Comparison of different methods for detecting epidermal growth factor receptor mutations in peripheral blood and tumor tissue of non-small cell lung cancer as a predictor of response to gefitinib.

OncoTargets and therapy

Xu F, Wu J, Xue C, Zhao Y, Jiang W, Lin L, Wu X, Lu Y, Bai H, Xu J, Zhu G, Zhang L.
PMID: 23251095
Onco Targets Ther. 2012;5:439-47. doi: 10.2147/OTT.S37289. Epub 2012 Dec 12.

BACKGROUND: Previous studies have reported that epidermal growth factor receptor (EGFR) mutation in tumor tissue and peripheral blood can predict the response to EGFR tyrosine kinase inhibitor (TKI) in non-small cell lung cancer (NSCLC). However, the heterogeneity of the...

Cisplatin combined with irinotecan or etoposide for untreated extensive-stage small cell lung cancer: A multicenter randomized controlled clinical trial.

Thoracic cancer

Lin L, Bai X, Ye X, Zhao X, Tan CH, Jiang Z.
PMID: 28925022
Angew Chem Int Ed Engl. 2017 Oct 23;56(44):13842-13846. doi: 10.1002/anie.201707899. Epub 2017 Oct 04.

The first catalytic asymmetric photoreduction of 1,2-diketones and α-keto ketimines under visible light irradiation is reported. A transition-metal-free synergistic catalysis platform harnessing dicyanopyrazine-derived chromophore (DPZ) as the photoredox catalyst and a non-covalent chiral organocatalyst is effective for these transformations....
