  • Introduction: Lung cancer is one of the most common cancers worldwide. In certain countries such as United States of America, it is the leading cause of related cancer mortality among both men and women. Natural products play an important role in overcoming the limitations of chemotherapy and radiotherapy. Objectives: In this study, we investigated the antiproliferative and apoptotic activities of Kanahia laniflora methanolic extract against human non-small cell lung cancer cells (A549). Methods: Sulforhodamine B colorimetric assays were used to determine the inhibitory effects of a leaf methanolic extract against A549 cells. Results: The extract showed strong cytotoxic activity against A549 cells with an $IC_{50}$ value of $0.13{\mu}g/ml$ compared to $0.21{\mu}g/ml$ for doxorubicin. The extract also significantly increased the percentage of apoptotic cells to 49.7% as compared to 1.4% and 47.4% for control and doxorubicin respectively. Conclusion: These results showed, for the first time, that a methanolic extract of Kanahia laniflora leaves can inhibit the proliferation of human non-small cell lung cancer cells (A549). Further attention to its potential as a new effective anticancer agent is warranted.

  • Objective: Molecular pathology tests are often carried for clinicopathological diagnosis and pathologists have established large collections of formalin-fixed, paraffin-embedded tissue (FFPE) banks. However, extraction of DNA from FFPE is a laborious and challenging for researchers in clinical laboratories. The aim of this study was to compare two widely used DNA extraction methods: using a QIAamp DNA FFPE kit from Qiagen and a Cobas Sample Preparation Kit from Roche, and evaluated the effect of the DNA quality on molecular diagnostics. Methods: DNA from FFPE non-small cell lung carcinoma tissues including biopsy and surgical specimens was extracted with both QIAamp DNA FFPE and Cobas Sample Preparation Kits and EGFR mutations of non-small cell lung carcinomas were detected by real-time quantitative PCR using the extracted DNA. Results and Conclusion: Our results showed that DNA extracted by QIAamp and Cobas methods were both suitable to detect downstream EGFR mutation in surgical specimens. Howover, Cobas method could yield more DNA from biopsy specimens, and gain much better EGFR mutation results.

  • For advanced non-small-cell lung cancer (NSCLC) cases, a platinum-based regimen is the first-line chemotherapy treatment. The excision repair cross-complementing group 1 (ERCC1) plays an important role in DNA repair and has been related to resistance to platinum chemotherapy. This study aimed to investigate the effects of the ERCC1 (C118T) polymorphism on treatment response in 26 Thai advanced NSCLC patients receiving first line platinum-based chemotherapy during January to July 2015 at King Chulalongkorn Memorial Hospital (KCMH). DNA was extracted from peripheral blood lymphocytes and the single nucleotide polymorphism of ERCC1 was genotyped using a real-time PCR method with the TaqMan assay. The distribution of C/C, C/T and T/T genotypes was 57.7 %, 34.6 % and 7.7 %, respectively. The response rate to platinum-based chemotherapy in the wild type (C/C) of ERCC1 (C118T) was better than with the variant types (C/T and T/T) but the difference was not statistically significant (29.7% vs 9.1%, P=0.274). The results showed that a genetic polymorphism in ERCC1 might influence patient response to platinum-based chemotherapy. Further multicenter studies are now required to confirm the results of our study.

  • Non-small cell lung cancer harboring epidermal growth factor receptor (EGFR) sensitizing mutations has a distinct disease entity. Patients with this cancer have better prognosis, and frequently achieve long-term survival. EGFR-tyrosine kinase inhibitor (TKI) is the drug of choice for this cancer; but the disease inevitably progresses, after durable response. The tumor is a mixture of EGFR-TKI sensitive clones and resistant clones, regardless of their molecular mechanisms. EGFR-TKI sensitive clones are very susceptible to this drug, but rarely eradicated; so, withdrawal of the drug permits rapid regrowth of drug sensitive clones, possibly causing "disease flare." Re-administration or continuation of EGFR-TKI can effectively suppress the expansion of drug sensitive clones, even when the total tumor volume continuously increases. Chemotherapy can definitely prolong the survival of patients experiencing EGFR-TKI failure. Prospective clinical trials are warranted to compare efficacies of chemotherapeutic agents. A few retrospective studies suggested that a taxanebased regimen may be superior to others. Here, we reviewed therapeutic options and clinical evidence about this unique disease entity.

  • Epidermal growth factor receptor (EGFR) is considered to be one of the key driver genes in non-small cell lung cancer (NSCLC). Several clinical trials have shown great promise of EGFR tyrosine kinase inhibitors (TKIs) in the first-line treatment of NSCLC. Many advances have been made in the understanding of EGFR signal transduction network and the interaction between EGFR and tumor microenvironment in mediating cancer survival and development. The concomitant targeted therapy and radiation is a new strategy in the treatment of NSCLC. A number of preclinical studies have demonstrated synergistic anti-tumor activity in the combination of EGFR inhibitors and radiotherapy in vitro and in vivo. In the present review, we discuss the rationale of the combination of EGFR inhibitors and radiotherapy in the treatment of NSCLC.

  • Objectives: To study variation in T lymphocyte subgoups and its clinical significance in non-small cell lung cancer (NSCLC). Methods: Levels of CD3+, CD4+, CD8+, CD4+/CD8+, NK and Treg cells in peripheral blood of NSCLC cases and healthy adults were determined by flow cytometry. Results: CD3+, CD4+ and CD4+/CD8+ ratio and NK cells in NSCLCs were decreased significantly in comparison with the control group (P < 0.01), and decreased with increase in the clinical stage of NSCLC, while CD8+ cells demonstrated no significant change (P > 0.05). Treg cells were significantly more frequent than in the control group (P < 0.01), and increased with the clinical stage of NSCLC. Conclusion: The cellular immune function of the NSCLC patients is lowered. It is important to detect change of T lymphocyte subgroups by flow cytometry for the diagnosis, treatment and prognostic assessment of NSCLC patients.

  • Lung cancer is a serious health problem and leading cause of death worldwide due to its high incidence and mortality. More than 80% of lung cancers feature a non-small cell histology. Over few decades, systemic chemotherapy and surgery are the only treatment options in this type of tumor but due to their limited efficacy and overall poor survival of patients, there is an urge to develop newer therapeutic strategies which circumvent the problems. Enhanced knowledge of translational science and molecular biology have revealed that lung tumors carry diverse driver gene mutations and adopt different intracellular pathways leading to carcinogenesis. Hence, the development of targeted agents against molecular subgroups harboring critical mutations is an attractive approach for therapeutic treatment. Targeted therapies are clearly more preferred nowadays over systemic therapies because they target tumor specific molecules resulting with enhanced activity and reduced toxicity to normal tissues. Thus, this review encompasses comprehensive updates on targeted therapies for the driver mutations in non-small cell lung cancer (NSCLC) and the potential challenges of acquired drug resistance faced i n the field of targeted therapy along with the imminent newer treatment modalities against lung cancer.

  • Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Standard treatment such as chemotherapy, radiotherapy, and surgery have many limitations in the treatment of this disease. Therefore, new molecular-targeted therapies needed and being developed. Patients with advanced NSCLC have a short life expentancy; therefore, in addition to increasing their survival, improving their quality of life (QoL) is also an important treatment goal. In this case report, we introduce NSCLC patient treated with Allergen Removed Rhus Verniciflua Stokes(aRVS). In this case, survival time incresed as traditional korean medicine using aRVS. And the general condition of the patient became better. Further case study will be needed in order to determine the effects of aRVS on NSCLC.
