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.
