Abstract

Backgrounds: In recent years, circulating tumor DNA (ctDNA) has emerged as a specific and sensitive blood-based biomarker to detect EGFR mutations. This study aims to determine the diagnostic accuracy of ctDNA in detecting EGFR gene mutations in adenocarcinoma lung cancer. Methods: This study was a cross-sectional study with the subjects were adenocarcinoma lung cancer patients from histopathology or cytology examination and examined EGFR mutations from plasma tissue biopsy and ctDNA specimens from April 2018 to February 2019 in several hospitals in the Medan City. Results: There were 100 data have been collected, with male were 71 subjects and female were 29 subjects. Found 20 mutations, single mutations of tissue biopsy were 19 cases, del exon 19 were 12 cases, mutation in exon 21 (L858R) were 6 cases, mutation exon 21 (L861Q) was 1 case, del exon 19 and 21 (L861Q double mutations) was 1 case. From plasma ctDNA examination EGFR mutations were found 15 cases, del exon 19 were 12 cases and del exon 21 (L858R) were 3 cases. Conclusions: The highest proportion of EGFR mutations by sex were women from tissue biopsy or ctDNA, the most often frequency of EGFR mutations from tissue biopsy and ctDNA in single mutations and exons19.

Abstract

Background: Microsomal epoxide hydrolase 1 (EPHX1) plays an important role in both activation and detoxification of polycyclic aromatic hydrocarbons (PAH) and aromatic amines. Polymorphism EPHX1 His139Arg in susceptibility to lung cancer has been reported with inconsistent outcomes. Aim of this study was to analyze the relationship between this polymorphism and lung cancer in smokers.Method: Consecutive sampling and case-control study was applied. Genotyping was performed by PCR-RFLP assay. The chi-square test with p<0.05 considered as significant.Results: Of all 84 subjects, in case and control groups, wild-type variant His139His were 34 (81%) and 30 (71.4%), heterozygote variant His139Arg were 8 (19%) and 12 (28.6%), there was no homozygote variant Arg139Arg identified. (p=0.36).Conclusion: The EPHX1 His139His represents a common polymorphism in both of subject groups. There is no association between His139Arg polymorphism of EPHX1 and 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

Background: Increased number of intrathoracic malignancy cases (Lung tumor, Mediastinum tumor, Secondary lung cancer and Chest wall tumor) contribute in increased complications of respiratory emergencies such as superior cava vein yyndrome (scvs), massive malignant pleura effusion (mpe), central airway obstruction (cao), massive hemoptysis, lung thromboembolism and pneumothorax. This study aims to look at the proportions, outcomes, and factors that influence respiratory emergency in intrathoracic malignancy cases.Methods: This was a retrospective case series of inpatient respiratory emergencies in patients intrathoracic malignancy at H. Adam Malik Central General Hospital - Medan from 1 May 2011 to 30 April 2016.Results: From 690 subjects intrathoracic malignancy, there were 137 (19.8%) patients with respiratory emergencies and mostly caused by lung tumors (83.9%). Massive MPE was is the most common emergency of 45 cases (6.5%) and massive haemoptysis of at least 4 cases (0.6%). The risk of death was higher in patients with respiratory emergencies. Mediastinum and location of tumor contribute in respiratory emergency appearance with respective OR of 3.9 and 1.5 (p value <0.005)Conclusions: Increased of mortality rate in patients with respiratory emergency and MPE massive is the most cases. Type of the malignancy and Right lung tumor contribute of respiratory emergency in intrathoracic malignancy cases.
