High Aldehyde Dehydrogenase Levels Are Detectable in the Serum of Patients with Lung Cancer and May Be Exploited as Screening Biomarkers.

High Aldehyde Dehydrogenase Levels Are Detectable in the Serum of Patients with Lung Cancer and May Be Exploited as Screening Biomarkers. J Oncol. 2019;2019:8970645 Authors: Rossi A, Voigtlaender M, Klose H, Schlüter H, Schön G, Loges S, Paolini M, Bokemeyer C, Reck M, Tarro G, Binder M Abstract Objectives: Since early detection improves overall survival in lung cancer, identification of screening biomarkers for patients at risk represents an area of intense investigation. Tumor liberated protein (TLP) has been previously described as a tumor-associated antigen (complex) present in the sera from lung cancer patients. Here, we set out to identify the nature of TLP to develop this as a potential biomarker for lung cancer screening. Materials and Methods: Beginning from the peptide epitope RTNKEASI previously identified from the TLP complex, we produced a rabbit anti-RTNKEASI serum and evaluated it in the lung cancer cell line A549 by means of immunoblot and peptide completion assay (PCA). The TLP sequence identification was conducted by mass spectrometry. The detected protein was, then, analyzed in patients with non-small cell lung cancer (NSCLC) and benign lung pathologies and healthy donors, by ELISA. Results: The anti-RTNKEASI antiserum detected and immunoprecipitated a 55 kDa protein band in the lysate of A549 cells identified as aldehyde dehydrogenase isoform 1A1, revealing the molecular nature of at least one component of the ...

AbstractBackgroundIt is known that there are insufficient prognostic factors for non-small cell lung cancer (NSCLC). It was reported that PD-L1 was a prognostic factor for NSCLC,and c-Myc regulated the expression of PD-L1. Herein, we investigated c-Myc and PD-L1 expression and their association with overall survival (OS) in NSCLC.MethodsFormalin-fixed paraffin-embedded specimens were obtained from 128 patients with surgically resected primary NSCLC. Immunohistochemistry was used to assess the expression of PD-L1 and c-Myc in this study. Pearson ’s Chi squared test or Fisher’s exact test was used to analyze the ...

ConclusionsAt the current price of pemetrexed, the combination of pemetrexed plus cisplatin was not found to be a cost-effective first-line regimen for patients with non-small cell lung cancer at the local Thai threshold compared with the gemcitabine plus cisplatin and carboplatin plus paclitaxel regimens.

SharmaAbstractWith the advent of targeted therapies there was a paradigm shift in the treatment of metastatic adenocarcinoma of lung. Immuno-histopathology and molecular subtyping in metastatic adenocarcinoma lung have enabled personalized treatment for each patient. Oncogenic driver mutations in non-small cell lung cancer are commonly EGFR (Epidermal Growth Factor Receptor) gene mutation and ALK (Anaplastic Lymphoma Kinase) gene rearran...

Several anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors have been developed for the treatment of EML4-ALK-rearranged non-small-cell lung cancer, with the newer generation agents brigatinib, alectinib and lorlatinib showing pronounced central nervous system activities. Intracranial efficacy is an important feature for these agents, as metastatic lesions frequently occur in the central nervous system in the ALK-positive setting. Here, we report on an updated case of a patient who received her diagnosis in 2005 and has had disease progression with new lesions on six occasions over the last 8 years. During the firs...

Authors: Wei Z, Li Q, Ye X, Yang X, Huang G, Li W, Wang J, Han X Abstract Objective: To evaluate the efficacy of microwave ablation (MWA) and MWA plus monochemotherapy in elderly patients with advanced non-small-cell lung cancer (NSCLC). Material and methods: Patients with advanced NSCLC aged ≥70 years were retrospectively enrolled. MWA was performed at the primary tumor site. The end points included progression-free survival (PFS), response to MWA and overall survival (OS). Results: Fifty-four patients were enrolled; of these, 36 received monochemotherapy. Complete ablation was achieved in 42 patients (7...

ConclusionsThe efficacy of crizotinib in patients with advanced NSCLC is related to the number of metastatic organs, age and timing of treatment. The use of crizotinib is prone to intracranial progression, and progression of simple brain metastases is not an indication that crizotinib is discontinued. Patients will continue to benefit from combination of local radiotherapy.

Since the discovery of the fact that tyrosine kinase inhibitors could improve progression-free survival for patients with advanced non-small cell lung cancer compared with traditional chemotherapy, it has been extremely important to identify epidermal growth factor receptor mutation status in treatment stratification. Although lack of sufficient biopsy samples limit the precise detection of epidermal growth factor receptor mutation status in clinical practice, and it is difficult to identify the sensitive patients who confer favorable response to tyrosine kinase inhibitors. An increasing number of scholars tried to deal wi...

Worldwide, especially in China, lung cancer accounts to a major cause of mortality related to cancer. Treatment decisions mainly depend on oncogenic driver mutations, which offer novel therapeutic targets for anticancer therapy. However, studies of genomic profiling of driver gene mutations in mainland China are rare. Hence, this is an extensive study of these mutations in Non-small-cell lung cancer (NSCLC) Chinese patients. Comparison of driver gene mutations of lung adenocarcinoma with other races showed that the mutational frequencies were similar within the different East Asian populations, while there were differences...
