy showed an ulcer in the cardio. Histology showed high-grade gastric MALT lymphoma. Based on Ann Arbor classification, the patient was classified as stage IE gastrointestinal lymphoma. H. pylori was negative. The patient received chemotherapy The second case is in a 53-year-old male. He suffered from gastric lymphoma for 3 years. He complained of annually recurring haematemesis before a definitive diagnosis was finally established. He suffered jiom stage IE low-grade well-differentiated lymphocytic MALT lymphoma. H. pylori was negative. Endoscopic procedure after H. pylori eradication showed ulcer regression though histology still showed low-grade MALT lymphoma and H. pylori as positive. The third case is in a 46-year-old male with a complaint of haematochezia. Colonoscopy showed intususception due to tumor in the transverse colon. Histologic examination showed chronic colitis and granulomatosa. lnvagination due to colon tumor was reported. Histologic examination of the biopsy specimen showed low-grade small cell lymphocyte-plasmocytoid lymphoma. "
