BackgroundMolecular subtypes of breast carcinoma, luminal A like has the best prognosis, but in the previous studies there were cases thatshowed poor clinical outcomes. This study attempted to investigate the clinicopathological characteristics in luminal A like subtypebreast carcinoma.MethodsThis study is a cross sectional study. The samples used were 67 medical records of patients with luminal A like subtype breastcarcinoma in January 2014 to June 2019 period from Hasan Sadikin Hospital, Bandung. According to estrogen receptor (ER) andprogesteron receptor (PR) expression status by adding both intensity and distribution scores, the data were divided into twosubgroups: low histoscore (<7) and high histoscore (≥7). Clinicopathological characteristics (age, TNM stage, treatment, location,histologic type, grading and metastasis) were evaluated for each subgroup.ResultsFrom 67 luminal A like subtype breast carcinoma patients, 73.13% were in the high histoscore subgroup, with higher percentage oflow grade histopathologic features (63.27%). There were no significant differences in age and TNM staging between the twosubgroups. Among 67 breast carcinoma patients, 43 were diagnosed in advanced stages. There were significant differences inlymph nodes metastasis between the two subgroups (p-value 0.013), however, there were no significant difference in metastasis toother organs.ConclusionThis study shows that 73.13% of patients with luminal A like subtype breast carcinoma have a high histoscore of hormone receptor.Low histoscore subgroups luminal A like subtype breast carcinoma will metastasize to lymph nodes.

BackgroundPapillary thyroid carcinoma is the most common subtype among thyroid cancers. The interaction between cancer cells and tumormicroenvironment plays roles in cancer proliferation and invasiveness. One of important components of tumor microenvironmentthat could stimulate tumor proliferation and invasiveness is activated fibroblast, known as carcinoma associated fibroblasts (CAFs).The aim of this research is to analysed FAP expression is associated with clinicopathologic characteristics.MethodsThis retrospective descriptive observational study with serial cases design was conducted in 40 samples of the paraffin blocks oftissues registered in Department of Anantomical Pathology Faculty of Medicine University of Sriwijaya/Dr. Moh. Hoesin PalembangHospital from January 1st, 2017 to October 31st, 2019. All samples were immunostained with FAP antibody. The expressions of FAPwere evaluated in accordance with the results of the previous study. Statistical test was performed by using Chi-square andSpearman-rho statistical test. Statistical analysis was performed by using SPSS version 23.0.ResultsOur data indicated that patients who were ≥45 years old (21 cases; 52.5%), women (31 cases; 77.5%) suffered from this cancer themost. The stromal type found in ten classic, follicular, solid and columnar variance were pauci (25 cases; 62.6%), desmoplastic (8cases;20%), sclerosis (5 cases; 12.5%) and inflammatory (2 cases; 5%). The expression of FAP in tumor stroma has a significantcorrelation with histopathology subtypes (p=0.028) and stromal type (p=0.000).ConclusionFAP was expressed in tumor epithelial cells and fibroblast stromal tumour of papillary thyroid carcinoma. FAP expression in stromaltumor between histopathologic subtype and stromal type showed significant correlation

BackgroundMetastatic adenocarcinoma of unknown origin remains a serious problem in oncology. Pancreatic cancer is often diagnosed when ithas already metastasized. Therefore immunohistochemistry (IHC) examination for detecting metastases of pancreatic origin is veryimportant IHC marker of Pancreatic duodenal homeobox-1 (PDX-1) has a good accuracy for detecting metastases of pancreaticorigin, however it is not readily available in many centers in Indonesia. Instead, IHC marker that is often being used is CK19. Thismarker is not specific, because it is also expressed by gastrointestinal and hepatobilliary tumors. This evidence-based case reportaims to determine the accuracy of CK19 compared with PDX-1 IHC for detecting pancreatic tumor and its metastases.MethodsLiterature searches were conducted on Pubmed/MEDLINE®, Scopus®, Cochrane®databases. Four articles about PDX-1 and 5 articlesabout CK19 that are relevant were found. Those articles were critically appraised.ResultsAll articles are considered valid, as they fulfilled the important criteria for journal validity. A study of CK19 IHC found that this markerhas 100% sensitivity and 6% specificity for diagnosing liver metastases from well-differentiated pancreatic ductal adenocarcinoma.Studies of PDX-1 IHC have different results; a study found that 27 out of 67 were PDX-1 positive in metastases of pancreaticadenocarcinoma origin, while another study found that PDX-1 has 72% sensitivity and 93% specificity for pancreatic neuroendocrinetumor, with 100% sensitivity and 75% specificity for pancreatic neuroendocrine tumor metastases.ConclusionCK19 IHC is highly sensitive for detecting adenocarcinoma metastases of pancreatic origin, thus it can be utilized as a screening test.However, CK19 IHC specificity for detecting adenocarcinoma metastases of pancreatic origin is low compared to PDX-1 IHC

BackgroundTriple negative and positive HER 2 subtype breast carcinoma are aggressive subtype that have worst prognosis among othersubtype. High level of tumor infiltrating lymphocytes (TILs) is associated with longer disease free survival and overall survival.Breast cancer is also influenced by the presence of ligation between PD-1 and PD-L1, expressed by activated CD8+ T cells andtumor cells, consecutively. To analysed the comparison of PD-L1 expression levels in triple negative breast cancer and HER2enriched subtype.MethodsA cross sectional study was conducted with 35 samples, which were immunostained with an anti-PD-L1 antibody. TILs weremeasured on HE slides, and together with PD-L1 expression were calculated using image J. Clinicopathological data were obtainedfrom medical record. All data were analysed by SPSS V25.0ResultsA significant difference was observed between PD-L1 expression in HER2 enriched and triple negative samples, where the HER2enriched subtype had a possibility to express PD-L1 3.3 times higher than those of triple negative (p = 0.021; OR = 3.3). There wereno significant differences in clinopathological characteristics or TILs density in both subtypes. Likewise, no significant differenceswas found among PD-L1 expression, and intratumoral and stromal TILs expression.ConclusionMajority patient of both subtypes are mostly older than 40 years old, with positive LVI and higher histological grading. The HER2expression showed a higher level of PD-L1 than triple negative. There was no significant difference of TILs expression betweenthese two subtypes of breast cancer.

BackgroundNon-small cell lung cancer (NSCLC) is an epithelial carcinoma of the lung which consists of adenocarcinoma, squamous cellcarcinoma (SCC), and large-cell carcinoma (LCC). In a microtumor environment, PD-L1 and PD-1 bonds are immune checkpointsthat act in suppressing the activity of CD8+ TILs, thus affecting the prognosis of NSCLC. Aims of this study is to determine thecorrelation between PD-L1 expression with CD8+TILs in NSCLC.MethodsThis was a cross-sectional study of NSCLC registered in Department of Anatomical Pathology Faculty of Medicine University ofSriwijaya/Dr. Moh. Hoesin Palembang Hospital since 1 January 2017 to 31 January 2020 with a total of 24 samples. All sampleswere immunostained using PD-L1 and CD8 antibodies. PD-L1 expression was assessed in tumor mass and CD8 expression inintratumoral and peritumoral TILs.ResultsOnly two subtypes, adenocarcinoma and SCC, were found in this study. Adenocarcinoma was the most frequent subtype (54.1%),sample group is dominated by <60 years old and was the subtype that expressed the PD-L1 most strongly (TPS ≥50%). There wasnot significant correlation between PD-L1 expression with CD8+ TILs in NSCLC (p=0.679 and p=0.826) but based onclinicopathological characteristics, there was a significant relationship between PD-L1 with disease stage and between intratumoralCD8+ TILs density with disease stage (p=0.048 and p=0.017).ConclusionAdenocarcinoma subtype had stronger expression of PD-L1 compared to SCC. There was no correlation between PD-L1 and CD8+TILs density in NSCLC.

BackgroundSynovial sarcoma is a rare high grade soft tissue sarcoma. Nowdays, the available therapeutic modalities has not given asatisfactory result yet. Currently, there is a promising therapeutic strategy through immunotherapy targeting NY-ESO-1 which isexpressed on tumor. The aim of this study was comparing NY-ESO-1 immunoexpression between synovial sarcoma and itshistologic mimics i.e. malignant peripheral nerve sheath tumor (MPNST) and dermatofibrosarcoma protuberans (DFSP)MethodsA cross sectional study was done in 28 cases of synovial sarcoma, 10 cases of MPNST and 17 cases of DFSP from archievalmaterial in Department Anatomical Pathology, FMUI/RSCM from January 2013 to June 2019. Immunohistohemical stainning wasperformed using an antibody NY-ESO-1 and it was described positive if it was expressed in more than 50% of tumor with moderateto strong positive intensity.ResultsThere is a significant difference (p<0.001) in NY-ESO-1 immunoexpression among synovial sarcoma (18/28), MPNST (2/10) andDFSP (1/17). Furthermore, synovial sarcoma showed a significantly higher immunoexpression compared to MPNST (OR 7.2;p=0.016; power 68.7%) and DFSP (OR 28.8; p<0.001; power 98.9%).ConclusionSynovial sarcoma showed a higher expression of NY-ESO-1 thus makes it as a good candidates for immunotherapy. There aredifferences in the expression of NY-ESO-1 in synovial sarcoma against MPNST and DFSP.
