To examine the serum levels of carcinoembryonic antigen (CEA), cytokeratin-19 fragments (CYFRA21-1), neuron-specific enolase (NSE), carbohydrate antigen (CA) 19-9, CA125, tissue polypeptide antigen (TPA), tissue polypeptide specific antigen (TPS), and lactate dehydrogenase (LDH) to predict de novo metastatic lung adenocarcinoma.
Multiplex reverse transcription-polymerase chain reaction (RT-PCR) was used to detect KIF5B-RET and CCDC6-RET fusions from specimens of malignant pleural effusion (MPE) in patients with metastatic lung adenocarcinoma.
The 4 most significantly deregulated miRNAs (miR-145, miR-214, miR-9* and miR-1471) were validated in the additional 43 samples (35 primary and 8 brain metastatic lung adenocarcinoma samples) using TaqMan quantitative PCR.
Between June 2014 and May 2015, 168 plasma samples were collected monthly from 20 patients with metastatic lung adenocarcinoma with epidermal growth factor receptor (EGFR) mutation receiving gefitinib therapy.
In the current study, the authors evaluated their experience with the identification of epidermal growth factor receptor (EGFR), Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation, and anaplastic lymphoma kinase (ALK) gene rearrangement using cytological specimens of primary and metastatic lung adenocarcinoma.
Successful treatment of a patient with Li-Fraumeni syndrome and metastatic lung adenocarcinoma harboring synchronous EGFRL858R and ERBB2 extracellular domain S310F mutations with the pan-HER inhibitor afatinib.
The studies, phase III study of afatinib or cisplatin plus pemetrexed in patients with metastatic lung adenocarcinoma with EGFR mutations (LUX-Lung 3) and a randomized, open-label, phase III study of BIBW 2992 versus chemotherapy as first-line treatment for patients with stage IIIB or IV adenocarcinoma of the lung harbouring an EGFR activating mutation (LUX-Lung 6) investigated first-line afatinib versus platinum-based chemotherapy in epidermal growth factor receptor gene (EGFR) mutation-positive patients with NSCLC and included patients with brain metastases; prespecified subgroup analyses are assessed in this article.
We identified oncogenic and drug-sensitive EGFR-KDD that is recurrent in lung, brain, and soft-tissue cancers and documented that a patient with metastatic lung adenocarcinoma harboring the EGFR-KDD derived significant antitumor response from treatment with the EGFR inhibitor afatinib.
Our study confirmed the efficacy and safety of first line erlotinib monotherapy in Caucasian patients with locally advanced or metastatic lung adenocarcinoma carrying activating EGFR mutations based on the screening with the approved companion diagnostic procedure.
