Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. The systemic antitumor therapy of advanced NSCLC has undergone renovations of chemotherapy, targeted therapy and immunotherapy, which results in greatly improved survival for patients with advanced NSCLC. Immune checkpoint inhibitors (ICIs), especially targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1), has changed the treatment paradigm of NSCLC. ICIs have become the standard treatment for advanced NSCLC without epidermal growth factor receptor(EGFR) mutation or anaplastic lymphomakinase(ALK) translocation in the first- or second-line setting, and for locally advanced NSCLC following concurrent radiotherapy and chemotherapy. ICIs are also promising in adjuvant/neoadjuvant therapy. More and more ICIs have been approved domestically for the treatment of NSCLC. Led by the NSCLC expert committee of Chinese Society of Clinical Oncology (CSCO), this consensus was developed and updated based on thoroughly reviewing domestic and foreign literatures, clinical trial data, systematic reviews, experts' discussion and the consensus(2019 version). This consensus will aid domestic clinicians in the treatment of NSCLC with ICIs. [ABSTRACT FROM AUTHOR]

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer, most NSCLC patients are at advanced stage at the time of diagnosis. For patients without sensitive driven-oncogene mutations, chemotherapy is still the main treatment at present, the overall prognosis is poor. Improving outcomes and obtaining longterm survival are the most urgent needs of patients with advanced NSCLC. In recent years, immunotherapy has developed rapidly. Immune checkpoint inhibitors (ICIs), especially targeting programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1), have made a breakthrough in the treatment of NSCLC, beneficial to patients' survival and changed the treatment pattern for NSCLC. It shows more and more important role in the treatment of NSCLC. Led by NSCLC expert committee of Chinese society of clinical oncology (CSCO), relevant experts in this field were organized. On the basis of referring to domestic and foreign literature, systematically evaluating the results of Chinese and foreign clinical trials, and combining the experiences of the experts, the experts group reached an agreement to develop this consensus. It will guide domestic counterparts for better application of ICIs to treat NSCLC. [ABSTRACT FROM AUTHOR]

Over the past three decades, business managers and academic researchers have shown considerable interest in understanding how information systems (IS) can lead to competitive advantages for firms. Although in the United States researchers have found that IS competences lead to competitive advantages, it remains unknown whether firms working in emerging economies can capitalize on IS competence for competitive advantages. This article examines the moderating effect of the learning intensity of organizations on the relationship between IS competence and competitive advantages in 122 Chinese firms. Data were collected from a mailed survey of 122 information-technology (IT) managers. The results indicate that flexibility of IT infrastructure, IT business skills, and learning intensity have significant effects on competitive advantages. The learning intensity of organizations positively moderates the relationship between IS business skills and competitive advantages, but has no moderating effect on the relationship between the flexibility of IT infrastructure and competitive advantages.

Background and objective Lung cancer in young patients (less or equal to 45 years) is relatively rare. We explored the efficacy and survival of Gefitinib for young patients with unknown epidermal growth factor receptor (EGFR) gene mutation of advanced lung adenocarcinoma. Methods The clinical data of 55 young patients with unknown EGFR gene mutation in advanced lung adenocarcinoma referred to the Cancer Hospital & Institute, Chinese Academy of Medical Sciences from Jan 2006 through Dec 2010 were analyzed retrospectively. Results Of 55 young patients enrolled, the median age was 41 years. The objective response rate and disease control rate were 43.6% and 90.9%, respectively.. The median progression-free survival (PFS) was 9.0 months. Among the factors analyzed, brain metastasis had significant effect on PFS (P=0.017). The median overall survival (OS) was 24.0 months. The independent prognostic factors to significantly improve OS included non-smoking history (P=0.028) and receiving other anti-cancer treatment after Gefitinib therapy (P<0.001). Conclusion The median PFS and OS of the young patients with Unknown EGFR gene mutation in advanced lung adenocarcinoma were similar with general population. [ABSTRACT FROM AUTHOR]
