Abstract

Tumors or neoplasms are abnormal solid lesions that form due to improper cell growth, and cancer is a malignant tumor. Cancer has a high potential to damage surrounding organ tissue and metastasize to other organs. Risk factors for any cancer are free radicals, secondary lifestyle, lack of healthy food, and exposure to radiation. Cancer has high morbidity and mortality. And death due to late detection, and the lack of knowledge of most people about this disease, for example, early manifestations, what to do when finding a lump on the body, tests that can be done and early detection of cancer, and others, could be the main reasons. The education is aimed at the general public to provide an overview of organ health and efforts to prevent cancer with examination and safety procedures in the era of the COVID-19 pandemic. The implementation of this outreach is able to increase public knowledge about the importance of early cancer screening. Apart from that, educating the public about cancer and early detection can increase public knowledge about cancer and self-examination for early detection procedures.

Abstract

Background Colorectal carcinoma has several pathways that play a role in normal colonic mucosa development into carcinoma, one of microsatellite instability (MSI) pathway. This pathway results from a deficiency in one of the MMR proteins that normally repair genome damage, leading to microsatellite instability high (MSI-H) and excessive mutations. MSI-H is closely associated with Lynch syndrome and often experiences resistance to chemotherapy treatment, one of which is 5-fluorouracil (5-FU), so it is necessary to conduct initial screening in colorectal carcinoma to assess MMR status on patient with Lynch syndrome . This study aims to see relationship between MMR status and chemotherapy response in colorectal carcinoma. Methods This study is cross sectional study using 30 archival block and slaid samples of all colorectal carcinoma cases from hemicolectomy and biopsy results that have been histopathologically diagnosed in Anatomic Pathology Section of Faculty of Medicine Unsri/RSMH Palembang January 2017-December 2021. Each sample was immunohistochemically stained using four antibodies namely anti-MLH1, anti-MSH2, anti-MSH6 and anti-PMS2 (ventana). Interpretation was qualitative by assessing cell positivity. Categorized into intact and missing with cut-off point value of >10% positive declared intact. MMR deficiency was considered if there was loss of cell positivity, at least one MMR CPI marker and MMR proficiency if all MMR CPI were intact. Analysis of relationship between MMR status and chemotherapy response was performed using Fisher's exact test. Results Fisher's exact test showed an association between MMR status and chemotherapy response. The results were significantly significant with p-value of 0.045 where MMR deficiency status had a 6 times chance of not responding to chemotherapy compared to MMR proficiency. There was no association between MMR status and age, gender, histopathological subtype and tumor location with p-values of 0.139, 1.000, 0.657 and 0.174 respectively. Conclusion There was a significant association between MMR status and chemotherapy response.

Abstract

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.
