Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality around the world. Brain metastasis (BM) is seen in up to 20-40% patients with NSCLC [1,2]. Patients with EGFR mutation have a higher likelihood of BM because of prolonged survival by EGFR tyrosine kinase inhibitors (EGFR-TKIs) [3 –5]. Further, whole-brain radiotherapy (WBRT), stereotactic radiosurgery (SRS) and surgical excision are options for local control, and each shows different treatment benefit in selected subgroups [6].

In the palliative care of patients with non-small cell lung cancer (NSCLC), bronchial hypersecretion (bronchorrhea) may cause additional dyspnea and impaired quality of life. Bronchorrhea is defined as mostly aqueous sputum production with a volume of> 100ml / 24 hours. Various treatment options have been described in case reports and small series, including the use of tyrosine kinase inhibitors such as gefitinib and erlotinib, somatostatin analogues (octreotide), macrolide antibiotics, anti-inflammatory drugs (indomethacin, corticosteroids) and anticholinergics.

This study aimed to investigate the feasibility of fitting dual-input tracer kinetic models to DCE-MRI datasets of thoracic malignancies, including malignant pleural mesothelioma (MPM) and nonsmall cell lung cancer (NSCLC), by comparing them to single-input (pulmonary or systemic arterial input) tracer kinetic models for the voxel-level analysis within the tumor with respect to goodness-of-fit statistics. Fifteen patients (five MPM, ten NSCLC) underwent DCE-MRI prior to radiotherapy. DCE-MRI data were analyzed using five different single- or dual-input tracer kinetic models: Tofts-Kety (TK), extended TK (ETK), two compartm...

Authors: Wu L, Zhang W, Qian J, Wu J, Jiang L, Ling C Abstract The R-spondin (RSPO) family of secreted proteins consists of four members that have critical roles in embryonic development and organogenesis. However, the expression patterns and the exact roles of the individual RSPO family members in tumorigenesis and progression of lung cancer are unknown, particularly in non-small cell lung cancer, which accounts for 85% of all lung cancer cases. In the present study, data from the ONCOMINE database was used to compare the RNA expression levels of RSPOs in multiple different types of cancer with normal controls. Th...

Authors: Jin C, Song P, Pang J Abstract Lung cancer negatively impacts global health, and the incidence of non-small cell lung cancer (NSCLC) is highest among all forms of lung cancer. Chemotherapy failure mainly occurs due to drug resistance; however, the associated molecular mechanism remains unclear. Casein kinase II (CK2), which plays important roles in the occurrence, development and metastasis of many tumours, regulates Wnt signaling by modulating β-catenin expression. In the present study the effects of the CK2 inhibitor, CX4945 on cisplatin [or cis-diamminedichloroplatinum (II); (DDP)]-resistant A549 c...

In 2007, the first anaplastic lymphoma kinase (ALK) fusion was described in non-small cell lung cancer (NSCLC)[1]. In 2013, a phase 3 study demonstrated a significant improvement in progression free survival (PFS) and overall survival (OS) in patients with metastasized ALK positive lung cancer treated with crizotinib compared to chemotherapy[2]. Subsequently, testing for ALK aberrations in patients with metastasized adenocarcinoma of the lung was recommended by international guidelines [3,4].
