OBJECTIVE The concordance of KRAS mutation detection between the amplification refractory mutation system-Scorpion assay and direct sequencing was evaluated with clinically available formalin-fixed, paraffin-embedded specimens of metastatic colorectal cancers. METHODS Genomic DNA from 120 macrodissected specimens was examined by the amplification(More)
To investigate the potential value of targeting insulin-like growth factor-1 receptor (IGF-1R) in breast cancer, we examined the effects of NVP-AEW541, a selective small-molecule inhibitor of the IGF-1R tyrosine kinase, in a panel of 16 breast cancer cell lines. All cell lines expressed IGF-1R, but MCF-7 expressed much higher levels of insulin receptor(More)
BACKGROUND KRAS mutation testing is recommended for the discernment of metastatic colorectal cancer patients who are unlikely to benefit from anti-epidermal growth factor receptor antibodies. A recently developed amplification refractory mutation-Scorpion system is becoming a standard method for KRAS mutant detection. The feasibility and robustness of this(More)
Primary mucinous adenocarcinomas are uncommon, and their pathogenesis remains unclear. We recently reported the clinicopathologic characteristics of surgically resected mucinous adenocarcinoma, including the frequent involvement of the left and lower lung and absence of central fibrosis. The present study attempted to clarify the pathogenesis of mucinous(More)
