Small-cell lung cancer (SCLC) accounts for 13% of all lung tumours. The standard treatment in patients with limited-stage disease is radiotherapy combined with chemotherapy. In extensive SCLC, the importance of consolidation thoracic radiotherapy in patients with a good treatment response has become increasingly recognized. In both limited and extensive disease, prophylactic cranial irradiation is recommended in patients who respond to treatment. New therapeutic approaches such as immunotherapy are being increasingly incorporated into the treatment of SCLC, although more slowly than in non-small cell lung cancer (NSCLC)...

OBJECTIVE: Resistance to glucocorticoid (GC) is a significant clinical problem in some cases of acute lymphoblastic leukemia (ALL). Current methods of assessing GC resistance are time consuming and have limited reproducibility; in this study, we sought to define a new method of evaluating GC sensitivity and resistance in vitro. METHODS: Based on the mechanisms of GC resistance, we hypothesized that the dual-luciferase report (DLR) assay could reflect the transcription effects of GC downstream of the GC-glucocorticoid receptor signaling pathway, thereby allowing the evaluation of reactions to GC...

The immune system regulates angiogenesis in cancer by way of both pro- and antiangiogenic activities. A bidirectional link between angiogenesis and the immune system has been clearly demonstrated. Most antiangiogenic molecules do not inhibit only VEGF signaling pathways but also other pathways which may affect immune system. Understanding of the role of these pathways in the regulation of immunosuppressive mechanisms by way of specific inhibitors is growing. Renal cell carcinoma (RCC) is an immunogenic tumor in which angiogenesis and immunosuppression work hand in hand, and its growth is associated with impaired antitumor immunity...

PURPOSE: Circulating tumor cells (CTCs) with epithelial-to-mesenchymal transition (EMT) phenotypes might be related to tumor progression while OCT4 expression is involved in tumor metastasis and poor prognosis. But the possible clinical significance of EMT phenotypes of CTCs from non-small-cell lung cancer (NSCLC) patients has still to be demonstrated. Furthermore, none has been investigated the expression of OCT4 in CTCs. We therefore identified the EMT phenotype-based subsets of CTCs and determined the OCT4 expression status of CTCs in NSCLC patients, to explore their possible clinical relevance...
