Expert Consensus on Targeted Therapy of NSCLC with MET Exon 14 Skipping Mutation / 中国肺癌杂志

The mesenchymal-epithelial transition factor (MET) exon 14 skipping mutation is mainly caused by the loss of c-Cbl tyrosine binding site. This mutation could result in a decrease in the degradation rate of proteasome-mediated MET proteins, trigger continuous activation of downstream pathways, and ultimately lead to tumorigenesis. The incidence of MET exon 14 skipping mutation in patients with non-small cell lung cancer (NSCLC) is 0.9% to 4.0%. Patients with advanced NSCLC are recommended to test MET exon 14 skipping mutations who may benefit from MET inhibitors-targeted therapy. MET inhibitors have a high objective response rate and good safety profiles, which could prolong the survival of NSCLC patients with MET exon 14 skipping mutations. The Lung Cancer Specialty Committee of Chinese Elderly Health Care Association organized multidisciplinary experts to give suggestions on the important issues of clinical aspects for targeted therapy of MET exon 14 skipping mutation in NSCLC according to the clinical practice experiences and evidences based medicine. "Expert Consensus on Targeted Therapy of NSCLC with MET Exon 14 Skipping Mutation" is proposed, aiming to provide standardized guidances for the clinical practice of Chinese physicians.

Treatment options after sorafenib failure in patients with hepatocellular carcinoma

Second line therapy after failure of sorafenib continues to be under study. Prognosis of hepatocellular carcinoma is measured in months, with median overall survival reaching 10.7 months with sorafenib. Because of the modest net benefit sorafenib has contributed, and rising incidence of hepatocellular carcinoma in the world, continued efforts are ongoing to look for efficient upfront, second line, or combination therapies. Herein we review the most relevant to date published literature on treatment options beyond sorafenib, reported studies, ongoing investigational efforts, and possibilities for future studies in advanced hepatocellular carcinoma.

Advances on receptor tyrosine kinase inhibitors taking c-Met as anti-tumor target / 中国药科大学学报

@#c-Met receptor tyrosine kinase plays an important role in signaling pathways including cell proliferation, metabolism as well as tumorigenic growth, migration and angiogenesis. c-Met has emerged as an attractive target for cancer therapy. Moreover, the interactive cross-talk between c-Met signaling and several other signaling pathways underlies a key effect for resistance of anti-cancer drugs. Thus, multi-target inhibitors become a new approach to cancer therapy. This paper introduces the c-Met signaling pathway and the resistance of kinase inhibitors caused by the cross-talk between c-Met and other membrane receptors and then will reviews the progress of single-target and multi-target c-Met inhibitors.
