Abstract

Background: Lung adenocarcinoma patients receiving EGFR-TKI may develop acquired resistance within 7-16 months of treatment initiation, which is characterized by the presence of exon 20 T790M mutations in treatment response patients and can be assessed objectively by CECT and then evaluated by RECIST 1.1. The purpose of this study is to look into the association between acquired resistance EGFR Exon 20 T790M mutation and treatment response in lung adenocarcinoma patients receiving EGFR-TKI. Method: This research is an analytic study with a retrospective cohort design carried out at the Oncology Polyclinic at Haji Adam Malik Hospital from October 2020 to January 2021 in all patients with adenocarcinoma lung cancer who were treated with EGFR-TKI for more than 6 months. After that, an evaluation was carried out based on RECIST 1.1 and then examined for EGFR mutations from liquid biopsy specimens in the form of circulating tumor plasma DNA (ct-DNA) with the droplet digital Polymerase Chain Reaction (ddPCR) method to detect EGFR exon 20 T790M mutations as a marker of acquired resistance. Results: It was found that the majority of subjects were female (64.5%), aged 20-69 years (58%), and non-smokers (67.7%). The most common EGFR mutation was exon 19 deletion (58.1%). The incidence of acquired resistance was found in 10 subjects (32.3%). The distribution of RECIST 1.1 results on positive acquired resistance includes progressive diseases of 35.2%; stable disease of 11.1%; partial response of 33.4%; and 100% complete response. Negative acquired resistance includes 64.8% progressive disease, 88.9% stable disease, 66.6% partial response, and 0% complete response (P=0.93). Conclusion: There is no significant association between the incidence of acquired resistance mutations EGFR exon 20 T790M and treatment response in patients with lung adenocarcinoma who received EGFR-TKI therapy.

Abstract

Background: Nicotine is metabolized to cotinine by cytochrome P450 enzyme, and this enzyme is involved in the activation of toxic and carcinogenic substances. The aim of this research was to assess the relationship between genetic polymorphism of CYP2A13 and lung cancer incidence in female passive smokers.Materials and methods: This research was a case-control study that involved 104 research subjects. Subjects were recruited through purposive sampling technique from 2 hospitals in Medan, North Sumatra, Indonesia. The case population consisted of female passive smokers with lung cancer and the control population consisted of female passive smokers without lung cancer. All research subjects underwent blood sampling for genomics DNA extraction and CYP2A13 genotyping by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Data was analyzed by conditional logistic regression by Epi Info 7.0 software.Results: Among 104 subjects, 26 (25%) individuals were heterozygous, 76 (73%) individuals were wild type, and 2 (2%) were mutant for the 257Cys allele. There was a significant correlation between CYP2A13 genotype and lung cancer incidence (p-value<0.05). Female passive smokers with CT genotype had 2.7 greater risk of developing lung cancer than those with CC genotype (wild type). The C allele had more frequency and 1.6 times higher risk of lung cancer compared to T allele with a wide confidence range (0.73–3.52).Conclusion: There was a significant correlation between CYP2A13 polymorphism and lung cancer incidence in female passive smokers.Keywords: polymorphism, CYP2A13, PCR-RFLP, female passive smoker, lung cancer

Abstract

Background: The major significant factor that affected lung cancer development among female passive smokers is environmental tobacco smoke. Nicotine can be found in a never smoker population, such as a child whose father is a smoker. Lung carcinogenesis in never smoker populations is affected by nicotine metabolism by CYP2A6 gene, which encodes the main nicotine metabolizing-enzyme. The aim of this study was to assess the genetic polymorphism of CYP2A6 and its association with secondhand smokers among females who have suffered from lung cancer in North Sumatra population.Materials and methods: This study was a case-control study, composed of 53 case subjects and 46 control subjects that were involved through a purposive sampling technique from two hospitals in Medan. PCR-RFLP was used for the examination of CYP2A6 gene to determine the genotype. The data were analyzed with conditional logistic regression test using Epi Info 7.0 software.Results: The most common genotype of CYP2A6 detected in this study was *1B/*1B (40.4%), while *1B allele had the highest prevalence (55.5%). There was no significant association between CYP2A6 genotype (p-value=0.61) or alleles (p-value=0.25) and the incidence of lung cancer.Conclusion: There was no association between CYP2A6 polymorphism and the incidence of lung cancer in secondhand smoker females.Keywords: CYP2A6, PCR-RFLP, female secondhand smokers, lung cancer

Abstract

Background: Epidermal growth factor (EGFR) is a transmembrane receptor that plays an important role in the development of cancer phenotypes. Some patients with lung cancer have genetic mutations. Several studies have found a close correlation of EGFR gene mutation with 15-20% of lung adenocarcinoma cases. This study aimed to determine the EGFR profile in adenocarcinoma lung cancer patients at Haji Adam Malik General Hospital.Methods: This was a prospective cohort study conducted at Haji Adam Malik General Hospital, Medan. This study used patients data for 3 years, starting from January 1, 2014 to D1ecember 31, 2016. The sample size in this study was 34 patients. The data were then analyzed using SPSS.Results: All patients were adenocarcinoma lung cancer patients with positive EGFR mutation. There were 9 subjects with EGFR mutation in exon 19; 11 subjects with exon 21 L858R mutation; and 3 subjects with exon 21 L861Q mutation. Meanwhile, there were 3 subjects with uncommon EGFR mutations, namely exon 18 mutation. Majority of subjects with exon 19 mutation were male, aged >60 years, smokers with mixed types of cigarettes and severe brinkmann index. In subjects with exon 21 L858R mutation, most of the patients were male, aged 50-60 years, smokers with mixed cigarette types and severe brinkmann index. The same characteristics were also observed in subjects with exon 18 mutation. However, for exon 21 L861Q mutation, the majority of subjects were female with varying ages, and were not smokers.Conclusion: Most of the study subjects profiles were male, aged over 60 years, smokers, with mixed types of cigarettes, and with severe Brinkman Index. The EGFR mutations most commonly occured in exon 21, followed by exon 19 (ins/del exon 19), exon 18, and a combination of 2 exons.

Abstract

Introduction: Patients with lung adenocarcinoma following epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment will develop acquired resistance after 7 to 16 months of starting the medication, indicated by the emergence of exon 20 T790M mutations. This study aimed to identify the clinical and demographical profile of acquired resistance in patients with lung adenocarcinoma receiving EGFR-TKI therapy through plasma circulating tumor deoxyribonucleic acid (ctDNA) examination. Methods: This was a descriptive study with a retrospective cross-sectional design involving 108 lung adenocarcinoma patients who received EGFR-TKI for more than six months. Exon 20 T790M EGFR mutations were identified as a sign of acquired resistance using the digital droplet polymerase chain reaction (ddPCR) approach to examine plasma ctDNA Utilizing the Statistical Package for the Social Sciences, statistical tests were used to examine the data (SPSS). The data were analyzed by statistical tests using the Statistical Package for the Social Sciences (SPSS). Results: A total of 31 patients were recruited as study participants. The majority of the research subjects were female (64.5%), aged 20-69 years old (58%), and non-smokers (67.7%). Exon 19 deletions were the most prevalent EGFR mutation (58.1%). The incidence of acquired resistance was found in 10 subjects (32.3%). Patients with acquired resistance were predominately female (70%), non-smokers (80%), and with gefitinib therapy (90%). The average time for EGFR-TKI treatment until acquired resistance occurred was 12.6 months. Conclusion: The incidence of acquired resistance was mainly found in women without a smoking history after 12.6 months of treatment with EGFR-TKI.

Abstract

Introduction: Pulmonary embolism is associated with coagulopathy in COVID-19. It is one of the causes of death in COVID-19 cases and is often underdiagnosed in Indonesia because computed tomography-pulmonary angiography (CTPA) is not used as the gold standard. T Methods: This study used a prospective analytical design with a cross-sectional approach. The study participants were 45 COVID-19 patients admitted to Santa Elisabeth Hospital, Medan, from January to March 2021.  Patients were identified with moderate to severe degrees of COVID-19 and elevated D-dimer and subsequently instructed to undergo a thorax CT scan with IV contrast. The data was analyzed using dependent t-test statistical analysis. The p-value < 0.05 was noted as significant. Results: Moderate to severe coagulation factor values in COVID-19 patients with mean + SD PT, APTT, D-dimer, fibrinogen, and platelets were 14.11; 30.65; 1172.14; 423.56 and 215.822, respectively. In this study, 22 (48.9%) patients experienced a pulmonary embolism, while the other 23 (51.1%) did not. No significant correlation was found between all coagulation factors and embolism (p > 0.05). The mean + SD well score for pulmonary embolism was 0.23 + 0.57. Conclusion: Pulmonary embolism was detected in 22 patients (48.49%) with moderate to severe COVID-19 who developed hypercoagulation as indicated by the thorax CT scan with IV contrast. This case was quite common. In resource-constrained situations, a thorax CT scan with IV contrast may replace CTPA in diagnosing/detecting the presence of pulmonary embolism.

Abstract

Introduction: Patients with adenocarcinoma of the lung that have a common EGFR mutation, the Exon 19 Del mutation, survive better than those with the Exon 21 L858R mutation. This study examined whether there is a significant difference in prognosis between two common EGFR mutations, namely exon 19 Del and 21 L858R. This study compared OS (overall survival) and PFS (progression-free survival) in NSCLC patients with Exon 19 Del and Exon 21 L858R mutations who received EGFR-TKI targeted therapy at H. Adam Malik Hospital Medan. Methods: This analysis study used a retrospective cohort design to evaluate the OS and PFS of NSCLC patients who underwent EGFR-TKI precision medicine at H. Adam Hospital Malik Medan between January 1, 2017, and December 31, 2020 and also had Exon 19 Del and Exon 21 L858R alterations. Results: A total of 88 people were sampled. The majority of research subjects were male (60.2%). Median OS was eleven months (95 percent CI:9.594-12,406). According to the study's data, eight people (9.1%) survived until the study's ending. The median OS of Exon 19 Del Common Mutation was 11 months (95%CI 9,064-12,936). While Exon 21 L858R group had ten months (95%CI 4,546-15,454). The log-rank test identified no statistical difference in median OS between mutation types (p=0.562). Conclusion: The findings of this study revealed that subjects with Exon 19 Del mutations had a longer median OS and PFS than those with Exon 21 L858R variants. Nevertheless, there was no significant difference in median OS and PFS between study subjects with mutation of Exon 19 Del and Exon 21 L858R, which received the targeted medication.
