Abstract

BackgroundDiffuse Large B Cell Lymphomas (DLBCL) is divided into two subtypes, GCB and non-GCB, which are determined based on Hans'salgorithm. The GCB subtype has a better prognosis than non-GCB. Some studies indicate that the tumor progression wasinfluenced by tumor microenvironment, including CD8+ TILs located both surrounding tumor cells and peripheral. This study aims todetermine the density of CD8+ TILs in the tumor microenvironment of DLBCL subtypes.MethodsA Cross sectional study of 40 samples of DLBCL registered to Department of Anatomical Pathology Faculty of Medicine UniversitasSriwijaya/Dr. Mohammad Hoesin Palembang Hospital from 1st October 2017 to 31st December 2018. All samples were stained usinganti-CD8 antibody, afterward, lymphocytes express CD8 were assessed both in surrounding tumor cells and peripheral. The densityof CD8 in each DLBCL subtype was analyzed statistically using Mann Whitney U Test.ResultsIn this study, non-GCB subtype was found higher in comparison to GCB subtype (72.5%) and the samples was dominated by youngages (75%). Significantly, peripheral CD8 density was higher than that of surrounding tumor cells, both in the GCB (p=0.003) andnon-GCB subtypes (p=0.000).ConclusionIn both subtypes, CD8 density is higher in peripheral than surrounding tumor cells and a high density in surrounding tumor cells willbe followed by an increase in peripheral CD8 density.

Abstract

BackgroundEpithelial ovarian carcinoma is the most common cause of death among gynecological malignancies in the women. The interactionamong cancer cells and tumor microenvironment plays roles in cancer proliferation and invasiveness. One of important component oftumor microenvironment that could stimulate tumor proliferation and invasiveness, is fibroblast. Activated fibroblasts also known ascarcinoma associated fibroblasts (CAFs). The purpose of research is to analyzed FAP expressions to clinicopathologic characteristic(histopathology subtype and clinical stadium of FIGO) and chemotherapeutic responses.MethodsThis study is a retrospective observational analytic study with cross-sectional designs was undertaken during January 1, 2016 to June30, 2018. The sample was 55 paraffin block sample epithelial ovarian carcinomas consists of 11 samples for each histopathologysubtype collected used purposive sampling technique. All samples were immunostained with FAP antibody. FAP expressions wasevaluated based on Min Shi et al studies. It analyzed stained area/ proportion (P) and intensity (I). Statistical analysis using chi-squarewas performed using SPSS version 17.ResultsPatients of 40-49 years old (24; 43.6%), clinical stadium is III (30; 54.5%), Complete response (CR) of chemotherapeutic response(38; 69.1%). The statistic analyses between histopathology subtypes (p=0.038), clinical stadium of FIGO (p=0.000) and chemotherapyresponse (p=0.000) showed significant differences.ConclusionFAP expressions could showed correlation between clinicopathologic characteristic (histopathology subtype and clinical stadium ofFIGO) and chemotherapeutic response.

Abstract

BackgroundOsteosarcoma is the most common primary malignant bone tumor in children and young adult. Its pathogenesis has been linked toalterations in several genes. The high percentage is found involving Retinoblatoma (RB) pathway. p16 plays as a tumor suppressorin RB pathway to controll proliferation of the tumor cell. The degree of neoadjuvan chemotherapy histological necrosis response isrelated to prognosis of patients with osteosarcoma. Chemotherapy and p16 both synergic in inhibit the cell tumor proliferation andsupport apoptotic. Loss of p16 function is related to progressiveness of the tumor. The aim of this study was to investigate therelationship of p16 expression in pretreatment osteosarcoma to pathologic necrotic histological response after neoadjuvanchomotherapy.MethodsThis is a cross sectional study p16 stainning was done and count the positive expression tumor cell in percentage. Positive wasdefined as strong and medium nuclear stainning in 30% or greater. The samples is catagorized into positive and negative expressionthen it is correlated into tumor necrotic area based on grade of Huvos.ResultsSamples consist of 33 cases. Positive stainning was found in 10 cases (30.3%), 6 of 10 cases had good chemotherapy response.Negative stainning was found in 23 cases and 21 of 23 cases had poor chemotherapy response. A significant association was notedbetween p16 expression and histological necrotic response to neoadjuvan chemotherapy (p=0.004).ConclusionThe result showed that p16 expression associate significantly with histological necrotic response to neoadjuvan chemotherapy inconventional osteosarcoma (p=0.004).

Abstract

BackgroundThe development and aggressiveness of tumor cells were influenced by tumor microenvironment. Tumor-Associated-Macrophages(TAMs) and Tumor-Associated-Neutrophils (TANs) are components of tumor microenvironment, contribute to development and growthof tumor cells. The aim of this research was to analyse correlation of TAMs and TANs densities with clinicohistopathologiccharacteristics of patients i.e. age, gender, location, and subtype.MethodsA case series was conducted. The samples were paraffin blocks of Hodgkin lymphoma patients at Anatomic Pathology DepartmentFaculty of Medicine Universitas Sriwijaya/RSUP Dr. Mohammad Hoesin Palembang. Among 44 cases of Hodgkin lymphomadiagnosed from 1stJanuari 2015 to 30th October 2019, only 31 cases were included. Immunohistochemistry was performed by usinganti-CD163 antibody and neutrophils were identified by morphologic appearances. The results were correlated to characteristicfactors. Statistical analysis was performed using Spearman and Lambda test with significant consideration if p<0.05.ResultsThe study results showed 30 cases of classical Hodgkin lymphoma (CHL) and 1 case of NLPHL. CHL has only 3 variants LR(lymphocyte-rich) (60%), MC (mixed-cellularity) (26.7%), and NS (nodular sclerosis) (13.3%). Hodgkin lymphoma is most commonlyfound in males (61.3%). Tumor were mostly found in the head and neck, and patient ages were majority in the age group 20-29 years,40-49 years, and over 50 years. Spearman test showed there was a significant correlation between density of TAMs with ages(p=0.043).ConclusionHigh density of TAM was correlated with age, however, there was no correlation between TAN and clinicohistopathologiccharacteristics of Hodgkin lymphoma.

Abstract

BackgroundPapillary thyroid carcinoma is the most common endocrine gland malignancy that has the highest incidence rate of 60-80%. In papillarythyroid carcinoma BRAF V600E mutation plays an important role in carcinogenesis. BRAF V600E is a RAS-regulated-serine-threoninekinase and activator of the MAPK pathway cascade that functions to regulate cell proliferation, differentiation and survival. BRAFV600E mutations in PTC is associated with a high incidence of recurrence and reduced survival. The purpose of this study is to lookat the relationship of BRAF V600E expression with histopathological variants and lymphocyte infiltration in PTC.MethodsThis research was a retrospective observational cross sectional study with 40 cases of papillary thyroid carcinoma which werediagnosed in 4 Pathology Anatomy Laboratory in West Sumatera. Samples were obtained from paraffin blocks of tissue from surgeryand were reevaluated for histopathological variant and lymphocyte infiltration. Expression of BRAF V600E in tumor cell were analyzedusing immunohistochemistry staining. Bivariate statistical analysis of Chi-Square were used and p value <0,05 were consideredsignificance.ResultsPositive BRAF V600E expression was found in 24 case (60%). Positive BRAF V600E expression was mostly found in classic PTC(50%). Papillary thyroid carcinoma with lymphocyte infiltration mostly found with negative BRAF V600E expression (79.2%). Statisticalanalysis showed no significant correlation between BRAF V600E with histopathological variant (p=0.74) and no significancecorrelation between BRAF V600E expression with lymphocyte infiltration (p=0.12).ConclusionThe conclusion is BRAF V600E expression has no correlation with histological variants in papillary thyroid carcinoma and no significantcorrelation of BRAF V600E expression with lymphocyte infiltration.

Abstract

ABSTRACTEvaluation of changes in antibody orders is a common exclusion in vaccination strategies because of the method ofanalysis. The fact that protection by antibodies produced by the Severe Acute Respiratory Syndrome Coronavirus-2(Sars-Cov-2) infection both naturally and through vaccines will decrease in less than one year, is a challenge for acountry with a large population like Indonesia to run its vaccination program. The main challenge is whether thevaccination strategy adopted will overcome the vaccine barrier and the race between the rate of vaccination and therate of viral mutation and antibody reduction. In addition to antibodies, the adaptive immune system is also run by Tcells that are included in the cell-mediated immune system (CMI) group. In patients with asymptomatic or mildsymptoms of Coronavirus 2019 (Covid-19), T and CMI responses are known to appear in some patients who are notknown to have been exposed to Sars-Cov-2 before. This evidence suggests that the adaptive catastrophe for SarsCov-2 has been acquired by ordering memory T cells and may last longer than previously thought. For countries withlarge populations, this will certainly help overcome the limitations of vaccines and the time needed to implement theirvaccination strategies.
